とを特徴とする熱交換器コア。 A plurality of flat tube groups, each consisting of a large number of flat tubes arranged in parallel at a predetermined interval, are arranged in multiple rows in the direction of air flow, and a single row of flat tubes is thermally connected between the parallelly arranged flat tubes. In a heat exchanger core in which corrugated fins are interposed and arranged separately, in the air flow direction, a flat tube with a long tube diameter with a long tube diameter and a short tube diameter with a short tube diameter on a long tube diameter. Two long pipe diameter flat tubes that are adjacent to each other and are arranged opposite to each other on both sides of the corrugated fin are shifted in the air flow direction so that their respective ends on the adjacent sides are close to each other. A heat exchanger core characterized in that a heat exchanger core is arranged in the following manner.
