たとえばハイブリッド自動車、電気自動車等の電動機駆動用バッテリー装置として、たとえばリチウムイオン二次電池などの各種の二次電池からなる複数個の小型単電池を直列または並列に接続して組電池の形態としたものが用いられている。特に、電気自動車においては航続距離の延長のニーズから組電池の大容量化が求められるので、複数の組電池が直列または並列に接続されるように組み合わされている。 For example, as a battery device for driving an electric vehicle of a hybrid vehicle, an electric vehicle, etc., a plurality of small cell cells made of various secondary batteries such as a lithium ion secondary battery are connected in series or in parallel to form an assembled battery. Things are used. In particular, in electric vehicles, since the need for extending the cruising range requires a large capacity of assembled batteries, a plurality of assembled batteries are combined so as to be connected in series or in parallel.
ところで、二次電池は、使用温度によって性能や寿命が変化するので、長時間にわたって効率良く使用するためには適正な温度で使用する必要がある。しかしながら、上述した組電池においては、各単電池間に比較的大きな温度差が生じ、その結果単電池が劣化して寿命が短くなるという問題がある。 By the way, since the performance and life of a secondary battery change depending on the operating temperature, it is necessary to use the secondary battery at an appropriate temperature in order to use it efficiently for a long period of time. However, in the above-mentioned assembled battery, there is a problem that a relatively large temperature difference occurs between the cells, and as a result, the cells deteriorate and the life is shortened.
そこで、組電池における各単電池間に生じる温度差をできるだけ小さくすることを目的として、本出願人は、先に、仕切壁を介して並列状に形成されかつ両端が開口した複数の通路を有する扁平板状のアルミニウム押出形材製冷却液流通体と、冷却液流通体における通路の長手方向の一端に、通路の並び方向に並んで設けられたアルミニウム製入口ヘッダおよび出口ヘッダと、冷却液流通体における通路の長手方向の他端に設けられたアルミニウム製中間ヘッダと、入口ヘッダに冷却液を流入させるアルミニウム製入口部材と、出口ヘッダから冷却液を流出させるアルミニウム製出口部材とを備えており、冷却液流通体の平坦な片面が発熱体取付面となり、全通路のうち冷却液流通体の片側に連続して並んで形成された複数の通路が流入側通路となるとともに、冷却液流通体の他側に連続して並んで形成された複数の残りの通路が流出側通路となり、入口ヘッダが流入側通路に通じるとともに、出口ヘッダが流出側通路に通じ、中間ヘッダが流入側通路および流出側通路に通じて両者を連通させており、入口ヘッダ、出口ヘッダおよび中間ヘッダが冷却液流通体にろう付され、入口部材が入口ヘッダにろう付され、出口部材が出口ヘッダにろう付されている液冷式冷却装置を提案した（特許文献１参照）。 Therefore, for the purpose of minimizing the temperature difference between the cells in the assembled battery, the applicant first has a plurality of passages formed in parallel through the partition wall and open at both ends.

It includes an aluminum intermediate header provided at the other end of the passage in the body in the longitudinal direction, an aluminum inlet member that allows the coolant to flow into the inlet header, and an aluminum outlet member that allows the coolant to flow out of the outlet header. , The flat one side of the coolant flower serves as the heating element mounting surface, and among all the passages, a plurality of passages formed continuously side by side on one side of the coolant flower serve as the inflow side passage and the coolant flower. A plurality of remaining passages formed continuously side by side on the other side serve as an outflow side passage, the inlet header leads to the inflow side passage, the exit header leads to the outflow side passage, and the intermediate header leads to the inflow side passage and the outflow side passage. The two are communicated through a side passage, the inlet header, outlet header and intermediate header are brazed to the coolant flower, the inlet member is brazed to the inlet header, and the outlet member is brazed to the outlet header. We have proposed a liquid-cooled cooling device (see Patent Document 1).
特許文献１記載の液冷式冷却装置の場合、冷却液流通体における通路の長手方向の一端に入口ヘッダおよび出口ヘッダが設けられているので、入口部材に冷却液を流入させる流入パイプ、および出口部材から冷却液を流出させる流出パイプを、組電池における単電池の並び方向の中間部に配置する必要がある場合、配管接続が複雑になる。したがって、種々の配管レイアウトに柔軟に対応することができない。

Then, the heated liquid hits the flow dividing control unit (28) and spreads into all the passages (16) of the passage group (19), and enters both channels (5) (10) of the heat transfer medium flower (2). After flowing in the order of the first straight part (7) (11), the turn part (9) (13) and the second straight part (8) (12), it is discharged through the outlet member (4) and the heating liquid is discharged.
