[0065] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0066] The packing module 1 includes packing sheets A and B arranged in alternating layers, and the stacked packing sheets A and B form a first flow path R1 and a second flow path R2 within each packing module.

[0067] For ease of explanation, Figure 1 Two adjacent packing modules 1 are labeled as packing module 1a and packing module 1b, respectively. The stacking direction of the packing modules 1 is as follows: Figure 1 In the front-to-back direction, the width direction of filler module 1 is... Figure 1 The left and right directions in the middle.

[0068] Figure 1 The diagram shows a partial upper structure of packing modules 1a and 1b and a schematic diagram of the connection structure between the two packing modules. For clarity, Figure 1 The connection gap between packing module 1a and packing module 1b was enlarged.

[0069] like Figure 1 As shown, on the side perpendicular to the stacking direction (left side of the figure), the upper end of packing sheet A is folded towards the stacking direction (back side of the figure), while the upper end of packing sheet B is folded towards the opposite direction (front side of the figure), thus... Figure 1 In the stacking direction from the front to the rear, the upper left ends of the packing sheets AB are attached to each other, while the upper left ends of the packing sheets BA are open to each other, forming a first upper opening 11. For packing modules 1a and 1b, multiple first upper openings 11 are arranged side by side in the stacking direction. The first upper opening 11 is connected to the first flow path R1 formed between the packing sheets BA.

[0070] The upper end portion of the filler sheet A on the other side of the stacking direction (the right side in the drawing) is folded toward the other side of the stacking direction (the front side in the drawing), and the upper end portion of the filler sheet B is folded toward the opposite side, so that the upper end portions of the filler sheet B-A on the right side are adhered to each other, and the upper end portions of the filler sheet A-B on the right side are open to each other to form a second upper end opening 12 from the front side to the rear side in the stacking direction. A plurality of second upper end openings 12 are arranged side by side in the stacking direction for each of the filler sheets la, lb. The second upper end opening 12 communicates with the second flow path R2 formed between the filler sheet A-B.

[0071] As shown in FIG. 2, the right side edge of the filler sheet A in the width direction of the filler module la, lb is folded toward the other side of the stacking direction (the back side in the drawing) and extended to form a first connecting portion Dl, and the right side edge of the filler sheet B is folded toward the other side of the stacking direction (the front side in the drawing) and extended to form a second connecting portion D2. The first connecting portion Dl of the filler sheet A and the second connecting portion D2 of the filler sheet B can be connected to form a sealed connecting portion D by ultrasonic welding, adhesion or the like. Figure 1

[0072] As a preferred embodiment, a groove and a ridge can be arranged to be fitted into each other on the first connecting portion Dl and the second connecting portion D2, so as to improve the sealing performance of the sealed connecting portion D. For example, a vertical groove can be arranged on the surface of the first connecting portion Dl facing the second connecting portion D2, and a vertical ridge matching the groove can be arranged on the surface of the second connecting portion D2 facing the first connecting portion Dl. Conversely, the groove can be arranged on the second connecting portion D2, and the ridge can be arranged on the first connecting portion Dl.

[0073] Through the folding and the sealed connecting structure, the edge sealing structure of the second flow path R2 is formed between the filler sheet A and the filler sheet B on the right side in the width direction of the filler module la, lb.

[0074] In one of the second flow paths R2, the filler sheet A and the filler sheet B adjacent to each other on both sides of the stacking direction form a filler unit U. Since the first flow path Rl and the second flow path R2 are alternately stacked, in order to form the sealed edge of the first flow path Rl, the top end of the two adjacent filler units U can be connected by adhesion or the like to form a top end connecting edge 13, and the right end of the two adjacent filler units U can be connected by adhesion or the like to form a right end connecting edge 14 on the right side in the width direction of the filler module la, lb.

[0075] In the assembly of the filler module, first, the filler sheet A and the filler sheet B are connected to form a plurality of filler units U by ultrasonic welding. Then, the plurality of filler units U are connected to form the filler module by adhesion or the like. Ultrasonic welding has the advantages of good sealing and strong durability. However, due to the structure, it is difficult to perform ultrasonic welding between the filler units U.​

[0076] In use, the filler modules 1a, 1b are used for heat exchange between cold air and hot water in the cooling tower. At the upper part of the filler modules 1a, 1b, an inlet for hot water is formed at one side in the width direction, and an outlet for air is formed at the other side in the width direction. At the lower part of the filler modules 1a, 1b, an inlet for air is formed at one side or the other side in the width direction, and an outlet for water is formed at the other side or one side in the width direction.

[0077] Taking the first flow path R1 as the air flow path and the second flow path R2 as the flow path for water spraying as an example, hot water is sprayed from the right side second upper end opening 12 of the filler modules 1a, 1b, but if there is a leak at the sealed connection between the filler sheet B and the filler sheet A (the top edge and the edge in the width direction), the hot water will enter the first flow path R1 in which air flows. In particular in winter in the north, the outside air is below zero, which will cause the water that leaks into the first flow path R1 to freeze quickly, block the first flow path R1 and even damage the filler modules 1a, 1b and the cooling tower, causing significant losses.

[0078] When the filler modules are installed in the cooling tower, the above problems will also occur due to leaks at the connecting gap between adjacent filler modules 1a and 1b. In order to form a seal at the connecting surface between the filler modules 1a and 1b, the inventor of the present application has tried various technical means.

[0079] For example, glue is applied at the connecting surface of the filler modules 1a and 1b, but the setting of the glue is affected by factors such as ambient temperature and humidity during on-site construction. In particular in winter, the setting speed of the glue is slow, and leaks are likely to occur.

[0080] For another example, sealing material is filled between the filler modules 1a, 1b, but the sealing material can only form a seal when it is subjected to sufficient extrusion pressure to a certain deformation amount, and the filler sheet is a plastic sheet that is difficult to form sufficient extrusion pressure on the sealing material. If a frame is provided outside the filler modules 1a, 1b, the manufacturing cost of the filler modules and the cooling tower is increased, the wind resistance is increased, and the construction difficulty and the risk of water leakage are still high.

[0081] Based on the above reasons, the sealing between the filler modules in the stacking direction has become a technical problem that is difficult to solve and urgently needs to be solved. The inventor of the present application has conducted in-depth exploration and practice, and finally solved the above technical problem systematically and ingeniously, which will be described in detail below.

[0082]

Fastener 20

[0083] Figure 2 Structure diagram of the fastener 20 of an embodiment of the present application; Figure 3for Figure 2 Side view; Figure 4 This is a structural diagram of the fastener 20 according to another embodiment of the present invention; Figure 5 for Figure 4 Another structural view of the fastener 20 shown; Figure 6 This is a schematic diagram of the installation structure of the fastener 20 on the packing module.

[0084] like Figures 2 to 6 As shown, the fastener 20 includes a side wall 28 and a top wall 22 connected to the top of the side wall 28 and extending to one side, forming a leak-proof space 210 on the lower side of the top wall 22. The top wall 22 is used to cover the end position of the connection gap on the upper side of the packing module 1a and the packing module 1b, while the side wall 28 covers the connection gap between the two modules from one side in the width direction of the packing modules 1a and 1b.

[0085] In some embodiments, the upper surface of the top wall 22 is configured to be inclined. For example... Figure 3 As shown, the left end of the upper surface of the top wall 22 is higher than its right end, allowing water sprayed from above to flow quickly from left to right and preventing it from easily entering the aforementioned leak-proof space 210. Alternatively, the upper surface of the top wall 22 can be configured such that the right end is higher than the left end, allowing water sprayed from above to flow quickly from right to left; or, the upper surface of the top wall 22 can be configured such that the middle is higher and the sides are lower in the left-right direction, both of which can guide water to the corresponding flow path to prevent water from entering the leak-proof space 210.

[0086] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, a fastening portion 25 may also be provided on the lower side of the top wall 22. This fastening portion 25 is used to engage with the second upper opening 12 at the top of the packing modules 1a and 1b, thereby connecting the fastener 20 to the packing modules 1a and 1b. Specifically, part of the fastening portion 25 of the fastener 20 engages with the second upper opening 12 of the packing module 1a, and the remaining part of the fastening portion 25 engages with the second upper opening 12 of the packing module 1b.

[0087] like Figure 2 As shown, in order to reduce wind resistance, a notch 24 is provided on the top wall 22 of the fastener 20 in some embodiments. The shape of the notch 24 is adapted to the shape of the second upper opening 12 in the packing modules 1a and 1b in the width direction edge.

[0088] To prevent water from flowing in through the gap between the lower surface of the top wall 22 and the top edge of the packing modules 1a and 1b, the fastening part 25 of the fastener 20 is configured to fit the shape of the notch 24 and extend downward. That is, when the fastener 20 is fastened at the connection of the packing modules 1a and 1b, the fastening part 25 can be inserted into the second upper opening 12 and seal the gap.

[0089] The length of the aforementioned fastening portion 25 extending downward is configured to gradually increase from the top wall 22 to the side wall 21, forming a lowest point near the top of the side wall 21. This structure facilitates the collection and dripping of water on the surface of the fastening portion 25 at the lowest point onto the inner surface of the packing sheets A and B, thereby improving the heat exchange efficiency between air and water.

[0090] A narrow overlap groove 26 is formed between two adjacent fastening portions 25. This overlap groove 26 fastens to the top connecting edge 13 of the packing sheet B and the packing sheet A. This can be supplemented by applying adhesive or filling with sealant to prevent water leakage from the gap between the top connecting edge 13 and the overlap groove 26. Preferably, a sealing strip 40 can be fastened at the top connecting edge 13. The sealing strip 40 has a roughly U-shaped cross-section and a fastening groove 41 that opens downwards to connect with the top connecting edge 13. Placing the top connecting edge 13 into the fastening groove 41 can waterproof the connection gap between the packing sheets at the top connecting edge 13.

[0091] The cross-sectional shape of the sealing strip 40 can be adapted to the shape of the overlapping groove 26, so that the end of the sealing strip 40 can be embedded into the overlapping groove 26 during installation. The cross-sectional shape of the sealing strip 40 can be either rounded at the top or flat at the top.

[0092] The two sides of the side wall 28 of the fastener 20 in the width direction (i.e. the stacking direction of the packing sheets) are bent toward the side where the top wall 22 is located to form a folded edge 23, so that the side wall 28, the top wall 22 and the folded edge 23 together enclose a leak-proof space 210 to prevent water from entering its interior.

[0093] like Figure 2 As shown, a concave (protruding towards the side of the top wall 22) bent structure 27 is also provided on the side wall 28. When the fastener 20 is fastened to the connection of the packing modules 1a and 1b, the bent structure 27 can engage with the grooves between the packing pieces B and A on the packing modules 1a and 1b, thereby guiding the water in the vertical direction and preventing water from entering the gap between the packing modules 1a and 1b. In addition, the bent structure 27 also improves the strength of the fastener 20.

[0094] like Figure 4As shown, the height of the side wall 21 is adapted to the height of the filler module 1a, 1b, so that the gap between the filler modules 1a, 1b can be prevented from leaking water in the whole height of the filler module 1a, 1b.

[0095] The side wall 21 can be formed as a whole by the same component, or can be formed by multiple components connected together. As shown in Figure 5 As shown, the side wall 21 of the fastener 20 includes a side wall body 211 and an extension 29 located at the lower side of the side wall body 211 and fixedly connected with the side wall body 211. The extension 29 can be connected with the body of the fastener 20 by means of adhesion, welding or the like. The structure of multiple components can reduce the production difficulty and manufacturing cost.

[0096] As shown in Figure 1 At the right edge of the filler module 1a, 1b in the width direction, the sealing connection part D protrudes in the direction away from the filler module 1a, 1b to form a plurality of vertically extending protruding edges.

[0097] As a preferred embodiment, the width of the fastener 20 is adapted to the connection of the filler modules 1a, 1b, and specifically, the sealing connection part D (i.e. the protruding edge of one structure) of at least two filler units U of the filler modules 1a, 1b close to each other are located in the water leakage prevention space 210 of the fastener 20. Thus, the sealing connection part D and the folded edge part 23 of the fastener 20 overlap each other in the width direction of the filler module 1a, 1b to prevent water from splashing or sliding into the inside of the water leakage prevention space 210, and further, the connection gap on the right side of the filler module 1a, 1b in the width direction is closed by the side wall 21 of the fastener 20.

[0098]

Fastener 20'

[0099] To adapt to the change of the structure of the connection of the filler modules 1a and 1b, the utility model further provides a fastener 20' of a deformed structure of the fastener 20.

[0100] As shown in Figure 7 As shown, at the left side of the filler module 1a, 1b in the width direction, the filler sheet B at the back end of the filler module 1a protrudes in the direction of the filler module 1b to form a second protruding part C2 extending along the longitudinal direction; and the filler sheet A at the front end of the filler module 1b protrudes in the direction of the filler module 1a to form a first protruding part C1 corresponding to the second protruding part C2. When the filler module 1a and the filler module 1b are connected, the top end of the first protruding part C1 and the top end of the second protruding part C2 abut to form a protruding sealing part C.

[0101] As shown in Figure 7As shown, multiple vertically extending protruding edges, formed by a combination of packing plates B and A, are formed on the left side of the protruding sealing portion C. These protruding edges are located within the leak-proof space 210.

[0102] On the top left edge of the packing modules 1a and 1b in the width direction, packing pieces A and B in the same packing unit are connected together to form an upper edge sealing part 15.

[0103] like Figure 8 As shown, in order to waterproof the left side structure of the filler modules 1a and 1b, the fastener 20' has a fastening part 25 including two mutually spaced protrusions 251. The two mutually spaced protrusions 251 can be inserted into the first upper opening 11 between two adjacent upper edge sealing parts 15 and engage with the protruding sealing part C to realize the connection between the fastener 20' and the filler modules 1a and 1b.

[0104] In the fastener 20', an overlap groove 26 is also formed between two adjacent sets of fastening parts 25. The width of the overlap groove 26 is adapted to the upper edge sealing part 15 mentioned above so that they can be connected to each other during installation.

[0105] like Figure 9 As shown, the fastener 20' and fastener 20 can be used together, that is, fastener 20 is located at one side of the connection of the packing modules 1a and 1b in the width direction, while fastener 20' is located at the other side of the connection of the packing modules 1a and 1b in the width direction.

[0106] It should be noted that, Figure 1 The protruding edge on the right side of the packing module 1 in the width direction forms a sealing connection part D, while Figure 7 The protruding edge on the left side of the packing module 1 in the width direction is formed as an edge structure composed of packing pieces B and A located on the left side of the protruding sealing part C. However, it is not limited to this. The protruding edge can also be formed as other structures, such as an ear-shaped structure, as long as it can form a hole through the rods 31 and 31'. The hole is preferably a closed through hole so that the fastening assembly 30 or 30' can tighten the packing pieces to prevent slippage.

[0107]

Fastening Component 30

[0108] At the construction site, when the packing module 1 is to be installed inside the cooling tower, in order to achieve a quick connection between the packing modules 1 and speed up the construction progress, the inventor of this utility model has also designed a fastening component 30 that can quickly achieve the connection between the packing modules 1.

[0109] Figure 10 A structural diagram of a fastening assembly 30 according to an embodiment of the present invention is shown; Figure 11 for Figure 10A sectional view of the fastening assembly 30 shown; Figure 12 A schematic view of the fastening assembly 30 of the utility model applied in the connection of the packing modules.

[0110] As Figures 10 to 12 shown, the fastening assembly 30 comprises a rod 31, one end of the rod 31 protrudes outward in the radial direction to form a fixed part 36, and a first fastening surface 37 is formed between the fixed part 36 and the rod 31.

[0111] An axially extending ratchet part 32 is arranged on the outer contour of the rod 31, and the ratchet part 32 is sequentially arranged by a plurality of ratchets along the axial direction of the rod 31.

[0112] The fastening assembly 30 further comprises a fastening cap 33 mounted on the rod 30. The fastening cap 33 has a center hole 43, and a pawl part 34 capable of cooperating with the ratchet part 32 is arranged in the center hole 43. When the fastening cap 33 is connected with the rod 30, the end part 42 of the rod 30 is inserted through the center hole 43 of the fastening cap 33, and the pawl part 34 is engaged with the ratchet part 32. Under the action of the pawl part 34 and the ratchet part 32, the fastening cap 33 can only move towards the fixed part 36, and cannot retreat away from the fixed part 36.

[0113] Based on this, as Figure 12 shown, a through hole part D3 is arranged on the sealing connection part D of the packing modules 1a and 1b, the end part 42 of the rod 30 is inserted through the through hole part D3 of the sealing connection part D of at least two packing units U at the connection of the packing module 1a and the packing module 1b, and the fastening cap 33 is mounted at the ratchet part 32 of the rod 31, so as to tighten the above-mentioned at least two packing units U together.

[0114] Further, in order to realize the detachable connection of the fastening cap 33 and the rod 31, the pawl part 34 and the ratchet part 32 have a separation state when the connecting part 39 is deformed, and a clamping state when the connecting part 39 is reset.

[0115] In some embodiments, the connecting part 39 with a necked structure is arranged at the connection of the pawl part 34 and the fastening cap 33. By arranging the necked structure, the connecting part 39 is easy to deform and reset.

[0116] In some embodiments, an operation part 35 is arranged at the free end of the pawl part 34, and the position of the operation part 35 is suitable for deforming the connecting part 39 under stress. For example, the free end of the pawl part 34 extends in the direction away from the fastening cap 33 to form the operation part 35. For another example, the free end of the pawl part 34 extends in the direction away from the fastening cap 33 and is deflected to the radial outside of the fastening cap 33 to form the operation part 35.

[0117] By pressing the operation part 35 to deform the connecting part 39, the pawl part 34 is disengaged from the ratchet part 32 to separate the fixing cap 33 from the rod 31, so that the fastening assembly can be disassembled and reused.

[0118] In some embodiments, the fixing cap 33 is formed with a second fastening surface 38 on the side facing the fixing part 36, which can be substantially flat, for example, to abut against the surface of the sealing connecting part D to provide clamping force without damaging the sealing connecting part D.

[0119] When assembling the packing modules 1a and 1b on site, the fastening assembly 30 can quickly connect the packing modules 1a and 1b, improving work efficiency and ensuring firm connection.

[0120]

Fastening assembly 30'

[0121] As shown in Figure 13 , the fastening assembly 30' is a variant of the fastening assembly 30, in which the rod 31' is not provided with the fixing part 36 but has the ratchet part 32 and the ratchet part 32'. The rod 31' has oppositely arranged first and second ends, in which the ratchet part 32 allows the fixing cap 33 to move unidirectionally from the first end to the second end (from left to right) and does not act on the fixing cap 33'; while the ratchet part 32' allows the fixing cap 33' to move unidirectionally from the second end to the first end (from right to left) and does not act on the fixing cap 33.

[0122] In some embodiments, as shown in Figure 13 , the ratchet part 32 is located on one side (upper side in the figure) of the outer contour of the rod 31', and the ratchet part 32' is located on the other side (lower side in the figure) of the outer contour of the rod 31'.

[0123] As shown in Figure 14 , a plurality of vertically arranged through-hole parts D3 are provided on the right side of the sealing connecting part D in the width direction of the packing modules 1a and 1b to facilitate the installation of the fastening assembly 30, 30' and the connection of two adjacent packing modules 1a and 1b.

[0124] In addition, as shown in Figure 15 , two through-hole parts D3 are provided on the right side of the sealing connecting part D in the width direction of the packing modules 1a and 1b, so that not only the connection between the packing modules can be achieved, but also the connection between the packing units U inside the packing modules 1a / 1b can be achieved by alternately passing through the fastening assembly 30 / 30' in the up-down direction, i.e. during the assembly of the packing modules, the fastening assembly 30 or the fastening assembly 30' can be used for temporary fixation to facilitate the bonding between the packing units U.

[0125] Note that the through-hole portion D3 can also be formed on the left edge in the width direction of the filler module 1a, 1b.

[0126]

Waterproof system 100

[0127] The waterproof system 100, as a combined system, is used for waterproofing the connecting gap between the filler modules adjacent in the stacking direction. It can include the fastener 20 and / or 20' as described above, and the fastening assembly 30 and / or 30' located at the edge in the width direction of the filler module 1a, 1b. The fastening assembly 30 and / or 30' can be used to achieve the tensioned connection between the adjacent filler modules 1a, 1b, and the fastener 20 and / or 20' is buckled at the edge in the width direction of the filler module 1a, 1b, to waterproof the connecting gap between the filler modules 1a, 1b, thereby greatly improving the construction speed of the filler modules assembled into a filler layer during on-site construction, reducing the impact of the glue on the environment, and the health damage to the construction personnel.

[0128] The waterproof system 100 can further include a sealing strip 40, which is used in combination with the fastener 20 or 20' described above to completely seal the connecting gap between the filler modules 1a, 1b on the upper side and the two sides in the width direction, with good waterproof performance, stability, reliability, and long service life.

[0129] By providing the waterproof system 100, the connecting gap between the filler modules 1a, 1b adjacent in the stacking direction can also form a flow path with the same function as the first and second flow paths in the filler modules 1a, 1b, thereby reasonably utilizing the connecting gap, improving the heat exchange area, and reducing the wind resistance.

[0130]

Waterproof system 200

[0131] The waterproof system 200 is further improved on the basis of the waterproof system 100, and a side panel 50 is added to completely cover the filler module 1 and shield the sealed connecting gap between the filler units U in the filler module 1, so that even if the side end connecting edge 14 between the filler units U leaks, it can also prevent water from leaking into the air flow path.

[0132] The following describes the filler module 1b, Figure 17The diagram shows a schematic of packing modules 1a, 1b, and 1c connected sequentially in the stacking direction. Fastener 20a covers and seals the connection gaps between packing modules 1a and 1b, and fastener 20b covers the connection gaps between packing modules 1b and 1c. Side panel 50 covers the connection gaps between the side packing units U of packing module 1b. Specifically, side panel 50 is connected to fastener 20a at one edge in the stacking direction and to fastener 20b at the other edge in the stacking direction, thus completely covering the side of packing module 1b.

[0133] The side panel 50 includes a cover portion 51 for shielding one side surface of the packing module 1b in the width direction, and a bent portion 52 formed at the top edge of the cover portion 51, which bends towards the side where the packing module 1b is located. When the side panel 50 is mounted on the packing module 1b, the bent portion 52 is located on the upper side of the packing module 1b to cover the gap at the top edge of the packing module 1b. The bent portion 52 has a notch 56 that matches the edge shape of the upper opening of the first flow path or the upper opening of the second flow path in the width direction of the packing module to avoid obstructing the first and second flow paths.

[0134] For the connection between the side panel 50 and the fastener 20a, preferably, the side panel 50 overlaps with the fastener 20a in the stacking direction and is fastened to the underside of the fastener 20a. The edge structure of the side panel 50 is shown in Figure 19. Figure 19 In this design, the edge of the side panel 50 is folded away from the paper surface (i.e., outward) to form a fastening edge 55. In use, this fastening edge 55 is fastened to the underside of the fastener 20a, thereby forming a stable connection between the side panel 50 and the fastener 20a and creating a structure that prevents water inflow. Thus, a watertight connection is formed between the fastener 20a and the side panel 50. The same method can be used to connect the side panel 50 and the fastener 20b, or the fastener 20b can be fastened to the underside of the side panel 50. Alternatively, the side panel 50 and the fastener 20a can be integrated. A folding portion 53 is provided on the main body of the side panel 50, i.e., the cover portion 51. The folding portion 53 is adapted to a vertically extending groove on the side of the filler module 1b. The folding portion 53 protrudes towards the side of the filler module 1b and embeds into the groove on the side of the filler module 1b, thereby improving the structural rigidity of the side panel 50. Furthermore, the aforementioned deflection portion 53 extends vertically and is divided into multiple segments, with a clearance portion 54 formed between adjacent deflection portions 53. The clearance portion 54 provides space for the installation of the fastening components 30 and 30'. At the clearance portion 54, the fastening components 30 / 30' pass through the through-hole portion D3 of each packing sheet to assemble the packing sheets into a packing module.

[0135] Cooling Tower 1000

[0136] like Figure 19 As shown, the bottom layer of the cooling tower 1000 is an air intake layer 101, and multiple air dampers 102 are arranged around the air intake layer 101. Above the air intake layer 101, a packing layer 103 is arranged, which consists of multiple packing modules 1 arranged in a matrix on a horizontal plane. Above the packing layer 103, a spray section 104 is arranged, which sprays hot water to be treated onto each packing module 1 of the packing layer 103. In the area between the spray section 104 and the packing layer 103, a baffle 105 extending along the stacking direction of the packing modules 1 is erected approximately vertically, and multiple space intervals 105a and 105b are formed by the baffle 105 and the top surface of the packing modules 1. Space interval 105a serves as the spray space for spraying hot water, and space interval 105b serves as the air intake space for drawing gas from bottom to top. Spray space 105a and air intake space 105b are alternately arranged in the direction perpendicular to the stacking direction of the matrix formed by the packing modules 1, and each partition 105 is arranged at the junction of the first upper opening 11 and the second upper opening 12 of the packing module 1, thereby separating the first flow path R1 and the second flow path R2 that are connected to the first upper opening 11 and the second upper opening 12.

[0137] Above the spray section 104 is the exhaust layer 106, and above the exhaust layer 106 is the exhaust port 108 equipped with a fan 107. The fan 107 draws air upward, causing cold air to enter the air intake layer 101 from the air damper 102 in the lower layer of the cooling tower 1000. The air then passes upward through the packing modules 1 of the packing layer 103, and passes through the spray space 105a and the air intake space 105b respectively. After further mixing in the exhaust layer 106, the air is discharged upward through the exhaust port 108.

[0138] On the other hand, the hot water to be treated, sprayed from the spray section 104 to each packing module 1 of the packing layer 103, is cooled by each packing module 1 and falls to the bottom of the air intake layer 101. The cooled water is then collected by the collection equipment for recycling in the factory.

[0139] Work Status 1:

[0140] As described above, the cooling tower 1000 is set to winter operating mode. At this time, the hot water to be treated, sprayed from the spray section 104, is confined within the spray space 105a and enters one of the two flow paths of the packing module 1. In this embodiment, since the partition 105 is positioned relative to the packing module 1 at the junction of the first upper opening 11 and the second upper opening 12, the first and second flow paths R1 and R2 adjacent to each other between two adjacent packing modules 1 form water flow paths, while the outer flow paths R1 and R2 are adjacent to the second and first flow paths on both sides, respectively, and thus form air flow paths.

[0141] The dry hot air flowing from the air flow path and the wet hot air flowing from the water flow path are mixed in the exhaust layer 106, and after mixing with the dry hot air, the wet hot air is unsaturated, and after being discharged to the atmosphere through the fan 107 and the exhaust port 108, the unsaturated hot air is gradually cooled and cooled, and the amount of fog formed is greatly reduced.

[0142] In the embodiment, by switching the spraying part 104, the spraying space 105a and the air induction space 105b can be flexibly switched, that is, the spraying space 105a is stopped from being sprayed with hot water, and the air induction space 105b is sprayed with hot water, so that the functions of the spraying space 105a and the air induction space 105b are exchanged, on the one hand, the normal work of the cooling tower 1000 can be ensured, and on the other hand, the flow path R1 or R2 of the filler module 1 connected with the air induction space 105b can be effectively cleaned and maintained, so that the normal operation of the cooling tower 1000 is not affected when the cooling tower 1000 is cleaned and maintained.

[0143] Working state two:

[0144] When in the summer working state, the air induction space 105b can be sprayed with hot water by adjusting the spraying part 104, and the spraying space 105a can be sprayed with hot water, so that the heat exchange efficiency of the cooling tower 1000 can be improved as much as possible without fogging in summer.

[0145] The fastener 20, 20' of the utility model is buckled at the connection of the adjacent filler modules in the stacking direction, which prevents the water sprayed from the spraying space 105a from leaking to the air induction space through the above-mentioned connection gap. The fastener 20, 20' of the utility model is connected to the connection of the above-mentioned filler module by buckling, which is quick and convenient to install, and greatly improves the construction progress compared with the adhesion, filling and sealing material and the like, and has good waterproofness and firmness.

[0146] The fastener, fastening assembly, water leakage prevention system and cooling tower of the preferred embodiment of the utility model are described in detail above, but those skilled in the art can make various modifications, changes, combinations and the like on the basis thereof, and these modifications, changes and combinations all fall within the protection scope of the claims of the present application.
