[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. Its principle is to use the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature and ensure the normal operation of the system.

[0066] Other objects and advantages of the present invention will become apparent through explanation of the following preferred embodiments of the present application.

[0067] Below, in conjunction with the accompanying drawings, the preferred embodiments of the present utility model are described in detail.

[0068]

Packing module 1

[0069] In this embodiment, the packing module 1 includes packing sheets A and packing sheets B alternately stacked at a predetermined interval d. The stacked packing sheets A and B form alternately stacked first flow paths R1 and second flow paths R2 in the packing module 1 .

[0070] An upper guide portion 200 and a lower guide portion 300 are formed at the upper and lower sections of the filler module 1 , respectively, and a heat exchange portion 400 is formed at the middle section.

[0071] [Upper guide section 200]

[0072] At the upper end of the upper guide portion 200, a guide port is formed by alternating upper end portions of rectangular filler pieces A and B, as described below.

[0073] On one side (left side in the figure) perpendicular to the stacking direction, the upper end of the packing sheet A is offset to one side (back side in the figure) of the stacking direction, while the upper end of the packing sheet B is offset to the opposite side (front side in the figure), so that the upper ends of the left sides of the packing sheet A and the packing sheet B are attached to each other in the stacking direction from the front side to the back side in the figure, and the upper ends of the left sides of the packing sheet B and the packing sheet A are open to each other to form a first upper end opening 210. For the packing module 1, a plurality of first upper end openings 210 are arranged in parallel in the stacking direction. Thus, the first upper end opening 210 is connected to the first flow path R1 formed between the packing sheet B and the packing sheet A.

[0074] The upper end of the packing sheet A on the other side (right side in the figure) perpendicular to the stacking direction is offset to the other side (front side in the figure) of the stacking direction, while the upper end of the packing sheet B is offset to the opposite side (rear side in the figure), so that the upper ends of the right sides of the packing sheet B and the packing sheet A are attached to each other in the stacking direction from the front side to the rear side in the figure, and the upper ends of the right sides of the packing sheet A and the packing sheet B are open to each other to form a second upper end opening 220. For the packing module 1, a plurality of second upper end openings 220 are arranged in parallel in the stacking direction. Thus, the first upper end opening 220 is connected to the first flow path R2 formed between the packing sheet A and the packing sheet B.

[0075] In the upper guide portion 200, a left upper path rectifying piece 230 is embedded in the first flow path R1 between the heat exchange portion 400 surrounded by the packing sheet B-packing sheet A and the first upper end opening 210 formed by the packing sheet B-packing sheet A. The upper end of the left upper path rectifying piece 230 matches the width of the first upper end opening 210, and the width gradually increases from top to bottom, and the lower end corresponds to the width of the heat exchange portion 400 (the first heat exchange portion 401 of the first flow path).

[0076] In this embodiment, the left upper path rectifying piece 230 has a flexural shape in the transverse cross section perpendicular to the stacking direction, and the two sides of the flexural stacking direction, namely, the back side abuts against the front surface of the packing piece A clamping it, and the front side abuts against the rear surface of the packing piece B clamping it. Thus, in the first flow path R1 formed between the first upper end opening 210 and the heat exchange part 400, which is approximately a right-angled trapezoid, a guide portion is formed that guides from the width of the first upper end opening 210 to the full width of the heat exchange part 400 that is approximately the width of the packing pieces A and B.

[0077] In the upper guide portion 200, a right upper path rectifying piece 240 is embedded in the second flow path R2 between the second upper end opening 220 formed by the packing sheet A-packing sheet B and the heat exchange portion 400 surrounded by the packing sheet A-packing sheet B. The upper end of the right upper path rectifying piece 240 matches the width of the second upper end opening 220, and the width gradually increases from top to bottom, and the lower end corresponds to the width of the heat exchange portion 400 (the first heat exchange portion 402 of the second flow path).

[0078] In this embodiment, the right upper path rectifying piece 240 has a flexural shape in the transverse cross section perpendicular to the stacking direction, and the two sides of the flexural stacking direction, namely, the back side abuts against the front surface of the packing piece B clamping it, and the front side abuts against the rear surface of the packing piece A clamping it. Thus, in the second flow path R2 formed between the second upper end opening 220 and the heat exchange part 400, which is approximately a right-angled trapezoid, a guide portion is formed that guides from the width of the second upper end opening 220 to the full width of the heat exchange part 400 that is approximately the width of the packing pieces A and B.

[0079] [Lower guide section 300]

[0080] At the lower end of the lower guide portion 300, the lower end portions of the packing pieces A and B are alternately arranged to form a guide opening, as described below.

[0081] On one side perpendicular to the stacking direction (the left side in the figure), the lower end of the packing sheet A is offset to one side of the stacking direction (the back side in the figure), while the lower end of the packing sheet B is offset to the opposite side (the front side in the figure), so that in the stacking direction from the front side to the back side in the figure, the lower ends of the left sides of the packing sheet A and the packing sheet B are attached to each other, and the lower ends of the left sides of the packing sheet B and the packing sheet A are open to each other to form a first lower end opening 310. Thus, the first lower end opening 310 is connected to the first flow path R1 formed between the packing sheet B and the packing sheet A.

[0082] On one side (right side in the figure) perpendicular to the stacking direction, the lower end of the packing sheet A is offset to the other side (front side in the figure) in the stacking direction, while the lower end of the packing sheet B is offset to the opposite side (rear side in the figure), so that the lower ends of the left sides of the packing sheet B and the packing sheet A are attached to each other in the stacking direction from the front side to the rear side in the figure, and the lower ends of the left sides of the packing sheet A and the packing sheet B are open to each other to form a second lower end opening 320. Thus, the first lower end opening 320 is connected to the first flow path R2 formed between the packing sheet A and the packing sheet B.

[0083] In the lower guide portion 300, a left lower path rectifying piece 330 is embedded in the first flow path R1 between the first lower end opening 310 formed by the packing piece B-packing piece A and the heat exchange portion 400 surrounded by the packing piece B-packing piece A. The lower end of the left lower path rectifying piece 330 matches the width of the first lower end opening 310, and the width gradually increases from bottom to top, and the upper end corresponds to the width of the heat exchange portion 400.

[0084] In this embodiment, the left lower path rectifying piece 330 has a flexural shape in the transverse cross section perpendicular to the stacking direction, and the flexural back side abuts against the front surface of the packing piece A, and the front side abuts against the rear surface of the packing piece B. Thus, in the first flow path R1 formed between the first lower end opening 310 and the heat exchange part 400, which is approximately an inverted right-angled trapezoid, a guide portion is formed that guides the width of the first lower end opening 310 to the full width of the heat exchange part 400 that is approximately the width of the packing pieces A and B.

[0085] In the lower guide portion 300, a right lower path rectifying piece 340 is embedded in the second flow path R2 between the second lower end opening 320 formed by the packing sheet A-packing sheet B and the heat exchange portion 400 surrounded by the packing sheet A-packing sheet B. The lower end of the right lower path rectifying piece 340 matches the width of the second lower end opening 320, and the width gradually increases from top to bottom, and the lower end corresponds to the width of the heat exchange portion 400.

[0086] In this embodiment, the right lower path rectifying piece 340 has a flexural shape in the transverse cross section perpendicular to the stacking direction, and the flexural back side abuts against the front surface of the packing piece B, and the front side abuts against the rear surface of the packing piece A. Thus, in the second flow path R2 formed between the second lower end opening 320 and the heat exchange part 400, which is approximately an inverted right-angled trapezoid, a guide portion is formed that guides the width of the second lower end opening 320 to the full width of the heat exchange part 400 that is approximately the width of the packing pieces A and B.

[0087] The packing module 1 is formed by alternately stacking the packing sheets A and the packing sheets B, thereby forming the first flow passages R1 and the second flow passages R2 which are isolated from each other and alternately stacked in the packing module 1. The configuration of the first flow passages R1 and the second flow passages R2 will be described in detail below.

[0088] [Unit of the first flow path R1]

[0089] In this embodiment, for the packing module 1, in the stacking direction from the front to the rear in the figure, adjacent packing sheets B and packing sheets A located behind the packing sheets B, that is, packing sheets B-packing sheets A form a unit of the first flow path R1.

[0090] As shown in the figure, the first flow path R1 includes, from top to bottom, a first upper end opening 210 located on the left side of the upper end of the filling module 1; a left upper section guide portion 201 located between the filling sheets B and A and filled by the left upper path straightening sheet 230 and supported; a first heat exchange portion 401 which is a flat cavity formed between the filling sheets B and the filling sheets A in the stacking direction at the heat exchange portion 400; a left lower section guide portion 301 located between the filling sheets B and A and filled by the left lower path straightening sheet 330 and supported; and a first lower end opening 310 located on the left side of the lower end of the filling module 1.

[0091] Thus, in this embodiment, a unit of the first flow path R1 as a flat cavity is formed between adjacent filler sheets B and filler sheets A, and the first upper end opening 210 as its upper end opening and the first lower end opening 310 as its lower end opening are located on the same side perpendicular to the stacking direction.

[0092] [Unit of the second flow path R2]

[0093] In this embodiment, for the packing module 1, in the stacking direction from the front to the rear in the figure, adjacent packing sheets A and packing sheets B located on the rear side of the packing sheets A, that is, packing sheets A-packing sheets B form a unit of the second flow path R2.

[0094] As shown in the figure, the second flow path R2 includes, from top to bottom, a second upper end opening 220 located on the right side of the upper end of the filling module 1; a right upper section guide portion 202 located between the filling sheets A and B and filled by the right upper path straightening sheet 240 and supported; a second heat exchange portion 402 which is a flat cavity formed between the filling sheets A and B in the stacking direction at the heat exchange portion 400; a right lower section guide portion 302 located between the filling sheets A and B and filled by the right lower path straightening sheet 340 and supported; and a second lower end opening 320 located on the right side of the lower end of the filling module 1.

[0095] Thus, in this embodiment, a unit of the first flow path R2 which is a flat cavity is formed between adjacent filler sheets A and B, and the second upper end opening 220 which is the upper end opening and the second lower end opening 320 which is the lower end opening are located on the same side perpendicular to the stacking direction.

[0096] [Heat exchange unit 400]

[0097] The first heat exchange parts 401 and the second heat exchange parts 402 are alternately stacked to form a heat exchange part 400 in which the first flow paths R1 and the second flow paths R2 are alternately stacked to perform intermittent heat exchange.

[0098] [Upper and lower openings of the flow path]

[0099] As described above, in the stacking direction of the packing sheets A and B, the first flow path R1 and the second flow path R2 of the flat cavity are formed between the packing sheet B-packing sheet A and the packing sheet A-packing sheet B, respectively, so that the first flow path R1 and the second flow path R2 are alternately stacked. Therefore, for the packing module 1, the first and second upper end openings 210 and 220 are formed at the upper end edge and are arranged in parallel perpendicular to the stacking direction.

[0100] In this embodiment, as shown in the figure, the first upper end opening 210 is formed on the left side. Since the upper end of the left side of the packing sheet A is biased toward the back side in the figure, and the upper end of the left side of the packing sheet B is biased toward the front side in the opposite figure, the upper ends of the left side of the packing sheet A-packing sheet B are attached to each other, and the upper ends of the left side of the packing sheet B-packing sheet A are open to each other. Thus, the strip-shaped openings of the upper left sides of the packing sheet B-packing sheet A are open to each other, and the upper left sides of the packing sheet A-packing sheet B attached are arranged side by side in the stacking direction to form a complete first upper end opening 210. Without considering the thickness of the packing sheet, it is equivalent to forming an open first upper end opening 210 in the entire area of ​​the upper side of the packing module 1 perpendicular to the stacking direction (the left side in the figure).

[0101] Similarly, the second upper end opening 220 is formed on the right side. Contrary to the first upper end opening 210, the upper right end of the packing sheet B is biased toward the back side in the figure, while the upper right end of the packing sheet A is biased toward the front side in the opposite figure, so the upper right ends of the packing sheet B and the packing sheet A are attached to each other, while the upper right ends of the packing sheet A and the packing sheet B are open to each other. Thus, the strip-shaped openings in which the upper right ends of the packing sheet A and the packing sheet B are open to each other are arranged side by side in the stacking direction through the upper right ends of the attached packing sheet B and the packing sheet A to form a complete second upper end opening 220. Without considering the thickness of the packing sheet, it is equivalent to forming an open second upper end opening 220 in the entire area of ​​the other side (the right side in the figure) of the upper end of the packing module 1 perpendicular to the stacking direction.

[0102] On the other hand, the first and second upper openings 210 and 220 are formed at the lower edge and arranged side by side in a direction perpendicular to the stacking direction.

[0103] In this embodiment, as shown in the figure, the first lower end opening 310 is formed on the left side. Since the lower left end of the packing sheet A is biased toward the back side in the figure, and the lower left end of the packing sheet B is biased toward the front side in the opposite figure, the lower left ends of the packing sheets A and B are attached to each other, while the lower left ends of the packing sheets B and A are open to each other. Thus, the strip-shaped openings in which the lower left ends of the packing sheets B and A are open to each other are arranged side by side in the stacking direction through the lower left ends of the attached packing sheets A and B, forming a complete first lower end opening 310. Without considering the thickness of the packing sheet, it is equivalent to forming an open first lower end opening 310 in the entire area of ​​the side (left side in the figure) of the lower end of the packing module 1 perpendicular to the stacking direction.

[0104] Similarly, the second lower end opening 320 is formed on the right side. Contrary to the first lower end opening 310, the lower right end of the packing sheet B is biased toward the back side in the figure, while the lower right end of the packing sheet A is biased toward the front side in the opposite figure, so the lower right ends of the packing sheet B and the packing sheet A are attached to each other, while the lower right ends of the packing sheet A and the packing sheet B are open to each other. Thus, the strip-shaped openings in which the lower right ends of the packing sheet A and the packing sheet B are open to each other are arranged side by side in the stacking direction through the attached lower right ends of the packing sheet B and the packing sheet A, forming a complete second lower end opening 320. Without considering the thickness of the packing sheet, it is equivalent to forming an open second lower end opening 320 in the entire area of ​​the other side (the right side in the figure) of the lower end of the packing module 1 perpendicular to the stacking direction.

[0105] [Opening of flow path]

[0106] The first flow path R1 will be described in further detail from top to bottom.

[0107] As described above, the first flow path R1 is formed at the upper end of the packing module 1, which is equivalent to forming a first upper end opening 210 in the entire left area perpendicular to the stacking direction, and at the first upper end opening 210, the portion where the upper left ends of the packing sheet A-packing sheet B are bonded to each other is divided into a plurality of units. In the upper left guide section 201, after passing downward through the portion where the upper left ends of the packing sheet A-packing sheet B are bonded to each other, the units of the first flow path R1 are separated from each other in the stacking direction, and on the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases perpendicular to the stacking direction to approximately the width of the packing sheets A and B to form a flat shape, that is, the thickness decreases and the width increases, and the units of the first heat exchange section 401 that enter the flat heat exchange space defined by the packing sheet B-packing sheet A of the heat exchange section 400 from the upper guide section 200.

[0108] When continuing downward from the heat exchange section 400 to the lower guide section 300, in contrast to the situation in the upper guide section 200, the unit of the first flow path R1 moves downward from a flat shape having approximately the width of the fillers A and B, gradually increasing in size in the stacking direction on the one hand, and gradually decreasing in size perpendicular to the stacking direction to the width of the second lower end opening 220 on the other hand, that is, the thickness increases and the width decreases, and in the lower left guide section 301, the left lower end portions of the fillers A and B converge at the part where they are attached to each other, and reach the first lower end opening 310.

[0109] Therefore, in the first flow path R1 , the flow path cross-sectional area of ​​the entire flow path from the first upper end opening 210 through the upper guide portion 200 , the heat exchange portion 400 , the lower guide portion 300 to the first lower end opening 310 theoretically does not change substantially.

[0110] The second flow path R2 has a rotationally symmetrical structure with the first flow path R1, which will be described in detail below.

[0111] As described above, the second flow path R2 is formed at the upper end of the packing module 1, which is equivalent to forming a second upper end opening 210 in the entire right area perpendicular to the stacking direction, and at the second upper end opening 210, the portion where the upper right end portions of the packing sheet B and the packing sheet A are bonded to each other is divided into a plurality of units. In the right upper section guide 202, after passing downward through the portion where the upper right end portions of the packing sheet B and the packing sheet A are bonded to each other, the units of the first flow path R1 are separated from each other in the stacking direction, and on the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases perpendicular to the stacking direction to approximately the width of the packing sheets A and B to form a flat shape, that is, the thickness decreases and the width increases, and the units of the second heat exchange section 402 that enter the flat heat exchange space defined by the packing sheets A and the packing sheets B of the heat exchange section 400 from the upper section guide 200.

[0112] When continuing downward from the heat exchange section 400 to the lower guide section 300, in contrast to the situation in the upper guide section 200, the unit of the second flow path R2 moves downward from a flat shape having approximately the width of the fillers A and B, gradually increasing in size in the stacking direction on the one hand, and gradually decreasing in size perpendicular to the stacking direction to the width of the second lower end opening 220 on the other hand, that is, the thickness increases and the width decreases, and in the right lower guide section 302, the right side lower ends of the fillers B and fillers A converge with each other to reach the second lower end opening 320.

[0113] Therefore, in the second flow path R2, the flow path cross-sectional area of ​​the entire flow path from the second upper end opening 220 through the upper guide portion 200, the heat exchange portion 400, the lower guide portion 300 to the second lower end opening 320 theoretically does not change substantially.

[0114] As described above, in this embodiment, the first and second upper openings 210 and 220, which are the upper openings of the first and second flow paths R1 and R2, have a total opening area that is consistent with the total flow path cross-sectional area of ​​each portion from top to bottom. Similarly, the first and second lower openings 310 and 320, which are the lower openings of the first and second flow paths R1 and R2, have a total opening area that is consistent with the total flow path cross-sectional area of ​​each portion from top to bottom, that is, the opening areas of 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 flow rate and flow efficiency of each flow path R1 and R2 and reducing the resistance of the packing module 1, which will be further described in detail later.

[0115]

Rectifier

[0116] In this way, when the straightening pieces 230, 240, 330, 340 are embedded in each guide part 201, 202, 301, 302, that is, the straightening pieces 230, 240, 330, 340 are embedded in their respective first and second flow paths R1, R2, since each straightening piece 230, 240, 330, 340 is formed in a flexural shape, and the extension direction of the flexural protrusion corresponds to the extension path of the first and second flow paths R1, R2, the thickness of each straightening piece 230, 240, 330, 340 is far different from the flow path cross-sectional area of ​​the first and second flow paths R1, R2, and therefore will not affect the passing efficiency of the first and second flow paths R1, R2.

[0117] In addition, in the present embodiment, the first upper end opening 210 and the second upper end opening 220, which are the upper end openings of the first and second flow paths R1 and R2, are arranged side by side at right angles to the stacking direction and have approximately the same width, so that the left upper path straightening piece 230 and the right upper path straightening piece 240, which are respectively located in the left upper section guide portion 201 and the right upper section guide portion 202, have approximately the same structure of their accommodation spaces and are arranged in a rotationally symmetrical manner, so that the same components can be used to constitute the left upper path straightening piece 230 and the right upper path straightening piece 240.

[0118] Similarly, the first lower end opening 310 and the second lower end opening 320, which are the lower end openings of the first and second flow paths R1 and R2, are arranged side by side at right angles to the stacking direction and have approximately the same width, so that the left lower path straightening piece 330 and the right lower path straightening piece 340, which are respectively located in the left lower section guide portion 301 and the right lower section guide portion 302, have approximately the same structure of their accommodation spaces and are arranged in a rotationally symmetrical manner, so the same components can be used to constitute the left lower path straightening piece 330 and the right lower path straightening piece 340.

[0119] Furthermore, in this embodiment, by making the height of the upper guide 200 and the lower guide 300 substantially the same, the structures of the receiving spaces of the rectifying pieces 230, 240, 330, 340 are substantially the same, so that the same components can be used to constitute the upper left rectifying piece 230, the upper right rectifying piece 240, the lower left rectifying piece 330, and the lower right rectifying piece 340. In this way, when manufacturing the packing module 1, only the packing piece A, the packing piece B, and the common rectifying piece are needed, so that the production cost of the packing module 1 is significantly reduced and the assembly efficiency is significantly improved.

[0120]

Cooling Tower 10

[0121] Fig.10 This is a schematic diagram of a cooling tower manufactured based on the filler module 1 of this embodiment.

[0122] The bottom layer of the cooling tower 10 is an air intake layer 101, and a plurality of dampers 102 are arranged around the air intake layer 101. A packing layer 103 is arranged above the air intake layer 101, and the packing layer 103 is arranged in a matrix shape on a horizontal plane by a plurality of packing modules 1. A spraying part 104 is arranged above the packing layer 103, and the spraying part 104 sprays the hot water to be treated to each packing module 1 of the packing layer 103. A partition 105 extending along the stacking direction of the packing module 1 is roughly vertically arranged in the area between the spraying part 104 and the packing layer 103, and a plurality of partition spaces 105a and 105b are surrounded by the partition 105 and the top surface of the packing module 1, wherein the partition space 105a is used as a spraying space for spraying hot water, and the partition space 105b is used as an air induction space for sucking gas from bottom to top. The spray space 105a and the air entrainment space 105b are alternately arranged in a direction perpendicular to the stacking direction of the matrix composed of the filling modules 1, and each partition 105 is arranged at the intersection of the first upper end opening 210 and the second upper end opening 220 of the filling module 1, thereby separating the first flow path R1 and the second flow path R2 connected to the first upper end opening 210 and the second upper end opening 220.

[0123] Above the spray section 104 is the exhaust layer 106, and above the exhaust layer 106 is an exhaust port 108 provided with a fan 107. The fan 107 draws air upward, so that cold air enters the air intake layer 101 from the damper 102 in the lower layer of the cooling tower 10, passes upward through each packing module 1 of the packing layer 103, passes through the spray space 105a and the air intake space 105b respectively, is further mixed in the exhaust layer 106, and is discharged upward through the exhaust port 108.

[0124] On the other hand, the hot water to be treated sprayed from the spraying part 104 to each packing module 1 of the packing layer 103 is cooled by each packing module 1 and falls to the bottom surface of the air inlet layer 101. The cooled water is recovered through the collection equipment for recycling in the factory.

[0125] Working status 1:

[0126] As described above, the cooling tower 10 is set to the winter working state. At this time, the hot water to be treated sprayed from the spray part 104 is confined in 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 arranged at the intersection of the first upper end opening 210 and the second upper end opening 220 relative to the packing module 1, the first and second flow paths R1 and R2 adjacent to each other between two adjacent packing modules 1 both form a water flow path Rw, and the outer flow paths R1 and R2 are respectively adjacent to the second and first flow paths adjacent to both sides, and both form an air flow path Ra.

[0127] In the water flow path Rw, the spray water flows into the packing module 1, passes through the upper guide part 200, and forms a water film distributed in the heat exchange part 400 in a flat space of substantially the entire width of the packing module 1 and attached to the wall surfaces on both sides of the stacking direction of the flat space. The adjacent flow paths on both sides in the stacking direction serve as air flow paths Ra, which perform heat exchange with the hot water in the water flow path Rw through the wall surfaces of the packing sheets A and B.

[0128] When the cooling tower 10 is working in winter, the air sucked into the air flow path Ra from the bottom of the packing module 1 is dry cold air with low air temperature and low water content. When heat exchange occurs with hot water in the air flow path Ra passing through the packing module 1, the heat exchange is completed in an independent flow path completely separated by the packing sheets A and B. Therefore, when it is discharged from the top of the packing module 1, the temperature rises, but the water content at this time does not change, that is, dry hot air is formed.

[0129] On the other hand, since there is hot water sprayed from the spraying part 104 above in the water flow path Rw, the air sucked by the fan 107 in the water flow path Rw encounters a large resistance, so the air flow rate is very small compared to the air flow through the air flow path Ra, usually only a few. The air flowing through the water flow path Rw will form hot saturated air, that is, hot and humid air.

[0130] The dry hot air flowing through the air flow path Ra and the humid hot air flowing through the water flow path Rw are mixed in the exhaust layer 106. Since there is less humid hot air, unsaturated hot air is formed after mixing with the dry hot air. After being discharged into the atmosphere through the fan 107 and the exhaust port 108, the unsaturated hot air is gradually cooled and less water is precipitated, thereby greatly reducing the amount of fog formed.

[0131] In this embodiment, by switching the spray part 104, the spray space 105a and the air entrainment space 105b can be flexibly switched, that is, stop spraying hot water on the spray space 105a, and spray hot water on the air entrainment space 105b. In this way, the functions of the spray space 105a and the air entrainment space 105b can be swapped. On the one hand, the normal operation of the cooling tower 10 can be guaranteed, and on the other hand, the flow path R1 or R2 of the packing module 1 connected to the air entrainment space 105b can be effectively cleaned and maintained, so that when the cooling tower 10 is cleaned and maintained, the normal operation of the cooling tower 10 is not affected.

[0132] Working status 2:

[0133] When working in summer, the spraying part 104 can be adjusted to spray hot water to the bleed space 105b and the spraying space 105a in the same manner, so as to ensure that the cooling tower 10 has the heat exchange efficiency as high as possible without fogging in summer.

[0134]

Cooling Tower 20

[0135] In this embodiment, the filler module 1 is still used as the cooling tower 20, and only the differences from the cooling tower 10 are described in detail, and the same structures are not repeated.

[0136] The cooling tower 20 of this embodiment is different from the above cooling tower 10 in that, for each spraying space 105a, a cover plate 109 is further arranged roughly horizontally on the upper part of the partition 105 along the stacking direction of the packing module 1. A plurality of partition spaces 205a and 205b are enclosed by the cover plate 109, the partition 105 and the packing module 1. In this embodiment, the cover plate 109 is only arranged in the spraying space 205a for spraying hot water, and the cover plate 109 is not arranged for the air intake space 205b for exhausting air; of course, the cover plate 109 can also be arranged for both the spraying space 105a and the air intake space 205b, and the cover plate 109 can be arranged in a continuous plate shape or a combination of multiple plates, and the cover plate 109 can be turned over or turned in half along the partition 105 on one side or both sides to form a detachable or openable manner, so that the spraying space 205a and the air intake space 205b can be switched.

[0137] Working status 1:

[0138] This working state is particularly suitable for winter in northern my country. In this state, the working process of the cooling tower 20 is similar to that of the above-mentioned cooling tower 10, except that a cover plate 109 is provided above the spray space 205a. Therefore, the spray space 205a does not play the role of air entrainment in principle, and only hot water passes 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 the cooling tower 20, there is only dry hot air from the air entrainment space 205b.

[0139] Therefore, from the cooling tower 20, only dry hot air is sucked by the fan 107 and discharged from the exhaust port 108, so that the moisture in the hot air discharged from the cooling tower 20 is reduced as much as possible, thereby further improving the defogging ability of the cooling tower 20 in winter. Moreover, since the discharged air is only dry hot air, the amount of moisture discharged from the cooling tower 20 is also less, which is more conducive to water saving.

[0140] When both the spray space 205a and the bleed air space 205b are provided with openable and closable (flat opening, split opening or removable) covers 109, by opening the cover above the spray space 205a and closing the cover above the bleed air space 205b, and adjusting the spray part 104, the functions of the spray space 205a and the bleed air space 205b can be exchanged in the same way as the above-mentioned cooling tower 10, and the flow path R1 or R2 of the filling module 1 corresponding to the original bleed air space 205b can be cleaned, thereby avoiding shutdown of the cooling tower 20.

[0141] 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 substantially the same.

[0142] Working status 2:

[0143] In the summer working state, by removing or opening the cover 109 above the spray space 205a, the spray part 104 is adjusted so that hot water is sprayed to the induced air space 205b and the spray space 205a in the same way, so that the cooling tower 20 can achieve the same working state of improving the heat exchange efficiency in summer as the above-mentioned cooling tower 10.

[0144] In the cooling tower 20 of the present embodiment, the cover plate 109 arranged above the partition spaces 205a, 205b is a flat plate, but is not limited thereto. It can also be a plate extending toward the middle from the partition plates 105 on both sides of the stacking direction of the filling modules 1 of the partition spaces 205a, 205b, and overlapping to close the partition spaces 205a, 205b, forming an upward or downward vertex angle at the overlapping portion, that is, as long as the upper part of the partition spaces 205a, 205b can be closed, there is no limitation on the configuration of the cover plate 109.

[0145] In the above embodiment, the flow straightening piece 230 is provided in the upper left guide portion 201 of the upper guide portion 200 of the first flow path R1 formed between the packing piece B and the packing piece A in the stacking direction of the packing modules 1 .

[0146] Furthermore, the flow straightening piece 240 is provided in the right upper stage guide portion 202 formed between the packing piece A and the packing piece B in the stacking direction of the upper stage flow guide portion 200 of the second flow path R2.

[0147] On the other hand, the flow straightening piece 330 is provided in the left lower stage guide portion 301 formed between the packing piece B and the packing piece A in the stacking direction of the lower stage flow guide portion 300 of the first flow path R1.

[0148] Furthermore, the flow straightening piece 340 is provided in the right upper stage guide portion 202 formed between the packing piece A and the packing piece B in the stacking direction of the lower stage flow guide portion 300 of the second flow path R2.

[0149] Since the first upper opening 210 and the second upper opening 220 respectively occupy approximately half of the width of the packing module 1, in fact, the rectifying piece 230 is embedded in the approximately right-angled trapezoidal area enclosed by the approximately middle of the upper edge of the packing piece B-packing piece A, downward through the left edge of the upper guide part 200, and then along the lower end line of the side upper guide part 200 to the right to the right edge of the upper guide part 200, and then obliquely upward to the approximately middle of the upper edge of the packing piece A (B). For the packing piece A, it is biased to the rear side at the right-angled trapezoidal area, and on the contrary, for the packing piece B, it is biased to the front side, so that, in the stacking direction, the front packing piece A and the rear packing piece B, that is, the packing piece A-packing piece B, form a close combination at the periphery of the first upper opening 210, so the width of the opening in the stacking direction between the front packing piece B and the rear packing piece A, the packing piece B-packing piece A at the first upper opening 210 is 2d. That is to say, in the area of ​​the right-angled trapezoid, the distance in the stacking direction at the first upper end opening 210 at the upper end is approximately 2d, and the distance in the stacking direction at the part where the lower end is connected to the heat exchange part 400 is the interval d between the filler sheets A and B, thereby forming a space for the upper left section guide part 201.

[0150] The cross section of the rectifying piece 230 in the horizontal direction is in a folded shape extending perpendicular to the stacking direction. The upper portion near the first upper end opening 210 has a large folding amplitude and a small folding span. In the process of extending from top to bottom toward the heat exchange portion 400, the folding amplitude gradually decreases and the folding span gradually increases to fill the space of the left upper section guide portion 201. By making the rectifying piece 230 fold in the horizontal direction, a plurality of guide flow paths from the first upper end opening 210 to the heat exchange portion 400 are formed. Each guide flow path is thick in the stacking direction at the upper end and small in the horizontal direction, and a flow path with a small thickness and a large width at the lower end, so that the hot water flowing in from the first upper end opening 210 with a width of approximately half of the packing module 1 can be effectively and evenly guided to the heat exchange portion 400 with a width of approximately the full width of the packing module 1. In addition, whether it is a single guide flow path or an overall guide flow path, the cross-sectional area change of the guide flow path from top to bottom is as small as possible to reduce the resistance of the fluid. Good passing efficiency can be achieved for hot water sprayed from above and air sucked from below.

[0151] The rectifying piece 240 located in the space of the right upper stage guide portion 202 has the same structure, except that the arrangement position is rotationally symmetrical with respect to the rectifying piece 240 in the horizontal direction.

[0152] The rectifying pieces 330 and 340 are respectively arranged in the same manner as the upper left guide portion 201 and the upper right guide portion 202 located in the upper guide portion 200, in a left lower guide portion 301 formed by offsetting the inverted right-angled trapezoidal area of ​​the filler sheet B-filler sheet A at the lower guide portion 300 toward the outside in the stacking direction, and in a right lower guide portion 302 formed by offsetting the inverted right-angled trapezoidal area of ​​the filler sheet A-filler sheet B at the lower guide portion 300 toward the outside in the stacking direction. The rectifying pieces 330 and 340 respectively form a plurality of flow paths in the lower left guide section 301 and the lower right guide section 302, each of which has a small thickness at the upper end in the stacking direction and a large width in the horizontal direction, and a large thickness and small width at the lower end, so as to guide water from the heat exchange section 400 of the approximately full width of the first and second flow paths R1 and R2 of the filling module 1 to the first and second lower end openings 310 and 320 of approximately half the width.

[0153] That is, for the rectifying pieces 330 and 340, they are inverted, with a large bending amplitude and a small bending span at the first and second lower end openings 310 and 320. In the process of extending from bottom to top toward the heat exchange part 400, the bending amplitude gradually decreases and the bending span gradually increases.

[0154] The flow straightening piece 330 located in the space of the left lower stage guide portion 301 and the flow straightening piece 340 located in the space of the right lower stage guide portion 302 are similarly rotationally symmetric in the horizontal direction.

[0155] Therefore, when the first and second upper openings 210, 220 and the first and second lower openings 310, 320 are both approximately half the width of the filling module 1, if the vertical lengths of the upper and lower section guides 200, 300 are made the same, the left upper section guide 201, the right upper section guide 202, the left lower section guide 301, and the right lower section guide 302 can form a rotationally symmetrical structure, so that the straightening pieces 230, 240, 330, 340 can be the same components, so that the filling module 1 only needs three components when it is manufactured, namely, the filling piece A, the filling piece B and the universal straightening piece. This not only significantly reduces the mold cost and the component production cost for manufacturing the filling module 1, but also when assembling the filling piece A, the filling piece B and the straightening piece, there is no need to consider the model differences of the straightening pieces, which makes assembly convenient, thereby greatly reducing the overall production cost of the filling module 1.

[0156] According to the above preferred embodiment, by offsetting and fitting the filling sheet A and the filling sheet B in the upper guide portion and the lower guide portion respectively, the first upper end opening, the second upper end opening, the first lower end opening and the second lower end opening are respectively stacked in the stacking direction, and without considering the thickness of the filling sheets A and B, the total size of the openings in the stacking direction is roughly consistent with the stacking thickness of the filling module in the stacking direction.

[0157]

Cooling Tower 30

[0158] Fig.12 It is a structural schematic diagram of an old tower in some prior arts; Fig.13 It is a top view of an old tower in some prior art.

[0159] like Fig.12 and Fig.13 As shown in FIG. 1 , the old tower includes a main tower body, and a water receiving structure 110 for collecting water is provided at the bottom thereof. The bottom layer of the main tower body is an air intake layer 101. When the main tower body is a single tower, a plurality of air gates 102 are provided around the air intake layer 101. When the main tower body is a plurality of tower bodies arranged continuously, as shown in FIG. Fig.13 As shown, the dampers 102 are formed at the bottom of both sides of the main tower body in the width direction. In the drawings, W represents the width scheme, and L represents the length direction (the same below).

[0160] A packing layer 303' is provided above the air intake layer 101. The packing layer 303' may be, for example, an S-wave packing, an oblique staggered packing, a stepped trapezoidal oblique wave packing, a differential sine wave packing, a point wave packing, a hexagonal honeycomb packing, a bidirectional wave packing, an oblique folded wave packing or other conventional packing. The function of conventional packing in a cooling tower is to increase the heat dissipation, prolong the residence time of cooling water, increase the heat exchange area, and increase the heat exchange amount. An exhaust port 108 of a fan 107 is provided at the top of the main tower body. The fan 107 draws air upward, so that cold air enters the air intake layer 101 from the damper of the lower layer of the cooling tower 10. When the cold air passes through the packing layer 303', it exchanges heat with the hot water showered by the spray part 304', and is finally discharged from the exhaust port 108.

[0161] However, as the load continues to increase, the old cooling tower currently in use faces the problem of insufficient heat dissipation capacity, and completely dismantling and rebuilding it will incur high costs, and the water collection part 110 on the ground needs to be dismantled during dismantling, which also increases the workload and prolongs the construction period. Therefore, it is necessary to renovate the old cooling tower to improve its heat dissipation capacity.

[0162] Fig.14 It is a schematic diagram of the structure of the old cooling tower after transformation;

[0163] like Fig.14As shown, the cooling tower body of the modified cooling tower 30 includes the original main tower body 330. The width direction (i.e. Fig.14 The original walls 330a and 330b on both sides (in the middle W direction) above the air inlet layer 101 are demolished, and expansion parts 340a and 340b are built outward. The construction of the expansion parts 340a and 340b increases the internal space of the cooling tower, especially the size in the width W direction. The packing layer 303 in the expansion parts 340a and 340b can be filled with more packing, and a water supply pipe and a nozzle are installed above the newly added packing, which can increase the heat dissipation area of ​​the cooling tower 30, thereby improving the heat dissipation capacity of the cooling tower 30.

[0164] It should be noted that the above-mentioned expansion portion can be selectively formed only on one side of the main tower body 330 according to different site conditions, that is, only the expansion portion 340a or the expansion portion 340b is constructed.

[0165] The following description will be made by taking the expanded portion 340b as an example. A water receiving structure 307 is placed at the bottom of the expanded portion 340b, and the water receiving structure 307 is used to receive water sprayed from the spray head in the spraying portion 304 in the expanded portion 340b. An upper air inlet 311 is provided on the side wall between the water receiving structure 307 and the packing layer 303, and the upper air inlet 311 is used to supply airflow to the newly added part of the packing layer 303.

[0166] A drainage portion 309 is installed on the water receiving structure 307, and the drainage portion 309 extends from the water receiving structure 307 to the inside of the cooling tower 30. The drainage portion 309 is used to discharge the water in the water receiving structure 309 to the water collecting portion 110 at the bottom of the cooling tower 30. The water receiving structure can be, for example, a water receiving pipe or a water tank, one end of which is connected to the drainage portion 309, and the other end of which extends to the inside of the cooling tower 30.

[0167] In order to improve the strength of the expanded portion 340b, a support portion 308 is provided at the lower portion of 340b. The support portion 308 may be, for example, a support column, the upper end of which is connected to the bottom of the expanded portion 340b and the lower end of which is connected to the ground.

[0168] In this embodiment, by constructing the expansion parts 340a and 340b on the outside of the main tower body 330 in the width direction, the heat dissipation area and heat dissipation capacity of the cooling tower 30 can be increased under the premise of limited engineering workload, and the original water collection part 110 at the bottom of the cooling tower 30 can be used to collect water without dismantling and expanding the water collection part 110, which also reduces the engineering workload and renovation and expansion costs accordingly.

[0169] In the above reconstruction scheme, the height space of the main tower body 330 remains unchanged, and there is insufficient space on the upper side of the spray section 304 to install the demisting module. In winter, "white fog" is easily formed on the upper side of the exhaust port 108, resulting in a waste of water resources.

[0170] Fig.15 It is an embodiment of applying the filler module of the utility model in the reconstruction of an old cooling tower;

[0171] To solve the above problems, Fig.15 As shown, in this embodiment, the packing modules 1 are placed in the expansion parts 340a and 340b of the cooling tower 30. In the expansion parts 340a and 340b, the spray part 304 sprays the hot water to be treated to each packing module 1 of the packing layer 303. A partition 305 extending along the stacking direction of the packing module 1 is roughly vertically arranged in the area between the spray part 304 and the packing layer 303, and a plurality of partition spaces 305a and 305b are surrounded by the partition 305 and the top surface of the packing module 1, wherein the partition space 305a is used as a spray space for spraying hot water, and the partition space 305b is used as an air intake space for sucking gas from bottom to top. The spray space 305a and the air entrainment space 305b are alternately arranged in a direction perpendicular to the stacking direction of the matrix composed of the filling modules 1, and each partition 305 is arranged at the intersection of the first upper end opening 210 and the second upper end opening 220 of the filling module 1, thereby separating the first flow path R1 and the second flow path R2 connecting the first upper end opening 210 and the second upper end opening 220.

[0172] Above the spraying part 304 is the exhaust layer 306. Above the exhaust layer 306 is the exhaust port 108 provided with the fan 107. The fan 107 draws air upward, so that the cold air enters the air intake layer 101 from the damper 102 at the lower layer of the cooling tower 30, and goes upward through the packing layer 303. At the same time, under the suction of the fan 107, the cold air enters the lower space of the packing layer 303 in the expansion part 340b from the upper air inlet 311, goes upward through each packing module 1, passes through the spraying space 305a and the air induced space 305b respectively, is further mixed in the exhaust layer 306, and is discharged upward through the exhaust port 108.

[0173] In addition, the hot water to be treated sprayed from the spraying part 304 to the original filler 312 of the filler layer 303 falls into the water collecting part 110 after being cooled by the original filler 312 for recycling in the factory. In the expansion parts 340a and 340b, the hot water to be treated sprayed from the spraying part 304 to each filler module 1 of the filler layer 303 falls into the water receiving structure 307 after being cooled by each filler module 1, and is discharged to the water collecting part 110 through the drainage part 309.

[0174] It should be noted that during the renovation of the old cooling tower, the original filler 312 can be removed and replaced with new ordinary filler, or the original filler 312 can be used without replacement; the pipes and nozzles of the spray part 304 above the original filler 312 can also be removed and replaced, or not.

[0175] Within the range of the expanded portions 340 a and 340 b , the extending direction of the pipeline in the spray portion 303 is the same as the extending direction of the partition plate 305 .

[0176] In addition, the structure of the cooling tower can also be used as a construction plan for a new cooling tower, and is not limited to the renovation of an old cooling tower.

[0177] Working status 1:

[0178] As described above, the cooling tower 30 is set to the winter working state. At this time, the hot water to be treated sprayed from the spray part 304 is confined to one of the two flow paths entering the packing module 1 in the spray space 305a. In this embodiment, since the partition 305 is arranged at the intersection of the first upper end opening 210 and the second upper end opening 220 relative to the packing module 1, the first and second flow paths R1 and R2 adjacent to each other between two adjacent packing modules 1 both form water flow paths Rw, and the outer flow paths R1 and R2 are respectively adjacent to the second and first flow paths adjacent to both sides, and both form air flow paths Ra.

[0179] In the water flow path Rw, the spray water flows into the packing module 1, and is formed in the heat exchange part 400 through the upper guide part 200 as a water film attached to the wall surfaces on both sides of the stacking direction in the flat space in the substantially full width of the packing module 1. The adjacent flow paths on both sides of the stacking direction are the air flow paths Ra, which perform heat exchange with the hot water in the water flow path Rw through the wall surfaces of the packing sheets A and B.

[0180] When the cooling tower 30 is working in winter, the air sucked into the air flow path Ra from the bottom of the packing module 1 is dry cold air with low air temperature and low water content. When heat exchange occurs with hot water in the air flow path Ra passing through the packing module 1, the heat exchange is completed in an independent flow path completely separated by the packing modules A and B. Therefore, when discharged from the top of the packing module 1, the temperature rises, but the water content at this time does not change, that is, dry hot air is formed.

[0181] On the other hand, since there is hot water sprayed from the spray part 104 above in the water flow path Rw, the air sucked by the fan 107 in the water flow path Rw encounters a large resistance, so the air flow rate is very small relative to the air flow through the air flow path Ra, usually only a few. The air flowing through the water flow path Rw will form hot saturated air, that is, hot and humid air.

[0182] The dry hot air flowing through the air flow path Ra, the humid hot air flowing through the water flow path Rw, and the humid hot air formed by the original filler in the main tower body 330 are mixed in the exhaust layer 306. The dry hot air and the humid hot air are mixed 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 and the precipitated water is reduced, thereby reducing the amount of fog formed.

[0183] Working status 2:

[0184] When working in summer, the spraying part 304 can be adjusted to spray hot water to the induced air space 305b and the spraying space 305a in the same manner, so as to ensure that the cooling tower 30 has no fogging problem in summer and improve the heat exchange efficiency as much as possible.

[0185] Therefore, by installing the filler module 1 in the expanded parts 340a and 340b, the heat dissipation area is increased and the water saving and mist elimination effect is played, which is of great significance in the reconstruction of old cooling towers.

[0186]

Cooling Tower 40

[0187] In this embodiment, the filler module 1 is still used as the cooling tower 40, and only the differences from the cooling tower 30 are described in detail, and the same structures are not repeated.

[0188] Fig.16 Another embodiment of applying the filler module of the utility model in the reconstruction of an old cooling tower; Fig.17 yes Fig.16 Partial cross-sectional view of EE.

[0189] like Fig.16 and Fig.17 As shown, the cooling tower 40 of this embodiment is different from the above cooling tower 30 in that the arrangement direction of the packing modules 1 is different in the expansion part 340a and the expansion part 340b. In this embodiment, the stacking direction of the packing sheets in the packing module 1 is parallel to the width direction of the cooling tower 40. In the expansion parts 340a and 340b, as shown in FIG. Fig.17 As shown, the arrangement of the packing module 1, the partition 405, the spray space 405a, and the bleed air space 405b is similar to that of the packing module 1, the partition 105, the spray space 105a, and the bleed air space 105b in the cooling tower 10, except that the extension length of the packing module 1 along the stacking direction of the packing sheets in the cooling tower 40 is limited to the expansion part 340a and / or 340b. Similarly, the arrangement of the packing module 1 in the expansion parts 340a and 340b in the cooling tower 40 in this embodiment increases the heat dissipation area while playing a role in water saving and mist elimination.

[0190] In addition, if Fig.16 As shown, the support portion 308 in the cooling tower 40 extends along the inclined direction, and the upper end of the support portion 308 is connected to the bottom of the water receiving structure 307. The lower end of the support portion 308 is connected to the side wall of the cooling tower 40. The support portion 308 of this structure can also support the water receiving structure 307 and the expansion portions 340a and 340b. The support portion 308 can also be other structures that support the expansion portions 340a and 340b, which will not be repeated.

[0191]

Cooling Tower 50

[0192] In this embodiment, the filler module 1 is still used as the cooling tower 50, and only the differences from the cooling tower 40 are described in detail, and the same structures are not repeated.

[0193] Fig.18 It is another embodiment of applying the filler module of the utility model in the reconstruction of an old cooling tower; Fig.19 yes Fig.18 Middle FF cross-sectional view.

[0194] like Fig.18 and Fig.19 As shown, the filler module 1 substantially fills the inner space of the cooling tower 50 along the width direction of the cooling tower 50. The stacking direction of the filler sheets in the filler module 1 is parallel to the width direction of the cooling tower 50.

[0195] In this embodiment, if Fig.19 As shown, the arrangement of the filler module 1, the partition 505, the spray space 505a, and the bleed air space 505b is the same as that of the filler module 1, the partition 105, the spray space 105a, and the bleed air space 105b in the cooling tower 10.

[0196]

Water receiving structure 307

[0197] Such as 20 and Fig.21 A schematic diagram of a water receiving structure according to an embodiment is shown.

[0198] like Fig. 20 and Fig.21 As shown, the water receiving structure 307 includes a plurality of units 307a arranged in the horizontal direction. The number of units 307a arranged and installed is determined according to the direction L of the cooling tower (reference Fig.13 ). Compared with setting the water receiving structure as an integrated tank body, the technical solution of forming the water receiving structure 307 by arranging a plurality of monomers 307a has multiple advantages: it is easy to manufacture in the factory, realizes the standardization and mass production of the monomers 307a, and matches the appropriate number of monomers 307a according to the installation requirements.

[0199] The middle part of the monomer 307a is concave to form a groove 3071. One side edge of the monomer 307a in the width direction extends upward and is higher than the other side edge and deflects outward (away from the groove 3071) and downward to form a lap joint 3074. When multiple monomers 307a are arranged together, the other side edge of one monomer 307a that is not provided with a lap joint 3074 is placed under the lap joint 3074 of the adjacent monomer 307a, which prevents water from flowing down from the gap between the two monomers 307a.

[0200] The groove body 3071 extends along the length direction of the single body 307a, one end of which is closed by the water retaining plate 3072, and the other end is open to form a drainage portion 309. The water flowing into the groove body 3071 flows out from the drainage portion 309 into the water collecting portion 110.

[0201] In this embodiment, the bottom of the groove body 3071 has an arc-shaped structure, but is not limited thereto. The bottom may also be a pointed structure or a polygonal structure.

[0202]

Water receiving structure 407

[0203] The water receiving structure 407 in this embodiment is further improved on the basis of the water receiving structure 307. In this embodiment, the structure of the monomer 407a of the water receiving structure 407 is different from that of the monomer 307a.

[0204] Specifically, Fig. 22 and Fig.23 As shown, in this embodiment, the lower end of the groove 4071 in the single body 407a has an angular structure, and the angular structure can be formed by bending a plate, for example, and can be an acute angle, an obtuse angle or a right angle. Fig.23 As shown, based on the angular structure of the monomer 407a of this embodiment, multiple monomers 407a can be stacked together during transportation or storage, thereby reducing the volume occupied during transportation. Fig. 22 As shown, an air inlet passage 4075 is formed on the lower side of the water receiving structure 407, and the air inlet passage 4075 is used to replenish air into the cooling tower.

[0205] One end of the trough 4071 is closed by a water retaining plate 4072, and the other end is opened to form a drainage portion 409. Hot water falling from the upper packing layer falls into the trough 4071 and is discharged from the drainage portion 409 to the water collecting portion 110 at the bottom of the cooling tower.

[0206] The water connection structure of the preferred embodiment of the utility model and the modified cooling tower with the water connection structure are described in detail above, but those skilled in the art can make various modifications, changes, combinations, etc. on this basis, and these modifications, changes, and combinations all fall within the scope of protection of the claims of this application.
