FIN TUBE HEAT EXCHANGER, AND REFRIGERATION CYCLE APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a fin tube heat exchanger that hardly scatters condensed water stayed on a flat tube.

SOLUTION: The fin tube heat exchanger includes: plate fins 2a and 2b, a plurality of which are arranged adjacent to one another in an air flow direction and each of which are laminated with gaps in a direction perpendicular to the air flow direction; and the plurality of flat tubes 1a and 1b for working fluid passing which are inserted to the plate fins 2a and 2b in a lamination direction. A plurality of slits 3c and 3d are provided by cut and raised in the air flow direction, at parts between the flat tubes 1b of the plate fins 2b arranged downstream in the air flow direction. A trailing edge of the slit 3d provided downstream among the slits 3c and 3d is positioned upstream further than a trailing edge of the flat tube 1b.
