Description of the Invention: [Technical Field of the Invention] The present invention relates to a power generation system including an induction heating device that uses induction heating to convert rotational energy (mechanical energy) into thermal energy. The heat medium is heated; and the power generation unit converts the heat of the hot medium into electrical energy. [Prior Art] As a device for heating water, a heating device using induction heating (eddy current) has been proposed (for example, refer to Patent Document i). In the eddy current heating device described in Patent Document 1, a rotatable rotor in which a permanent magnet is disposed on the outer circumference and a flow path in which the outer circumference of the rotor is fixed and a flow of water is formed therein is provided. a heating portion of a conductive material. Then, by rotating the rotor, the magnetic force lines caused by the permanent magnets on the outer circumference of the rotor move through the heating portion, whereby eddy currents are generated in the heating portion, and the heating portion itself generates heat. As a result, the heat generated by the heating portion is conducted to the water flowing through the internal flow path, and the water is heated. • The above-mentioned technology is mainly aimed at the use of energy such as wind power to supply heat and water. In recent years, the same power generation system that utilizes renewable energy such as wind power, water power, and wave power has attracted attention. For example, in Non-Patent Documents 1 to 3, a technique relating to wind power generation is described. In wind power generation, the wind turbine is rotated by the wind, and the generator is driven to generate electricity. The wind energy is converted into rotational energy to be extracted as -5-201200729 electrical energy. A wind power generation system, generally constructed, is provided with a nacelle above the tower, and a horizontal axis windmill is mounted on the nacelle (the rotating shaft is a windmill that is slightly parallel with respect to the direction of the wind). In the nacelle, a speed increaser that increases the number of revolutions of the rotating shaft of the windmill and outputs it, and a generator that is driven via the output of the speed increaser are housed. The speed increaser is to increase the number of revolutions of the windmill to the number of revolutions of the generator (for example, 1:100), and is incorporated into the gear box. Recently, in order to reduce the cost of power generation, wind turbines (wind power generation systems) have been increased in size, and wind power generation systems having a diameter of 1 20 m or more and an output of 5 MW per machine have been put into practical use. Since such a large-scale wind power generation system is huge and extremely heavy, many constructions are built at sea from the viewpoint of construction. In the wind power generation, the power generation output (power generation amount) also fluctuates due to fluctuations in the wind power. Therefore, the power storage system is installed in the wind power generation system, and the unstable power is stored in the battery. Medium and smooth the output. [Prior Art Document] [Patent Document 1] Japanese Laid-Open Patent Publication No. 2005-174801 [Non-Patent Document] [Non-Patent Document 1] "Wind power generation (〇1 - 0 5 - 0 1 - 0 5 )" , [ ο η 1 ine ] 'Atomic Encyclopedia Dictionary ATOMICA (Searched on January 2, 2008) 201200729 , Internet <URL: http://www.rist.or.jp/atomica/> [Non-Patent Document 2] "2000 kW large-scale wind power generation system SUBARU80/2.0 PROTOTYPE", [online], Fuji Heavy Industries Co., Ltd., [Heicheng Searched on January 12, 22], Internet <URL: http://www.subaru-windturbine.jp/home/index.html> [Non-Patent Document 3] "Wind Lecture" (online), Mitsubishi Heavy Industries Co., Ltd., [January 12, 2005] Search], internet <URL :http://www. Mhi. Co. Jp/products/expand/wind_kouza. [Hereining] [Problems to be Solved by the Invention] In a wind power generation system that is generally known, a power storage system is provided to smooth the output. Therefore, parts such as converters are required, which leads to complication of the system and an increase in power loss. Further, in the case of a large-scale wind power generation system, a large-capacity storage battery is required in response to the amount of power generation, and the cost as a whole system increases. Moreover, most of the causes of failure of the wind power generation system are caused by failure of the speed increaser (specifically, the gearbox). In the case of a gearbox failure, the gearbox is usually exchanged for correspondence. However, when the nacelle is placed above the tower, it takes a lot of time and labor to install and remove the gearbox. Therefore, recently, there has been a gearless variable speed wind turbine that does not require an increased speed machine. However, in the case of gearless, specifically, it is to increase the number of poles of the power generation 201200729 (multi-pole generator), but the generator system is larger than the case of using the speed increaser. , weight. In particular, in a large-scale wind power generation system of 5 MW, it is conceivable that the weight of the generator is more than 300 tons (30,00000 kg), and it is difficult to arrange it in the nacelle. One of the objectives of the present invention is to provide a power generation system that uses induction heating to heat a heat medium and convert the heat of the heat medium into electrical energy to generate electricity. [Means for Solving the Problem] The power generation system according to the present invention includes: an induction heating device that converts rotational energy into heat energy by induction heating, and heats the heat medium; and the power generation unit The heat of the heat medium is converted into electrical energy. The power generation system of the present invention uses the heat of the heat medium heated by the induction heating device to generate electricity, but is not present in the prior art. A new power generation system. For example, if wind power is used in the power of the induction heating device, the energy of the wind can be converted into rotational energy and then converted into thermal energy, and taken out as electrical energy. On the other hand, the power generation system according to the present invention is configured to convert heat into electrical energy, thereby enabling energy to be stored as heat by using a heat accumulator, thereby realizing an efficient and stable power generation system. . Further, the heat storage system capable of accumulating heat in the heat accumulator and taking out the heat required for power generation is simpler than the power storage system, and the heat accumulator is also lower than the battery. -8 - 201200729 Further, it is not necessary to provide a speed increaser as in the prior art wind power generation system, and problems caused by the gear box can be avoided. In the present invention, the induction heating device is preferably one of the first to fourth aspects described below. A first aspect of the induction heating device in the power generation system of the present invention includes a rotor, a stator portion, a heating portion, a support column portion, a magnetic field generating means, a yoke portion, and a pipe, and each of the members is It is constructed like the following. The rotating body is fixed to one end side of the rotating shaft and is made of a magnetic material having a non-circular shape. The stator portion is disposed at a predetermined interval outside the rotating body, and is made of a magnetic material. The heating portion is disposed between the rotating body and the stator portion and is made of a conductive material. The support column portion is a columnar member that is disposed such that one end side thereof faces the one end side of the rotary body. The magnetic field generating means is mounted on the support post and generates a magnetic field for the rotating body. The yoke is made of a magnetic material and magnetically connects the stator portion and the other end side of the support post. The piping is disposed at the heating portion and has a heat medium circulating therein. This apparatus is formed by a magnetic field generating means to form a magnetic circuit that passes from one end side of the support column portion through the rotating body, the stator portion, and the yoke portion to the other end side of the support column portion. Further, by the rotation of the rotating shaft, the rotating system rotates, and the magnetic flux is changed by at least a portion of the heating portion disposed between the rotating body and the stator portion, whereby the heating portion is subjected to induction heating. Heat the heat media. A second aspect of the induction heating device in the power generation system according to the present invention includes: a rotating body having a rotating shaft; and a coil attached to the outer circumference of the rotating body of the front -9-201200729, and the rotating body a magnetic field is generated in the radial direction; and the heating portion is formed by at least a portion of the conductive material, and is disposed at intervals on the outer side of the rotating body, and has a magnetic flux caused by the coil; And the piping is provided in the heating unit, and the heat medium is circulated. The third aspect of the induction heating device in the power generation system of the present invention is in the form of a rotating body, a coil, a heating unit, and a pipe, and each of these members is configured as follows. The rotating body is formed, at least in part, by a combination of a magnetic material and a combination of a first rotating body having a rotating shaft and a second rotating body connected to the first rotating body. The coil is disposed between the first rotating body and the second rotating body so that the magnetic pole of one of the first rotating body and the second rotating body faces each other and rotates A magnetic field is generated in the direction of the axis of the body. At least one of the heating portions is made of a conductive material and is disposed at a distance from the rotating body at an outer side of the rotating body. The piping is disposed at the heating portion and has a heat medium circulating therein. Further, at both of the first rotating body and the second rotating body, at least one convex portion that protrudes in the radial direction of the rotating body is formed, and the convex portions of both of them are formed in the circumferential direction. In the offset state, the extension is set toward the opposite side, and they are separated from each other. The fourth shape of the induction heating device in the power generation system of the present invention. A state in which a rotating body having a rotating shaft, a convex portion provided on a peripheral surface of the rotating body, a stator portion, a heating portion, a coil, a pipe, and a heat insulating portion are provided, and each of the members is It is constructed as follows in general. The convex portion -10-201200729 portion is formed of a magnetic material and is provided to protrude from the outer surface of the rotating body toward the radial direction of the rotating body. At least one of the stator portions is made of a magnetic material and is disposed at a distance from the rotating body at the outer side of the rotating body. The heating portion is formed of at least a portion of a conductive material and disposed between the rotating body and the stator portion. The coil generates a magnetic flux that passes through the heating portion from the convex portion. The piping is placed at the heating unit and has a heat medium circulating therein. The heat insulating portion is disposed to cover the outer circumference of the stator portion. Further, in the induction heating device of the prior art described in the above-mentioned Patent Document 1, since a permanent magnet is used in a means for generating a magnetic field (magnetic field line), and this permanent magnet is disposed at the outer circumference of the rotor, The following general problems may arise. The induction heating energy is proportional to the square of the strength of the magnetic field (Η). However, in the case of permanent magnets, since the magnetic field that can be generated is generally weak, sufficient induction heating energy cannot be obtained. There is a tendency to heat the heat medium (such as a liquid such as water) to a desired temperature. In addition, in order to obtain a strong magnetic field, a neodymium magnet (see, in particular, paragraph 003 7 of Patent Document 1) may be considered. However, the thermal resistance of the ammonium magnet is poor, and if the temperature is increased, the magnetic properties are lowered. (This is the same for general ferrite magnets). In the induction heating device of the prior art described above, since the permanent magnet is disposed so as to face the heating portion, and the distance between the permanent magnet and the heating portion is close to each other, it is easy to be from the heating portion. The influence of the heat -11 - 201200729 causes the temperature of the permanent magnet to rise and the magnetic properties to decrease. As a result, there is a possibility that the heat medium cannot be heated to a desired temperature. Further, since the permanent magnet deteriorates the magnetic properties as time passes, it is difficult to withstand long-term use. Further, in order to prevent the deterioration (deterioration) of the magnetic properties due to heat, it is also conceivable to provide the heat insulating material so as to cover the outer circumference of the permanent magnet. However, in this case, since the heat insulating material is usually a non-magnetic material, the magnetic gap between the permanent magnet and the heating portion is larger than the predetermined one, and the total magnetic flux passing through the heating portion is reduced, so There will be a reduction in the efficiency of induction heating. First, in the induction heating device according to the first aspect described above, since the magnetic field generating means is attached to the support column portion disposed on one end side of the rotating body, the magnetic field is applied to the rotating body. The generating means is located at a position offset from the center of the rotating body in the axial direction. As a result, compared with the induction heating device of the prior art, it is possible to arrange the heating portion disposed between the rotating body and the stator portion and the magnetic field generating means so as to be separated from each other by a sufficient distance. The thermal influence caused by the heating means and the magnetic field generating means is suppressed. Further, in the induction heating device according to the first aspect, the magnetic field generating means is displaced in the axial direction with respect to the rotating body, and the magnetic field generating means is not surrounded by the rotating body, and The magnetic field generating means is attached to the support column portion which is fixed without rotation, and when a coil (electromagnetic stone) is used for the magnetic field generating means, for example, it is easy to handle the power source connected to the wire. In addition, by providing the piping in a heating unit that is fixed without being rotated -12-201200729, the piping and piping for supplying and discharging the heat medium to the piping phase do not require the use of the piping. The rotating swivel is constructed to achieve a strong connection. Specifically, if it is hot, the pressure in the piping rises. For example, in the case of a heat medium, it will reach about 25 MPa at 600 ° C. When the heating unit (pipe) rotates, it is special. However, when the rotary joint is not rotated and the rotary joint is not required, a sufficient method for welding the induction heating device according to the first aspect can be realized by a simple method such as welding. In this induction heating device, a magnetic flux (magnetic field) is generated in the system, and a magnetic circuit that passes from the support side through the rotating body, the stator portion, and the yoke portion to the one end side is formed. However, the rotating body gap (distance) changes by a portion between the non-circular rotating body and the stator portion. Specifically, when the rotational bone distance becomes narrow and the amount of flow between the rotating body and the stator portion becomes a slight flux, it is easy to flow from the rotating body to the stator portion, and the rotating body and the stator portion are large. The discontinuous state between the rotating body and the stator portion makes it difficult to flow from the rotating body to the stator portion. The at least one magnetic field of the heating portion between the rotating body and the stator portion is changed, thereby causing the connection of the induced current and the connection from the outside. The addition is water (vapor): 250 atmospheres). In order to be able to withstand this compression, the piping and piping are firmly constructed. The heat medium is heated by the magnetic field to generate one end of the column portion. The other rotating body of the column supports the rotation between the stator and the stator, and the distance between the I-stator portions is continuous. On the other hand, when the distance between the two becomes wide, the magnetic flux is the result of the magnetic flux ((eddy current), plus -13-201200729, the heat is applied to the heat and the heat medium is heated. In the induction heating device according to the first aspect, the rotating body is not circular, and the distance between the period body and the stator portion in which the rotating body rotates once is not limited. The external shape is, for example, a corrugated shape, an elliptical shape, a polygonal shape, a cross shape, or a gear shape. In each of the second to fourth aspects described above, a coil (electromagnetic stone) is used in the magnetic field generating means. Compared with the prior art, a device having a permanent magnet is a magnetic field of the energy. Specifically, a stronger magnetic field is generated by energizing the wire, and the intensity of the magnetic field is adjusted by adjusting the current. Further, if a coil is used, it is difficult for the magnet to cause magnetic deterioration due to temperature rise or deterioration of magnetic properties over time. Further, in the heating portion, it is used for heat preservation. In the case where the heat insulating material is provided, the heat insulating material is disposed between the rotating body and the heating portion, and the distance between the hot portions is increased, and the energizing current is set to more easily maintain a sufficient magnetic field strength. By using a coil at the magnetic field, it is possible to obtain a sufficient performance to heat the heat medium to a temperature (for example, 100 ° C to 600 ° C, preferably 2 ° C.), in addition, it can be cited at the coil. In the induction heating device according to the fourth aspect, the outer stator portion is disposed so as to cover the outer circumference of the stator and the outer shape, and the outer shape is not limited to a rectangular shape. Etc. The thermal device, by, therefore, is capable of generating a strong flow, and is capable of reducing the thermal characteristics compared to the permanent characteristics, even if the rotating body is enlarged, the field generating means is suitable The DC current of the -3 to 50 °C of the power generation is a structure in which the entire device including the swivel-14-201200729 rotating body, the heating portion, and the stator portion is covered by the heat insulator. In the above-mentioned apparatus, it is also conceivable that only the periphery of the heating portion is covered by the heat insulating material. However, in this case, the distance (magnetic gap) between the convex portion and the heating portion is changed. Large, the total magnetic flux passing through the heating portion is reduced. On the other hand, 'in this device, by covering at least the outer circumference of the stator portion with a heat insulating material, it is possible to suppress the heat release from the device. The heat insulating material covering the periphery of the heating portion is omitted or thinned. Therefore, the magnetic gap between the convex portion and the heating portion can be reduced, and the total magnetic flux passing through the heating portion can be maintained. Since the heat insulating material around the heating portion can be omitted or simplified, the cross-sectional area of the heating portion can be increased, and the size and weight of the device can be reduced. Further, in each of the induction heating devices of the second to fourth aspects, similarly to the device of the first aspect, the pipe is provided in a heating portion that is fixed without being rotated, and is connected to the pipe. In the connection between the supply and discharge pipes and the piping from which the heat medium is supplied and discharged from the outside, it is not necessary to use a rotary joint that allows the rotation of the piping, and the connection can be made secure with a simple configuration. Description will be made on the heating of the heat medium in each of the induction heating devices of the second to fourth aspects. In the induction heating device according to the second aspect, by energizing the coil attached to the outer circumference of the rotating body, a magnetic field is generated in the radial direction of the rotating body, and the magnetic flux passes through the heating provided at the outer side of the rotating body. unit. Then, by rotating the coil together with the rotating body, the magnetic flux passing through the heating portion changes in the amount of -15-201200729, and an induced current is generated at the heating portion, whereby the heating portion is heated for induction and heat is applied. The media is heated. Further, in this device, it is preferable that the coils are arranged in plural in the circumferential direction of the rotating body, and the polarities of the adjacent coils are different from each other. According to this configuration, the direction of the magnetic flux passing through the heating portion of the device (the direction of the magnetic field applied to the heating portion) can be periodically reversed. As a result, the change in the magnetic flux (magnetic field) passing through the heating portion can be increased, and the heating efficiency can be improved. Further, the number of the coils is not particularly limited, but it is preferably four or more. When the coils are arranged in plural, they are preferably arranged at equal intervals in the circumferential direction of the rotating body. In the induction heating device according to the third aspect, by energizing the coil, the first rotating body facing the magnetic pole of one of the coils is magnetized to have the same polarity as one of the magnetic poles, and the coil is The other one of the magnetic poles is magnetized to have the same polarity as the other magnetic pole. As a result, the convex portions of both the first rotating body and the second rotating body are magnetized to have different polarities, and the convex portions of the both sides are formed at the cross section orthogonal to the axial direction of the rotating body. In the separated state, they are alternately arranged in the circumferential direction of the rotating body. Therefore, the polarities of the adjacent convex portions of the rotating body are different from each other. The magnetic flux that flows out from the convex portions of both the first rotating body and the second rotating body passes through a heating portion disposed on the outer side of the rotating body (convex portion). Then, by rotating the rotating body, the magnetic flux passing through the heating portion changes, and an induced current is generated at the heating portion, whereby the heating portion is inductively heated and the heat medium is heated. -16- 201200729 In addition, in this device, it is preferable that the convex portion is provided in a plurality of the first rotating body and the second rotating body (for example, two or more 'the total of the two is four or more In the case where the convex portions are provided in plural, it is preferable to provide them at equal intervals in the circumferential direction of the rotating body. In the induction heating device of the fourth aspect, by energizing the coil, A magnetic flux that passes through the heating portion from the convex portion provided at the rotating body is generated. Then, in this state, by rotating the rotating body, the magnetic flux passing through the heating portion changes, and an induced current is generated at the heating portion, whereby the heating portion is inductively heated and the heat medium is heated. In addition, in this apparatus, the convex part is only required to have at least one, and its position or shape is not limited. When the convex portions are arranged in a plural number, it is preferably four or more, and they are disposed at equal intervals in the circumferential direction of the rotating body. In each of the induction heating devices of the first to fourth aspects, the magnetic material used in the rotating body of the apparatus of the first aspect or the third aspect or the convex portion of the apparatus of the fourth aspect is, for example, iron. , nickel, cobalt, niobium steel, high magnetic alloy and ferrite. Further, examples of the conductive material used in the heating portion include aluminum, copper, iron, and the like. In particular, by using aluminum in the heating portion, the weight of the heating portion can be reduced, and the weight of the induction heating device can be further reduced. Examples of the heat medium include liquids such as water, oil, liquid metal (Na, Pb, etc.), molten salts, and gases. Hereinafter, an ideal embodiment of each of the induction heating devices -17 to 201200729 in the first to fourth aspects described above will be described. The induction magnetic field generating means according to the first aspect is a magnetic wire or a coil (electromagnetic stone) used in this device. In the case of using a permanent magnet, it is possible to use a coil in the means of production. The induction heating device of the fourth aspect is controlled by energizing the current by energizing the coil. Further, if a coil is used, the magnetic properties are deteriorated due to an increase in temperature. Further, in the case where the heat insulating material is provided around the circuit (specifically, the distance between the rotating body and the heating portion is large, the coil can be easily used to maintain the charging means, and the specific temperature (for example, 100) In the case of the coil - in the case of the coil, the form of the DC magnetic field can be cited. The induction of the first aspect: The stator portion is a cylindrical shape, and the protrusion is formed in a heart shape, and the heating device is preferably in the form of a heating device. The field generating means is a method in which a permanent magnet can be used when a coil is used, and a strong magnetic field is generated. The effect on the magnetic field is as described in the second aspect above. Specifically, the flow is increased, a stronger magnetic field can be generated, and the strength of the magnetic field can be adjusted compared to the permanent magnet. It is difficult to cause a decrease in characteristics or a diachronic magnetic property. When the heat is applied to the heating portion, even if the heat insulating material is disposed between the magnetic rotating body and the heating portion, and the distance is made larger, the magnetic field is set to be more divided by the energizing current. . Therefore, the magnetic system can be obtained by the heat medium is heated to a sufficient / 600 ° c) of sufficient magnetic field. In a preferred embodiment, when a DC power supply is connected to the coil and a heat generating device is used, it is exemplified and provided with a cylindrical portion from the cylindrical portion to be mounted on the inner circumference of the stator portion -18-201200729. The upper part is provided with a hole for inserting the protrusion. According to this configuration, the periphery of the protruding portion of the stator portion is surrounded by the conductive material forming the heating portion. Then, if the distance between the rotating body and the protruding portion of the stator portion is narrowed by the rotation of the rotating body, the distance between the rotating body and the protruding portion of the stator portion is narrow, and the magnetic flux flowing at the protruding portion is changed, and then around the protruding portion At the heating portion, induced electric power (reverse power) is generated, and a current is flown, and thereby heated. Therefore, according to this configuration, the heat medium can be heated by the induced electric power at the heating portion around the protrusion portion, and the protrusion portion can be used, and the protrusion portion is not present. In the case, the magnetic flux flowing from the rotating body to the stator portion (protrusion portion) increases as the distance between the rotating body and the stator portion (protrusion portion) becomes narrow. As a result, the change in the amount of magnetic flux flowing through the projections of the stator portion can be increased, and the generated induced electric power can be increased, and the heating efficiency can be improved. In a preferred embodiment of the induction heating device according to the first aspect, the shape of the rotating body is a gear shape including a convex portion that protrudes in the radial direction. According to this configuration, the magnetic flux passing through one portion of the heating portion periodically changes during the one rotation of the rotating body, and the strength of the magnetic field at this portion periodically changes. Further, by narrowing the width of the convex portion in the circumferential direction of the rotating body, the magnetic flux flowing from the rotating body (the convex portion) to the stator portion is concentrated, and the magnetic flux (magnetic field) passing through the heating portion can be increased. Big. As a result, the change in the magnetic field at the heating portion can be increased, and the heating efficiency can be improved. In addition, the number of the convex portions is preferably -19 - 201200729, and more preferably 4 or more. In addition, when a plurality of convex portions are provided, for example, a form in which the rotating body is provided at equal intervals in the circumferential direction is preferable. As an ideal form of the second or third aspect of the induction heating device, The present invention includes a stator portion that is disposed on the outer circumference of the heating portion and is made of a magnetic material, and the stator portion is formed in a tubular shape, and has a projection portion that protrudes from the cylindrical portion and protrudes in a centripetal shape, and is heated. The portion is attached to the inner circumferential surface of the stator portion and has a hole through which the protruding portion is inserted. According to this configuration, as described above in the induction heating device of the first aspect in which the projection portion is provided at the stator portion, the conductive portion can be formed around the projection portion at the stator portion. The material is used to surround it. Then, for example, in the apparatus of the second aspect, the distance between the projections of the rotating body and the stator portion is narrowed by the rotation of the rotating body -> large or large - narrow, and the projection is made When the magnetic flux flowing in the space changes, the induced electric power (reverse power) is generated at the heating portion around the protrusion, and the current flows and is thereby heated. Therefore, according to this configuration, the heat medium can be heated by the induced electric power at the heating portion around the protrusion portion, and the protrusion portion can be used, and the protrusion portion is not present. In the case, the magnetic flux flowing from the coil to the stator portion (protrusion portion) increases when the distance between the coil and the stator portion (protrusion portion) becomes narrow. As a result, the change in the amount of magnetic flux flowing through the projections of the stator portion can be increased, and the generated induced electric power can be increased, and the heating efficiency can be improved. Further, in the case of the apparatus of the third aspect, the distance between the convex portion of the rotating body and the protruding portion of the stator portion of the -20-201200729 by the rotation of the rotating body becomes narrow-large or large-narrow. The effect of providing the projections on the stator portion is the same as that described in the induction heating device of the second aspect described above. In this case, the heat medium can be heated by the induced electric power at the heating portion around the protrusion, and by the presence of the protrusion, the rotation is performed as compared with the case where the protrusion is not present. The magnetic flux flowing from the convex portion to the protruding portion is increased when the distance between the body (protrusion) and the stator portion (protrusion portion) becomes small. As a result, the change in the amount of magnetic flux flowing through the projections of the stator portion can be increased, and the generated induced electric power can be increased, and the heating efficiency can be improved. Further, in the apparatus of the fourth aspect, it is preferable that the stator portion has a protruding portion that protrudes in a centripetal shape, and the heating portion is attached to the stator portion. The inner peripheral surface is provided with a hole through which the protruding portion is inserted. With such a configuration, it is possible to obtain the same operational effects as those described in the first to third aspects of the induction heating device in which the projections are provided in the stator portion. In the case of the induction heating device of the first to fourth aspects, when the projection portion is provided at the stator portion, the number of the projection portions is preferably plural, and more preferably four or more. Further, when a plurality of projections are provided, it is preferable to provide them at equal intervals in the circumferential direction of the stator portion. In each of the induction heating devices of the first to fourth aspects, when the stator portion is provided, examples of the magnetic material used in the stator portion include iron, nickel, cobalt, niobium steel, and high magnetic permeability. Alloys, ferrites, etc. - 201200729 As an ideal form of each of the induction heating devices of the first to fourth aspects, the magnetic field generating means is a coil, and the coil type is a superconducting coil. Examples of the coil include a constant conductance coil such as a copper wire or a superconducting coil using a superconducting wire. When a DC current flows in the coil and a DC magnetic field is generated, if the superconducting coil is used, the resistance is 〇, and even if a large current flows, heat (loss) is not generated at the coil. Therefore, compared with the constant conductance coil, it is possible to suppress the heat generation (loss) of the turns due to the flow of a large current, and even in a large space, it is possible to maintain a very strong magnetic field without power loss. Moreover, the current density of the superconducting wire rod is high, and it is possible to reduce the size and weight of the coil. Further, the induction heating device is reduced in size and weight. For example, when a large amount of thermal energy that can be matched to large-scale power generation is desired, by using a superconducting coil, the power consumption is smaller than that of the constant conducting coil, and the device can be miniaturized. Lightweight and easy to configure in the nacelle. Here, when the heat insulating portion is generally provided as in the device of the fourth aspect, the distance (magnetic gap) between the rotating body (the convex portion) and the heating portion can be reduced, even if it is a constant conducting coil. It is easy to obtain a magnetic field capable of sufficiently heating the heating portion (heat medium) to a specific temperature. In the heat insulating portion, for example, a heat insulating material such as asbestos, glass asbestos, foamed plastic, red brick, or ceramic can be used. In a preferred embodiment of each of the induction heating devices according to the first to fourth aspects, when the magnetic field generating means is a coil, it is possible to provide a protective coil of the protective-22-201200729 to be protected from the heat of the heating portion. The shape of the heat-resistant part. If the heating portion is heated, when the coil is placed at a position close to the heating portion, the temperature of the coil rises due to the heat of the heating portion. Further, it is conceivable that even if the coil is disposed at a position far from the heating portion, the heat is transmitted from the heating portion through the member such as the rotating body or the stator portion, and the wire is twisted. The temperature rises. If the temperature of the coil rises, there is a case where the electrical characteristics of the coil are deteriorated or the like. In particular, when a heat insulating portion is provided as in the fourth embodiment, the heat insulating material covering the periphery of the heating portion may be omitted or thinned, so that the influence is further enhanced. Become bigger. Therefore, according to this configuration, it is possible to prevent the temperature rise of the turns due to the heating of the heating portion, and it is possible to make the coil less susceptible to heat from the heating portion. In a preferred embodiment of each of the induction heating devices of the fourth to fourth aspects, a configuration in which a rotating shaft is connected to a windmill and wind power is used to rotate the rotating body is used. In each of the induction heating devices described above, it is preferable to use regenerative energy such as wind power, water power, and sea wave force in the power of the rotating body (rotating shaft). If the renewable energy is used, it is possible to suppress the increase of co2, and it is suitable to use wind power. [Effects of the Invention] The power generation system according to the present invention is capable of converting the heat of the heat medium heated by the induction heating device into electrical energy by the power generation unit and generating electricity -23-201200729. 'An embodiment of the present invention will be described. In addition, the same symbols in the drawings represent the same or equivalent parts. The power generation system of the present invention includes an induction heating device that heats a heat medium and a power generation unit that converts heat of the heat medium into electrical energy. Herein, the induction heating device will be described first, and then the entire power generation system will be described. <Induction heating device> [First embodiment] (Example 1) Figs. 1 to 1 are views for explaining the induction heating device of the first embodiment. The induction heating device 101' of the first embodiment shown in Figs. 1 and 2 includes a rotating body 11, a stator portion 12, a heating portion 13, a support column portion 16, and a magnetic field generating means 1. 5. The yoke portion 17 and the pipe 1 4 . The following description of the configuration of the induction heating device 10 1 1 will be described in detail. The rotating body 1 1 is fixed to one end side of the rotatably supported rotating shaft 2 1 , and the outer shape is viewed from the axial direction, and is formed to have a plurality of convex portions protruding in the radial direction. The gear shape of the portion 111. In this example, eight convex portions 1 1 1 are provided, and the convex portions are provided at equal intervals in the circumferential direction. The rotating body 11 is made of a magnetic material. In this example, a laminated steel plate in which a bismuth steel sheet is laminated in the direction of the rotation axis -24-201200729 is formed. In addition to this, it is also possible to use a powder magnetic core which is coated with an insulating coating on the surface of the magnetic powder such as iron powder and which is subjected to pressurization. In addition, in this case, the rotating body 11 is rotated in the counterclockwise direction (the arrow in FIG. 2(A) represents the direction of rotation, and FIG. 4(B) and FIG. 5 which are described later are also the same) . The stator portion 12 is disposed so as to cover the outer circumference of the rotating body 11, and is disposed at a predetermined interval from the rotating body 11. In this example, the stator portion 12 is cylindrical, and more specifically, cylindrical. The stator portion 12 is made of a magnetic material and is fixed to the heating portion 13 so as not to rotate, and is disposed between the rotating body 11 and the stator portion 12, and is rotated. The body 11 is formed into a cylindrical shape so as to cover the periphery. The heating portion 13 is made of a conductive material, and is formed of, for example, aluminum, a metal such as copper or iron. Further, the heating portion 13 is attached to the inner circumferential surface of the stator portion 12 without being rotated. At the heating unit 13, a pipe 14 through which a heat medium flows is provided (refer to Fig. 2 (A)). In this example, a plurality of flow paths extending in the axial direction are formed inside the heating portion 13, and these are used as the pipes 14 for circulating the heat medium. Further, the heating portion 13 and the pipe 14 are thermally connected. For example, in this example, the heat medium is supplied from one end side of the pipe 14 and discharged from the other end side, or the one end side of the pipe 14 is attached. A pipe connecting the pipe and the other pipe 14 is connected, and the heat medium is supplied from the other end side of the pipe 14 and is discharged from the other end side of the other pipe 14 by the connection pipe - 25-201200729. In the latter case, the heating distance of the media is increased as compared with the former. Further, a heat insulating material may be disposed around the heating portion 13). For example, in this example, a configuration in which the heat insulating material is provided in the end portions of the heating portion 13 and the end portion of the heating portion 13 except for the arrangement of the pipes 14 is exemplified. Among the heat insulating materials, for example, cotton, glass asbestos, foamed plastic, red brick, ceramic, and the like. The support column portion 16 is configured to have a columnar shape in which one end side thereof is opposed to the one end side of the rotary body, and is attached to the back surface of the rotary body 1 1 (the one end side thereof) A play hole 1 15 is formed, and in this play hole 1 15 , one end portion of the play portion 16 is referred to (refer to FIG. 2(B)). The support column portion is not particularly limited, and examples thereof include a cylindrical column shape, a polygonal column shape, and a polygonal column shape. In this example, the columnar shape is empty, and the weight is reduced. Further, the support column portion 16 is made of a magnetic material or a non-magnetic material, and is formed of a magnetic material in this example. For example, when the magnet or the constant conducting coil is used in the magnetic field generating means, it is preferable to support the column portion 16 by magnetic. On the other hand, when an overcharge condition is used, since the magnetic field generated by the saturation magnetic flux of the support column portion 16 is limited, the support column portion 16 is formed by the material. Things are more ideal. At the support column portion 16, a coil 15 is provided with a magnetic field generating means for the magnetic field of the rotating body, and the coil 15 is capable of heat (the stone can be used instead of the inner and outer peripheral surfaces). In the center, there is a cylindrical shape in the shape of the support column 16 and a system in the middle, which can be caused by the non-magnetic material to guide the coil to cause the non-magnetic material 11 to be produced. In the case of the rotating body 11 with respect to -26-201200729, it is placed from the center of the rotating body toward the axial direction. Further, 'at the coil 15' is connected to the unillustrated example in this case. The DC power control of the room is used to determine the direction of the generated magnetic field (magnetic flux). One end side (the side of the rotating body 1 1) becomes the N pole, and the other is the S pole. The coil I5 is the superconducting coil, and The cooling bushing is shown as being covered, and is cooled in a superconducting state. The yoke portion 17 is formed of a magnetic material and is a member for magnetically connecting the other end side of the fixed column portion 16.于部1,7 is equipped with: The end side is connected to the yoke piece 171 which is counted in the circumferential direction so as to cover the outer peripheral side of the coil portion 15 and the base plate 172 which is additionally connected to each of the yoke pieces 171. The other end side of the branch on which the coil 15 is attached is connected to the base plate 1 72, and the stator portion 12 and the support post portion 16 are additionally connected by the yoke portion 17. In this example, it is used. The yoke piece 171 1 7 may be formed by using one yoke piece which is continuous in the circumferential direction and continuous. Next, the production of the heat medium in the induction heating device 1011 will be described in detail. In the heating device 110, the magnetic flux (magnetic field) is generated by energizing the coil 15, and is formed from the support column-end side through the rotating body 1 1 , the stator portion 1 2, and the yoke portion 1 offset. DC power supply. The direction of the flow is made, and the outer end side is made to be surrounded by the left part 12 and the support, the yoke 12 and the configuration of the complex end side are connected to the column. In this case, the one end side can be made magnetic to form the yoke-shaped tubular body. Heat 7 (the yoke pieces 171 -27-201200729 and the base plate 172) of the DC pass portion 16 and the other end side circuit of the support column portion 16. That is, by the rotating body 1 1 and the stator The portion 1 2 and the yoke portion form a closed magnetic circuit (the dotted arrow in FIG. 2(B) is a schematic diagram showing the flow of the flux, and FIG. 7(A) is also the same, which is shown in FIG. 2(A). At a point, the convex portion 111 of the rotating body 11 and the stator are opposed to each other, and the narrow body Π and the stator portion 12 which are separated by the distance between the rotating body 1 1 and the stator portion 1 are slightly continuous, whereby magnetic As the size becomes smaller, the magnetic flux becomes easy to flow from the rotating body 11 to the stator. On the other hand, at the point b of Fig. 2(A), since the portion 1 1 is not stored, the rotating body 1 1-stall The rotating body 1 1 and the stator portion 12 in which the distance between the portions 12 are changed are in a discontinuous state, whereby the resistance becomes large, and the magnetic flux becomes difficult to flow from the rotating body 11 to 12. As a result, the magnetic flux passing through the circumference of the heating portion is changed by the rotation of the rotating body, and the intensity of the magnetic field at this portion is changed, whereby the induced current flow is generated at the heating portion 13) The heating unit 13 is inductively heated, and the heating medium in the pipe 14 is heated. Figure 3 is a graphical representation of the time of the magnetic field at point a of Figure 2 (A). When the magnetic field is the narrowest between the rotating body and the stator portion, the system becomes extremely large and maximizes. On the other hand, when the distance between the stator and stator portions becomes the largest, it becomes extremely small and is twisted in the induction heating device 1011. The convex portion 111' of the body 11 and the width of the convex portion 111 in the circumferential direction are magnetic 17 which is suitable for the magnetic field. In the 12-series system, the rotational impedance system portion 12 is provided in a wide range of the magnetic resistance stator portion 13 (the eddy current system is set by the amount of change in the minimum rotation amount). -28- 201200729 Here, By increasing the number of the convex portions 111 to some extent, the period of the magnetic field can be shortened. The induction heating energy (induced current) is proportional to the frequency of the magnetic field, and therefore, by the magnetic field The cycle is shortened, and the heating efficiency can be improved. Further, by narrowing the width of the convex portion 111 to some extent, the magnetic flux flowing from the rotating body 11 (the convex portion π 1 ) to the stator portion 12 is concentrated. The amount of magnetic flux that passes through the heating portion 13 corresponding to the position where the distance between the rotating body 11 and the stator portion 12 is narrow is increased. As a result, the amplitude of the magnetic field applied to the heating portion 13 is increased. The heating efficiency can be improved. (Example 2) The induction heating device 1 〇1 2 of the second embodiment shown in Figs. 4 and 5 has the shape of the stator portion and the heating portion and Figs. Implementation shown in The induction heating device 1 of the first embodiment is different from the first embodiment, and the stator portion 12 is provided with a cylindrical portion. The plurality of protrusions 121 are protruded in a centripetal shape, and the heating unit 13 is provided with a hole 131 through which the protrusions 121 are inserted. In this example, the stator unit 12 is provided with eight Each of the protrusions 121 is provided at equal intervals in the circumferential direction. Further, the protrusions 121 are parallel with respect to the axial direction of the stator portion 12, and are orthogonal to the protruding direction. The cross section which has been cut up is a rectangular column shape which is slightly rectangular, and the area of the cross section is a convex which is cut in a direction orthogonal to the protruding direction of the convex portion 111 of the rotating body 11. Section -29 - 201200729 The area of the face is slightly equal. If the machine for heating the heat medium at the induction heating device 1012 is described, it is applied to the heating unit by the rotation of the rotating body 1 1 . The intensity of the magnetic field at 1 3 is periodically changed, and by this An eddy current is generated in the portion 13, and the heating portion 13 is inductively heated, and the heat medium in the pipe I4 is heated. In this point, it is the same as the induction heating device 1011 of the first embodiment. Further, in the induction heating device At 1012, by the rotation of the rotating body 11, the distance between the convex portion Π 1 of the rotating body 1 1 and the protruding portion 1 2 1 of the stator portion 1 2 becomes narrow - wide or large - narrow, in the protruding portion The magnetic flux flowing in the space of 1 2 is changed (refer to FIGS. 5(A) and (B)). Thereby, the induced electric power (reverse power) is generated at the heating portion 13 around the protrusion 121, and flows. The electric current is thereby heated, and the heat medium in the pipe 14 is heated. As described above, at the induction heating device 1〇12, when the induced electric power is generated, the conductive material of the heating portion 13 existing around the protrusion 121 is formed around the protrusion 121. Since the continuous current path is different from the induction heating device 101 1 of the first embodiment, the heat medium can be heated by the induced electric power. In the induction heating device 1012 of the second embodiment, the shape of the projection 121 at the stator portion 12 is a substantially rectangular cross section when the cutting portion 121 is cut in a direction orthogonal to the protruding direction. The case of a quadrangular prism is described as an example, but it is not limited thereto. For example, as shown in Fig. 6, the projection portion 1 2 1 of the stator portion 12 can be formed in a skewed configuration with respect to the axial direction of the stator portion 12. By using the skew structure of -30-201200729, the cogging torque can be reduced, and the rotation of the rotating body 1 1 can be made smooth. Further, the convex portion 111 (Figs. 4 and 5) may be a skew structure. (Embodiment 3) In the above-described Embodiment 1 and 2, the induction heating device 1〇11, 1〇 is for the case where one coil 15 is attached to the support column portion 16 for explanation, but when induction is applied When the heating device is used in the present power generation system to be described later, it may be considered that the support column diameter is 1 m or more, for example, 2 m. Therefore, it is better to see that it is better to use a plural or a permanent magnet to form a means of life. In the induction heating device of the third embodiment of the first aspect shown in FIG. 7, the magnetic field generating means is formed by using a plurality of coils. For example, when a plurality of coils are used, as shown in FIG. A configuration in which a plurality of support column portions 16 are arranged in a cylindrical shape, and a column portion 16 is supported and a coil 15c is attached. With this configuration, by making the direction of the magnetic field generated by each coil 15 c the same, the induction heating device 1011 shown in FIG. 2(B) is formed, and one end side of the column portion 16 is formed to be rotated. The body 11, the stator portion 12 17 (the yoke piece 171 and the base plate 172) reach the magnetic circuit of the end side of the support column portion 16 (refer to Fig. 7 (A)). By using a complex number to form a magnetic field generating means, it is possible to separate one wire and one wire, and it is easy to manufacture a coil.

和與S極之線圈15相對向的部分處，磁通量（磁場）的方 向係爲相異。在與N極之線圈1 5相對向的部分（例如圖1 2 之a點）處，磁通量（磁場）的方向，係成爲從加熱部13 之內周側起而朝向外周側之方向（徑方向之+方向）。另 —方面，在與S極之線圏15相對向的部分（例如圖12之c點 )處，磁通量（磁場）的方向，係成爲從加熱部13之外周 側起而朝向內周側之方向（徑方向之一方向）。 圖1 3，係爲對於圖1 2之a點處的磁場之時間性變化作 模式性展示之圖。磁場，係當與N極之線圏相對向，且N 極之線圈-加熱部之間的距離成爲最爲狹小時，其強度在 +方向上會成爲最大。另一方面，磁場，係當與S極之線 圈相對向，且S極之線圏-加熱部之間的距離成爲最爲狹小 時，其強度在一方向上會成爲最大。亦即是，藉由使線圈 與旋轉體一同作旋轉，磁場之方向和強度，係一面週期性 地逆轉一面變化。 於此，在感應加熱裝置1021中，由於就算是當各線圈 1 5的極性係全爲相同（例如N極）的情況時，亦如同上述 —般，在與線圈1 5相對向的加熱部1 3之其中一部分處，磁 場係變強，而在與相鄰接之線圈1 5之間相對向的加熱部1 3 之另外一部分處，磁場係變弱。因此，藉由與旋轉體1 1 一 同地而使線圈1 5作旋轉，由於磁場之強度係作週期性的變 化，因此’加熱部1 3係被作感應加熱，配管1 4內之熱媒體 -39- 201200729 係被加熱。但是，於此情況，磁場之方向係並不會逆轉。 故而，在使相鄰接之線圈1 5的極性互爲相異的情況時，由 於磁場之方向係會逆轉，因此係能夠使被施加在加熱部13 處之磁場的振幅（變化）增大。其結果，係能夠在加熱部 1 3處而產生更大的感應電流，而能夠將加熱效率提升。 又，線圈15之數量，係可適宜作設定。於此，藉由將 線圈1 5之數量作某種程度的增加，係能夠將磁場之週期縮 短。感應加熱能量（感應電流），由於係與磁場之頻率間 存在有正比關係，因此，藉由將磁場之週期縮短’係能夠 將加熱效率提升。 進而，在線圈15處，係只要例如透過匯電環（slip ring )來與外部之電源作連接，並供給電流即可。 (實施例2 ) 圖1 4、1 5中所示之第2形態的實施例2之感應加熱裝置 1022，其之定子部以及加熱部之形狀係與圖11、12中所示 之實施例1的感應加熱裝置1 02 1相異，以下’以該相異點 爲中心來作說明。 在實施例2之感應加熱裝置1022中，定子部12’係具 備有從圓筒狀部分起而以向心狀來突出之複數的突起部 1 2 1，並且，在加熱部1 3處，係具備有使各突起部1 2 1作插 通之孔1 3 1。於此例中，定子部1 2係具備有8個的突起部 1 2 1，各突起部1 2 1，係在周方向上而被等間隔地作設置。 亦即是，線圈1 5之數量和突起部1 2 1之數量係爲相等◊又 -40- 201200729 ，突起部121，係相對於定子部12之軸方向而爲平行，並 且，係爲在與突出方向相正交的方向上作了切斷的剖面爲 呈略矩形狀之四角柱狀。 若是針對在感應加熱裝置1 022處之熱媒體被作加熱的 機制作說明，則係藉由與旋轉體11 一同地而使線圈1 5旋轉 ，而使通過加熱部1 3之磁通量作週期性變化，並在加熱部 1 3處產生感應電流，藉由此，加熱部1 3係被作感應加熱， 而配管1 4內之熱媒體係被加熱，在此點上，係與實施例1 之感應加熱裝置1021相同。進而，在感應加熱裝置1 02 2處 ，藉由旋轉體11之旋轉，線圈15和定子部12之突起部121 之間的距離係成爲狹小—廣大或者是廣大—狹小，在突起 部1 2 1處所流動之磁通量係變化（參考圖1 5 ( A ) 、 ( B ) )。藉由此，在突起部121周圍之加熱部13處，係產生感 應起電力（逆起電力），而流動電流，藉由此，加熱部13 係被加熱，配管1 4內之熱媒體係被作加熱。 如此這般，在感應加熱裝置1 022處，當產生有感應起 電力時，藉由存在於突起部121之周圍的加熱部13之導電 材料，由於在突起部121之周圍係被形成有連續之電流路 徑，因此，與實施例1之感應加熱裝置1 02 1相異地，亦能 夠利用感應起電力來將熱媒體加熱。 又，由於定子部1 2 (亦包含突起部1 2 1 )係藉由磁性 材料所形成，因此，在定子部1 2處係流動有磁通量。而’ 當各線圈15和各突起部121相對向時，從N極之線圈1 5所產 生的磁通量，係流動至與此線圈相對向之突起部1 2 1處’ -41 - 201200729 並通過定子部1 2之筒狀部分，而流動至與S極之線圈1 5相 對向的突起部1 2 1處（圖1 4 ( B )中之點線箭頭，係代表磁 通量之流動的示意圖）。亦即是。在旋轉體11和定子部12 處，由於係被形成有略封閉之磁路徑，因此，流動至各突 起部121處之磁通量係變大。 在此實施例2之感應加熱裝置1 022中，關於在定子部 12處之突起部121的形狀，係以成爲在與突出方向相正交 之方向上作了切斷時的剖面爲略矩形狀之四角柱狀的情況 爲例來作了說明，但是，係並不被限定於此。例如，如圖 16中所示一般，係可將定子部12之突起部121設爲相對於 定子部12之軸方向而作了傾斜的偏斜（skew)構造。藉由 採用偏斜構造，係能夠降低齒槽效應轉矩（Cogging Torque)，而使旋轉體11之旋轉成爲順暢。又，亦可將旋 轉體11之凸部111 (圖14、圖15)設爲偏斜構造。 在上述之實施例1、2的感應加熱裝置1021、1 022中， 雖係針對在加熱部1 3之內部形成流通路徑並且將加熱部13 和配管1 4作了一體化形成的情況爲例，而作了說明，但是 ，亦可將加熱部13和配管Μ相獨立地來形成之。於此情況 ，係以將配管亦藉由導電材料來形成爲理想。藉由將配管 經由導電材料來形成，係能夠將配管兼用爲加熱部。又， 亦可將加熱部和配管設爲獨立個體，並將配管設置在加熱 部之表面。於此，當將配管藉由導電材料來形成，並將配 管兼用爲加熱部的情況時，例如，係可僅配置配管，除此 之外，亦可在圓筒狀之支持台的表面上而將配管作安裝。 -42- 201200729 此時’亦可將圓筒狀之支持台藉由導電材料以外之材料來 形成之。 當將配管藉由導電材料來形成，並且僅配置有配管的 情況時’係亦可如同在上述之第1形態的感應加熱裝置處 而使用圖9所說明者一般地來構成。 又’當定子部爲具備有突起部的情況時，例如，亦可 如同在上述之第1形態的感應加熱裝置處所說明了的圖1 〇 中所例示一般，在突起部1 2 1之外周，將由導電材料所成 之配管Μ作捲繞安裝。於此情況，藉由將配管14之捲繞起 始部與捲繞終結部之端部彼此藉由連接導體來作電性連接 ’經由在突起部1 2 1處所流動之磁通量的變化，在配管]4 處係產生感應起電力’在配管14中係流動有電流，藉由此 ’配管14係被加熱，而配管14內之熱媒體係被加熱。 以上所說明了的第2形態之感應加熱裝置，由於係在 磁場產生手段中使用有線圈，因此，相較於先前技術之使 用有永久磁石的裝置，係能夠產生強力的磁場。特別是， 藉由採用超電導線圈，係能夠對由於流動大電流一事所導 致之線圈的發熱作抑制，又，亦能夠產生更強的磁場。又 ，藉由將加熱部（配管）設爲並不作旋轉的構造，例如在 與配管相通連並從外部而將熱媒體作供給、排出之供排管 和配管之間的連接中，係並不需要使用容許配管之轉動的 旋轉接頭，而能夠以簡易之構成來實現堅牢之連接。 [第3形態] -43- 201200729 (實施例1 ) 圖1 7〜23，係爲對於第3形態之感應加熱裝置作說明 之圖。圖1 7〜1 9中所示之第3形態的實施例1之感應加熱裝 置1 0 3 1，係具備有旋轉體1 1、和線圈1 5、和加熱部1 3、和 配管14、以及定子部12。以下，對於感應加熱裝置1031之 構成作詳細說明。 旋轉體11，係爲將具有被可旋轉地作支持的旋轉軸21 之第1旋轉體Ua和相對於此第丨旋轉體11 a而被作連接之第 2旋轉體lib的雙方之組合所成。在第1旋轉體11a和第2旋 轉體1 1 b之雙方處，係被形成有朝向旋轉體1 1之徑方向而 突出之複數的凸部Ilia、111b，雙方之各凸部111a、111b ，係以相互在周方向上作了偏移的狀態下而朝向對方側來 作延伸設置，並且相互作分離》亦即是，第1旋轉體11 a和 第2旋轉體1 lb，係以相互地使各凸部1 1 la、1 1 lb作咬合的 方式而被作對向配置。又，雙方之各凸部111a、111b，係 在旋轉體1 1之周方向上以等間隔而被作設置。於此例中， 在第1旋轉體1 la和第2旋轉體1 lb之各別處，係分別被形成 有8個的凸部，在旋轉體11處，係被設置有雙方合計16個 的凸部。又，旋轉體11 (第1旋轉體11a以及第2旋轉體lib )，係藉由鐵等之磁性材料所形成。另外，於此，旋轉體 1 1，係設爲在從旋轉軸2 1側作觀察時而於逆時針方向上作 旋轉者（圖1 9中之箭頭，係代表旋轉體1 1之旋轉方向，後 述之圖21(B)、圖22亦爲相同）。 線圈1 5，係以在第1旋轉體1 1 a和第2旋轉體1 1 b處而使 -44- 201200729 其中一方之磁極和另外一方之磁極相對向的方式，來配置 在第1旋轉體1 1 a和第2旋轉體1 1 b之間，並在旋轉體1 1之軸 方向上產生磁場。亦即是，當被配置在旋轉體11之內部的 線圈15由於通電而被作了激磁時，與其中一方的磁極相對 向之第1旋轉體11a，係被磁化爲與其中一方之磁極相同的 極性，並且，與另外一方的磁極相對向之第2旋轉體1 1 b， 係被磁化爲與另外一方之磁極相同的極性。此時，第1旋 轉體11a以及第2旋轉體lib之各凸部111a、111b亦係被磁 化。在此線圈丨5處，係被連接有未圖示之直流電源。於此 例中，線圏1 5係爲超電導線圈，對於在線圏1 5處所通電之 直流電流的方向作控制，來決定所產生之磁場（磁通量） 的方向，並設爲使其中一方之磁極成爲N極，而使另外一 方之磁極成爲S極。又’超電導線圈15，係將周圍藉由未 圖示之冷卻用襯套來作覆蓋，而經由進行冷卻一事來保持 在超電導狀態下。 於此例中’第1旋轉體1 1 a和第2旋轉體1 1 b，係透過被 配置在中央內部之柱狀的連結構件1 22而被作連結，連結 構件1 1 2 ’係被插通於線圈1 5之內側，並且將線圈丨5作支 持（參考圖1 8 )。作爲形成連結構件1 1 2之材料，不論是 磁性材料、非磁性材料均可，只要是具備有機械性強度並 且能夠將線圈1 5作支持的材料即可，又以在構造強度和長 期耐候性上爲優良之材料爲理想。例如，係可列舉出在構 造用材料中所被使用的鐵、鋼、不鏽鋼、鋁合金、鎂合金 、GFRP (玻璃纖維強化塑膠）或者是cFRp (碳纖維強化 -45- 201200729 塑膠）等之複合材料。 於此’連結構件1 1 2，係藉由非磁性材料所形成。例 如’當將連結構件1 1 2藉由磁性材料來形成的情況時，由 於會有因爲連結構件1 1 2之磁通量飽和而導致超電導線圈 1 5所產生之磁場被作限定之虞，因此，亦會有以藉由非磁 性材料來形成連結構件1 1 2 —事爲較理想的情況。又，連 結構件1 1 2之形狀，例如，係可列舉出圓柱狀、圓筒柱狀 、多角柱狀、多角筒柱狀等，只要適當地因應於需要而選 擇理想之形狀即可。 加熱部1 3，係在旋轉體1 1之外側處，與旋轉體1 1空出 有間隔地被作設置，並以將旋轉體1 1之周圍作覆蓋的方式 而被形成爲简狀。在此加熱部1 3處，如同後述一般，係通 過有從旋轉體11之凸部111a、111b所流出的磁通量。又， 加熱部1 3，係藉由鋁等之導電材料所形成。 在加熱部13處，係被設置有流通有熱媒體之配管14( 參考圖1 9 )。在此例中，係在加熱部1 3之內部形成沿著軸 方向而延伸之複數的流通路徑，並將此些利用爲流通熱媒 體之配管1 4。而，加熱部]3和配管1 4係被作熱性連接。例 如，在此例中，係可列舉出：設爲從配管1 4之其中一端側 來供給熱媒體並從另外一端側而排出之構成，或者是設爲 在配管1 4之其中一端側安裝有將配管1 4和其他配管.1 4作連 接之連接管，並從配管〗4之另外一端側來供給熱媒體’而 透過連接管來從其他的配管1 4之另外—端側而排出之構成 。亦即是，前者之情況’係爲單方向流路’後者之情況’ -46- 201200729 則係成爲往返流路，相較於前者之情況，係以後者之情況 而能夠將熱媒體之加熱距離更爲增長。 又，在加熱部1 3之周圍，係亦可爲了將加熱部1 3作保 溫，而配置絕熱材（未圖示）。例如，在此例中，係可列 ‘ 舉出在加熱部13之內外周面以及加熱部13之端面中的除了 • 配管1 4之配置場所以外的場所處而設置絕熱材之構成。在 絕熱材中，例如係可使用石綿、玻璃石綿、發泡塑膠、紅 磚、陶瓷等。 當在加熱部13之周圍配置有絕熱材的情況時，由於被 磁化了的旋轉體1 1之凸部1 1 1 a、1 1 1 b和加熱部1 3之間的距 離係變大，因此，通過加熱部1 3之磁通量係減少，亦即是 ，被施加在加熱部1 3處之磁場係減少。在第3形態之感應 加熱裝置中，由於係使用有線圈15，因此，原本之磁場強 度即爲高，又，亦能夠因應於需要而將通電電流增大以將 磁場強度提高，因此，就算是在配置有絕熱材的情況時， 亦易於得到用以將熱媒體加熱至在發電中所需要之溫度所 需的充分之性能（熱能量）。此點，當在上述之第1或第2 形態的感應加熱裝置中之磁場產生手段係爲線圈的情況時 . ，亦爲相同。 定子部12，係爲被配置在加熱部13之外周的筒狀之構 件，並在內周面處被安裝有加熱部1 3。而，加熱部1 3以及 定子部I2，係以不會旋轉的方式而被作固定。 於此例中，定子部1 2係爲圓筒狀，並藉由磁性材料而 形成。在定子部1 2處，例如，亦可使用：將矽鋼板作了層 -47- 201200729 積的層積鋼板、或者是在鐵粉等之磁性粉末的表面上施加 絕緣被覆並且將此粉末作了加壓成形之壓粉磁心。 接著，針對在感應加熱裝置1031中的熱媒體之加熱機 制作詳細說明。 在感應加熱裝置1 0 3 1處，藉由對於線圈1 5之通電，線 圈15係被激磁，並在旋轉體11之軸方向上產生磁場，與線 圈15之其中一方的磁極（N極）相對向的第1旋轉體11a， 係被磁化爲N極，並且，與線圈15之另外一方的磁極（S極 )相對向的第2旋轉體1 lb，係被磁化爲S極。其結果，第1 旋轉體1 la之凸部1 1 la係被磁化爲N極，第2旋轉體1 lb之凸 部111b係被磁化爲S極，在與旋轉體11之軸方向相正交的 剖面處，由於雙方之凸部1 1 1 a、1 1 1 b係在作了分離的狀態 下而在旋轉體11之周方向上被交互地作配置，因此，旋轉 體1 1之相鄰接的凸部之極性，係互爲相異（特別是參考圖 19)。從第1旋轉體11 a和第2旋轉體lib之雙方的凸部111a 、111b所流出的磁通量，係通過被配置在旋轉體11 (凸部 )之外側處的加熱部1 3。而後，藉由使旋轉體1 1旋轉，通 過加熱部1 3之磁通量係變化，並在加熱部1 3處產生感應電 流，藉由此，加熱部1 3係被作感應加熱，配管1 4內之熱媒 體係被加熱。 於此，在感應加熱裝置1 03 1中，由於旋轉體1 1的相酃 接之凸部的極性係互爲相異，因此，在加熱部13之與凸部 1 1 1 a ( N極）相對向的部分和與加熱部1 3之凸部1 1 1 b ( S極 )相對向的部分處，磁通量（磁場）的方向係爲相異。在 -48- 201200729 與N極之凸部llla相對向的部分（例如圖19之a點）處’磁 通量（磁場）的方向，係成爲從加熱部1 3之內周側起而朝 向外周側之方向（徑方向之+方向）。另一方面，在與S 極之凸部111b相對向的部分（例如圖19之b點）處，磁通 量（磁場）的方向，係成爲從加熱部1 3之外周側起而朝向 內周側之方向（徑方向之-方向）。 圖20，係爲對於圖〗9之a點處的磁場之時間性變化作 模式性展示之圖。磁場，係當與N極之凸部相對向，且N 極之凸部-加熱部之間的距離成爲最爲狹小時，其強度在 +方向上會成爲最大。另一方面，磁場，係當與S極之凸 部相對向，且S極之凸部-加熱部之間的距離成爲最爲狹小 時，其強度在-方向上會成爲最大。亦即是，藉由以旋轉 體1 1旋轉來使凸部作旋轉移動，磁場之方向和強度，係一 面週期性地逆轉一面變化。 又，凸部111a、111b之數量，係可適宜作設定。於此 ，藉由將凸部1 1 1 a、1 1 1 b之數量作某種程度的增加，係能 夠將磁場之週期縮短。感應加熱能量（感應電流），由於 係與磁場之頻率間存在有正比關係，因此，藉由將磁場之 週期縮短，係能夠將加熱效率提升。 進而，線圈1 5，例如係只要從被形成在第1旋轉體1 1 之中央處的開口部1 1 3來將繞線拉出，並與外部之電源作 連接即可。當與旋轉體1 1 一同地而使線圈1 5作旋轉的情況 時，例如只要透過匯電環來將繞線與外部電源作連接即可 。又，亦能夠以就算是旋轉體1 1作旋轉亦並不使線圈1 5作 -49- 201200729 旋轉的方式，來在連結構件1 1 2與線圈1 5之間安裝軸承’ 並將繞線與外部電源作連接。 (實施例2 ) 圖21、22中所示之第3形態的實施例2之感應加熱裝置 1032，其之定子部以及加熱部之形狀係與圖17〜19中所示 之實施例1的感應加熱裝置1 〇3 1相異，以下’以該相異點 爲中心來作說明。 在實施例2之感應加熱裝置1032中，定子部12’係具 備有從圓筒狀部分起而以向心狀來突出之複數的突起部 121，並且，在加熱部13處，係具備有使各突起部121作插 通之孔131。於此例中，定子部12係具備有16個的突起部 1 2 1，各突起部1 2 1，係在周方向上而被等間隔地作設置。 亦即是，將凸部11 1 a和凸部1 1 1 b作了合計之旋轉子1 1的凸 部之數量，係和定子部12之突起部121的數量相等。又’ 突起部121，係相對於定子部12之軸方向而爲平行，並且 ，係爲在與突出方向相正交的方向上作了切斷的剖面爲呈 略矩形狀之四角柱狀。 若是針對在感應加熱裝置1 〇3 2處之熱媒體的加熱機制 作說明，則係藉由使旋轉體1 1旋轉，而使凸部1 1 1 a、1 U b 作旋轉移動，並藉由此而使通過加熱部1 3之磁通量作週期 性變化，並在加熱部1 3處產生感應電流，藉由此，加熱部 1 3係被作感應加熱，而配管1 4內之熱媒體係被加熱，在此 點上，係與實施例1之感應加熱裝置1 03 1相同。進而，在 -50- 201200729 感應加熱裝置l〇3 2處，藉由旋轉體11之旋轉，旋轉體11之 凸部和定子部12之突起部121之間的距離係成爲狹小—廣 大或者是廣大—狹小，在突起部1 2 1處所流動之磁通量係 變化（參考圖22(A) 、 ( B ))。藉由此，在突起部121 周圍之加熱部13處，係產生感應起電力（逆起電力），而 流動電流，藉由此，加熱部1 3係被加熱，配管1 4內之熱媒 體係被作加熱。 如此這般，在感應加熱裝置1 032處，當產生有感應起 電力時，藉由存在於突起部121之周圍的加熱部13之導電 材料，由於在突起部121之周圍係被形成有迴圈狀之電流 路徑，因此，與實施例1之感應加熱裝置1 0 3 1相異地，亦 能夠利用感應起電力來將熱媒體加熱。 又，由於定子部1 2 (亦包含突起部1 2 1 )係藉由磁性 材料所形成，因此，在定子部12處係流動有磁通量。而， 當各凸部111a、lUb和各突起部121相對向時，從N極之凸 部1 1 1 a所流出的磁通量，係流動至與此凸部1 1 1 a相對向之 突起部121處，並通過定子部12之筒狀部分，而流動至與S 極之凸部111b相對向的突起部121處（圖21(B)中之點線 箭頭，係代表磁通量之流動的示意圖）。亦即是，由於係 被形成有從N極之凸部111a起而通過定子部12並到達S極之 凸部1 1 1 b處的磁路徑，因此’流動至各突起部1 2 1處之磁 通量係變大。 在此實施例2之感應加熱裝置1 03 2中，關於在定子部 12處之突起部121的形狀’係以成爲在與突出方向相正交 -51 - 201200729 之方向上作了切斷時的剖面爲略矩形狀之四角柱狀的情況 爲例來作了說明，但是，係並不被限定於此。例如，如圖 23中所示一般，係可將定子部12之突起部121設爲相對於 定子部1 2之軸方向而作了傾斜的偏斜（skew )構造。藉由 採用偏斜構造，係能夠降低齒槽效應轉矩（Cogging Torque )，而使旋轉體11之旋轉成爲順暢。又，亦可將旋 轉體11之凸部（圖21、圖22)設爲偏斜構造。 在上述之實施例1、2的感應加熱裝置1031、1032中， 雖係針對在加熱部1 3之內部形成流通路徑並且將加熱部1 3 和配管1 4作了一體化形成的情況爲例，而作了說明，但是 ，亦可將加熱部1 3和配管1 4相獨立地來形成之。於此情況 ，係以將配管亦藉由導電材料來形成爲理想。藉由將配管 經由導電材料來形成，係能夠將配管兼用爲加熱部。又， 亦可將加熱部和配管設爲獨立個體，並將配管設置在加熱 部之表面。於此，當將配管藉由導電材料來形成，並將配 管兼用爲加熱部的情況時，例如，係可僅配置配管，除此 之外，亦可在筒狀之支持台的表面上而將配管作安裝。此 時，係亦可將筒狀之支持台藉由導電材料以外之材料來形 成。 當將配管藉由導電材料來形成，並且僅配置有配管的 情況時，係亦可如同在上述之第1形態的感應加熱裝置處 而使用圖9所說明者一般地來構成。 又，當定子部爲具備有突起部的情況時，例如，亦可 如同在上述之第1形態的感應加熱裝置處所說明了的圖1 〇 -52- 201200729 中所例示一般，在突起部121之外周，將由導電材料所成 之配管Μ作捲繞安裝。於此情況，藉由將配管14之捲繞起 始部與捲繞終結部之端部彼此藉由連接導體來作電性連接 ’經由在突起部1 2 1處所流動之磁通量的變化’在配管1 4 處係產生感應起電力，在配管1 4中係流動有電流，藉由此 ，配管14係被加熱，而配管14內之熱媒體係被加熱。 以上所說明了的第3形態之感應加熱裝置，由於係在 磁場產生手段中使用有線圈，因此，相較於先前技術之使 用有永久磁石的裝置，係能夠產生強力的磁場。特別是， 藉由採用超電導線圈，係能夠對由於流動大電流一事所導 致之線圈的發熱作抑制，又，亦能夠產生更強的磁場。又 ，藉由將加熱部（配管）設爲並不作旋轉的構造，例如在 與配管相通連並從外部而將熱媒體作供給、排出之供排管 和配管之間的連接中，係並不需要使用容許配管之轉動的 旋轉接頭，而能夠以簡易之構成來實現堅牢之連接。 [第4形態] (實施例1 ) 圖24〜28，係爲對於第4形態之感應加熱裝置作說明 之圖。圖24、25中所示之第4形態的實施例1之感應加熱裝 置1 04 1，係具備有旋轉體1 1、和定子部1 2、和加熱部1 3、 和線圈1 5、和配管1 4、以及絕熱部1 8。以下，對於感應加 熱裝置1 04 1之構成作詳細說明。 旋轉體1 1，係具備有被可旋轉地作支持之旋轉軸2 1， -53- 201200729 並在外周面上而將複數之凸部111於徑方向上而突出地作 一體性設置。於此例中，8個的凸部1 1 1，係在周方向上而 被等間隔地作設置。此旋轉體1 1，亦包含有凸部1 1 1地， 係由磁性材料所成，於此例中，係藉由在旋轉軸方向上而 將矽鋼板作了層積的層積鋼板來形成之。除此之外，亦可 使用：在鐵粉等之磁性粉末的表面上施加絕緣被覆並且將 此粉末作了加壓成形之壓粉磁心。另外，於此，旋轉體1 1 ，係設爲在從旋轉軸側來作觀察時而於逆時針方向上作旋 轉者（圖25(A)中之箭頭，係代表旋轉方向）。 定子部1 2，係爲在旋轉體U之外周側處，而與旋轉體 1 1之間空出有特定間隔地來作配置之筒狀的構件》於此例 中，定子部1 2係爲圓筒狀。此定子部1 2，係由磁性材料所 成，並以不會旋轉的方式而被作固定。 加熱部1 3，係被配置在旋轉體1 1和定子部1 2之間，於 此例中，係被形成爲圓筒狀。此加熱部1 3，係由導電材料 所成，例如係藉由鋁所形成。又，加熱部1 3，係被安裝在 定子部12之內周面上，而並不旋轉。 在加熱部1 3處，係被設置有流通有熱媒體之配管1 4 ( 參考圖2 5 ( A ))。在此例中，係在加熱部1 3之內部形成 沿著軸方向而延伸之複數的插通孔，並將配管14插通於各 插通孔中。而，加熱部13和配管14係被作熱性連接。又， 例如，在此例中，係可列舉出：設爲從配管I4之其中一端 側來供給熱媒體並從另外一端側而排出之構成，或者是設 爲在配管14之其中一端側處，安裝將配管14和其他配管14 -54- 201200729 作連接之連接管，並從配管1 4之另外一端側來供給 ，而透過連接管來從其他的配管14之另外一端側而 構成。亦即是，前者之情況，係爲單方向流路’後 況，則係成爲往返流路，相較於前者之情況’係以 情況而能夠將熱媒體之加熱距離更爲增長。 線圈1 5，係產生從凸部1 1 1而通過加熱部1 3之 。於此例中，線圈1 5，係被裝著在後述之支持柱部 並相對於旋轉體11而被配置在從旋轉體11之中心起 方向上作了偏移的位置處。又，此線圈1 5，係爲常 銅線圈，在線圈1 5處，係被連接有未圖不之直流電 此，係對於在線圈1 5處所通電之直流電流的方向作 來決定所產生之磁場（磁通量）的方向，並設爲使 之其中一端側（旋轉體1 1側）成爲N極，而使另外 成爲S極。 支持柱部1 6，係爲以使其之其中一端側與旋轉 其中一端側相對向的方式而被作配置之柱狀的構件 例中，係在旋轉體1 1之背面（其中一端側之面）中 形成有遊嵌孔1 1 5，在此遊嵌孔1 1 5中，係被遊嵌有 部16之其中一端部（參考圖25(B))。支持柱部 狀，雖並未被特別限定，但是，例如，係可列舉出 、圓筒柱狀、多角柱狀、多角柱筒狀等，於此例中 圓柱狀。又，支持柱部1 6，係可使用磁性材料、非 料之任一者，在此例中，係藉由磁性材料而形成。 當線圈1 5爲常電導線圏的情況時，係以藉由磁性材 熱媒體 排出之 者之情 後者之 磁通量 16處， 來在軸 電導之 源。於 控制， 線圈1 5 一端側 體11之 。於此 央處被 支持柱 16之形 圓柱狀 ，係爲 磁性材 例如， 料來形 •55- 201200729 成支持柱部1 6爲理想。另一方面，當線圈1 5爲超電導線圈 的情況時，由於會有因爲支持柱部16之飽和磁通量而導致 所產生之磁場被作限定之虞，因此，亦會有以藉由非磁性 材料來形成支持柱部1 6—事爲較理想的情況。 進而，感應加熱裝置1 04 1，係由磁性材料所成，並具 備有將定子部1 2和支持柱部1 6之另外一端側作磁性連接之 軛部1 7。於此例中，軛部1 7，係具備有：將其中一端側連 接於定子部12處並且以覆蓋線圈15之外周側的方式而在周 方向上被作了配置之複數的軛片171、和被與此些之各軛 片171的另外一端側作連接之基部板172。而，在被裝著有 線圈1 5之支持柱部1 6的另外一端側處，係被連接有基部板 172，藉由此，而能夠透過軛部17來將定子部12和支持柱 部1 6之另外一端側作磁性連接。在此例中，雖係使用複數 之軛片171來構成軛部17，但是，亦可使用於周方向上而 相連續之實質性筒狀的1個軛片來構成之。 絕熱部1 8，係以將定子部1 2之外周作覆蓋的方式而被 作配置，於此例中，係以將感應加熱裝置1 04 1之全體作包 圍的方式而被作配置。但是，在絕熱部18處，係在與旋轉 軸2 1或者是配管1 4相對應的場所，而設置有開口部。此絕 熱部1 8，例如係使用石綿、玻璃石綿、發泡塑膠、紅磚、 陶瓷等之絕熱材而形成之。 以上所說明了的感應加熱裝置1041，在基本上之構成 係與上述之第1形態的實施例1之感應加熱裝置1 〇 1 1相同， 關於在此裝置中之熱媒體被作加熱的機制，亦爲相同。 -56- 201200729 具體而言，在感應加熱裝置1041中，係藉由對線圈l5 進行通電，而產生磁場，並形成從支持柱部16之其中一端 側起來通過旋轉體11、凸部111、定子部12、軛部17(軛 片1 7 1以及基部板1 72 )並到達支持柱部1 6之另外一端側的 磁性迴路（圖2 5 ( B )中之點線箭頭，係對於磁通量之流 動的示意圖作展示）。亦即是，在凸部111和定子部12之 間，係產生磁通量，並產生從凸部111而通過加熱部13之 磁通量。於此，在圖25(A)之加熱部13的a點處，由於凸 部1 1 1 -定子部1 2之間的磁性間隙係變小，因此，通過加熱 部1 3之磁通量係增加。另一方面，在圖2 5 ( A )之加熱部 1 3的b點處，由於並不存在有凸部1 1 1，因此，磁性間隙係 變大，通過加熱部1 3之磁通量係減少。其結果，藉由旋轉 體1 1之旋轉，涵蓋加熱部1 23之全周而通過的磁通量係改 變，此部分處之磁場的強度係週期性的變化，藉由此，在 加熱部1 3處係產生感應電流（渦電流），加熱部1 3係被作 感應加熱，配管1 4內之熱媒體係被加熱。 圖26，係爲對於圖25 ( A )之a點處的磁場之時間性變 化作模式性展示之圖。磁場，當凸部-軛部間之磁性間隙 成爲最狹小時，係成爲極大且爲最大，另一方面，當凸 部-軛部間之磁性間隙成爲最廣大時，係成爲極小且爲最 小。 上述之感應加熱裝置1041，由於係在磁場產生手段中 使用有線圈，因此，相較於使用有永久磁石的情況，係能 夠安定地產生強力的磁場。又，由於絕熱部係被配置在定 -57- 201200729 子部之外周處，因此，係能夠將覆蓋加熱部之周圍的絕熱 材作省略或者是設爲較薄，而能夠將凸部和加熱部之間的 磁性間隙縮小，並且能夠取得加熱部之更大的剖面積。又 ，藉由將加熱部（配管）設爲並不作旋轉的構造，例如在 與配管相通連並從外部而將熱媒體作供給、排出之供排管 和配管之間的連接中，係並不需要使用容許配管之轉動的 旋轉接頭，而能夠以簡易之構成來實現堅牢之連接。 圖27，係爲對於上述之感應加熱裝置1041中的僅於加 熱部之周圍而配置了絕熱部的情況作展示之槪略側面剖面 圖。於此圖27所示之感應加熱裝置1 040中，絕熱部180係 具備有不會使熱從加熱部1 3而逸散之程度的厚度，例如， 絕熱部180之厚度，係爲50mm左右。故而，凸部111和加 熱部1 3之間的磁性間隙係變大，通過加熱部之總磁通量係 減少。又，對於感應加熱有所助益之加熱部1 3的剖面積亦 變小。相對於此，例如在圖25 ( B )所示之第4形態的感應 加熱裝置1 04 1中，藉由至少在定子部1 2之外周而配置絕熱 部1 8，係能夠對於從裝置而來之放熱作抑制，而能夠將覆 蓋加熱部之周圍的絕熱材作省略或者是設爲更薄。例如， 當亦在加熱部1 3之周圍配置絕熱材的情況時，係能夠將其 之絕熱材的厚度設爲5mm以下。故而，係將凸部1 1 1和加 熱部1 3之間的磁性間隙縮小，而能夠使通過加熱部1 3之總 磁通量增加。又，由於係能夠取得更大之加熱部1 3的剖面 積，因此，係能夠謀求裝置之小型輕量化。 於此例中，雖係將在基本構成爲與上述之第1形態的 -58- 201200729 實施例1之感應加熱裝置1011相同的裝置中而配置了絕熱 部的感應加熱裝置1 0 4 1爲例來作了說明，但是，例如，在 上述之第2或第3形態之感應加熱裝置中，係亦可配置上述 之絕熱部。藉由以覆蓋定子部之外周的方式來配置絕熱部 ，係能夠得到相同之作用效果。 又’在上述之感應加熱裝置1 〇 4 1中，雖係將線圈1 5爲 常電導線圈的情況作爲例子來作了說明，但是，線圈1 5係 亦可爲超電導線圏。當採用了超電導線圈的情況時，係能 夠產生更強的磁場。另外，如同上述一般，在感應加熱裝 置1 04 1中，由於係能夠將凸部1 1 1和加熱部1 3之間的磁性 間隙縮小，因此，就算是在常電導線圏的情況時，亦能夠 得到充分之用以將加熱部加熱的磁場。 除此之外，在感應加熱裝置1041中，凸部111的數量 ，以及在旋轉體11的周方向上之凸部111的寬幅，係可適 宜作設定。於此，藉由將凸部111之數量作某種程度的增 加，係能夠將磁場之週期縮短。感應加熱能量，由於係與 磁場之頻率存在有正比關係，因此，藉由將磁場之週期縮 短，係能夠將加熱效率提升。又，藉由將凸部11 1之寬幅 作某種程度的縮小，從凸部1 11所流動至定子部1 2處之磁 通量係集中，在與凸部11卜定子部1 2間之磁性間隙成爲狹 小的場所相對應之加熱部1 3處所通過的磁通量係增加。其 結果，被施加在加熱部1 3處之磁場的振幅係變大’而能夠 將加熱效率提升。 在感應加熱裝置1 〇 4 1中’由於係能夠將覆蓋加熱部13 -59- 201200729 之周圍的絕熱材省略或者是設爲較薄，因此，加熱部13之 熱係容易被傳導至旋轉體11或者是定子部12等之構件處。 因此’藉由將被設置在加熱部13處之配管14的熱媒體供給 側以例如能夠從定子部1 2來受熱的方式而作延伸配設，係 能夠將定子部1 2冷卻，並且能夠對於所產生的熱作有效利 用。又’在線圈1 5處，由於係使用有常電導線圈，因此， 藉由通電，線圈15係會發熱。因此，藉由將被設置在加熱 部1 3處之配管1 4的熱媒體供給側以例如能夠從線圈1 5來受 熱的方式而作延伸配設，係能夠將線圈1 5冷卻，並且能夠 謀求熱的有效利用。 (變形例1 -1 ) 在上述之感應加熱裝置1041中，係亦可如圖28(A) 中所示一般，使絕熱部1 8 a中介存在於旋轉軸2 1之途中。 若依據此構成，則係能夠對於加熱部1 3之熱經由旋轉體1 1 而從旋轉軸2 1所逸散一事作防止，而能夠將從裝置所產生 之放熱更進一步的降低。 (變形例1-2 ) 在上述之感應加熱裝置〗〇41中，係亦可如圖28(B) 中所示一般，設置對於線圈1 5作保護並免於使其受到加熱 部13之熱的影響之耐熱部19。此耐熱部19，係藉由上述之 絕熱材所形成。若依據此構成’則係能夠對於起因於加熱 部13被加熱一事所導致的線圈I5之溫度上升作防止，而能 -60- 201200729 夠使線圈1 5成爲難以受到從加熱部1 3而來之熱影響。另外 ，例如，在上述之第2或第3形態的感應加熱裝置中’係亦 可配置上述之耐熱部。 〈發電系統〉 接著，使用圖29，對於本發明之發電系統的全體構成 之其中一例作說明。圖29中所示之發電系統P，係具備有 感應加熱裝置1 〇、和風車20、和蓄熱器50、以及發電部60 。在被設置於塔91之上部的短臆92處，係被安裝有風車20 ，在短艙92內，係收容有感應加熱裝置10。又，在被建造 於塔91之下部（基台）的建屋93內，係設置有蓄熱器5 〇以 及發電部60。以下，對於發電系統P之構成作詳細說明。 感應加熱裝置1 〇，係利用感應加熱，來將旋轉能量（ 機械能量）變換爲熱能量，並將熱媒體作加熱，例如，係 可利用上述之第1〜第4形態中之其中一形態的感應加熱裝 置。又，在旋轉軸21之另外一端側，係被直接連結有後述 之風車20，並將風力利用爲使旋轉體作旋轉之動力。另外 ，於此，係以熱媒體爲水的情況爲例來作說明。 風車2 0，係爲以在水平方向上延伸之旋轉軸2 1爲中心 ，而將3枚之扇葉201以輻射狀而安裝在旋轉軸21上之構造 。在輸出爲超過5MW之風力發電系統的情況時，直徑係爲 120m以上，旋轉數係爲1〇〜20rpm左右。 在感應加熱裝置1 〇之配管處，係被連接有將水供給至 感應加熱裝置1 〇處之供水管73、和將藉由感應加熱裝置1 0 -61 - 201200729 而作了加熱的水送至蓄熱器5 0處之輸送管51。而，感應加 熱裝置1 〇，係藉由對於線圈作通電並使旋轉體作旋轉，而 使通過被配置在旋轉體和定子部之間的加熱部之磁通量變 化，藉由此，來對加熱部作感應加熱，並將配管內的水作 加熱。感應加熱裝置1 〇，由於係在磁場產生手段處使用有 線圏，因此，係能夠產生強的磁場，並能夠將身爲熱媒體 之水加熱至例如100°C〜600°c —般的高溫。又，感應加熱 裝置10，由於係將加熱部（配管）設爲並不作旋轉的構造 ，因此，係並不需要在配管和輸送管5 1以及供水管73之間 的連接中使用旋轉接頭，而能夠使用例如熔接等來以簡易 之構成而實現堅牢之連接。 此發電系統p，係藉由感應加熱裝置1 〇來將水加熱至 適於發電的溫度（例如20(TC〜3 50°c )，並產生高溫高壓 水。高溫高壓水，係通過將感應加熱裝置1 〇和蓄熱器50作 連接之輸送管51，而被送至蓄熱器50處。蓄熱器50，係將 通過輸送管5 1所送來之高溫高壓水的熱作儲蓄，並且，使 用熱交換器來將發電中所需要之蒸氣供給至發電部6 0處。 另外，亦可藉由感應加熱裝置1 〇來使蒸氣產生。 作爲蓄熱器5 0，例如，係可利用蒸氣蓄壓器、或者是 使用有熔融鹽或油等之顯熱型蓄熱器、亦或是利用有融點 爲高之熔融鹽的相變化之潛熱型蓄熱器。潛熱型之蓄熱方 式，由於係藉由蓄熱材之相變化溫度來進行蓄熱，因此， 一般而言，相較於顯熱型之蓄熱方式，其蓄熱溫度域係爲 狹帶域，而蓄熱密度係爲高。 -62- 201200729 發電部60，係爲將蒸氣渦輪機6 1和 的構造，並經由從蓄熱器50所供給而來 輪機61旋轉，而驅動發電機62並發電。 被送至蓄熱器50處之高溫高壓水或 復水器7 1而被冷卻並回復成水。之後， ，並成爲高壓水而通過供水管73來送至 ，藉由此，而進行循環。 若依據此發電系統P，則係將可再 力）作爲動力來得到旋轉能量並產生熱 蓄熱器中並發電，藉由此，就算是並不 ，亦能夠實現對應於需求之安定的發電 如同先前技術之風力發電系統一般而設 避免由於齒輪箱所造成的問題。進而， 經由輸送管來供給至例如被設置在塔之 發電部處，係並不需要在短艙中收容發 置於塔之上部的短艙小型化、輕量化。 在上述之發電系統中，雖係以在熱 的情況爲例來作了說明，但是，亦可將 率更高之液體金屬作爲熱媒體來使用。 ，例如係可列舉出液體金屬鈉。當將液 來使用的情況時，例如，係可設爲：在 收熱之一次熱媒體中使用液體金屬，並 輸送而來之液體金屬的熱來透過熱交換 (水）加熱，並使蒸氣產生。 發電機62作了組合 之蒸氣來使蒸氣渦 者是蒸氣，係藉由 係被送至幫浦72處 感應加熱裝置10處 生能量（例如，風 ，再將該熱蓄熱於 使用高價之蓄電池 。又，係並不需要 置增速機，而能夠 藉由將熱媒體之熱 下部（基台）中的 電部，而能夠將設 媒體中而使用了水 相較於水而熱傳導 作爲此種液體金屬 體金屬作爲熱媒體 用以從加熱部來接 藉由通過輸送管所 器而將二次熱媒體 -63- 201200729 又，當將在常壓下具有超過1 〇〇 °c之沸點的例如油、 液體金屬、熔融鹽等作爲熱媒體來使用的情況時，相較於 水，當一直加熱至特定之溫度（超過1 〇 〇 °c )時，係易於 對由於配管內之熱媒體的氣化所導致之內壓上升作抑制。 (試算例1 ) 使用如同圖30中所例示一般之模擬模型3000，來對於 在線圈3 2 0 0中使用了超電導線圏的情況和使用了銅線圈的 情況時之將初始成本和營運成本作了總和的總成本作試算 〇 模擬模型3 000，係爲在具有磁性間隙之C字狀的鐵芯 3 100上裝著有線圈3200的構造。鐵芯3100，其剖面係爲 400mmx500mm，間隙距離係爲l〇〇mm。 成本，係以下述之條件而作了計算。將運轉時間，設 爲一年4800小時（2 00天x24小時），並將電費設爲每千瓦 /小時1 5圓。又，對於線圏之消耗電力作考慮，並且，當 使用超電導線圈的情況時，係亦對於冷卻系統之運轉電力 作考慮，當使用銅線圈的情況時，則係進行水冷方式與空 冷方式之兩種類，並在水冷方式中亦對於水冷系統的之運 轉電力作考慮。在線圈處，係設爲流動有在磁性間隙中而 使.1T之磁場產生的電流。 於圖31中，對於總成本之試算結果作展示。於圖31中 ’將超電導線圈之總成本以實線作標示，並將水冷方式之 銅線圏（水冷銅線圏）的總成本以虛線作標示，而將空冷 -64- 201200729 方式之銅線圈（空冷銅線圈）的總成本以點線來作標示。 由此結果’可以得知，當使用了超電導線圈的情況時，相 較於水冷方向之銅線圈，雖然其之初始成本會變高，但是 ’由於消耗電力係爲小，因此，營運成本係變低，而在3 年左右之運轉年數後，總成本會逆轉。亦即是，在本發明 之發電系統的感應加熱裝置之磁場產生手段中，係以使用 超電導線圏的情況時，其相對於費用的單位效果爲更高， 而能夠抑制發電成本。 接著，在上述條件下，針對在圖30之模擬模型3 000的 線圈3 200中而使用了超電導線圏的情況和使用了銅線圈的 情況時之線圈重量作試算。但是，在水冷方式之銅線圈的 情況時，係將電流密度作爲1 0A/ mm2來計算，在空冷方 式之銅線圈的情況時，係將電流密度作爲1 A/ mm2來計算 ，又，在超電導線圈的情況時，係亦對於冷卻系統之重量 作考慮，當水冷方式之銅線圈的情況時，係亦對於水冷系 統的重量作考慮。 在對於線圈重量作了試算後，其結果，超電導線圈之 重量係爲200kg，水冷方式之銅線圏的重量係爲200kg，空 冷方式之銅線圈的重量係爲2000kg。由此結果，可以得知 ’相較於空冷方式之銅線圈，係以使用有超電導線圈的情 況時，能夠更謀求小型化、輕量化。亦即是，在本發明之 發電系統的感應加熱裝置之磁場產生手段中，係以使用超 電導線圈的情況時，能夠更謀求感應加熱裝置之小型化、 輕量化，並且，例如係成爲易於配置在短艙中。進而，當 -65- 201200729 在感應加熱裝置之磁場產生手段中而使用銅線圈的情況時 ，爲了將磁場增強，係成爲需要鐵芯，又，爲了對於鐵芯 之磁通量飽和作抑制，係不得不將鐵芯大型化，因此，相 較於超電導線圈，係無法避免感應加熱裝置之大型化、重 量化。 再加上，最近，伴隨著風車之旋轉而產生的低頻噪音 所對於人體造成的影響，係成爲問題。對於由風車所產生 之低頻噪音的降低對策，不僅是在國內，在海外亦有所檢 討，而週知有：藉由使風車作低速旋轉，係能夠抑制低頻 噪音。在本發明之發電系統的感應加熱裝置之加熱機制中 ，若是使旋轉體作低速旋轉，則所能夠得到之熱能量係會 減少，但是，藉由在感應加熱裝置之磁場產生手段中採用 超電導線圈，由於係能夠產生強力的磁場，因此，就算是 在低速旋轉下，亦能夠得到充分的熱能量。 另外，本發明，係並不被限定於上述之實施形態，在 不脫離本發明之要旨的範園內，係可適宜作變更。例如， 係可對於旋轉體或定子部之形狀適宜作變更，或者是亦可 對於形成旋轉體以及定子部之材料適宜作變更。 [產業上之利用可能性] 本發明之發電系統，係能夠適用在利用有可再生能量 之發電領域中。 【圖式簡單說明】 -66 - 201200729 [圖1

example, the invention of the 16 can be thought of magnetic field production 101 3 - for example. In each case, the coil is miniaturized as the other one from the support and the yoke. -31 - 201200729 In addition, when a plurality of permanent magnets are used, the general case is not illustrated, and the support column portion 16 is exemplified. A slit is formed in the circumferential direction, and a permanent magnet of 15 m is buried in each slit. According to this configuration, similarly, by making the directions of the magnetic fields of the permanent magnets 1 the same, the magnetic circuit can be formed in the same manner as the thermal device 10 1 1 shown in Fig. 2(B). The induction heating device 1011 to the above-described first to third embodiments is an example in which a flow path is formed inside the heating unit 13 and integrated with the pipe 14 as an example. The heating portion 13 and the pipe 14 are formed independently of each other. It is desirable to form the piping also by a conductive material. By forming it with a conductive material, the piping can be used for heating, and the heating unit and the piping can be made into separate bodies, and the surface of the piping can be provided. Here, when the pipe is formed of a conductive material and the tube is used as the heating portion, for example, the pipe may be disposed only on the surface of the cylindrical support table. A cylindrical support table can also be formed by a conductive material. FIG. 9 is a view showing an arrangement example of a pipe in a case where a pipe is formed by a conductive material, and is disposed at the inner circumferential surface of the cylindrical stator portion 1 2 . The case of the climbing arrangement is taken as an example. Fig. 9 is a flat view when the pipe 14 is viewed from the inner circumferential surface side, and the black arrow in Fig. 9 represents the supply of the heat medium. And in the induction plus 1 0 1 3 of the formation of the plural number 5c shown in Fig. 8, the heating unit 13 is clear, but in this case, the piping portion is used. Also, set it on heating and install the pipe in addition to this. Outer material and only with a plan. The piping 14 is a plan view of the sub-portion 12. Further, the discharge direction is -32-201200729. In the case of the one of the pipes 14, the entire circumference of the stator portion 12 is meandered in the circumferential direction. It is configured to be bent and formed. By causing the piping 14 to meander, the heating distance of the heat medium can be increased. In this case, the supply-side end portion and the discharge-side end portion of the pipe 14 are offset by a slight 360° in the circumferential direction, that is, the supply-side end portion and the discharge-side end portion are in position. The position in the circumferential direction is slightly the same. Therefore, the heated heat medium discharged from the discharge side end portion has a problem that the heat medium supplied from the supply side end portion is cooled and the heating efficiency is lowered. Therefore, the supply-side end portion and the discharge-side end portion of the pipe 14 are preferably shifted to some extent in the circumferential direction. For example, it is preferable to shift by 1 〇 or more. In the same manner as in Fig. 9(A), Fig. 9(B) is the same as Fig. 9(A), and the piping 14 is fitted in a serpentine state over the entire inner circumferential surface of the stator portion 12. Assume. In this case, the supply-side end portion and the discharge-side end portion of the pipe 14 are offset by a slight 180° in the circumferential direction. Further, in this example, the supply-side end portions of the adjacent pipes 14 and the discharge-side end portions are respectively located at positions slightly different in the circumferential direction. Therefore, the heated heat medium ** discharged from the discharge side end portion of the pipe 14 is not cooled by the heat medium supplied from the supply side end portion of the other pipe 14 . In the case of the four pipes I4, the same as the one shown in Fig. 9(B), the pipe 14 is disposed in a serpentine state on the entire inner circumferential surface of the stator portion. Further, the supply-side end portions -33 to 201200729 of the adjacent pipes 1 and the discharge-side end portions are located at positions slightly different in the circumferential direction. In this case, the supply-side end portion and the discharge-side end portion of the pipe 14 are offset by a slight 90 in the circumferential direction. In the case where the piping is arranged in a meandering state as described above, it is also possible to use a plurality of pipes. Further, in the example shown in FIGS. 9(A) to 9(C), the supply side end portion and the discharge side end portion of the pipe 14 are provided on one side in the axial direction of the stator portion 12, but The supply side end portion may be disposed on one side or the other side, and the discharge side end portion may be disposed on the other side or one side thereof. Further, in the case where the stator portion 12 is provided with the protrusion portion 1 2 1 as in the induction heating devices 1012 and 1 〇1 3 of the above-described second and third embodiments, it is assumed that the protrusion portion is held by the protrusion portion In the piping for the meandering, the connecting portions of the piping portions on the side opposite to the bent portion are separated from each other, and the connecting conductors 141 for electrically connecting the portions of the pipes to each other are additionally mounted (refer to the figure). It is preferable that the circumference of the protrusion 121 is surrounded by the pipe 14 and the connecting conductor 141 made of a conductive material, 9(D)). As a result, the current that occurs due to the induced electric power generated by the change in the magnetic flux flowing in the protrusion 121 is a loop shape formed by the pipe Μ and the connecting conductor 14 1 . The flow in the current path is again 'as the stator. In the case where the projection is provided, for example, as shown in Fig. 1A, a pipe made of a conductive material may be wound around the outer periphery of the projection 121. In this case, the connection between the winding start portion of the pipe 14 and the end portion of the winding end portion is electrically connected to each other by the connection conductor, via the magnetic flux flowing at the protrusion portion 121. In the change, the induced electric power is generated in the pipe 14, and a current flows in the pipe 14, whereby the pipe 14 is heated, and the heat medium in the pipe 14 is heated. In the induction heating device according to the first aspect described above, since the magnetic field generating means is positioned at a position shifted from the center of the rotating body toward the axial direction with respect to the rotating body, it can be disposed in the position The heating portion between the rotating body and the stator portion and the magnetic field generating means are disposed apart from each other with a distance therebetween, and the thermal influence on the magnetic field generating means from the heating portion can be suppressed. Further, by using the superconducting coil, it is possible to suppress the heat generation of the coil due to the flow of a large current, and it is also possible to generate a stronger magnetic field. In addition, the heating unit (pipe) is a structure that does not rotate, and for example, the connection between the supply pipe and the pipe that is connected to the pipe and supplies and discharges the heat medium from the outside is not It is necessary to use a rotary joint that allows the rotation of the pipe, and a strong connection can be realized with a simple configuration. [Second aspect] (Example 1) Figs. 1 to 16 are views for explaining the induction heating device of the second embodiment. The induction heating device 102 1 of the first embodiment shown in Figs. 1 and 1 is provided with a rotating body 1 1 , a coil 15 , a heating unit 13 , and a pipe 14 , and Stator portion 1 2 . Hereinafter, the configuration of the induction heating device 1 〇 2 1 will be described in detail. The rotating body 11 is provided with a rotatably supported rotating shaft 21'-35-201200729. The outer shape is viewed from the axial direction, and is formed to have a plurality of convex portions 111 protruding in the radial direction. Gear shape. In this example, the system has eight convex portions 111, and each convex portion 111 is provided in the circumferential direction and equally spaced. Further, on the outer circumference of the rotating body 11, a coil 15 to be described later is disposed. In addition, in this case, the rotating body 11 is rotated in the counterclockwise direction (the arrow in FIG. 12 represents the rotation direction, and FIG. 14 (B) and FIG. 15 which will be described later are the same). The material of the rotating body 1 1 may be any material that has mechanical strength and can support the coil 15 as long as it is a magnetic material or a non-magnetic material, and is excellent in structural strength and long-term weather resistance. Material. For example, a composite material such as iron, steel, stainless steel, aluminum alloy, magnesium alloy, GFRP (glass fiber reinforced plastic) or CFRP (carbon fiber reinforced plastic) used in the structural material can be cited. In this example, the rotating body 1 1 (including the convex portion 1 1 1 ) is formed of a non-magnetic material. When a normal conducting coil is used in the wire 圏15, it is preferable to form the rotating body 11 by a magnetic material. On the other hand, when a superconducting coil is used, since the generated magnetic field is limited due to the saturation magnetic flux of the rotating body 11, there is also a possibility of forming a rotation by a non-magnetic material. In the case of the body 1 1 , the wire 圏 1 5 ' is wound and mounted at each convex portion 丨 i 1 of the rotating body 1 1 and generates a magnetic field in the radial direction of the rotating body 11 . Further, a DC power supply (not shown) is connected to each of the coils. In this example, the direction of the direct current flowing through the coils 15 is controlled to determine the direction of the magnetic field (magnetic flux) generated by -36-201200729, and the polarity of the adjacent coils 15 is set. They are different from each other (refer to Figure 1 2). Further, each of the coils 15 is an ultra-electric coil, and the periphery is covered by a cooling bush (not shown), and is maintained in a superconducting state by cooling. The heating unit 13 is provided on the outer side of the rotating body 1 1 so as to be spaced apart from the rotating body 1 1 , and is formed in a cylindrical shape so as to cover the periphery of the rotating body 1 1 . At the heating portion 13, there is a magnetic flux caused by the coil 12. Further, the heating portion 13 is made of a conductive material, and is formed of, for example, aluminum, a metal such as copper or iron. At the heating unit 13, a pipe 14 through which a heat medium flows is provided (refer to Fig. 12). In this example, a plurality of flow paths extending in the axial direction are formed inside the heating portion 13 and these are used as the pipes 14 through which the heat medium flows. Further, the heating unit 13 and the pipe 14 are thermally connected. For example, in this example, a configuration is adopted in which a heat medium is supplied from one end side of the pipe 14 and discharged from the other end side, or a pipe 14 and other pipes 14 are attached. The connection pipe is connected, and the heat medium is supplied from the other end side of the pipe 14, and is discharged from the other end side of the other pipe 14 through the connection pipe. That is to say, the former case is a unidirectional flow path, and the latter case is a reciprocating flow path, and the heating distance of the heat medium can be increased more than the former case. Further, a heat insulating material (not shown) may be disposed around the heating portion 13. For example, in this example, the heat insulating material is provided in the outer peripheral surface of the heating portion 13 and the end surface of the heating portion 13 except for the place where the pipe 14 is disposed. Composition. In the heat insulating material, the stator portion 12 such as cotton, glass asbestos, foamed plastic, red brick, or ceramic is disposed in the heating portion 13, and the heating portion 13 is attached to the inner peripheral surface. Further, the stator portion 12 is fixed in such a manner that it does not rotate, and the stator portion 12 is formed in a cylindrical shape. When the stator portion 1 2 is formed of a magnetic material, a powder magnetic core in which an insulating coating is applied to a surface of a magnetic powder such as a laminated steel powder in which a bismuth steel sheet is laminated and press-formed may be used. A detailed description will be made on the machine in the induction heating device 1021. In the induction heating device 1021, a magnetic field is generated by the magnetic field in the radial direction of the coil rotating body 11, and the magnetic flux is generated. Here, in the opposite direction to the coil 15 and a part of the heating portion 13 of the coil 15 (for example, the magnetic flux of the point a and c of Fig. 12, the magnetic field becomes stronger. On the other hand, between the coils 15 The magnetic field is weakened by the opposite direction and the other portion of the distance from the coil 15 (for example, the point b of FIG. 12), and the heating portion 13 is covered by rotating the coil 15 and the rotation. The intensity of the magnetic field at the magnetic flux portion that passes through the whole cycle periodically changes. The induced current is generated at 13 points, whereby the heat of the heating portion is heated, and the heat medium in the pipe 14 is heated. The tubular structure of the outer circumference of the stone can be used, and the heating portion 13 and the heating portion 13 can be energized by a magnetic material, for example, a plate or iron and the powder is heated and heated. When the distance between the heating portions 13 is small, the magnetic flux of the heating portion 13 having a large adjacent line is reduced by the rotating body 1 1 , and the result is changed. In the heating unit 1 3 is used as induction plus -38- 201200729 again, in the induction heating device 1 In 02 1, since the polarities of the adjacent coils 5 are different from each other, the magnetic flux (magnetic field) is at a portion facing the coil 15 of the N pole and a portion facing the coil 15 of the S pole. The direction of the system is different. The portion of the magnetic flux (magnetic field) in the portion facing the coil 15 of the N pole (for example, a point in FIG. 1 2 ) is a direction from the inner peripheral side of the heating portion 13 toward the outer peripheral side (diameter direction) + direction). On the other hand, in the portion facing the line C of the S pole (for example, point c in FIG. 12), the direction of the magnetic flux (magnetic field) is from the outer peripheral side of the heating portion 13 toward the inner peripheral side. (one direction of the radial direction). Figure 13 is a graphical representation of the temporal variation of the magnetic field at point a of Figure 12. The magnetic field is opposite to the line N of the N pole, and the distance between the coil and the heating portion of the N pole becomes the narrowest, and the intensity becomes maximum in the + direction. On the other hand, when the magnetic field is opposed to the coil of the S pole and the distance between the turns and the heating portion of the S pole is the narrowest, the strength becomes maximum in one direction. That is, by rotating the coil together with the rotating body, the direction and intensity of the magnetic field are periodically reversed while changing. Here, in the induction heating device 1021, even when the polarities of the coils 15 are all the same (for example, N poles), the heating portion 1 facing the coil 15 is also used as described above. At some of the three, the magnetic field becomes stronger, and the magnetic field weakens at another portion of the heating portion 13 that faces the adjacent coil 15. Therefore, by rotating the coil 15 together with the rotating body 1 1 , since the strength of the magnetic field changes periodically, the 'heating unit 13 is heated by induction, and the heat medium in the pipe 14 is - 39- 201200729 is heated. However, in this case, the direction of the magnetic field does not reverse. Therefore, when the polarities of the adjacent coils 15 are different from each other, since the direction of the magnetic field is reversed, the amplitude (change) of the magnetic field applied to the heating portion 13 can be increased. As a result, a larger induced current can be generated at the heating portion 13, and the heating efficiency can be improved. Further, the number of the coils 15 can be suitably set. Here, by increasing the number of coils 15 to some extent, the period of the magnetic field can be shortened. Since the induction heating energy (induced current) has a proportional relationship between the frequency of the magnetic field and the magnetic field, the heating efficiency can be improved by shortening the period of the magnetic field. Further, the coil 15 may be connected to an external power source via a slip ring, for example, and supplied with an electric current. (Embodiment 2) The induction heating device 1022 of the second embodiment of the second embodiment shown in Figs. 4 and 15 has the shape of the stator portion and the heating portion and the embodiment 1 shown in Figs. The induction heating device 102 1 differs, and the following description will be centered on the difference. In the induction heating device 1022 of the second embodiment, the stator portion 12' is provided with a plurality of protrusions 1 1 1 protruding from the cylindrical portion in a centripetal shape, and at the heating portion 13 A hole 1 3 1 having the projections 1 2 1 inserted therein is provided. In this example, the stator portion 12 includes eight projections 1 2, and the projections 1 2 1 are provided at equal intervals in the circumferential direction. That is, the number of the coils 15 and the number of the protrusions 1 2 1 are equal to each other -40 - 201200729, and the protrusions 121 are parallel with respect to the axial direction of the stator portion 12, and are The cross section which is cut in the direction in which the protruding directions are orthogonal to each other is a quadrangular prism shape which is slightly rectangular. If the heat medium is heated in the induction heating device 1 022, the coil 15 is rotated together with the rotating body 11, and the magnetic flux passing through the heating portion 13 is periodically changed. An induced current is generated at the heating portion 13, whereby the heating portion 13 is inductively heated, and the heat medium in the pipe 14 is heated. In this regard, the sensing of the embodiment 1 is performed. The heating device 1021 is the same. Further, at the induction heating device 102 2, by the rotation of the rotating body 11, the distance between the coil 15 and the projection 121 of the stator portion 12 becomes narrow - large or large - narrow, at the projection 1 2 1 The magnetic flux flowing in the space changes (refer to Figure 15 (A), (B)). As a result, in the heating portion 13 around the protrusion 121, induced electric power (reverse power) is generated, and a current flows, whereby the heating unit 13 is heated, and the heat medium in the pipe 14 is For heating. In this manner, at the induction heating device 1 022, when the induced electric power is generated, the conductive material of the heating portion 13 existing around the protrusion portion 121 is formed continuously around the protrusion portion 121. Since the current path is different from that of the induction heating device 102 1 of the first embodiment, the heat medium can be heated by the induced electric power. Further, since the stator portion 1 2 (including the protrusion portion 1 2 1 ) is formed of a magnetic material, a magnetic flux flows in the stator portion 12 . And when the coils 15 and the respective protrusions 121 face each other, the magnetic flux generated from the coils 15 of the N pole flows to the protrusions 1 2 1 opposite to the coils - '41 - 201200729 and passes through the stator The cylindrical portion of the portion 1 2 flows to the projection 1 2 1 opposed to the coil 15 of the S pole (the dotted arrow in Fig. 14 (B) represents a schematic diagram of the flow of the magnetic flux). That is. At the rotating body 11 and the stator portion 12, since a slightly closed magnetic path is formed, the amount of magnetic flux flowing to each of the protruding portions 121 becomes large. In the induction heating device 1 022 of the second embodiment, the shape of the projection 121 at the stator portion 12 is a substantially rectangular shape when the cutting portion 121 is cut in a direction orthogonal to the protruding direction. The case of the square column shape is described as an example, but it is not limited thereto. For example, as shown in Fig. 16, the projection portion 121 of the stator portion 12 can be formed in a skew structure which is inclined with respect to the axial direction of the stator portion 12. By using the skew structure, the cogging torque can be reduced, and the rotation of the rotating body 11 can be made smooth. Further, the convex portion 111 (Figs. 14 and 15) of the rotating body 11 may have a skew structure. In the induction heating devices 1021 and 1 022 of the first and second embodiments described above, the case where the flow path is formed inside the heating unit 13 and the heating unit 13 and the pipe 14 are integrally formed is taken as an example. Although the description has been given, the heating portion 13 and the piping 亦可 can be formed independently of each other. In this case, it is desirable to form the piping also by a conductive material. By forming the pipe through a conductive material, the pipe can be used as a heating portion. Further, the heating unit and the piping may be independent individuals, and the piping may be provided on the surface of the heating unit. Here, when the piping is formed of a conductive material and the piping is used as the heating portion, for example, only the piping may be disposed, or in addition, on the surface of the cylindrical support table. Install the piping. -42- 201200729 At this time, the cylindrical support table can also be formed by materials other than conductive materials. When the piping is formed of a conductive material and only the piping is disposed, it can be configured as generally described with reference to Fig. 9 in the induction heating device of the first aspect described above. Further, when the stator portion is provided with the protruding portion, for example, as shown in FIG. 1A described in the above-described first embodiment of the induction heating device, the outer periphery of the protruding portion 1 2 1 may be The piping made of a conductive material is wound and mounted. In this case, the connection between the winding start portion of the pipe 14 and the end portion of the winding end portion is electrically connected to each other by the connecting conductor, and the magnetic flux flowing through the protruding portion 121 is changed in the pipe. In the case where the induced electric power is generated, a current flows through the pipe 14, whereby the pipe 14 is heated, and the heat medium in the pipe 14 is heated. In the induction heating device according to the second aspect described above, since the coil is used in the magnetic field generating means, a strong magnetic field can be generated as compared with the prior art using a permanent magnet. In particular, by using a superconducting coil, it is possible to suppress the heat generation of the coil due to the flow of a large current, and it is also possible to generate a stronger magnetic field. In addition, by the structure in which the heating unit (pipe) is not rotated, for example, in the connection between the supply pipe and the pipe which is connected to the pipe and supplies and discharges the heat medium from the outside, It is necessary to use a rotary joint that allows the rotation of the pipe, and a strong connection can be realized with a simple configuration. [Third aspect] -43 - 201200729 (Embodiment 1) Figs. 1 to 23 are views for explaining the induction heating device of the third aspect. The induction heating device 1 0 3 1 of the first embodiment shown in the third embodiment shown in FIGS. 7 to 19 includes a rotating body 1 1 , a coil 15 , a heating unit 13 , and a pipe 14 , and Stator portion 12. Hereinafter, the configuration of the induction heating device 1031 will be described in detail. The rotating body 11 is formed by combining a first rotating body Ua having a rotating shaft 21 rotatably supported and a second rotating body lib connected to the second rotating body 11a. . Both of the first rotating body 11a and the second rotating body 11b are formed with a plurality of convex portions Ilia and 111b that protrude toward the radial direction of the rotating body 1 1 , and the convex portions 111a and 111b of both of them are formed. The first rotating body 11 a and the second rotating body 1 lb are mutually coupled, so as to be extended toward the other side in a state of being offset from each other in the circumferential direction, that is, the first rotating body 11 a and the second rotating body 1 lb are mutually The convex portions 1 1 la and 1 1 lb are placed in a facing manner so as to be engaged. Further, the convex portions 111a and 111b of the both sides are provided at equal intervals in the circumferential direction of the rotary body 1 1. In this example, eight convex portions are formed in each of the first rotating body 1 la and the second rotating body 1 lb , and a total of 16 convex portions are provided in the rotating body 11 . unit. Further, the rotating body 11 (the first rotating body 11a and the second rotating body lib) is formed of a magnetic material such as iron. Further, here, the rotating body 11 is configured to rotate in the counterclockwise direction when viewed from the side of the rotating shaft 21 (the arrow in Fig. 19 represents the rotating direction of the rotating body 1 1 , 21 (B) and FIG. 22 which will be described later are also the same). The coil 15 is disposed in the first rotating body such that one of the magnetic poles of one of -44 to 201200729 and the other magnetic pole face each other at the first rotating body 1 1 a and the second rotating body 1 1 b A magnetic field is generated between the 1 1 a and the second rotating body 1 1 b in the axial direction of the rotating body 1 1 . In other words, when the coil 15 disposed inside the rotating body 11 is energized by energization, the first rotating body 11a facing the magnetic pole of one of the magnets is magnetized to be the same as the magnetic pole of one of the magnetic poles. The second rotating body 11b, which is opposite in polarity to the magnetic pole of the other one, is magnetized to have the same polarity as the other magnetic pole. At this time, the convex portions 111a and 111b of the first rotating body 11a and the second rotating body lib are also magnetized. At this coil 丨 5, a DC power source (not shown) is connected. In this example, the coil 15 is a superconducting coil, and the direction of the direct current generated by the coil 15 is controlled to determine the direction of the generated magnetic field (magnetic flux), and the magnetic pole of one of the magnetic poles is set to N pole, and the magnetic pole of the other side becomes the S pole. Further, the superconducting coil 15 is covered by a cooling bush (not shown) and maintained in a superconducting state by cooling. In this example, the first rotating body 1 1 a and the second rotating body 1 1 b are connected by a columnar connecting member 1 22 disposed inside the center, and the connecting member 1 1 2 ' is inserted. The inner side of the coil 15 is passed, and the coil turns 5 are supported (refer to Fig. 18). The material for forming the connecting member 1 1 2 may be a material having mechanical strength and capable of supporting the coil 15 as long as it is a magnetic material or a non-magnetic material, and has structural strength and long-term weather resistance. Ideal for excellent materials. For example, a composite material such as iron, steel, stainless steel, aluminum alloy, magnesium alloy, GFRP (glass fiber reinforced plastic) or cFRp (carbon fiber reinforced -45-201200729 plastic) used in the structural material may be cited. . Here, the connecting member 1 1 2 is formed of a non-magnetic material. For example, when the connecting member 1 1 2 is formed of a magnetic material, since the magnetic field generated by the superconducting coil 15 is limited due to saturation of the magnetic flux of the connecting member 112, It may be preferable to form the joint member 1 1 2 by a non-magnetic material. Further, the shape of the structural member 1 12 may be, for example, a cylindrical shape, a cylindrical column shape, a polygonal column shape, or a polygonal cylinder shape, and may be appropriately selected in accordance with the need. The heating unit 13 is provided on the outer side of the rotating body 1 1 so as to be spaced apart from the rotating body 1 1 and is formed in a simple shape so as to cover the periphery of the rotating body 1 1 . In the heating portion 13, the magnetic flux flowing out from the convex portions 111a and 111b of the rotating body 11 is passed through as will be described later. Further, the heating portion 13 is formed of a conductive material such as aluminum. At the heating unit 13, a pipe 14 through which a heat medium flows is provided (refer to Fig. 19). In this example, a plurality of flow paths extending in the axial direction are formed inside the heating portion 13 and these are used as the pipes 14 through which the heat medium flows. Further, the heating unit 3 and the pipe 14 are thermally connected. For example, in this example, the heat medium is supplied from one end side of the pipe 14 and discharged from the other end side, or one end side of the pipe 14 is attached. Will pipe 1 4 and other piping. 1 4 is used as a connecting pipe, and a heat medium is supplied from the other end side of the pipe 4, and is discharged from the other end side of the other pipe 14 through the connecting pipe. In other words, the former case is a one-way flow path 'the latter case' -46- 201200729 is a round-trip flow path, and the heat medium heating distance can be compared with the former case. More growth. Further, a heat insulating material (not shown) may be disposed around the heating portion 13 in order to keep the heating portion 13 warm. For example, in this example, a configuration in which a heat insulating material is provided in a place other than the place where the pipe 14 is disposed in the inner peripheral surface of the heating portion 13 and the end surface of the heating portion 13 can be listed. Among the heat insulating materials, for example, asbestos, glass asbestos, foamed plastic, red brick, ceramics, and the like can be used. When a heat insulating material is disposed around the heating portion 13, the distance between the convex portions 1 1 1 a, 1 1 1 b and the heating portion 13 of the magnetized rotating body 1 1 is large, so that the distance between the convex portions 1 1 1 a, 1 1 1 b and the heating portion 13 is increased. The magnetic flux passing through the heating portion 13 is reduced, that is, the magnetic field applied to the heating portion 13 is reduced. In the induction heating device according to the third aspect, since the coil 15 is used, the original magnetic field strength is high, and the energizing current can be increased to increase the magnetic field strength in response to the need, so that even In the case where the heat insulating material is disposed, it is also easy to obtain sufficient performance (heat energy) required to heat the heat medium to the temperature required for power generation. In this case, in the case where the magnetic field generating means in the induction heating device of the first or second aspect described above is a coil. , also the same. The stator portion 12 is a tubular member disposed on the outer circumference of the heating portion 13, and the heating portion 13 is attached to the inner peripheral surface. Further, the heating portion 13 and the stator portion I2 are fixed so as not to rotate. In this example, the stator portion 12 is formed in a cylindrical shape and formed of a magnetic material. At the stator portion 12, for example, a laminated steel sheet in which a bismuth steel sheet is layered -47-201200729 or an insulating coating is applied on the surface of a magnetic powder such as iron powder, and the powder is made. Pressure-molded powder core. Next, a detailed description will be made on the heating device of the heat medium in the induction heating device 1031. At the induction heating device 1031, the coil 15 is excited by energization of the coil 15, and a magnetic field is generated in the axial direction of the rotating body 11, as opposed to the magnetic pole (N pole) of one of the coils 15. The first rotating body 11a that is turned on is magnetized to the N pole, and the second rotating body 11b that faces the other magnetic pole (S pole) of the coil 15 is magnetized to the S pole. As a result, the convex portion 1 1 la of the first rotating body 1 la is magnetized to the N pole, and the convex portion 111 b of the second rotating body 11 lb is magnetized to the S pole and orthogonal to the axial direction of the rotating body 11 At the cross section, since the convex portions 1 1 1 a and 1 1 1 b of both sides are alternately arranged in the circumferential direction of the rotating body 11 in the separated state, the adjacent portions of the rotating body 1 1 The polarities of the connected convex portions are different from each other (see, in particular, FIG. 19). The magnetic flux flowing out from the convex portions 111a and 111b of both the first rotating body 11a and the second rotating body lib passes through the heating portion 13 disposed on the outer side of the rotating body 11 (convex portion). Then, by rotating the rotating body 1 1 , the magnetic flux passing through the heating unit 13 changes, and an induced current is generated in the heating unit 13 , whereby the heating unit 13 is inductively heated, and the inside of the pipe 1 4 The thermal media is heated. Here, in the induction heating device 101 1 , since the polarities of the convex portions of the spliced body of the rotating body 1 are different from each other, the convex portion 1 1 1 a (N pole) of the heating portion 13 The direction of the magnetic flux (magnetic field) is different at the portion facing the opposite portion and the portion facing the convex portion 1 1 1 b (S pole) of the heating portion 13. The direction of the magnetic flux (magnetic field) at a portion facing the convex portion 111a of the N-pole (for example, a point in FIG. 19) at -48-201200729 is from the inner peripheral side of the heating portion 13 toward the outer peripheral side. Direction (+ direction of the radial direction). On the other hand, in the portion facing the convex portion 111b of the S-pole (for example, at point b in Fig. 19), the direction of the magnetic flux (magnetic field) is from the outer peripheral side of the heating portion 13 toward the inner peripheral side. Direction (direction in the radial direction). Figure 20 is a graphical representation of the temporal variation of the magnetic field at point a of Figure 9. The magnetic field is opposed to the convex portion of the N pole, and the distance between the convex portion and the heating portion of the N pole becomes the narrowest, and the intensity thereof becomes maximum in the + direction. On the other hand, when the magnetic field is opposed to the convex portion of the S-pole and the distance between the convex portion and the heating portion of the S-pole is the narrowest, the intensity is maximized in the - direction. That is, the convex portion is rotationally moved by the rotation of the rotating body 11, and the direction and intensity of the magnetic field are periodically reversed while changing. Further, the number of the convex portions 111a and 111b can be appropriately set. Here, by increasing the number of the convex portions 1 1 1 a and 1 1 1 b to some extent, the period of the magnetic field can be shortened. The induction heating energy (induced current) is proportional to the frequency of the magnetic field. Therefore, by shortening the period of the magnetic field, the heating efficiency can be improved. Further, the coil 15 may be, for example, pulled out from the opening 1 1 3 formed at the center of the first rotating body 1 1 and connected to an external power source. When the coil 15 is rotated together with the rotating body 1 1 , for example, it is only necessary to connect the winding to the external power source through the power collecting ring. Further, it is also possible to mount the bearing ' between the connecting member 1 1 2 and the coil 15 even if the rotating body 1 1 is rotated or the coil 15 is rotated -49-201200729. The external power supply is connected. (Embodiment 2) The induction heating device 1032 of the second embodiment shown in Figs. 21 and 22 has the shape of the stator portion and the heating portion and the induction of the embodiment 1 shown in Figs. The heating device 1 〇3 1 is different, and the following description will be made focusing on the different points. In the induction heating device 1032 of the second embodiment, the stator portion 12' is provided with a plurality of protrusions 121 that protrude from the cylindrical portion in a centripetal shape, and the heating portion 13 is provided with Each of the projections 121 serves as a hole 131 through which the projections are inserted. In this example, the stator portion 12 is provided with 16 projections 1 2 1 , and the projections 1 2 1 are provided at equal intervals in the circumferential direction. That is, the number of the projections of the rotator 11 in which the convex portion 11 1 a and the convex portion 1 1 1 b are combined is equal to the number of the projections 121 of the stator portion 12. Further, the projections 121 are parallel with respect to the axial direction of the stator portion 12, and have a rectangular cross section in a substantially rectangular shape in a cross section perpendicular to the direction in which the projections are formed. In the case of the description of the heating device for the heat medium at the induction heating device 1 〇 3 2, the convex portions 1 1 1 a, 1 U b are rotationally moved by rotating the rotating body 11 and by Thereby, the magnetic flux passing through the heating unit 13 is periodically changed, and an induced current is generated in the heating unit 13, whereby the heating unit 13 is inductively heated, and the heat medium in the pipe 14 is Heating, at this point, is the same as that of the induction heating device 101 1 of the first embodiment. Further, at the induction heating device 1032 at -50 to 201200729, by the rotation of the rotating body 11, the distance between the convex portion of the rotating body 11 and the protruding portion 121 of the stator portion 12 becomes narrow-large or large - Narrow, the magnetic flux flowing at the protrusion 1 21 changes (refer to Figs. 22(A), (B)). As a result, in the heating portion 13 around the protrusion 121, induced electric power (reverse power) is generated, and a current flows, whereby the heating unit 13 is heated, and the heat medium in the pipe 14 is generated. It is heated. In this manner, at the induction heating device 1 032, when the induced electric power is generated, the conductive material of the heating portion 13 existing around the projection portion 121 is formed with a loop around the projection portion 121. Since the current path is different, the heat medium can be heated by the induced electric power differently from the induction heating device 1 0 3 1 of the first embodiment. Further, since the stator portion 12 (including the protrusion portion 1 2 1 ) is formed of a magnetic material, a magnetic flux flows in the stator portion 12. On the other hand, when the convex portions 111a and 1Ub and the respective protruding portions 121 face each other, the magnetic flux flowing out from the convex portion 1 1 1 a of the N pole flows to the protruding portion 121 opposite to the convex portion 1 1 1 a . At the same time, the cylindrical portion passing through the stator portion 12 flows to the projection portion 121 opposed to the convex portion 111b of the S pole (the dotted arrow in Fig. 21(B) is a schematic view showing the flow of the magnetic flux). That is, since the magnetic path is formed from the convex portion 111a of the N pole and passes through the stator portion 12 and reaches the convex portion 1 1 1 b of the S pole, "flows to the respective projections 1 2 1 The magnetic flux system becomes larger. In the induction heating device 203 of the second embodiment, the shape of the projection portion 121 at the stator portion 12 is cut in the direction orthogonal to the protruding direction -51 - 201200729. The case where the cross section is a substantially rectangular quadrangular prism is described as an example, but is not limited thereto. For example, as shown in Fig. 23, the projection portion 121 of the stator portion 12 can be formed in a skew structure which is inclined with respect to the axial direction of the stator portion 12. By using the skew structure, the cogging torque can be reduced, and the rotation of the rotating body 11 can be made smooth. Further, the convex portion (Fig. 21, Fig. 22) of the rotating body 11 may be a skew structure. In the induction heating devices 1031 and 1032 of the first and second embodiments, the case where the flow path is formed inside the heating unit 13 and the heating unit 13 and the pipe 14 are integrally formed is taken as an example. Although the description has been made, the heating portion 13 and the pipe 14 may be formed independently of each other. In this case, it is desirable to form the piping also by a conductive material. By forming the pipe through a conductive material, the pipe can be used as a heating portion. Further, the heating unit and the piping may be independent individuals, and the piping may be provided on the surface of the heating unit. Here, when the pipe is formed of a conductive material and the pipe is used as the heating portion, for example, only the pipe may be disposed, or the pipe may be provided on the surface of the cylindrical support table. Piping is installed. At this time, the cylindrical support table can also be formed by a material other than the conductive material. When the piping is formed of a conductive material and only the piping is disposed, it may be configured as generally described with reference to Fig. 9 in the induction heating device of the first aspect described above. Further, when the stator portion is provided with the protruding portion, for example, as shown in FIG. 1 52-52-201200729 described in the above-described first embodiment of the induction heating device, the protrusion portion 121 may be used. On the outer circumference, a pipe made of a conductive material is wound and mounted. In this case, the connection between the winding start portion of the pipe 14 and the end portion of the winding end portion is electrically connected to each other by the connection conductor 'via the change in the magnetic flux flowing at the protrusion portion 121' in the pipe In the first stage, induced electric power is generated, and a current flows in the pipe 14 , whereby the pipe 14 is heated, and the heat medium in the pipe 14 is heated. In the induction heating device according to the third aspect described above, since the coil is used in the magnetic field generating means, a strong magnetic field can be generated as compared with the prior art device using the permanent magnet. In particular, by using a superconducting coil, it is possible to suppress the heat generation of the coil due to the flow of a large current, and it is also possible to generate a stronger magnetic field. In addition, by the structure in which the heating unit (pipe) is not rotated, for example, in the connection between the supply pipe and the pipe which is connected to the pipe and supplies and discharges the heat medium from the outside, It is necessary to use a rotary joint that allows the rotation of the pipe, and a strong connection can be realized with a simple configuration. [Fourth embodiment] (Example 1) Figs. 24 to 28 are views for explaining the induction heating device of the fourth aspect. The induction heating device 104 1 of the first embodiment shown in Figs. 24 and 25 is provided with a rotating body 1 1 , a stator portion 12 , a heating portion 13 , a coil 15 , and a pipe. 1 4, and the insulation part 18. Hereinafter, the configuration of the induction heating device 104 1 will be described in detail. The rotator 11 is provided with a rotatably supported rotating shaft 2 1, -53 - 201200729, and the plurality of convex portions 111 are integrally formed in the radial direction on the outer peripheral surface. In this example, eight convex portions 1 1 1 are provided at equal intervals in the circumferential direction. The rotating body 1 1 also includes a convex portion 11 1 formed of a magnetic material, and in this example, a laminated steel plate in which a bismuth steel plate is laminated in the direction of the rotating axis is formed. It. In addition to this, a powder magnetic core in which an insulating coating is applied to the surface of a magnetic powder such as iron powder and the powder is subjected to press forming may be used. In addition, the rotating body 1 1 is rotated in the counterclockwise direction when viewed from the side of the rotating shaft (the arrow in Fig. 25(A) represents the direction of rotation). The stator portion 12 is a tubular member that is disposed at a peripheral side of the rotating body U and is spaced apart from the rotating body 11 by a predetermined interval. In this example, the stator portion 12 is Cylindrical. The stator portion 12 is made of a magnetic material and is fixed so as not to rotate. The heating unit 13 is disposed between the rotating body 1 1 and the stator portion 1 2, and is formed in a cylindrical shape in this example. The heating portion 13 is made of a conductive material, for example, made of aluminum. Further, the heating portion 13 is attached to the inner peripheral surface of the stator portion 12 without rotating. At the heating unit 13, a pipe 1 4 through which a heat medium flows is provided (refer to Fig. 25 (A)). In this example, a plurality of insertion holes extending in the axial direction are formed inside the heating portion 13 and the pipes 14 are inserted into the respective insertion holes. Further, the heating portion 13 and the piping 14 are thermally connected. In addition, for example, in the example, the heat medium is supplied from one end side of the pipe I4 and discharged from the other end side, or the one end side of the pipe 14 is provided. A connecting pipe connecting the pipe 14 and the other pipes 14 - 54 - 201200729 is attached, and is supplied from the other end side of the pipe 14 and is formed from the other end side of the other pipe 14 through the connecting pipe. In other words, in the case of the former, the unidirectional flow path is a reciprocating flow path, and the heating distance of the heat medium can be further increased as compared with the case of the former. The coil 15 is generated from the convex portion 1 1 1 and passes through the heating portion 13 . In this example, the coil 15 is attached to a support post portion to be described later, and is disposed at a position shifted from the center of the rotary body 11 with respect to the rotary body 11. Further, the coil 15 is a constant copper coil, and a DC current, which is not shown, is connected to the coil 15. The magnetic field generated by determining the direction of the direct current applied to the coil 15 is determined. The direction of the (magnetic flux) is such that one end side (the side of the rotating body 1 1) becomes the N pole, and the other side becomes the S pole. In the example of the columnar member in which the support column portion 16 is disposed such that one end side thereof faces the one end side of the rotation, it is attached to the back surface of the rotating body 1 1 (the one end side thereof) In the middle of the play hole 1 1 5, one end portion of the portion 16 is fitted (refer to FIG. 25(B)). The column portion is not particularly limited, and examples thereof include a cylindrical column shape, a polygonal column shape, and a polygonal column shape. In this example, the columnar shape is used. Further, the support column portion 16 can be either a magnetic material or a non-material, and in this example, it is formed of a magnetic material. When the coil 15 is a constant electric wire, the source of the electric conduction is at the magnetic flux 16 of the latter by the heat medium of the magnetic material. In the control, the coil 1 5 is at the side of the body 11 . At the center, the column 16 is supported by a cylindrical shape, which is made of a magnetic material. For example, the material is shaped to be 55-201200729. The support column portion 16 is ideal. On the other hand, when the coil 15 is a superconducting coil, since the generated magnetic field is limited by the saturation magnetic flux of the supporting column portion 16, it is also possible to use a non-magnetic material. It is preferable to form the support column portion 16. Further, the induction heating device 104 1 is made of a magnetic material, and has a yoke portion 17 that magnetically connects the stator portion 12 and the other end side of the support column portion 16. In this example, the yoke portion 17 is provided with a plurality of yoke pieces 171 which are connected to the stator portion 12 at one end side and are arranged in the circumferential direction so as to cover the outer circumferential side of the coil 15, And a base plate 172 which is connected to the other end side of each of the yoke pieces 171. On the other end side of the support post portion 16 to which the coil 15 is attached, the base plate 172 is connected, whereby the stator portion 12 and the support post portion 1 can be transmitted through the yoke portion 17. The other end side of the 6 is magnetically connected. In this example, the yoke portion 17 is formed by using a plurality of yoke pieces 171. However, it is also possible to use one yoke having a substantially cylindrical shape which is continuous in the circumferential direction. The heat insulating portion 18 is disposed so as to cover the outer circumference of the stator portion 12, and in this example, the entire induction heating device 1041 is disposed. However, the heat insulating portion 18 is provided with an opening portion at a position corresponding to the rotating shaft 21 or the pipe 14 . The heat insulating portion 18 is formed, for example, by using a heat insulating material such as asbestos, glass asbestos, foamed plastic, red brick, or ceramic. The induction heating device 1041 described above is basically the same as the induction heating device 1 〇1 1 of the first embodiment of the first aspect described above, and the mechanism for heating the heat medium in the device is It is also the same. In particular, in the induction heating device 1041, a magnetic field is generated by energizing the coil l5, and is formed from one end side of the support column portion 16 through the rotating body 11, the convex portion 111, and the stator. The portion 12, the yoke portion 17 (the yoke piece 731 and the base plate 1 72) reach the magnetic circuit of the other end side of the support column portion 16 (the dotted arrow in Fig. 25 (B) is for the flow of the magnetic flux The schematic diagram is shown). That is, a magnetic flux is generated between the convex portion 111 and the stator portion 12, and a magnetic flux is generated from the convex portion 111 through the heating portion 13. Here, at the point a of the heating portion 13 of Fig. 25(A), since the magnetic gap between the convex portion 1 1 1 - the stator portion 1 2 is small, the magnetic flux passing through the heating portion 13 is increased. On the other hand, at the point b of the heating portion 13 of Fig. 25 (A), since the convex portion 11 1 is not present, the magnetic gap is increased, and the magnetic flux passing through the heating portion 13 is reduced. As a result, the magnetic flux passing through the entire circumference of the heating portion 1 23 is changed by the rotation of the rotating body 1 1 , and the strength of the magnetic field at this portion is periodically changed, whereby the heating portion 13 is An induced current (eddy current) is generated, and the heating unit 13 is inductively heated, and the heat medium in the pipe 14 is heated. Figure 26 is a diagram showing the temporal variation of the temporal change of the magnetic field at point a of Figure 25 (A). In the magnetic field, when the magnetic gap between the convex portion and the yoke portion becomes the narrowest, it becomes extremely large and maximizes. On the other hand, when the magnetic gap between the convex portion and the yoke portion is the largest, it is extremely small and minimized. Since the induction heating device 1041 described above uses a coil in the magnetic field generating means, it is possible to stably generate a strong magnetic field as compared with the case where a permanent magnet is used. In addition, since the heat insulating portion is disposed at the outer periphery of the sub-section of the fixed-57-201200729, the heat insulating material covering the periphery of the heating portion can be omitted or thinned, and the convex portion and the heating portion can be provided. The magnetic gap between them is reduced, and a larger sectional area of the heating portion can be obtained. In addition, by the structure in which the heating unit (pipe) is not rotated, for example, in the connection between the supply pipe and the pipe which is connected to the pipe and supplies and discharges the heat medium from the outside, It is necessary to use a rotary joint that allows the rotation of the pipe, and a strong connection can be realized with a simple configuration. Fig. 27 is a schematic side cross-sectional view showing a state in which a heat insulating portion is disposed only around the heating portion in the above-described induction heating device 1041. In the induction heating device 1 040 shown in Fig. 27, the heat insulating portion 180 is provided with a thickness that does not allow heat to escape from the heating portion 13, and for example, the thickness of the heat insulating portion 180 is about 50 mm. Therefore, the magnetic gap between the convex portion 111 and the heating portion 13 becomes large, and the total magnetic flux passing through the heating portion is reduced. Further, the sectional area of the heating portion 13 which contributes to induction heating is also small. On the other hand, for example, in the induction heating device 104 1 of the fourth aspect shown in FIG. 25(B), the heat insulating portion 18 is disposed at least on the outer circumference of the stator portion 1 2, and can be used for the slave device. The heat release is suppressed, and the heat insulating material covering the periphery of the heating portion can be omitted or made thinner. For example, when a heat insulating material is disposed around the heating portion 13, the thickness of the heat insulating material can be set to 5 mm or less. Therefore, the magnetic gap between the convex portion 1 1 1 and the heating portion 13 is reduced, and the total magnetic flux passing through the heating portion 13 can be increased. Further, since a larger cross-sectional area of the heating portion 13 can be obtained, it is possible to reduce the size and weight of the device. In this example, the induction heating device 1 0 4 1 in which the heat insulating portion is disposed in the same device as the induction heating device 1011 of the first embodiment -58-201200729 is used as an example. For example, in the induction heating device according to the second or third aspect described above, the above-described heat insulating portion may be disposed. By arranging the heat insulating portion so as to cover the outer circumference of the stator portion, the same operational effects can be obtained. Further, in the above-described induction heating device 1 〇 4 1 , the case where the coil 15 is a constant conducting coil has been described as an example. However, the coil 15 may be a superconducting wire 圏. When a superconducting coil is used, a stronger magnetic field can be generated. Further, as in the above, in the induction heating device 1041, since the magnetic gap between the convex portion 1 1 1 and the heating portion 13 can be reduced, even in the case of a constant current wire, A sufficient magnetic field for heating the heating portion can be obtained. In addition, in the induction heating device 1041, the number of the convex portions 111 and the width of the convex portion 111 in the circumferential direction of the rotary body 11 can be suitably set. Here, by increasing the number of the convex portions 111 to some extent, the period of the magnetic field can be shortened. Since the induction heating energy is proportional to the frequency of the magnetic field, the heating efficiency can be improved by shortening the period of the magnetic field. Further, by narrowing the width of the convex portion 11 1 to some extent, the magnetic flux flowing from the convex portion 11 to the stator portion 12 is concentrated, and the magnetic force between the convex portion 11 and the stator portion 12 is concentrated. The amount of magnetic flux that passes through the heating portion 13 corresponding to the narrow gap is increased. As a result, the amplitude of the magnetic field applied to the heating portion 13 becomes large, and the heating efficiency can be improved. In the induction heating device 1 〇 4 1 , since the heat insulating material covering the periphery of the heating portion 13 - 59 - 201200729 can be omitted or thinned, the heat of the heating portion 13 is easily conducted to the rotating body 11 . Or it is a member of the stator part 12, etc. Therefore, the heat medium supply side of the pipe 14 provided in the heating unit 13 can be extended so as to be heated from the stator portion 12, for example, so that the stator portion 12 can be cooled and can be The heat generated is effectively utilized. Further, in the coil 15, since the constant conducting coil is used, the coil 15 generates heat by energization. Therefore, by providing the heat medium supply side of the pipe 14 provided in the heating unit 13 so as to be able to be heated from the coil 15 for example, the coil 15 can be cooled and can be obtained. Effective use of heat. (Variation 1-1) In the above-described induction heating device 1041, as shown in Fig. 28(A), the heat insulating portion 18 a may be interposed on the middle of the rotating shaft 2 1 . According to this configuration, it is possible to prevent the heat of the heating unit 13 from being dissipated from the rotating shaft 21 via the rotating body 1 1 and to further reduce the heat generation generated from the device. (Variation 1-2) In the above-described induction heating device 〇41, as shown in Fig. 28(B), the coil 15 can be protected from the heat of the heating portion 13 as shown in Fig. 28(B). The influence of the heat-resistant part 19. The heat-resistant portion 19 is formed by the above-mentioned heat insulating material. According to this configuration, it is possible to prevent the temperature rise of the coil I5 caused by the heating of the heating unit 13, and it is possible to prevent the coil 15 from being received from the heating unit 13 by -60 to 201200729. Heat impact. Further, for example, in the induction heating device according to the second or third aspect described above, the heat-resistant portion may be disposed. <Power Generation System> Next, an example of the overall configuration of the power generation system of the present invention will be described with reference to Fig. 29 . The power generation system P shown in Fig. 29 includes an induction heating device 1 and a wind turbine 20, a heat accumulator 50, and a power generation unit 60. The windmill 20 is attached to the short ridge 92 provided at the upper portion of the tower 91, and the induction heating device 10 is housed in the nacelle 92. Further, in the building 93 built in the lower portion (base) of the tower 91, a heat accumulator 5 and a power generating unit 60 are provided. Hereinafter, the configuration of the power generation system P will be described in detail. The induction heating device 1 is configured to convert rotational energy (mechanical energy) into thermal energy by induction heating, and to heat the thermal medium. For example, one of the first to fourth aspects described above may be used. Induction heating device. Further, on the other end side of the rotating shaft 21, a windmill 20 to be described later is directly coupled, and the wind power is utilized as a power for rotating the rotating body. In addition, here, the case where the heat medium is water is taken as an example. The windmill 20 has a structure in which three blades 201 are radially attached to the rotating shaft 21 with the rotating shaft 2 1 extending in the horizontal direction as a center. In the case of a wind power generation system exceeding 5 MW, the diameter is 120 m or more, and the number of rotations is about 1 Torr to 20 rpm. At the piping of the induction heating device 1 ,, a water supply pipe 73 that supplies water to the induction heating device 1 is connected, and water heated by the induction heating device 10 - 61 - 201200729 is sent to The delivery pipe 51 at the heat accumulator 50. Further, the induction heating device 1 is configured to energize the coil by energizing the coil and rotating the rotating body to change the magnetic flux passing through the heating portion disposed between the rotating body and the stator portion, thereby heating the portion Induction heating is performed and the water in the piping is heated. Since the induction heating device 1 使用 uses a wire 在 at the magnetic field generating means, it is possible to generate a strong magnetic field and to heat the water as a heat medium to a high temperature of, for example, 100 ° C to 600 ° C. Further, since the induction heating device 10 has a structure in which the heating portion (pipe) is not rotated, it is not necessary to use a rotary joint in the connection between the pipe and the conveying pipe 51 and the water supply pipe 73. It is possible to achieve a firm connection with a simple configuration using, for example, welding. The power generation system p heats the water to a temperature suitable for power generation by the induction heating device 1 (for example, 20 (TC~3 50 °c), and generates high temperature and high pressure water. The high temperature and high pressure water is heated by induction. The device 1 and the heat accumulator 50 are connected to the transfer pipe 51, and are sent to the heat accumulator 50. The heat accumulator 50 stores the heat of the high-temperature and high-pressure water sent through the transfer pipe 51, and uses heat. The exchanger supplies steam required for power generation to the power generation unit 60. Alternatively, steam may be generated by the induction heating device 1 。. As the heat accumulator 50, for example, a vapor accumulator may be used. Alternatively, a sensible heat accumulator having a molten salt or oil, or a latent heat accumulator having a phase change having a melting point of a high melting point may be used. The latent heat type is stored by a heat storage material. Since the heat storage is performed at a phase change temperature, in general, the heat storage temperature range is a narrow band and the heat storage density is higher than that of a sensible heat storage type. -62- 201200729 Power generation unit 60 is Will steam turbine 6 1 and the construction, and The turbine 61 is supplied from the heat accumulator 50 to rotate, and the generator 62 is driven to generate electricity. The high-temperature high-pressure water or the regenerator 71 sent to the heat accumulator 50 is cooled and returned to water. Thereafter, The high-pressure water is sent to the water supply pipe 73, and is circulated by the water supply pipe 73. According to the power generation system P, the regenerative power is used as the power to obtain the rotational energy, and the heat regenerator is generated and generated. Thus, even if it is not, the power generation corresponding to the stability of the demand can be realized as the wind power generation system of the prior art is generally designed to avoid problems caused by the gear box. Further, it is supplied to, for example, a power generation unit provided in the tower via a duct, and it is not necessary to accommodate a small compartment that is placed in the upper portion of the tower in the nacelle, and to reduce the size and weight. In the above-described power generation system, although the case of heat is taken as an example, a liquid metal having a higher rate may be used as a heat medium. For example, liquid metal sodium can be cited. When the liquid is used, for example, it may be set to use liquid metal in a heat medium that receives heat, and transport the heat of the liquid metal to heat through heat exchange (water), and to generate steam. . The generator 62 combines the vapors to cause the vapor vortex to be vapor, which is sent to the induction heating device 10 at the pump 72 to generate energy (e.g., wind, which is then stored in a high-priced battery. Further, it is not necessary to provide a speed increaser, and by using an electric portion in a hot portion (base) of the heat medium, it is possible to use a water phase in the medium to be thermally conductive as water. The metal body metal is used as a heat medium for receiving the secondary heat medium from the heating portion by means of a conveying pipe - 63 - 201200729, and, for example, an oil having a boiling point of more than 1 〇〇 ° C under normal pressure. When a liquid metal, a molten salt, or the like is used as a heat medium, it is easier to vaporize the heat medium in the pipe when heated to a specific temperature (more than 1 〇〇 ° C) compared to water. The internal pressure rise caused by the suppression is suppressed. (Trial Example 1) Using the general simulation model 3000 as illustrated in Fig. 30, the case where the superconducting wire turns are used in the coil 3 200 and the case where the copper coil is used is used. Time will be initial The total cost of the sum of the operating costs is used as a trial calculation. The simulation model 3 000 is a structure in which a coil 3200 is mounted on a C-shaped iron core 3 100 having a magnetic gap. The core 3100 has a section of 400 mm x 500 mm. The clearance distance is l〇〇mm. The cost is calculated according to the following conditions: The operation time is set to 4800 hours per year (200 days x 24 hours), and the electricity fee is set to 1 kW/hour. 5 circle. In addition, considering the power consumption of the coil, and when using the superconducting coil, the operating power of the cooling system is also considered. When the copper coil is used, the water cooling method and air cooling are performed. Two types of methods, and in the water cooling mode, also consider the operating power of the water cooling system. At the coil, it is set to flow in the magnetic gap. The current produced by the 1T magnetic field. In Figure 31, the trial results for the total cost are shown. In Figure 31, 'the total cost of the superconducting coil is indicated by the solid line, and the total cost of the water-cooled copper wire 圏 (water-cooled copper wire 圏) is indicated by a dotted line, and the air-cooled-64-201200729 copper coil is used. The total cost of the (air-cooled copper coil) is indicated by a dotted line. From this result, it can be seen that when the superconducting coil is used, the initial cost of the copper coil is higher than that of the water-cooling direction, but since the power consumption is small, the operating cost is changed. Low, and after three years of operation, the total cost will be reversed. In other words, in the magnetic field generating means of the induction heating device of the power generation system of the present invention, when the superconducting wire is used, the unit effect with respect to the cost is higher, and the power generation cost can be suppressed. Next, under the above conditions, the case where the superconducting wire 使用 was used in the coil 3 200 of the simulation model 3 000 of Fig. 30 and the coil weight when the copper coil was used were used for trial calculation. However, in the case of the copper coil of the water-cooling method, the current density is calculated as 10 A/mm2, and in the case of the copper coil of the air-cooling method, the current density is calculated as 1 A/mm2, and in the superconductance. In the case of a coil, the weight of the cooling system is also taken into account. In the case of a water-cooled copper coil, the weight of the water-cooling system is also taken into consideration. After the trial of the coil weight, the weight of the superconducting coil was 200 kg, the weight of the copper coil of the water-cooling method was 200 kg, and the weight of the copper coil of the air-cooling method was 2000 kg. As a result, it can be seen that when the copper coil of the air-cooling method is used, when the superconducting coil is used, it is possible to further reduce the size and weight. In the case of using the superconducting coil in the magnetic field generating means of the induction heating device of the power generation system of the present invention, it is possible to further reduce the size and weight of the induction heating device, and it is easy to arrange, for example, In the nacelle. Further, when -65-201200729 is used in the magnetic field generating means of the induction heating device, in order to enhance the magnetic field, the core is required, and in order to suppress the saturation of the magnetic flux of the iron core, it is necessary to suppress the magnetic flux saturation of the iron core. Since the size of the iron core is increased, the size and weight of the induction heating device cannot be avoided as compared with the superconducting coil. In addition, recently, the influence of low-frequency noise generated by the rotation of the windmill on the human body has become a problem. The measures for reducing the low-frequency noise generated by the windmill are not only reported in China but also overseas, and it is known that low-frequency noise can be suppressed by rotating the windmill at a low speed. In the heating mechanism of the induction heating device of the power generation system of the present invention, if the rotating body is rotated at a low speed, the amount of heat energy that can be obtained is reduced, but the superconducting coil is used in the magnetic field generating means of the induction heating device. Since a strong magnetic field can be generated, sufficient heat energy can be obtained even at low speed rotation. The present invention is not limited to the above-described embodiments, and may be modified as appropriate without departing from the gist of the present invention. For example, the shape of the rotating body or the stator portion may be appropriately changed, or the material for forming the rotating body and the stator portion may be appropriately changed. [Industrial Applicability] The power generation system of the present invention can be applied to the field of power generation using renewable energy.
