Document Type and Number:
WIPO Patent Application WO/2022/190766
Kind Code:
A1
Abstract:
The present invention comprises: a cooling tank (10) that stores a refrigerant liquid (11) for immersing and cooling a heat generating body (2); a liquid storage tank (20) that stores the refrigerant liquid outside of the cooling tank and has a vent opening (21) that is open to the air; and a connecting section (30) that connects the liquid storage tank and the cooling tank and is configured such that the refrigerant liquid can pass therethrough. A cooling tank-side opening (31) formed on the cooling tank side of the connecting section is positioned below or at the same height as the liquid surface of the refrigerant liquid in the cooling tank in the direction of gravity. A gas generated in the cooling tank accumulates in the upper section of the cooling tank and forms a gas section (12). The refrigerant liquid flows between the cooling tank and the liquid storage tank via the connecting section in response to changes in the volume of the gas section.
