Description
1, technical field
The present invention relates to a kind of electrical heater element, specifically a kind of flexible braided carbon fiber heating wire.
2, technical background
It is well known that the electric heater of the prior art mostly does electric heating element using nichrome, Aludirome material.Due to
The reason of these itself inherent characteristics of electric heating element material, there are many deficiencies, such as general nichrome material, iron in use
Electric heating element made of Cr-Al alloy material, though there are plasticity and flexible, electric heating element surface in electric heating use process
It is oxidizable, it thereby results in hot-spot and is blown.Simultaneously with the presence of visible light during electric heating, therefore the thermal efficiency is low.It is above-mentioned
Though thermo electric material has certain plasticity and flexible, they are but difficult to be fabricated to arbitrary geometry, and do not have
Resistance to permanent and random bending property and influence its application range.
3, summary of the invention
Carbon fiber is usually to be used to make organic or inorganic composite material, as made the components on aerospace vehicle, with
Its heat-resisting, light-weight and high mechanical strength and it is famous, but do not have also and can arbitrarily be bent and resistance to permanent flexible braided carbon fiber electricity
Tropical product comes out and has a reported in literature.
The purpose of the use of the new type is to provide that a kind of structure is simple, long service life, plasticity are good, electric conversion efficiency
It is high, operating temperature range is wide, a kind of Carbon Fiber Electric Heating Element of the course of work without visible light.
The purpose of the present invention is what is realized in the following manner, replaced using weaving carbon fiber beam or carbon fiber braid over braid common
Nickel alloy material make heater, a kind of Carbon Fiber Electric Heating Element is made.
4, Detailed description of the invention
Attached drawing is a kind of structural schematic diagram of Carbon Fiber Electric Heating Element.
A kind of Carbon Fiber Electric Heating Element of the invention is described in detail below referring to attached drawing.
A kind of Carbon Fiber Electric Heating Element of the invention, structure be by weaving carbon fiber beam 1, flexible electric heating line insulating layer 2,
Metal spiral connector sleeve 3 and power lead 4 are constituted, and weaving carbon fiber beam 1 is arranged among flexible electric heating line insulating layer 2, braiding
The end of carbon fiber bundle 1 is connected by metal spiral connector sleeve 3 with power lead 4, and the outside of metal spiral connector sleeve 3 passes through exhausted
5 cladding of edge set.
5, embodiment
Its processing and fabricating of a kind of Carbon Fiber Electric Heating Element of the invention is very simple and convenient, processing shown in by specification attached drawing
Production.
The processing and fabricating of carbon fiber is known technology, and polypropylene hydrogen-based carbon fiber or asphalt base carbon fiber can be used in electric heating element
The braid over braid or cotton rope of various structures are woven by general fibrage equipment, it is therefore an objective to improve the mechanical strength of carbon fiber.
Thermoplastic, rubber plastic blend body and enhancing rubber plastic blend can be used in weaving carbon fiber beam or braiding beam insulating materials
Body insulation.Traditional insulating process production weaving carbon fiber beam or carbon fiber braid over braid and braiding gold can be used in insulating treatment method
Belonging to the insulation between spiral connector sleeve and power lead can be used thermosetting property, thermoplastic, rubber plastic blend body and enhancing rubber and plastic
Mixture insulation.Traditionally insulating process production can be used in insulating treatment method.
The invention has the characteristics that
1, structure design is simple；
2, thermo-lag is small, quick heating, and heating temperature is uniform；
3, surface temperature is at 40 DEG C -500 DEG C；Surface heat power technical parameter between 0.2W/cm2-12W/cm2 becomes
Different range is wide；
4, fever can be driven under direct current 1.5V voltage；
5, geometry range of variation is wide, therefore in actual application, that is, off-gauge mode can be used, and can adopt
With the mode of standard block assembly；
6, electric property is stable, reliable, and service life is up to 10 years or more；
7, it application environment: can use in water, in air and in soil.Application range: can be used for pipe insulation, and floor adds
Heat, thermal therapy health-care product, warm-air drier, air-conditioning supplementary heating, cold water heating etc..
Thus, flexible braided carbon fiber ribbon heater of the invention compared to the prior art, have the thermal efficiency it is high (up to 98% with
On), random usability is strong, plasticity is good, can be fabricated to random geometry, structure and simple production process, use scope is wide,
(operating temperature is in 40 DEG C of -300 DEG C of ranges) surface heat power is in 0.2W/cm2) -12W/cm2；Electric heating element connects with plain conductor
Head is firmly combined；The advantages that can driving fever under direct current 1.5V low-voltage.Also with designing, reasonable, structure is simple, is easy to
Processing, the features such as easy to use, the thermal efficiency is high, long service life, use temperature range are wide and has a wide range of application.Thus, have
Good popularizing value.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
