This book chapter discussed impingement jet cooling. Jet impingement achieves locally high heat transfer on an interested surface. For these reasons, the impinging jet cooling technique has been widely used in many industrial systems such as gas turbine cooling, rocket launcher cooling and high-density electrical equipment cooling in order to remove a large amount of heat. In this chapter, experimental and numerical investigations are reviewed on flow and heat transfer characteristics of impinging jets. The review included the general single jet and jet impingement; their active controls; high speed jet flows and jet impingement; liquid impinging jet cooling; array jet impingement; array jet impingements on effusion surface. In detail, to enhance the heat transfer in single and array jets, there is discussion on design and control of nozzle geometry, nozzle insertion, jet vibration, secondary injection, and suction flow. In addition, effects of various factors have been concerned with different operating conditions (crossflow, rotation, compressible flow, working fluid, etc.) and combined techniques (rib turbulator, pin fin, dimple, effusion hole, etc.).
