Abstract
A pressure control system within a multi-phase heat transfer immersion cooling tank includes: a differential pressure transducer that measures a differential pressure between a first vapor pressure internal to the immersion cooling tank and a second pressure outside of the immersion cooling tank; and a condenser inflow valve assembly that controls a flow rate of condensation liquid within the condenser located within the immersion tank. The pressure control system also includes a controller coupled to both the differential pressure transducer and the condenser inflow valve assembly having control logic that, in response to the measured differential pressure exceeding a pre-set threshold difference, triggers the condenser inflow valve assembly to increase a flow rate of the condensation fluid in order to reduce an amount of vapor within the immersion tank and bring the measured differential pressure back to below the threshold difference.
