COOLING TOWER SPRINKLER Russian patent published in 2009 - IPC F28F25/08 

FIELD: heating.

SUBSTANCE: invention relates to recycling water supply, namely to structural elements of cooling towers and other units for heat-mass exchange between liquid and gaseous media. A cooling tower sprinkler consists of packaged vertically set sheets with parallel crimps which are fixed in respect to each other by spacing hubs and fastening elements passed through the latter so that to form a zigzag passage between the sheets. The cross-section of the crimps is of broken line shape forming a faceted corrugated sheet. The broken line sections forming the sheet crimps in the cross-section are of the same length and are inclined to each other at the angle of 60°, the broken line sections forming tops and valleys of the crimps are parallel to each other. The broken line sections forming the crimp tops of the one sheet are placed in the same plane as the broken line sections forming the crimp valleys of the adjacent sheet. The maximal distance between the parallel broken line sections forming crimps of adjacent sheets amounts to 0.87 of the length of the sections forming the sheet crimps and the minimal distance between the parallel broken line sections forming crimps of adjacent sheets amounts to 0.5 of the maximal distance between the parallel sections of the adjacent sheets forming the sheet crimps. Tops and valleys are made at each facet in the form of alternating rows and those in the adjacent rows are set at the angles opposite to a vertical; each top or valley is inclined at the angle of 30°-45° to the vertical; height of each top and depth of each valley amounts to 0.05-0.2 of the facet width and the length of each top or valley amounts to 0.25-0.8 of the facet width; at least 3 parallel to each other tops or valleys are made at each facet in each row. The crimps formed in the sheet plane are vertical or inclined at an acute angle to the vertical.

EFFECT: increasing heat-mass exchange intensity and improving the reliability of the cooling tower sprinkler performance.
