Abstract
The invention discloses a novel self-temperature-limiting heating cable. The novel self-temperature-limiting heating cable is characterized in that the cross section of the heating cable is of a tubular structure defined by a heating core band, three electrical conductors are arranged in the heating core band, and the electrical conductors are connected to a power supply. The novel self-temperature-limiting heating cable has the advantages that seamless fit between the novel self-temperature-limiting heating cable and heating pipelines is guaranteed, thermal conductivity is improved, function expansion can be carried out conveniently, and the novel self-temperature-limiting heating cable can be applied to industrial three-phase occasions.
Description
Technical field
The present invention relates to the fields such as freezing prevention tubing, particularly a kind of novel temperature of limit certainly heating cable.
Background technology
Frequent can the freezing because temperature is too low of various pipes in winter, can be by frost crack pipe when serious, have a strong impact on resident's daily life and industrial production.
The current cross section of certainly limitting warm heating cable is platypelloid type banded structure, is not easy to install or attaches bad while causing it to be applied to some occasion, and only has two conductor structures, is not easy to be applied in industrial three-phase electricity occasion.
For the problems referred to above, a kind of novel temperature of limit certainly heating cable is provided, seamless applying at assurance and water back, when improving pyroconductivity, being convenient to carry out Function Extension is the problem that prior art need to solve.
Summary of the invention
Technical problem to be solved by this invention is, a kind of novel temperature of limit certainly heating cable is provided, and guaranteeing with water back seamless applyingly, when improving pyroconductivity, is convenient to carry out Function Extension.
For achieving the above object, technical scheme of the present invention is, a kind of novel temperature of limit certainly heating cable, it is characterized in that: the cross section of described heating cable is that heating core band surrounds tubular, hollow structure, the inside of heating core band is provided with two or more conduction conductors, and conduction conductor is connected on power supply.
Described heating core band inside can wrap water back.
Solid-core packing can be wrapped up in described heating core band inside.
Described heating core band can be the tubular structure of Unseal type.
Described conduction conductor is uniformly distributed in heating core band.
Described heating core band is PTC heating element
The novel temperature of a limit certainly heating cable, owing to adopting above-mentioned structure, the invention has the advantages that: 1, assurance and water back are seamless applying, improves pyroconductivity; 2, be convenient to carry out Function Extension; 3, can be applied to industrial three-phase electricity occasion.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation;
Fig. 1 is that a kind of novel warm heating cable of certainly limitting of the present invention is provided with the structural representation of three conduction conductors;
Fig. 2 is that a kind of novel warm heating cable of certainly limitting of the present invention is provided with the structural representation of two conduction conductors;
Fig. 3 is that a kind of novel warm heating cable of certainly limitting of the present invention is the structural representation of the tubular structure of Unseal type;
Fig. 4 is the structural representation of existing heating cable;
In Fig. 1-2,1, heating core band; 2, conduction conductor.
Embodiment
As shown in Figure 1, cross section of the present invention is that heating core band 1 surrounds tubular, hollow structure, and the inside of heating core band 1 is provided with two or more conduction conductors 2, and conduction conductor 2 is connected on power supply.Heating core band 1 can be also the tubular structure of Unseal type, is convenient to site operation, and pipeline is snapped in.Seamless applying with heated pipeline, greatly reduce energy waste, efficient energy-saving is significant.Inside can prefabricated upper pipeline, is convenient to install and use and install.When inside is solid-core packing, be the warm heating cable of circular limit certainly, be convenient to the applications that some needs circular heating cable.
Heating core band 1 inside can wrap water back, realizes seamless applying.
The inside of heating core band 1 has can wrap up solid-core packing too,, to other heating places its function is expanded as an overall applicability.
The present invention adopts circular configuration, and realization and heated pipeline are seamless applying, and it is maximum that heat conduction efficiency reaches; Three cores or multicore structure can be realized the direct use of industrial three-phase electricity, have initiative and significance.Wherein, three core main features are to directly apply to industrial three-phase electricity, have very important breakthrough and actual application value, and a lot of industrial occasions do not have 2 220 voltages.
Contrast in conjunction with Fig. 2, the existing flat structure from the warm heating cable of limit, while causing it to be applied to the occasions such as pipeline heating and the laminating such as heated pipeline bad, there is gap, the present invention can be directly will be heated pipeline heating core band 1 on extrusion molding aborning, complete and seamless applying, heat conduction efficiency is the highest, and has saved the set-up time.And existing only have two conductor structures from limit temperature, is not easy to be applied in industrial three-phase electricity occasion, and this structure energy perfection addresses this problem, and greatly expands and improve existing product and purposes.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted technical solution of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
