Description
本発明は、基体と熱的に接続される電池を温度調節する熱媒体を流通させる流通領域を基体の内部に形成した電池用熱交換器及び車両に関する。 The present invention relates to a battery heat exchanger and a vehicle in which a circulation region in which a heat medium for adjusting the temperature of a battery thermally connected to the substrate is circulated is formed inside the substrate.
二次電池は、規定温度に保たれることにより寿命が長くなる。このため、特許文献１では、二次電池の温度調節が行われている。
特許文献１において、電池が収容されるケースには、ケース内に空気を取り込むための取込口が形成されている。ケース内には、取込口からケース内に流入した空気をケース外へ排出させる第１流路及び第２流路が形成されている。第１流路を流通する空気は、電池を介してケース外へ排出され、第２流路を流通する空気は、電池を介さずケース外に排出されるように各流路は形成されている。取込口と各流路の間には、ペルチェ素子が配設されており、ペルチェ素子の第１面により熱交換された空気は第１流路を流通し、ペルチェ素子の第２面により熱交換された空気は第２流路を流通するように構成されている。そして、電池を冷却する場合には、ペルチェ素子の第１面が空気を冷却するようにペルチェ素子が制御される。第１流路を流通する空気は、ペルチェ素子の第１面により冷却されているため、電池が冷却される。一方で、ペルチェ素子の第２面は、第２流路を流通する空気を加熱するが、第２流路を流通する空気は、電池を介さずにケース外に排出されるため、電池が加熱されることがない。同様に、電池を加熱する場合には、ペルチェ素子の第１面が空気を加熱し、ペルチェ素子の第２面が空気を冷却するようにペルチェ素子の制御が行われる。
A secondary battery has a long life by being maintained at a specified temperature. For this reason, in Patent Document 1, the temperature of the secondary battery is adjusted.
In Patent Document 1, a case in which a battery is accommodated is formed with an intake port for taking air into the case. A first flow path and a second flow path are formed in the case for discharging the air flowing into the case from the intake port to the outside of the case. Each flow path is formed so that air flowing through the first flow path is discharged out of the case via the battery, and air flowing through the second flow path is discharged out of the case without passing through the battery. . A Peltier element is disposed between the intake port and each flow path, and the air heat-exchanged by the first surface of the Peltier element flows through the first flow path and is heated by the second surface of the Peltier element. The exchanged air is configured to flow through the second flow path. When the battery is cooled, the Peltier element is controlled such that the first surface of the Peltier element cools the air. Since the air flowing through the first flow path is cooled by the first surface of the Peltier element, the battery is cooled. On the other hand, the second surface of the Peltier element heats the air flowing through the second flow path, but the air flowing through the second flow path is discharged outside the case without passing through the battery, so the battery is heated. It will not be done. Similarly, when the battery is heated, the Peltier element is controlled so that the first surface of the Peltier element heats air and the second surface of the Peltier element cools air.
ところで、効率よく電池の温度調節を行いたい場合、ペルチェ素子の第１面に熱交換器を接合するとともに電池に熱交換器を接合することにより、熱交換を促進させることがある。しかしながら、ペルチェ素子の第１面に接合される熱交換器と電池に接合される熱交換器を接続する第１流路が複雑化してしまうおそれがある。 By the way, when it is desired to efficiently control the temperature of the battery, heat exchange may be promoted by joining a heat exchanger to the first surface of the Peltier element and joining the heat exchanger to the battery. However, the first flow path connecting the heat exchanger joined to the first surface of the Peltier element and the heat exchanger joined to the battery may be complicated.
本発明は、このような従来技術の問題点に鑑みてなされたものであって、その目的は、熱媒体が流通する流路を簡素化することができる電池用熱交換器及び車両を提供することにある。 The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to provide a battery heat exchanger and a vehicle capable of simplifying a flow path through which a heat medium flows. There is.
上記課題を解決するため、請求項１に記載の発明は、基体と熱的に接続される電池を温度調節する熱媒体が流通する流通領域を前記基体の内部に形成した電池用熱交換器であって、前記基体は、前記流通領域を流通する熱媒体を加熱又は冷却する温度調節部品と熱的に接続される第１面と、前記電池と熱的に接続される第２面と、を有し、前記流通領域は、前記温度調節部品と熱交換を行うための熱媒体が流通する第１流路と、前記電池と熱交換を行うための熱媒体が流通する第２流路に分割されるとともに、前記第１流路と前記第２流路は連通していることを要旨とする。 In order to solve the above problem, the invention according to claim 1 is a battery heat exchanger in which a circulation region in which a heat medium for adjusting the temperature of a battery thermally connected to the substrate is circulated is formed inside the substrate. The base has a first surface thermally connected to a temperature control component that heats or cools a heat medium flowing through the flow region, and a second surface thermally connected to the battery. The flow region is divided into a first flow path through which a heat medium for heat exchange with the temperature control component and a second flow path through which a heat medium for heat exchange with the battery flows. In addition, the gist is that the first flow path and the second flow path communicate with each other.
これによれば、基体の内部は第１流路と第２流路に分割される。そして、第１流路を流通する熱媒体は、温度調節部品により加熱又は冷却され、第２流路に流通する。第２流路を流通する熱媒体は、電池と熱交換を行うことにより電池の温度調節を行う。流通領域には、温度調節部品により加熱又は冷却される熱媒体と、電池と熱交換を行う熱媒体の２種類の熱媒体が流通する。したがって、単一の電池用熱交換器内に第１流路及び第２流路を形成することができ、熱媒体が流通する流路を簡素化することができる。 According to this, the inside of the base is divided into the first flow path and the second flow path. And the heat medium which distribute | circulates a 1st flow path is heated or cooled by the temperature control component, and distribute | circulates to a 2nd flow path. The heat medium flowing through the second flow path adjusts the temperature of the battery by exchanging heat with the battery. Two types of heat medium, the heat medium heated or cooled by the temperature control component and the heat medium that exchanges heat with the battery, circulate in the distribution area. Therefore, a 1st flow path and a 2nd flow path can be formed in the single heat exchanger for batteries, and the flow path through which a heat carrier distribute | circulates can be simplified.
請求項２に記載の発明は、請求項１に記載の電池用熱交換器であって、前記基体は、接合されることにより前記流通領域を形成する第１基体形成部材及び第２基体形成部材とから形成され、前記第１基体形成部材と前記第２基体形成部材に挟持される流路形成部材により前記流通領域が第１流路と第２流路に分割されることを要旨とする。 Invention of Claim 2 is the battery heat exchanger of Claim 1, Comprising: The said base | substrate is joined, The 1st base | substrate formation member and the 2nd base | substrate formation member which form the said distribution | circulation area | region are joined. The flow area is divided into a first flow path and a second flow path by a flow path forming member sandwiched between the first base body forming member and the second base body forming member.
これによれば、電池用熱交換器は、第１基体形成部材と第２基体形成部材により流路形成部材を挟持するとともに、第１基体形成部材、第２基体形成部材及び流路形成部材を接合することにより形成される。したがって、電池用熱交換器を容易に製造することができる。 According to this, the battery heat exchanger holds the flow path forming member between the first base body forming member and the second base body forming member, and the first base body forming member, the second base body forming member, and the flow path forming member. It is formed by joining. Therefore, the battery heat exchanger can be easily manufactured.
請求項３に記載の発明は、請求項２に記載の電池用熱交換器であって、前記流路形成部材は、前記第１基体形成部材及び第２基体形成部材に比べて熱伝導率の低い材料からなることを要旨とする。 Invention of Claim 3 is a heat exchanger for batteries of Claim 2, Comprising: The said flow-path formation member has thermal conductivity compared with the said 1st base | substrate formation member and a 2nd base | substrate formation member. The main point is that it is made of low material.
これによれば、第１流路を流通する熱媒体と、第２流路を流通する熱媒体同士の熱交換が行われにくい。第１流路と第２流路を流通する熱媒体は、反する作用を行う熱媒体であるため、第１流路を流通する熱媒体の熱交換効率が低減されず、電池に対する温度調節の効率が低減されない。 According to this, heat exchange between the heat medium flowing through the first flow path and the heat medium flowing through the second flow path is difficult to be performed. Since the heat medium flowing through the first flow path and the second flow path is a heat medium that acts in the opposite direction, the heat exchange efficiency of the heat medium flowing through the first flow path is not reduced, and the temperature adjustment efficiency for the battery Is not reduced.
請求項４に記載の発明は、電池を動力源として走行を行う車両であって、請求項１〜請求項３のいずれか１項に記載の電池用熱交換器を搭載したことを要旨とする。
これによれば、車両に搭載される電池は、請求項１〜請求項３のいずれか１項に記載の電池用熱交換器により温度調節される。このため、車両の部品点数が削減される。
The invention according to claim 4 is a vehicle that travels using a battery as a power source, and is characterized in that the battery heat exchanger according to any one of claims 1 to 3 is mounted. .
According to this, the temperature of the battery mounted on the vehicle is adjusted by the battery heat exchanger according to any one of claims 1 to 3. For this reason, the number of parts of the vehicle is reduced.
本発明によれば、熱媒体が流通する流路を簡素化することができる。 According to the present invention, the flow path through which the heat medium flows can be simplified.

Specifically, the flow path forming member 14 has one surface (lower surface in the drawing) facing the first base forming member 12 and the other surface (upper surface in the drawing) of the flow path forming member 14. It is sandwiched between the first substrate forming member 12 and the second substrate forming member 13 so as to face the second substrate forming member 13. The circulation region S is divided into a first channel S1 and a second channel S2 by the channel forming member 14. That is, the battery heat exchanger 10 is formed by laminating the first substrate forming member 12, the second substrate forming member 13, and the flow path forming member 14.

ペルチェ素子３０、第１ポンプＰ１及び第２ポンプＰ２は、図示しない制御装置に接続されるとともに、制御装置により制御される。
次に、本実施形態における電池用熱交換器１０の作用について説明する。
The Peltier element 30, the first pump P1, and the second pump P2 are connected to a control device (not shown) and controlled by the control device.
Next, the effect | action of the heat exchanger 10 for batteries in this embodiment is demonstrated.
電池モジュール２０が使用される場合、寒冷地や冬季など、環境温度が電池モジュール２０の駆動に支障をきたすほど低いときには、電池モジュール２０の加熱が行われる。制御装置は、ペルチェ素子３０の第１面３０ａが放熱を行い、ペルチェ素子３０の第２面３０ｂが吸熱を行うようにペルチェ素子３０に電流を流す。ペルチェ素子３０の第１面３０ａが放熱を行うと、基体１１の第１面１１ａを介して第１流路Ｓ１を流通する熱媒体が加熱される。第１流路Ｓ１を流通する熱媒体は、連通路Ｓ３を介して第２流路Ｓ２に供給され、第２流路Ｓ２を流通する熱媒体は、基体１１の第２面１１ｂを介して電池モジュール２０を加熱する。 When the battery module 20 is used, the battery module 20 is heated when the environmental temperature is low enough to hinder the driving of the battery module 20 such as in a cold district or winter. The control device causes a current to flow through the Peltier element 30 such that the first surface 30a of the Peltier element 30 performs heat dissipation and the second surface 30b of the Peltier element 30 absorbs heat. When the first surface 30a of the Peltier element 30 dissipates heat, the heat medium flowing through the first flow path S1 is heated via the first surface 11a of the base 11. The heat medium flowing through the first flow path S1 is supplied to the second flow path S2 via the communication path S3, and the heat medium flowing through the second flow path S2 is connected to the battery via the second surface 11b of the base body 11. The module 20 is heated.
また、ペルチェ素子３０の第２面３０ｂが吸熱を行うと、第１熱交換器４１を流通する熱媒体は、冷却される。ペルチェ素子３０の第２面３０ｂは、第１熱交換器４１を流通する熱媒体と熱交換されることにより加熱される。そして、ペルチェ素子３０の第２面３０ｂにより冷却された熱媒体は、第２熱交換器４２を流通することにより外気と熱交換され、再度第１熱交換器４１に供給される。 When the second surface 30b of the Peltier element 30 absorbs heat, the heat medium flowing through the first heat exchanger 41 is cooled. The second surface 30 b of the Peltier element 30 is heated by heat exchange with the heat medium flowing through the first heat exchanger 41. Then, the heat medium cooled by the second surface 30 b of the Peltier element 30 is exchanged with the outside air by flowing through the second heat exchanger 42, and is supplied to the first heat exchanger 41 again.
電池モジュール２０の発熱に伴う放電性能の低下を抑止したいときには、電池モジュール２０の冷却が行われる。制御装置は、ペルチェ素子３０の第１面３０ａが吸熱を行い、ペルチェ素子３０の第２面３０ｂが放熱を行うようにペルチェ素子３０に電流を流す。ペルチェ素子３０の第１面３０ａが吸熱を行うと、基体１１の第１面１１ａを介して第１流路Ｓ１を流通する熱媒体が冷却される。第１流路Ｓ１を流通する熱媒体は、連通路Ｓ３を介して第２流路Ｓ２に供給され、第２流路Ｓ２を流通する熱媒体は、基体１１の第２面１１ｂを介して電池モジュール２０を冷却する。 The battery module 20 is cooled when it is desired to suppress a decrease in discharge performance due to the heat generation of the battery module 20. The control device passes a current through the Peltier element 30 such that the first surface 30a of the Peltier element 30 absorbs heat and the second surface 30b of the Peltier element 30 dissipates heat. When the first surface 30a of the Peltier element 30 absorbs heat, the heat medium flowing through the first flow path S1 is cooled via the first surface 11a of the base body 11. The heat medium flowing through the first flow path S1 is supplied to the second flow path S2 via the communication path S3, and the heat medium flowing through the second flow path S2 is connected to the battery via the second surface 11b of the base body 11. The module 20 is cooled.
また、ペルチェ素子３０の第２面３０ｂが放熱を行うと、第１熱交換器４１を流通する熱媒体は、加熱される。ペルチェ素子３０の第２面３０ｂは、第１熱交換器４１を流通する熱媒体と熱交換されることにより冷却される。そして、ペルチェ素子３０の第２面３０ｂにより加熱された熱媒体は、第２熱交換器４２を流通することにより外気と熱交換され、再度第１熱交換器４１に供給される。 Further, when the second surface 30b of the Peltier element 30 dissipates heat, the heat medium flowing through the first heat exchanger 41 is heated. The second surface 30 b of the Peltier element 30 is cooled by heat exchange with the heat medium flowing through the first heat exchanger 41. Then, the heat medium heated by the second surface 30 b of the Peltier element 30 is exchanged with the outside air through the second heat exchanger 42, and is supplied to the first heat exchanger 41 again.
したがって、上記実施形態によれば以下の効果を得ることができる。
（１）基体１１の内部は第１流路Ｓ１と第２流路Ｓ２に分割されていれる。そして、第１流路Ｓ１を流通する熱媒体は、ペルチェ素子３０の第１面３０ａにより加熱又は冷却され、第２流路Ｓ２に流通する。第２流路Ｓ２を流通する熱媒体は、電池モジュール２０と熱交換を行うことにより電池モジュール２０の温度調節を行う。流通領域Ｓには、ペルチェ素子３０の第１面３０ａにより加熱又は冷却される熱媒体と、電池モジュール２０と熱交換を行う熱媒体の２種類の熱媒体が流通する。したがって、単一の電池用熱交換器１０内に第１流路Ｓ１及び第２流路Ｓ２を形成することができ、熱媒体が流通する流路を簡素化することができる。
Therefore, according to the above embodiment, the following effects can be obtained.
(1) The inside of the base 11 is divided into a first flow path S1 and a second flow path S2. And the heat medium which distribute | circulates 1st flow path S1 is heated or cooled by the 1st surface 30a of the Peltier device 30, and distribute | circulates to 2nd flow path S2. The heat medium flowing through the second flow path S <b> 2 adjusts the temperature of the battery module 20 by exchanging heat with the battery module 20. Two types of heat medium, the heat medium heated or cooled by the first surface 30 a of the Peltier element 30 and the heat medium that exchanges heat with the battery module 20 circulate in the distribution area S. Therefore, the first channel S1 and the second channel S2 can be formed in the single battery heat exchanger 10, and the channel through which the heat medium flows can be simplified.
（２）基体１１の第１面１１ａにペルチェ素子３０の第１面３０ａを接合するとともに、基体１１の第２面１１ｂに電池モジュール２０を接合している。そして、第１流路Ｓ１を流通する熱媒体をペルチェ素子３０の第１面３０ａで加熱又は冷却するとともに、第２流路Ｓ２を流通する熱媒体により電池モジュール２０の温度調節を行っている。すなわち、同一の電池用熱交換器１０内を、ペルチェ素子３０の第１面３０ａで加熱又は冷却された熱媒体と、電池モジュール２０の温度調節を行う熱媒体の２種類の熱媒体が流通する。したがって、電池モジュール２０と、ペルチェ素子３０の第１面３０ａに、別々の熱交換器を接合する必要がなく、部品点数が削減される。 (2) The first surface 30 a of the Peltier element 30 is joined to the first surface 11 a of the base 11, and the battery module 20 is joined to the second surface 11 b of the base 11. And while heating or cooling the heat medium which distribute | circulates 1st flow path S1 with the 1st surface 30a of the Peltier element 30, the temperature control of the battery module 20 is performed with the heat medium which distribute | circulates 2nd flow path S2. That is, two types of heat medium, the heat medium heated or cooled by the first surface 30 a of the Peltier element 30 and the heat medium for adjusting the temperature of the battery module 20 circulate in the same battery heat exchanger 10. . Therefore, it is not necessary to join separate heat exchangers to the battery module 20 and the first surface 30a of the Peltier element 30, and the number of parts is reduced.
（３）電池用熱交換器１０は、第１基体形成部材１２と第２基体形成部材１３の接合部１２ａ，１３ａで流路形成部材１４の一面が第１基体形成部材１２と対向するとともに、他面が第２基体形成部材１３と対向するように流路形成部材１４を挟持することにより形成されている。このため、電池用熱交換器１０を容易に形成することができる。 (3) The battery heat exchanger 10 is configured such that one surface of the flow path forming member 14 faces the first substrate forming member 12 at the joint portions 12a and 13a of the first substrate forming member 12 and the second substrate forming member 13. It is formed by sandwiching the flow path forming member 14 so that the other surface faces the second substrate forming member 13. For this reason, the heat exchanger 10 for batteries can be formed easily.
（４）流路形成部材１４は、第１基体形成部材１２及び第２基体形成部材１３に比べて熱伝導率の低い材料から形成されている。このため、第１流路Ｓ１を流通する熱媒体と第２流路Ｓ２を流通する熱媒体は、互いに熱交換が行われにくい。第１流路Ｓ１を流通する熱媒体と、第２流路Ｓ２を流通する熱媒体は、反する作用を行う熱媒体である。このため、第２流路Ｓ２を流通する熱媒体の電池モジュール２０に対する温度調節効率が、第１流路Ｓ１を流通する熱媒体と熱交換されることにより低下することが抑制される。 (4) The flow path forming member 14 is formed of a material having a lower thermal conductivity than the first substrate forming member 12 and the second substrate forming member 13. For this reason, it is difficult for the heat medium flowing through the first flow path S1 and the heat medium flowing through the second flow path S2 to exchange heat with each other. The heat medium that flows through the first flow path S1 and the heat medium that flows through the second flow path S2 are heat media that perform opposite actions. For this reason, it is suppressed that the temperature control efficiency with respect to the battery module 20 of the heat medium which distribute | circulates 2nd flow path S2 is heat-exchanged with the heat medium which distribute | circulates 1st flow path S1.
（５）ペルチェ素子３０の第２面３０ｂには、第１熱交換器４１が接合されるとともに、第１熱交換器４１は、第１熱媒体流路４３により第２熱交換器４２により接合されている。このため、第１熱交換器４１を流通する熱媒体は、ペルチェ素子３０の第２面３０ｂと熱交換され、ペルチェ素子３０の第２面３０ｂと熱交換された熱媒体は、第２熱交換器４２を流通することにより外部に放熱される。ペルチェ素子３０の第１面３０ａと第２面３０ｂの温度差は、なるべく小さいことが望ましく、温度差が大きくなるにつれ、ペルチェ素子３０の熱電変換効率が低下する。ペルチェ素子３０の第１面３０ａと第２面３０ｂの温度差を小さくすることにより、効率よく電池モジュール２０の温度調節を行うことができる。 (5) The first heat exchanger 41 is joined to the second surface 30 b of the Peltier element 30, and the first heat exchanger 41 is joined by the second heat exchanger 42 through the first heat medium flow path 43. Has been. Therefore, the heat medium flowing through the first heat exchanger 41 is heat-exchanged with the second surface 30b of the Peltier element 30, and the heat medium heat-exchanged with the second surface 30b of the Peltier element 30 is second heat-exchanged. The heat is radiated to the outside through the container 42. The temperature difference between the first surface 30a and the second surface 30b of the Peltier element 30 is preferably as small as possible. As the temperature difference increases, the thermoelectric conversion efficiency of the Peltier element 30 decreases. By reducing the temperature difference between the first surface 30a and the second surface 30b of the Peltier element 30, the temperature of the battery module 20 can be adjusted efficiently.
（６）第１流路Ｓ１に第１フィン１５を配設するとともに、第２流路Ｓ２に第２フィン１６を配設している。このため、熱媒体と電池用熱交換器１０の接触面積が増加され、ペルチェ素子３０の第１面３０ａ及び電池モジュール２０と効率よく熱交換を行うことができる。 (6) The first fins 15 are disposed in the first flow path S1, and the second fins 16 are disposed in the second flow path S2. For this reason, the contact area between the heat medium and the battery heat exchanger 10 is increased, and heat exchange with the first surface 30a of the Peltier element 30 and the battery module 20 can be performed efficiently.
（７）第１フィン１５の基端１５ａは流路形成部材１４に当接するとともに、先端１５ｂは第１基体形成部材１２に当接している。同様に、第２フィン１６の基端１６ａは流路形成部材１４に当接するとともに、先端１６ｂは第２基体形成部材１３に当接している。このため、第１基体形成部材１２及び第２基体形成部材１３は、第１フィン１５及び第２フィン１６により支持され、第１基体形成部材１２、第２基体形成部材１３及び流路形成部材１４の積層方向（図中上下方向）への強度が向上されている。 (7) The base end 15 a of the first fin 15 is in contact with the flow path forming member 14, and the tip 15 b is in contact with the first base body forming member 12. Similarly, the base end 16 a of the second fin 16 is in contact with the flow path forming member 14, and the tip 16 b is in contact with the second base body forming member 13. Therefore, the first substrate forming member 12 and the second substrate forming member 13 are supported by the first fins 15 and the second fins 16, and the first substrate forming member 12, the second substrate forming member 13, and the flow path forming member 14. The strength in the stacking direction (vertical direction in the figure) is improved.
（８）供給口１７と、排出口１８は同一方向に形成されている。このため、第２熱媒体流路４４を迂回させて供給口１７と排出口１８を接続する必要がない。このため、第２熱媒体流路４４が占める領域が少なくなり、省スペース化が図られる。 (8) The supply port 17 and the discharge port 18 are formed in the same direction. For this reason, it is not necessary to bypass the second heat medium flow path 44 and connect the supply port 17 and the discharge port 18. For this reason, the area occupied by the second heat medium flow path 44 is reduced, and space saving is achieved.
（９）また、同一の電池用熱交換器１０内を、ペルチェ素子３０の第１面３０ａに加熱又は冷却される熱媒体と、電池モジュール２０の温度調節を行う熱媒体の２種類の熱媒体が流通する。このため、ペルチェ素子３０の第１面３０ａにより加熱又は冷却された熱媒体が、第２流路Ｓ２に搬送されるまでの距離が短い。したがって、ペルチェ素子３０の第１面３０ａにより加熱又は冷却された熱媒体が、第２流路Ｓ２に搬送されるまでに外気と熱交換され、電池モジュール２０に対する加熱性能又は冷却性能が低減されることが抑制される。 (9) Two types of heat medium, that is, a heat medium that is heated or cooled by the first surface 30a of the Peltier element 30 and a heat medium that adjusts the temperature of the battery module 20 in the same battery heat exchanger 10 Circulate. For this reason, the distance until the heat medium heated or cooled by the 1st surface 30a of the Peltier device 30 is conveyed by 2nd flow path S2 is short. Therefore, the heat medium heated or cooled by the first surface 30a of the Peltier element 30 is heat-exchanged with the outside air before being transferred to the second flow path S2, and the heating performance or cooling performance for the battery module 20 is reduced. It is suppressed.
（１０）基体１１の第１面１１ａにペルチェ素子３０の第１面３０ａを接合するとともに、基体１１の第２面１１ｂに電池モジュール２０を接合している。このため、流路などを介して電池用熱交換器１０、ペルチェ素子３０及び電池モジュール２０を接続する必要がなく、電池用熱交換器１０、ペルチェ素子３０、電池モジュールの２０一体形成が可能となる。 (10) The first surface 30 a of the Peltier element 30 is joined to the first surface 11 a of the base 11, and the battery module 20 is joined to the second surface 11 b of the base 11. For this reason, it is not necessary to connect the battery heat exchanger 10, the Peltier element 30, and the battery module 20 via a flow path or the like, and the battery heat exchanger 10, the Peltier element 30, and the battery module 20 can be integrally formed. Become.
