Beschreibung
Zusammenfassung:	The invention relates to a kind of fin heat exchanging tube and its producing method. It is used in the electric station air cooling condenser and the petrifaction air cooler. It is composed of a base tube (1) and a fin or a rib (2).Between the base tube and the fin filters the aluminium or aluminium alloy plating liquid with the method of hot dipping aluminium or aluminium alloy. After cooling, the base tube and the fin are jointed together. At the same time, the corrosion resistant aluminium or aluminium alloy film (3) forms on the fin surface. Compared with the current method of hot dipping zinc, the invention finds the substituting material of zinc relaxes the conflict of the zinc resource in short supply and reduces sharply the production cost of the heat exchanging component.
