Embodiment
Embodiment one
As illustrated in fig. 1 and 2, a kind of pipeline being used for medium heating, heating the tube wall of pipeline includes the corrosion-resistant of internal layer
The insulating protective layer 6 of layer 1 and outer layer, the polyimide film being additionally included between the anti-corrosion layer 1 and the insulating protective layer 6
2 and second electric heating layer 5.The Kapton helically formula be wound in the anti-corrosion layer and the insulating protective layer it
Between.Second electric heating layer 5 is formed by continuous conductive laminated heating material.In the outer surface of the Kapton 2
On be etched with form positive and negative electrode the first bonding jumper 3 and the second bonding jumper 4, the first bonding jumper 3 and the second bonding jumper 4 are with polyamides
Helically formula is wound imines film, and length direction spiral wrap of the Kapton 2 with bonding jumper along pipeline
Extension.First bonding jumper 3 and the second bonding jumper 4 are all in close contact with second electric heating layer 5, so that Kapton
2 make the second electric heating layer 5 produce heat when forming shunt circuit between the bonding jumper 4 of the first bonding jumper 3 and second respectively.
When applying certain voltage between the first bonding jumper 3 and the second bonding jumper 4, in the first bonding jumper 3 and second
Electric current can be produced in polyimide film 2 between bonding jumper 4.Due to second between the first bonding jumper 3 and the second bonding jumper 4
Electric heating layer 5 has certain resistance, therefore heat will be produced when there is electric current to flow through the second electric heating layer 5, so as to pair plus
Pipe line is heated, and the liquid for preventing from heating in pipeline freezes.
In this embodiment, because the second electric heating layer 5 is formed by continuous conductive laminated heating material, therefore can be with
The mode of face heating is uniformly heated up to anti-freezing pipeline.
Bonding jumper is copper foil in the present embodiment.
Rock wool heat-preservation layer can be increased between the middle level and outer layer as needed.
Embodiment two
If Fig. 3 and Fig. 4 are to show the second embodiment for heating pipeline of the invention.First electric heating layer completely by
Double-deck polyimide film 2 and wherein the first bonding jumper of the composition positive and negative electrode of the interior lateral erosion of a strata imide membrane and
Second bonding jumper is formed, and has no the second electric heating layer 5.The other structures of the embodiment are identical with the first embodiment of the present invention.
In the second embodiment of the present invention, when one end between the bonding jumper 4 of the first bonding jumper 3 and second applies one
During fixed voltage, then the first bonding jumper 3 is connected with the other end of the second bonding jumper 4 when producing loop, the first bonding jumper 3 and second
Polyimide film 2 between bonding jumper 4 will produce certain resistance, thus produce heat, so as to add to heating pipeline
Heat, the liquid medium for preventing from heating in pipeline freeze.
In this embodiment, because polyimide film 2 is that the mode angled with corrosion-resistant pipeline is spirally wound on
Formed, therefore heating pipeline can be heated in a manner of face is heated on the anti-corrosion layer 1.
Bonding jumper is copper alloy bar in the present embodiment.
It will be understood by those skilled in the art that according to the Computing Principle of the total resistance value of series resistance, the present invention
Heating pipeline it is longer, the total electricity formed between the first bonding jumper 3 (copper alloy bar) and the second bonding jumper 4 (copper alloy bar)
Resistance is bigger, and total heating power is also just smaller.Therefore can be according to the length for being actually needed selection heating pipeline, to obtain
Desired heating effect.
Rock wool heat-preservation layer can be increased between middle level and outer layer as needed.
The heating making of pipeline, processing efficiency will be substantially improved in the proposition of the present invention, and effectively reduce zone of heating or
It is too big that clad because of winding resistance wire or positive and negative polarity wire deviates former relative position, and caused percent defective, can also avoid because
Resistance wire and wire because winding problem snap into together caused by short circuit problem.
Embodiment described above is only that the preferred embodiment of the present invention is described, and not the scope of the present invention is carried out
Limit, on the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art make to technical scheme
Various modifications and improvement, all should fall into claims of the present invention determination protection domain in.
