FIELD: electricity.

SUBSTANCE: vortex induction heater comprises magnetic conductor reservoir of cylindrical shape with input nozzle of liquid or gas coolant supply and output nozzle for drain of this coolant, and induction winding of copper wire enclosed into sealed toroid cylindrical vessel of insulating material. At the same time inside specified reservoir there are metal pipes attached as concentrically arranged relative to each other with identical gap to form labyrinth-like passage for specified coolant in direction from inlet nozzle to outlet nozzle, and induction winding is arranged inside specified pipes. The second version of heater provides for fixation of reservoir on frame, to which ribbed pipe of coil type is fixed, one end of which is connected to inlet nozzle of reservoir, and its other end is connected to output nozzle of this reservoir, or pipes ribbed with plates and connected parallel to each other and to inlet and outlet nozzles.
