OPENABLE AND CLOSEABLE CONDENSING APPARATUS
20220003433 · 2022-01-06 ·

The present invention discloses an openable and closeable condensing apparatus, which is particularly applied in a two-phase liquid immersion cooling system. When servers start to operate, a large amount of heat will be dissipated from servers. The coolant is vaporized into a rising coolant vapor by absorbing heat dissipated from servers. Upon contact with a condenser, the coolant vapor is condensed back into a cooling liquid that is returned to the coolant-containing tank. By the heat exchange cycle in which heat dissipated from serves is absorbed by the coolant, servers can be maintained at a normal working temperature. However, in the process of condensation, the rising coolant vapor tends to scatter in all directions resulting in a failure to condense all of the coolant vapor. Therefore, the uncondensed coolant vapor will cause the pressure in the system to gradually rise, which eventually leads to an ineffective cooling of servers. In view of this problem, the disclosed invention provides an enclosed-type condensing apparatus for completely condensing all of the coolant vapor.
