Embodiment 1

[0019] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see figure 1 : A motor controller, which also includes at least one heat conduction device sealed and filled with a heat conductor, the shell of the heat conduction device is made of heat conduction material (such as metal material, aluminum, etc.), and the circuit board 4 of the motor controller is insulated and supported on In the casing, the circuit board 4 or components that need heat dissipation are closely attached to the heat conduction device, and the heat dissipation channel of the motor controller is formed between the components 4 that need heat dissipation of the motor controller, the shell of the heat conduction device, and the heat conductor. The shell can be made of aluminum or carbon fiber. Carbon fiber conducts heat better, but the cost is high, and it is not limited to the aluminum shell.

Abstract

The invention belongs to the technical field of motor controllers. A motor controller comprises a heat conduction device which is at least filled with heat conductors including phase change material in a sealed manner. A housing of the heat conduction device is made of heat conduction material. A circuit board of the motor controller is supported inside the housing in an insulated manner. The circuit board or components needing heat dissipation are tightly adhered to the heat conduction device. Heat dissipation channels of the motor controller are formed among the components needing heat dissipation, the housing of the heat conduction device and the heat conductors of the motor controller. Phase change material is applied to the controller, a lot of heat produced by a power tube or a circuit board is absorbed by the phase change material, heat absorbed during a phase change process is mostly used for phase change of substances, a small amount of the heat is used for temperature increasing, so that the temperature of the phase change material increases a little during the phase change process. Therefore, the overall temperature of a product increases slowly, and thus, more sufficient time is provided for heat dissipation of the outer surface of the housing.

Description

technical field [0001] The invention belongs to the technical field of motor controllers, in particular to a motor controller. Background technique [0002] The commonly used power devices of the motor controller are field effect tubes or IGBTs, etc., and the heat generated by the power devices is conducted by pressing against metal heat conducting (dissipating) bodies. Power devices and metal radiators must be insulated from each other with insulation such as insulating sheets. This type of heat conduction method involves the pressing installation process of power devices and metal heat conduction devices and also deals with insulation problems. And due to the constraints of the current technical conditions, to achieve the purpose of the motor controller, the number of power devices required varies from 6 to 48, and the number of power devices from 6 to 48 must be pressed onto the metal heat conducting device. , and requires insulation from the metal heat conduction devic...
