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.
[0096] 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.
[0097] 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).
[0098] 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.
[0099] 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).
[0100] 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.
[0101] [Lower guide section 300]
[0102] 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.
[0103] 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.
[0104] 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.
[0105] 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.
[0106] 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.
[0107] 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.
[0108] 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.
[0109] 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.
[0110] [Unit of the first flow path R1]
[0111] 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 .
[0112] 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.
[0113] 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.
[0114] [Unit of the second flow path R2]
[0115] 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.
[0116] 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.
[0117] 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.
[0118] [Heat exchange unit 400]
[0119] 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.
[0120] [Upper and lower openings of the flow path]
[0121] 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.
[0122] 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).
[0123] 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).
[0124] 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.
[0125] 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 packing sheet A is offset toward the back side in the figure, while the left lower end of packing sheet B is offset toward the front side in the opposite figure, the left lower ends of packing sheets AB are affixed to each other, while the left lower ends of packing sheets BA are open to each other. As a result, the strip-shaped openings with the left lower ends of packing sheets BA open to each other are arranged side by side in the stacking direction through the affixed left lower ends of packing sheets AB, forming a complete first lower end opening 310. Without considering the thickness of the packing sheets, this is equivalent to forming an open first lower end opening 310 across the entire area of the lower end of packing module 1 perpendicular to the stacking direction (the left side in the figure).
[0126] 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).
[0127] [Opening of flow path]
[0128] The first flow path R1 will be described in further detail from top to bottom.
[0129] 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.
[0130] 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.
[0131] 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.
[0132] The second flow path R2 has a rotationally symmetrical structure with the first flow path R1, which will be described in detail below.
[0133] 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.
[0134] 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.
[0135] 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.
[0136] 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.
[0137]
Rectifier
[0138] 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.
[0139] 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.
[0140] 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.
[0141] 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.
[0142] 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.
[0143] 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.
[0144] [Second embodiment]
[0145] 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.
[0146] 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'.
[0147] 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'.
[0148] 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.
[0149] 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.
[0150] 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.
[0151] 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.
[0152] 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.
[0153] 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.
[0154] 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.
[0155] 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.
[0156] 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.
[0157] 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.
[0158] 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.
[0159] 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'.
[0160] 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.
[0161] [Third embodiment]
[0162] 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 .
[0163] 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.
[0164] 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.
[0165] 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.
[0166] 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 .
[0167] 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.
[0168] 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.
[0169] 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.
[0170] 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.
[0171] 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.
[0172] 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.
[0173] 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.
[0174] 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.
[0175] 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.
[0176] [Fourth embodiment]
[0177] 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.
[0178] 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.
[0179] 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.
[0180] 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.
[0181] 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 .
[0182] 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 .
[0183] 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 .
[0184] 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 .
[0185] 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.
[0186] 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 .
[0187] 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.
[0188]
Cooling Tower 1
[0189] FIG10 is a schematic diagram of a cooling tower manufactured based on the filler module 1 of this embodiment.
[0190] 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.
[0191] 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.
[0192] 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.
[0193] Working status 1:
[0194] 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.
[0195] 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.
[0196] 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.
[0197] 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.
[0198] 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.
[0199] 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.
[0200] Working status 2:
[0201] 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.
[0202]
Cooling Tower 20
[0203] 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.
[0204] 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.
[0205] Working status 1:
[0206] 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.
[0207] 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.
[0208] 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.
[0209] 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.
[0210] Working status 2:
[0211] 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.
[0212] 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.
[0213] 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 .
[0214] 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.
[0215] 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.
[0216] 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.
[0217] 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.
[0218] 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.
[0219] The flow straightening piece 240 located in the space of the upper right guide portion 202 has the same structure, except that the arrangement position is rotationally symmetrical with respect to the flow straightening piece 240 in the horizontal direction.
[0220] 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.
[0221] 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.
[0222] 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.
[0223] 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 made the same, the four upper left section guides 201, the upper right section guides 202, the lower left section guides 301, and the lower right section guides 302 can form a rotationally symmetrical structure, so that the rectifiers 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 sheet A, the filling sheet B and the universal rectifier sheet. 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 the rectifier sheets when assembling the filling sheet A, the filling sheet B and the rectifier sheet, making assembly convenient, thereby greatly reducing the overall production cost of the filling module 1.
[0224] 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.

Packing assembly 350
[0226] As previously mentioned, when installing the packing modules 1, the packing modules 1 are usually divided and stacked only to a specified thickness (e.g., 1 to 3 meters) to form units of the packing modules 1. Each unit is arranged in a straight line and close to each other in the stacking direction of the packing modules 1 to form a complete row of packing modules 1. Therefore, during the installation and construction of the cooling tower 30, in order to ensure that the cooling tower 30 has as little air and water leakage as possible, it is necessary to ensure that each unit of the packing modules 1 is in a straight line during installation. However, when installing the packing modules 1 at the construction site, since the construction is carried out inside the cooling tower, it is often necessary to manually place each packing module 1 in place, which is difficult to operate. In addition, unavoidable factors such as tolerance and deformation of the packing modules 1 result in the connection surfaces between two adjacent packing modules 1 in the stacking direction of the packing sheets not being tightly attached together, which is prone to leakage. In cold winters, water leaking into the air flow path will form ice, causing blockage of the air flow path and even damage to the equipment.
[0227] To address the above issues, as shown in Figures 17 and 18 , this embodiment provides a packing assembly 350 comprising a packing module 1 and a packing frame 351 surrounding the packing module. Furthermore, the length of the packing assembly 350 in the packing sheet stacking direction is greater than its width. In actual construction, the packing module 1 can be manufactured in a factory, and the packing frame 350 can be installed outside of the packing module.
[0228] For example, the length of the packing assembly 350 in the direction of the packing sheet stacking is approximately equal to 1 / 2 of the length of the corresponding direction in the internal space of the cooling tower. Therefore, as shown in Figures 19 and 20, the packing assembly 350 and the packing assembly 350' respectively occupy half of the length of the cooling tower in the corresponding direction. The packing assembly 350 is installed into the cooling tower from the left side in Figure 20 using a lifting device or tool, and the packing assembly 350' is installed into the cooling tower from the right side in Figure 20 using a lifting device or tool. Using the above method, when constructing a cooling tower, each packing assembly 350, 350' 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.
[0229] In some embodiments, the packing frame 350 can be made of square tubes, angle irons, or other profiles through welding, screw connections, or other methods. The components forming the packing frame 350 can be located at the corners of the packing module 1. To increase the strength of the packing frame 350, at least one of horizontal, vertical, and inclined tie bars 3511 can be provided.
[0230] As shown in Figures 17 and 18, the filler assembly 350 may further include an upper frame 352, which is fixed to the upper side of the filler frame 351. The upper frame 352 can be used as a support structure for the spraying portion 104, and the spray pipe 1042 of the spraying portion 104 can be fixed on the top of the upper frame 352, and the spray head 1041 can be installed at an appropriate position.
[0231] In addition, the upper frame 352 may have a split structure, that is, multiple upper frames 352 are assembled to form an upper frame 352, and the upper frame 352 is installed on the upper side of the filling frame 351, thereby reducing the weight of a single split and facilitating transportation and assembly.
[0232] As shown in FIG19 , the packing frame 351 and the upper frame 352 can provide support for the installation of the partitions 105 and 105 ′ without having to construct additional beams in the cooling tower, thereby improving the convenience of installation and the sealing performance of the partitions 105 and 105 ′.
[0233] 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.
