It USES the energy transformation of the loss of winding to the power to form a closed self circulation cooling system without pump.

是靠绕组损耗转化形成的动力进行密闭无泵自循环冷却。

One time adding liquid medium to the closed refrigeration circulation system can work for long time, cooling water can be save greatly.

在封闭冷却循环系统内一次加入液体介质能长期使用，可节约大量冷却水。
