PROCESS OF HEAT PICK-UP FROM SURFACE OF ENERGY RECEIVER OF DIVERTER OF THERMONUCLEAR REACTOR Russian patent published in 1994 - IPC

FIELD: thermonuclear fusion. SUBSTANCE: molten metal filling agent is pumped through clearances with spiral inserts between pipes cooled with water and inner walls of tubular elements forming panel of energy receiver. Longitudinal speed of pumping through of molten metal filling agent is selected from condition , where δ is width of clearance, d is diameter of pipes with water; r c and l are accordingly density, specific heat and thermal conductivity of molten metal filling agent; h is lead of spiral insert. With realization of above stated condition heat flow coming to energy receiver will be received by pipe not only from side facing plasma but from opposite side too. Thanks to it value of surface of pipe receiving heat will almost double which results in equalization of temperature field in pipe and in tubular element which will lead to decrease of temperature stress. EFFECT: prolonged service life and enhanced reliability of structure of energy receiver of DIVERTER. 2 dwg
