Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic heaters, and in particular relates to an electromagnetic induction coil cooling structure of an electromagnetic heater. Background Art

[0002] Electromagnetic heating technology has been widely used in various fields of industrial heating. The working principle of electromagnetic induction heating is mainly based on Faraday's law of electromagnetic induction. Its core is to use the electromagnetic induction phenomenon to convert electrical energy into heat energy: when an alternating current passes through an induction coil, an alternating magnetic field is generated, which generates eddy currents within the conductor placed within it. When the eddy currents flow within the conductor, the electrons in the conductor accelerate and generate heat. Compared with other heating methods, this heating method can be connected to high voltage electricity, has a faster heating rate, stronger temperature control ability, and avoids direct contact with the heating medium. In high-voltage working environments, electromagnetic heating technology can eliminate the cost of transformers compared to resistance heating, significantly reducing equipment costs.

[0003] The electromagnetic induction heater cannot dissipate heat and cool the electromagnetic induction coil well during use, which causes the temperature of the electromagnetic induction coil to rise and affects the service life of the electromagnetic induction coil. For this reason, we propose an electromagnetic induction coil cooling structure for the electromagnetic heater. Utility Model Content
