The electronic equipment is often required to operate at various orientations in the real world applications. This is especially critical to the tower or pole or roof top mounted electronics under natural convection. However, it appears that no study has ever been made to examine the effects of orientations of the heat sink over full 90 degrees range from the vertical to the horizontal positions. Therefore, the present study is focusing at the analysis of natural convection heat transfer over the wide range of heat sink orientations to fulfill the needs for the industry.
