INDUCTION ELECTROMAGNETIC COAXIAL LABYRINTH HEATER FOR LIQUIDS Russian patent published in 2016 - IPC H05B6/10 

FIELD: electrical engineering.

SUBSTANCE: induction electromagnetic coaxial labyrinth heater for liquids is designed to be used in electrical engineering and power engineering. Device has a sealed housing-magnetic conductor with bottom (1) and a cover, branch pipe (4) of supply and discharge of the heated liquid, electrically insulated electric coil (3), central pipe (7) of discharge-supply of the liquid with holes at the top end. Vertically on the bottom there is core (2) of the magnetic conductor with a cylindrical cavity and holes in its wall at the lower end. Electrically isolated electric coil is installed on the bottom. Housing-magnetic conductor is made able to disengage from the bottom together with the cover tightly adjacent to the upper end of the magnetic conductor core.

EFFECT: invention provides wider field of use of the device for heating a wide range of liquids with different specific electric resistance, reduced expenditures for electric power and operation, higher efficiency.
