Abstract

This paper establishes the three dimensional laminar mathematical physical model of dew point evaporative cooling in plate heat exchanger, according to the simplifying assumptions of the complicated course for heat and mass transfer and counter-current flow in dew point evaporative cooler ,using the CFD (computational fluid dynamics) and NHT (numerical heat transfer) method. By the numerical simulation of Fluent ANSYS, get the internal distribution of temperature field and concentration of water vapor field, and analyze the effects on dew point heat exchanger of perforation diameter, spacing and perforation mode which is set on the heat exchange plate between the dry and wet channel. The dew point efficiency of the optimized model and parameters approach to 71.2%.
