To suppress occurrence of variation in temperature of a battery pack in a cooling device for a battery pack having a plurality of intake ports and intake passages.SOLUTION: A first intake passage 33a through which the cooling air introduced from a first intake port 30a flows and a second intake passage 33b through which the cooling air introduced from a second intake port 30b flows are arranged adjacently. A plurality of first orifices 35 are formed between the first intake passage 33a and a confluent part 40, and a plurality of second orifices 36 are formed between the second intake passage 33b and the confluent part 40. A battery pack 10 is cooled by the cooling air flowing out of each orifice.SELECTED DRAWING: Figure 1

    【課題】複数の吸気口および吸気通路を備えた組電池の冷却装置において、組電池の温度にばらつきが発生することを抑制する。【解決手段】第1吸気口30aから導入した冷却風が流れる第1吸気通路33aと第1吸気口30bから導入した冷却風が流れる第2吸気通路33bを隣接して配置し、第1吸気通路33aと合流部40の間に複数の第1オリフィス35を形成するとともに第2吸気通路33bと合流部40の間に複数の第2オリフィス36を形成し、各オリフィスから流出した冷却風で組電池10を冷却する。【選択図】図1
