摘要: 对舱外航天服热控系统所采用的多孔板水升华器的主要工作模式进行了讨论。研究了控制升华模式和周期模式工作的参数。在对多孔板多孔结构进行简化假设的基础上,建立了相关的数学模型,来预测水升华器的工作模式和换热器表面的温度。

Abstract: Some operation modes of the porous plate water sublimator used in an EVA space suit thermal control system are discussed. Parameters that affect sublimation mode and cyclic mode are studied. Based on some assumptions of porous plate structure, relevant mathematics models are established,which can be used to predict the operation mode of the sublimator and surface temperature of the heat exchanger.

Key words: water sublimator, porous plate, operation mode, EVA space suit
