建立载人航天器热控系统内各组成部分传热和质量的数学物理模型,对热控流体回路进行轻量化设计,并讨论相关参数对优化结果的影响。研究发现,在回路散热任务给定时,回路各组成部分的结构参数和辐射器内的散热管道数都存在最佳值,在该值下回路系统质量达到最轻。随着辐射器散热面积的增加,最优的辐射器内散热管道数减少;在给定辐射器散热面积时,当回路散热任务增加时,回路最优设计质量和辐射器内的最优管道数均增加。
The mathematic and physical model of heat transfer and mass transfer in the thermal control system of manned spacecraft was established. The heat control fluid circuit was designed with light weight, and the influence of relevant parameters on the optimization results was discussed. The study found that when the loop cooling task is given, the structural parameters of each component of the loop and the number of cooling ducts in the radiator have an optimal value, and the quality of the loop system reaches the lightest value. As the radiating area increases, the optimal number of radiating pipes in the radiators decreases. When the heat dissipation of the radiators increases, the optimal design quality of the circuit and the optimal number of pipes in the radiator Increase.
