Description

technical field [0001] The invention relates to the technical field of electromagnetic heating, in particular to a multi-stage serial high-efficiency liquid electromagnetic heating system. Background technique [0002] The principle of electromagnetic heating is to generate an alternating magnetic field through an electronic controller and an electromagnetic induction coil. When a container containing ferromagnetic metal components is placed in a suitable position in the coil, the ferromagnetic metal atoms in the container cut the alternating magnetic field lines to make the iron in the container Magnetic metal atoms generate alternating current (ie, eddy current), and the eddy current makes the internal ferromagnetic metal atoms move at high speed and irregularly, and the atoms collide and rub against each other to generate heat energy. [0003] In the prior art, high-power liquid electromagnetic heating systems mostly adopt modularized electromagnetic heating units to be h...

Problems solved by technology

In multiple sets of parallel units, the positions and pipe diameters of the liquid pipelines of the heating bodies of each set of electromagnetic heating units are different, which will cause the pressure and pipeline path between each set of electromagnetic heating units to be different, resulting in the liquid flow distribution of each set of heating devices. Unevenness may cause the heat exchange output capacity of the heating unit with a small flow rate to be low, resulting in local overheating or even local dry burning, which will affect the service life of the electromagnetic heating system

If you want to overcome this problem, you need to make a lot of improvements in the flow and pressure control of the pipeline, which is costly and not conducive to manufacturing; when multiple heating units are connected in parallel, each group needs to work at the same time or stop at the same time during heating operation; If energy-saving operation is to be realized, the power of each heating system needs to be adjustable and the output power should be adjusted synchronously, which is difficult to achieve, the system complexity is high, and the manufacturing cost is also high
