Classification: CPC H  B  F | IPC B  F  H

Claim 9:
10. 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 inlet valve assembly coupled to the tank, the inlet 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 outer side of the valve by a first mixture of air and water vapor in an ambient environment surrounding the system is greater than a second pressure applied to an inner side of the valve by a second mixture of air and the coolant vapor and B) a pressure difference between the first pressure and the second pressure is greater than a pressure threshold of the valve; and
an adsorbent chamber, disposed between the pressure relief valve and the tank, containing desiccant to adsorb the water vapor in the first mixture as the first mixture flows through the adsorbent chamber thereby reducing a concentration of the water vapor in the first mixture flowing through the valve.
