PROBLEM TO BE SOLVED: To enhance the cooling performance of a battery cell by the increase of heat exchange quantity between cooling air and the battery cell, when a cooling passage for making a cooling air flow is disposed outside a battery module.SOLUTION: A cooling passage S through which the cooling air flows to cool a battery cell 21 is formed in section outside a battery module 20. On the internal surface of the cooling passage S, there is provided a salient 34A for generating a turbulent flow in a manner to protrude toward the inside of the cooling passage S and extend to a direction intersecting with the cooling air flow that flows through the cooling passage S.SELECTED DRAWING: Figure 1
【課題】バッテリモジュールの外部に冷却風が流れる冷却通路を設ける場合に、冷却風とバッテリセルとの熱交換量を増大させてバッテリセルの冷却性能を高める。【解決手段】バッテリモジュール20の外部には、バッテリセル21を冷却するための冷却風が流れる冷却通路Sが区画形成されている。冷却通路Sの内面には、冷却通路S内へ向けて突出し、かつ、冷却通路Sを流れる冷却風の流れと交差する方向に延びる乱流発生用凸部34Aが設けられている。【選択図】図1
