Abstract

The invention relates to a sealed integrated power unit module. The power unit module comprises a heat dissipation substrate, a full-closed protective shell, a cable insulation protective sleeve and apower unit. The power unit is arranged on the heat dissipation substrate in an integrated mode, the full-closed protective shell is arranged on the heat dissipation substrate in a sealed mode, the cable insulation protective sleeve is arranged on the full-closed protective shell, and a cable of the power unit is connected with the outside world through the cable insulation protective sleeve. In the invention, heat generated by the power unit is dissipated through the bottom heat dissipation substrate; a main power cable is protected through a cable protective sleeve and is externally connected through the full-closed protective shell, the integrated power unit is completely isolated from an external environment through an enclosed structure, and power electronic devices in the integratedpower unit can be protected to operate under severe environmental conditions.

Description

technical field [0001] The invention relates to the field of power electronic equipment, in particular to a sealed integrated power unit module. Background technique [0002] Power electronic devices are widely used in different fields such as aerospace, ship electrical, mining production, and rail transportation. However, in some application environments, the working environment of power electronic devices is very harsh, often due to high salt spray, high humidity and other environments that cause serious aging of power electronic devices, which affects the overall life of the equipment in mild cases, and even causes explosions in severe cases. Therefore, how to effectively ensure the stable and reliable operation of power electronic devices and prolong the life of equipment has become the focus of widespread attention. Contents of the invention [0003] In order to solve the existing technical problems, the present invention provides a sealed integrated power unit modul...
