Frequently Asked Questions About Fin Tube Coil

December 02, 2022

1. What are Fin Tube coils?

What do they do? Finned Tube Coil transfer heat energy from a steam or liquid (inside the tubes) into air (across the fins) or vice versa. We produce Finned Tube Coils from one off small applications to much larger commercial and industrial projects. The list of applications are endless!

Fin Tube

2. What is the role of the fins on the finned tube coil?

The fins on the coil serve two main functions: they straighten the air as it comes in contact with the intake side of the coil, and they do some heat transfer. Learn the fundamentals of finned tube coils and maximize coil capacity and efficiency.

3. What is the main heat transfer surface of the finned coil?

In a finned tube coil, the tubes are the primary heat transfer surfaces and the fins are the secondary heat transfer surfaces. It's important to have good metal contact between the fins and the tubes, because without it there's no thermal path for heat to move. The temperature difference between two media.

4. Why do HVAC coils use Finned Copper Tubes and Aluminum Fin Tubes?

Copper is great at transferring heat, while aluminum, while still very efficient, is not as good. The primary goal of any HVAC coil is to cool or heat. Heat transfer is always a top consideration. Cost is second. Copper works great for tubes, but can be prohibitive for heat sinks. You need a compelling reason for the heatsink to be copper, and sometimes there are reasons to. However, the vast majority of HVAC coils you see are made with copper tubing and aluminum fins. This combination provides the most efficient heat transfer at the most effective cost. First off, the fins are responsible for an amazing 65% - 70% of the heat transfer on any coil, while the tubes are responsible for the remaining 30% - 35%. Also, in order for your coil to work at its peak performance, you need to have an excellent fin/tube combination. The fins are called secondary surfaces and the tubes are called primary surfaces. Although it might seem counterintuitive, the secondary surface transfers twice as much heat as the primary surface.
