Abstract
The utility model provides a novel carbon fiber electrothermal element, which is composed of an outer shell, a filling insulating layer, an inner braiding insulating layer, an outer braiding insulating layer, a carbon fiber heating body, a metal screwed connecting plug and end insulating blocks. A carbon fiber electrothermal body is arranged between the inner braiding insulating layer and the outer braiding insulating layer. The filling insulating layer is arranged between the outer braiding insulating layer and the outer shell. The end insulating blocks clog both ends of the outer shell. The metal screwed connecting plug is connected with the end of the carbon fiber heating body. A power supply conducting wire which is connected with the metal screwed connecting plug together passes through the clogging of the end insulating blocks and extends outwards. The novel carbon fiber electrothermal 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 usage temperature range, broad application range, etc.
Description
1, technical field
The utility model relates to a kind of electrical heater element, specifically a kind of novel carbon fiber electric heating element.
2, technical background
As everyone knows, the electric heater of prior art mostly uses nichrome, Aludirome and Cu alloy material to do electric heating element.Reason owing to these electric heating element materials self inherent characteristic, in use have a lot of deficiencies, as: the electric heating element that general nichrome material, Aludirome and Cu alloy material are made, though plasticity and flexible are arranged, but electric heating element is easily oxidation of surface in the electric heating use, cause local current excessive thus, temperature is too high and be blown.Have visible light to exist simultaneously in the electric heating process, so the heat efficiency is low.Though above-mentioned thermo electric material has certain plasticity and flexible, but they are difficult to be made into the electric heating element of geometry arbitrarily, do not have anti-permanent and random bending property and influence its range of application.
3, summary of the invention
The purpose of this utility model 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 novel carbon fiber electric heating element.
The purpose of this utility model realizes in the following manner, adopts weaving carbon fiber bundle, carbon fiber knit band to replace common nickel alloy material to make heater, utilizes inorganic material filler and inorganic material braid to make insulation system novel carbon fiber electric heating element.
4, description of drawings
Accompanying drawing is the structural representation of novel carbon fiber electric heating element.
5, embodiment
Explain below with reference to accompanying drawing novel carbon fiber electric heating element of the present utility model being done.
Novel carbon fiber electric heating element of the present utility model, as shown in drawings, its structure is by shell 1, fill insulating barrier 2, interior braiding insulating barrier 4, outer braiding insulating barrier 3, carbon fiber exothermic part 5, metal spiral connects plug-in unit 7 and overhang insulation piece 6 constitutes, carbon fiber electrothermal part 5 is arranged on interior braiding insulating barrier 4 and weaves outward between the insulating barrier 3, filling insulating barrier 2 is arranged between outer braiding insulating barrier 3 and the shell 1,6 shutoff of overhang insulation piece are at the two ends of shell 1, the end that metal spiral connects plug-in unit 7 and carbon fiber exothermic part 5 joins, and be connected power lead that plug-in unit 7 links together to pass 6 shutoff of overhang insulation piece protruding with metal spiral.
Its processing and fabricating of novel 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; Metal spiral connects plug-in unit available metal copper pipe or sheet material is processed into, and effect is to be used for carbon fiber to be connected with power connection.
The advantage of the novel carbon fiber 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/cm
2-40W/cm
2Between, the technical parameter range of variation is wide;
4, under direct current 1.5V voltage, just can drive heating;
5, the geometry range of variation 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 novel carbon fiber 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.
