In order to realize this purpose, the utility model is finished by following measure:
A kind of carbon fiber electrothermal part comprises the heat dissipating layer of the bottom and successively at carbon fiber layer, heat-insulating layer and the shell of last layer.Simultaneously, between carbon fiber layer and heat-insulating layer, cured layer is arranged.This carbon fiber electrothermal part can be tubulose, is through hole in the heat dissipating layer of bottom, and the stream that can supply water passes through, and by heat dissipating layer water is heated.
Further, heat dissipating layer adopting quartz glass or ceramic cloth, cured layer adopts the curing agent of 1200 degrees centigrade of heatproofs, and its main component is water-soluble or inorganic bond, and useful ceramic fiber cloth or ceramic fibre silk siliceous and that the pottery zirconium composition is made distribute wherein.The intensity and the steadiness of carbon fiber layer can be further strengthened in the adding of ceramic fiber cloth or ceramic fibre silk, make it become wear-resisting and have well anti-shearing in, because the existence of silicon and zirconium composition can discharge far ir ray when being heated, further improve the far-infrared effect of carbon fiber electrothermal part simultaneously.
Further, be inserted with the conductive layer and the carbon fiber layer electric connection of electrode, this conductive layer is made by metal molybdenum, has good electric conductivity.
Further, the insulating barrier that around conductive layer, has insulating ceramics to make, this insulating barrier and conductive layer and electrode are all combined closely, and can prevent the infiltration of sky G﹠W.
Further, electrode has one section to be helical form or sheet in conductive layer, can not only increase the surface area of electrode like this, enlarges the intensity that electrical contact surface can also increase electrode.
Further, carbon fiber layer is distributed by wire by carbon fiber, promptly weaves according to weft direction, braiding structure is simple like this, is convenient to operation, also can be by carbon fiber according to parallel and warp direction braiding, braiding can improve intensity like this, makes it more sturdy and durable.
The beneficial effects of the utility model are as follows:
1. the cured layer of this carbon fiber electrothermal part forms one with carbon fiber layer after penetrating into carbon fiber layer, filled up the space between the carbon fiber, the intensity of carbon fiber layer and the ability of anti-shearing force have not only been increased, make its surface become the same with pottery hard and more durable, prolong its useful life, and contain the ceramic fibre silk or the ceramic fiber cloth of further its intensity of raising in this cured layer, and this pottery contains chemical elements such as silicon and zirconium, can further improve its far effect.
2. this carbon fiber electrothermal part is owing to be heater based on the radiation far ir ray, so its electric radiation transfer ratio is higher, can reach more than 70%, far wavelength is between 7-24um simultaneously, it can be absorbed by hydrone and produce the resonance friction effect, realize improving fast the effect of temperature, make that this carbon fiber electrothermal part pyrogenicity is fast, the efficient height.
3. this carbon fiber electrothermal part working temperature is stable, the scope of application is bigger than traditional electrical hot body, can be according to different temperature requirement design powers under the prerequisite that does not change profile, thereby produce different temperature, draw through experiment, this carbon fiber electrothermal part can use 300-900 ℃, the power bracket of 300-900W, and can reach 10000 hours its useful life.
4. this carbon fiber electrothermal part has the advantage of certain anti-dry, generally the metal electric heating body to the water heating can not heat in air ambient, because under dry fire condition because temperature raises outside can not the condition of very fast heat radiation under, shell is burnt out easily.And carbon fiber electrothermal part of the present utility model is owing to adopt resistant to elevated temperatures carbon fiber, and other materials also is resistant to elevated temperatures simultaneously, so the advantage of stronger anti-dry is arranged.
5. adopt the heating material of quartz material, materials such as acid, alkali are had goodish patience, be equivalent to 30 times of acid-proof ceramics, stainless 150 times as innermost layer.
6. this carbon fiber electrothermal part has better energy conservation, with the conventional metals electric heating element mutually specific energy save electric energy more than 20%.
