A cooled multi-wall liner is provided having an outer wall, an inner wall and a porous midsection disposed therebetween, attached to both walls. The outer wall includes a plurality of first apertures. The inner wall includes a plurality of sections separated by gaps. Fluid on the outer wall side of the liner at a pressure greater than fluid on the inner wall side of the liner may enter the liner through the first apertures, be diffused within the porous midsection, and exit the liner through the gaps between the sections of the inner wall.
