金属氢化物热泵及其在载人航天生保系统中的应用

介绍了金属氢化物热泵系统的工作原理和研究现状，分析了该系统在载入航天生命保障系统，特别是出舱航天服生命保障系统中应用的可能性，着重从系统体积，重量、物质消耗，再生时间和技术成熟度等方面比较了水升华器，相变储热，金属氢化物热泵等几种冷源各自的优缺点，说明了金属氢化物热泵系统在载入航天生命保障系统中应用的巨大潜力和需要研究的关键性技术问题。

METAL HYDRIDE HEAT PUMP AND ITS APPLICATION IN THE LIFE SUPPORT SYSTEM OF MANNED SPACE FLIGHT

In this paper, the working principle and research status of metal hydride heat pump are introduced, its application possibility to the life support system of manned space flight is analyzed. A comparison is made between different heat sinks, including water sublimator, phase change heat storage and metal hydride heat pump, from the aspects of size, weight, power, material waste and recovery time. The analysis shows that metal hydride heat pump system has wide application prospective in manned space flight. Some key techniques which must be considered firstly are stated.
