Claims

[Scope of utility model registration request]

In an aluminum heat exchanger, a rain hose is arranged around a core consisting of tubes, fins, and a seat plate, and each end of the rain hose is brought into contact with the seat plate and these are brazed together. At least the rain hose side tube of the core is a mating tube made of a pair of plate-shaped tube forming members, and the ends of adjacent fins are held at at least one of the air inflow and outflow side ends of each tube forming member. An aluminum heat exchanger characterized by having a protruding edge.
