[0002] A graphene heat sink is a highly efficient heat dissipation device made using the excellent thermal conductivity of graphene. As a two-dimensional material composed of a single layer of carbon atoms, graphene's honeycomb lattice structure allows for rapid lateral heat diffusion. This heat sink combines a graphene film or composite material with the heat-generating element, enabling rapid and uniform distribution of localized hotspot temperatures, resulting in heat dissipation efficiency several times higher than traditional metals.

[0003] A graphene heat sink was found (authorization announcement number: CN 209749023 U), which "comprising: a first aluminum alloy heat sink, a second graphene heat sink, a third aluminum alloy heat sink, a plurality of graphene heat dissipation blades, and a fixing member; the second graphene heat sink is clamped and disposed between the first aluminum alloy heat sink and the third aluminum alloy heat sink by the fixing member; and the graphene heat dissipation blades are spaced apart on the surface of the third aluminum alloy heat sink away from the second graphene heat sink; the surface of the first aluminum alloy heat sink away from the second graphene heat sink is in contact with the heat sink of the electronic device."

[0004] Based on the aforementioned technologies, the applicant believes that the aluminum alloy heat sink and graphene heat sink in the above technologies are fixed together by bolts, which requires the use of external tools during installation. Furthermore, cleaning, repairing, and replacing the graphene heat sink fins is cumbersome and not conducive to quick installation and disassembly. In response to the above problems, we have launched a staggered heat dissipation graphene heat sink. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A staggered heat dissipation graphene radiator includes aluminum alloy heat sinks. The tops of the aluminum alloy heat sinks are symmetrically fixedly connected to mounting brackets. Slots are provided on the sides of the two mounting brackets that are close to each other. A heat dissipation mechanism is provided on the top of the aluminum alloy heat sinks. The heat dissipation mechanism includes a mounting assembly and a graphene heat dissipation assembly, which cooperate with each other. The mounting assembly includes an L-shaped fixing bracket, which is fixedly connected to the top of the mounting bracket.

Positioning holes are equally spaced on both sides of the graphene heat dissipation plate, and graphene heat dissipation fins are fixedly connected to the top of the graphene heat dissipation plate at equal intervals.

[0013] In a preferred embodiment, the graphene heat sink fins have ventilation slots inside, and the aluminum alloy heat sink fins have heat dissipation slots at equal intervals at their bottom.

[0014] The graphene heat sink fins have ventilation slots inside, which, together with the heat sink slots at the bottom of the aluminum alloy heat sink, form a multi-channel heat dissipation structure, enhancing air convection and further improving heat dissipation performance.

[0015] In a preferred embodiment, the size of the positioning hole matches the size of the positioning post, and the positioning hole and the positioning post are used in conjunction with each other.

[0016] The positioning holes and positioning posts are matched in size to ensure accurate positioning of the graphene heat sink during installation, prevent displacement, and improve structural reliability.

[0017] In a preferred embodiment, L-shaped mounting plates are symmetrically fixedly connected to both sides of the aluminum alloy heat sink, and mounting holes are provided inside the L-shaped mounting plates.

[0018] The L-shaped mounting plate and mounting holes facilitate the overall fixation of the heat sink to electronic devices, enhancing installation stability and making it suitable for various application scenarios.

Ventilation slots are created inside the graphene heat sink fins, working in conjunction with the heat dissipation slots at the bottom of the aluminum alloy heat sink to form a multi-channel heat dissipation structure, enhancing air convection and further improving heat dissipation performance. The positioning holes and positioning posts are sized to ensure precise positioning of the graphene heat sink during installation, preventing misalignment and improving structural reliability. The L-shaped mounting plate and mounting holes facilitate the overall fixation of the heat sink to electronic equipment, enhancing installation stability and making it suitable for various application scenarios.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] The staggered heat dissipation graphene heat sink disclosed in this utility model is mainly applied to graphene heat sink applications.

[0030] Reference Figures 1-5 A staggered heat dissipation graphene heat sink includes an aluminum alloy heat sink 1. A mounting bracket 2 is symmetrically fixedly connected to the top of the aluminum alloy heat sink 1. Slots 3 are provided on the sides of the two mounting brackets 2 that are close to each other. A heat dissipation mechanism is provided on the top of the aluminum alloy heat sink 1. The heat dissipation mechanism includes a mounting component and a graphene heat dissipation component. The mounting component and the graphene heat dissipation component work together. The mounting component includes an L-shaped fixing bracket 41, which is fixedly connected to the top of the mounting bracket 2. Positioning posts 42 are equidistantly slidably connected inside the two L-shaped fixing brackets 41. A connecting plate 43 is fixedly connected to the top of the positioning post 42. A limit plate 45 is fixedly connected to the outside of the positioning post 42. A pressing spring 44 is sleeved on the outside of the positioning post 42. The graphene heat dissipation assembly includes a graphene heat sink 47, which is inserted into the slot 3. Positioning holes 49 are equally spaced on both sides of the graphene heat sink 47. Graphene heat dissipation fins 48 are fixedly connected to the top of the graphene heat sink 47 at equal intervals. The graphene heat dissipation fins 48 are staggered.

[0031] This embodiment utilizes the ultra-high thermal conductivity of graphene material to achieve rapid lateral heat diffusion. The staggered distribution of graphene heat dissipation fins 48 significantly increases the heat dissipation surface area, while the ventilation slots 410 inside create a turbulence effect. Combined with the heat dissipation slots 5 at the bottom of the aluminum alloy heat sink 1, a multi-channel airflow circulation is formed, significantly enhancing the forced convection heat dissipation effect. In the installation mechanism, the pressing spring 44 continuously applies pressure to keep the limiting plate 45 tightly pressing the graphene heat dissipation plate 47, ensuring close contact of the thermal interface. The precise fit between the positioning post 42 and the positioning hole 49 ensures installation stability and prevents thermal expansion displacement. When maintenance is required, the user only needs to pull the connecting plate 43 with the anti-slip grip 411 to compress the pressing spring 44, easily removing the graphene heat dissipation component for cleaning or replacement. Through the designed installation mechanism, compared with traditional heat sinks, the operating temperature of the equipment can be effectively reduced, and the graphene heat dissipation fins 48 can be quickly replaced and repaired without the need for external tools. The structure is simple and highly practical.

[0032] In the above technical solution, considering that the aluminum alloy heat sink and the graphene heat sink are fixed together by bolts, requiring external tools during installation, and that cleaning, repairing, and replacing the graphene heat sink fins is cumbersome and not conducive to quick installation and disassembly, the following specific operation is proposed to solve these problems:

[0033] Reference Figures 1-5 In a preferred embodiment, a pull bracket 46 is fixedly connected to the top of the two positioning posts 42, and an anti-slip handle 411 is fixedly connected to the outside of the pull bracket 46. Ventilation slots 410 are formed inside the graphene heat sink fins 48, and heat dissipation slots 5 are equidistantly formed at the bottom of the aluminum alloy heat sink 1. The size of the positioning hole 49 matches the size of the positioning post 42, and the positioning hole 49 and the positioning post 42 cooperate with each other. L-shaped mounting plates 6 are symmetrically fixedly connected to both sides of the aluminum alloy heat sink 1, and mounting holes 7 are formed inside the L-shaped mounting plates 6.

[0034] In this embodiment, the design of the pull bracket 46 and the anti-slip grip 411 facilitates manual operation of the positioning post 42, making the assembly and disassembly of the graphene heat sink 47 more convenient and improving the user experience. Ventilation slots 410 are formed inside the graphene heat sink fins 48, which, together with the heat dissipation slots 5 at the bottom of the aluminum alloy heat sink 1, form a multi-channel heat dissipation structure, enhancing air convection and further improving heat dissipation performance. The positioning hole 49 matches the size of the positioning post 42, ensuring precise positioning of the graphene heat sink 47 during installation, preventing displacement, and improving structural reliability. The L-shaped mounting plate 6 and mounting holes 7 facilitate the overall fixation of the heat sink to electronic equipment, enhancing installation stability and making it suitable for various application scenarios.

[0035] Working principle: When this graphene heat sink is working, the heat generated by the electronic components is first conducted to the aluminum alloy heat sink 1. Its high thermal conductivity allows the heat to quickly diffuse to the entire structure. The heat is then transferred to the graphene heat sink 47 through the slot 3. Utilizing the ultra-high thermal conductivity of graphene material, rapid lateral heat diffusion is achieved. The staggered distribution of graphene heat sink fins 48 significantly increases the heat dissipation surface area. At the same time, the ventilation slots 410 inside create a turbulence effect, which, together with the heat dissipation slots 5 at the bottom of the aluminum alloy heat sink 1, forms a multi-channel airflow circulation, significantly enhancing the forced convection heat dissipation effect. In the installation mechanism... The pressing spring 44 continuously applies pressure to keep the limiting plate 45 tightly pressing the graphene heat sink 47, ensuring close contact of the thermal interface. The precise fit between the positioning post 42 and the positioning hole 49 ensures installation stability and prevents thermal expansion displacement. When maintenance is required, the user only needs to pull the connecting plate 43 with the non-slip grip 411 to compress the pressing spring 44 and easily remove the graphene heat sink component for cleaning or replacement. The entire heat dissipation system achieves efficient heat conduction and optimized aerodynamic heat dissipation path through the metal-graphene composite heat dissipation structure, which can effectively reduce the operating temperature of the equipment compared with traditional heat sinks.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
