Assembly structure of inverter power unit and modular power unit using same

逆变器功率单元的组装结构及使用其的模块化功率单元

Abstract

The invention discloses an assembly structure of an inverter power unit, comprising a capacitor, a power module, a radiator and a fan, wherein the radiator comprises a base plate and a plurality of radiating tooth pieces connected with the lower surface of the base plate and used for heat radiation; the capacitor is arranged on the power module; the power module is installed on the upper surface of the base plate; and the fan is installed at the bottom of tooth pieces, is parallel to the power module and blows right against the tooth pieces. In the invention, the three-dimensional structure design of sequentially placing the capacitor, the power module, the radiator and the fan is utilized to enable the structure to be more compact and the installation area to be small, meanwhile, due to using the mode that the fan vertically blows the tooth pieces, the invention has good heat radiation effect and improved use ratio and reliability of the power module. In addition, the invention also provides a modular power unit designed by using the assembly structure design.
一种逆变器功率单元的组装结构,包括电容、功率模块、散热器以及风扇。其中,所述散热器包括基板以及与基板的下表面相连、用于散热的多条齿片。所述电容设置在所述功率模块上。所述功率模块安装在所述基板的上表面。所述风扇安装在齿片的底部,且与所述功率模块平行设置,正对齿片吹风。本发明通过电容、功率模块、散热器以及风扇的依次顺序放置的立体化结构设计,使结构更为紧凑,安装面积小,且,采用风扇对齿片垂直吹风的模式,散热效果好,同时提高了功率模块的使用率和可靠性。另外,本发明还提供一种使用该组装结构设计的模块化功率单元。
