Design of cooling water channels for electric vehicle motors
The heat dissipation performance of the motor has an important impact on the working efficiency of the motor,and its temperature rise directly affects the stability and safety of the electric vehicle.Optimizing the design of cooling channels helps to improve the heat dissipation efficiency of motors,extend their service life,reduce energy consumption,and meet energy-saving and emission reduction requirements.Firstly,Maxwell was used to analyze the loss of the motor under normal working conditions,and then the equivalent three-dimensional model of the motor was established.Four kinds of cooling water channel models were established by means of shell water channel cooling.Fluent was used to analyze the heat dissipation performance of different cooling waterways,compare the comprehensive cooling effect of the waterways,and further study the influence of different water section sizes of four kinds of waterways on the heat dissipation performance of the motor.Finally,the comprehensive evaluation method was used to select the most suitable type and cross section size of the current motor.
