Abstract
This paper presents a heat transfer system, in which a radiant cooler, cryogenic heat pipes and flexible thermal links were developed for heat transfer, by which a cryogenic system was cooled down to 200K from room temperature. A scrolling mechanism was designed for the radiant cooler to anti-contamination and block sunlight in the initial orbit phase. The cryogenic heat pipe is a type of grooved heat pipe with the working fluid of ethane and working temperature ranging from 160K to 210K. Some experimental and simulation results of the radiant cooler, cryogenic heat pipes will be discussed in this paper.
