In the field of LED lighting, radiator is a key component, which is directly related to the life of LED lamp. At present, there are many kinds of radiators used in the field of LED lighting, while the self cooling radiators for industrial and mining lamps are mostly in the form of sunflower. The length and spacing of the teeth are determined by the amount of heat dissipation, and the teeth are evenly distributed along the circumference. Solar Flower radiator is recognized as a good radiator in the industry. However, due to the uniform distribution of blades, the temperature difference is basically uniform, and the effect of thermal convection and radiation is relatively poor, the heat dissipation efficiency of the radiator is difficult to achieve the best state. The aluminum base plate connected with the LED lamp and the radiator are generally connected by screws, and the connection surface can not ensure mutual tightness, so the heat transfer effect is poor.

Let me introduce its profiles as below :
Product description :
Name :Sun flower aluminium profile, LED lamp heat dissipation aluminum extrusion profile heat sink
Materials :Aluminum Alloy
Colour :Siver, Champage,Bronze,Golden,Black,Sand coating,Blue,Green
Surface treatment :Anodizing ,Powder Coating ,Electrophoresis Wood Grain,Polishing ,Brushing, Sandblasting ,ETC
Lifetime :Anodized for 12-15 years outdoor, Powder coating for 18-20 years outdoor.
Fabrication : Die designing →Die making → Smelting & alloying → QC→ Extruding→Cutting→Heat Treatment→QC→Surface treatment →QC→Packing→QC→Shipping→After Sale Service
Deep Processing :Precision cutting/CNC / Punching / Checking / Tapping / Drilling / Milling
Product advantage :
Light weight
The density of aluminum profile is only 2.7g/cm3, about one third of the density of steel and copper (7.85g/cm3 and 8.9g/cm3), which belongs to light metal. Therefore, it is used to make radiator panel, and the weight of aluminum profile is lighter under the same volume. The light aluminum profile can be used to manufacture light radiator shell in the production, which is in line with the trend of product thinning.
2. Corrosion resistance
The working environment of radiator shell is complex, and the raw materials selected must be able to pass the Customs on the anti-corrosion ability. Because of the compact oxide film formed on the surface of aluminum, it can prevent the further corrosion inside, and the aluminum profile has better corrosion resistance after surface treatment. Therefore, aluminum profiles can stand on the heel in practical application with this point, and will not affect the aesthetic and heat dissipation performance due to metal corrosion in the later period.
3. Thermal conductivity
Heat conduction and heat dissipation capability is an indispensable performance of radiator. The thermal conductivity of aluminum is 204 / w · (m · K), but the hardness of pure aluminum is low, and it is easy to deform when heated. Making pure aluminum into aluminum alloy can not only ensure excellent thermal conductivity, but also ensure long service life of radiator.
