The Heat Balance Integral Method is applied to solve for the heat flow and temperature distribution in extended surfaces of different shapes and boundary conditions. In most cases the analysis is found to be identical to the exact two-dimensional solutions at Biot numbers for which the one-dimensional analysis is almost 100 percent off. Other possible extensions of the method are briefly described.
