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.

First claim

The invention claimed is:

1. A method of manufacturing a heat receiving tile formed of a carbon fiber composite material used for a high heat flux component, comprising the steps of:
disposing a first thin film type of brazing filler metal on an inner peripheral surface of a through hole of a heat receiving block which has a slit on a back of its heat receiving face;
disposing a cylindrical material of interlayer, which has a single slit, inside of the first thin film type of brazing filler metal while placing the slit of the cylindrical material of interlayer at a same position as a slit of the heat receiving block;
disposing a second thin film type of brazing filler metal on an inner peripheral surface of the material of interlayer;

disposing a cooling tube inside of the second thin film type of brazing filler metal, so as to prepare an assembly thereof; and
subjecting the assembly to a vacuum brazing process and further to an aging process.

2. The method of manufacturing the heat receiving tile formed of a carbon fiber composite material according to claim 1 , wherein the first thin film type of brazing filler metal is disposed so as to be discontinuous at the slit of the material of interlayer prior to brazing.

3. The method of manufacturing the heat receiving tile formed of a carbon fiber composite material according to claim 1 , wherein a titanium thin layer is formed on an inner wall of the through hole.

4. The method of manufacturing the heat receiving tile formed of a carbon fiber composite material according to claim 1 , wherein the high heat flux component is a first wall provided in a nuclear fusion reactor.

5. A heat receiving tile formed of a carbon fiber composite material used for a high heat flux component comprising:
a heat receiving block formed of a carbon material and provided with a through hole;
a cooling tube formed of a copper alloy and fitted in the through hole;
a cylindrical material of interlayer disposed between the heat receiving block and the cooling tube;
brazing layers inserted between the material of interlayer and the heat receiving block and between the material of interlayer and the cooling tube; and
a slit formed over a thickness of the heat receiving block and passing through the heat receiving block and the material of interlayer so as to reach the cooling tube.

6. The heat receiving tile formed of a carbon fiber composite material according to claim 5 , wherein a titanium carbide layer is formed on an inner wall of the through hole.

7. The heat receiving tile formed of a carbon fiber composite material according to claim 5 , wherein the high heat flux component is a first wall provided in a nuclear fusion reactor.

8. The method of manufacturing the heat receiving tile formed of a carbon fiber composite material according to claim 2 , wherein a titanium thin layer is formed on an inner wall of the through hole.

9. The method of manufacturing the heat receiving tile formed of a carbon fiber composite material according to claim 2 , wherein the high heat flux component is a first wall provided in a nuclear fusion reactor.

10. The method of manufacturing the heat receiving tile formed of a carbon fiber composite material according to claim 3 , wherein the high heat flux component is a first wall provided in a nuclear fusion reactor.

11. The method of manufacturing the heat receiving tile formed of a carbon fiber composite material according to claim 8 , wherein the high heat flux component is a first wall provided in a nuclear fusion reactor.

12. The heat receiving tile formed of a carbon fiber composite material according to claim 6 , wherein the high heat flux component is a first wall provided in a nuclear fusion reactor.
