In view of the disadvantages of high frequency heating devices such as low heating efficiency,large power consumption and uneven heating temperature,a new type of high frequency electromagnetic heating device with uniform distribution of temperature field and low power consumption is proposed based on the basic theory of electromagnetic field and the principle of parallel magnetic field co-directional vector superposition magnetic field enhancement.Simulation experiments were conducted to optimize the design parameters,inclu-ding the arrangement of the electromagnetic coils,the number of coil turns,and the interval between the coil and the heating plate.The results indicate that the optimal spacing between the parallel coils is 15 mm,while the ideal distance between the magnetic conductive heating plate and the heating coil is 5 mm.This configura-tion brought about low power consumption and minimized the temperature difference between the center and the edge of the heating area.
