Zusammenfassung:A closed V-shaped acute-angle structure for a first wall of a divertor, including: a target, a reflector plate and a cooling water pipe connected in sequence. The target and the reflector plate both have a flat-plate structure, including a tungsten layer, a copper layer, a chromium-zirconium-copper layer, a stainless-steel layer and a stainless-steel cover plate. The chromium-zirconium-copper layer, the stainless-steel layer and the stainless-steel cover plate are combined to form a heat sink, where the chromium-zirconium-copper layer and the stainless-steel layer are processed to form a HyperVapotron cooling water channel which is communicated with the cooling water pipe to form a cooling water channel. The target and the reflector plate are butt welded to form the closed V-shaped acute-angle structure to enable the flexible adjustment and control of plasma strike points between the target and the reflector plate, enabling the flexible adjustment of the plasma configuration. At a chromium-zirconium-copper side of the heat sink in a welding area, the HyperVapotron cooling water channel experiences a transition in a sequence of the chromium-zirconium-copper layer- chromium-zirconium-copper and stainless-steel mixed layer-stainless-steel layer.
