Abstract: A heat exchanger may include flat tubes formed of a microchannel type, and first and second fins positioned at a top and bottom of the flat tubes so as to conduct the heat of the flat tubes. The first and second fins may be respectively provided with first and second condensate water discharge fins at a top and bottom. The second condensate water discharge fins of the first fins and the first condensate water discharge fins of the second fins may come into contact, and the second condensate water discharge fins of the first fins and the first condensate water discharge fins of the second fins may be disposed in a line with respect to a vertical direction, thereby having an advantage of quickly transferring condensate water formed at the top to the bottom.

Abstract: A heat exchanger and a method of manufacturing the same are provided. With the method, a tube may be inserted into a through hole formed in at least one fin coated with a filler metal, and the tube and a fin collar of the at least one fin may be joined through the filler metal by a brazing processing. A flange may not be formed on or at a top of the at least one fin collar, which protrudes vertically from a central longitudinal plane of the at least one fin. The tube may be made of aluminum (Al), and an interval between an outer circumferential surface of the tube and an inner circumferential surface of the fin collar of the at least one fin may be approximately 0.1 mm or less. Accordingly, contact resistance occurring when fabricating a fin-tube heat exchanger using a mechanical tube expansion method may be reduced, and heat transfer performance of the heat exchanger may be improved because grooves formed within the tube may not be deformed.
