As already mentioned, Pushpak high during the among other, Manufacturing process things, Finned tubes are used of air, Cooled heat exchangers. High finned tubes basically consist of a metal tube, Surrounded by an aluminum strip or sometimes copper strip. This strip could function as applied in different ways. A distinction between a, Is made, Among others type l, A type kl, A a type, Type ll g = embedded or a type extruded. With extruded finning the fins are produced our of an aluminium tube instead of aluminium strip. The metal tube is capable of being created of various categories relying on, Of metal the intended utilization of the high finned tubes. Within a the hot, Heat exchanger medium runs through the finned tubes and heats the tube and the aluminium fins. The metal tube after which, Heats up it transfers its raise the temperature to the aluminum fins. These fins then confirm that the heat is transferred into the ambient air.
