Definitions

  • the invention relates to a cooling tower plate made of fiber cement or the like, which is structured by rows of elevations on one surface and opposing depressions on the other surface, the height of the elevations and depressions being less than the substantially uniform thickness of the plate is.
  • Cooling tower plates of this type are e.g. B. from DE-U-8302704 and are used extensively in cooling towers, for example of power plants, to be able to recool large quantities of cooling water through the ambient air.
  • the cooling tower plates are often suspended in packages within a cooling tower, so that their surfaces run in vertical planes.
  • the water to be cooled is sprinkled or sprayed onto the top of the cooling tower plates. It then runs in countercurrent along the plate surfaces against cooling air directed downwards. There it either meets additional cooling tower plates or is collected for reintroduction into the cooling process.
  • the surface structure of such plates is primarily important for the cooling effect.
  • the water should have a large surface available for wetting and the water should not flow laminarly over the surfaces so that an optimal cooling effect is achieved.
  • the production of cooling tower plates with such a structure is complex due to the shapes required for this.
  • the invention has for its object to propose a structured cooling tower plate that has good heat exchange properties and yet inexpensive, for. B. by rolling.
  • a cooling tower plate of the type mentioned is proposed. It is distinguished according to the invention in that the elevations are spaced, flattened or rounded points on their heads, which the corresponding depressions are opposite, that on each surface two corresponding rows of depressions are provided on both sides next to two immediately adjacent rows of dots, and that both the points and the depressions of each line pair are offset from one another in the line direction.
  • the plate is designed to be slightly undulating perpendicular to the row direction.
  • a three-dimensional heat sink is known, which is designed in the form of a hollow body with several levels.
  • the layers of the individual levels have elevations and depressions, the height of which is a multiple of the material thickness of the layers.
  • a cooling tower plate 1 has a basic thickness of about 5 mm and a surface 2, which is shown in FIG. 1 and a surface 3 opposite this for this purpose, indentations or depressions 5 running in rows are structured.
  • the elevations or points 4 have approximately the form of small hills, which protrude over from the Platteno- f Smile Friend 2 and have a flattened or rounded surface.
  • Each elevation or point 4 on one plate surface 2 is opposite a depression 5 in the area of this point 4 in the other plate surface 3.
  • rows 2 of points 4 and depressions 5 are provided in pairs on each surface 2, 3. 1 shows, from top to bottom, first two lines 6, 7 of wells 5, then two lines 8, 9 of wells 4, then again two lines 10, 11 of wells 5 and finally one line 12 of wells 4. Points 4 of each pair of dot rows 8, 9 are offset from one another in the row direction - and of course perpendicularly thereto. The same applies to the depressions 5 in the two adjacent rows 6, 7 and 10, 11 of depressions 5, respectively. The result is the image of a zigzag-shaped row of dots in the area of each pair of dot rows 8, 9 and a corresponding zigzag-shaped course of the indentations or depressions 5.
  • each elevation or point 4 is followed by an indentation or depression 5, which in turn is followed by a point 4.
  • the cross section shown in FIG. 2 through the cooling tower plate 1 runs exactly along the line 7 from the section of the surface 2 of the cooling tower plate 1 shown in FIG. 1.
  • the depressions 5 of the line 7 in FIG. 2 can be clearly seen .
  • Each depression 5 corresponds to an elevation or a point 4 on the surface 3.
  • the material of the cooling tower plate 1 is curved upward between the depressions 5 of the row 7.
  • the points 4 on the surface 3 can be recognized, which correspond to the depressions 5 of the row 6 on the surface 2.
  • the shape of the depressions 5 or points 4 can be clearly seen.
  • the structure of the plate according to the invention is versatile and can be used with advantage not only for cooling towers, but quite generally as a trickle plate.

Abstract

Une plaque (1) pour tour de réfrigération en fibrociment ou matériau similaire possède des surfaces (2, 3) structurées par des élévations (4) disposées par lignes et des creux (5) adjoints à celles-ci. L'eau circulant le long de ces plaques a à sa disposition une grande surface en vue du mouillage et elle ne s'écoule pas non plus laminairement sur les surfaces. La plaque présente de bonnes propriétés d'échange thermique et sa fabrication est peu coûteuse, parce que de chacune des deux surfaces font saillie des points aplanis ou arrondis disposés par lignes ou autres, qui sont situés vis-à-vis des lignes similaires de creux, et que chaque surface de plaque possède une multitude aussi bien de lignes de points que de lignes de creux approximativement parallèles.

Claims (2)

1. Plaque en fibrociment ou matériau similaire pour tour de réfrigérateur, cette plaque étant façonnée sur une surface avec des bossages s'étendant parallèlement entre eux suivant des lignes et sur l'autre surface avec des renfoncements opposés aux bossages, la hauteur des bossages et des renfoncements étant inférieure à l'épaisseur, sensiblement constante, de la plaque, caractérisée en ce que les bossages forment des points espacés (4) à tête aplatie ou arrondie, les renfoncements correspondants (5) étant opposés à ces points, en ce que sur chaque surface (2, 3) sont chaque fois prévues, d'un côté et de l'autre de deux lignes de points (4) immédiatement voisines (8, 9), deux lignes correspondantes (6, 7, 10, 11) de renfoncements (5) et en ce que les points (4) ainsi que les renfoncements (5) de chaque couple de lignes sont décalés entre eux dans la direction des lignes.
2. Plaque pour tour de réfrigération selon la revendication 1, caractérisé en ce qu'elle présente une forme légèrement ondulée perpendiculairement à la direction des lignes. 1
