Abstract
Three kinds of novel permanent magnet synchronous motors (PMSM) integrated with heat pipe whose evaporator is treated in different ways for electric vehicle are designed in order to decrease the end winding temperature. The influence of the geometric parameter of the cooling water channel on the thermal–hydraulic performance is analyzed. The temperature difference between the cooling water and the housing decreases, while the pressure loss increases with the spiral number increasing. Channel width and channel height have little influence on the temperature difference but have an apparent effect on the pressure loss. FLUENT, CFD software, is used to simulate the heat dissipation performance of the PMSMs. The highest temperatures of the end winding are 149.9 °C, 140.1 °C, 133.5 °C, and 139.6 °C for the traditional PMSM and the three new PMSMs, respectively. The lowest temperatures of the lamination of the four PMSMs are close. So are the highest temperatures of the lamination. The lowest temperature distribution profiles of the housing of the three new PMSMs do not change apparently compared with that of the traditional PMSM. It shows that after the optimization of the cooling water channel, the cooling water system of the new PMSMs works efficiently although more heat is transferred to the housing. Among the traditional PMSM and the three new PMSMs, new PMSM b shows the best heat transfer capacity.
