The present study describes the experimental results on the characteristics of he impingement heat transfer caused by three slot jets. Experimental values were obtained for the dimensionless space H=0.5-3, the dimensionless pitch P=6-16 and the Reynolds number Re=500-8000. For laminar impinging flow, they were compared with numerical results. For turbulent impinging flow, two peaks of the local Nusselt number were obtained behind the second nozzle. The position of he second peak approached the nozzle with the decrease of the space between nozzle and impinged surface. The average Nusselt number between the central and the second nozzle was determined by the ratio P/H and the Reynolds number based on the pitch of the nozzles.
