PLATE OF SPRINKLER OF HERRING-BONE STRUCTURE AND SPRINKLER UNIT OF COOLING TOWER (VERSIONS) Russian patent published in 2011 - IPC F28F25/08 

FIELD: power industry.

SUBSTANCE: plate of sprinkler of herring-bone structure, which is made from polymer material, for example PVC, includes ruffles in the form of continuous wave; at that, each ruffle is made in the form of zigzag-shaped sequence of short channels similar as to length and section and oriented towards each other at equal angle of not less than 90° and not more than 180°, and ratio of height of ruffle to length of rib of short channel along zigzag-shaped guide is at least 2.5. On the plate base of sprinkler of herring-bone structure there assembled are various versions of sprinkler unit of cooling tower. As per the first and the second version of design the sprinkler unit includes many vertically installed and alternating plates of herring-bone structure and flat plates with formation of zigzag-shaped channels identical as to height of sprinkler unit. As per the second version of design, in sprinkler unit the even corrugated plates of sprinkler of herring-bone structure are turned about horizontal axis through 180° relative to even corrugated plates of sprinkler of herring-bone structure. As per the third version, sprinkler unit includes only plates of herring-bone structure, which are turned relative to each other through 180° and installed so that they have point contact between each other at point of convergence of zigzag-shaped ribs and along each zigzag-shaped rib, and at that, they form through cross zigzag-shaped channels in vertical and horizontal directions, and connecting tubes are installed in places of point contact along zigzag-shaped ribs of corrugated plates of sprinkler of herring-bone structure.

EFFECT: invention allows increasing water cooling efficiency in sprinkler of cooling tower by enlarging inter-phase surface.
