Abstract

The invention discloses a bi-side heat radiation electric car power module which comprises a first heat sink, a chip welded on a position corresponding to the first heat sink, and a second heat sink, wherein the chip and / or the first heat sink is electrically connected with the corresponding ports of the second heat sink. The bi-side heat radiation electric car power module further comprises a power terminal and a control terminal connected with the first heat sink, and a sealing housing. A bi-side radiator is integrated on the power module. Direct liner plate cooling and bi-side heat radiation is realized, and the heat radiation performance of the power module is improved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a double-sided heat dissipation electric vehicle power module. Background technique [0002] With the continuous improvement of people's awareness of environmental protection, energy saving and emission reduction, the development of a new generation of non-polluting, high-performance hybrid vehicles and pure electric vehicles has become a hot spot for research institutions and companies all over the world. The power electronic module represented by IGBT is one of the core components of motor drive and control in electric vehicles. As people's performance requirements for automotive motor inverters are getting higher and higher, higher requirements are also put forward for power electronic modules in terms of power density, operating temperature, efficient heat dissipation, and power conversion efficiency.
