The specific embodiment

Referring to figs. 1 through 4; radiation appliance 10 comprises by what be insulated that A font aluminium that coating protects or steel profile make and transports member 12 and midfeather 14; this midfeather 14 has defined rear volume and anterior volume; rear volume has formed the longitudinal duct 16 of square-section; and anterior volume has formed groove 18; this groove 18 roughly is configured as reverse U shape, and at the one side opening.One end of conduit 16 is fitted with gas-liquid inlet (the aeraulic mouth) 20 that is used to provide cooling fluid.

Aluminium section bar has experienced the hard anodizing of about 50 μ to be handled; so the coating for surface protection that forms can bear various mechanical shocks on the one hand; and give the higher resistance of this part on the other hand, and to the higher resistance of the short circuit current that may exist of this radiation appliance inboard to the leakage current in around the mechanism that radiation appliance is installed on it.The ground link of radiation appliance and the ground link of machine are isolated.

Midfeather 14 comprises variable cross-section hole 22, and these hole 22 interlaced arrangement are on each side of the mid-plane 24 of bearing structure, and these holes 22 provide a lot of openings between the front groove 18 of conduit 16 and member 12.Midfeather 14 is fitted with two blocks 26, and these two blocks are arranged on each side of mid-plane 24 and interior side-prominent to anterior volume 18.

Two sidewalls that define the anterior volume 18 of member comprise the longitudinal groove 28 of a circular cross-section on its outer surface respectively, and this groove 28 is corresponding with the boss 30 of formation in the anterior volume 18.

The anterior volume 18 of member 12 is occupied by radiation appliance, and this radiation appliance comprises the transmitter 32 that is positioned on the member mid-plane, and is positioned at transmitter 32 both sides, and on certain distance with respect to two sidepiece reflectors 34 of this mid-plane symmetry.

Transmitter 32 is for being filled with xenon or krypton gas or neon or other any lamp with gas of similar characteristics, the cylindrical tube 36 that this lamp is made by suprasil constitutes, at the inboard plasma generator post of launching in ultraviolet ray and/or visible light and/or infra-red range of having placed of this pipe.

The importance of this transmitter is that its pulse produces.The variation of generator power supply parameter realized side by side and in required ratio ground, and the UV wavelength mixed with infrared IR wavelength during in each flicker on the same radiating surface.By continuing of flicker, the first flicker UV can also be provided earlier on same radiating surface, provide the second flicker IR then, or vice versa; Or moreover, provide earlier by the first flicker UV that is mixed with a certain amount of IR than small scale, provide then by another flicker IR that is mixed with a certain amount of UV than small scale.Each axle head of cylindrical tube is fitted with ceramic connecting piece 38, and this connector is fitted with external electric joint 40, and electric connection 40 is connected on the electrode 42 that is inserted in this pipe.

Preferably, transmitter 32 also can be made of the lamp that is filled with mercury or its metal iodide derivative.

Each longitudinal end place at the anterior volume 18 that transports member 12 is furnished with locating flange dish 44, and as seen this ring flange, and comprises side rail 46 in Fig. 2 and Fig. 4, and this guide rail 46 slides on two sidepiece boss 30 to determine its position.Each ring flange has its opening towards the U of midfeather font sector notch 48, and the inner reflection surface 48a of ring flange 44, and this interior reflective surface makes the radiation of radiation source 36 towards radiating surface, to eliminate edge effect.This sector notch comprises visible shoulder 47 among Fig. 4 and is used to locate the wider portion of the fixture 49 of punching press.Preferably, this fixture 49 also can be replaced with the parts of being made by teflon or similar material, its thickness and diameter are enough for the groove of ' O ' shape ring of ceramic connecting piece 38, the outside geometric profile of this connector has identical design with parts 44, thereby, the symmetry with respect to axis 54 is provided.

As a kind of variant, preferably, externally in the plunger 72, fixture 44 can be replaced by the blind hole on the symmetry axis that is positioned at lamp.Outside and

internal piston

72 and 74 forms by the molded same section of insulating materials.Then, the ceramic connecting piece of lamp can be by ' O ' shape ring or by the insensitive and resistant to elevated temperatures elastomeric adhesives of UV is fixed in the blind hole of plunger 74.

With electrode afterbody and ceramic connecting piece between the identical height of line on, midfeather 14 comprises a big opening 50.Ring flange itself stamps out opening 41.

Each reflector 34 is made by shape, especially aluminium or steel, and this section bar comprises reflective recess front surface 52.As perpendicular to shown in the cross section in the plane of the axis of cylindrical tube 36 like that, the envelope of the same ellipse of reflecting surface 52 couplings of two reflectors 34, this oval focus will be positioned on the axis 54 of cylindrical tube.Each reflector 34 is fitted with bigger main fin 58 on its rear surface 56 1 sides, and is fitted with the cooling ribs 60 that forms less relief.Inter-access piece 62 help reflector in transporting member 12 the location and rest on the corresponding block 26 of midfeather 14.

Two adjacent edges 64 of two reflectors 34 have defined the cannelure 66 of the axis 54 that is parallel to pipe 36.Form a space between groove 66 and midfeather 14, this space laterally appears on the hole 22.Near gas-liquid inlet 20, the air velocity in the conduit 16 is higher than the speed at other place, opposite end that is electrically connected tap 78 places, goes to zero in the speed that is electrically connected tap 78 places.Thereby in order to obtain uniform distribution of gas along gas-liquid inlet 20, air pressure increases along with reducing of speed, and the cross section of running through in hole 22 reduces to locate bigger at pressure.The cross section of running through in these holes 22 is reduced to other higher 78 places, opposite end of pressure gradually, so that crossflow is even after midfeather 14.

Two ring flanges 44 have all been put into the end of sidepiece reflector 34, with the described reflector of longitudinal register in the groove 18 forwardly.

The cooling air is imported with the pressure that is higher than the load loss that is caused by the circulation of gas process gas circuit 17 at the rear portion of reflector 34.The existence at rib 58 and hook end edge 59 has increased the moment of inertia with respect to the air pressure thrust axis at reflector rear portion of reflector 34, to eliminate the distortion of the reflector of being made by extrudate 34.In addition, the reflector 34 that is used for long radiation appliance (long to 4 meters) (especially producing the industry that cardboard or weaving loom are weaved cotton cloth) strictly is held in straight line by rib 58, and reflector 34 rests on the block 26 of midfeather 14.Because relative force is each other for negative, two reflectors 34 are all keeping symmetry and motionless in good condition with respect to axis 24.

The rear portion of each reflector 34 is shaped according to a very effective heat exchanger.For this purpose, reflector assembly 34 is coated with nickel coating, and it can make heat emissivity coefficient with respect to exposed aluminium surface 11-fold increase.In addition, in the inswept reflector of cold air 34 back in the localities, radiating surface is increased by the riblet bar of locating to interlock at following 3 60, that is: on 15 ° the inclined-plane on reflector top, the rib 58, and in the centre of reflector 34 and the bottom.

Midfeather 14 is fixed the reflectivity longitudinal blade 68 of an aluminium in the middle by groove 15, this blade 68 is faced by two supports 15 ' maintenance and by groove 66 and pipe 36.

In addition, the every end that transports member 12 is equipped with outside plunger 72 and internal piston 74, they in Fig. 2 and Fig. 4 as seen.Outside plunger 72 closes ducts 16.It is fitted with four studs 76 that are inserted in the circular groove that transports member.Internal piston 74 is an arc, and therefore the flow direction with cooling fluid changes 90 °, and has guaranteed enough electric insulations by its structure, with electric connection point and the sealing of its service cable with lamp.Plunger 72,74 is made by plastic material, with by being engaged in the described section bar and with the form fit of this section bar, strengthen electric insulation simultaneously.

The end with respect to the gas-liquid inlet of member is fitted with the tap 78 of multiway electricity, and it is shown in Figure 5, is used to be less than or equal to the lamp supply voltage of 3000V magnitude.More than the value, that is, reach 10 at these, 000V or bigger, electric conductor pass ventilation sheath (ventilation sheath), and this sheath has been guaranteed the superinsulation to human body safety.

Gas-liquid inlet 20 is connected by the pipeline 99 in fan 96 downstreams, and this schematically shows in Fig. 3.Alternatively, in addition this device is fitted with the nozzle 98 that is positioned at fan exhaust mouth place, and this nozzle 98 has been realized the discharging to the water smoke that comprises the suspension fine liquid particles of gas-liquid inlet 20 and air conduit 16.According to a kind of distortion, nozzle 98 can directly be arranged in gas-liquid inlet 20 near.

The assembling as follows of this device:

The longitudinal end of reflector 34 is integrated with ring flange 44 by means of eight of hole 45 pins 53 that are placed in the hole 55 and pass two ring flanges 44, and hole 55 is arranged in the end return portion 59.The place, an end that is connected electrically in radiation appliance of transmitter 32, the power line of the opposite side of lamp passes through the hole 57 of reflector 34 and is turned back to being electrically connected side.The hole 57 of another reflector 34 is used to lay exposed ground link.

Thereby, two end flange dishes 44, two reflectors 34 and transmitter 32 formed one independently, the sub-assembly of electromechanical, this assembly can insert by sliding along the boss in the anterior volume 18 of member 12 30, and inter-access piece 62 slides on block 26 simultaneously.Therefore, from the viewpoint of mechanical, electrical, heat and gas-liquid, this sub-assembly is independent of and transports member 12 very much.At each sidepiece reflector 34 with transport relatively between the sidewall of member 12 and formed continuous space, this space is by at each reflector leading edge with transport the groove 80 between the respective wall edge of member 12 and manifest in the front side, and manifests at rear side by the hole 22 that gets out in the sidewall.In case being inserted and positioned on, this sub-assembly transports in the member 12, then keep reflector 34 and ring flange 44 just on a length, exposing on its rear surface for the pin 53 of one, this length makes them block the inner surface 73 of internal piston 74, and the plastic material of internal piston 74 has enough elasticity to absorb the expansion of reflector 34.

The exterior channels 28 that transports member can be inserted device 10 as the drawer in the machine parts that is fitted with complementary closed slide.The compactedness of this assembly, hardness and globality make this device in maintenance work or change in the process and can change fully as a part, rather than in the element of repairing or this device of local replacing one.

At work, the heat of this device and gas-liquid behavior are as follows:

Cooling fluid injects conduit by inlet 20.From comprising inlet 20 end towards the opposite end, the cross section in hole 22 is different, changes with the pressure of compensation along conduit 16, and makes fluid with substantially invariable velocity flow via hole 22.The part of fluid flows to the space that is exposed in the radiation by groove 66, in this space, fluid participate in the reflecting surface 52 of reflector and with the heat exchange of pipe 36.Another part of fluid following form between the rear surface 56 of the sidewall of member 12 and reflector 34 and flow by the circuitous path that groove 80 manifests, the mid-plane 24 of radiation space is roughly guided the fluid that flows out in this path.This part fluid carries out the heat exchange with reflector rear surface 56, and this point is very important because of the length of the distance 17 of being flowed through, and this distance helps to increase heat exchange surface simultaneously and slowing down fluid descends.Riblet bar 60 and nickel coating also help to increase this heat exchange.

In the end of transmitter 32, opening 50 and 41 can flow fluid and cooling can be taken place.

Reflection lobes 68 has been realized the reflection of radiation from groove 66.This blade has also completely cut off midfeather 14 and has contacted with any of infra-red radiation, and the latter can cause constituting the hot-spot of the section bar that transports member 12, and makes element produce inhomogeneous deformation.

The different thermal expansion of reflector 34 and member 12 causes the slip of ring flange with respect to boss 30, and inter-access piece 62 is with respect to the slip of block 26, and the displacement of radiation assembly end is absorbed by the elasticity of internal piston.

The mechanical thrust that block 26 renitency fluids produce along the rear surface of reflector 34, and guaranteed thus between the neighboring edge 64 of the existence of groove 66 of constant width and two reflectors 34 evenly, no matter and gas-liquid thrust how.

Up to now, word " cooling " is in general sense.In fact, if radiation transmitter comprise to thermal shock (such as, for example when lighting lamp) or quartz packaged in the plasma (high thermograde mainly influences by mercury, gallium and/or lead, iron and/or cobalt and/or has the plasma that other metal iodide of similar characteristics forms) of high-temperature gradient sensitivity, so, the cooling of transmitter will be restricted to indoor air or for example use of the neutral gas of nitrogen, and this neutral gas is used for the product that will be passivated.

On the contrary, if radiation transmitter comprises the plasma to thermal shock half sensitivity, as by xenon, krypton or the plasma that forms by other relevant ions oxidizing gases with identical characteristics, so, because transmitter has cold plasma or is fitted with the sheath of softening cooling water owing to plasma emitters as previously described, except that the environment air, some gases can be used for replacing oxidation resistant in essence neutral gas, promptly because of water, the preferably sprinkling of demineralized water and have the air of relative humidity ratio, this air promotes the reduction of temperature by utilizing evaporation latent heat, or be in and be lower than 20 ℃ or be lower than air under 0 ℃ the temperature, or even the demineralized water under the room temperature, wherein demineralized water submergence radiating element.Demineralized water provides the conducting end that can make lamp to contact with cooling water and without any the resistivity of electric fault risk.

By groove 66 spray water, at the inwall of the quartz ampoule 36 that the plasma with about 5000 ° of K to 7000 ° of K contacts with directly and between the outer wall that contacts of 20 ℃ water provide high thermograde, and can not change plasma or its spectrum or the energy size that in the wave-length coverage of being considered, is discharged.Therefore, should utilize the latent heat of the water that suspends in the cooling air under preset temperature, especially with the contacted surrounding air of the quartz ampoule of transmitter.

In addition, it should be noted that the heat energy that discharges simultaneously with photochemical energy is tending towards making the article drying that suffers radiation.If the example that is applied as with printing industry, radiation appliance 10 each zone of the printing product that will be aggregated not also on the radiation paper very well then, in this case, substrate (for example paper) is exposed, the part that air and thermal conductance cause humidity ratio descends, and this will influence the architectural characteristic of substrate.

Thereby can recently avoid dry effect by the humidity that increase is driven into product by the cooling air on the radiating surface.So, the mid portion of air to the zone that suffers radiation that is discharged from should be guided.Air nature by groove 66 advances in this zone.Be formed on the sidepiece reflector and transport letdown tank 80 between the sidewall edge of member 12 and be shaped to the exhaust guiding of the circuitous path that will form between the sidewall of member 12 and the reflector rear surface 56 to the mid-plane 24 that transports member 12.

Nature, under the prerequisite that does not deviate from framework of the present invention, various changes all are fine.

The distortion of a kind of embodiment shown in Fig. 5.When member surpassed certain-length (for example 1 meter), the thrust that is applied by the air of discharging and arrive cylindrical tube 36 from groove 66 can cause managing 36 distortion.For fear of the out of season skew of emission focus, can arrange the retainer ring 90 that has one or several spirals at regular intervals.This ring extends around pipe 36, and the circular edge 64 of process reflector 34 also passes its thickness, locates this ring fixing (high temperature modification, ceramic mould) gummed plunger (glueplug) 92 at this.

The line 94 of ring 90 has very little diameter, so that required flexibility (1/10mm reaches about 10 μ m) to be provided.It can be resisted and be higher than 900 ℃ temperature.This line can be for chromium/molybdenum, or quartz fibre preferably, and this fiber has the characteristic identical with fluorescent tube, is transparent, and has less expansion rate.

As illustrated among the embodiment, the conduit 16 that forms the rear volume that transports member can be the square-section, but also can be any geometry, and is for example circular, avette or square.

Transport member 12 can by have required machinery, any metal or synthetic material electric and thermal characteristics form.

Conduit 16 can with transport member 12 and isolate, and append on it, this can form the conduit 16 with material different with the material of member 12.Thereby, transport member and can have for example cross section of H shape, and have the groove that is used for radiation appliance and be used for the groove of the additional tubular conduit (tubular conduit) that duroplasts (duroplastics) material makes.In this structure, the fixed flange that conduit is provided is useful, and this fixed flange can not form excessive heat bridge (thermalbridge) between member and conduit.

As perpendicular to shown in the plane of tubular axis, the form of the recessed reflecting surface that is formed by two reflectors 34 can be parabola, and its focus is the axis of cylindrical tube.Pipe 36 focus of groove surfaces relatively departs from a little.Reflector 34 also can be taked to be similar to oval or parabolical shape, for example, by circular arc and/or straightway form irregularly shaped.

In addition, for the purpose of making (surface treatment), the length of reflector 34 can not surpass a certain size.In order to obtain large-sized member 12 (for example some rice), can put the adjacent part of reflector, thereby uniformly vertical reflecting surface is provided.

The launching technique of radiation is diversified.For example, the lamp of transmitter can be filled the low-pressure gas such as neon, or be arranged on the focal line alignment and in infrared and/or visible-range luminous axial filament, thereby replace the plasma generator post.Quartz ampoule can be replaced with glass tube.Pipe also needs not to be the cylindrical of strictness.

Be used for providing the inlet 20 of fluid can be placed in one of outside plunger, transporting the member longitudinal axis to conduit.It also can be placed on the side surface.It also can be positioned at the conduit longitudinal end between the middle part, in this case, it comprises a kind of distribution different with this hole naturally.

According to another kind of variant, transmitter 32 can water-cooled, and is oxidation resistant inert gas through the cooling fluid of groove 66, mainly is nitrogen.
