They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] A fan-shaped heat sink aluminum profile includes a base plate 1, a plurality of fins 2 and at least four irregularly shaped fins 3, wherein the base plate 1 includes an arc-shaped portion 11 and at least two flat portions 12;

[0025] The two ends of the arc-shaped portion 11 are respectively connected to the corresponding planar portion 12, and the two planar portions 12 are symmetrically distributed from left to right; four irregularly shaped fins 3 are evenly distributed on the top of the arc-shaped portion 11 along its arc length direction, and fins 2 are evenly distributed between two adjacent irregularly shaped fins 3; the fins 2 are evenly distributed on the top of the two planar portions 12 along their own length direction; the fins 2 and the irregularly shaped fins 3 together form a fan-shaped divergent array structure;

[0026] At least four first buckles 4 are evenly distributed along the arc length direction at the bottom of the arc-shaped surface 11. Second buckles 5 are respectively provided on the inner side of the irregular fins 3 on the left and right sides. A third buckle 6 is provided on the fin 2 located in the middle of the arc-shaped surface 11. The first buckles 4, the second buckles 5 and the third buckles 6 are respectively used to engage with the corresponding installation positions on the fixing frame of the heat sink (not shown in the figure).

[0027] This solution provides a fan-shaped aluminum profile for a heat sink. In this embodiment, for example... Figure 1 As shown, four of the irregularly shaped fins 3 and four of the first latches 4 are provided. Two of the planar portions 12 are provided. Since four irregularly shaped fins 3 are evenly distributed along the arc length of the top of the arc-shaped portion 11, and fins 2 are evenly distributed between adjacent irregularly shaped fins 3, and fins 2 are evenly distributed along their own length on the tops of the two planar portions 12, the uniform distribution of the fins 2 and irregularly shaped fins 3 can guide airflow to form turbulence, enhancing heat exchange efficiency. Since the fins 2 and the irregularly shaped fins 3 together form a fan-shaped divergent array structure, the heat dissipation area can be effectively increased, thereby improving heat dissipation efficiency.

[0028] This solution uses a first clip 4, a second clip 5, and a third clip 6 to achieve a snap-fit ​​connection with the corresponding mounting positions on the radiator's mounting frame. This ensures a stable connection and avoids the disassembly difficulties caused by traditional welding or glue fixing, thereby improving the convenience of installation, maintenance, and replacement.

[0029] Preferably, the irregularly shaped fin 3 includes two first heat dissipation portions 31 and a second heat dissipation portion 32; the bottoms of the two first heat dissipation portions 31 are connected to the top of the arc-shaped surface portion 11, and the tops of the two first heat dissipation portions 31 are connected through the second heat dissipation portion 32, so that the two first heat dissipation portions 31 and the second heat dissipation portion 32 enclose a heat dissipation cavity 30. In this embodiment, as shown... Figure 1 As shown, since the two first heat dissipation parts 31 and the second heat dissipation parts 32 enclose and form a heat dissipation cavity 30, the heat dissipation cavity 30 not only increases the heat dissipation area, but also enhances the thermal convection efficiency due to the turbulence characteristics of the air flow inside the cavity, thereby improving the heat dissipation efficiency.

[0030] Preferably, the bottom of the planar portion 12 is provided with a first positioning groove 7 and a second positioning groove 8, the first positioning groove 7 being located at the end of the planar portion 12, and the second positioning groove 8 being located on one side of the first positioning groove 7. In this embodiment, as... Figure 1As shown, by setting the first positioning groove 7 and the second positioning groove 8, they can be precisely matched with the positioning boss (not shown in the figure) on the fixed frame of the heat sink, forming a "double positioning point" constraint, thereby avoiding the situation of offset or misalignment during the assembly of the heat sink aluminum profile and the fixed frame.

[0031] Preferably, the first buckle 4 has an arc-shaped cross-section, and the diameter D1 of this arc-shaped cross-section is 5.0–7.5 mm. In this embodiment, as shown... Figure 2 As shown, the diameter D1 corresponding to the arc-shaped cross-section of the first buckle 4 is 6.5mm, which not only ensures the snapping stability between the first buckle 4 and the fixed frame, but also utilizes the arc-shaped structural characteristics to disperse assembly stress and avoid deformation of the first buckle 4 due to long-term use.

[0032] Preferably, the second buckle 5 has a circular arc-shaped cross-section, with an outer diameter D2 of 8.0–9.5 mm and an inner diameter D3 of 4.0–5.5 mm. In this embodiment, as shown... Figure 3 As shown, the outer diameter D2 of the arc-shaped cross-section of the second buckle 5 is 8.5 mm, and the inner diameter D3 is 4.2 mm. This not only ensures the stability of the second buckle 5 in engagement with the fixed frame, but also disperses the stress generated during assembly by utilizing the characteristics of the arc-shaped structure, reducing stress concentration and thus effectively avoiding the problem of deformation of the second buckle 5 during long-term use.

[0033] Preferably, the third buckle 6 has a circular arc-shaped cross-section, with an outer diameter D4 of 8.0–9.5 mm and an inner diameter D5 of 4.0–5.5 mm. In this embodiment, as... Figure 4 As shown, the outer diameter D4 of the arc-shaped cross-section of the third buckle 6 is 8.5 mm, and the inner diameter D5 is 4.2 mm. This not only ensures the stability of the connection between the third buckle 6 and the fixed frame, effectively avoiding problems such as loosening or shaking after assembly, but also disperses the stress generated during assembly by utilizing the characteristics of the arc-shaped structure, thereby reducing the risk of deformation or breakage of the third buckle 6 due to stress accumulation during long-term use.

[0034] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
