Air cooled Heat Exchangers (or) Fin fan Cooler or Air Fin Cooler are the same Air Cooling equipment. In some part of the world Air Cooled Heat Exchangers are also known as Air Fin Cooler. Simply says Air Fin cooler, Fin Fan cooler, Coil Cooler, Dry Cooling Tower are the other names of Air Cooled Heat Exchangers. It also used for Heat rejecting from a hot process fluid to the surrounding atmosphere by using the atmospheric air as a cooling media. The Air Fin Coolers are basically designed with multiple rows of finned tubes in a series of surface and required numbers of fans are used to move the low temperature atmospheric ambient air over the finned tube coil surface in order to cool the hotter fluid media. It is nothing but an extended type of industrial or automotive radiators. The finned tube bundles are modular construction for easy transportation. The various types of headers are Welded Bonnet Header, Plug Header, Manifold header, Plug and pipe header etc., The various types of Fins are 'L' type Wrap-On Fins, 'G' type Embedded Fins and Bi-metallic Extruded Fins etc., . In some small type heat Exchanger wire strip type copper wounded knurled Fins are also used. Other than finned tube bundle and headers, Axial flow fans and drives etc are used as per the Cooler requirement.
