The cooled water from top of the tower, and a part of which blast of air within the tray vl6 passes through suitable spray is diverted downwardly to pass over conventional heads located behind the cross-member l8 in a cooling coils and be exhausted at a point on the relatively ?ne spray, thus cooling the cooling side of the cooling tower remote from’the side 20 coils 22 and the ?uid contained therein. Much of entrance of the blast of air.’ of this spray or mist is rapidly vaporized in the A further object of my invention is to provide coil shed. However, air from the fan l2 will be a cooling tower having a forced draft which will forced downwardly through the opening 29, and cause air to enter the cooling tower and be di 25 through the coil shed, taking the vapors from the vided to course upwardly through the tower and coil shed out through the opening 6 at a location downwardly through a coil shed below the tower. remote from the cooling tower in intake open This invention relates to an improvement in In the accompanying drawing: . ing 4, so that this vapor cannot be drawn into the tower. ; Water falling from the coils in the cross-section; and I coil 'shed is collected in the base 24 beneath the Fig. 2 is a horizontal cross-section on the line 30 tower.
