Description

Technical Field

[0001] This utility model relates to the technical field of aluminum heat sink profiles, and more specifically, to an aluminum heat sink profile for high-power LED streetlights. Background Technology

[0002] Currently, high-power LED chips are commonly used as the light source in the design and manufacture of LED streetlights. These high-power LED chips generate a lot of heat during operation. To ensure that the luminaires can operate continuously and stably and provide high-quality lighting effects, they must be equipped with heat sinks with good heat dissipation performance. These heat sinks are usually made of materials with high thermal conductivity, such as aluminum alloys, and are designed with multiple heat dissipation fins to increase the heat dissipation surface area, thereby achieving rapid heat dissipation.

[0003] However, while existing heat sinks can meet the heat dissipation requirements of high-power LED chips to some extent, some problems still exist in actual use. Especially when LED streetlights suddenly generate a large amount of heat in a short period, traditional heat sinks may not be able to manage these instantaneous peak heat effectively and in a timely manner. This can cause the temperature of both the heat sink and the LED chips to rise rapidly, affecting the normal operation and lifespan of the lighting fixture. If the temperature is too high, it may even cause the LED chips to burn out or experience other malfunctions, severely impacting the lighting effect and quality.

[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 an aluminum profile for a high-power LED street light heat sink 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-power LED street light heat sink aluminum profile includes a heat sink plate with heat sink fins. The heat sink plate and heat sink fins are fixedly connected. The heat sink plate has a groove inside, and a phase change material layer is provided inside the groove. A sealing cover is detachably connected to the outside of the groove.

[0008] Furthermore, to facilitate the disassembly of the sealing cover and the replacement of the phase change material layer, the sealing cover is provided with an installation block, and the heat sink is provided with an installation groove. The installation block matches the installation groove, and the installation block is provided with a circular groove. A telescopic spring is provided inside the circular groove, and one end of the telescopic spring is connected to the locking post.

[0009] Furthermore, the heat sink is equipped with slots, and the slots are matched with the pins.

[0010] Furthermore, the number of mounting blocks is two.

[0011] Furthermore, there are multiple heat dissipation fins.

[0012] Furthermore, to ensure the sealing of the groove and prevent dust and moisture in the air from entering the groove, a sealing gasket is fixedly connected to the inside of the sealing cover, and the sealing gasket matches the groove.

[0013] Furthermore, in order to enhance the management of instantaneous peak heat while ensuring the heat dissipation performance of the radiator, the phase change material layer is composed of graphite-reinforced paraffin.

[0014] The beneficial effects of the utility model are:

[0015] (1) By setting graphite-reinforced paraffin as a phase change material layer in the grooves inside the heat sink, a large amount of latent heat can be absorbed and released during the phase change process. This design helps to quickly absorb instantaneous peak heat and maintain the operating temperature of the lamp within a stable and safe range, thereby extending the service life of the LED street light.

[0016] (2) By setting a sealing cover and using the cooperation of the mounting block, the telescopic spring in the circular groove and the locking pin and the slot to achieve a stable lock on the sealing cover, it can prevent the phase change material from leaking during the phase change process. At the same time, this detachable design makes the replacement of the phase change material simple and quick, reducing maintenance costs and time. Attached Figure Description

[0024] 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.

[0025] According to an embodiment of the present invention, an aluminum profile for a high-power LED street light heat sink is provided.

[0026] Example 1

[0027] like Figures 1-4As shown, the high-power LED street light heat sink aluminum profile according to an embodiment of this utility model includes a heat sink 1, on which heat sink fins 2 are provided. The number of heat sink fins 2 is multiple, increasing the heat dissipation area, improving natural convection, helping to distribute heat more evenly, and enhancing overall heat dissipation efficiency. The heat sink 1 and heat sink fins 2 are fixedly connected. A groove 3 is provided inside the heat sink 1, and a phase change material layer 4 is provided inside the groove 3. The phase change material layer 4 is wrapped inside a flexible sealing bag, which further prevents leakage of the phase change material layer 4 during the phase change process and prevents the phase change material from adhering to the inside of the groove 3. The phase change material layer 4 is composed of graphite-reinforced paraffin, a composite material made by adding graphite powder to molten paraffin. The high thermal conductivity of graphite significantly improves the overall thermal conductivity of the composite material, enabling faster heat transfer from the heat source to the interior of the phase change material, accelerating the phase change process, and allowing the system to respond more quickly to temperature changes. A sealing cap 5 is detachably connected to the outside of the groove 3. Through the above scheme, when the LED street light generates a large amount of heat during operation, this heat is transferred to the phase change material layer 4 inside the heat sink 1. Graphite-reinforced paraffin, as a phase change material, has a high latent heat of phase change, meaning that it can absorb and release a large amount of heat during the phase change process. When the temperature rises to the melting point of the paraffin, it changes from solid to liquid, absorbing a large amount of latent heat, thus effectively reducing the temperature of the heat sink 1. Conversely, when the temperature drops, the liquid paraffin re-solidifies, releasing the previously absorbed latent heat, thereby maintaining the temperature of the heat sink 1 within a relatively stable range. This allows for rapid absorption of instantaneous peak heat, preventing a sharp rise in the temperature of the heat sink 1 and the LED chips.

[0028] like Figures 1-4 As shown, two mounting blocks 6 are fixedly connected to the inner side of the sealing cover 5. The heat sink 1 has a mounting groove 7, and the mounting blocks 6 match the mounting groove 7. A circular groove 8 is provided on the mounting block 6, and a telescopic spring 9 is installed inside the circular groove 8. One end of the telescopic spring 9 is connected to a locking post 10. A locking groove 11 is provided on the heat sink 1, and the locking post 10 matches the locking groove 11. A sealing gasket 12 is fixedly connected to the inner side of the sealing cover 5, and the sealing gasket 12 matches the groove 3. With this solution, when the phase change material layer 4 needs to be replaced, the locking post 10 can be pressed to retract into the circular groove, and then the sealing cover 5 can be removed by pulling it outwards, allowing the phase change material layer 4 inside the groove 3 to be taken out. After replacing the new phase change material layer 4, the mounting blocks 6 can be placed inside the mounting groove 7, and under the action of the telescopic spring 9, the locking post 10 will be placed in the locking groove 11, thus fixing the sealing cover 5.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting graphite-reinforced paraffin as a phase change material layer 4 in the groove 3 inside the heat sink 1, a large amount of latent heat can be absorbed and released during the phase change process. This design helps to quickly absorb instantaneous peak heat, maintain the operating temperature of the lamp within a stable and safe range, thereby extending the service life of the LED street light. Furthermore, by setting a sealing cover 5, and through the cooperation of the mounting block 6, the telescopic spring 9 in the circular groove 8, and the locking post 10 with the locking groove 11, a stable locking of the sealing cover 5 can be achieved, preventing leakage of the phase change material during the phase change process. At the same time, this detachable design makes the replacement of the phase change material simple and quick, reducing maintenance costs and time.

[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.
