We present the results of experimental investigations of heat exchanging in a cylindrical tube heated on one side by beams of charged particles (electrons) with a high density of thermal energy. Heat removal is made by a water stream, twisted by a screw insert, having the mass velocities in the range ρw = 187O-8900 kg/(m{sup}2·sec). The experiments were carried out on a fragment of the tube in the receiver of the beams of deviated ions in the system of injection of a T-15 tokamak. The bank of experimental data includes 510 points. It is shown that under the conditions of heat removal by the twisted flow with the coefficient of twisting k = 0.897 and subcooling ～170℃ the density of the flux removed can attain 100 MV/m{sup}2 in the case of long-pulse heating. It is noted that with the number of cycles of about 70 the fatigue destruction of the surface occurs.
