Cooling fins are the most used thermal devices. They are used mostly in thermal control of electronic equipment as well as in compact heat exchangers. In this paper, three types of fins are analyzed: longitudinal, spine and annular; each of them has three possible shapes: constant thickness, triangular and parabolic. The paper considers effect of the tip condition and fins with convective tips are compared to insulated tip fins. The comparison is important mostly because usually the solutions for insulated tip fins are easier and available for more cases.
