Abstract：This work experimentally investigated the heat transfer behavior of confined slot jet impingement onto the metal porous heat sink. Air was used as impinging coolant, while the aluminum foams with 0.93 porosity and 10 pores per inch was employed. The length (L) and height (H) of the aluminum foam heat sink were fixed. Variable parameters were the jet Reynolds number (Re), the jet nozzle width (W_j) and the jet separation distance (C), Experimental results reveal that the wall temperature was minimal at the stagnation point (x=0) and increased along the channel axis Parametric studies indicate that increasing Re increasing the average Nusselt number (Nu) and the effect of W_j/H was negligible. Besides, increasing C/H slightly decreased Nu. Finally, the relationship among Nu, Re and C/H was suggested
