A distribution apparatus for a cooling tower has a source of liquid communicated to a plurality of branches extending from the source of liquid for transfer of a liquid to a cooling tower arrangement, where the branches are provided with a plurality of generally laterally extending protuberances providing a calming region from a generally turbulent liquid flow to produce a relatively quiescent region above a port and nozzle for stable fluid flow to a nozzle and a better controlled flow to the tower media.

A film fill-pack has a plurality of fill-sheets with an ordered array of ridges and grooves generally extending above a planar surface on both the obverse and reverse surfaces of a fill-sheet, which fill-sheets at an assembled state provide the ridges and grooves of facing obverse and reverse surfaces of adjacent fill-sheets in an arrangement providing a plurality of channels between adjacent fill-sheets for gas flow therethrough and where the ordered arrangement of ridges and grooves induces spiraling of the gas flow through the channels for promotion of improved heat transfer; and, where the fill-sheets further include a spacing arrangement providing a compact nesting of adjacent sheets with minimal sheet-to-sheet displacement at least at two of the edges for compact handling, transfer and storage with a self-spacing of adjacent fill-sheets at assembly of the film fill-pack. Fill-packs generally utilize retention louvers at a gas-inlet site to maintain coolant fluid within the fill-pack structure, which disclosed louvers have specific relationships to their angularity, height and length to minimize their volume while maintaining their operational characteristics, and mist eliminators at air discharge locations are operable to minimize gas-entrained coolant discharge to retain the fluid within the cooling apparatus with the control of the angles of mist-eliminator grooves, the structural cross-section of the grooves and the use of microgrooves.

A large anti-vortexing nozzle is provided which may be used in a distribution system comprising multiple nozzles to uniformly distribute fluid to an underlying surface. The nozzle is non-clogging, operates at very low spray pressures, and evenly distributes fluid over a wide area due to its ability to eradicate vortex formations within the nozzle. The nozzle comprises a main body with integrally formed anti-vortexing ears extending upward from the top of the nozzle into the pipe and an underlying dual pyramid shaped deflecting apparatus. In operation, the nozzle produces consistent and continuous, multiple uniform flat planes of fluid because the nozzle now will not sputter, vibrate or induce air because ears on the nozzle eliminate vortex pair formations which are detrimental to nozzle performance.

A large nozzle is provided which may be used in a distribution system comprising multiple nozzles to uniformly distribute fluid to an underlying surface. The nozzle is non-clogging, operates at very low spray pressures, and evenly distributes fluid over a wide area. The nozzle comprises a main body and an underlying dual pyramid shaped deflecting means. In operation, the nozzle produces multiple uniform flat planes of fluid. When used in a distribution system comprising a plurality of nozzles, the planes of fluid from one nozzle intersect with planes of fluid from other nozzles multiple times in all directions about the nozzle to disperse the fluid. The nozzle is also provided with a flow reducing insert means and a flow directing device. A novel method of fastening the large nozzle to the header pipe is also provided.

The vertical height requirement of a cooling tower is reduced by utilizing trapezoidal shaped fill sheets which are suspended generally in line with the entering air stream so as to form a wedge shaped plenum space beneath the lower sloped edges of the fill sheets.

Trapezoidal fill sheet for low silhouette cooling tower

The vertical height requirement of a cooling tower is reduced by utilizing trapezoidal shaped fill sheets which are suspended generally in line with the entering air stream so as to form a wedge shaped plenum space beneath the lower sloped edges of the fill sheets. This enables a method of lengthening the vertical air paths through the media as distance from entry is increased thereby promoting vertical air flow near the entry.
