摘　　要：分析了大型空间环模器热沉壁面温度分布的主要影响因素 ,利用热沉管网动态仿真软件 (HSDS)研究了不同热沉片结构对支管流量分配的影响 ,针对我国某大型空间环模器热沉在热设计方面存在的主要问题提出了简单可行的改进方案 .最后 。The main factors influencing heat sink wall temperature distribution of large space simulators are analyzed. Fin-tube flow rate allocation of heat sinks with different structures are studied with heat sink dynamic simulation software HSDS. Simple and feasible improvements for thermal design are made to promote the performance of the heat sinks in a large space simulator. The main idea is to improve the structure of the heat sink by changing the numbers of inlets and outlets, since the well-distributed wall temperature of a heat sink can not be obtained by simply flow adjustment. Finally, the typical procedure to perform quantitative thermal design of heat sink with HSDS is provided.
