AI Technical Summary

Technical Problem

Traditional electrical connectors have limited heat dissipation efficiency and are difficult to dissipate heat quickly in the event of a sudden increase in current load or in harsh environments. This can lead to a sharp rise in terminal temperature, potentially causing thermal runaway and affecting equipment safety.

Method used

The composite heat dissipation component uses a high thermal conductivity ceramic layer and a special insulation sleeve. The high thermal conductivity ceramic layer quickly absorbs and evenly conducts heat, while the special insulation sleeve guides the heat to a designated heat dissipation path. Combined with a micro heat dissipation fin array and ventilation grilles, directional heat dissipation is achieved.

Benefits of technology

It achieves a highly sensitive thermal response, conducts heat quickly and evenly, improves heat dissipation efficiency, avoids internal heat diffusion, ensures stable operation of electrical connectors under high power, and enhances reliability and power carrying capacity.
