A hybrid cooling system is disclosed that combines a liquid coolant cycle and a refrigerant cycle to efficiently and effectively transfer heat away from a heat-generating component of a computing device. The liquid coolant cycle pumps a liquid coolant through a cold plate to extract heat from the heat-generating component. The heated liquid coolant passes through a coolant-to-refrigerant heat exchanger, where refrigerant from the refrigerant cycle absorbs the heat from the liquid coolant. The heated refrigerant passes through a compressor to a condenser, where the high-pressure, heated refrigerant is cooled by air passing over the condenser. The hybrid cooling system enables cooling of a heat-generating component better than by non-hybrid cooling systems.

A cooling device 10 comprising a first evaporation unit 11, a second evaporation unit 12, a first condensation unit 21, a second condensation unit 22, common piping CP, a compressor 30, an expansion valve 40, a first valve 71, and a second valve 72. The common piping CP combines liquid-phase refrigerant LP-COO flowing from the first condensation unit 21 and liquid-phase refrigerant LP-COO flowing from the second condensation unit 22. The first valve 71 adjusts the liquid-phase refrigerant amount LP-COO flowing into the first evaporation unit 11. The second valve 72 adjusts the liquid-phase refrigerant amount LP-COO flowing into the second evaporation unit 12. In addition, the pressure P0 inside the common pipe CP is greater than the respective pressures P1 and P2 inside the first evaporation unit 11 and the second evaporation unit 12. Thus, the length of the piping can be shortened.

The present invention relates to an air-vapor separation method for separating air from refrigerant vapor in an immersed liquid-cooling system. The immersed liquid-cooling system comprises an immersed server blade cabinet, a condensing device, an air-vapor separator and a refrigerant storage tank, wherein the refrigerant storage tank supplies a liquid refrigerant to the immersed server blade cabinet, and the liquid refrigerant undergoes a phase change to be vaporized into a refrigerant vapor for cooling of the heating element in the immersed server blade cabinet; the condensing device condenses the refrigerant vapor; the air-vapor separator separates a mixed gas in the immersed liquid-cooling system into the air and the refrigerant vapor. The cooling efficiency of the liquid-cooling system is improved by effectively separating the air from the refrigerant vapor in the liquid-cooling system.
