The first flow passage 11 and the second flow passage 12 are variable cross-section passages, and the first flow passage 11 and the second flow passage 12 are periodically changed along the length direction thereof. The first flow channel 11 is a gas flow channel, the cold air flows horizontally along the first flow channel 11, that is, in a cross-flow air intake mode, the second flow channel 12 is a hot water flow channel, the hot water enters the second flow channel 12 and flows down along the second flow channel 12 from top to bottom to form a water drop or water film, and the water temperature is reduced by utilizing the evaporation of the water in the second flow channel 12 and the sufficient heat exchange between the cold air and the hot water. Compared with a counter-flow air inlet mode, the cross-flow air inlet mode has the advantages that the fan is located above the filler and is closer to the outlet, so that the floating water amount is larger, water mist is easily formed around the cooling tower, and the fans are located on two sides of the filler, so that the floating water amount is remarkably reduced, and a good mist elimination effect is achieved.

As shown in fig. 1, the first connection portion 2 further includes a step-shaped connection surface 22, and the step-shaped connection surface 22 can enhance the overall strength of the first connection portion 2 and ensure a firm connection between the packing sheets 1. The connecting surface 22 has at least one guiding surface 221, and the guiding surface 221 is inclined downward, and in this embodiment, two guiding surfaces 221 are provided to perform double buffering and guiding functions on the hot water sprayed from the upper portion, so that the hot water can smoothly flow into the second flow channel 12.

After the adjacent packing sheets 1 are assembled, the two second grooves 14 separate the two adjacent packing sheets 1 to form a plurality of second flow passages 12, and the two second protrusions 15 separate the two adjacent packing sheets 1 to form a plurality of first flow passages 11. Because the edges of the second groove 14 and the second protrusion 15 are periodically changed, the two sides of the first flow channel 11 and the second flow channel 12 formed after the packing pieces 1 are spliced in the length direction are periodically changed in a variable cross section manner.
