A Method of Calculating the Heat Dissipation from Radiators to Cool Vehicle Engines

Several basic heat transfer equations have been utilized to enable the calculation of the thermal performances of vehicle radiator cores. The application of the calculation procedure to the two types of radiator matrix in general use has been shown in some detail, and results using these methods have been compared with experimental values. These correlations have shown that the calculation procedure can be used with confidence to predict matrix dissipations for Reynolds numbers in the water tubes of less than 1000, as found in automobile heater cores, as well as for the larger Reynolds numbers in the water tubes typical of automobile radiator cores.
