Abstract: Thermal control is an interdisciplinary subject formed by the mutual promotion of engineering thermophysics and aerospace technology, directly affecting the overall design level of spacecraft. With the rapid development of space industry, thermal control design has appealed to higher requirement that becomes one of the key bottlenecks restricting the level spacecraft design. In this paper, the latest research and progress in the construction of the new thermal control system for spacecraft in China are reviewed. Existing research results show that the new thermal control systems are constructed to meet the needs of different tasks such as manned spaceflight and lunar exploration, developing a number of new thermal products, such as pumped fluid loops, closed two-phase thermosyphons, and loop heat pipe and sublimator. In the end, based on the requirement of the domestic space engineering, this paper outlines the main research directions in thermal control technologies.
Key words: spacecraft, thermal control, thermal bus, pumped fluid loops, loop heat pipe, sublimator
