Pressure relief valve and adsorbent chamber for two-phase immersion cooling systems and methods for using same

A pressure relief valve for a two-phase immersion cooling system is configured to support fluid flow rates up to 500 cfm, 550 cfm, 600 cfm, or even 2000 cfm. This, in turn, allows the cooling system to support computing systems with a power density greater than 250 kW. This is accomplished by the valve having a relatively large passage (e.g., 2-6 inch diameter), a relatively large spring (e.g., 1.5-1.7 inch diameter), and a guide rod rigidly coupled to the poppet and slidably coupled to a guide plate. The valve may be used as an outlet valve and coupled to an adsorbent chamber to reduce the loss of coolant from the system as air is vented to an ambient environment. The valve may be used as an inlet valve and coupled to an adsorbent chamber to reduce the intake of water vapor as air from the ambient environment flows into the system.

CHECK VALVE AND DUAL CHECK VALVE WITH IMPROVED DAMPING

The invention is directed to a check valve (100) with an improved damping effect. The check valve comprises a housing (102) for fluid flow (F1) between an inlet port (1) and an outlet port (2), a valve member (110) being movable between a closed position (CP) and an open position (OP) having a sealing section (112) arranged and configured to contact a valve seat (108) in the closed position, an elastic element (114), arranged between the sealing section and a retaining member (106), wherein the check valve member comprises a guide section (116) extending downstream the sealing section. An inner chamber (118) is formed by the guide section and a chamber-forming element (120), such that a movement of the check valve member (110) varies a volume amount (V) of the inner chamber. The inner chamber comprises a venting passage (122) for fluidly connecting the outlet port to the inner chamber.

Jump valve

The invention relates to a mechanical valve assembly used to control a fluid (e.g., gas, liquid, etc.) to provide at least one of a check valve control feature and flow range control feature. When unwanted low flows are present, the valve remains closed and jumps open only at higher desired flow rates. The valve then closes when the forces at the input and output equalize, and the process repeats. Such allows fluid delivered to a flow meter in larger segregated bursts, rather than steady low flows that cause metering errors.
