[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] like Figure 1 and Figure 2 As shown, the high-temperature softened anti-bending PET film includes a thermal insulation coating 1, characterized in that: a PET structural layer 2 is provided above the thermal insulation coating 1, the PET structural layer 2 includes a plurality of regular hexagonal PET components 3 placed above the thermal insulation coating 1 and compactly distributed with each other, the interior of the PET component 3 is provided with a conical heat dissipation channel 4 running through the PET component 3, the PET component 3 includes a reverse element 8 connected to the heat dissipation coating 5, and a forward element 9 connected to the thermal insulation coating 1, and the heat dissipation channels 4 in the reverse element 8 and the forward element 9 are oriented in opposite directions.

[0023] In this embodiment, a PET structural layer 2 is formed by arranging a number of compactly distributed regular hexagonal PET components 3, and local components form an integrated film body. The conical heat dissipation channel 4 is used to dissipate heat from each PET component 3, thereby enhancing the overall heat resistance. At the same time, the regular hexagonal structure enhances the overall anti-bending ability, and the stability between each other is relatively strong. During the production, the PET film should first be produced by adopting a biaxial stretching technology to make the molecular chain highly oriented, thereby improving the strength and anti-bending performance, and then it should be divided into a number of PET components 3, and the components with the larger opening of the internal conical heat dissipation channel 4 facing the thermal insulation coating 1 and the heat dissipation coating 5 is connected to the heat insulation coating 1, which is the forward element 9, and the remaining components are connected to the heat insulation coating 1, which is the reverse element 8; when the heat insulation coating 1 is subjected to the heat source and the temperature continues to rise, the heat flows from the side with a larger opening to the side with a smaller opening. The forward element can increase the acceleration of the heat flow, thereby possibly increasing the relative speed between the fluid and the channel wall and improving the heat exchange efficiency. The reverse element has a reduced speed due to the expansion of the fluid, which may help to reduce the turbulence of the fluid flow and facilitate the heat dissipation of the heat dissipation coating 5. At the same time, when the components are heated and expanded, the side with a larger opening expands more than the other side, and the PET components 3 are heated and expanded and squeezed against each other from top to bottom, thereby increasing the integrity.

[0024] like Figure 3 and Figure 4 As shown, a heat dissipation coating 5 is provided above the PET structural layer 2, and a PC board 6 is provided on the side of the heat dissipation coating 5 close to the thermal insulation coating 1 and is sleeved on the outside of the PET structural layer 2, a silicone plate 7 embedded in the PC board 6 is provided on the outer circle of the PC board 6, and a nano-silicon layer 10 is provided between the PET components 3.

[0025] In this embodiment, the PET component 3 is divided into several layers by the nano silicon layer 10, and its overall heat resistance is increased. The multi-layer design optimizes the overall material performance by combining the advantages of different materials. Each layer can be customized to provide the required specific functions, such as wear resistance, corrosion resistance or thermal stability. At the same time, the multi-layer structure can improve the overall durability and life of the material by dispersing stress, resisting crack propagation and improving impact absorption. Each layer can have complementary characteristics to improve the overall durability and reliability; the silicone plate 7 can better assist the film in resisting bending by virtue of its own elastic reset function.

[0026] When in use, the PET film is first processed using a biaxial stretching technique to orient the molecular chains to a high degree, so as to improve the strength and bending resistance of the material; the processed PET film is divided into a number of regular hexagonal PET components 3, and a conical heat dissipation channel 4 is designed inside each component; the component with a conical heat dissipation channel 4 with a larger opening facing the thermal insulation coating 1 is regarded as a forward element 9, which is connected to the heat dissipation coating 5; the rest is regarded as a reverse element 8, which is connected to the thermal insulation coating 1. In this way, a PET structural layer 2 with forward and reverse elements is formed between the thermal insulation coating 1 and the heat dissipation coating 5; finally, the heat dissipation coating 5 is covered on the top of the PET structural layer 2, and a PC board 6 and a silicone plate 7 are arranged on the outside for protection and reinforcement. At the same time, a nano silicon layer 10 is arranged between the PET components 3 to enhance the overall thermal performance and stability. Through the design of the conical heat dissipation channel 4, the rapid dispersion of heat is effectively achieved, and the heat resistance of the overall material is improved; the regular hexagonal PET component 3 enhances the overall stability and anti-bending ability of the material; the design of the forward element 9 and the reverse element 8 helps to improve the heat exchange efficiency, properly control the heat flow speed and turbulence, and improve the heat dissipation performance; the multi-layer design combines the advantages of different materials, and improves the overall durability and life of the material through mechanisms such as dispersing stress and resisting crack propagation; the material of each layer can be customized according to needs, providing specific functions such as wear resistance, corrosion resistance or thermal stability, and enhancing the application flexibility and practical value of the material. Overall, this high-temperature softened anti-bending PET film provides superior thermal management and physical properties through innovative design of structure and materials, and is suitable for applications requiring high heat resistance and stability.

[0027] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
