Claims

[Scope of utility model registration request]

In a plate fin type heat exchanger comprising a large number of plate fins arranged substantially parallel to a vertical plane at intervals, and a plurality of heat transfer tubes passing through the plate fins substantially perpendicularly to the plane, the above-mentioned A heat exchanger comprising: louver fins that are cut and raised in a stepwise manner so as to protrude from the plate surface of the plate fin; and projections for adjusting the fin pitch that are protruded from the surface of the plate fin. .
