This study is a numerical study. It investigates the steady state flow of fluid by natural convection in three dimensions as well as the transfer of heat for a set of innovative shapes of fin array. This study utilized four different shapes of fin array as well as the absence of fins. The different forms are as follows: straight, vertical (sine wave along y-axis), horizontal (sine wave along z-axis) and sweep (sine wave along both y and z axis). We examined the following parameters of the fin: geometrical dimension and thermal properties. In the steady state thermal analysis, an analysis of the differences in temperature regarding the distance at which heat flow takes place through the fin is carried out using CFX Ansys 15. The result shows that the sine wave along z-axis increases the transfer of heat more than the fin array of other shapes. Nusselt number increased as a result of the increasing heat flux which is exerted on the base as a boundary condition.
