Embodiment 1

[0027] Electromagnetic heating constant temperature infusion tube section structure diagram figure 1 As shown, wherein: 1 is an aluminum oil pipeline, 2 is a magnetic material with a Curie point temperature of 105 degrees, 3 is an insulation material, 4 is a high-frequency electromagnetic induction coil, and 5 is a polyurethane heat preservation material. When the alternating current passes through the high-frequency electromagnetic induction coil 4, the coil 4 generates an alternating magnetic field. When the magnetic field lines in the alternating magnetic field pass through the magnetic material 2, countless small eddy currents are generated on the surface of the magnetic material 2, and the magnetic material 2 itself generates heat at high speed. When the temperature of the magnetic material 2 is higher than the Curie point temperature of 105 degrees, the magnetic material 2 loses its magnetism, and the heating stops. When the temperature of the magnetic material 2 is lower...
