Abstract
The utility model provides a ceramic carbon fiber electric heating element, which is composed of a shell body of the electric heating element, an insulation body, a carbon fiber electric heating element and insulating terminals. The utility model is characterized in that the carbon fiber electric heating element, the insulation body and the insulating terminals are fixed in the shell body of the electric heating element, and the insulating terminals are arranged at two ends of the shell body of the electric heating element. The ceramic carbon fiber electric heating element of the utility model has the characteristics of rational process design, simple structure, easy manufacturing, convenient operation, high thermal efficiency, long service life, wide ranges of usable temperature, broad application, etc.
Description
1, technical field
The utility model relates to a kind of electric heating device, specifically a kind of ceramic carbon fibre electric heating element.
2, technical background
As everyone knows, the electric heater of prior art mostly uses nichrome, Aludirome 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, Aludirome material, electric heating element is easily oxidation of surface in the electric heating use, is taken aim at into local overheating and is blown by A, 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, use anti-permanent and heat efficiency height and influence its range of application but they are difficult to be made into.
3, summary of the invention
Carbon fiber normally is used to make organic or inorganic composite materials, and is heat-resisting, in light weight and mechanical strength is high and celebrated with it as making the parts on the aerospace vehicle, but also not useful ceramic-insulated carbon fiber electric heating component products is come out and reported in literature is arranged.
The novel purpose of this use provides 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 carbon fiber electric heating device.
The purpose of this utility model realizes in the following manner, adopts carbon fiber to replace common nickel alloy material to make heater, utilizes pottery to make the novel ceramic carbon fibre electric heating element of insulation system.
Accompanying drawing is the structural representation of ceramic carbon fibre electric heating element.
4, description of drawings
Explain below with reference to Figure of description ceramic carbon fibre electric heating element of the present utility model being done. Ceramic carbon fibre electric heating element of the present utility model, its structure are by heating housing 5, insulator 3, carbon Fiber electric heating element and insulating end 4,6 consist of, Carbon Fiber Electric Heating Element, insulator 3 and insulating end 4, 6 fixedly among the heating housing, and insulating end 4,6 is arranged on the two ends of Carbon Fiber Electric Heating Element housing 5.
Carbon Fiber Electric Heating Element is by insulating barrier 1, carbon fiber electrothermal line 2, metal joint adapter sleeve 7 and power supply Joint 8 forms, and insulating barrier 1 is coated on the outside of carbon fiber electrothermal line 2, and the termination of carbon fiber electrothermal line 2 is passed through Metal joint adapter sleeve 7 links together with power connection 8, and the lower end of power connection 8 is fixed on insulating end 6 Among, the upper end of power connection 4 is protruding from the section of insulating end 6.
5, execution mode
Flexible its processing and fabricating of wire carbon fiber electric heating element 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 carbon fibre or asphalt base carbon fiber to make; But metal joint adapter sleeve metal copper pipe or sheet material are processed into, and effect is to be used for carbon fiber to be connected with power connection.Insulator and insulating end are that insulating material exotic materials such as pottery, glass are made.
The advantage of the ceramic carbon fibre electric heating element that this use is novel is:
1, structural design is simple;
2, thermo-lag is little, quick heating. Heating temp is even;
3, surface temperature is at 40 ℃-900 ℃; Surface heat power is at 0.2W/cm2-40W/cm
2It Between, the technical parameter range of variation is wide;
4, under direct current 1.5V voltage, just can drive heating;
5, what shape range of variation of youngster is wide, therefore in actual application, can adopt off-gauge mode, the mode that can adopt standard cell to abandon and adorn again;
6, electric property is stable, reliable, and useful life is up to more than 20 years;
7, applied environment: can be in water, use in the air.Can be applied in industry widely, agricultural, the air of civil area adds, hot liquid heating or the like.
Thereby ceramic carbon fibre electric heating element of the present utility model is compared with prior art, have the heat efficiency up to more than 98%, at random usability strong, can be made into advantages such as random geometry, structure and production technology are simple.The scope of application is wide, and operating temperature range is at 40 ℃-900 ℃; Surface heat power is 0.2W/cm
2-40W/cm
2Electric heating element combines firmly with the plain conductor joint; Can under direct current 1.5V low-voltage, can drive characteristics such as heating.Also have reasonable in design, simple in structure, be easy to processing, easy to use, characteristics such as the heat efficiency is high, long service life, serviceability temperature wide ranges and applied range.Thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
