EXTENDED SURFACES FIN PERFORMANCE FIN EFFICIENCY .Fin Efficiency may be defined as the ratio of actual heat lost by the fin to the maximum heat lost by the fin. The maximum rate at which a fin could dissipate energy, is the rate that would exist, if the entire fin surface were at the base temperature lact Qmax ninc erefore, Qact fin Qmax A.

In case of extended surfaces, effective heat transfer area on the side of the extended surface is increased. Passive techniques hold the advantage over the active techniques as they do not require any direct input of external power. These techniques do not require any direct input of external power; rather they use it from the system itself which ultimately leads to an increase in fluid

The heat flow from a primary surface with fins attached is a combination of the flow from the area of the surface not covered by the fins and the flow through the fins. Therefore knowledge of the temperature distribution through both the primary surface and the attached fins is necessary in order to design the extended surface assembly.

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 convection.
The surface area exposed to the surroundings is frequently increased by the attachment of protrusions to the surfaces, and the arrangement provides a means by which heat transfer rate can be substantially improved. The protrusions are called fins or spines, and these extensions can take a variety of forms.
Fins are used to enhance heat transfer, and the use of fins on a surface cannot be recommended unless the enhancement in heat transfer justifies the added cost and complexity associated with the fins.
