Numerical analysis was carried out to examine the heat transfer and pressure drop characteristics of Plate Heat Exchanger(PHE) for absorption using Computational Fluid Dynamics(CFD) techniques. The Thermal performance and pressure drop are investigated. The computational model is a tree-dimensional narrow channel with angled triangular undulations. Geometric condition of PHE was port size 25㎜, channel plates area 3,465 ㎟. The main operating conditions in PHE, were taken a various Reynolds munber(from 1000 to 8000). The optimum flow pattern were presented with variation of pressure drop.
