HYDRODYNAMIC HEAT-GENERATOR FOR HEAT SUPPLY NETWORK Russian patent published in 2018 - IPC F24J3/00 

FIELD: heating system.

SUBSTANCE: hydrodynamic cavitation heat-generator comprises two electromagnetic field sources and two stators from asynchronous electric motors disposed coaxially and counter-currently on a non-magnetic cylinder, to the ends of which a heat accumulator with a heat exchanger included in the heat supply network is connected through the pipeline, and on both sides of the stators current-conducting grids are introduced, connected together and in coordination with the windings of the stators to the corresponding sources of the electromagnetic field. Standard blocks of frequency-controlled drive of electric motors are used as the sources of the electromagnetic field. Between the sources of the electromagnetic field and the stator windings, high-speed winding phase rotation switches are additionally added to increase the efficiency of the heat generator. In the heat generator, a magnetic suspension, technical water or other electrically conductive liquid is used, into which it is expedient to introduce ferromagnetic bodies which are insoluble in this liquid, which increases the sources of cavitation and the thermal energy at the output of the heat generator.

EFFECT: absence of rotating mechanical assemblies, the use of standard series-produced elements and the simplicity of regulating heat and power parameters.
