The temperature continues to rise, seriously affecting the operating performance and stability of electronic components. Therefore, in order to improve heat dissipation performance, current processors are almost all equipped with corresponding heat dissipation devices to operate at normal operating temperatures, thereby avoiding performance degradation or even burning. Existing heat dissipation devices have two methods: active heat dissipation and passive heat dissipation. Passive heat dissipation generally dissipates heat through heat exchange between a heat dissipation substrate and integrally formed heat dissipation fins and the air.

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

[0020] like Figure 1-Figure 5 As shown, a combined heat sink includes a heat conducting plate 1 and a plurality of detachable fins 2 arranged above the heat conducting plate 1. The bottom of the heat conducting plate 1 is fixedly provided with a plurality of contact pieces 5, and the plurality of contact pieces 5 are evenly spaced and distributed. The top surface of the heat conducting plate 1 is recessed inward to form a fixed cavity 7 for accommodating the fins 2. A heat conducting block 6 is welded to the top surface of the heat conducting plate 1. The side of the heat conducting block 6 extends outward to form a plurality of evenly spaced and distributed locking blocks 8. The inner wall of the heat conducting plate 1 is provided with a plurality of evenly spaced and distributed limiting grooves. 10. The opening direction of the limiting groove 10 is opposite to the direction of the locking block 8. The top surface of the heat conducting plate 1 is provided with a plurality of positioning holes 9 arranged at equal intervals. One end of the fin 2 extends outward to form a positioning portion 11. The positioning portion 11 is inserted into the interior of the positioning hole 9. One end of the fin 2 extends outward to form a limiting portion 12. The limiting portion 12 is inserted into the interior of the limiting groove 10. The side surface of the fin 2 is recessed to form a locking groove 13. The locking block 8 is engaged with the locking groove 13.

[0021] The four corner edges of the heat conducting plate 1 extend outward to form a bottom plate 3, and the surface of the bottom plate 3 is provided with screw holes 4 for fixing screws. The height of the heat conducting plate 1 is the same as that of the heat conducting block 6, and the number of the positioning holes 9, the limiting grooves 10 and the locking blocks 8 are the same. The bottom plate 3 and the contact piece 5 are all on the same horizontal plane. The heat conducting plate 1, the contact piece 5, the heat conducting block 6 and the fin 2 are all made of metal copper. The contact pieces 5 arranged equidistantly at the bottom of the heat conducting plate 1 ensure sufficient contact between the heat sink and the heat source, thereby improving the heat exchange efficiency. At the same time, the bottom plate 3 extending from the four corners of the heat conducting plate 1 and the screw holes 4 thereon make it easy to firmly mount the heat sink on the heat source by screws, thereby enhancing the overall stability of the heat sink. Metal copper is used. The heat conducting plate 1, contact piece 5, heat conducting block 6 and fin 2 are composed. Since copper has good thermal conductivity, it can quickly conduct heat from the heat source to the heat dissipation surface, effectively reducing the temperature of the heat source and accelerating the heat dissipation of the heat source. The heat conducting plate 1, heat conducting block 6 and fin 2 are all arranged with equidistant and aligned snap blocks 8, limit grooves 10, positioning holes 9 and other structures, so that the fin 2 can be better fixed on the heat conducting plate 1, which is convenient for flexible adjustment of the number and layout of the fin 2 according to specific heat dissipation requirements, greatly improving the maintainability of the heat sink. The bottom plate 3 and the contact piece 5 are kept on the same horizontal plane, which simplifies the alignment and fixing steps of the heat sink during installation, making it easier to adapt to various heat source surfaces and improving the versatility of the product.

[0022] A combined heat sink of the present embodiment realizes a modular design of the heat sink by arranging a plurality of detachable fins 2 on the heat conducting plate 1, which facilitates the disassembly and assembly of the heat sink. By arranging a positioning portion 11 to be inserted into the interior of the positioning hole 9, and a limiting portion 12 to be inserted into the interior of the limiting groove 10, the snap block 8 is snap-connected with the snap groove 13, so that the number and layout of the fins 2 can be flexibly adjusted according to specific heat dissipation requirements, thereby greatly improving the maintainability of the heat sink. When individual fins 2 are damaged, they can be replaced individually without replacing the entire heat sink, thereby reducing maintenance costs.

[0023] When the heat sink 1 is mounted on the heat source, the heat conducting plate 1 is fitted with the heat source so that the contact piece 5 contacts the surface of the heat source, and the screw is inserted into the screw hole 4 so that the bottom plate 3 is fixed to the heat source, thereby fixing the heat conducting plate 1. After fixing the heat conducting plate 1, the fin 2 can be fixed by manually inserting the fin 2 directly into the fixing cavity 7, so that the positioning part 11 is inserted into the inside of the positioning hole 9, the limiting part 12 is inserted into the inside of the limiting groove 10, and the snap block 8 is snap-connected with the snap groove 13, thereby fixing the fin 2. When the heat source generates a large amount of heat, the contact piece 5 contacts the heat source, and the heat generated by the heat source is conducted to the heat conducting plate 1 and the heat conducting block 6 through the contact piece 5, and the heat is dissipated again through the fin 2, thereby achieving heat dissipation of the heat source. When individual fins 2 are damaged, the fins 2 can be replaced individually without replacing the entire heat sink. At the same time, it is convenient to disassemble and assemble the fins 2, and it is convenient to clean the dust on the fins 2 later.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
