INDUCTION ELECTRIC HEATER FOR LIQUID Russian patent published in 1997 - IPC

FIELD: electrical engineering. SUBSTANCE: induction electric heater has body and ferromagnetic many bars core transformer placed in it. Primary winding of transformer is three phases made and connected to alternative voltage power net. Secondary winding serves as heat exchanger and it is made like vessel with bottom input and top output pipes for pass through liquid heating. Vessel has vertical channels with electrically conducting walls for transformer core bars placing inn with insulating separation. EFFECT: higher efficiency factor, lower material expenditure. 3 cl, 1 dwg
