Description
Technical Field
[0001] This utility model relates to the field of LED lighting heat sink technology, specifically to an integral chromium-nickel heat pipe heat sink for LED light heat dissipation. Background Technology
[0002] When an LED chip is working, only a small portion of the electrical energy is converted into light energy, while the majority is converted into heat energy. This causes the temperature of an LED lamp to rise rapidly after it has been working for a period of time. If left unattended, the excessively high junction temperature will directly lead to light decay, a sharp drop in luminous efficiency, and a decrease in brightness. At the same time, the electronic components and packaging materials inside the lamp will age faster, and their lifespan will be far below the theoretical value. Therefore, efficiently and reliably dissipating the heat generated by the LED into the environment is the key to ensuring the performance, lifespan, and reliability of LED lamps.
[0003] Traditional LED lights typically employ high-power power supplies, resulting in slow and uneven heat dissipation. Traditional LED heat sinks are usually made entirely of pure aluminum or aluminum alloys. Aluminum has a limited thermal conductivity (approximately 200 W / m·K), making it difficult for heat to be quickly transferred from the heat source to the distant heat sink fins in high-power-density LED applications. This leads to lower temperatures for fins farther from the heat source and uneven heat dissipation efficiency. Therefore, this solution provides an integrated bright nickel-plated heat pipe heat sink for LED lighting to address the aforementioned problems. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A bright nickel-plated heat pipe radiator for LED light heat dissipation includes a first aluminum plate and a second aluminum plate. The second aluminum plate is welded and fixed to the first aluminum plate. A heat-conducting component is disposed between the second aluminum plate and the first aluminum plate. A heat dissipation component is fixedly connected to the rear end of the heat-conducting component. The surfaces of the first aluminum plate, the second aluminum plate, the heat-conducting component, and the heat dissipation component are all integrally coated with a bright nickel layer.

[0011] Preferably, the heat dissipation assembly includes multiple heat dissipation fins, each heat dissipation fin having multiple slots, the multiple slots being respectively engaged with heat pipe one, heat pipe two, heat pipe three, heat pipe four, heat pipe five and heat pipe six; each slot has a heat-conducting ring on its upper side, the heat-conducting ring being fixedly connected to the heat dissipation fin and respectively fitted onto the surface of the corresponding heat pipe one, heat pipe two, heat pipe three, heat pipe four, heat pipe five and heat pipe six.
[0012] Compared with the prior art, this utility model proposes an integral bright nickel-plated heat pipe heat sink for LED light heat dissipation, which has the following beneficial effects:
[0013] 1. This utility model utilizes a double aluminum plate structure to rapidly absorb heat from the LED. The first aluminum plate is used to contact the heat source of the LED lamp, and multiple heat pipes welded to the aluminum plate efficiently conduct the heat to the heat dissipation fins at the rear. Solder paste is used to fill all the welding gaps between the first aluminum plate and all the heat pipes, as well as between the first and second aluminum plates, to optimize the heat transfer path. The heat-conducting ring enhances the contact efficiency and thermal conductivity between the heat pipes and the fins, allowing the heat pipes to quickly conduct heat to the heat dissipation fins. Combined with a fan installed by the customer, the heat is quickly blown away, achieving rapid heat dissipation for the LED lamp.

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0025] Reference Figure 1 As shown, an integral bright nickel-plated heat pipe heat sink for LED light heat dissipation includes a first aluminum plate 1 and a second aluminum plate 2.

[0026] Furthermore: The first aluminum plate 1 and the second aluminum plate 2 serve as the main support structure of the heat sink. They are welded together to form a sealed space. The first aluminum plate 1, as the base plate, directly contacts the LED light source and absorbs its heat. The heat is transferred to the heat dissipation component 5 through the heat conduction component 4. The heat dissipation component 5 dissipates the heat into the air, and together with the fan installed by the customer, it quickly blows away the heat, achieving rapid heat dissipation for the LED light.
[0027] Among them, the surfaces of the first aluminum plate 1, the second aluminum plate 2, the heat conduction component 4, and the heat dissipation component 5 are all plated with a bright nickel layer. The bright nickel plating covers all components to improve corrosion resistance and heat dissipation performance. At the same time, it makes the heat sink look glossy and improves its appearance.

[0029] Furthermore, the heat conduction component 4 consists of heat pipe 1 401, heat pipe 2 402, heat pipe 3 403, heat pipe 4 404, heat pipe 5 405 and heat pipe 6 406, all of which are welded to the first aluminum plate 1. Its core function is to conduct the heat absorbed by the first aluminum plate 1 to the rear heat dissipation component 5 at high speed.
[0030] Reference Figure 2-3 As shown, specifically, in this embodiment, heat pipe 1 401, heat pipe 2 402, heat pipe 3 403, heat pipe 404, heat pipe 5 405 and heat pipe 6 406 are arranged from left to right between the first aluminum plate 1 and the second aluminum plate 2; wherein, the number of heat pipe 2 402 and heat pipe 5 405 are two sets each, and the number of heat pipe 1 401, heat pipe 3 403, heat pipe 404 and heat pipe 6 406 are one set each.
[0031] Reference Figure 1 As shown, specifically in this embodiment, the welding joint between the second aluminum plate 2 and the first aluminum plate 1 is filled with solder paste 6.
[0032] Furthermore, solder paste 6 is filled at the welding joint between the first aluminum plate 1 and the second aluminum plate 2 to ensure a tight fit between the first aluminum plate 1 and the second aluminum plate 2 and reduce contact thermal resistance.
[0033] Reference Figure 1 As shown, specifically in this embodiment, the welding connections between heat pipe 1 401, heat pipe 2 402, heat pipe 3 403, heat pipe 4 404, heat pipe 5 405 and heat pipe 6 406 and the first aluminum plate 1 are all filled with solder paste 6.
[0034] Furthermore: Solder paste 6 is filled at all welding joints between the heat pipes and the first aluminum plate 1 to ensure a tight fit between the first aluminum plate 1 and all heat pipes, thereby enhancing and ensuring the heat transfer efficiency between the heat pipes and the first aluminum plate 1.
[0035] Reference Figure 1 As shown, specifically, in this embodiment, the first aluminum plate 1 and the second aluminum plate 2 have the same size and shape. The first aluminum plate 1 and the second aluminum plate 2 are coaxially connected through a positioning hole 3 in the middle, and the first aluminum plate 1 and the second aluminum plate 2 are coaxially connected through mounting holes 7 at their four corners.
[0036] Furthermore: the positioning hole 3 is opened in the middle of the first aluminum plate 1 and the second aluminum plate 2, and is used to accurately position the heat sink on the lamp during assembly. The mounting hole 7 is opened at the four corners of the two aluminum plates to provide mechanical fixing points, so as to facilitate the overall installation of the heat sink onto the lamp structure.
[0037] Reference Figure 3-4 As shown, specifically in this embodiment, the heat dissipation assembly 5 includes multiple heat dissipation fins 501. Each heat dissipation fin 501 has multiple slots 502, which are respectively engaged with heat pipe 1 401, heat pipe 2 402, heat pipe 3 403, heat pipe 404, heat pipe 5 405, and heat pipe 6 406. Each slot 502 has a heat-conducting ring 503 on its upper side. The heat-conducting ring 503 is fixedly connected to the heat dissipation fin 501 and is respectively sleeved on the surface of the corresponding heat pipe 1 401, heat pipe 2 402, heat pipe 3 403, heat pipe 404, heat pipe 5 405, and heat pipe 6 406.
[0038] Furthermore: It consists of multiple heat dissipation fins 501, which are snapped into all heat pipes through slots 502. A heat-conducting ring 503 is fixed on the heat dissipation fins 501 and sleeved with the heat pipes to enhance the heat transfer between the heat pipes and fins. By increasing the contact area between the heat pipes and fins, the heat conduction rate from the heat pipes to the fins is improved.
[0039] The working principle of this utility model is as follows: the heat sink is precisely positioned on the lamp by the positioning hole 3 opened in the middle of the first aluminum plate 1 and the second aluminum plate 2, and then the mounting holes 7 opened at the four corners of the two aluminum plates provide mechanical fixing points to install the heat sink as a whole onto the lamp structure.
[0040] When the LED lamp is working, it generates a lot of heat. The first aluminum plate 1, as the base plate, directly contacts the LED light source and absorbs its heat. Subsequently, heat pipes 1-401, 2-402, 3-403, 4-404, 5-405 and 6-406, which are welded to the first aluminum plate, conduct the heat absorbed by the first aluminum plate 1 to the rear heat dissipation component 5 at high speed.
[0041] The heat dissipation component 5 consists of multiple heat dissipation fins 501, which are connected to all heat pipes via slots 502. The heat-conducting ring 503 is fixed on the heat dissipation fins 501 and sleeved with the heat pipes to enhance the heat transfer between the heat pipes and the fins. By increasing the contact area between the heat pipes and the fins, the heat transferred from the heat pipes is quickly transferred to the heat dissipation fins 501. Together with the fan installed by the customer, the heat is quickly blown away, achieving rapid heat dissipation for the LED lights.
[0042] Among them, the surfaces of the first aluminum plate 1, the second aluminum plate 2, the heat conduction component 4, and the heat dissipation component 5 are all plated with a bright nickel layer. The bright nickel plating covers all components to improve corrosion resistance and heat dissipation performance. At the same time, it makes the heat sink look glossy and improves its appearance.
