摘要
为提高电机控制器的冷却效率,以一款60 k W水冷电机控制器为研究对象,采用有限元方法建立了电机控制器的散热模型,为消除不同网格尺寸对仿真结果产生的误差对其进行网格无关性验证,并利用CFD软件进行仿真,分析了水道内不同高度、不同形状的扰流块对控制器散热性能的影响。仿真结果表明:在满足工艺要求和总压降的条件下,采用高度为0.7 mm的菱形扰流块时,控制器散热效果达到最佳,这为控制器水道的选型提供了参考依据,具有工程实际参考价值。
In order to improve the cooling efficiency of the motor controller,a 60 k W water-cooled motor controller is taken as the research object. The heat dissipation model of the motor controller is established by the finite element method to eliminate the error caused by different mesh sizes on simulation results,and verifies grid independence. The influence of the different height and shape of the block on the heat dissipation of the controller is analyzed by using the CFD software. The simulation results show that,under the condition of meeting the requirements of the process and thetotal pressure,the heat dissipation effect of the controller is best when using a rhombus block with a height of 0. 7 mm,which provides a reference for the selection of the controller waterway,and has great practical value in engineering research.
