Description
Technical field
The utility model relates to a kind of heater, particularly a kind of electromagnetic induction heater.
Background technology
In commercial production, especially in the industry that aluminium-plastic panel is produced, need heat equipment at present, traditional mode of heating generally has two kinds, and a kind of is to utilize the heating of fuel thing, and another kind is to utilize the heating of fuel thing, and another kind is to utilize the electric energy heating.Along with industrial expansion and progress, utilize the electric energy heating more and more, and comparatively general with the resistance wire heating in this mode of electric heating.But the resistance wire heating, its firing rate is slow, and thermal loss is big, and the heat efficiency is low, and very easily damages.Rising at present a kind of mode of utilizing electromagnetic induction heating.
The electromagnetism heating is to utilize electromagnetic induction principle to convert electrical energy into the method for heat energy; The electromagnetism heating normally becomes alternating voltage into direct voltage by rectification circuit; Convert direct voltage into high frequency voltage through control circuit again; The electric current that changes at a high speed flows through coil can produce the magnetic field that changes at a high speed, when the magnetic line of force in the magnetic field through metal ware (material that magnetic conduction conducts electricity again) bottom metal body in the countless little eddy current of generation.Therefore electromagnetic induction heater itself does not generate heat, and has the advantage of long service life, quick heating.
Shortcomings such as it is little that but electromagnetic induction heater of the prior art exists the unit are heating power, and the efficiency of heating surface is low limit its scope of application.
The utility model content
The purpose of the utility model is in order to overcome the problems referred to above, a kind of electromagnetic induction heater to be provided.
For achieving the above object; The method that the utility model adopts is: a kind of electromagnetic induction heater; Comprise electromagnetic induction coil, electromagnetic induction controller, described electromagnetic induction controller links to each other with electromagnetic induction coil through lead, and described electromagnetic induction coil is with the heated object around; Described electromagnetic induction coil is the composite laminate electromagnetic induction coil; The coil of being processed by the coiling of individual layer plane is overlapped into sandwich structure, and connects through series connection between every layer of electromagnetic induction heating circle, and is gapped between described electromagnetic induction coil and heated object.
As a kind of improvement of the utility model, described electromagnetic induction coil is radially double-deck lamination.
As a kind of improvement of the utility model, described electromagnetic induction device also comprises overcoat and interior cover, and described overcoat and interior cover are processed by insulating material, and described electromagnetic induction coil places between overcoat and the interior cover.
The beneficial effect of the utility model is:
1, firing rate is fast, can reach the required temperature of production technology fast.
2, through adopting the multilayer lap wound, inductance value and heating power are multiplied than single layer coil, and heating power density further increases.
3, through with being provided with the gap between electromagnetic induction coil and the heated object; Described gap is through air insulated electromagnetic induction coil and heated object; The alternating electromagnetic field that produces can be in the gap internal consumption energy, further improved the heat efficiency of electromagnetic induction heater.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein each parts is: cover, 5 heated objects, 6 electromagnetic induction controllers in 1 overcoat, 2 electromagnetic induction coils, 3 gaps, 4.
Embodiment
Like the described a kind of electromagnetic induction heater of Fig. 1; Comprise electromagnetic induction coil 2, electromagnetic induction controller 6; Described electromagnetic induction controller 6 links to each other with electromagnetic induction coil 2 through lead, and described electromagnetic induction coil 2 is with heated object 5 around, and described electromagnetic induction coil 2 is the composite laminate electromagnetic induction coil; The coil of being processed by the coiling of individual layer plane is overlapped into sandwich structure; Preferred as the utility model, described electromagnetic induction coil 2 is radially double-deck lamination, and connects through series connection between every layer of electromagnetic induction heating circle.Between described electromagnetic induction coil 2 and heated object 5 gapped 3.
Described electromagnetic induction device also comprises overcoat 1 and interior cover 4, and described overcoat 1 and interior cover 4 are processed by insulating material, and described electromagnetic induction coil 2 places between overcoat 1 and the interior cover 4.
The electromagnetic induction heater firing rate of the utility model is fast, can reach the required temperature of production technology fast.Through adopting the multilayer lap wound, inductance value and heating power are multiplied than single layer coil, and heating power density further increases.Owing to be provided with the gap between electromagnetic induction coil and the heated object, described gap is through air insulated electromagnetic induction coil and heated object, the alternating electromagnetic field of generation can be in the gap internal consumption energy, further improved the heat efficiency of electromagnetic induction heater.
The above; It only is the preferred embodiment of the utility model; Be not to be the utility model to be done the restriction of any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that the technical spirit of the utility model is done.
