Cooling towers are commonly used to reject heat from condenser water, heat exchanger, and other processing equipments. A cooling tower cools the hot water by a combination of heat and mass transfer. The hot water to be cooled is distributed in the tower by spray nozzles, splash bars, or film-type fill, which exposes very large water surface area to atmospheric air. A portion of the water will absorbs heat and converted in to a vapor at the constant pressure. This latent heat has been long used to transfer heat from water to the atmosphere. Lots of work have been carried out with wire mesh, zig-zag type fins and etc and measure the significant improvement in the efficiency and heat transfer rate of the cooling tower. So, if the spirals section or twisted tape types fins used in the cooling tower than it gives the better results in the enhancement of heat transfer rate or efficiency of the cooling tower. In this experimental work twisted tape has been mounted in vertical and horizontal direction with 5 sets of 4 raw and 4 columns. The maximum efficiency has been gained in cooling tower with vertical mounting twisted tape insert with 0.0208 kg/s mass flow rate of air.
