The invention provides a controller cooling component, a motor controller, a driving motor and a vehicle, the controller cooling component comprises a cooling shell, a cooling flow channel is constructed in the cooling shell, a plurality of heat dissipation fin plates with parallel extending directions are arranged in the cooling flow channel, the heat dissipation fin plates are projected on a bottom plate of the cooling shell, and, in the flowing direction of cooling liquid, the width of each heat dissipation fin plate is increased firstly and then decreased. According to the invention, the cooling fin plates are no longer of a rectangular structure in the prior art, but each cooling fin plate is of structure with the two ends being small in width and the middle position being large, on one hand, the structure can obviously reduce flow resistance of a cooling flow channel to cooling liquid and reduce the model selection cost of the corresponding cooling water pump, and on the other hand, compared with the rectangular cooling fin plate, the heat dissipation fin plates have the advantages that, on the premise that the same heat dissipating capacity is met, the overall size of the cooling flow channel can be designed to be smaller, and the material cost of the cooling shell and the heat dissipating fin plates can be reduced.

    本发明提供一种控制器冷却部件、电机控制器、驱动电机、车辆,其中的控制器冷却部件,包括冷却壳体,所述冷却壳体内构造有冷却流道,所述冷却流道内设有多条延伸方向平行的散热翅板,所述散热翅板在所述冷却壳体的底板上的投影上,沿冷却液的流动方向,所述散热翅板的宽度先增大后减小。根据本发明,散热翅板不再是现有技术中的长方矩形结构,而是两端宽度偏小而中间位置偏大的结构,这一结构一方面能够明显降低冷却流道对冷却液产生流阻,降低相应的冷却水泵的选型成本,另一方面与长方矩形的散热翅板相比,在满足相同的散热量的前提下能够使冷却流道的整体体积设计的更小,能够降低冷却壳体及散热翅板的材料成本。
