中文摘要：
为优化太空辐射器的设计，基于（火积）理论对太空辐射器的散热过程进行优化分析，分析结果表明辐射温度均匀性越好，太空辐射器辐射传热过程（火积）耗散越小，辐射器平均温度越低。以提高温度均匀性为目标设计了四种辐射器方案，并对不同方案进行仿真分析，仿真结果表明采用热管与流体管路组成传热网络后，辐射器温度均匀性最好，对外散热能力增强，流体回路热控系统整体温度下降，辐射器整体传热性能最优。
英文摘要：
In order to optimize the design of space radiator, heat transfer optimization is analyzed for the radiator based on the entransy theory. According to the analysis, the more evenly the radiator temperature is distributed, the less the entransy dissipation of the radiation is, and the lower the average temperature of the radiator is. In order to increase the temperature uniformity, four radiators are designed and compared numerically. The results show that the radiator netted with heat pipes and fluid loop has the most evenly distributed temperature and the highest capability of heat dissipation, as well as the lowest entransy dissipation among the 4 radiators.
