PERFORMANCE ANALYSIS OF HEAT EXCHANGER BY REPLACING COPPER TUBES WITH POLYMER TUBE OR COMPOSITES MATERIAL

Abstract

In this thesis the polymer heat exchangers to the current technology in metallic heat exchangers. A review of
state of the art of polymer heat exchangers is presented and technological problems are identified. In a current metallic
heat exchangers copper tube is used for transferring the heat exchangers, copper tube is used for transferring the heat.
Since the thermal conductivity of the copper tube is high so when the copper tube transfers the heat there are some heat
losses. The thermal expansion coefficient of the copper tube is high so when the high temperature is achieved into the
copper tube than the shape and size of the copper tube also changes. Copper is a reactive metal so when the chemical
treatment process is done for removing the chocking defect, copper metal react with the chemical so strength of the
copper tube will be decrease. In this simulation models were developed and used to explore the thermal-hydraulic,
packaging and weight tradeoffs associated with polymer heat exchangers.
