Claims

[Scope of utility model registration request]

Refrigerant pipes with a flat cross section are arranged in a meandering manner so that the flat surfaces are parallel to each other at predetermined intervals, and ladder-like needle-like corrugated fins are installed in the space formed between the flat surfaces in the width direction of the refrigerant pipe. In the heat exchanger installed in a meandering manner parallel to each other, the needle-like portions of the corrugated fins have a circular cross section, and the needle-like portions adjacent to each other alternately protrude in opposite directions with respect to the reference plane. A heat exchanger.
