Abstract
The utility model relates to an electromagnetic induction heating system, and belongs to the technical field of heating systems. The electromagnetic induction heating system comprises a metal core. An outer wall of the metal core is covered with a thermal insulation layer. The thermal insulation layer is sleeved with an electromagnetic heating coil. Two ends of the electromagnetic heating coil are connected to a controller. According to the utility model, the electromagnetic induction principle is adopted. A workpiece to be heated is a secondary coil. After being energized, the workpiece to be heated is subjected to thermal expansion from inside to outside under the effect of induction current so that the needs of interference fit are met. By means of internal thermal heating, internal molecules of a heating body produce heat through direct induction of magnetic energy, and the average warm-up time is reduced by 1/2, compared with a resistance coil heating method. Meanwhile, electric-thermal energy conversion efficiency is over 98%, which means, under the same condition, the electromagnetic induction system saves as much as 70-90% of electric power compared to a resistance coil for heating. The heating part employs a cable structure. Since a cable itself does not generate heat and has a long service life, regular maintenance and replacement of heating coils, which the resistance coil heating method requires, are avoided and almost no costs are needed for later maintenance. The electromagnetic induction heating system has good application prospects.
