摘要：

In an impingement cooling system with one exhaust direction, the higher crossflow can influence the heat transfer coefficient on the target plate. There are dimpled plate and rib-roughened plate as the target plate in the present study. The presence of the roughened plates is in order to enhance the turbulent intensity of the crossflow and enhance the heat transfer coefficient on the target plate. The present study has been measured by the transient liquid crystal method. The heat transfer results of the dimpled plate are higher compared to those of the rib-roughened plate.
