Abstract: A system for detecting contamination in a two-phase immersion cooling system based on temperature differences between component surface temperature and fluid temperature, a previous component surface temperature and a present component surface temperature and a component surface temperature and a component surface temperature threshold value. Large differences between the component surface temperature and the fluid temperature or between the component surface temperature and a previous component surface temperature or a component surface temperature exceeding a component surface temperature threshold value may indicate contaminants in the fluid that are inhibiting the ability for the component to effectively transfer heat to the fluid. A temperature monitoring system may monitor the temperatures and communicate with a service system to apply corrective measures before the residue can cause significant damage to an information handling system.

Abstract: 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.
