[0033] Please refer to Figures 1-6 , this embodiment provides a technical solution:

[0034] A heat-conducting paper includes a cardboard body 2, a limiting ring 1 is sleeved on the outer wall of the cardboard body 2. The cardboard body 2 includes a heating layer 20, insulating pads 21 are arranged on both sides of the heating layer 20, conductive layers 22 are arranged on the outer sides of the insulating pads 21, an electric heating wire 200 is arranged in the middle of the heating layer 20, and a connection terminal post 201 is connected to the end of the electric heating wire 200.

[0035] Furthermore, the heating layer 20 is composed of a carbon fiber material combination.

[0036] In the present utility model, the heating layer 20 made of carbon fiber material helps to heat evenly.

[0037] Specifically, the heating wire 200 is in a curved shape, the heating wire 200 is adhesively fixed to the heating layer 20, and the end of the heating wire 200 is electrically connected to the terminal post 201.

[0038] In the present utility model, the heating wire 200 helps to connect with an external power supply through the terminal post 201, so as to realize the energization and heating cooperation of the heating wire 200.

[0039] It should be noted that the width of the outer wall of the insulating pad 21 is adapted to the width of the outer wall of the heating layer 20, and the bottom of the insulating pad 21 is adhesively fixed to the outer side surface of the heating layer 20.

[0040] In the present utility model, the insulating pad 21 is made of virgin rubber. The virgin rubber has more stable performance, longer service life, and no peculiar smell. With the cooperation of the insulating pad 21, the influence of conductive transmission on both sides of the heating layer 20 is reduced.

[0041] Furthermore, a plurality of protrusions 210 are provided on the outer wall of the insulating pad 21. The protrusions 210 are equally spaced, and the protrusions 210 and the insulating pad 21 are of an integrally formed structure.

[0042] In the present utility model, setting a plurality of protrusions 210 increases the contact area of the outer side surface of the insulating pad 21, which further helps the insulating pad 21 to be fitted and installed with the conductive layer 22.

[0043] Specifically, the conductive layer 22 is composed of a mixture of carbon fiber and plant fiber materials. At the position corresponding to the protrusions 210 on the bottom of the conductive layer 22, a groove 220 is provided. The width of the inner wall of the groove 220 is adapted to the width of the outer wall of the protrusions 210, and the bottom of the conductive layer 22 is tightly adhesively combined with the outer wall of the insulating pad 21.

[0044] In the present utility model, the conductive layer 22 composed of a mixture of carbon fiber and plant fiber materials helps to perform stable conductive cooperation and reduce the construction cost. The groove 220 and the protrusions 210 are inserted and matched to realize the stable combined installation of the conductive layer 22 and the insulating pad 21. With the cooperation of the conductive layer 22, the charge transfer on the outer wall is facilitated.

The connection terminal post 201 extends out of the heat - generating layer 20. The insulating pad 21 is tightly bonded and combined with the heat - generating layer 20. The conductive layer 22 is inserted and matched with the protrusion 210 on the insulating pad 21 through the groove 220, which increases the stability of the combination of the conductive layer 22 and the insulating pad 21.

[0048] The connection terminal post 201 is electrically connected to an external power source through a wire. The heating wire 200 is powered on and continuously heats the heat - generating layer 20 evenly, and then heats the insulating pad 21 and the conductive layer 22 to achieve overall heat - generating cooperation. With the cooperation of the insulating pad 21, the damage to the internal heat - generating layer 20 caused by conduction when the conductive layer 22 contacts an external conductive element is reduced, thereby extending the overall service life. With the cooperation of the limiting ring 1, it helps to protect the side wall of the cardboard body 2 and is conducive to long - term use. The heat - generating layer 20 made of heat - conductive silicone material is convenient for uniform heating. The conductive layer 22 made of carbon fiber and plant fiber materials is convenient for conduction, has a low manufacturing cost, is convenient for bending and using, and has a wide range of applications.
