An inexpensively manufacturable arrangement for the cooling of thermally highly loaded components, for example the combustion chamber of a gas turbine, comprises cavities ( 4 ) provided on the thermally loaded inner surface/air exit side ( 3 ) of the wall ( 1 ) of the component which are supplied with a cooling medium from the outer surface/air inlet side ( 5 ) via cooling air openings ( 6 ) and which are covered by a heat resistant wire mesh ( 7 ) of a certain permeability. The cavity, which acts as pressure accumulator, forms, in connection with the wire mesh, a uniform pressurized-air film ( 8 ) for the cooling and heat shielding of the wall surface.
