Kind Code:
B2
Abstract:
This battery cooling device is provided with: a compressor (11); a radiator (12); a first decompression unit (14b) and a second decompression unit (14c) which are arranged in parallel to each other with respect to the flow of a refrigerant, which has radiated heat in the radiator (12), and which adjust the decompression amount of the refrigerant by adjusting the opening surface area of the flow path through which the refrigerant flows; an air cooler (18) which exchanges heat between the refrigerant decompressed by the first decompression unit (14b) and air blown into of the vehicle cabin, to evaporate the refrigerant and cool the air; a battery cooler (21) which cools a battery by evaporating refrigerant decompressed by the second decompression unit (14c); and a control unit (50) which controls the opening area of the first decompression unit (14b) and the second decompression unit (14c). If the air cooler (18) is in a frosted state, the control unit (50) closes only the first decompression unit (14b), and if the battery cooler (21) is in a frosted state, closes only the second decompression unit (14c).
