| Abstract: | Radiator is an important element in the cooling system of vehicles. So, a lot of investigations on improving the operating performances of radiator have been conducted. As far as the study methods are concerned, it mainly consists of theoretical analysis method and experimental method. Nowadays, the latter is welcoming for the complexity of radiator's structure and the variability of its operating situations. The existing literatures indicated that the radiator's working performances including heat transfer, coolant pressure drop and air pressure drop, mainly depend on its operating parameters, e.g., the coolant inlet temperature, coolant flow rate and air velocity under given structure dimensions. In this paper, the experimental study on heat transfer performance of tube and fin radiator for vehicles has been carried out by means of the experimental optimum design on wind tunnel test rig. The remarkable levels of the factors affecting the experimental results were evaluated. Finally, the regression equations of heat flux, coolant pressure drop and air pressure drop have been obtained by means of regression analysis. These equations describe the effects of coolant inlet temperature, coolant flow rate and air velocity on heat flux, coolant pressure drop and air pressure drop respectively. |
