Introduction

Heat exchange is important in energy systems for many applications in a number of industries. That is why, engineers are always in search of the advanced components to use for heat exchanger.

An Aluminum Extruded Finen Tubetube is THE ONE STOP, ZERO WORSKTATION solution for increasing the low thermal nature. In addition, it has good corrosion resistance and long service life.

While we compare aluminum extruded fin tube with conventional welded fin tubes, the mechanical extrusion technology is used in aluminium extruded fin tube. Accordingly, they develop a working bond between aluminum fins and inner tubing.

Most commonly used in air cooled heat exchangers, HVAC systems, petrochemical equipment and industrial cooling systems due the benefits of lightweight designs combined with high efficiency aluminum extruded fin tubes.

Defining Aluminum Extruded Fin Tube

Aluminum Extruded Fin Tube — A heat transfer tube with aluminum as its external fin material

An aluminum sleeve wraps over the base tube in production.

Thereafter, mechanical extrusion apparatus can use high pressure.

The direct consequence is that the aluminum sleeve makes continuous fins around the inner tube.

The final structure contains:

• Aluminum external fins
• Steel, Copper or Stainless steel Inner Tube
• Strong mechanical bonding area

Thus, the extruded fins tubes made of aluminum offer a very high level of thermal conductivity.

Les matériaux couramment utilisés pour les tubes de base sont notamment :

• Acier au carbone
• Acier inoxydable
• Cuivre
• Titane

The inner tube is further protected with an added layer of aluminum which improved the corrosion resistance.

Tube à ailettes extrudées

What are Aluminum Extruded Fin Tubes?

Increase in external surface area which improves the heat transfer to ambient by Aluminum extruded fin tubes.

Step 1 — Hot or cold fluid flows through the inner tube.

Subsequently, thermal energy transfers inside the tube wall.

Next, tail aluminum fins distribute warmth into the encompassing air.

At the same time, airflow goes through expanded fin surface.

Consequently, heat exchange efficiency increases.

Thermal resistance is low since aluminum fins remain very close to the tube.

En conséquence, aluminum extruded fin tubes are operationally stable and practical.

Manufacturing of aluminum extruded fin tube

It has a reliable performance because of its professional manufacturing process.

4.1 Préparation du tube de base

Manufacturers select suitable inner tubes.

The selection depends on:

• Operating temperature
• Pressure requirements
• Fluid characteristics
• Corrosion conditions

Manufacturers clean and inspect the surface of the tube.

4.2 Montage du manchon en aluminium

The base tube is dressed with a seamless aluminum sheath.

The thickness of the sleeve is based on the design fin height and application needed.

4.3 Extrusion mécanique

The extrusion machine exerts enormous force outward around the aluminum sleeve.

As a result, the aluminum figurates and makes fins.

During the same time, aluminum presses tightly up into the base tube.

Thus, high thermal contact is being made in this tube.

4.4 Formage des ailettes

Le procédé d'extrusion permet d'obtenir :

• Hauteur uniforme des ailettes
• Stable fin spacing
• Continuous fin structure

This ensures even heat transfer performance through the thickness of the tube.

4.5 Contrôle qualité

Les fabricants vérifient :

• Dimensions des ailettes
• Rectitude du tube
• Qualité de surface
• Résistance d'adhérence

Therefore, customers receive reliable products.

Top Benefits of Aluminum Extruded Fin Tubes

Benefits associated with those aluminium extruded fin tubes.

5.1 Excellente résistance à la corrosion

Aluminum automatically creates an oxide layer that protects the metal.

As a result, it protects the inner tube from outside damage.

Additionally, it strengthens outdoor durability.

Thus, it is the reason aluminum extruded fin tubes work excellently in limited conditions.

5.2 Rendement élevé en matière de transfert thermique

Aluminum offers good thermal conductivity.

That is why the heat dissipates quickly when aluminum fins.

In addition, the large fin area enhances heat transfer on the air side.

Consequently, equipment attains improved thermal performance.

5.3 Strong Fin-to-Tube Bond

A mechanical extrusion provides a very close bond.

As a result, fins are stable in operation.

In addition, the construction is vibration and heat resistant.

Consequently, equipment reliability improves.

5.4 Lightweight Structure

Aluminum has a low density.

C'est pourquoi, le aluminum extruded fin tubes help in weight enhancement of equipment.

This also facilitates transportation and installation.

5.5 Longue durée de vie

Corrosion risks are mitigated by the aluminum protective coating.

Therefore, maintenance frequency decreases.

This, in turn, results in lower operating costs for companies.

5.6 Excellent Outdoor Performance

There are many challenges to outdoor heat exchangers.

Par exemple :

• Pluie
• Humidité
• Salt atmosphere
• Variations de température

These conditions are efficiently fulfiled by aluminum extruded fin tubes.

Hence most of them are utilized in the outdoor heat exchanger systems.

5.7 Combinaison de matériaux souples

Aluminum fins can be combined with other tube materials by manufacturers.

En voici quelques exemples :

• Aluminum + carbon steel tube
• Aluminium + tube en acier inoxydable
• Tube en aluminium et cuivre

So they may choose appropriate solutions for different purposes.

Materials and Structure of aluminum Extruded Fin Tube

Les aluminum extruded fin tube generally consists of two primary components.

Aluminum Fin Layer

The aluminum layer provides:

• Protection contre la corrosion
• Heat transfer surface
• Structure légère

Inner Tube

The working fluid is in the inner tube.

Parmi les matériaux couramment utilisés, on trouve :

Carbon Steel Tube

Allie résistance et rentabilité.

Stainless Steel Tube

Offers excellent corrosion resistance.

Copper Tube

Provides superior thermal conductivity.

Material selection is, therefore, dictated by application requirements.
