Abstract

The invention relates to the technical field of power electronic devices, in particular to a power module, a motor controller and a vehicle. The power module comprises at least two power units and a pressing block, the two adjacent power units are defined as a first unit and a second unit, notches are formed in the opposite side edges of the first unit and the second unit, the two notches define a mounting through hole, and the pressing block comprises a pressing block body and a positioning part arranged on one surface of the pressing block body in a protruding mode. The pressing block main body is pressed on the adjacent first unit and second unit, and the positioning part penetrates through the mounting through hole to be positioned and fixed on an external heat dissipation device. Through the structural design of the power unit and the pressing block, the power unit is installed on the external heat dissipation device, the overall size is not increased, the overall compactness of the power module is improved, through positioning of the positioning part, the situation that accurate installation cannot be achieved before positioning is avoided, and automatic assembly of the power module is improved.

Description

technical field [0001] The present invention relates to the technical field of power electronic devices, in particular to a power module, a motor controller and a vehicle. Background technique [0002] A power module is a power drive product that combines power electronics and integrated circuit technologies. [0003] For example, the controller of a new energy electric vehicle includes several power modules, and controls the rotation of the main motor through these power modules. [0004] In electrical installations such as inverters, there is less and less space for molding power modules. Generally, when a power module is provided with a heat sink, it is necessary to pass through a corresponding fixing area of ​​the power module through a fixing member such as a pressing block, so as to fix the power module to the heat sink. The fixed area of ​​the power module will occupy the space of the power module, so that the volume of the power module is relatively large. When mul...
