Abstract:
Plume abated cooling tower for cooling an aqueous fluid by means of air, said tower comprising:a) at least one air inlet;b) an air outlet;c) an air-aqueous fluid heat exchanger;d) at least one means for ensuring an airflow between the air inlet and the air outlet, as well as through the heat exchanger;e) a distribution system for distributing the fluid to be cooled on the heat exchanger, andf) a drift eliminator located above the distribution system, said drift eliminator reducing the water loss by drift due to the airflow;wherein the heat exchanger has first vertical channels in which air and the fluid to be cooled counterflow, second horizontal channels in which airflows, and a means for avoiding the passage of the fluid to be cooled into said second channels, said second channels having a heat conductive surface contacting a plurality of first channels,wherein the heat exchanger comprises heat exchanger packs with second channels, each pack being made of several heat conductive plates linked the one to another by fins, so that between at least a first couple of adjacent plates the fins define a series of second channels, while between at least another couple of adjacent plates, the fins define a series of first channels, andwherein the cooling tower comprises means for collecting the air heated in the second channels and for conveying said air above the drift eliminator, said means acting as means for avoiding the passage of the fluid to be cooled into said second channels.
