Existing superaudio induction heating equipment due to device volume larger, mostly all be arranged on fixing position, the heating of limited position and angle can only be carried out, thus can not be applied among the multiple industries such as such as auto repair, road and rail maintenance and construction, can not be applied in domestic life field, and existing superaudio induction heating equipment also has the problems such as the complicated and efficiency of circuit is low, limits the practical value of equipment.
At present, superaudio induction heating technique is with efficiently, clean, many merits such as environmental protection and being widelyd popularize in energy industry rapidly.It meets environmental protection and sustainable development policy, is one of environmental type heating process.Tradition superaudio induction heating equipment is mainly applied with industrial processes, has manufacturing cost high, the defects such as plant maintenance is difficult.
Summary of the invention
Object of the present invention is just to provide a kind of superaudio induction line with heating function, to solve the problem that circuit is complicated, efficiency is low and application surface is narrow that existing superaudio induction heating equipment exists.
The present invention is achieved in that a kind of superaudio induction line with heating function, comprises metal core wire, inner insulating layer, copper coiling, external insulation layer, screen and sheath; Described inner insulating layer is coated on the outer surface of described metal core wire, described copper coiling is wrapped on the described inner insulating layer of described metal core wire outside along the axial screw of described metal core wire, described external insulation layer is coated on the outer surface of described inner insulating layer, and described copper coiling is wrapped between described inner insulating layer and described external insulation layer, described screen is coated on the outer surface of described external insulation layer, and described insulating sleeve is coated on the outer surface of described screen; The two ends of described copper coiling are for connecting the both positive and negative polarity of high frequency electric source; The two ends of described metal core wire are fixed together, and form closed metal core wire closed loop.
Described screen is the screen net structure made with wire.
The present invention is as a kind of novel electric heating line with heating function, what adopt is induction heating principle, the copper coiling at line with heating function two ends connects with the positive and negative electrode of high frequency electric source, and copper coiling itself does not produce heat, just under the effect of high-frequency current, form stronger high frequency magnetic field, electric current is larger, and magnetic field intensity is higher.Metal core wire in copper coiling spiral winding is under the effect of this high frequency magnetic field, produce induced current, particularly be fixed together at the two ends of metal core wire, under the state forming a closed metal core wire closed loop, under faradic effect, electricresistance effect, hysteresis effect, skin effect and edge effect etc. will be utilized, in metal core wire, produce a large amount of heats, temperature is raised rapidly, thus forms the superaudio induction line with heating function of a high heating and Fast Heating.
Can work as long as line with heating function of the present invention applies a superaudio power supply in use, the copper coiling of energising is not directly generated heat, and can not produce easy phenomenon of blowing as electric furnace heating wire, useful life can extend greatly.Even more important is a bit, line with heating function of the present invention is flexible and convenient to use, range of application is wide, both the line with heating function that can be used as that wall warms up, used in floor heating, also can be used as the line with heating function in other heating products, also can be used as the ground hot line that airfield runway etc. needs snow removing defrost place in time to use, thus provide a kind of feasible, reliable material guarantee for flight safety; And all effectively can be applied among the multiple industries such as auto repair, road and rail maintenance and construction, also can be used widely in domestic life field.
Simple installation of the present invention, easy to use, the life-span is permanent, is suitable for promoting, and high frequency electric source can adapt to conventional power circuit, and operating efficiency is high, and practical value is large.
