Abstract (en)
[Problem to be Solved]In a condition in which frost formation is likely to occur as in a cold region or at midwinter, frost formation cannot be suppressed, and there are involved generation of air blockade, an increase in draft resistance, and a reduction in an amount of air passing through the heat exchanger, resulting in deterioration in heat exchange performance.[Solution]Front edge cutouts 18 are provided in a plate-like fin 11 including a flat portion 14, tube insertion cutouts 16, and collar portions 17, the front edge cutouts 18 extending from at least a part of airflow upstream side surfaces of flat tubes 12 inserted in the tube insertion cutouts 16 to the flat portion 14.
