Abstract: A heat shield is disclosed comprising a formed sheet having a thickness, an exterior shielding surface, and an interior shielded surface, wherein the exterior shielding surface comprises a multiplicity of protruding perforations. The protruding perforations comprise protrusions increasing surface area and generating turbulent flow, and small openings through the shield to allow convection air flow to pass through.
