Description

Single conductor carbon fiber heating cable
1, technical field
The utility model relates to a kind of electrical heating elements, a kind of specifically single conductor carbon fiber heating cable.
2, background technology
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, provides that a kind of simple in structure, long service life, electric conversion efficiency height, operating temperature range are wide, the single conductor carbon fiber 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: a kind of single conductor carbon fiber heating cable, comprise power lead, wire insulation, the electric conduction of carbon fiber layer, interior electrode nipple, the electric conduction of carbon fiber layer insulating, the metal knitted net of external wire, external wire joint and outer insulation, between power lead and the outer insulation, be coated with wire insulation from the inside to the outside respectively, the electric conduction of carbon fiber layer, the metal knitted net of electric conduction of carbon fiber layer insulating and external wire, the interior electrode nipple at power lead two ends connects electric conduction of carbon fiber layer and power lead, and the external wire joint that is provided with between the two interior electrode nipples is coated with power lead from the inside to the outside respectively, wire insulation, the metal knitted net of electric conduction of carbon fiber layer and external wire.
Single conductor carbon fiber heating cable of the present utility model is compared with prior art, have that simple in structure, long service life, electric conversion efficiency height, operating temperature range are wide, characteristics such as no visible light in the course of work, except that above characteristics, the utility model also comprises:
1, mechanism design is simple;
2, thermo-lag is little, quick heating, and heating temp is even;
3, electrical heating power is adjustable, 50 ℃-200 ℃ of surface Working Temperature, and surface heat power is between 10W/ rice-60W/ rice;
4, the geometry range of variation is wide, therefore in actual application, can adopt standard or non-standard unit mode to use;
5, electric property is stable, and reliable, useful life is up to more than 5 years;
6, applied environment: can in liquid and air, use.Can be applied in the liquid of industry, agricultural, civil area and air heat or the like widely.
Thereby, the utlity model has excellent popularization use value.
4, description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the structural representation of single conductor carbon fiber heating cable.
5, embodiment
Explain below with reference to Figure of description single conductor carbon fiber of the present utility model heating cable being done.
Single conductor carbon fiber heating cable of the present utility model, its structure is by power lead 1, wire insulation 2, electric conduction of carbon fiber layer 3, interior electrode nipple 4, electric conduction of carbon fiber layer insulating 5, the metal knitted net 6 of external wire, external wire joint 7 and outer insulation 8 constitute, between power lead 1 and the outer insulation 8, be coated with wire insulation 2 from the inside to the outside respectively, electric conduction of carbon fiber layer 3, the metal knitted net 6 of electric conduction of carbon fiber layer insulating 5 and external wire, the interior electrode nipple 4 at power lead 1 two ends connects the external wire joint 7 that is provided with between the electrode nipple 4 in electric conduction of carbon fiber layer 3 and the power lead 1, two and is coated with power lead 1 from the inside to the outside respectively, wire insulation 2, the metal knitted net 6 of electric conduction of carbon fiber layer 3 and external wire.
When the utility model is installed, use is coated with the power lead 1 of wire insulation 2, peel off power lead 1 two ends one section lead insulating barrier 2 respectively, then at its outside electric conduction of carbon fiber layer 3 that coats, the power lead 1 that the interior electrode nipple 4 that utilizes electric conducting material to make will be peelled off wire insulation 2 is connected with electric conduction of carbon fiber layer 3, then at its outside electric conduction of carbon fiber layer insulating 5 that coats, get the middle position between the electrode nipple 4 in two, peel off one section electric conduction of carbon fiber layer insulating 5, coat the metal knitted net 6 of external wire then, utilize external wire joint 7 that electric conducting material makes with the metal knitted net 6 of external wire, electric conduction of carbon fiber layer 3 connects, and coats outer insulation 8 at skin at last and gets final product.
Insert power supply at interior electrode nipple 4 or power lead 1 with external wire joint 7 two ends, electric current forms the loop through interior electrode nipple 4, electric conduction of carbon fiber layer 3, the metal knitted net 6 of external wire and external wire joint 7, can realize heating function of the present utility model.
Single conductor carbon fiber of the present utility model heating cable, electric conduction of carbon fiber layer 3 can adopt braiding, single or many after-combustion or carbon fiber bundle making; The material of electric conduction of carbon fiber layer insulating 5 can utilize expressing technique for engineering plastic materials and make; The metal knitted net 6 of external wire adopts metal wire rod to make, and its processing and fabricating is very simple and convenient, gets final product processing and fabricating shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
