Abstract
The utility model relates to an electric vehicle controller with a high-efficiency heat radiation channel. A radiating seat of the electric vehicle controller has the heat radiation channel arranged on a side wall where a power switch tube is installed. The heat radiation channel and a switch tube placing chamber are arranged side by side. Radiating fins are arranged on the side wall provided with the power switch tube and located inside the heat radiation channel. The end face of the heat radiation channel is provided with a convection cooling device. Even if an electric vehicle runs with a heavy load and the temperature of the power switch tube rises rapidly, the heat radiation seat provided with the heat radiation channel can perform forcible heat radiation through the convection cooling device and make heat conducted by the power switch tube to the radiating fins guided away in time. Components inside the controller are prevented from being in a high-temperature condition for long. The service lifetimes of the components are prolonged. The electric vehicle is further prevented from being dysfunctional due to damage caused by overheat.
