Technical Field

[0001] This utility model relates to a cooling tower, specifically a water-saving and defogging cooling tower. Background Technology

[0002] Regarding the heat exchange packing material technology for cooling towers, the applicant's prior patent 201910877463.9, filed on July 15, 2019, discloses a packing module that separates the downward hot water flow path and the upward cold air flow path. In this packing module, hot water flows in through an opening of a certain width at the upper end of the packing module, and an opening of another width at the upper end of the packing module allows air to flow through. Manufacturing this packing module requires the use of four types of packing materials A, B, C, and D, and it has proven to have good water-saving and anti-fogging effects.

[0009] The heat exchange section includes a first heat exchange section and a second heat exchange section that are alternately stacked in the stacking direction;

[0010] The first heat exchange section is formed between packing sheet B and packing sheet A and is in the form of a flat cavity; the second heat exchange section is formed between packing sheet A and packing sheet B and is in the form of a flat cavity.

[0018] The upper end of the packing sheet A on one side of the stacking direction is biased towards one side of the stacking direction, and the upper end of the packing sheet B on one side of the stacking direction is biased towards the other side of the stacking direction, so that at this part, the packing sheet A and the packing sheet B adjacent to the packing sheet A on one side of the stacking direction are close to each other, and the packing sheet B adjacent to the packing sheet A on the other side of the stacking direction are open to each other, thus forming the first upper opening.

[0019] The upper end of the packing sheet B on the other side of the stacking direction is offset towards one side of the stacking direction, and the upper end of the packing sheet A on one side of the stacking direction is offset towards the other side of the stacking direction.

[0050] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0051] [First Implementation Method]

[0052] The filling module 1 of the first embodiment of this utility model will be described in detail below.

[0053]

Filling Module 1

[0054] In this embodiment, the packing module 1 includes packing sheets A and B that are alternately stacked at a predetermined interval d. The stacked packing sheets A and B form an alternately arranged first flow path R1 and second flow path R2 within the packing module 1.

[0055] An upper guide section 200 and a heat exchange section 400 are formed in the upper and lower sections of the packing module 1, respectively.

[0056] [Introductory Section 200]

[0057] At the upper end of the upper guide section 200, the upper ends of rectangular packing pieces A and B are alternately arranged to form a guide opening, as detailed below.

[0058] On the side perpendicular to the stacking direction (left side in the figure), the upper end of packing sheet A is offset towards the stacking direction (back side in the figure), while the upper end of packing sheet B is offset towards the opposite direction (front side in the figure). This results in the upper left ends of packing sheets AB fitting together in the stacking direction from front to back, while the upper left ends of packing sheets BA are open to each other, forming a first upper opening 210. For packing module 1, multiple first upper openings 210 are arranged side-by-side in the stacking direction. Thus, the first upper opening 210 communicates with the first flow path R1 formed between the packing sheets BA.

[0059] On the other side perpendicular to the stacking direction (right side in the figure), the upper end of packing sheet A is offset towards the other side of the stacking direction (front side in the figure), while the upper end of packing sheet B is offset towards the opposite side (rear side in the figure). This results in the upper right ends of packing sheets BA fitting together in the stacking direction from front to rear, while the upper right ends of packing sheets AB are open to each other, forming a second upper opening 220. For packing module 1, multiple second upper openings 220 are arranged side-by-side in the stacking direction. Thus, the first upper opening 220 communicates with the first flow path R2 formed between packing sheets AB.

[0060] It should be noted that in this utility model, such as Figure 1 As shown, the stacking direction is the front-to-back direction in the coordinate system; while the direction perpendicular to the stacking direction is understood as the left-to-right direction in the figure, that is, the width direction of the filler module.

[0061] In the upper guide section 200, a left upper path rectifier 230 is embedded in the first flow path R1 between the first upper opening 210 formed by the packing sheet BA and the heat exchange section 400 surrounded by the packing sheet BA. The upper end of the left upper path rectifier 230 matches the width of the first upper opening 210, and the width gradually increases from top to bottom, while the lower end corresponds to the width of the heat exchange section 400 (the first heat exchange section 401 of the first flow path).

[0062] In this embodiment, the left upper rectifier plate 230 has a bent cross-section along the transverse direction perpendicular to the stacking direction. The two sides of the bent stacking direction, i.e., the back side, abut against the front surface of the packing plate A that holds it, and the front side abuts against the rear surface of the packing plate B that holds it. Thus, in the first flow path R1, which is approximately a right-angled trapezoid formed between the first upper opening 210 and the heat exchange section 400, a guide portion is formed that guides the width of the first upper opening 210 to the full width of the heat exchange section 400, which is approximately the width of the packing plates A and B.

[0063] In the upper guide section 200, a right upper path rectifier 240 is embedded in the second flow path R2 between the second upper opening 220 formed by the packing sheet AB and the heat exchange section 400 surrounded by the packing sheet AB. The upper end of the right upper path rectifier 240 matches the width of the second upper opening 220, and the width gradually increases from top to bottom. The lower end corresponds to the width of the heat exchange section 400 (the first heat exchange section 402 of the second flow path).

[0064] In this embodiment, the right upper rectifier plate 240 has a bent cross-section along the transverse direction perpendicular to the stacking direction. The two sides of the bent stacking direction, i.e., the back side, abut against the front surface of the packing plate B that holds it, and the front side abuts against the rear surface of the packing plate A that holds it. Thus, in the second flow path R2, which is approximately a right-angled trapezoid formed between the second upper opening 220 and the heat exchange section 400, a guide portion is formed that guides from the width of the second upper opening 220 to the full width of the heat exchange section 400, which is approximately the width of the packing plates A and B.

[0065] A packing module 1 is formed by alternately stacking packing sheets A and B, and within the packing module 1, a first flow path R1 and a second flow path R2 are formed, which are isolated from each other and alternately stacked. The configuration of the first flow path R1 and the second flow path R2 will be described in detail below.

[0066] [Units of the first flow path R1]

[0067] In this embodiment, for the packing module 1, in the stacking direction from the front to the rear in the figure, the unit that forms the first flow path R1 between the adjacent packing sheet B and the packing sheet A located behind the packing sheet B, i.e., the packing sheet BA.

[0068] As shown in the figure, the first flow path R1 includes, from top to bottom, a first upper opening 210 located on the left side of the upper end of the packing module 1; a left upper guide section 201 located in the upper guide section 200, filled and supported between the packing plates B and A by the left upper rectifier plate 230; a first heat exchange section 401 with a flat cavity formed between the packing plates BA in the stacking direction at the heat exchange section 400; and a first lower opening 310 located at the lower end of the packing module 1, the width of which is approximately the same as the width of the first heat exchange section 401 (perpendicular to the stacking direction).

[0069] Therefore, in this embodiment, a unit of the first flow path R1, which forms a flat cavity, is formed between adjacent packing sheet B and packing sheet A.

[0070] [Units of the second flow path R2]

[0071] In this embodiment, for the packing module 1, in the stacking direction from the front to the rear in the figure, the unit that forms the second flow path R2 between the adjacent packing sheet A and the packing sheet B located behind the packing sheet A, i.e., the packing sheet AB.

[0072] As shown in the figure, the second flow path R2 includes, from top to bottom, a second upper opening 220 located on the right side of the upper end of the packing module 1; a right upper guide section 202 located in the upper guide section 200, filled and supported between packing sheets A and B by the upper right rectifier plate 240; a second heat exchange section 402 formed in a flat cavity between packing sheets A and B in the stacking direction at the heat exchange section 400; and a second lower opening 320 located at the lower end of the packing module 1, the width of which is approximately the same as the width of the second heat exchange section 402 (perpendicular to the stacking direction).

[0073] Therefore, in this embodiment, a unit of a second flow path R2 with a flat cavity is formed between adjacent packing sheet A and packing sheet B.

[0074] Heat Exchanger 400

[0075] The first heat exchange section 401 and the second heat exchange section 402 are alternately stacked to form a heat exchange section 400 in which the first flow path R1 and the second flow path R2 are alternately stacked and exchange heat at intervals.

[0076] [Openings at the top and bottom of the flow path]

[0077] As described above, in the stacking direction of packing sheets A and B, a first flow path R1 and a second flow path R2 are formed between packing sheets BA and AB, respectively, forming flat cavities, thereby alternating the stacking of the first flow path R1 and the second flow path R2. Thus, for packing module 1, first and second upper openings 210 and 220 are formed at the upper edge, perpendicular to the stacking direction.

[0078] In this embodiment, as shown in the figure, the first upper opening 210 is formed on the left side. Since the upper left end of packing sheet A is offset towards the back side in the figure, and the upper left end of packing sheet B is offset towards the front side in the opposite direction in the figure, the upper left ends of packing sheets AB are attached to each other, while the upper left ends of packing sheet BA are open to each other. Thus, the strip-shaped openings with the upper left ends of packing sheets BA open to each other are arranged side by side in the stacking direction through the attached upper left ends of packing sheets AB, forming a complete first upper opening 210. Without considering the thickness of the packing sheets, it is equivalent to forming the entire open first upper opening 210 in the entire area of ​​the upper end of the packing module 1 on the side perpendicular to the stacking direction (left side in the figure).

[0079] Similarly, the second upper opening 220 is formed on the right side. Opposite to the first upper opening 210, the upper right end of packing sheet B is offset towards the back side in the figure, while the upper right end of packing sheet A is offset towards the front side in the opposite direction in the figure. Therefore, the upper right ends of packing sheets BA are attached to each other, while the upper right ends of packing sheets AB are open to each other. This forms a strip-shaped opening with the upper right ends of packing sheets AB open to each other, arranged side-by-side in the stacking direction via the attached upper right ends of packing sheets BA, forming a complete second upper opening 220. Without considering the thickness of the packing sheets, this is equivalent to forming an open second upper opening 220 in the entire area of ​​the upper end of the packing module 1 on the other side (right side in the figure) perpendicular to the stacking direction.

[0080] Furthermore, for the packing module 1, a first lower opening 310 communicating with the first flow path R1 and a second lower opening 320 communicating with the second flow path R2 are formed at the lower edge. In the packing module 1, the first lower opening 310 and the second lower opening 320 are alternately stacked and each occupies the full width of the packing module 1.

[0081] The width of the first lower opening 310 ( Figure 2 The width of the second lower opening 320 is the same as the width of the packing module 1; the width of the second lower opening 320 is the same as the width of the packing module 1. The thickness of the first lower opening (in the left-right direction) is the same as the width of the packing module 1. Figure 2 The opening size in the front-to-back direction is the same as the thickness of the first heat exchange section; the thickness of the second lower opening is the same as the thickness of the second heat exchange section.

[0082] [Opening of the flow path]

[0083] The first flow path R1 will be further described in detail from top to bottom.

[0084] As described above, the first flow path R1 forms a first upper opening 210 at the upper end of the packing module 1, which is equivalent to forming a first upper opening 210 in the entire left area perpendicular to the stacking direction. At the first upper opening 210, the portion where the upper left ends of the packing sheets AB are attached to each other is divided into multiple units. After passing downward through the portion where the upper left ends of the packing sheets AB are attached to each other in the upper left guide section 201, the units of the first flow path R1 separate from each other in the stacking direction. On the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases in the direction perpendicular to the stacking direction to approximately the width of the packing sheets A and B, forming a flat shape, that is, the thickness decreases and the width increases. The units of the first heat exchange section 401 enter the flat heat exchange space defined by the packing sheet BA from the upper guide section 200.

[0085] Therefore, in the first flow path R1, the cross-sectional area of ​​the entire flow path from the first upper opening 210 through the upper guide section 200 and the heat exchange section 400 theoretically remains roughly unchanged.

[0086] The second flow path R2 is rotationally symmetrical to the first flow path R1, which will be explained in more detail below.

[0087] As described above, the second flow path R2 forms a second upper opening 210 at the upper end of the packing module 1, which is equivalent to forming a second upper opening 210 in the entire right-side region perpendicular to the stacking direction. At the second upper opening 210, the portion where the upper right ends of the packing sheets BA are attached to each other is divided into multiple units. After passing downward through the portion where the upper right ends of the packing sheets BA are attached to each other in the upper right guide section 202, the units of the first flow path R1 separate from each other in the stacking direction. On the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases in the direction perpendicular to the stacking direction to approximately the width of the packing sheets A and B, forming a flat shape, that is, the thickness decreases and the width increases. The units of the second heat exchange section 402 enter the flat heat exchange space defined by the packing sheets AB from the upper guide section 200.

[0088] Continuing downwards from the heat exchange section 400 to the second lower end opening 320, which occupies approximately the full width of the packing module 1.

[0089] Therefore, in the second flow path R2, the cross-sectional area of ​​the entire flow path from the second upper opening 220 through the upper guide section 200 and the heat exchange section 400 theoretically remains roughly unchanged.

[0090] As described above, in this embodiment, the sum of the opening areas of the first and second upper openings 210 and 220, which are the upper openings of the first and second flow paths R1 and R2, is consistent with the sum of the cross-sectional areas of the flow paths from top to bottom. Similarly, the sum of the opening areas of the first and second lower openings 310 and 320, which are the lower openings of the first and second flow paths R1 and R2, is consistent with the sum of the cross-sectional areas of the flow paths from top to bottom. That is, the opening areas at the upper and lower ends of the packing module 1 are consistent with the horizontal cross-sectional area of ​​the packing module 1, thereby greatly improving the fluid throughput and efficiency of each flow path R1 and R2 and reducing the resistance of the packing module 1. This will be explained in more detail later.

[0091] Rectifier chip

[0092] Thus, when rectifiers 230 and 240 are embedded in each guide section 201 and 202, that is, when rectifiers 230 and 240 are embedded into their respective first and second flow paths R1 and R2, since each rectifier 230 and 240 is formed in a bent shape, and the extension direction of the bent ridge corresponds to the extension path of the first and second flow paths R1 and R2 respectively, the thickness of each rectifier 230 and 240 is much different from the flow path cross-sectional area of ​​the first and second flow paths R1 and R2, so it will not affect the throughput efficiency of the first and second flow paths R1 and R2.

[0093] Furthermore, in this embodiment, the first upper opening 210 and the second upper opening 220, which are the upper openings of the first and second flow paths R1 and R2, are arranged side by side perpendicular to the stacking direction and have approximately the same width. Thus, the upper left rectifier 230 and the upper right rectifier 240, which are located in the upper left guide section 201 and the upper right guide section 202 respectively, have approximately the same housing space configuration and are arranged in a rotationally symmetrical manner. Therefore, the same components can be used to construct the upper left rectifier 230 and the upper right rectifier 240.

[0094] In this embodiment, the same packing sheet A and packing sheet B as in the first embodiment can be used. In the first embodiment, a left upper rectifier 230 and a right upper rectifier 240 are respectively provided for the upper left guide section 201 and the upper right guide section 202. That is, fluid flowing into / introducing into the packing module 1 from one side (left side) of the width direction of the packing module 1 forms a flow path R1 of approximately the full width of the packing module 1 in the heat exchange section 400; while fluid flowing into / introducing into the packing module 1 from the other side (right side) of the width direction of the packing module 1 forms a flow path R2 of approximately the full width of the packing module 1 in the heat exchange section 400. The thickness of R1 and R2 in the stacking direction is half the thickness of each opening in the stacking direction, and the sum of the thicknesses of R1 and R2 is equivalent to half the thickness of the packing module 1 in the stacking direction. If hot water flows in from the first upper opening 210 on the upper left side, it flows out of the packing module 1 from the first lower opening 310, which occupies approximately the full width of the packing module 1. Cold air introduced from the first lower opening 310 flows out of the packing module 1 from the first upper opening 210 on the upper left side. In the first flow path R1, hot water and cold air exchange heat to form humid hot air. Cold air introduced from the second lower opening 320 exchanges heat with the hot water in the first flow path R1 through the wall to form dry hot air. The humid hot air and dry hot air mix in the upper space of the cooling tower to form unsaturated hot air, which can effectively reduce or eliminate the formation of white mist when discharged into the atmosphere.

[0095] Of course, the packing module 1 can also be made the same as the previous packing module, with hot water being poured into the first and second upper openings 210 and 220 at the same time, while cold air is drawn in from the first and second lower openings 310 and 320 at the same time, so that the hot water and cold air in the flow path can directly contact each other in opposite directions to exchange heat. However, it is not possible to make the first flow path R1 and the second flow path R2 flow into different fluids as mentioned above, so that the discharged hot air after heat exchange has low saturated humidity to avoid fogging.

[0096] [Second Implementation Method]

[0097] The packing module 1', a preferred embodiment of this utility model, differs from the packing module 1 of the first embodiment in that a rectifier is only provided in the first flow path R1, specifically the upper left rectifier 230 located within the upper left guide section 201 of the first flow path R1, while no rectifier is provided in the second flow path R2. Therefore, in this embodiment, the first flow path R1 is used as a water spraying channel, while the second flow path R2 is used as an air intake channel.

[0098] like Figures 10-12As shown, by providing rectifier plates 230 only in the first flow path R1, the spray water flowing into the packing module 1' from the first upper opening 210 (a portion of the width of the upper opening) arranged along the stacking direction to the left of the arrow in the diagram is guided by the rectifier plates 230 to approximately the full width of the first heat exchange section 401 within the upper left guide section 201, effectively forming a water film on the walls of the packing plates A and B on both sides of the first flow path R1. Finally, the water flows out from approximately the full width of the lower opening of the packing module 1' at the first lower opening 310.

[0099] On the other hand, cold air introduced into the packing module 1' via the second lower opening 320 arranged in the stacking direction, i.e., the approximate full width of the lower opening, flows within the approximate full width of the second heat exchange section 402, effectively exchanging heat with the hot water attached to the wall of the first heat exchange section 401 through the packing sheets A and B. Then, in the upper right guide section 202, the width of the flow path is gradually restricted to a portion of the width of the second upper opening 220 arranged in the stacking direction, i.e., the upper opening, and the thickness of the flow path in the stacking direction is gradually increased to 2d, and then led out from the second upper opening of the packing module 1'.

[0100] As can be seen, compared with the packing module 1 of the first embodiment of this utility model, by removing the rectifier plate located in the upper right section guide portion 202 of the second flow path R2 and using the second flow path R2 only as a cold air flow path, the cold air drawn into the second flow path R2 can obtain the lowest possible wind resistance. Furthermore, since air flow is not affected by gravity as water flow, even without rectifier plates, while ensuring the same airflow through the second flow path R2 as in the first embodiment, approximately the same cooling efficiency as the packing module 1 of the first embodiment can be obtained. However, since there are no rectifier plates in the second flow path R2, the wind resistance of the air introduced into the packing module 1' is even lower. When using an active exhaust cooling tower, the power required by the fan at the top of the cooling tower is lower, effectively saving energy. Moreover, since the packing module 1' in this embodiment can obtain lower wind resistance, it is more suitable for cooling towers such as hyperbolic cooling towers that do not have fans and use a passive air intake method.

[0101] Furthermore, in this embodiment, such as Figure 11 As shown, the upper end of the packing sheet A of the packing module 1' is located on the left side of the portion where the first upper opening 210 and the second upper opening 220 connect, i.e., on the side of the first upper opening 210, from the base position O of the heat exchange section 400 of the packing sheet A. AThe rear half of the first upper opening 210, formed by the packing sheet A, is formed by offsetting it backward by a distance d / 2. Furthermore, a portion offset forward by a distance d from the rear half of the first upper opening 210, i.e., from the base position O of the heat exchange section 400 of the packing sheet A, is formed at the left edge of the packing sheet A. A The left sealing edge 215A is formed by offsetting forward by d / 2. The left sealing edge 215A extends in a straight line in the vertical direction.

[0102] Furthermore, at the upper end of the packing sheet A, on the right side of the portion where the first upper opening 210 and the second upper opening 220 connect, i.e. on the side of the second upper opening 220, it is offset forward by a distance d / 2 to form the front half of the second upper opening 210 of the second flow path R2 on the rear side formed by the packing sheet A.

[0103] Furthermore, at the upper end of the packing sheet B adjacent to the packing sheet A in the stacking direction, on the left side of the portion where the first upper opening 210 and the second upper opening 220 connect, i.e., on the side of the first upper opening 210, from the base position O of the heat exchange section 400 of the packing sheet B. B The first upper opening 210, formed by the packing plate B, is formed by offsetting forward by a distance d / 2. Furthermore, a rearward offset distance d is formed at the left edge of the packing plate B from the first upper opening 210, that is, from the base position O of the heat exchange section 400 of the packing plate B. B The left sealing portion 215B is formed at a rearward offset of d / 2. The left sealing portion 215B extends in a straight line in the vertical direction.

[0104] Furthermore, at the upper end of the packing sheet B, on the right side of the portion where the first upper opening 210 and the second upper opening 220 connect, i.e., on the side of the second upper opening 220, it is offset backward by a distance of d / 2 to form the rear half of the second upper opening 210 of the second flow path R2 on the front side formed by the packing sheet B.

[0105] Therefore, when packing sheet A and its adjacent packing sheet B are assembled in contact with each other, the upper edge of the left side portion of packing sheet A and packing sheet B, the rear half of the first upper opening 210 of packing sheet A and the front half of the first upper opening 210 of the adjacent packing sheet B form a complete first upper opening 210, and on the left side of the first upper opening 210, the left sealing edge portion 215A of packing sheet A and the left sealing edge portion 215B of packing sheet B come together from top to bottom.

[0106] Therefore, the first flow path R1, formed by packing sheet A and its adjacent front packing sheet B, has a 2d-thickness inlet, namely the first upper opening 210, and its left sealing edge 215 is formed by the combination of left sealing edge portions 215A and 215B, which are offset from each other and joined together. Its left sealing edge 215 can easily form a sealing structure during joint sealing. When this first flow path R1 is used as a hot water spray flow path, since hot water is sprayed in from the front and rear arranged first upper opening 210 located on the left side of the packing module 1', hot water is less likely to seep out from the left sealing edge 215 when guided into the heat exchange section 400.

[0107] On the other hand, after hot water is guided from the first upper opening 210 to the heat exchange section 400, the water flows along the rear wall of the packing sheet B and the front wall of the packing sheet A within the heat exchange section 400 under its own gravity, and will not easily intrude into the right sealing edge of the packing module 1'. Therefore, the sealing requirements for the right sealing edge are significantly reduced.

[0108] Therefore, in this embodiment, any joining method can be used for the sealing portion 215 formed by the left sealing portions 215A and 215B. However, from the perspective of assembly convenience, it is preferable to join the sealing portion 210 by pressure welding. This is because when assembling the packing sheets A and B and the rectifier plates 230 and 330 using the equipment, simply aligning the adjacent packing sheets B in the front-to-back direction will cause the packing sheets A and B to be offset to each other on the right side of their upper and lower edges. Therefore, in this state, the welding operation of the packing sheet BA can be completed by operating the pressure welding equipment to weld the sealing portion 215 and the right side of the upper and lower edges of the packing sheet BA.

[0109] By inserting rectifier plates 230 between the packing sheets BA and welding the sealing portion 215 and the right side of the upper and lower edges of the packing sheets BA, the packing sheets BA in the stacking direction can form a module with very high structural stability. Then, the modules formed by multiple packing sheets BA are combined and glued together in the stacking direction. Because the individual modules have good strength and stability, the difficulty of module assembly can be greatly reduced, and the efficiency of assembling the packing sheet BA modules into packing module 1' can be improved.

[0110] In the accompanying drawings of this embodiment, for ease of assembly and processing, the right-side sealing edge is not fitted with the same structure as the left-side sealing edge 215. However, this does not constitute a limitation on the construction of the right-side sealing edge; of course, the right-side sealing edge can also be fitted with the same structure as the left-side sealing edge 215.

[0111] [Third Implementation Method]

[0112] As a preferred embodiment of the present invention, the filling module 1”, such as Figure 13 , 14 As shown, the difference from the packing module 1 of the first embodiment is the configuration and assembly method of the upper left rectifier 230, the upper right rectifier 240 and their respective first upper opening 210 and second upper opening 220.

[0113] In this embodiment, the upper edges of the upper left rectifier 230 and the upper right rectifier 240 are respectively lower than the first upper opening 210 and the second upper opening 220, that is, the upper edges of the upper left rectifier 230 and the upper right rectifier 240 are respectively located inside the first upper opening 210 and the second upper opening 220.

[0114] In other words, in this embodiment, the open-side ends of the rectifier segments 230 and 240 are respectively located at a predetermined distance h inside the corresponding upper openings 210 and 220. Figure 13 , 14 The example shown is only the upper left rectifier 230, while rectifier 240 can be configured in the same way.

[0115] When packing sheets A and B are stacked, at the upper left guide section 201, because packing sheet A is offset to the rear side in the stacking direction and packing sheet B is offset to the front side in the stacking direction, the upper left edges of the two are brought together at the edge of the first upper opening 210.

[0116] Because the rectifier 230 embedded in the upper left guide section 201 is located inside the first upper opening 210, it avoids the upper edge of the filler sheet AB in the stacking direction at the first upper opening 210 and maintains a distance of h. Therefore, the avoidance area can be welded using a heating fixture to form a welding trajectory L.

[0117] In the first and second embodiments, the rectifier 230 is not retracted into the first upper opening 210. During welding, due to the interference of the rectifier arranged in a bent manner on the end face of the first upper opening 210, the weld can only adapt to the bending of the rectifier 230, forming an intermittent weld. As for the upper left edge of the filler AB, it can only be sealed by applying glue after being closed.

[0118] In contrast, in this embodiment, by retracting the rectifier plate into the first upper opening 210, the clearance area can be used to perform continuous pressure welding on the upper left edge of the packing sheet AB.

[0119] In this way, the connection strength of the upper left edge of the packing sheet AB is improved, and the overall strength of the packing module 1” can be significantly improved after multiple layers of packing sheets A and B are stacked.

[0120] On the other hand, and more importantly, when the first flow path R1 on the left is used as a hot water spray flow path and the second flow path R2 on the right is used as an air flow path, the inner side of the upper left joint of the packing sheet AB forming the first upper opening 210 is connected to the second flow path R2. By welding this joint, the watertight performance can be effectively improved, and leakage caused by delamination due to aging over the years can be avoided.

[0121] Furthermore, in this embodiment, by making the first lower opening also located on the left side of the packing module 1” as shown in the second embodiment, and forming continuous sealing portions 215A and 215B on the left edges of the packing sheet A and the packing sheet B respectively, the probability of the first flow path R1 leaking to the second flow path R2 at the upper end when it is used as a hot water spray flow path can be minimized; the left side can also be sealed by welding to prevent leakage.

[0122] As for the right side, since the first flow path R1 guides hot water from a portion of the width on the left side to approximately the full width of the heat exchange section, it is difficult for hot water to overflow from the right edge under the influence of gravity. Therefore, the right side sealing edge can be achieved by simple convex-concave jointing, interlocking, bonding, spot welding, or other methods.

[0123] Of course, without considering the slight increase in cost, the right-side sealing edge can be sealed in the same way as the left-side sealing edge. Alternatively, the right-side sealing edge can be formed by offsetting the right edge of the heat exchange section 400 of packing sheets A and B in the same direction as the left edge. This allows for complete sealing of the first flow path R1.

[0124] In this embodiment, as an example, only the configuration of the upper left rectifier 230 and the first upper opening 210 in the upper left guide section 201 is described. The same configuration can also be used for the second upper opening 220 and the corresponding rectifier 240. This improves the overall strength of the packing module 1”, especially the upper surface of the packing module 1” with the parallel upper openings 210 and 220, where the strength will be greatly improved. This significantly improves the robustness, reliability, and durability of the packing module 1” during transportation, handling, installation, and daily operation.

[0125]

Filling Module 1a

[0126] As a preferred embodiment of this utility model, the filling module 1a, such as Figure 19As shown, the only difference between this and the packing module 1 of the first embodiment described above is that in the upper guide section 200, the packing piece A is shaped into a roughly triangular structure with a small top and a large bottom, thus forming an overall roughly pentagonal structure. Correspondingly, the packing piece B also has a roughly triangular structure.

[0127] Cooling Tower 10

[0128] Figure 10 This is a schematic diagram of a cooling tower manufactured based on the packing module 1 of this embodiment.

[0129] The bottom layer of the cooling tower 10 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 generally vertically arranged, and multiple spacers 105a and 105b are enclosed by the baffle 105 and the top surface of the packing modules 1. Spacer 105a serves as the spraying space for hot water, and spacer 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 210 and the second upper opening 220 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 210 and the second upper opening 220.

[0130] Above the spray section 104 is a water collector 110, which effectively intercepts water droplets generated during the cooling process, preventing these droplets from entering the air and thus reducing water loss and environmental pollution. Above the water collector 110 is the exhaust layer 106, and above the exhaust layer 106 is an exhaust vent 108 equipped with a fan 107. The fan 107 draws air upward, causing the cold air to enter the air intake layer 101 from the air damper 102 at the bottom of the cooling tower 10. The air then flows upward through the packing modules 1 of the packing layer 103, passes through the spray space 105a and the air intake space 105b, and is further mixed in the exhaust layer 106 before being discharged upward through the exhaust vent 108.

[0131] 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.

[0132] Work Status 1:

[0133] As described above, the cooling tower 10 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 210 and the second upper opening 220, 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, forming air flow paths.

[0134] In the water flow path, the sprayed water flows into the packing module 1, and through the upper guide section 200, it forms a water film in the heat exchange section 400, which is distributed in a flat space covering approximately the full width of the packing module 1 and adheres to the two side walls of the flat space in the stacking direction. The adjacent flow paths on both sides in the stacking direction serve as air flow paths, and they exchange heat with the hot water in the water flow path through the walls of the packing sheets A and B.

[0135] When the cooling tower 10 operates in winter, the air drawn into the airflow path from below the packing module 1 is dry and cold air with low temperature and low moisture content. During heat exchange with the hot water in the airflow path through the packing module 1, because the heat exchange is completed entirely in independent flow paths separated by packing plates A and B, the air temperature rises when it exits from above the packing module 1, but the moisture content remains unchanged, thus forming hot dry air.

[0136] On the other hand, because hot water is sprayed down from the spray section 104 above in the water flow path, the air drawn in by the fan 107 in the water flow path experiences significant resistance, resulting in a very small airflow relative to the airflow through the air flow path, typically only a fraction of that. The air flowing through the air flow path will form hot saturated air, i.e., humid and hot air.

[0137] Dry, hot air flowing through the airflow path and humid, hot air flowing through the waterflow path mix in the exhaust layer 106. Because there is less humid, hot air is mixed with dry, hot air to form unsaturated hot air. After being discharged into the atmosphere through the fan 107 and the exhaust port 108, the unsaturated hot air is gradually cooled down, resulting in less moisture precipitation and greatly reducing the amount of fog formation.

[0138] In this embodiment, by switching the spray section 104, the spray space 105a and the air intake space 105b can be flexibly switched. That is, hot water is stopped from spraying the spray space 105a, while hot water is sprayed into the air intake space 105b. This allows the functions of the spray space 105a and the air intake space 105b to be switched. On the one hand, this ensures the normal operation of the cooling tower 10, and on the other hand, it allows for effective cleaning and maintenance of the flow path R1 or R2 of the packing module 1 connected to the air intake space 105b. Thus, the normal operation of the cooling tower 10 is not affected when cleaning and maintaining the cooling tower 10.

[0139] Work Status Two:

[0140] When operating in summer, the spray section 104 can be adjusted to spray hot water onto the air intake space 105b and the spray space 105a in the same way, which can ensure that the cooling tower 10 can maximize its heat exchange efficiency without fogging in summer.

[0141] Cooling Tower 20

[0142] In this embodiment, the packing module 1 described above is still used, but as a cooling tower 20, only the differences between it and the cooling tower 10 will be described in detail, and the same configuration will not be described again.

[0143] The cooling tower 20 of this embodiment differs from the cooling tower 10 described above in that, for each spray space 105a, a cover plate 109 is further provided horizontally above the partition 105 along the stacking direction of the packing module 1. Multiple space intervals 205a and 205b are formed by providing the cover plate 109, partition 105, and packing module 1. In this embodiment, the cover plate 109 is only provided in the spray space 205a for spraying hot water, while no cover plate 109 is provided in the exhaust space 205b for exhausting air. Alternatively, cover plates 109 can be provided in both the spray space 105a and the exhaust space 205b. The cover plate 109 can be a continuous plate or a combination of multiple plates, and can be flipped along one or both sides of the partition wall 105 to form a detachable or closable configuration, thereby enabling switching between the spray space 205a and the exhaust space 205b.

[0144] Work Status 1:

[0145] This operating state is particularly suitable for winter in northern my country. In this state, the working process of cooling tower 20 is similar to that of cooling tower 10, except that since a cover plate 109 is provided above the spray space 205a, the spray space 205a will not play the role of air intake in principle. Only hot water flows downward through the flow path R1 or R2 of the packing module corresponding to the spray space 205a. Therefore, in the exhaust layer 106 of cooling tower 20, there is only dry hot air from the air intake space 205b.

[0146] Therefore, only dry hot air is drawn out of the exhaust port 108 by the fan 107 in the cooling tower 20, so that the moisture in the hot air discharged by the cooling tower 20 is reduced as much as possible, thereby further improving the defogging ability of the cooling tower 20 in winter. Furthermore, since only dry hot air is discharged, the amount of water discharged by the cooling tower 20 is also less, which is more conducive to water conservation.

[0147] With both the spray space 205a and the air intake space 205b equipped with openable (hinged, split, or removable) covers 109, by opening the cover above the spray space 205a and closing the cover above the air intake space 205b, and adjusting the spray section 104, the functions of the spray space 205a and the air intake space 205b can be switched in the same way as the cooling tower 10. The flow path R1 or R2 of the packing module 1 corresponding to the original air intake space 205b is cleaned, thus preventing the cooling tower 20 from shutting down.

[0148] Of course, by only opening the cover plate 109, the same working state as the above-mentioned cooling tower 10 can be achieved, and its working efficiency and working results are also roughly the same.

[0149] Work Status Two:

[0150] In summer operation, by removing or opening the cover plate 109 above the spray space 205a, the spray section 104 is adjusted so that hot water is sprayed onto the air intake space 205b in the same way as the spray space 205a, so that the cooling tower 20 achieves the same summer operation state as the cooling tower 10, which improves heat exchange efficiency.

[0151] In the cooling tower 20 of this embodiment, the cover plate 109 provided above the partition spaces 205a and 205b is a flat plate, but it is not limited to this. It can also be a plate that extends from the partition plates 105 on both sides of the packing module 1 in the stacking direction of the partition spaces 205a and 205b towards the middle and overlaps to close the partition spaces 205a and 205b. An upward or downward apex is formed at the overlap. That is, as long as the upper part of the partition spaces 205a and 205b can be closed, there is no limitation on the configuration of the cover plate 109.

[0152] In the above embodiment, the rectifier 230 is disposed in the upper left guide portion 201 between the packing sheets BA in the stacking direction of the packing module 1, where the upper section of the first flow path R1 is formed in the upper left guide portion 201.

[0153] Furthermore, the rectifier 240 is disposed in the upper right guide portion 202 between the packing sheets AB in the stacking direction of the upper section guide portion 200 of the second flow path R2.

[0154] Since the first upper opening 210 and the second upper opening 220 each occupy approximately half the width of the packing module 1, the rectifier 230 is actually embedded in a roughly right-angled trapezoidal region formed by extending from approximately the middle of the upper edge of the packing piece BA, downward along the left edge of the upper guide section 200, then rightward along the lower end line of the side upper guide section 200 to the right edge of the upper guide section 200, and then diagonally upward towards approximately the middle of the upper edge of the packing piece A (B). For the packing piece A, it is offset to the rear in this right-angled trapezoidal region, while for the packing piece B, it is offset to the front. Thus, in the stacking direction, the front packing piece A and the rear packing piece B, i.e., the packing piece AB, are tightly joined together around the periphery of the first upper opening 210. Therefore, the width of the opening in the stacking direction between the front packing piece B and the rear packing piece A, packing piece BA at the first upper opening 210 is 2d. In other words, within the right-angled trapezoidal region, the stacking distance at the first upper opening 210 at the top is approximately 2d, while the stacking distance at the lower end where it connects to the heat exchange section 400 is the interval d between the packing sheets A and B, thus forming the space of the upper left guide section 201.

[0155] The rectifier plate 230 has a folded cross-section in the horizontal direction that extends perpendicular to the stacking direction. The upper part near the first upper opening 210 has a large folding amplitude but a small folding span. As it extends from top to bottom towards the heat exchange section 400, the folding amplitude gradually decreases and the folding span gradually increases to fill the space of the upper left guide section 201. By forming a fold in the horizontal direction with the rectifier plate 230, multiple guide flow paths are formed from the first upper opening 210 to the heat exchange section 400. Each guide flow path is thicker at the upper end in the stacking direction and narrower in the horizontal direction, while it is thinner and wider at the lower end. This effectively and evenly guides the hot water flowing in from the first upper opening 210, which is approximately half the width of the packing module 1, to the heat exchange section 400, which is approximately the full width of the packing module 1. Furthermore, whether it is a single guide flow path or the entire guide flow path, the cross-sectional area change from top to bottom is minimized to reduce fluid resistance. Good throughput can be achieved for both hot water sprayed from above and air drawn in from below.

[0156] The rectifier 240 located in the space of the upper right guide section 202 has the same configuration, except that its position is symmetrical to that of the rectifier 230 around the vertically extending axis.

[0157] Therefore, by making the first and second upper openings 210 and 220 approximately half the width of the packing module 1, the upper left guide section 201 and the upper right guide section 202 can be axially symmetrical. Thus, the rectifiers 230 and 240 can be identical components. This allows the packing module 1 to be manufactured using only three components: packing sheet A, packing sheet B, and a universal rectifier. This not only significantly reduces the mold cost and component production cost of the packing module 1, but also eliminates the need to consider the model differences of each rectifier when assembling the packing sheet A, packing sheet B, and rectifier, making assembly convenient and greatly reducing the overall production cost of the packing module 1.

[0158] According to the above preferred embodiment, by offsetting and attaching the packing sheet A and the packing sheet B to the upper guide section, the first upper opening and the second upper opening are stacked in the stacking direction respectively. Without considering the thickness of the packing sheets A and B, the total size of the openings in the stacking direction is approximately the same as the stacking thickness of the packing module in the stacking direction.

[0159] Figures 17-19 A structural diagram of other rectifier designs is shown.

[0160] like Figure 17 As shown in (a), a rectifier segment can be composed of multiple individual strip structures; as Figure 17 As shown in (b), the rectifier segments can have a convex-concave connection structure. A protruding structure is provided on the upper side of the rectifier segment, while a grooved structure is provided on the lower side. This convex-concave connection structure enables the connection between two adjacent strip structures; as shown in (b). Figure 17 As shown in (c), the strip structure can also have an "I" shaped structure.

[0161] like Figure 18 As shown, the rectifier can also have an integral injection-molded structure, with connectors used to connect multiple plates. Alternatively, the rectifier can be multiple plate-like structures, with symmetrical grooves on adjacent filler plates to embed into these plate-like structures.
