METHOD FOR OBTAINING HEAT FOR HEATING BUILDINGS AND STRUCTURES, A HEATING DEVICE FOR ITS IMPLEMENTATION AND AN ELEMENT OF A HEATING DEVICE Russian patent published in 2022 - IPC F24D3/00 F24V40/10 

FIELD: heat engineering.

SUBSTANCE: method for obtaining heat for heating buildings and structures includes pumping the coolant under pressure, eliminating the appearance of cavitation in the coolant flow, in a heating device. The device contains a heat energy generator, a heat transfer system to the consumer connected to each other in a closed circuit by means of supply and return pipelines, at least one circulation pump located in this circuit and at least one recirculation pipeline installed with direct and return pipelines, while the said at least one recirculation pipeline contains at least one element containing a confusor, diffuser and at least one annular groove made between the diffuser and the confusor. The outer part of the element is made of ferromagnetic material, and the inner part of the element at the location of the annular grooves is made of corrosion-resistant material with the possibility of forward and reverse martensitic phase transitions. The inner part of the element outside the annular grooves, confusor, diffuser is made of paramagnetic material, while the annular groove is made in the annular element.

EFFECT: increase in the efficiency of heat generation due to the stabilization of magnetic fluxes in the required direction, which eliminates the appearance of eddy currents opposing the flow of liquid.
