AI Technical Summary

Technical Problem

Traditional high-voltage wiring harness insulation protection devices for new energy vehicles lack heat dissipation mechanisms, causing the wiring harness temperature to rise during high-voltage operation. High temperatures accelerate the aging of insulation materials, reduce insulation performance, and increase the risk of leakage and safety hazards.

Method used

An insulation protection device was designed, which includes a housing, a heat dissipation mechanism, a fixing mechanism, and a ventilation mechanism. It uses components such as a cooling box, heat pipes, and axial fans to achieve active heat dissipation, and combines magnetic blocks and sliding column clamps to fix the cables and ensure a stable connection.

Benefits of technology

Through active heat dissipation and stable connection, the heat dissipation performance of the insulation protection device and the stability of cable fixation are significantly improved, extending the service life of the equipment, reducing the risk of leakage, and improving safety.
