Description

  The present invention relates to a heat exchanger for air conditioning.

  Patent Document 1 discloses a cooler core used in a low-temperature storage. The cooler core includes a plurality of Peltier modules and a support member on which each Peltier module is mounted. Each Peltier module has a Peltier element in which a thermoelectric conversion chip is arranged via an electrode so that one surface side is a heat absorbing surface and the other surface side is a heat radiating surface, a first fin fixed to one surface side, and a second surface side And a fixed second fin. A lead wire for connecting to a power source is connected to the electrode of each Peltier element.

  The cooler core is assembled by attaching each Peltier module to a support member and connecting the lead wires of each Peltier element to a power source.

  When this cooler core is used, for example, in an air conditioner, if current is supplied from the power source to the electrodes of the Peltier element, heat is absorbed on one side of the Peltier element and heat is released on the other side of the Peltier element. For this reason, in this cooler core, it is possible to cool the room by absorbing heat from the air on one side of the Peltier element to cool the air.

  In this cooler core, a plurality of Peltier modules are attached to the support member, and each of these Peltier modules is configured to be detachable from the support member. For this reason, in this cooler core, when a malfunction occurs in a certain Peltier element, it is not necessary to replace the entire cooler core, and it is possible to replace only the Peltier module having the malfunctioning Peltier element individually. . For this reason, with this cooler core, it is possible to reduce the repair cost in the event of a malfunction.

JP-A-9-119744

  However, in the above-described conventional cooler core, when the Peltier module is attached or detached at the time of manufacture or replacement of the Peltier module, not only the attachment or removal of the Peltier module to the support member, but also the connection or removal of the lead wire and the power source is separately performed Is required. For this reason, in this cooler core, the burden at the time of attachment or detachment work of a Peltier module is large.

  Further, in this cooler core, as described above, since a lead wire must be connected separately from the attachment of the Peltier module, an electrical connection failure is likely to occur. For this reason, there is a concern that the quality of the cooler core may deteriorate.

  This invention is made | formed in view of the said conventional situation, Comprising: While attaching / detaching work of a Peltier module is easy, it is set as the problem which should be solved to provide a high quality air conditioner heat exchanger.

The heat exchanger for air conditioning of the present invention is fixed to the Peltier element in which the thermoelectric conversion chip is arranged via the electrode so that the heat absorption surface and the heat dissipation surface can be switched between the one surface side and the other surface side. A Peltier module having a first fin and a second fin fixed to the other surface;
An air conditioning heat exchanger comprising an inner passage through which a heat exchange medium can be circulated and a tube to which the Peltier module is attached,
The tube communicates with the inner path, has an opening for mounting the Peltier module, and is embedded with wiring connected to a power source,
The opening is sealed by the Peltier module in a state where the second fin is disposed in the inner path,
The tube and the Peltier module are configured such that the electrode and the wiring can be electrically connected by mounting the Peltier module on the tube (Claim 1).

  In the heat exchanger for air conditioning of the present invention, the conventional lead wire is not provided in the electrode of each Peltier element, and the wiring is embedded in the tube. And if a Peltier module is attached to a tube, an electrode and wiring will be electrically connected. For this reason, in this heat exchanger for air conditioning, when the Peltier module is attached to or removed from the tube at the time of manufacture or replacement of the Peltier module, the electrical connection between the Peltier element and the wiring or Removal can be performed simultaneously.

  Further, in this heat exchanger for air conditioning, since the electrodes of the Peltier element can be electrically connected to the wiring simply by attaching the Peltier module when the Peltier module is mounted, poor electrical connection is unlikely to occur.

  The heat exchanger for air conditioning according to the present invention absorbs heat on one surface side of the Peltier element and becomes a cooler core that performs cooling on one surface side if heat is radiated to the heat exchange medium on the other surface side. In addition, this air conditioner heat exchanger radiates heat on one side of the Peltier element and becomes a heater core for heating on one side if heat is absorbed from the heat exchange medium on the other side. At this time, the first and second fins provided on the one surface side and the other surface side increase the respective surface areas on the one surface side and the other surface side of the Peltier element, so that heat absorption and heat dissipation by the Peltier element are performed efficiently.

  Therefore, the heat exchanger for air conditioning according to the present invention can easily attach and detach the Peltier module and can exhibit high quality.

  In the heat exchanger for air conditioning according to the present invention, it is preferable that a fixing means is provided between the tube and the Peltier module so that the Peltier module is fixed to the tube by mounting the Peltier module on the tube. . This facilitates the mounting operation of the Peltier module on the tube, makes it difficult to remove the Peltier module, and improves the quality of the heat exchanger for air conditioning.

  Moreover, in the heat exchanger for air conditioning of this invention, the heat exchange medium which distribute | circulates an inner channel may be either gas or a liquid. For example, air can be used as the gas. Moreover, water, an antifreeze liquid, etc. are employable as a liquid. In this heat exchanger for air conditioning, since the opening of the tube is sealed by attaching the Peltier module to the tube, it is difficult for the heat exchange medium flowing in the inner passage to leak out of the tube. In the heat exchanger for air conditioning according to the present invention, cooling or heating may be performed by a heat exchange medium that circulates in the inner passage.

  Furthermore, in the heat exchanger for air conditioning of the present invention, one Peltier module may be attached to the tube, or a plurality of Peltier modules may be attached. If a plurality of Peltier modules are attached to the tube, the individual Peltier modules can be easily attached and detached, and the above-described effects of the present invention become more prominent.

  The wiring may have a connection portion that is exposed from the tube at the opening and is electrically connected to the electrode. In this case, the wiring and the electrode can be easily connected.

  As the Peltier element, various elements can be adopted as long as the thermoelectric conversion chip is arranged through the electrode so that the one surface side becomes the heat absorption surface or the heat dissipation surface and the other surface side becomes the heat dissipation surface or the heat absorption surface.

  For example, the Peltier element is formed on a first insulating substrate that forms one surface side, a second insulating substrate that forms the other surface side, and the first insulating substrate or the second insulating substrate, and is electrically connected to the thermoelectric conversion chip. The first electrode which is a part of the electrode to be formed and the second electrode which is the remaining part of the electrode which is formed on the second insulating substrate or the first insulating substrate and which is electrically connected to the thermoelectric conversion chip. In this case, the connection portion may include a first connection portion that is electrically connected to the first electrode and a second connection portion that is electrically connected to the second electrode. And between the 1st electrode and the 1st connection part and between the 2nd electrode and the 2nd connection part can be constituted so that elastic deformation is possible (Claim 3).

  When the Peltier element and the wiring configured as described above are employed, when the Peltier module is attached to or detached from the tube, the first electrode and the first connection portion are elastically deformed, and the second electrode and the second electrode are elastically deformed. Elastic deformation occurs between the connecting part. For this reason, electrical connection or removal with respect to the Peltier module is facilitated, and as a result, attachment / detachment work of the Peltier module with respect to the tube becomes easier. In addition, since each electrode and each connection portion are elastically deformed, electrical connection to the Peltier module is difficult to disconnect even after the Peltier module is mounted on the tube. For this reason, the quality of the heat exchanger for air conditioning itself improves more.

  As a means for configuring the first electrode and the first connection portion so as to be elastically deformable, a coil spring made of a conductive material may be provided between the first electrode and the first connection portion. Such a coil spring may be provided integrally with the electrode or the first connection portion. The same applies to the means for allowing elastic deformation between the second electrode and the second connecting portion.

  A plurality of openings are formed in the tube in the circumferential direction, and a Peltier module can be attached to each opening. And it is preferable that each Peltier module is mutually fixed by each 2nd fin arrange | positioned in the inner path.

  In this case, since the respective Peltier modules are fixed to each other by the second fins or the like, the respective Peltier modules are not easily detached from the tube even after the respective Peltier modules are attached to the tube. For this reason, the quality of the heat exchanger for air conditioning itself improves. In this heat exchanger for air conditioning, since a plurality of Peltier modules are attached to the tube, heat absorption and heat dissipation by the Peltier element in each Peltier module is more suitably performed, and the heat exchanger for air conditioning Cooling or heating is more preferably performed.

  In the heat exchanger for air conditioning of the present invention, a plurality of tubes can be provided in parallel to each other. The air conditioner heat exchanger is provided on one end side of each tube, and includes a first head in which a first collective path that communicates with each inner passage and can flow a heat exchange medium is formed, and each tube. It is preferable that the second head is provided with a second head that is provided on the other end side and in which a second collecting path that communicates with each inner path and allows the heat exchange medium to flow therethrough is formed.

  In this case, the air conditioning heat exchanger includes more Peltier modules via a plurality of tubes, and cooling or heating by the air conditioning heat exchanger is more suitably performed. In addition, the inner paths in each tube communicate with each other via the first collecting path of the first head and the second collecting path of the second head. For this reason, even when a plurality of tubes are provided, the heat exchanger for air conditioning does not increase in size.

  In this case, the Peltier modules are inclined with respect to the juxtaposed direction of the tubes in a virtual vertical plane perpendicular to the flow direction of the heat exchange medium so as to avoid mutual interference or interference with the tubes. It is preferable to be attached to each tube. In this case, the attaching / detaching operation of the Peltier module with respect to the tube becomes easy.

  It is preferable that the tube is provided with a sealing material for preventing contact between the connecting portion and the heat exchange medium (Claim 7). In this case, when a liquid is employed as the heat exchange medium, it is possible to effectively prevent a short circuit from occurring between the connection portion and the electrode due to the liquid. As the sealing material, an O-ring or a gasket can be employed, and a caulking material or the like can be employed.

  Each first fin 17 is fixed to the first insulating substrate 21 and has a plurality of heat dissipation plates 17a. Each second fin 19 is fixed to the second insulating substrate 23 side and has a plurality of heat radiating plates 19a. In each heat sink 17a of each first fin 17 and each heat sink 19a of each second fin 19, the flow direction of the cooling water and the flow direction of the air are orthogonal to each other. Specifically, each heat sink 17a of each first fin 17 extends along the flow direction of the air sent by the electric fan 100a as shown in FIGS. Can be reduced. On the other hand, each heat sink 19a of each second fin 19 is formed along the flow direction of the cooling water in each of the tubes 9 to 11 (see the arrow in FIG. 2), and the channel resistance against the cooling water. Can be reduced. In addition, about the shape of the 1st, 2nd fins 17 and 19, it is not restricted to plate shape, For example, it can also form in a waveform. Moreover, the 1st fin 17 and the 2nd fin 19 of a respectively different shape can also be employ | adopted.

  As shown in FIG.1 and FIG.2, the 1st-3rd tubes 9-11 are formed with the insulator, The 1st-3rd internal passages 9a-11a which can distribute | circulate a cooling water are formed in the inside. Yes. Moreover, the wiring 31 connected to the controller 5 is embed | buried under each tube 9-11. The first to third tubes 9 to 11 have the same configuration. Below, the structure of each tube 9-11 is demonstrated based on the 1st tube 9. FIG.

  As shown in FIG. 2, the wiring 31 is embedded in the upper surface of the first tube 9. Furthermore, a plurality of recesses 9 b into which the Peltier module 7 can be mounted are formed on the upper surface of the first tube 9. The recesses 9b are formed by the number of Peltier modules 7 to be attached to the first tube 9. Each recess 9b is formed with an insertion hole 9c communicating with the first inner passage 9a. The recess 9b and the insertion hole 9c correspond to openings.

  The wiring 31 has first and second connection portions 35 and 37 that are exposed from the first tube 9c in the recess 9b and are electrically connected to the first and second electrodes 27 and 29, respectively. Further, an O-ring 33 as a sealing material is provided between the insertion port 9 c and the first and second electrodes 35 and 37.

  In this heat exchanger 100 for air conditioning, as shown in FIG. 1, the 1st-3rd tubes 9-11 are provided in parallel with each other. One end side of these tubes 9 to 11 is connected to the first head 13, and the other end side of the tubes 9 to 11 is connected to the second head 14. At this time, as shown in FIG. 3, the upper surfaces of the tubes 9 to 11 are horizontal with respect to the juxtaposed direction of the tubes 9 to 11 on the vertical surface 13 b of the first head 13. It is inclined at a predetermined angle. As described above, in the heat exchanger 100 for air conditioning, the vertical surface 13b of the first head 13 is employed as a virtual vertical surface orthogonal to the flow direction of the cooling water (heat exchange medium).

  As shown in FIG. 1, a first collecting path 13 a that communicates with first to third inner passages 9 a to 11 a of first to third tubes 9 to 11 and can flow cooling water is formed inside the first head 13. Has been. In addition, a second collecting path 14a is formed inside the second head 14 so as to communicate with the first to third inner paths 9a to 11a of the third to third tubes 9 to 11 and to allow cooling water to flow therethrough. Pipes 39 and 41 are connected to the first collecting path 13a and the second collecting path 14a, respectively.

  The radiator 3 is configured so that cooling water can flow therethrough, and the cooling water can be cooled or heated by exchanging heat between the cooling water in the radiator 3 and the air around the radiator 3. It is possible. Further, a radiator fan 3 a is provided in the vicinity of the radiator 3. The radiator fan 3a is electrically connected to the battery 5a.

  The radiator 3 and the first collecting path 13a are connected by a pipe 39. The radiator 3 and the second collecting path 143a are connected by a pipe 41. Thereby, the cooling water can be circulated between the heat exchanger 100 for air conditioning and the radiator 5. The pipe 41 is provided with an electric pump P1. The electric pump P1 is electrically connected to the battery 5a. The electric pump P1 can also be provided on the pipe 39 side.

  The controller 5 functions as a control device capable of appropriately changing the strength and direction of power supplied to each Peltier element 15 and the like. Note that the configuration of the controller 5 is the same as a known one, and a detailed description of the configuration is omitted.

  In the air conditioner configured as described above, in the heat exchanger 100 for air conditioning, a plurality of Peltier modules 7 can be attached to and detached from the upper surfaces of the first to third tubes 9 to 11. Hereinafter, with reference to FIG. 2, the attaching / detaching operation of the Peltier module 7 in the first tube 9 will be specifically described.

  FIG. 2A shows a state before the Peltier module 7 is attached to the first tube 9. In this state, the second insulating substrate 23 of the Peltier element 15 is disposed in the recess 9b while the second fin 19 is inserted into the insertion hole 9c of the first tube 9. Thereby, the O-ring 33 is elastically deformed, and airtightness in the recess 9b is ensured. At the same time, the second fin 19 is placed in the first inner passage 9a. In this way, as shown in FIG. 2B, the mounting of the Peltier module 7 on the first tube 9 is completed. At this time, the recess 9 b and the insertion hole 9 c in the second tube are sealed by the Peltier module 7. For this reason, it is difficult for the cooling water flowing through the inner passage 9 a to leak out of the first tube 9. In addition, the Peltier module 7 can be removed from the first tube 9 by a procedure reverse to that at the time of mounting. The attaching / detaching operation of the Peltier module 7 to the second and third tubes 10 and 11 is the same.

  In this air conditioner heat exchanger 100, the first and second electrodes 27, 29 of each Peltier element 15 are not provided with conventional lead wires, and the wiring 31 connected to the battery 5a via the controller 5 is the first. -3 buried in tubes 9-11. If the Peltier module 7 is attached to the first to third tubes 9 to 11, the electrical connection between the first electrode 27 and the first connection part 35 and between the second electrode 29 and the second connection part 37, respectively. Connected. For this reason, in this heat exchanger 100 for air conditioning, when attaching the Peltier module 7 to the first to third tubes 9 to 11 when attaching the Peltier module 7 at the time of manufacturing or replacing the Peltier module 7, Electrical connection or removal of the Peltier element 15 and the wiring 31 can be performed simultaneously.

  Further, in the heat exchanger 100 for air conditioning, the first and second electrodes 27 and 29 of the Peltier element 15 are electrically connected to the first and second connecting portions 35 and 37 simply by attaching the Peltier module 7 when the Peltier module 7 is mounted. As a result, poor electrical connection is less likely to occur.

  In this air conditioner, as shown in FIG. 1, the controller 5 operates the electric fan 100a, the electric pump P1, and the radiator fan 3a when air-conditioning the vehicle interior. Thus, air is supplied to the air conditioning heat exchanger 100 and cooling water circulates between the air conditioning heat exchanger 100 and the radiator 3 in the direction of the arrow in FIG.

  In this state, the controller 5 controls the direction of current so that each Peltier element 15 in each Peltier module 7 absorbs heat on the one surface 15a side and dissipates heat on the other surface 15b side. Thereby, the air conditioner heat exchanger 100 functions as a cooler core, and the air around the air conditioner heat exchanger 100 is cooled by heat absorption on the one surface 15a side of the Peltier element 15. Further, the cooling water in each of the inner passages 9a to 11a is heated by heat radiation on the other surface 15b side of the Peltier element 15. Thus, the vehicle interior can be cooled by supplying the cooled air to the vehicle interior. On the other hand, the heated cooling water is cooled by exchanging heat with the air around the radiator 3 in the radiator 3.

  Further, if the controller 5 controls the direction of the current so that the Peltier element 15 in each Peltier module 7 dissipates heat on the one surface 15a side and absorbs heat on the other surface 15b side, the air conditioner heat exchanger 100 becomes the heater core. Function as. For this reason, the air around the heat exchanger 100 for air conditioning is heated by the heat radiation on the one surface 15a side of the Peltier element 15. Further, the cooling water in each of the inner passages 9a to 11a is cooled by heat absorption on the other surface 15b side of the Peltier element 15. Thus, the vehicle interior can be heated by supplying the heated air into the vehicle interior. The cooled cooling water is heated by heat exchange with the air around the radiator 3 in the radiator 3.

  In this air conditioner, in the Peltier module 7, the first and second fins 17 and 19 provided on the first insulating substrate 21 side and the second insulating substrate 23 side are used for the one surface 15 a side and the other surface 15 b side of the Peltier element 15. Each surface area is enlarged. For this reason, in this air conditioner, when performing cooling and heating, heat absorption and heat dissipation by the Peltier element 15 are efficiently performed.

  Therefore, the air-conditioning heat exchanger 100 according to the first embodiment can easily attach and detach the Peltier module 7 and can exhibit high quality. As a result, the quality of the air conditioner can be improved. .

  In the air conditioner heat exchanger 100, as shown in FIG. 2, the wiring 31 is exposed from the recess 9a of the first to third tubes 9 to 11 and is electrically connected to the first and second electrodes 27 and 29. The first and second connection portions 35 and 37 are provided. For this reason, in the heat exchanger 100 for air conditioning, the first and second connection portions 35 and 37 of the wiring 31 and the first and second electrodes 27 and 29 can be easily connected.

  Furthermore, in this heat exchanger 100 for air conditioning, as shown in FIG. 1, the 1st-3rd tubes 9-11 are provided in parallel with each other. The air conditioner heat exchanger 100 includes a first head 13 and a second head 14. For this reason, in this air conditioner heat exchanger 100, the air conditioner heat exchanger 100 is provided with more Peltier modules 7 via the first to third tubes 9 to 11, and cooling or heating by the air conditioner is further performed. It is suitably performed. Further, the inner passages 9 a to 11 a in the first to third tubes 9 to 11 communicate with each other via the first collecting passage 13 a of the first head 13 and the second collecting passage 14 a of the second head 14. For this reason, even when the first to third tubes 9 to 11 are provided, the heat exchanger 100 for air conditioning does not increase in size. For this reason, it is possible to suppress an increase in the size of the air conditioner.

  Moreover, in this heat exchanger 100 for air conditioning, as shown in FIG. 3, each Peltier module 7 is mounted in a state inclined with respect to the direction in which the tubes 9 to 11 are arranged side by side. For this reason, each Peltier module 7 is inclined with respect to the first and second heads 13 and 14 to avoid mutual interference or interference with the first to third tubes 9 to 11. For this reason, in this heat exchanger 100 for air conditioning, the attachment / detachment work of the Peltier module 7 with respect to the 1st-3rd tubes 9-11 is easy. Further, in this air conditioner, the air supply direction to the air conditioner heat exchanger 100 is adjusted so that the first fins 19 of the inclined Peltier modules 7 can be more suitably touched by air. (See arrow in FIG. 3). For this reason, it is possible to cool or heat the air more suitably during cooling or heating.

  As shown in FIG. 2, the first to third tubes 9 to 11 are provided with O-rings 33 that prevent the first and second connection portions 35 and 37 from contacting the cooling water. For this reason, it is possible to effectively prevent a short circuit from occurring between the first and second connecting portions 35 and 37 and the first and second electrodes 27 and 29 due to the cooling water.

(Example 2)
The air conditioner according to the second embodiment includes an air conditioning heat exchanger 200 shown in FIG. This air conditioner heat exchanger 200 includes first to third tubes 51 to 53 instead of the first to third tubes 9 to 11 of the air conditioner heat exchanger 100 of the first embodiment shown in FIG.

  Each upper surface of the 1st-3rd tubes 51-53 is comprised by the inclined surfaces 51d-53d inclined with respect to the vertical surface 13b of the 1st head 13, respectively, and the horizontal direction 51d-51e horizontal to the distribution direction of a cooling water. ing. Moreover, the 1st-3rd inner passages 51a-53a which can distribute | circulate a cooling water are formed in each tube 51-53. These tubes 51 to 53 are connected to the first and second heads 13 and 14 in a horizontal state with the horizontal surfaces 51e to 53e of the tubes 51 to 53, respectively.

  Each inclined surface 51d to 53d is provided with wiring, a recess, an insertion hole, and an O-ring so that the Peltier module 7 can be mounted. The wiring, the concave portion, the insertion hole, and the O-ring have the same configuration as the wiring 31, the concave portion 9b, the insertion hole 9c, and the O-ring 33 in the first embodiment, and a detailed description thereof is omitted. Other configurations are the same as those of the first embodiment.

  In the heat exchanger 200 for air conditioning, when the Peltier modules 7 are attached to the first to third tubes 51 to 53, the Peltier modules 7 are attached to the inclined surfaces 51d to 53d of the tubes 51 to 53, respectively.

For this reason, also in this heat exchanger for air conditioning 200, the attaching / detaching work of the Peltier module 7 to the first to third tubes 51 to 53 is facilitated. Moreover, also in this air conditioner, the air supply direction to the air conditioner heat exchanger 200 is adjusted so that the first fins 19 of the inclined Peltier modules 7 can be more suitably in contact with air. (Refer to the arrow in FIG. 4.) For this reason, it is possible to cool or heat the air more suitably during cooling or heating. Other functions and effects are the same as those of the first embodiment.
