Problems solved by technology

[0004] Although the above-mentioned heating plate has the advantages of small deformation of the heating element, long service life, and not easy to be brittle, but because the skeleton of the heating element is made by pasting the plate on the middle plate core and then pressing it, its strength is low and the heat conduction is low. The power is also unable to fully exert the thermal conductivity of the material due to its structural limitations, and the production process is complicated, and the service life is not stable

Embodiment Construction

[0038] Such as figure 2 As shown, the heating plate in the present invention includes a plate-shaped heating core and protective layers 1 respectively arranged on both sides of the heating core. The heating core includes a heating frame 2 and a heating element installed in the heating frame 2. The heating element is reciprocally wound in an "S" shape and the heating wire 31 installed in the heating frame 2. The power should be set according to the relevant requirements of the national standard and the heating core. , to select the cross-sectional area and winding density of the heating wire 31. The material of the heating wire 31 is preferably a nickel-chromium heating wire, and may also be a heating wire of other materials. The heating wire 31 in this embodiment is a flat wire, and the flat wire is wound in a vertical form at the corner, and gradually transitions to be arranged parallel to the surface of the heating element toward the middle. An insulating pad is added on ...

Abstract

The invention relates to an ultrathin refined ceramic high-thermal-conductivity heating plate. The ultrathin refined ceramic high-thermal-conductivity heating plate comprises a plate-shaped heating core and protective layers arranged on two sides of the heating core respectively, wherein a heating component comprises a heating skeleton and a heating wire embedded into the heating skeleton; and the protective layers are far infrared radiation and high-temperature-resistant waterproof layers. The ultrathin refined ceramic high-thermal-conductivity heating plate has the advantages of high admissible power density, thinness, light weight, high heat-dissipating efficiency and the like. The invention also discloses a manufacturing method for the ultrathin refined ceramic high-thermal-conductivity heating plate.
