Description

Technical Field

[0001] This utility model relates to a cooling tower, specifically an anti-icing, water-saving, and fog-eliminating cooling tower. Background Technology

[0002] The cooling tower packing module separates the downward hot water flow path and the upward cold air flow path. Hot water flows in through an opening formed on a portion of the width of the upper part of the packing module, and an opening formed on another portion of the width of the upper part of the packing module for air to flow through.

[0003] However, in the aforementioned cooling towers with separated flow path packing modules, some areas inside the cooling tower, especially those near the tower wall, are prone to icing during cold winter weather. To solve this technical problem, this embodiment provides an anti-icing, water-saving, and anti-fogging cooling tower. Utility Model Content

[0004] In view of the above-mentioned prior art, the present invention provides an anti-icing, water-saving, and anti-fogging cooling tower, comprising:

[0005] The first and second packing modules are spaced apart.

[0006] The first packing module includes:

[0007] Multiple first and second packing sheets are alternately stacked. In the stacking direction, a first flow path is formed between the first and second packing sheets, and a second flow path is formed between the second and first packing sheets.

[0008] The second packing module consists of multiple packing sheets stacked together, forming only one flow path;

[0009] In the stacking direction, there is an end isolation zone between the first packing module and the inner surface of the tower wall of the anti-icing, water-saving, and fog-eliminating cooling tower, and the second packing module is filled in the end isolation zone.

[0010] In the defogging mode, the first flow path serves as the flow path for spray water, with spray water flowing in from the first upper opening and flowing out from the first lower opening; the second flow path serves as the flow path for air, with air flowing in from the second lower opening and flowing out from the second upper opening, so that in the first packing module, the air flowing in from below and the water sprayed from above exchange heat; the second packing module serves as the air flow path.

[0011] In the non-fogging mode, the first flow path and the second flow path of the first packing module, and the flow path of the second packing module, all serve as the flow paths for the spray water.

[0012] By setting up end isolation zones, a buffer area is created between the cooling tower wall and the spray space. Even if water droplets leak or splash out from the spray space, they will fall into the first and second end isolation zones and will not form wall flow and freeze on the inner surface of the cooling tower wall.

[0013] The heat exchange area in the non-fogging mode is further increased by filling the aforementioned end isolation zone with a second packing module.

[0014] The preferred embodiment of the present invention is an anti-icing, water-saving, and fog-eliminating cooling tower, characterized in that the first packing module has an upper bracket on its upper side and a lower bracket on its lower side, and the upper bracket, the packing module, and the lower bracket are connected by a tensioning assembly.

[0015] The packing assembly in this embodiment achieves modularity of the packing module through a lower bracket and an upper bracket. It only requires stacking the upper bracket, the packing module, and the lower bracket, which improves the efficiency of installation.

[0016] The preferred embodiment of this utility model of an anti-icing, water-saving, and fog-eliminating cooling tower is characterized in that, in the first packing module,

[0017] An upper partition area is formed between the first upper opening and the second upper opening. The upper bracket has an upper support portion corresponding to the upper partition area. A sealing strip is provided between the upper support portion and the upper partition area.

[0018] A lower partition area is formed between the first lower opening and the second lower opening. The lower bracket has a lower support portion corresponding to the lower partition area, and a sealing strip is provided between the lower support portion and the lower partition area.

[0019] The tensioning assembly can transfer the compressive force to the sealing strip through the lower and upper brackets, causing the sealing strip to deform and thus separating the openings on the left and right sides of the partition area.

[0020] The preferred embodiment of the present invention is an anti-icing, water-saving, and fog-eliminating cooling tower, characterized in that the upper support extends along the stacking direction, and the length of the upper support is the same as the stacking thickness of the first packing module.

[0021] The lower support extends along the stacking direction, and the length of the lower support is the same as the stacking thickness of the first filler module.

[0022] Multiple first packing modules are sequentially connected in the stacking direction to form a packing assembly.

[0023] The upper and lower support sections effectively separate the upper and lower partition areas, reducing the obstruction of the water and air flow paths. The sequential connection of the upper and lower support sections of different packing components enables rapid assembly, improving construction efficiency. Furthermore, this embodiment can effectively utilize the flow paths at the connection points of two adjacent packing components in the packing sheet stacking direction, increasing the heat exchange area.

[0024] The preferred embodiment of this utility model of an anti-icing, water-saving, and fog-eliminating cooling tower is characterized in that adjacent packing assemblies in the stacking direction are connected by horizontal tie rods, which is simple and reliable, facilitates the sequential connection of multiple packing assemblies, reduces the obstruction of the flow area, and provides tension force for the sealing of the connection.

[0025] The preferred embodiment of the present invention is an anti-icing, water-saving, and fog-eliminating cooling tower, characterized in that a baffle extending along the stacking direction is provided on the upper side of the packing assembly;

[0026] The lower end of the partition corresponds to the upper partition area;

[0027] Two end baffles are respectively provided at two ends near the inner surface of the tower wall in the stacking direction of the first packing module, connecting two adjacent baffles; the end isolation area is located between the end baffle and the inner surface of the tower wall. In this embodiment, the combination of end baffles and baffles encloses the spray space, which can effectively isolate the water in the spray space and prevent water from flowing into the air intake space and forming ice.

[0028] The preferred embodiment of the present invention is an anti-icing, water-saving, and fog-eliminating cooling tower, characterized in that the anti-icing, water-saving, and fog-eliminating cooling tower further includes a first spray manifold and a second spray manifold.

[0029] The first spray manifold is located above the first packing module and sprays water only into the first upper opening of the first packing module;

[0030] The second spray manifold is located above the second packing module and is used to spray water onto the second packing module and the second upper opening of the first packing module;

[0031] The second spray manifold is set to be closed in defogging mode and open in non-defogging mode.

[0032] In this embodiment, water is supplied to the spray space and the air intake space through the first spray manifold and the second spray manifold, respectively, which facilitates the rapid switching between the anti-fog mode and the non-anti-fog mode.

[0033] The preferred anti-icing, water-saving, and defogging cooling tower of this utility model is characterized in that a first rectifier plate is embedded in the upper section of the first flow path, which guides the width of the flow path from the width of the first upper opening to approximately the full width of the first packing module from top to bottom.

[0034] The first rectifier has multiple guide slots whose width gradually increases from top to bottom.

[0035] In this embodiment, the water is evenly distributed in the first flow path by the first rectifier plate, and the sheet-like, repeatedly folded structure reduces air resistance.

[0036] The preferred anti-icing, water-saving, and fog-eliminating cooling tower of this utility model is characterized in that, in the upper section of the second flow path, a second rectifier plate is embedded, which guides the width of the flow path from the width located on both sides of the first upper opening to approximately the full width of the first packing module.

[0037] The second rectifier has multiple guide slots whose width gradually increases from top to bottom.

[0038] In this embodiment, the water is evenly distributed in the second flow path by using the second rectifier plate, and the sheet-like, repeatedly folded structure reduces air resistance.

[0039] The preferred embodiment of this utility model of an anti-icing, water-saving, and defogging cooling tower is characterized in that the first packing module and the second packing module are alternately spaced in a direction perpendicular to the stacking direction; this increases the heat exchange area in the non-defogging mode during summer and reduces construction costs.

[0040] The anti-icing, water-saving, and fog-eliminating cooling tower of this invention effectively solves the icing problem in fog-eliminating mode while achieving water saving and fog elimination. Attached Figure Description

[0103] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0104] [First Implementation Method]

[0105] The filling module 1 of the first embodiment of this utility model will be described in detail below.

[0106]

Filling Module 1

[0107] In this embodiment, the packing module 1 includes packing sheets A and B that are alternately stacked at a predetermined interval d. The stacked packing sheets A and B form an alternately arranged first flow path R1 and second flow path R2 within the packing module 1.

[0108] An upper guide section 200 and a lower guide section 300 are formed in the upper and lower sections of the packing module 1, respectively, and a heat exchange section 400 is formed in the middle section.

[0109] [Introductory Section 200]

[0110] At the upper end of the upper guide section 200, the upper ends of rectangular packing pieces A and B are alternately arranged to form a guide opening, as detailed below.

[0111] On the side perpendicular to the stacking direction (left side in the figure), the upper end of packing sheet A is offset towards the stacking direction (back side in the figure), while the upper end of packing sheet B is offset towards the opposite direction (front side in the figure). This results in the upper left ends of packing sheets AB fitting together in the stacking direction from front to back, while the upper left ends of packing sheets BA are open to each other, forming a first upper opening 210. For packing module 1, multiple first upper openings 210 are arranged side-by-side in the stacking direction. Thus, this first upper opening 210 communicates with the first flow path R1 formed between the packing sheets BA.

[0112] On the other side perpendicular to the stacking direction (right side in the figure), the upper end of packing sheet A is offset towards the other side of the stacking direction (front side in the figure), while the upper end of packing sheet B is offset towards the opposite side (rear side in the figure). This results in the upper right ends of packing sheets BA fitting together in the stacking direction from front to rear, while the upper right ends of packing sheets AB are open to each other, forming a second upper opening 220. For packing module 1, multiple second upper openings 220 are arranged side-by-side in the stacking direction. Thus, the first upper opening 220 communicates with the first flow path R2 formed between packing sheets AB.

[0113] In the upper guide section 200, a left upper path rectifier 230 is embedded in the first flow path R1 between the first upper opening 210 formed by the packing sheet BA and the heat exchange section 400 surrounded by the packing sheet BA. The upper end of the left upper path rectifier 230 matches the width of the first upper opening 210, and the width gradually increases from top to bottom, while the lower end corresponds to the width of the heat exchange section 400 (the first heat exchange section 401 of the first flow path).

[0114] In this embodiment, the left upper rectifier plate 230 has a bent cross-section along the transverse direction perpendicular to the stacking direction. The two sides of the bent stacking direction, i.e., the back side, abut against the front surface of the packing plate A that holds it, and the front side abuts against the rear surface of the packing plate B that holds it. Thus, in the first flow path R1, which is approximately a right-angled trapezoid formed between the first upper opening 210 and the heat exchange section 400, a guide portion is formed that guides the width of the first upper opening 210 to the full width of the heat exchange section 400, which is approximately the width of the packing plates A and B.

[0115] In the upper guide section 200, a right upper path rectifier 240 is embedded in the second flow path R2 between the second upper opening 220 formed by the packing sheet AB and the heat exchange section 400 surrounded by the packing sheet AB. The upper end of the right upper path rectifier 240 matches the width of the second upper opening 220, and the width gradually increases from top to bottom, while the lower end corresponds to the width of the heat exchange section 400 (the first heat exchange section 402 of the second flow path).

[0116] In this embodiment, the right upper rectifier plate 240 has a bent cross-section along the transverse direction perpendicular to the stacking direction. The two sides of the bent stacking direction, i.e., the back side, abut against the front surface of the packing plate B that holds it, and the front side abuts against the rear surface of the packing plate A that holds it. Thus, in the second flow path R2, which is approximately a right-angled trapezoid formed between the second upper opening 220 and the heat exchange section 400, a guide portion is formed that guides from the width of the second upper opening 220 to the full width of the heat exchange section 400, which is approximately the width of the packing plates A and B.

[0117] [Next section guide 300]

[0118] At the lower end of the lower guide section 300, the lower ends of packing pieces A and B are alternately arranged to form a guide opening, as detailed below.

[0119] On the side perpendicular to the stacking direction (left side in the figure), the lower end of packing sheet A is offset towards the stacking direction (back side in the figure), while the lower end of packing sheet B is offset towards the opposite direction (front side in the figure). This results in the lower left ends of packing sheets A and B being close together in the stacking direction from front to back, while the lower left ends of packing sheets B and C are open to each other, forming a first lower opening 310. Thus, this first lower opening 310 communicates with the first flow path R1 formed between the packing sheets B and C.

[0120] On one side perpendicular to the stacking direction (right side in the figure), the lower end of packing sheet A is offset towards the other side of the stacking direction (front side in the figure), while the lower end of packing sheet B is offset towards the opposite side (rear side in the figure). This results in the lower left ends of packing sheets BA being in contact with each other along the stacking direction from front to rear, while the lower left ends of packing sheets AB are open to each other, forming a second lower opening 320. Thus, this first lower opening 320 communicates with the first flow path R2 formed between the packing sheets AB.

[0121] In the lower guide section 300, a left lower rectifier plate 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 rectifier plate 330 matches the width of the first lower opening 310, and the width gradually increases from bottom to top, while the upper end corresponds to the width of the heat exchange section 400.

[0122] In this embodiment, the lower left rectifier plate 330 has a bent cross-section along the transverse direction perpendicular to the stacking direction. The bent back side abuts against the front surface of packing plate A, and the front side abuts against the rear surface of packing plate B. Thus, within the first flow path R1, which is approximately an inverted right-angled trapezoid formed between the first lower opening 310 and the heat exchange section 400, a guide portion is formed that guides the width of the first lower opening 310 to the full width of the heat exchange section 400, which is approximately the width of the packing plates A and B.

[0123] In the lower guide section 300, a right lower rectifier plate 340 is embedded in the second flow path R2 between the second lower opening 320 formed by the packing sheet AB and the heat exchange section 400 surrounded by the packing sheet AB. The lower end of the right lower rectifier plate 340 matches the width of the second lower opening 320, and the width gradually increases from top to bottom, corresponding to the width of the heat exchange section 400.

[0124] In this embodiment, the right lower rectifier plate 340 has a bent cross-section along the transverse direction perpendicular to the stacking direction. The bent back side abuts against the front surface of the packing plate B, and the front side abuts against the rear surface of the packing plate A. Thus, within the second flow path R2, which is approximately an inverted right-angled trapezoid formed between the second lower opening 320 and the heat exchange section 400, a guide portion is formed that guides from the width of the second lower opening 320 to the full width of the heat exchange section 400, which is approximately the width of the packing plates A and B.

[0125] A packing module 1 is formed by alternately stacking packing sheets A and B, and within the packing module 1, a first flow path R1 and a second flow path R2 are formed, which are isolated from each other and alternately stacked. The configuration of the first flow path R1 and the second flow path R2 will be described in detail below.

[0126] [Units of the first flow path R1]

[0127] In this embodiment, for the packing module 1, in the stacking direction from the front to the rear in the figure, the unit that forms the first flow path R1 between the adjacent packing sheet B and the packing sheet A located behind the packing sheet B, i.e., the packing sheet BA.

[0128] As shown in the figure, the first flow path R1 includes, from top to bottom, a first upper opening 210 located on the left side of the upper end of the packing module 1; a left upper guide section 201 located in the upper guide section 200, filled and supported between packing plates B and A by the left upper rectifier plate 230; a first heat exchange section 401 with a flat cavity formed between packing plates BA in the stacking direction at the heat exchange section 400; a left lower guide section 301 located in the lower guide section 300, filled and supported between packing plates B and A by the left lower rectifier plate 330; and a first lower opening 310 located on the left side of the lower end of the packing module 1.

[0129] Therefore, in this embodiment, a unit of the first flow path R1, which forms a flat cavity between adjacent packing sheet B and packing sheet A, has a first upper opening 210, which is its upper opening, and a first lower opening 310, which is its lower opening, located on the same side perpendicular to the stacking direction.

[0130] [Units of the second flow path R2]

[0131] In this embodiment, for the packing module 1, in the stacking direction from the front to the rear in the figure, the unit that forms the second flow path R2 between the adjacent packing sheet A and the packing sheet B located behind the packing sheet A, i.e., the packing sheet AB.

[0132] As shown in the figure, the second flow path R2 includes, from top to bottom, a second upper opening 220 located on the right side of the upper end of the packing module 1; an upper right guide section 202 located in the upper guide section 200, filled and supported by the upper right rectifier plate 240 between packing plates A and B; a second heat exchange section 402 with a flat cavity formed between packing plates A and B in the stacking direction at the heat exchange section 400; a lower right guide section 302 located in the lower guide section 300, filled and supported by the lower right rectifier plate 340 between packing plates A and B; and a second lower opening 320 located on the right side of the lower end of the packing module 1.

[0133] Therefore, in this embodiment, a unit of the first flow path R1, which forms a flat cavity between adjacent packing sheet A and packing sheet B, has a second upper opening 220, which is its upper opening, and a second lower opening 320, which is its lower opening, located on the same side perpendicular to the stacking direction.

[0134] Heat Exchanger 400

[0135] The first heat exchange section 401 and the second heat exchange section 402 are alternately stacked to form a heat exchange section 400 in which the first flow path R1 and the second flow path R2 are alternately stacked and exchange heat at intervals.

[0136] [Openings at the top and bottom of the flow path]

[0137] As described above, in the stacking direction of packing sheets A and B, a first flow path R1 and a second flow path R2 are formed between packing sheets BA and AB, respectively, forming flat cavities, thereby alternating the stacking of the first flow path R1 and the second flow path R2. Thus, for packing module 1, first and second upper openings 210 and 220 are formed at the upper edge, perpendicular to the stacking direction.

[0138] In this embodiment, as shown in the figure, the first upper opening 210 is formed on the left side. Since the upper left end of packing sheet A is offset towards the back side in the figure, and the upper left end of packing sheet B is offset towards the front side in the opposite direction in the figure, the upper left ends of packing sheets AB are attached to each other, while the upper left ends of packing sheet BA are open to each other. Thus, the strip-shaped openings with the upper left ends of packing sheets BA open to each other are arranged side by side in the stacking direction through the attached upper left ends of packing sheets AB, forming a complete first upper opening 210. Without considering the thickness of the packing sheets, it is equivalent to forming the entire open first upper opening 210 in the entire area of ​​the upper end of the packing module 1 on the side perpendicular to the stacking direction (left side in the figure).

[0139] Similarly, the second upper opening 220 is formed on the right side. Opposite to the first upper opening 210, the upper right end of packing piece B is offset towards the back side in the figure, while the upper right end of packing piece A is offset towards the front side in the opposite direction in the figure. Therefore, the upper right ends of packing pieces BA are attached to each other, while the upper right ends of packing pieces AB are open to each other. This forms a strip-shaped opening with the upper right ends of packing pieces AB open to each other, arranged side-by-side in the stacking direction via the attached upper right ends of packing pieces BA, forming a complete second upper opening 220. Without considering the thickness of the packing pieces, this is equivalent to forming an open second upper opening 220 in the entire area of ​​the upper end of the packing module 1 on the other side (right side in the figure) perpendicular to the stacking direction.

[0140] On the other hand, first and second upper openings 210 and 220 are formed at the lower edge in parallel directions perpendicular to the stacking direction.

[0141] In this embodiment, as shown in the figure, the first lower opening 310 is formed on the left side. Since the lower left end of packing sheet A is offset towards the back side in the figure, and the lower left end of packing sheet B is offset towards the front side in the opposite direction in the figure, the lower left ends of packing sheets AB are attached to each other, while the lower left ends of packing sheet BA are open to each other. Thus, the strip-shaped openings with the lower left ends of packing sheets BA open to each other are arranged side by side in the stacking direction through the attached lower left ends of packing sheets AB, forming a complete first lower opening 310. Without considering the thickness of the packing sheets, it is equivalent to forming the entire open first lower opening 310 in the entire area of ​​the lower end of the packing module 1 on the side perpendicular to the stacking direction (left side in the figure).

[0142] Similarly, the second lower opening 320 is formed on the right side. Opposite to the first lower opening 310, the lower right end of packing piece B is offset towards the back side in the figure, while the lower right end of packing piece A is offset towards the front side in the opposite direction in the figure. Therefore, the lower right ends of packing pieces BA are attached to each other, while the lower right ends of packing pieces AB are open to each other. This creates a strip-shaped opening with the lower right ends of packing pieces AB open to each other, which, through the attached lower right ends of packing pieces BA, are arranged side-by-side in the stacking direction, forming a complete second lower opening 320. Without considering the thickness of the packing pieces, this is equivalent to forming an open second lower opening 320 in the entire area of ​​the lower end of the packing module 1 on the other side (right side in the figure) perpendicular to the stacking direction.

[0143] [Opening of the flow path]

[0144] The first flow path R1 will be further described in detail from top to bottom.

[0145] As described above, the first flow path R1 forms a first upper opening 210 at the upper end of the packing module 1, which is equivalent to forming a first upper opening 210 in the entire left area perpendicular to the stacking direction. At the first upper opening 210, the portion where the upper left ends of the packing sheets AB are attached to each other is divided into multiple units. After passing downward through the portion where the upper left ends of the packing sheets AB are attached to each other in the upper left guide section 201, the units of the first flow path R1 separate from each other in the stacking direction. On the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases in the direction perpendicular to the stacking direction to approximately the width of the packing sheets A and B, forming a flat shape, that is, the thickness decreases and the width increases. The units of the first heat exchange section 401 enter the flat heat exchange space defined by the packing sheet BA from the upper guide section 200.

[0146] As the heat exchange section 400 continues downward 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 descends from a flat shape roughly the width of the packing sheets A and B, gradually increasing in size in the stacking direction and gradually decreasing in size perpendicular to the stacking direction to the width of the second lower opening 220, that is, the thickness increases and the width decreases, and at the lower left guide section 301, the parts where the lower left ends of the packing sheets AB adhere to each other converge to reach the first lower opening 310.

[0147] Therefore, in the first flow path R1, the cross-sectional area of ​​the entire flow path from the first upper opening 210 through the upper guide section 200, the heat exchange section 400, the lower guide section 300, and down to the first lower opening 310, theoretically remains roughly unchanged.

[0148] The second flow path R2 is rotationally symmetrical to the first flow path R1, which will be explained in more detail below.

[0149] As described above, the second flow path R2 forms a second upper opening 210 at the upper end of the packing module 1, which is equivalent to forming a second upper opening 210 in the entire right-side region perpendicular to the stacking direction. At the second upper opening 210, the portion where the upper right ends of the packing sheets BA are attached to each other is divided into multiple units. After passing downward through the portion where the upper right ends of the packing sheets BA are attached to each other in the upper right guide section 202, the units of the first flow path R1 separate from each other in the stacking direction. On the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases in the direction perpendicular to the stacking direction to approximately the width of the packing sheets A and B, forming a flat shape, that is, the thickness decreases and the width increases. The units of the second heat exchange section 402 enter the flat heat exchange space defined by the packing sheets AB from the upper guide section 200.

[0150] As the heat exchange section 400 continues downward 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 descends from a flat shape roughly the width of the packing sheets A and B. On the one hand, the size gradually increases in the stacking direction, and on the other hand, the size gradually decreases in the direction perpendicular to the stacking direction to the width of the second lower opening 220. That is, the thickness increases and the width decreases. In the lower right guide section 302, the packing sheets BA converge at the part where the lower right ends of the packing sheets BA are attached to each other and reach the second lower opening 320.

[0151] Therefore, in the second flow path R2, the cross-sectional area of ​​the entire flow path from the second upper opening 220 through the upper guide section 200, the heat exchange section 400, the lower guide section 300, and down to the second lower opening 320, theoretically remains roughly unchanged.

[0152] As described above, in this embodiment, the sum of the opening areas of the first and second upper openings 210 and 220, which are the upper openings of the first and second flow paths R1 and R2, is consistent with the sum of the cross-sectional areas of the flow paths from top to bottom. Similarly, the sum of the opening areas of the first and second lower openings 310 and 320, which are the lower openings of the first and second flow paths R1 and R2, is consistent with the sum of the cross-sectional areas of the flow paths from top to bottom. That is, the opening areas at the upper and lower ends of the packing module 1 are consistent with the horizontal cross-sectional area of ​​the packing module 1, thereby greatly improving the fluid throughput and efficiency of each flow path R1 and R2 and reducing the resistance of the packing module 1. This will be explained in more detail later.

[0153] Rectifier chip

[0154] Thus, when rectifiers 230, 240, 330, and 340 are embedded in the guide sections 201, 202, 301, and 302, that is, when rectifiers 230, 240, 330, and 340 are embedded into their respective first and second flow paths R1 and R2, since each rectifier 230, 240, 330, and 340 is formed in a bent shape, and the extension direction of the bent ridge corresponds to the extension path of the first and second flow paths R1 and R2, respectively, and the thickness of each rectifier 230, 240, 330, and 340 is much different from the flow path cross-sectional area of ​​the first and second flow paths R1 and R2, it will not affect the throughput efficiency of the first and second flow paths R1 and R2.

[0155] Furthermore, in this embodiment, the first upper opening 210 and the second upper opening 220, which are the upper openings of the first and second flow paths R1 and R2, are arranged side by side perpendicular to the stacking direction and have approximately the same width. Thus, the upper left rectifier 230 and the upper right rectifier 240, which are located in the upper left guide section 201 and the upper right guide section 202 respectively, have approximately the same housing space configuration and are arranged in a rotationally symmetrical manner. Therefore, the same components can be used to construct the upper left rectifier 230 and the upper right rectifier 240.

[0156] Similarly, the first lower opening 310 and the second lower opening 320, which are the lower openings of the first and second flow paths R1 and R2, are arranged side by side perpendicular to the stacking direction and have approximately the same width. Thus, the lower left rectifier 330 and the lower right rectifier 340, which are located in the lower left guide section 301 and the lower right guide section 302 respectively, have approximately the same housing space configuration and are arranged in a rotationally symmetrical manner. Therefore, the same components can be used to construct the lower left rectifier 330 and the lower right rectifier 340.

[0157] Furthermore, in this embodiment, by making the heights of the upper guide section 200 and the lower guide section 300 approximately the same, the configuration of the receiving space for each rectifier segment 230, 240, 330, and 340 is approximately the same. This allows the same components to be used to construct the upper left rectifier segment 230, upper right rectifier segment 240, lower left rectifier segment 330, and lower right rectifier segment 340. Thus, when manufacturing the filler module 1, only filler sheet A, filler sheet B, and the shared rectifier segments are needed, significantly reducing the production cost of the filler module 1 and significantly improving assembly efficiency.

[0158] In this embodiment, the same packing sheet A and packing sheet B as in the first embodiment can be used. In the first embodiment, a left upper rectifier 230, a right upper rectifier 240, a left lower rectifier 330, and a right lower rectifier 340 are respectively provided for the upper left guide section 201, the upper right guide section 202, the lower left guide section 301, and the lower right guide section 302. The upper left guide section 201 and the lower left guide section 301 are both located on the same side of the packing module 1 (the left side in the first embodiment), and the upper right guide section 202 and the lower right guide section 302 are both located on the other side of the packing module 1 (the right side in the first embodiment). That is, fluid flowing into / introducing into the packing module 1 from one side (left side) of the width direction of the packing module 1 forms a flow path R1 of approximately the full width of the packing module 1 in the heat exchange section 400; while fluid flowing into / introducing into the packing module 1 from the other side (right side) of the width direction of the packing module 1 forms a flow path R2 of approximately the full width of the packing module 1 in the heat exchange section 400. The thickness of R1 and R2 in the stacking direction is half the thickness of each opening in the stacking direction, and the sum of the thicknesses of R1 and R2 is equivalent to half the thickness of the packing module 1 in the stacking direction. Therefore, a flow-in / out state is formed on the same side. That is, if hot water flows in from the first upper opening 210 on the upper left, the packing module 1 flows out from the first lower opening 310 on the lower left. If cold air is introduced from the first lower opening 310 on the lower left, the packing module 1 flows out from the first upper opening 210 on the upper left, forming the first flow path R1. The same applies to the second upper opening 220 and the second lower opening 320 on the right, 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 the same as the previous packing module, with hot water being poured into each of the first and second upper openings 210 and 220 at the same time, and cold air being drawn in from the first and second lower openings 310 and 320 at the same time, forming a flow path in which hot water and cold air directly contact each other in opposite directions for heat exchange. However, it is not possible to make the first flow path R1 and the second flow path R2 flow into different fluids as mentioned above, so that the discharged hot air after heat exchange has low saturated humidity to avoid fogging.

[0159] Of course, the first upper opening 210 and the first lower opening 310, which are the upper and lower openings of the first flow path R1, can also be respectively provided on different sides of the packing module; similarly, the second upper opening 220 and the second lower opening 320, which are the upper and lower openings of the second flow path R2, are also respectively provided on different sides of the packing module. This has no substantial impact on the function of the packing module 1 having two flow paths R1 and R2 separated by packing sheets A and B, as well as the openings at the upper and lower ends, and is an equivalent embodiment to the first embodiment described above.

[0160] [Second Implementation Method]

[0161] The packing module 1', a preferred embodiment of this utility model, differs from the packing module 1 of the first embodiment in that it only provides rectifiers in the first flow path R1, specifically an upper left rectifier 230 in the upper left guide section 201 of the first flow path R1 and a lower left rectifier 330 in the lower left guide section 301 of the first flow path R1. No rectifiers are provided in the second flow path R2. Therefore, in this embodiment, the first flow path R1 is used as a water spraying channel, while the second flow path R2 is used as an air intake channel.

[0162] like Figures 10-12 As shown, by providing rectifier plates 230 and 330 only in the first flow path R1, the spray water flowing into the packing module 1' from the first upper opening 210 arranged along the stacking direction (left of the arrow in the diagram), i.e., a portion of the width of the upper opening, is guided by the rectifier plate 230 within the upper left guide section 201 to approximately the full width of the first heat exchange section 401, effectively forming a water film on the walls of the packing plates A and B on both sides of the first flow path R1. Then, the water is guided by the rectifier plate 330 within the lower left guide section 301 to the first lower opening 310 arranged along the stacking direction (left of the arrow in the diagram), and flows out from a portion of the width of the lower opening of the packing module 1'.

[0163] On the other hand, cold air introduced into the packing module 1' via the second flow path R2 from the second lower opening 320 (a portion of the width of the lower opening) arranged along the stacking direction to the right of the arrow in the diagram, enters the lower right guide section 302. Due to the inherent flow properties of the gas fluid, 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. This effectively allows heat exchange between the hot water adhering to the wall of the first heat exchange section 401 and the packing sheets A and B. Then, in the upper right guide section 202, the width of the flow path is gradually restricted to a portion of the width of the second upper opening 220 (a portion of the width of the upper opening) arranged along the stacking direction, and the thickness of the flow path in the stacking direction is gradually expanded to 2d before exiting from the second upper opening of the packing module 1'.

[0164] As can be seen, compared with the packing module 1 of the first embodiment of this utility model, by removing the rectifiers in the upper right guide section 202 and the lower right guide section 302 of the second flow path R2 in this embodiment, and using the second flow path R2 only as a cold air flow path, the cold air drawn into the second flow path R2 can obtain the lowest possible wind resistance. Furthermore, since air flow is not affected by gravity as water flow, even without rectifiers, while ensuring the same airflow through the second flow path R2 as in the first embodiment, approximately the same cooling efficiency as the packing module 1 of the first embodiment can be obtained. However, since there are no rectifiers in the second flow path R2, the wind resistance of the air introduced into the packing module 1' is even lower. When using an active exhaust cooling tower, the power required by the fan at the top of the cooling tower is lower, effectively saving energy. Moreover, since the packing module 1' in this embodiment can obtain lower wind resistance, it is more suitable for cooling towers such as hyperbolic cooling towers that do not have fans and use a passive air intake method.

[0165] In this embodiment, preferably, the upper and lower openings of the first flow path R1 and the second flow path R2 are located on the same side in the width direction of the packing module. This allows for the formation of a good water-proof structure by arranging the packing plates A and B, preventing water in the first flow path R1, which has the upper left rectifier plate 230 and the lower left rectifier plate 330, from intruding into the air flow path of the second flow path R2 through the gaps. This will be explained in detail below.

[0166] Furthermore, in this embodiment, such as Figure 11 As shown, the upper end of the packing sheet A of the packing module 1' is located on the left side of the portion where the first upper opening 210 and the second upper opening 220 connect, i.e., on the side of the first upper opening 210, from the base position O of the heat exchange section 400 of the packing sheet A. A The rear half of the first upper opening 210, formed by the packing sheet A, is formed by offsetting it backward by a distance d / 2. Furthermore, a portion offset forward by a distance d from the rear half of the first upper opening 210, i.e., from the base position O of the heat exchange section 400 of the packing sheet A, is formed at the left edge of the packing sheet A. A The left sealing edge 215A is formed by offsetting forward by d / 2. The left sealing edge 215A extends in a straight line in the vertical direction.

[0167] Furthermore, at the upper end of the packing sheet A, on the right side of the portion where the first upper opening 210 and the second upper opening 220 connect, i.e. on the side of the second upper opening 220, it is offset forward by a distance d / 2 to form the front half of the second upper opening 210 of the second flow path R2 on the rear side formed by the packing sheet A.

[0168] Furthermore, at the upper end of the packing sheet B adjacent to the packing sheet A in the stacking direction, on the left side of the portion where the first upper opening 210 and the second upper opening 220 connect, i.e., on the side of the first upper opening 210, from the base position O of the heat exchange section 400 of the packing sheet B. B The first upper opening 210, formed by the packing plate B, is formed by offsetting forward by a distance d / 2. Furthermore, a rearward offset distance d is formed at the left edge of the packing plate B from the first upper opening 210, that is, from the base position O of the heat exchange section 400 of the packing plate B. B The left sealing portion 215B is formed at a rearward offset of d / 2. The left sealing portion 215B extends in a straight line in the vertical direction.

[0169] Furthermore, at the upper end of the packing sheet B, on the right side of the portion where the first upper opening 210 and the second upper opening 220 connect, i.e., on the side of the second upper opening 220, it is offset backward by a distance of d / 2 to form the rear half of the second upper opening 210 of the second flow path R2 on the front side formed by the packing sheet B.

[0170] Therefore, when packing sheet A and its adjacent packing sheet B are assembled in contact with each other, the upper edge of the left side portion of packing sheet A and packing sheet B, the rear half of the first upper opening 210 of packing sheet A and the front half of the first upper opening 210 of the adjacent packing sheet B form a complete first upper opening 210, and on the left side of the first upper opening 210, the left sealing edge portion 215A of packing sheet A and the left sealing edge portion 215B of packing sheet B come together from top to bottom.

[0171] Therefore, the first flow path R1, formed by packing sheet A and its adjacent front packing sheet B, has a 2d-thickness inlet, namely the first upper opening 210, and its left sealing edge 215 is formed by the combination of left sealing edge portion 215A and left sealing edge portion 215B, which are offset from each other and joined together. Its left sealing edge 215 can easily form a sealing structure during joint sealing. When this first flow path R1 is used as a hot water spray flow path, since hot water is sprayed in from the front and rear arranged first upper opening 210 located on the left side of the packing module 1', hot water is less likely to seep out from the left sealing edge 215 when guided into the heat exchange section 400.

[0172] On the other hand, after hot water is guided from the first upper opening 210 to the heat exchange section 400, the water flows along the rear wall of the packing sheet B and the front wall of the packing sheet A within the heat exchange section 400 under its own gravity, and will not easily intrude into the right sealing edge of the packing module 1'. Therefore, the sealing requirements for the right sealing edge are significantly reduced.

[0173] Specifically, in this embodiment, if the lower guide section 300 is rotated 180° about a horizontal axis perpendicular to the stacking direction, its structure is the same as that of the upper guide section 200. Similar to the upper guide section 200, the lower edge of the packing sheet A and its adjacent front packing sheet B is offset, thereby forming continuous left sealing edges 215A and 215B from top to bottom on the left edges of the packing sheets A and B, including the left edge of the heat exchange section 400. This effectively prevents water from seeping out from the left sealing edge 215, especially preventing water from seeping out from the left sealing edge 215 in the upper guide section 200 and the lower guide section 300.

[0174] Therefore, in this embodiment, any joining method can be used for the sealing portion 215 formed by the left sealing portions 215A and 215B. However, from the perspective of assembly convenience, it is preferable to join the sealing portion 210 by pressure welding. This is because when assembling the packing sheets A and B and the rectifier plates 230 and 330 using the equipment, simply aligning the adjacent packing sheets B in the front-to-back direction will cause the packing sheets A and B to be offset to each other on the right side of their upper and lower edges. Therefore, in this state, the welding operation of the packing sheet BA can be completed by operating the pressure welding equipment to weld the sealing portion 215 and the right side of the upper and lower edges of the packing sheet BA.

[0175] By inserting rectifier plates 230 and 330 between the packing sheets BA and welding the sealing portion 215 and the right side of the upper and lower edges of the packing sheets BA, the packing sheets BA in the stacking direction can form a module with very high structural stability. Then, the modules formed by multiple packing sheets BA are combined and glued together in the stacking direction. Because the individual modules have good strength and stability, the difficulty of module assembly can be greatly reduced, and the efficiency of assembling the packing sheet BA modules into packing module 1' can be improved.

[0176] In the accompanying drawings of this embodiment, for ease of assembly and processing, the right-side sealing edge is not fitted with the same structure as the left-side sealing edge 215. However, this does not constitute a limitation on the construction of the right-side sealing edge; of course, the right-side sealing edge can also be fitted with the same structure as the left-side sealing edge 215.

[0177] [Third Implementation Method]

[0178] As a preferred embodiment of the present invention, the filling module 1”, such as Figure 13 , 14As shown, the difference from the packing module 1 of the first embodiment is the configuration and assembly method of the upper left rectifier 230, upper right rectifier 240, lower left rectifier 330, lower right rectifier 340 and their respective first upper opening 210, second upper opening 220, first lower opening 310 and second lower opening 320.

[0179] In this embodiment, the upper edges of the upper left rectifier 230 and the upper right rectifier 240 are respectively lower than the first upper opening 210 and the second upper opening 220, that is, the upper edges of the upper left rectifier 230 and the upper right rectifier 240 are respectively located inside the first upper opening 210 and the second upper opening 220.

[0180] Similarly, the upper edges of the lower left rectifier 330 and the lower right rectifier 340 are respectively higher than the first lower opening 310 and the second lower opening 320, that is, the lower edges of the lower left rectifier 330 and the lower right rectifier 340 are respectively located inside the first lower opening 310 and the second lower opening 320.

[0181] In other words, in this embodiment, the open-side ends of the rectifier segments 230, 240, 330, and 340 are respectively located at a predetermined distance h inside the corresponding upper and lower openings 210, 220, 310, and 320. Figure 13 , 14 The example shown is only the upper left rectifier 230, while the other rectifiers 240, 330 and 340 can be set in the same way.

[0182] When packing sheets A and B are stacked, at the upper left guide section 201, because packing sheet A is offset to the rear side in the stacking direction and packing sheet B is offset to the front side in the stacking direction, the upper left edges of the two are brought together at the edge of the first upper opening 210.

[0183] Because the rectifier 230 embedded in the upper left guide section 201 is located inside the first upper opening 210, it avoids the upper edge of the filler sheet AB in the stacking direction at the first upper opening 210 and maintains a distance of h. Therefore, the avoidance area can be welded using a heating fixture to form a welding trajectory L.

[0184] In the first and second embodiments, the rectifier 230 is not retracted into the first upper opening 210. During welding, due to the interference of the rectifier arranged in a bent manner on the end face of the first upper opening 210, the weld can only adapt to the bending of the rectifier 230, forming an intermittent weld. As for the upper left edge of the filler AB, it can only be sealed by applying glue after being closed.

[0185] In contrast, in this embodiment, by retracting the rectifier plate into the first upper opening 210, the clearance area can be used to perform continuous pressure welding on the upper left edge of the packing sheet AB.

[0186] In this way, the connection strength of the upper left edge of the packing sheet AB is improved, and the overall strength of the packing module 1” can be significantly improved after multiple layers of packing sheets A and B are stacked.

[0187] On the other hand, and more importantly, when the first flow path R1 on the left is used as a hot water spray flow path and the second flow path R2 on the right is used as an air flow path, the inner side of the upper left joint of the packing sheet AB forming the first upper opening 210 is connected to the second flow path R2. By welding this joint, the watertight performance can be effectively improved, and leakage caused by delamination due to aging over the years can be avoided.

[0188] Furthermore, in this embodiment, by making the first lower opening also located on the left side of the packing module 1” as shown in the second embodiment, and forming continuous sealing portions 215A and 215B on the left edges of the packing sheet A and the packing sheet B respectively, the probability of the first flow path R1 leaking into the second flow path at the upper end when it is used as a hot water spray flow path can be minimized; the left side can also be sealed by welding to prevent leakage.

[0189] As for the right side, since the first flow path R1 guides the hot water from a portion of the width on the left side to approximately the full width of the heat exchange section, and then back to a portion of the width on the left side to flow out from the first lower opening 310, the hot water is difficult to overflow from the right edge under the action of gravity. Therefore, the right side sealing edge can be made by simple convex-concave joint method for interlocking, bonding, spot welding, etc.

[0190] Of course, without considering the slight increase in cost, the right-side sealing edge can be sealed in the same way as the left-side sealing edge. Alternatively, the right-side sealing edge can be formed by offsetting the right edge of the heat exchange section 400 of packing sheets A and B in the same direction as the left edge. This allows for complete sealing of the first flow path.

[0191] In this embodiment, as an example, only the configuration of the upper left rectifier 230 and the first upper opening 210 in the upper left guide section 201 is described. The same configuration can also be used for the other second upper opening 220, first lower opening 310, second lower opening 320, and the corresponding rectifiers 240, 330, and 340. This improves the overall strength of the packing module 1”, especially for the upper and lower end faces of the packing module 1” with the parallel upper and lower openings 210, 220, 310, and 320, where the strength is significantly enhanced. This greatly improves the robustness, reliability, and durability of the packing module 1” during transportation, handling, installation, and daily operation.

[0192] [Fourth Implementation Method]

[0193] In the first embodiment, the first upper opening 210 and the first lower opening 310 can both be located on the left side of the packing module and have the same width, and the second upper opening 220 and the second lower opening 320 can both 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 have identical components, reducing the manufacturing cost of the packing module. In other words, packing sheet B (i.e., the flipped packing sheet A) can be rotated 180° relative to the horizontal axis relative to packing sheet A. Therefore, in this embodiment, the description of packing sheet B is based on the position of packing sheet A before it is flipped.

[0194] The packing sheet A is configured such that a rearward-biased upper left offset portion is provided on the left side of the upper end; a forward-biased upper right offset portion is provided on the right side of the upper end; a rearward-biased lower left offset portion is provided on the left side of the lower end; and a forward-biased lower right offset portion is provided on the right side of the lower end. The adjacent packing sheet B is arranged in such a way that it is rotated 180° around the horizontal axis of the body of the packing sheet A.

[0195] Thus, the upper right offset portion of packing sheet A and the lower right offset portion of packing sheet B located on the front side of the stacking direction are joined together; the lower right offset portion of packing sheet A and the upper right offset portion of packing sheet B are joined together, thereby forming a first upper opening 210 between the upper left offset portion of packing sheet A and the lower left offset portion of packing sheet B, and forming a first lower opening 310 between the lower left offset portion of packing sheet A and the upper left offset portion of packing sheet B. The first upper opening 210 and the first lower opening 310 are respectively connected to the first heat exchange portion 401 formed between the body portion of packing sheet A and the body portion of packing sheet B in the vertical direction, thereby forming a first flow path R1.

[0196] The upper left offset portion of packing sheet A is joined to the lower left offset portion of packing sheet B located on the rear side in the stacking direction; the lower left offset portion of packing sheet A is joined to the upper left offset portion of packing sheet B, thereby forming a second upper opening 220 between the upper right offset portion of packing sheet A and the lower right offset portion of packing sheet B, and forming a second lower opening 320 between the lower right offset portion of packing sheet A and the upper right offset portion of packing sheet B. The second upper opening 220 and the second lower opening 320 are respectively connected to the second heat exchange portion 402 formed between the body portion of packing sheet A and the body portion of packing sheet B in the vertical direction, thereby forming a second flow path R2.

[0197] Furthermore, a left upper rectifier plate 230 is provided between the upper left offset portion of packing plate A and the lower left offset portion of packing plate B, extending from the first upper opening 310 to the first heat exchange portion 401, with its width gradually increasing and its thickness gradually decreasing.

[0198] Between the lower left offset portion of packing sheet A and the upper left offset portion of packing sheet B, a lower left rectifier plate 330 is provided, which extends from the first lower opening 310 to the first heat exchange portion 401, with its width gradually increasing and its thickness gradually decreasing.

[0199] Similarly, between the upper right bias portion of packing plate A and the lower right bias portion of packing plate B, a right upper rectifier plate 240 is provided, which extends from the second upper opening 220 to the second heat exchange portion 402, with its width gradually increasing and its thickness gradually decreasing.

[0200] Between the lower right offset portion of packing plate A and the upper right offset portion of packing plate B, a lower right rectifier plate 340 is provided, which extends from the second lower end opening 320 to the second heat exchange portion 402, with its width gradually increasing and its thickness gradually decreasing.

[0201] Based on this, if, as in the second embodiment, the left edge of each packing sheet A is offset forward to form a straight sealing portion 215A, the sealing portion of packing sheet A and the sealing portion 215B of packing sheet B located in the front of the stacking direction are joined together.

[0202] The sealing edge 215A of packing sheet A and the sealing edge 215B of packing sheet B located on the front side in the stacking direction are brought together and welded together to form the left sealing edge 215.

[0203] Therefore, according to this embodiment, the number of components can be further reduced. When assembling the packing module using packing sheets, it is only necessary to stack the unflipped packing sheet A and the 180° flipped packing sheet B in sequence.

[0204] Cooling Tower 1

[0205] Figure 10 This is a schematic diagram of a cooling tower manufactured based on the packing module 1 of this embodiment.

[0206] The bottom layer of the cooling tower 10 is an air intake layer 101, and multiple air dampers 102 are arranged around the air intake layer 101. Above the air intake layer 101, a packing layer 103 is arranged, which consists of multiple packing modules 1 arranged in a matrix on a horizontal plane. Above the packing layer 103, a spray section 104 is arranged, which sprays hot water to be treated onto each packing module 1 of the packing layer 103. In the area between the spray section 104 and the packing layer 103, a baffle 105 extending along the stacking direction of the packing modules 1 is generally vertically arranged, and multiple spacers 105a and 105b are enclosed by the baffle 105 and the top surface of the packing modules 1. Spacer 105a serves as the spraying space for hot water, and spacer 105b serves as the air intake space for drawing gas from bottom to top. Spray space 105a and air intake space 105b are alternately arranged in the direction perpendicular to the stacking direction of the matrix formed by the packing modules 1, and each partition 105 is arranged at the junction of the first upper opening 210 and the second upper opening 220 of the packing module 1, thereby separating the first flow path R1 and the second flow path R2 that are connected to the first upper opening 210 and the second upper opening 220.

[0207] Above the spray section 104 is the exhaust layer 106, and above the exhaust layer 106 is the exhaust port 108 equipped with a fan 107. The fan 107 draws air upward, causing cold air to enter the air intake layer 101 from the air damper 102 at the bottom of the cooling tower 10. The air then passes upward through the packing modules 1 of the packing layer 103, and passes through the spray space 105a and the air intake space 105b respectively. After further mixing in the exhaust layer 106, the air is discharged upward through the exhaust port 108.

[0208] On the other hand, the hot water to be treated, sprayed from the spray section 104 to each packing module 1 of the packing layer 103, is cooled by each packing module 1 and falls to the bottom of the air intake layer 101. The cooled water is then collected by the collection equipment for recycling in the factory.

[0209] Work Status 1:

[0210] As described above, the cooling tower 10 is set to winter operating mode. At this time, the hot water to be treated, sprayed from the spray section 104, is confined within the spray space 105a and enters one of the two flow paths of the packing module 1. In this embodiment, since the partition 105 is positioned relative to the packing module 1 at the junction of the first upper opening 210 and the second upper opening 220, the first and second flow paths R1 and R2 adjacent to each other between two adjacent packing modules 1 form water flow paths, while the outer flow paths R1 and R2 are adjacent to the second and first flow paths on both sides, respectively, forming air flow paths.

[0211] In the water flow path, the sprayed water flows into the packing module 1, and through the upper guide section 200, it forms a water film in the heat exchange section 400, which is distributed in a flat space covering approximately the full width of the packing module 1 and adheres to the two side walls of the flat space in the stacking direction. The adjacent flow paths on both sides in the stacking direction serve as air flow paths, and they exchange heat with the hot water in the water flow path through the walls of the packing sheets A and B.

[0212] When the cooling tower 10 operates in winter, the air drawn into the airflow path from below the packing module 1 is dry and cold air with low temperature and low moisture content. During heat exchange with the hot water in the airflow path through the packing module 1, because the heat exchange is completed entirely in independent flow paths separated by packing plates A and B, the air temperature rises when it exits from above the packing module 1, but the moisture content remains unchanged, thus forming hot dry air.

[0213] On the other hand, because hot water is sprayed down from the spray section 104 above in the water flow path, the air drawn in by the fan 107 in the water flow path experiences significant resistance, resulting in a very small airflow relative to the airflow through the air flow path, typically only a fraction of that. The air flowing through the air flow path will form hot saturated air, i.e., humid and hot air.

[0214] Dry, hot air flowing through the airflow path and humid, hot air flowing through the waterflow path mix in the exhaust layer 106. Because there is less humid, hot air is mixed with dry, hot air to form unsaturated hot air. After being discharged into the atmosphere through the fan 107 and the exhaust port 108, the unsaturated hot air is gradually cooled down, resulting in less moisture precipitation and greatly reducing the amount of fog formation.

[0215] In this embodiment, by switching the spray section 104, the spray space 105a and the air intake space 105b can be flexibly switched. That is, hot water is stopped from spraying the spray space 105a, while hot water is sprayed into the air intake space 105b. This allows the functions of the spray space 105a and the air intake space 105b to be switched. On the one hand, this ensures the normal operation of the cooling tower 10, and on the other hand, it allows for effective cleaning and maintenance of the flow path R1 or R2 of the packing module 1 connected to the air intake space 105b. Thus, the normal operation of the cooling tower 10 is not affected when cleaning and maintaining the cooling tower 10.

[0216] Work Status Two:

[0217] When operating in summer, the spray section 104 can be adjusted to spray hot water onto the air intake space 105b and the spray space 105a in the same way, which can ensure that the cooling tower 10 can maximize its heat exchange efficiency without fogging in summer.

[0218] Cooling Tower 20

[0219] In this embodiment, the packing module 1 described above is still used, but as a cooling tower 20, only the differences between it and the cooling tower 10 will be described in detail, and the same configuration will not be described again.

[0220] The cooling tower 20 of this embodiment differs from the cooling tower 10 described above in that, for each spray space 105a, a cover plate 109 is further provided horizontally above the partition 105 along the stacking direction of the packing module 1. Multiple space intervals 205a and 205b are formed by providing the cover plate 109, partition 105, and packing module 1. In this embodiment, the cover plate 109 is only provided in the spray space 205a for spraying hot water, while no cover plate 109 is provided in the exhaust space 205b for exhausting air. Alternatively, cover plates 109 can be provided in both the spray space 105a and the exhaust space 205b. The cover plate 109 can be a continuous plate or a combination of multiple plates, and can be flipped along one or both sides of the partition wall 105 to form a detachable or closable configuration, thereby enabling switching between the spray space 205a and the exhaust space 205b.

[0221] Work Status 1:

[0222] This working state is particularly suitable for winter in northern my country. Under this state, the working process of cooling tower 20 is similar to that of cooling tower 10. However, since a cover plate 109 is provided above the spray space 205a, the spray space 205a will not play the role of air intake in principle. Only hot water flows downward through the flow path R1 or R2 of the packing module corresponding to the spray space 205a. Therefore, in the exhaust layer 106 of cooling tower 20, there is only dry hot air from the air intake space 205b.

[0223] Therefore, only dry hot air is drawn out of the exhaust port 108 by the fan 107 in the cooling tower 20, so that the moisture in the hot air discharged by the cooling tower 20 is reduced as much as possible, thereby further improving the defogging ability of the cooling tower 20 in winter. Furthermore, since only dry hot air is discharged, the amount of water discharged by the cooling tower 20 is also less, which is more conducive to water conservation.

[0224] With both the spray space 205a and the air intake space 205b equipped with openable (hinged, split, or removable) covers 109, by opening the cover above the spray space 205a and closing the cover above the air intake space 205b, and adjusting the spray section 104, the functions of the spray space 205a and the air intake space 205b can be switched in the same way as the cooling tower 10. The flow path R1 or R2 of the packing module 1 corresponding to the original air intake space 205b is cleaned, thus preventing the cooling tower 20 from shutting down.

[0225] Of course, by only opening the cover plate 109, the same working state as the above-mentioned cooling tower 10 can be achieved, and its working efficiency and working results are also roughly the same.

[0226] Work Status Two:

[0227] In summer operation, by removing or opening the cover plate 109 above the spray space 205a, the spray section 104 is adjusted so that hot water is sprayed onto the air intake space 205b in the same way as the spray space 205a, so that the cooling tower 20 achieves the same summer operation state as the cooling tower 10, which improves heat exchange efficiency.

[0228] In the cooling tower 20 of this embodiment, the cover plate 109 provided above the partition spaces 205a and 205b is a flat plate, but it is not limited to this. It can also be a plate that extends from the partition plates 105 on both sides of the packing module 1 in the stacking direction of the partition spaces 205a and 205b towards the middle and overlaps to close the partition spaces 205a and 205b. An upward or downward apex is formed at the overlap. That is, as long as the upper part of the partition spaces 205a and 205b can be closed, there is no limitation on the configuration of the cover plate 109.

[0229] In the above embodiment, the rectifier 230 is disposed in the upper left guide portion 201 between the packing sheets BA in the stacking direction of the packing module 1, where the upper section of the first flow path R1 is formed in the upper left guide portion 201.

[0230] Furthermore, the rectifier 240 is disposed in the upper right guide portion 202 between the packing sheets AB in the stacking direction of the upper section guide portion 200 of the second flow path R2.

[0231] On the other hand, the rectifier 330 is disposed in the lower section guide portion 300 of the first flow path R1, which is formed in the lower left section guide portion 301 between the packing sheets BA in the stacking direction.

[0232] Furthermore, the rectifier 340 is disposed in the upper right guide portion 202 between the packing sheets AB in the stacking direction of the lower section guide portion 300 of the second flow path R2.

[0233] Since the first upper opening 210 and the second upper opening 220 each occupy approximately half the width of the packing module 1, the rectifier 230 is actually embedded in a roughly right-angled trapezoidal region formed by extending from approximately the middle of the upper edge of the packing piece BA, downward along the left edge of the upper guide section 200, then rightward along the lower end line of the side upper guide section 200 to the right edge of the upper guide section 200, and then diagonally upward towards approximately the middle of the upper edge of the packing piece A (B). For the packing piece A, it is offset to the rear in this right-angled trapezoidal region, while for the packing piece B, it is offset to the front. Thus, in the stacking direction, the front packing piece A and the rear packing piece B, i.e., the packing piece AB, are tightly joined around the periphery of the first upper opening 210. Therefore, the width of the opening in the stacking direction between the front packing piece B and the rear packing piece A, packing piece BA at the first upper opening 210 is 2d. In other words, within the right-angled trapezoidal region, the stacking distance at the first upper opening 210 at the top is approximately 2d, while the stacking distance at the lower end where it connects to the heat exchange section 400 is the interval d between the packing sheets A and B, thus forming the space of the upper left guide section 201.

[0234] The rectifier plate 230 has a folded cross-section in the horizontal direction that extends perpendicular to the stacking direction. The upper part near the first upper opening 210 has a large folding amplitude but a small folding span. As it extends from top to bottom towards the heat exchange section 400, the folding amplitude gradually decreases and the folding span gradually increases to fill the space of the upper left guide section 201. By forming a fold in the horizontal direction with the rectifier plate 230, multiple guide flow paths are formed from the first upper opening 210 to the heat exchange section 400. Each guide flow path is thicker at the upper end in the stacking direction and narrower in the horizontal direction, while it is thinner and wider at the lower end. This effectively and evenly guides the hot water flowing in from the first upper opening 210, which is approximately half the width of the packing module 1, to the heat exchange section 400, which is approximately the full width of the packing module 1. Furthermore, whether it is a single guide flow path or the entire guide flow path, the cross-sectional area change from top to bottom is minimized to reduce fluid resistance. Good throughput can be achieved for both hot water sprayed from above and air drawn in from below.

[0235] The same configuration is used for the rectifier 240 located in the space of the upper right guide section 202, except that its position is rotationally symmetrical with respect to the rectifier 240 in the horizontal direction.

[0236] For the rectifier plates 330 and 340, similar to the upper left guide plate 201 and upper right guide plate 202 located in the upper guide plate 200, they are respectively disposed in the lower left guide plate 301, which is formed by the area of ​​the inverted right-angled trapezoidal region of the packing plate BA at the lower guide plate 300 biased outward in the stacking direction, and the lower right guide plate 302, which is formed by the area of ​​the inverted right-angled trapezoidal region of the packing plate AB at the lower guide plate 300 biased outward in the stacking direction. The rectifier plates 330 and 340 form multiple flow paths in the lower left guide plate 301 and the lower right guide plate 302, respectively. These paths have a small thickness at the upper end in the stacking direction and a large width in the horizontal direction, while the lower end has a large thickness and a small width. This guides water from the heat exchange section 400, which has 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 have approximately half the width.

[0237] That is, for the rectifier plates 330 and 340, in an inverted manner, the bending amplitude is large and the bending span is small at the first and second lower openings 310 and 320. As they extend from bottom to top toward the heat exchange section 400, the bending amplitude gradually decreases and the bending span gradually increases.

[0238] Similarly, the rectifier 330 located in the space of the lower left guide section 301 and the rectifier 340 located in the space of the lower right guide section 302 are rotationally symmetrical in the horizontal direction.

[0239] Therefore, if the first and second upper openings 210 and 220 and the first and second lower openings 310 and 320 are approximately half the width of the packing module 1, and if the vertical lengths of the upper and lower guide sections 200 and 300 are the same, then the upper left guide section 201, the upper right guide section 202, the lower left guide section 301, and the lower right guide section 302 can form a rotationally symmetrical structure. Therefore, the rectifiers 230, 240, 330, and 340 can be identical components. This allows the packing module 1 to be manufactured using only three components: packing sheet A, packing sheet B, and a universal rectifier. This not only significantly reduces the mold cost and component production cost of the packing module 1, but also eliminates the need to consider the model differences of each rectifier when assembling the packing sheet A, packing sheet B, and rectifier, making assembly convenient and greatly reducing the overall production cost of the packing module 1.

[0240] According to the above preferred embodiment, by offsetting and attaching the packing sheet A and the packing sheet B to the upper guide section and the lower guide section respectively, the first upper opening, the second upper opening, the first lower opening and the second lower opening are stacked in the stacking direction. Without considering the thickness of the packing sheets A and B, the total size of the openings in the stacking direction is approximately the same as the stacking thickness of the packing module in the stacking direction.

[0241] [Fifth Implementation Method]

[0242] In this embodiment, the packing module 1000, like in the embodiments described above, also employs a configuration of multiple packing sheets arranged in alternating layers, and a first flow path and a second flow path are formed between the multiple packing sheets 1000A and 1000B, respectively. That is, as... Figure 17 As shown, in the stacking direction of the packing module from front to back, a first flow path 1000G is formed between packing sheets 1000A-1000B; and a second flow path 1000W is formed between packing sheets 1000B-1000A.

[0243] The difference from the above embodiments lies in the placement of the upper openings of the first flow path 1000G and the second flow path 1000W. In this embodiment, the upper opening G of the first flow path 1000G, which serves as the first upper opening, is located in the middle of the upper left-right direction of the filling module 1000; while the upper opening W of the second flow path 1000W, which serves as the second upper opening, includes an upper opening W1 located to the left of the upper opening G and an upper opening W2 located to the right of the upper opening G. That is, in this embodiment, the second flow path 1000W has two upper openings W, and is arranged such that it sandwiches the upper opening G of the first flow path 1000G.

[0244] In this embodiment, the upper opening G of the first flow path 1000G is connected to the first heat exchange section 401 of the first flow path 1000G via the upper guide section of the first flow path 1000G, thereby guiding the upper opening G located in the middle part in the upper width direction of the packing module 1000 to the first heat exchange section 401 that occupies approximately the full width of the packing module 1000.

[0245] The two upper openings W1 and W2 of the second flow path 1000W are connected to the second heat exchange section 402 of the second flow path 1000W via the upper guide section of the second flow path 1000W. The upper openings W1 and W2 located on both sides of the upper opening G of the first flow path 1000G in the upper width direction of the packing module 1000 are guided to the second heat exchange section 402, which occupies approximately the full width of the packing module 1000.

[0246] Specifically, in the front-to-back direction of the stacked packing sheets shown in the figure, a first flow path 1000G is formed between packing sheet 1000B and packing sheet A; a second flow path 1000W is formed between packing sheet 1000A and packing sheet 1000B. Between the heat exchange section 401 of the first flow path 1000G and the heat exchange section 402 of the second flow path 1000W, the distance between packing sheet 1000A and packing sheet 1000B is approximately uniform, that is, packing sheet 1000A and packing sheet 1000B are arranged approximately parallel to each other at portions of the first heat exchange section 401 and the second heat exchange section 402.

[0247] Furthermore, for packing sheet A and packing sheet B, an upper guide section 200 of the first and second flow paths 1000G and 1000W is provided on the heat exchange section 400 formed by the stacked first and second heat exchange sections 401 and 402.

[0248] In this embodiment, by offsetting the packing sheets 1000B and 1000A in opposite directions at the upper guide portion 200 from the upper opening G toward the first heat exchange portion 401, first offset portions 1100B and 1100A are formed, increasing the distance between them, thereby forming the first upper opening 1100 of the first upper guide portion 200G. Furthermore, due to the formation of the first offset portions 1100A and 1100B at the upper guide portion 200 of the packing sheets 1000A and 1000B, the packing sheets 1000A and 1000B are brought together at that portion.

[0249] On the other hand, by offsetting the packing pieces 1000A and 1000B in opposite directions at the upper guide portion 200 from the upper openings W1 and W2 on both sides of the upper opening G toward the second heat exchange portion 402, second offset portions 1200A and 1200B are formed, increasing the distance between them, thereby forming the second upper opening 1200 of the second upper guide portion 200W. Furthermore, due to the formation of the second offset portions 1200B and 1200A at the upper guide portion 200 of the packing pieces 1000B and 1000A, the packing pieces 1000B and 1000A are brought together at that portion.

[0250] In this embodiment, as described above, bias portions are formed on the upper sections of the packing sheets 1000A and 1000B, and a first upper opening 1100 and a second upper opening 1200 are formed on the upper section of the packing module 1000. Furthermore, a first upper opening G and second upper openings W1 and W2 are formed at the upper edges of the first upper opening 1100 and the second upper opening 1200. Consequently, in the first flow path 1000G, the first upper opening G, occupying a portion of the width of the middle part of the packing module 1000, connects to the first heat exchange section 401, occupying approximately the entire width of the packing module 1000; and in the second flow path 1000W, the second upper openings W1 and W2, occupying portions of the width of both sides of the packing module 1000, connect to the second heat exchange section 402, occupying approximately the entire width of the packing module 1000. Therefore, in one unit of the second flow path 1000W formed by packing sheets 1000A-1000B, the second upper openings W1 and W2 of the second flow path 1000W are connected to the common second heat exchange section 402.

[0251] Furthermore, the thickness of the first and second upper openings G, W1, and W2 in the stacking direction of the packing module 1000 is greater than the distance between their respective packing sheets 1000A and 1000B in the stacking direction at the heat exchange section 400.

[0252] In this embodiment, in order to make the fluid in the first flow path 1000G and the second flow path 1000W uniform, rectifiers are also provided in the first and second upper guide sections 200G and 200W, respectively.

[0253] As the first rectifier 1300G in the first flow path 1000G, it is disposed within the first upper guide section 200G between the first upper opening G and the first heat exchange section 401. The first upper guide section 200G serves to connect the first upper opening G to the first heat exchange section 401, which is approximately the full width. Therefore, the first rectifier 1300G disposed within the first upper guide section 200G is formed into an approximately isosceles trapezoid with multiple guide grooves whose width gradually increases from top to bottom.

[0254] Furthermore, the second rectifier 1300W, which is part of the second flow path 1000W, is disposed within the second upper guide section 200W between the second upper openings W1 and W2 and the second heat exchange section 402. The second upper guide section 200W serves to connect the second upper openings W1 and W2 to the second heat exchange section 402, which has approximately its full width. Therefore, the second rectifier 1300W disposed within the second upper guide section 200W is formed into approximately two right-angled trapezoids and has multiple guide grooves whose width gradually increases from top to bottom.

[0255] In this embodiment, as described above, since the front projection of the packing sheets 1000A and 1000B is approximately rectangular, the first upper opening 1100 of the first upper guide portion 200G formed by the first biasing portions 1100B and 1100A is formed as an inverted approximately triangular shape; and the second upper opening 1200 of the second upper guide portion 200W formed by the second biasing portions 1200A and 1200B is formed as an inverted approximately right-angled triangle located at the left and right corners of the upper ends of the packing sheets 1000A and 1000B. At this time, the first upper opening G and the second upper openings W1 and W2 are located at the upper edge of the packing module 1000.

[0256] Therefore, in the first rectifier 1300G and the second rectifier 1300W, at positions corresponding to the first upper opening 1100 and the second upper opening 1200 of the first and second upper section inlet portions 200G and 200W, inverted approximate triangles and inverted approximate right triangles are also formed longitudinal rectifier sections. The function of these longitudinal rectifier sections is to pre-separate the first and second upper section guide portions 200G and 200W of the first and second flow paths 1000G and 1000W, so as to ensure that the fluid flow rate in each guide groove is approximately uniform within the oblique rectifier section below it.

[0257] Furthermore, in this embodiment, in addition to forming a first upper opening 1100 and a second upper opening 1200 respectively by setting a bias portion in the first and second upper guide portions 200G and 200W, and setting a first and a second rectifier 1300G and 1300W, the first and second lower guide portions 400G and 400W can be formed by setting the same bias portion, and a third and a fourth rectifier 1300G' and 1300W' are set. This results in the formation of the same first and second lower openings.

[0258] Based on the packing module of this embodiment, when constructing a cooling tower, multiple packing modules can be arranged side by side in a generally horizontal direction. The differences from the first to fourth embodiments will be described in detail below.

[0259] (Usage Example 1)

[0260] In this embodiment, since the first upper opening G of the first flow path 1000G is located in the middle of the width direction of the packing module 1000, and the second upper opening W of the second flow path 1000W is located on both sides of the width direction of the packing module 1000, when the packing modules 1000 are arranged side by side, as... Figure 27 The diagram shown is a schematic representation of an example 1 of the use of the filler module 1000 in this embodiment.

[0261] Unlike the first to fourth embodiments, in this example, the lower end of the partition 2005 (i.e., the first partition) that separates the air flow path and the spray water flow path and is located above the packing module 1000, and the sealing portion between them and the packing module 1000, are all located inside the width direction of the packing module, and the situation described above, where the lower end of the partition 105 is located at the junction of the packing modules, is not present.

[0262] Specifically, the partition 2005 extends along the stacking direction, and the lower end of the partition 2005 corresponds to the connection between the first upper opening G and the second upper opening W in the width direction of the packing module 1000.

[0263] This makes it easier to seal between the packing module 1000 and the partition 2005, and separates the spray flow path and the air flow path as thoroughly as possible. As a result, the absolute humidity of the cold air flowing in from below the packing module 1000 remains unchanged after passing through the packing module 1000 and exchanging heat with the hot water in the adjacent flow path, and being discharged above the packing module 1000.

[0264] However, the air discharged above the packing module 1000 after heat exchange exchanges with the hot water in the adjacent flow path, thus becoming dry and hot air. While maintaining absolute humidity, the air temperature increases, and the relative humidity decreases significantly.

[0265] In this example, a partition 2005' (i.e., a second partition) is also provided below the packing module 1000. Specifically, the partition 2005' extends along the stacking direction, and its lower end corresponds to the connection point between the first lower opening and the second lower opening in the width direction of the packing module 1000. Therefore, within the cooling tower 2000, the sprayed hot water after passing through the packing module 1000 supplies as little moisture as possible to the cold air drawn in below the packing module 1000. Within the packing module 1000, the cold air is isolated from the hot water in the adjacent flow path and does not supply moisture to the air flow path. Consequently, when the drawn-in cold air is discharged above the packing module 1000, the partition 2005 further prevents moisture from being obtained from the spray section.

[0266] Therefore, in this application example, by isolating the airflow path from the spray water within the cooling tower 2000 as much as possible, the amount of moisture supplied to the intake air can be minimized. On the other hand, in the spray water flow path, because a closed valve plate 2009 is installed above the nozzle, the hot air from the spray water mixes into the exhaust air as little as possible, and is also separated from the intake cold air below the packing module 1000 by a baffle plate 2005'. Thus, the spray water forms a closed flow path, minimizing the supply of moisture to the intake and exhaust air of the cooling tower 2000. As a result, even in the winter of northern my country, the amount of mist discharged from the cooling tower 2000 can be greatly reduced.

[0267] (Usage Example 2)

[0268] Alternatively, valve plate 2009 can be set to an inactive state (open or not set), becoming as follows: Figure 28 Even so, as shown, the cold air drawn in below the packing module 1000, after being discharged above the packing module, only has a small amount of water vapor mixed with the heat-exchanged cold air above the partition 2005.

[0269] Because the temperature of the cooled air increases after heat exchange while the absolute humidity remains unchanged, the saturation is low. On the other hand, the amount of water from the spray path is limited. Therefore, the air with significantly reduced saturation after heat exchange can be effectively utilized to absorb the water released from the spray section. Except in cases where the temperature is very low in winter, the cooling tower 2100 of this application example 2 can also effectively achieve the defogging effect.

[0270] In the above-described usage examples 1 and 2, the first flow path 1000G is used as the air flow path, and the second flow path 1000W is used as the hot water spray flow path. Therefore, the portion between adjacent packing modules 1000 is confined to the range of the hot water spray flow path. In this case, the first flow path 1000G, as the air flow path, ensures the airtightness between the lower end of the baffle 2005 and the packing module 1000, allowing as much air as possible drawn into the cooling tower 2000 to flow through the first flow path 1000G.

[0271] Regarding the installation of packing modules, gaps are inevitable between them; otherwise, installation would be problematic. In this embodiment, the packing module 1000 has a first upper opening G located in the middle of its width direction, and second upper openings W located on either side of its width direction. This ensures that adjacent upper openings of adjacent packing modules 1000 are both second upper openings W, which can then be used as inlets for hot water spraying. This effectively reduces air leakage from the installation gaps between the packing modules 1000. In embodiments one through four, gaps between packing modules 1000 inevitably exist in the airflow path, causing some air to bypass the packing modules and flow directly through these gaps, potentially reducing heat exchange efficiency. Furthermore, if the gaps between the packing modules 100 are too large due to construction errors or mistakes, the airflow through the gaps between the packing modules 100 will increase significantly, making it even more difficult to ensure uniform air resistance of the entire cooling tower. This will inevitably affect the stacking direction of each packing module in the entire cooling tower and the uniformity of heat exchange efficiency between the packing modules.

[0272] Using the filler module 1000 of this embodiment will properly solve the above problems.

[0273] (Usage Example 3)

[0274] As an example of the use of the packing module 1000 in this embodiment, in addition to having the advantages of the above-described examples 1 and 2, it can further improve the heat exchange efficiency of the cooling tower, significantly reduce the cost of the packing module, and further enhance the ease of installation and maintenance. A detailed description follows.

[0275] In this use case, such as Figure 29 As shown, a cooling tower 3000 is constructed using a packing module 1000. Below, only the differences between the cooling tower 3000 and the aforementioned embodiment will be explained.

[0276] In the cooling tower 3000, unlike the aforementioned, each packing module 1000 is provided with a predetermined installation interval 3999 of 300-600mm, and preferably a sealing plate 3998 is provided on the mounting surface at the interval between the packing modules 1000. If the sealing plate 3998 is not provided, the support frame that serves as the mounting base for the packing module 1000 can be made to have a plane corresponding to the interval between the packing modules 1000.

[0277] In this case, in contrast to the aforementioned usage examples 1 and 2, it is preferable to use the second flow path 1000W of the packing module 1000 as the air flow path and the first flow path 1000G as the spray water flow path.

[0278] In this way, when designing the cooling tower 3000, the packing modules 1000 can be spaced out, and the installation interval 3999 allows personnel to enter during the installation and maintenance of the packing modules 1000, thereby moving and inspecting the status of the packing modules 1000 relative to each other.

[0279] In particular, during the installation of the packing modules 1000, due to the relatively long distance between them in the stacking direction, the packing modules 1000 are typically divided and stacked only to a specified thickness to form units. These units are then arranged in a straight line and close to each other in the stacking direction to form a complete row of packing modules 1000. Therefore, during the installation of the cooling tower 3000, to ensure minimal air and water leakage, it is essential to ensure that all units of the packing modules 1000 are installed in a straight line. However, when there is no installation interval 3999 between the packing modules 1000 in the lateral direction, adjusting the straightness of the units in the longitudinal direction is almost impossible. Precise control of installation accuracy is necessary when installing each unit, thus installation efficiency needs to be improved.

[0280] In this application example, since an installation interval 3999 is provided between the packing modules 1000 in the lateral direction, the operator can easily adjust the units of each packing module 1000 by means of the installation interval 3999 when installing the modules of each packing module 1000 in the stacking direction. Even if a unit is damaged due to some special accident, the damaged unit can be disassembled, and the units in front of and behind it can be easily moved to fill the gap, and a new unit can be added from the stacking end of the packing module 1000 to complete the repair.

[0281] When a sealing plate 3998 is installed in installation interval 3999, it is preferable that the sealing plate 3998 can be removed or erected, thus rendering the sealing plate 3998 ineffective. At this time, since the second flow path 1000W is set as an air flow path, a large amount of air passes through only installation interval 3999. This significantly reduces the cooling efficiency for hot water, which can meet some special needs in factory production.

[0282] (Usage Example 4)

[0283] Figure 30 This is a schematic diagram of usage example 4. In this usage example, similar to usage example 3, a gap is provided between the packing modules 1000 in the lateral direction, but a common packing module F is further filled in the gap.

[0284] As a standard packing module F, it can be any existing packing module. For example, it can be the most widely used packing module F that simply uses multiple packing sheets stacked together, in which case there are no separated flow paths in the packing module F. For the thin-plate heat exchange space formed by adjacent packing sheets in each of the two stacking directions, hot water is poured in from the top opening, and the fan of the cooling tower 4000 is used to draw cold air into the packing module F from the bottom opening, so that the air and hot water come into direct contact for heat exchange.

[0285] As shown above, in this example, it is preferable to use the second flow path 1000W as the flow path for hot water spraying, and the first flow path 1000G as the air flow path. Thus, in this example, hot water is supplied to both the second flow path 1000W and the packing module F. The hot water flowing into the packing module 1000 through the second upper openings W1 and W2 exchanges heat with the air drawn in from the second lower opening G' of the packing module 1000 within the packing module 1000. On the other hand, the hot water sprayed into the packing module F directly contacts the air drawn in from its lower end within the packing module F, and exchanges heat with it.

[0286] Therefore, the air discharged upward from the first upper opening G of the packing module 1000 forms hot air with low saturation, while the hot air flowing out from the upper end of the packing module F becomes saturated hot air.

[0287] On the other hand, due to the setting of the second upper openings W1 and W2, the air resistance in the second flow path 1000W is very large. Therefore, the amount of air discharged upward from the second upper opening W of the packing module 1000 is actually very small, which is much smaller than the amount of air passing through the packing module F.

[0288] Therefore, the low-saturation hot air discharged from the first upper opening G of the packing module 1000, the saturated hot air discharged from the packing module F, and a very small amount of saturated hot air discharged from the second upper opening W1 / W2 of the packing module 1000 are mixed above the packing module. This effectively utilizes unsaturated hot air, reduces the saturation of the mixed air, and greatly improves the heat exchange efficiency of the cooling tower while ensuring sufficient defogging effect.

[0289] According to the packing module 1000 of this embodiment, by providing a first upper opening G in the middle of the width direction at the top, and providing second upper openings W (W1, W2) on both sides of the first upper opening G, the packing module 1000 allows for greater flexibility when constructing cooling towers 2000, 2100, 3000, 4000, etc., and also allows for flexible configuration of air and hot water channels. Especially when using the first flow path 1000G connected by the first upper opening G as the air flow path, the isolation between the air flow path and the hot water spray flow path is more thorough. This minimizes the relative humidity of the air after heat exchange, improving the defogging effect, which is particularly suitable for the winter conditions in northern my country.

[0290] However, the packing module 1000 and the cooling tower having the packing module 1000 provided in this embodiment are not limited to the situation described in this embodiment.

[0291] In this embodiment, the packing module 1000 includes upper section guide portions 200G and 200W located in the upper section and heat exchange portions 401 and 402 below them. Alternatingly stacked first flow path 1000G and second flow path 1000W are formed by alternately overlapping packing sheets 1000A and 1000B. The first flow path 1000G includes a first heat exchange portion 401, and the second flow path 1000W includes a second heat exchange portion 402. The first heat exchange portion 401 and the second heat exchange portion 402 overlap to form a heat exchange portion 400.

[0292] The packing sheet 1000A has a biasing portion 1100A in the middle of the upper guide section, which is biased forward in the stacking direction, and biasing portions 1100B on both sides of the upper guide section, which are biased rearward in the stacking direction. The packing sheet 1000B has a biasing portion 1200A in the middle of the upper guide section, which is biased rearward in the stacking direction, and biasing portions 1200B on both sides of the upper guide section, which are biased forward in the stacking direction.

[0293] Thus, by stacking packing sheet 1000A and packing sheet 1000B, a first upper opening G is formed by the offset portions 1100A and 1100B of packing sheet 1000A and packing sheet 1000B formed in the middle of the upper guide portion. A second upper opening W is formed by the offset portions 1200A and 1200B of packing sheet 1000B and packing sheet 1000A formed on both sides of the upper guide portion.

[0294] In the first flow path 1000G, the first upper opening G is connected to the first heat exchange section 401 of the packing module 1000, which is approximately the full width of the packing module. In the second flow path 1000W, the second upper opening W is connected to the second heat exchange section 402 of the packing module, which is approximately the full width of the packing module.

[0295] In this embodiment, a lower guide section is further provided below the heat exchange section. For the first and second flow paths 1000G and 1000W, the configuration of the lower guide section is the inversion of that of the first and second upper guide sections 200G and 200W. That is, it includes a corresponding biasing section and an inclined flow guide section that forms the first and second lower end openings and is embedded in the guide section including the biasing section to obliquely connect the first and second lower end openings with the first and second heat exchange sections 401 and 402, thus forming a rectifier plate 1300G' and 1300W'. At this time, the same parts as the rectifier plates 1300G' and 1300W' can be used as rectifier plates 1300G' and 1300W, and they can be inverted.

[0296] The rectifier plates 1300G and 1300W are located in the upper guide section of the packing module 1000. Especially when guiding hot water inflow, it is necessary to guide the spray hot water from the first upper opening G or the second upper opening W (W1, W2) in the middle of the width direction to the first heat exchange section 401 or the second heat exchange section 402, which is approximately the full width. Therefore, the lower end of the rectifier plate bends to form the guide channel and gradually flattens to make the guided fluid evenly distributed on the heat exchange section surface of the packing plates 1000A and 1000B. However, for the rectifier plates 1300G” and 1300W”, since they are in the lower guide section, uniformity does not need to be considered when guiding the spray water out of the packing module 1000. Therefore, the flattened part can be removed, and only the guide flow path part formed by the bend is retained. This also avoids the accumulation of impurities in the water and blockages after long-term use when low-flow-rate fluids, especially hot water from spray, flow out of the packing module 1000 due to the flattened portion at the top of the rectifier plates 1300G' and 1300W' narrowing the flow path.

[0297]

Packaging Assembly 5100

[0298] As mentioned earlier, when installing the packing module 1000, it is typically stacked in sections to a specified thickness (e.g., 1-3 meters). The units forming the packing module 1000 are arranged in a straight line close to each other along the stacking direction, creating a complete row of packing modules 1000. Therefore, during the installation of the cooling tower 3000, to minimize air and water leakage, it is essential to ensure that all units of the packing module 1000 are installed in a straight line. However, when installing the packing modules 1000 on-site, since the work is done inside the cooling tower, manual placement of each packing module 1000 is often required, which is difficult. Furthermore, unavoidable factors such as tolerances and deformation of the packing modules 1000 mean that the connection surfaces between adjacent packing modules 1000 in the stacking direction cannot be tightly fitted together, easily leading to leaks. In cold winters, water that leaks into the airflow path can form ice crystals, causing blockages and even damage to the equipment.

[0299] To solve the above problems, such as Figure 31 and Figure 32 As shown, this embodiment provides a packing assembly 5100, which includes a packing module 1000 and a packing frame 5110 surrounding the outside of the packing module. The length of the packing assembly 5100 in the packing sheet stacking direction is greater than the width of the packing assembly 5100. In actual engineering, the packing module 1000 can be manufactured in a factory, and the aforementioned packing frame 5100 can be installed on its outside.

[0300] For example, the length of the packing assembly 5100 in the packing sheet stacking direction is approximately equal to half the length in the corresponding direction within the cooling tower's internal space. Thus, as... Figure 33 and Figure 34 As shown, packing assembly 5100 and packing assembly 5100' each occupy half the length of the cooling tower in the corresponding direction. Figure 34 The packing assembly 5100 is installed into the cooling tower from the left side using hoisting equipment or tools. Figure 34 On the right side, hoisting equipment or tools are used to install the packing assembly 5100' into the cooling tower. Using this method, each packing assembly 5100 and 5100' can be quickly installed into the cooling tower during construction, significantly improving the speed of packing layer installation and reducing the probability of leakage at the connection surfaces between packing modules.

[0301] In some embodiments, the packing frame 5100 can be formed by welding, screw connection, or other methods using profiles such as square tubes and angle iron. The components forming the packing frame 5100 can be located at various corners of the packing module 1000. To improve the strength of the packing frame 5100, at least one horizontal, vertical, or inclined tie rod 5111 can also be provided.

[0302] like Figure 31 and Figure 32 As shown, 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 pipes 5210 of the spray system can be fixed to the top of the upper frame 5120, and the nozzles 5220 can be installed in appropriate positions.

[0303] In addition, the aforementioned upper frame 5120 can have a split structure, that is, multiple upper frame 5120 splits are assembled to form an upper frame 5120, and the upper frame 5120 is installed on the upper side of the packing frame 5110, which reduces the weight of a single split and facilitates transportation and assembly.

[0304] like Figure 33 As shown, by setting the above-mentioned packing frame 5110 and upper frame 5120, support can be provided for the installation of partition 2005 and partition 2005', without having to build a crossbeam in the cooling tower, which improves the convenience of installation and the sealing performance of partition 2005 and partition 2005'.

[0305]

Packaging Assembly 6100

[0306] In the above implementation, the entire packing assembly needs to be assembled in the factory and then transported to the construction site for installation in the cooling tower by hoisting as a whole. This results in the packing assembly 5100 being large in size, making construction, transportation and installation inconvenient.

[0307] However, if the above frame 5110 is simply divided into segments, other problems will arise: it is not easy to form an effective seal between the packing segments, the flow path between two adjacent packing segments is blocked or blocked, and cannot be effectively utilized; the integral frame also has an adverse effect on the assembly of the packing sheets.

[0308] Figure 35 This is a schematic diagram of the external structure of the packing module. Regarding the above technical issues, the following section, in conjunction with the attached diagram, provides further details. Figure 35 Explanation will be provided. (Attached) Figure 35The diagram shows two packing modules 1000a and 1000b. The upper sections of both packing modules 1000a and 1000b form a first upper opening 1100 and a second upper opening 1200. Furthermore, a first upper opening G and second upper openings W1 and W2 located on either side of the width of the first upper opening G are formed at the upper edges of the first upper opening 1100 and the second upper opening 1200. A first upper partition region E1 is formed between the first upper opening G and the second upper opening W1, and a second upper partition region E2 is formed between the first upper opening G and the second upper opening W2. Due to the deflection of the packing sheet, the first upper partition region E1 and the second upper partition region E2 often have a tortuous structure, which poses a certain difficulty for effective separation between the first upper opening G and the second upper openings W1 and W2.

[0309] In addition, a first lower opening G' corresponding to the first upper opening G can also be formed on the lower end face of the filling modules 1000a and 1000b; a second lower opening W1' and W2' corresponding to the second upper openings W1 and W2; a first lower partition area E1' is formed between the first lower opening G' and the second upper opening W1'; and a second lower partition area E2' is formed between the first lower opening G' and the second lower opening W2'.

[0310] Figure 35 Two packing modules 1000a and 1000b in a stacked direction are also shown. When they are joined together, it is difficult to form an effective seal at the connection end faces. If sealing material is filled between the close end faces of the two packing modules 1000a and 1000b, but the packing sheet is a thin plastic sheet, its strength is insufficient to apply sufficient compressive force to the sealing material, often causing seal failure. Furthermore, the above-mentioned sealing method also causes the flow path at the connection of packing modules 1000a and 1000b to be blocked, resulting in failure.

[0311] To address the aforementioned technical problems, the present invention proposes a packing assembly 6100 that is easy to assemble, seal, transport, and install, and can effectively utilize the flow path at the connection between two adjacent packing assemblies 6100 in the packing sheet stacking direction, thereby increasing the heat exchange area.

[0312] Figure 36 This is a front view of a packing assembly 6100 formed by installing the packing module of the fifth embodiment of this utility model in a packing frame of another structure. Figure 37 yes Figure 36 A magnified view of a portion of the image;

[0313] like Figure 36 and 37As shown, the packing assembly 6100 includes a lower bracket 6110 and an upper bracket 6120, as well as a tensioning assembly 6130 that tensions and connects the lower bracket 6110, the packing module 1000 and the upper bracket 6120.

[0314] Multiple filler sheets are assembled using methods such as bonding and ultrasonic welding. Figure 35 The packing module is shown. The packing module 1000 is placed on the lower bracket 6110, and the upper bracket 6120 is placed on top of the packing module 1000. Sealing strips 6142 are provided between the upper bracket 6120 and the first and second upper partition areas E1 and E2, and between the lower bracket 6110 and the first and second lower partition areas E1' and E2'. The length and width of the sealing strips 6142 are suitable for covering the corresponding partition areas.

[0315] The upper end of the tensioning assembly 6130 is connected to the upper bracket 6120, and the lower end is connected to the lower bracket 6110. This tensions the upper bracket 6120 and the lower bracket 6110 towards the packing module 1000 in the vertical direction, compressing the sealing strip 6142 to induce a certain amount of deformation. This creates an effective separation seal between the first upper opening and the second upper opening, and between the first lower opening and the second lower opening. The tensioning assembly 6130 can be, for example, a combination of a slender double-ended bolt and nut, or it can be implemented using a wire rope.

[0316] like Figure 37 As shown, the upper bracket 6120 includes a first upper support portion 6121 and a second upper support portion 6122. The first upper support portion 6121 corresponds to the first upper partition area E1, and the second upper support portion 6122 corresponds to the second upper partition area E2. The extending direction of the first upper support portion 6121 and the second upper support portion 6122 is the same as the stacking direction of the packing sheets. The length of the first upper support portion 6121 and the second upper support portion 6122 is approximately the same as the thickness of the packing module 1000 in the stacking direction.

[0317] The lower bracket 6110 includes a first lower support portion 6111 and a second lower support portion 6112. The first lower support portion 6111 corresponds to the first lower partition area E1', and the second lower support portion 6112 corresponds to the second lower partition area E2'. The extending direction of the first lower support portion 6111 and the second lower support portion 6112 is the same as the stacking direction of the packing sheets. The length of the first lower support portion 6111 and the second lower support portion 6112 is approximately the same as the thickness of the packing module 1000 in the stacking direction.

[0318] Figure 38 This is a schematic diagram of the packing assembly of this embodiment;

[0319] like Figure 38As shown, the upper bracket 6120 also includes multiple upper crossbeams 6123, which are fixedly connected to the first upper support 6121 and the second upper support 6122, respectively. The upper crossbeams 6123 extend along the width direction of the packing module 1000. The number of upper crossbeams 6123 can be set according to the stacking thickness of the packing module, so as to apply a uniform force to the sealing strip 6142 and avoid leakage caused by uneven force on the sealing strip.

[0320] Correspondingly, the lower bracket 6110 includes multiple lower crossbeams 6113, which are fixedly connected to the first lower support 6111 and the second lower support 6112 respectively, and the lower crossbeams 6113 extend along the width direction of the packing module 1000.

[0321] The lower crossbeam 6113 corresponds to the upper crossbeam 6123. The upper end of the aforementioned tensioning assembly 6130 is connected to the end of the upper crossbeam 6123, and the lower end is connected to the end of the lower crossbeam 6113.

[0322] In this embodiment, the packing assembly 6100 achieves modularity of the packing module 1000 through the lower bracket 6110 and the upper bracket 6120. It is only necessary to stack the upper bracket 6120, the packing module 1000 and the lower bracket 6110 on top of each other, which improves the installation efficiency. Furthermore, the tensioning assembly 6130 can transmit the compressive force to the sealing strip 6142 through the lower bracket 6110 and the upper bracket 6120, causing the sealing strip 6142 to deform and thus separate the openings on the left and right sides of the partition area.

[0323] The packing assembly 6100 of this embodiment further includes a water-blocking groove 6150 connecting the partition 2005 and the upper bracket 6120. The water-blocking groove 6150 is connected to the upper bracket 6120 and includes a first sidewall 6151 and a second sidewall 6152. A receiving groove 6153 with an upward opening is formed between the first sidewall 6151 and the second sidewall 6152 to receive the lower edge of the partition 2005. Preferably, the first sidewall 6151 is located near the spray space 205a, and the height of the first sidewall 6151 is lower than the height of the second sidewall 6152, so that water falling from the spray space 205a into the receiving groove 6153 can overflow from the side where the first sidewall 6151 is located, instead of flowing into the air-drawing space 205b, thus preventing freezing.

[0324] In this embodiment, the water-blocking groove 6150 extends in the same direction as the first upper support 6121 and the second upper support 6122, and is fixedly connected.

[0325] Figure 39 This is a schematic diagram of the assembly structure of multiple packing assemblies 6100, showing the top structure of the packing assembly 6100;

[0326] Figure 40 This is a schematic diagram of the connection structure of two packing assemblies 6100a and 6100b that are adjacent in the stacking direction; Figure 41 This is a schematic diagram of the assembly structure of multiple packing assemblies 6100, showing the bottom structure of the packing assembly.

[0327] like Figures 38-41 As shown, it is assembled in the production workshop as follows Figure 38 The packing assembly 6100 shown is a single unit; when installed in a cooling tower, multiple packing assemblies 6100a, 6100b, 6100c, and 6100d are connected sequentially in the stacking direction, which improves the convenience of transportation and installation.

[0328] like Figure 40 As shown, packing assemblies 6100a and 6100b are aligned in the stacking direction. The first upper support portion 6121a of packing assembly 6100a and the first upper support portion 6121b of packing assembly 6100b extend in the same direction, and a sealing gasket 6160 is placed and pressed between their end faces, thereby providing a sealing effect at the connection (corresponding to the first upper partition area E1). Preferably, a bolt assembly can be provided at the connection end face to connect and press the sealing gasket 6160.

[0329] Similarly, the second upper support portion 6122a of the packing assembly 6100a extends in the same direction as the second upper support portion 6122b of the packing assembly 6100b, and a sealing gasket 6160 is placed and pressed between their end faces to achieve a sealing effect at the connection (corresponding to the second upper partition area E2).

[0330] For the connection between packing assembly 6100a and packing assembly 6100b, a horizontal tie rod 6150 as shown in the figure can be used. One end of the horizontal tie rod 6150 is connected to packing assembly 6100a, and the other end is connected to packing assembly 6100b, thus achieving a reliable connection between the two. The location of the horizontal tie rod 6150 can be selected in several ways. For example, it can be installed by tightening the upper crossbeam 6123a of packing assembly 6100a and the upper crossbeam 6123b of packing assembly 6100b. In this case, for ease of installation, the upper crossbeam 6123a can be located at the end of packing assembly 6100a near the stacking direction.

[0331] In this embodiment, the flow path at the connection of the stacked packing assemblies 6100a and 6100b is not blocked, and the first upper partition area E1 and the second upper partition area E2 at the connection are effectively sealed. With the help of adhesive and other means, the flow path at the connection can be ensured to work effectively, thereby improving the overall heat exchange area of ​​the cooling tower.

[0332] like Figure 41As shown, the first lower support portion 6111a and the second lower support portion 6112a of the packing assembly 6100a and the first lower support portion 6111a and the second lower support portion 6112b of the packing assembly 6100b can also be connected in the manner described above, and a sealing gasket 6160 is provided at the connection to achieve sealing at the corresponding position, which will not be described in detail here.

[0333] Alternatively, the packing module 1000 in this embodiment can also be a packing module 1. The upper end of the packing module 1 has a first upper opening 210 and a second upper opening 220, with an upper partition area between the first upper opening 210 and the second upper opening 220. The lower end of the packing module 1 has a first lower opening 310 and a second lower opening 320, with a lower partition area between the first lower opening 310 and the second lower opening 320. When constructing the packing assembly, it is necessary to adjust the number and position of the upper support portion and the upper partition area in the upper bracket accordingly, and to adjust the number and position of the lower support portion and the lower partition area in the lower bracket accordingly. The protection scope of this utility model covers the above-mentioned technical solutions.

[0334] Cooling Tower 7000

[0335] In cooling towers with dual-flow-path packing modules, ice formation is prone to occur in certain areas inside the cooling tower, especially near the tower wall, during cold winter weather. To address this technical problem, this embodiment provides a cooling tower 7000, which is described in detail below.

[0336] Figure 42 This is a top view of a cooling tower consisting of packing components.

[0337] like Figure 42 As shown, in the left-right direction of the coordinate system, the cooling tower 7000 has spray spaces 205a and air intake spaces 205b arranged horizontally and alternately. The spray section 7300 includes a water supply pipe 7310, a first spray manifold 7320, and a second spray manifold 7330. The first spray manifold 7320 is located in the spray space 205a, and the second spray manifold 7330 is located in the air intake space 205b. In the non-fogging mode, both the first spray manifold 7320 in the spray space 205a and the second spray manifold 7330 in the air intake space 205b spray hot water to maximize heat exchange efficiency; in the fogging mode, only the first spray manifold 7320 in the spray space 205a sprays hot water, and only air circulates in the air intake space 205b.

[0338] Inside the cooling tower, a first end isolation zone 7210 and a second end isolation zone 7220 are respectively provided at both ends in the front-to-back direction (i.e., the direction of packing plate stacking). For example... Figure 42As shown, the internal dimension of the cooling tower 7000 in the front-to-back direction is M, and the length of the spray space 205a is f, where f < M, which provides space for the first and second end isolation zones 7210 and 7220. A first end branch pipe 7340 extending in the left-right direction is provided within the first end isolation zone 7210. This first end branch pipe 7340 is connected to the second spray manifold 7330 and only operates in the non-fogging mode. A second end branch pipe 7350 extending in the left-right direction is provided within the second end isolation zone 7220. This second end branch pipe 7350 is connected to the second spray manifold 7330 and also only operates in the non-fogging mode. By setting the first end isolation zone 7210 and the second end isolation zone 7220, a buffer zone is established between the tower wall of the cooling tower 7000 and the spray space 205a. Even if water droplets leak or splash out from the spray space 205a, they will fall into the first and second end isolation zones 7210 and 7220 and will not form wall flow and freeze on the inner surface of the cooling tower wall.

[0339] Figure 43 yes Figure 42 The elevation section view of the cooling tower shown; Figure 44 This is a partial three-dimensional structural diagram of a cooling tower consisting of packing components and baffles.

[0340] like Figure 43 and Figure 44 As shown, to form the first and second end isolation zones 7210 and 7220, end partitions 2006 are provided at both ends of the partition 2005 in the front-rear direction. The end partitions 2006 can extend, for example, in the left-right direction. The partition 2005 and the end partitions 2006 confine the spray space 205a within the space formed by the two, while the air intake space 205b is formed on the outside of the partition 2005 and the end partitions 2006.

[0341] An omnidirectional ordinary packing module F can be installed in the first end isolation region 7210 and the second end isolation region 7220, which can meet the heat exchange requirements in non-fogging mode and has low manufacturing cost. Furthermore, as... Figure 43 As shown, packing modules F can also be installed between packing assemblies 6100 (in the left and right directions).

[0342] The difference between this embodiment and the above-described usage example 4 is that, in this embodiment, in the defogging mode, the flow path between the first upper opening and the first lower opening of the packing module 1000 is used as the flow path for water spraying; while the flow path between the second upper opening and the second lower opening, as well as the flow path formed within the packing module F, are used as the flow path for air passage.

[0343] Alternatively, the packing module 1 of the first embodiment of this utility model can be used instead of the packing module 1000. The packing module 1 includes packing sheets A and B stacked alternately at a predetermined interval d, forming an alternating first flow path R1 and a second flow path R2 within the packing module 1. An upper guide portion 200 and a lower guide portion 300 are formed in the upper and lower sections of the packing module 1, respectively, and a heat exchange portion 400 is formed in the middle section. For details, please refer to Embodiment 1 of this utility model, which will not be repeated here. Similarly, a first end isolation area and a second end isolation area can be provided at the end of the packing module 1 in the stacking direction before the inner surface of the cooling tower to prevent icing; and further, the packing module F can be filled to increase the heat exchange area of ​​the cooling tower in summer while preventing icing.

[0344] The preferred embodiment of the present invention, the packing module, and the cooling tower having the packing module have been described in detail above. However, those skilled in the art can make various modifications, alterations, and combinations based on this description, and all such modifications, alterations, and combinations fall within the protection scope of the claims of this application.
