Optimization study of air-cooled heat dissipation structure based on waterborne electric airplane

Abstract Taking the water electric aircraft as the research object, to solve the problem of high temperature of the motor, controller and radiator in the powerhouse when the aircraft is travelling under the high temperature condition in summer. Firstly, the three-dimensional model of the power module of the electric aircraft is established and simulation experiments are carried out, and then according to the simulation results, the power module is optimized and improved, and after simulation experiments, it is known that the highest temperature of the surface of the electric motor is 432.83K, the highest temperature of the surface of the controller is 370.82K, and the highest temperature of the surface of the radiator is 368.67K, and the final experimental results show that the optimization meets the cooling requirements of the aircraft flight. The final experimental results show that the optimisation meets the heat dissipation requirements of the aircraft flight.
