According to one embodiment, a cooling system includes a primary condenser, a primary supply line and a primary return line that couples the primary condenser to a cold plate that is arranged to be used for electronics cooling to create a primary heat-transfer loop in which the condenser supplies liquid coolant to the cold plate and receives vapor produced by the cold plate, a secondary condenser, a secondary supply line that couples the secondary condenser to the primary supply line, a secondary return line that couples the secondary condenser to the primary return line, and a primary valve that is coupled to the secondary return line, where, in response to vapor pressure exceeding a pressure threshold, the valve at least partially opens to create a secondary heat-transfer loop in which the secondary condenser condense vapor back into liquid coolant that is supplied to the primary supply line.

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.

A two-phase immersion cooling system for cooling electronics. The electronics are immersed in immersion tank filled with phase change liquid. As liquid evaporates due to heat generated by the electronics, it enters a vapor passageway that leads the vapor to a condenser situated remotely from the immersion tank. Upon condensing at the condenser, the condensed liquid is directed to a resupply tank, wherein the condensed liquid cools. When the level of the two phase liquid in the immersion tank drops below a set threshold, a pump is activated to deliver the condensed liquid from the resupply tank to the immersion tank. The immersion tank, vapor passageway and condenser are position inside a containment passageway. The containment passageway captures any vapor not entering the vapor passageway and direct such vapor to the condenser. An air mover generates pressure differential within the containment passageway to direct the vapor towards the condenser.

A device for and method of hot swapping one or more electronic devices from an immersion cooling tank having a first opening, the device including a condensing unit removably locatable in first opening of the immersion cooling tank, the condensing device having a condensing coil forming a second opening through which the electronic device(s) is removable. A retractable cover sheet assembly, under computer control, is positioned to form a sized opening, which may include a containment structure, prior to opening the tank lid to minimize dielectric fluid loss.
