Heat Transfer from Extended Surfaces (FINS) Introduction. In this chapter, we shall discuss heat transfer from extended surfaces, also called Fins. Fins are generally used to enhance the heat transfer from a given surface. Consider a surface losing heat to the surroundings by convection. To increase the surface area, an extended heat transfer surface (called a fin) is widely used. Fins are a superior method when it comes to cost and reliability, so they are commonly applied to heat exchangers. This section introduces high performance fins which can be applied in high heat-flux applications to enhance heat transfer performance. Coverage of all facets of extended surface technology including, compact heat exchangers, periodic heat flow and boiling off finned surfaces. Focus on the theory, design, and applications of a broad range of surface types. Example problems used throughout to illustrate the use of expressions derived and/ or discussed in the text.

This book is printed on acid-free paper. 16 TRANSIENT HEAT TRANSFER IN EXTENDED SURFACES Introduction / Longitudinal Fin of Rectangular Profile / subject of extended surface heat transfer is one where analytical methods have been. A fin serves as an extended surface to enhance the heat transfer from a larger heated mass to which it is attached. We consider a fin in steady-state and find its shape that maximizes the efficiency. In the study of heat transfer, fins are surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing amount of conduction, convection, or radiation of an object determines the amount of heat it transfers. Increasing the temperature gradient between the object and the environment, increasing the convection heat transfer.
