AI Technical Summary

Technical Problem

In existing exhaust heaters, the electrical insulation between the heat conductor and the support remains unstable, leading to the risk of short circuits and affecting the stability of the heat conductor and heating efficiency.

Method used

The connecting elements of the connecting device and the insulating support unit are fixedly connected to the heat conductor and the support sleeve by means of material locking or friction locking. The gap is filled with insulating material to ensure electrical insulation between the heat conductor and the support and avoid electrical short circuit.

Benefits of technology

This achieves stable electrical insulation of the heat conductor on the support, improves mechanical stability and heating efficiency of the heat conductor, and resists moisture penetration and chemical action.
