Title:
COOLING DEVICE AND CAVITATION PREVENTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/042906
Kind Code:
A1
Abstract:
This cooling device uses a refrigeration cycle in which a refrigerant receives heat from an evaporator, the refrigerant is compressed, heat is dissipated from the refrigerant, the pressure of the refrigerant is lowered by an expander, and the refrigerant is fed to the evaporator. The cooling device comprises: a tank that receives the refrigerant whose pressure has been reduced by the expander; a pump that sucks in the refrigerant from the tank and feeds the refrigerant to a flow path heading toward the evaporator; and a bypass flow path that branches off of the flow path and feeds a portion of the refrigerant into the tank.
