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.

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.

Heat transfer enhancement can have benefits beyond the heat exchanger itself, affecting the whole system of which the heat exchanger is a component. Three examples, relating to evaporation and condensation heat transfer enhancement, are given below. It will be noticed that the improvements brought about by heat transfer enhancement are the same as those attributable to compact heat.

Heat is defined in physics as the transfer of thermal energy across a well-defined boundary around a thermodynamic thermodynamic free energy is the amount of work that a thermodynamic system can perform.
Enthalpy is a thermodynamic potential, designated by the letter "H", that is the sum of the internal energy of the system (U) plus the product of pressure (P) and volume (V). For the Love of Physics - Walter Lewin - - Duration: Lectures by Walter Lewin.

The Biot number (Bi) is a dimensionless quantity used in heat transfer calculations. It is named after the eighteenth century French physicist Jean-Baptiste Biot (–), and gives a simple index of the ratio of the heat transfer resistances inside of a body and at the surface of a body.
This ratio determines whether or not the temperatures inside a body will vary significantly in space. Heat Transfer through a Wall R 1 R 2 R 3 Example – Book Problem a The window of a car is defogged by attaching a transparent, film-type heating element to its inner surface.
