Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The following is combined with Figures 1 to 6 Embodiments of the present invention will be described.

[0018] Please refer to Figures 1 to 5 This embodiment relates to a heat dissipation structure, which includes a heat dissipation base 1, a heat pipe 3, and multiple fin units 2. The top surface of the heat dissipation base 1 is provided with a groove; Each fin unit 2 includes a first fin 21 and a second fin 22. The second fin 22 is vertically arranged, and the top edges of the first fin 21 and the second fin 22 are fixedly connected. The first fin 21 is horizontally arranged, and the second fin 22 has a first opening structure. Some of the first fins 21 have a second opening structure. All the first opening structures and all the second opening structures form a first channel 4. Each first fin 21 is fixedly connected to the bottom surface of the heat dissipation base 1. The first fin 21 has a first notch 210, and the second fin 22 has a second notch 220. The first notch 210 and the second notch 220 are connected. The second fin 22 has an upwardly extending first protrusion 221, which is fixed to the corresponding second notch 220. The first fin 21 has a position corresponding to the first notch 210. The first claw 211 is fixedly connected to the first plate 21. The first claw 211 extends in a direction away from the first notch 210. The first claw 211 has a third notch 2110, which is connected to the first notch 210. The end of the third notch 2110 away from the first notch 210 is used to accommodate the first protrusion 221 of the preceding fin unit 2. The end of the third notch 2110 near the first notch 210, the first notch 210, and the second notch 220 form a fourth notch. The fourth notch is used to accommodate the first claw 211 of the following fin unit 2. The first notch 210, the second notch 220, the third notch 2110, the first protrusion 221, and the first claw 211 are each provided in a plurality of equal numbers. The heat pipe 3 includes a heat-conducting section and a heat-dissipating section that are fixedly connected.

The heat-conducting section of the heat pipe 3 is mounted on the heat dissipation base 1, and the heat dissipation section is mounted in the fin units 2. The heat dissipation fins adopt a modular design, with each fin unit 2 having several corresponding and cooperating first notches 210, second notches 220, third notches 2110, first protrusions 221, and first claws 211. This allows the multiple fin units 2 to be detachably installed and securely connected, facilitating the disassembly, assembly, and replacement of the fin units 2. Specifically, the upper surface of the heat dissipation base plate contacts the object requiring heat dissipation. In the laser field, the upper surface of the heat dissipation base plate can be mounted on the laser housing, or a PCB and other heat-generating devices can be mounted on the upper surface of the heat dissipation base plate. The first fin 21 of each fin unit 2 is fixedly connected to the heat dissipation base 1 and can be fixed to the corresponding position on the heat dissipation base plate by brazing, improving the overall heat dissipation efficiency. The fin units 2 and the heat dissipation sections can also be fixed by brazing. The heat pipe 3 connects the heat dissipation base plate and the fin units 2 in series, further improving the heat dissipation efficiency and stability of the heat dissipation structure. The groove may contain an arc-shaped groove surface to fit the heat-conducting section of the heat pipe 3. The first opening structure and the second opening structure are adapted to the shape and size of the heat pipe 3, and fin units 2 with different opening structures are arranged as needed to improve the adaptability of the heat dissipation structure.

[0020] Please refer to Figure 5 In some embodiments, the first claw 211 includes a first sub-claw 2111 and a second sub-claw 2112. The first sub-claw 2111 and the second sub-claw 2112 are respectively fixedly connected to the first piece 21. A gap is formed between the first sub-claw 2111 and the second sub-claw 2112.

The first sub-claw 2111 is provided with a first notch, and the second sub-claw 2112 is provided with a second notch. The first notch and the second notch form the third notch 2110.

[0021] In this embodiment, the first claw 211 is further subdivided into a first sub-claw 2111 and a second sub-claw 2112. The sub-claw structure has a certain elasticity, which can improve the installation stability of the fin unit 2, facilitate the positional correspondence between the fin units 2, and improve the overall mechanical strength and vibration resistance of the heat sink.

[0022] Please refer to Figure 5In some embodiments, the first split claw 2111 includes a first front portion and a first rear portion fixedly connected, the first rear portion being fixedly connected to the first piece 21, the first rear portion being located between the first front portion and the first piece 21, and the width of the first front portion being smaller than the width of the first rear portion. The second split claw 2112 includes a second front portion and a second rear portion fixedly connected, the second rear portion being fixedly connected to the first piece 21, the second rear portion being located between the first front portion and the first piece 21, and the width of the second front portion being smaller than the width of the second rear portion. The width of the third notch 2110 is smaller than the width of the first notch 210. The third notch 2110 is used to accommodate the first front portion and the second front portion of the rear fin unit 2, and the first notch 210 is used to accommodate the first rear portion and the second rear portion of the rear fin unit 2.

[0023] In this embodiment, the width difference between the front and rear parts of the first claw 2111 and the second claw 2112, as well as the design of the matching third notch 2110 and the first notch 210, ensure reliable locking between the fins, facilitate installation and disassembly, prevent the fin unit 2 from shifting due to vibration or thermal expansion and contraction, and improve the long-term stability of the heat dissipation structure.

[0024] In some embodiments, the first opening structure is a through hole or a notch, and the second opening structure is a notch. In this embodiment, the first opening structure is flexibly configured to adapt to the shape and size of the heat pipe 3, which is simple in design and easy to mass-produce.

[0025] Please refer to Figure 6 In some embodiments, each fin unit 2 further includes a third piece 23, which is fixedly connected to the bottom edge of the second piece 22. The third piece 23 is arranged laterally and extends along the extension direction of the first piece 21. The third piece 23 has a fifth notch, and the second piece 22 has a sixth notch. The fifth notch and the sixth notch are connected. The second piece 22 has an upwardly extending second protrusion, which is fixed to the corresponding sixth notch. The second piece 22 has a second claw 231 corresponding to the position of the sixth notch. The second claw 231 extends in a direction away from the sixth notch and has a seventh notch, which is connected to the fifth notch. The end of the seventh notch away from the fifth notch is used to accommodate the second protrusion of the preceding fin unit 2. The end of the seventh notch near the fifth notch, the fifth notch, and the sixth notch together form an eighth notch, which is used to accommodate the second claw 231 of the following fin unit 2. The fifth notch, the sixth notch, the seventh notch, the second protrusion, and the second claw 231 are provided in multiples and in equal numbers.

[0026] In this embodiment, by setting a third piece 23, and several corresponding fifth notches, sixth notches, seventh notches, second protrusions and second claws 231, the fin unit 2 is stably connected in multiple layers, enhancing the overall structural stability.

[0027] Please refer to Figure 1 and Figure 3 In some embodiments, the top surface of the heat-conducting section is a plane. In this embodiment, the top surface of the heat-conducting section is a plane, forming a plane with the upper surface of the heat dissipation base 1, and comes into contact with the item that needs heat dissipation. This is beneficial to the structural stability of the heat dissipation structure and the item that needs heat dissipation, and improves the heat dissipation efficiency.

[0028] In some embodiments, the heat sink 1 and all the fin units 2 are made of AL6063. Traditional shovel teeth in the prior art often use AL1050 or AL1060 materials, which have long processing cycles, high costs, and relatively low strength. In this embodiment, AL6063 material is used, which has good machinability and is lightweight.

[0029] In some embodiments, the fin unit 2 is manufactured by stamping. Stamping results in high strength for the fin unit 2, ensuring dimensional accuracy and batch consistency.

[0030] In some embodiments, the thickness of the fin unit 2 is 0.4mm-1mm, and the spacing between the second plates 22 of adjacent fin units 2 is 1mm-3mm. In this embodiment, the preferred thickness of the fin unit 2 is 0.4mm-1mm, and the spacing between the second plates 22 of adjacent fin units 2 is 1mm-3mm, which maintains the stability of the fin structure while optimizing airflow and improving heat dissipation efficiency.
