Two phase containment system having controlled air flow
11612081 · 2023-03-21 · ·

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.
