The tube 1 and the heat-resistant mat 11 and the electromagnetic coil 12 are glued and fixed.

Since the heat-resistant pad 11 is provided between the electromagnetic coil 12 and the tube 1, when the electromagnetic coil 12 is electrically heated, it is necessary to conduct heat to the tube 1 via the heat-resistant mat 11 as a medium, and the heating rate is slow, resulting in a slow heating. The heating efficiency is poor; and the electromagnetic coil 12 is completely exposed, and in some cases, some of the heat energy is lost, resulting in poor heating efficiency; poor heating efficiency means that the power consumption is relatively high, and in construction disassembly and assembly, Both are time-consuming and laborious, and these shortcomings need to be improved.

The reason is that the main purpose of this creation is to provide an electromagnetic heating coil that can achieve convenient construction, quick assembly, energy saving and improved heating efficiency.

According to the above structural combination, the electromagnetic heating coil 2 of the present invention is disposed on the magnetic conductive tube 6 of the mechanical device, and when energized, the magnetic conductive tube 6 (metal electrical conductor material) is heated by electromagnetic induction, so that The magnetic flux tube 6 generates thermal energy. The electromagnetic coil 4 is completely enclosed by the outer casing 3 due to being disposed in the outer casing 3. The electromagnetic conductive element is shielded from the outer magnetically conductive object to be fixed to the electromagnetic heating. The magnetic flux tube 6 in the ring 2 increases the magnetic field strength and has high heating efficiency; further, the electromagnetic heating ring 2 and the magnetic flux tube 6 have a gap 7 therebetween, so that the electromagnetic induction is converted into the magnetic permeability.
