Disclosed is a heat exchanger in which a joint structure between refrigerant tubes and heat exchange fins is improved to firmly join the refrigerant tubes and the heat exchange fins. The heat exchanger comprises: the refrigerant tubes arranged to be separated from each other; headers coupled to both ends of the refrigerant tubes; and the heat exchange fins coupled to the outer surfaces of the refrigerant tubes, and arranged to be separated from each other in perpendicular direction of a direction in which the refrigerant tubes are extended. The heat exchange fins include: insertion grooves into which the refrigerant tubes are inserted; and joint plates joined to the refrigerant tubes while the refrigerant tubes are inserted into the insertion grooves. Each of the joint plates includes: a first joint part shaped to be bent from one side of the joint plate in a first direction, and joined to one surface of the refrigerant tube; and a second joint part shaped to be bent from the other side of the joint plate in a second direction opposite to the first direction, and joined to the other surface of the refrigerant tube, wherein the other side of the joint plate is opposite to the one side of the joint plate, and the other surface of the refrigerant tube is opposite to the one surface of the refrigerant tube. |
