Abstract:
1. A side-flow type parallel-flow heat exchanger, comprising: a plurality of header pipes arranged in parallel with one another at intervals; a plurality of horizontal fiat tubes disposed between the plurality of header pipes and each having a horizontal refrigerant passage formed therein in communication with insides of the header pipes; and corrugated fins disposed between the plurality of flat tubes, wherein edges of the corrugated fins located close to a face of the heat exchanger on a side where condensate water collects are formed as protruding portions that protrude from edges of the plurality of fiat tubes; linear water guide members are situated into gaps between the protruding portions to a depth within a range that surface tension of the condensate water on the protruding portions is exerted on the linear water guide members; and each of the water guide members comprises a single flat member formed of a water-absorbent member, extends deep enough to reach one of the plurality of flat tubes, and is situated at a point that the water guide member is in contact with an edge of the one of the plurality of flat tubes extending between adjacent corrugated fins, the edge of the flat tube is parallel to the refrigerant passage, and wherein the water guide members are in contact with the edges of the corrugated fins and protrude from the edges of the corrugated fins.
