Heat transfer is the phenomena, of transfer energy (thermal energy) in between the systems or system and surroundings. And heat exchanger is the main device which is used for transfer of heat (thermal energy) in many industries like food industries, chemical industries, thermal power plant, air conditioning equipment etc. So because of heat exchanger importance, many heat enhancement techniques are adopted to improve the performance of heat exchanger. In the previous years, many research on passive techniques have been studied. This paper is the review of such techniques used in heat exchanger to improve the effectiveness. Twisted tapes, wire coils, ribs fins etc. are commonly used heat augmentation tools.
