Description
1, technical field
The utility model relates to a kind of electrical heating elements, the compound heating element of specifically a kind of carbon fiber.
2, technical background
As everyone knows, the electric heating element of prior art mostly uses nichrome, molybdenum filament, tungsten filament 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, molybdenum filament, tungsten filament material, easily oxidation of surface in the electric heating use causes local overheating thus and is blown, and useful life is short.Have visible light to exist simultaneously in the electric heating process, so the heat efficiency is low.Though above-mentioned thermo electric material has the field of the application of broad, but they are difficult to be made into the electric heating element that uses anti-permanent and heat efficiency height and do not influence its range of application.
3, summary of the invention
The purpose of this utility model is at above weak point, and a kind of simple in structure, long service life, electric conversion efficiency height, operating temperature range is wide, the course of work does not have visible light the compound heating element of carbon fiber are provided.
The technical scheme that its technical problem that solves the utility model adopts is: adopt carbon fiber bundle; carbon fiber preform replaces common nichrome; molybdenum filament; the tungsten filament material is made heater; the two ends that are arranged on the carbon fiber electrothermal part in the insulation shell are linked together by screw-tightened ring and interior power lead; the middle part of carbon fiber electrothermal part is on the changed course skeleton that is arranged at insulation shell inner chamber end; the external power lead; interior power lead and transition brace join in the end seat that is enclosed in insulation shell; insulation shell is coated with the heat conduction protective sleeve; the end seat joint of heat conduction protective sleeve and insulation shell is socketed with the insulation fixed cover, and the joint, termination of heat conduction protective sleeve and insulation shell is socketed with the heat conduction end cap.The termination of insulation shell has bleeding point, inner insulating layer can be set in the inner chamber of insulation shell also inner insulating layer can be set.
The compound heating element of carbon fiber of the present utility model is compared with prior art, has reasonable in design, and processing technology is simple, easy to use, the life-span is long, heat efficiency height, characteristics such as serviceability temperature wide ranges and applied range, thereby, have good value for applications.
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 the compound heating element of carbon fiber;
Accompanying drawing 2 is the enlarged drawing at Figure 1A place.
5, embodiment
Explain below with reference to Figure of description the compound heating element of carbon fiber of the present utility model being done.
The compound heating element of carbon fiber of the present utility model; its structure is by external power lead 1; transition brace 2; interior power lead 3; insulation fixed cover 5; carbon fiber electrothermal part 6; heat conduction protective sleeve 9; insulation shell 8; changed course skeleton 10 and heat conduction end cap 11 constitute; the two ends that are arranged on the carbon fiber electrothermal part 6 in the insulation shell 8 link together by screw-tightened ring 4 and interior power lead 3; the middle part of carbon fiber electrothermal part 6 is on the changed course skeleton 10 that is arranged at insulation shell 8 inner chamber ends; external power lead 1; interior power lead 3 joins with transition brace 2 in the end seat that is enclosed in insulation shell 8; insulation shell 8 is coated with heat conduction protective sleeve 9; heat conduction protective sleeve 9 is socketed with insulation fixed cover 5 with the end seat joint of insulation shell 8, and heat conduction protective sleeve 9 is socketed with heat conduction end cap 11 with the joint, termination of insulation shell 8.The termination of insulation shell 8 has bleeding point 12, inner insulating layer 7 can be set in the inner chamber of insulation shell 8 also inner insulating layer 7 can be set.
Its processing and fabricating of the compound heating element of carbon fiber 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 or asphalt base carbon fiber to make; Inner insulating layer is to be made by inorganic insulating material, quartzy class glass insulating material and inert gas, and the external insulation housing is to be made by exotic materials such as inorganic insulating material and quartzy class glass insulating materials; The insulation fixed cover is to make with organic material and inorganic material; The transition brace is made by metal material; The heat conduction protective sleeve is that sheet, tubulose or webmaster shape metal material are made.
The advantage of the carbon fibre compound heating element that this use is novel is:
1, structural design is simple;
2, thermo-lag is little, quick heating, and heating temp is even;
3, surface temperature is at 200 ℃-900 ℃; Surface heat power is at 5W/cm2-40W/cm
2It Between, the technical parameter range of variation is wide;
4, the geometry range of variation is wide, therefore in actual application, can adopt standard or non-standard unit mode to use;
5, electric property is stable, reliable, and useful life is up to more than 10000 hours.
6, applied environment: can be in water, use in the air.Industry can be applied in widely, agricultural, air heat of civil area or the like.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
