Cryogenic Heat Switch, Daniel Brodkey, Esteban Ruiz, Cristal Vasquez

Mechanical Engineering

A prototype cryogenic heat switch capable of transferring heat at cryogenic temperatures, while decoupling to prevent irreversible heat damage and minimizing parasitic heat loads, is to be developed for the Jet Propulsion Laboratory. Various material properties and cryogenic heat transfer processes will be investigated to determine the best solution for this project. A working proof of concept model will be constructed that may eventually be integrated onto a spacecraft’s passive cooler systems to protect them from the irradiation emitted by the sun, from the albedo of planets, and other malicious heat sources.
