An experimental investigation was performed using model packages mounted in five columns and up to twelve rows on the floor of parallel channels. Each package has the base area of 22×22mm^2, the total height of 17.6mm and is equipped with a finned heat sink. The fin geometries and arrangement, as well as the air velocity, were changed, and their effects on heat transfer from the packages and channel pressure drop were investigated. The difference of the heat transfer coefficient between a variety of finned heat sinks was evident at the upstream portion of the rows. On the other hand it was very small downstream. The heat transfer coefficient from the first package downstream of the missing package was found to increase to the level of complete mixing of cooling air. It was effective to place obstacles between the packages to promote mixing and to increase the heat transfer coefficient. However, the increment of the pressure drop did not change the per-pumping power heat transfer coefficient.
