HEAT EXCHANGER Russian patent published in 2019 - IPC F28D7/02 F28G13/00 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering and can be used in designs of capacitive recuperative heat exchangers of surface type – mainly water-to-water heaters in heat supply and hot water supply systems. Heat exchanger comprises casing with supply and discharge branch pipes of heated circuit, tubular system in the form of coil located in the center of casing, with supply and discharge nozzles of heating circuit, connected to casing, impact assembly is arranged downstream of heating circuit discharge branch pipe and connected with electric drive. Coil is made in the form of a cylinder, to the inlet and outlet of which the pistons are installed, which are installed respectively in the lower and upper chambers. In upper chamber there is also spring.

EFFECT: invention increases heat transfer coefficient in heat exchanger between heating and heated medium, reduces metal consumption of structure, simplifies design and increases effect of self-cleaning of heat transfer surface.
