Abstract
This cooling device is equipped with a tank, a pump, an evaporator, and a condenser. The gas phase portion of the tank is filled with a filler gas and is equipped with a volume-changing unit. The volume-changing unit is configured to adjust an evaporation temperature of the refrigerant by changing a pressure of the refrigerant, which is achieved by changing a volume of the gas phase portion to change a pressure of the filler gas.
Claims8
A cooling device comprising:
- a tank configured to store a liquid refrigerant;
- a pump configured to discharge the liquid refrigerant stored in the tank;
- an evaporator configured to cool a cooling target by evaporating the liquid refrigerant discharged from the pump;
- and
- a condenser configured to condense a gaseous refrigerant generated by the refrigerant evaporated by the evaporator,
- wherein a gas phase portion of the tank is filled with a filler gas and is equipped with a volume-changing unit, the volume-changing unit being configured to adjust an evaporation temperature of the refrigerant by changing a pressure of the refrigerant, which is achieved by changing a volume of the gas phase portion to change a pressure of the filler gas.
