CROSS-REFERENCE TO RELATED APPLICATIONS

This application is related to PCT publication WO2020/102090 filed Nov. 11, 2019 titled “Liquid Immersion Cooling Platform” owned by TMGCore, LLC which application is incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to, for example, two-phase liquid immersion cooling systems with a liquid level measurement and monitoring device.

BACKGROUND AND SUMMARY

Halocarbons such as perfluorocarbon liquid dielectric fluids such as NOVEC™ are frequently employed in immersion cooling of computer components such as servers. The fluid may be lost for various reasons such as when servers are swapped or due to leaks in the system. The loss of even small amounts of fluid can be both expensive and deleterious to the system. Many common level sensors such as optical or ultrasonic types may not be particularly effective when used with fluorocarbon liquids. Accordingly, what is needed are new methods and systems for measuring the liquid level that are precise, efficient and/or effective.

Advantageously, the instant application pertains to new liquid level monitoring apparatus, methods, and systems. In one embodiment, the application pertains to a liquid level measurement device comprising a load cell and a buoyancy element. The buoyancy element is configured to be partially submerged in the liquid phase. The load cell and the buoyancy element are operably connected such that a change in liquid level may be determined using (1) the change in force measured by the load cell, (2) the density of the buoyancy element, (3) the cross-sectional area of the buoyancy element, (4) the density of the liquid, and (5) the movement of the buoyancy element due to the change in force on the load cell. That is, Archimedes' principle is employed.

In another embodiment the liquid level measurement device is employed in an immersion cooling system for computing components. In addition to the measurement device, the system comprises a vessel configured to contain a dielectric fluid in both liquid and vapor phases. A rack is configured to hold one or more computer components such that one or more computer components are at least partially submerged within the liquid phase of the volume of thermally conductive, boilable, and condensable dielectric fluid. A condenser is configured for actively condensing a dielectric fluid from vapor phase to liquid phase.

These and other objects, features and advantages of the exemplary embodiments of the present disclosure will become apparent upon reading the following detailed description of the exemplary embodiments of the present disclosure, when taken in conjunction with the appended claims.
