Performance Analysis of Plastic Fin-tube Heat Exchangers for Anti-corrosion and Anti-fouling

Plastic materials have the advantage of anti-corrosion,but the thermal conductivity is quite low,which limits the performance of heat exchangers.The thermal conductivity of plastics can reach 20 W/(m·K) now.The performance of heat exchangers made of copper,stainless steel or high thermal conductivity plastic was compared.It was found that the performance of high thermal conductivity plastic heat exchanger was close to that of copper or stainless steel.The anti-fouling character was further considered and the performance of plastic heat exchanger was even better.These results showed that the heat exchanger made of high thermal conductivity plastic would have a good prospect in the anti-corrosion applications.
