摘要：A Heat Exchanger is a device built for the efficient heat transfer from one fluid toanother, whether the fluids are separated by a solid wall so that they never mix, or the fluids are directly incontact. Heat transfer by convection between a surface and the fluid surrounding can be increased by attachingto the surface called fins. Every year research in Heat exchanger technology is growing to develop efficient,compact and economical heat exchangers, all over the world. counter flow heat exchanger models weredeveloped. and reading were taken, The results were compared between each model and between hexagonal andsemi circular fins. The heat exchange dependencies of the heat transfer coefficient and the pressure drop areinvestigated through experimental . We have to increases the efficiency of the heat exchanger by changingvarious configuration of design. Overall heat transfer co efficient of the heat exchangers were calculate andcompare the results of hexagonal and semicircle fin ,select suitable fin which could produce high heat transferrate and efficiency than the other one.
