Abstract

本发明涉及一种油冷电机定子冷却结构，包括外喷油冲片层、轴向导油冲片层以及环向进油冲片层；所述轴向导油冲片层布置于外喷油冲片层和环向进油冲片层之间，所述外喷油冲片层上形成有用于冷却油液喷射的阶梯油道，所述轴向导油冲片层上形成有连通阶梯油道的轴向导流油道，冷却油液从所述环向进油冲片层处进入轴向导流油道并通过阶梯油道与外喷油冲片层安装径向方向以设定的倾斜角度喷射；本发明的油冷电机定子冷却结构，通过环向进油冲片层将油液导入到轴向导流油道，最终通过端部的阶梯油道将冷却油液喷出，对内部绕组以及其余部件进行冷却，冷却油液覆盖更加均匀，内部部件冷却效果得到提升，提升了散热均匀性，整体结构简单，降低了生产成本。
