Abstract

1,126,737. Cooling towers. BALTIMORE AIRCOIL CO., Inc. 11 Jan., 1966 [15 Jan., 1965], No. 1281/66. Heading F4K. [Also in Division G3] An evaporative heat exchanger has a chamber (10, Fig. 1, not shown) with a group of troughs (11) and a sump (12), each trough having V-notches 13, Fig. 3, in its side walls those in one wall being offset relative to the notches in the other wall. Water spilling from the notches passes heat-exchanger tubes (14) in droplet form and is collected in the sump (12) from which it is recirculated by a pump (15) to the troughs (11). Make-up water enters the sump via a float valve (18), and a fan (20) pumps air through the chamber 10 to atmosphere after passing the heat-exchanger, troughs and mist eliminators (22). Water from the pump (15) is fed centrally into chamber 23 from which it passes by a number of spaced holes 28 into a surrounding reservoir 25 that is open to each trough via openings 29; a stable water level obtains in the reservoir. The water spilling from the notches adheres to the exterior of the trough and the shape of the bottom surface thereof determines the direction in which the droplets fall from the lowermost point of each trough; the two notches in each trough each producing separate and opposed streams of droplets. In a modification, as applied to a cooling tower the heat exchanger tubes are replaced by corrugated plates and the water to be cooled is fed into the troughs.
