Title:
COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/073150
Kind Code:
A1
Abstract:
A cooling device equipped with multiple batteries (4) and a refrigeration cycle device (10). The refrigeration cycle device is formed by connecting, in a circular arrangement, a compressor (11), a cooling medium radiator (12), a decompression unit (13), and multiple evaporators (14) provided in correspondence with the multiple batteries. The cooling medium flowing through the multiple evaporators absorbs heat from the multiple batteries, thereby cooling the multiple batteries. The multiple batteries are mounted dispersed in different locations in a vehicle (2). At least one of the multiple batteries is mounted in a location where the environmental temperature when the vehicle is in use differs from that of the other batteries. The multiple evaporators are connected in series such that the cooling medium that has been decompressed by the decompression unit passes through the evaporators sequentially. In the refrigeration cycle device the cooling medium that has been decompressed by the decompression unit and changed to a gas-liquid two-phase state is circulated so as to maintain the cooling medium in the gas-liquid two-phase state until the cooling medium flows out from the evaporator farthest downstream in the refrigerant flow, that is, the evaporator (14C) which is closest to the compressor.
