摘要:
This heat receiving tile formed of CFC is provided with a heat receiving block formed of a carbon fiber composite material and having a through hole, a cooling pipe inserted through the through hole of the heat receiving block, a buffer material provided to an outer periphery of the cooling pipe, a first brazing portion joining an inner surface of the through hole with an outer surface of the buffer material, a second brazing portion joining an inner surface of the buffer material with an outer surface of the cooling pipe, and a material discontinuous portion extending from a heat receiving surface of the heat receiving block up to the outer surface of the cooling pipe over a full length of the heat receiving block in an axis direction of the through hole. The heat receiving tile formed of CFC, which does not include a defect to decline a cooling efficiency such as a peeling between members configuring the heat receiving tile and a crack of the members, can be provided.
摘要:
This heat receiving tile is provided with a heat receiving block 11 formed of a carbon material and having a through hole; a cooling tube 16 formed of a copper alloy and fitted in the through hole of the heat receiving block; a cylindrical material of interlayer 14 disposed between the heat receiving block and the cooling tube; and brazing material layers 13, 15 inserted between the material of interlayer and the heat receiving block and between the material of interlayer and the cooling tube, and also a slit 21 which penetrates the heat receiving block and the material of interlayer over the thickness of the heat receiving block and reaches the cooling tube on the back side of the heat receiving surface. It can provide a heat receiving tile formed of a carbon fiber composite material for high heat flux component such as a first wall of a nuclear fusion reactor, which is produced by metallurgically joining a carbon material with a copper alloy and has a higher cooling efficiency than conventional heat receiving tiles.
