Finned Tube heat Exchanger



In a finned tube heat exchanger, fins are outside the tubes. The liquid will flow through the finned tube with air or another gas flowing outside, increasing the heat transfer rate due to the greater heat transfer surface area.

The fins on a crossflow tube exchanger are usually circular or square radial fins. Fins should be longitudinal rather than radial in a counterflow or can be parallel flow fin tube exchangers. In an enclosed heat exchanger, finned tubes work as internal tubes.

Finned tube heat exchangers are helpful in the chemical industry, petrochemical industry, automobile (heavy truck radiators, car radiators) industry, etc.
