This paper presents a set of parametric studies of heat dissipation performed on automotive radiators.\nThe work�s first step consists of designing five radiators with different fin pitch wave distance\n(P = 2.5, 2.4, 2.3, 2.2, 2.1 mm). Then, we proceed to the fabrication of our five samples. The\npurpose of this work is to determine through our experiment�s results which one have the best\ncooling performance. This numerical tool has been previously verified and validated using a wide\nexperimental data bank. The analysis focuses on the cooling performance for automobile radiator\nby changing several dimensions of the radiator fin phase as well as the importance of coolant flow\nlay-out on the radiator global performance. This experience has been performed at Hubei Radiatech\nAuto Cooling System Co., Ltd. For the cooling performance experience, we use JB2293-1978\nWind Tunnel Test Method for Automobile and Tractor Radiators. The test bench system is a continuous\nair suction type wind tunnel; collection and control of operating condition parameters can\nbe done automatically by the computer via the preset program, and also can be done by the user\nmanually. The results show that the more we increase the fin phase, the better the cooling performance\nwill be and we also save material so the product cost will be cheaper.
