Current status and suggestions of satellite borne single-phase fluid loops

Enhancement of the load function and diversification put forward higher requirements for thermal control mode and the thermal rejection ability of the satellite. Limited to size, heat transfer efficiency, and mission characteristics of the satellite, thermal rejection ability has increasingly become one of the most important factors which restrict the mission of the satellite, and technical advantages and potential application of the single-phase fluid loops have become increasingly prominent. The single-phase fluid loop has been applied to China’s satellite field several times and has played an important role in long-distance heat transfer, expanding thermal rejection ability and improving system control ability. This paper describes the current application status of the single-phase fluid loops in China’s satellite field in recent years and provides some suggestions for developing and applying the single-phase fluid loops in the future. The single-phase fluid loop has become one of the important options for satellites with high power and distributed heat sources. Weight, layout, and micro-vibration are the major limited elements for space application, which should be further studied. Research on the high integration of products, new products, and vibration isolation technology is helpful and necessary.
