Abstract: Temperature adjusting is an essential technology in space environmental simulation tests. The advantages, prospects and importance of its applications in space environmental testing are investigated. In the review of the technologies of temperature-adjustable heat sink, some key issues are analyzed, such as the technical characteristics of high- and- low temperature pumps and fans, the design indices of LN2 heat exchanger and ejector, the principle and application range of several cooling techniques, as well as the method of designing the electric heater, and the physical parameters of the heat transfer fluid. Finally, suggestions are made for developing temperature-adjustable heat sinks in China.
