Column rib cooling structure with fillets and recesses

The invention provides a column rib cooling structure with fillets and depressions. The column rib cooling structure comprises column ribs, the fillets and the depressions. The column ribs are used for connecting the end walls, annular fillets are arranged at the joints of the column ribs and the end walls, and pits are formed in the surfaces of the annular fillets. The diameter of the middle section of the column rib is small, so that the flow resistance of a column rib cooling channel is reduced. And the heat transfer performance of the peripheral wall surface of each column rib and the heat transfer performance of the wake flow area at the rear part of the column rib are improved through the recesses on the surfaces of the fillets, and the heat transfer uniformity is improved. Therefore, the column rib cooling structure provided by the invention has higher heat transfer and cooling performance and lower flow resistance. 本发明提供了一种具有圆角和凹陷的柱肋冷却结构，包括柱肋、圆角、凹陷。柱肋用于连接端壁，柱肋与端壁的连接处设成环形圆角，环形圆角表面带有凹陷。柱肋的中间段直径较小，这有利于减小
