Abstract: This work aims to give new results about the effect of the outlet opening of heat exchanger on its cooling quality. Three outlet opining locations have been studied in order to determine the best location that maximizes the efficiency of the heat transfer. The flow velocity at the inlet of the heat exchanger was also studied. It is worth noting that the research was carried out in a numerical way using ANSYS-CFX simulator.The latter solves both of energy and momentum equations using finite-volume method. Three pertinent parameters are considered here: the velocity of the flow at the inlet port of heat exchangers was controlled in terms of Reynolds number in the range 5 to 40. The pattern and the intensity of thermal transfer, the latter being controlled by the Richardson number selected between the values 0 and 1. The simulation was done for a simple and incompressible fluid. The results of this research showed that there is a possibility to raise the efficiency the heat exchanger if the outlet hole is placed at the bottom of the right side.
