Description

Technical Field

[0001] The utility model relates to the technical field of lamp heat sinks, and particularly relates to a lamp heat sink. Background Art

[0002] Traditional lamps use metal halide lamps or energy-saving lamps as light sources. Since they are far inferior to LED-based lamps in terms of energy conservation, environmental protection performance, and service life, LED lamps are now commonly used to replace traditional lamps. However, LED lamps are affected by the working environment temperature. Due to the small volume of the lamp body, high-power LED lamps generate more heat, and high temperatures will cause an increase in LED light attenuation and reduce the service life of LED lamps.

[0003] For traditional lamp heat sinks, their fins and heat dissipation tube columns adopt an integrated structure. Therefore, the processing difficulty is relatively high, resulting in a relatively high production cost for the entire heat sink. Moreover, the ratio of the number of fins to the number of heat dissipation tube columns is fixed, and the number of fins cannot be adjusted according to actual usage requirements. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a lamp heat sink, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions:

[0006] It includes: a heat dissipation column and a heat dissipation fin component.

[0007] It further includes: the heat dissipation fin component includes a main heat dissipation fin and a fin connecting plate fixedly connected to the main heat dissipation fin, and the heat dissipation fin component is connected to the heat dissipation fin component through a pressing plate.

[0008] Further, the heat dissipation column is of a regular polygon structure.

[0009] Further, multiple groups of reinforcing outer edge plates are fixedly arranged on the outer side wall of the heat dissipation column.

[0010] Further, the main heat dissipation fin is arc-shaped.

[0011] Further, the edge of the main heat dissipation fin is smooth.

[0012] Further, saw teeth are arranged on the edge of the main heat dissipation fin.

[0013] Further, reinforcing fins are connected to the surface of the fin connecting plate.

[0014] Further, round holes are formed on the surfaces of the fin connecting plate and the reinforcing fins, and screw holes corresponding to the round holes are formed on the surface of the heat dissipation column.

[0015] Further, the middle part of the heat dissipation column is hollowed out.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In this application, multiple installation cavities are arranged between adjacent groups of reinforced outer edge plates, so that multiple heat dissipation fin components can be stacked in each cavity. The heat dissipation fin components and the heat dissipation columns are designed with a dismountable assembly, which reduces the production process difficulty of the entire radiator. And according to actual usage requirements, different numbers of heat dissipation fin components can be assembled in the installation cavity to achieve different heat dissipation effects. The quick-disassembly assembly design facilitates the installation of the entire radiator. And each main heat dissipation fin is arc-shaped, increasing the space below and making heat dissipation easier. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figures 1-3 , Figures 6 - 7, the heat dissipation column 3 and the heat dissipation fin component 6, further comprising: the heat dissipation fin component 6 includes a main heat dissipation fin 66 and a fin connecting plate 67 fixedly connected to the main heat dissipation fin 66. The heat dissipation fin component 6 is connected to the heat dissipation column 3 through a pressing plate 11. Among them, corresponding round holes are opened in the pressing plate 11 and the fin connecting plate 67. A screw rod corresponding to the opening is arranged outside the heat dissipation column 3. After screwing in the screw rod, the pressing plate 11 and the fin connecting plate 67 can be fixed on the heat dissipation column 3, making the entire heat dissipation fin component 6 easier to disassemble and assemble. The disassembly and assembly design is more convenient for production and processing. Each group of main heat dissipation fins 66 is in an arc structure, and the edge of the main heat dissipation fin 66 is smooth. Both ends of each group of fin connecting plates 67 are adjacent to the main heat dissipation fin 66. Therefore, a group of heat dissipation fin components 6 is in a U shape. The heat dissipation column 3 is a regular polygon structure, at least a quadrilateral. A plurality of reinforcing outer edge plates 4 are fixedly arranged on the outer side wall of the heat dissipation column 3. There are at least 3 groups of reinforcing outer edge plates 4. An outer edge plate opening 5 is opened on the surface of each group of reinforcing outer edge plates 4. And a lamp cover part 1 for assembling and combining with the heat dissipation column 3 is arranged under the heat dissipation column 3. Among them, a reinforcing ring part 2 extending towards the center is arranged at the top of the lamp cover part 1, and a positioning hole 9 corresponding to the outer edge plate opening 5 is opened on the surface of the annular reinforcing ring part 2. The combination of the reinforcing outer edge plate 4 and the positioning hole 9 is completed through a screw rod, thereby realizing the combination of the heat dissipation column 3 and the lamp cover part 1.

[0030] A plurality of groups of heat dissipation fin components 6 can be installed on the side of the heat dissipation column 3 between two adjacent groups of reinforcing outer edge plates 4, and the heat dissipation fin components 6 can be stacked and placed. According to actual usage requirements, different numbers of heat dissipation fin components 6 can be installed in the installation cavity. The more the number of heat dissipation fin components 6, the higher the heat dissipation efficiency of the entire radiator. And because the main heat dissipation fin 66 is arc-shaped, after the heat dissipation column 3 and the lamp cover part 1 are assembled, the space between the main heat dissipation fin 66 and the outside of the lamp cover part 1 gradually increases. And due to the upward characteristic of hot air, the heat can be better dispersed, reducing heat accumulation and further improving the heat dissipation efficiency.

[0031] The fin connecting plate 67 is surface-connected to reinforce the fin 8. Round holes are opened on the surfaces of the fin connecting plate 67 and the reinforcing fin 8, and screw holes corresponding to the round holes are opened on the surface of the heat dissipation column 3. The combined cross-sectional shape of the reinforcing fin 8 and the fin connecting plate 67 is bent. When the fin connecting plate 67 is attached to the installation cavity, the reinforcing fin 8 is attached to the surface of the heat dissipation column 3. By attaching the reinforcing fin 8 to the heat dissipation column 3, the heat dissipation area can be further increased. The reinforcing fin 8 and the heat dissipation column 3 can be further reinforced by screws. A lamp body part 12 is connected to the surface of the heat dissipation column 3, and the lamp body part 12 is connected to the outer edge plate opening 5 by screws.

[0032] Embodiment 2: Please refer to Figure 4 、 5 The difference from Embodiment 1 is that sawteeth are provided on the edge of the main heat dissipation fin 66. The provided sawteeth can increase the perimeter of the main heat dissipation fin 66 and improve the heat dissipation efficiency.

[0033] Embodiment 3: Please refer to Figure 8 、 9 , and the heat dissipation column 3 is hollowed out in the middle as needed to facilitate the installation of other components.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
