Large-power module cooling structure of electric vehicle controller

Abstract

The invention relates to a large-power module cooling structure of an electric vehicle controller, which comprises at least one heat pipe and a radiation bottom plate which is arranged on a large-power module, wherein the heat pipe has an inner cavity in which a phase-change material is provided; the heat pipe comprises a heat pipe main body and at least one extension part; the heat pipe main body is inserted into the radiation bottom plate and tightly contacted with the radiation bottom plate; the extension part is communicated with the heat pipe main body and extends and exposes out of the radiation bottom plate from the heat pipe main body; preferably, two extension parts are arranged at the two ends of the heat pipe main body respectively; the heat pipe main body is horizontally inserted into the radiation bottom plate; and the large-power module cooling structure also comprises an auxiliary radiation device which is arranged in combination with the extension parts for radiating heat of the extension parts. The large-power module cooling structure of the electric vehicle controller of the invention has ingenuous design and improves the radiation, stability and reliability of the large-power module, so that the performance of the controller and the whole vehicle performance are improved. Moreover, the large-power module cooling structure of the electric vehicle controller has a simple structure and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of electric vehicle drive systems, in particular to the technical field of electric vehicle electric drive system motor controllers, in particular to a high-power module cooling structure for electric vehicle controllers. Background technique [0002] As environmental protection issues are getting more and more attention from the society, it has become a general trend to replace fuel vehicles with new energy vehicles, and pure electric vehicles have immediately gained unprecedented development opportunities. Constrained by battery energy supply, electric vehicles need to have the characteristics of small size and light weight. As the control part of the main power source of electric vehicles, the drive motor controller has a direct impact on the performance of the whole vehicle. Therefore, the drive motor controller must have the characteristics of simple structure, small size, light weight, low loss, and hi...
