摘　　要：针对长期驻月设施过月夜问题,基于月壤原位资源月昼蓄热、月夜期间释放热量可维持设施生存温度的理念,调研了不同加工工艺成型储热块的热物性,研究了单位体积圆柱形储热块热分析方法及边界条件选取,并进行了多周期的瞬态热仿真,获得了其储热性能和温度变化范围。结果表明:蓄热过程中恒温层耗散储热块约10%的热量,验证了热分析模型中月壤尺寸的合理性。To live through the lunar night for the permanent lunar facilities,the in-situ resources of lunar soil were used to store heat in the daytime and release heat during the lunar night to maintain the survival temperature of the facilities.The thermal physical properties of the heat storage blocks formed by different processing technologies were investigated.The thermal analysis method and the selection of boundary conditions for unit volume cylindrical heat storage blocks were studied.The multi cycle transient thermal simulation was carried out,and the thermal storage performance and temperature range were obtained.The results showed that the isothermal layer dissipated about 10%of the heat in the heat storage process,which verified the rationality of the lunar soil size in the thermal analysis model.
