Abstract
The utility model provides a carbon fiber electro-thermal cable, the structure of which consists of a cable sheath, cable external insulating sleeve, a carbon fiber electricity conducting and heat generating layer, a power source conductor with an insulating layer and insulating fillings. The power source conductor with an insulating layer is fixed in the carbon fiber electricity conducting and heat generating layer through the insulating fillings; the cable insulating sleeve is arranged between the cable sheath and the carbon fiber electricity conducting and heat generating layer. Compared with the prior art, the carbon fiber electro-thermal cable of the utility model has the advantages of rational design, simple structure, easy processing, convenient application, high thermal efficiency, long service life, wide applicable temperature range, wide application range, etc., and is satisfactory heating equipment for heating oil transporting pipelines used in oilfields and oil pumping pipelines used in oil wells.
Description
1, technical field
The utility model relates to a kind of electric heating device, specifically a kind of carbon fiber electric heating cable.
2, technical background
As everyone knows, the electric heater of prior art mostly uses nichrome, Aludirome and Cu alloy material to do electric heating element.Reason owing to these electric heating element materials self inherent characteristic, in use have a lot of deficiencies, as: the electric heating element that general nichrome material, Aludirome and Cu alloy material are made, though plasticity and flexible are arranged, but electric heating element is easily oxidation of surface in the electric heating use, cause local current excessive thus, temperature is too high and be blown.Have visible light to exist simultaneously in the electric heating process, so the heat efficiency is low.Though above-mentioned thermo electric material has certain plasticity and flexible, but they are difficult to be made into the electric heating element of geometry arbitrarily, do not have anti-permanent and random bending property and influence its range of application.In addition, also be not useful at present the heater of flexible good, the long service life of having of oil field oil pipeline and oil well oil-pumping pipeline heating, also not having can arbitrarily crooked and anti-permanent carbon fiber electric heating cable product appearance and reported in literature is arranged.
3, summary of the invention
The novel purpose of this use provides that a kind of simple in structure, long service life, plasticity are good, the course of work does not have visible light, electric conversion efficiency height, operating temperature range are wide, can be used for the heating of oil field oil pipeline and oil well oil-pumping pipeline, and it is good to have flexibility, the carbon fiber electric heating cable of long service life.
The purpose of this utility model realizes in the following manner, adopts carbon fibre material to replace common materials such as nickel alloy to do that heater and other electric conducting material and insulating material are compound makes carbon fiber electric heating cable of the present utility model.
Accompanying drawing is the structural representation of carbon fiber electric heating cable.
4, description of drawings
Explain below with reference to Figure of description carbon fiber electric heating cable of the present utility model being done.
As shown in drawings: carbon fiber electric heating cable of the present utility model, its structure is to be made of the power lead 5 of cable sheath 1, cable external insulation sleeve 2, electric conduction of carbon fiber heating layer 3, tape insulation layer 4 and insulating packing 6, the power lead 5 of tape insulation layer 4 is fixed on by insulating packing 6 among the electric conduction of carbon fiber heating layer 3, and cable insulation cover 2 is arranged between cable sheath 1 and the electric conduction of carbon fiber heating layer 3.
5, execution mode
Its processing and fabricating of carbon fiber electric heating cable 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 crust available metal net of carbon fiber electric heating cable or metal bellows or other metal or non-metallic casing are made, and the electric conduction of carbon fiber heating layer can use carbon fibre web, carbon fiber bundle, carbon-fiber film to make.Make carbon fibre web, carbon fiber bundle, the employed carbon fibre material of carbon-fiber film, carbon fibre material can use polypropylene hydrogen base carbon fibre or asphalt base carbon fiber to make, and the manufacture craft of carbon fiber is a known technology.Power lead can adopt conventional power lead.Insulation sheath and insulating packing can adopt general insulating material processing and fabricating.
The carbon fiber electric heating cable that this use is novel have reasonable in design, manufacture craft is simple, the heat efficiency is high (reaching more than 98%), usability is strong at random, plasticity good, the scope of application is wide, (working temperature is 40 ℃ of-500 ℃ of scopes; Surface heat power is at 0.2W/cm
2-12W/cm
2) carbon fiber electrothermal part and power lead form the loop and can use the heating of direct current 1.5V driven.
1, structural design is simple.
2, thermo-lag is little, quick heating, and heating temp is even.
3, surface temperature is at 40 ℃-500 ℃; Surface heat power is at 0.2W/cm
2-12W/cm
2Between, the technical parameter range of variation is wide.
4, can use the heating of 1.5V driven.
5, the geometry range of variation is wide, therefore in actual application, can adopt off-gauge mode that can adopt standard cell to abandon and adorn again to use.
6, electric property is stable, reliable, and useful life is up to more than 10 years;
7, applied environment: can in water, oil, air and soil, use.
Range of application: can be used for pipe insulation, floor heating, thermotherapy health products, warm-air drier, air-conditioning supplementary heating, water heating and the heating of fluid body or the like.
Carbon fiber electric heating cable of the present utility model is compared with existing technology, have reasonable in design, structure is simple Single, be easy to processing, easy to use, the thermal efficiency is high, long service life, serviceability temperature wide ranges and use model Enclosing the characteristics such as wide, is the good heating equipment of oil field oil pipeline and oil well oil-pumping pipeline heating. Thereby, tool Good popularizing value is arranged.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
