A heat exchanger is a device that is used for thermal energy exchange. It may be within the solid or solid fluid interface or within the gas itself having temperature gradient. Heat exchanger is vital from industry point of view having good efficiency and also having an economic running cost. Study is been conducting on enhancing the heat transfer rate. The paper proposes the research and practical work done on tube heat exchanger by using nanofluids which is a heat transfer augmentation technique.

Keywords: Heat exchanger, nanofluids, thermal conductivity, effectiveness
