Description

Carbon fiber multicore combined electrical hot line

Technical field

The utility model relates to a kind of electrical heating elements, a kind of specifically carbon fiber multicore combined electrical hot line.

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.

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 carbon fiber multicore combined electrical hot line of no visible light in the course of work.

The technical scheme that its technical problem that solves the utility model adopts is: this carbon fiber multicore combined electrical hot line, its structure is by the power line conductor cores, the power line insulating barrier, carbon fiber exothermic part, bounding wire, the heating wire inner insulation layer, the metal knitted sheath of heating wire outer insulation and heating wire is formed, 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 bounding wire that is in staggered distribution, adjacent two bounding wires connect different power line conductor cores and carbon fiber exothermic part, the outside of power line insulating barrier and carbon fiber exothermic part is coated with 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.

Carbon fiber multicore combined electrical hot line of the present utility model is compared with prior art, the beneficial effect that is had is 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, 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.
