Abstract

The invention provides a three-phase copper bar and an electric drive assembly; the three-phase copper bar comprises a base, three copper bars and at least one heat transfer sheet; the three copper bars and the at least one heat transfer sheet are installed on the base, the heat transfer sheet is located between the base and the copper bars, and the base is provided with a through hole for at least a part of the heat transfer sheet to penetrate out. The electric drive assembly comprises a motor and a controller, and a three-phase high-voltage power supply output end of the controller is electrically connected with a three-phase terminal of the motor through the three-phase copper bar. Heat flow generated on the copper bars can be guided out through the heat transfer sheet, so that the temperature of the copper bars can be effectively reduced, the heat dissipation effect of the copper bars is improved, and the problem of thermal field coupling between the motor and the controller can besolved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a three-phase copper bar and an electric drive assembly. Background technique [0002] The rapid development of new energy vehicles puts forward high requirements on the high power output of electric drive assembly products. Decompose the power demand to the internal parts of the electric drive assembly. The high power output of the electric drive assembly puts forward higher requirements on the power output of the motor and the current capacity of the controller, and this power demand leads to more interaction between the motor and the controller. Great heat. However, limited by the tolerance temperature of the components in the motor and the controller, the high-power electric drive assembly not only needs to improve the heat dissipation of the motor and the controller itself, but also needs to consider the high-voltage connectors connecting the motor and the control...
