Authors: Adekunle N.O, *Oladejo K.A, Momoh O.J
Fins is an integral part of any heating or cooling system. It is primarily responsible for improving heat transfer. The different characteristics of fins such as fin tip, base temperature, fin array, fin efficiency, fin effectiveness amongst others were studied in order to understand how they affect fin effectiveness and fin efficiency and propose a working algorithm which will be capable of flexible analysis and design which can be used in refrigerators and transformers. The result of numerical computation showed that the fin effectiveness and heat transfer through fins increases as the length and width increases. Though, efficiency increases with thickness and fin effectiveness decreases. The heat transfer surface area is a function of fin dimensions and fin shape, as the surface area increases the amount of heat transferred increases. Also, copper material had highest fin effectiveness and heat transfer. The fin efficiency can be improved by using a material with higher conductivity.
