HEAT EXCHANGER Russian patent published in 2013 - IPC F28D7/02 F28F9/24 F28G7/00 

FIELD: power engineering.

SUBSTANCE: in a heat exchanger comprising a jacket with supply and drain nozzles, with a tubular system fixed inside, with supply and drain nozzles, damping-elastic elements and an impact unit, the tubular system is made of two and more coil pipes with rectilinear initial and end sections, the impact unit is made with an outlet channel, with a yoke having a rocking axis: and inlet channels with dart valves on stems in the quantity of coil pipes, each of inlet channels is connected with the outlet channel via dart valves arranged on stems in them as capable of reciprocal movement between channels of inlet and the channel of outlet of the impact unit, and joined with arms of the yoke installed with the rocking axis in the outlet channel of the impact unit, rectilinear initial sections of coil pipes of the tubular system are connected to the supply nozzle of the tubular system via damping-elastic elements, and rectilinear end sections of the coil pipes are connected to the appropriate channels of the impact unit inlet.

EFFECT: higher energy efficiency of a heat exchanger by intensification of heat transfer, reduced metal intensity and increased overhaul period of operation.
