Abstract
The cooling of electronic parts has becomes a majour challenge in recent years due to the advancement in the design of faster and smaller components. The vise of liquid coolant has become more attractive due to the higher heat transfer coefficient achieved as compared to air cooling. Present work details the numerical and experimental analysis of cooling heal sources using water and dielectric oil (transformer oil). The experimental data were carried out al different flow rate and different heat flux. The flow is inlet from the upper surface of the lest section and exit from the sides. The effect of flow exit section was studied for different sections. Results shows that the case of the flow exit from the lower section which in the same level of the higher surface of the discrete heat souces is the best. Results shows also that the transformer oil is given a good coolant effect compared with water. Empirical correlation development from experimental to calculate the Nu. Resul;ts shows also good agreement between the theoretical and experimental results.
