A built-in controller heat dissipation structure and a built-in controller

Abstract

The utility model belongs to control technical field discloses a built -in controller's heat radiation structure and built -in controller, heat radiation structure includes shell and heat dissipation fin, shell has the shielding cavity of open setting, shielding cavity is used to install controller body, shell is installed in the stator of motor to close shielding cavity, shell is electrically conductive spare, heat dissipation fin is established on shell and is located the side of the opening of shielding cavity in the face, heat dissipation fin includes a plurality of arc fin of the circumferential extension setting along motor axle. Since the shell is installed on the stator of the motor, a "Faraday cage" shielding space is formed with the stator, interference is effectively reduced, and normal operation of the controller body is ensured. Since the heat dissipation fin includes a plurality of arc fins extending circumferentially along the motor shaft, the special-shaped heat dissipation fin can improve the heat dissipation effect in dynamic and static states and improve the heat dissipation efficiency.
