ELECTRIC INDUCTION FLOW HEATER Russian patent published in 2025 - IPC H05B6/10 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and is intended for flow heating of flowing liquids, including high-temperature heat carriers with heating temperature of up to 300 °C. Electric induction flow heater contains a ferromagnetic core, on vertical rods of which there is a primary winding connected to an alternating current source, and a secondary winding located around the primary winding and made in the form of tubular turns of electrically conductive material covering the core rods. Adjacent tubular turns located in one horizontal plane are tightly connected to each other, and extreme of them are connected to one and the second vertical collector pipes, between which on tubular turns located in parallel horizontal planes the heated liquid flows, which is supplied to and discharged respectively through inlet and outlet nozzles. In the first and second collector pipes, blind transverse partitions are installed at a height that increases alternately in the first collector pipe and in the second collector pipe so that the collector pipes are divided into compartments by partitions, to each of which the specified number of tubular turns is connected for successive alternation of passages of all heated liquid in direct and opposite directions.

EFFECT: increased efficiency of liquid heating and increased reliability of the device by increasing the flow rate of the heated liquid and reducing heat losses.
