Abstract

The car's cooling system is crucial for keeping the engine at a safe temperature. According to the available literature, radiator fins and microchannels might use some small improvements. Poor thermophysical qualities of conventional heat transfer fluids lead to inefficient engine cooling. High-performance heat transfer fluids with optimal thermophysical qualities must be used to combat this. A lighter car with a more powerful engine might be achieved using a more efficient thermal fluid that allowed for a smaller radiator. In this study, we provide a quick analytical method for assessing radiator performance in an internal combustion engine. The effects of temperature on density and specific heat at constant pressure are studied, together with other cooling properties such as fluid flow rate, effective cooling surface area, coolant passage tubes, and heat dissipation rate. Nanofluid is a prospective improvement option because of its potential to increase radiator efficiency by providing a higher heat transfer coefficient compared to water and ethylene glycol. The usage of nanofluid in conjunction with cutting-edge radiator design has the potential to vastly improve cooling efficiency. As an example, we model and simulate the heat transfer rate and temperature distribution in a graphene nanofluid radiator using Ansys.
