  • the invention relates to a method for homogeneous, contactless cooling of hot, primarily non-endless surfaces and to an apparatus therefor.
  • cooling processes Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath Hardly a man or woman draws a breath are needed in many areas, for example when it is necessary to cool flat plates, but also when it is necessary to cool glass surfaces, for example in glass production, or to cool processor units and the like.
  • Prior cooling systems are either very expensive or are kept quite simple, e.g. by blowing air or other fluids such as water or oil; this entails the disadvantage that unfavorable, uncontrolled flow conditions always occur on the surface, which then become a problem when a particularly defined cooling is required.
  • non-homogeneous surface temperatures also cause warpage.
  • U.S. Pat. No. 5,871,686 has disclosed an apparatus for cooling moving steel strips, which has a plurality of cooling fins extending transversely to the travel direction of the steel strip, and the cooling fins have cooling nozzles, which are aimed at the steel strip and which can blow a cooling fluid at the moving steel strip.
  • US 2011/0018178 A1 has disclosed a comparable apparatus, but which instead of cooling fins with nozzles, has a plurality of cooling cylinders that are aimed at the strip and whose free ends have outlet openings for a fluid that is to be supplied to a moving steel strip.
  • DE 69833424 T2 has disclosed an apparatus, which has a plurality of cooling fins that are likewise aimed at a moving steel strip and, in a way that is comparable to the above-mentioned prior art, act on the steel strip with jets of a cooling fluid, with the moving steel strip being tensioned by means of rollers in order to prevent movements that deviate from the unidirectional traveling movement of the strip.
  • the object of the invention is to achieve reproducible, systematic, homogeneous, contactless cooling of primarily non-endless hot surfaces to a defined surface temperature within a few seconds.
  • the object is attained with an apparatus having the features of claim 1 .
  • Another object of the invention is to produce a method for re-producible, systematic, homogeneous contactless cooling of primarily non-endless hot surfaces to a defined surface temperature within a few seconds.
  • the object is attained with an apparatus having the features of claim 8 .
  • cooling mediums used are preferably common gases such as air gases, mixed gases, inert gases, etc., but can also be water or other fluids.
  • the invention should make it possible, for a low investment cost and with low operating costs, to achieve high system availability, high flexibility, and simple integration into existing production processes.
  • the surface to be cooled can be moved by means of robots or linear drives in the X, Y, or Z plane, it being possible to preset any movement trajectories and speeds of the surface to be cooled.
  • the oscillation is preferably around a rest position in the X and Y planes. It is optionally possible for there to be oscillation in the Z plane (i.e. in the vertical direction).
  • the cooling units according to the invention are comprised of nozzles, which are spaced a certain distance apart from one another.
  • the geometry of the nozzles i.e. of the outlet opening, reaches from simple cylindrical geometries through complex geometrically defined embodiments.
  • the cooling unit in this case is embodied so that the medium flowing away from the hot plate finds enough room and as a result, no cross flow is produced on the surface to be cooled.
  • the spaces between the nozzles and/or nozzle rows can be acted on with an additional cross flow in order to increase the cooling rate and thus suck up, so to speak, the coolant that is flowing away from the hot plate.
  • This cross flow should not interfere with the coolant flowing from the nozzle to the plate, i.e. the free flow.
  • the preferred flow pattern on the surface to be cooled should have a honeycomb-like structure.
  • the cooling preferably takes place by means of at least one cooling blade; the cooling blade is a plate-like or cylindrical element, which can also taper from a base toward an outlet strip; and at least one nozzle is mounted in the outlet strip.
  • the blade is embodied as hollow so that the nozzle can be supplied with a cooling fluid from the hollow blade.
  • the nozzle(s) can be spaced apart from one another with wedge-like elements; the wedge-like elements can also narrow the space for the flowing fluid in the direction toward the nozzle.
  • a plurality of blades is provided, situated next to one another, with the blades being offset from one another.
  • the offset arrangement likewise produces a cooling with points that are offset from one another, with the points blending into one another to produce homogeneous cooling and the emerging fluid is sucked up in the region between two blades and conveyed away.
  • the element to be cooled e.g. a plate to be cooled
  • the element to be cooled is preferably moved so that the movement of the plate one the one hand and the offset arrangement of the nozzles on the other ensures that the cooling fluid flows across all of the regions of the plate so that a homogeneous cooling is achieved.
  • FIG. 1 shows a top view of a plurality of nozzle blades arranged parallel to one another
  • FIG. 2 shows the arrangement of nozzle blades according to the section A-A in FIG. 1 ;
  • FIG. 3 shows a longitudinal section through a nozzle blade according to the section line C-C in FIG. 2 ;
  • FIG. 4 is an enlargement of the detail D from FIG. 3 , showing the nozzles
  • FIG. 5 is a schematic, perspective view of the arrangement of nozzle blades
  • FIG. 6 is an enlarged detail of the edge region of the nozzle blades, with an offset within the arrangement of blades;
  • FIG. 7 is a perspective view of an arrangement of cooling blades according to the invention, which are consolidated into a cooling block;
  • FIG. 8 is a perspective rear view of the arrangement according to FIG. 7 ;
  • FIG. 9 is a view into the interior of cooling blades according to the invention.
  • FIG. 10 depicts the cooling blades with the nozzles, showing a plate to be cooled, the temperature distribution, and the fluid temperature distribution;
  • FIG. 11 is a view of the arrangement according to FIG. 10 , showing the speed distribution
  • FIG. 12 schematically depicts the arrangement of two opposing cooling boxes composed of a plurality of cooling blades according to the invention arranged offset from one another and a moving carriage for taking an article to be cooled and conveying it through.
  • the cooling apparatus 1 has at least one cooling blade 2 .
  • the cooling blade 2 is embodied in the form of an elongated flap and has a cooling blade base 3 , two cooling blade broad sides 4 extending away from the cooling blade base, two cooling blade narrow sides 5 that connect the cooling blade broad sides, and a free nozzle edge 6 .
  • the cooling blade 2 is embodied as hollow with a cooling blade cavity 7 ; the cavity is enclosed by the cooling blade broad sides 4 , the cooling blade narrow sides 5 , and the nozzle edge 6 ; the cooling blade is open at the base 3 .
  • the cooling blade base 3 With the cooling blade base 3 , the cooling blade is inserted into a cooling blade frame 8 ; and the cooling blade frame 8 can be placed onto a hollow fluid supply box.
  • the region of the nozzle edge 6 is provided with a plurality of nozzles or openings, which reach into the cavity 7 and thus permit fluid to flow out of the cavity to the outside through the nozzles 10 .
  • nozzle conduits 11 extend into the cavity 7 , spatially separating the nozzles from one another, at least in the region of the nozzle edge 6 .
  • the nozzle conduits in this case are preferably embodied as wedge-shaped so that the nozzle conduits or nozzles are separated from one another by wedge-shaped struts 12 .
  • the nozzle conduits are embodied so they widen out in the direction toward the cavity 7 so that an incoming fluid is accelerated by the narrowing of the nozzle conduits.
  • the cooling blade broad sides 4 can be embodied as converging from the cooling blade base 3 toward the nozzle edge 6 so that the cavity narrows in the direction toward the nozzle edge 6 .
  • cooling blade narrow sides 5 can be embodied as converging or diverging.
  • At least two cooling blades 2 are provided, which are arranged parallel to each other in relation to the broad sides; with regard to the spacing of the nozzles 10 , the cooling blades 2 are offset from one another by a half nozzle distance.
  • the nozzles 10 can likewise be embodied as longitudinally flush with the nozzle edge; the nozzles, however, can also be embodied as round, oval and aligned with the nozzle edge or oval and transverse to the nozzle edge, hexagonal, octagonal, or polygonal.
  • the nozzles with regard to the longitudinal span of the nozzle edge, are likewise embodied as oblong, particularly in the form of an oblong oval or oblong polygon, this causes a twisting of an emerging jet of fluid ( FIGS. 10 & 11 ); an offset arrangement by half a nozzle spacing distance yields a cooling pattern on a plate-like body ( FIG. 10 ), which is correspondingly offset.
  • the corresponding speed profile also produces a corresponding distribution ( FIG. 11 ).
  • fluid flowing out of the nozzles 10 does in fact strike the surface of a body to be cooled ( FIGS. 10 & 11 ), but it clearly flows away, plunging between the at least two blades of the cooling apparatus 1 so that the cooling flow at the surface of a body to be cooled is not interrupted.
  • a cooling apparatus ( FIG. 12 ) has two arrangements of cooling blades 2 in a cooling blade frame 8 ; the cooling blade frames 8 are embodied with corresponding fluid supplies 14 and particularly on the side oriented away from the cooling blades 2 , are provided with a fluid box that contains pressurized fluid, in particular by means of a supply of pressurized fluid.
  • a moving device 16 is provided; the moving device is embodied so that a body to be cooled can be conveyed between the opposing cooling blade arrangements in such a way that a cooling action can be exerted on both sides of the body to be cooled.
  • the distances of the nozzle edges 6 from the body to be cooled in this case are, for example, 5 to 250 mm.
  • the cooling pattern according to FIG. 10 moves across the surface of the body to be cooled; the medium flowing away from the hot body finds enough room between the cooling blades 2 and thus no cross flow is produced on the surface to be cooled.
  • the spaces between are acted on with corresponding flow mediums by means of an additional cross flow in order for the medium flowing against the hot body to be sucked up between the blades.
