Abstract

This application provides a dual-motor controller, a powertrain, and an electric vehicle. An accommodation part of the dual-motor controller is configured to accommodate two heat dissipation devices. A bottom of the accommodation part includes two first ports and two second ports, and each first port and each second port respectively communicate with an inlet and an outlet of one heat dissipation device. The two first ports are spaced apart in a first direction, and the two second ports are spaced apart in the first direction. Each first port and one second port are spaced apart in a second direction. An outer side of the accommodation part includes a coolant inlet and a coolant outlet, and the coolant inlet and the coolant outlet are opposite to each other in the first direction. The two first ports receive a coolant from the coolant inlet through one housing internal flow channel, and the two second ports output a coolant from the coolant outlet through the other housing internal flow channel. In this application, two parallel branches are formed by using housing internal flow channels and the heat dissipation devices, and the coolant inlet and the coolant outlet that are shared by the two housing internal flow channels are opposite to each other. This helps control path lengths of the two parallel branches, and avoids locally insufficient cooling.
