Abstract

However, for high-power luminaires, these traditional heat dissipation methods often fail to effectively dissipate heat, leading to excessively high luminaire temperatures. This, in turn, affects the luminous efficiency, color temperature stability, and lifespan of the light source, and may also pose safety hazards. Utility Model Content

The heat sink base 1 has multiple through slots 5 in its middle, all of which extend through both ends of the heat sink base 1. The first heat dissipation copper pipes 2 pass through each of the through slots 5. The top of the heat sink base 1 has multiple first arc-shaped slots 6, and the second heat dissipation copper pipes 3 are connected to the first arc-shaped slots 6. The tops of the first heat dissipation copper pipes 2 and the second heat dissipation copper pipes 3 are respectively provided with first connecting portions 7 and second connecting portions 8. Each heat dissipation fin 4 has multiple first connecting holes 9 and multiple second connecting holes 10. The heat dissipation fins 4 are arranged side-by-side from bottom to top. The first connecting portions 7 are sequentially inserted through the first connecting holes 9 from bottom to top, and the second connecting portions 8 are sequentially inserted through the second connecting holes 10 from bottom to top.
[0026] This invention utilizes a unique connection method between the first heat dissipation copper pipe 2 and the second heat dissipation copper pipe 3 and the heat sink 1, ensuring that the heat from the heat sink 1 can be quickly and evenly distributed to each heat dissipation copper pipe, achieving efficient heat transfer. The space is compactly utilized, with the heat dissipation fins 4 arranged side-by-side from bottom to top, passing through corresponding connection holes via the first connecting part 7 and the second connecting part 8. This structural design not only ensures good mechanical strength but also maximizes the heat dissipation area within a limited space, avoiding unnecessary volume expansion and facilitating miniaturization of the lamp. Each heat dissipation copper pipe is tightly connected to the heat dissipation fins 4, increasing the contact area between them and promoting effective heat transfer from the copper pipes to the fins. Furthermore, the multi-layered arrangement of the heat dissipation fins effectively increases airflow paths, promotes natural convection, further enhances heat dissipation, extends the lamp's lifespan, and improves operational reliability.
[0027] This embodiment describes a high-power lamp heat sink. The heat sink 1 includes a heat sink base 11 and a heat sink upper base 12. The top of the heat sink base 11 has a second arc-shaped groove 13 that extends through the left and right ends of the heat sink base 11. The bottom of the heat sink upper base 12 has a third arc-shaped groove 14 that extends through the left and right ends of the heat sink upper base 12. The second arc-shaped groove 13 and the third arc-shaped groove 14 together form the through groove 5. Specifically, the heat sink 1's split design, consisting of the heat sink base 11 and the heat sink upper base 12, not only simplifies the assembly and welding steps in the manufacturing process but also improves the fitting accuracy between components. Furthermore, this design facilitates subsequent maintenance work, such as replacing or cleaning the heat sink copper pipes, reducing maintenance costs and difficulty.
[0028] This embodiment describes a high-power lamp heat sink. The first heat dissipation copper pipe 2 includes a first bend 15, and both ends of the first bend 15 are provided with the first connecting portion 7. The first bend 15 passes through the through groove 5. Specifically, the design of the first bend 15 of the first heat dissipation copper pipe 2 increases its contact area with the heat dissipation fins 4, allowing heat to be transferred more effectively from the light source to the heat dissipation fins 4, thereby accelerating the heat dissipation speed and improving the efficiency of the entire heat dissipation system.
[0029] This embodiment describes a high-power lamp heat sink. The second heat dissipation copper pipe 3 includes a second bend 16, with second connecting portions 8 at both ends of the second bend 16. The bottom of the second bend 16 is connected to the first arc-shaped groove 6. Specifically, the second bend 16 and the second connecting portions 8 at both ends of the second heat dissipation copper pipe 3 ensure that heat can be evenly distributed in different areas of the heat sink, reducing the possibility of localized overheating. At the same time, the bend design also enhances the mechanical strength of the heat dissipation copper pipe and improves the stability of the overall structure.
[0030] In this embodiment, a high-power lamp heat sink is provided with notches 17 at both ends of the heat sink 1, and the two ends of the through groove 5 are respectively connected to the two notches 17.

A third heat dissipation copper pipe 19 is provided on the fourth arc-shaped groove 18, and the third heat dissipation copper pipe 19 is connected to the heat dissipation fins 4. Specifically, the fourth arc-shaped grooves 18 and the first arc-shaped grooves 6 on the top of the heat sink base 1 are arranged alternately, increasing the complexity of the heat sink surface and providing additional heat dissipation surface area.
[0032] In this embodiment of a high-power lamp heat sink, the length of the first arc-shaped groove 6 is greater than the length of the fourth arc-shaped groove 18. Specifically, the design that the first arc-shaped groove 6 is longer than the fourth arc-shaped groove 18 allows the second heat dissipation copper pipe 3 and the third heat dissipation copper pipe 19 to be staggered, thus achieving better heat dissipation.
