Abstract: The present disclosure refers to methods of employing a computer comprising a pulse width modulated controlled cooling fan in an immersion cooling process. The present disclosure also refers to devices therefore. Such methods and devices employ a direct conversion or a probabilistic approach to emulate the operation of a pulse width modulated controlled cooling fan. The aforementioned methods and devices may be particularly useful for fans having a fan speed of 25,000 rpm or higher.

Abstract: The present disclosure refers to methods and electronics used to test immersion cooling controllers. A representative method comprises operably connecting a simulator device to an immersion cooling controller. The simulator device is used to communicate one or more changes to the immersion cooling controller wherein the one or more changes relate to one or more sensed parameters of an immersion cooling system. The reaction of the controller to the one or more changes is compared to an expected reaction of the controller to determine whether the controller is functioning properly. The controller may be configured to control any parameter of an immersion cooling system including, but not limited to, temperature, water flow, pressure, fluid level, fluid purity, and any combination thereof.

Abstract: The present disclosure refers to an immersion cooling system and process. Representative embodiments include an interface for interconnecting the inside of the vessel to the outside using an exemplary pass through plates. Additional embodiments include carbon tapes at the opening areas of the vessel. In one example embodiment, a ledge for returning any fluid that is condensed on the top door of the vessel may be provided. Representative features also may include roller covering or overlays, pipes to deliver a spray to clean components, and/or cooling a pump to prevent premature failure. Other embodiments include mechanisms for pump life improvement, gap fillers to reduce fluid needed, and improved vapor management techniques.

Abstract: The instant application pertains to new liquid level monitoring apparatus and a cooling system for computer components that employs the liquid level monitoring apparatus. In one embodiment, the liquid level measurement device comprises a load cell and a buoyancy element. The buoyancy element is configured to be partially submerged in a dielectric liquid. The load cell and the buoyancy element are operably connected such that a change in liquid volume may be determined using Archimedes' principle.

Abstract: The present application pertains to testing methods and apparatus useful in single phase or two-phase liquid immersion cooling systems. Single phase systems use a fluid similar to mineral oil in which to immerse the servers. As the fluid is heated by the operating servers the fluid is circulated to one or more heat exchangers for cooling so the fluid never boils. In contrast, two-phase systems cool heat generating computer components which cause a dielectric fluid in its liquid phase to vaporize. The dielectric vapor is then condensed back into a liquid phase and used to cool the computer components. Using the testing methods and apparatuses herein one may design and test more efficient components and systems. More specifically, the one or more heating elements are both passive and intelligent. They may be used to mimic the power load of a server which is used in the load testing of immersion cooling so actual servers are not required to test various aspects of the liquid immersion cooling units.

Abstract: A two-phase liquid immersion cooling method is described in which heat generating computer components cause a dielectric fluid in its liquid phase to vaporize. The dielectric vapor is then condensed back into a liquid phase and used to cool the computer components. Using a pressure controlled vessel and pressure controller, a cooling system may be operated at less than ambient pressure. By controlling the pressure at which the system operates, the user may influence the temperature at which the dielectric fluid vaporizes and thereby achieve increased performance from a given computer component.
