Introduction
Thus, industries need effective heat transfer by using components.
After reviewing the different finned tube solutions, Tube à ailettes extrudées technology along with having high thermal performance also has excellent corrosion resistant property.
Tube à ailettes extrudéess are made with a solid fin enveloping the base tube that greatly increases heat transfer area. The types such as these also prove themselves effective in rigorous environments.
With industries scaling energy efficiency, the requirement for advanced fin tube solutions keeps going up.
Bangwin Thermal, we manufacture custom fin tubes and industrial heat exchanger solutions for customers around the globe.

Qu'est-ce qu'un Tube à ailettes extrudées
Un Tube à ailettes extrudées is a tube in which an outer aluminum sleeve is mechanically formed into fins surrounding a base tube.
Extruded fins, unlike welded fin tubes, form a close mechanical connection.
It makes use of pressure to expand the top aluminum outer tube on to the inner tube.
Because of this, the fin and tube make great contact.
Common structures include:
- Aluminum outer fin layer
- Steel or copper inner tube
- Integrated fin surface
Ainsi, le tube à ailettes extrudés have perfect thermal efficiency and corrosion protection.
How Tube à ailettes extrudéess Work
Fin tube is used to increase the surface area and improve its heat transfer capacity, and they are divided into three types:Tube à ailettes extrudés.
Initially, the flows of fluid are in a tube with an anchored base.
The first is heat transfer through the tube wall.
Next, aluminum fins soak and distribute heat energy.
In the meantime, air passes over the enlarged fin area.
So here heat exchanging will be faster and better.
As a result, the fins are tightly in contact with the tube surface and thermal resistance is still low.
Thus, these fin tubes guarantee reliable heat exchanger performance.
Tube à ailettes extrudées Processus de fabrication
So there are several stages of production involved.
4.1 Préparation du tube de base
The inner tube is inspected and cleaned by manufacturers.
Parmi les matériaux couramment utilisés, on trouve :
- Cuivre
- Steel
- Acier inoxydable
4.2 Montage du manchon en aluminium
The base tube is covered with a seamless aluminum tube.
Next, manufacturers set the stage for an extrusion process.
4.3 Extrusion mécanique
The aluminum sleeve is pressed by a special machine.
Thus, this aluminum has continuous fins wrapping around the tube.
4.4 Formage des ailettes
Le procédé d'extrusion permet d'obtenir :
- High fin density
- Hauteur uniforme des ailettes
- Strong tube contact
4.5 Contrôle qualité
Manufacturers check:
- Dimensions des ailettes
- Rectitude du tube
- Bond quality
- Surface finish
As a result, the final product is satisfactory enough to maintain the industry.
What are Tube à ailettes extrudées and their Main Advantages:
There are several advantages of tube à ailettes extrudés.
5.1 Excellente résistance à la corrosion
The base tube is protected by the outer aluminum layer.
Thus, the pipes are used in outdoor conditions.
Aluminum also has inherent resistance to oxidation.
Consequently, service life improves.
5.2 Superior Fin-to-Tube Bond
Mechanical extrusion ensures good contact between materials.
That way, the heat transfer from tube to fins and vice versa is efficient.
This, in turn, allows the refraining of thermal performance to remain stable.
5.3 High Heat Transfer Efficiency
A larger fin surface improves the heat exchange capacity.
This is why there will be better thermal performance of the equipment.
Furthermore, fins with their optimized designs allow more efficient airflow.
5.4 Longue durée de vie
The aluminum protection layer decreases the chances of corrosion.
Par conséquent, les besoins en maintenance diminuent.
Hence, the industries get advantage of low-operating cost.
5.5 Excellentes performances en extérieur
Outdoor heat exchangers face:
- Pluie
- Humidité
- Variations de température
- Atmospheric corrosion
Well, these conditions are handled by tube à ailettes extrudés perfectly.
Consequently, they are well-liked in air-cooled heat exchangers.
5.6 Flexible Material Combination
Different materials for tubes combined with aluminum fins are within manufacturer capabilities.
En voici quelques exemples :
- Aluminium + tube en acier
- Tube en aluminium et cuivre
- Aluminium + tube en acier inoxydable
This allows engineers to choose solutions according to application requirements.
5.7 Reduced Maintenance
Even an aluminum layer that is highly protective will reduce damage at the surface.
As a result, they require less cleaning and replacement.
