摘要
为了研究不同水冷结构对水冷永磁电机散热性能的影响,以一台水冷永磁电机为研究对象,优化十字形肋片结构对轴向"Z"字形水路,通过分析加入水道中的十字形肋片的结构参数,确定横肋的高度和数量两个影响参数,采用Workbench对电机进行三维建模,获得不同横肋高度和数量下的电机各部温度分布.结果表明,对比分析电机各部分温升,得到最优冷却结构的横肋数量为3 时冷却效果最佳,定子、绕组、转子和永磁体的最高温度分别下降 15.32、15.41、11.24 和11.24℃.
Abstract
This paper intends to study the influence of different water-cooled structures on the heat dissipation performance of water-cooled permanent magnet motor.By employing a water-cooled permanent magnet motor as an example,the study works by optimizing the cross-shaped rib structure to the axial"Z"shaped waterway;determining the two impact parameters of the transverse ribs,such as the height and the number,by analyzing the structural parameters of the cross-type rib added to the waterway in de-tails;achieving the temperature distribution diagram of each part of the motor under different transverse rib height and number by using Workbench software.The results show that compared and analyzed the in-creasing temperature of different parts of the motor,the optimal cooling structure is achieved with 3 trans-verse ribs,and the decrease of top temperature of the stator,winding,rotor and permanent magnet by 15.32,15.41,11.24 and 11.24℃,respectively.
