Overall Performance of Heat Sink-Fan/Pump Unit and the Optimum Design

Performance of a forced-convection-cooling fin array in practical use should be evaluated taking its pressure-loss characteristics into account. On the other hand, the influence of the pressure loss on the cooling performance of a fin array is strongly dependent on the pressure-rise characteristics of fans/pumps driving the cooling fluid. From this poing of view, total performance of a forced-convection fin-array is analyzed in the present report considering its pressure loss and the performance of applied fan simultaneously. Based on this result, the optimum design method for forced-convection-cooling fin arrays is presented.
