摘要

由于飞行器起飞时会产生热量,因此飞行器电机的热特性对于电动飞行器的设计至关重要。本研究对水冷式 AFPM 电机进行了数值模拟,以获得传热特性。计算域采用简化的冷却剂通道,并考虑了铜、铁的电磁损耗和涡流。假定稳态不可压缩流代表电机额定功率为 150 千瓦的巡航飞行状态。通过改变 4 分区情况下的通道配置,分析了系统压力损失和线圈温度。要解决热失衡问题,最好是在上游增加通道分区的数量,并在下游逐渐减少。这项研究使航空飞行器的电机设计人员能够提前对各种冷却剂通道配置进行数值评估。

A numerical study on heat release characteristics on configuration of coolant passages in air vehicle motor

Heat characteristics of air vehicle motors are essential for the design of electric aircraft because of heat generation when air vehicle takes off. In this study, the numerical simulation of a water-cooled AFPM motor was carried out to obtain heat transfer characteristics. A simplified computational domain was adopted with coolant passages, and electromagnetic losses of copper, iron, and eddy currents were considered. The steady-state and incompressible flows were assumed to represent the cruising flying condition of the 150-kW power rating in the motor. The system pressure loss and coil temperature were analyzed by changing passage configurations in 4-partition cases. To resolve thermal imbalance, it is best to have the number of channel partitions increase upstream and gradually decrease as you go downstream. This study allows motor designers for air vehicles to evaluate various coolant passage configurations numerically in advance.
