Novel motor controller, a motor controller manufacturing method and electric automobile

Abstract

The invention relates to the technical field of motor controller, and particularly relates to a novel motor controller and an electric automobile. The novel motor controller comprises a shell, whereinthe bottom of the shell is equipped with capacitor bodies, cooling water pipe columns, IGBT connecting columns and a capacitor DC output terminal, and the shell is provided with a DC quick-connectionplug; the inner wall of the shell is integrally fixed with each capacitor body, each cooling water pipe column and each IGBT connecting column through heat conductive insulating packaging and fillingrubber block, and the capacitor DC output terminal and one end of the DC quick-connection plug connected with the capacitor DC output terminal are arranged in the heat conductive insulating packagingand filling rubber block; the upper end port of each cooling water pipe column extends out of the heat conductive insulating packaging and filling rubber block, the lower end port of each cooling water pipe column is hermetically connected with the shell, the upper end of the capacitor DC output terminal extends out of the heat conductive insulating packaging and filling rubber block, and the upper end of each IGBT connecting column extends out of the heat conductive insulating packaging and filling rubber block. The technical problems of poor cooling effect, overheat use and easy damage of the capacitor bodies in the controller in the prior art are solved through the design of the motor controller.

Description

technical field [0001] The invention relates to the technical field of motor controllers, in particular to a novel motor controller, a manufacturing method of the motor controller and an electric vehicle. Background technique [0002] Motor controllers inevitably generate heat during their work. Therefore, it is necessary to conduct the heat to the outside in a timely and rapid manner through the heat dissipation structure; otherwise, the functions of the related electronic components of the controller will be affected, and even the related electronic components of the controller will be burned, eventually causing the motor to fail to work, so the heat dissipation performance of the controller Good or bad is directly related to the service life of the controller. [0003] Limited by material cost and material characteristics, the current temperature resistance of the capacitor body can only reach 105°C, and the temperature resistance of other components inside the motor con...
