Claims

[Scope of utility model registration request]

(1) In a finned tube type heat exchange pipe in which a large number of fins are inserted into a heat exchange pipe with narrow gaps between them, the fins are curved in an arc shape along a direction perpendicular to the longitudinal direction. An air heat exchanger characterized in that both curved edges protrude from the end face of the insertion part of the exchange pipe.

(2) The above-mentioned fin has a plurality of slit fins that protrude along the longitudinal direction and are arranged in parallel at a predetermined interval in a direction perpendicular to the longitudinal direction, and the protruding end surfaces of these slit fins are perpendicular to the longitudinal direction. The air heat exchanger according to claim 1, wherein the slit fins are curved in an arc shape in a direction opposite to the projecting end surface. .
