Claims

[Scope of utility model registration request]

A group of fins arranged parallel to each other and at regular intervals, a group of heat exchanger tubes that pass through this group of fins, and each fin in the gap in the step direction of this group of heat exchanger tubes, facing the airflow from the surface of these fins. and a cut-and-raised piece portion formed by aligning the cut-and-raised pieces at a predetermined inclination angle in the direction of air flow, and the cut-and-raised piece portion is formed in at least two stages, and one of the raised pieces is formed in at least two stages. A heat exchanger configured such that the inclination directions of one cut-and-raised piece and the other cut-and-raised piece are opposite to each other.
