Economy and Energy Saving
The high-fin tube is used to advantage when gases are to be heated
or cooled or
when a process stream is to be air-cooled. High-fin tubes come in a
wide variety of
fin heights, thickness, and spacings, giving values of Ao/Ai up to
25. For corrosion
protection, a mechanically bonded liner tube may be used inside the
finned tube.
The liner can be made of corrosion-resistant alloy, while the outer
tube and fins are
made of a high conductivity metal such as copper or aluminum to
improve heat transfer.
One major application of high-finned tubes is in air-cooled heat
exchangers. Atmospheric
air, like all low pressure gases, gives a very low heat transfer
coefficient at normal velocities.
By contrast, the tube-side fluid, usually a liquid to be sensibly
cooled or a vapor to be
condensed may have a coefficient up to 100 times higher, or even
more. Therefore, high-finned
tubes are used in these exchangers to reduce to overall size of
exchanger required.
