What is heatsink(radiator)?
Heatsink(Radiator) is an important and basic component of hot water (or steam) heating system. Hot water is cooled in the heatsink/radiator (or steam is condensed in the heatsink/radiator) and heated indoors for heating purposes.
What is extruded aluminum heatsink?
Aluminum heatsink, also known as radiator aluminum or sunflower aluminum profiles, is mainly made of high - die - cast aluminum and stretched aluminum alloys.
How does an aluminum heatsink production?
The production processing of extruded aluminum heatsink is as follow: casting --- extrusion --- aging --- oxidation/electrophoresis --- fluorocarbon spraying --- simulated grain --- insulation strip --- packing.

Aluminium heatsink(radiator) Advantages
1. Beautiful appearance, lightweight, cost-effective;
2. Good thermal conductivity, good heat dissipation performance, and good energy-saving effect;
3. Good oxidation resistance, corrosion resistance, pro-environment, and long service life;
4. Safe to use and high pressure;
5. Simple installation and easy maintenance.
How does a heatsink(radiator) works?
The working principle of the extruded aluminum heatsink/radiator is that the heat is generated and transmitted from the heating equipment to the radiator and then to the air and other substances, wherein the heat is transferred through the heat transfer in thermodynamics. And the heat transfer mode mainly includes heat conduction, heat convection and heat radiation, such as when the material and the material contact as long as there is a temperature difference, heat transfer will occur until the temperature is the same everywhere.
Product Application
The extruded aluminum heatsink are widely used in industries such as machinery, automobiles, batteries, wind power generation, construction machinery, air compressors, railway locomotives, and household appliances.
Aluminium heatsink(radiator) VS Copper heatsink heatsink(radiator)
1. The heat dissipation of aluminum is better than that of copper, but the heat conduction is slightly worse;
2. The tube in the aluminum heatsink/radiator is wider than that in the copper radiator;
3. Low cost of aluminum heatsink/radiator. The heat sink made of aluminum is very close to the heat dissipation performance of pure copper products, but the cost is far lower than that of copper;
4. Low density of aluminum, easy to process forming, good hardness, light weight.

Generally speaking, 6061 and 6063 are the most common aluminum alloys in the 6000 series, which are common for extrusion. Actually, aluminum alloy is quiet well for heatsink/radiator, therefore, which aluminum alloy suitable for your heatsink(radiator) is base on your demands.
Formula for calculating thermal resistance of extruded aluminum heatsink
Calculation formula: Rzo(total thermal resistance)= Rth(solid heat transfer in the radiator)+ Rthk(heat transfer resistance between the radiator and air)
Ks is the thermal conductivity of the metal material of the radiator. At 20℃, pure aluminum: KS=175.6 kcal/h m ℃;
Us indicates the wind speed m/s of the radiator.
