[0066] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0067] [First Implementation Method]

[0068] The filling module 1 of the first embodiment of this utility model will be described in detail below.

[0069]

Filling Module 1

[0070] 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.

[0071] 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.

[0072] [Introductory Section 200]

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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).

[0078] In this embodiment, the left upper rectifier plate 230 has a zigzag cross-section perpendicular to the stacking direction. The two sides of the zigzag stacking direction, i.e., the back side, abut against the front surface of the packing plate A holding it, and the front side abuts against the rear surface of the packing plate B holding it. Thus, within the approximately right-angled trapezoidal first flow path R1 formed between the first upper opening 210 and the heat exchange section 400, a guide portion is formed that extends from the width of the first upper opening 210 to the full width of the heat exchange section 400, approximately the width of the packing plates A and B.

[0079] 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).

[0080] In this embodiment, the right upper rectifier plate 240 has a zigzag cross-section perpendicular to the stacking direction. The two sides of the zigzag stacking direction, i.e., the back side, abut against the front surface of the packing plate B holding it, and the front side abuts against the rear surface of the packing plate A holding it. Thus, within the approximately right-angled trapezoidal second flow path R2 formed between the second upper opening 220 and the heat exchange section 400, a guide portion is formed that extends from the width of the second upper opening 220 to approximately the full width of the heat exchange section 400, encompassing the widths of the packing plates A and B.

[0081] 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.

[0082] [Units of the first flow path R1]

[0083] 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.

[0084] 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).

[0085] 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.

[0086] [Units of the second flow path R2]

[0087] 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.

[0088] 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).

[0089] 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.

[0090] Heat Exchanger 400

[0091] 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.

[0092] [Openings at the top and bottom of the flow path]

[0093] 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.

[0094] 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).

[0095] 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.

[0096] 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.

[0097] 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.

[0098] [Opening of the flow path]

[0099] The first flow path R1 will be further described in detail from top to bottom.

[0100] 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.

[0101] 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.

[0102] The second flow path R2 is rotationally symmetrical to the first flow path R1, which will be explained in more detail below.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] Rectifier chip

[0108] 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 tortuous shape, and the extension direction of the tortuous 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] [Second Implementation Method]

[0113] 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.

[0114] like Figures 10-12 As 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.

[0115] 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'.

[0116] 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.

[0117] 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. A The 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.

[0118] 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.

[0119] 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. BThe 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] [Third Implementation Method]

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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 230 arranged in a zigzag pattern on the end face of the first upper opening 210, the weld can only adapt to the zigzag pattern 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141]

Filling Module 1a

[0142] As a preferred embodiment of this utility model, the filling module 1a, such as Figure 19 As 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.

[0143] Cooling Tower 10

[0144] Figure 10 This is a schematic diagram of a cooling tower manufactured based on the packing module 1 of this embodiment.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] Work Status 1:

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] Work Status Two:

[0156] 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.

[0157] Cooling Tower 20

[0158] 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.

[0159] 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.

[0160] Work Status 1:

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] Work Status Two:

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] The rectifier plate 230 has a zigzag cross-section in the horizontal direction, extending perpendicular to the stacking direction. The upper part, near the first upper opening 210, has a large zigzag amplitude but a small zigzag span. As it extends downwards towards the heat exchange section 400, the zigzag amplitude gradually decreases while the zigzag span gradually increases to fill the space of the upper left guide section 201. By creating a zigzag shape 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 the lower end is thinner and wider. This effectively and evenly guides the hot water flowing in from the first upper opening 210 (approximately half the width of the packing module 1) to the heat exchange section 400 (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.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] Figures 17-19 A structural diagram of other rectifier designs is shown.

[0176] 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.

[0177] 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.

[0178] [Fourth Implementation Method]

[0179] Similar to the embodiments described above, a configuration of multiple packing sheets arranged in alternating layers is also employed, and a first flow path and a second flow path are formed between the multiple packing sheets 1000A and 1000B, respectively. That is, as... Figure 21 As shown, in the stacking direction of the packing module from front to back, a first flow path 1000G is formed between packing sheets 1000A-1000B; and a second flow path 1000W is formed between packing sheets 1000B-1000A.

[0180] The difference from the above embodiments lies in the placement of the upper openings of the first flow path 1000G and the second flow path 1000W. In this embodiment, the upper opening G of the first flow path 1000G, which serves as the first upper opening, is located in the middle of the upper left-right direction of the filling module 1000; while the upper opening W of the second flow path 1000W, which serves as the second upper opening, includes an upper opening W1 located to the left of the upper opening G and an upper opening W2 located to the right of the upper opening G. That is, in this embodiment, the second flow path 1000W has two upper openings W, and is arranged such that it sandwiches the upper opening G of the first flow path 1000G.

[0181] In this embodiment, the upper opening G of the first flow path 1000G is connected to the first heat exchange section 401 of the first flow path 1000G via the upper guide section of the first flow path 1000G, thereby guiding the upper opening G located in the middle part in the upper width direction of the packing module 1000 to the first heat exchange section 401 that occupies approximately the full width of the packing module 1000.

[0182] The two upper openings W1 and W2 of the second flow path 1000W are connected to the second heat exchange section 402 of the second flow path 1000W via the upper guide section of the second flow path 1000W. The upper openings W1 and W2 located on both sides of the upper opening G of the first flow path 1000G in the upper width direction of the packing module 1000 are guided to the second heat exchange section 402, which occupies approximately the full width of the packing module 1000.

[0183] Specifically, in the front-to-back direction of the stacked packing sheets shown in the figure, a first flow path 1000G is formed between packing sheet 1000A and packing sheet 1000B; a second flow path 1000W is formed between packing sheet 1000B and packing sheet 1000A. Between the heat exchange section 401 of the first flow path 1000G and the heat exchange section 402 of the second flow path 1000W, the distance between packing sheet 1000A and packing sheet 1000B is approximately uniform, that is, packing sheet 1000A and packing sheet 1000B are arranged approximately parallel to each other at portions of the first heat exchange section 401 and the second heat exchange section 402.

[0184] Furthermore, for packing sheets 1000A and 1000B, an upper guide section 200 of the first and second flow paths 1000G and 1000W is provided on the heat exchange section 400, which includes the first and second heat exchange sections 401 and 402 arranged in a stacked manner.

[0185] In this embodiment, by offsetting the packing sheets 1000B and 1000A in opposite directions at the upper guide portion 200 from the upper opening G toward the first heat exchange portion 401, first offset portions 1100B and 1100A are formed, increasing the distance between them, thereby forming the first upper opening 1100 of the first upper guide portion 200G. Furthermore, due to the formation of the first offset portions 1100A and 1100B at the upper guide portion 200 of the packing sheets 1000A and 1000B, the packing sheets 1000A and 1000B are brought together at that portion.

[0186] On the other hand, by offsetting the packing pieces 1000A and 1000B in opposite directions at the upper guide portion 200 from the upper openings W1 and W2 on both sides of the upper opening G to the second heat exchange portion 402, second offset portions 1200A and 1200B are formed, increasing the distance between them, thereby forming the second upper opening 1200 of the second upper guide portion 200W. Furthermore, due to the formation of the second offset portions 1200B and 1200A at the upper guide portion 200 of the packing pieces 1000B and 1000A, the packing pieces 1000A and 1000B are brought together at that portion.

[0187] In this embodiment, as described above, bias portions are formed on the upper sections of the packing sheets 1000A and 1000B, and a first upper opening 1100 and a second upper opening 1200 are formed on the upper section of the packing module 1000. Furthermore, a first upper opening G and second upper openings W1 and W2 are formed at the upper edges of the first upper opening 1100 and the second upper opening 1200. Consequently, in the first flow path 1000G, the first upper opening G, occupying a portion of the width of the middle part of the packing module 1000, connects to the first heat exchange section 401, occupying approximately the entire width of the packing module 1000; and in the second flow path 1000W, the second upper openings W1 and W2, occupying portions of the width of both sides of the packing module 1000, connect to the second heat exchange section 402, occupying approximately the entire width of the packing module 1000. Therefore, in one unit of the second flow path 1000W formed by packing sheets 1000A-1000B, the second upper openings W1 and W2 of the second flow path 1000W are connected to the common second heat exchange section 402.

[0188] Furthermore, the thickness of the first and second upper openings G, W1, and W2 in the stacking direction of the packing module 1000 is greater than the distance between their respective packing sheets 1000A and 1000B in the stacking direction at the heat exchange section 400.

[0189] In this embodiment, in order to make the fluid in the first flow path 1000G and the second flow path 1000W uniform, rectifiers are also provided in the first and second upper guide sections 200G and 200W, respectively.

[0190] As the first rectifier 1300G in the first flow path 1000G, it is disposed within the first upper guide section 200G between the first upper opening G and the first heat exchange section 401. The first upper guide section 200G serves to connect the first upper opening G to the first heat exchange section 401, which is approximately the full width. Therefore, the first rectifier 1300G disposed within the first upper guide section 200G is formed into an approximately isosceles trapezoid with multiple guide grooves whose width gradually increases from top to bottom.

[0191] Furthermore, the second rectifier 1300W, which is part of the second flow path 1000W, is disposed within the second upper guide section 200W between the second upper openings W1 and W2 and the second heat exchange section 402. The second upper guide section 200W serves to connect the second upper openings W1 and W2 to the second heat exchange section 402, which has approximately its full width. Therefore, the second rectifier 1300W disposed within the second upper guide section 200W is formed into approximately two right-angled trapezoids and has multiple guide grooves whose width gradually increases from top to bottom.

[0192] In this embodiment, as described above, since the front projection of the packing sheets 1000A and 1000B is approximately rectangular, the first upper opening 1100 of the first upper guide portion 200G formed by the first biasing portions 1100B and 1100A is formed as an inverted approximately triangular shape; and the second upper opening 1200 of the second upper guide portion 200W formed by the second biasing portions 1200A and 1200B is formed as an inverted approximately right-angled triangle located at the left and right corners of the upper ends of the packing sheets 1000A and 1000B. At this time, the first upper opening G and the second upper openings W1 and W2 are located at the upper edge of the packing module 1000.

[0193] Therefore, in the first rectifier 1300G and the second rectifier 1300W, at positions corresponding to the first upper opening 1100 and the second upper opening 1200 of the first and second upper section inlet portions 200G and 200W, inverted approximate triangles and inverted approximate right triangles are also formed longitudinal rectifier sections. The function of these longitudinal rectifier sections is to pre-separate the first and second upper section guide portions 200G and 200W of the first and second flow paths 1000G and 1000W, so as to ensure that the fluid flow rate in each guide groove is approximately uniform within the oblique rectifier section below it.

[0194] At the lower end of the packing module 1000, from front to back, a second lower opening 1400W is formed between packing sheets 1000B and 1000A, and a first lower opening 1400G is formed between packing sheets 1000A and 1000B. The first lower opening communicates with the first flow path 1000G of 1400G, and the second lower opening 1400W communicates with the second flow path 1000W. The first lower opening 1400G and the second lower opening 1400W are alternately stacked, each occupying approximately the full width of the packing module 1000.

[0195] Based on the packing module of this embodiment, when constructing a cooling tower, multiple packing modules can be arranged side by side in a generally horizontal direction. The differences from the first to third embodiments will be described in detail below.

[0196] (Example 1)

[0197] In this embodiment, since the first upper opening G of the first flow path 1000G is located in the middle of the width direction of the packing module 1000, and the second upper opening W of the second flow path 1000W is located on both sides of the width direction of the packing module 1000, when the packing modules 1000 are arranged side by side, as... Figure 26 The diagram shown is a schematic representation of an example 1 of the use of the filler module 1000 in this embodiment.

[0198] Unlike the first to third embodiments, in this example, the sealing portion between the partition 2005, which separates the air flow path and the spray water flow path, and the packing module 1000, is located inside the width direction of the packing module, and the situation described above, where the lower end of the partition 105 is located at the junction of the packing modules, is not present.

[0199] Specifically, the partition 2005 extends along the stacking direction, and the lower end of the partition 2005 corresponds to the connection between the first upper opening G and the second upper opening W in the width direction of the packing module 1000.

[0200] This makes it easier to seal between the packing module 1000 and the partition 2005, and separates the spray flow path and the air flow path as thoroughly as possible. As a result, the absolute humidity of the cold air flowing in from below the packing module 1000 remains unchanged after passing through the packing module 1000 and exchanging heat with the hot water in the adjacent flow path, and being discharged above the packing module 1000.

[0201] However, the air discharged above the packing module 1000 after heat exchange exchanges with the hot water in the adjacent flow path, thus becoming dry and hot air. While maintaining absolute humidity, the air temperature increases, and the relative humidity decreases significantly.

[0202] In winter, water is poured in from the second upper openings W1 and W2 on both sides of the width direction of the packing module 1000. Under the guiding effect of the second rectifier plate 1300W, it is evenly distributed into the second heat exchange section 402, which occupies approximately the full width of the packing module 1000. Water then flows down along the stacking direction of the flow path on the surfaces of the packing plates 1000A and 1000B on both sides and flows out from the second lower opening 1400W, forming a sheet-like rain curtain that occupies approximately the full width of the packing module 1000.

[0203] In this application example, no baffle is provided on the lower side of the packing module 1000. Therefore, from the air intake layer at the bottom of the cooling tower 2000, the external cold air needs to pass through the rain zone formed by the rain curtain to enter the packing module 1000, thereby preheating the external air and preventing freezing in case of leakage in the cold aisle at the bottom of the packing module 1000. Furthermore, since the flow guiding structure at the bottom of the packing module 1000 and the baffle on the lower side of the packing module 1000 are removed in the cooling tower 2000 of this application example, the manufacturing cost is significantly reduced.

[0204] As the cold air from outside passes through the rain curtain, its temperature rises and its humidity increases slightly, but only slightly. It then flows into the first flow path 1000G from the first lower opening 1400G. Inside the heat exchange section 400, it exchanges heat with the hot water in the second flow path 1000W and flows out from the first upper opening G, forming hot air with lower humidity. This air exits from the top outlet of the cooling tower 2000, reducing or eliminating the formation of white mist.

[0205] In regions with cold winters, the lower damper of the cooling tower 2000 can be positioned to allow cold air to pass through the rain zone along the direction perpendicular to the rain curtain, ensuring it is adequately heated and preventing icing inside the cooling tower. Alternatively, in warmer climates where temperatures remain above freezing year-round, the damper can be positioned on one side of the cooling tower, allowing cold air to quickly enter the packing module through the sheet-like gaps between the rain curtain sections, reducing wind resistance.

[0206] (Usage Example 2)

[0207] Alternatively, valve plate 2009 can be set to an inactive state (open or not set), becoming as follows: Figure 27 Even so, as shown, the cold air drawn in below the packing module 1000, after being discharged above the packing module, only has a small amount of water vapor mixed with the heat-exchanged cold air above the partition 2005.

[0208] Because the temperature of the cooled air increases after heat exchange while the absolute humidity remains unchanged, the saturation is low. On the other hand, the amount of water from the spray path is limited. Therefore, the air with significantly reduced saturation after heat exchange can be effectively utilized to absorb the water released from the spray section. Except in cases where the temperature is very low in winter, the cooling tower 2100 of this application example 2 can also effectively achieve the defogging effect.

[0209] In the above-described usage examples 1 and 2, the first flow path 1000G is used as the air flow path, and the second flow path 1000W is used as the hot water spray flow path. Therefore, the portion between adjacent packing modules 1000 is confined to the range of the hot water spray flow path. In this case, the first flow path 1000G, as the air flow path, ensures the airtightness between the lower end of the baffle 2005 and the packing module 1000, allowing as much air as possible drawn into the cooling tower 2000 to flow through the first flow path 1000G.

[0210] Regarding the installation of packing modules, gaps are inevitable between them; otherwise, installation would be problematic. According to the packing module 1000 of this embodiment, by placing the first upper opening G in the middle of the width direction of the packing module 1000, and placing the second upper opening W on both sides of the width direction of the packing module 1000, adjacent upper openings of adjacent packing modules 1000 can be the second upper opening W, thus allowing the second upper opening W to be designated as the inlet for hot water spraying. This effectively reduces air leakage from the installation gaps between the packing modules 1000. In the first to third embodiments, gaps between the packing modules 100 will inevitably be present in the airflow path, causing some air to flow directly through these gaps without passing through the packing modules, potentially leading to reduced heat exchange efficiency. Furthermore, if the gaps between the packing modules 100 are too large due to construction errors or mistakes, the airflow through the gaps between the packing modules 100 will increase significantly, making it even more difficult to ensure uniform air resistance throughout the cooling tower. This will inevitably affect the stacking direction of the packing modules in the entire cooling tower and the uniformity of heat exchange efficiency between the packing modules.

[0211] Using the filler module 1000 of this embodiment will properly solve the above problems.

[0212] (Usage Example 3)

[0213] As an example of the use of the packing module 1000 in this embodiment, in addition to having the advantages of the above-described examples 1 and 2, it can further improve the heat exchange efficiency of the cooling tower, significantly reduce the cost of the packing module, and further enhance the ease of installation and maintenance. A detailed description follows.

[0214] In this use case, such as Figure 28 As shown, a cooling tower 3000 is constructed using a packing module 1000. Below, only the differences between the cooling tower 3000 and the aforementioned embodiment will be explained.

[0215] In the cooling tower 3000, unlike the aforementioned, each packing module 1000 is provided with a predetermined installation interval 3999 of 300-600mm, and preferably a sealing plate 3998 is provided on the mounting surface at the interval between the packing modules 1000. If the sealing plate 3998 is not provided, the support beam that serves as the mounting base of the packing module 1000 can be made into a plane with a plane corresponding to the interval of the packing modules 1000.

[0216] In this case, in contrast to the aforementioned usage examples 1 and 2, it is preferable to use the second flow path 1000W of the packing module 1000 as the air flow path and the first flow path 1000G as the spray water flow path.

[0217] In this way, when designing the cooling tower 3000, the packing modules 1000 can be spaced out, and the installation interval 3999 allows personnel to enter during the installation and maintenance of the packing modules 1000, thereby moving and inspecting the status of the packing modules 1000 relative to each other.

[0218] In particular, during the installation of the packing modules 1000, due to the relatively long distance between them in the stacking direction, the packing modules 1000 are typically divided and stacked only to a specified thickness to form units. These units are then arranged in a straight line and close to each other in the stacking direction to form a complete row of packing modules 1000. Therefore, during the installation of the cooling tower 3000, to ensure minimal air and water leakage, it is essential to ensure that all units of the packing modules 1000 are installed in a straight line. However, when there is no installation interval 3999 between the packing modules 1000 in the lateral direction, adjusting the straightness of the units in the longitudinal direction is almost impossible. Precise control of installation accuracy is necessary when installing each unit, thus installation efficiency needs to be improved.

[0219] In this application example, since an installation interval 3999 is provided between the packing modules 1000 in the lateral direction, the operator can easily adjust the units of each packing module 1000 by means of the installation interval 3999 when installing the modules of each packing module 1000 in the stacking direction. Even if a unit is damaged due to some special accident, the damaged unit can be disassembled, and the units in front of and behind it can be easily moved to fill the gap, and a new unit can be added from the stacking end of the packing module 1000 to complete the repair.

[0220] When a sealing plate 3998 is installed in installation interval 3999, it is preferable that the sealing plate 3998 can be removed or erected, thus rendering the sealing plate 3998 ineffective. At this time, since the second flow path 1000W is set as an air flow path, a large amount of air passes through only installation interval 3999. This significantly reduces the cooling efficiency for hot water, which can meet some special needs in factory production.

[0221] (Example 4)

[0222] Figure 29 This is a schematic diagram of usage example 4. In this usage example, similar to usage example 3, a gap is provided between the packing modules 1000 in the lateral direction, but a common packing module F is further filled in the gap.

[0223] As a standard packing module F, it can be any existing packing module. For example, it can be the most widely used packing module F that simply uses multiple packing sheets stacked together, in which case there are no separated flow paths in the packing module F. For the thin-plate heat exchange space formed by adjacent packing sheets in each of the two stacking directions, hot water is poured in from the top opening, and the fan of the cooling tower 4000 is used to draw cold air into the packing module F from the bottom opening, so that the air and hot water come into direct contact for heat exchange.

[0224] As shown above, in this example, it is preferable to use the second flow path 1000W as the hot water spray path and the first flow path 1000G as the air flow path. Thus, in this example, hot water is supplied to both the second flow path 1000W and the packing module F. The hot water flowing into the packing module 1000 through the second upper openings W1 and W2 exchanges heat with the air drawn in from the second lower opening 1400W within the packing module 1000. Furthermore, indirect heat exchange occurs between the hot water and the air drawn in from the first lower opening 1400G within the packing module 1000. Conversely, the hot water sprayed into the packing module F directly contacts the air drawn in from its lower end within the packing module F, resulting in heat exchange.

[0225] On the other hand, due to the setting of the second upper openings W1 and W2, the air resistance in the second flow path 1000W is very large. Therefore, the amount of air discharged upward from the second upper opening W of the packing module 1000 is actually very small, which is much smaller than the amount of air passing through the packing module F.

[0226] Therefore, the low-saturation hot air discharged from the first upper opening G of the packing module 1000, the saturated hot air discharged from the packing module F, and a very small amount of saturated hot air discharged from the second upper opening W1 / W2 of the packing module 1000 are mixed above the packing module. This effectively utilizes unsaturated hot air, reduces the saturation of the mixed air, and greatly improves the heat exchange efficiency of the cooling tower while ensuring sufficient defogging effect.

[0227] According to the packing module 1000 of this embodiment, by providing a first upper opening G in the middle of the width direction at the top, and providing second upper openings W (W1, W2) on both sides of the first upper opening G, the packing module 1000 allows for greater flexibility when constructing cooling towers 2000, 2100, 3000, 4000, etc., and also allows for flexible configuration of air and hot water channels. Especially when using the first flow path 1000G connected by the first upper opening G as the air flow path, the isolation between the air flow path and the hot water spray flow path is more thorough. This minimizes the relative humidity of the air after heat exchange, thereby improving the defogging effect, which is particularly suitable for the winter conditions in northern my country.

[0228] However, the packing module 1000 and the cooling tower having the packing module 1000 provided in this embodiment are not limited to the situation described in this embodiment.

[0229] In this embodiment, the packing module 1000 includes upper section guide portions 200G and 200W located in the upper section and heat exchange portions 401 and 402 below them. Alternatingly stacked first flow path 1000G and second flow path 1000W are formed by alternately overlapping packing sheets 1000A and 1000B. The first flow path 1000G includes a first heat exchange portion 401, and the second flow path 1000W includes a second heat exchange portion 402. The first heat exchange portion 401 and the second heat exchange portion 402 overlap to form a heat exchange portion 400.

[0230] The packing sheet 1000A has a biasing portion 1100A in the middle of the upper guide section, which is biased forward in the stacking direction, and biasing portions 1100B on both sides of the upper guide section, which are biased rearward in the stacking direction. The packing sheet 1000B has a biasing portion 1200A in the middle of the upper guide section, which is biased rearward in the stacking direction, and biasing portions 1200B on both sides of the upper guide section, which are biased forward in the stacking direction.

[0231] Thus, by stacking packing sheet 1000A and packing sheet 1000B, a first upper opening G is formed by the offset portions 1100A and 1100B of packing sheet 1000A and packing sheet 1000B formed in the middle of the upper guide portion. A second upper opening W is formed by the offset portions 1200A and 1200B of packing sheet 1000B and packing sheet 1000A formed on both sides of the upper guide portion.

[0232] In the first flow path 1000G, the first upper opening G is connected to the first heat exchange section 401 of the packing module 1000, which is approximately the full width of the packing module. In the second flow path 1000W, the second upper opening W is connected to the second heat exchange section 402 of the packing module, which is approximately the full width of the packing module.

[0233] In this embodiment, no further lower guide section is provided below the heat exchange section. For the first and second flow paths 1000G and 1000W, an alternating first lower opening 1400G and a second lower opening 1400W are formed at the lower end of the packing module, and the first lower opening 1400G and the second lower opening 1400W occupy approximately the full width of the packing module 1000.

[0234] The rectifier plates 1300G and 1300W are located in the upper guide section of the packing module 1000. In particular, when guiding hot water in, it is necessary to guide the spray hot water from the first upper opening G or the second upper opening W (W1, W2) in the middle of the width direction to the first heat exchange section 401 or the second heat exchange section 402, which is approximately the full width. Therefore, the lower end of the rectifier plate forms a guide groove and gradually flattens out so that the guided fluid is evenly distributed on the heat exchange section surface of the packing plates 1000A and 1000B.

[0235] The preferred embodiments of the packing module and cooling tower of the present invention have been described in detail above. However, those skilled in the art can make various modifications, alterations, and combinations based on this description, and all such modifications, alterations, and combinations fall within the protection scope of the claims of this application.

The width of the first lower opening is the same as the width of the packing module; the width of the second lower opening is the same as the width of the packing module. The thickness of the first lower opening 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. Multiple baffles for separating air flow paths and spray water flow paths are provided above the packing module. The sealing portion between the baffle and the packing module is located inside the width direction of the packing module. The baffle extends along the stacking direction, and the lower end of the baffle corresponds to the connection between the first upper opening and the second upper opening in the width direction of the packing module.

13. A cooling tower, characterized in that, Includes a first packing module and a second packing module arranged at intervals. The second packing module consists of multiple stacked packing sheets, forming only one flow path. The first packing module has alternatingly stacked first and second packing sheets to form alternating first and second flow paths. An upper guide section is provided in the upper section of the first packing module. The upper guide section includes a plurality of first upper openings and second upper openings disposed on the upper surface of the first filler module. The first upper opening is located at the upper middle part of the first packing module, arranged side by side along the stacking direction, and connected to the first flow path; The second upper opening is located on both sides of the first upper opening, arranged side by side along the stacking direction, and communicates with the second flow path; A heat exchange section is provided on the lower side of the upper guide section. The heat exchange section includes a first heat exchange section with a flat cavity formed between the second packing sheet and the first packing sheet, which are alternately stacked in the stacking direction; and a second heat exchange section with a flat cavity formed between the first packing sheet and the second packing sheet. Alternating layers of first lower end opening and second lower end opening are formed at the lower end of the heat exchange section; the first lower end opening is connected to the first flow path, and the second lower end opening is connected to the second flow path. The width of the first lower opening is the same as the width of the first packing module; the width of the second lower opening is the same as the width of the first packing module. The thickness of the first lower opening 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. The first flow path serves as an air flow path, through which air flows in from the first lower opening and out from the first upper opening. The second flow path is the flow path for the spray water. The second packing module is adjacent to the second upper opening and the second lower opening of the second flow path, serving as the flow path for spray water, where air flowing in from below exchanges heat with water sprayed from above.
