[0002] Outdoor industrial distribution cabinet is a kind of equipment used for power distribution and control, usually installed in outdoor environment to provide power for industrial equipment, buildings or facilities. It is widely used in industrial automation, warehousing and construction sites. Since outdoor industrial distribution cabinet is installed in outdoor environment, it is easy to freeze between the door frame and the cabinet body of the distribution cabinet when used for a long time in winter. It is difficult to open the door frame of the distribution cabinet during subsequent maintenance, so it is necessary to de-ice the door frame and the cabinet body of the distribution cabinet.

[0003] Traditional deicing operations mostly use hot water to pour out the ice between door frames and cabinets. After the ice layer is melted with hot water, other tools are used to clean the remaining ice until the door frame can be opened.
