<p>A heat exchanger (1,2) for a motor vehicle including a pair of tanks (1b, 1c; 2b, 2c) located apart from each other and a core part (1a, 2b) located between the pair of tanks (1b, 1c; 2b, 2c). The core part (1a, 2a) has a plurality of tubes (1d; 2d) and a plurality of corrugated fins (3; 20; 30) arranged between the adjacent tubes (1d; 2d), where the corrugated fins (3; 20; 30) are formed with a plurality of louvers (3a, 3b; 50, 51, 53). The corrugated fins (3; 20; 30) have an upstream projecting portion provided with a projecting portion (3c, 3d; 21, 22; 31, 32; 41, 42) so that cooling air (CA) converges downward to be conducted to the louvers (3a; 53) by the projecting portion (3c, 3d; 21, 22; 31, 32; 41, 42).</p> |
