Description

Technical Field

[0001] This utility model relates to the field of decoration and building materials technology, and in particular to a graphene floor heating electric heating component with plastic layer encapsulation. Background Technology

[0002] As residents' living standards continue to improve, they have higher requirements for the comfort of their living environment. Installing underfloor heating can improve the comfort of the living environment during winter.

[0003] Due to its extremely high conductivity, graphene can rapidly convert electrical energy into heat when energized. Furthermore, graphene has low resistivity, resulting in more uniform heating than traditional metal wires. Therefore, graphene heating components have gained popularity among manufacturers. Additionally, the ultra-thin nature of graphene is an advantage in achieving product lightweighting. Utility model patent CN212299151U discloses a far-infrared cloud-based floor heating system. Its principle involves energizing a graphene heating film, and then, through a reflective film beneath the film and surrounding insulation, directing the heat generated towards the floor to meet the requirements of floor heating.

[0004] This patent also has shortcomings: First, the integration of the graphene heating element is not compact enough, and the lightweight nature of the patented product needs further improvement. Second, the reliability of the contact between the graphene heating film and the copper strip is insufficient, resulting in high resistance at local contact points. This can cause the graphene heating film to overheat and burn out under the thermal effect of the resistance, leading to the copper strip detaching from the graphene heating film and causing the graphene heating film to fail. Third, this product cannot be adapted to the material selection requirements based on site space. Utility Model Content

[0005] This utility model provides a plastic-encapsulated graphene electric heating component. The purpose of developing this product is: first, to further improve the integration of the graphene electric heating component, thereby improving its lightweight nature; second, to reduce the occurrence of burn-out failure of the electric heating component during use, thereby improving the product's service life; and third, this product can adapt to different installation environments in the field.

[0006] The following describes the technical solution. Before proceeding, the following material abbreviations in the industry are explained: PET is polyethylene terephthalate; PVC is polyvinyl chloride; PE is polyethylene.

[0007] A plastic-encapsulated graphene electric heating component includes an upper plastic layer 1 and a lower plastic layer 2. A graphene heating element layer 3 is disposed between the upper plastic layer 1 and the lower plastic layer 2. The graphene heating element layer 3 includes an upper PET layer 5, a lower PET layer 6, a reflective film 4, a graphene paste layer 7, silver bars 8, and copper bars 9. The reflective film 4, graphene paste layer 7, silver bars 8, and copper bars 9 are disposed between the upper PET layer 5 and the lower PET layer 6. The graphene paste layer 7 is printed on the lower PET layer 6. The silver bars 8 include a first silver bar 81 and a second silver bar 82. The copper bars 9 include a first copper bar 91 and a second copper bar 92. The first silver bar 81 and the second silver bar 82 are respectively printed on the left and right ends of the graphene paste layer 7.

[0008] Preferably, the first silver bar 81 is connected to the first copper bar 91, and the second silver bar 82 is connected to the second copper bar 92.

[0009] Preferably, the reflective film 4 is disposed in the middle of the upper PET layer 5.

[0010] Preferably, the graphene paste layer 7 has several shear lines 10 arranged in the transverse direction.

[0011] Preferably, the first copper bar 91 and the second copper bar 92 are connected to the wire harness 11 via wires.

[0012] Preferably, the surface of the upper plastic layer 1 is frosted and the surface of the lower plastic layer 2 is smooth.

[0013] Preferably, the upper plastic layer 1 and the lower plastic layer 2 are made of PVC or PE.

[0014] The beneficial effects of this utility model are as follows: First, this product achieves an ultra-thin structure by using graphene material printing and feeding, further improving the product's lightweight nature while increasing manufacturing efficiency. Second, the high conductivity of silver reduces the transition resistance of the electrodes on both sides of the graphene paste layer 7, lowering the resistive heating effect that should be avoided at the electrode positions, preventing melting at the electrode connection points, and improving the product's service life. Third, the shearing line divides the graphene paste layer into several segments, forming a parallel circuit between each segment. If one segment fails due to an open circuit, the remaining segments can still continue to work normally. Furthermore, the shearing line can cut products to matching sizes according to on-site requirements, adapting to diverse installation environments. Attached Figure Description

[0019] The present invention will be further described in conjunction with the following specific embodiments.

[0020] Appendix Figure 1 To be continued Figure 4 The markings in the diagram are as follows: Upper plastic layer 1, Lower plastic layer 2, Graphene heating element layer 3, Reflective film 4, Upper PET layer 5, Lower PET layer 6, Graphene paste layer 7, Silver bar 8, First silver bar 81, Second silver bar 82, Copper bar 9, First copper bar 91, Second copper bar 92, Cutting line 10, Wire harness 11.

[0021] A plastic-encapsulated graphene electrothermal component includes an upper plastic layer 1 and a lower plastic layer 2. A graphene heating element layer 3 is disposed between the upper plastic layer 1 and the lower plastic layer 2. The graphene heating element layer 3 includes an upper PET layer 5, a lower PET layer 6, a reflective film 4, a graphene paste layer 7, a silver bar 8, and a copper bar 9. The reflective film 4, graphene paste layer 7, silver bar 8, and copper bar 9 are disposed between the upper PET layer 5 and the lower PET layer 6. The graphene paste layer 7 is printed on the lower PET layer 6. The graphene material printing method is used to achieve the ultra-thin structure of the product, further improving the product's lightweight nature. The silver bar 8 includes a first silver bar 81 and a second silver bar 82. The copper bar 9 includes a first copper bar 91 and a second copper bar 92. The first silver bar 81 and the second silver bar 82 are respectively printed on the left and right ends of the graphene paste layer 7. The high conductivity of silver reduces the resistance of the electrodes on both sides of the graphene paste layer 7, reduces the resistive heating effect that should be avoided at the electrode positions, and improves the product's service life.

[0022] The first silver bar 81 is connected to the first copper bar 91, and the second silver bar 82 is connected to the second copper bar 92. Silver is a traditional precious metal and is expensive. The functional requirements can be met by using less silver material at the electrode position.

[0023] The reflective film 4 is disposed in the middle of the upper PET layer 5. The reflective film 4 reflects the thermal radiation generated by the graphene heating element layer 3, so that heat is transferred in the direction that needs to be transferred.

[0024] The graphene paste layer 7 has several shear lines 10 arranged laterally. These shear lines divide the graphene paste layer into several segments, forming parallel circuits between them. If one segment is broken, it will not generate heat, but the other segments will continue to operate normally. Furthermore, the shear lines can be cut to the appropriate dimensions according to site requirements, adapting to different installation conditions. Since the graphene heating element is encapsulated between the upper plastic layer 1 and the lower plastic layer 2, there are corresponding markings on the outer surface of the plastic layers. Cutting the product to the required size along the marked direction will not damage the inner core.

[0025] The first copper strip 91 and the second copper strip 92 are connected to the wire harness 11 by wires, and the first copper strip 91 and the second copper strip 92 are connected to the power supply electrode, so that a heating circuit is formed between the graphene heating element layer 3 and the power supply.

[0026] The upper plastic layer 1 has a frosted surface, and the lower plastic layer 2 has a smooth surface. The frosted surface contacts the concrete floor layer, and the smooth surface faces upwards and contacts the floor layer.

[0027] The upper plastic layer 1 and the lower plastic layer 2 are made of PVC or PE.

[0028] Finally, it should be noted that this embodiment is a preferred example of the present utility model and is not intended to limit the present utility model.
