| Abstract: | In this paper, based on the special conditions of a space radiator, the heat transfer model is established. It is proved that the model and the calculation method are feasible by comparing with the actual designing process. With the fin length and fin thickness and other parameters selected as the variables, the heat dissipation of the fin in the heat pipe radiator and the quality characteristics of the system are analyzed and optimized, and finally the optimal design is found which has potentials in thermal design and analysis. |
