<P>PROBLEM TO BE SOLVED: To provide a drainage structure of a corrugated fin type heat exchanger which structure improves drainage between heat exchanger tubes and corrugated fins and discharge rate of a large volume of water due to condensation. <P>SOLUTION: In the corrugated fin type heat exchanger, a plurality of flat heat exchanging tubes 3 parallel to each other are arranged horizontally across a pair of opposed header pipes 2a and 2b, and corrugated fins 4 are joined between the heat exchanging tubes, on the outer surfaces of lateral ends of the heat exchanging tubes, a plurality of water channels 10 are formed at proper pitches in the longitudinal direction of the heat exchanging tubes, the water channels that absorb water remaining between the heat exchanging tubes and the corrugated fins vertically adjacent thereto, and a plurality of linear water-guide members 20 are arranged horizontally at proper pitches such as to be in contact with the lateral surfaces of the vertically arranged corrugated fins to guide water downward. <P>COPYRIGHT: (C)2013,JPO&INPIT |
