Component with heat protected wall with cooling channels - has heat conductive layer on surface of cooling channel adjoining wall having matching layer and wall thicknesses

摘要

The cooling channel material has a heat conductive layer on the surfaces facing the adjoining cooling channels. These channels have opposite flows of cooling medium. The cooling channel material is pref. covered from the heat source by a heat-blocking material such as zirconium dioxide. The component part (1) with the protected wall has a heat-insulating layer (8) between the wall (3) and heat conductive layer. The wall thickness of the cooling channel material and the coating thickness of the heat conductive layer correspond so that the thermo strains in the cooling channel material remain below the permissible thermal strength boundary values of the cooling channel material. USE/ADVANTAGE - For hypersonic drives. Increased service life when used in various applications such as rocket jets.
