Heat Transfer by Convection of a Heat Sink with Fins Calculator and Equations
Fins are used to increase heat transfer area and provide a cooling effect.
However, if h*A / P*k is greater than 1.00 the fins will insulate and prevent heat flow.
h = air film convective coefficient
A = exposed surface area of the fins.
P = perimeter of the fins.
k = fin material conductivity coefficient.
