Description

本発明は、発熱体の温度調整装置に関する。   The present invention relates to a temperature adjusting device for a heating element.

従来、発熱体としての複数のバッテリモジュールの間に冷却風を通過させて各バッテリモジュールを冷却するようにした技術が公知になっている（特許文献１参照）。
特開２００７−１７２９８２号公報 Conventionally, a technique in which cooling air is passed between a plurality of battery modules as heating elements to cool each battery module is known (see Patent Document 1).
JP 2007-172982 A

しかしながら、従来の発明にあっては、複数のバッテリモジュール間に冷却風を通過させて各バッテリモジュールを直接冷却していたため、バッテリモジュール間に流入する冷却風の流量も異なる上、バッテリモジュール間を流れる冷却風の温度はその上流側と下流側で異なるため、バッテリモジュールの部位によって温度差が生じ、バッテリ残量を有効に活用できず、寿命の悪化にも繋がるという問題点があった。
また、バッテリモジュール間の防水・防塵性能能が低いという問題点があった。
さらに、バッテリモジュール間に冷却風を流すための空間が必要になり、バッテリの大型化や接続配線の延長による抵抗の増大を招くという問題点があった。 However, in the conventional invention, since the cooling air is directly passed between the plurality of battery modules to directly cool the battery modules, the flow rate of the cooling air flowing between the battery modules is different, and the battery modules Since the temperature of the flowing cooling air is different between the upstream side and the downstream side, there is a problem that a temperature difference occurs depending on the part of the battery module, the remaining battery capacity cannot be effectively used, and the life is also deteriorated.
In addition, there is a problem that the waterproof / dustproof performance between the battery modules is low.
Furthermore, a space for flowing cooling air between the battery modules is required, and there is a problem in that the battery is increased in size and the resistance is increased due to the extension of the connection wiring.

本発明は上記課題を解決するためになされたものであって、その目的とするところは、発熱体の均一な温度調整、防水・防塵性能の向上、及び小型・軽量化等を同時に実現できる発熱体の温度調整装置を提供することである。   The present invention has been made in order to solve the above-mentioned problems, and the object of the present invention is to generate heat that can simultaneously achieve uniform temperature adjustment of the heating element, improvement of waterproof and dustproof performance, and reduction in size and weight. It is to provide a body temperature regulating device.

請求項１記載の発明では、放熱空間に配置される放熱部と、発熱体と密着した状態で設けられる受熱部と、上記受熱部と放熱部を冷媒による熱移動で熱的に連結する連結部を備えることを特徴とする。   In the first aspect of the present invention, the heat radiating portion disposed in the heat radiating space, the heat receiving portion provided in close contact with the heat generating body, and the connecting portion that thermally connects the heat receiving portion and the heat radiating portion by heat transfer by the refrigerant. It is characterized by providing.

請求項１の発明では、第１連結部を介して発熱体と放熱部との間で熱を移動でき、発熱体を均一に温度調整できる。
また、受熱部は発熱体に密着した状態で設けられるため、防水・防塵性能能を向上できる。
さらに、発熱体を電気的に接続した複数のモジュールとした場合に各モジュール間に冷却媒体を流通させるための空間を形成する必要がなく、小型・軽量化等や配線抵抗の低減を実現できる。 In invention of Claim 1, heat can be moved between a heat generating body and a thermal radiation part via a 1st connection part, and a heat generating body can be temperature-controlled uniformly.
In addition, since the heat receiving portion is provided in close contact with the heating element, the waterproof / dustproof performance can be improved.
Further, when a plurality of modules in which the heating elements are electrically connected are formed, it is not necessary to form a space for circulating the cooling medium between the modules, and it is possible to realize a reduction in size and weight and a reduction in wiring resistance.

筐体２の四隅の一角に相当する部位には、筐体２に開口された導入口４から冷却風（請求項の冷却媒体に相当）を筐体２内に導入するための入口パイプ５が連通接続される他、この入口パイプ５の途中には冷却風を筐体２内へ送出するためのファン６が設けられている。
また、筐体２の四隅の入口パイプ５と対向する位置には、筐体２に開口された排出口７から後述するバッテリモジュール１を冷却後の冷却風を筐体２外へ排出するための出口パイプ８が連通接続されている。
これにより、筐体２内には、図２中一点鎖線矢印で示す冷却風が導入口４から排出口７へ向かう冷却媒体通路９（請求項の放熱空間に相当）が形成されている。 An inlet pipe 5 for introducing cooling air (corresponding to a cooling medium in claims) into the housing 2 from an inlet 4 opened in the housing 2 is provided at a portion corresponding to one corner of the housing 2. Besides being connected in communication, a fan 6 for sending cooling air into the housing 2 is provided in the middle of the inlet pipe 5.

As a result, a cooling medium passage 9 (corresponding to a heat radiation space in the claims) in which the cooling air indicated by a one-dot chain line arrow in FIG. 2 moves from the inlet 4 to the outlet 7 is formed in the housing 2.

図３、４に示すように、筐体２内には、バッテリモジュール１と、受熱板１０（請求項の受熱部に相当）と、ヒートパイプ１１（請求項の第２連結部に相当）と、熱電素子部材２０（請求項の第１連結部に相当）と、ヒートシンク１２（請求項の放熱部に相当）とが組み付けられた状態で収容される他、ヒートシンク１２は前述した冷却媒体通路９に配置されている。   As shown in FIGS. 3 and 4, a battery module 1, a heat receiving plate 10 (corresponding to a heat receiving part in claims), and a heat pipe 11 (corresponding to a second connecting part in claims) are included in the housing 2. The thermoelectric element member 20 (corresponding to the first connecting part in the claims) and the heat sink 12 (corresponding to the heat dissipating part in the claims) are housed in an assembled state, and the heat sink 12 is connected to the cooling medium passage 9 described above. Is arranged.

バッテリモジュール１は、図示を省略する車両の電動機（主に走行用モータ）に電気を供給するためのものであって、公知のように、繰り返し充放電が可能なニッケルカドミウム電池、ニッケル水素電池、またはリチウムイオン電池等の二次電池が採用されている。
また、バッテリモジュール１は、冷却媒体通路９の長手方向と直交する方向へ長い長尺の板状に形成される他、図５に示すように、後述する受熱板１０によって縦３個×横２個に並べられた状態で組み付けられたバッテリモジュール１ａ〜１ｆで構成されている。
また、図２に示すように、各バッテリモジュール１ａ〜１ｆ同士は、筐体２との隙間Ｈ１に配設された図示を省略する接続配線により、互いに電気的に直列または並列に接続されている。 The battery module 1 is for supplying electricity to a vehicle electric motor (mainly a traveling motor) (not shown). As is well known, a nickel cadmium battery, a nickel hydrogen battery, Alternatively, a secondary battery such as a lithium ion battery is employed.
Further, the battery module 1 is formed in a long plate shape that is long in a direction orthogonal to the longitudinal direction of the cooling medium passage 9, and as shown in FIG. The battery modules 1a to 1f are assembled in a state of being arranged in pieces.
Further, as shown in FIG. 2, the battery modules 1 a to 1 f are electrically connected in series or in parallel to each other by connection wiring (not shown) disposed in the gap H <b> 1 with the housing 2. .

図５に示すように、受熱板１０は、互いに接合され、且つ、バッテリモジュール１ａ〜１ｆの内側にそれぞれ密着した状態で組み付けられた２枚の板状の内側受熱板13,14（請求項の分割部に相当）と、バッテリモジュール１ａ〜１ｆの外側に組み付けられた外側受熱板15,16で構成されている。
また、受熱板１１〜１４には、その厚み方向に凹設された溝１７が各受熱板１１〜１４の長手方向の全長に亘って形成されると共に、各溝１７にそれぞれ対応するバッテリモジュール１ａ〜１ｆの各部が嵌合した状態で組み付けられている。
従って、各バッテリモジュール１ａ〜１ｆ同士間とそれらの外周部は受熱板１０によって略覆われた状態となっている。
なお、実施例１では、バッテリモジュール１ａ〜１ｆと外側受熱板15,16の溝１７との間には矩形状の隙間Ｈ２が貫通形成されているが、この限りではない。 As shown in FIG. 5, the heat receiving plate 10 is joined to each other, and two plate-like inner heat receiving plates 13 and 14 assembled in close contact with the inside of each of the battery modules 1a to 1f. And the outer heat receiving plates 15 and 16 assembled outside the battery modules 1a to 1f.
Further, the heat receiving plates 11 to 14 are provided with grooves 17 recessed in the thickness direction over the entire length in the longitudinal direction of the heat receiving plates 11 to 14, and the battery modules 1 a respectively corresponding to the grooves 17. It is assembled in a state in which each part of ˜1f is fitted.
Therefore, between each battery module 1a-1f and those outer peripheral parts are the states substantially covered with the heat receiving plate 10. FIG.
In the first embodiment, a rectangular gap H2 is formed between the battery modules 1a to 1f and the grooves 17 of the outer heat receiving plates 15 and 16, but this is not restrictive.

ヒートパイプ１１は、内側受熱板13,14の内部、詳細には各バッテリモジュール１ａ〜１ｆの幅方向中央位置にそれぞれ収容されたヒートパイプ１１ａ〜１１ｃで構成されている。
具体的には、図４に示すように、内側受熱板13,14同士の接合面には、各ヒートパイプ１１ａ〜１１ｃを収容するための半円形断面の溝18a,18bが内側受熱板13,14の長手方向の全長に亘ってそれぞれ形成されており、各ヒートパイプ１１ａ〜１１ｃを収容する際には、先ず、図６（ａ）に示すように、内側受熱板13,14の間に、予め製造すべき外径よりも僅かに大きな外径を有するヒートパイプ１１の母材Ｗをそれぞれ配置する。
次に、図６（ｂ）に示すように、図外のプレス用成形装置で内側受熱板13,14を当接させて、円形状に重なった溝１８で母材Ｗをプレス成形して所望の外形に変形させることにより、ヒートパイプ１１と溝１７を密着させることができるようになっている。
なお、その後、少なくとも内側受熱板13,14同士は図外の溶接または固定部材等により接合される。 The heat pipe 11 is configured by heat pipes 11a to 11c housed inside the inner heat receiving plates 13 and 14, specifically, at the center positions in the width direction of the battery modules 1a to 1f, respectively.
Specifically, as shown in FIG. 4, semi-circular grooves 18 a and 18 b for accommodating the heat pipes 11 a to 11 c are formed on the inner heat receiving plates 13 and 14 on the joint surfaces of the inner heat receiving plates 13 and 14. 14 is formed over the entire length in the longitudinal direction, and when the heat pipes 11a to 11c are accommodated, first, as shown in FIG. 6 (a), between the inner heat receiving plates 13 and 14, A base material W of the heat pipe 11 having an outer diameter slightly larger than the outer diameter to be manufactured in advance is arranged.
Next, as shown in FIG. 6B, the inner heat receiving plates 13 and 14 are brought into contact with each other by a pressing molding apparatus not shown in the figure, and the base material W is press-molded with the circular grooves 18 to be desired. The heat pipe 11 and the groove 17 can be brought into close contact with each other.
After that, at least the inner heat receiving plates 13 and 14 are joined together by welding or a fixing member not shown.

ヒートパイプ１１は、冷媒が封入された円形断面の管状部材で構成されており、その一端部は、内側受熱板13,14の端面と当接した平板状の受熱板２１に図外の溶接で固定されている。
ヒートパイプ１１は、公知のようにサイホンと同様の動作原理で作動する。
実施例１では、内側受熱板13,14と密着した加熱部で冷媒の蒸発が生じ、冷媒の蒸気がヒートシンク１２側の冷却部に移動して凝縮し、ここで、蒸発潜熱の受け渡しが行われる。
その後、凝縮した冷媒はヒートパイプ１１内に設けられた図示を省略するウィックの毛細管作用で加熱部へ再び戻ることにより、加熱部から冷却部への熱の移動が行われるようになっている。 The heat pipe 11 is composed of a tubular member having a circular cross section in which a refrigerant is sealed, and one end of the heat pipe 11 is welded to a flat heat receiving plate 21 in contact with the end surfaces of the inner heat receiving plates 13 and 14 by welding not shown. It is fixed.
As is well known, the heat pipe 11 operates on the same operating principle as a siphon.
In the first embodiment, the refrigerant evaporates in the heating unit that is in close contact with the inner heat receiving plates 13 and 14, and the vapor of the refrigerant moves to the cooling unit on the heat sink 12 side and condenses, where the latent heat of evaporation is transferred. .
Thereafter, the condensed refrigerant is returned to the heating unit by the capillary action of a wick (not shown) provided in the heat pipe 11 so that heat is transferred from the heating unit to the cooling unit.

さらに、受熱板２１は、各ヒートパイプ１１の接続位置に対応して設けられた３つの熱電素子部材２０を介してヒートシンク１２に連結されている。
熱電素子部材２０は、熱電素子（所謂ペルチェ素子）等が収容された箱状の容器で構成されており、その一方側側面は受熱板２１に密着した状態で図外の溶接または固定部材等で固定される一方、他方側側面はヒートシンクの基部１２ａに密着した状態で図外の溶接または固定部材等で固定されている。 Further, the heat receiving plate 21 is connected to the heat sink 12 via three thermoelectric element members 20 provided corresponding to the connection positions of the heat pipes 11.
The thermoelectric element member 20 is constituted by a box-shaped container in which a thermoelectric element (so-called Peltier element) or the like is accommodated, and one side surface thereof is in close contact with the heat receiving plate 21 by welding or a fixing member not shown. On the other hand, the other side surface is fixed by welding or a fixing member or the like not shown in the state in close contact with the base 12a of the heat sink.

熱電素子部材２０は、公知のようにペルチェ作用と同様の動作原理で作動する。
実施例１では、図２の拡大図に示すように、内面が対向している２つの基板20a,20bに電極を介して接合されたｐ型及びｎ型の半導体２０ｃ（請求項の熱電素子に相当）がπの字形に交互に連結され、この半導体２０ｃに図中矢印で示す所定方向へ直流電流を流すことにより、受熱板２１側からヒートシンク１２側へ熱を移動させて、受熱板２１と当接した一方側側面で吸熱（冷却）させ、ヒートシンク１２の基部１２ａが当接した他方側側面側で発熱（放熱）させることができるようになっている。 As is known, the thermoelectric element member 20 operates on the same operating principle as the Peltier action.
In the first embodiment, as shown in the enlarged view of FIG. 2, p-type and n-type semiconductors 20c joined to two substrates 20a and 20b whose inner surfaces face each other via electrodes ( Equivalent) are alternately connected in the shape of π, and by flowing a direct current through the semiconductor 20c in a predetermined direction indicated by an arrow in the figure, heat is transferred from the heat receiving plate 21 side to the heat sink 12 side, and the heat receiving plate 21 and Heat can be absorbed (cooled) on the one side surface that is in contact, and heat can be generated (heat radiation) on the other side surface on which the base 12a of the heat sink 12 is in contact.

ヒートシンク１２は、冷却媒体通路９を流れる冷却風の流れに沿って所定間隔で配置された複数（実施例１では５枚）の薄板状のフィン１９で構成される他、その基端側が前述した板状の基部１２ａに立設した状態で設けられている。   The heat sink 12 is composed of a plurality (five in the first embodiment) of thin plate-like fins 19 arranged at predetermined intervals along the flow of the cooling air flowing through the cooling medium passage 9, and the base end side thereof is described above. It is provided in a state of standing on the plate-like base portion 12a.

その他、実施例１では、少なくとも受熱板１０、ヒートパイプ１１、ヒートシンク１２、及び熱電素子部材２０の各部はアルミや銅等の熱伝導性が高い素材を用いて形成されている。
また、ヒートパイプ１１は省略することもできる。 In addition, in Example 1, at least each part of the heat receiving plate 10, the heat pipe 11, the heat sink 12, and the thermoelectric element member 20 is formed using a material having high thermal conductivity such as aluminum or copper.
Further, the heat pipe 11 can be omitted.

次に、作用を説明する。   Next, the operation will be described.

［バッテリモジュールの冷却について］
このように構成されたバッテリパック３では、冷却風を図外の供給元から入口パイプ５を介してファン６で導入口４から筐体２内に導入した後、冷却媒体通路９を通過させた後、排出口７から出口パイプ８を介して筐体２外の図外の排出先へ排出する。 [Battery module cooling]
In the battery pack 3 configured as described above, the cooling air is introduced from the inlet 4 into the housing 2 by the fan 6 via the inlet pipe 5 from the supply source (not shown), and then passed through the cooling medium passage 9. After that, it is discharged from the discharge port 7 through the outlet pipe 8 to a discharge destination outside the housing 2 outside the figure.

なお、冷却風の供給元は、例えば、車室内空調用のエアコンの風（または車室内空気）が用いられ、バッテリモジュール１の温度に応じて冷却風の温度とファン６による導入量を調整できるようにする。なお、バッテリモジュール１の温度はその発熱量により算出できる。
一方、冷却風の排出先は、例えば、車外（または車室内、トランクルーム等とする。 The supply source of the cooling air is, for example, the air conditioning air conditioning for the vehicle interior air conditioning (or vehicle interior air), and the temperature of the cooling air and the amount of introduction by the fan 6 can be adjusted according to the temperature of the battery module 1. Like that. The temperature of the battery module 1 can be calculated from the amount of heat generated.
On the other hand, the discharge destination of the cooling air is, for example, outside the vehicle (or in the passenger compartment or trunk room).

そして、熱電素子部材２０に通電して、各バッテリモジュール１が発熱して発生した熱を、受熱板１０で受熱させた後、ヒートパイプ１１及び熱電素子部材２０を介してヒートシンク１２に移動させると共に、フィン１９で冷却風と熱交換させて放熱させることにより、バッテリモジュール１を冷却できる。
この際、前述したように、各バッテリモジュール１、受熱板１０、ヒートパイプ１１、熱電素子部材２０（受熱板２１共）、ヒートシンク１１の基部１２ａは互いに密着した状態で組み付けられているため、バッテリモジュール１の熱をヒートパイプ１１及び受熱板２１を介して熱電素子部材２０に効率良く伝達でき、バッテリモジュール１を効率良く冷却できる。
また、ヒートシンク１２のフィン１９を冷却風の流れ方向に沿って配置しているため、冷却風を冷却媒体通路９にスムーズに流して放熱効果を促進できる。 Then, after the thermoelectric element member 20 is energized and the heat generated by each battery module 1 is generated by the heat receiving plate 10, it is moved to the heat sink 12 via the heat pipe 11 and the thermoelectric element member 20. The battery module 1 can be cooled by causing the fins 19 to exchange heat with the cooling air to dissipate heat.
At this time, as described above, each battery module 1, the heat receiving plate 10, the heat pipe 11, the thermoelectric element member 20 (both of the heat receiving plate 21), and the base 12a of the heat sink 11 are assembled in close contact with each other. The heat of the module 1 can be efficiently transmitted to the thermoelectric element member 20 via the heat pipe 11 and the heat receiving plate 21, and the battery module 1 can be efficiently cooled.
Further, since the fins 19 of the heat sink 12 are arranged along the flow direction of the cooling air, the cooling air can flow smoothly through the cooling medium passage 9 to promote the heat dissipation effect.

従って、冷却風を各バッテリモジュール１ａ〜１ｆ間に通過させて冷却する場合に比べて、冷却風の上下流の温度差や不均一な流通によってバッテリモジュール１の部位によって温度差が生じる虞がなく、バッテリモジュール１を均一に冷却でき、バッテリモジュール１の残量を有効に活用できると同時に長寿命化を実現できる。   Therefore, compared with the case where the cooling air is cooled by passing between the battery modules 1a to 1f, there is no possibility that a temperature difference is caused depending on the part of the battery module 1 due to the temperature difference between the upstream and downstream of the cooling air or uneven distribution. The battery module 1 can be uniformly cooled, the remaining amount of the battery module 1 can be effectively utilized, and at the same time, the life can be extended.

［防水性・防塵性能について］
また、実施例１では、前述したように、各バッテリモジュール１ａ〜１ｆ間に冷却風が通過しない上、各バッテリモジュール１ａ〜１ｆは受熱板１０で略覆われた状態で組み付けられるため、防水性・防塵性能に優れる。
加えて、ファン６のモータは通常、各バッテリモジュール１ａ〜１ｆ間の摩耗粉の詰まりを防止するために、摩耗粉の発生が少ないブラシレスモータを採用することが多いが、実施例１では、ブラシ付きモータを採用することも可能となる。 [Waterproof and dustproof performance]
Further, in the first embodiment, as described above, since the cooling air does not pass between the battery modules 1a to 1f and the battery modules 1a to 1f are assembled in a state of being substantially covered with the heat receiving plate 10, the waterproof performance is ensured.・ Excellent dustproof performance.
In addition, the motor of the fan 6 usually employs a brushless motor that generates less wear powder in order to prevent clogging of wear powder between the battery modules 1a to 1f. It is also possible to employ a motor with an attachment.

［受熱板の治具化とバッテリモジュールの小型・軽量化について］
また、実施例１では、前述したように、各バッテリモジュール１（ヒートパイプ１１共）を組み付けるための治具として受熱板１０を兼用できる。
また、各バッテリモジュール１は互いに電気的に接続する配線を短くして抵抗を少なくしたいという要求があるため、複数のバッテリモジュール１を共用の受熱板１０で近接した状態で正確・容易に位置決め・組み付けできると同時に、小型・軽量化を実現できる。
また、受熱板１０を各バッテリモジュール１で共用させることになり、受熱板１０を介して全てのヒートパイプ１１に熱を伝達でき、好適となる。
さらに、実施例１では入口パイプ５及び出口パイプ８を筐体２の一方側に配置しているため、筐体２の両側に分けて配置した場合に比べて、バッテリパック３を小型化できる。 [Changing the heat receiving plate to a jig and reducing the size and weight of the battery module]
In the first embodiment, as described above, the heat receiving plate 10 can also be used as a jig for assembling the battery modules 1 (both of the heat pipes 11).
In addition, each battery module 1 is required to shorten the wiring electrically connected to each other to reduce resistance, so that the plurality of battery modules 1 can be positioned accurately and easily in a state of being close to each other by the common heat receiving plate 10. It can be assembled and at the same time can be made smaller and lighter.
Further, the heat receiving plate 10 is shared by the battery modules 1, and heat can be transmitted to all the heat pipes 11 through the heat receiving plate 10, which is preferable.
Furthermore, since the inlet pipe 5 and the outlet pipe 8 are disposed on one side of the housing 2 in the first embodiment, the battery pack 3 can be reduced in size compared to the case where the inlet pipe 5 and the outlet pipe 8 are disposed separately on both sides of the housing 2.

次に、効果を説明する。
以上、説明したように、実施例１では、冷却媒体通路９に配置されるヒートシンク１２と、バッテリモジュール１と密着した状態で設けられる受熱板１０と、受熱板１０とヒートシンク１２を半導体２０ｃによる熱移動で熱的に連結する熱電素子部材２０を備えるため、バッテリモジュール１の均一な冷却、防水・防塵性能の向上、及び小型・軽量化等を同時に実現できる。 Next, the effect will be described.
As described above, in the first embodiment, the heat sink 12 disposed in the cooling medium passage 9, the heat receiving plate 10 provided in close contact with the battery module 1, the heat receiving plate 10 and the heat sink 12 are heated by the semiconductor 20c. Since the thermoelectric element member 20 that is thermally connected by movement is provided, uniform cooling of the battery module 1, improvement in waterproof / dustproof performance, and reduction in size and weight can be realized at the same time.

以下、実施例２を説明する。
実施例２において、上記実施例１と同様の構成部材については同じ符号を付してその説明は省略し、相違点のみ詳述する。 Example 2 will be described below.
In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, the description thereof will be omitted, and only the differences will be described in detail.

バッテリモジュール１の低温時には、内部抵抗が高くなって放電出力が低下してしまうため、バッテリの作動初期には速やかに常温になるように加熱することが望ましい。
そこで、実施例２では、バッテリモジュール１の低温時には、半導体２０ｃの直流電流を実施例１の所定の方向とは反対方向に流して、ヒートシンク１２側から受熱板２１側へ熱を移動させて、受熱板２１に当接した一方側側面で発熱（放熱）させ、ヒートシンク１２の基部１２ａに当接した他方側側面側で吸熱（冷却）させることにより、バッテリモジュール１を暖めることができる。
なお、この際、冷却媒体通路９には車室内空調用エアコンの温風を流すようにしても良い。 When the battery module 1 is at a low temperature, the internal resistance increases and the discharge output decreases. Therefore, it is desirable to quickly heat the battery module 1 to normal temperature at the initial stage of operation of the battery.
Therefore, in the second embodiment, when the battery module 1 is at a low temperature, a direct current of the semiconductor 20c is caused to flow in a direction opposite to the predetermined direction of the first embodiment, and heat is transferred from the heat sink 12 side to the heat receiving plate 21 side. The battery module 1 can be warmed by generating heat (dissipating heat) on one side surface in contact with the heat receiving plate 21 and absorbing heat (cooling) on the other side surface in contact with the base 12 a of the heat sink 12.
At this time, the warm air of the air conditioner for vehicle interior air conditioning may flow through the cooling medium passage 9.

従って、バッテリモジュール１の低温時に、バッテリモジュール１を加熱でき、放電出力が低下してしまうのを防止できる。   Therefore, when the battery module 1 is at a low temperature, the battery module 1 can be heated and the discharge output can be prevented from decreasing.

For example, in Example 1, although the example which applied the heat generating body to the battery module 1 was demonstrated, you may apply to the inverter circuit etc. of a motor for driving | running | working.
Further, the heat pipe only needs to circulate the refrigerant inside so as to be able to absorb and dissipate heat, and may have another structure that circulates inside without using the wick capillary action.
Similarly, the thermoelectric element member only needs to have different heat absorption and heat dissipation, and may be other than Peltier.

また、実施例１で説明した各構成部材の詳細な部位の形状、形成数、配置、固定方法、素材等は適宜設定できる。
例えば、図７に示すように、偏平断面状のヒートパイプ３０を採用しても良い。
また、図８に示すように、ヒートシンク１２の形状、例えばフィン１９の向きや枚数を変えたものを採用しても良い。
さらに、図９に示すように、筐体２内の両側に冷却媒体通路９を形成して、ここにヒートパイプ１１の他端部に連結された熱電素子部材２０（受熱板２１共）及びヒートシンク１２を設けても良く、この場合、さらにバッテリモジュール１を効率的に温度調整できる。 Moreover, the shape of the detailed site | part of each structural member demonstrated in Example 1, the number of formation, arrangement | positioning, the fixing method, a raw material, etc. can be set suitably.
For example, as shown in FIG. 7, a heat pipe 30 having a flat cross section may be employed.
