Abstract

See full text

A cooling device includes a first evaporation unit, a second evaporation unit, a first condensation unit, a second condensation unit, common piping, a compressor, an expansion valve, a first valve, and a second valve. The common piping combines liquid-phase refrigerant flowing from the first condensation unit and liquid-phase refrigerant flowing from the second condensation unit. The first valve adjusts the liquid-phase refrigerant amount flowing into the first evaporation unit. The second valve adjusts the liquid-phase refrigerant amount flowing into the second evaporation unit. In addition, the pressure inside the common pipe is greater than the respective pressures inside the first evaporation unit and the second evaporation unit.
