Claims

[Scope of utility model registration request]

A heat exchanger having tubes made of aluminum or aluminum alloy and corrugated fins made of aluminum or aluminum alloy that have a sacrificial corrosion effect than the tubes, the heat exchanger having a plurality of tubes parallel to each other in a pair of tanks spaced apart from each other. Both ends of the corrugate fin holding member are connected to each other, the corrugate fins are joined to the tube, and both ends of the corrugate fin pressing member are curved outward to press the outermost corrugate fin against the inner tube. In the heat exchanger that is integrally coupled to the tank, a portion of both ends of the corrugated fin pressing member extends along an extended surface of the central corrugated fin pressing portion of the pressing member to form the outermost corrugated fin end. 1. A heat exchanger characterized in that an extended holding part is formed for pressing the part.
