- ABSTRACT [30] Foreign Application Priority Data
- a device for reflecting electromagnetic radiation from an elongated radiation source comprising a profiled holder Nov. 13, 1968 Sweden ..15424/68 formed as a body having a cavity that provides a supporting surface for a reflecting metal strip.
- the supporting surface is h g gg shaped to Partially surround said radiation source and the sur.
- "j face defines a groove preferably arranged behind the radiation
- the reflecting metal strip is secured to the holder by 2l9/352 L f stop members integral with the body of the holder which elastically inflect the reflecting metal strip against the supporting surface.
- the width of the reflecting metal strip is chosen so [56] References Cited that the reflecting metal strip is kept permanently flexed into UNITED STATES PATENTS the groove under elastic deformation in its mounted position 2 5 I6 660 7/1950 v 240/51 H throughout the operating temperature range.
- the reflectors are often provided with a glass window, or at higher thermal loading with a window of quartz.
- This window is in the first hand mechanically very fragile and in second hand it is extremely sensitive for impurities, which due to the high temperature can easily be burnt into the material, which rapidly loses its transparency resulting in a lowering of the efficiency of the reflector.
- the present invention refers to a new construction of such a reflector device for reflection of radiation transmitted from a cylindric or linear radiation source preferably at high temperature, disposed so that the main axis of the reflection surface is substantially parallel with the longitudinal axis of the radiation source whereby not only these previously mentioned drawbacks have been eliminated but furthermore simultaneously other essential technical effects have been achieved.
- the invention also refers to a system for cooling of the reflector body, reflector surface and radiation source.
- the reflector device according to the invention which is especially, although not limitative, suitable for infrared radiation devices, is characterized in that the holder is formed as a body with a supporting surface for a radiation reflecting metal strip, this body at parallel edges being provided with stopmembers each for engagement with one of parallel rims of the reflecting strip which is elastically inflected against the supporting surface, this supporting surface being provided with at least one groove for enabling the stripmaterial, held between said stopmembers to be flexed therein under elastic deformation, the longitudinal direction of this groove being parallel with the said main axis.
- This device thus consists substantially of a reflector body which is shaped optically-geometrically in a suitable manner and a flexible strip adapted to the same reflector body will in this way serve as a holder both for the electro magnetic radiation source and the strip.
- the strip which is resiliently fastened in the reflector body, will by its flexibility and resiliency be pressed against the geometrically shaped surface of the said body.
- the flexible metallic strip has such a surface or is possibly coated such that a reflection, which is well adapted to the radiation source in question, is produced.
- the reflector built up according to the present invention is in principle composed by a shaped body and a strip element, which can both be manufactured in continuous processes, and the elements can be cut to suitable lengths and joined in a simple manner.
- Devices manufactured in a running process will be cheaper than corresponding devices made and treated in another manner.
- the strips can easily be replaced when required, and, as this will cost only a small portion of the whole reflector, the use will be essentially cheaper than in the known devices.
- the shaped body can consist of an extruded aluminum profile and the reflection strip can consist of a cold-rolled, thin, flexible with a reflecting layer.
- the reflective metal strip is fastened in the reflector body such that the heat extension, if any, will press the strip against the reflector body, whereby the increased pressure will improve the heat transmission and the cooling of the reflective metal strip by heat conduction.
- the groove in the supporting surface should be such shaped that it will not disturb or only disturb in a small degree the geometric formation of the reflector strip against the reflector body and that it can contain the excess of material flexed into the groove under elastic deformation by the heat extension due to the fact that the reflector strip has a higher temperature than the reflector body. Also in the event that a strip is taken which is wider than the arc length of the geometrical surface of the reflector body, excessive material of the reflector strip can be flexed into the groove.
- the groove furthermore in a non-predictable manner enables a rational introducing of the reflector strip at the mounting or replacement, which, without the said recess, were impossible to carry through under fulfilment of the technically important requirement that the reflector strip shall be effectively pressed against and fill the geometric shape of the reflector body.
- the longitudinal groove is arranged substantially behind the radiation source as seen from the main direction of reflected radiation.
- stopmembers are formed integral with the said reflector body.
- two parallel fixed ledges are formed as stopmembers for the flexible reflective strip.
- the device In using a reflective strip, to be inflected against the shaped body, the device is thus provided with at least one channel, defined by the walls of the groove and the strip covering this groove.
- this channel can be used as a cooling channel for which it must be adapted for being connected to a source of cooling medium.
- a gaseous cooling medium can suitably be distributed via a centrally situated inlet.
- a number of interconnected parallel channels can be formed in the strip supporting surface of the body; in that case the device is provided with a net of channels.
- a condition for the placing and shaping of these channels is of course that they will not appreciably influence the shaping of the reflector strip in the reflector body, also with regard taken to the placing of the reflector strip with its resilient contact with the reflector body.
- the radiation source may be a tubular incandescent lamp, consisting of a quartz tube, which in its center has a helically wound filament.
- the electrical lead-out conductors are situated at the ends of the quartz tube and hermetically sealed thereto at a foliated portion of the conductors.
- quartz and metal have essentially differing heat expansion coefficients, it is important to keep their temperature in use as low as possible so as to increase the life-length of the lamp.
- theaforementioned channel is so shaped that the cooling medium is applied to the both ends of the radiation source. In the simpliest way this may be produced thereby that the reflector strip has its ends close to the ends of the lamps, whereby the cooling medium will flow over the ends of the lamp.
- the reflector device is characterized in that the reflector strip at places where it covers the cooling channel or channels, is provided with a number of openings all over the length of the channel for distributing the cooling medium over the reflective surface of the strip.
- the openings are associated with gill-shaped lugs forced through the strip, which are arranged and directed so as to guide the cooling medium to sweep along the surface of the reflecting strips in paths transversal to the longitudinal axis of the radiation source.
- Cooling medium under pressure escaping from these openings will then due to known physical laws not only cool the reflector body and the reflector strip but also the radiation source itself which is directly and or indirectly influenced by the said cooling medium.
- the now heated cooling air can leave the reflector in its optical opening whereby the escaping gaseous medium besides the cooling effect on the whole system will also act as a barrier for dirt, dust or other particles or substances in the surroundings, which are harmful for the surfaces of the reflector, and furthermore in such drying processes or other processes, where the radiator in question is used for vaporization or release of other substances in the radiated medium, act to effectively remove these and thereby in the case of drying will appreciably accelerate the process.
- the cooling effect will be mainly the same if the reflector body at cooling with a gaseous medium is provided with a window in its optical opening, which is transparent for the radiation in question.
- the ends of the reflector will of course allow free escape for the cooling medium.
- the said reflector bodies are further shaped such that they can be joined together to a system of reflectors, without need for any outer supporting construction elements.
- the reflector bodies can for this purpose for example be provided with corresponding T-shaped grooves or grooves of other shape, which together with a suitably wedge-shaped profile element adapted to the said grooves will form a rigid and supporting joint.
- a reflector is achieved, in which the optically reflecting surface due to the construction can easily be replaced when desired.
- the geometrically shaped surface of the reflector body can furthermore be provided with thin, but nevertheless effective thermal insulating layers, which prevent the heat arising in the reflector strip due to the absorbed radiation energy to be led further to the reflector body and thus in a reflector operating at a low power can serve as a safety measure for the case that the cooling air of some reason should be interrupted.
- the thermal insulating layer can also consist of a thin insulating foil or the like of thin heat-resistant material as for example ceramic fibre.
- the reflector body can of course also be provided with cooling flanges extending in the length direction of the reflector, which flanges increase the heat transmitting surface.
- the reflector body is provided with separate further channels, through which liquid cooling medium can flow. These channels can also be made in an extruded aluminum profile, if this form for realizing the invention is selected.
- FIG. 1 shows a sectional view through a reflector as seen perpendicular to its length direction
- FIG. 2 shows a similar view as in FIG. 1 except a reflector strip of differing structure
- FIG. 3 shows an end part of the reflector device taken along the lines IIIIII in FIG. 2, and
- FIG. 4 shows a section taken along the lines IV-IV in FIG. 2.
- the reflector device in FIG. 1 shows a reflector body 1 in which an elastically flexible reflective strip 2 is attached.
- the reflector strip 2 is held flexed against the supporting surface between the parallel rims of the body 1, which are provided with protruding ribs 3 and 4 which form two stopmembers for the strip 2.
- the reflector device is also provided with a protective transparent plate 5.
- this reflector body is also arranged an elongated radiation source of which the filament is indicated by 6 and the quartz glass envelope by 7.
- This source may be formed as a tubular, double-ended infrared heating lamp.
- the reflector body 1 is provided with a cavity of parabolic, elliptic or any other shape. Its main axis is parallel with the axis of the elongated light source 6, 7.
- an elliptically adapted reflector body the geometric shape of which is adapted to the shape of the source 6, 7 is elected. Of this elliptic surface the foci are arranged at the centre of the filament 6 and at 8.
- the supporting surface of the body 1 is provided with a longitudinal groove 9, extending all over the length of that body 1.
- This groove 9 functions as an expansion groove, in which a part 10 of the strip can be flexed under the influence of elastic deformation. This can occur as said in the ingress of the specification if the strip as placed between the stopmembers 3 and 4 is a little oversized, or if the strip is expanding under the influence of differing heat expansion between the materials of the body 1 and the strip 2. In all cases the groove 9 functions as a space enabling a compensation for deformation of the strip 2.
- the walls of the groove 9 together with the strip form a channel which can be connected to a source of cooling medium at a central duct 11.
- FIG. 2, 3 and 4 show another embodiment of the reflector device according to the invention, where the same references as in FIG. 1 are used for corresponding elements.
- FIG. 4 the central duct 11 is shown.
- the channel 9 two openings 14 are provided, where the air flow due to connection strips 16 of the radiation source 6, 7 or in another way is forced across the lead-in wires 6 of the lamp and to cool these parts of the lamps.
- the reflector strip is furthermore provided with a number of slits 12 formed by forcing a number of lugs 13 through the strip 2. Seen in the main axis of the reflector body 1 the lugs 13 are gill-shaped. Due to these slits air flows across the reflector surface 2, which air inter alia will draw air from the surroundings of the quartz tube 7 and thus also cause cooling of this tube in a way as appears especially from FIG. 2 especially. If the window 5 is removed, the cooling air heated by the source 6, 7 can escape through the optical opening and be used for drying purposes.
- FIG. 15 designates external grooves for enabling adjacent reflector devices to be joined to a module system. This can be done by sliding a connection member 17 in the grooves 15 of adjacent bodies 1 (see FIG. 1). For connection two reflector bodies such that their main axis become flush a bar 19 is slid in the grooves 15 of adjacent bodies 1.
- a reflector device for an elongated radiation source comprising a profiled holder formed as a body having an elongated cavity, said body having a surface defining said cavity that is shaped to partially surround said radiation source, said surface having a reentrant portion defining a longitudinally extending groove adjacent said cavity, the main axis of the cavity and the longitudinal axis of said groove being substantially parallel to each other and with the longitudinal axis of said radiation source, a radiation reflecting metal strip within said cavity, and stop members provided at edges of said body adjacent the cavity for engagement with corresponding edges of said reflecting metal strip, thereby causing said reflecting metal strip to elastically inflect against said cavity surface, said reflecting metal strip having a width which keeps said reflecting metal strip permanently flexed into the groove under elastic deformation while in a mounted position.
- a reflector device as claimed in claim 1 further comprising a source of a cooling medium, cooling channels within said body for distributing said cooling medium, and means for passing said cooling medium over said reflecting metal strip, said means comprising openings in said reflecting metal strip at locations over the length of the cooling channels where said reflecting metal strip covers the cooling channels, and a plurality of lugs forced through the reflecting metal strip at said locations to form gill-shaped guiding members for the cooling medium emanating through the openings, said lugs being arranged and directed to guide the cooling medium to sweep along the surface of the reflecting metal strip in paths traverse to the longitudinal axis of the radiation source.
- a reflector device as claimed in claim 1 further comprising a viscous heat conducting material between the cavity surface and the reflecting metal strip to increase the heat transfer from the reflecting metal strip to the body of the holder.
