An extended surface is commonly used in reference to a solid that experiences energy transfers by conduction within its boundaries, as well as energy transfer by convection between its boundaries and its

surroundings. The extended surface is most often utilized in the removal of heat from a body. In this case, the extended surface is often referred to as a “fin”. A fin with a cylindrical shape and a high aspect ratio (length/diameter) is called a pin. Fins are often seen in electrical appliance cooling such as in a computer power supply or substation transformers. Fins are also used for engine cooling.
