Abstract

The paper aims at the study of the cooling system in the household cooler by replacing honeycomb meshing into the radiator. Heat transfer from the radiator can be improved by maximizing the heat transfer area and increasing the heat transfer rate. In this paper, it is focused on increasing heat transfer rate by using MgO nanoparticles in suspension. A Thermophysical property has been increased in heat transfer material. Water was used earlier as a coolant in the radiator, as it is readily available and holds heat due to its specific heat property. A mixture of water and ethylene glycol was also effective as a coolant in the radiator. Advancement in coolant technology by introducing a new generation heat transfer fluid called “Nanofluids” in nanotechnology. This fluid has higher thermal conductivity compared to earlier conventional coolants. Nanoparticles dispersed in water, ethylene glycol or any carrier fluid are called nanoparticle. This paper deals with the experimental investigation of the existing cooler by modification in cooler. Introducing radiator in place of honeycomb meshing through which nanofluid is passed.
