一种新型电机用冷却装置

A new cooling device for motor

目前对于高功率密度电机主要采用机壳水冷装置进行冷却,对电机内部降温效果较差.提出一种新型的电机冷却方法,即在机壳内部设置热空气通道与冷却水通道,两者直接发生热交换,将电机内部热量带出,避免电机内部产生局部过热.

Nowadays, it is usually internal temperature cooling schemes of motors with high power density that devices with water- cooling have placed inside the frame of motors while in the present work devices with both water- cooling channels and airconditioning those have been employed to make both channels heatex- changing directly, which will bring out the greater internal heat of motors as opposed to usual schemes and thus avoid local overheating.
