Abstract
A flat tube heat exchange apparatus that has flat tubes arranged at a regular pitch in the step direction which is orthogonal to the row direction of fins. If the step direction pitch of the flat tubes is defined as Dp, the coefficient of Dp is k, and if 0<k<0.5 or 0.5<k<1, the distance between a fin end at one side in the step direction of the fins, and the center of a flat tube in the thickness direction is k·Dp, and the distance between a fin end at the other side in the step direction of the fins, and the center of a flat tube in the thickness direction is (1−k)·Dp.
