COOLED TOKAMAK WALL Russian patent published in 2020 - IPC G21C15/00 F16L59/07 

FIELD: physics.

SUBSTANCE: invention relates to tokamak cooled wall. Wall includes heat flow receiving surface [1] and heat-conducting zone adjoining it [2], together with casing [3] forming steam collection cavity, needle heat-conducting elements [4] located perpendicularly to heat-conducting zone [2] and having thermal contact with it. Needle-shaped heat-conducting elements [4] form rows. All even elements in even row are made hollow [5] and in lower part have jet sprayers [6], and in upper part hollow elements [5] are connected by individual pipelines [7] with group pipeline [8] of water supply. Heat flux emitted by the high-temperature plasma is received by the heat flow reception surface 1 and, due to heat conductivity of the material of heat-conducting zone 2, heats the needle heat-conducting elements 4 in casing 3, including hollow elements 5, to which water is supplied via individual pipelines 7 from group pipeline 8. Perpendicular arrangement of needle heat generating elements 4 and hollow elements 5 increases efficiency of heat removal from heat flow receiving surface 1. Note here that heat flow receiving surface 1 and heat-conducting zone 2 have maximum temperature.

EFFECT: increased efficiency of tokamaks walls cooling with high intensity of emitted heat flow.
