    摘要： A heat exchanger is provided which is capable of rapidly moving condensed water downward. The heat exchanger may include a plurality of flat tubes forming a plurality of flow paths therein; and a fin located between the plurality of flat tubes to conduct heat. The fin may include at least one first fin portion located between the plurality of flat tubes; at least one first bent portion bent at the first fin portion so as to come into contact with a first one of the plurality of flat tubes; at least one second fin portion bent at the first bent portion, the second fin portion being opposite to the first fin portion and being located between the plurality of flat tubes; a flow space defined between the first fin portion and the second fin portion; at least one second bent portion bent at the second fin portion so as to come into contact with a second one of the plurality of flat tubes; at least one condensed water discharge hole formed by cutting at least one of the first bent portion or the second bent portion; and at least one condensed water discharge fin bent at the at least one of the first bent portion or the second bent portion.
