Abstract

Aiming at reducing the difficulty of cooling the interior of high-density motors, this study proposed the placement of a water cold plate cooling structure between the axial laminations of the motor stator. The effect of the cooling water flow, thickness of the plate, and motor loss density on the cooling effect of the water cold plate were studied. To compare the cooling performance of water cold plate and outer spiral water jacket cooling structures, a high-speed permanent magnet motor with a high loss density was used to establish two motor models with the two cooling structures. Consequently, the cooling effects of the two models were analyzed using the finite element method under the same loss density, coolant flow, and main dimensions. The results were as follows. (1) The maximum and average temperatures of the water cold plate structure were reduced by 25.5% and 30.5%, respectively, compared to that of the outer spiral water jacket motor; .(2) Compared with the outer spiral water jacket structure, the water cold plate structure can reduce the overall mass and volume of the motor. Considering a 100 kW high-speed permanent magnet motor as an example, a water cold plate cooling system was designed, and the temperature distribution is analyzed, with the result indicating that the cooling structure satisfied the cooling requirements of the high loss density motor.

水冷板高损耗密度电机冷却系统的设计与分析
为了降低高密度电机内部冷却的难度,本研究提出在电机定子轴向片之间放置水冷板冷却结构。研究了冷却水流量、水冷板厚度、电机损耗密度对水冷板冷却效果的影响。为了比较水冷板和外螺旋水套两种冷却结构的冷却性能,以高损耗密度高速永磁电机为研究对象,建立了两种冷却结构下的电机模型。因此,在相同损失密度、冷却剂流量和主要尺寸下,采用有限元方法分析了两种模型的冷却效果。结果如下:(1)与外螺旋水套电机相比,水冷板结构的最高温度和平均温度分别降低25.5%和30.5%;(2)与外螺旋水套结构相比,水冷板结构可以减小电机的整体质量和体积。以100 kW高速永磁电机为例,设计了水冷板冷却系统,并对其温度分布进行了分析,结果表明该冷却结构满足高损耗密度电机的冷却要求。
