1. 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
a valve assembly coupled to the tank, the valve assembly comprising:
a pressure relief valve, comprising:
a valve body defining a passage;
a guide plate, directly coupled to the valve body, having a guide plate opening;
a poppet assembly slidably coupled to the valve body and the guide plate and movable between and including a closed position and an open position, the poppet assembly being configured to prevent a fluid from flowing through the passage at the closed position, the poppet assembly being configured to allow the fluid to flow through the passage at the open position or between the open position and the closed position, the poppet assembly comprising:
a stem slidably coupled to the valve body;
a poppet, directly coupled to the stem, having a first side and a second side opposite to the first side, the poppet sealing the passage to prevent the fluid from flowing through the passage at the closed position, the poppet being positioned to allow the fluid to flow through the passage at the open position or between the open position and the closed position; and
a guide rod directly coupled to the stem, inserted through the guide plate opening to laterally constrain the poppet with respect to the guide plate, and slidably movable with respect to the guide plate; and
a spring, disposed between the valve body and the poppet assembly, to apply a spring force to the poppet assembly such that the poppet assembly remains at the closed position and only moves from the closed position towards the open position when the fluid applies a first pressure to the first side of the poppet greater than a second pressure applied to the second side of the poppet and a pressure difference between the first pressure and the second pressure is greater than or equal to a pressure threshold corresponding to the spring force.
