Abstract:
1. A method of spreading water in an evaporative cooler, comprising: a) feeding a water stream to a water spreader arrangement; b) dividing said water stream into a pair of partial streams by flowing said water streams over a first substantially vertical projection projecting from a substantially horizontal surface at a first level to divide the stream into partials streams having a predetermined ratio of flow rates as the stream impinges on the first projection; c) dividing each of the two partial streams into two further streams by flowing each partial stream over an associated one of a pair of further projections at a second level below the first; and d) said arrangement providing a water entry point upstream of the first vertical projection, the first level being a substantially horizontal surface, the further projections are substantially horizontal, and the second level is a substantially vertical surface.
