Title:
COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/190868
Kind Code:
A1
Abstract:
This cooling device comprises a cooling tank (10), a circulation circuit (20), a heat exchanger (22), a circulation pump (21), and a heat conduction unit (13). The cooling tank (10) stores a refrigerant solution (11) that cools a heating element (2) by subcooled boiling. The circulation circuit circulates the refrigerant solution of the cooling tank. The heat exchanger is provided to the circulation circuit and cools the refrigerant solution. The circulation pump is provided to the circulation circuit and supplies the refrigerant solution to the heat exchanger. The heat conduction unit is provided in contact with the refrigerant solution and a gas (12) formed in the upper portion of the cooling tank by gas-phase refrigerant generated by evaporation of the refrigerant solution due to subcooled boiling, and promotes condensation of the refrigerant solution.
