Abstract
The utility model provides a three core winding type carbon fiber accompanying heat cable, belonging to the electric heating element. The structure comprises power supply conducting wires, carbon fiber heater wires and an outer insulation layer. Two power supply conducting wires and the carbon fiber heater wires are spirally winded together. The cross section of the power supply conducting wire presents the triangular distributing. The electric parts of the two power supply conducting wires are respectively and directly connected with the carbon fiber of the carbon fiber heater wires by connection lines. The two close connection lines are respectively connected with the different power supply conducting wires and the carbon fiber heater wires. The outer insulation layer is arranged on the outer sides of the power supply conducting wires and the carbon fiber heater wires. Compared with the prior art, the three core winding type carbon fiber accompanying heat cable of the utility model has the characteristics of simple structure, long service life, high conversion efficiency of the electricity and the heat, broad operating temperature range, etc. and does not have the visible light in the operating process.
Description
1, technical field
The utility model relates to a kind of electrical heating elements, a kind of specifically three core winding type carbon fiber accompanying heat cables.
2, background technology
As everyone knows, the heater wire under the prior art mostly uses nichrome, molybdenum filament, copper wire, 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, copper wire, 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
Technical assignment of the present 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, three core winding type carbon fiber accompanying heat cables 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 three core winding type carbon fiber accompanying heat cables, comprise power lead, carbon fiber heater wire and outer insulation, two power leads and the carbon fiber heater wire of cross section distribution triangular in shape are spirally wound on together, the current-carrying part of two power leads directly links to each other by the carbon fiber of connecting line with the carbon fiber heater wire respectively, adjacent two connecting lines connect different power leads and carbon fiber heater wire respectively, and the arranged outside of power lead and carbon fiber heater wire has outer insulation.
Two power leads that the spiral of cross section distribution triangular in shape twines and carbon fiber heater wire center are provided with one and strengthen lifting-line.
Three core winding type carbon fiber accompanying heat cables of the present utility model are compared with prior art, have 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, electric property is stable, and reliable, useful life is up to more than 5 years;
4, applied environment: can be applied in the air of industry, agricultural, civil area and liquid heat or the like widely.
Thereby, the utlity model has excellent popularization use value.
4, description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the structural representation of three core winding type carbon fiber accompanying heat cables;
Accompanying drawing 2 is the cross section structure schematic diagram of three core winding type carbon fiber accompanying heat cables;
Accompanying drawing 3 is that three core winding type carbon fiber accompanying heat cables do not have the cross section structure schematic diagram of strengthening lifting-line.
5, embodiment
Explain below with reference to Figure of description three core winding type carbon fiber accompanying heat cables of the present utility model being done.
Three core winding type carbon fiber accompanying heat cables of the present utility model, its structure comprises power lead 1, carbon fiber heater wire 2 and outer insulation 4, being spirally wound on together of two power leads 1 of cross section distribution triangular in shape with carbon fiber heater wire 2, the current-carrying part of two power leads 1 directly links to each other with the carbon fiber of carbon fiber heater wire 2 by connecting line 3 respectively, adjacent two connecting lines 3 connect different power lead 1 and carbon fiber heater wire 2 respectively, and the arranged outside of power lead 1 and carbon fiber heater wire 2 has outer insulation 4.
Two power leads 1 that the spiral of cross section distribution triangular in shape twines and carbon fiber heater wire 2 centers are provided with one and strengthen lifting-line 5.
When making the utility model, get two power leads 1 and a carbon fiber heater wire 2, it is spirally wound on a skin is coated with on the reinforcement lifting-line 5 of outer insulation, the insulating barrier of strip off power lead 1 and carbon fiber heater wire 2 at a certain distance then, directly connect the current-carrying part of two power leads 1 and the carbon fiber of carbon fiber heater wire 2 with connecting line 3, coat last layer outer insulation 4 in the outside of two power supplys 1 and carbon fiber heater wire 2 at last.
During use, with 1 liang of termination electricity of power lead, electric current arrives carbon fiber heater wire 2 through power lead 1 through connecting line 3, is flowed out by another root power lead 1 by adjacent connecting line 3 to form the loop again, and finishes the energising heating function of carbon fiber simultaneously.
Three core winding type carbon fiber accompanying heat cables of the present utility model, it is strengthened lifting-line 5 and plays the effect that strengthens intensity, also can not add setting, as shown in Figure 3, strengthens wire or strands of metal wire rope that lifting-line 5 can be tape insulation.
Three core winding type carbon fiber accompanying heat cables of the present utility model, 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.
