AI Technical Summary

Technical Problem

Existing PoE switches lack auxiliary heat dissipation structures during long-term testing, resulting in inefficient heat dissipation at the connection points and reduced test stability.

Method used

An electronic load tester for PoE testing of switches was designed, which includes components such as a positive pressure mechanism and a protection mechanism. A micro-positive pressure environment is formed by a current-guiding component and a fan, and combined with heat dissipation and heat conduction components, it achieves auxiliary heat dissipation and protection at the connection point.

Benefits of technology

It improves the stability of switch PoE during long-term testing, and ensures the reliability and efficiency of the testing process by combining heat dissipation and protection structures.
