HEAT EXCHANGER Russian patent published in 2011 - IPC F28F1/40 F28D7/16 

FIELD: power industry.

SUBSTANCE: heat exchanger contains housing having external and internal cylindrical walls connected to each other by means of radial partitions forming through-type chambers with formation of continuous circulation circuit, heat exchange plates located inside the chambers and end covers one of which has an inlet opening and the other one has an outlet opening. Internal wall of the housing is made in the form of central insert with heat exchange element located in it; inlet opening is located coaxially to central insert. Radial partitions and heat exchange plates are fixed by means of inner ends in longitudinal slots made on external surface of central insert, and their outer ends are bent along circular arc and enclosed in the housing; at that, housing is equipped with heat exchange jacket. Radial partitions and heat exchange plates are equipped with longitudinal expansion joints.

EFFECT: heat exchange intensification in heat exchanger at simplification of its manufacture and increase in its operational life at complete use of the whole volume of heat exchanger; enlarging functional capabilities of the device.
