Description

本発明は、発熱体の冷却装置に関する。   The present invention relates to a cooling 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.
There is also 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、発熱体の均一な冷却、防水・防塵性能の向上、及び小型・軽量化等を実現できる発熱体の冷却装置を提供することである。   The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to provide a heating element capable of realizing uniform cooling of the heating element, improvement in waterproof and dustproof performance, and reduction in size and weight. It is to provide a cooling 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 element, 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、発熱体で発生した熱を受熱部で受熱した後、連結部を介して放熱部の放熱空間で放熱でき、発熱体を均一に冷却できる。
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・軽量化や配線抵抗の低減を実現できる。 In the first aspect of the present invention, after the heat generated by the heat generating element is received by the heat receiving part, the heat can be radiated in the heat radiating space of the heat radiating part via the connecting part, and the heat generating element can be cooled uniformly.
Moreover, 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 a reduction in size and weight and a reduction in wiring resistance can be realized.

As shown in FIGS. 1 and 2, the invention of Embodiment 1 includes a battery pack 3 having a box-shaped housing 2 that houses a battery module 1 (corresponding to a heating element in claims) and the like to be described later. It is mounted on a vehicle as a battery for supplying electricity to an electric motor (mainly a driving motor) of a hybrid vehicle.

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.
Further, outlet pipes 8 for exhausting cooling air from the outlet 2 opened in the casing 2 to the outside of the casing 2 are connected to the positions facing the inlet pipes 5 at the four corners of the casing 2. .
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、複数の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、図２に示すように、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, the housing 2 includes a plurality of battery modules 1, a heat receiving plate 10 (corresponding to a heat receiving portion in claims), and a heat pipe 11 (corresponding to a connecting portion in claims). The heat sink 12 (corresponding to the heat radiating portion of the claims) is housed in an assembled state, and the heat sink 12 is disposed in the cooling medium passage 9 as shown in FIG.

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円形断面状のヒートパイプ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の一端部を除く部分と溝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 composed of heat pipes 11a to 11c having a circular cross section 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.
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. By deforming to the outer shape, the portion excluding one end of 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から冷却媒体通路９に突出した状態で配置され、ここに後述するヒートシンク１２が図外の溶接により固定されている。
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 constituted by a tubular member having a circular cross section in which a refrigerant is sealed, and one end portion thereof is arranged in a state of projecting from the inner heat receiving plates 13 and 14 into the cooling medium passage 9, and a heat sink 12 described later is provided here. Is fixed by welding outside the figure.
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.

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、各フィン１９は、各ヒートパイプ１１ａ〜１１ｃの一端部が貫通した状態で図外の溶接により固定支持されている。   The heat sink 12 includes a plurality of (five in the first embodiment) thin plate-like fins 19 arranged at predetermined intervals along the flow of the cooling air flowing through the cooling medium passage 9, and each fin 19 The heat pipes 11a to 11c are fixedly supported by welding outside the figure in a state where one end portions thereof penetrate therethrough.

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、及びヒートシンク１２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。   In addition, in Example 1, at least each part of the heat receiving plate 10, the heat pipe 11, and the heat sink 12 is formed using a material having high thermal conductivity such as aluminum or copper.

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内に導入して冷却媒体通路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, after the cooling air is introduced into the housing 2 from the inlet 4 by the fan 6 via the inlet pipe 5 from the supply source (not shown) and passed through the cooling medium passage 9. Then, 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 cooling air discharge destination is, for example, outside the vehicle (or inside the vehicle cabin, trunk room, etc.).

そして、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。   Then, after the heat generated by the battery module 1 is generated by the heat receiving plate 10, the heat is transferred to the heat sink 12 through the heat pipe 11, and the heat is exchanged with the cooling air by the fins 19 to dissipate the heat. The battery module 1 can be cooled.

この際、前述したように、バッテリモジュール１、受熱板１０、ヒートパイプ１１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の熱を受熱板１０を介してヒートパイプ１１に効率良く伝達でき、これにより、ヒートパイプ１１は受熱板１０から受けた熱をヒートシンク１２へ効率良く移動できる。
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。 At this time, as described above, since the battery module 1, the heat receiving plate 10, and the heat pipe 11 are assembled in close contact with each other, the heat of the battery module 1 is efficiently transmitted to the heat pipe 11 through the heat receiving plate 10. Thus, the heat pipe 11 can efficiently transfer the heat received from the heat receiving plate 10 to the heat sink 12.
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 by a portion of the battery module 1 due to a temperature difference between the upstream and downstream of the cooling air or uneven distribution. The battery module 1 can be cooled uniformly, 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]
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.
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接続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 connection wiring electrically connected to each other to reduce resistance, so that the plurality of battery modules 1 are 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 reduced in size and weight.
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を冷媒による熱移動で熱的に連結するヒートパイプ１１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, and the heat transfer between the heat receiving plate 10 and the heat sink 12 by the refrigerant. Therefore, the battery module 1 can be uniformly cooled, improved in waterproof and dustproof performance, and reduced in size and weight.

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。
図７は実施例２のヒートパイプの断面形状を説明する図、図８は実施例２の受熱板とヒートパイプの固定を説明する図である。 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.
FIG. 7 is a view for explaining the cross-sectional shape of the heat pipe of the second embodiment, and FIG. 8 is a view for explaining the fixing of the heat receiving plate and the heat pipe of the second embodiment.

図７に示すように、実施例２では、実施例１で説明したヒートパイプ１１を偏平断面状にしたヒートパイプ２０を採用しているという点が実施例１と異なる。
このようなヒートパイプ１１を受熱板１０に収容する際には、実施例１と同様に、各内側受熱板13,14同士の当接面に略半長穴断面の溝21a,21bを形成しておき、図８（ａ）に示すように、内側受熱板13,14の間に、予め製造すべき外形よりも大きな外形（曲率）を有するヒートパイプ１１の母材Ｗをそれぞれ配置する。この母材Ｗの外形は楕円形でも良い。
次に、図８（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、長穴形状に重なった溝２１で母材Ｗをプレス成型して所望の外形に変形させることにより、各ヒートパイプ１１と溝２１を密着させることができるようになっている。 As shown in FIG. 7, the second embodiment is different from the first embodiment in that a heat pipe 20 in which the heat pipe 11 described in the first embodiment has a flat cross section is employed.
When such a heat pipe 11 is accommodated in the heat receiving plate 10, grooves 21a and 21b having substantially semi-long hole cross sections are formed on the contact surfaces of the inner heat receiving plates 13 and 14 as in the first embodiment. As shown in FIG. 8A, the base material W of the heat pipe 11 having an outer shape (curvature) larger than the outer shape to be manufactured in advance is arranged between the inner heat receiving plates 13 and 14, respectively. The outer shape of the base material W may be oval.
Next, as shown in FIG. 8B, the inner heat receiving plates 13 and 14 are brought into contact with each other by a press molding apparatus not shown, and the base material W is press-molded by the grooves 21 overlapped with the long hole shape. Each heat pipe 11 and the groove 21 can be brought into close contact with each other by being deformed into a desired outer shape.

従って、実施例２では、実施例１と同様の作用効果を得ることができると共に、ヒートパイプ１１を円形断面にした場合に比べて受熱面積を容易に増大でき、好適となる。   Therefore, in the second embodiment, the same operational effects as in the first embodiment can be obtained, and the heat receiving area can be easily increased as compared with the case where the heat pipe 11 has a circular cross section, which is preferable.

以上、実施例を説明してきたが、本発明は上述の実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等があっても、本発明に含まれる。

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.

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９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。
また、図１０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を効率的に冷却できる。 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. 9, the shape of the heat sink 12, for example, the direction and the number of fins 19 may be changed.
Further, as shown in FIG. 10, a cooling medium passage 9 may be formed on both sides in the housing 2, and a heat sink 12 connected to the other end of the heat pipe 11 may be provided here. The battery module 1 can be efficiently cooled.
