A coolable wall configuration includes a slot formed between two wall portions for carrying coolant fluid in a downstream direction wherein the slot is divided into a plurality of parallel channels by as plurality of parallel barrier walls extending in a direction perpendicular to the downstream direction, the barrier walls having openings therethrough at regular intervals to interconnect the channels, wherein the openings in adjacent barrier walls are staggered so that cooling fluid flowing through each opening impinges upon a wall portion of the next barrier wall and ultimately traverses a square wave-like flow path as it moves downstream from channel to channel. This configuration is particularly suitable for use in the trailing edge region of an airfoil.
