Aluminium Finned Tube

  • Aluminum finned tube refers to a kind of heat exchange device. To improve the heat exchange efficiency, fins are usually added to the surface of the core tube to increase the outer surface area (or inner surface area).
  • The aluminium finned tube is a new, wear-resistant and efficient heat exchange material. It is a high-efficiency and energy-saving heat exchange element, which has the characteristics of high heat exchange efficiency, large heat dissipation area, long service life, wide temperature range and high-pressure adaption.
  • CHAL provides a full range of finned tubes for heat exchangers with reliable quality, high performance, complete designs and competitive price.

Aluminum Finned Tube

The Features of Aluminium Finned Tube

1. Good Corrosion Resistance

Under serious conditions, the oxide materials from aluminum are non-toxic. For heat exchange, no need to worry that air or liquid inside will be destructed by oxide even for a long time.

2. Low Density

By treatment as alloying or heat, it can be used as the structure of construction steel. Feasible for various transportation, especially for small vehicles to reduce weight and consumption.

3. High Yielding and resistance to die-cutting.

It is easy to process and form.

4. Good Thermal Conductivity

Especially compatible for radiating fin, heat transfer condenser and evaporator.

Advantages of Aluminium Finned Tube

1. Finned tube has compact structure, easy and economical to install. It reduces the joints compared to bare tube, making installation more quickly and cost-saving, reducing the possibility of water leaking at the connection.  
Simple for maintenance, you basically don’t need to maintain finned tubes after installation.

2. High efficiency, the finned tube is in full contact with the fin and aluminium pipe, the heat dissipation area is more than 7-8 times that of the bare tube, the inside is smoother, and the internal water flow resistance is small.

3. Long service life, the high mechanical strength of the combination of fins and pipes. The tensile strength is above 200Mpa.

4. Stable heat transfer performance. It has few temperature fluctuations, reduces the high-temperature corrosion and over-temperature damage of the metal surface.

5. Widely adaptable for heat exchange between air-air, air-liquid, liquid-liquid and various fluids.

Why Use Aluminium Finned Tube?  

Based on the heat exchange application, there are many kinds of materials, and which are Aluminum, Alloy, Copper, Brass, Stainless Steel, Titanium, Carbon Steel, Nickel, etc, while among them, the prominent one is aluminum, and it’s being commonly used.

The fundamental uses of finned tube heat exchange should be with good solderability and better mechanical strength, formability, good corrosion resistance and thermal conductivity. Aside from these, aluminum and alloy also have good advantages as in extension and higher tensile strength increases under lower temperature. All around the world, especially for places where are always at low temperature and compact heat exchange, aluminium finned tubes are widely applied.
