摘　　要：使用车轮转角模块(WCM)的新能源城市车辆已成为研究热点。为满足WCM的多电机驱动方案,需要专门开发低成本、高可靠性、散热性能好且不需要附件系统的冷却方案。本文首先通过建立仿真模型,以研究WCM电机的产热特性和热负荷大小。然后提出了一种基于三维旋转脉动热管(RPHP)的电机冷却方案,该方案依靠重力以及旋转产生的离心力和空气气流来强化传热。实验结果表明,即使在1 r/min的转速下,RPHP仍能正常运行。在最大热负荷和最高转速时,RPHP的传热性能良好。在真实驾驶循环NEDC和WLTC循环下的电机转子热模拟器的最高温度远低于180℃的退磁温度。New energy city vehicles using wheel corner module(WCM)have become a research hotspot.To meet the cooling function of multi-motor,it is necessary to develop a solution with low cost,high reliability,good heat dissipation performance,and no attachment system.In this paper,the heat production characteristics and heat load of WCM motor are studied by establish-ing a simulation model.Then,a cooling scheme based on a three-dimensional rotating pulsating heat pipe(RPHP)is proposed,which relies on gravity and rotation to generate centrifugal force and airflow to enhance heat transfer.The test results show that the RPHP can still run nor-mally even at 1 r/min.The heat transfer performance of RPHP is good at maximum heat load and maximum speed.The maximum temperature of the rotor thermal simulator under the real driving cycle NEDC and WLTC cycles is much lower than the demagnetization temperature of 180℃.
