HEATER Russian patent published in 2012 - IPC F24J3/00 B82B1/00 

FIELD: power industry.

SUBSTANCE: proposed heater consists of housing, rotor located in it and provided with screw delivery grooves and return grooves, the direction of which is opposite to delivery ones, and made on the rotor; in addition, housing on internal surface is equipped with three-phase winding and has electric current supply wires to three-phase winding. Rotor is rigidly connected by means of a seal to housing and made from non-magnetic material: copper, bronze, brass, aluminium or silumin, has central hole for air ventilation, and cavity between internal surface of housing and external surface of rotor is filled with transformer oil to which there introduced are nanoparticles of carbonyl iron with the size of 10 to 15 nanometres in quantity of 3-16 volume percents of transformer oil volume and covered with surface active substance and oleinic acid.

EFFECT: creation of the device capable of intense warming of heat carrier with rotating magnetic field.
