In this experimental study, a triple concentric tube heat exchanger (TCTHE) is designed and fabricated which consists of three copper tubes of diameter 41.2 mm, 25.35 mm and 12.6 mm and the length of the tubes are 580 mm, 740 mm and 857 mm, respectively. The thickness of the outer, middle and inner tubes are 1.25 mm, 0.94 mm and 0.80 mm, respectively. The objective of this study is to reduce the lengthnd material cost as well as increase the heat transfer surface area by adding an intermediate tube to the double concentric tube heat exchanger. The performance of the heat exchanger for different inlet temperatures and mass flow rates are estimated and analyzed. From the experimental results, it is found that the overall heat transfer coefficient is increased with increasing mass flow rate for hot and cold fluid. And also, overall heat transfer coefficient of the equivalent double concentric tube heat exchanger is compared with that of the TCTHE and found better performance. For the same heat transfer area, the length of the heat exchanger is 65.17% reduced compared to double tube heat exchanger.
