[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] See Figure 1-3A graphite auxiliary heating module includes a shell 1 and a sealing plate 2, and also includes at least two groups of heating components 3, and the two groups of heating components 3 are bonded to each other, the heating components 3 are arranged in the cavity of the shell 1, and are sealed and fixed by the sealing plate 2; the heating components 3 include a graphene electric heating film 31, a PE film 32 and a reflecting plate 33, the PE film 32 and the reflecting plate 33 are respectively located on the upper and lower sides of the graphene electric heating film 31, and the reflecting plates 33 of the two groups of heating components 3 are bonded to each other, and the PE film 32 is respectively arranged corresponding to the shell 1 and the sealing plate 2. Specifically, the utility model adopts the graphene electric heating film 31 as the core component, organically unifies several materials, and forms an integrated auxiliary heating module; the reflecting plates are adhered with high-temperature resistant double-sided tape, which can reflect the heat of the graphene electric heating film to the inner surface of the sheet metal shell, accelerate heat transfer, and reduce heat accumulation inside the cavity; the PE film 32 effectively avoids the loss of the shell during the installation process of the shell, and punctures the graphene electric heating film during the assembly process, and also plays an insulating and protective role.

[0020] In this embodiment, high-temperature resistant double-sided tape is used to stick the heating components 3, the heating components 3 and the shell 1 and the sealing plate 2 together; high-temperature resistant double-sided tape is also used to stick the graphene electric heating film 31, the PE film 32 and the reflective plate 33 together. The PE insulating film is stuck to the specified position of the shell with high-temperature resistant double-sided tape. The purpose is to effectively avoid the damage caused by the shell during the installation process, which may puncture the graphene electric heating film during the assembly process, and at the same time play an insulating and protective role; the graphene electric heating film is stuck to the PE insulating film with high-temperature resistant double-sided tape, so that the graphene electric heating film and the stainless steel installation shell are infinitely close, which facilitates the heat conduction of the graphene electric heating film.

[0021] In this embodiment, sealant is applied to the outer surfaces of the housing 1 and the sealing plate 2. The sealant ensures a good sealing effect, preventing water, steam, etc. from invading the interior of the stainless steel mounting housing.

[0022] In this embodiment, two flange surfaces 4 are provided on the sealing plate 1. The power line of the graphene electric heating film 31 is provided through the flange surface 4. A waterproof ring 5 is provided on the power line and embedded in the flange surface 4. The waterproof ring 5 is used in conjunction with the flange surface 4 to improve the sealing performance and prevent water vapor from entering the interior of the stainless steel mounting housing through the flange surface 4.

[0023] In this embodiment, the graphene heating film 31 includes a graphene heating film core 311, which is surrounded by a PE waterproof sleeve 312. A temperature switch 313 is connected between the positive and negative electrodes of the graphene heating film core 311 by a wire, which is then connected to a power cord. The temperature switch 313 can cut off the power supply when the temperature reaches a set value and turn it on again when the temperature falls below the set value. Therefore, temperature switches of different specifications can be installed to control the maximum temperature limit, indirectly adjusting the temperature of the entire module and making it suitable for different occasions. The PE waterproof sleeve 312 protects the graphene heating film 31.

[0024] In summary, the present invention has the following advantages:

[0025] 1. Module integration

[0026] The utility model uses graphene electric heating film as the core component and organically unifies several materials to form an integrated auxiliary heating module; the module is easy to install in various application scenarios and is also very convenient to transport.

[0027] 2. High safety performance

[0028] The utility model adopts a stainless steel sheet metal shell to place the graphene electric heating film inside, and has a PE insulating film for secondary protection. The electric heating film is no longer scratched or crushed, thereby avoiding the risk of leakage and greatly improving the safety performance of the electric heating film.

[0029] 3. High waterproof performance

[0030] The graphene-assisted heating module of the utility model adopts an integral design, and the graphene electric heating film is placed inside a fully enclosed stainless steel shell. Before the shell is closed, it is sealed with a high-density waterproof sealant and riveted on all sides. At the same time, the outlet end of the electric heating film adopts an IP67 silicone waterproof ring. Actual test results show that it can ensure the long-term operation of the module at a humidity of less than 95%, showing high waterproof performance.

[0031] 4. High thermal conductivity:

[0032] Graphene's thermal conductivity is as high as 3000W (mk), five times that of copper. Therefore, it can convert and transport heat energy at the fastest speed, achieving a thermal conductivity efficiency that exceeds any other heating method. The module design can achieve low power consumption and high output functions, intermittently supplementing the ambient temperature or equipment to maintain the temperature within a prescribed range, indirectly reducing overall energy consumption.

[0033] 5. Adjustable temperature:

[0034] The temperature switch installed in the graphene heating film envelope can cut off the power supply when the temperature reaches the set value, and turn it on again when the temperature drops below the set value. Therefore, different specifications of temperature switches can be installed to control the upper limit of the temperature, indirectly adjusting the temperature of the entire module, making it suitable for different occasions.

[0035] 6. Benefits:

[0036] This utility model not only improves the safety performance of graphene heating film, but also diversifies the applications of traditional graphene heating film. Its adjustable size and power allow it to be used in a wide variety of applications, including building heating, process heating, medical assistance, ecological farming, and low-temperature drying. This has positively impacted the overall sales of graphene heating film, increasing its sales.

[0037] Furthermore, since its invention, this module has been extensively tested on low-temperature, high-humidity thawing equipment. During the thawing process, the module works with a steam generator to intermittently replenish the ambient temperature of the thawing chamber, maintaining it within a predefined range of positive and negative values. Furthermore, a year-long analysis of thawing data revealed that thawing equipment equipped with the graphene-assisted heating module saves approximately 15% of electricity compared to traditional low-temperature, high-humidity thawing equipment. This not only increases the added value of thawing equipment but also aligns well with current national energy conservation and emission reduction policies, making it highly worthy of promotion.

[0038] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
