DRAIN STRUCTURE FOR CORRUGATED TYPE HEAT EXCHANGER

PROBLEM TO BE SOLVED: To improve inducibility to a drain guide of condensate by improving adhesiveness of the drain guide and fins, to reduce a contact area of the induced condensate and the drain guide, and to reduce the number of contact fins by suppressing increase of draft resistance due to installation of the drain guide, in drain structure for a corrugated fin type heat exchanger. SOLUTION: The corrugated fin type heat exchanger 1 comprises a flat tube 4 and the corrugated fins 5, and the drain guide 11 getting in touch with the corrugated fins 5 is provided in a concentrating side of the condensate. In a drain guide structure, the drain guide 11 is composed of linear members, the drain guide 11 is arranged obliquely to the flat tube 4, and at least one of both ends of the drain guide 11 is led to a lower end side or a side end side of the corrugated fin type heat exchanger 1.
