Plate Fin Heat Exchanger

A plate and fin-type heat exchanger is constructed similarly to a plate-type exchanger but also contains fins to increase the efficiency of the system. 


Aluminium alloy is used as it gives higher heat transfer efficiency and lowers the weight of the unitPlate fin type heat exchanger

Fins can be fixed perpendicular to the direction of flow and are known as offset fins. Fins fixed in parallel to the direction of flow are straight fins.
Fins can be fixed in curvature form to increase the heat-exchanging effect and are thus known as wavy fins.
The efficiency of this heat exchanger is slightly higher than plate-type unit but installation and maintenance cost is higher.
