Abstract
Each tube and a corresponding fin satisfy all of the following relationships: Lp−t≧0.03Tr+0.22; Lp−t≦0.115Tr−1.14Tr+2.35; and Lp−t≧5Tr−8.3Tr+3, where Lp denotes a width of a sub-passages, Tr denotes a refrigerant passage height, and t denotes a plate thickness of the fin. The amount of a brazing material, which is present through an entire extent of the width of the sub-passage, is set to satisfy a relationship of 0.005≦S/L<0.5, where S denotes a size of a cross-sectional area of the brazing material, and L denotes a length of a center line of a corresponding portion of the fin, which is present through the entire extent of the width of the sub-passage.
