The invention discloses a controller of an electromobile. The controller comprises an upper cover and a shell. Multiple reinforcing ribs are arranged on the outer surface of the shell. A heat dissipation channel is formed between every two adjacent reinforcing ribs. The shell and the reinforcing ribs are all made of materials with high heat dissipation coefficients. For a power unit of the controller of the electromobile, the shell serves as a heat dissipation cover, the reinforcing ribs serve as heat dissipation fins, and heat dissipation efficiency is greatly improved by increasing the heat dissipation area of natural air cooling of the controller on the premise that the size of the controller is not increased. Meanwhile, the strength of the shell can be improved through the reinforcing ribs. 本发明公开了种电动汽车控制器，它包括上盖和壳体。在壳体的外表面设置有多个加强筋，相邻两加强筋之间形成散热通道；壳体和加强筋均由散热系数高的材料制成，对于电动汽车控制器的功率单元而言，壳体作为散热罩，加强筋作为散热翅，在不增大控制器体积的前提下，通过增加控制器自身自然风冷的散热面积，极大地提升了散热效率；同时，加强筋还能提高壳体的强度。
