Abstract
In this study, performance analysis of brazed compact heat exchanger is investigated experimentally. Chevron angle of brazed compact heat exchanger is 30°. Effectiveness analysis of brazed compact heat exchanger at different working conditions is examined. The highest effectiveness value is 49%. While mass flow rate is 0.21 kg/s, the peak value for heat transfer rate is obtained as 18 kW. This study shows that an increase in the Reynolds number results in an increase in Nusselt number. While Reynolds number is 2125.72, the peak value for Nusselt number is 40. Also, the raise in the Reynolds number causes the Nusselt number to increase, which raises the heat transfer coefficient, and the heat transfer coefficient also reduces heat transfer rate. In addition, exergy analysis of the brazed compact heat exchanger is made. The peak exergy loss value is 12.3 kW and the least exergy loss value is 5.03 kW for brazed compact heat exchanger.
