Document Type and Number:
WIPO Patent Application WO/2019/146535
Kind Code:
A1
Abstract:
[Problem] To provide a cooling device capable of cooling a heat-generating body using simple configuration. [Solution] This cooling device comprises two evaporators, two condensers, a compressor and an expansion valve, and is configured so that any one among a first flow path setting, a second flow path setting, a third flow path setting, and a fourth flow path setting can be selected. In the first flow path setting, the refrigerant from the two evaporators flows to the two condensers without passing through the compressor. In the second flow path setting, the refrigerant from the first evaporator flows to one of the two condensers via the compressor, and the refrigerant from the second evaporator flows to the other one of the two condensers without passing through the compressor. In the third flow path setting, the refrigerant from the first evaporator flows to one of the two condensers without passing through the compressor, and the refrigerant from the second evaporator flows to the other one of the two condensers via the compressor. In the fourth flow path setting, the refrigerant from the two evaporators flows to the two condensers via the compressor.
