Thermally Cooled Compact Motor Controller

Abstract

The invention discloses a compact motor controller with good heat dissipation, which relates to the technical field of motor controllers. The motor controller comprises an upper shell, a lower shell,a control motherboard and a heat dissipation assembly. The upper shell and the lower shell are provided with vacuum chambers in the inner walls thereof. A miniature exhaust fan is fixed on one inner wall of the upper shell. The heat dissipation assembly comprises a heat dissipation shell and a cover, and one surface of the cover is fixedly connected with one surface of the heat dissipation shell.Water can be refrigerated through a semiconductor refrigerating sheet. Water circulation can be carried out through a micro water pump, a diversion chamber and a serpentine channel. Water cooling treatment can be carried out through a silica gel layer, the cover, a first heat conducting plate and a second heat conducting plate. Water circulation can be formed through the micro water pump, a waterintake pipe, a radiating pipe and a water outlet pipe. Air circulation can be formed and air cooling treatment can be carried out through the miniature exhaust fan, the radiating pipe, an air outlet chamber and an air return chamber. The problem that the existing motor controller has a poor heat dissipation effect is solved.

Description

technical field [0001] The invention belongs to the technical field of motor controllers, in particular to a compact motor controller with good heat dissipation. Background technique [0002] The motor controller is an integrated circuit that controls the motor to work according to the set direction, speed, angle and response time through active work. The motor controller adopts high-power intelligent modules, excellent cooling and heat dissipation systems, reliable power control systems, closed-loop The optimized composition of the sampling feedback control system has the characteristics of fast response, stable control operation and maintenance-free. [0003] In order to ensure waterproof performance, traditional motor controllers are sealed with a complete shell, which will cause poor heat dissipation and cannot use external air cooling for heat dissipation, and the use of liquid cooling components will cause too much space It is not convenient for the installation of co...
