Definitions

  • the invention relates to a method for homogeneous, contactless cooling of hot, primarily not endless surfaces, and a device therefor.
  • cooling is required in many areas, for example when flat plates have to be cooled, but also when e.g. B. glass surfaces in glass manufacture or processor units or the like must be cooled.
  • Previous cooling systems are either very complex, or kept quite simple, e.g. B. by blowing air or with other fluids, especially water or oil, which has the disadvantage that always unfavorable, uncontrolled flow conditions form on the surface, which become a problem when a specially defined cooling is required.
  • a cooling device for moving steel strips in which there are a plurality of cooling strips located transversely to the running direction of the steel strip and the cooling strips via cooling directed towards the steel strip have glands from which a cooling fluid can be jetted onto the moving steel strip.
  • a device which has a plurality of cooling strips which are also executed to form a moving steel strip and act in a manner comparable to the prior art already mentioned on the steel strip with jets from a cooling fluid, the moving steel strip having rollers is tensioned to prevent movements that deviate from the unidirectional running movement of the belt.
  • the object of the invention is to create reproducible, systematic, homogeneous, contact-free cooling of primarily not endlessly hot surfaces to a defined surface temperature within a few seconds.
  • Another object is to create a process for the reproducible, systematic, homogeneous, contact-free cooling of primarily non-endlessly hot surfaces to a defined surface temperature within a few seconds.
  • cooling media used are preferably general gases such as air gases, mixed gases, inert gases etc., but also water or other fluids.
  • the surface to be cooled can be moved in the X, Y or Z plane by means of robots or linear drives, any desired specification of the movement trajectories and speeds of the surfaces to be cooled being possible.
  • the oscillation around a rest position in the X and Y planes is preferred. Further oscillation in the Z plane (i.e. the height) is optional.
  • Cooling on one or both sides is also easily possible.
  • the cooling units according to the invention consist of nozzles which are arranged at a certain distance from one another.
  • the geometry of the nozzles i.e. the outlet opening, ranges from simple cylindrical geometries to complex geometrically defined designs.
  • the cooling unit is designed in such a way that there is sufficient space for the medium flowing out of the hot plate so that there is no crossflow on the surface to be cooled.
  • the gaps between the nozzles or rows of nozzles can be subjected to an additional cross flow in order to increase the cooling rate and thus quasi suction the cooling medium that flows from the hot plate.
  • this cross-flow should not impair the cooling medium flowing from the nozzle to the plate, i.e. the free jet.
  • the flow pattern to be preferred follows a honeycomb-like structure on the surface to be cooled.
  • the cooling is preferably carried out with at least one cooling sword, the cooling sword being a plate-like or cylindrical element which can additionally taper from a base to an outflow bar, at least one nozzle being introduced in the outflow bar.
  • the sword is hollow, so that the nozzle can be supplied with a cooling fluid from the hollow sword.
  • the nozzle (s) can be spatially spaced apart from one another with wedge-like elements, wherein the wedge-like elements can also narrow the space for the flowing fluid towards the nozzle.
  • a plurality of swords are preferably arranged next to one another, the swords being offset from one another.
  • the offset arrangement also results in cooling with offset points with respect to one another, the points cooling homogeneously into one another and the outflowing fluid being sucked in and removed in the region between two swords.
  • the element to be cooled e.g. B. a plate to be cooled, moved here, so that the movement of the plate on the one hand and the offset arrangement of the nozzles on the other hand ensures that the cooling fluid flows over all areas of the plate, so that homogeneous cooling is achieved.
  • the cooling device 1 has at least one cooling sword 2.
  • the cooling sword 2 is of elongated flap-like design and has a cooling sword base 3, two cooling sword broad sides 4 which extend away from the cooling sword base, two cooling sword narrow sides 5 which connect the cooling sword wide sides, and a free nozzle edge 6 .
  • the cooling sword 2 is hollow with a cooling sword cavity 7, the cavity being enclosed by the cooling sword broad sides 4, the cooling sword narrow sides 5 and the nozzle edge 6, the cooling sword at the base 3 being open.
  • the cooling sword base 3 With the cooling sword base 3, the cooling sword is inserted into a cooling sword frame 8, wherein the cooling sword frame 8 can be placed on a hollow fluid supply box.
  • a plurality of nozzles or openings are introduced, which extend into the cavity 7 and thus allow fluid to flow out of the cavity to the outside through the nozzles 10.
  • Nozzle channels 11 extend from the nozzles into the cavity 7, which spatially separate the nozzles from one another at least in the region of the nozzle edge 6.
  • the cross-section of the nozzle channels is preferably wedge-shaped, so that the nozzle channels or nozzles are separated from one another by wedge-shaped webs 12 are separated.
  • the nozzle channels are preferably designed in such a way that they expand towards the cavity 7, so that an inflowing fluid is accelerated by the narrowing of the nozzle channels.
  • the cooling sword broad sides 4 can be designed to converge from the cooling sword base 3 to the nozzle edge 6, so that the cavity narrows towards the nozzle edge 6.
  • the narrow sides 5 of the cooling sword can be designed to be convergent or divergent.
  • At least two cooling swords 2 are preferably provided, which are arranged parallel to one another with respect to the broad sides, the cooling swords 2 being offset with respect to one another by half a nozzle spacing with respect to the spacing of the nozzles.
  • the nozzles 10 can also be designed to be oblong in alignment with the nozzle edge, but the nozzles can also be round, oval in alignment with the nozzle edge or oval, hexagonal, hexagonal or polygonal.
  • nozzles are also elongated with respect to the longitudinal extent of the nozzle edge, in particular elongated oval or elongated polygonal, there is a rotation of an emerging fluid jet ( Figures 10 , 11 ), whereby an offset arrangement by half a nozzle distance results in a cooling pattern on a plate-like body ( Figure 10 ), which is offset accordingly.
  • the corresponding speed profile also gives a corresponding distribution ( Figure 11 ).
  • a cooling device ( Figure 12 ) has e.g. B. two arrangements of cooling swords 2 in a cooling sword frame 8, the cooling sword frame 8 with corresponding fluid feeds 14 and in particular on the side facing away from the cooling swords 2 are formed with a fluid box in which there is fluid under pressure, in particular by the supply under pressure standing fluid.
  • a movement device 16 is provided, the movement device being designed such that it closes one can lead cooling body between the opposing cooling sword arrangements so that the body to be cooled can have a cooling effect on both sides.
  • the distances between the nozzle edges 6 to the body to be cooled are z. B. 5 to 250 mm.
  • the cooling pattern moves in accordance with a relative movement of either the device for cooling to a body to be cooled or vice versa, in particular an oscillating or oscillating movement Figure 10 over the surface of the body to be cooled, the medium flowing away from the hot body finding sufficient space between the cooling swords 2 to flow off and thus no crossflow occurring on the surface to be cooled.
  • the intermediate spaces can be acted upon with an additional cross-flow with appropriate fluid in order to suck off the medium flowing onto the hot body between the swords.
