The development of micro and nano satellites needs a new type of high efficiency thermal control technology. The highly efficient thermal control system based on graphene is implemented on the main structure of micro and nano satellites, which has good effect on reducing the hot spot temperature and pulling the average intra-satellite temperature. In this paper, the composition and properties of graphene-based micro-nano satellite thermal control structure and the test system construction and experimental study on the heat transfer characteristics of the thermal control structure under vacuum and low temperature are introduced.
