Abstract

the heat exchanger is a device used to transfer heat between a solid object and a fluid, or between two or more fluids. Generally, radiators are heat exchangers used in automobiles to transfer thermal energy from one medium to another for the purpose of cooling and heating. In radiator, the hot liquid flows through the exposed pipes and transfers the heat to the air by fans. The heat exchanger is also widely using in space heating, air conditioning, power plants, etc. Since the heat exchanger is using in many industrial applications, the major problem arises during heat exchanger is low thermal conductivity. Low thermal conductivity of heat exchanger is mainly due to the conventional heat transfer fluids. In order to overcome this issue, an energy efficient heat transfer fluids are developed by suspending metallic or metallic oide nanoparticles in conventional heat transfer fluids which is known as “nanofluids”. Our objective is to improve the thermal conductivity by supplying the nanofluid as cold fluid in heat exchanger. These nanofluids are expected to have high thermal conductivity than the heat transfer fluids such as water, ethylene glycol and engine oil. The result of heat transfer property of cadmium oxide nanofluid flowing through the double pipe heat exchanger is presented and it is compared with the heat transfer rate of water flowing through the same heat exchanger. The other thermo-physical properties of cadmium oxide nanofluid and water are also investigated in this paper.
