| Summary: | The car cooling systems, was considered one of the most important parts which work in dissipated the heat is generating by engine of the car. This study used simulation of CFD to optimize the radiator thermal performance by changing the pipe material while maintaining the same cross-sectional area. By used water-Ethelyn-glycol mixture (50:50) as a hot fluid at flow rates of (12) and (24) litters/hour at different temperatures (85, 90, 95) oC, air was considered a cold fluid with different speeds, respectively (1.5, 2.5, 4.5, 5.5) m /s and its inlet temperature (35) oC . It was clear from the results that there was a significant convergence in heat transfer rates when replacing the pipe metal from copper to aluminium for the improved model compared to the basic model. They are approximately equal at some air velocity. with a small advantage for copper of approximately 5% in terms of heat transfer rate and overall heat transfer coefficient.
