Wet surface performance test of fin-tube heat exchangers with slit-wavy fin
물결형 슬릿핀이 장착된 핀-관 열교환기의 습표면 성능 실험
Abstract
In this study, the wet surface heat transfer coefficients and friction factors of the heat exchanger with slit-wavy fin were measured. Four sample cores of two or three row with fins of 12 fpi or 16 fpi were tested. Tests were conducted in a closed loop wind tunnel, where the heat exchanger was mounted at 45 degree inclination angle. The wet surface heat transfer coefficient was reduced following the procedure given in ARI 420-81. During the course, new definitions of the
