The structure comprises an external connection electrode, a connection molybdenum sheet, a carbon fiber heating body, an internal electrode, a carbon fiber heating body supporting skeleton and a crust protective layer. The carbon fiber heating body supporting skeleton is arranged in the inner cavity of the crust protective layer. The carbon fiber heating body is coated out the outer layer of the carbon fiber heating body supporting skeleton. Compared with the prior art, the filament carbon fiber heating pipe of the utility model has the characteristics of simple structure, long service life, high conversion efficiency of the electricity and the heat, broad operating temperature range, etc. and does not have the visible light in the operating process.
Description
1, technical field
The utility model relates to a kind of electrical heating elements, a kind of specifically long filament carbon fiber heating tube.
2, background technology
As everyone knows, the thermo electric material under the prior art mostly uses nichrome, molybdenum filament, copper wire, tungsten filament or ptc material to do electric heating element.Reason owing to these thermo electric materials self inherent characteristic, in use exist many deficiencies, as the electric heating element that general nichrome material, molybdenum filament, copper wire, tungsten filament material are made, 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; Easily decay and puncture of electrical heating power during ptc material uses, useful life is short, and the heat efficiency is low.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, provides that a kind of simple in structure, long service life, electric conversion efficiency height, operating temperature range are wide, the long filament carbon fiber heating tube of no visible light in the course of work.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of long filament carbon fiber heating tube; by external electrode; connect molybdenum sheet; carbon fiber exothermic part; interior electrode; carbon fiber exothermic part support frame and shell protective layer constitute; be provided with the carbon fiber exothermic part support frame in the inner chamber of shell protective layer; the inside, two ends of carbon fiber exothermic part support frame is fixed with interior electrode by interior electrode holder; carbon fiber exothermic part support frame skin is coated with carbon fiber exothermic part; the electrode outside in the carbon fiber exothermic part at carbon fiber exothermic part support frame two ends is fixed in by clamping element; interior electrode links to each other with external electrode by the connection molybdenum sheet of establishing in the shell protective layer two ends, is filled with protective gas in the shell protective layer.
The shell protective layer is provided with exhaust nozzle.
Long filament carbon fiber heating tube of the present utility model is compared with prior art, has that simple in structure, long service life, electric conversion efficiency height, operating temperature range are wide, characteristics such as no visible light in the course of work, and except that above characteristics, the utility model also comprises:
1, structural design is simple;
2, thermo-lag is little, quick heating, and heating temp is even;
3, electric property is stable, and reliable, useful life is up to more than 5 years;
4, applied environment: can be applied in the air of industry, agricultural, civil area and liquid heat or the like widely.
Thereby, the utlity model has excellent popularization use value.
4, description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the structural representation of long filament carbon fiber heating tube.
5, embodiment
Explain below with reference to Figure of description long filament carbon fiber heating tube of the present utility model being done.
