| Abstract: | Objective To investigate the development method of porous plate,the key part of water sublimator,and its main physical characteristics. Method Technical parameters of porous plates used in water sublimator were analyzed. On the basis of this, porous plates made of different materials were developed by making use of sintered powder technology. A tester for testing the physical characteristics of porous plate was designed. All around physical characteristic tests for porous plates were conducted. Result Main factors affecting performance of porous plates were tested. These provided basis for performance test of sublimator, established porous plate criterion and optimized porous plate. Conclusion Porous plates developed by making use of sintered powder technology could meet requirements of performance of water sublimator. |
