Description
Technical field
The present invention relates to heating cable fields, can heat cable more particularly to a kind of multilayer inner core.
Background technique
Heat cable mainly life heating, plant culture, the wire and cable of pipe insulation etc..Heating cable is to use
Single or more heating alloy makees thermal conductive insulator, seamless company as pyrotoxin, high-purity, high temperature, electric smelting crystal magnesium oxide
Continuous stainless steel or copper pipe are fabricated as sheath using special producing technique.Have deep-etching act on place can additional PE or
The housing of low smoke and zero halogen.
Heating cable heat why it is referred to as winter optimal heating system, be not only only that it economy, safety,
Convenient, high-quality, and be it and, using people as the main body of life, highlight the master of this comfortable, healthy, environmentally friendly three big modern life
Topic；The human oriented design of height, simple, flexible control mode bring great convenience to user；It is hidden in subsurface
System structure saves the interior space to the maximum extent.
Since radiant heat transfer conducts heat instead of cross-ventilation, reduce the dust flown upward in air, since wall is omitted
On radiator avoid the peculiar smell that the paint of spreader surface generates without the corner sheltered evil people and countenance evil practices, dry ground from
This has taken leave of the worry because of moist bring cockroach, damp worm, with fresh air pleasant from this in room.
Since aluminium shielding has blocked harmful electromagnetic radiation, there is no any harm to human body, through national CAS Institute of Physics to fever
The electromagnetic radiation test result of cable show system generate electromagnetic radiation be only geomagnetic field amount of electromagnetic radiation 30/
One, it can be ignored, be real green product.There is no noise pollution in the operation of heating cable heating system, lives
Environment is very quiet.
Heating cable heating system, is not limited by environmental condition, can be in any place for having heating demands, it can be with
Wall or ceiling can also be installed on by being installed on ground, can be rooms, can also be carried out anti-freezing and heat-insulating to pipeline, may be used also
To carry out the deicing or snow melting of outdoor road surface, roof.Especially for house (such as club, exhibition center, cinema, the body of larger space
Educate shop etc.), the heat transfer distances of wall radiator are limited, are difficult to meet the heating requirement of the entire interior space, and Indoor Thermal
Amount is unevenly distributed, and for the terrestrial surface radiation heating method of heating cable using entire ground as radiator, indoor temperature distribution is uniform,
In any position in room, can all there be cosy feeling, for the volumed space building of glass curtain wall structure, due to radiator
It can not be mounted on the wall, be more suitable for that heating cable heating system is installed.
Above-mentioned is the advantage of heatable cable, still, for heating the production cost of cable and being laid with cost very
Height, the structure for how efficiently using cable itself achieve the purpose that saving production cost, become the direction of the prior art.

Expect characteristic energy storage, discharges amount of heat, it, can as the cable of coating using phase-change material in the identical situation of consumption electric energy
More thermal energy are provided.The present invention meets heating requirements in the least situation of materials, has saved production material.
Specific embodiment
The present invention is that a kind of multilayer inner core can heat cable, which is characterized in that including internal layer from inside to outside, middle layer and outer
Layer；
The internal layer includes two identical inner cores, each inner core is followed successively by hollow insulating layer from inside to outside, is in
Cable conductor, the heat insulating coat of existing helical arrangement；It is fitted closely between former and later two spirals of the cable conductor；The inner core is cut
Face is circle, and the heat insulating coat of adjacent inner core has laminating points；
The middle layer is protective layer, and being wrapped in is flame-retardant layer between inner core, and it is successively respectively to shield that flame-retardant layer rises outward
Protective layer and phase-change material layers；
The outer layer is followed successively by ground line layer and shell from inside to outside.
The hollow insulating layer is insulating materials, and wherein pericardium includes several through conducting wire and equally distributed through-hole.This
A little through-holes are effectively reduced the self weight of cable, but will not destroy whole structure, while can reduce the use of insulating materials
Material, achievees the purpose that save the cost.
The phase-change material layers include two layers, and one layer is sprayed at except shielding protection layer, and one layer is sprayed in ground line layer
Side；It is fitted closely between two layers of phase change material coating.Phase-change material layers can utilize itself according to the temperature change of surrounding
Material property energy storage discharges amount of heat, the cable energy in the identical situation of consumption electric energy, using phase-change material as coating
More thermal energy are enough provided.
The shielding protection layer is aluminum foil shielded protective layer.Two kinds of rubber layers, as the highest two kinds of materials of cost performance,
It can be used as most preferably, but not only limit two kinds of materials, the rubber layer of all approximate effects can be used as fire-retardant layer material.
The shell is transparent insulation material, with a thickness of 0.5mm, it is ensured that insulation safety.
Phase-change material has the ability for changing its physical state in certain temperature range.By taking solid-liquid phase change as an example,
When being heated to fusion temperature, the phase transformation from solid-state to liquid is just generated, during fusing, phase-change material is absorbed and stored a large amount of
Latent heat；When phase-change material is cooling, the heat of storage will be dispersed into environment within the scope of certain temperature, be carried out from liquid
State is to solid reverse transformation.In both phase transition process, stored or release energy is known as latent heat of phase change.Physical state hair
When changing, the temperature of material itself almost remains unchanged before phase transformation is completed, and a wide temperature platform is formed, although temperature
It is constant, but the latent heat for absorbing or discharging is quite big.So can be used as type cable most preferably.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
