Of the present inventionly focus on by air cooling system of the present invention, make wind-power source (the blower fan E in Fig. 1) carry out more effectively, stably dispelling the heat to controlled target temperature A.
Fig. 2 a and Fig. 2 b shows the block diagram of the Electromagnetic Heating temperature-controlling system of a subregion of Electromagnetic Heating barrel (a kind of concrete form of controlled target temperature A).Each subregion technological temperature of barrel 4 requires different, but the structure of each subregion is identical.The screw acting current downflow of material in barrel 4, is heated by solenoid 2 in flow process.In order to reduce the outer loose of heat, between solenoid 2 and barrel 4, swathe the heat insulation layer 3 that insulating heat insulating material is formed.Fig. 3 a to 3c is the structural representation of an embodiment of its air cooling system, illustrates the structure of the radiating part that heat is derived by Electromagnetic Heating temperature-controlling system.The air cooling system of a kind of Electromagnetic Heating temperature-controlling system of the present invention, comprises radiating part and wind-power source (such as blower fan).The outer wall that radiating part is close to barrel 4 is installed.As an embodiment, radiating part can be distributed in barrel 4 zone temperature sensor B both sides, and can there be 1 or two panels or multi-disc radiating part in every side.Described radiating part comprise heat conduction bar 7 (for heat radiator 5 heat conduction), heat radiator 5 (for by heat conduction to the air-flow passed through in air channel 6) and air channel 6 (air feed flows through).The xsect of described heat radiator 5 can be linear, bent, circular arc or waveform, or the combination of aforementioned at least two kinds of shapes, and described heat radiator 5 also can be sandwich construction or comb shaped structure.Described heat conduction bar 7 is at least two its length directions or approximately perpendicular list structures vertical with solenoid 2 winding direction of Electromagnetic Heating temperature-controlling system, the outer wall close contact of the controlled target temperature A (such as barrel) of described heat conduction bar and Electromagnetic Heating temperature-controlling system; Can be connected with each other or not be connected between multiple described heat conduction bar 7; Described heat conduction bar 7 can parallel to each other or less parallel, as shown in Figure 3 a, can certainly be not parallel, as shown in Fig. 4 a, Fig. 5 a, can prevent electromagnetic eddy from producing in heat conduction bar 7.Described heat radiator 5 is connected with described heat conduction bar 7, also bending structure 51 can be had in this junction, described bending structure 51 can be that all heat conduction bars 7 same one end is along its length connected with heat radiator 5 (situation as Fig. 3 a to 3c), also can be that certain heat conduction bar 7 is connected (not shown) at the side of its Width with heat radiator 5.Heat radiator 5 on radiating part and heat conduction bar 7 can be one, or multiple, and the quantity of heat radiator 5 and heat conduction bar 7, arrangement mode, position, size etc. can be all do not rely on ground, change mutually, can certainly be identical.Described heat radiator 5 has in the part be not connected with heat conduction bar 7 and sticks up fin structure 52 (as shown in Figure 3 c).Describedly stick up bending structure 51 that fin structure 52 refers to due to heat radiator 5 and make heat radiator 5 and heat conduction bar 7 not on the curved surface of same plane or same radius-of-curvature, thus the space structure that the curved surface of the plane or same radius-of-curvature that make the free end of heat radiator 5 leave heat conduction bar 7 is formed.The form of described heat radiator has multiple, such as single heat conduction bar is connected with single heat radiator, or multiple parallel heat conduction bar is connected with at least one heat radiator, or the two ends of same heat conduction bar all connect same form or multi-form heat radiator, and (heat radiator of so-called same form refers to it is strip or sheet heat radiator equally; So-called multi-form heat radiator refers to, the heat radiator at heat conduction bar two ends is respectively strip and sheet) etc.The space formed between the outer wall of fin structure 52 and described controlled target temperature A and/or the other parts of radiating part of sticking up of described heat radiator 5 forms described air channel 6.The concrete form in air channel 6 has multiple, as embodiment, air channel can be the formation air channel, space between the outer wall sticking up fin structure 52 and described controlled target temperature A of described heat radiator, also can be described heat radiator stick up fin structure 52 and other heat radiator stick up fin structure (such as at barrel axially, the heat radiator that same heat conduction bar connects at the two ends of its length direction stick up fin structure respectively and sticking up between fin structure of adjacent two heat radiator form air channel, or the sticking up between fin structure of the heat radiator of fin structure and other heat conduction bar of sticking up of heat radiator that heat conduction bar connects forms air channel etc.) between the air channel that formed along the space that barrel sidewall longitudinally arranges formation in opposite directions, also can be described heat radiator stick up the air channel that the space between one end that fin structure 52 and heat conduction bar 7 do not tilt forms, also can be that sticking up between fin structure periphery and described insulation heat proof material shell of described heat radiator forms air channel.If same heat conduction bar 7 connects multiple heat radiator 5 with the vertical section of different barrel radical lengths, namely these heat radiator 5 are comb shape or sandwich construction, can be so that multiple heat radiator has a bending structure 51, and the part that each heat radiator 5 is not connected with bending structure 51 is one sticks up fin structure 52, therefore the multiple heat radiator be connected with same heat conduction bar 7 or bending structure 51 to stick up between fin structure 52 or these stick up the free end of fin structure 52 and other heat conduction bar 7 or other heat sink strip sticks up between fin structure 52 (single or multiple) and the outside wall surface of barrel or insulate between heat proof material shell and also can form air channel.Certainly can also be other form, such as adjacent or non-conterminous multiple heat radiator 5 stick up fin structure 52 height difference (as stick up in Fig. 3 b fin structure there is differing heights H1 and H2 when, multiple heat radiator can form sandwich construction), as long as the space of air circulate wherein can be made, whether no matter close, are all the implications in the air channel 6 in the present invention.Air channel 6 is preferably vertical with the direction of heat conduction bar 7, and its direction can be also any angle with heat conduction bar 7 direction certainly.The air outlet in described wind-power source (such as blower fan E) is connected with the air inlet in described air channel 6, air-flow is passed from described air channel 6, thus takes away heat.
Described heat radiator 5 and/or heat conduction bar 7 can be all preferably that such as aluminium, copper etc. are made by plasticity is good, temperature conductivity is high, nonmagnetic material.Usual use aluminium sheet or copper coin, make processing simple.Also can being exposed in air by sticking up fin structure, adopting natural heat dissipation.
For the ease of processing, described heat radiator and heat conduction bar preferably, can be integrative-structures, and such as described heat radiator is arranged to bending structure and sticks up fin structure formed by a part for described heat conduction bar; Can certainly be combined by least two parts, be connected by welding or riveting method between each ingredient.
Described heat conduction bar 7 can be the lattice structure be made up of remaining part after sheet material removing multiple parallel groove, as shown in Fig. 3 a, Fig. 4 a, Fig. 5 a, is convenient to processing and installs, and owing to being interconnected between each heat conduction bar 7, good heat conduction effect.In this case, if multiple heat conduction bar 7 is connected to each other by join domain at its free end, the distance b at the edge of the groove ends then near the width b of described join domain and the free end of described heat conduction bar 7 and the free end of described sheet material (is a) 0 to 5mm see Fig. 3, in this numerical range, the width of join domain be 0 situation represent multiple heat conduction bar 7 and do not connect at its free end.
The thickness δ of described heat conduction bar 7, as shown in Fig. 3 b, 4b, 5b, is preferably 2 to 4mm, has both been conducive to heat transfer, heat conduction, is conducive to again processing and saves material.And the width of heat conduction bar 7 is preferably 3 to 5mm, the spacing between multiple heat conduction bar 7 is preferably 1 to 4mm, and width and the spacing of described heat conduction bar 7 can be distinguished identical or not identical.
Described heat conduction bar 7 can have connecting portion in the junction with described heat radiator 5, and the width a of described connecting portion is as shown in Fig. 3 a, 4a, 5a.In this case, described connecting portion can be rectangle as shown in Figure 3 a, also can be trapezoidal as shown in Fig. 4 a, Fig. 5 a.The described fin structure 52 that sticks up outwards stretches the vertical section of a section by the radial direction of arbitrary xsect of the controlled target temperature along described central rotating body and forms along the extension that the outer wall of the controlled target temperature of described central rotating body is extending longitudinally, the extension of sticking up fin structure 52 described in the vertical section with different radical length is arranged in opposite directions, vertical section is in opposite directions spaced from each other a distance, and forms described air channel 6.Described heat radiator 5 can also be identical, parallel with described heat conduction bar 7 length direction or approximately parallel list structure.Now the width a of described connecting portion is preferably 10 to 50mm.The width a of described connecting portion refers to that heat conduction bar 7 is in the one end be connected with heat radiator 5 and the distance of heat radiator 5 between one end that heat conduction bar 7 is connected, as shown in Fig. 3 a, 3b, 4a, 4b, 5a, 5b, heat conduction bar 7 is connected with described heat radiator 5 by described connecting portion along its length, then the width a of connecting portion refers to that heat conduction bar 7 is towards the distance between the end and described heat radiator 5 in heat radiator 5 direction.
The described thickness sticking up fin structure 52 preferably, can be less than the thickness δ of described heat conduction bar 7, increases width, adds cooling surface area, be beneficial to heat radiation.
The described fin structure 52 that sticks up can be schistose texture relative to heat conduction bar 7 surface deflections certain angle or circular arc body structure, is convenient to the surface area increasing heat radiator, is beneficial to ventilation and heat.Can understand like this and described stick up fin structure distortion certain angle: if what be wound around with solenoid is axially the z-axis of cylindrical coordinate, the polar angle θ direction of the cross section polar coordinate system that the circumference be wound around with solenoid is cylindrical coordinate, then the radiation direction of this cross section polar coordinate system central vertical in z-axis direction is r direction, footpath, pole, under this cylindrical coordinate, if the controlled target temperature of Electromagnetic Heating temperature-controlling system is barrel 4, due to barrel 4 normally right cylinder, and heat conduction bar 7 is close to barrel outer wall, therefore heat conduction bar 7 normal to a surface direction is r direction of principal axis and the r durection component of the surperficial every bit of heat conduction bar 7 is identical, as long as the surface that the surface direction of so sticking up fin structure 52 is not parallel to heat conduction bar 7 (describedly parallelly both can comprise the parallel of plane, also the parallel of curved surface can be comprised), then can be called and stick up fin structure 52 relative to heat conduction bar 7 surface deflections certain angle.A kind of situation sticks up that fin structure 52 each point r value is along the z-axis direction not identical but r value that is different θ direction on same z-axis direction is identical, and so claiming to stick up fin structure 52 is tilt and distortion certain angle along the z-axis direction; Another kind of situation sticks up that fin structure 52 each point r value is along the z-axis direction all identical but r value that is different θ direction on same z-axis direction is not identical, and so title sticks up fin structure 52 is distortion certain angles along the inclination of θ direction of principal axis.These the two kinds surface deflections certain angles tilting all to belong to relative to heat conduction bar 7, because the latter is less to the stop of ventilating air in air channel 6, because the result of ventilating heat dissipation of this latter is better; Certainly stick up fin structure 52 each point r value along the z-axis direction all not identical with the r value of each point in different θ direction on same z-axis direction, also belong to above-mentioned and stick up the surface deflections certain angle of fin structure 52 relative to heat conduction bar 7.

As an embodiment, as shown in Fig. 3 a to 3c, the fin structure 52 that sticks up of the radiating part of temperature sensor B both sides is positioned among the air channel 6 that the outer wall of barrel 4 and insulation heat proof material shell 1 form, when the wind that blower fan E blows to be blown into from air intake vent 11 and to blow out from air outlet 12, in air channel 6 heat radiator 5 stick up the barrier effect of fin structure 52 under form numerous vortices, fully take the heat spread out of by barrel 4 out of.Described heat insulation layer 3 can be made up of insulating heat insulating material.The annulus that air channel 6 is formed by the outer wall of insulating material housing 1 and barrel 4 is formed, and the both sides of annulus preferably adopt filled thermal insulation materials.The fin structure 52 that sticks up of heat radiator 5 is distributed among air channel 6.
The Main Function of insulation material is insulation, also has an effect to be as the filling material of both sides, air channel, can avoid side leakage wind; Also can as the filling material between insulating material housing 1 and solenoid 2, what be used for levelling heat radiator 5 sticks up fin structure 52, to make outward appearance more attractive in appearance.
Installation site according to blower fan E drives air port into, outputs air port, then blower fan is connected to air inlet on the opposite of air inlet.The opening of air inlet 11 and air outlet 12 is not limited to upper and lower opening, can be left and right or other direction openings, aperture position is determined depending on site specific, but in order to ensure the even of barrel 4 heat dissipation capacity, angle between the position of air inlet 11 and air outlet 12 preferably keeps 180 degree of directions, certainly, slightly error is also little on heat radiation impact.
The heat of friction that barrel 4 produces conducts to heat conduction bar 7 by barrel 4, then conducts to heat radiator 5, then takes heat out of by forced draft wind-power sources such as () such as blower fans, reaches the object of equilibrium temperature.
As a kind of embodiment, two panels or four parallel radiating parts can be installed as a subregion along barrel 4, if two panels radiating part, two panels radiating part is distributed in the both sides of temperature sensor (being arranged in a through hole of barrel sidewall) along barrel circumference when mounted; If four radiating parts, two panels radiating part is distributed in each two panels in temperature sensor both sides along barrel circumference when mounted, and every side barrel is along each a slice radiating part of barrel axial distribution.More multi-disc radiating part or only installation a slice radiating part can certainly be installed outside barrel 4, as a subregion in a similar manner.
