摘要

This study presents the airside performance of the fin-and-tube heat exchangers having plain fin geometry with a larger diameter tube (Dc = 15.88 mm). A total of nine samples of heat exchangers subject to change of the number of tube row and fin pitch are made and tested. Tests are conducted in a wind tunnel at controlled environment. It is found that te effect of fin pitch on the sensible j factor is, in general, diminished with the rise of tube row. The influence of tube row on the airside performance is rather small for both heat transfer and frictional characteristics at a fin pitch of 2.1 mm and when the Reynolds number is less than 4000. A slight deviation of this effect is encountered when fin pitch is increased to 2.54 mm or 3.1 mm. This is because the condensate adhered phenomena..
