An automobile cooling system regulates engine surface temperature for engine optimum efficiency. Recent advancement and development in engine for power forced engine cooling system to develop new strategies to improve its performance efficiency. Also to reduce fuel consumption along with controlling engine emission to mitigate environmental pollution norms. This paper throws light on parameters which influence radiator performance along with reviews some of the conventional and modern approaches to enhance radiator performance. This review paper Focus on the various research papers regarding experimental, CFD and Numerical analysis to improving automobile radiator efficiency.

INTRODUCTION adiators are heat exchangers used to transfer heat or thermal energy from one medium to another for the purpose of cooling and heating. Automobile radiator is used to cool down automotive engine. If it’s not done various problems like knocking, piston deformation, cylinder deformation etc. can happen. If radiator works properly cooling system will work properly in turn engine performance will increase. Radiators are used for cooling internal combustion engines, mainly in automobiles but also in piston-engine aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Internal combustion engines are often cooled by passing a liquid called engine coolant through the engine block, where it is heated, then through the radiator itself where it loses heat to the atmosphere, and then back to the engine in a closed loop. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator [22], [23]. Fig.1.Radiator with its Components II. LITERATURE SURVEY Yiding Cao and KhokiatKengskool [1], had gave application of the heat pipe in an automotive engine was introduced. In this application, heat pipes were incorporated into the radiator of the automotive engine for more efficient heat transfer. The cooling load of the radiator can be increased for heavy-duty engines, while the power consumption of the cooling fan can be reduced for higher energy efficiency. Heat pipes including two-phase closed thermo siphon were two-phase heat transfer devices with an effective thermal conductance hundreds of times higher than that of copper. For the terrestrial applications, gravity was often used to assistant the return of the liquid condensate and no wick structure was needed inside the heat pipe. A small amount of working liquid was filled in a tube or other type of container. Air was evacuated from the container and the container was sealed. Heat was applied to the evaporator section, which causes the liquid to vaporize. The vapor then flows from the hotter section due to the higher vapor pressure to the colder section of the heat pipe, where it was condensed. The liquid condensate then returns to the evaporator section from the condenser section under the assistance of gravity. Hwa-Ming Nieh, Tun-Ping Teng, Chao-Chieh Yu R
