Abstract:
To explore the influence of channel structure on the heat dissipation effect of electric vehicle drive motor of four different powers, the three-dimensional model of fluid flow and heat transfer in the shell was established. Fluent simulation was employed to calculate the flow field and temperature field of two different channel structure drive motors of different power. The results showed that only the six-channel structure could supply the demand of the heat dissipation when the motor power was more than 100 kW. When the motor power was 80 kW and 90 kW, the maximum temperature of the inner wall surface of the four-channel structure was 12.05% and 12.48% higher than that of the six-channel structure, respectively. At this time, the two kinds of channel structure could meet the heat dissipation requirement, but the pressure loss of the four-channel structure was 61.87% and 61.38% lower than that of the six-channel structure under the two kinds of power, respectively. Therefore, considering the difficulty of processing and the pressure bearing capacity of the shell, the four-channel circumferential "Z" shape structure should be preferred at lower power.
