Description

Technical Field

[0001] This utility model relates to the field of underfloor heating technology, specifically to a graphene-heated underfloor heating panel. Background Technology

[0002] Graphene-heated underfloor heating panels are a new type of underfloor heating device. In principle, it utilizes the excellent electrical and thermal conductivity of graphene to generate heat. When electricity is applied to the graphene, the internal electron movement accelerates, generating a large amount of heat energy, which is then evenly transferred out. Structurally, it typically consists of a graphene heating layer, an insulation layer, and a waterproof layer. The heating layer is the core component, enabling rapid and efficient heating; the insulation layer ensures safety and prevents electrical leakage; and the waterproof layer prevents moisture from damaging the heating system.

[0003] Current graphene-heated underfloor heating panels have some shortcomings that need improvement. They lack temperature monitoring capabilities, failing to accurately monitor and regulate indoor temperature in real time, which inconveniences users and makes it difficult to precisely meet diverse heating needs. Furthermore, the panels have poor insulation performance; during use, a large amount of heat easily penetrates directly downwards, failing to be effectively retained and circulated within the indoor space, resulting in significant heat loss. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a graphene-heated floor heating panel that can monitor the temperature of the floor heating panel and has the ability to prevent heat from penetrating downwards.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a graphene-heated underfloor heating panel, comprising:

[0006] Graphene thermal conductive layer is a continuous sheet structure made up of one or more layers of graphene sheets.

[0007] An insulating protective layer, in sheet form, is tightly wrapped around the graphene thermally conductive layer;

[0008] A metal conductive component includes a metal busbar and a metal electrode. The metal busbar and the graphene thermally conductive layer are electrically connected through a connection point. One end of the metal electrode is fixedly connected to the metal busbar and is electrically conductive.

[0009] The temperature monitor has its probe fixed inside or on the surface of the graphene thermal conductive layer, and the temperature monitor is connected to the outside through wires to form a signal transmission connection.

[0010] The encapsulation shell is wrapped around the graphene thermal conductive layer and the insulating protective layer. The end of the metal electrode away from the metal busbar and the other end of the wire connected to the temperature monitor both extend to the outside through the encapsulation shell. The bottom of the encapsulation shell has a heat-insulating and reflective layer, which is composed of a metal foil layer and a heat-insulating material layer. The metal foil layer is located on the side close to the graphene thermal conductive layer, and the heat-insulating material layer is located below the metal foil layer.

[0011] Furthermore, the graphene sheets that make up the graphene thermal conductive layer have connecting structures that allow them to form a whole, and the whole is planar and flexible. The connecting structure of the graphene sheets in the graphene thermal conductive layer is edge overlap connection or connection through intermediate connectors.

[0012] Furthermore, the insulating protective layer is a continuous, homogeneous, and uniformly thick polymer material layer, which is tightly bonded to the contact surface of the graphene thermal conductive layer, and its edge is sealed after wrapping the graphene thermal conductive layer.

[0013] Furthermore, the metal busbar is a long strip-shaped metal component, and the connection between the metal busbar and the graphene thermal conductive layer is a welding point connection. The metal electrode is a sheet-shaped metal component, and the connection between the metal electrode and the metal busbar is an integrally formed structure.

[0014] Furthermore, the probe of the temperature monitor has a block or rod-shaped structure, and its fixing structure with the graphene thermal conductive layer is an embedded fixing or an adhesive fixing.

[0015] The heat-insulating reflective metal foil layer and the heat-insulating material layer of the encapsulation shell are bonded together, and the heat-insulating material layer has anti-slip texture on the underside.

[0016] Compared with existing technologies, the advantages of this invention are as follows: This graphene-heated underfloor heating panel is equipped with a temperature monitor, and its probe is fixed inside or on the surface of the graphene heat-conducting layer through embedding or adhesive methods. This secure fixing method allows the probe to accurately and stably acquire the real-time temperature of the heat-conducting layer, ensuring the accuracy of the monitoring data. Simultaneously, it establishes a signal transmission connection with the outside via wires, enabling the measured temperature data to be transmitted to an external control terminal in a timely manner. This allows for precise control of the heating status of the underfloor heating panel, ensuring a constant and comfortable indoor temperature. This not only meets heating needs but also avoids energy waste, greatly enhancing the user experience.

[0017] A heat-reflective layer, composed of a metal foil layer and a heat-insulating material layer, is located at the bottom of the outer casing. The metal foil layer, with its excellent heat-reflective properties, reflects the heat generated by the graphene heat-conducting layer back, reducing downward heat transfer. The heat-insulating material layer acts as a barrier, effectively preventing further heat loss. This ensures the heat-reflective layer continues to function effectively, fully utilizing its heat-prevention function to improve overall heating efficiency. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Combined with appendix Figure 4 A graphene-heated underfloor heating panel includes: a graphene heat-conducting layer 1, which is a continuous sheet structure composed of single or multiple layers of graphene sheets. The graphene sheets constituting the graphene heat-conducting layer 1 have connecting structures that make them form a whole, and the whole is planar and flexible. The connecting structure of the graphene sheets in the graphene heat-conducting layer 1 is edge overlapping connection or connection through intermediate connectors. The specific connecting structure makes the graphene sheets form a whole, planar and flexible, which is convenient for laying and installation, and can ensure stable power supply, so that the graphene heat-conducting layer 1 can achieve uniform and sufficient heating.

[0026] Combined with appendix Figure 4 The insulating protective layer 2 is a sheet tightly wrapped around the graphene thermal conductive layer 1. The insulating protective layer 2 is a continuous, homogeneous, and uniformly thick polymer material layer. Its contact surface with the graphene thermal conductive layer 1 is tightly adhered, and its edges are sealed after wrapping the graphene thermal conductive layer 1. This not only effectively provides insulation and protection but also ensures the stability of the overall structure and prevents external factors from affecting the internal components.

[0027] Combined with appendix Figure 4 Appendix Figure 5The metal conductive component includes a metal busbar 4 and a metal electrode 5. The metal busbar 4 is electrically connected to the graphene thermal conductive layer 1 through a connection point. One end of the metal electrode 5 is fixedly connected to the metal busbar 4 and is electrically conductive. The metal busbar 4 is a long strip-shaped metal component. The connection point between the metal busbar 4 and the graphene thermal conductive layer 1 is a welded connection. The metal electrode 5 is a sheet-shaped metal component. The connection point between the metal electrode 5 and the metal busbar 4 is an integrally formed structure. The welded connection of the metal busbar 4 ensures reliable electrical connection with the graphene thermal conductive layer. The integral forming of the metal electrode and the busbar enhances the stability of the connection point, facilitates stable current transmission, and ensures normal heating function.

[0028] Combined with appendix Figure 4 Appendix Figure 5 The temperature monitor 6 has its probe fixed inside or on the surface of the graphene heat-conducting layer 1. The temperature monitor 6 is connected to the outside via the wire 3 to form a signal transmission connection. The probe of the temperature monitor 6 has a block or rod-shaped structure. Its fixing structure with the graphene heat-conducting layer 1 is an embedded fixing or adhesive fixing, which can firmly fix it on the graphene heat-conducting layer 1, accurately monitor the temperature, and thus accurately feed back information, making it easy to control the heating status of the floor heating board.

[0029] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The encapsulation shell 7 is wrapped around the graphene thermally conductive layer 1 and the insulating protective layer 2. The end of the metal electrode 5 away from the metal busbar 4 and the other end of the wire 3 connected to the temperature monitor 6 both extend to the outside through the encapsulation shell 7. The bottom of the encapsulation shell 7 has a heat-insulating and reflective layer 8, which consists of a metal foil layer and a heat-insulating material layer. The metal foil layer is located on the side closer to the graphene thermally conductive layer 1, and the heat-insulating material layer is located below the metal foil layer. The metal foil layer and the heat-insulating material layer of the heat-insulating and reflective layer 8 of the encapsulation shell 7 are bonded and fixed together. The heat-insulating material layer has anti-slip textures on the bottom. The bonding and fixing ensures a tight structure, and the anti-slip textures ensure that the underfloor heating panel will not slip after installation, which improves the heat insulation effect and increases the safety and stability during use.

[0030] The specific implementation of this utility model is as follows: When using this graphene-heated floor heating panel, first, place the side of the encapsulated shell 7 with the heat-insulating reflective layer 8 facing down. Based on the room's floor dimensions and installation plan, place the floor heating panel stably on the ground. Utilize the anti-slip texture beneath the heat-insulating material layer of the heat-insulating reflective layer 8 to ensure the installed floor heating panel does not slide freely. Next, connect the end of the metal electrode 5 furthest from the metal busbar 4 to an external power source, allowing current to be conducted through the metal electrode 5 to the integrally formed metal busbar 4. Then, the current flows into the graphene heat-conducting layer 1 via the welding point of the metal busbar 4, thus energizing and heating it. During use, the temperature monitor 6 monitors the temperature of the heat-conducting layer in real time through a probe and transmits the temperature signal to a connected external temperature control system or other related equipment via the wire 3. If the temperature exceeds or falls below the set range, the power supply can be adjusted accordingly to ensure a suitable indoor temperature. The insulating protective layer 2 always tightly wraps around the graphene heat-conducting layer 1, serving as insulation and protection as well as stabilizing the overall structure, ensuring the safe and stable operation of the underfloor heating panel. During the use of the underfloor heating panel, the heat-reflective layer 8 can reflect the heat generated by the graphene heat-conducting layer back, reducing downward transmission and penetration, thereby reducing energy loss.
