Abstract

Abstract An air conditioner accommodates therein a heat exchanger (5) having a plurality of plate fins (11) and a plurality of heat exchanging pipes (9), and a once-through fan (10) located rearwardly of the heat exchanger. A V-shaped cut-out (14) is provided only in one side of the plate fin toward the blower. An upper portion of the plate fin above the cut-out (14) and a lower portion of the plate fin below the cut-out are bent substantially into an L-shaped configuration at a predetermined angle to form the heat exchanger (5). A bent portion (6) on the heat exchanger (5) is positioned in the vicinity of a level of a center of rotary axis of the once-through fan (10).
