What Are Extruded Aluminum Fin Tubes?
Extruded aluminum fin tubes are specialized heat transfer elements used in finned tube heat exchangers. These components feature aluminum fins extruded directly from an aluminum tube, while the core tube can be manufactured from various materials to suit specific application requirements.
This innovative design combines aluminums exceptional thermal conductivity with the structural integrity of various base tube materials, resulting in superior heat transfer efficiency and long-term reliability.
The extruded fins form a continuous, integral structure along the tube length, ensuring optimal thermal contact and eliminating the risk of fin separation under thermal cycling conditions.
How Are Extruded Aluminum Fin Tubes Fabricated?
The extrusion process transforms aluminum into highly efficient heat transfer surfaces through precise engineering:
1
Material Preparation
An aluminum sleeve is precisely fitted over the base tube material (copper, stainless steel, carbon steel, etc.)
2
Die Design & Setup
A specially engineered die is prepared to create the desired fin geometry, thickness, and configuration
3
Extrusion Process
High pressure forces the aluminum through the die, forming continuous fins directly from the tube surface
4
Bond Formation
The extrusion pressure creates a permanent mechanical bond between the fins and the base tube
5
Cooling & Finishing
The finned tube is cooled, inspected, and cut to precise lengths for specific applications
6
Quality Assurance
Each tube undergoes rigorous testing for bond integrity, dimensional accuracy, and thermal performance
Base Tube Material Options
