Radiators are heat exchangers used for cooling and heating purposes to transfer thermal energy from one medium to another. Some radiators were designed to operate in vehicles, homes, and electronics. The radiator is always a source of heat for its environment, as it can either be used to heat this atmosphere or to cool the supply of liquid or coolant. Despite the name, most radiators use convection to transfer the bulk of their heat. An automotive radiator is a cornerstone of an automotive cooling system that plays a major role in transmitting heat from engine components to the atmosphere through its complex system and operation. It is nothing, but a form of heat exchanger designed to transfer the heat from the warm coolant of the engine to the fan's blown air. The cycles of heat transfer take place from the coolant to the pipes, then through the fins from the tubes to the water. Radiators are used to cool internal combustion engines, especially in vehicles, as well as in piston-engine aircraft, railway locomotives, power generating plants or any related use of such applications. The main function of the automotive radiator is to cool the engine bypassing the coolant through the water jackets of the cylinder. The project's main goal is to design a radiator and analyze radiator CFD using Nanofluid. Radiator development is performed in the 2014 premium code of solid plays. And, CFD analysis is performed in simulation software for a strong workflow.
