文章提出了载人航天器的可重构式控温回路系统，它由独立的中低温内外回路系统组成，可改善低温内回路由于控温点温度较低而对辐射器散热能力带来的影响，还可在某个外回路辐射器故障时进行系统重构，维持回路功能。建立了控温回路系统非稳态仿真分析模型，对正常工作模式下和某外回路故障工作模式下各舱回路控温点温度、设备温度、流量分配和载人航天器热负荷水平进行了分析。结果表明，双外回路系统比单外回路系统散热能力高27%。当双外回路中某回路故障时，通过系统重构，外回路系统可维持1850 W散热能力，能保障载人航天器平台安全，表明可重构式控温回路系统能提高系统可靠性。

A thermal control loop system with a reconfigurable structure for the space station is proposed, which contains independent low and moderate temperature inner loops and external loops. In this design, the negative effect of the radiator heat dissipation due to the low temperature of the low temperature inner loop could be alleviated. Furthermore, the loop structure could be reconfigured when the radiator of one external loop fails, to maintain part of the function. An unsteady simulation model of the thermal control loop is developed. Based on this model, the characteristics of the reconfigurable thermal control loop system with the normal pattern and the one loop failure working pattern are analyzed, including the temperatures at the controlling points and in the equipment, the flux distribution, the heat load level of the space station. According to the results, the heat dissipation level of the double external loop system is shown to be higher than that of a single-external loop system by 27%. When the radiator of one external loop fails, the heat dissipation of 1850 W can be maintained, which can ensure the safety of the space station, indicating that the reconfigurable design can improve the system reliability.
