摘要

Aiming at the reliability thermal design of avionics equipment,based on the reliability thermal simulation and analysis method of flotherm,the CFD digital prototype is established.The thermal simulation and thermal test of avionics equipment model are carried out at room temperature,and the results of temperature data of both are compared.The error is less than 5% to verify the correctness of the model.The thermal simulation analysis of the high temperature 70 °C environment conditions is carried out by using the simulation model,and the latent heat dissipation problems and weak links of the components in the thermal design of avionics equipment are obtained.The location and cause of potential failure are pointed out to guide the thermal design of avionics equipment and improve the reliability of avionics equipment.
