Abstract: A hybrid cooler with selectively applied water to one or more heat exchangers has one or more water feed channels above each heat exchanger to which water is to be applied constructed to provide a smooth film of water by a feed channel overflow edge and with means for suppression of waves, if any, in the channel.
Abstract: Hybrid dry cooler heat exchangers with one or more tube-fin heat exchange assemblies including at lease one such assembly wetted by water dropped on it with the first of such assembly stamped to provide arrays of slit/louver combinations breaking up water droplets and averting flight of droplets into a gas flowing between adjacent fins.
