Optimization Design of Cooling Method for High Voltage Electric Motors
In order to solve the problem of difficult heat dissipation in high-voltage motors,this paper uses numerical simulation software to optimize and analyze the motor cooler.Firstly,the internal temperature and pressure fields of the cooler during operation are analyzed.It is found that the temperature drops to 53.7 ℃ after heat exchange between the inlet of the internal ventilation path and the heat exchanger.At the same time,due to the sudden change in fluid flow caused by the blocking plate,eddy currents are prone to occur at this position.Based on the simulation results,the cooler structure is optimized.After optimization,the temperature of the internal air path is reduced from 53.7℃ to 51.46 ℃ compared to the original plan.At the same time,according to the internal fluid velocity vector diagram,it can be seen that the internal vortex problem has been well solved.Overall,the optimization plan is feasible.
