Description

Technical Field

[0001] This utility model relates to the field of metal composite material technology, specifically to a heat dissipation sandwich structure metal-based composite film. Background Technology

[0002] Metal composite materials refer to composite materials prepared with metals or alloys as the matrix material, with the second item being the reinforcing material. Existing metal composite materials have characteristics such as high specific strength, good electrical and thermal conductivity, low coefficient of thermal expansion, dimensional stability, good wear resistance, good heat resistance, and good airtightness. The reinforcing material in metal composite materials determines the properties of the composite material itself. At the same time, the characteristics of the reinforcing material also require good chemical stability and good wettability to ensure chemical compatibility and uniform distribution during composite formation. The choice of metal matrix determines the performance of metal composite materials. The selected metal matrix should primarily possess the properties of reinforcing fibers, while the matrix itself needs to have good compatibility and plasticity. Different metal matrices contain different alloying elements, and the degree of reaction between alloying elements and reinforcing materials varies, resulting in different reaction products, i.e., metal composite materials. One of the representative materials in the field of metal composite materials is metal matrix composite membrane. With the continuous improvement and innovation of people's technological level, metal matrix composite membrane has been widely used in various industries.

[0003] Most existing metal-based composite films improve overall airtightness and conductivity, but often neglect the heat dissipation performance of the surface after the metal-based composite film is attached to the equipment. This may lead to an increase in the surface temperature of the equipment, resulting in thermal breakdown of the composite film or damage to the equipment's components. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation sandwich structure metal-based composite film to solve the problem mentioned in the background art that existing metal substrates do not have good heat dissipation properties.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation sandwich structure metal-based composite film, comprising a surface layer and a bottom layer, wherein the outer surface of the surface layer has pores and a scale strip.

[0006] A heat dissipation mechanism is connected to the inner wall of the surface layer, and this mechanism enables the metal-based composite film to have good heat dissipation performance.

[0007] The outer surface of the heat dissipation mechanism is connected to the bottom layer, and the outer surface of the bottom layer is provided with a second air hole. The outer surface of the bottom layer is connected to the adhesive layer. A connecting mechanism is provided on one side of the surface layer and the bottom layer, and the connecting mechanism allows the metal-based composite film to be easily cut as needed.

[0008] Preferably, the heat dissipation mechanism comprises a heat dissipation layer, a first limiting hole, and a second limiting hole. The upper surface of the heat dissipation layer is attached to the lower surface of the surface layer. The outer surface of the first limiting hole is connected to the inner wall of the first air hole. One end of the first limiting hole is fixedly installed on the upper surface of the heat dissipation layer and communicates with the inner wall of the heat dissipation layer. The lower surface of the heat dissipation layer is attached to the upper surface of the bottom layer. The outer surface of the second limiting hole is connected to the inner wall of the second air hole. One end of the second limiting hole is fixedly installed on the lower surface of the heat dissipation layer and communicates with the inner wall of the heat dissipation layer.

[0009] The above technical solution demonstrates that the metal-based composite film has excellent heat dissipation performance.

[0010] Preferably, the connecting mechanism consists of a connecting strip, an opening, and a retaining sticker, wherein the connecting strip is connected to one side of the surface layer and the bottom layer, the upper surface of the connecting strip is provided with a scale strip, the upper surface of the connecting strip is connected with a retaining sticker, and the upper surface of the connecting strip has an opening.

[0011] The above technical solution demonstrates that the composite film is easy for workers to tear during cutting.

[0012] Preferably, the outer surface of the limiting hole one and the inner wall of the air hole one are engaged and connected.

[0013] By adopting the above technical solution, it is ensured that the heat inside the heat dissipation layer can be released from the limiting hole to the outside of the surface, thereby achieving the function of heat dissipation.

[0014] Preferably, the outer surface of the second limiting hole and the inner wall of the second air hole are engaged and connected.

[0015] By adopting the above technical solution, the heat generated on the surface of the equipment can be introduced into the heat dissipation layer through the second limiting hole and then discharged.

[0016] Preferably, the bottom surface of the stabilizing adhesive is attached to the upper surface of the opening.

[0017] Using the above technical solution, when it is necessary to cut the composite film, the connecting strip can be cut by simply tearing off the retaining sticker.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the heat dissipation sandwich structure metal-based composite film:

[0019] 1. A heat dissipation layer is formed between the surface layer and the bottom layer. A second vent is formed on the bottom layer attached to the equipment, allowing heat to enter the heat dissipation layer through the second limiting hole. Since the second limiting hole is set with a large diameter, heat can be effectively introduced into the heat dissipation layer through the second vent and then discharged through the first limiting hole and the first vent formed on the surface of the surface layer. The first vent is set with a smaller diameter to prevent a large amount of external dust from falling into the heat dissipation layer and causing blockage. This demonstrates that the metal-based composite film has good heat dissipation function, effectively protecting the metal-based composite film from thermal breakdown. At the same time, it protects the equipment from high temperature affecting the normal operation of the internal parts and extends the service life of the internal parts of the equipment.

[0020] 2. Scale strips are provided on the outer surface of the surface layer and the outer surface of the connecting strip, allowing workers to know the length of one end of the surface layer and the other end of the connecting strip. This avoids waste caused by excessive cutting of the metal-based composite film, demonstrating that the metal-based composite film provides workers with specific lengths. It is very convenient for workers to use, and the length of the metal-based composite film used is very precise.

[0021] 3. An opening is provided on the upper surface of the connecting strip in the connecting mechanism, and a retaining sticker is attached to the upper surface of the opening. When the metal-based composite film needs to be cut, the operator can select the position to be cut according to the scale strip on the surface and the upper surface of the connecting strip, then peel off the retaining sticker on the upper surface of the connecting strip at the selected position, and then tear the connecting strip apart. This demonstrates that the metal-based composite film is easy to cut, which facilitates the cutting of the metal-based composite film by the operator, improves work efficiency, and is very convenient to cut.

[0028] 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.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a heat dissipation sandwich structure metal-based composite film, including a surface layer 1, vent 1 2, scale strip 3, heat dissipation mechanism 4, heat dissipation layer 41, limiting hole 1 42, limiting hole 2 43, bottom layer 5, vent 2 6, adhesive layer 7, connecting mechanism 8, connecting strip 81, opening 82, and stabilizing sticker 83.

[0030] This metal-based composite film exhibits excellent heat dissipation properties, as detailed below:

[0031] The outer surface of the surface layer 1 has vent 2 and a scale strip 3. A heat dissipation mechanism 4 is connected to the inner wall of the surface layer 1, which enables the metal-based composite film to have good heat dissipation performance. The outer surface of the heat dissipation mechanism 4 is connected to the bottom layer 5, and the outer surface of the bottom layer 5 has vent 6. The heat dissipation mechanism 4 consists of a heat dissipation layer 41, a limiting hole 42, and a limiting hole 43. The upper surface of the heat dissipation layer 41 is attached to the lower surface of the surface layer 1. The outer surface of the limiting hole 42 is connected to the inner wall of the vent 2, and one end of the limiting hole 42 is fixedly installed on the upper surface of the heat dissipation layer 41 and communicates with the inner wall of the heat dissipation layer 41. The lower surface of the heat dissipation layer 41 is attached to the upper surface of the bottom layer 5. The outer surface of the limiting hole 43 is connected to the inner wall of the vent 6, and one end of the limiting hole 43 is fixedly installed on the lower surface of the heat dissipation layer 41 and communicates with the inner wall of the heat dissipation layer 41. The outer surface of limiting hole 42 engages with the inner wall of vent 2. The outer surface of limiting hole 43 engages with the inner wall of vent 6.

[0032] In the production of this metal-based composite film, the metal substrate foil and reinforcing material are first fused and arranged in a certain proportion, then placed in a metal sheath and subjected to vacuum static pressure. After heating and pressurizing, surface layer 1 and bottom layer 5 are formed. Finally, surface layer 1 and bottom layer 5 are placed in a designated mold for hot pressing, such as... Figure 1 As shown, this makes Figure 1 The top and bottom sides are hot-pressed together, forming a cavity heat dissipation layer 41 between the surface layer 1 and the bottom layer 5. Then, holes are punched into the outer surfaces of the surface layer 1, the bottom layer 5, and the connecting strip 81. Subsequently, during the winding and packaging of the metal-based composite film, the scale strip 3 and the retaining adhesive 83 are rolled and attached to the outer surfaces of the surface layer 1 and the connecting strip 81, thus producing the metal-based composite film. After the adhesive layer 7 of the metal-based composite film is attached to the surface of the equipment, the heat generated by the equipment during operation will be transferred outwards through the second vent 6 on the outer surface of the bottom layer 5. When heat is transferred outwards from the second vent 6... The heat will enter the interior of the limiting hole 43. When the heat enters the interior of the limiting hole 43, it will be transferred to the heat dissipation layer 41 in the heat dissipation mechanism 4. Since the opening diameter of the second vent 6 is relatively large, it can effectively transfer the heat emitted from the outer surface of the equipment, and then transfer it outward through the limiting hole 42. When the heat is transferred outward from the limiting hole 42, it will be transferred out through the vent 2 on the outer surface of the surface layer 1. Since the opening diameter of the vent 2 is smaller than that of the second vent 6, the vent 2 is more numerous and denser than the second vent 6, which shows that the metal-based composite film has good heat dissipation function.

[0033] This metal-based composite film has the advantage of being easy to cut, as detailed below:

[0034] An adhesive layer 7 is attached to the outer surface of the bottom layer 5. A connecting mechanism 8 is provided on one side of the top layer 1 and the bottom layer 5, and the connecting mechanism 8 allows the metal-based composite film to be easily cut as needed. The connecting mechanism 8 consists of a connecting strip 81, an opening 82, and a retaining sticker 83. The connecting strip 81 is connected to one side of the top layer 1 and the bottom layer 5. A scale strip 3 is provided on the upper surface of the connecting strip 81, and the retaining sticker 83 is attached to the upper surface of the connecting strip 81. An opening 82 is formed on the upper surface of the connecting strip 81. The bottom surface of the retaining sticker 83 is attached to the upper surface of the opening 82.

[0035] Both the outer surface of the surface layer 1 and the connecting strip 81 in the connecting mechanism 8 are provided with scale strips 3 to show the length of the surface layer 1 and the connecting strip 81 to the staff. When the staff uses the metal-based composite film, they need to know the length to use. They can use it according to the length shown on the scale strip 3. When the metal-based composite film needs to be cut, first calculate the length to be used, which is the length of the surface layer 1 plus the length of the connecting strip 81. Then cut the connecting strip 81 that is closest to the cutting position. Before cutting the connecting strip 81, first peel off the retaining sticker 83 from the outer surface of the connecting strip 81 so that the opening 82 loses its fixing effect. At the same time, tear the connecting strip 81 from the middle to complete the cutting of the metal-based composite film.

[0036] Working principle: When using this heat dissipation sandwich structure metal-based composite film, the adhesive layer 7 of the composite film is first attached to the outer surface of the equipment. Heat is discharged from the surface layer 1 through the limiting holes 1 42 and 2 43 on the heat dissipation layer 41 and through the air holes 1 2 and 2 6. When the composite film needs to be cut, the stabilizing sticker 83 is peeled off from the outer surface of the connecting strip 81, and then the connecting strip 81 is peeled off to complete the cutting, which increases the overall practicality.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
