Performance improvement of cooling tower by using various types of fins

Abstract

Cooling towers are a really important a part of many chemical plants. The primary task of a cooling system is to reject heat into the atmosphere. They represent a comparatively inexpensive and dependable means of removing low-grade heat from cooling water. The make-up water source. Cooling towers are ready to lower the water temperatures of devices that use only air to reject heat, just like the radiator during a car, and are therefore more cost-effective and energy efficient. to enhance the heat transfer rate is required higher surface area for dissipation of heat. here to increase the performance of cooling tower, we are use fins. Fin are the extended surface protruding from a surface or body and they are meant for increasing the heat transfer rate between the surface and the surrounding fluid by increasing heat transfer area. we increase the rate of heat transfer as good as possible by use of different fin geometry, in this paper we uses rectangular fin and circular shape fin geometry. On comparison, rectangular configuration provides the best heat transfer than that of other configurations. The effectiveness of rectangular fin more as compare to other configuration of fin.
