Claims

[Scope of utility model registration request]

A thermal heat treatment system in which a large number of tube insertion holes are bored and a large number of plate fins each having a large number of cut and raised protrusions are stacked on top of each other at equal intervals at a predetermined fin pitch, and a tube is fitted into each tube insertion hole. In the exchanger, the cut and raised projections of the plate fins have the same height as the fin pitches, and when the plate fins are arranged in an overlapping manner, the cut and raised projections of the plate fins have opposite ends. A heat exchanger characterized by having a shape that does not fit into the root hole of the heat exchanger.
