Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the eddy current heater of the present invention includes a thermal insulation case 1 for controlling the temperature of the outer case while preventing the temperature from being diffused outward; a ceramic disc 4 is arranged in the heat-insulating shell 1, and a plurality of first through holes are formed in the ceramic disc 4, so that air can flow conveniently and heat can be transmitted; 17 high-temperature-resistant conductors 3 are arranged on the ceramic disc 4, as shown in fig. 2, the low-resistance coil 2 is wound on the high-temperature-resistant conductors 3, the total resistance of the low-resistance coil 2 is further reduced in a parallel connection mode, the low-resistance coils are mutually independent, and the single failure does not influence the overall use; the high-temperature-resistant conductor 3 is provided with a second through hole which is communicated with the first through hole, so that heat transmission is facilitated; the electric cabinet 15 is arranged on the heat preservation shell 1 and used for identifying the heating temperature of the heater and performing safety protection, when the heat is too high, the heating amount is reduced in a power reduction mode, and when a fault occurs, the power-off alarm is performed.
The working principle and the working process of the invention are as follows: as shown in fig. 1-2, when an alternating current passes through a low resistance coil 2, an alternating magnetic field is generated, a current eddy effect is generated on a high temperature resistant conductor 3, and the higher the eddy power is, the faster the high temperature resistant conductor 3 generates heat; the effect can be utilized to enable the high-temperature-resistant conductor 3 to generate huge heat within a short time, and a large-area small-unit uniform distribution mode is adopted, and a plurality of independent heating elements with the same power are uniformly distributed on the surface of the ceramic disc 4, so that uniform and continuous heating is realized.
