碩士 / 元智大學 / 機械工程學系 / 94 / This paper has investigated the performance of the plate-fin heat exchangers numerically. The validity of the used CFD software was confirmed first by comparing the obtained numerical results of the fin surface temperature distribution and the region of the condensation on the fin surface with the measured data by previous experiments. The results of this thesis can be used as a guildline of the designers of heat exchangers.
The parameters studied in the present work include the relative humidity of the inlet air, the height of the fin, the width of the fin, the space between the fins, the thickness of the fin, the velocity of the inlet air and the base temperature of the fin. From the simulation results, it has been observed that the corresponding fin performance becomes worse with higher relative humidity of the inlet air, lower height of the fin, smaller width of the fin, narrower space between the fins, thinner of the fin, faster velocity of the approaching air and highter base temperature of the fin. It is also found that the most influential parameter is the thickness of the fin.
