Abstract
The utility model provides a novel energy saving carbon fiber electric-heat tube consisting of a power supply leading wire, a leading wire connecting sheet, an internal connecting wire, a fixed core, an outer insulating shell, a central inner support, a flexible carbon fiber electric-heating element, and an outer insulating porcelain fixed block and the inert gas. The flexible carbon fiber electric-heating element is twined on the central inner support; the both ends of the flexible carbon fiber electric-heating element are fixed inside the inner cavity of the external insulating shell by the fixed core; the internal connecting wire is twined on the both ends of the flexible carbon fiber electric-heating element, the internal connecting wire and the power supply leading wire are connected with the leading wire connecting piece and heated and sealed inside an end of the external insulating shell; the external insulating porcelain fixed block is arranged on the end of the external insulating shell. Compared with the prior art, the carbon fiber electric heating element of the utility model has the advantages of rational design, simple structure, easy processing, easy use, high heat efficiency, long life length, wide temperature range and wide range of application, thereby having the very good popularization and use value.
Description
1, technical field
The utility model relates to a kind of electrical heating elements, specifically a kind of energy-saving carbon fiber electrothermal tube.
2, technical background
As everyone knows, the quartz ampoule electric heater of prior art mostly uses materials such as nichrome, carbon fiber non-woven mat, molybdenum filament, tungsten filament 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 materials such as general nichrome, molybdenum filament, tungsten filaments, electric heating element is easily oxidation of surface in the electric heating use, cause local overheating easily and be blown, have visible light to exist simultaneously in the electric heating process, so the heat efficiency is low.The carbon fiber non-woven mat is short useful life, easily pollutes the quartz ampoule inner chamber.Though above-mentioned thermo electric material has the application of broad, but since they be difficult to be made into and not only use the anti-permanent but also high electric heater of the heat efficiency and influenced its range of application to a certain extent.
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 are wide, the course of work does not have visible light and with a kind of energy-saving carbon fiber electrothermal tube of Far-infrared Heating.
The purpose of this utility model realizes in the following manner, adopt carbon fiber bundle, carbon fiber preform and carbon fibre composite to replace common nichrome, carbon fiber non-woven mat, molybdenum filament, tungsten filament material to make heater, carbon fiber exothermic part twines or attached on the inner support of center, power lead is connected with the end of carbon fiber exothermic part from the two ends of external insulation housing inner chamber respectively by lead brace, connection wire.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 flexible carbon fiber electrothermal part is oxidized in heating process.
4, description of drawings
Accompanying drawing 1 is a kind of structural representation of energy-saving carbon fiber electrothermal tube;
5, embodiment
Explain below with reference to Figure of description a kind of energy-saving carbon fiber electrothermal tube of the present utility model being done.
A kind of energy-saving carbon fiber electrothermal tube of the present utility model, its structure is by power lead 1, lead brace 2, connection wire 3, fixed core 4, external insulation housing 5, center inner support 6, flexible carbon fiber electrothermal part 7, external insulation porcelain fixed block 8 and inert gas 9 constitute, flexible carbon fiber electrothermal part 7 is wrapped on the center inner support 6, the two ends of flexible carbon fiber electrothermal part 7 are fixed among the inner chamber of external insulation housing 5 by fixing central layer 4, connection wire 3 bundles are entangled in the two ends of flexible carbon fiber electrothermal part 7, connection wire 3, power lead 1 joins with lead brace 2 and is enclosed in admittedly in the termination of external insulation housing 5, and external insulation porcelain fixed block 8 is arranged on the end of external insulation housing 5; Be filled with inert gas in the external insulation housing 5.
A kind of its processing and fabricating of energy-saving carbon fiber electrothermal 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 center inner support can adopt random geometry.
The processing and fabricating of carbon fiber is a known technology, and flexible carbon fiber electrothermal part adopts carbon fiber bundle, carbon fiber preform and carbon fibre composite; Center inner support, external insulation housing and external insulation fixed block are to be made by exotic materials such as inorganic insulating material or quartzy class glass insulating materials; The lead brace is made by molybdenum sheet.
The advantage of the carbon fiber electrically thermal 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 between 20W/cm2-40W/cm2, and 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.
