Abstract
The present utility model discloses a heater which comprises a heater main body, a heating wire and a power line. The power line comprises a PFA layer and a conductive metal wire wrapped by the PFA layer. The heating wire is arranged on the heater main body, one end of the power line is connected with a power supply, and the other end is electrically connected with the heating wire. Through the plastic packaging method, the conductive metal wire is wrapped by the PFA, the PFA layer is directly formed outside the conductive metal layer, thus no gap exists between the PFA layer and the conductive metal wire, air can be prevented from entering into a gap between the PFA and the conductive metal wire, when the heater is working, the air will not be heated and expanded, the external steam or liquid can be prevented from entering, service life of the power line can be prolonged, and safety of the heater can be enhanced.
Description
Technical field
The utility model relates to photovoltaic cleaning equipment and electroplating device field, particularly a kind of heater.
Background technology
The disc type Teflon heater that uses in the photovoltaic cleaning machine preheating bucket at present is mainly used in heating the liquid or the pure water that contain soda acid.In order to protect the power line of heater, method commonly used is at PFA(Polyfluoroalkoxy of wire overcoat, tetrafluoroethene-perfluorinated alkoxy vinyl ether copolymer) pipe.The PFA material is the copolymer of a small amount of perfluoro propyl vinyl ether and polytetrafluoroethylene.Long-term serviceability temperature is-80 ℃ ~ 260 ℃, and good chemical resistance is arranged, and all corrosion-resistant to all chemicals, coefficient of friction is minimum in plastics, also has good electrical property, and its insulating properties is temperature influence not.Can be used for making corrosion barrier, seal, insulating part and high temperature electric wire etc.Because will inevitably there be the space in the mode that this wire is inserted in the PFA pipe during making, cause PFA pipe internal memory that air is arranged.In heater work, the air expanded by heating in the PFA at the power line position pipe so that the connecting portion of PFA pipe produces leak, causes outside steam to enter in the PFA pipe.Therefore, after use a period of time, the PFA pipe at power line position will accumulate some steam, not only can shorten the useful life of power line, and so that there is the potential safety hazard of electric leakage in heater.
The utility model content
The purpose of this utility model is to provide a kind of novel heater.
According to one side of the present utility model, a kind of heater is provided, comprise heater body, heater strip and power line.Power line comprises the conductive wire of PFA layer and PFA layer parcel.Heater strip is arranged on the heater body.One end of power line is connected with power supply, and the other end is electrically connected with heater strip.Utilize plastic mode, allow PFA wrap up conductive wire, directly outside conductive wire, form a PFA layer, so that there is not the space between PFA and the conductive wire, prevent that air from entering between PFA and the conductive wire, so that outside steam or liquid enter wherein, prolong the useful life of power line because of the air expanded by heating when avoiding heater work, improved the fail safe of heater.
In some embodiments, conductive wire is the wire of copper wire, aluminium wire or filamentary silver or other conductions.
In some embodiments, heater strip in the shape of a spiral.This spiral helicine design, intensity is good, and good heat dissipation effect is easy to make, and is easy to operate.
In some embodiments, heater strip comprises internal layer and skin.Internal layer is copper cash, and skin is PFA.Adopt plastic mode, allow the PFA material directly wrap up copper cash, avoid the direct contact liq of copper cash, prevent heater strip by liquid corrosion and impaired getting rusty.
In some embodiments, be arranged with the PFA pipe outside the junction of heater strip and power line.Further protection heater strip and power line prevent that steam and liquid from entering.
Description of drawings
Fig. 1 is the overall schematic of the heater of a kind of execution mode of the utility model.
Fig. 2 is the profile of the power line of Fig. 1 heater.
Fig. 3 is the structural representation of the heater strip of Fig. 1 heater.
Fig. 4 is the profile of Fig. 3 heater strip.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 to Fig. 4 has schematically shown the heater according to a kind of execution mode of the utility model.
This heater comprises heater body 1, heater strip 2 and power line 3.Heater body 1 is in the form of annular discs.Power line 3 comprises the many conductive wires 302 of PFA layer 301 and PFA layer 301 parcel.This conductive wire 302 is copper wire.Heater body 1 is provided with a plurality of through holes 101, and heater strip 2 is wrapped on the heater body 1 by through hole 101.One end of power line 3 is connected with power supply, and the other end is electrically connected with heater strip 2.Heater strip 2 integral body and comprise internal layer 202 and outer 201 in the shape of a spiral, and internal layer 202 be copper cash, and skin 201 is PFA.Outside the junction of heater strip 2 and power line 3, be arranged with PFA pipe 102.
By plastic mode so that heating wire and copper cash be sealed, detailed process is: utilize fluorine to mould extruder, first copper wire or copper cash are fixed on the machine, copper wire or copper cash level move ahead during machine run, the PFA raw material through gone out shower nozzle by the screw rod rotary squeezing after the extruder heating and be attached to copper wire or copper cash on, after cooling, finish.After above-mentioned plastic mode is processed, allow PFA wrap up copper wire, directly outside copper wire, form a PFA layer 301, so that there is not the space between PFA and the copper wire, prevent that air from entering between PFA and the copper wire, so that outside steam or liquid enter in the power line 3, prolong the useful life of power line 3 because of the air expanded by heating when avoiding heater work, improved the fail safe of heater; Equally, adopt above-mentioned plastic mode, allow the PFA material directly wrap up copper cash, avoid the direct contact liq of copper cash, prevent heater strip 2 by liquid corrosion and impaired getting rusty; Heater strip 2 in the shape of a spiral, this spiral helicine design, intensity is good, good heat dissipation effect is easy to make, and is easy to operate; PFA pipe 102 can further be protected heater strip 2 and power line 3, prevents that steam and liquid from entering.
Above-mentioned only is preferred embodiment of the present utility model; without departing from the concept of the premise utility; the appropriate change that the those of ordinary skill of the industry is made, for example conducting metal 302 can for the wire of aluminium wire or filamentary silver or other conductions, all belong to protection range of the present utility model.
