Abstract (en)
[origin: EP0798448A2] The surface is subjected to hot gas on one side and has a coolant duct (5) on the inside. The coolant duct is connected to the outside of the surface (3) by angled openings (10) through which coolant, namely air, is ducted over the outer surface. To enhance the outflow, deflectors (15) lie in the duct upstream of the openings and inside of the surface. This deflects the coolant away from the surface to an inward directed shape of the duct. This guides the coolant flow into the openings. The remainder of the duct has other flow control inserts (21) as well as supports (20) between the outer surface and the inner duct wall. The supports are rod shaped while the flow deflectors can be ribbed. The coolant forms a film over the outer surface.
