Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Step 1. Raw material preparation for cooling plate processing

[0038] Step 1.1: The length, width and thickness of the raw material are 800mm, 80mm and 7mm respectively, the flatness of the raw material is required to be 0.1mm, and the direction of the flow channel is the length direction of the raw material;

[0039] Step 1.2: If figure 1 As shown, it is divided into two pieces A and B along the direction of the flow channel. After cutting, the length of each piece along the direction of the flow channel is 400mm;

[0040] Step 2. EDM drilling

[0041] Step 2.1: Fix raw materials A and B on the fixture respectively;

[0042] Step 2.2: If figure 2 As shown, a numerical control electric spark punching machine is used to drill holes in A and B sequentially along the flow channel arrangement direction. The punching position...

Abstract

The invention relates to the design technology of an international thermonuclear fusion experimental reactor, and particularly discloses a processing and manufacturing method of an ultra-long ultra-fine special-shaped multi-channel cooling plate. After raw materials for cooling plate processing are prepared, holes are drilled by electric sparks. Then a special-shaped channel is cut, and a rectangular strip is welded. Each of the raw material plates processed blind holes are welded into a whole plate. And drilling again by the electric spark, a molybdenum wire is passed through the through holes, the centers of small holes are taken as dead centers, and the small holes are cut into square holes with flow channels of 2.5 mm in length and 4.5 mm in width. The welding method and nondestructivetesting adopted in the processing technology are simple, easy to operate, the processing quality of the ultra-long ultra-fine special-shaped multi-channel cooling plate is effectively ensured and theprocessing success rate is improved.

Description

technical field [0001] The invention relates to the design technology of the International Thermonuclear Fusion Experimental Reactor, in particular to a processing and manufacturing method for an ultra-long ultra-fine special-shaped multi-channel cooling plate. Background technique [0002] The Tritium Breeder Module (TBM) is a key component of the International Thermonuclear Experimental Reactor (ITER), and an experimental module for which all countries participating in ITER enjoy independent intellectual property rights. Its main goal is to verify the tritium production capacity and heat carrying capacity, and provide important technical support for the design of the nuclear island of the future fusion power plant. At present, the European Union, India, South Korea, Japan and other countries are actively developing their own tritium breeding blanket modules. After technology screening, China decided to develop the Chinese solid-state breeding blanket module (HCCBTBM). [...
