The invention discloses a converter, permanent magnet traction equipment, a railway vehicle and a power unit assembly, the converter is applied to the railway vehicle, the converter comprises a box body and the power unit assembly, the power unit assembly is installed in the middle of the box body in the length direction, the power unit assembly comprises a radiator, the radiator comprises a plurality of radiating fins, and the radiating fins are arranged in the box body. The plurality of radiating fins are stacked at intervals along the height direction of the box body and extend along the width direction of the box body, so that the power unit assembly is arranged perpendicular to the driving direction of the railway vehicle, the layout of the power unit and the radiator in the box body can be changed, the width and the weight of the whole equipment can be greatly reduced, and the power unit assembly is more convenient to use. The size and the weight of the converter are further reduced, better miniaturization and lightweight design of the converter is realized, and the practicability and the reliability of the converter are improved. According to the technical scheme, the size and weight of the converter are reduced, and the miniaturization and lightweight design of the converter is achieved.
本发明公开一种变流器、永磁牵引设备、轨道车辆和功率单元组件,其中,变流器应用于轨道车辆,变流器包括:箱体和功率单元组件,功率单元组件安装于箱体的长度方向的中间部分,功率单元组件包括散热器,散热器包括多个散热翅片,多个散热翅片沿箱体的高度方向间隔层叠设置且多个散热翅片沿箱体的宽度方向延伸设置,从而使得功率单元组件垂直于轨道车辆的行车方向设置,可以改变功率单元和散热器在箱体内的布局,能够极大的缩小整个设备的宽度和重量,进一步减少变流器的体积和重量,实现变流器更好的小型化、轻量化设计,提高了变流器的实用性和可靠性。本发明技术方案旨在减少变流器的体积和重量,实现变流器的小型化、轻量化设计。
