In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] like Figure 1-3As shown, a water-saving cross-flow heat exchange module described in this embodiment includes a module body 1, and the module body 1 includes a plurality of water flow channels 2 evenly distributed in the front-to-back direction. The water flow channels 2 are open on the upper and lower sides, and the water flow channels 2 include two packing sheets 3. The left and right sides of the two packing sheets 3 are respectively provided with a plug-in structure, and the plug-in structure includes vertical edges 4 symmetrically fixed on the left and right sides of one of the packing sheets 3 in the water flow channel 2 and a slot 5 correspondingly arranged on the other packing sheet 3 in the water flow channel 2. Preferably, the vertical edges 4 and the slot 5 are integrally arranged on the packing sheet 3, and the cross-section of the vertical edges 4 is a "convex" shape, and the cross-section of the slot 5 is a "concave" shape; the heights of the vertical edges 4 and the slot 5 are the same as or less than the height of the packing sheet 3. Specifically, the heights of the vertical edges 4 and the slot 5 are the same as the height of the packing sheet 3 or less than the height of the packing sheet 3. When the heights of the material sheets 3 are the same, the left and right sides of the water flow channel 2 are completely closed, and the airflow cannot enter the water flow channel 2 laterally; when the heights of the vertical edges 4 and the slots 5 are less than the height of the filler sheets 3, part of the airflow can still enter the water flow channel 2, for example, the vertical edges 4 can be arranged in multiple sections along the vertical direction, and the airflow can enter the water flow channel 2 between the vertically adjacent vertical edges 4; an airflow channel 6 is arranged between adjacent water flow channels 2, and the front and rear sides of the airflow channel 6 are both filler sheets constituting the water flow channel 2, and the left and right sides of the airflow channel 6 are open, and a cover plate 7 is arranged on the top surface of the airflow channel 6, and the cross section of the cover plate 7 is U-shaped, and the cover plate 7 is overlapped and buckled on the upper edges of the two filler sheets 3, and the cover plate 7 closes the upper side opening of the airflow channel 6, so that the cooling tower spray water will not flow into the airflow channel 6, and the lower side of the airflow channel 6 is open;

[0020] The left and right sides of the module body 1 are also symmetrically provided with a flow guiding structure 8, on which a plurality of horizontal through holes with a low inner side and a high outer side are evenly distributed, and the through holes are hexagonal, that is, a plurality of honeycomb holes are evenly distributed on the flow guiding structure 8, and the honeycomb holes are connected to the water flow channel 2 and the air flow channel 6. When the air flow contacts the water flow, the through holes with a low inner side and a high outer side can assist in intercepting droplets, thereby further reducing the water flow droplet loss and evaporation loss.

[0021] The working principle of this embodiment is:

[0022] Water is sprayed from the top of the module body 1, and the water flows into the water flow channel 2 from top to bottom. At the same time, all or most of the airflow enters the airflow channel 6 horizontally, and all or most of the inter-wall heat exchange occurs in the module body 1, the water flow temperature decreases, and the airflow temperature increases; in this embodiment, the water flow channel 2 and the airflow channel 6 are assembled by the plug-in structure and the cover plate, and the manual assembly cost and equipment cost are greatly reduced; in addition, the plug-in structure partially or completely closes the left and right sides of the water flow channel 2, reduces or eliminates the airflow passing through the water flow channel 2, forces the airflow to enter the airflow channel 6 more, increases the air cooling air volume, and no water flows into the airflow channel 6, so the airflow and the water flow undergo inter-wall heat exchange, which can reduce or eliminate the amount of evaporated water, inhibit the formation of white smoke at the cooling tower outlet, and achieve the purpose of water saving; compared with the prior art, the present embodiment has a simple structure and low cost, and is suitable for popularization and use.
