PROBLEM TO BE SOLVED: To achieve space saving and reduction of the number of components in a cooling mechanism of an electric vehicle.SOLUTION: A cooling mechanism of an electric vehicle includes: an on-vehicle device (an electric motor 2) mounted on an electric vehicle; a rechargeable battery (a battery pack 3) which stores electric power for allowing the electric vehicle to travel; a case 32 which houses the rechargeable battery; a battery cooling unit 6 which supplies cooling air generated by cooling air in the case to the rechargeable battery; and a device cooling unit 5 which supplies a refrigerant which cools the on-vehicle device to the on-vehicle device. The device cooling unit has a heat exchanger 53 in which the refrigerant circulates. The heat exchanger is housed in the case, and the cooling air flows through the heat exchanger to conduct heat exchange with the refrigerant.SELECTED DRAWING: Figure 1
【課題】電動車両の冷却機構において、省スペース化および部品点数の削減を図る。【解決手段】電動車両に搭載された車載装置(電動モータ2)と、電動車両が走行するための電力を蓄電する蓄電池(電池パック3)と、蓄電池を収容するケース32と、ケース内の空気を冷却することで生成した冷却風を蓄電池に供給する電池冷却ユニット6と、車載装置を冷却する冷媒を車載装置に供給する装置冷却ユニット5とを備える。装置冷却ユニットは、内部を冷媒が循環する熱交換器53を有する。熱交換器は、ケース内に収容され、熱交換器を冷却風が流通することで冷却風と冷媒との間で熱交換させる。【選択図】 図1
