AI Technical Summary

Technical Problem

During use, due to heat accumulation in the cable harness, the heat dissipation speed is slow when the current passes, which increases safety risks, especially when the car is charged.

Method used

The charging wire harness design is adopted that includes an insulating layer, conductor, filler and cooling tube. The cooling tube stores or passes the cooling medium in real time. The filling parts use PE, PP or Teflon materials, and metal-made support members are provided on the outer walls of the conductor and cooling tube to improve heat dissipation and structural strength.

Benefits of technology

Through the cooperation of the filler and the cooling medium, the heat dissipation effect of the wiring harness is significantly improved, the current through the cable harness is increased, and the safety risks during the wiring harness are reduced. The metal support further enhances the stability and heat dissipation of the wiring harness.
