  • In order to study the heat transfer characteristics of channels with different ribs, 4 kinds of channels with different ribs were designed and the heat transfer characteristics of them were experimentally studied;the influence of different ribs and the impingement Re on their heat transfer characteristics were analyzed.The results show that the heat transfer characteristic at the region of stagnation point is different from that at rib region, and the heat transfer characteristic of channel with V-shape ribs is better than others.
