Cooling structure and airfoil

The cooling structure and the airfoil are used for improving the cooling effect of the airfoil, the cooling structure comprises a targeting wall, the targeting wall is used for being impacted by cooling gas, and the cooling gas impacts a target spot of the targeting wall; the cooling structure further comprises a turbulent flow part, and the turbulent flow part protrudes from the target wall and is used for applying disturbance to the cooling gas after impacting the target spot; the cooling structure further comprises an air film hole, an inlet of the air film hole is located in the turbulent flow part, the air film hole comprises an expansion section, and the expansion section provides an outlet of the air film hole. 一种冷却结构及翼型件用于改善翼型件的冷却效果，所述冷却结构包括靶向壁，所述靶向壁用于被冷却气冲击，冷却气冲击所述靶向壁的靶点；所述冷却结构还包括扰流部，所述扰流部自所述靶向壁突伸，用于对冲击所述靶点后的冷却气施加扰动；所述冷却结构还包括气膜孔，所述气膜孔的入口位于所述扰流部，所述气膜孔包括扩张段，所述扩张段提供所述气膜孔的出口。
