Background

Industrial electromagnetic heaters are widely used in various industrial processes of heat treatment, such as molding of plastics and rubber, forging of metal devices, production of medical infusion bags and infusion tubes, antifreezing and heating of oil delivery tubes, food processing, recycling of industrial waste materials, even warming in winter, and the like.

The industrial electromagnetic heater is generally composed of two parts, namely a variable frequency host and heating coils, wherein some heating coils are wound on a hearth; the industrial electromagnetic heater is actually a variable frequency heater, a main machine of the industrial electromagnetic heater usually uses 220V or 380V alternating current, the rectified direct current working voltage is 330V or 540V respectively, and then the direct current is converted into the alternating current of 10 kHz-50 kHz through a variable frequency circuit and is output to a heating coil;

the main power device of the main machine is an IGBT module, the working modes are generally three, namely half-bridge, full-bridge and double-machine parallel output, namely two same main machines (which can be half-bridge or full-bridge, and whichever type, the output ends of the two main machines are connected with one or a group of resonant capacitors in series) are used, the output ends of the two main machines are connected to the same heating coil together, and the two main machines simultaneously supply power for one heating coil so as to improve the heating power and the heating temperature;

the heating coil usually uses litz wire, i.e. a large enamelled wire formed by combining a plurality of fine enamelled wires is wound on the outer wall of a hearth, the hearth usually uses an iron material with good magnetic conductivity, and the hearth can be in various shapes such as a flat plate shape, a pot shape, a barrel shape, a pipe shape and the like and is determined by the actual heating requirement; a layer of heat insulation and insulating material such as asbestos and the like is required to be added between the hearth and the litz wire so as to prevent the temperature of the coil from rising due to the fact that the heat of the hearth is transferred to the coil;

litz wire is expensive and the problem of heat dissipation is not easy to solve in high-power working occasions.

The output capacitor is fixed in the heating host, and the capacitance of the output capacitor is a fixed value, so that the heating coil must have certain inductance, namely the output coil lacks flexibility and compatibility, so that one heating system can only heat one hearth, and the cost performance and the utilization rate of the host are greatly reduced.
