Description

The Multifunction heating wire

1, technical field

The utility model relates to a kind of electrical heating elements, specifically a kind of Multifunction heating wire.

2, technical background

As everyone knows, the heating wire of prior art mostly uses nichrome, molybdenum filament, tungsten filament or ptc 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.Easily decay and puncture of electric thermal power during ptc material uses, useful life is short, and 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 Multifunction heating wire are provided.

The technical scheme that its technical problem that solves the utility model adopts is: fixedly core squeezes, coats the carbon fibre composite conductive layer outward, the two ends of carbon fibre composite conductive layer are connected with power lead, and the carbon fibre composite conductive layer is coated with the 1-6 layer insulating.The utility model is compared with prior art, has reasonable in design, and manufacture craft is simple, and is easy to use, and the life-span is long, heat efficiency height, and characteristics such as wide and applied range of operating temperature 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 is the structural representation of Multifunction heating wire.

5, embodiment

Explain below with reference to Figure of description Multifunction heating wire of the present utility model being done.

Multifunction heating wire of the present utility model, its structure is by fixedly core 1, carbon fibre composite conductive layer 2, insulating barrier 3 and power lead 4 constitute, fixedly core 1 outer squeezing and coating have carbon fibre composite conductive layer 2, the two ends of carbon fibre composite conductive layer 2 are connected with power lead 4, and carbon fibre composite conductive layer 2 is coated with 1-6 layer insulating 3.

The advantage of the Multifunction heating wire 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 30 ℃-200 ℃; Surface heat power is between 15W/ rice-20W/ rice, and 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.

Its processing and fabricating of Multifunction heating wire of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Fixedly core useable glass fiber, chemical fibre, cotton fiber bundle or braid are made, and insulating barrier can be made with the insulating material of composite material plastics, rubber or plastics and rubber.

Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
