Abstract
The utility model provides a soft line-shaped carbon fiber electrothermal unit; the structure is that: the utility model consists of a connecting cover with a metal connecting head, a soft fiber outer coat, a fixed cover for the soft fiber outer coat, a carbon fiber electrothermal wire, an electrical supply lead, a soft composite insulated material and a filling material for the soft composite insulated material. The carbon fiber electrothermal wire is enveloped inside the soft fiber outer coat through the soft composite insulated material; the soft fiber outer coat is fixed on the end part of the connecting cover with a metal connecting head through the fixed cover for the soft fiber outer coat. The electrical supply lead is fixed on the connecting cover with the metal connecting head through the filling material for the soft composite insulated material. The carbon fiber electrothermal wire is fixed on the electrical supply lead in a screw thread way together. Compared with the prior art, the soft line-shaped carbon fiber electrothermal unit in the utility model is characterized in rational technics design, simple structure, easy to be produced, convenient use, high heat efficiency, long life time, wide temperature range and wide application range and so on. So the utility model has the much better market use value.
Description
1, technical field
The utility model relates to a kind of electric heating device, specifically a kind of flexible wire carbon fiber electric heating 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, though plasticity and flexible are arranged, but electric heating element is easily oxidation of surface in the electric heating use, causes local overheating thus and is 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 geometry arbitrarily, do not have anti-permanent and random bending property and influence its range of application.
3, summary of the invention
Carbon fiber normally is used to make organic or inorganic composite materials, as make parts on the aerospace vehicle, heat-resisting, in light weight and mechanical strength is high and celebrated with it, can arbitrarily crooked and anti-permanent flexible wire carbon fiber electric heating component products appearance and reported in literature is arranged but also do not have.
The novel purpose of this use provides a kind of simple in structure, long service life, plasticity is good, electric conversion efficiency is high, operating temperature range is wide, the course of work does not have visible light carbon fiber electric heating device.
The purpose of this utility model realizes in the following manner, adopts carbon fiber to replace common nickel alloy material to make flexible wire carbon fiber electric heating element of the present utility model as heater.
Accompanying drawing is the structural representation of flexible wire carbon fiber electric heating element.
4, description of drawings
Below with reference to Figure of description flexible linear carbon fibre electrothermal element of the present utility model being done at length Explanation.
Flexible linear carbon fibre electrothermal element of the present utility model, its structure be by metal joint adapter sleeve 2, Flexible fiber overcoat 5, flexible fiber overcoat fixed cover 6, carbon fibre electrothermal wire 4, power lead 1, flexibility Composite insulating material 3 and power lead insulating packing 7 consist of, and carbon fibre electrothermal wire 4 is exhausted by flexible compound Edge material 3 is coated among the flexible fiber overcoat 5, and flexible fiber overcoat 5 is fixed by the flexible fiber overcoat Cover 6 is fixed on the end of metal joint adapter sleeve 2, and power lead 1 is fixing by power lead insulating packing 7 Among the metal joint adapter sleeve 2, power lead 1 is fixed together with carbon fibre electrothermal wire 4 spirals.
5, execution mode
Flexible its processing and fabricating of wire carbon fiber electric heating 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.
Between carbon fiber and the flexible fiber overcoat and the insulation between metal joint adapter sleeve and the power lead can adopt traditional insulating process to make.
The use of the flexible wire carbon fiber electric heating element that this use is novel has heat efficiency height (reaching more than 98%), usability is strong at random, plasticity good, can be made into advantages such as random geometry, structure and production technology are simple.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
2Electric heating element and plain conductor joint are firm; Under direct current 1.5V low-voltage, can drive heating.
1, structural design is simple;
2, thermo-lag is little, quick heating.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 wide;
4, under direct current 1.5V voltage, just can drive heating;
5, 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;
6, electric property is stable, reliable, and useful life is up to more than 10 years;
7, applied environment: can be in water, use in the air sweetening of the soil.Range of application: can give pipe insulation, floor heating, thermotherapy health products, warm-air drier, air-conditioning supplementary heating, cold water heating or the like.
Flexible linear carbon fibre electrothermal element of the present utility model is compared with existing technology, have reasonable in design, Simple in structure, be easy to processing, easy to use, the thermal efficiency is high, long service life, serviceability temperature wide ranges and The characteristics such as applied range. Thereby, have good value for applications.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
