The invention relates to a double-face heat dissipation motor controller, a power assembly and an electric vehicle, and belongs to the technical field of electric vehicles. The motor controller provided by the invention comprises a capacitor shell, a liquid cooling plate and two pipe joints. The capacitor shell comprises a containing cavity, a liquid cooling cavity and two first communication flow channels. The accommodating cavity is used for accommodating a capacitor core package. In the first direction, the liquid cooling plate, the liquid cooling cavity and the containing cavity are sequentially arranged in a stacked mode, and the power modules are arranged between the liquid cooling plate and the liquid cooling cavity. In the second direction, the two cooling liquid pipes are arranged on the two sides of the containing cavity, and the two first communicating flow channels are arranged on the two sides of the liquid cooling cavity. According to the motor controller provided by the invention, the liquid cooling cavity is integrated through the capacitor shell, and the liquid cooling plate and the liquid cooling cavity which are stacked are communicated through the two pipe joints, so that double-sided heat dissipation of a plurality of power modules in the motor controller is realized, and structure simplification and miniaturization of the motor controller are facilitated.
