1362811 Evaporative heat exchangers BALTIMORE AIRCOIL CO Inc 28 June 1971 [19 May 1971] 30270/71 Heading F4K In a heat exchanger comprising an injector duct. in which air is evaporatively cooled by contact with sprayed water, which subsequently collects in a sump 16, the spray means 15 are located at the air inlet end of the duct to cause a concurrent flow of air through the duct and a plurality of dampers 70 are located adjacent the spray means and are rotatable between a position, Fig. 1, in which they do not divert the spray, and a position such as shown in Fig. 2 in which they quench or divert a proportion of the spray, e.g. towards a wall of the duct hence regulating the flow of air through the duct. Air discharging from the duct may be diverted upwardly by guide vanes 19. The air passes through mist eliminators 18 before discharging from the duct. In use, the cooled water from the sump circulates through a heat load 34 before returning to the heat exchanger.
