Description

Technical Field

[0001] This utility model relates to the field of heat-conducting sheet technology, and in particular to a heat-conducting sheet with a scratch-resistant structure. Background Technology

[0002] Thermal pads are a key material for heat dissipation in electronic devices. They are typically made of materials with high thermal conductivity. Their main function is to quickly conduct heat away by tightly fitting the heat-generating element to the heat sink, thereby reducing the device temperature and preventing overheating damage. To improve durability, modern thermal pads often adopt a scratch-resistant structural design to avoid performance degradation due to friction or external forces during installation or use. This structure not only extends the service life of the thermal pad but also ensures long-term stable heat dissipation. They are widely used in computers, communication equipment, new energy vehicles, and other fields.

[0003] Traditional heat sinks use an integrated scratch-resistant structure. However, if the splicing process is not precise enough, the scratch-resistant coating may not be evenly covered at the seams, resulting in unprotected areas. This exposes the substrate at the seams, making it susceptible to scratches or wear from external hard objects. Once an integrated scratch-resistant heat sink is damaged, the entire unit needs to be replaced, rather than individual units. This increases the cost of repair and replacement and requires a significant amount of time for disassembly and installation.

[0004] Therefore, to address the problem that the traditional heatsink uses an integrated anti-scratch structure, resulting in uneven coverage of the anti-scratch coating at the seams and the inability to replace individual components, thus increasing maintenance and replacement costs, a fully covered heatsink with an anti-scratch structure that can be quickly assembled can be designed to solve the above problems. Utility Model Content

[0005] To overcome the problem that traditional heat sinks use an integrated anti-scratch structure, which results in the anti-scratch coating not being evenly covered at the seams, making it impossible to replace them individually and increasing the cost of maintenance and replacement.

[0006] The technical solution of this utility model is as follows: a heat-conducting sheet with a scratch-resistant structure, including a heat-conducting base plate; and heat-conducting fins, with a plurality of heat-conducting fins movably connected above the heat-conducting base plate, a scratch-resistant coating fixedly connected to both sides of the heat-conducting fins, two fixed supports fixedly connected to both ends of the heat-conducting fins, a hollow ring fixedly connected below the fixed supports, an upper connecting shell fixedly connected below the hollow ring, a sliding shell slidably connected to the outside of the upper connecting shell, a lower connecting shell movably connected below the upper connecting shell, and the lower connecting shell fixedly connected to the heat-conducting base plate.

[0007] Preferably, the heat-conducting base plate is installed on the component that needs to be cooled by heat conduction. The upper connecting shells on both sides of the heat-conducting fin plate are inserted into the lower connecting shell. The operator slides the shell to quickly fix the upper connecting shell onto the lower connecting shell. The heat-conducting fin plate disperses the heat of the heat-conducting base plate, accelerating the heat conduction speed. At the same time, a scratch-resistant coating is used to protect the heat-conducting fin plate.

[0008] Preferably, one end of the first reset spring is fixedly connected inside the upper connecting housing, and the other end of the first reset spring is fixedly connected to the upper connecting post, which is slidably connected to the hollow ring.

[0009] Preferably, a locking buckle is fixedly connected to the inner side of the sliding housing, and one end of a self-locking spring is fixedly connected to the inner side of the locking buckle, while the other end of the self-locking spring is fixedly connected to the lower connecting housing.

[0010] Preferably, a locking ring is fixedly connected to the upper part of the lower connecting housing, and several self-locking balls are slidably connected on the locking ring.

[0011] Preferably, one end of the second return spring is fixedly connected to the lower connecting housing, and the other end of the second return spring is fixedly connected to the lower connecting post.

[0012] Preferably, the heat-conducting base plate is provided with several connecting grooves, and heat-conducting fins are slidably connected to the connecting grooves. Movable cylindrical grooves are provided on both sides of the connecting grooves, and lower connecting columns are slidably connected in the movable cylindrical grooves.

[0013] Preferably, two fixed side plates are fixedly connected to the top of the heat-conducting base plate, sliding side plates are slidably connected to both sides of the fixed side plates, and four mounting seats are fixedly connected around the heat-conducting base plate.

[0014] The beneficial effects of this utility model are:

[0015] Multiple heat-conducting fins are designed to connect to the heat-conducting base plate, which not only eliminates unprotected areas but also accelerates heat conduction efficiency and quickly disperses heat from the base plate. At the same time, the self-locking devices at both ends of the heat-conducting fins enable quick installation and removal, allowing for rapid replacement of specific damaged fins and avoiding the need for complete replacement. This saves on maintenance costs and speeds up maintenance efficiency. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a heat-conducting sheet with a scratch-resistant structure, including a heat-conducting base plate 1 and heat-conducting fins 2. Several heat-conducting fins 2 are movably connected above the heat-conducting base plate 1. A scratch-resistant coating 3 is fixedly connected to both sides of the heat-conducting fins 2. Two fixed supports 4 are fixedly connected to both ends of the heat-conducting fins 2. A hollow ring 5 is fixedly connected below the fixed supports 4. An upper connecting shell 6 is fixedly connected below the hollow ring 5. A sliding shell 9 is slidably connected to the outside of the upper connecting shell 6. A lower connecting shell 14 is movably connected below the upper connecting shell 6 and fixedly connected to the heat-conducting base plate 1. The heat-conducting base plate 1 is installed on the component requiring heat conduction and cooling. The upper connecting shells 6 on both sides of the heat-conducting fins 2 are inserted into the lower connecting shell 14. The operator quickly fixes the upper connecting shells 6 onto the lower connecting shell 14 using the sliding shells 9. The heat-conducting fins 2 disperse the heat from the heat-conducting base plate 1, accelerating the heat conduction speed, while the scratch-resistant coating 3 protects the heat-conducting fins 2.

[0024] Please see Figures 2-4In this embodiment, one end of a first return spring 7 is fixedly connected inside the upper connecting housing 6, and the other end of the first return spring 7 is fixedly connected to an upper connecting post 8. The upper connecting post 8 is slidably connected to the hollow ring 5. When the upper connecting housing 6 is installed, the first return spring 7 is compressed, and the first return spring 7 drives the upper connecting post 8 to slide in the hollow ring 5. When the upper connecting housing 6 is removed, the first return spring 7 automatically returns to its original position, and the upper connecting post 8 automatically pops out. A locking buckle 10 is fixedly connected to the inner side of the sliding housing 9, and one end of a self-locking spring 11 is fixedly connected to the inner side of the locking buckle 10. The other end of the self-locking spring 11 is fixedly connected to the lower connecting... On the housing 14, when the operator pushes the sliding housing 9, it causes the locking buckle 10 to move, and at the same time, it causes the self-locking spring 11 to self-lock, fixing the position of the locking buckle 10. A locking ring 12 is fixedly connected above the lower connecting housing 14. Several self-locking balls 13 are slidably connected on the locking ring 12. When the locking buckle 10 moves to the position of the locking ring 12, the locking buckle 10 pushes the self-locking balls 13 on the locking ring 12 to apply pressure inward, locking the upper connecting housing 6 inside. When the locking buckle 10 leaves the position of the locking ring 12, the self-locking balls 13 automatically release outward, and the upper connecting housing 6 also releases.

[0025] Please see Figures 1-5 In this embodiment, one end of a second return spring 15 is fixedly connected to the lower connecting housing 14, and the other end of the second return spring 15 is fixedly connected to the lower connecting post 16. When the upper connecting housing 6 is connected above the lower connecting housing 14, the second return spring 15 is compressed, and the lower connecting post 16 and the upper connecting post 8 are joined together at the top. The heat-conducting base plate 1 is provided with a plurality of connecting grooves 101, and heat-conducting fins 2 are slidably connected to the connecting grooves 101. Movable cylindrical grooves 102 are provided on both sides of the connecting grooves 101, and the lower connecting post 16 is slidably connected in the movable cylindrical grooves 102. The heat-conducting fins 2 are inserted into the connecting grooves 101. Positioning is performed so that when pressure is applied to the lower connecting column 16, the lower connecting column 16 slides in the movable cylindrical groove 102 without causing motion interference. Two fixed side plates 17 are fixedly connected above the heat-conducting base plate 1, and sliding side plates 18 are slidably connected to both sides of the fixed side plates 17. Four mounting seats 19 are fixedly connected around the heat-conducting base plate 1. The fixed side plates 17 and sliding side plates 18 protect the heat-conducting fin plate 2 from scratches. At the same time, the heat-conducting fin plate 2 can be installed by removing the sliding side plates 18 without causing motion interference. The heat-conducting base plate 1 is installed on the workpiece that needs to be cooled by heat conduction using the mounting seats 19.

[0026] During operation, the heat-conducting base plate 1 is installed on the workpiece requiring heat conduction and cooling via the mounting base 19. The sliding side plate 18 is then removed and installed on the heat-conducting fin plate 2. The upper connecting housing 6 on both sides of the heat-conducting fin plate 2 is inserted into the lower connecting housing 14, compressing the first return spring 7. The first return spring 7 drives the upper connecting post 8 to slide in the hollow ring 5. Simultaneously, the lower connecting post 16 and the upper connecting post 8 are attracted together. The second return spring 15 is compressed, causing the lower connecting post 16 to slide in the movable cylindrical groove 102. The operator moves the locking buckle 10 via the sliding housing 9, simultaneously activating the self-locking spring. Spring 11 self-locks and fixes the position of locking buckle 10. Locking buckle 10 pushes self-locking ball 13 on locking ring 12 to apply pressure inward, locking the upper connecting shell 6 inside, thus fixing the heat-conducting fin plate 2. The heat-conducting fin plate 2 disperses the heat of the heat-conducting base plate 1, accelerating the heat conduction speed. At the same time, the scratch-resistant coating 3 protects the heat-conducting fin plate 2. When the heat-conducting fin plate 2 needs to be replaced, push sliding shell 9 so that locking buckle 10 leaves the position of locking ring 12. Self-locking ball 13 automatically releases outward, and upper connecting shell 6 also releases, allowing the heat-conducting fin plate 2 to be removed.

[0027] Through the above steps, multiple heat-conducting fins 2 are designed and connected to the heat-conducting base plate 1. This design eliminates unprotected areas, accelerates heat conduction efficiency, and quickly disperses heat from the heat-conducting base plate 1. Simultaneously, the self-locking devices at both ends of the heat-conducting fins 2 enable rapid installation and removal, allowing for quick replacement of specific damaged heat-conducting fins 2. This avoids the need for complete replacement, saving maintenance costs and increasing maintenance efficiency. It also addresses the problem of traditional heat-conducting sheets using an integrated anti-scratch structure, which results in uneven coverage of the anti-scratch coating at the seams, preventing targeted replacement and increasing maintenance costs.
