HEAT TRANSFER BY FINS

Text from page-2

What is fin…?? A fin is a surface that extends from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction, convection, or radiation of an object determines the amount of heat it transfers. Adding a fin to an object, increases the surface area resulting in an effective heat transfer.
