In the present work of experimental investigation, the heat transfer performance of Spiral Tube Heat Exchanger (STHE) is studied by manufacturing the heat exchanger. STHEs are known as excellent heat exchanger because it is compact in size and having high heat transfer ability. The STHE consists of copper coils in the spiral shape and placed inside the shell which is made of Stainless Steel. The spiral shape coil is made by bending the straight copper tube of 10 mm inside diameter. The heat exchanger uses 3 such spiral coil brazed with straight header tube of 25 mm inside diameter and at a distance of 15mm apart, the number of turn in a spiral coil is four. Pump is used for circulation of water in both circuits. Cold water is circulated through spiral coil which entered at the periphery and comes out from centre; hot water is entered at the bottom centre of shell and comes out from the top of the shell. The inlet temperature range of hot water and cold water is 50 to 80°C and 30 to 48°C. Mass flow rate range of hot water and cold water is from 0.0633 kg/s to 0.0833kg/s and 0.01 kg/s to 0.0833kg/s.

Experimental data are presented from studies of turbulent heat transfer at high fluxes to water flowing in vertical tubes at supercritical pressures. A comparison of data for upward and downward flows indicates an effect of natural convection.
