Description
1, technical field
The utility model relates to a kind of carbon fiber electrically heater, a kind of specifically shuffling tubulose 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 shuffling tubulose 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.
Shuffling tubulose heating core energy-saving carbon fiber electrothermal tube of the present utility model, be to make by electrode and heating core in quartzy shell, external electrode, the transition brace, heating core is arranged in the quartzy shell, heating core is to become tubulose to make by carbon fiber with the heat resistance fiber shuffling, the two ends shrink pack of heating core is on interior electrode, the cylindrical of interior electrode serrated end is provided with spiral fastener, and interior electrode is connected with external electrode by the transition brace, and the transition brace is fixed on the two ends of quartzy shell.
Shuffling tubulose 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, do not have characteristics such as visible light, far infrared radiation efficient height in the course of work, except that above characteristics, the utility model also has the following advantages:
