Abstract
The utility model relates to a novel self-temperature control cable. The novel self-temperature control cable comprises two parallel conductive wire cores and PTC conductive plastic molded at the exterior of the conductive wire cores in an extruding manner; the exterior of the PTC conductive plastic is sequentially wrapped with an insulating layer, a shielding layer and a sheath layer; and one side of the external side of the shielding layer is provided with a thermal insulation layer. By means of the above structure, the heat-emitting direction of the cable can be oriented, namely, heat generated by the cable can be transferred to a heated device in an oriented manner, and therefore, emission of heat to other directions can be decreased, and as a result, the utilization rate of the emitted heat of the cable can be improved, and thus, electric energy loss can be decreased, and an excellent energy-saving effect can be realized.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of novel temp auto-controlled cable.
Background technology
Day by day exhaustion along with science and technology development with rapid changepl. never-ending changes and improvements and resource, for adapting to policy requirements and the market demand of energy savings, every profession and trade is all being continually developed energy-conserving product, and, as the cable industry of Chinese second largest industry, its exploitation low consumption, high efficiency products are also imperative.
For the temp auto-controlled cable in current cable industry, its structure is mainly by conductor wire core, PTC conductive plastics, the compositions such as insulating barrier, screen and restrictive coating, for after cable switches on power, by PTC conductive plastics generation heat wherein, the adjusting of trip temperature and the power output of going forward side by side is controlled, thereby, to equipment transferring heat to be heated, realizes adding/accompanying the functions such as hot, antifreeze and anti-condensation.The temp auto-controlled cable is widely used in industries such as oil, chemical industry, electric power, machineries.
But simultaneous problem is with it, because the temp auto-controlled cable is mainly to utilize electric energy conversion to be heated for heat energy, and the heat produced is to cable surrounding Homogeneouslly-radiating, therefore with regard to only having caused portion of energy wherein to be directly transferred to cable is contacted, be heated on equipment, its complementary energy scatters and disappears to the rightabout that is heated equipment, cable and the ambient temperature that is heated equipment just are difficult to improve like this, perhaps cable just must carry out the continuous firing of longer time in order to reach predetermined temperature, just a large amount of consumption of the not good or electric energy of the heating properties of cable have been caused thus.
The utility model content
For overcoming above the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of orientation transmission that realizes the cable distribute heat, thereby improves the utilance of electric energy and distribute heat, the novel temp auto-controlled cable of reduction power consumption.
The technical solution of the utility model is:
A kind of novel temp auto-controlled cable, comprise two parallel conductor wire cores and the extrusion molding PTC conductive plastics outside conductor wire core, also be enclosed with successively insulating barrier, screen and restrictive coating outside the PTC conductive plastics, wherein the side in the above-mentioned screen outside also is provided with thermal insulation layer.
Above-mentioned novel temp auto-controlled cable, wherein the material of thermal insulation layer is glass fibre or aerogel blanket.
Above-mentioned novel temp auto-controlled cable, wherein also be enclosed with flame retardant coating in the outside of restrictive coating.
Above-mentioned novel temp auto-controlled cable, the cross sectional shape of cable is " D " shape that a side is smooth, opposite side is outwardly, and thermal insulation layer is near an outwardly side.
Above-mentioned novel temp auto-controlled cable, wherein the material of conductor wire core is copper or alloy material, screen is copper mesh.
The beneficial effects of the utility model are:
1, the utility model arranges thermal insulation layer by a side in the outside of the screen at cable, make the direction of cable distribute heat is carried out to orientation, heat orientation cable produced passes to the equipment of being heated, thereby reduced heat scattering and disappearing to other direction, improved the utilance of cable distribute heat, and then reduced the loss to electric energy, played significant energy-conserving action;
2, the utility model is " D " shape structure that a side is smooth, opposite side is outwardly by further cable design being become to cross sectional shape, make heated side and the heat insulation side of more easily identifying cable, constructability and installation, and the heated side that has guaranteed cable can be attached at the equipment of being heated better simultaneously, thereby further improved the utilance of cable distribute heat.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the cross section structure schematic diagram of novel temp auto-controlled cable;
Fig. 2 is novel temp auto-controlled cable " D " tee section structural representation.
In figure: conductor wire core 1, PTC conductive plastics 2, insulating barrier 3, screen 4, restrictive coating 5, thermal insulation layer 6.
Embodiment
As shown in Figure 1, a kind of novel temp auto-controlled cable, comprise two parallel conductor wire cores 1 and the extrusion molding PTC conductive plastics 2 outside conductor wire core 1, also be enclosed with successively insulating barrier 3, screen 4 and restrictive coating 5 outside PTC conductive plastics 2, wherein the side in above-mentioned screen 4 outsides also is provided with thermal insulation layer 6.As a kind of preferred, wherein the material of thermal insulation layer 6 is glass fibre or aerogel blanket, and the material of conductor wire core 1 is copper or alloy material, and screen 4 is copper mesh.
The said structure production technology is simple, with low cost, and the side by screen 4 outsides at cable arranges thermal insulation layer 6, make the direction of cable distribute heat is carried out to orientation, heat orientation cable produced passes to the equipment of being heated, thereby reduced heat to the scattering and disappearing of other direction, and improved the utilance of cable distribute heat, and then reduced the loss to electric energy, played significant energy-conserving action.
As further preferred, above-mentioned novel temp auto-controlled cable, the cross sectional shape of cable is " D " shape that a side is smooth, opposite side is outwardly, and thermal insulation layer 6 is near an outwardly side.By being designed to this structure, make heated side and the heat insulation side of more easily identifying cable, constructability and installation, and guaranteed that the heated side of cable can be attached at the equipment of being heated better simultaneously, thus further improved the utilance of cable distribute heat.
As further preferred, above-mentioned novel temp auto-controlled cable, wherein also be enclosed with flame retardant coating in the outside of restrictive coating 5, with fire resistance and the safe operation that further guarantees this cable.
The above is explained in detail the preferred embodiment of the utility model and embodiment by reference to the accompanying drawings, but the utility model is not limited to the above-described embodiment and examples, in the ken possessed those skilled in the art, can also make without departing from the concept of the premise utility various variations.
