Description
Technical field
The utility model belongs to firing equipment field, specifically, relates to a kind of novel electromagnetic heater, more particularly, relates to a kind of electromagnetism and loses the electromagnetic heater little, energy conversion efficiency is high.
Background technology
Heating refers to that thermal source passes to heat energy the process that makes its heating compared with cold object, according to the acquisition of heat energy, can be divided into directly and two classes indirectly.Direct heat source heating is that heat energy is directly added on to material, as flue gas heating, current flow heats and solar radiant energy heating etc.Thermal source heating is thermophore in the middle of the heat energy of above-mentioned direct heat source is added on to indirectly, then by middle thermophore, heat energy is passed to material again, as Steam Heating, hot water heating, mineral oil heating etc.
Traditional heating is in combustion chamber internal heat generation burning energy supply by coal, natural gas or fuel oil etc., or by electric energy energy transform into heat energy, but by easy contaminated environment of fuel such as coal combustion, natural gas or fuel oils, and process is wayward, energy dissipation is high, and especially the transportation of fuel can increase production cost; Heating for electric energy, Electromagnetic Heating commonly now, 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 at container bottom metal, partly produces the electric current (being eddy current) of alternation, eddy current makes the iron atom of container bottom do high speed random motion, and atom collides with each other, rubs and produces heat energy.Thereby play the effect of heating objects.Because be iron ware self-heating, heat conversion is high.Current electromagnetic oven, electromagnetic stove is all the electromagnetic heating technique adopting.Due to these advantages of Electromagnetic Heating, so the application of Electromagnetic Heating is more and more general.But, the radiation problem of electromagnetic oven more and more causes people's attention, especially in factory, operate the workman of large-scale electromagnetic heating apparatus, health hazard is maximum, the radiant power of electromagnetic heater depends primarily on the leakage value of this installation electromagnetical ripple, leak larger just larger to user's injury, because this injury is that we are invisible to the naked eye, therefore Electromagnetic Heating is also referred to as " stealthy killer ", and long-term or long-time use has larger negative effect to people healthy.
China Patent No.: 201010610836.5, open day 2011-05-11 discloses the patent document that a name is called electromagnetic heating oil boiler, it comprises conduction oil body of heater, conduction oil body of heater has oil inlet pipe, flowline, steam vent, drain oil, conduction oil body of heater below is equipped with a plurality of induction heating drums, and induction heating drum is connected with induction heater; Induction heater is fixed by induction heater storage bracket, and flowline place is provided with temperature protector, and temperature protector is connected with electric control box; Because conduction oil body of heater below is equipped with a plurality of induction heating drums, realize zero discharge, and by temperature protector can make converter life longer, maintain more conveniently, save human resources, and realize intelligent trouble judgement.This patent is drawn and is realized heating function by electromagnetism exactly, but has serious magnetic leakage problem, threatens user's health.
The reason that occurs above-mentioned situation is because no matter utilize on the market sandwich wound coil or externally-wound type coil carries out Electromagnetic Heating at present, in design, are all one-sided heater heating, all there is certain magnetic leakage, for example high frequency magnetic radiation is extremely strong, human body is had to significant damage, resource is caused to larger waste, especially for large-scale heater, the magnetic of losing is in the course of the work more, and workman's safety has also been caused to threat.
