Abstract (en)
Disclosed is a heat exchanger having a corrugated fin (5) on which a plurality of louvers (12, 14) are arranged in an air-flow direction (D), wherein a length A in the air-flow direction (D) of each of a windward flat portion (11) and a leeward flat portion (15) is set in a range of 0.5 mm to 1.1 mm, a length B of an intermediate flat portion (13) is set in a range of 0.5 mm to 1.7 mm, an inclination angle of each of the windward louvers (12) and the leeward louvers (14) is set in a range of 23 degrees to 26 degrees, and a length of a chord (5b) of a circular arc portion forming a turning part (5a) of the corrugated fin (5) is set at a length of 1.2 mm or more. By optimizing all of these factors, the efficiency for heat exchange of the heat exchanger may be greatly improved.
