Claims

[Scope of utility model registration request]

For a heat exchanger, the heat exchanger is constituted by a flat metal hollow extruded material 2 having a fluid passage 3, and a large number of convex portions 5 are formed on the inner surface of the extruded material 2 by pushing and deforming a wall 4 from the outside of the extruded material 2. tube.
