Abstract
Clearance holding portions for holding a clearance between the adjacent plate fins are spaced from side edges of louvers by a predetermined distance in a direction perpendicular to a flowing direction of air and disposed at an upstream side of tubes in the flowing direction of the air. In this way, air flowing between the adjacent plate fins flows through the louvers without being disturbed by the clearance holding portions, so that an effect of the louvers for improving the heat exchange performance can be maintained sufficiently.
