INDUCTION HEATING DEVICE OF OIL PRODUCTS Russian patent published in 2014 - IPC H05B6/10 F28D11/02 

FIELD: heating.

SUBSTANCE: device includes an induction heater, a magnetoconductive screen, a heat insulating casing, an induction winding enveloping a cylindrical capacity, an AC rectifier and an inverter connected to the induction winding and an inverter control unit, temperature sensors of inlet and outlet flows, which are connected to a temperature comparator that is connected to the inverter control unit and a pump control unit connected to a pump. It is equipped with a bypass pipe, one end of which is located in cross section of an inlet delivery branch pipe, at the inlet of which the pump is fixed mechanically, and the other end is located in cross section of an outlet suction branch pipe with an automatic shutoff-control element connected to the control unit of the shutoff-control element connected to the temperature comparator. With that, the induction heater is located horizontally; the cylindrical capacity is made from non-magnetic material with a vertical wall installed in liquid flow direction, and the cylindrical element is made in the form of a heat exchange tube from ferromagnetic material, which is located inside the cylindrical capacity with a gap and equipped with horizontal heat exchange rods installed inside the tube in a staggered order, heat exchange semi-spheres located on its outer surface in a staggered order, and a temperature sensor installed on outer surface of the heat exchange tube and connected to the temperature comparator.

EFFECT: simpler heater design and improved reliability and automation of the device operation.
