Definitions
- the invention relates to a method for the homogeneous, contactless cooling of hot, primarily non-continuous surfaces and a device therefor.
- cooling is required in many areas, for example, when flat plates must be cooled, but also when z. B. glass surfaces in the glass production or processor units o. ⁇ . Must be cooled.
- Previous cooling systems are either very expensive, or kept fairly simple, z. B. by the blowing of air or other fluids, especially water or oil, which is disadvantageous in that form on the surface always ungünsti ⁇ ge, uncontrolled flow conditions, which then become a problem when a special defined cooling is required ,
- the object of the invention is to provide reproducible, systematic, homogeneous non-contact cooling of primarily non-continuous hot surfaces to a defined surface temperature within a few seconds.
- the cooling media used are preferably general gases such as air gases, mixed gases, inert gases, etc., but also water or other fluids.
- the invention provides a low investment cost with ge ⁇ wrestle operating costs, high system availability, high flexibility and easy integration into existing production processes pro ⁇ should be made possible.
- the surface to be cooled can be moved by means of robots or linear drives in the X, Y or Z plane, whereby any specification of the movement paths and speeds of the surfaces to be cooled is possible.
- Preferred in this context is the Oszil ⁇ lation about a rest position in the X and Y plane.
- Os ⁇ zillation in the Z-plane is optionally possible.
- the cooling units according to the invention consist of nozzles which are arranged at a certain distance from each other.
- the Geo ⁇ geometry of the nozzle that is the outlet opening, quite simple cylindrical geometries to complex geometrically defined embodiments.
- the cooling unit is designed so that the effluent from the hot plate Me ⁇ dium finds sufficient space and thus will be no cross-flow on the surface to be cooled.
- the interspaces between the nozzles or rows of nozzles can be acted upon with an additional transverse flow in order to increase the cooling rate and thus to virtually suck off the cooling medium which flows out of the hot plate.
- this cross flow should not affect the inflowing cooling medium from the nozzle to the plate, ie the free jet.
- the flow pattern to be preferred follows on the surface to be cooled of a honeycomb-like structure.
- the cooling is preferably carried out with at least one cooling bar, wherein the cooling bar is a plate-like or cylindrical element, which can additionally taper from a base to a discharge bar, wherein in the discharge bar at least one nozzle is introduced.
- Sword here is hollow, so that the nozzle can be supplied from the hollow sword out with a cooling fluid.
- the nozzle (s) may be spaced apart from each other with wedge-like elements, whereby the wedge-like elements may also narrow the space for the flowing fluid to the nozzle.
- a plurality of swords arranged side by side, wherein the swords are offset from each other.
- the element to be cooled for.
- a plate to be cooled in this case moved, so that the movement of the plate on the one hand and the staggered arrangement of the nozzles on the other hand ensures that the cooling fluid all areas of the plate over ⁇ flows, so that a homogeneous cooling is achieved.
- the invention is exemplified erläu ⁇ tert reference to a drawing. It show here
- Figure 1 is a plan view of a plurality of parallel zuei ⁇ nander arranged nozzle swords;
- Figure 2 shows the arrangement of the nozzle blades according to the section AA in Figure 1;
- 3 shows a longitudinal section through a nozzle sword entspre ⁇ accordingly the section line CC in Figure 2;
- Figure 4 shows the detail enlargement D of Figure 3 showing the nozzles
- FIG. 5 shows the arrangement of the nozzle blades in a schematic perspective view
- Figure 6 shows an enlarged detail of the edge region of the nozzle swords with an offset within the sword assembly
- Figure 7 is a perspective view of an inventive
- Figure 9 is a view of the invention cooling fenders in the interior thereof;
- Figure 10 indicates the cooling blades with the nozzles, showing a plate to be cooled with the temperature distribution and the fluid temperature distribution;
- FIG. 11 shows the arrangement of Figure 10, showing the VELOCITY ⁇ speed distribution;
- FIG. 12 schematically shows the arrangement of two opposing ones
- Cooling boxes of a plurality of staggered according to the invention cooling blades and a moving carriage for moving an object to be cooled.
- the cooling device 1 has at least one cooling blade 2.
- the cooling blade 2 has a long stretched flap-like construction and has a cooling blade base 3, two cooling ⁇ heavy broad sides 4 extending away from the cooling blade base, two cooling blade narrow sides 5 connecting the cooling blade broad sides, and a free nozzle edge 6.
- the cooling blade 2 is hollow with a cooling-plate cavity 7, the cavity being surrounded by the cooling-side broad sides 4, the cooling-blade partial sides 5 and the nozzle edge 6, the cooling-off blade being 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, wherein the cooling blade frame 8 can be placed on a hollow Fluidzu Glasskasten.
- the cooling blade frame 8 In the region of the nozzle edge 6 is a plurality of nozzles or
- nozzle channels 11 extend into the cavity 7, which spatially separate the nozzles from each other, at least in the region of the nozzle edge 6.
- the nozzle channels are preferably wedge-shaped in cross-section, so that the nozzle channels or nozzles by wedge-shaped webs 12 from each other are separated.
- the die channels are formed from ⁇ that they dilate the cavity 7 out, so that a fluid flowing in is accelerated by the constriction of the nozzle channels.
- the cooling-shaft broad sides 4 may be formed converging from the cooling-plate base 3 toward the nozzle edge 6, so that the cavity narrows towards the nozzle edge 6.
- the cooling-sword partial sides 5 can be designed to converge or divergent.
- At least two cooling blades 2 are provided, which are arranged parallel to each other with respect to the broad sides, wherein the cooling blades 2 are offset with respect to the distance of the nozzles 10 by half a nozzle distance from each other.
- cooling blades 2 may be present.
- the nozzles 10 may, based on the extension of the nozzle edge, also be elongated aligned with the nozzle edge, but the nozzles may also be round, oval in alignment with the nozzle edge or oval transversely to the nozzle edge six, eight or polygonal.
- H ⁇ 6 x DH, especially 4 to 6 x DH
- Oscillation half the distance between two cooling blades in X, Y (possibly Z)
- a device for cooling (FIG. Example, two arrangements of cooling blades 2 in a cooling blade frame 8, wherein the cooling blade frame 8 with corresponding Fluidzuure- ments 14 and in particular on the side facing away from the cooling blades 2 are formed with a fluid box in which pressurized fluid is present, in particular by the supply pressurized fluid.
- a moving device 16 is provided, wherein the moving device is adapted to one to can lead cooling body between the opposing cooling sword assemblies so that can be acted on both sides cooling on the body to be cooled.
- the distances of the nozzle edges 6 to be cooled body amount to z. B. 5 to 250 mm.
- the cooling ⁇ pattern moves according to Figure 10 over the surface of the body to be cooled, wherein the effluent from the hot body medium between the Cooling Swords 2 finds enough space to escape and thus no crossflow on the surface to be cooled is formed.
- the intermediate spaces can be acted upon by corresponding flow media with an additional transverse flow in order to suck off the medium flowing on the hot body between the swords.
