Classification: CPC H  B  F | IPC B  F  H

Claim 21:
22. A two-phase immersion cooling system, comprising:
a tank defining a tank volume configured to contain one or more printed circuit boards having semiconductor die that generate heat;
coolant liquid, disposed within the tank volume, configured to immerse the one or more printed circuit boards and remove the heat from the respective semiconductor die via vaporization thereby producing coolant vapor; and
an outlet valve assembly coupled to the tank, the outlet valve assembly comprising:
a pressure relief valve having an open position and a closed position, the valve being configured to remain in the closed position and only move from the closed position towards the open position when A) a first pressure applied to an inner side of the valve by a first mixture of air and the coolant vapor is greater than a second pressure applied to an outer side of the valve by a second mixture of air and water vapor in an ambient environment surrounding the system and B) a pressure difference between the first pressure and the second pressure is greater than a pressure threshold of the valve, wherein:

the pressure threshold of the valve ranges from about 0.5 pounds per square inch (psi) to about 2 psi; and
when the valve is at the open position or between the open position and the closed position, the valve is configured to allow the first mixture to flow through the valve at a rate ranging from about 0 cubic feet per minute (cfm) to about 2000 cfm.
