The structure comprises power source conducting wires coated with an insulation layer, a carbon fiber conducting layer, a carbon fiber outer insulation layer and a metallic knitted net layer. The outer sides of the two side-by-side power source conducting wires coated with the insulation layer are coated with the carbon fiber conducting layer, the carbon fiber outer insulation layer and the metallic knitted net layer in sequence from inner to outer. The joints for connecting with the power source conducting wire and the carbon fiber conducting layer are respectively arranged on the different ends of the two power source conducting wires. Comparing with the prior art, the double-conducting wire carbon fiber electrothermal cables of the utility model has the characteristics of simple structure, convenient manufacture and use, long service life, high conversion efficiency of the electricity and the heat, broad operating temperature range, etc. and do not have the visible light in the operating process.
Description
1, technical field
The utility model relates to a kind of electrical heating elements, specifically a kind of two-conductor line carbon fiber electric heating cable.
2, technical background
As everyone knows, the heater wire under the prior art mostly uses nichrome, molybdenum filament, tungsten filament or ptc material to do electric heating element.Reason owing to these thermo electric materials self inherent characteristic, in use exist many deficiencies, as the electric heating element that general nichrome material, molybdenum filament, tungsten filament material are made, easily oxidation of surface in the electric heating process, cause local overheating thus and be blown, useful life is short.Have visible light to exist in the process of electric heating simultaneously, so the heat efficiency is low; Easily decay and puncture of electrical heating power during ptc material uses, useful life is short, and the heat efficiency is low.Though above-mentioned thermo electric material has the application of broad, they but are difficult to be made into the anti-permanent and high electric heating element that does not influence its range of application again of the heat efficiency of use.
3, summary of the invention
The purpose of this utility model is at above weak point, provide a kind of simple in structure, processing and fabricating and easy to use, the life-span is long, electric conversion efficiency is high, operating temperature range is wide, the two-conductor line carbon fiber electric heating cable of no visible light in the course of work.
The technical scheme that its technical problem that solves the utility model adopts is: two parallel power lead outsides that are covered with insulating barrier are coated with electric conduction of carbon fiber layer, carbon fiber external insulation layer and metal knitted stratum reticulare from inside to outside successively; Two power leads are provided with the joint that connects power lead and electric conduction of carbon fiber layer at the difference end respectively; Metal knitted stratum reticulare outside also is coated with one deck sheath.
Two-conductor line carbon fiber electric heating cable of the present utility model is compared with prior art, have simple in structure, processing and fabricating and easy to use, the life-span is long, electric conversion efficiency is high, operating temperature range is wide, characteristics such as no visible light in the course of work.
In addition, it also has following characteristics:
(1) thermo-lag is little, quick heating, and heating temp is even;
(2) the technical parameter range of variation is wide;
(3) the geometry range of variation is wide, therefore in actual application, can adopt standard or non-standard unit mode to use;
(4) electric property is stable, and reliable, useful life is up to more than 5 years;
(5) applied environment: can in liquid and air, use.Can be applied in air heat of industry, agricultural, civil area or the like widely.
Thereby two-conductor line carbon fiber electric heating cable of the present utility model has good value for applications.
4, description of drawings
Accompanying drawing is the structural representation of two-conductor line carbon fiber electric heating cable;
5, embodiment
Explain below with reference to Figure of description two-conductor line carbon fiber electric heating cable of the present utility model being done.
Two-conductor line carbon fiber electric heating cable of the present utility model, its structure is to be made of the power lead 1 that is covered with insulating barrier 2, electric conduction of carbon fiber layer 3, carbon fiber external insulation layer 5 and metal knitted stratum reticulare 6, and two parallel power lead 1 outsides that are covered with insulating barrier 2 are coated with electric conduction of carbon fiber layer 3, carbon fiber external insulation layer 5 and metal knitted stratum reticulare 6 from inside to outside successively; Two power leads 1 are fastening with power lead 1 and 3 after-combustion of electric conduction of carbon fiber layer with plain conductor after the difference end is peelled off insulating barrier 2 respectively, welding again, thus make joint 4; Metal knitted stratum reticulare 6 outsides also are coated with one deck sheath 7.
During use, two power leads are inserted the two poles of the earth of power supply respectively.After the energising, electric current is passed to electric conduction of carbon fiber layer 3 through the joint 4 of a power lead, arrive another root lead by the joint through another root power lead behind the other end of electric conduction of carbon fiber layer 3 arrival two-wire carbon fiber electrothermal line again, thereby constitute a current circuit, make electric conduction of carbon fiber layer 3 conductive exothermal.
Its processing and fabricating of two-conductor line carbon fiber electric heating cable of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.The processing method of carbon fiber is a known technology, and the electric conduction of carbon fiber layer can adopt the method for braiding, single or many after-combustion, fibre bundle to make; Insulating barrier can adopt engineering plastics to coat by extrusion method; Power lead adopts conventional method processing; The joint that connects power lead and carbon fiber knit layer adopts naked plain conductor, and metal knitted stratum reticulare adopts the metal wire rod braiding to form.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
