Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically to a sunflower-shaped radiator with high-efficiency heat dissipation. Background Technology

[0002] With the development of high-power LED technology, its application in mining lamps is becoming increasingly widespread. Because high-power LEDs generate a large amount of heat during operation, if this heat cannot be dissipated effectively and promptly, it will lead to problems such as accelerated light decay, shortened lifespan, and performance degradation. Therefore, efficient heat dissipation design is crucial to ensuring the safe and reliable operation of high-power LED mining lamps.

[0003] Traditional sunflower-shaped heat sinks are widely used in high-power LED lighting fixtures due to their unique appearance and excellent heat dissipation. However, existing sunflower-shaped heat sinks have some manufacturing and usage defects. First, during the manufacturing process, the complex internal structure and intricate spatial construction of the sunflower shape make conventional extrusion molding inconvenient, easily generating waste and causing difficulties in demolding the finished product, increasing material costs and production difficulty. Second, while the fin design on the surface of the sunflower-shaped heat sink helps improve heat dissipation efficiency, these fins are very susceptible to deformation or damage from impacts in actual use. Once the fins are damaged, traditional designs often require replacing the entire heat sink, which not only increases maintenance costs but also wastes resources.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a sunflower-shaped radiator with high-efficiency heat dissipation to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A high-efficiency heat dissipation sunflower-shaped radiator includes a support cylinder. Multiple positioning grooves are formed on the outer surface of the support cylinder. A mounting plate is slidably installed inside the positioning grooves. One end of the mounting plate is fixedly connected to a heat dissipation fin, and one end of the heat dissipation fin is fixedly connected to a reinforcing plate. Limit grooves are formed on both sides of the positioning grooves. Anti-slip rods are fixedly connected to both sides of the mounting plate, and the anti-slip rods cooperate with the limit grooves. A protective cover is rotatably connected to one end of the positioning groove via a hinge. Both ends of the protective cover cooperate with the limit grooves. Positioning holes are formed on both sides of the protective cover and the mounting plate. Both ends of the protective cover are fixedly installed on the surface of the mounting plate by bolts.

[0008] Furthermore, in order to achieve air intake cleaning of dust on the surface of each heat sink fin, a cleaning ring is slidably installed on the outer surface of the support cylinder. A sliding groove is opened on one side of the surface of the cleaning ring, and the heat sink fins cooperate with the sliding groove. A sliding groove is opened on one side of the sliding groove, and the sliding groove cooperates with the reinforcing plate.

[0009] Furthermore, in order to reduce the resistance to airflow between the heat sink fins when performing air cooling, the surface of the reinforcing plate is provided with a drag-reducing slope.

[0010] Furthermore, to facilitate the fixed installation of the sunflower-shaped heat sink on the LED mining lamp for heat dissipation, connecting grooves are opened on each side of the inside of the support cylinder.

[0011] Furthermore, to facilitate the up-and-down movement of the cleaning ring, lifting rings are fixedly connected to both sides of the cleaning ring's surface.

[0012] Furthermore, in order to limit and block the cleaning ring, a blocking plate is fixedly connected to one end of the support cylinder.

[0013] Furthermore, in order to achieve efficient heat dissipation of the sunflower-shaped radiator, the support cylinder, mounting plate, heat dissipation fins, and reinforcing plates are all made of aluminum.

[0014] The beneficial effects of this invention are as follows: By using the mounting and dismounting plates and anti-slip plates on the heat dissipation fins, in conjunction with the positioning and limiting grooves on the surface of the support cylinder, a detachable connection between the support cylinder and each heat dissipation fin is achieved. This allows for the separate production of the support cylinder and heat dissipation fins during the manufacturing of the sunflower-shaped heat dissipation radiator, followed by assembly. This effectively reduces the manufacturing difficulty of the sunflower-shaped heat dissipation radiator and the difficulty of demolding after molding, reducing production waste. Furthermore, the detachable connection design means that when a single fin is damaged or fails, the entire heat dissipation radiator does not need to be replaced; only the damaged fin needs to be replaced. This not only reduces maintenance costs but also minimizes resource waste and improves product sustainability. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] According to an embodiment of the present invention, a sunflower-shaped radiator with high-efficiency heat dissipation is provided.

[0025] Example 1:

[0026] like Figures 1-5As shown, a high-efficiency sunflower-shaped radiator according to an embodiment of the present invention includes a hollow cylindrical support cylinder 1. The outer surface of the support cylinder 1 has multiple positioning grooves 2. A mounting plate 3 is slidably installed inside each positioning groove 2. One end of the mounting plate 3 is fixedly connected to a heat dissipation fin 4, and one end of the heat dissipation fin 4 is fixedly connected to a reinforcing plate 5. There are three reinforcing plates 5, used to increase the overall heat conduction area of ​​the radiator. The support cylinder 1, mounting plate 3, heat dissipation fin 4, and reinforcing plates 5 are all made of aluminum, which has high thermal conductivity, enabling the sunflower radiator to achieve high-efficiency heat dissipation. The positioning groove 2 has limit grooves 6 on both sides inside. Anti-slip rods 7 are fixedly connected to both sides of the loading and unloading plate 3. The anti-slip rods 7 cooperate with the limit grooves 6 to limit the horizontal sliding of the loading and unloading plate 3 after it is installed in the positioning groove 2. One end of the positioning groove 2 is connected to a protective cover 8 by a hinge. The two ends of the protective cover 8 cooperate with the limit grooves 6. The protective cover 8 and the loading and unloading plate 3 have positioning holes 9 on both sides. The two ends of the protective cover 8 are fixedly installed on the surface of the loading and unloading plate 3 by bolts to fix the loading and unloading plate 3 in the positioning groove 2 and prevent the loading and unloading plate 3 and the heat dissipation fins 4 from easily falling off after being connected to the support cylinder 1.

[0027] like Figures 1-5 As shown, a cleaning ring 10 is slidably mounted on the outer surface of the support cylinder 1. A sliding groove 11 is formed on one side of the cleaning ring 10, and the heat dissipation fins 4 cooperate with the sliding groove 11. A second sliding groove 12 is formed on one side of the sliding groove 11, and the second sliding groove 12 cooperates with the reinforcing plate 5. Lifting rings 15 are fixedly connected to both sides of the cleaning ring 10. By pulling the cleaning ring 10, it moves up and down within the sunflower-shaped radiator, allowing the cleaning ring 10 to scrape and clean the dust from the surfaces of the heat dissipation fins 4 and the reinforcing plate 5, preventing dust accumulation on the surface of the heat dissipation fins 4 after long-term use. Dust can affect heat dissipation. The surface of each reinforcing plate 5 at one end of the heat dissipation fin 4 has a drag-reducing slope 13, which is used to reduce the resistance of airflow between the heat dissipation fins 4 when the heat dissipation fins are cooled by air, so that the outside air can flow more efficiently between the heat dissipation fins 4 and the reinforcing plates 5. The support cylinder 1 has connecting grooves 14 on each side inside, which is used to facilitate the connection between the sunflower-shaped heat dissipation fin and the LED mining lamp, so as to facilitate heat dissipation. A baffle plate 16 is fixedly connected to one end of the support cylinder 1, which is used to block and support the cleaning ring 10 on the outside of the support cylinder 1, and prevent the cleaning ring 10 from falling off.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the mounting plate 3 and anti-slip plate on the heat dissipation fin 4 cooperate with the positioning groove 2 and limiting groove 6 on the surface of the support cylinder 1 to achieve a detachable connection between the support cylinder 1 and each heat dissipation fin 4. After each heat dissipation fin 4 is fixedly installed on the outer surface of the support cylinder 1, the top of the positioning groove 2 is sealed by rotating the protective cover 8, and the two sides of the protective cover 8 are fixedly installed on the mounting plate 3 by bolts to achieve the complete assembly of the sunflower-shaped heat sink. After the sunflower-shaped heat sink is installed on the high-efficiency LED mining lamp, the heat generated by the LED mining lamp is transferred to the support cylinder 1 through contact. The support cylinder 1 then contacts the outside air through the surface of each heat dissipation fin 4 and the reinforcing plate 5, transferring the heat to the outside air to achieve efficient heat dissipation of the sunflower-shaped heat sink. Furthermore, due to the detachable connection design, when a single fin is damaged or fails, it is not necessary to replace the entire heat sink; only the damaged heat dissipation fin 4 needs to be replaced.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
