Novel shared shell of motor controller and film capacitor and motor controller

Abstract

The invention relates to the technical field of motor controllers, in particular to a novel shared shell of a motor controller and a film capacitor and a motor controller. The novel shared shell of amotor controller and a film capacitor includes a shell body. A water inlet and a water outlet are arranged in the side wall of the shell body. At least one cold water input pipe string and at least one cold water output pipe string are arranged in the shell. The upper end of each cold water input pipe string and the upper end of each cold water output pipe string extend upward along the height direction of the shell body. The at least one cold water input pipe string is provided with a cold water outlet at the upper end. The at least one cold water output pipe string is provided with a cold water inlet at the upper end. Multiple IGBT connection columns are also arranged in the shell body. A capacitor body installation gap is arranged between the inner wall of the shell body on one hand andthe at least one cold water input pipe string, the at least one cold water output pipe string and the IGBT connection columns on the other hand. Through the design of the shell, the film capacitor inthe motor controller can be cooled by water, the working environment of the film capacitor can be improved, the high temperature resistance level of the film capacitor can be increased, and a stronghardware support is provided for the improvement of the upper power limit 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 and a film capacitor sharing a shell and the motor controller. 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 film capacitors can only reach 105°C, and the temperature resistance of other components inside the motor controller can r...
