AI Technical Summary

Technical Problem

Existing power cables have poor heat dissipation performance, especially in important locations such as high-rise buildings, subways, tunnels, power plants, and nuclear power plants, where static heat dissipation methods cannot meet the requirements for efficient heat dissipation.

Method used

A power cable with a built-in heat dissipation unit was designed, including a cable core, an outer connecting sleeve, a heat dissipation unit, and a drive unit. By combining an annular telescopic airbag, a positioning annular plate, a squeezing annular plate, an air inlet pipe, and an exhaust pipe, the drive unit controls the periodic movement of the squeezing annular plate to achieve airflow replacement and realize active heat dissipation.

Benefits of technology

This improves the heat dissipation and heat conduction of the cable, enabling the periodic replacement of cold and hot airflows and enhancing the cable's heat dissipation performance.

Abstract

This invention discloses a power cable with a built-in heat dissipation unit, including a cable core, an outer connecting sleeve, a heat dissipation unit, and a drive unit. The invention periodically compresses a moving ring using a rotating disk. The moving ring, via a guide rod, drives multiple compression ring plates axially, causing the compression ring plates to compress and exhaust air from an annular telescopic airbag. The airflow is then discharged through an exhaust pipe, allowing hot air to escape. When the rotating disk rotates and separates from the moving ring, a pressure return spring elastically presses against a return block, causing the return block to slide back within a positioning groove. This return block then drives the compression ring plates to move back to their original positions. The compression ring plates then pull on the annular telescopic airbag, causing it to draw in air. External cold air enters through an intake pipe, thus periodically replacing the hot air with cold air, improving heat dissipation and thermal conductivity.
