Description

  The present invention relates to a hybrid power generation element including a plurality of power generation means, a power supply device using the hybrid power generation element, and a method for installing the hybrid power generation element in a ubiquitous power supply that does not require power reception from a battery or an outlet.

  The use of new energy that does not depend on thermal power generation for the purpose of reducing the consumption of finite fossil fuels and reducing carbon dioxide emissions is progressing.

  On the other hand, research and commercialization of a distributed power generation system that generates power in the vicinity of the field of energy consumption in response to the reduction of power transmission loss and the ubiquitous information society are underway.

  In such a movement, power generation using sunlight, wind power, etc. has already been put into practical use at a scale of kW order or more, but can be seen in the ubiquitous sensor network concept (see e-Japan priority plan 2002, for example). As described above, in applications where small sensors are dispersed and environmental monitoring is performed, in order to obtain energy for operating the sensor at the site where the sensor is installed, the power generation amount is W order, mW order, or even lower. Research on power generation elements is underway.

  The main methods of power generation required for these ubiquitous sensor networks are temperature difference power generation using thermoelectric elements using the thermoelectric effect (Seebeck effect), photovoltaic power generation using solar cells, and vibration / impact using piezoelectric effects. There are various power generation mechanisms using natural energy and kinetic energy such as power generation (see Non-Patent Document 1, for example).

Specifically, an IC card (for example, see Patent Document 1) incorporating a thermal battery using temperature difference power generation or an electromagnetic wave generator radiates in a business activity space such as a predetermined room and is used in that space. There is a batteryless and cordless wireless power supply system that receives an electromagnetic wave radiated from each device by receiving a radio wave and converts the received electromagnetic wave into electric power (see, for example, Patent Document 2).

  Embodiments of the present invention will be described below with reference to the drawings.

  Embodiments according to the present invention will be described with reference to the drawings. Fig.1 (a) is a figure explaining the principle of the electric power generation of the hybrid electric power generation element 10 of this invention, and its structure. The plus leg 1 formed in a circular arc shape indicated by a solid line and the minus leg 2 indicated by a broken line are made of different metal wires that generate a thermoelectric effect (Seebeck effect).

  For example, as shown in FIG. 1 (b), a Type-T thermocouple with a plus leg 1 made of copper (Cu) and a minus leg 2 made of constantan (Cu 55%, Ni 45%) is used. It may be a combination with the Bi · Te system.

  As shown in FIG.1 (c), a connection point is joined by welding, the temperature of one connection point is T1 degreeC, the temperature of the other connection point is T2 degreeC, and the pair set in the state of T1> T2. The thermocouple is configured.

  As shown in FIG. 1 (a), such a pair of thermocouples are connected in series with 10 arcuate plus legs 1 and minus legs 2 alternately, and are formed in a coil shape facing each other. Configure the coil.

  And the both ends of the hot contact part 3 of the ten connection points on the high temperature side and the nine low temperature contact parts 4 on the low temperature side become the positive output electrode 5 and the negative output electrode 6, respectively.

  The positive output electrode 5 and the negative output electrode 6 are connected to the positive terminal 7 and the negative terminal 8 by conducting wires, respectively, and the power generation output of the hybrid power generation element 10 is taken out between the terminal 7 and the terminal 8.

  Next, the operation of the hybrid power generation element 10 will be described again with reference to FIG.

When the temperature of the portion where the hot junction portion 3 exists is T1, and the temperature 2 of the portion where the cold junction portion 4 exists is T2, in the element portion shown in FIG. the material of 1 and minus legs 2, and the thermal electromotive force V ₁₂ by the Seebeck effect is determined by the temperature difference between the temperature T1 and the temperature T2 is generated.

1 Figure thermoelectric element pairs are N content of (c), since here 10 are connected in series, when the thermoelectromotive force based on T1, T2 and V _12, thermoelectromotive between the time of the terminal The power V _TC is as follows.
V _TC = N × V ₁₂ (1)
Although the thermocouples are illustrated as 10 sets, the thermocouple pairs are determined based on the optimum logarithm and the number of thermocouples based on the conditions of the power generation environment of the electromotive force required for the hybrid power generation element 10 and the set temperature and magnetic field. The shape is preset.

  For example, when the installation environment that gives the temperature difference of power generation is a relatively small temperature difference, it is necessary to connect about 2500 thermocouples in order to obtain an output of a volt order, for example, assuming 3 ° C.

  That is, when 2500 Type / T thermocouples are used, an output voltage of about 0.3 V is obtained when the cold junction is 0 ° C. and the hot junction is 3 ° C.

  On the other hand, a magnetic flux component intersecting with the hybrid power generation element 10 as shown by a one-dot broken line in FIG.

When this magnetic flux is Δφ, the induced electromotive force V ₁ accompanying the change of the cross magnetic flux is as follows.
V _I = −N × (Δφ / Δt) (2)

From the above, the generated electromotive force V obtained between the terminal 7 and the terminal 8 obtained in the configuration shown in FIG.
V = V _TC + V _I
= N × V ₁₂ −N × (Δφ / Δt) (3)

  Here, in order to obtain a large generated electromotive force V, not only the number N of thermocouples corresponding to the number of turns of the coil is increased, but also the magnetic flux φ is proportional to the crossing area. It is necessary to set so that the cross-sectional shape of the thermocouple that intersects the power generation element 10 becomes large.

In addition, since the temporal change in temperature is generally slow, the first term in equation (3) is a direct current component, while the second term is generally an alternating current component, and the generator power V is the thermoelectromotive force. and V _TC and induced electromotive force V ₁ is the output of the waveform shown in FIG. 2, which is synthesized.

Thus, from two different power generation energy sources of temperature difference and magnetic field change, the sum of the thermoelectromotive force V _TC and the induced electromotive force V ₁ is output by the single coil-shaped component, that is, the hybrid power generation element 10 as the output voltage. Can be taken out at the same time.

  Next, a method for manufacturing the hybrid power generation element 10 will be described with reference to FIGS. 3 and 4. FIG. 3 is an exploded perspective view for explaining the assembly of the hybrid power generation element 10a, and FIG. 4 shows the structure of a thermocouple as a component thereof.

  The hybrid power generation element 10a includes a plus leg flexible printed circuit board 11, a minus leg flexible printed circuit board 12, reinforcing plates 15 to 18 disposed at both ends of each flexible printed circuit board, and a hot contact portion of each flexible printed circuit board. An anisotropic conductive rubber 19 and an anisotropic conductive rubber 20 for joining the cold junction part.

  Further, a plus leg conductor 21 and a minus leg conductor 22 are connected to both ends of the joint portion of each flexible printed circuit board, and output is taken out from both ends.

  Next, a manufacturing method of the hybrid power generation element 10 will be described. On the plus leg flexible printed circuit board 11, as shown in FIG. 4 (a), a predetermined number of copper foil patterns 13 forming one of the thermocouples are formed long in parallel, and reinforcing plates 15 and reinforcing plates are formed at both ends thereof. 17 is adhered.

  Further, as shown in FIG. 4C, a constantan (Cu 55%, Ni 45% alloy) pattern 14 that forms the other of the thermocouples is formed on the minus leg flexible pattern substrate 12 in parallel and in a predetermined number. The reinforcing plate 16 and the reinforcing plate 18 are bonded to both ends.

  And, as shown in FIG. 4 (a), both ends of the two flexible printed boards are opposed to each other, and as shown in FIG. 4 (a), the anisotropic conductive rubber 19 is connected to the reinforcing plate 15 and the reinforcing plate. 16 and sandwiched by pressure from both sides.

  Similarly, the other end is pressed from both sides with the anisotropic conductive rubber 20 sandwiched between the reinforcing plate 17 and the reinforcing plate 18.

  At this time, circular land patterns 13a and land patterns 14a are formed on both ends of each flexible printed circuit board as shown in FIG. 4, and the positions of the land patterns 13a and land patterns 14a are up and down. Since they are shifted by a half pitch, the bending directions of the end portions of the copper foil pattern 13 of the plus leg flexible printed circuit board 11 and the constantan pattern 14 of the minus leg flexible printed circuit board 12 are reversed so that the opposing land The anisotropic conductive rubber 19 and the anisotropic conductive rubber 20 are in pressure contact with each other via the reinforcing plate 15 to the reinforcing plate 18.

  As a result, all the patterns on the flexible printed circuit boards 11 and 12 are electrically connected in series, and the space between the flexible printed circuit board 11 and the flexible printed circuit board 12 is shown in FIG. In this way, the hybrid power generation element 10a similar to that shown in FIG.

  Next, the power supply unit 30 of the power supply apparatus 100 using the hybrid power generation element 10 manufactured as described above will be described with reference to FIG.

  The power supply device 100 using the hybrid power generation element 10 includes the hybrid power generation element 10 and its power supply unit 30.

  The power supply unit 30 includes two systems: a first power supply system that processes a thermoelectromotive force due to a temperature difference, and a second power supply system that processes an induced electromotive force generated by a magnetic flux change.

  The first power supply system includes a first smoothing circuit 31 that smoothes the output of the hybrid power generation element 10, a booster circuit 34a that boosts the output of the smoothing circuit 31 to a predetermined voltage, and a capacitor 1 that uses the output of the booster circuit 34a. It consists of a charging circuit 35 for charging and a capacitor 1.

  The second power supply system includes a rectifier circuit 32 that rectifies the difference between the output of the hybrid power generation element 10 and the output of the first smoothing circuit 31, and a second smoothing circuit 33 that smoothes the output of the rectifier circuit 32. And a booster circuit 34 for boosting the output of the second smoothing circuit 33 to a predetermined voltage, a charging circuit 35 for charging the capacitor 2 with the output of the booster circuit 34, and the capacitor 2.

  Further, the outputs of the capacitor 1 and the capacitor 2 are the bipolar switch 37 for selecting only one of them, the charge control circuit 38 for charging the lithium ion battery 39 with the output of the selected bipolar switch 37, and the lithium ion A battery 39;

  And operation | movement of the power supply part 30 comprised in this way is demonstrated. When the thermoelectromotive force due to the temperature difference is larger than the induced electromotive force due to the magnetic flux change, the capacitor 1 is charged by the first power supply system. When the induced electromotive force due to the magnetic flux change is larger than the thermoelectromotive force due to the temperature difference, the capacitor 2 is charged by the second power supply system.

  Normally, only one of the outputs of the capacitor 1 and the capacitor 2 is connected to the charge control circuit 38 via the bipolar switch 37, and the charge control circuit 38 charges the lithium ion battery 39.

  The output of the lithium ion battery 39 is connected to a power supply target device 40 such as a portable device or a ubiquitous sensor. At the same time, it is also connected to the charge control circuit 39 and serves as its own power source.

  Then, the charge control circuit 38 periodically switches the bipolar changeover switch 37 and charges the lithium ion battery 39 if at least one of the capacitor 1 and the capacitor 2 has a charge equal to or higher than a predetermined value.

  Then, power is supplied to the power supply target device 40 by the charging energy of the lithium ion battery 39.

  If the state in which the generated electromotive force required for both the temperature difference and the magnetic field change in the space where the hybrid power generation element 10 is provided is not satisfied, both the capacitor 1 and the capacitor 2 are insufficiently charged, and the power required for the power supply target device 40 is increased. It happens that it is not supplied.

  In that case, the charge control circuit 39 switches the bipolar switch 37 to either the capacitor 1 or the capacitor 2, and supplies power after securing a predetermined charge amount with the selected generated energy.

  Note that monitoring means for monitoring the charging current when the charging control circuit 39 is connected to each of the capacitor 1 and the capacitor 2 is provided, and the connection time ratio to the capacitor having the larger charging current, that is, the faster charging speed is increased. By doing so, it can also comprise so that more efficient charge can be performed.

  Further, the power supply unit 30 includes a determination unit that determines the positive / negative potential of the output of the hybrid power generation element 10 and a switching unit that outputs the output voltage of the hybrid power generation element 10 with the same polarity by the output of the determination unit. Can be configured only by the first power supply system described above.

  As described above, according to the present invention, when at least one of different power generation energies such as a temperature difference and a magnetic field change exists, power supply for operating the target power supply target device 40 is continued. It is possible to provide a single hybrid power generation element that converts different power generation energy into electric energy, and a power supply device using the same.

  Next, the installation method of such a hybrid electric power generation element 10 is demonstrated with reference to FIG.

  FIG. 6 shows a method for extracting generated energy from a household AC power cord through which a relatively large current flows, and shows a configuration used as a power adapter 101 connected to various power cords.

  The power adapter 101 includes one connector portion 52 and the other connector portion 53 that are connected to the power cable, and an output terminal portion 56 that extracts the generated electromotive force of the hybrid power generation element 10.

  And one conducting wire 51 and the other conducting wire 51a of the power supply are connected to power supply pins (not shown) of the connector portion 52 and the connector portion 53.

  And it shape | molds so that the rectangular space of a predetermined area may be formed between the conducting wire 51 and the conducting wire 51a, and one plus leg 1 and the other minus leg 2 of the hybrid electric power generation element 10 are adjoined around each conducting wire. And set to run in parallel.

  The plus leg 1 is a copper wire, the minus leg 2 is a constantan wire, the hot junction part 3 is close to the copper wire 51, and the cold junction part 4 is in the vicinity of the surface of the power adapter 101 so as to be sensitive to the atmosphere. The conductor 51 and the conductor 51a are insulated by a heat insulating material 54.

  Then, the connector part 52 and the other connector part 53 of the power adapter 101 are set in a straight line, and the output terminal part 56 for taking out the generated electromotive force is set so that it can be taken out from a different direction from these connector parts. The periphery is molded with an insulator such as resin.

  Alternating current flows in different directions every half cycle through the conductive wire 51 and the conductive wire 52 of the hybrid power generation element 10 configured as described above. For example, when a current flows in the direction indicated by the solid arrow, a magnetic field in the direction indicated by the one-dot broken line is generated around the conductor 51 and the conductor 52.

  Since the direction of current repeats reversal every half cycle in time, the direction of the magnetic field also repeats reversal.

  Therefore, since the magnetic flux intersecting the hybrid power generation element 10 also changes with time, an alternating voltage is induced at both terminals 7 and 8 of the hybrid power generation element 10.

  Further, regarding the temperature difference, the hot junction 3 is set in close contact with the power cord, so the temperature is relatively high, and the cold junction 4 is set on the surface layer of the power adapter 101, so the hot junction The temperature is lower than that of the section 3 and is close to the outside air temperature.

  For this reason, there exists a temperature difference (for example, 5 ° C. or more) between the hot junction part 3 and the cold junction part 4, and the thermoelectromotive force due to this is output to both terminals 7, 8 of the hybrid power generation element 10.

  According to the power adapter 101 installed in this way, a power cable is connected to the front and back, an AC voltage that is an induced electromotive force due to a magnetic field change flowing through the power cable, and a DC voltage that is a thermoelectromotive force due to a temperature difference. Output voltage is generated at the same time, and this output is used to supply power to various portable electronic devices and ubiquitous sensors placed in the vicinity of the power cable via the power supply unit 30 as shown in FIG. I can do it.

  Another installation method of the hybrid power generation element 10 of the present invention will be described as a second embodiment with reference to FIG.

  FIG. 7 is an explanatory diagram of a method for installing the hybrid power generation element 10 when used as a power source for the water meter 61 connected to the metal pipe 62.

  The hybrid power generation element 10 formed into a rectangular coil shape has one hot contact portion 3 (or cold contact portion 4) on the opposite side in close contact with the lower portion of the metal pipe 62 and is installed in parallel. The other cold junction part 4 (or warm junction part 3) is embedded in the ground.

  With such an installation method, although the polarity of the temperature difference of the contact portion changes in summer and winter, a thermoelectromotive force that is not easily affected by the season can be obtained using the temperature difference between the pipe surface and the ground.

  In the case of such an outdoor device, when the amount of charge is insufficient, a mobile charging device that generates a magnetic field that intersects with the hybrid power generation element 10 can be provided so that it can be charged from the outside without contact. (For example, see Japanese Patent Application No. 2005-286016.)

  In addition, as a change in the magnetic field, the hybrid power generation element 10 is obtained by obtaining a crossing magnetic field caused by various induced currents such as induced lightning flowing through the piping, noise generated by electrical equipment, and induced current caused by radio waves transmitted from a broadcasting station or wireless equipment. Since an induced electromotive force can be obtained simultaneously between both terminals, hybrid power generation using a thermoelectromotive force and an induced electromotive force is possible.

  Therefore, it is possible to provide a power source for an electronic water meter that does not require battery replacement.

  In the case of such an outdoor device, when the amount of charge is insufficient, a mobile charging device that generates a magnetic field that intersects with the hybrid power generation element 10 can be provided so that it can be charged from the outside without contact. I can do it.

  Another installation method of the hybrid power generation element 10 of the present invention will be described as a third embodiment with reference to FIG.

  FIG. 8 is an explanatory diagram of an installation method in the case where the building 72 is attached to the window of the resin sash 71 made of a nonconductive material. The hybrid power generation element 10 basically has a rectangular shape that surrounds the opening of the window, but in order to obtain a temperature difference between indoor and outdoor as a temperature difference, one contact can penetrate the resin sash 71 as shown in FIG. ) To project as shown in FIG.

  A cross-sectional view of the resin sash 71 is shown in FIG. In the present installation method, the hot junction 3 that is hot outside in the summer is provided outdoors, but in the winter, the hot junction 3 may be provided indoors and the cold junction 4 may be outdoor.

  With such an installation method, a thermoelectromotive force due to a temperature difference can be obtained, and an induced electromotive force can be obtained by capturing a magnetic field change due to various electromagnetic waves penetrating through the window of the resin sash 71. Power generation by electromotive force becomes possible. Therefore, it is possible to provide a power source for various sensors for home security such as an intrusion detection sensor for crime prevention.

  Another installation method of the hybrid power generation element 10 of the present invention will be described as a fourth embodiment with reference to FIG.

  FIG. 9 is an explanatory diagram of an installation method in the case of mounting around the frame 73 provided in the room. The hybrid power generation element 10 is set so that a temperature difference in the height direction in the room can be easily detected.

  For example, the hot junction 3 is set at the upper part of the frame 73 and the cold junction 4 is set at the lower part of the room below the periphery of the frame 7 edge.

  Usually, when the room air is heated and cooled without being circulated, a temperature difference of about 5 ° C. exists between the vicinity of the ceiling and the floor, and thus a thermoelectromotive force is generated due to this temperature difference.

  In addition, as for the magnetic field change, the magnetic flux change interlinked with the space of the frame 73 will be captured, but one side in the vertical direction of the hybrid power generation element 10 formed into a rectangle is brought close to the power cable in the wall. Since an induced electromotive force similar to 2 can be obtained, it is possible to provide a power source for a monitoring sensor such as a picture provided around this.

  As described above, according to the present invention, if at least one of different power generation energies such as a temperature difference and a magnetic field change exists, power supply for operating the target power supply target device 40 is continued. It is possible to provide a single hybrid power generation element that converts different power generation energy into electric energy, and a power supply device using the same.

  The present invention is not limited to each of the embodiments described above, and the setting position of the hot contact portion and the example contact portion of the hybrid power generation element, the number of points of the contact portion formed in a coil shape, and the shape of the coil Can be appropriately changed so as to conform to the temperature and magnetic energy state of the installed space and the power requirements required from portable electronic devices and ubiquitous sensors.
