Description

Technical Field

[0001] This utility model relates to the field of graphene heat dissipation film technology, specifically a multilayer graphene heat dissipation film. Background Technology

[0002] Graphene heat dissipation film is a heat dissipation product made primarily of graphene. It is mainly used to efficiently dissipate heat from electronic products and ensure their stable operation.

[0003] Most currently used graphene heat dissipation films cannot prevent leakage and short circuits, and their heat resistance is poor. During use, electronic devices have densely packed internal circuits. If short circuits and leakage cannot be prevented, the heat dissipation film may come into contact with lines or components at different potentials, potentially causing abnormal current conduction, short circuits, circuit failures, damage to electronic components, and even fires. Furthermore, when a person comes into contact with the graphene heat dissipation film, if the device has a leakage problem, the film will become charged, easily causing electric shock accidents. This makes the graphene heat dissipation film quite unsafe. Graphene heat dissipation films are not heat-resistant, which can lead to accelerated deterioration of their internal structure during prolonged use at high temperatures, resulting in decreased performance and reduced heat dissipation efficiency. This results in a shorter lifespan for the graphene heat dissipation film. Furthermore, the lack of external protection for the graphene heat dissipation film makes it highly susceptible to friction, collisions, or pressure during daily use, transportation, or installation, causing damage and rendering it unusable. This also results in lower strength for the graphene heat dissipation film. Utility Model Content

[0004] The purpose of this invention is to provide a multilayer graphene heat dissipation film to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multilayer graphene heat dissipation film, comprising a heat dissipation film body, an insulating and heat-resistant component disposed on the top of the heat dissipation film body, the insulating and heat-resistant component comprising a first insulating adhesive coating, the first insulating adhesive coating being fixedly connected to the top of the heat dissipation film body, a second insulating adhesive coating being fixedly connected to the bottom of the heat dissipation film body, a first polyester resin layer being fixedly connected to the top of the first insulating adhesive coating, and a second polyester resin layer being fixedly connected to the bottom of the second insulating adhesive coating.

[0006] As a preferred technical solution, the shape and size of the heat dissipation film body match the shape and size of the first insulating adhesive coating, and the vertical center line of the first heat dissipation film body coincides with the vertical center line of the first insulating adhesive coating.

[0007] As a preferred technical solution, the shape and size of the first insulating adhesive coating match the shape and size of the first polyester resin layer, and the vertical center line of the first insulating adhesive coating coincides with the vertical center line of the first polyester resin layer.

[0008] As a preferred technical solution, the first insulating adhesive coating and the second insulating adhesive coating are symmetrically arranged with the parallel center line of the heat dissipation film body as the axis of symmetry.

[0009] As a preferred technical solution, a protective component is provided on the top of the first polyester resin layer, the protective component including a first aluminum nitride layer, and the first aluminum nitride layer is fixedly connected to the top of the first polyester resin layer.

[0010] As a preferred technical solution, a second aluminum nitride layer is fixedly connected to the bottom of the second polyester resin layer, and the shape and size of the second aluminum nitride layer match the shape and size of the second polyester resin layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the inclusion of insulating and heat-resistant components, can prevent leakage and short circuits in the graphene heat dissipation film and enhance its heat resistance. During use, the first and second insulating adhesive coatings provide insulation and shock absorption for the heat dissipation film body, while the first and second polyester resin layers improve its heat resistance. This prevents short circuits and leakage caused by the inability to prevent short circuits from occurring, which could lead to the heat dissipation film contacting circuits or components at different potentials, causing abnormal current conduction, short circuits, circuit malfunctions, and damage to electronic components. It could even cause a fire, and if the equipment has a leakage, the graphene heat dissipation film will become electrified when a person comes into contact with it, which could easily lead to an electric shock. In addition to ensuring the insulation of the graphene heat dissipation film, the first and second insulating adhesive coatings can also play a role in shock absorption and cushioning, making the graphene heat dissipation film safe. It also avoids the situation where the internal structure of the graphene heat dissipation film deteriorates rapidly due to its lack of heat resistance, resulting in a decrease in performance and a decrease in heat dissipation effect after long-term use at high temperatures, thus ensuring the service life of the graphene heat dissipation film.

[0013] 2. This utility model, through the setting of protective components, can achieve the function of protecting the exterior of the graphene heat dissipation film. During use, due to the high strength, high hardness, high thermal conductivity, and good wear resistance of the aluminum nitride layer, the first aluminum nitride layer and the second aluminum nitride layer protect the graphene heat dissipation film. This not only provides protection for the graphene heat dissipation film, but also improves the heat dissipation efficiency of the graphene heat dissipation film. It can avoid the situation where the graphene heat dissipation film is easily damaged by friction, collision, or squeezing during daily use, transportation, or installation due to the lack of external protection, thus ensuring the strength and heat dissipation efficiency of the graphene heat dissipation film.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides the following technical solution, including a heat dissipation film body 1, an insulating heat-resistant component 2 disposed on the top of the heat dissipation film body 1, and a protective component 3 disposed on the top of the first polyester resin layer 203.

[0020] Specifically: when using the heat dissipation film body 1, the insulating heat-resistant component 2 is provided to prevent short circuits or leakage of electronic equipment. When the temperature of electronic equipment is high during heat dissipation, the insulating heat-resistant component 2 is provided to improve the heat resistance of the heat dissipation film body 1. When the heat dissipation film body 1 is subjected to friction, collision or pressure, the protective component 3 is provided to protect the heat dissipation film body 1 and prevent it from being damaged by friction, collision or pressure, thereby completing the work.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, an insulating and heat-resistant component 2 is provided on the top of the heat dissipation film body 1. The insulating and heat-resistant component 2 includes a first insulating adhesive coating 201. The first insulating adhesive coating 201 is fixedly connected to the top of the heat dissipation film body 1, and a second insulating adhesive coating 202 is fixedly connected to the bottom of the heat dissipation film body 1. A first polyester resin layer 203 is fixedly connected to the top of the first insulating adhesive coating 201, and a second polyester resin layer 204 is fixedly connected to the bottom of the second insulating adhesive coating 202. The shape and size of the heat dissipation film body 1 match the shape and size of the first insulating adhesive coating 201, and the vertical center line of the first heat dissipation film body 1 coincides with the vertical center line of the first insulating adhesive coating 201. The shape and size of the first insulating adhesive coating 201 match the shape and size of the first polyester resin layer 203, and the vertical center line of the first insulating adhesive coating 201 coincides with the vertical center line of the first polyester resin layer 203. The first insulating adhesive coating 201 and the second insulating adhesive coating 202 are symmetrically arranged about the parallel center line of the heat dissipation film body 1 as the axis of symmetry.

[0022] Specifically, when using the heat dissipation film body 1, the first insulating adhesive coating 201 and the second insulating adhesive coating 202 are used to prevent short circuits in electronic devices and leakage current in the heat dissipation film body 1, which could lead to personal injury. At the same time, if there is external vibration, the first insulating adhesive coating 201 and the second insulating adhesive coating 202 will dampen and buffer the external force, thereby completing the insulation and buffering work. When the temperature of the electronic device is high during heat dissipation, the first polyester resin layer 203 and the second polyester resin layer 204 are used to give the heat dissipation film body 1 high heat resistance, thereby ensuring the heat dissipation performance and service life of the heat dissipation film body 1, thus completing the heat resistance work.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a protective component 3 is provided on the top of the first polyester resin layer 203. The protective component 3 includes a first aluminum nitride layer 301. The first aluminum nitride layer 301 is fixedly connected to the top of the first polyester resin layer 203. A second aluminum nitride layer 302 is fixedly connected to the bottom of the second polyester resin layer 204. The shape and size of the second aluminum nitride layer 302 match the shape and size of the second polyester resin layer 204.

[0024] Specifically, when the heat dissipation film body 1 is subjected to friction, collision or compression, the first aluminum nitride layer 301 and the second aluminum nitride layer 302 are provided to protect the heat dissipation film body 1, preventing it from being damaged by friction, collision or compression. Furthermore, the first aluminum nitride layer 301 and the second aluminum nitride layer 302 are used to improve the heat dissipation efficiency of the heat dissipation film body 1, thereby completing the protection work.

[0025] The working principle of this utility model is as follows: When using the heat dissipation film body 1, the first insulating adhesive coating 201 and the second insulating adhesive coating 202 prevent short circuits in electronic devices and leakage current in the heat dissipation film body 1, thus preventing injuries to personnel. At the same time, if there is external vibration, the first insulating adhesive coating 201 and the second insulating adhesive coating 202 will dampen and buffer the external force, thereby completing the insulation and buffering work. When the temperature of the electronic device is high during heat dissipation, the first polyester resin layer 203 and the second polyester resin layer 204 give the heat dissipation film body 1 high heat resistance, thereby ensuring the heat dissipation performance and service life of the heat dissipation film body 1, thus completing the heat resistance work. When the heat dissipation film body 1 is subjected to friction, collision or pressure, the first aluminum nitride layer 301 and the second aluminum nitride layer 302 protect the heat dissipation film body 1, preventing the heat dissipation film body 1 from being damaged by friction, collision or pressure. Furthermore, the first aluminum nitride layer 301 and the second aluminum nitride layer 302 make the heat dissipation efficiency of the heat dissipation film body 1 higher, thereby completing the protection work.
