Abstract
The utility model discloses an electromagnetic induction heating device of a pipeline, which comprises a pipe body and a coil. The pipe body of the pipeline is made of metal materials. The outside of the pipe body is coated with an insulating shell. The coil is wound on the outer surface of the insulating shell. The interior of the insulating shell is provided with a groove and a soft magnet is embedded in the groove. Due to the adoption of the soft magnet, the consumption of enameled wires for the coil is greatly reduced, while the problem of low-power resonance is solved at the same time. Meanwhile, the pipeline with the electromagnetic induction heating device has the advantages of simple structure, low price and good insulation property, and high safety.
Description
Technical field
The utility model relates to the electromagnetic induction heating technology field, refers in particular to a kind of pipeline electromagnetic induction heater.
Background technology
Electromagnetic induction heating is to be heated that the steel body is sensed magnetic energy and a kind of mode of heating of generating heat through converting electric energy into magnetic energy, making, that is: electric energy is converted into magnetic energy, is converted into heat energy again.It has fundamentally solved electric heating piece, the electric heating coil constant resistance formula problem through the inefficiency of heat exchange pattern heating this mode, and electric energy is up to more than 40%-80%.Existing pipeline electromagnetic induction heater can't really be accomplished electricity separation, still have potential safety hazard in the use, and energy transfer efficiency is lower.Chinese patent publication number CN201467501; Open day on May 12nd, 2010; Name is called in the utility model patent of " flexible duct electromagnetic induction heater " and discloses a kind of flexible duct electromagnetic induction heater; Be made up of tape coil, multi-core socket, multi-pin connector and power line, an end of tape coil is connected with multi-core socket, and the other end is connected with multi-pin connector; Multi-core socket is connected with power line, and power line is connected with power supply; Tape coil is wrapped on the pipeline that needs heating.That this heater has is simple and easy, light, cost is low, be easy to dismounting, advantage such as removable, but this heater is still used existing pipeline electromagnetic heating technique, and the efficiency of heating surface is not high.
The utility model content
The purpose of the utility model is to overcome prior art middle tube body electromagnetic induction heater complex structure, cost height and the lower shortcoming of the efficiency of heating surface, provides a kind of simple in structure, the pipeline electromagnetic induction heater that the efficiency of heating surface is higher.
The purpose of the utility model is to be achieved through following technical proposals:
A kind of pipeline electromagnetic induction heater comprises body and coil, and body is a metallic conduit, and body is wrapped with insulation crust, and coil winding is on the insulation crust outer surface; Be provided with groove in the insulation crust, groove is embedded with soft magnetic bodies.Different with the body of traditional electromagnetic induction heating; Added soft magnetic bodies, the enamelled wire that coil needs reduces significantly, and whole body volume is diminished significantly; Reduced cost; Add the Q value ratio of equivalent loss resistance (induction reactance with) of the unit's of increasing substantially assembly after the soft magnetic bodies simultaneously, thereby solved the problem of low power resonant safely and reliably, make the heater can stable operation under the small-power state.Body is wrapped with insulation crust simultaneously, has avoided human body and the direct of electromagnetic induction heater to contact, and has improved fail safe.
As a kind of preferred version, groove has several, and groove is arranged on the axial of insulation crust.
As a kind of preferred version, axial groove quantity is two, and two grooves are symmetrical set with respect to the insulation crust central shaft.Two grooves are embedded with two soft magnetic bodies respectively, perfectly reached the effect that improves the Q value of unit assembly, and quantity are that two costs are lower.
As a kind of preferred version, body is the stainless steel aqueduct.
As a kind of preferred version, the inner surface of body is provided with antirust coat.Prevent the body reduction efficiency of heating surface of getting rusty.
The beneficial effect of the utility model is that the enamelled wire that coil is needed through the design that adds soft magnetic bodies reduces significantly, has solved the problem of low power resonant simultaneously.And this pipe structure is simple, and is cheap, and good insulating is safe.

Fig. 2 is a kind of structural representation that removes coil sections of the utility model.
Wherein: 1, coil, 2, body, 3, soft magnetic bodies, 4, insulation crust, 5, groove.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Embodiment: a kind of pipeline electromagnetic induction heater of the utility model, its blast structural representation is as shown in Figure 1, comprising: coil 1, body 2, soft magnetic bodies 3 and insulation crust 4.A kind of structure of heater is as shown in Figure 2, and coil 1 is wound on the outer surface of insulation crust 4, insulation crust 4 parcel bodys 2, and an end of body 2 connects water filling port, and the other end connects delivery port.Be provided with 5, two grooves 5 of two axial grooves in the insulation crust 4 and be symmetrical set in insulation crust 4 central shafts, groove 5 is embedded with soft magnetic bodies 3.Body 2 adopts the A3 iron material, and inner surface is provided with antirust coat.After water or other liquid get into body 2 by water filling port; Pass through electromagnetic induction principle; Be converted into magnetic energy by electric energy, magnetic energy is converted into heat energy again makes body 2 heating heating flow through water or other liquid of body 2, and water or other liquid flow out pipeline through the heating back through delivery port.Owing to added two soft magnetic bodies 3; Coil 1 needed enamelled wire is reduced significantly, and improved the Q value of unit assembly, solved the problem of low power resonant safely and reliably; This utility model can be at heating frequency 1500-40000HZ, trouble free service in the scope of power 300-1500W.
