Description

Conversion electromagnetic induction heater

Technical field

The utility model conversion electromagnetic induction heater, belongs to electromagnetic heating technique field.

Background technology

Current, earth environment pollutes day by day serious, and society and the mankind are caused to increasing harm, and country has more and more banned coal heating now, utilizes solar energy, and the green energy resources such as electric energy are following trend.

But existing mode of heating, is the inside and outside Double-side heating by resistance wire coiling lopping, and the heat of its inner face (being close to barrel part) is transmitted on barrel, and the heat major part of outside is lost in air, causes direct losses, the waste of electric energy.Because heat scatters and disappears in a large number, ambient temperature raises, especially summer very large on production environment impact, more than what work on the spot temperature had exceeded 50 degree, some enterprise has to adopt air-conditioning to reduce temperature, this causes again the secondary waste of the energy.Electrothermal tube is owing to adopting resistance wire heating, and its heating-up temperature is up to 300 degree left and right, and thermo-lag is larger, is difficult for accurate temperature controlling, and resistance wire is easily because high temperature ageing blows.Conventional electric heating coil about half a year in service life, therefore, the workload of maintenance is relatively large.

And Electromagnetic Heating can not produce heat substantially because of coil itself, the life-span is long, without maintenance, without safeguarding replacement cost; Heating part adopts loop cable structure, and cable itself can not produce heat, and can bear more than 500 DEG C high temperature, and service life was up to 10 years.Do not need to safeguard, the later stage is subject to the welcome in market substantially without maintenance cost.Existing market also has Electromagnetic Heating mode, but this Electromagnetic Heating is by solenoid eddy-current heating, because limited length with a pipe, the area passing through is limited, generally can only improve 15 DEG C of left and right, need to repeat to enter electromagnetic heater, just can reach heating, the temperature of having a bath etc. and to need.

Utility model content

In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, the conversion electromagnetic induction heater of energy-conserving and environment-protective.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

Conversion electromagnetic induction heater, comprising: housing, and control section and heating part, described heating part is the construction of cable that iron metal tube is wound around solenoid outward, described heating part comprises outer ring and inner ring, and inner ring is sleeved in outer ring.

Described outer ring and inner ring are all wound in disc type by iron metal tube.

The beneficial effect that the utility model compared with the existing technology has is:

1, described heating part comprises outer ring and inner ring, and solenoid, simultaneously to inner ring and outer ring generation effect, heats the water in inner ring and outer ring simultaneously like this, has accelerated the speed of heating, and has saved the energy.

2, described outer ring and inner ring are all wound in disc type by iron metal tube, so just can be originally becoming a coil pipe by a pipe of solenoid, virtually increase by the duct length of solenoid eddy-current heating, increased heat time and heating surface (area) (HS.

3, the utility model only need to once heat just can reach have a bath heating condition, so in the time that needs are had a bath, open this equipment and just can have a bath, do not need shift to an earlier date plug-in accumulation of heat, so just can greatly save the energy.

Brief description of the drawings

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 is top view of the present utility model;

Fig. 2 is the top view of the utility model outer ring;

Fig. 3 is the front view of the utility model outer ring;

Fig. 4 is the top view of the utility model inner ring;

Fig. 5 is the front view of the utility model inner ring.

In figure, 1 is that outer ring, 2 is inner ring.

Detailed description of the invention

As Figure 1-5, conversion electromagnetic induction heater, comprising: housing, control section and eddy-current heating part, described heating part is the construction of cable that iron metal tube is wound around induction loop outward, and described heating part comprises outer ring 1 and inner ring 2, and inner ring 2 is sleeved in outer ring 1.

Described outer ring 1 and inner ring 2 are all wound in disc type by iron metal tube.

Between outer ring 1 and inner ring 2, be provided with electromagnetic induction coil.

The principle of Electromagnetic Heating be by electronic circuit board part produce alternating magnetic field, when with contain container made of iron place above time, container table mask cuts the alternation magnetic line of force and produces the electric current (being eddy current) of alternation in container bottom metal part, eddy current makes the iron atom high speed random motion of container bottom, and atom collides with each other, rubs and produces heat energy.Thereby play the effect of heating objects.Because be iron ware self-heating, all heat conversions are high especially, can reach 95%.

Known by Electromagnetic Heating principle, the height of the efficiency of heating surface has much relations with the pipeline length by solenoid, the utility model, by changing the layout of existing pipeline in calandria, has increased duct length and the area responded to by solenoid, so the technique effect reaching is good especially.

The utility model coordinates numerical control system and circuit protection system, can ensure equipment long-term safety reliability service, then it is energy-conservation to coordinate inductor and controller to accomplish, intelligence, and water power definitely separates, and starts the shut-in time as set.
