Abstract
【解決手段】電池冷却装置は、電気的に直列接続された複数個の電池モジュールをその長手方向に伸びる側面を対向させて並列配置し一体化してなるモジュール集合体1と、モジュール集合体1を収納する筐体2と、筐体2の上下面以外の面であって電池モジュールの長手方向に伸びる側面に直交する面に一体に設けられた送風部材30と、を備えている。さらに送風部材30の回転軸32の軸心高さは、対向するモジュール集合体1の上下方向両端部の高さの間に含まれている。送風部材30は、モジュール集合体1の上部表面に向けて吹き出すものであり、さらにこの吹出し風の横方向の範囲は送風部材30が対向するモジュール集合体1の略横幅にわたっている。
【選択図】図2
Description
送風部材(30)の回転軸(32)は、モジュール集合体(1)の上下方向両端部の高さの間にあり、送風部材(30)は、モジュール集合体(1)の上部表面に向けて冷却風を吹き出すものであって、冷却風の横方向の範囲は対向するモジュール集合体(1)の横方向の略全幅にわたっていることを特徴としている。
吹出口(37)は筐体(2A)内の上部に臨むとともに冷却フィン(52、53、55)と略同じ高さに設けられていることが好ましい。
吹出口(37)から吹き出された空気が冷却フィン(52、53、55)で吸熱した後、排出される排出口(26)を備え、吹出口(37)は筐体(2A)内の上部に臨むとともに、当該排出口(26)は当該吹出口(37)と向き合っている筐体面に設けられていることが好ましい。この発明によれば、吹出口から冷却フィンを介して排出口に至る通路の通風抵抗を小さくすることができるので低騒音化に寄与する。
第1実施形態の電池冷却装置は、内燃機関と電池駆動モータとを組み合わせて走行駆動源とする周知のハイブリッド自動車に用いられ、走行用モータの駆動電源等となる電池を冷却するものである。この電池は、例えばニッケル水素二次電池、リチウムイオン二次電池、有機ラジカル電池であり、筐体内に収納された状態で自動車の座席下、後部座席とトランクルームとの間の空間、運転席と助手席の間の空間などに配置されている。
第2実施形態の電池冷却装置は、第1実施形態の電池冷却装置に対して、各電極部の上に電池モジュールからの熱が伝わる冷却フィンを設けたものである。その他の構成部品については第1実施形態と同様であり、構成、作用効果においても同様である。以下に図5および図6を用いて第1実施形態と異なる点について説明する。図5は本実施形態の電池冷却装置の全体的構成と、筐体2A内に収納されたモジュール集合体1Aの構成および冷却風の流れとを示した平面図である。図6は電池冷却装置において、筐体2A内に収納されたモジュール集合体1Aの構成と冷却風の流れを示した側面図である。
ただし、Ks=比騒音(送風機自身の音)、Va=風量、ΔPa=通風抵抗
以上の本実施形態および第1実施形態の電池冷却装置によれば、上記通風抵抗ΔPaを小さくすることができるので、低騒音化を実現することができる。
第3実施形態は、第2実施形態における送風部材30の代わりに送風部材60を用いた電池冷却装置であり、これを以下に図7を用いて説明する。なお、その他の構成部品は第2実施形態と同様であり、構成、作用効果においても同様である。図7は、本実施形態の電池冷却装置の全体的構成と、筐体2A内に収納されたモジュール集合体1Aの構成および冷却風の流れとを示した平面図である。
上述の実施形態では、本発明の好ましい実施形態について説明したが、本発明は上述した実施形態に何ら制限されることなく、本発明の主旨を逸脱しない範囲において種々変形して実施することが可能である。
