Description
1, technical field
The utility model relates to a kind of carbon fiber electrically heater, a kind of specifically carbon felt outsourcing heat resistance fiber heating core energy-saving carbon fiber electrothermal tube.
2, background technology
As everyone knows, the heating tube under the prior art mostly uses nichrome, molybdenum filament or tungsten filament to do electric heating element.Reason owing to these thermo electric materials self inherent characteristic, in use exist many deficiencies, the electric heating element of making as general nichrome material, molybdenum filament, tungsten filament material, 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.The carbon fiber as electrical hot body is admitted and is accepted by people, but the carbon fiber electrically hot material of prior art, the deficiency that in use exists as the electric heating element of doing with the carbon felt is: yielding during use, photochromic inhomogeneous, can not high-powerly use down, useful life is short.The electric heating element that also useful long filament carbon fiber is made, the deficiency of existence is that power is wayward.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
Technical assignment of the present utility model is at above weak point, the carbon felt outsourcing heat resistance fiber heating core energy-saving carbon fiber electrothermal tube that provide that a kind of process structure is simple, long service life, electric conversion efficiency height, operating temperature range are wide, do not have visible light in the course of work, far infrared radiation efficient is high.
Carbon felt outsourcing heat resistance fiber heating core energy-saving carbon fiber electrothermal tube of the present utility model, form by quartzy shell, external electrode, transition brace and heating core, netted heat resistance fiber sheath outside heating core wraps in by the carbon fiber felt rug with by braiding is formed and is arranged in the quartzy shell, the interior electrode that is connected with the transition brace is inserted in the two ends of carbon fiber felt rug, also is provided with spiral fastener at the two ends of heating core.
Carbon felt outsourcing heat resistance fiber heating core energy-saving carbon fiber electrothermal tube of the present utility model is compared with prior art, the effect that is had be to use the life-span long, electric conversion efficiency is high, operating temperature range is wide, heating process is indeformable, can high-powerly use down, photochromic evenly, far infrared radiation efficient height, characteristics such as no visible light in the course of work, except that above characteristics, the utility model also has the following advantages:
(1) structural design is simple;
(2) thermo-lag is little, quick heating, and heating temp is even;
(3) electrical work stable performance, reliable.Energising work was not polluted in the pipe in 6000 hours continuously, and heating core does not damage.
(4) applied environment: can be applied in the air of industry, agricultural, civil area and liquid heat or the like widely, thereby, have good value for applications.
