In this paper, a structural prototype of an isotope thermoelectric power supply is designed based on thermal simulation experiments. Through software thermal analysis technology optimization, the heat transfer efficiency of the prototype is increased to 78%. The simulation results show that the temperature of the cold end of the thermoelectric module is about 396 K, and the temperature of the hot end is about 933 K, the temperature difference is about 440 K. The simulation results have reference significance for the application of the structural prototype to the actual radioisotope thermoelectric power source.
