Résumé

Part 1 presents the airside performance of fin-and-tube heat exchangers with plain fin configurations. 18 samples were tested. The effect of the number of tube rows, fin pitch and tube diameter on the thermal-hydraulic characteristics was examined. The heat transfer characteristics were strongly related to the fin pitch. For the same fin pitch, the effect of the number of tube rows on the friction performance was very small. The effect of tube diameter on heat transfer performance is related to fin pitch as well. Part 2 relates a correlation for fin-and-tube heat exchanger. The proposed heat transfer correlation can describe 88.6% of the database within plus or minus 15%, while the proposed friction correlation can correlate 85.1% of the database within plus or minus 15%.
