1. , the electrically heated method of a kind of power frequency, it is characterized in that:

  • when winding is connected alternating current, iron core forms a closed magnetic loop, the eddy electric field that the variation magnetic field produced is acted on the closed metal ring that is sleeved on around the closed magnetic loop cross section, its the inner free electron of closed metal ring that is arranged in the liquid reserve tank forms closed vortex flow and produces heat as heater, its peripheral liquid is heated, and heating power is along with the quantity of closed metal ring, the sectional area of closed metal ring, the variation of the resistivity of the girth of closed metal ring and closed metal ring material and changing.
