The connecting wire is bundled and wound at both ends of the carbon fiber electric heating body, and the connecting wire, the power supply connecting wire, and the connecting sheet of the conducting wire are connected and are sealed in the end head of the external insulation shell body. The porcelain insulating fixing block is arranged at the end part of the external insulation shell body. The carbon fiber electric heating element of the utility model has the advantages of reasonable process design, simple structure, easy manufacture, convenient use, high heat efficiency, long service life, wide usage temperature range, broad application range, etc.
Description
1, technical field
The utility model relates to a kind of electrical heating elements, specifically a kind of new-type carbon fiber electric heating tube.
2, technical background
As everyone knows, the electric heater of prior art mostly uses nichrome, molybdenum filament, tungsten filament material to do electric heating element.Owing to the reason of these electric heating element materials self inherent characteristic in use has a lot of deficiencies, the electric heating element of making as general nichrome material, molybdenum filament, tungsten filament material, easily oxidation of surface in the electric heating use causes local overheating thus and is blown, and useful life is short.Have visible light to exist simultaneously in the electric heating process, so the heat efficiency is low.Though above-mentioned thermo electric material has the field of the application of broad, use anti-permanent and heat efficiency height and influence its range of application but they are difficult to be made into.
3, summary of the invention
That the purpose of this utility model provides is simple in structure, long service life, electric conversion efficiency height, operating temperature range is wide, the course of work does not have visible light a kind of new-type carbon fiber electric heating tube.
The purpose of this utility model realizes in the following manner, adopt carbon fiber bundle, carbon fiber knit band to replace common nichrome, molybdenum filament, tungsten filament material to make heater, carbon fiber exothermic part twines or attached on the insulator, power lead is connected with the end of carbon fiber exothermic part from the two ends of external insulation housing inner chamber respectively by connecting line.Be locked at last among the external insulation housing of making by quartzy class glass insulating material.The surface of insulation shell is provided with bleeding point outside, so that extract the gas in the external insulation housing out the formation vacuum, charges into inert gas again, prevents that carbon fiber electrothermal part is oxidized in heating process.
4, description of drawings
Accompanying drawing 1 is a kind of structural representation of new-type carbon fiber electric heating tube;
Accompanying drawing 2 is the structural representation of carbon fiber electrothermal part.
5, embodiment
Explain below with reference to Figure of description a kind of new-type carbon fiber electric heating tube of the present utility model being done.
A kind of new-type carbon fiber electric heating tube of the present utility model, its structure is by power lead 1, lead brace 2, connecting line 3, fixed head 4, insulator 5, carbon fiber electrothermal part 6, external insulation housing 7 and porcelain insulating fixed block 8 constitute, carbon fiber electrothermal part 6 is wrapped on the insulator 5, the two ends of carbon fiber electrothermal part 6 are fixed among the inner chamber of external insulation housing 7 by fixed head 4, connecting line 3 bundles are entangled in the two ends of carbon fiber electrothermal part 6, connecting line 3 joins with power lead 1 and lead brace 2 and is enclosed in the termination of external insulation housing 7, and porcelain insulating fixed block 8 is arranged on the end of external insulation housing 7.The centre of carbon fiber electrothermal part 6 is provided with interior insulator 9.Be filled with inert gas in the external insulation housing 7.
A kind of its processing and fabricating of new-type carbon fiber electric heating tube of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
The processing and fabricating of carbon fiber is a known technology, and electric heating element can use polypropylene hydrogen base carbon fibre or asphalt base carbon fiber to make; Insulator and external insulation housing are to be made by exotic materials such as inorganic insulating material and quartzy class glass insulating materials; The lead brace is made by molybdenum sheet.
The advantage of the Carbon Fiber Electric Heating Element that this use is novel is:
1, structural design is simple;
2, thermo-lag is little, quick heating. Heating temp is even;
3, surface temperature is at 500 ℃-900 ℃; Surface heat power is at 20W/cm
2-40W/cm
2Between, the technical parameter range of variation is wide;
4, the geometry range of variation is wide, therefore in actual application, can adopt standard or non-standard unit mode use;
5, electric property is stable, reliable, and useful life is up to more than 10000 hours.
6, applied environment: can be in water, use in the air.Industry can be applied in widely, agricultural, air heat of civil area or the like.
Thereby carbon fiber electrically thermal element of the present utility model is compared with prior art, have the heat efficiency up to more than 98%, at random usability strong, can be made into advantages such as random geometry, structure and production technology are simple.The scope of application is wide.Also have reasonable in design, simple in structure, be easy to processing, easy to use, characteristics such as the heat efficiency is high, long service life, serviceability temperature wide ranges and applied range.Thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
