The finning is achieved by extruding the fin from the tube.This method of construction is very different from cutting grooves onto the tube as is often done by people who are on the lookout for a shortcut or who don't know any better.A High fin tube is formed by passing a tube through a set of rollers that form the fins from the parent material of the tube by making it flow in the desired way.High finned tubes basically consist of a metal tube, surrounded by an aluminum strip or sometimes copper strip. This strip can be applied in different ways. A distinction is made, among others, between a type L, a type KL, a type LL, a type 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 can be made of different types of metal, depending on the intended application of the high finned tubes. Within a heat exchanger, the hot medium runs through the finned tubes and heats the tube and the aluminium fins. The metal tube heats up, after which it transfers its heat to the aluminum fins. These fins then ensure that the heat is transferred into the ambient air.
