Description

A kind of new-type energy-saving carbon fiber electrothermal tube

1, technical field

The utility model relates to a kind of electrical heating elements, specifically a kind of new-type 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 new-type 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, the outer connecting line of power supply 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 carbon fiber electrothermal part is oxidized in heating process.

Accompanying drawing 1 is a kind of structural representation of new-type energy-saving carbon fiber electrothermal tube;

5, embodiment

Explain below with reference to Figure of description a kind of new-type energy-saving carbon fiber electrothermal tube of the present utility model being done.

A kind of new-type energy-saving carbon fiber electrothermal tube that the utility model provides, its structure is by the outer connecting line 1 of power supply, lead brace 2, connection wire 3, external insulation housing 4, center support skeleton 5, carbon fiber electrothermal part 6, external insulation porcelain fixed block 7 constitutes, center support skeleton 1 is fixed in the inner chamber body of carbon fiber electrothermal part 6, connection wire 3 bundles are entangled in the two ends that are arranged on the carbon fiber electrothermal part 6 in external insulation housing 4 inner chambers, connection wire 3, outer connecting line 1 of power supply and lead brace 2 join and are enclosed in admittedly in the termination of external insulation housing 4, and external insulation porcelain fixed block 7 is arranged on the end of external insulation housing 6; Be filled with inert gas 8 in the external insulation housing 6.

A kind of new-type 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 support skeleton adopts random geometry.

The processing and fabricating of carbon fiber is a known technology, and carbon fiber electrothermal part adopts carbon fiber preform and carbon fibre composite; Center support skeleton, external insulation housing external insulation porcelain 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.
