Heat Transfer FINS
Introduction Fins are generally used to enhance the heat transfer from a given surface. Application areas of fins are: 1. Radiators for automobiles 2. Heat exchangers of a wide variety, used in different industries 3. Cooling of electric motors, transformers, etc. 4. Cooling of electronic equipment, chips, I.C. boards etc.
Types of fins: There are innumerable types of fins used in practice some of the more common types are shown in Fig. Fins of rectangular(a), circular(i), triangular(d), and conical(g)
Energy going into the element by conduction = (Energy leaving the element by conduction) + Energy leaving the surface of the element by convection) ??= ??+??+ ?????
