The cylindrical electromagnetic heating coil disk includes a plurality of magnetic drive ring modules 100, the magnetic drive ring modules 100 are arranged around the outer periphery of the load, and a plurality of the magnetic drive ring modules 100 are sequentially distributed along the length direction of the load. Among them, each magnetic drive ring module 100 includes a plurality of electromagnetic components 200, the plurality of electromagnetic components 200 are arranged around the outer periphery of the load, and each electromagnetic component 200 includes a bracket 210 and an electromagnetic coil 220 wound around the bracket 210. The end face of the electromagnetic component 200 faces the outer peripheral wall of the load.

[0033] Specifically, the cylindrical electromagnetic heating coil disk may further be provided with a housing or a base frame. Each magnetic drive ring module 100 is arranged inside the housing, and the cylindrical load may be a water pipe 300 or a water tank. A plurality of electromagnetic components 200 in each magnetic drive ring module 100 surround the outer periphery of the water pipe 300 or the water tank. Water can flow in the water pipe 300 or the water tank, and a plurality of magnetic drive ring modules 100 may be arranged along the water flow direction. Each magnetic drive ring module 100 can magnetically drive and heat the corresponding area of the load, so that the water flow can be continuously heated.

[0034] The cylindrical electromagnetic heating coil disk of the present utility model can drive and heat a cylindrical load. A plurality of magnetic drive ring modules 100 are sequentially distributed along the length direction of the load. A plurality of electromagnetic components 200 of each magnetic drive ring module 100 are arranged around the outer periphery of the load, and the end face of the electromagnetic component 200 faces the outer peripheral wall of the load. The electromagnetic coil 220 passes through an alternating current, thereby generating an alternating magnetic field.

[0037] By opening the limiting groove 211 on the disk-shaped bracket 210, the electromagnetic coil 220 can be wound in the limiting groove 211 for limiting.
