The heat exchange module 7 comprises a transversely arranged cold air pipe group 8, the cold air pipe group 8 is formed by connecting a group of cold air pipes 9 which are parallel to each other and have a uniform distance therebetween, and two ends of each cold air pipe 9 are respectively connected with an air valve 10 arranged on the tower frame 1, see fig. 2. The two side surfaces of each air-conditioning pipe 9 are composed of heat-conducting plates, the heat-conducting plates are made of anticorrosive metal sheets into corrugated plates 11, the corrugated plates 11 are spliced into units and then assembled into the air-conditioning pipe 9, the corrugation direction of the corrugated plates 11 is transversely distributed relative to the cooling tower, and the corrugations are in circular arc or sine wave shapes. The lower side edge of each cold air pipe 9 is provided with a lower valve plate 12; the upper side of each cold air pipe 9 is provided with an upper valve plate 13 near the two ends, and the middle part is provided with a part which accounts for 40-50% of the length of the whole cold air pipe 9, namely the valve plate 13 is not arranged. The adjusting mechanism, including all the lower valve plates 12, is connected in series with a lower operating rod 14 which can uniformly control the opening or closing of all the lower valve plates 12, and all the upper valve plates 13 are connected in series with an upper operating rod 15 which can uniformly control the opening or closing of all the upper valve plates 13, see fig. 3.
The passage change includes opening the upper valve plate 13 and the lower valve plate 12 while closing the dampers 10 at both ends of each cold air duct 9, or closing the upper valve plate 13 and the lower valve plate 12 while opening the dampers 10 at both ends of each cold air duct 9, see fig. 4, 5, and 6, in which fig. 6 shows that the upper valve plate is not provided in the middle of the cold air duct 9.
