Description
1, technical field
The utility model relates to a kind of electrical heater element, specifically a kind of carbon fiber electrically thermal element.
2, technical background
As everyone knows, the electric heater of prior art mostly uses nichrome, Aludirome 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, Aludirome material, electric heating element is easily oxidation of surface in the electric heating use, is taken aim at into local overheating and is blown by A, 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
The purpose of this utility model provides a kind of simple in structure, long service life, electric conversion efficiency height, operating temperature range is wide, the course of work does not have visible light carbon fiber electrically thermal element.
The purpose of this utility model realizes in the following manner, adopt weaving carbon fiber bundle, carbon fiber knit band to replace common nickel alloy material to make heater, utilize wire to be processed into the spiral skeleton and on the spiral metal wire skeleton, be with inner insulating layer, carbon fiber exothermic part twines or attached on the spiral skeleton of being with inner insulating layer, power lead is connected with the end of carbon fiber exothermic part from the two ends of outer insulator respectively by connecting plug-in unit.Be locked at last among the external insulation housing of making by inorganic insulating material or 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 is the longitudinal profile structural representation of carbon fiber electrically thermal element.
5, embodiment
Explain below with reference to Figure of description carbon fiber electrically thermal element of the present utility model being done.
Carbon fiber electrically thermal element of the present utility model, its structure is by power lead 1, external insulation housing 3, connect plug-in unit 2, outer metal joint adapter sleeve 4, interior metal joint adapter sleeve 5, carbon fiber electrothermal part 6, inner insulating layer 7 and skeleton 8 constitute, carbon fiber electrothermal part 6 layerings are coated on spiral skeleton 8 outsides, inner insulating layer 7 is stratified and set between 6 layers of skeleton 8 and the carbon fiber electrothermal parts and skeleton 8, carbon fiber electrothermal part 6 is enclosed among the external insulation housing 3 that the surface is provided with bleeding point 10 in the lump, power lead 1 inserts from the two ends of external insulation housing 3 and is connected plug-in unit 2 and joins, connect plug-in unit 2 and be provided with blind hole, the end of carbon fiber electrothermal part 6 by outer metal joint adapter sleeve 4 and interior metal joint adapter sleeve 5 clampings among blind hole.Be filled with inert gas 9 in the external insulation housing 3.
Its processing and fabricating of carbon fiber electrically thermal element 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; Metal joint adapter sleeve available metal copper pipe or sheet material are processed into, and effect is to be used for carbon fiber to be connected with power lead.Interior insulator and external insulation housing are to be made by exotic materials such as inorganic insulating material and glass insulating materials.
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 40 ℃-900 ℃; Surface heat power is at 0.2W/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 off-gauge mode, the mode that can adopt standard cell to abandon and adorn again;
5, electric property is stable, reliable, and useful life is up to more than 20 years;
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, and operating temperature range is at 40 ℃-900 ℃; Surface heat power is 0.2W/cm
2-40W/cm
2Electric heating element combines characteristics such as firm with the metallic power terminal.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.
