The current heat dissipation component of the power distribution cabinet is not easy to disassemble and install from the cabinet door of the power distribution cabinet. When the heat dissipation component is maintained, the design that is not easy to disassemble reduces the maintenance efficiency of the heat dissipation component. In the corresponding designed group of easy-to-disassemble components, when the heat dissipation fan needs to be disassembled from the cabinet door of the distribution cabinet for maintenance, the wiring harness connection on the wiring harness interface is first released, and then the handle is pulled downward. The handle will drive the vertical rod and the limit plug rod to move downward, and the limit plug rod will be pulled out of the slot of the U-shaped frame, and the spring outside the vertical rod will accumulate force and contract. At this time, the external mounting frame is directly pulled in the direction away from the cabinet door of the distribution cabinet, and the external mounting frame will slide out from the guide rail frame and then be removed. When the maintenance is completed and the heat dissipation fan is installed, it can be removed by pulling The handle is moved downward to allow the limit rod to be pulled out of the groove of the U-shaped frame, the spring is charged and contracted, and then the external mounting frame is placed in the guide rail frame, and the external mounting frame is pushed forward to move the external mounting frame until one side of the external mounting frame contacts the cabinet door of the distribution cabinet. At this time, the external mounting frame will be located on one side of the ventilation hole on the cabinet door of the distribution cabinet. Release the pull on the handle, the spring releases the stored force, and the limit rod will be reinserted into the groove of the U-shaped frame, and one side of the limit rod will contact the side protrusion.

The design of the disassembly and assembly component group 02 uses a structure that is convenient for disassembly and installation of the cooling fan 12. In the maintenance work of the cooling fan 12, the disassembly and installation process is greatly simplified, thereby improving the maintenance efficiency.At present, the cooling fan 12 of the heat dissipation component lacks a dust structure that is easy to replace. The dust screen on the existing fan is not easy to disassemble and clean after being used for a period of time, which increases the time consumption of maintenance and cleaning. In the corresponding designed dust-proof component group 03, the dust-proof net 321 can be blocked outside the air-permeable circular hole of the distribution cabinet door 11 to filter and block the dust in the air flow and prevent dust from entering the distribution cabinet.

When the air flow passes through the air-permeable circular holes on the cabinet door 11, it can only pass through the dustproof net 321. The design of this dustproof component group 03 improves the cleaning efficiency of the dustproof net 321. When cleaning, the dustproof net assembly 32 can be directly removed and inserted back into its original position after cleaning.
