Publication number: 20230413485Abstract: The disclosed technology is generally directed to vapor-air transition detection for two-phase liquid immersion cooling. In one example of the technology, a first device is cooled via two-phase liquid immersion cooling, such that the first device is submerged in a dielectric liquid in a system, and such that a boiling temperature of the dielectric liquid is a temperature that is suitable for keeping the first device cool. A portion of a first strip that is disposed in the system above the dielectric liquid is cooled. The first strip is composed of a thermo-conductive material. While the portion of the first strip is being cooled, via the first strip, a location of a vapor-air boundary in the system is determined based on a detected temperature along a length of the first strip.Type: ApplicationFiled: June 20, 2022Publication date: December 21, 2023Inventors: Eric Clarence PETERSON, Christian L.
