Definitions

  • the invention relates to a built-in element for installation in a cavity through which a fluid can flow, for example for installation in a trickle cooler, such as a cooling tower or the like.
  • trickle coolers Built-in elements for trickle coolers are known in various configurations. Decisive for such installation elements, for example, on the one hand, a certain turbulence and guidance of the cooling medium, for example air, and on the other hand, a relatively large residence time and surface of the fluid to be cooled, such as water.
  • An example of a trickle cooler is the cooling tower of a power plant.
  • corrugated plastic film packages or packages of corrugated plastic lattice mats are used as installation elements, through which the top of the cooling tower sprayed fluid to be cooled, namely water, drop-shaped down passes and flows on the films or bars under magnification of its surface along and in contact with which takes place due to the chimney effect cooling air flow and is cooled.
  • the invention has for its object to provide an alternative installation element for a permeable by a fluid cavity, which is characterized by improved efficiency with relatively low material usage.
  • the invention proposes a built-in element for a cavity through which a fluid can flow, for example a cooling tower, the installation element being provided with the features of claim 1; individual embodiments of the invention are the subject of the dependent claims.
  • the installation element according to the invention has a plurality of contiguous molded plastic mats, which have a grid structure and are provided with a plurality of adjacent half-tube sections.
  • Each half-tube section has struts extending transversely to its longitudinal extension, with pins protruding therefrom in the longitudinal direction of the half-tube sections, with projections projecting therefrom in turn.
  • the half-tube sections of two adjacent plastic mats form individual tubes, which in a certain way serve to guide the air.
  • the branched struts there is a distribution of the fluid to be cooled and the drainage on the mounting element to a continuous division of individual larger drops into smaller drops.
  • the installation element By extending in the longitudinal direction of the half tube sections struts the installation element is given the necessary stability.
  • the plastic mats of a built-in element (plastic mat package) are held together by extending transversely to the longitudinal extent of the tube sections rods with each other, whereby the entire package receives further stability.
  • the juxtaposed plastic mats can be mutually connected to each other frictionally (positively, cohesively or frictionally).
  • pin-hole fasteners, cold-formed or latching interlocking fasteners or welds or bonds are suitable.
  • each plastic mat has a plurality of in the longitudinal extension of the half-tube sections successive and transversely offset half-tube sections.
  • the offset is about half the width of the half tube sections.
  • the staggered half tube sections are thus approximately "in gap" to each other.
  • the axial extensions (length) of the individual longitudinally successive and laterally offset half-tube sections are expediently of different lengths. This makes it possible, by relative rotation by 180 ° adjacent plastic mats to connect them with overlap of their respective half-tube sections together.
  • the offset areas of a plastic mat ie those areas within which the offset of successive half-tube sections of a plastic mat takes place, are then opposite to half-tube sections of the adjacent plastic film. This further increases the stability of the entire installation element, since in the displacement areas inclined struts could affect the stability of the individual plastic mats.
  • the half-tube sections of the plastic mats of the installation element according to the invention may in principle have any possible cross-sectional shape.
  • FIG. 1 A perspective view of a built-in element 10 according to the invention, which consists of a plurality of juxtaposed molded plastic mats 12 with a plurality of juxtaposed and laterally offset to each other half-tube sections 14,16 and 18 and with a plurality of end quarter-tube sections 20 and 22 according to Fig. 2 is built in is Fig. 1 shown.
  • Adjacent plastic mats 12 provided with grid or strut structures are each arranged opposite one another, so that the installation element 10 has a plurality of rows of adjacent tubes 24 offset along their extension.
  • the plastic mats 12 are interconnected by (pull) rods 25, which in Fig. 1 is indicated.
  • Each plastic mat 12 has longitudinal struts 26, 28 and 30 extending between adjacent half-tube sections and edge struts 32 extending along the longitudinal edges. Adjacent longitudinal struts are interconnected by arcuate transverse struts 34. Of these cross struts 34 protrude in the longitudinal direction of the half-tube sections pin 36, which in turn are provided with protruding projections 38.
  • the end-side Hafbröhrenabête 14 and the end quarter-tube sections 20 are arranged laterally offset from the central half tube sections 16, wherein the central half tube sections 16 are arranged laterally offset relative to the end half tube sections 18 and the end quarter tube sections 22.
  • two transition regions 40 are formed per plastic mat 12, in which the longitudinal struts 26 merge via obliquely extending transition struts 42 and the longitudinal struts 28 via oblique transition struts 44 into the longitudinal struts 30.
  • the region defined by the transition struts 42 and 44 area be closed flat.
  • the areas between the arcuate transverse webs 34 are basically open. But here, too, it is conceivable in principle, if individual of these areas are closed. It is also possible for the pins 36 branched off from arcuate transverse struts 34 to be directed towards one another on both sides of the transverse struts 34 or relative to adjacent transverse struts and possibly also to engage in one another. It is useful if the pin 36 so as in Fig. 2 shown, adjacent arcuate transverse struts 34 do not interconnect. However, it is possible that connecting struts between adjacent arcuate transverse struts 34 are present. Furthermore, the end-side half-tube sections 14 have a greater axial extent than the opposite end-side half-tube sections 18. This applies correspondingly to the end quarter-tube sections 20 and 22.
  • FIGS. 3 and 4 show two alternative ways of composing adjacent grid-like plastic mats 12. While in the situation according to Fig. 3 the transition regions 40 of the juxtaposed plastic mats 12 are opposite each other, these transition regions 40 in the assembly situation according to Fig. 4 offset in the axial direction of the half and quarter tube sections to each other.
