<p>PURPOSE: A heat exchanger is provided with the increased contact section between a fin and tube by a rib so that the tubes and fins are easily connected. CONSTITUTION: A heat exchanger comprises a plurality of fins(110) and a plurality of tubes(120). The fins are formed into a flat shape, and comprise through holes(111). The fins are separated each other. The fins penetrate the tubes, and comprise a plurality of refrigerant passages. A plurality of ribs(113) are formed in a part of the fins. The ribs are extended from one side of the corresponding fins. The ribs increase the contact surface with the tubes in a process of fixing the fins and tubes. The leading end of the rib is attached to one side of other fins.</p> |
