AI Technical Summary
Technical Problem
The existing DC charging piles have a cumbersome filter fixing method, which requires tools and is inconvenient to install and remove.
Method used
An automatic heat dissipation device for DC charging piles was designed. The filter screen can be quickly disassembled and assembled by rotating the combination structure of the metal strip and the pressure frame. The connecting sleeve can be pushed by the elastic deformation and bending of the metal strip to achieve tool-free disassembly and assembly.
Benefits of technology
It enables quick replacement and cleaning of the filter screen, simplifies the operation process, and improves maintenance efficiency.

Abstract
This utility model proposes an automatic heat dissipation device for DC charging piles, relating to the field of charging pile heat dissipation technology. It includes a base, comprising a housing and an outer cover, the outer cover being rotatably connected to the housing. When replacing the filter, the device rotates a metal strip, causing it to elastically deform and move away from the stop block's limit. Then, the metal strip and pressure frame are rotated, allowing the filter to be removed. After cleaning, the filter is placed back on the mounting plate. The protruding plate on the pressure frame is then fastened into the ring. Rotating the metal strip again causes it to elastically deform, generating elastic force. The bending portion on the metal strip pushes the connecting sleeve and pressure frame, causing the protruding plate to move within the ring. The elastic force of the metal strip tightly fastens the pressure frame to the filter. Finally, the metal strip is fastened under the stop block. This device allows for quick installation and removal of the filter without the need for tools.
