Techniques for Controlling Vapor Pressure in an Immersion Cooling Tank
ActiveUS20150060009A1Eliminate increase in pressureMaximize the effectAir-treating devicesTemperatue controlDifferential pressureTransducer
A method that controls pressure within an immersion cooling tank having condensation fluid flowing through a condenser, includes: a controller receiving a signal that indicates a current level of vapor pressure within the tank; determining from the signal when the current level of vapor pressure exceeds or is below a first preset threshold pressure level; and in response to the current level of vapor pressure exceeding or being below the first preset threshold pressure level, signaling a flow control mechanism that modulates a flow rate of the condensation fluid through the condenser to increase or decrease the rate of flow from a current rate of flow. The controller receives the signal by a pressure sensor within the immersion cooling tank detecting the current vapor pressure, generating the signal and forwarding the signal to the controller. The pressure sensor can be a differential pressure transducer that measures a differential pressure internal to and outside of the immersion tank.

Fluid displacement system
In a fluid displacement system having a pressure vessel, an expansion vessel, first and second tubes in fluid communication with the two vessels, and an energy source, fluid contained within the system is transferred from one vessel to the other by activating the energy source, which in turn generates pressure in the pressure vessel. The generated pressure in the pressure vessel, in turn, displaces the fluid in the expansion vessel, and the system advantageously has no moving parts.
