Utility Model Content

[0003] The purpose of the utility model is to provide a graphite aluminum temperature-averaging fin to solve the problem raised in the above-mentioned background technology that the existing heat fins are mainly made of metal aluminum, but their thermal conductivity and temperature-averaging performance are not ideal and cannot meet the heat dissipation requirements of modern high-tech products.

[0004] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0005] The utility model discloses a graphite aluminum temperature-averaging fin, comprising a temperature-averaging fin body, a positioning groove and graphite;

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-3 As shown, this embodiment is a graphite aluminum temperature-averaging fin, comprising a temperature-averaging fin body 1, a positioning groove 3 and graphite 2;

[0032] The positioning groove 3 is opened in the middle of the upper front end of the temperature-averaging fin body 1, and the graphite 2 is pressed into the middle of the positioning groove 3 at high temperature;

[0033] The positioning groove 3 is used to fix the graphite 2. The temperature-averaging fin body 1 and the graphite 2 form a heat dissipation structure. The graphite 2 has a high thermal conductivity, which can effectively improve the heat dissipation performance. Compared with the traditional aluminum fins, the graphite aluminum fins have a higher thermal conductivity, which can transfer heat to the fin surface faster to achieve rapid heat dissipation. The high-temperature pressing ensures the close combination between the graphite 2 and the temperature-averaging fin body 1, which reduces the contact thermal resistance and increases the heat transfer capacity.

[0034] The temperature-averaging fin body 1 is made of aluminum, and the temperature-averaging fin body 1 is in a comb shape;

[0035] Aluminum is lightweight and has a surface oxidation treatment, making it highly corrosion-resistant.

[0036] The temperature-averaging fin body 1 includes a connecting frame 11 and fins 12;

[0037] The fins 12 are threaded equidistantly on the middle of the lower end of the connecting frame 11;

[0038] The fins 12 and the connecting frame 11 are combined to form a temperature-averaging fin body 1;

[0039] A threaded column 13 is fixed to the middle of the upper end of the fin 12, and the upper end of the threaded column 13 is threaded into a threaded groove 14 equidistantly provided in the middle of the lower end of the connecting frame 11;

[0040] The threaded connection between the threaded column 13 and the threaded groove 14 can fix the fin 12 and the connecting frame 11. The threaded connection method can facilitate the disassembly and assembly of the structure.

[0041] A cavity 21 is formed in the middle of the connecting frame 11, and the cavity 21 passes through the end of the connecting frame 11;

[0042] The cavity 21 accommodates and stores the multiple fins 12 after disassembly;

[0043] Working principle: insert the threaded columns 13 on the upper ends of the multiple fins 12 into the threaded grooves 14 in sequence, and apply tightening force to connect and fix the connecting frame 11 and the fins 12, and put graphite 2 into the positioning grooves 3 and fix them by high temperature pressing;

[0044] Next, graphite 2 and the temperature-averaging fin body 1 form a heat dissipation structure. Graphite 2 has a high thermal conductivity, which can effectively improve the heat dissipation performance. Compared with traditional aluminum fins, graphite aluminum fins have a higher thermal conductivity and can conduct heat to the fin surface faster, thereby achieving rapid heat dissipation.

[0045] This step achieves rapid heat dissipation, is light in weight, and is easy to use.

[0046] See also Figure 4 As shown, this embodiment is based on the above-mentioned embodiment 1 and further includes a limiting structure;

[0047] The limiting structure includes an external limiting block 22, a movable spring 23 and an internal limiting block 24;

[0048] The external limit block 22 is symmetrically clamped in the middle of the cavity 21, and the ends of the movable spring 23 are respectively sleeved on the inner sides of the external limit block 22 and the internal limit block 24;

[0049] The external limit block 22 blocks the outer end of the cavity 21 to prevent the fin 12 received therein from falling off, and the movable spring 23 fixes the external limit block 22 and the internal limit block 24. The internal limit block 24 is used to structurally limit the fin 12 received in the cavity 21, and the movable spring 23 relies on its own elastic expansion and contraction to meet the requirements for limiting the fin 12.

[0050] A protruding column is fixed at the end of the movable spring 23, and the protruding column is sleeved in the sleeve openings opened on the inner side of the external limit block 22 and the internal limit block 24;

[0051] The sleeve connection between the protruding column and the sleeve fixes the movable spring 23, the external limit block 22 and the internal limit block 24;

[0052] Working principle: After disassembling multiple fins 12, place them inside the cavity 21;

[0053] At this time, the external limit block 22, the movable spring 23, and the internal limit block 24 are fixed by the sleeve connection between the convex column and the sleeve, and the internal limit block 24 is placed into the cavity 21. Under the action of the inward force, relying on the elasticity of the movable spring 23, while ensuring that the internal limit block 24 is in contact with the fin 12 in the storage, the external limit block 22 is clamped at the end of the cavity 21;

[0054] This step improves the applicability and functionality of the connecting frame 11 .

[0055] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
