The core includes a Peltier element having a heat absorbing surface on one surface and a heat radiating surface on the other surface, and a plurality of tubes. Each tube is provided on the heat dissipation surface of the Peltier element. Each tube has a liquid flow path through which a heat exchange medium made of liquid can flow, and each tube can exchange heat of the heat exchange medium with external air. On the other hand, a cooling load, which is an object to be cooled, is in contact with the heat absorbing surface of the Peltier element.

JP-A-11-121816

  However, according to the knowledge of the inventors, the above-described conventional core cannot transfer heat sufficiently between the heat absorbing surface or heat radiating surface of the Peltier element and the heat exchange medium, and this is used for an air conditioner, for example. However, the room cannot be suitably cooled or heated.

  This invention is made | formed in view of the said conventional situation, Comprising: It is set as the problem which should be solved to provide the air-conditioning core which can air-condition a room | chamber interior suitably.

The air conditioning core of the present invention includes a plurality of Peltier elements,
A first liquid flow path capable of circulating a first heat exchange medium made of liquid inside, a first tube capable of exchanging heat of the first heat exchange medium with external air;
A second liquid flow path capable of circulating a second heat exchange medium made of liquid is formed therein, and a second tube capable of acquiring heat of the second heat exchange medium,
The first tube extends to convect the first heat exchange medium in the first liquid flow path;
Each of the Peltier elements is characterized in that one surface is adjacent to the first tube and the other surface is adjacent to the second tube (Claim 1).

  In the air conditioning core of the present invention, each surface of each Peltier element is adjacent to the first tube, and each other surface of each Peltier element is adjacent to the second tube. The first tube has a first liquid flow path through which a first heat exchange medium made of a liquid can flow, and can exchange heat of the first heat exchange medium with external air. The second tube is formed with a second liquid flow path through which the second heat exchange medium made of liquid can be circulated, and can acquire the heat of the second heat exchange medium. For this reason, in this air conditioning core, heat can move between each surface of each Peltier element and the first heat exchange medium, and also between each other surface of each Peltier element and the second heat exchange medium. Heat can move.

  And in this air conditioning core, the 1st tube is extended so that the 1st heat exchange medium may be convected in the 1st liquid channel. For this reason, due to the convection of the first heat exchange medium, for example, in this air conditioning core, each surface of each Peltier element sufficiently absorbs heat from the first heat exchange medium, so that the first heat exchange medium is sufficiently cooled. The second heat exchange medium is sufficiently heated by the other surfaces of the Peltier elements sufficiently dissipating heat to the second heat exchange medium. In addition, for example, each surface of each Peltier element sufficiently dissipates heat to the first heat exchange medium, so that the first heat exchange medium is sufficiently heated, and each other surface of each Peltier element is sufficiently from the second heat exchange medium. The second heat exchange medium is sufficiently cooled by absorbing heat. For these reasons, in this air conditioning core, it is possible to suitably heat the room by using the heat of the heated first heat exchange medium and second heat exchange medium. Similarly, in this air conditioning core, it is possible to suitably cool the room by using the cooled heat of the first heat exchange medium and the second heat exchange medium.

  Therefore, according to the air conditioning core of the present invention, it is possible to suitably air-condition the room.

  In the air conditioning core of the present invention, indoor air conditioning may be performed by heat or cold of the first heat exchange medium heated or cooled, and indoor air conditioning may be performed by heat or cold of the second heat exchange medium heated or cooled. You can go. Moreover, it is preferable that each Peltier element is comprised so that a heat absorption surface and a heat radiating surface can be switched by the one surface side and the other surface side.

  The first and second heat exchange media in the air conditioning core of the present invention may be the same or different. As the first and second heat exchange media, for example, water, antifreeze, or the like can be employed. This water or the like may be water or the like used exclusively for heat absorption or heat dissipation by the Peltier element. For example, when used in an air conditioner of a vehicle, it may be cooling water or the like of an engine or the like. .

  The second tube is preferably orthogonal to the direction in which the first tube extends (claim 2). In this case, in this air conditioning core, the first heat exchange medium is sufficiently easily convected in the first tube, and heat can sufficiently move between each surface of each Peltier element and the first heat exchange medium. .

  Specifically, when the air conditioning core of the present invention is incorporated in an air conditioner and the first tube extends vertically, the first heat exchange medium convects in the first liquid flow path. In this case, the second tube extends in the horizontal direction.

  Further, the first tube preferably has an annular tube formed in an annular shape (Claim 3), and the first tube has a linear tube communicating with the annular tube at both ends. Preferred (claim 4). In these cases, the first heat exchange medium is more easily convected in the first tube. For this reason, in this air conditioning core, it becomes possible to air-condition a room more suitably.

  The second tube may be composed of an upper second tube and a lower second tube provided below the upper second tube. The first tube includes a downward first tube provided via a Peltier element below the upper second tube, and an upward first tube provided via the Peltier element above the lower second tube. (Claim 5). In this case, in the Peltier element provided below the upper second tube, the upper second tube side is a heat radiating surface and the downward first tube side is a heat absorbing surface. Further, in the Peltier element provided above the lower second tube, the lower second tube side is the heat absorbing surface, and the upward first tube side is the heat radiating surface. By these, the direction of the convection of the 1st heat exchange medium which arises in each in the downward 1st tube and the upward 1st tube becomes along the direction of gravity. For this reason, the convection of the first heat exchange medium is preferably generated in each of the downward first tube and the upward first tube. For this reason, in this air conditioning core, it becomes possible to air-condition a room more suitably.

  In the air conditioning core in this case, it is preferable that the downward first tubes and the upward first tubes are alternately provided in the horizontal direction (Claim 6). In this case, it becomes possible to arrange | position a downward 1st tube and an upward 1st tube efficiently so that said effect is realizable. For this reason, in this air conditioning core, it becomes possible to air-condition the room suitably while downsizing the casing.

  Further, in the air conditioning core in the above case, each Peltier element is configured so that the heat absorption surface and the heat radiation surface can be switched between the one surface side and the other surface side, and between the lower second tube and the downward first tube and the upper portion. It is preferable that a Peltier element is provided between the second tube and the upward first tube. In this case, the Peltier element provided between the lower second tube and the downward first tube can be operated with the lower second tube side as the heat absorption surface and the downward first tube side as the heat dissipation surface during heating. it can. Similarly, the Peltier element provided between the upper second tube and the upward first tube can be operated with the upper second tube side as a heat dissipation surface and the upward first tube side as a heat absorption surface during cooling. . As a result, the amount of heat transferred during heating and cooling can be increased. For this reason, in this air conditioning core, it becomes possible to air-condition the room with higher output.

  In the air conditioning core of the present invention, the second tube, each Peltier element, and the first tube may be configured to be rotatable around an imaginary horizontal axis. In this case, by reversing the second tube, each Peltier element, and the first tube, the direction of the convection of the first heat exchange medium in the first tube during the heating and the cooling is along the direction of gravity. It becomes possible to do. For this reason, even if it is this air-conditioning core, the movement of the heat by a Peltier device will be performed suitably, and it will become possible to air-condition a room more suitably.

  It is preferable that the first tube is provided with a fin capable of contacting external air (claim 9). In this case, the heat or cold of the first heat exchange medium in the first tube can be efficiently released to the air. For this reason, in this air conditioning core, the movement of heat by the Peltier element is more suitably performed. For this reason, in this air conditioning core, it becomes possible to air-condition a room more suitably.

  The radiator 3 is formed with first and second outlets 3a and 3b and first and second inlets 3c and 3d. The radiator 3 is configured so that the cooling water can flow therethrough, and the cooling water is cooled or heated by exchanging heat between the cooling water in the radiator 3 and the air around the radiator 3. Is possible. A radiator fan 3 e is provided in the vicinity of the radiator 3. The radiator fan 3e is electrically connected to the battery 5a.

  As shown in FIG. 1, the first outlet 3 a and the upper inlet 13 a of the radiator 3 are connected by a pipe 21. The first inflow port 3 c and the upper outflow port 13 b of the radiator 3 are connected by a pipe 23.

  The pipe 23 is provided with a first pump P1, and the pipe 27 is provided with a second pump P2. These first and second pumps P1, P2 are electrically connected to the battery 5a, respectively. In addition, the 1st pump P1 may be provided in the piping 21 side shown in FIG. 1, and the 2nd pump P2 may be provided in the piping 25 side.

  The controller 5 controls the strength and direction of power supplied to the Peltier elements 7A to 7F based on the control signals of the temperature sensors 19a to 19f, and the electric pump P1 connected to the controller 5 through the battery 5a Control. The controller 5 can perform control for each of the individual Peltier elements 7A to 7F. The battery 5a functions as a power source for the Peltier elements 7A to 7F and the like. The configurations of the controller 5 and the battery 5a are the same as known ones, and a detailed description regarding the configuration is omitted.

  In the air conditioner configured as described above, the cooling operation or the heating operation is performed as follows.

<Cooling operation>
In the cooling operation, as shown in FIG. 3, the controller 5 operates the first pump P1 and the radiator fan 3e, respectively. In addition, the controller 5 starts supplying power to the Peltier elements 7A to 7C while controlling the direction of the current so that the one surface 70a side of each of the Peltier elements 7A to 7C becomes a heat absorbing surface and the other surface 70b side becomes a heat radiating surface. . Note that power is not supplied to the other Peltier elements 7D to 7F.

  Thereby, in this air conditioner, the cooling water circulates between the air conditioning core 100 and the radiator 3 in the direction of the solid line arrow in FIG. In this state, each other surface 70b of the Peltier elements 7A to 7C radiates heat to the cooling water flowing in the upper second tube 13, and each one surface 70a is directed downward to the water in the first liquid channel 91. To absorb heat.

  In particular, in the air conditioning core 100, each downward first tube 9 extends vertically so that water is convected in the downward first liquid flow path 91, and the upper second tube 13 is orthogonal to the extending direction of each downward first tube 9. is doing. Each downward first tube 9 is composed of an annular tube 90a and straight tubes 90b and 90c, and each surface 70a of each Peltier element 7A to 7C is in contact with each straight tube 90b and 90c. . For this reason, in this air conditioning core 100, water sufficiently convects in each downward first tube 9 in the direction of the broken arrow in the figure, and heat is generated between each surface 70a of each Peltier element 7A to 7C and the water. Is more fully movable.

  More specifically, water in the vicinity of each surface 70a is cooled in each downward first liquid channel 91 by heat absorption by each surface 70a of each Peltier element 7A to 7C. The cooled water has a high specific gravity, and circulates in the downward first liquid channel 91 toward the lower second tube 15, that is, downward along the direction of gravity. On the other hand, the water that has moved away from each surface 70a has a temperature difference with the water in the vicinity of each surface 70a, and its specific gravity is reduced. For this reason, the water in a position far from each one surface 70a circulates so as to rise in the first liquid channel 91 downward toward each one surface 70a. As a result, water convection occurs in the downward first tube 9. And the movement of the heat by each Peltier device 7A-7C will be accelerated | stimulated by this convection of water.

  Thus, in this air conditioning core 100, each surface 70a of each Peltier element 7A to 7C sufficiently absorbs heat from the water, thereby sufficiently cooling the water. For this reason, the air around each fin 17 in the downward first tube 9 is suitably cooled. Then, when the controller 5 operates the air conditioning fan 100a, the cooled air is supplied into the vehicle interior, and the vehicle interior is cooled.

  On the other hand, the other surfaces 70b of the Peltier elements 7A to 7C sufficiently dissipate heat to the cooling water, so that the cooling water is sufficiently heated. The heated cooling water is cooled in the radiator 3 by heat exchange with the air around the radiator 3.

<Heating operation>
During the heating operation, as shown in FIG. 4, the controller 5 operates the second pump P2 and the radiator fan 3e, respectively. Further, the controller 5 starts power feeding to the Peltier elements 7d to 7f while controlling the direction of the current so that the one surface 70a side of each of the Peltier elements 7D to 7F becomes a heat dissipation surface and the other surface 70b side becomes a heat absorption surface. . Note that power is not supplied to the other Peltier elements 7A to 7C.

  Thereby, in this air conditioner, the cooling water circulates between the air conditioning core 100 and the radiator 3 in the direction of the solid line arrow in FIG. In this state, each of the other surfaces 70b of the Peltier elements 7e to 7f absorbs heat from the cooling water flowing in the lower second tube 15, and each one surface 70a is directed upward to the water in the first liquid channel 111. To dissipate heat.

  In this air conditioning core 100, each upward first tube 11 extends vertically so that water is convected in the upward first liquid flow path 111, and the lower second tube 15 is orthogonal to the extending direction of each upward first tube 11. Yes. Each upward first tube 11 includes an annular tube 110a and straight tubes 110b and 110c, and each surface 70a of each Peltier element 7D to 7F is in contact with each straight tube 110b and 110c. . For these reasons, in this air conditioning core 100, water sufficiently convects in each upward first tube 11 in the direction of the dashed arrow in the figure, and heat is generated between each surface 70a of each Peltier element 7D to 7F and the water. Is more fully movable.

  This case will be described in more detail. Water in the vicinity of each surface 70a is heated in each upward first liquid channel 111 by heat radiation by each surface 70a of the Peltier elements 7D to 7F. The heated water has a reduced specific gravity and rises upward in the first liquid flow path 111 toward the upper second tube 13, that is, circulates upward. On the other hand, by moving away from each surface 70a, a temperature difference occurs between the water in the vicinity of each surface 70a and the specific gravity becomes heavy. For this reason, the water in a position far from each surface 70a circulates in the first liquid channel 111 upward along the direction of gravity toward each surface 70a. As a result, water convection occurs in the upward first tube 11. As in the cooling operation, the convection of the water promotes the movement of heat by the Peltier elements 7D to 7F.

  Thus, in this air conditioning core 100, each surface 70a of each Peltier element 7D-7F sufficiently dissipates heat to the water, so that the water is sufficiently heated. For this reason, the air around each fin 17 is heated suitably. Then, when the controller 5 operates the air conditioning fan 100a, the heated air is supplied to the vehicle interior, and the vehicle interior is heated.

  On the other hand, the other surfaces 70b of the Peltier elements 7D to 7F sufficiently absorb heat from the cooling water, so that the cooling water is sufficiently cooled. The cooled cooling water is heated in the radiator 3 by heat exchange with the air around the radiator 3.

<High load heating operation>
Further, in the case where it is necessary to perform rapid heating with a higher load, such as immediately after the start of the vehicle in a cold environment, in addition to the above-described heating operation state, as shown in FIG. While the one pump P1 is also operated, the current direction is controlled so that the one surface 70a side of the Peltier elements 7A to 7C becomes a heat radiating surface and the other surface 70b side becomes a heat absorbing surface, and power is supplied to the Peltier elements 7A to 7C. Start.

  As a result, the cooling water also flows through the upper second tube 13 in the direction of the solid arrow in FIG. Each Peltier element 7 </ b> A to 7 </ b> C absorbs heat from the cooling water and radiates heat to the water in each downward first tube 9. Thereby, the water in the downward first tube 9 is heated. For this reason, not only the fins 17 in each upward first tube 11 but also the air around each fin 17 in each downward first tube 9 is heated. When the controller 5 operates the air conditioning fan 100a in this state, higher-temperature air can be supplied into the vehicle interior.

  In the above case, since the gravity direction and the convection direction of water do not follow, the convection of water hardly occurs in each downward first tube 9. For this reason, the water in each downward first tube 9 is not heated as much as the water in the upward first tube 11. For this reason, the heating of the air by the fin 17 in each downward first tube 9 functions in an auxiliary manner.

<High-load cooling operation>
As in the high load heating operation, in the cooling operation state shown in FIG. 3, the controller 5 operates the second pump P <b> 2, and the one surface 70 a side of the Peltier elements 7 </ b> D to 7 </ b> F is used as the heat absorption surface. High power cooling operation can also be performed by supplying power to the Peltier elements 7D to 7F using the 70b side as a heat dissipation surface. In this case, the cooling heat of the water in each upward first tube is used as an auxiliary.

  In the air conditioning core 100, the controller 5 is configured to adjust the power supplied to the Peltier elements 7A to 7F based on the temperature of water detected by the temperature sensors 19a to 91f during each cooling operation and each heating operation. To control. For this reason, water is suitably cooled or heated by the Peltier elements 7A to 7F during each cooling operation and each heating operation.

  Therefore, according to the air conditioner provided with the air conditioning core 100, the vehicle interior can be suitably air-conditioned.

  In the air conditioning core 100, the downward first tubes 9 and the upward first tubes 11 are alternately provided in the horizontal direction. Therefore, as described above, each downward first tube 9 and each upward first tube 11 is efficiently arranged so that the direction of water convection in each downward first tube 9 and each upward first tube 11 is in the direction of gravity. And can be arranged. For this reason, in this air conditioning core 100, it is possible to suitably air-condition the vehicle interior while reducing the size of the casing.

  In addition, each downward first tube 9 and each upward first tube 11 is provided with fins 17 that can contact external air. For this reason, it becomes possible to discharge | release the heat | fever or cold heat of the water in each downward 1st tube 9 and each upward 1st tube 11 to air efficiently. For this reason, in this air conditioning core 100, the movement of heat by the Peltier elements 7A to 7F is more suitably performed. For this reason, in this air conditioning core 100, it is possible to air condition the vehicle interior more suitably.

(Example 2)
The air conditioner of the second embodiment includes an air conditioner core 101 as shown in FIG. 6 instead of the air conditioner core 100 in the air conditioner of the first embodiment.

  In addition to the components of the air conditioning core 100 described above, the air conditioning core 101 is also provided between the lower second tube 15 and each downward first tube 9 and between the upper second tube 13 and each upward first tube 11. Peltier elements 7G to 7L are provided. Specifically, Peltier elements 7 </ b> G to 7 </ b> I are respectively provided between the upper second tube 13 and the upward first tubes 11, and the Peltier elements are provided between the lower second tube 15 and the downward first tubes 9. Elements 7J to 7L are respectively provided. These Peltier elements 7G to 7L have the same configuration as the Peltier elements 7A to 7F, and are electrically connected to the battery 5a, respectively. Further, each surface 70a of each Peltier element 7G to 7I is in contact with each other end of the straight tubes 110b and 110c in each upward first tube 11. Similarly, each surface 70a of each Peltier element 7J to 7L is in contact with each other end of the straight tubes 90b and 90c in each downward first tube 9. Further, the upper second tube 13 and the lower second tube 15 are formed to have a longer overall length than the upper second tube 13 and the lower second tube 15 in the air conditioning core 100 shown in FIG. Other configurations of the air conditioning core 101 are the same as those of the air conditioning core 100, and the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the air conditioner provided with the air conditioning core 101, similarly to the air conditioner of the first embodiment, it is possible to perform a cold book operation, a heating operation, a high load heating operation, and a high load cooling operation, respectively.

  Further, in the air-conditioning core 101 during the high load heating operation, the controller 5 replaces the power supply to the Peltier elements 7A to 7C, and the one surface 70a side of the Peltier elements 7J to 7L serves as a heat dissipation surface, and the other surface 70b side Power supply to the Peltier elements 7J to 7L is started while controlling the direction of the current so as to be the heat absorption surface. That is, high load heating operation is performed by supplying power to the Peltier elements 7D to 7F and 7J to 7L. At this time, the controller 5 stops the operation of the first pump P1.

  Thereby, also in each downward 1st tube 9, the convection of water arises in the same state as each upward 1st tube 11 (refer the broken line arrow in Drawing 6). For this reason, water is also sufficiently heated by each surface 70a of each Peltier element 7J-7L. For this reason, not only the fins 17 in each upward first tube 11 but also the air around each fin 17 in each downward first tube 9 is sufficiently heated. When the controller 5 operates the air conditioning fan 100a in this state, higher-temperature air can be supplied into the vehicle interior.

  Even in the high load cooling operation, in the air conditioning core 101, the controller 5 replaces the power supply to the Peltier elements 7D to 7F, and the one surface 70a side of the Peltier elements 7G to 7I becomes the heat absorption surface, and the other surfaces 70b. Power supply to the Peltier elements 7G to 7I is started while controlling the direction of current so that the side becomes the endothermic surface. That is, high-load cooling operation is performed by supplying power to the Peltier elements 7A to 7C and 7G to 7I. At this time, the controller 5 stops the operation of the second pump P2 and operates the first pump P1.

  In this case, water convection occurs in each upward first tube 11 in the same state as each downward first tube 9. For this reason, more cooled air can be supplied into the vehicle interior.

  Thus, in this air conditioner, when performing high-load heating operation, the heat of water in each downward first tube 9 is supplementarily used by supplying power to the Peltier elements 7A to 7C, and the Peltier element 7J It is possible to selectively use the case where the heat of the water in each downward first tube 9 that is heated further is used by supplying power to ˜7L. In addition, when performing high-load cooling, the cooling of water in each upward first tube 11 is supplementarily used by supplying power to the Peltier elements 7D to 7F, and by supplying power to the Peltier elements 7G to 7I. Thus, it is possible to selectively use the cooling of the water in each upward first tube 11 that has been cooled.

(Example 3)
As shown in FIG. 7, the air conditioner according to the third embodiment includes an air conditioning core 200, a radiator 30, and a controller 50. The controller 50 is connected to a battery 50a as a power source.

  The air conditioning core 200 includes a plurality of Peltier elements 7 </ b> A to 7 </ b> D, a plurality of first tubes 31, and a second tube 33. The second tube 33 is disposed below the first tube 31. Further, in the vicinity of the air conditioning core 200, a heating fan 200a and a cooling fan 200b are provided. Each Peltier element 7A-7D, the heating fan 200a, and the cooling fan 200b are electrically connected to the battery 50a. In addition, each Peltier device 7A-7D is comprised so that a heat absorption surface and a heat radiating surface can be switched by the one surface 70a side and the other surface 70b side.

  The first tube 31 includes an annular tube 310a and straight tubes 310b and 310c. The annular tube 310a and the straight tubes 310b and 310c are formed with a first liquid channel 311 through which water can flow. The first tube 31 extends vertically in a direction away from the second tube 33. The first tube 31 is provided with fins 17. Further, one of the plurality of first tubes 31 is provided with a temperature sensor 19a. The temperature sensor 19a is electrically connected to the battery 50a.

  The second tube 33 extends horizontally perpendicular to the direction in which the first tube 31 extends. The second tube 33 is formed with a second liquid channel 34 through which cooling water can flow and an inlet 33a and an outlet 33b communicating with the second liquid channel. Yes. The second tube 33 is provided with a known drive mechanism 37 connected to the motor 35. With this drive mechanism 37, in the air conditioning core 200, the second tube 33, the Peltier elements 7 </ b> A to 7 </ b> D, and the first tubes 31 can rotate around the horizontal axis H of the second tube 33. The motor 35 is electrically connected to the battery 50a shown in FIG.

  The Peltier elements 7 </ b> A to 7 </ b> D are provided in an aligned state between the second tube 33 and each first tube 31. In each of these Peltier elements 7 </ b> A to 7 </ b> D, one surface 70 a is adjacent to each first tube 31, and each other surface 70 b is adjacent to the second tube 33. In addition, in this way, each surface 70a of each Peltier element 7A to 7D and each first tube 31 are adjacent to each other, so that each surface 70a of each Peltier element 7A to 7D and the straight tube 310b in each first tube 31. , 310c are in contact with each end.

  The radiator 30 has an outlet 30a and an inlet 30b. The other configuration of the radiator 30 is the same as that of the radiator 3 shown in FIG. Further, a radiator fan 30 c is provided in the vicinity of the radiator 3. The radiator fan 30c is electrically connected to the battery 50a shown in FIG.

  As shown in FIG. 1, the radiator 30 outlet 30 a and the inlet 33 a of the second tube 33 are connected by a pipe 39. Further, the inlet 30 b of the radiator 3 and the outlet 33 b of the second tube 33 are connected by a pipe 41. Cooling water circulates in the pipes 39 and 41. The piping 41 is provided with a first pump P1. The first pump P1 is electrically connected to the battery 50a. In addition, the 1st pump P1 may be provided in the piping 39 side shown in FIG.

  The controller 50 and the battery 50a have the same configuration as the controller 5 and the battery 5a shown in FIG. 2, respectively, and the controller 50 controls the Peltier elements 7A to 7D and the like based on the control signal of the temperature sensor 19a. The controller 50 can perform control for each of the individual Peltier elements 7A to 7D. The battery 50a functions as a power source for the Peltier elements 7A to 7D and the like.

  In the air conditioner configured as described above, heating operation or cooling operation is performed as follows.

<Heating operation>
During the heating operation, the controller 50 operates the motor 35, and the drive mechanism 37 rotates the air conditioning core 200 around the horizontal axis H of the second tube 33 so that the second tube 33 is positioned below the first tube 31. Let In this state, each first tube 31 extends upward with respect to the second tube 33. Further, the controller 50 starts feeding the Peltier elements 7A to 7D while controlling the direction of the current so that the one surface 70a side of each of the Peltier elements 7A to 7D becomes a heat dissipation surface and the other surface 70b side becomes a heat absorption surface. Then, the controller 50 operates the first pump P1 and the radiator fan 30c, respectively. Thereby, in this air conditioner, the cooling water circulates between the air conditioning core 200 and the radiator 30 in the direction of the solid line arrow in FIG.

  Thereby, each other surface 70b of the Peltier elements 7A to 7D absorbs heat from the cooling water, and each one surface 70a dissipates heat from the water. Also in this air conditioning core 200, each first tube 31 extends vertically so that water is convected in the first liquid flow path 311, and the second tube 33 is orthogonal to the direction in which the first tube 31 extends. Each first tube 31 includes an annular tube 310a and straight tubes 310b and 310c, and each surface 70a of each Peltier element 7A to 7D is in contact with each straight tube 310b and 310c. For these reasons, the heated water convects in each first tube 31 along the direction of gravity in the direction of the broken line arrow in FIG. 7 in the same manner as the water in the upward first liquid flow path 111 shown in FIG. . For this reason, the movement of heat is promoted by the convection of water, and the heat can move more sufficiently between the one surface 70a of each Peltier element 7A to 7D and the water.

  For this reason, the air which contacts each fin 17 in each 1st tube 31 is heated suitably. In this state, when the controller 50 operates the heating fan 200a, the heated air is supplied to the vehicle interior and the vehicle interior is heated.

  The cooling water cooled by receiving heat absorbed by the Peltier elements 7 </ b> A to 7 </ b> D is heated by heat exchange with air around the radiator 3 in the radiator 3.

<Cooling operation>
During the cooling operation, the controller 50 operates the motor 35, and the drive mechanism 37 reverses the air conditioning core 200 around the horizontal axis H of the second tube 33 from the state of the air conditioning core 200 during the heating operation. Thereby, as shown in FIG. 8, the 2nd tube 33 will be located in the upper part of each 1st tube 31. As shown in FIG. In this state, each first tube 31 extends downward with respect to the second tube 33. Further, the controller 50 starts feeding the Peltier elements 7A to 7D while controlling the direction of the current so that the one surface 70a side of the Peltier elements 7A to 7D becomes a heat absorbing surface and the other surface 70b side becomes a heat radiating surface. Then, the controller 50 operates the first pump P1 and the radiator fan 30c, respectively. Thereby, in this air conditioner, the cooling water circulates between the air conditioning core 200 and the radiator 30 in the direction of the solid line arrow in FIG.

  Thereby, each other surface 70b of the Peltier elements 7A to 7D radiates heat to the cooling water, and each one surface 70a absorbs heat to the water. Therefore, the cooled water convects in each first tube 31 in the direction of the arrow in FIG. 8 along the direction of gravity in the same manner as the water in the downward first liquid channel 91 shown in FIG. For this reason, even during the cooling operation, the movement of heat is promoted by the convection of water, and the heat can move more sufficiently between each surface 70a of each Peltier element 7A to 7D and the water.

  For this reason, the air around each fin 17 in each first tube 31 is suitably cooled. In this state, when the controller 50 operates the cooling fan 200b, the cooled air is supplied into the vehicle interior, and the vehicle interior is cooled.

  Also in the air conditioning core 200, the controller 50 controls the strength of the power supplied to the Peltier elements 7A to 7D based on the temperature of water detected by the temperature sensor 19a during the heating operation and the cooling operation. For this reason, water is suitably cooled or heated by the Peltier elements 7A to 7D during the cooling operation and the heating operation.

  As described above, in the air conditioning core 200, the second tube 33, the Peltier elements 7 </ b> A to 7 </ b> D, and the first tubes 31 are rotatable around the horizontal axis H of the second tube 33. For this reason, by reversing the second tube 33, the Peltier elements 7A to 7D and the first tubes 31, respectively, the direction of water convection in the first tubes 31 in the direction of gravity during heating and cooling. It is possible to be along. For this reason, even if it is this air-conditioning core 200, the movement of the heat by Peltier device 7A-7D is performed suitably.

  Therefore, even with an air conditioner equipped with the air conditioning core 200, the passenger compartment can be suitably air conditioned.

Example 4
The air conditioner of the fourth embodiment includes an air conditioner core 201 as shown in FIG. 9 instead of the air conditioner core 200 in the air conditioner of the third embodiment. In the air conditioning core 201, a part of the configuration of the air conditioning core 200 is changed, and the drive mechanism 37 is not provided in the second tube 33. In addition, one air conditioning fan 201 a is provided in the vicinity of the air conditioning core 201. The air conditioning fan 201a is electrically connected to the battery 50a. Other configurations of the air conditioning core 201 are the same as those of the air conditioning core 200.

  In this air conditioner, the radiator 30 and the air conditioning core 201 are connected by pipes 40a, 40b, 42a, and 42b. A known drive mechanism 38a is provided between the pipe 40a and the pipe 40b, and a drive mechanism 38a is provided between the pipe 42a and the pipe 42b. More specifically, the radiator 30 outlet 30a and the drive mechanism 38a are connected by a pipe 40a, and the drive mechanism 38a and the inlet 33a of the second tube 33 are connected by a pipe 40b. The outlet 33b of the second tube 33 and the drive mechanism 38b are connected by a pipe 42a, and the drive mechanism 38b and the radiator 30 inlet 30b are connected by a pipe 42b.

  The drive mechanisms 38a and 38b are respectively connected to the motor 35, and these drive mechanisms 38a and 38 can rotate the pipes 40b and 42a around the horizontal axis H by the drive of each motor 35. For this reason, in the air conditioning core 201, the second tube 33, the Peltier elements 7A to 7D, and the first tubes 31 are rotatable around the horizontal axis H of the drive mechanisms 38a and 38b. Other configurations are the same as those of the air conditioner of the third embodiment.

  In the air conditioner configured as described above, heating operation or cooling operation is performed as follows.

<Heating operation>
During the heating operation, the driving mechanisms 38a and 38b rotate the pipes 40b and 42a by operating the motors 35, so that the second tube 33 is positioned horizontally so that the second tube 33 is positioned below the first tube 31. The air conditioning core 201 is rotated around the axis H. Thereby, like the air conditioning core 200 in Example 3 shown in FIG. 7, the convection of water arises suitably in the 1st tube 31 (refer the broken-line arrow in FIG. 9). The air heated by the fins 17 is supplied to the vehicle interior by the air conditioning fan 201a, and the vehicle interior is heated.

<Cooling operation>
During the cooling operation, the drive mechanisms 38a and 38b reverse the air conditioning core 201 around the horizontal axis H by reversing the pipes 40b and 42a from the state during the heating operation by the operation of each motor 35. As a result, as shown in FIG. 10, the second tube 33 is positioned above each first tube 31. Thereby, like the air conditioning core 200 in Example 3 shown in FIG. 8, the convection of water arises suitably in the 1st tube 31 (refer the broken-line arrow in FIG. 10). The air cooled by the fins 17 is supplied to the vehicle interior by the air conditioning fan 201a, and the vehicle interior is cooled.

  In this air conditioning apparatus, unlike the air conditioning core 200 in the third embodiment, air heated or cooled by the air conditioner 201 is supplied into the vehicle interior by the single air conditioning fan 201 during the air conditioning core 201 heating operation and cooling operation. The For this reason, compared with the air conditioner of Example 3, this air conditioner can reduce the manufacturing cost. Moreover, in this air conditioner, compared with the air conditioner of Example 3, the rotation radius when rotating the air conditioning core 201 can be reduced. For this reason, this air conditioner is more mountable on the vehicle than the air conditioner of the third embodiment. Other functions and effects are the same as those of the air conditioner of the third embodiment.

(Example 5)
The air conditioner of the fifth embodiment includes an air conditioning core 300 shown in FIG. 11 instead of the air conditioning core 200 of the third embodiment shown in FIG.

  The air conditioning core 300 includes a plurality of first tubes 61. A first liquid channel 611 is formed in the first tube 61. Each first tube 61 is in contact with one surface 70a of each of the Peltier elements 7A to 7D at one end, and extends vertically from the one surface 70a in a direction remote from each surface 70a. Each first tube 61 is provided with corrugated fins 170. Other configurations are the same as those of the air conditioning core 200 of the third embodiment.

  In this air conditioning core 300, the water in each first liquid channel 611 is heated by the heat radiation of each surface 70a of the Peltier elements 7A to 7D during the heating operation. Also in this case, since each first tube 61 extends in the vertical direction upward from each one surface 70a, water flows in each first liquid channel 611 in the direction of gravity. For this reason, as shown by the broken-line arrows in FIG. 11, water convects in the first tubes 61 along the direction of gravity.

  Further, during the cooling operation, the second tube 33, the Peltier elements 7A to 7D, and the first tubes 61 are reversed, so that the water cooled by the heat absorption of each surface 70a of the Peltier elements 7A to 7D is the first. Convection in the tube 61 along the direction of gravity.

  For these reasons, also in this air conditioning core 300, heat can sufficiently move between each surface 70a of each Peltier element 7A to 7D and water. Other functions and effects are the same as those of the air conditioning core 200 and the air conditioner of the third embodiment.

(Example 6)
The air conditioner according to the sixth embodiment includes an air conditioning core 400 illustrated in FIG. 12 instead of the air conditioning core 200 according to the third embodiment illustrated in FIG. 7.

  The air conditioning core 400 includes a first tube 62. The first tube 62 includes a horizontally formed horizontal tube 620a and straight tubes 620b and 620c communicating with the horizontal tube 620a only at one end. In addition, a first liquid channel 621 is formed in the horizontal tube 620a and the straight tubes 620b and 620c. The first tube 62 extends vertically in a direction away from the one surface 70a of the Peltier elements 7A to 7D. Further, the first tube 62 is provided with corrugated fins 170. The first tube 62 is provided on each surface 70a of the Peltier elements 7A to 7D. Other configurations are the same as those of the air conditioning core 200 in the third embodiment.

  In this air conditioning core 400, since one end side of each of the straight tubes 620b and 620c communicates with the horizontal tube 620a, water is easily convected in the first tube 62 during heating and cooling (FIG. 12). (See dashed arrow inside.) In addition, the first tube 62 can be easily manufactured. Other functions and effects are the same as those of the air conditioning core 200 and the air conditioner of the third embodiment.

(Example 7)
The air conditioner according to the seventh embodiment includes an air conditioning core 500 illustrated in FIG. 13 instead of the air conditioning core 200 according to the third embodiment illustrated in FIG. 7.

  The air conditioning core 500 includes a first tube 63. The first tube 63 includes a lane-shaped horizontal tube 630a formed in the same width as the one surface 70a of the Peltier elements 7A to 7D, and a straight tube 630b that is also formed in the lane shape and communicates with the horizontal tube 630a only at one end, 630c. A first liquid channel 631 is formed in the horizontal tube 630a and the straight tubes 630b and 630c. The first tube 63 extends vertically toward the direction remote from the one surface 70a of the Peltier elements 7A to 7D. Other configurations are the same as those of the air conditioning cores 200 and 400 in the third and sixth embodiments.

  In the air conditioning core 500, the first liquid channel 631 is widely formed by forming the first tube 63 in a lane shape. For this reason, water is more easily convected in the first tube 63 (see the broken line arrow in FIG. 13). Other functions and effects are the same as those of the air conditioning cores 200 and 400 and the air conditioners of the third and sixth embodiments.

(Example 8)
The air conditioner of the eighth embodiment includes an air conditioning core 600 shown in FIG. 14 instead of the air conditioning core 200 of the third embodiment shown in FIG.

  The air conditioning core 600 includes a first tube 64. The first tube 64 extends in the vertical direction and is bent a plurality of times. In addition, a first liquid channel 641 is formed in the first tube 64. The first tube 64 is provided with corrugated fins 170. The first tube 64 is provided on each surface 70a of the Peltier elements 7A to 7D. The first tube 64 extends vertically in a direction away from the one surface 70a of the Peltier elements 7A to 7D. The first tube 64 is provided on each surface 70a of the Peltier elements 7A to 7D. Other configurations are the same as those of the air conditioning core 200 in the third embodiment.

  In the air conditioning core 600, since the first tube 64 is bent a plurality of times, water convects in the first liquid channel 641 while heating and cooling, and convects in the first tube 64. (See broken line arrows in FIG. 14). At this time, convective water is heated or cooled by sensible heat in addition to latent heat. For this reason, heat can move more fully between each surface 70a of each Peltier element 7A-7D and water. Other functions and effects are the same as those of the air conditioning core 200 and the air conditioner of the third embodiment.

Example 9
The air conditioner according to the ninth embodiment includes an air conditioning core 700 illustrated in FIG. 15 instead of the air conditioning core 200 according to the third embodiment illustrated in FIG. 7.

  The air conditioning core 700 includes a first tube 65. The first tube 65 is bent a plurality of times and is formed in an annular shape. In addition, a first liquid channel 651 is formed in the first tube 65. Other configurations are the same as those of the air conditioning cores 200 and 600 in the third and eighth embodiments.

  In the air conditioning core 700, since the first tube 65 has an annular shape, water can easily flow through the first liquid flow path 651, and water can easily convect through the first tube 65 (FIG. (See dashed arrow in 15). For this reason, the effect of the 1st tube 64 in said air-conditioning core 600 shown in FIG. 14 is heightened more. Other functions and effects are the same as those of the air conditioning cores 200 and 600 and the air conditioners of the third and eighth embodiments.

(Example 10)
The air conditioner of Example 10 includes an air conditioning core 800 shown in FIG. 16 instead of the air conditioning core 200 of Example 3 shown in FIG.

  The air conditioning core 800 includes Peltier elements 7 </ b> A to 7 </ b> C and a first tube 66. The first tube 66 has a shape that is bent a plurality of times while extending in the vertical direction between the Peltier elements 7A to 7C. A first liquid channel 661 is formed in the first tube 66. The first tube 66 is provided with corrugated fins 170. The first tube 66 extends vertically in a direction away from the one surface 70a of the Peltier elements 7A to 7C. Other configurations are the same as those of the air conditioning core 200 in the embodiment.

  In the air conditioning core 800, water flows through the first liquid channel 661 between the Peltier elements 7A to 7C during heating and cooling, so that water convects in the first tube 66 (see the broken line arrow in FIG. 16). .) For this reason, heat can move sufficiently between each surface 70a of the Peltier elements 7A to 7C and water. In the air conditioning core 800, at the time of heating and cooling, for example, the current supplied only to the Peltier element 7A is increased so that only a part of the first liquid channel 661 is heated or cooled. Thereby, water can be suitably convected by the first tube 66 with this part as a base point. Other configurations are the same as those of the air conditioning core 200 of the third embodiment.

(Example 11)
The air conditioner of Example 11 includes an air conditioning core 900 shown in FIG. 17 instead of the air conditioning core 200 of Example 3 shown in FIG.

  The air conditioning core 900 includes Peltier elements 7 </ b> A to 7 </ b> C and a first tube 67. The first tube 67 is formed in an annular shape by being bent a plurality of times between the Peltier elements 7A to 7C. In addition, a first liquid channel 671 is formed in the first tube 67. Other configurations are the same as those of the air conditioning cores 200 and 800 in the embodiments 2 and 10.

  In the air conditioning core 900, since the first tube 67 has an annular shape, water can easily flow through the first liquid flow path 671, and water can easily convect through the first tube 67 (FIG. (See dashed arrow in 17). For this reason, the effect of the 1st tube 66 in said air-conditioning core 800 shown in FIG. 16 is heightened more. Other functions and effects are the same as those of the air conditioning cores 200 and 800 and the air conditioners of the embodiments 2 and 10.

  In the above, the present invention has been described with reference to the first to eleventh embodiments. However, the present invention is not limited to the first to eleventh embodiments, and can be applied with appropriate modifications without departing from the spirit of the present invention.
