COOLING DEVICE, ELECTRIC AUTOMOBILE EQUIPPED WITH SAID COOLING DEVICE, AND ELECTRONIC DEVICE

摘要

A cooling device (5) circulates refrigerant (30) through a heat receiving section (8), a heat radiation channel (9), a heat radiating section (10), a return channel (11)and the heat receiving section (8) again, and cooling is achieved by the phase change between liquid and gas of the refrigerant (30). The heat receiving section (8) is configured from a plurality of heat receivers (7), each comprising an inflow port (12) and an outflow port, arranged in series. Check valves (14) are provided to the inflow port (12) sides of the heat receivers (7) which, of the plurality of heat receivers (7), are positioned nearest the return channel (11).
