Description

Multicore carbon fiber heater wire

1, technical field

The utility model relates to a kind of electrical heating elements, a kind of specifically multicore carbon fiber heater wire.

2, background technology

As everyone knows, the heater wire under the prior art mostly uses nichrome, molybdenum filament, 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, 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

The purpose of this 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 multicore carbon fiber heater wire 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 multicore carbon fiber heater wire, comprise the power line conductor cores, the power line insulating barrier, carbon fiber exothermic part, connecting line, the heating wire inner insulation layer, the metal knitted sheath of heating wire outer insulation and heating wire, skin is coated with between the power line conductor cores of power line insulating barrier and is provided with carbon fiber exothermic part, the power line conductor cores directly is connected with carbon fiber exothermic part by the connecting line that is in staggered distribution, adjacent two connecting lines connect different power line conductor cores and carbon fiber exothermic part, the outside of power line insulating barrier and carbon fiber exothermic part coats the heating wire inner insulation layer from the inside to the outside respectively, the metal knitted sheath of heating wire outer insulation and heating wire.

Multicore carbon fiber heater wire 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, mechanism design is simple;

2, thermo-lag is little, quick heating, and heating temp is even;

3, electrical heating power is adjustable;

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, and reliable, useful life is up to more than 5 years;

6, applied environment: can in liquid and air, use.Can be applied in the liquid of industry, agricultural, civil area and air heat or the like widely.

Thereby, the utlity model has excellent popularization use value.

5, embodiment

Explain below with reference to Figure of description multicore carbon fiber heater wire of the present utility model being done.

Multicore carbon fiber heater wire of the present utility model, its structure is by power line conductor cores 1, power line insulating barrier 2, carbon fiber exothermic part 3, connecting line 4, heating wire inner insulation layer 5, the metal knitted sheath 7 of heating wire outer insulation 6 and heating wire constitutes, skin is coated with between the power line conductor cores 1 of power line insulating barrier 2 and is provided with carbon fiber exothermic part 3, power line conductor cores 1 directly is connected with carbon fiber exothermic part 3 by the connecting line 4 that is in staggered distribution, adjacent two connecting lines 4 connect different power line conductor cores 1 and carbon fiber exothermic part 3, the outside of power line insulating barrier 2 and carbon fiber exothermic part 3 coats heating wire inner insulation layer 5 from the inside to the outside respectively, the metal knitted sheath 7 of heating wire outer insulation 6 and heating wire.

When making the utility model, get two skins and be coated with the power line conductor cores 1 of power line insulating barrier 2, be situated between and insert and put a carbon fiber exothermic part 3, keeping at a certain distance away with connecting line 4 connects two power line conductor cores 1 and carbon fiber exothermic part 3 respectively, then in its outside, coat heating wire inner insulation layer 5, heating wire outer insulation 6 and the metal knitted sheath 7 of heating wire from the inside to the outside.

In the two ends of power line conductor cores 1 energized, electric current flows to carbon fiber exothermic part 3 through connecting line 4, flows out to another root power line conductor cores 1 through incorgruous connecting line 4 again, thereby forms the loop, realizes heating function of the present utility model.

Multicore carbon fiber heater wire of the present utility model, carbon fiber exothermic part 3 adopts carbon fiber knit rope, band or carbon fiber bundle; Connecting line 4 adopts metal material; All insulating barrier adopts plastics or other nonmetallic materials; The metal knitted sheath 7 of heating wire adopts metal material.Structure of the present utility model can be two cores, three cores or quadrature arrangement, and its processing and fabricating is very simple, gets final product processing and fabricating shown in the by specification accompanying drawing.

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