11589483 · 2023-02-21 ·

The present invention discloses a three-chambered constant pressure apparatus for liquid immersion cooling of servers. The apparatus comprises a housing within which two partitions are disposed. The two partitions divide the housing into a first chamber, a second chamber and a third chamber. A coolant is maintained within the first chamber, and an isolating liquid is maintained within the second chamber and the third chamber. At least one heat-generating device is submerged within the coolant maintained within the first chamber. During the operation of a server, a coolant is heated to a boiling point temperature generating a coolant vapor that causes the pressure in chambers to rise. By adjusting the air pressure in chambers prior to use, the rising pressure in chambers caused by the coolant vapor can be efficiently relieved. Therefore, the immersion cooling apparatus is maintained at a constant pressure during operation, ensuring the reliability of the immersion cooling apparatus and the sustainability of cooling capacity.
