Abstract: A battery provided in a vehicle and configured to supply electric power is cooled down by coolant the heat of which is exchanged with the heat of external air by a radiator. The radiator is provided near the battery and performs heat-exchange between the coolant and the external air taken in through introduction holes provided on a bottom face of the vehicle. Thus, even in a case where the radiator is provided in a vehicle floor portion so that the battery is upsized, it is possible to restrain a coolant pipe from being elongated. This accordingly makes it possible to improve mountability to the vehicle.
