SERPENTINE HEAT EXCHANGER FOR AIR CONDITIONER

PROBLEM TO BE SOLVED: To provide a serpentine heat exchanger for an air conditioner effectively suppressing deterioration of heat exchange performance caused by dew condensation, and fully coping with miniaturization of the air conditioner. SOLUTION: A fin group 14 is formed by arranging a plurality of fins 12 having a prescribed coating film layer at least on one surface of a metal plate in parallel with each other with an interval of 1.0-3.0 mm in a direction (y-direction) vertical to a flow direction (x-direction) of air as a heat exchange fluid, and plural stages of the fin groups are formed by arranging a plurality of the fin groups 14 in a line in a state they are separated from each other at a specific distance in a direction (z-direction) orthogonal to the x-direction and the y-direction, and a heat transfer tube 16 is arranged in a meandering form in such a manner of sequentially penetrating the plurality of the fin groups 14, and the serpentine heat exchanger 10 for the air conditioner is formed.
