AI Technical Summary

Technical Problem

Dust easily accumulates on the surface of the heat sink fins of existing millimeter-wave radar devices, affecting heat dissipation and making maintenance inconvenient and cleaning difficult to perform in a timely manner.

Method used

A self-cleaning heat dissipation structure was designed, including inclined heat dissipation fins and a cleaning mechanism. The rotating mechanism automatically cleans dust during the heat dissipation process. The cleaning frame is pushed to slide along the fins by rotating impeller and protruding plate, and automatic cleaning is achieved in combination with cleaning brush.

Benefits of technology

This ensures that the heat dissipation fins are automatically cleaned before each operation, improving heat dissipation efficiency, reducing maintenance costs, and extending the service life of the device.
