This paper refers to the design analysis of automotive radiator in engine cooling system. This analysis aims to design the more compact radiator that transfers the equivalent amount of heat of the existing radiator. Both LMTD (Log Mean Temperature Difference) and ε-NTU (effectiveness-Number of Transfer Units) methods are commonly used for design and thermal analysis of radiator. In this paper, the design analysis of automotive radiator is described by using ε-NTU method. The results obtained from the analysis are presented. Finally, calculated results with actual values have been compared. This calculation can be done using MATLAB software.
