HEAD PIECE FOR HEAT AND MASS EXCHANGER Russian patent published in 2009 - IPC F28F25/08 

FIELD: mechanics.

SUBSTANCE: head piece for heat and mass exchanger consists of long modular hollow elements with a framed web and cross section in the form of regular petal shape, at that, tops of petals and cavities between them are rounded, at that, the above elements are made in cross section in the form of five-petal shape the external outline of cross section of which is formed by a circle with five cavities obtained by having crimped a cylindrical workpiece formed by cross fibres from thermoplastic, at that, maximum width of cavities in cross section of each element is less than maximum width of petals; external outline of petals is formed by external arcs of a circle, the ends of which are mated by means of arcs of a circle and a straight line with arcs of circle forming cavities between external arcs, and inner diametre of the element, which is formed by arcs of circle comprising cavities, is 0.25 to 0.4 of outer element diametre formed by external arcs of circle.

EFFECT: simplifying assembly procedure of head piece units and increasing efficiency of water spray in a cooling tower.
