Abstract

The invention discloses a DC (direct current) / DC controller-motor controller integrating structure of an electric vehicle, which is characterized in that the motor controller at the upper part and the DC / DC controller at the lower part are assembled in one shell in an integrating way, an interlayer is arranged between a bottom plate of the motor controller and a top plate of the DC / DC controller, and the interlayer is communicated with a water inlet pipe and a water outlet pipe respectively at the side parts to form a cooling water channel. The DC (direct current) / DC controller-motor controller integrating structure of the electric vehicle is compact and reasonable in structure and good in radiating effect.

Description

technical field [0001] The invention relates to the structural arrangement of a DC / DC controller and a motor controller of an electric vehicle. Background technique [0002] Based on the requirements of energy and environmental protection, electric vehicles have become another main direction of the development of the automobile industry. Both the motor controller and DC / DC controller in electric vehicles are key components. The motor controller is used to control the forward, backward and electric states of the motor. Its heat dissipation function is the guarantee for the reliable operation of the motor controller. [0003] In the prior art, the motor controller and the DC / DC controller in the electric vehicle are two mutually independent units, each equipped with a heat dissipation system. This structural form brings disadvantages such as large space occupation, large volume and heavy weight. Contents of the invention [0004] The present invention provides an integrated...
