Finned Tube HE

Specifications :

• Originally conceived by an Italian mechanic, Paolo Fruncillo.
• A plate-fin heat exchanger is made of layers of corrugated sheets separated by flat metal plates, typically aluminium, to create a series of finned chambers.
• Separate hot and cold fluid streams flow through alternating layers of the heat exchanger and are enclosed at the edges by side bars.
• Heat is transferred from one stream through the fin interface to the separator plate and through the next set of fins into the adjacent fluid.
• The fins also serve to increase the structural integrity of the heat exchanger and allow it to withstand high pressures while providing an extended surface area for heat transfer.

Applications :

• The cost of Fin heat exchangers is generally higher than conventional heat exchangers due to a higher level of detail required during manufacture.
• However, these costs can often be outweighed by the cost saving produced by the added heat transfer.
• Fin heat exchangers are generally applied in industries where the fluids have little chances of fouling.
• The delicate design as well as the thin channels in the fin heat exchanger make cleaning difficult or impossible.
