1,126,746. Cooling-towers. FILM COOLING TOWERS (1925) Ltd. and P. D. EDMONDSON. 5 Oct., 1966 [7 Oct., 1965], No. 42658/65. Heading F4K. Water is cooled in a cooling tower 1 firstly by natural draught in packing 4 and then by a forced draught induced through packing 8 by fans 14. As shown, water to be cooled enters the cooling tower 1 by a central pipe 2 and is distributed over an irrigation stack 4, the water being thus cooled by natural draught induced into the cooling tower through the upper part 16 of the air inlet 6. A decking 7, impermeable except for an annular peripheral region 10 divides the air inlet 6 into two parts. Within the peripheral region 10 are means for collecting water which has fallen through the upper irrigation stack 4 and distributing same over the cross-flow packing 8. Four fans (positioned within the casing 14) induce a draught through the lower part 9 of the air inlet 6 thus causing air to flow through the cross-flow packing 8 and up through the fans finally discharging in the main part of the cooling tower 1 augmenting the natural draught flow in this region. The cooled water is collected in a basin 5.
