Abstract

An improved heat transfer assembly includes a textured impingement surface and means for impinging cooling air directly upon the textured surface. A component includes a surface textured to increase convective heat transfer with minimal increase in resistance to conductive heat transfer through the component. The textured surface can comprise an array of closely spaced hemispherically shaped protuberances. A method is disclosed for texturing a surface with discrete laser welds.
