This book provides an investigation of the overall design of a car radiator. For the specified requirements of heat dissipation from a car engine, the methods to optimize its performance have been analyzed. The proper amount of heat that can be transferred by varying parameters such as number of tube rows, fin density etc. has been calculated. The radiator material, size, tube area, core size was defined to obtain the heat rejection needed for a typical engine at normal car speeds. The usage of louvered fins becomes significant in radiators owing to requirement of high amount of heat...
