<p>PROBLEM TO BE SOLVED: To improve heat exchange performance, prevent condensed water droplets from scattering in cooling operation, and feed air cooled enough into a room in an air conditioner by reducing a bypass flow in a heat exchanger and uniformizing wind velocity distribution. SOLUTION: A lower end section 23 is cut behind the lowest stage heat transfer tube 102 of a front line of a heat transfer fin 100 of a front surface lower portion heat exchanger section 22b such that it has a wide heat transfer area, at which lower end section there is formed an air ventilation adjusting corrugated fin S having an air ventilating resistance different from a lowered slit fine piece 200 is formed at the portion of the cut lower end section. Further, there are formed on a due reception pan 30 a front air stop rib 40 located more front than the neighborhood of the center of the front line heat transfer tube 102 and a rear portion air stop rib 41 located rear from a front end of the corrugated fin S.</p> |
