WebApr 1, 1998 · The present study explores the heat transfer enhancement induced by arrays of cubic fins. The fin element is either a cube or a diamond in shape. The array configurations studied include both in-line and staggered arrays of seven rows and five columns. Both cubic arrays have the same geometric parameters, i.e., H/D = 1, S/D = … 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 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 transf…
