DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0021] Embodiment one

[0022] Referring to Figure 1 , Figure 2 A graphene electric heating film wall surface warmer, comprising a plurality of frames 1, the plurality of frames 1 are assembled through connecting corner pieces 3, heat preservation plates 4 are installed on the inner sides of the plurality of frames 1, a plurality of fixing strips 5 are arranged on one side of the heat preservation plates 4, single-sided adhesive composite films 7 are attached to the outer sides of one end of the plurality of fixing strips 5 through heat conducting adhesive tapes 6, graphene electric heating films 8 are attached to the outer sides of one end of the single-sided adhesive composite films 7, insulation and flame retardant layers 13 are attached to the outer sides of one end of the graphene electric heating films 8 through double-sided hot melt adhesive films 12, and decorative layers 14 are attached to the outer sides of one end of the insulation and flame retardant layers 13 through double-sided hot melt adhesive films 12.

[0023] Further, the graphene electric heating film 8 comprises PET polyester film insulation layers, synthetic resin layers, metal current-carrying strip layers, graphene conductive adhesive layers, graphene paste layers and PET polyester film insulation layers arranged in sequence.

[0024] Still further, referring to Figure 2 , Figure 5 , one side of the frame 1 is provided with a power supply interface 11, the power supply interface 11 and the graphene electric heating film 8 are electrically connected through the wire 9, the outside of the wire 9 is electrically connected with a plurality of temperature sensing elements 10, and the temperature sensing elements 10 are attached to the graphene electric heating film 8.

[0025] Still further, referring to Figure 3 , Figure 4 , the two groups of frames 1 located on the upper and lower sides are both provided with a plurality of air flow holes 2, and the plurality of air flow holes 2 and the plurality of fixed strips 5 are arranged alternately.

[0026] Further, the heat preservation plate 4 is an aluminum foil heat preservation plate 4, and the insulating flame-retardant layer 13 is an epoxy resin plate.

[0027] Further, the heat preservation plate 4 is a glass fiber heat preservation plate 4, and the insulating flame-retardant layer 13 is a glass fiber plate.

[0028] Working principle:

[0029] Referring to Figure 1 , Figure 2 , the external power supply line is connected with the power supply interface 11 and provides electric energy, the electric energy received by the power supply interface 11 is transmitted to the graphene electric heating film 8 through the wire 9, the graphene electric heating film 8 starts to work and emits heat after receiving the electric energy, a part of the heat is conducted to the heat-conducting adhesive tape 6 through the single-sided adhesive composite film 7, the heat-conducting adhesive tape 6 further conducts the heat to the fixed strip 5, and then the fixed strip 5 conducts the heat to the heat preservation plate 4; another part of the heat is transmitted to the insulating flame-retardant layer 13 through the double-sided hot melt adhesive film 12 (the double-sided hot melt adhesive film 12 is located between the graphene electric heating film 8 and the insulating flame-retardant layer 13), and then the insulating flame-retardant layer 13 transmits the heat to the double-sided hot melt adhesive film 12 (the double-sided hot melt adhesive film 12 is located between the insulating flame-retardant layer 13 and the decorative layer 14), and finally the double-sided hot melt adhesive film 12 transmits the heat to the decorative layer 14, and the decorative layer 14 radiates the heat outward.

[0030] Based on the heat transfer process, when in use, one side of the heat preservation plate 4 should be arranged as the wall sticking side, and one side of the decorative layer 14 should be arranged as the display side. Since the graphene electric heating film 8 needs to pass through the fixed strip 5 when transferring heat to the heat preservation plate 4, and there is a gap between the plurality of fixed strips 5, the contact area of the fixed strip 5 and the heat preservation plate 4 is reduced, and the heat contact type transmission efficiency is reduced. Finally, most of the heat will gather in the gap between the plurality of fixed strips 5. Since the air flow holes 2 are arranged in the gap between the plurality of fixed strips 5 in the upper and lower corresponding frames 1, the gap between the plurality of fixed strips 5 and the air flow holes 2 form a chimney effect, so that the cold air naturally flows into the gap between the plurality of fixed strips 5 from the air flow hole 2 at the bottom. After the cold air in the gap between the plurality of fixed strips 5 is heated by the graphene electric heating film 8, it flows out through the air flow hole 2 at the upper end, realizing air circulation. Based on the air circulation process, the heat preservation plate 4 is arranged as the wall sticking side, so as to avoid the air entering the gap between the plurality of fixed strips 5 from contacting the wall surface, and improve the heating effect on the air.

[0031] Reference Figure 5 In order to control the temperature rise of the graphene electric heating film 8, a temperature sensing element 10 is arranged in the wire 9. The temperature sensing element 10 is a thermistor. The temperature sensing element 10 is attached to the graphene electric heating film 8. When the surface temperature of the graphene electric heating film 8 is too high, the resistance value of the temperature sensing element 10 increases. At this time, the power of the graphene electric heating film 8 is reduced, so as to realize the temperature control effect. Meanwhile, in order to provide safety redundancy, the temperature sensing element 10 should be provided with at least two groups. An insulating flame-retardant layer 13 is arranged between the graphene electric heating film 8 and the decorative layer 14, so as to avoid fire induced by high temperature.

[0032] In order to improve the temperature resistance and fireproof ability, the insulating flame-retardant layer 13 adopts an epoxy resin plate. In order to improve the heat preservation ability, the heat preservation plate 4 adopts an aluminum foil heat preservation plate 4. In order to further save the cost, the insulating flame-retardant layer 13 adopts a glass fiber plate, and the heat preservation plate 4 adopts a glass fiber heat preservation plate 4.

[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
