Pendahuluan
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.
Bahan tabung dasar yang umum digunakan antara lain:
- Baja karbon
- Baja tahan karat
- Tembaga
- Titanium
The inner tube is further protected with an added layer of aluminum which improved the corrosion resistance.
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.
Akibatnya, 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 Persiapan Tabung Dasar
Manufacturers select suitable inner tubes.
The selection depends on:
- Operating temperature
- Pressure requirements
- Fluid characteristics
- Kondisi korosi
Manufacturers clean and inspect the surface of the tube.
4.2 Pemasangan Selongsong 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 Ekstrusi Mekanis
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 Pembentukan Sirip
Proses ekstrusi menghasilkan:
- Tinggi sirip yang seragam
- Stable fin spacing
- Continuous fin structure
This ensures even heat transfer performance through the thickness of the tube.
4.5 Pemeriksaan Kualitas
Produsen memeriksa:
- Dimensi sirip
- Kekelurusan tabung
- Kualitas permukaan
- Kekuatan ikatan
Oleh karena itu, pelanggan mendapatkan produk yang dapat diandalkan.
Top Benefits of Aluminum Extruded Fin Tubes
Benefits associated with those aluminium extruded fin tubes.
5.1 Ketahanan Korosi yang Sangat Baik
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 Efisiensi Perpindahan Panas yang Tinggi
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.
Oleh karena itu, aluminum extruded fin tubes help in weight enhancement of equipment.
This also facilitates transportation and installation.
5.5 Umur Pakai yang Panjang
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.
Misalnya:
- Hujan
- Kelembapan
- Salt atmosphere
- Perubahan suhu
These conditions are efficiently fulfiled by aluminum extruded fin tubes.
Hence most of them are utilized in the outdoor heat exchanger systems.
5.7 Kombinasi Bahan yang Fleksibel
Aluminum fins can be combined with other tube materials by manufacturers.
Contohnya antara lain:
- Aluminum + carbon steel tube
- Aluminium + tabung baja tahan karat
- Aluminium + pipa tembaga
So they may choose appropriate solutions for different purposes.
Materials and Structure of aluminum Extruded Fin Tube
The aluminum extruded fin tube generally consists of two primary components.
Aluminum Fin Layer
The aluminum layer provides:
