Embodiment Construction

[0030] Below in conjunction with accompanying drawing, specifically illustrate the present invention:

[0031] Such as figure 1 with figure 2 Shown are the plate and tube structures of a carbon fiber electric heating body of the present invention, including the bottom heat dissipation layer (1) and the carbon fiber layer (2) on the upper layer, heat insulation layer (4) and The casing (5), the electric heating body is in the shape of a tube or a plate, and of course it can also be in any other shape. If the carbon fiber electric heater is tubular, there will be a through hole (6) in the heat dissipation layer (1) at the bottom, which can allow water to pass through and heat the water through the heat dissipation layer (1). The heat dissipation layer (1) is made of quartz glass or ceramic cloth.

[0032] image 3 It is a B-B cross-sectional view of a tubular structure of a carbon fiber electric heating element in the present invention, and there is a solidified layer (3) b...

Abstract

The invention relates to a carbon fiber electrothermal element, which comprises a radiating layer at the lowest layer and also comprises a carbon fiber layer, a solidifying layer, a heat insulating layer and an outer housing arranged on the upper layer in sequence. The radiating layer is made of quartz glass or ceramic cloth. The solidifying layer adopts a curing agent resistant to a temperature up to 1200 DEG C and is mainly composed of a soluble adhesive, wherein ceramic fiber cloth or ceramic cellosilk prepared by ceramics containing silicon and zirconium components is distributed among the soluble adhesive. The strength and the anti-sheering force of the carbon fiber layer of the carbon fiber electrothermal element are enhanced, the surface becomes hard and durable as ceramics, the service life is prolonged, the solidifying layer contains ceramic fiber wires or ceramic fiber cloth which can further enhance the strength of carbon fiber electrothermal element, and in addition, the ceramics contains chemical elements, such as silicon, zirconium, and the like, and can further enhance the far infrared effect.

Description

technical field [0001] The invention relates to an electric heating body, in particular to an electric heating body used for heating electrical equipment. Background technique [0002] In the prior art, electric heaters for heating mostly use metal wires such as molybdenum wires, tungsten wires, etc. as electric heating elements. However, during the electric heating process of the metal heating element, due to the high temperature, the surface is easily oxidized, which leads to problems such as burning and damage of the heating element. This not only shortens its service life, reduces its thermal efficiency, and consumes a lot of energy, but also easily causes the circuit to catch fire. Therefore, it is difficult to manufacture a durable electric heater with high thermal efficiency from the above-mentioned metal materials, which affects the application range of the electric heater to a certain extent. In recent years, quartz glass coated on the outer surface has appeared t...
