Continuous technological development in automobile industries has increased the demand for high engine efficiency. A high efficiency of IC engine is not only based on its performance but also for better fuel economy and low emission. Lower a vehicle weight by use of optimum design and size of a radiator is a necessity for making the world green. There are several different approaches and any one of these can take to optimize the heat transfer performance of radiator design. extending surfaces and redesigning heat exchange equipment to increase the heat transfer rate has reached a limit, many researchers works to try and improve the thermal transport properties of the fluids by adding more thermally conductive solids into liquids. Liquid dispersions of nanoparticles, which have been termed “nanofluids”, reveal largely higher thermal conductivities than those of the corresponding base fluids.
