Finbraze® Finned Tubing

What Are Finbraze® Finned Tubes?

Tube-Fin Heat Exchangers are another term used when referring to applied fin tubings. Simply put, it’s a tube, a different material that allows the fin to be placed or used. The fin can be of any size but is generally a thin metal. Furthermore, it will then make an annular fin in the form of a coil around the tube. In turn, it enhances the surface for more optimized cooling efficiency.

Through tension winding, soldering, brazing, or welding, a solid mechanical link is formed between the tubes. You can combine two contrasting materials to benefit from both. However, comparable metals are utilized in more prevalent applications. However, it is dependent on the application and uses.

Remember that each of the materials used has its own advantages and considerations. But it largely depends on end use and its overall effect on performance and efficiency. An aluminum fin and a stainless steel tube can help improve and maximize cooling efficiency in the cooling industry.

On the other hand, copper fins provide excellent heat transfer. However, it’s more susceptible to corrosion. Stainless steel offers much lower heat transfer. At the same time, it’s not vulnerable to corrosion, unlike copper. Overall, using applied fin tubing offers excellent advantages if used correctly.

Advantages of an applied fin tubing

  • You may use different materials to improve its cooling efficiency.
  • The fin material can be the same or different from the tube material.
  • It provides a more balanced thermal conductance on the two sides of the heat exchanger, allowing for a heat exchanger of the smallest possible size.
  • The finned tube provides high thermal efficiency in a small space.
  • The finned-tube heat exchanger has a large surface area in a small volume, which results in quick heat transfer.
  • You may use an applied fin tubing for various applications in different industries.
