Embodiment 1

[0062] refer to image 3 , the sandwich structure divertor module of Example 1 of the present invention comprises a pure W layer, a W-Cu transition layer and a pure Cu layer from top to bottom, the height of the pure W layer is 1mm, and the height of the W-Cu transition layer is 5mm , the height of the pure Cu layer is 30mm, and the pure Cu layer is provided with a circular through hole with a diameter of 12mm, which is used to connect to the cooling channel. From the pure Cu layer to the pure W layer, the mass percentage of Cu element is gradually reduced from 100%. to 0, while the mass percentage of W element gradually increased from 0 to 100%.

[0063] The process of integrally forming the sandwich structure divertor module of embodiment 1 by selecting laser melting technology is: using computer 3D design software to establish a three-dimensional model of the sandwich structure divertor module of embodiment 1, and then importing the three-dimensional model into the slicing ...

Abstract

The invention provides a sandwich structure divertor module including an upper layer, a middle layer and a bottom layer from top to bottom in sequence, the upper layer is made of metal A, and the metal A is made of a first wall material which is suitable for plasma, the bottom layer is made of metal B, and a round through hole channel is formed in the bottom layer, and the material selected by themetal B is a heat sink material with high heat conductivity, the middle layer is made of an alloy of the metal A and the metal B from the bottom layer to the upper layer, the mass percent of the metal B is continuously transited from 100% to 0, and the mass percent of the metal A is continuously transited to 100% from 0. The invention further provides a manufacturing method of the integral form of the sandwich structure divertor module. According to the manufacturing method provided by the invention, the integral forming of the upper layer, the middle layer and the bottom layer of the sandwich structure divertor module can be realized, the connection of different layers does not need to be carried out through processes such as welding and the like, so that the manufacturing process and the manufacturing cost are greatly shortened.

Description

technical field [0001] The invention relates to the technical field of first wall materials used in nuclear fusion devices, in particular to a sandwich structure divertor module and a manufacturing method for integral forming thereof. Background technique [0002] Fusion energy generated by nuclear fusion reactions is an important potential way to solve human energy problems. At present, there are two mainstream controllable nuclear fusion solutions: one is laser confinement (inertial confinement) nuclear fusion, magnetic confinement nuclear fusion (tokamak) . Among them, the Tokamak, which uses a strong magnetic field to confine high-temperature plasma, is the most promising device for realizing controllable thermonuclear fusion reactions. Many famous nuclear fusion projects in the world, including the International Thermonuclear Experimental Reactor (ITER) Both the Advanced Superconducting Tokamak Experimental Facility (EAST) use the method of magnetic confinement nuclear...
