【Abstract】 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 as for thermal design are made to promote the performance of the heat sinks in a large space simulator. Finally, the typical procedure to perform quantitative thermal design of heat sink with HSDS is provided.更多还原
