摘要： A fin for a heat exchanger is joined to an outer surface of a tube, and facilitates a heat exchange between the tube and an air flowing around the tube. A sectional surface of the fin perpendicular to a flowing direction of an air has a corrugated shape that includes multiple flat portions substantially parallel to a flowing direction of the air, and a ridge portion connecting the adjacent flat portions. Multiple louvers cut in and raised from each of the flat portions at a predetermined cut-and-raised angle are disposed on the flat portion along a flowing direction of the air. A thickness of each flat portion is defined as t, a louver pitch of the louvers is defined as PL, and the thickness of each flat portion and the louver pitch satisfy a relationship of 0.035≦t/PL≦0.29.

摘要： A heat exchanger includes tubes arranged side by side, and a tank connected to ends of the tubes. The heat exchanger performs heat exchange between a first fluid flowing inside the tubes and a second fluid flowing outside the tubes. The heat exchanger includes a closing member disposed inside the tank and partially closing an opening provided at an end of a predetermined tube that is at least one of the tubes. The predetermined tube has a protrusion formed at the end of the predetermined tube. The closing member has an avoiding structure that avoids interference between the protrusion and the closing member.
