Abstract:
Fin is heat-sinks that have extend surface from its base. It enhances the rate of heat transfer. Fin has two types, one is flat, pin. Effect of geometry which includes size, shapes, area, is considered. In arrangement of pin fin includes array pattern of pin fins in particular area or where it needs to setup on external surface. In this paper, We discussed about different types of geometry and arrangements like Drop fin, Elliptical fin. Fin winglet, pin fin with dimple, plane fin, wavy fin etc. Pin fin has a better capacity of heat transfer then the flat plate. Also when we are using different types of plate with dimples, distance between two consecutive pins and whole, rectangular pin or cylindrical pin, winglet type fins etc. This paper is concentrated only on heat exchanger heat transfer who discussed about how to increase the heat transfer rate with using different types of fins and in which is the best for high heat transfer in different applications. Also which type of arrangement is suitable for heat transfer? Different rates of geometry and arrangements of fins in particularly for pin fin are described in this paper.
