Abstract
The utility model provides an electric heating element made with flexible braided carbon fiber. The utility model is composed of a braided carbon fiber bundle, a flexible electric heating wire insulating layer, a metallic spiral connecting sleeve and a power supply conducting wire. The utility model is characterized in that the braided carbon fiber bundle is arranged in the flexible electric heating wire insulating layer, the end head of the braided carbon fiber bundle is connected with the power supply conducting wire via the metallic spiral connecting sleeve, and the outer side of the metallic spiral connecting sleeve is coated by an insulating sleeve. The electric heating element made with flexible braided carbon fiber of the utility model has the characteristics of rational process design, simple structure, easy manufacturing, convenient operation, high thermal efficiency, long service life, wide ranges of usable temperature, broad application, etc.
Description
1, technical field
The utility model relates to a kind of electrical heater element, specifically a kind of flexible weaving carbon fiber heating wire.
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 weaving carbon fiber ribbon heater product 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 flexible weaving carbon fiber electric heating element.
The purpose of this utility model realizes in the following manner, adopts weaving carbon fiber bundle or carbon fiber knit band to replace common nickel alloy material to make heater, makes flexible weaving carbon fiber electric heating element.
Accompanying drawing is the structural representation of flexible weaving carbon fiber electric heating element.
4, description of drawings
Explain below with reference to accompanying drawing electric heating element made with flexible braided carbon fiber of the present utility model being done.
Electric heating element made with flexible braided carbon fiber of the present utility model, its structure are by weaving carbon fiber bundle 1, flexibility Heating wire insulating barrier 2, metal spiral adapter sleeve 3 and power lead 4 consist of, and weaving carbon fiber bundle 1 is arranged on gentle The property heating wire insulating barrier 2 among, lead by metal spiral adapter sleeve 3 and power supply the termination of weaving carbon fiber bundle 1 Line 4 joins, and the outside of metal spiral adapter sleeve 3 coats by insulation sleeve 5.
5, execution mode
Flexible its processing and fabricating of weaving 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 be woven into the braid over braid or the cotton rope of various structures by general fibrage equipment, and purpose is to improve the mechanical strength of carbon fiber.
Weaving carbon fiber bundle or braiding bundle insulating material can adopt thermoplastics, rubber plastic blend body and strengthen the insulation of rubber plastic blend body.The insulation that insulating treatment method can adopt traditional insulating process to make between weaving carbon fiber bundle or carbon fiber knit band and braided metal spiral adapter sleeve and the power lead can be adopted thermosetting, thermoplastics, rubber plastic blend body and the insulation of enhancing rubber plastic blend body.Insulating treatment method can adopt traditional insulating process to make.
Characteristics of the present utility model are:
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/cm2-12W/cm
2Between skill Art parameter variation wide ranges;
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 be used for pipe insulation, floor heating, thermotherapy health products, warm-air drier, air-conditioning supplementary heating, cold water heating or the like.
Thereby, flexible weaving carbon fiber of the present utility model ribbon heater is compared with prior art, have heat efficiency height (reaching more than 98%), usability is strong at random, plasticity good, can be made into that random geometry, structure and production technology are simple, the scope of application is wide, (working temperature is 40 ℃ of-300 ℃ of scopes) surface heat power is at 0.2W/cm
2)-12W/cm
2Electric heating element combines firmly with the plain conductor joint; Can under direct current 1.5V low-voltage, can drive advantages such as heating.Also have reasonable in design, simple in structure, be easy to processing, easy to use, characteristics such as the heat efficiency is high, long service life, serviceability temperature wide ranges and applied range.Thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
