Thermal management is one of the most challenging and innovative aspects of the automotive industry in the modern world. The efficiency of the vehicle cooling framework unequivocally relies upon the air stream through the radiator core. Significant developments in the automotive thermal management are being embraced in the field of radiator material and coolant.The radiator shouldn't be exclusively credited for the vehicle's reliable engine cooling system. There are other auto parts that play an essential role in keeping engine temperature at a manageable level. The fan shroud is an important component of the cooling fan. While thefan is responsible for drawing in low-temperature air, the fan shroud's job is to ensure this air gets to the radiator core. By assisting airflow in the engine compartment the fan shroud helps in expelling excess heat from the engine. The fan shroud also prevents the recirculation of heated air through the cooling fan. This research work endeavours to bring forth a new design and an improvement in the cooling system ubiquitous in the new era of modern engineering. An extensive iterative process has been undertaken to develop the most effective shroud design which has been validated with the virtual results on a standardised radiator with quantified thermal properties. SolidWorks has been used for modelling while meshing and CFD Analysis has been performed in FLUENT Environment. A uniform pressure distribution was observed across the face of the radiator core which expanded the proficiency of the radiator and hence attaining a 5% increase in heat dismissal when contrasted to a radiator without a fan-shroud combination. These results can be used to moderate the dimensions of the radiator for compact packaging.
