Novel motor controller device integration structure

Abstract

The invention discloses a novel motor controller device integrated structure, which includes an integrated structure housing, a water channel heat dissipation structure is arranged inside the integrated structure housing, an IGBT device of the motor controller is installed on the upper end of the water channel structure, and the integrated structure housing is in the Below the heat dissipation structure of the water channel, there is a cavity structure required for placing the capacitor core and its busbar copper bars. The capacitor core and its busbar copper bars are fixed in the cavity structure of the integrated structure shell, and the remaining space in the cavity structure is injected with epoxy resin glue. After curing, the installation and positioning dimensions of the capacitor core and bus bar copper bars are guaranteed. The structure of the present invention is small in size and exists independently. The capacitor core is injected onto the aluminum alloy shell of a specific structure through epoxy resin glue, and the heat of the capacitor is directly transmitted to the aluminum alloy shell for effective heat dissipation; the aluminum alloy shell adopts an integrated It is cast and formed, and its solid part integrates the water channel structure, which can not only meet the heat dissipation requirements of the IGBT original components, but also provide a heat dissipation environment for the capacitor at the same time.

Description

technical field [0001] The invention relates to a motor controller, in particular to a novel motor controller IGBT cooling channel and capacitor integrated structure. Background technique [0002] In the current technical scheme of the motor controller, the capacitor is an independent device, and its shell adopts a non-metallic structure to ensure the insulation effect of the shell, but the thermal resistance is relatively large. After being assembled with the shell, the heat dissipation performance of the capacitor is slightly poor, affecting The overall performance of the controller; the IGBT water channel is in the controller shell, which makes the structure of the entire controller shell more complicated; the capacitor structure, bus terminal block, IGBT water channel, etc. are all independent individual structures, which are connected and fixed on the controller through standard parts In the housing of the device, the realization of the entire function is completed.

[0002] In the current technical scheme of the motor controller, the capacitor is an independent device, and its shell adopts a non-metallic structure to ensure the insulation effect of the shell, but the thermal resistance is relatively large. After being assembled with the shell, the heat dissipation performance of the capacitor is slightly poor, affecting The overall performance of the controller; the IGBT water channel is in the controller shell, which makes the structure of the entire controller shell more complicated; the capacitor structure, bus terminal block, IGBT water channel, etc. are all independent individual structures, which are connected and fixed on the controller through standard parts In the housing of the device, the realization of the entire function is completed. Due to the relatively large size of the housing, the processing complexity of the housing is relatively high, and it is difficult to ensure a high manufacturing yield; when assembling, assemble the IGBT and capacitor according to the assembly requirements It is difficult to realize the pre-installation of sub-assemblies into the controller shell, and the production efficiency cannot be further improved
