Description
Technical field
The utility model relates to electromagnetic induction heater technical field, relates in particular to the induction of a kind of cumulative and without the electromagnetic induction energy-collecting heating apparatus of forcing cooling applicable micro metal pipe and the small-sized profiled piece of metal to heat among a small circle loading coil.
Background technology
Based on Faradic electricity magnetic induction principle, electromagnetic induction heating technology is to use the method that improves ac frequency, the alternating current that order changes at a high speed flows through coil and can produce the magnetic line of force of alternation, magnetic line of force through heating object forms loop, in its cross section, produce induced current (being eddy current) and form thermal effect, heated workpiece is generated heat rapidly, reach a kind of technology of the object of other material of heating of metal itself or indirect and Metal Contact, and be widely used in the Field of Heat-treatment of metal, the indirect field of the heating with magnetic conductive metal material or non-magnetic non-conducting material and civilian kitchen range, water heater and companion's heat etc. heat field widely.
The related significant components of electromagnetic induction heating technology is magnet exciting coil, and magnet exciting coil can adopt copper, the silver or golden of electric conductivity excellence, but due to silver, golden bi-material is expensive, so generally adopt copper cash.The most important index of magnet exciting coil is inductance and coil Q(quality factor q) value, in the time that magnet exciting coil and sensed heating object exist as the load of Circuits System, be an important heat efficiency index together with the inductance value of load, too low inductance value is regarded as short circuit (being equivalent to resistance infinitely small) in electromagnetic circuit.In medium-high frequency induction heating field, what also adopt is the mode of low inductance coil, improve current oscillation frequency and motor current and add that Forced water cooling system carries out work (if there is no cooling system but generally all need to adopt, IGBT(Insulated Gate Bipolar Transistor, insulated gate bipolar transistor, be power tube) can explode at any time, usually said aircraft bombing in industry that Here it is, this comprises domestic electromagnetic stove and molding machine heating field, once inductance value is too low, IGBT high temperature to explode the probability falling all very high).And while adopting the copper cash multiturn coil of high inductance, easily coiling goes out required high inductance, electric current is corresponding simultaneously can reduce, the copper cash that coil uses like this can adopt thinner copper cash and without the cooling system of forced water, Here it is domestic electromagnetic stove, molding machine heating field and large-scale workpiece heating, the technical method of accompanying hot field to adopt.Here there is a technology blind spot, adopt water-cooled copper can be applicable to the heating of narrow workpiece as the way of magnet exciting coil, but need water-cooled and air cooling equipment outside supplements, cause that machine weight is heavy, volume is large, be not easy to carry; And the way of the real core copper cash magnet exciting coil of employing high inductance, machine volume and weight are all well suited for portable, if but the pipe of heated workpiece volume too small (such as diameter is 20～63mm(millimeter), specify the length of heating region to be no more than 30mm) simultaneously, limited space, is difficult to the inductance value (number of turn deficiency) of the regulation that coiling goes out, due to narrow space, also be difficult to the thick copper lines of selecting end face sectional area larger, therefore be difficult to be applicable to the heating of small workpiece narrow range.
As the China Patent No. medium-high frequency induction heating multilayer sealing fastening pipe that is ZL201020237693.3, China Patent No. is the medium-high frequency induction heating multi-sealing plastic pipe fitting of ZL201020237670.2, China Patent No. is the pre-socket joint induction heating welding plastic pipe of ZL201120138231.0, China Patent No. is the pre-socket joint induction heating welding plastic fastening type pipe fitting of ZL201120138204.3, China Patent No. is the medium-high frequency induction heating plastic pipe of ZL201020237685.9, China Patent No. is a kind of fastening type pipe fitting of ZL201020275351.0, China Patent No. is the multiple seal hot melting fastening type pipe fitting of ZL201020188986.7, above-mentioned all fitting structures, in the time adopting medium-high frequency electromagnetic induction heating technology to the plastics of METAL HEATING PROCESS indirect steel-plastics composite pipe ectonexine plastics and pipe fitting, all there is narrow and small problem (the especially corresponding pipe fitting of pipeline of DN16～63mm diameter of actual needs heat affected zone of pipe fitting, according to national standard and town and country construction industry standard, effective heated length of its pipe fitting is only generally 20～36mm, at the desired basic inductance value of the general electromagnetic induction heater circuit of narrow space coiling (60～300uH(microhenry of normally working) like this, as civilian electromagnetic oven uses 90～110uH) inductance coil) possibility is minimum, so General Requirements gets final product so that electromagnetic induction controller is started working in the coil scope of 2～10 circles, even but 10 circle coils, its inductance value is also difficult to exceed 10uH, if at this coil inductance weight range, the magnet exciting coil of crossing low inductance can be regarded as short circuit in circuit, so the circuit design of electromagnetic induction heater is very complicated, make a general survey of whole field, there is no at present technical staff and can in the situation that not considering pressure cooling system, design load inductance amount lower than circuit that can smooth and easy work in 15uH situation.And in fact this operative orientation be also have circumscribed: the technology of IGBT not yet reaches resistant to elevated temperatures stage, too low load inductance is the arch-criminal of IGBT heating, said aircraft bombing refers to that IGBT explodes in the industry, is in-problem certainly so reduce by force the mode of coil inductance.
And in the research that in fact domestic patent of applying at present and technical staff are engaged in, aspect the research of Portable electromagnetic induction heating machine, the application study that few people heat for small space or miniature workpiece.Some patented technologies of applying for mainly for be the circuit design of electromagnetic induction controller and the winding structure about coil, but at least all do not take into full account about these technology of structure of coil the technical merit that electromagnetic controller is current, and in fact have a supposed premise: the inductance value that is exactly magnet exciting coil is can be successful according to the job requirement coiling of electromagnetic controller.Caused the design blank that relates to the portable electric magnetic controller that workpiece heats among a small circle so true.
In fact, also there is in the industry numerous technical staff to start to abandon the improvement research for circuit, then again load is improved and design, prerequisite is no longer to consider the requirement of induction power supply for load inductance and Q value, then the problem how research overall load matches.Current existing technology comprises: as the design principle of coil disc of electric stove, arrangement magnetic stripe around magnet exciting coil, thereby a small amount of winding inductance quantity that increases reduces coil turn, this technology cannot tackle the problem at its root, coil adopts wire diameter less, and the coil heating that self-resistance causes is difficult to solve.If add pressure cooling system, cannot solve again portable problem.Another kind of design principle is the mode (this technology is applied for a patent by the utility model people) that adopts medium/high frequency transformer to mate with medium-high frequency power supply, this mode has very strong applicability, but there is the problem that energy conversion efficiency is not high, in like manner also have the problem that medium/high frequency transformer temperature rise is larger.
