To provide a vehicle cooling mechanism which can cool radiators properly.SOLUTION: A cooling mechanism 70 includes: a first radiator 73 for cooling a battery 60 of a vehicle 1; a second radiator 74 for cooling a PCU 32 which converts electric power supplied from the battery 60 and electric power to be supplied to the battery 60; and a wind guide duct part 75 which guides outer air from an opening 7 provided at a front end part of the vehicle 1 to the first radiator 73 and the second radiator 74. The first radiator 73 is disposed above the second radiator 74. At least a part of the second radiator is disposed so as to overlap with the opening 7 when viewed from the front of the vehicle 1, an upper end part 74u of the second radiator 74 is located above an upper end part 7u of the opening 7, and a lower end part 74d of the second radiator 74 is located below the upper end part 7u of the opening 7.SELECTED DRAWING: Figure 4

    【課題】複数のラジエータを適切に冷却することができる車両用冷却機構を提供する。【解決手段】冷却機構70は、車両1のバッテリ60を冷却するための第1ラジエータ73と、バッテリ60から供給される電力及びバッテリ60に供給する電力を変換するPCU32を冷却するための第2ラジエータ74と、車両1の前端部に設けられる開口部7から外気を第1ラジエータ73及び第2ラジエータ74に導く導風ダクト部75と、を備える。第1ラジエータ73は、第2ラジエータ74の上方に配置される。第2ラジエータの少なくとも一部は、車両1の前方から見て、開口部7とオーバーラップするように配置され、第2ラジエータ74の上端部74uは開口部7の上端部7uよりも上方に位置し、第2ラジエータ74の下端部74dは、開口部7の上端部7uよりも下方に位置する。【選択図】図4
