The electromagnetic heater is a novel heating device which converts electric energy into heat energy by utilizing the electromagnetic induction eddy current heating principle. The electromagnetic coil is arranged in the heater, and after the electromagnetic coil is electrified, the electromagnetic coil generates a high-speed changing magnetic field to act on the metal pipe to generate vortex, so that the metal pipe automatically generates heat at a high speed, and the fluid flowing through the metal pipe is heated; because the electromagnetic coil does not generate heat, and almost all the energy converted by the current flowing through the coil is used for heat conversion, the energy loss is very small, the electrothermal conversion rate is as high as 98 percent, the energy-saving effect is more than 50 percent higher than that of the traditional technology, and because the electromagnetic coil does not contact with the rod body metal, the danger of short circuit and electric leakage is avoided, thereby really achieving the purposes of energy saving, safety and reliability.
The electromagnetic induction eddy current generates heat, and the electric energy is converted into heat energy to heat the material to be heated. During operation, low-temperature fluid medium enters an input port of the electromagnetic heating container under the action of pressure through a pipeline, an electromagnetic coil is arranged in the heater along a specific heat exchange flow channel in the electromagnetic heating container by utilizing a path designed by the fluid thermodynamic principle, and after the electromagnetic coil is electrified, the electromagnetic coil generates a high-speed changing magnetic field to act on the metal pipe to generate vortex so as to enable the metal pipe to automatically generate heat at a high speed, so that the temperature of the fluid medium flowing through the metal pipe is increased, and a high-temperature medium required by the process is obtained at an outlet of. The internal control system of the electromagnetic heater automatically adjusts the output power of the electromagnetic heater according to the signal of the temperature sensor at the output port, so that the temperature of the medium at the output port is uniform; when the heating element is over-temperature, the independent overheating protection device of the heating element immediately cuts off the heating power supply, thereby avoiding the heating element from burning out due to coking, deterioration and carbonization caused by over-temperature of the heating material, and effectively prolonging the service life of the electric heater.
