Abstract

Taking a certain Thermoelectric cooling as the research object, we compared and analyzed the heat dissipation conditions of four radiators with different numbers of heat pipes under different currents, fin thicknesses, and different fin lengths of sub-fins, and obtained the radiator with the best heat dissipation and optimal operation working conditions. Research shows that when the current is 4A,the D-type’s chilly surface temperature rises to -19.6°C after decreasing to - 25.5°C, while the hot side temperature remains constantly rise. The greatest heat dissipation effect is achieved by Type D radiators, and the difference is most noticeable at 5A current. Compared to type A, the cold surface temperature is 3°C lower and the hot surface temperature is 6.9°C lower. The fin thickness of the D-type radiator was optimized using the controlled variable method. According to the study, the optimal conditions for heat dissipation are 1.25 mm fin thickness, 71.5°C hot surface, and -21.1 °C cold surface. Finally, a sub-fin is proposed and the length of the sub-fin is optimized by controlling variables. Studies reveal that the optimal conditions for heat dispersion are an 80 mm sub-fin length, 63.8°C for the hot surface, and -25 °C for the cold surface.
