  • 초록

    The effect of inclination angle on the heat transfer and pressure drop characteristics of the brazed aluminum heat exchangers is experimentally investigated. Three samples having different fin pitches(1.25, 1.5 and 2.0 mm) were tested. Results show that heat transfer coefficient is not affected by the inclination angle. However, the friction factor increases as the inclination angle increases with negligible difference between the forward and backward inclination. Both the heat transfer coefficient and the friction factor are the smallest at $F_p=1.5mm$ , followed by $F_p=2.0mm$ and 1.25mm. Possible explanation is provided considering the louver layout. Comparison with existing correlations is also made.
