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.
