A Review on Effect of Microchannel and Nanofluids on Cooling Capacity of Radiator

With an increase in demand for automobile vehicles, it becomes necessary to improve the performance of an engine. The cooling system of vehicle is one of the important parameters that significantly affect engine’s performance, cooling capacity  of radiator is affected by various parameters like, coolants, nanofluids, materials, tube configurations, design of fan core, mass flow rate of both coolant as well as air passing over etc. This review focuses  on  the  use  of  microchannels  nanofluids  in radiators in order to improve its efficiency. With increased heat transfer rate, fuel economy also increases which is the indication of the improved performance of an engine. It  has  been proven that, due to a larger surface area, microchannels possess higher heat transfer rate. Various channel configurations are studied from the literature review with different conditions. Due to recent developments in nanotechnology, got interested in using nanofluids in conventional heat transfer fluids i.e. coolant to improve their heat transfer characteristics. This review focuses on the effects of the use of microchannel nanofluids in the automobile radiator
