The utility model is achieved in that a kind of high-frequency electromagnetic induction heater coil disc, the lead, ferrite magnetic stripe and the coil disk body that comprise the multiply mutually insulated, some grooves are arranged on the upper surface of coil disk body, the lead embedding is in groove, its special character is: described groove is and equidistantly distributes, or by inner ring the closeest~~gradually dredge~~middle the thinnest~~gradually close~~the close again mode in outer ring distributes; Working power is 50 ± 15KHZ.
Described high-frequency electromagnetic induction heater coil disc, its special character is: described ferrite magnetic stripe is shape linearly, is installed on the lower surface of coil disk body, is radially radially distributed by the center of circle; Described ferrite magnetic stripe is divided into long magnetic stripe, short magnetic stripe, and described long magnetic stripe radially radially distributes at interval with short magnetic stripe, long magnetic stripe by the center of coil disk body stretch out, short magnetic stripe by the coil disk body radially in the middle part of stretch out.
Described high-frequency electromagnetic induction heater coil disc, its special character is: lead twines 20 ± 3 circles on the coil disk body, average diameter 110 ± 10mm, inductance value are 50 ± 15 μ H.
A kind of high-frequency electromagnetic induction heater coil disc, the lead, the coil disk body that comprise the multiply mutually insulated, its special character is: the coil disk body some grooves that equidistantly distribute are arranged or have inner ring the closeest~~gradually dredge~~middle the thinnest~~gradually close~~the close again mode grooves distributed in outer ring, the lead embedding is in groove; Lead twines 20 ± 3 circles at the coil disk body, and average diameter 110 ± 10mm, inductance value are 40 ± 10 μ H; Working power is 50 ± 15KHZ.
The utility model high-frequency electromagnetic induction heater coil disc, owing to adopt such structure, the one, be applicable under the frequency of 50 ± 15KHZ and work, utilize high-frequency induction to heat to being heated vessel, so heat efficiency height.The 2nd, the coil panel number of turn is few, amount of copper consuming is few, D.C. resistance is little, has reduced loss, has improved the heat efficiency, has saved the energy, has reduced cost.The 3rd, the coil panel magnetic gap is even, magnetic circuit brief, also can effectively reduce electromagnetic radiation disturbs, and has reduced electromagnetic pollution.The 4th, coil twine by inner ring the closeest~~gradually dredge~~middle the thinnest~~gradually close~~the close again mode in outer ring, overcome the effect of proximity effect, reduced the caloric value of coil panel middle part, the magnetic field of generation is more balanced, makes to be heated vessel and to be heated more even.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Embodiment 1
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, shown in, a kind of high-frequency electromagnetic induction heater coil disc, the lead (not drawing among the figure), ferrite magnetic stripe and the coil disk body 1 that comprise the multiply mutually insulated, coil disk body 1 has some grooves 11, and the lead embedding is in groove 11, and described groove 11 is and equidistantly distributes, described ferrite magnetic stripe is radially radially distributed by the center of circle, and described ferrite magnetic stripe is shape linearly.Working power is 50 ± 15KHZ.
Long magnetic stripe embedded groove 13, short magnetic stripe embedded groove 12 are arranged on the lower surface of coil disk body 1; Described ferrite magnetic stripe is divided into long magnetic stripe 21, short magnetic stripe 22, long magnetic stripe 21 is installed in the long magnetic stripe embedded groove 13, short magnetic stripe 22 embeds in the short magnetic stripe embedded groove 12, described long magnetic stripe 21 radially radially distributes at interval with short magnetic stripe 22, long magnetic stripe 21 by the center of coil disk body 1 stretch out, short magnetic stripe 22 by coil disk body 1 radially in the middle part of stretch out.When lead passes through high-frequency current, in coil panel, produce alternating magnetic fields.The magnetic stripe guiding magnetic field that is positioned at coil disk body bottom passes through in itself, and long magnetic stripe direction center is to the magnetic field at edge, and the magnetic field at edge is arrived at short magnetic stripe guiding middle part, has shortened the distance of air-gap, has reduced the radiation of magnetic field to the coil panel bottom.
