Description

Carbon fiber electrothermal line

1, technical field

The utility model relates to a kind of electric heating device, specifically a kind of carbon fiber electrothermal line.

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 purpose of this utility model 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 have flexible good, long service life carbon fiber electrothermal line.

The purpose of this utility model realizes in the following manner, adopt carbon fibre material to replace common materials such as nickel alloy to make heater, and adopt the glass fibre and the composite material of resinae composition to do that insulating material is compound makes carbon fiber electrothermal line of the present utility model.

4, description of drawings

Accompanying drawing 1 is the structural representation of carbon fiber electrothermal line.

5, embodiment

Explain below with reference to Figure of description carbon fiber electrothermal line of the present utility model being done.

Carbon fiber electrothermal line of the present utility model, its structure are to be made of carbon fiber exothermic part 1 and insulating barrier 2, and carbon fiber exothermic part 1 is fixed among the insulating barrier 2 of layering setting.Carbon fiber exothermic part 1 is pencil or braid shape.

Its processing and fabricating of carbon fiber electrothermal line 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 novel carbon fiber electrothermal line of this use has 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, and (working temperature is 40 ℃ of-500 ℃ of scopes; Surface heat power is at 0.2W/cm ²-12W/cm ²) carbon fiber exothermic 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, surperficial serviceability temperature is at 40 ℃-500 ℃; Surface heat power is at 0.2-12W/cm ²Between, the technical parameter range of variation is wide.

4, can use the heating of 1.5V direct voltage drive.

5, the geometry range of variation is wide, therefore in actual application, can adopt MULTILAYER COMPOSITE coated insulation layer to form according to the requirement of heating wire various outer diameter size.

6, electric property is stable, reliable, and useful life is up to more than 20 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, thermal cloth, warm-air drier, air-conditioning supplementary heating, water heating and the heating of fluid body or the like.

Carbon fiber electrothermal line of the present utility model is compared with existing technology, have reasonable in design, structure is simple Singly, be easy to processing, easy to use, the spies such as the thermal efficiency is high, long service life, serviceability temperature wide ranges Point, and this can be widely used in industrial circle after using novel Yu metal material secondary mechanical compound, is The at present existing the best substitute products of heating. Thereby, have good value for applications.

Except the described technical characterictic of specification, be the known technology of those skilled in the art.

Claims (1)

1, carbon fiber electrothermal line comprises carbon fiber exothermic part and insulating barrier, it is characterized in that the insulating barrier layering is coated on outside the carbon fiber exothermic part.
