Abstract: An apparatus for spraying trickler plates with cooling water, particularly in cooling towers, comprises spray channels 7,8 which are formed to be smoothly continuous and which touch or pass through the upper end sections of the trickler plates 1. The trickler plates are provided in the upper areas with a surface pattern 27 for uniform distribution of the cooling water. The spraying apparatus avoids a spacing between the spray channels and the trickler plates and provides for easy manufacture maintenance, particularly for an easy cleaning of the spray channels 7,8 (FIG. 5).
