The invention relates to a motor controller structure for a new energy automobile, and the structure comprises a box body and a box cover, and a filtering assembly, a thin-film capacitor, a PCB, a switching copper bar and a power heat dissipation assembly which are disposed in an inner cavity formed by the box body and the box cover, and the thin-film capacitor, the power heat dissipation assembly and the switching copper bar are connected in sequence. The power heat dissipation assembly comprises a ceramic substrate, a heat dissipation device, a pressing plate and a plurality of single tube modules, the ceramic substrate is arranged on the first side of the heat dissipation device, all the single tube modules are arranged side by side, arranged on the ceramic substrate and then pressed by the pressing plate, a heat exchange cavity is formed in the second side of the power heat dissipation assembly, and heat dissipation fins are arranged in the heat exchange cavity. Compared with the prior art, the overall integration degree is improved, a good heat dissipation effect is achieved, the design of the radiator is not limited to the influence of the internal structure of the box body any more, and the controller box body heat dissipation device can be compatible with different controller box bodies.

    本发明涉及一种新能源汽车用电机控制器结构,包括箱体和箱盖,以及设于箱体和箱盖所形成内腔中的滤波组件、薄膜电容、PCB板、转接铜排和功率散热组件,薄膜电容、功率散热组件、转接铜排依次连接,功率散热组件包括陶瓷基板、散热器、压板和多个单管模块,陶瓷基板设于散热器的第一侧上,所有单管模块并排设置并设于陶瓷基板上后由压板压紧,功率散热组件的第二侧内设有换热腔,换热腔内设有散热翅片。与现有技术相比,本发明提高了整体的集成度,不仅起到较好的散热效果,且散热器的设计也不再局限于箱体内部结构影响,能够兼容不同的控制器箱体。
