Abstract
The utility model discloses a temperature automatic controlled heating pipe, which comprises a column-shaped heating core (1), a tube-shaped high temperature resistant isolating layer and a tube-shaped outer casing (3). The tube-shaped outer casing (3), the high temperature resistant isolating layer and the heating core (1)are covered from outer to inner in sequence; electrodes (4) are arranged on the heating core (1), a conducting wire (5) is connected with the electrodes (4). The automatic controlled heating pipe of the utility model can realize the automatic temperature controlling function, thus, the energy saving effect is achieved.
Description
Technical field
The utility model relates to a kind of heater element, and is particularly a kind of from the temperature control heating tube.
Background technology
Existing heating tube is made up of heater strip, inorganic insulation layer and metal shell etc.Because heater strip is to adopt the electrothermal alloy of heating line Cr20Ni80 and so on to combine, therefore not from temperature controlling function.During actual the use, this kind heating tube is easy to generate the part and burns out; Cause heating unstable, thereby influence heats.Its main cause is that the temperature coefficient of resistance of this exothermic material of Cr20Ni80 is minimum, and made heat-generating pipe power can not change with variation of temperature; Therefore when heating, be prone to the phenomenon of local overheating, can not reach effect in energy saving and environmental protection.In addition, when the required constant temperature in certain heating field, heating tube is continuous therewith then also to need to dispose in addition 1 thermostat, could form the complete instrument of a cover; This not only makes a whole set of instrument become complicated, returns to use and operate and make troubles, and also is unfavorable for carrying.
The utility model content
The technical problems to be solved in the utility model provides a kind of from the temperature control heating tube, and this kind heating tube can be realized the function from temperature control, thereby reaches energy-saving effect.
In order to solve the problems of the technologies described above, it is a kind of from the temperature control heating tube that the utility model provides, and comprises the temperature-resistant insulation layer and the tubular housing of columniform heating core, tubulose, and shell, temperature-resistant insulation layer and heating core interlock from outside to inside successively; Heating core is provided with electrode, and lead links to each other with electrode.
As the improvement from the temperature control heating tube of the present utility model: temperature-resistant insulation layer comprises magnesium oxide packed layer and at least 2 s' high temperature insulation bar, and high temperature insulation bar and heating core are fixedly linked, and the magnesium oxide packed layer is arranged between per 2 high temperature insulation bars.
As the further improvement from the temperature control heating tube of the present utility model: temperature-resistant insulation layer comprises 3 high temperature insulation bars, and the high temperature insulation bar is fixedly linked with heating core symmetrically.
As the further improvement from the temperature control heating tube of the present utility model: heating core is the heating core of being made by ptc material; This ptc material can be ceramic ptc material, also can be the high molecular PTC material.
As the further improvement from the temperature control heating tube of the present utility model: shell is the housing of being made by metal material, and this metal can be copper, stainless steel, aluminium or the like.
Of the present utility model from the temperature control heating tube, adopted the heating core of making by ptc material.Because PTC (Positive temperature coefficent) material is a kind of emerging material, has electric positive temperature coefficient effect, its resistivity raises with material temperature and increases; Therefore when material temperature reached a certain temperature, its resistance sharply increased, and material is state of insulation, and when material temperature descended, its resistance reduced gradually, and recovered its conductivity.Therefore, of the present utility modelly can realize temperature automatically controlled function, thereby reach the effect of high-efficient energy-saving environment friendly from the temperature control heating tube.According to the difference of ptc material, the heating-up temperature scope from the temperature control heating tube of the present utility model is at 10～200 ℃.
Of the present utility model from the temperature control heating tube, its shell is made of metal, therefore the highest withstand voltage 20 atmospheric pressure that reach.By the temperature-resistant insulation layer that high temperature insulation bar and magnesium oxide packed layer are formed, really realized dual-use function high temperature resistant and insulation, guaranteed good security performance.Symmetrically arranged high temperature insulation bar can guarantee that the center of circle of heating core and the center of circle of shell coincide.Lead can adopt heat-resisting silicone rubber wire, therefore has the advantage of good heat resistance.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the main TV structure schematic diagram of the partial cutaway from the temperature control heating tube of the present utility model;
Fig. 2 is the enlarged diagram of the A-A section among Fig. 1.
Embodiment
Fig. 1 and Fig. 2 are a kind of from the temperature control heating tube in conjunction with having provided, and comprise the temperature-resistant insulation layer and the tubular housing 3 of columniform heating core 1, tubulose, the identical length of heating core 1, temperature-resistant insulation layer and shell 3 etc.; Heating core 1 is the heating core of being made by ceramic ptc material, and shell 3 is housings made of aluminum.This temperature-resistant insulation layer is made up of magnesium oxide packed layer 22 and 3 high temperature insulation bars 21, and the inner 211 of each high temperature insulation bar 21 matches with the circumferential surface of heating core 1, outer end 212 matches with the inner surface of shell 3.
Adopt heat-resistant adhesive to be fixed on the circumferential surface of heating core 1 the inner 211 of each high temperature insulation bar 21 at first respectively, and these 3 high temperature insulation bars 21 are positioned on the circumferential surface of heating core 1 symmetrically.Inner surface at shell 3 scribbles the very thin thermosetting epoxy resin of one deck equably, and then shell 3 is enclosed within tightly on the outer end 212 of high temperature insulation bar 21; Promptly make and clip the thermosetting epoxy resin layer that one deck seals tightly between the inner surface of shell 3 and the outer end 212.At last magnesium oxide is filled to by in heating core 1, shell 3 and per 2 the high temperature insulation bars 21 formed spaces tightly, thereby forms magnesium oxide packed layer 22.So just realized with shell 3, temperature-resistant insulation layer and heating core 1 from outside to inside successively the cover connect together.Be fixed with electrode 4 on the end face of heating core 1, lead 5 links to each other with electrode 4.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection range of the present utility model.
