Abstract
The utility model discloses an electromagnetic heating device comprising a housing, a metal heating unit and a coil, wherein the metal heating unit is arranged inside of the housing, and the coil is winded on an external surface of the housing. According the scheme provided by the utility model, magnetic field lines in a magnetic field generated by the coil firstly pass through an external surface of the metal heating unit, thus a temperature of the external surface of the metal heating unit is the highest, and the metal heating unit is completely arranged in heated liquid, thus the heat exchange efficiency between the metal heating unit and the headed liquid can achieve the maximization; in addition, the housing can obstruct heats generated therein, thereby avoiding excessive temperature of the coil, and ensuring safety of the heating.
Description
Technical field
The utility model relates to electromagnetism heating field, in particular, relates to and is used for the electromagnetic heater that heating and boiling water are used.
Background technology
Electromagnetism heating is as a kind of new Type of Heating system; It has broken traditional resistance wire heating system, adopts state-of-the-art magnetic field induction eddy current heating principle, and promptly electric current produces magnetic field through coil; When the magnetic line of force is through the magnetic conductive metal material in the magnetic field; Can make to produce countless little eddy current in the metallic object, make metal material heating at a high speed voluntarily itself, reach object temperature in the heating of metal material bodies.
Existing electromagnetic heater is that coil is arranged on the canister outside, and the electromagnetic induction that produces through coil heats to canister, and canister is again its inner liquid of heat transferred.
In research and practice process to prior art, the inventor of the utility model finds that there is following problem in prior art:
Because due to the kelvin effect, the magnetic flux density that coil produced successively decreases along with the increase of the degree of depth that gets into canister, thereby make in the process of electromagnetism heating; Canister is near the one side of coil, and promptly the temperature of the outer surface of canister is the highest, and the contacted one side of canister and heating liquid; The temperature of inner surface that is canister is minimum; So influenced the heat exchange of canister and heating liquid, reduced the speed of heating, and wasted heat energy; And, because the temperature of the outer surface of canister and induction coil is higher, so cause danger than being easier to.
Therefore, it is high how to make a kind of thermal conversion efficiency, and heats is good, and the better security electromagnetic heater, becomes the problem that needs most solution at present.
The utility model content
In view of this, the purpose of design of the utility model is, a kind of electromagnetic heater is provided, and to improve thermal conversion efficiency, makes heats better, improves the fail safe of heating.
The utility model embodiment is achieved in that
A kind of electromagnetic heater comprises housing, metallic heating body and coil;
Said metallic heating body is arranged on the inside of said housing, and said coil is wrapped in the outer surface of said housing.
Preferably, in above-mentioned electromagnetic heater, the two ends of said housing are respectively arranged with water inlet and delivery port.
Preferably, in above-mentioned electromagnetic heater, said housing is provided with delivery port.
Preferably, in above-mentioned electromagnetic heater, said housing is made of plastics.
Preferably, in above-mentioned electromagnetic heater, said housing is processed by fiberglass.
Preferably, in above-mentioned electromagnetic heater, said housing is columnar structured.
Preferably, in above-mentioned electromagnetic heater, said metallic heating body is a cylindrical structural.
Compared with prior art, the technical scheme that provides of the utility model embodiment has the following advantages and characteristics:
In the scheme that the utility model provides; The magnetic line of force in the magnetic field that coil produced can pass the outer surface of metallic heating body earlier; So the temperature of the outer surface of metallic heating body is the highest; And metallic heating body places heating liquid fully, thereby makes the heat exchanger effectiveness of metallic heating body and heating liquid reach maximization; In addition, housing can intercept the inner heat that produces, thereby has avoided the temperature of coil too high, therefore, has guaranteed the fail safe of heating.
Description of drawings
In order to be illustrated more clearly in the utility model or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

The utility model embodiment provides a kind of electromagnetic heater, comprises housing, metallic heating body and coil; Said metallic heating body is arranged on the inside of said housing, and said coil is wrapped in the outer surface of said housing.Above-mentioned electromagnetic heater has the thermal conversion efficiency height, and heats is good, and advantage such as fail safe is better.Because there is multiple mode in the concrete realization of above-mentioned electromagnetic heater, is elaborated through specific embodiment below:
See also shown in Figure 1ly, shown in Figure 1 is a kind of electromagnetic heater, comprises housing 1, metallic heating body 2 and coil 3, and wherein, said metallic heating body 2 is arranged on the inside of said housing 1, and said coil 3 is wrapped in the outer surface of said housing 1.In the present embodiment; The magnetic line of force in the magnetic field that coil 3 is produced can pass the outer surface of metallic heating body 2 earlier; So the temperature of the outer surface of metallic heating body 2 is the highest; And metallic heating body 2 places heating liquid fully, thereby makes the metallic heating body 2 and the heat exchanger effectiveness of heating liquid reach maximization; In addition, housing can intercept the inner heat that produces, thereby has avoided the temperature of coil too high, therefore, has guaranteed the fail safe of heating.
In the embodiment shown in fig. 1, housing 1 can be processed with nonmetallic materials such as plastics or fiberglass, and inside holds and need liquid heated, and housing 1 can be processed multiple shape, and is for example columnar structured.Metallic heating body 2 usefulness iron, stainless steel and other metal materials are processed different shape, cylindrical structural for example, and metallic heating body 2 is immersed in the liquid to be heated of housing 1.The coil 3 of housing 1 outside makes metallic heating body 2 heatings and conduction give liquid through alternating current.In addition, both can only set out the mouth of a river on the housing 1, also can water inlet and delivery port be set respectively at the two ends of housing 1.
Need to prove that embodiment shown in Figure 1 is the preferred embodiment that the utility model is introduced, those skilled in the art can design more embodiment on this basis fully, therefore do not give unnecessary details herein.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
