[0064] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0065] [First embodiment]

[0066] The filler module 1 according to the first embodiment of the present invention will be described in detail below.

[0067]

Packing module 1

[0068] In this embodiment, the packing module 1 includes packing sheets A and packing sheets B alternately stacked at a predetermined interval d. The stacked packing sheets A and B form alternately arranged first flow paths R1 and second flow paths R2 in the packing module 1 .

[0069] An upper guide portion 200 and a lower guide portion 300 are formed in the upper and lower sections of the filler module 1 , respectively, and a heat exchange portion 400 is formed in the middle section.

[0070] [Upper guide 200]

[0071] At the upper end of the upper guide portion 200 , a guide opening is formed by alternating upper end portions of rectangular filler pieces A and B, as described below.

[0072] On the side perpendicular to the stacking direction (the left side in the figure), the upper end of packing sheet A is offset toward one side in the stacking direction (the back side in the figure), while the upper end of packing sheet B is offset toward the opposite side (the front side in the figure). As a result, in the stacking direction from the front side to the back side in the figure, the upper left ends of packing sheets AB are abutted against each other, while the upper left ends of packing sheets BA are open to form first upper end openings 210. For packing module 1, multiple first upper end openings 210 are arranged side by side in the stacking direction. As a result, the first upper end openings 210 communicate with the first flow path R1 formed between the packing sheets BA.

[0073] On the other side perpendicular to the stacking direction (the right side in the figure), the upper end of packing sheet A is offset toward the other side (the front side in the figure), while the upper end of packing sheet B is offset toward the opposite side (the rear side in the figure). As a result, in the stacking direction from the front side to the rear side in the figure, the right upper ends of packing sheets BA are abutted against each other, while the right upper ends of packing sheets AB are open to form second upper end openings 220. For packing module 1, multiple second upper end openings 220 are arranged side by side in the stacking direction. Thus, the first upper end opening 220 communicates with the first flow path R2 formed between packing sheets AB.

[0074] In the upper guide section 200, a left upper path straightening piece 230 is embedded in the first flow path R1 between the first upper end 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 straightening piece 230 matches the width of the first upper end opening 210, 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 401 of the first flow path).

[0075] In this embodiment, the left upper flow straightening piece 230 has a zigzag cross-section perpendicular to the stacking direction. The two sides of the zigzag in the stacking direction, namely, the back side, abuts against the front surface of the packing sheet A that holds it, and the front side abuts against the rear surface of the packing sheet B that holds it. Consequently, within the approximately right-angled trapezoidal first flow path R1 formed between the first upper end opening 210 and the heat exchange section 400, a guide portion is formed that extends from the width of the first upper end opening 210 to approximately the full width of the heat exchange section 400, extending across the width of the packing sheets A and B.

[0076] In the upper guide portion 200, a right upper path straightening piece 240 is embedded in the second flow path R2 between the second upper end opening 220 formed by the packing pieces AB and the heat exchange portion 400 surrounded by the packing pieces AB. The upper end of the right upper path straightening piece 240 matches the width of the second upper end opening 220, and the width gradually increases from top to bottom. The lower end corresponds to the width of the heat exchange portion 400 (the first heat exchange portion 402 of the second flow path).

[0077] In this embodiment, the right upper flow straightening piece 240 has a zigzag cross-section perpendicular to the stacking direction. The two sides of the zigzag in the stacking direction, namely, the back side, abuts the front surface of the packing sheet B that holds it, and the front side abuts the rear surface of the packing sheet A that holds it. Consequently, within the second flow path R2, which is approximately a right-angled trapezoid formed between the second upper end opening 220 and the heat exchange section 400, a guide portion is formed, extending from the width of the second upper end opening 220 to approximately the full width of the heat exchange section 400, the width of the packing sheets A and B.

[0078] [Lower guide section 300]

[0079] At the lower end of the lower guide portion 300 , a guide opening is formed by alternately arranging the lower ends of the filler sheets A and B, as described below.

[0080] On the side perpendicular to the stacking direction (the left side in the figure), the lower end of packing sheet A is offset toward one side in the stacking direction (the back side in the figure), while the lower end of packing sheet B is offset toward the opposite side (the front side in the figure). As a result, in the stacking direction from the front side to the back side in the figure, the left lower ends of packing sheets AB are in contact with each other, while the left lower ends of packing sheets BA are open to form a first lower end opening 310. Thus, this first lower end opening 310 communicates with the first flow path R1 formed between the packing sheets BA.

[0081] On one side perpendicular to the stacking direction (the right side in the figure), the lower end of packing sheet A is offset toward the other side in the stacking direction (the front side in the figure), while the lower end of packing sheet B is offset toward the opposite side (the rear side in the figure). As a result, in the stacking direction from the front side to the rear side in the figure, the left lower ends of packing sheets BA are in contact with each other, while the left lower ends of packing sheets AB are open to form a second lower end opening 320. Thus, this first lower end opening 320 communicates with the first flow path R2 formed between packing sheets AB.

[0082] In the lower guide section 300, a left lower flow straightening piece 330 is embedded in the first flow path R1 between the first lower opening 310 formed by the packing sheet BA and the heat exchange section 400 surrounded by the packing sheet BA. The lower end of the left lower flow straightening piece 330 matches the width of the first lower opening 310, and the width gradually increases from bottom to top, with the upper end corresponding to the width of the heat exchange section 400.

[0083] In this embodiment, the left lower flow straightener 330 has a zigzag cross-section perpendicular to the stacking direction, with the back side of the zigzag abutting the front surface of filler sheet A, and the front side abutting the rear surface of filler sheet B. Consequently, within the first flow path R1, which is approximately an inverted right-angled trapezoid formed between the first lower end opening 310 and the heat exchange section 400, a guide portion is formed, extending from the width of the first lower end opening 310 to approximately the full width of the heat exchange section 400, the width of the filler sheets A and B.

[0084] In the lower guide section 300, a right lower flow straightening piece 340 is embedded in the second flow path R2 between the second lower opening 320 formed by the packing pieces AB and the heat exchange section 400 surrounded by the packing pieces AB. The lower end of the right lower flow straightening piece 340 matches the width of the second lower opening 320, and the width gradually increases from top to bottom, with the lower end corresponding to the width of the heat exchange section 400.

[0085] In this embodiment, the right lower flow straightener 340 has a zigzag cross-section perpendicular to the stacking direction, with the back side of the zigzag abutting the front surface of filler sheet B, and the front side abutting the rear surface of filler sheet A. Consequently, within the second flow path R2, which is approximately an inverted right-angled trapezoid formed between the second lower end opening 320 and the heat exchange section 400, a guide portion is formed that extends from the width of the second lower end opening 320 to the full width of the heat exchange section 400, roughly the width of the filler sheets A and B.

[0086] The packing module 1 is formed by alternately stacking the packing sheets A and B, thereby forming first and second flow paths R1 and R2 that are isolated from each other and alternately stacked within the packing module 1. The configuration of the first and second flow paths R1 and R2 will be described in detail below.

[0087] [Unit of the first flow path R1]

[0088] In this embodiment, in the packing module 1 , in the stacking direction from the front to the rear in the figure, adjacent packing sheets B and the packing sheet A located behind the packing sheet B, that is, the packing sheet BA, form a unit of the first flow path R1 .

[0089] As shown in the figure, the first flow path R1 includes, from top to bottom, a first upper end opening 210 located on the left side of the upper end of the filling module 1; a left upper section guide portion 201 located between the filling pieces B and A and filled by the left upper path straightening piece 230; a first heat exchange portion 401 in the form of a flat cavity formed between the filling pieces BA in the stacking direction at the heat exchange portion 400; a left lower section guide portion 301 located between the filling pieces B and A and filled by the left lower path straightening piece 330; and a first lower end opening 310 located on the left side of the lower end of the filling module 1.

[0090] Thus, in this embodiment, a unit of the first flow path R1 which is a flat cavity is formed between adjacent filler sheets B and filler sheets A, and the first upper end opening 210 which is the upper end opening and the first lower end opening 310 which is the lower end opening are located on the same side perpendicular to the stacking direction.

[0091] [Unit of the second flow path R2]

[0092] In this embodiment, for the packing module 1, in the stacking direction from the front to the rear in the figure, adjacent packing sheets A and packing sheets B located behind the packing sheets A, that is, packing sheets AB form a unit of the second flow path R2.

[0093] As shown in the figure, the second flow path R2 includes, from top to bottom, a second upper end opening 220 located on the right side of the upper end of the filling module 1; the right upper section guide portion 202 located between the filling sheets A and B and filled by the right upper path straightening piece 240 and supported; the second heat exchange portion 402 which is a flat cavity formed between the filling sheets AB in the stacking direction at the heat exchange portion 400; the right lower section guide portion 302 located between the lower section guide portion 300 and filled by the right lower path straightening piece 340 and supported; and the second lower end opening 320 located on the right side of the lower end of the filling module 1.

[0094] Thus, in this embodiment, a unit of the first flow path R1 is formed as a flat cavity between adjacent filler sheets A and filler sheets B, and the second upper end opening 220 as its upper end opening and the second lower end opening 320 as its lower end opening are located on the same side perpendicular to the stacking direction.

[0095] [Heat exchange unit 400]

[0096] The first heat exchange parts 401 and the second heat exchange parts 402 are alternately stacked to form a heat exchange part 400 in which the first flow paths R1 and the second flow paths R2 are alternately stacked to perform intermittent heat exchange.

[0097] [Upper and lower openings of the flow path]

[0098] As described above, in the stacking direction of packing sheets A and B, first flow paths R1 and second flow paths R2, which are flat cavities, are formed between packing sheets BA and AB, respectively. Thus, first flow paths R1 and second flow paths R2 are alternately stacked. Consequently, packing module 1 has first and second upper end openings 210 and 220 formed at its upper edge, aligned perpendicular to the stacking direction.

[0099] In this embodiment, as shown in the figure, the first upper end opening 210 is formed on the left side. Since the left upper end of filler sheet A is offset toward the back side in the figure, while the left upper end of filler sheet B is offset toward the front side in the opposite figure, the left upper ends of filler sheets AB are affixed to each other, while the left upper ends of filler sheets BA are open to each other. As a result, the strip-shaped openings with the left upper ends of filler sheets BA open to each other are arranged side by side in the stacking direction through the left upper ends of the affixed filler sheets AB, forming a complete first upper end opening 210. Without considering the thickness of the filler sheets, this is equivalent to forming an open first upper end opening 210 on the entire area of ​​the upper end of the filler module 1 perpendicular to the stacking direction (the left side in the figure).

[0100] Similarly, second upper end opening 220 is formed on the right side. Opposite to first upper end opening 210, the right upper end of packing sheet B is offset toward the back side in the figure, while the right upper end of packing sheet A is offset toward the front side in the opposite figure. Consequently, the right upper ends of packing sheets BA are bonded together, while the right upper ends of packing sheets AB are open. This creates a strip-shaped opening with the right upper ends of packing sheets AB open to each other, arranged side by side in the stacking direction via the bonded right upper ends of packing sheet BA, forming a complete second upper end opening 220. Without considering the thickness of the packing sheets, this is equivalent to forming an open second upper end opening 220 across the entire area of ​​the other side of the upper end of packing module 1 perpendicular to the stacking direction (the right side in the figure).

[0101] On the other hand, first and second upper end openings 210 and 220 are formed on the lower end edge and arranged side by side in a direction perpendicular to the stacking direction.

[0102] In this embodiment, as shown in the figure, the first lower end opening 310 is formed on the left side. Because the left lower end of filler sheet A is offset toward the back side in the figure, while the left lower end of filler sheet B is offset toward the front side in the opposite figure, the left lower ends of filler sheets AB are affixed to each other, while the left lower ends of filler sheets BA are open to each other. As a result, the strip-shaped openings with the left lower ends of filler sheets BA open to each other are arranged side by side in the stacking direction through the affixed left lower ends of filler sheets AB, forming a complete first lower end opening 310. Without considering the thickness of the filler sheets, this is equivalent to forming an open first lower end opening 310 across the entire area of ​​the lower end of filler module 1 perpendicular to the stacking direction (the left side in the figure).

[0103] Similarly, second lower opening 320 is formed on the right side. Opposite to first lower opening 310, the right lower end of packing sheet B is offset toward the back side in the figure, while the right lower end of packing sheet A is offset toward the front side in the opposite figure. Consequently, the right lower ends of packing sheets BA are bonded together, while the right lower ends of packing sheets AB are open. This creates a strip-shaped opening with the right lower ends of packing sheets AB open to each other. This is formed by juxtaposing the right lower ends of the bonded packing sheets BA in the stacking direction, forming a complete second lower opening 320. Regardless of packing sheet thickness, this effectively forms an open second lower opening 320 across the entire area of ​​the lower end of packing module 1, perpendicular to the stacking direction (the right side in the figure).

[0104] [Opening of flow path]

[0105] The first flow path R1 will be described in further detail from top to bottom.

[0106] As described above, first flow path R1 forms a first upper opening 210 at the upper end of packing module 1, corresponding to the entire left side region perpendicular to the stacking direction. At first upper opening 210, the cells are divided into multiple units by the portion where the left upper ends of packing sheets AB meet. In the upper left guide section 201, after passing downward through the portion where the left upper ends of packing sheets AB meet, the units of first flow path R1 separate from each other in the stacking direction. On the one hand, their dimensions gradually decrease in the stacking direction, while on the other hand, their dimensions gradually increase perpendicular to the stacking direction to approximately the width of packing sheets A and B, forming a flat shape. That is, their thickness decreases and their width increases. These units then enter the flat heat exchange space defined by packing sheets BA in the heat exchange section 400 from the upper guide section 200.

[0107] When continuing downward from the heat exchange section 400 to the lower guide section 300, in contrast to the situation in the upper guide section 200, the unit of the first flow path R1 moves downward from a flat shape roughly the width of the fillers A and B, and on the one hand, gradually increases in size in the stacking direction, and on the other hand, gradually decreases in size perpendicular to the stacking direction to the width of the second lower end opening 220, that is, the thickness increases and the width decreases, and in the lower left guide section 301, the left lower end portions of the fillers AB are joined to each other and reach the first lower end opening 310.

[0108] Therefore, in the first flow path R1 , the flow path cross-sectional area of ​​the entire flow path from the first upper end opening 210 through the upper guide portion 200 , the heat exchange portion 400 , the lower guide portion 300 to the first lower end opening 310 theoretically remains substantially unchanged.

[0109] The second flow path R2 has a rotationally symmetrical structure with the first flow path R1, which will be described in detail below.

[0110] As described above, the second flow path R2 forms a second upper end opening 210 at the upper end of the packing module 1, which is equivalent to forming a second upper end opening 210 in the entire right side area perpendicular to the stacking direction. At the second upper end opening 210, the portion where the right upper ends of the packing sheets BA are bonded together is divided into multiple units. In the right upper section guide 202, after passing downward through the portion where the right upper ends of the packing sheets BA are bonded together, the units of the first flow path R1 separate from each other in the stacking direction. On the one hand, their size gradually decreases in the stacking direction, and on the other hand, their size gradually increases 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 then enter the flat heat exchange space defined by the packing sheets AB in the heat exchange section 400 from the upper section guide 200.

[0111] When continuing downward from the heat exchange section 400 to the lower guide section 300, in contrast to the situation in the upper guide section 200, the unit of the second flow path R2 moves downward from a flat shape roughly the width of the fillers A and B, and on the one hand, gradually increases in size in the stacking direction, and on the other hand, gradually decreases in size perpendicular to the stacking direction to the width of the second lower end opening 220, that is, the thickness increases and the width decreases, and in the right lower guide section 302, the right lower end portions of the fillers BA are joined together to reach the second lower end opening 320.

[0112] Therefore, in the second flow path R2 , the flow path cross-sectional area of ​​the entire flow path from the second upper end opening 220 through the upper guide portion 200 , the heat exchange portion 400 , the lower guide portion 300 to the second lower end opening 320 theoretically remains substantially unchanged.

[0113] As described above, in this embodiment, the total opening area of ​​the first and second upper openings 210 and 220, which serve as the upper openings of the first and second flow paths R1 and R2, is consistent with the total cross-sectional area of ​​the flow paths from top to bottom. Similarly, the total opening area of ​​the first and second lower openings 310 and 320, which serve as the lower openings of the first and second flow paths R1 and R2, is consistent with the total cross-sectional area of ​​the flow paths from top to bottom. In other words, the opening areas at the top and bottom of the packing module 1 are consistent with the horizontal cross-sectional area of ​​the packing module 1. This significantly increases the fluid throughput and efficiency of each flow path R1 and R2, and reduces the resistance of the packing module 1. This will be further described in detail later.

[0114]

Rectifier

[0115] In this way, when the straightening pieces 230, 240, 330, 340 are embedded in each guide part 201, 202, 301, 302, that is, when the straightening pieces 230, 240, 330, 340 are embedded in their respective first and second flow paths R1, R2, since each straightening piece 230, 240, 330, 340 is formed in a flexural shape, and the extension direction of the flexural protrusion corresponds to the extension path of the first and second flow paths R1, R2, the thickness of each straightening piece 230, 240, 330, 340 is very different from the flow path cross-sectional area of ​​the first and second flow paths R1, R2, and therefore will not affect the passing efficiency of the first and second flow paths R1, R2.

[0116] In addition, in this embodiment, the first upper end opening 210 and the second upper end opening 220, which are the upper end 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. Therefore, the left upper road straightening piece 230 and the right upper road straightening piece 240, which are respectively located in the left upper section guide part 201 and the right upper section guide part 202, have approximately the same structure of their accommodation spaces and are arranged in a rotationally symmetrical manner. Therefore, the same components can be used to constitute the left upper road straightening piece 230 and the right upper road straightening piece 240.

[0117] Similarly, the first lower end opening 310 and the second lower end opening 320, which are the lower end 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. Therefore, the left lower path straightening piece 330 and the right lower path straightening piece 340, which are respectively located in the left lower section guide part 301 and the right lower section guide part 302, have approximately the same structure of their accommodation spaces and are arranged in a rotationally symmetrical manner. Therefore, the same components can be used to constitute the left lower path straightening piece 330 and the right lower path straightening piece 340.

[0118] Furthermore, in this embodiment, by making the upper guide portion 200 and the lower guide portion 300 substantially the same height, the structures of the receiving spaces of the respective flow straightening pieces 230, 240, 330, and 340 are substantially the same, thereby enabling the use of the same components to construct the upper left flow straightening piece 230, the upper right flow straightening piece 240, the lower left flow straightening piece 330, and the lower right flow straightening piece 340. Thus, when manufacturing the packing module 1, only the packing piece A, the packing piece B, and the shared flow straightening piece are required, significantly reducing the production cost of the packing module 1 and significantly improving assembly efficiency.

[0119] In this embodiment, the same filler sheets A and B as those in the first embodiment can be used. In the first embodiment, the left upper guide section 201, the right upper guide section 202, the left lower guide section 301, and the right lower guide section 302 are provided with a left upper straightening sheet 230, a right upper straightening sheet 240, a left lower straightening sheet 330, and a right lower straightening sheet 340, respectively. The upper left guide portion 201 and the lower left guide portion 301 are both located on the same side of the packing module 1 (the left side of the first embodiment), and the upper right guide portion 202 and the lower right guide portion 302 are both located on the other same side of the packing module 1 (the right side of the first embodiment), that is, a fluid flows into / is introduced into the packing module 1 from one side (the left side) in the width direction of the packing module 1, and a flow path R1 of approximately the full width of the packing module 1 is formed in the heat exchange portion 400; and the fluid flows into / is introduced into the packing module 1 from the other side (the right side) in the width direction of the packing module 1, and a flow path R2 of approximately the full width of the packing module 1 is formed in the heat exchange portion 400. The thickness of R1 and R2 in the stacking direction is half of the thickness of each opening in the stacking direction, and the sum of the thicknesses of R1 and R2 is equivalent to half of the thickness of the packing module 1 in the stacking direction. This creates a same-side inflow and outflow situation. That is, if hot water flows in through the first upper opening 210 on the left upper end, it flows out of the packing module 1 through the first lower opening 310 on the left lower end. If cold air is introduced through the first lower opening 310 on the left lower end, it flows out of the packing module 1 through the first upper opening 210 on the left upper end, forming the first flow path R1. The same applies to the second upper opening 220 and the second lower opening 320 on the right upper end, except that the fluid flowing through them is different from that on the left, forming the second flow path R2. Of course, the packing module 1 can also be made similar to conventional packing modules, with hot water simultaneously flowing into each of the first and second upper openings 210 and 220, while cold air is simultaneously drawn in through the first and second lower openings 310 and 320, creating countercurrent direct contact and heat exchange between the hot water and cold air within the flow paths. However, it is not possible to have different fluids flow into the first and second flow paths R1 and R2 as described above. The hot air discharged after heat exchange has a low saturation humidity, thus preventing fogging.

[0120] Of course, the first upper opening 210 and the first lower opening 310, which serve as the upper and lower openings of the first flow path R1, can also be located on different left and right sides of the packing module. Similarly, the second upper opening 220 and the second lower opening 320, which serve as the upper and lower openings of the second flow path R2, can also be located on different left and right sides of the packing module. This has no substantial impact on the packing module 1's functionality of having two flow paths R1 and R2 separated by packing sheets A and B, as well as upper and lower openings, and is equivalent to the first embodiment described above.

[0121] [Second embodiment]

[0122] The packing module 1' of the second preferred embodiment of the present invention differs from the packing module 1 of the first embodiment in that fins are provided only in the first flow path R1, namely, an upper left fin 230 provided within the upper left guide portion 201 of the first flow path R1 and a lower left fin 330 provided within the lower left guide portion 301 of the first flow path R1. No fins are provided in the second flow path R2. Thus, in this embodiment, the first flow path R1 serves as a water spray channel, while the second flow path R2 serves as an air bleed channel.

[0123] As shown in Figures 10 to 12, by providing the flow straighteners 230 and 330 only in the first flow path R1, the spray water flowing into the packing module 1' in the first flow path R1 from the first upper opening 210, i.e., a portion of the width of the upper opening, arranged in the stacking direction and to the left of the arrow in the figure, is guided by the flow straighteners 230 in the upper left guide section 201 to substantially the entire width of the first heat exchange section 401, effectively forming a water film on the wall surfaces of the packing sheets A and B on both sides of the first flow path R1. The spray water is then guided by the flow straighteners 330 in the lower left guide section 301 to the first lower opening 310, arranged in the stacking direction and to the left of the arrow in the figure, of the packing module 1', and then flows out from a portion of the width of the lower opening of the packing module 1'.

[0124] On the other hand, the cold air introduced into the packing module 1' via the second flow path R2 from the second lower opening 320, arranged along the stacking direction to the right of the arrow in the figure, i.e., a portion of the width of the lower opening, enters the lower right guide section 302. Due to the flow properties of the gas fluid itself, the thickness of the flow path is gradually restricted by the lower guide section 302 in the stacking direction, and the width of the flow path is gradually expanded to approximately the 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 the second upper opening 220, arranged along the stacking direction, i.e., a portion of the width of the upper opening, and the thickness of the flow path in the stacking direction is gradually expanded to 2d, and then the cold air is drawn out from the second upper opening of the packing module 1'.

[0125] As can be seen, compared to the packing module 1 of the first embodiment of the present invention, in this embodiment, by removing the fins located in the upper right guide section 202 and the lower right guide section 302 of the second flow path R2 and using the second flow path R2 solely as a cold air flow path, the cold air drawn into the second flow path R2 can be made to have as little wind resistance as possible. Furthermore, because the air flow is not affected by gravity as when water flows, even without fins, while ensuring the same air flow through the second flow path R2 as in the first embodiment, the same cooling efficiency as the packing module 1 of the first embodiment can be achieved. However, since the second flow path R2 does not have fins, 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, which can effectively save electricity. Furthermore, since the packing module 1' in this embodiment can achieve lower wind resistance, it is more suitable for cooling towers that do not have fans and use a passive air suction method, such as hyperbolic cooling towers.

[0126] In this embodiment, the upper and lower openings of the first flow path R1 and the second flow path R2 are preferably located on the same side of the packing module in the width direction. This arrangement of the packing sheets A and B forms a good water-blocking structure, preventing water in the first flow path R1, where the upper left flow straightening sheet 230 and the lower left flow straightening sheet 330 are installed, from intruding through the gaps into the air flow path of the second flow path R2. This will be described in detail below.

[0127] Furthermore, in this embodiment, as shown in FIG11 , the upper end portion of the filler sheet A of the filler module 1 'is on the left side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the side of the first upper end opening 210, and the base position O of the heat exchange portion 400 of the filler sheet A is formed. A The rear half of the first upper opening 210 is formed by the filler sheet A and is offset to the rear side by a distance d / 2. Furthermore, a portion is formed on the left edge of the filler sheet A, which is offset to the front side 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 portion 400 of the filler sheet A. A The left edge portion 215A is formed by being offset forward by a distance d / 2. The left edge portion 215A extends linearly in the vertical direction.

[0128] Furthermore, at the upper end portion of the filler sheet A, on the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the side of the second upper end opening 220, the front half of the second upper end opening 210 of the second flow path R2 on the rear side formed by the filler sheet A is offset to the front side by a distance d / 2.

[0129] Furthermore, the upper end portion of the filler sheet B adjacent to the front side of the filler sheet A in the stacking direction is on the left side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the side of the first upper end opening 210, from the base position O of the heat exchange portion 400 of the filler sheet B. B The front half of the first upper opening 210 is formed by the packing piece B. The left edge of the packing piece B is formed with a distance d from the front half of the first upper opening 210 to the rear, that is, from the base position O of the heat exchange portion 400 of the packing piece B. B The left edge portion 215B is formed by being offset to the rear side by a distance of d / 2. The left edge portion 215B extends linearly in the vertical direction.

[0130] Furthermore, at the upper end portion of the filler sheet B, on the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the side of the second upper end opening 220, the rear half of the second upper end opening 210 of the second flow path R2 on the front side formed by the filler sheet B is offset to the rear side by a distance d / 2.

[0131] Thus, when filler sheet A and filler sheet B adjacent to its front side are in contact with each other for assembly, when the upper end edges of the left side portions of filler sheet A and filler sheet B, the rear half of the first upper end opening 210 of filler sheet A and the front half of the first upper end opening 210 of the front adjacent filler sheet B form a complete first upper end opening 210, and on the left side of the first upper end opening 210, the left sealing edge 215A of filler sheet A and the left sealing edge 215B of filler sheet B are brought close to each other from top to bottom.

[0132] Thus, the first flow path R1 formed by packing sheet A and its adjacent packing sheet B in front of it has an inlet with a thickness of 2d, namely, a first upper end opening 210. Its left seal 215 is formed by a left seal portion 215A and a left seal portion 215B that are offset and close together. This left seal 215 easily forms a sealed structure during joint sealing. When this first flow path R1 is used as a hot water shower, since hot water enters through the first upper end opening 210, which is arranged in a front-to-back arrangement on the left side of the packing module 1', it is unlikely to leak out of the left seal 215 when it is directed into the heat exchange unit 400.

[0133] On the other hand, after the hot water is introduced into the heat exchange unit 400 through the first upper opening 210, the water flows under its own gravity along the rear wall of the front and rear packing sheets B and the front wall of the packing sheet A within the heat exchange unit 400, and will not easily intrude into the right side seal of the packing module 1'. Therefore, the sealing requirements for the right side seal are significantly reduced.

[0134] Specifically, in this embodiment, if the lower guide section 300 is rotated 180° about a horizontal axis perpendicular to the stacking direction, its structure becomes identical to that of the upper guide section 200. Similar to the upper guide section 200, the lower guide section 300 has an offset arrangement of the lower edges of the packing sheet A and its adjacent front packing sheet B. This creates a continuous left edge seal 215A, 215B along the left edges of the packing sheets A and B, extending from top to bottom and including the left edge of the heat exchange section 400. This effectively prevents water from seeping through the left edge seal 215, particularly between the upper and lower guide sections 200 and 300.

[0135] Furthermore, in this embodiment, while any joining method can be used for the edge seal 215 formed by the left edge seals 215A and 215B, pressure welding is preferably used for the edge seal 210 from the perspective of assembly convenience. This is because, when using equipment to assemble the filler sheets A and B and the rectifier sheets 230 and 330, simply by aligning the filler sheets B adjacent to each other in the front-to-back direction, since the filler sheets A and B are offset and close to each other at the right portions of their upper and lower edges, the pressure welding equipment can be operated in this state to weld the edge seal 215 and the right portions of the upper and lower edges of the filler sheet BA to complete the welding operation of the filler sheet BA.

[0136] By inserting the rectifier sheets 230 and 330 between the packing sheets BA and welding the edge seal 215 to the right portions of the upper and lower edges of the packing sheets BA, the packing sheets BA in the stacking direction can be combined to form a module with a very high structural stability. The modules formed by multiple packing sheets BA can then be combined and bonded in the stacking direction. The high strength and stability of a single module greatly reduces the difficulty of module assembly and improves the efficiency of assembling the packing sheet BA modules into the packing module 1'.

[0137] In the drawings of this embodiment, for ease of assembly and processing, the right side seal is not structured identically to the left side seal 215. However, this does not limit the structure of the right side seal; the same structure as the left side seal 215 can also be employed.

[0138] [Third embodiment]

[0139] A third embodiment of a packing module 1 ″, as a preferred embodiment of the present invention, as shown in Figures 13 and 14 , differs from the packing module 1 of the first embodiment described above in the configuration and assembly of the upper left flow straightening piece 230 , the upper right flow straightening piece 240 , the lower left flow straightening piece 330 , and the lower right flow straightening piece 340 and their corresponding first upper end opening 210 , second upper end opening 220 , first lower end opening 310 , and second lower end opening 320 .

[0140] In this embodiment, the upper edges of the left upper road straightening piece 230 and the right upper road straightening piece 240 are respectively lower than the first upper end opening 210 and the second upper end opening 220, that is, the upper edges of the left upper road straightening piece 230 and the right upper road straightening piece 240 are respectively located on the inner sides of the first upper end opening 210 and the second upper end opening 220.

[0141] Similarly, the upper edges of the left lower road straightening piece 330 and the right lower road straightening piece 340 are respectively higher than the first lower end opening 310 and the second lower end opening 320, that is, the lower edges of the left lower road straightening piece 330 and the right lower road straightening piece 340 are respectively located on the inner side of the first lower end opening 310 and the second lower end opening 320.

[0142] That is, in this embodiment, the opening-side ends of the flow straighteners 230, 240, 330, and 340 are positioned a predetermined distance h inward of the corresponding upper and lower openings 210, 220, 310, and 320, respectively. Figures 13 and 14 illustrate only the upper left flow straightener 230 as an example, but the other flow straighteners 240, 330, and 340 can be similarly configured.

[0143] When stacking filler sheets A and B, at the upper left guide portion 201 , filler sheet A is biased toward the rear side in the stacking direction, while filler sheet B is biased toward the front side in the stacking direction, so their upper left edges are close to the edge of the first upper end opening 210 .

[0144] Because the rectifier sheet 230 embedded in the left upper guide portion 201 is located inside the first upper opening 210, it avoids the upper edge of the filler sheet AB at the first upper opening 210 in the stacking direction, maintaining a distance h. This allows welding to be performed with a heated fixture in this avoided area, forming a weld track L.

[0145] In the first and second embodiments, the rectifier blades 230 are not retracted into the first upper opening 210. During welding, interference from the flexed rectifier blades arranged at the end surface of the first upper opening 210 results in only intermittent welds that can accommodate the flexure of the rectifier blades 230. Furthermore, the left upper edge of the filler sheet AB can only be sealed by applying glue after the filler sheet AB is brought together.

[0146] In contrast, in this embodiment, by retracting the rectifying piece into the first upper end opening 210, the left upper end edge of the filler piece AB can be continuously pressure-welded using the escape area.

[0147] In this way, on the one hand, the connection strength of the left upper end edge of the packing sheet AB is improved, so that after the packing sheets A and B are stacked in multiple layers, the overall strength of the packing module 1" can be significantly improved.

[0148] More importantly, when the left first flow path R1 is used as a hot water spray path and the right second flow path R2 is used as an air flow path, the inner side of the left upper end seam of the packing sheet AB, which forms the first upper end opening 210, is connected to the second flow path R2. By welding this seam, the watertightness is effectively improved, preventing water leakage caused by debonding over time.

[0149] Furthermore, in this embodiment, by positioning the first lower end opening 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 sheets A and B, respectively, the probability of leakage from the upper end of the first flow path R1 into the second flow path when the first flow path R1 is used as a hot water spray flow path can be minimized; the left side can also be sealed by welding to prevent leakage.

[0150] As for the right side, since the first flow path R1 guides the hot water from a part of the width on the left side to the approximately full width of the heat exchange part, and then returns to a part of the width on the left side and flows out from the first lower end opening 310, it is difficult for the hot water to overflow from the right edge under the action of gravity. Therefore, the right side edge sealing can be achieved by a simple convex-concave joint method for interlocking connection, bonding, spot welding, etc.

[0151] Of course, if a slight increase in cost is not a concern, the right side sealing method can also be used in the same manner as the left side sealing method. Of course, the right side sealing method can also be formed by offsetting the right edge of the heat exchange portion 400 of the packing sheets A and B in the same direction as the left edge. This can completely seal the first flow path.

[0152] In this embodiment, only the configuration of the upper left slat 230 and the first upper opening 210 in the upper left guide section 201 is described as an example. The same configuration can also be used for the second upper opening 220, the first lower opening 310, the second lower opening 320, and the corresponding slats 240, 330, and 340. This improves the overall strength of the packing module 1″, particularly the upper and lower end surfaces of the packing module 1″ having the upper and lower openings 210, 220, 310, and 320 arranged in parallel. This significantly enhances the robustness, reliability, and durability of the packing module 1″ during transportation, handling, installation, and daily operation.

[0153] [Fourth embodiment]

[0154] In the first embodiment, the first upper opening 210 and the first lower opening 310 can be located on the left side of the packing module and have the same width, while the second upper opening 220 and the second lower opening 320 can be located on the right side of the packing module and have the same width, i.e., they are on the same side and have the same width. This allows packing sheet A and packing sheet B to be composed of the same components, reducing the manufacturing cost of the packing module. In other words, packing sheet B (i.e., the flipped packing sheet A) can be flipped 180° relative to the horizontal axis relative to packing sheet A. Therefore, the description of packing sheet B in this embodiment is based on the position of packing sheet A before flipping.

[0155] The filler sheet A is constructed such that an upper left biased portion biased toward the rear side is provided on the left side of the upper end portion; an upper right biased portion biased toward the front side is provided on the right side of the upper end portion; a lower left biased portion biased toward the rear side is provided on the left side of the lower end portion; and a lower right biased portion biased toward the front side is provided on the right side of the lower end portion, and the adjacent filler sheets B are arranged in a manner of being flipped 180° around the horizontal axis of the main body of the filler sheet A.

[0156] As a result, the upper right offset portion of filler sheet A is brought together with the lower right offset portion of filler sheet B located at the front side in the stacking direction; the lower right offset portion of filler sheet A is brought together with the upper right offset portion of filler sheet B, thereby forming a first upper end opening 210 between the upper left offset portion of filler sheet A and the lower left offset portion of filler sheet B, and forming a first lower end opening 310 between the lower left offset portion of filler sheet A and the upper left offset portion of filler sheet B. The first upper end opening 210 and the first lower end opening 310 are respectively connected to the first heat exchange portion 401 formed between the main body of filler sheet A and the main body of filler sheet B in the upper and lower directions, thereby forming a first flow path R1.

[0157] The upper left offset portion of filler sheet A is placed together with the lower left offset portion of filler sheet B located at the rear side in the stacking direction; the lower left offset portion of filler sheet A is placed together with the upper left offset portion of filler sheet B, thereby forming a second upper end opening 220 between the upper right offset portion of filler sheet A and the lower right offset portion of filler sheet B, and forming a second lower end opening 320 between the lower right offset portion of filler sheet A and the upper right offset portion of filler sheet B. The second upper end opening 220 and the second lower end opening 320 are respectively connected to the second heat exchange portion 402 formed between the main body of filler sheet A and the main body of filler sheet B in the upper and lower directions, thereby forming a second flow path R2.

[0158] Furthermore, a left upper path straightening piece 230 is provided between the left upper offset portion of the packing piece A and the left lower offset portion of the packing piece B, the width of which gradually increases and the thickness of which gradually decreases from the first upper end opening 310 to the first heat exchange portion 401 .

[0159] A left lower path straightening piece 330 is provided between the left lower offset portion of the packing piece A and the left upper offset portion of the packing piece B. The left lower path straightening piece 330 gradually increases in width and decreases in thickness from the first lower end opening 310 to the first heat exchange portion 401 .

[0160] Similarly, a right upper path straightening piece 240 is provided between the right upper offset portion of the packing piece A and the right lower offset portion of the packing piece B, with the width gradually increasing and the thickness gradually decreasing from the second upper end opening 220 to the second heat exchange portion 402 .

[0161] Between the lower right offset portion of the packing piece A and the upper right offset portion of the packing piece B, a lower right flow straightening piece 340 is provided, which gradually increases in width and decreases in thickness from the second lower end opening 320 to the second heat exchange portion 402 .

[0162] On this basis, if the left edge of each filler sheet A is offset forward as in the second embodiment, a linear edge portion 215A is formed, and the edge portion of the filler sheet A and the edge portion 215B of the filler sheet B located at the front side in the stacking direction are close to each other.

[0163] The edge sealing portion 215A of the packing sheet A and the edge sealing portion 215B of the packing sheet B located at the front side in the stacking direction are brought together and welded together to form the left edge sealing portion 215 .

[0164] Therefore, according to this embodiment, the number of components can be further reduced. When assembling the packing module using the packing sheets, it is only necessary to sequentially stack the uninverted packing sheet A and the packing sheet B inverted 180 degrees.

[0165]

Cooling Tower 1

[0166] FIG10 is a schematic diagram of a cooling tower manufactured based on the filler module 1 of this embodiment.

[0167] The bottom layer of the cooling tower 10 is an air intake layer 101, and a plurality of dampers 102 are provided around the air intake layer 101. A packing layer 103 is provided above the air intake layer 101. The packing layer 103 is arranged in a matrix shape on a horizontal plane by a plurality of packing modules 1. A spraying section 104 is provided above the packing layer 103, and the spraying section 104 sprays the hot water to be treated onto each packing module 1 of the packing layer 103. A partition 105 extending in the stacking direction of the packing modules 1 is generally vertically provided in the area between the spraying section 104 and the packing layer 103, and a plurality of partition spaces 105a and 105b are enclosed by the partition 105 and the top surface of the packing module 1, wherein the partition space 105a serves as a spray space for spraying hot water, and the partition space 105b serves as an air induction space for sucking gas from bottom to top. The spray space 105a and the air entrainment space 105b are alternately arranged in a direction perpendicular to the stacking direction of the matrix composed of the packing modules 1, and each partition 105 is arranged at the intersection of the first upper end opening 210 and the second upper end opening 220 of the packing module 1, thereby separating the first flow path R1 and the second flow path R2 connected to the first upper end opening 210 and the second upper end opening 220.

[0168] Above the spray section 104 is the exhaust layer 106, and above the exhaust layer 106 is an exhaust port 108 provided with a fan 107. The fan 107 draws air upward, so that cold air enters the air intake layer 101 from the damper 102 in the lower layer of the cooling tower 10, passes upward through the packing modules 1 of the packing layer 103, passes through the spray space 105a and the air intake space 105b respectively, is further mixed in the exhaust layer 106, and is discharged upward through the exhaust port 108.

[0169] On the other hand, the hot water to be treated sprayed from the spraying part 104 to each packing module 1 of the packing layer 103 is cooled by each packing module 1 and falls to the bottom surface of the air inlet layer 101. The cooled water is recovered through the collection equipment for recycling in the factory.

[0170] Working status 1:

[0171] As described above, the cooling tower 10 is set to winter operation. At this time, the hot water 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, because the partition 105 is positioned at the intersection of the first upper end opening 210 and the second upper end opening 220 relative to the packing module 1, 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, adjacent to the second and first flow paths on either side, respectively, form air flow paths.

[0172] In the water flow path, spray water flows into packing module 1, passes through upper guide 200, and forms a water film in the heat exchange section 400, distributed within a flat space that spans approximately the entire width of packing module 1. The water film adheres to the walls of the flat space on both sides in the stacking direction. The adjacent flow paths on both sides in the stacking direction serve as air flow paths, exchanging heat with the hot water in the water flow path through the walls of packing sheets A and B.

[0173] During winter operation, cooling tower 10 draws air from below packing module 1 into the air flow path as dry, cold air with a low temperature and low moisture content. As the air passes through packing module 1 and exchanges heat with hot water, the heat exchange occurs in independent flow paths separated by packing sheets A and B. Therefore, when the air is discharged from the top of packing module 1, its temperature rises, but its moisture content remains unchanged, resulting in dry, hot air.

[0174] On the other hand, because hot water is sprayed from the shower head 104 above the water flow path, the air drawn in by the fan 107 in the water flow path encounters significant resistance. Therefore, the air flow rate is very small compared to the air flow through the air flow path, typically only a fraction of the total. The air that does flow through the air flow path becomes hot, saturated air, i.e., hot and humid air.

[0175] The dry hot air flowing through the air flow path and the humid hot air flowing through the water flow path are mixed in the exhaust layer 106. Since there is less humid hot air, unsaturated hot air is formed after mixing with the dry hot air. After being discharged into the atmosphere through the fan 107 and the exhaust port 108, the unsaturated hot air is gradually cooled and less water is precipitated, which greatly reduces the amount of fog formed.

[0176] In this embodiment, by switching the spray part 104, the spray space 105a and the air entrainment space 105b can be flexibly switched, that is, stop spraying hot water on the spray space 105a, and spray hot water on the air entrainment space 105b. In this way, the functions of the spray space 105a and the air entrainment space 105b can be swapped. On the one hand, the normal operation of the cooling tower 10 can be guaranteed, and on the other hand, the flow path R1 or R2 of the packing module 1 connected to the air entrainment space 105b can be effectively cleaned and maintained, so that when the cooling tower 10 is cleaned and maintained, the normal operation of the cooling tower 10 is not affected.

[0177] Working status 2:

[0178] When working in summer, the spraying part 104 can be adjusted to spray hot water to the bleed space 105b and the spraying space 105a in the same manner, thereby ensuring that the cooling tower 10 has the heat exchange efficiency as high as possible without fogging in summer.

[0179]

Cooling Tower 20

[0180] In this embodiment, the filler module 1 is still used as the cooling tower 20 , and only the differences from the cooling tower 10 are described in detail, and the same structures are not repeated.

[0181] The cooling tower 20 of this embodiment differs from the aforementioned cooling tower 10 in that, for each spray space 105a, a cover plate 109 is further disposed approximately horizontally above the partition 105, along the stacking direction of the packing modules 1. The cover plates 109, partitions 105, and packing modules 1 define a plurality of partition spaces 205a and 205b. In this embodiment, the cover plates 109 are only disposed in the spray space 205a, where hot water is sprayed, and are not disposed in the bleed air space 205b, where exhaust is performed. Of course, cover plates 109 may also be disposed in both the spray space 105a and the bleed air space 205b. Furthermore, the cover plates 109 may be configured as a continuous plate or a combination of multiple plates. The cover plates 109 may be configured to be removable or openable by flipping or splitting along one or both sides of the partition 105, thereby enabling switching between the spray space 205a and the bleed air space 205b.

[0182] Working status 1:

[0183] This working state is particularly suitable for winter in northern my country. In this state, the working process of the cooling tower 20 is similar to that of the above-mentioned cooling tower 10, except that a cover plate 109 is provided above the spray space 205a. Therefore, the spray space 205a does not play the role of air entrainment in principle. Only hot water flows downward through the flow path R1 or R2 of the filler module corresponding to the spray space 205a. Therefore, in the exhaust layer 106 of the cooling tower 20, there is only dry hot air from the air entrainment space 205b.

[0184] Therefore, only dry hot air is drawn from the cooling tower 20 through the fan 107 and discharged from the exhaust port 108, so that the moisture in the hot air discharged from the cooling tower 20 is reduced as much as possible, thereby further improving the defogging ability of the cooling tower 20 in winter. Moreover, since the discharged air is only dry hot air, the amount of moisture discharged from the cooling tower 20 is also less, which is more conducive to water saving.

[0185] When both the spray space 205a and the bleed air space 205b are provided with openable and closable (flat opening, split opening or removable) covers 109, by opening the cover above the spray space 205a and closing the cover above the bleed air space 205b, and adjusting the spray part 104, the functions of the spray space 205a and the bleed air space 205b can be exchanged in the same way as the above-mentioned cooling tower 10, and the flow path R1 or R2 of the packing module 1 corresponding to the original bleed air space 205b can be cleaned, thereby avoiding shutdown of the cooling tower 20.

[0186] Of course, by only opening the cover plate 109, the same operating state as the above-mentioned cooling tower 10 can be achieved, and its operating efficiency and working results are also roughly the same.

[0187] Working status 2:

[0188] In the summer working state, by removing or opening the cover 109 above the spray space 205a, the spray part 104 is adjusted so that hot water is sprayed to the air intake space 205b and the spray space 205a in the same manner, so that the cooling tower 20 can achieve the same working state of improving the heat exchange efficiency in summer as the above-mentioned cooling tower 10.

[0189] In the cooling tower 20 of this embodiment, the cover plate 109 arranged above the partition spaces 205a and 205b is a flat plate, but is not limited to this. It can also be a plate extending from the partition plates 105 on both sides of the stacking direction of the filler modules 1 of the partition spaces 205a and 205b to the middle, and overlapping to close the partition spaces 205a and 205b, forming an upward or downward top angle at the overlapping point, that is, as long as the upper part of the partition spaces 205a and 205b can be closed, there is no restriction on the structure of the cover plate 109.

[0190] In the above embodiment, the flow straightening piece 230 is provided in the upper left guide portion 201 of the upper flow guide portion 200 of the first flow path R1 formed between the packing pieces BA in the stacking direction of the packing modules 1 .

[0191] Furthermore, the flow straightening piece 240 is provided in the right upper stage guide portion 202 of the upper stage flow guide portion 200 of the second flow path R2 , which is formed between the packing pieces AB in the stacking direction.

[0192] On the other hand, the flow straightening piece 330 is provided in the left lower stage guide portion 301 of the lower stage flow guide portion 300 of the first flow path R1 , which is formed between the packing pieces BA in the stacking direction.

[0193] Furthermore, the flow straightening piece 340 is provided in the right upper stage guide portion 202 of the lower stage flow guide portion 300 of the second flow path R2 , which is formed between the packing pieces AB in the stacking direction.

[0194] Since the first upper opening 210 and the second upper opening 220 each occupy approximately half the width of the packing module 1, the flow straightening sheet 230 is actually embedded in a roughly rectangular trapezoidal area extending from the approximately middle of the upper edge of the packing sheet BA, downward through the left edge of the upper guide portion 200, along the lower end line of the upper guide portion 200 to the right to the right edge of the upper guide portion 200, and then diagonally upward to the approximately middle of the upper edge of the packing sheet A (B). The packing sheet A is offset toward the rear in this rectangular trapezoidal area, while the packing sheet B is offset toward the front. Therefore, in the stacking direction, the front packing sheet A and the rear packing sheet B, i.e., the packing sheet AB, form a close bond around the periphery of the first upper opening 210. Therefore, the width of the opening between the front packing sheet B and the rear packing sheet A and packing sheet BA at the first upper opening 210 in the stacking direction is 2d. That is to say, within the area of ​​the right-angled trapezoid, the distance in the stacking direction at the first upper end opening 210 at the upper end is approximately 2d, and the distance in the stacking direction at the part where the lower end is connected to the heat exchange part 400 is the interval d between the filler sheets A and B, thereby forming a space for the upper left section guide part 201.

[0195] The horizontal cross-section of the flow straightener 230 is a zigzag shape extending perpendicular to the stacking direction. The upper portion, located near the first upper opening 210, has a large zigzag amplitude and a small zigzag span. As it extends downward toward the heat exchange section 400, the zigzag amplitude gradually decreases and the zigzag span gradually increases, filling the space in the upper left guide section 201. By zigzagging the flow straightener 230 horizontally, 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 hot water flowing in from the first upper opening 210, which spans approximately half the width of the packing module 1, to the heat exchange section 400, which spans approximately the full width of the packing module 1. Furthermore, the cross-sectional area of ​​each guide flow path, whether individual or as a whole, varies minimally from top to bottom to reduce fluid resistance. Good passing efficiency can be achieved for hot water sprayed from above and air sucked from bottom to top.

[0196] The flow straightening piece 240 located in the space of the upper right guide portion 202 has the same structure, except that the position of the flow straightening piece 240 is rotationally symmetrical with respect to the horizontal direction.

[0197] Similar to the upper left guide section 201 and upper right guide section 202 of the upper guide section 200, the flow straighteners 330 and 340 are respectively disposed within the lower left guide section 301, formed by offsetting the inverted right-angled trapezoidal region of the packing sheet BA in the lower guide section 300 outward in the stacking direction, and the lower right guide section 302, formed by offsetting the inverted right-angled trapezoidal region of the packing sheet AB in the lower guide section 300 outward in the stacking direction. The flow straighteners 330 and 340 form multiple flow paths in the lower left guide section 301 and lower right guide section 302, respectively, each having a thinner thickness in the stacking direction and a wider width in the horizontal direction at the upper end, and a thicker and narrower width at the lower end. This guides water from the heat exchange section 400, which spans approximately the full width of the first and second flow paths R1 and R2 of the packing module 1, to the first and second lower end openings 310 and 320, which span approximately half the width.

[0198] That is, for the rectifier plates 330 and 340, they are inverted, with a large flexure amplitude and a small flexure span at the first and second lower end openings 310 and 320. In the process of extending from bottom to top toward the heat exchange portion 400, the flexure amplitude gradually decreases and the flexure span gradually increases.

[0199] The flow straightening piece 330 located in the space of the left lower stage guide portion 301 and the flow straightening piece 340 located in the space of the right lower stage guide portion 302 are similarly rotationally symmetric in the horizontal direction.

[0200] Therefore, when the first and second upper openings 210, 220 and the first and second lower openings 310, 320 are approximately half the width of the filling module 1, if the vertical lengths of the upper and lower section guides 200, 300 are the same, the left upper section guide 201, the right upper section guide 202, the left lower section guide 301, and the right lower section guide 302 can form a rotationally symmetrical structure, so that the straightening pieces 230, 240, 330, 340 can be made into the same components, so that the filling module 1 only needs three components during production, namely, the filling piece A, the filling piece B and the universal straightening piece. This not only significantly reduces the mold cost and the component production cost for producing the filling module 1, but also does not need to consider the model differences of each straightening piece when assembling the filling piece A, the filling piece B and the straightening piece, making assembly convenient, thereby greatly reducing the overall production cost of the filling module 1.

[0201] According to the above preferred embodiment, by offsetting and fitting the filler sheet A and the filler sheet B in the upper guide portion and the lower guide portion respectively, the first upper end opening, the second upper end opening, the first lower end opening and the second lower end opening are respectively stacked in the stacking direction. Without considering the thickness of the filler sheets A and B, the total size of the openings in the stacking direction is roughly consistent with the stacking thickness of the filler module in the stacking direction.

[0202] [Fifth embodiment]

[0203] Similar to the aforementioned embodiments, packing module 1000 of this embodiment also employs a configuration comprising a plurality of alternately stacked packing sheets. A first flow path and a second flow path are formed between the plurality of packing sheets 1000A and 1000B, respectively. Specifically, as shown in FIG17 , in the stacking direction of the packing module, from front to back, a first flow path 1000G is formed between packing sheets 1000A and 1000B, while a second flow path 1000W is formed between packing sheets 1000B and 1000A.

[0204] The difference from the above-mentioned embodiments lies in the location of the upper openings of the first flow channel 1000G and the second flow channel 1000W. In this embodiment, the upper opening G of the first flow channel 1000G, serving as the first upper opening, is located in the middle of the upper left-right direction of the packing module 1000. The upper opening W of the second flow channel 1000W, serving 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. In other words, in this embodiment, the second flow channel 1000W has two upper openings W, which are arranged to sandwich the upper opening G of the first flow channel 1000G.

[0205] In this embodiment, the upper end opening G of the first flow path 1000G is connected to the first heat exchange part 401 of the first flow path 1000G through the upper guide part of the first flow path 1000G, and the upper end opening G located in the middle part in the width direction of the upper end of the filling module 1000 is guided to the first heat exchange part 401 occupying approximately the entire width of the filling module 1000.

[0206] The two upper end openings W1 and W2 of the second flow path 1000W are connected to the second heat exchange part 402 of the second flow path 1000W through the upper guide part of the second flow path 1000W, and the upper end openings W1 and W2 on both sides of the upper end opening G of the first flow path 1000G in the upper width direction of the filling module 1000 are guided to the second heat exchange part 402 which occupies approximately the entire width of the filling module 1000.

[0207] Specifically, in the front-to-back direction of the illustrated stacked packing sheets, a first flow path 1000G is formed between packing sheet 1000B and packing sheet A, and a second flow path 1000W is formed between packing sheet 1000A and packing sheet 1000B. Between the heat exchange section 401 of first flow path 1000G and the heat exchange section 402 of second flow path 1000W, the distance between packing sheet 1000A and packing sheet 1000B is substantially uniform. That is, packing sheet 1000A and packing sheet 1000B are arranged substantially parallel to each other in portions of first heat exchange section 401 and second heat exchange section 402.

[0208] Furthermore, for the packing sheets A and B, the upper guide portion 200 of the first and second flow paths 1000G and 1000W is provided on the heat exchange portion 400 including the stacked first and second heat exchange portions 401 and 402 .

[0209] In this embodiment, the filler sheets 1000B and 1000A are offset in opposite directions from the upper end opening G toward the first heat exchange section 401 in the upper guide section 200, thereby forming first offset portions 1100B and 1100A. This increases the distance between them, thereby forming the first upper end opening 1100 of the first upper guide section 200G. Furthermore, the formation of the first offset portions 1100A and 1100B in the upper guide section 200 of the filler sheets 1000A and 1000B causes the filler sheets 1000A and 1000B to be brought closer together in that portion.

[0210] On the other hand, filler sheets 1000A and 1000B are offset in opposite directions from upper openings W1 and W2 on both sides of upper opening G toward the second heat exchange section 402 in the upper guide section 200, thereby forming second offset portions 1200A and 1200B and increasing the distance between them, thereby forming a second upper opening 1200 of the second upper guide section 200W. Furthermore, the formation of second offset portions 1200B and 1200A in the upper guide section 200 of filler sheets 1000B and 1000A causes filler sheets 1000B and 1000A to be brought close together in that portion.

[0211] In this embodiment, by forming offset portions in the upper sections of the packing sheets 1000A and 1000B as described above, a first upper opening 1100 and a second upper opening 1200 are formed in 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 and second upper openings 1100 and 1200. Consequently, in the first flow path 1000G, the first upper opening G, which occupies a portion of the width of the middle portion of the packing module 1000, communicates with the first heat exchange section 401, which occupies substantially the entire width of the packing module 1000. Furthermore, in the second flow path 1000W, the second upper openings W1 and W2, which extend along the width of the packing module 1000, communicate with the second heat exchange section 402, which occupies substantially the entire width of the packing module 1000. As can be seen from this, in one unit of the second flow path 1000W formed by the filler sheets 1000A- 1000B, the second upper end openings W1 and W2 of the second flow path 1000W communicate with the common second heat exchange portion 402 .

[0212] Furthermore, the thickness of the first and second upper openings G, W1 and W2 in the stacking direction of the filler module 1000 is greater than the distance between the corresponding filler sheets 1000A and 1000B in the stacking direction at the heat exchange unit 400 .

[0213] In the present embodiment, in order to make the fluid in the first flow path 1000G and the second flow path 1000W uniform, straightening fins are further provided in the first and second upper guide portions 200G and 200W, respectively.

[0214] The first straightening plate 1300G in the first flow path 1000G is disposed within the first upper guide portion 200G, extending from the first upper end opening G to the first heat exchange portion 401. The first upper guide portion 200G serves to connect the first upper end opening G to the substantially full width of the first heat exchange portion 401. Therefore, the first straightening plate 1300G disposed within the first upper guide portion 200G is formed in a substantially isosceles trapezoidal shape, having a plurality of guide grooves that gradually increase in width from top to bottom.

[0215] Furthermore, the second flow straightener 1300W, which serves as the second flow path 1000W, is disposed within the second upper guide portion 200W, extending from the second upper end openings W1 and W2 to the second heat exchange portion 402. The second upper guide portion 200W serves to connect the second upper end openings W1 and W2 to the substantially full width of the second heat exchange portion 402. Therefore, the second flow straightener 1300W disposed within the second upper guide portion 200W is formed into two roughly right-angled trapezoidal shapes, having a plurality of guide grooves that gradually increase in width from top to bottom.

[0216] In this embodiment, as described above, because the front projection of the filler sheets 1000A and 1000B is roughly rectangular, the first upper end opening 1100 of the first upper guide portion 200G formed by the first offset portions 1100B and 1100A is formed into a roughly inverted triangle. Furthermore, the second upper end opening 1200 of the second upper guide portion 200W formed by the second offset portions 1200A and 1200B is formed into a roughly inverted right triangle located at the left and right corners of the upper ends of the filler sheets 1000A and 1000B. In this case, the first upper end opening G and the second upper end openings W1 and W2 are located at the upper edge of the filler module 1000.

[0217] Thus, inverted, roughly triangular, and inverted, roughly right-angled, longitudinal rectifying sections are also formed in the first rectifying piece 1300G and the second rectifying piece 1300W at locations corresponding to the first and second upper openings 1100, 1200 of the first and second upper inlet sections 200G, 200W. These longitudinal rectifying sections serve to pre-separate the first and second upper guide sections 200G, 200W of the first and second flow paths 1000G, 1000W, ensuring a roughly uniform flow rate within each guide groove in the oblique rectifying section below them.

[0218] Furthermore, in this embodiment, in addition to forming the first and second upper end openings 1100 and 1200 by providing offset portions in the first and second upper guide portions 200G and 200W, and providing first and second flow straightening segments 1300G and 1300W, the first and second lower end guide portions 400G and 400W can be formed by providing similar offset portions and providing third and fourth flow straightening segments 1300G' and 1300W', thereby forming the same first and second lower end openings.

[0219] When constructing a cooling tower based on the filler module of this embodiment, a plurality of filler modules can be arranged in parallel in a substantially horizontal direction.

[0220] (Use Example 1)

[0221] In this embodiment, since the first upper end opening G of the first flow path 1000G is located in the middle of the width direction of the filling module 1000, and the second upper end opening W of the second flow path 1000W is located on both sides of the width direction of the filling module 1000, when the filling modules 1000 are arranged in parallel, as shown in Figure 27, a schematic diagram of the use example 1 of the filling module 1000 of this embodiment is shown.

[0222] Unlike the first to fourth embodiments, in this usage example, the lower end of the partition 2005 (i.e., the first partition) arranged above the filling module 1000 for separating the air flow path and the spray water flow path, and the sealing part between the filling module 1000 are both located on the inner side of the width direction of the filling module, and there will be no situation where the lower end of the partition 105 is located at the intersection of the filling modules as mentioned above.

[0223] Specifically, the partition plate 2005 extends along the stacking direction, and the lower end of the partition plate 2005 corresponds to the connection between the first upper end opening G and the second upper end opening W in the width direction of the filling module 1000 .

[0224] In this way, the sealing between the filling module 1000 and the partition 2005 is easier, and the spray flow path and the air flow path are separated as thoroughly as possible, so that the absolute humidity of the cold air flowing in from the bottom of the filling module 1000 remains unchanged after passing through the filling module 1000, exchanging heat with the hot water in the adjacent flow path, and being discharged to the top of the filling module 1000.

[0225] However, the heat-exchanged air discharged above the filler module 1000 exchanges heat with the hot water in the adjacent flow path and becomes dry hot air. While maintaining the absolute humidity, the air temperature increases and the relative humidity decreases significantly.

[0226] In this use case, a partition 2005' (i.e., a second partition) is also provided below the filling module 1000. Specifically, the partition 2005' extends along the stacking direction, and the lower end of the partition 2005' corresponds to the connection between the first lower end opening and the second lower end opening in the width direction of the filling module 1000. Therefore, in the cooling tower 2000, the sprayed hot water after passing through the filling module 1000 supplies as little moisture as possible to the cold air sucked in below the filling module 1000. In the filling module 1000, the cold air is isolated from the hot water in the adjacent flow path, and moisture is not supplied to the air flow path. Furthermore, when the sucked cold air is discharged above the filling module 1000, the separation by the partition 2005 further avoids the acquisition of moisture from the spraying portion.

[0227] Therefore, in this use case, by isolating the air flow path and the spray water as much as possible within cooling tower 2000, moisture supplied to the intake air can be minimized. Furthermore, in the spray water flow path, a closed valve plate 2009 is provided above the nozzle, minimizing the mixing of hot vapor from the spray water into the exhaust air. Furthermore, the hot vapor is also separated from the intake cold air below filler module 1000 by partition plate 2005'. Thus, the spray water forms a closed flow path, minimizing moisture supply to both the intake and exhaust air of cooling tower 2000. Consequently, even in winter in northern my country, mist discharged from cooling tower 2000 can be significantly reduced.

[0228] (Usage Example 2)

[0229] In addition, the valve plate 2009 can also be set to an invalid state (open or not set), becoming the state shown in Figure 28. Even so, the cold air sucked in from below the filling module 1000, after the cold air is discharged to the top of the filling module, only a small amount of water vapor above the partition 2005 is mixed with the cold air after heat exchange.

[0230] Because the temperature of the cold air after heat exchange increases while the absolute humidity remains unchanged, the saturation is low. Meanwhile, the amount of moisture from the spray flow path itself is limited. Therefore, the air after heat exchange, whose saturation has significantly decreased, can be effectively utilized to absorb the moisture released from the spray section. Cooling tower 2100 in this Use Case 2 can effectively achieve a defogging effect, even in winter, when temperatures are extremely low.

[0231] In Examples 1 and 2, first flow path 1000G is used as an air flow path, and second flow path 1000W is used as a hot water shower flow path. Therefore, the area between adjacent packing modules 1000 is limited to the hot water shower flow path. In this case, while ensuring airtightness between the lower end of partition plate 2005 and packing module 1000, first flow path 1000G, acting as the air flow path, allows the entirety of air drawn into cooling tower 2000 to flow through first flow path 1000G as much as possible.

[0232] As for the installation of the packing modules, there will inevitably be certain gaps between the parts of the packing modules, otherwise the installation of the packing modules will become a problem. According to the packing module 1000 of this embodiment, by setting the first upper end opening G in the middle of the width direction of the packing module 1000, and setting the second upper end opening W on both sides of the width direction of the packing module 1000, the adjacent upper end openings between adjacent packing modules 1000 can be the second upper end opening W, so that the second upper end opening W can be set as the inlet for hot water spraying. Thereby, the problem of air leakage in the installation gaps between the packing modules 1000 can be effectively reduced. As in the first to fourth embodiments, there will inevitably be gaps between the packing modules 100 set in the air flow path, so that a part of the air does not pass through the packing module and flows directly through the gaps between the packing modules 100, which may cause the problem of reduced heat exchange efficiency. Furthermore, if the gaps between the packing modules 100 are too large due to construction errors or mistakes, the air flow rate flowing through the gaps between the packing modules 100 will increase significantly, making it impossible 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 the heat exchange efficiency between the packing modules.

[0233] The use of the filling module 1000 of this embodiment can properly solve the above problems.

[0234] (Use Example 3)

[0235] As a third use case of the filler module 1000 of this embodiment, in addition to the advantages of the aforementioned use cases 1 and 2, it can further improve the heat exchange efficiency of the cooling tower, significantly reduce the cost of the filler module, and further enhance the convenience of installation and maintenance. Detailed description is given below.

[0236] In this use example, as shown in FIG. 29 , a cooling tower 3000 is constructed using the filler modules 1000 . Hereinafter, only the differences between the cooling tower 3000 and the aforementioned embodiment will be described.

[0237] In cooling tower 3000, unlike the aforementioned structure, a predetermined installation spacing 3999 of 300-600 mm is provided between each filler module 1000, and preferably, a sealing plate 3998 is provided on the surface of the mounting seat where the filler modules 1000 are spaced apart. If sealing plates 3998 are not provided, the support beams serving as mounting seats for the filler modules 1000 can be formed to have a flat surface corresponding to the spacing between the filler modules 1000.

[0238] At this time, contrary to the above-mentioned usage examples 1 and 2, it is preferable to use the second flow path 1000W of the filler module 1000 as an air flow path and the first flow path 1000G as a shower water flow path.

[0239] In this way, the filling modules 1000 can be intentionally spaced apart when designing the cooling tower 3000, and the installation intervals 3999 can allow workers to enter during installation and maintenance of the filling modules 1000 to move and inspect the status of the filling modules 1000 with respect to each other.

[0240] In particular, during the installation of packing modules 1000, because the distance between packing modules 1000 is relatively long in the stacking direction, packing modules 1000 are typically stacked in sections to a predetermined thickness, forming individual packing modules 1000 units. These units are then aligned and positioned close together in the stacking direction to form a complete row of packing modules 1000. Therefore, during the installation of cooling tower 3000, to minimize air and water leakage, it is essential to ensure that the individual packing modules 1000 units are aligned during installation. However, when packing modules 1000 are installed without a 3999 mm spacing between each other in the horizontal direction, it is virtually impossible to adjust the vertical alignment of the individual packing modules 1000 units. Consequently, precise control of installation accuracy is required for each unit, leading to a need for improved installation efficiency.

[0241] In this regard, according to this use case, since installation gaps 3999 are provided between each other in the lateral direction of the packing modules 1000, when installing the modules of each packing module 1000 in the stacking direction, the operator can easily adjust the units of each packing module 1000 by using the installation gaps 3999. Even if a unit is damaged due to some special accident, the damaged unit can be disassembled, and the units before and after it can be easily moved to replace it, and a new unit can be added from the end of the packing module 1000 in the stacking direction to complete the repair.

[0242] When sealing plate 3998 is installed in mounting gap 3999, it is preferably removable or erected, rendering sealing plate 3998 ineffective. In this case, because second flow path 1000W is configured as an air flow path, a large amount of air flows only through mounting gap 3999. This significantly reduces the cooling efficiency of hot water, making it suitable for meeting special needs in factory production.

[0243] (Use Example 4)

[0244] 30 is a schematic diagram of Use Example 4. In this Use Example, similar to Use Example 3, spaces are provided between the filler modules 1000 in the lateral direction, but ordinary filler modules F are further provided to fill the spaces.

[0245] The conventional packing module F can be any existing packing module. For example, the most widely used packing module F is simply formed by stacking multiple packing sheets. In this case, there are no separated flow paths within the packing module F. Hot water is poured into the thin heat exchange space formed by each pair of adjacent packing sheets in the stacking direction from the top end. The fan of the cooling tower 4000 draws cold air into the packing module F from the bottom end opening, allowing direct contact between the air and the hot water for heat exchange.

[0246] As shown above, in this example, second flow path 1000W is preferably used as a hot water shower path, while first flow path 1000G is used as an air flow path. Thus, in this example, hot water is simultaneously supplied to second flow path 1000W and packing module F. The hot water flowing into packing module 1000 through its second upper end openings W1 and W2 exchanges heat with air drawn in through its second lower end opening G' within packing module 1000. Meanwhile, the hot water showered into packing module F directly contacts air drawn in through its lower end within packing module F, exchanging heat within the packing module.

[0247] Thus, the air discharged upward from the first upper end opening G of the filler module 1000 becomes hot air with low saturation, while the hot air flowing out from the upper end of the filler module F becomes saturated hot air.

[0248] On the other hand, due to the setting of the second upper end openings W1 and W2, the air resistance in the second flow path 1000W is very large, so the amount of air actually discharged upward from the second upper end opening W of the filling module 1000 is very small, which is very small compared to the amount of air passing through the filling module F.

[0249] Therefore, the low-saturation hot air discharged primarily from the first upper opening G of filler module 1000, the saturated hot air discharged from filler module F, and a very small amount of saturated hot air discharged from the second upper openings W1 / W2 of filler module 1000, are mixed above the filler module. This effectively utilizes the unsaturated hot air, reduces the saturation of the mixed air, and significantly improves the heat exchange efficiency of the cooling tower while ensuring sufficient demisting effect.

[0250] According to the packing module 1000 of this embodiment, by providing a first upper end opening G in the middle of the top width direction and providing second upper end openings W (W1, W2) on both sides of the first upper end opening G, the packing module 1000 can be used to build cooling towers 2000, 2100, 3000, 4000, etc., allowing for greater flexibility and flexible arrangement of air and hot water channels. In particular, when the first flow path 1000G connected to the first upper end opening G is used as the air flow path, the isolation between the air flow path and the hot water spray flow path is more complete. This can minimize the relative humidity of the air after heat exchange, thereby improving the defogging effect, which is particularly suitable for winter conditions in northern my country.

[0251] However, the filler module 1000 provided in this embodiment and the cooling tower having the filler module 1000 are not limited to the situation described in this embodiment.

[0252] In this embodiment, the filling module 1000 includes an upper guide portion 200G, 200W located in the upper section and a heat exchange portion 401, 402 thereunder, and an alternatingly stacked first flow path 1000G and a second flow path 1000W are formed by alternately overlapping filling 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.

[0253] The filler piece 1000A has a biasing portion 1100A in the middle of the upper guide portion, biased toward the front in the stacking direction, and biasing portions 1100B on both sides of the upper guide portion, biased toward the rear in the stacking direction. The filler piece 1000B has a biasing portion 1200A in the middle of the upper guide portion, biased toward the rear in the stacking direction, and biasing portions 1200B on both sides of the upper guide portion, biased toward the front in the stacking direction.

[0254] Thus, by stacking filler sheets 1000A and 1000B, offset portions 1100A and 1100B formed in the middle of the upper guide portion of filler sheets 1000A and 1000B form a first upper end opening G. Offset portions 1200A and 1200B formed on both sides of the upper guide portion of filler sheets 1000B and 1000A form a second upper end opening W.

[0255] In the first flow path 1000G, the first upper end opening G communicates with the first heat exchange portion 401 of the packing module 1000 over substantially the entire width. In the second flow path 1000W, the second upper end opening W communicates with the second heat exchange portion 402 of the packing module over substantially the entire width.

[0256] In this embodiment, a lower guide portion is further provided below the heat exchange portion. For the first and second flow paths 1000G and 1000W, the lower guide portion is constructed inversely of the first and second upper guide portions 200G and 200W, namely, it includes corresponding offset portions, and a first and second lower end opening formed therein, and further includes an inclined guide portion embedded in the guide portion including the offset portion, which obliquely connects the first and second lower end openings with the first and second heat exchange portions 401 and 402, thereby forming flow fins 1300G' and 1300W'. In this case, the flow fins 1300G' and 1300W' can be the same components as the flow fins 1300G and 1300W, simply inverted.

[0257] Rectifiers 1300G and 1300W are located in the upper guide section of packing module 1000. When directing hot water inflow, in particular, it is necessary to direct the hot shower water from the first upper opening G or the second upper opening W (W1, W2) in the middle of the width to the approximately full-width first heat exchange section 401 or second heat exchange section 402. Therefore, the lower ends of the guide grooves formed by the rectifiers are bent and gradually flattened to ensure uniform distribution of the guided fluid across the heat exchange surfaces of packing sheets 1000A and 1000B. However, for rectifiers 1300G" and 1300W", since they are located in the lower guide section, uniformity does not need to be considered when directing the shower water out of packing module 1000. Therefore, the flattened portions can be removed, retaining only the bent guide flow path. This can also prevent low-flow fluid, especially hot water for showers, from clogging after long-term use due to the accumulation of debris in the water caused by the narrowing of the flow path due to the flattened portions of the upper ends of the rectifiers 1300G' and 1300W' when flowing out of the packing module 1000.

[0258]

Packing assembly 5100

[0259] As previously mentioned, when installing the packing modules 1000, they are typically stacked in sections to a specified thickness (e.g., 1 to 3 meters) to form units of the packing modules 1000. These units are then arranged in a straight line and close to each other in the stacking direction of the packing modules 1000, forming a complete row of packing modules 1000. Therefore, during the installation and construction of the cooling tower 3000, in order to minimize air and water leakage, it is necessary to ensure that the units of the packing modules 1000 are aligned during installation. However, when installing the packing modules 1000 at the construction site, since the installation is done inside the cooling tower, manual labor is often required to position each packing module 1000, making the operation difficult. Furthermore, due to unavoidable factors such as tolerances and deformation of the packing modules 1000, the connecting surfaces between two adjacent packing modules 1000 in the stacking direction of the packing sheets cannot be tightly attached, which can easily lead to leakage. In cold winter, water leaking into the air flow path will form ice, causing blockage of the air flow path and even damage to the equipment.

[0260] To address the above issues, as shown in Figures 31 and 32 , this embodiment provides a packing assembly 5100, which includes a packing module 1000 and a packing frame 5110 surrounding the packing module. Furthermore, the length of the packing assembly 5100 in the packing sheet stacking direction is greater than its width. In actual engineering, the packing module 1000 can be manufactured in a factory, and the packing frame 5100 can be installed outside of the packing module.

[0261] For example, the length of the packing assembly 5100 in the direction of the stacking of the packing sheets is approximately equal to 1 / 2 of the length of the corresponding direction in the interior space of the cooling tower. Thus, as shown in Figures 33 and 34, the packing assembly 5100 and the packing assembly 5100' respectively occupy half of the length of the cooling tower in the corresponding direction. The packing assembly 5100 is installed into the cooling tower from the left side in Figure 34 using a lifting device or tool, and the packing assembly 5100' is installed into the cooling tower from the right side in Figure 34 using a lifting device or tool. By adopting the above method, when constructing a cooling tower, each packing assembly 5100, 5100' can be quickly installed into the interior of the cooling tower, which greatly improves the speed of installing the packing layer of the cooling tower and reduces the probability of leakage at the connection surface between the packing modules.

[0262] In some embodiments, the packing frame 5100 can be made of square tubes, angle irons, or other profiles through welding, screw connections, or other methods. The components forming the packing frame 5100 can be located at the corners of the packing module 1000. To enhance the strength of the packing frame 5100, at least one of horizontal, vertical, and inclined tie bars can be provided.

[0263] As shown in Figures 31 and 32, the filler assembly 5100 may further include an upper frame 5120, which is fixed to the upper side of the filler frame 5110. The upper frame 5120 can be used as a support structure for the spray system 5200, and the spray pipe 5210 of the spray system can be fixed on the top of the upper frame 5120, and the spray head 5220 can be installed at an appropriate position.

[0264] In addition, the above-mentioned upper frame 5120 can have a split structure, that is, the splits of multiple upper frames 5120 are assembled to form the upper frame 5120, and the upper frame 5120 is installed on the upper side of the filling frame 5110, which reduces the weight of a single split and facilitates transportation and assembly.

[0265] As shown in FIG33 , the packing frame 5110 and the upper frame 5120 can provide support for the installation of the partitions 2005 and 2005 ′ without having to construct additional beams in the cooling tower, thereby improving the convenience of installation and the sealing performance of the partitions 2005 and 2005 ′.

[0266] The above describes in detail the packing module of the preferred embodiment of the present invention and the cooling tower having the packing module, but those skilled in the art can make various modifications, changes, combinations, etc. on this basis, and these modifications, changes, and combinations all fall within the scope of protection of the claims of this application.
