摘要: 探索了多孔板的制造方法,设计了水升华器试验组件和试验装置,对不同的多孔板升华器在恒热流条件下进行了试验研究.试验重点研究了不同热流密度、多孔板物理参数、给水室压力及升华器放置情况对升华器性能的影响,并对水升华器的击穿特性进行了讨论.试验结果证明文中提出的升华器基本的设计概念是可行的,粉末烧结多孔板可以满足升华器的试验要求.最后,给出了关于水升华器进一步设计的一些有益的结论.

Abstract: Water sublimator is main heat sink of portable life support system of extravehicular activity (EVA) space suit. Manufacture techniques of porous plates are developed. Breadboard and tester of water sublimator are designed. An experimental study under constant heat flux is carried out on water sublimator with different porous plates. The attention is focused on the effects of heat flux, physical parameters of porous plate, pressure of feed water and placement on performance of sublimator. Breakthrough characteristics of sublimator are discussed. Test results have proved that the basic design concept of sublimator is feasible and that sintered powder porous plates can meet experimental needs of sublimator. Finally, some useful conclusions about further design of sublimator are presented.
