Claims

[Scope of utility model registration request]

It consists of an outer circumferential wall that forms an internal space, and a corrugated partition wall that partitions the internal space into a large number of fluid passages via folded sections that are continuous with the outer circumferential wall. The partition wall is formed by bending a series of metal sheets having a metal layer for brazing on one side, and heat treatment causes the inner surface of the outer peripheral wall and the corrugated partition wall to connect through the metal layer for brazing. A heat exchanger tube characterized in that the protruding parts of the parts are brazed.
