liquid cooling according to the invention comprises a cell structure and is for cooling a descending liquid in contact with the surfaces of these cells through a counter-current flow of a cooling gas flowing upwards through these cells, outer skins having surfaces arranged to impart movement

rotation to the ascending gas flowing through the cells.The structure is preferably constituted by an array of hexagonal cells connected to each other.The guide surfaces may TREs arranged along a generally spiral on cell surfaces.They can TREs formed by toothed!mayor extending inwardly or outwardly relative to the interior of cells.Ribs or other indentations may also TREs provided for cells, which extend transversely of the direction of flow of the liquid and are capable of breaking the threads or

referring now to Figure I of the drawings, there is shown a blank designated generally by the reference Io and which is represented as being subdivided into six

, but this is intended to be illustrative only. The six portions are separated by fold lines the I, 2, 3, 4, 5 and 6, well need include that the design represented by Figure 1 fundamental can TREs repeated laterally and as often as necessary according to the a device of the desired size! illustrated by Figure 4 and be described more completely not thereafter.The blank may TREs realized in any type suitable material, although preferred materials are plastic or aluminum sheets. In addition to the longitudinal fold lines 1 to 6, the blank also has transverse lines of serrations it extending across each wall forming one side of the blank. The transverse lines are designated by the letter

angstroms, the line AB extending between the fold lines 1 and 2 and so on up to the line FA between the fold lines 6 to L, the drawing can then TREs repeated. Further, the number of transverse lines extending across the blank and reporter inclination to vine longitudinal blank will depend both on the desired length of the complete structure honeycomb as depicted in Figure 4, and also of the desired pitch of the shape of a general spiral taken by the serrations II which, as is then described.Figure 2 is a cross-section along the line X-X of Figure 1 and shows the shape of each

!eRUs II is made in the transverse lines Aβ, SB, and so on as shown by b in Figure I in, the adjacent ends of two serrations are spaced from one another so as to allow folding of the blank along fold lines 1 to 6, such a folding occurring when the blank is pressed between two halves of a suitable matrix. Also wears the transverse serrations, ribs or serrations 12 are formed in the blank i0, these ribs or toothed!mayor extending perpendicularly, in each face of the blank portion, between adjacent the fold lines.The ribs 12 are of a LOA

taking Figure 3 of the drawings, the blank of Figure 1 is represented, by way of example only, as being designed as a single cell structure.It will be that the cell has a hexagonal cross-section and that the two transverse lines of serrations II is illustrated in Figure 1 are joined to form a continuous line, of generally spiral, inwardly facing serrations on the inner surface of the cell. Although this is not shown, it will be appreciated that the ribs 12 will be disposed in planes at right angles to the longitudinal axis of the cell.The single cell structure represented by Figure 3 is presented, exemplary

only, to show the manner in which the serrations along the lines II which can be shaped to of generally spiral when the blank is formed into a cell.Figure 4 has a number of f!years joined together to form a honeycomb structure, comprising a, . number of cells which are hexagonal in cross-section and which are joined together. Of creating the honeycomb structure of Figure 4, the blanks lo and embossments or corrugations are formed as each blank and has longitudinal dimensions and!aTs ra e sufficient to obtain the desired overall size of the honeycomb structure after these blanks were transformed into embossments or corrugations. As can be seen from Figure 4 if, in the conformation of the blanks into a number of embossments, each panel makes up a number of half-cells, it will be evident that adjacent embossed or corrugated blanks together form the hexagonal cells supplemented with the honeycomb structure and are joined together along the portions 13 which are of a double thickness than other sides of the hexagonal structure of each cell. This provides a honeycomb structure, which is

robust since it has a double thickness of material at the joints between the adjacent portions of the blanks corrugated or embossed.Despite the fact that, unlike the cell

that in operation, the structure will be disposed substantially vertically. The honeycomb structure is intended to act as filling a cooling water tower by evaporation (or as irrigation), wherein cooled water flows down in contact with the surfaces hexagonal cells.

Further, although the spiral shape is illustrated as being formed by serrations, it will be appreciated that the shape could be given constituted by a continuous bead formed on or applied to the inner surface sides of each cell.
