Abstract
An evaporator includes a flat tube extending in a vertical direction and having a drain groove for guiding condensed water downward, at a middle portion thereof in an air flow direction. A corrugated fin joined to the tube is divided by a gap portion into an air upstream side first fin and an air downstream side second fin. The gap portion faces the drain groove of the tube. Accordingly, condensed water produced at the air upstream side first fin can be smoothly discharged from the evaporator through the drain groove.
