Abstract
The present invention relates to a temperature autocontrol heat generating composite pipe which orderly comprises an inner plastic pipe, a first-layer metallic pipe, a pipe of a macromolecular PTC material, a second-layer metallic pipe and an outer plastic pipe from inside to outside, wherein the inner plastic pipe and the first-layer metallic pipe are bonded with a hot-melt adhesive, the outer plastic pipe and the second-layer metallic pipe are bonded with the hot-melt adhesive, and the two layers of metallic pipes are respectively connected with power supply leads. When the metallic pipes positioned inside and outside the PTC pipe are electrified, electric energy can be converted into heat energy by the pipe of a macromolecule PTC material. The heating function of a PTC material is completely controlled by the environmental temperature; when the environmental temperature or heat generated by the PTC material self reaches or surpasses a certain critical temperature, the resistance of the material is suddenly increased to cause the fall of the powder of heat generation; and therefore, the aim of automatically controlling the temperature is achieved. The composite pipe has the advantages of simple structure and convenient use, and can be used for many places, such as families, hotels, etc. When hot water needs to be used, the hot water, the temperature of which is automatically controlled, can be obtained by connecting a power supply without installing a heater.
Description
Technical field
The present invention relates to compound pipe, relate to composite pipe specifically from the temperature control heating.
Background technique
In recent years, a large amount of aluminium-plastic composite pipes that use have excellent mechanical property, decay resistance, safe and sanitary performance, advantages such as heat preservation and insulation and light weight.Its inside and outside layer is for moulding pipe, and central core is an aluminum pipe, internal plastic tube and moulding outward manage and aluminum pipe between use hot melt adhesive bonding respectively, this aluminium-plastic composite pipe is simple aqueduct, provides hot water then to need to install water heater.
Summary of the invention
The purpose of this invention is to provide a kind of automatic tomperature controlled heating composite pipe.
Automatic tomperature controlled heating composite pipe of the present invention from the lining outwards successively by internal plastic tube, first layer metal tube, high molecular PTC tubes of material, second layer metal pipe and outside mould pipe and be composited, wherein, internal plastic tube and first layer metal tube and outer moulding between pipe and the second layer metal pipe use hot melt adhesive bonding respectively, and the double layer of metal pipe respectively is connected with power supply lead wire.
Because the conductive polymer ptc material has the resistance positive temperature coefficient effect, its specific resistance raises with temperature and increases, its specific resistance presents the sudden change of the order of magnitude near critical temperature, be a kind of from the temperature control heater, therefore when being positioned at the PTC pipe, when outer metal tube is connected power supply, utilize the high molecular PTC tubes of material electric energy can be converted into heat energy, and its heating function is controlled by ambient temperature fully, when ambient temperature or self-heating temperature meet or exceed a certain critical temperature, the resistance of material increases suddenly, cause that heating power descends, thereby can reach the purpose of A.T.C.Composite pipe structure of the present invention is simple, easy to use, can be used for numerous occasions such as family, hotel, when needing with hot water, as long as connect with the mains, need not to install heater, just can obtain temperature automatically controlled hot water.
Description of drawings
Accompanying drawing is the structural representation of automatic tomperature controlled heating composite pipe of the present invention.
Embodiment
With reference to accompanying drawing, automatic tomperature controlled heating composite pipe of the present invention from the lining outwards successively by internal plastic tube 1, first layer metal tube 2, high molecular PTC tubes of material 3, second layer metal pipe 4 and outside mould pipe 5 composite co-extruding moulding, wherein, internal plastic tube and first layer metal tube and outer moulding between pipe and the second layer metal pipe use hot melt adhesive bonding respectively, and the double layer of metal pipe respectively is connected with power supply lead wire 6.The double layer of metal pipe can adopt aluminum pipe.The temperature of hot water can be selected according to the kind difference of PTC heat generating material, for example can select the PTC heat generating material of low density polyethylene and carbon black compound system for use, or select the PTC heat generating material of high density polyethylene (HDPE) and carbon black compound system for use, when the PTC heat generating material of selecting low density polyethylene and carbon black compound system for use, the temperature of hot water is 60 ℃, and select the PTC heat generating material of high density polyethylene (HDPE) and carbon black compound system for use, then the temperature of hot water is 80 ℃.Internal plastic tube and mould pipe outward and can adopt crosslinked high density polyethylene (HDPE).
