Controller with annular flow guiding cavities

Abstract

The invention discloses a controller with annular flow guiding cavities. The controller comprises a controller body, a controller shell and a fixed auxiliary frame; the fixed auxiliary frame is installed on the controller shell; the controller body is installed in an inner cavity of the controller shell; multiple heat dissipation grooves are arranged at the periphery of the controller shell; the heat dissipation grooves extend along the length direction of the controller shell; multiple annular flow guiding cavities are arranged in the shell wall of the controller shell; the annular flow guiding cavities surround the inner cavity of the controller shell; multiple annular flow guiding cavities are sequentially distributed along the length direction of the controller shell; and the heat dissipation grooves communicate with the annular flow guiding cavities. The controller with the annular flow guiding cavities provided by the invention has the advantages of being stable in structure andexcellent in air circulation effect and the like.

Description

Technical field [0001] The invention relates to the technical field of electric vehicle controllers, in particular to a controller containing an annular diversion cavity. Background technique [0002] Generally speaking, the electric vehicle is a battery as the energy source, and then through the cooperation of the controller and the motor and other components, the electrical energy is converted into mechanical energy movement, and the speed of the vehicle is changed by controlling the current. The electric vehicle saves energy and protects the environment. , The scale of consumption is expanding year by year, but the current controller still has many problems, such as the controller out of control when the rain is heavy, the controller itself is high in temperature after long-term work, and it is prone to short-circuit and damage, and the current partial control The thickness of the outer shell of the device is thin, and it is easy to be deformed and damaged during transportatio...

Problems solved by technology

[0002] Generally speaking, an electric vehicle is a battery as the energy source, and then through the cooperation of the controller and the motor, the electrical energy is converted into mechanical energy movement, and the speed of the vehicle is changed by controlling the magnitude of the current. The electric vehicle saves energy and protects the environment. , the scale of consumption is expanding year by year, but there are still many problems in the current controller, such as when the rain is heavy, the controller is out of control, and the temperature of the controller itself is high after long-term work, which is prone to short circuit and damage, etc., and the current partial control The shell of the device is thin, and it is prone to deformation and damage during transportation and installation
