[0016] As Figs. 1-2As shown, a graphene aluminum foil heating mat includes a ground mat 100, a heating body 200 and a cover layer 300, the ground mat 100, the heating body 200 and the cover layer 300 are sequentially stacked from bottom to top, the heating body 200 includes a mirror surface reflecting film 1, a heating cable 2, a graphene paper 4 and an upper aluminum foil 5, the mirror surface reflecting film 1, the heating cable 2, the graphene paper 4 and the upper aluminum foil 5 are sequentially adhered to form an integral body, the heating cable 2 is arranged in an S shape, the inner side of the bending of the heating cable 2 is provided with a heat dissipation fin 6, the heat dissipation fin 6 includes a corrugated pipe sleeve 61 and a plurality of diffusion sheets 62, the corrugated pipe sleeve 61 is sleeved on the bending of the heating cable 2, one end of the diffusion sheet 62 is detachably connected with the corrugated pipe sleeve 61, and the other end extends and is provided in the gap between the heating cables 2. Specifically, in this embodiment, the ground mat 100 serves as a pad plate to prevent the heating body 200 from directly contacting the cement floor in the room, thereby effectively reducing the wear of the heating body 200, ensuring the safety of the heating body 200 and prolonging the service life of the heating body 200. Moreover, the ground mat 100 can be directly used to fixedly connect the heating body 200, and the connection can be achieved by adhesion or by means of buckles. The cover layer 300 is arranged on the surface of the heating body 200 to solve the problem of poor wear resistance of the heating body 200, and the cover layer 300 has good wear resistance and heat conductivity. Furthermore, in order to improve the construction efficiency and reduce the construction difficulty, the heating body 200 is integrally formed when it is delivered from the factory, and can be directly laid on the construction site and connected to the power supply. The heating body 200 includes the mirror surface reflecting film 1, the heating cable 2, the graphene paper 4 and the upper aluminum foil 5, the mirror surface reflecting film 1 can be used to reflect the heat radiation generated by the heating cable 2 upward, thereby preventing the heat generated by the heating cable 2 from being conducted to the lower floor and causing heat loss and a decrease in the heat in the room. The heating cable 2 is arranged in an S shape to increase the layout area and generate more heat in a unit area after being powered on. The graphene paper 4 is attached to the heating cable 2, and the graphene paper 4 conducts heat, which can uniformly conduct and disperse the heat generated by the heating cable 2, thereby preventing the heat from gathering around the heating cable 2 and causing overheating and damage to the heating cable 2. An upper aluminum foil 5 is attached to the outer surface of the graphene paper 4, the upper aluminum foil 5 is used to protect the graphene paper 4 from being directly exposed and easily damaged, and can enhance the heat conduction performance of the graphene paper 4.Further, because the larger the diameter of the heating cable 2, the higher the heating power, but when the diameter of the heating cable 2 exceeds a certain threshold, because the heating cable 2 is S-shaped, the space between the two heating cables 2 is hollow, and the gravity of the furniture installed in the room will inevitably cause the heating cable 2 to be pressed, which will easily cause the heating cable 2 to be crushed and deformed, and in severe cases, it may cause the insulation layer of the heating cable 2 to be damaged. When the heating cable is pressed and deformed, the deformed heating cable will accelerate the aging process under the action of continuous high temperature and mechanical stress. The internal conductor may be squeezed or stretched, causing the cross-sectional area of the conductor to change, thereby affecting the resistance of the conductor. And the decline in insulation performance may cause electrical faults such as short circuits or electrical leakage, posing a threat to the safe operation of the floor heating system. In order to avoid the above problems, we set a heat dissipation fin 6 at the inner bending position of the heating cable 2, including a corrugated pipe sleeve 61 and a plurality of fins 62. When assembling, the corrugated pipe sleeve 61 is bendable, so it can bend synchronously with the heating cable 2, and the fins 62 are arranged on the inner side to extend, so that the fins 62 act as a support between the two parallel short heating cables 2, filling the space between the short heating cables 2 and avoiding pressure on the heating cable 2 itself. In addition, the corrugated pipe sleeve 61 is sleeved on the bending position of the heating cable 2, which protects the bending position of the heating cable and avoids excessive wear at the bending position. When powered on, the bending position of the heating cable 2 is more likely to cause heat accumulation, and the corrugated pipe sleeve 61 and the fins 62 work together to more easily conduct heat away from the bending position, not just relying on the graphene paper 4 to conduct heat, thereby enhancing the heat conduction performance of the bending position of the heating cable 2.

[0017] As shown in Fig. 2 , the fins 62 are provided with an insert 621, and specifically, the insert 621 can increase the support and heat conduction area.

[0018] As shown in Fig. 2 , the inserts 621 on the two adjacent fins 62 are crossed with each other, effectively utilizing the limited space between the two parallel short heating cables 2, arranging more inserts 621 to fill the blank area and provide better support performance.

[0019] Specifically, the cover layer 300 is an aluminum plastic plate, which can quickly transfer heat to the ground when the floor heating system is running, improving the heating efficiency of the floor heating. Compared with traditional materials such as cement or gypsum board, the aluminum plastic plate has obvious advantages in heat conduction performance. It can withstand a certain degree of friction and wear and tear, and is not easy to scratch or deform.

[0020] As shown in Fig. 1As shown, the heating body 200 and the covering layer 300 are further provided with a fire-retardant sheet 400, the fire-retardant sheet 400 can effectively inhibit the occurrence and spread of fire when the floor heating is out of control. In the case of high temperature, the fire-retardant material can reduce the propagation speed of the flame, provide more time for escape and fire extinguishing, and improve the safety factor of the floor heating.

[0021] As an optional embodiment, the floor mat 100 is made of flexible neoprene rubber pad.

[0022] The above embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the application patent. It should be pointed out that, for the ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the application patent should be subject to the appended claims.
