Fin tube heat exchangers: usually partitions, fin seal, deflector component. Between two adjacent partitions in place fin, deflector and seals form a sandwich, called channels, to such a sandwich in different ways according to the fluid superposed together, brazing as a whole will be composed of plate-beam, plate beam is board fin heat exchanger core, accompanied by the necessary head to take over, support, etc. on the formation of plate-fin heat exchanger.

Finned tube heat exchangers: a winged tube heat exchanger. Can consist of one or several root finned tubes, such as radiators, but also adding to the case, fans and other components of air-cooled type heat exchanger.

Also known as coil, is the required pieces of aluminum fins set into the tube from the cluster, with the fin and tube expander method to cluster closely with the short-U tube, head tube and the shunt circuit formed by first-class welding of heat exchangers. There are copper fin material, pipe size, there are many, usually with copper.
