Testing methods and apparatuses using simulated servers
The present application pertains to testing methods and apparatus useful in two-phase liquid immersion cooling systems. Such 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 two phase liquid immersion cooling so actual servers are not required to test various aspects of the two phase liquid immersion cooling units.
