Description

Technical Field

[0001] The utility model relates to the technical field of graphene, in particular to a graphene heating film. Background Technique

[0002] A heating film is a planar heating element composed of an electrical insulating material and a heating resistance material encapsulated therein. According to different heating materials, heating films can be divided into various types such as polymer, printing ink, carbon fiber, and metal wire. Although these heating films belong to the same type of electric heating element and have common or similar characteristics, due to the differences in the physical, chemical, electrochemical, electrothermal and other properties of different heating materials, the performance of each type of heating film also has its own characteristics. However, currently commonly used heating films all have certain potential safety hazards to varying degrees when in use.

[0003] As a new material, graphene has excellent optical, electrical and mechanical properties. When energized, carbon molecules in the graphene heating film will generate phonons, ions and electrons in the resistor. These carbon molecular groups rub and collide with each other, thereby generating heat energy. The heat energy is then evenly radiated in a planar manner through far-infrared rays with a controlled wavelength of 5 to 14 micrometers, and the total conversion rate of effective electrothermal energy is as high as over 99%. At the same time, the superconductivity of the graphene material ensures the stability of the heating performance. Compared with the conventional metal wire heating film, the graphene heating film is not only stable and safe in heating, but also the infrared rays emitted by it are known as the "life rays".

[0004] Nevertheless, the graphene heating films in the prior art still have some defects, such as uneven heating, inconvenient impedance monitoring, and relatively short service life. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model

[0005] To achieve the above object, the utility model is realized through the following technical solutions: A graphene heating film, comprising: a heating set film and a heat dissipation structure, and the heat dissipation structure is installed inside the heating set film;

[0006] The heat dissipation structure includes: a graphene heat conduction layer, a pair of electrodes, a plurality of graphene strips, a pair of toothed metal rods, a plurality of heat dissipation insulating tubes, and a silicone resin composite insulating heat conduction layer;

[0007] A pair of the electrodes are respectively installed on two sides of the graphene heat-conducting layer. The heating sleeve film is sleeved on the outside of the graphene heat-conducting layer. A plurality of the graphene strips are evenly installed on the graphene heat-conducting layer. A pair of toothed metal rods are evenly inserted inside the plurality of graphene strips. The silicone resin composite insulating and heat-conducting layer is installed on the inside of the heating sleeve film, and the silicone resin composite insulating and heat-conducting layer is sleeved on the moving toothed metal rods. A plurality of the heat-dissipating insulating tubes are evenly inserted into the plurality of graphene strips and a pair of toothed metal rods;

[0008] It should be noted that in the above, by leading the current to the inside of a pair of electrodes, heating the graphene heat-conducting layer through the pair of electrodes, and through the cooperation of a plurality of graphene strips, when the current passes through the graphene heat-conducting layer, due to the high conductivity of graphene, the current can flow rapidly and evenly heat the entire graphene heat-conducting layer in a short time. At the same time, by installing a plurality of graphene strips on the graphene heat-conducting layer, the plurality of graphene strips are heated by the current. Through a pair of toothed metal rods, the heat on the plurality of graphene strips and the graphene heat-conducting layer is led to the pair of toothed metal rods. The heat is dissipated to the inside of the heating sleeve film through the pair of toothed metal rods. The heat between the toothed metal rods, the plurality of graphene strips and the graphene heat-conducting layer is dissipated through a plurality of heat-dissipating insulating tubes. Through a plurality of heat-dissipating insulating tubes, the heat dissipation effect is heated. Through the cooperation of a plurality of graphene strips and the high heat conductivity of the graphene material itself, the temperature distribution on the surface of the heating film is ensured to be uniform, avoiding the problems of local overheating or uneven temperature. Through the design of a pair of toothed metal rods and a plurality of heat-dissipating insulating tubes, the heat on the graphene heat-conducting layer and the graphene strips is effectively dissipated, improving the heat dissipation efficiency of the entire system. This design helps to maintain the heating film within an appropriate working temperature range and extend its service life.

[0009] Preferably, a USB interface and an external power cord are respectively arranged on a pair of the electrodes.

[0010] Preferably, a plurality of the graphene strips are in a T shape.

[0011] Preferably, an insulating and flame-retardant layer is arranged on the inside of the heating sleeve film, and the insulating and flame-retardant layer is made of ethylene-propylene rubber material.
