The forced-convection-cooling performance of a fin array is dependent on its pressure-loss characteristics as well as on the pressure-discharge characteristics of fans/pumps driving the working fluid. From this point of view, the overall performance of the forced-convection fin array has been analyzed, considering these characteristics and introducing anew dimensionless parameter F, which governs the overall performance. Based on the results, optimum design methods for forced-convection-cooling fin arrays in practical use are proposed.
