HEAT EXCHANGER Russian patent published in 2010 - IPC F28D7/00 

FIELD: heating.

SUBSTANCE: in heat exchanger containing the housing with bank of heat exchange tubes fixed in tube sheets, feed water supply tube, feed water header, superheated steam header, electric cable for magneto-hydrodynamic pump, inside straight section of each heat exchange tube there installed is the tube so that heat carrier can enter and leave through it; at that, on it there made are compensation bends located in series along screw line with touch of each bend with external tube on external surface of which there installed are elements-intensifiers the cutouts of which contribute to additional heat carrier swirling in order to increase heat transfer coefficient.

EFFECT: design of heat exchanger of the proposed type allows increasing heat exchange intensity, uniformity of temperature field in cross section of tube bank, operating reliability owing to possibility of decreasing the tube bank length and linear temperature expansions.
