<p>A heat exchanger is configured so that the fins and the heat transfer pipes are made to contact with each other without problem while the function of conducting condensate water is ensured. First fin sections (51) and second fin sections (52), the first and second fin sections (51, 52) constituting fins (50a, 50b), are arranged so that the plate thickness direction thereof intersect the air current direction (F) and so that the first fin sections (51) and the second fin sections (52) are adjacent to each other. Each of the first fin sections (51) and each of the second fin sections (52) respectively have heat transfer sections (51a, 52a), upward water conduction sections (51b, 52b) which protrude upward from the heat transfer sections (51a, 52a), and downward water conduction sections (51c, 52c) which protrude downward from the heart transfer sections (51a, 52a). The amount of protrusion of the upward water conduction sections (51b) of the first fin sections (51) is different from the amount of protrusion of the upward water conduction sections (52b) of the second fin sections (52) but the same as the amount of protrusion of the lower water conduction sections (52c). The amount of protrusion of the downward water conduction sections (51c) of the first fin sections (51) is different from the amount of protrusion of the downward water conduction sections (52c) of the second fin sections (52) but the same as the amount of protrusion of the upward water conduction sections (52b).</p> |
