Abstract: A heat receiving block formed of carbon material having a through hole; a cooling tube formed of copper alloy fitted in the through hole of the heat receiving block; cylindrical material of interlayer disposed between the heat receiving block and the cooling tube; and brazing material layers inserted between the material of interlayer and the heat receiving block and between the material of interlayer and the cooling tube, also a slit which penetrates the heat receiving block and the material of interlayer over thickness of the heat receiving block and reaches the cooling tube on the back side of the heat receiving surface. It can provide heat receiving tile formed of carbon fiber composite material for high heat flux component such as a first wall of nuclear fusion reactor, which is produced by metallurgically joining carbon material with copper alloy and has higher cooling efficiency than conventional heat receiving tiles.

Abstract: A method of manufacturing high-heat-load equipment including a carbon material and a copper alloy material which are joined with each other includes; forming a titanium thin layer on a surface of the carbon material; positioning the carbon material so that the titanium thin layer is opposed to the copper alloy material while an interlayer is interposed between the carbon material and the copper alloy material; inserting a brazing material sheet into a space between the carbon material and the interlayer, as well as into a space between the interlayer and the copper alloy material, so as to prepare an assembly of the materials; and subjecting the assembly to a vacuum brazing process and further to an aging process.
