Abstract
The utility model relates to a low-temperature heating device which has a metal conductor wound with a metal coil. Two leading ends of the coil are connected with a fundamental frequency power supply. The utility model combines the coil and the conductor or a magnetizer into a whole. Connection of the coil and the fundamental frequency power supply can produce an alternating electromagnetic field. Conversion between electric energy and thermal energy is realized by vortex formed during alternation of the electromagnetic field. Therefore, little energy consumption is produced during the energy conversion thus using cost can be reduced accordingly.
Description
The utility model relates to a kind of low temperature electric heater unit, especially closes the heating of in being applied in cavity object or to the device of the heating of the open area in the confined space.
Electrically heated temperature is referred to as low-temperature heat in 50-400 ℃ of interval in the air.The heating main body of low temperature electric heater unit generally adopts resistance wire at present, because of resistance be a kind of hinder electric current by the time convert electric energy to the parts of heat energy, this parts simple in structure can be finished the electric heating task easily, so many household electrical appliance and industrial equipment are so long as all adopt this kind parts for the occasion of low-temperature heat.Yet, because resistance heating results from the collision of current-carrying charged particle with the fixedly particle in the conductor, and then the conversion between realization electric energy and the heat energy, therefore, some current-carrying charged particle does not bump with fixing particle in the transfer process of energy, even the particle that bumps also has certain loss in its conversion process of energy, so, the energy consumption of traditional resistive heating device is bigger, and use cost is higher relatively.
Task of the present utility model provides a kind of electromagnetic field of alternation that utilizes magnetic conductor is carried out the electrically heated device of low temperature, with the loss in the reduction conversion process of energy, and then reduces use cost.
For finishing above-mentioned task, device described in the utility model has a metallic conductor, is wound with wire coil on conductor, and two exits of its coil are connected with power frequency supply.When wire coil is connected with power frequency supply, its electric current by coil will alternately change along with the frequency of power supply, and then having produced the electromagnetic field of alternation, the electromagnetic field of this alternation is finished electric energy and heat energy conversion by the metallic conductor that is provided with in coil, makes the metallic conductor heating.
Described metallic conductor can be made of metal sheet, and its wire coil is wrapped in the subregion of the outer surface or the outer surface of this plate.
Described metallic conductor can be made into cylindrical or the prismatic or important actor shape of real core, and its wire coil is wrapped in the subregion of the outer surface or the outer surface of described cylindrical body.
Described metallic conductor can be made into cylindrical or the prismatic or important actor shape of hollow, and is wound with wire coil on described cylinder outer wall.
Described metallic conductor can be made into frame shape, and is wound with wire coil on each conductor that constitutes framework.
The metallic conductor outer setting that described periphery is wound with wire coil has the heat-insulation layer that is made of insulation material.
The exit of described wire coil also is provided with a modulator that is convenient to adjust its temperature.
The utility model adopts the structure of the outside winding around of metallic conductor, coil and conductor or magnetic conductor are become one, when coil and power frequency supply are connected, can produce the electromagnetic field of alternation, realize conversion between electric energy and the heat energy with electromagnetic field formed eddy current in the alternation process, so, in the transfer process of energy loss quite little, use cost also decreases; This kind device can be made geometry arbitrarily as required simultaneously, is applied in the multiple occasion that needs low-temperature heat, particularly can be applicable on polytype household electrical appliance, and as seen the field of its application is very extensive; In addition, the heating part of this device has heat-insulation layer and modulator as additional again, and its use cost also can reduce.
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing 1 is the surface structure schematic diagram of an embodiment of the utility model;
Accompanying drawing 2 is cross-sectional view of another embodiment of the utility model.
Referring to Fig. 1, it provides the surface structure of one type of low-temperature heating device.As can be seen from the figure, this device has a hollow and cuboid 1 that made by permeability magnetic material such as steel plate, outer surface at cuboid 1 securely is wound with preferably by copper wire coil of manufacturing 2 and the insulation framework 3 that is arranged on coil 2 peripheries, the number of turn of its coil 2 can be installed concrete purposes needs according to this and be determined, generally speaking, along with the increase of coil 2 numbers of turn, heated object is that the temperature of cuboid 1 also increases thereupon.Be insulation and the temperature adjusting performance of strengthening this device, at the also additional heat-insulation layer 4 that has one deck to constitute in the outside of described coil 2 by insulation material, and the modulator 5 that is arranged on coil 2 exits.Heat-insulation layer 4 can make concentration of energy need heat the position at it, and modulator 5 can be adjusted the size of electric current as required, and then adjusts the temperature of heated object.
Referring to Fig. 2, it provides the cross-section structure of the another kind of type of low-temperature heating device.The structure of this device is basic identical with the structure of the foregoing description, different is the cylindrical shell 1 that magnetic conductor is made by materials such as steel, radially be provided with coil 2 and insulation framework 3 at cylindrical shell 1, and heat-insulation layer 4, the exit of coil 2 also is provided with modulator 5, in addition, also is added with a loam cake 6 and shell 7 on the top of cylindrical shell 1, so, the operation principle of this embodiment is no longer elaborated.
The operation principle of this device is to use the coil 2 formed eddy current that join with the power frequency electricity to realize power conversion; so; no matter magnetic conductor is any shape, covers within the scope that the utility model is protected as long as the structure that adopts coil and magnetic conductor to form one is finished all letters of heating tasks.In addition, heater described in the utility model on can be applicable to household electrical appliance, also be suitable for being applied in as plastics, pitch, coating etc. are needed on the industrial equipment of low-temperature heat.
