Non-metallic material plane heating device

Abstract

The invention discloses a non-metallic material plane heating device. The non-metallic material plane heating device comprises a heating body assembly and an air duct structure assembly, the heating body assembly is fixed on the air duct structure assembly; the heating body assembly is formed by mixing and blending a non-metal conductive heating material, a high-temperature adhesive and a high-temperature-resistant insulating material according to resistance values; the non-metal conductive heating material comprises graphene and PI carbon fibers, and the heating temperature is higher than 200DEG C; the air duct structure assembly is provided with two conductive silver electrodes which are insulated from each other; the heating body assembly is connected with a conductive silver electrodeof the air duct structure assembly; and the heating body assembly is sequentially provided with an insulation protection layer, a heating layer and an insulation fixing layer. The thickness of the heating layer ranges from 0.001 mm to 1 mm; the adjustable range of the heating temperature of the heating layer is room temperature to 600 DEG C; and the heating body assembly converts electric energyinto heat energy. Air can be in full contact with the heating surface of the non-metal conductive heating material, so that the air speed is higher, and more heat is increased; and the heat conversionefficiency is high, heat loss is small, and energy is saved.

Description

technical field [0001] The invention relates to a heating device, in particular to a non-metal material plane heating device. Background technique [0002] In daily life, equipment such as hair dryers, fan heaters, and electric heaters are inseparable from heating elements. At present, the common hair dryer in the market, its heating element is mainly made of iron chromium wire or nickel chromium wire, the heating efficiency of this kind of heating element is low, easy to oxidize and deform, and the service life is short; iron chrome wire or nickel chrome wire The highest temperature resistance can reach 1100°C, and it is easy to generate open flames when the safety protection fails, and the safety performance is low. [0003] After searching, general surface heating materials and structures, such as patent No. CN200520015978.1, straight cylinder ring type, and straight cylinder air outlet rib type, the air outlet is blown parallel to the heating surface, which cannot effec...
