PROBLEM TO BE SOLVED: To provide an air-cooled heat exchanger for an aircraft capable of surely preventing end part damage of a corrugated fin in an air circulation passage on an exposure end surface on both ends in an air circulation direction, while suppressing the deterioration of heat exchange efficiency, without involving increase in the number of components and increase in manufacturing cost.SOLUTION: The air-cooled heat exchanger for an aircraft comprises a crossflow plate fin type heat exchanger in which a corrugated fin 1A which is arranged between side bars 2A and 2A on both sides in a fluid circulation direction, and a corrugated fin 1B which is also arranged between side bars 2B and 2B on both sides in the fluid circulation direction and in which the fluid circulation direction is orthogonal to the corrugated fin 1A are laminated alternately via a tube plate 3 together with the side bars on both sides. On an exposure end surface on both end sides in an air circulation direction, a tip surface of the corrugated fin 1A arranged in an air circulation passage 5A is made to retreat to the inside of the flow passage with respect to the side surface of the side bar 2B and each end surface and the like of the side bars 2A and 2A. |
