    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.
