Abstract (en)
A heat exchanger includes a first fin, a second fin, a first heat transfer tube positioned away from an upstream end of the first fin by a first predetermined interval and passing through the first fin, and a second heat transfer tube positioned away from an upstream end of the second fin by a second predetermined interval and passing through the second fin. When the first heat transfer tube and the second heat transfer tube are viewed in such a manner that a lower surface of the first heat transfer tube is horizontal, in a vertical cross section perpendicular to a direction in which the first heat transfer tube passes through the first fin, upper surfaces of the first and second heat transfer tubes are inclined downward toward the upstream ends of the first and second fins, respectively, an upper end of the second heat transfer tube is located higher than the lower surface of the first heat transfer tube, and an intersecting point A at which an extension line of the upper surface of the second heat transfer tube and an extension line of the lower surface of the first heat transfer tube intersect is located closer to the second heat transfer tube than is an intersecting point B at which the extension line of the upper surface of the second heat transfer tube and an extension line of the lower surface of the second heat transfer tube intersect.
