Walls that require cooling, including combustor walls of jet engines, having two members forming a waffle shaped structure are described. The dual member structure comprises passages for incoming air, which zigzag through part of the waffle structure. The air is then released to the combustor or exhausted elsewhere. Additionally, the need for a cool film on one side of the wall may be eliminated. The waffle shaped structure disclosed is relative easy to manufacture.
