What is a Heatsink (radiator)?

Heatsink (radiator) is an important basic component of a hot water (or steam) heating system. Hot water is cooled in a radiator/radiator (or steam is condensed in a radiator/radiator) and heated in the room for heating purposes.

What is an extruded aluminum heatsink?

Aluminum heatsink, also known as radiator aluminum or sunflower aluminum profiles, are made primarily from high-pressure cast aluminum and tensile aluminum alloys.

How are aluminum heatsink produced?

The production process of extruded aluminum radiator is as follows: casting – extrusion – aging – oxidizing/electrophoresis – Fluorocarbon spraying – Texture imitation – Insulation strip – Packaging.

Aluminum Radiator (Radiator) Advantages

1, beautiful appearance, lightweight, cost-effective;

2, good thermal conductivity, good heat dissipation performance, energy saving effect;

3, good oxidation and corrosion resistance, environmental protection, long service life;

4, the use of safety, high pressure;

5, simple installation, easy maintenance.

How does the heatsink work?

Extruded aluminum radiators/radiators work on the principle that heat is generated and transferred from the heating equipment to the radiator and then to the air and other substances, where heat is transferred by heat transfer in thermodynamics. And heat transfer mainly includes heat conduction, heat convection and heat radiation, for example, when a material is in contact with a material as long as there is a temperature difference, heat transfer will occur until the temperature is the same everywhere.

Product application

Extruded aluminum heatsink is widely used in machinery, automobile, battery, wind power generation, engineering machinery, air compressor, railroad locomotive, household appliances and other industries.

Aluminum heatsink VS copper radiator ink radiator (radiator)

1. Aluminum dissipates heat better than copper, but conducts heat slightly worse;
2. the tubes in an aluminum radiator/radiator are wider than those in a copper radiator;
3. aluminum radiators/radiators cost less. Radiators made of aluminum are very close to the thermal performance of pure copper products, but cost much less than copper;
4. the low density of aluminum makes it easy to machine and shape, hard and light.

Which aluminum alloy is suitable for your radiator (radiator)?

Generally speaking, 6061 and 6063 are the most common aluminum alloys in the 6000 series and are commonly used for extrusion. Aluminum alloys are actually quiet for radiators/radiators, so which aluminum alloy is right for your radiator/radiator depends on your needs.

Extruded Aluminum Radiator Thermal Resistance Calculation
Formula Calculation formula: Rzo (total thermal resistance) = Rth (heat transfer from solids in the radiator) + Rthk (resistance to heat transfer between the radiator and air)
Ks is the thermal conductivity of the metal material radiator. At 20°C, pure aluminum: KS = 175.6 kcal/hm ℃;
