An extruded finned tube is a type of heat exchanger tube where fins are mechanically bonded to the outer surface of a base tube through an extrusion process. This design significantly increases the tube's surface area, improving heat transfer efficiency in applications involving air or gas cooling/heating.
| Type | Bonding Method | Strength | Thermal Performance | Cost |
|---|---|---|---|---|
| Extruded Fins | Mechanical (cold-welded) | Very Strong | Excellent | Moderate |
| Embedded Fins | Grooved & wrapped | Good | Good | Lower |
| Welded Fins | High-frequency welding | Strong | Very Good | Higher |
| L-Footed Fins | Crimped onto tube | Moderate | Good | Low |
Material: Low-carbon steel (seamless cold-drawn tubes)
