The development of micro-nano satellites requires a new type of high-efficiency thermal control technology. The high-efficiency thermal control system based on graphene is implemented on the main structure of micro-nano satellites,which has good effect on reducing hot spot temperature and balancing average temperature inside satellites. In this paper,the composition and characteristics of graphene-based thermal control structures of micro-nano satellites are introduced,and the testing system of heat transfer characteristics of this thermal control structure under vacuum and high and low temperature is built and tested.
