Abstract
The presented dissertation is an experimental setup for heat exchangers designs first one is a simple tube air cooled heat exchanger without grooving, second one is air cooled heat exchanger with internal circular grooving and third one is internally curricular grooved air cooled heat exchanger with rectangular fins. In case of third design we are taking seven variations in successive rectangular fins to evaluate the performance of the heat transfer efficiency of the proposed heat exchangers by changing the distance of fins and hence the number of fins used in the proposed heat exchanger. We are changing the distance between the fins and its number until we get a constant or almost constant temperature drops. The proposed distance between the fins are 0.5 cm, 1.0 cm, 1.5 cm, 2.0 cm, 2.5 cm, 3.0 cm and 3.5 cm in seven proposed setup for the air cooled heat exchanger with 200, 102, 68, 52, 42, 35 and 29 fins respectively. From the proposed analysis we establish that the heat transfer rat
