Circular cooling fins of diameter
WebAluminum circular cross-section test rods 90 cm in length with diameters of 3.18, 6.35, 9.53, and 12.7 mm were employed as fins. The 90 cm length was chosen, based on analytical calculations, to insure that the tip of the fin is at the same temperature of the adjacent fluid. Copper-constantan Web2–22 for fins on a plain surface and in figure 2–23 for circular fins of constant thickness. The fin surface area associated with each profile is also given on each figure. For most fins of constant thickness encountered in practice, the fin thickness t is too small relative to the fin length L, and thus the fin tip area is negligible.

WebIn the study of heat transfer, finsare surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction, convection, or radiationof an object determines the amount of heat it transfers. WebFins are most commonly used in heat exchanging devices such as radiators in cars, computer CPU heatsinks, and heat exchangers in power plants. They are also used in newer technology such as hydrogen fuel cells. Nature has also taken advantage of the phenomena of fins.
