Abstract

Exchange of heat is the most important processes in engineering science. The heat exchanger a device which is used to transfer the heat between flowing fluid.Contentious flow of the fluid in the tubes of the heat exchanger not only corroded the tube but it also degrade the quality of the fluid like; the changes in its thermal conductivity , mass flow rate, density and viscosity. To overcome this disadvantages the inner tube of the metal is replaced by the fluoropolymer tube which is not only chemical inert but also sustain the non- corrosive nature.The fluoropolymer tubes are extruded from high thermal conductivity PFA polymers which are used to obtain the nano–range of fluorinated layer in order to make steel surface hydrophobic.The biggest property of the PF-HEX units is that every component is made from the same fluoropolymer material. This is significant because the use of dissimilar material can make Parts of unit cycle from hot to cold at different rate. It ensures efficiency and long life.

Keywords: Perfuoropolyethers , Fluoropolymers , Thermal efficiency , Hydrofobic, (HEX ) Heat Exchanger.
