摘要: 针对人体穿着航天服处于过热状态下的散热问题,在分别建立人体热调节系统、金属氢化物冷源和液冷服数学模型的基础上,将3个模型进行结合,对舱外航天服热控系统在5.5h的时间轴上进行综合的仿真计算,求出人体各节段的温度分布情况,液冷服的入口及出口水温,金属氢化物冷源的出口水温等参数,分析航天员的热舒适性,对航天服热控系统的设计有一定的指导作用,并为今后进一步的研究打下了基础.Abstract: In this paper, heat dissipation of the human on Liquid Cooling and Ventilation Garment （LCVG） are discussed by linking the mathematics models of human ther-mal control system, metal-hydride cold source and Liquid Cooling Garment （LCG）. By simulating the EVA space suit thermal control system working condition for 5.5h, the temperatures of every part in the body, the inlet and outlet of LCG and the outlet of the metal-hydride cold source were obtained. The result might be utilized in the design of EVA space suit thermal control system and further inves-tigation.
