Description

TECHNICAL FIELD

[0001] The present application relates to a module of a cooling tower, in particular to a filler assembly in the cooling tower. BACKGROUND

[0002] The cooling tower filler module separates the downward hot water flow path and the upward cold air flow path, the hot water flows into the opening formed in a part of the width of the upper end of the filler module, and the opening for the air flow is formed in another part of the width of the upper end of the filler module.

[0003] In some construction schemes, the filler sheets are assembled into an integral filler assembly in the factory, and then the filler assembly is transported to the construction site and installed in the cooling tower in an integral hoisting manner, which causes the filler assembly to have a large size and is inconvenient for construction, transportation and installation.

[0004] However, if the above frame is simply segmented, other problems will be caused: it is not easy to form an effective seal between the filler segments, the flow path between the two adjacent filler segments is blocked or plugged, and cannot be effectively utilized; and it also has an adverse effect on the assembly work of the filler sheets.

[0087] Hereinafter, preferred embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0088]

First Embodiment

[0089] The filler module 1 of the first embodiment of the present application will be described in detail below.

[0090]

Filler module 1

[0091] In the present embodiment, the filler module 1 includes filler pieces A and filler pieces B alternately and sequentially stacked at a prescribed interval d, and the first flow path Rl and the second flow path R2 are formed in the filler module 1 by the stacked filler pieces A and B.

[0092] The upper section and the lower section of the filler module 1 form the upper section guide portion 200 and the lower section guide portion 300, respectively, and the middle section forms the heat exchange portion 400.

[0093]

Upper section guide portion 200

[0094] The upper end portion of the upper section guide portion 200 is formed by the upper end portions of the rectangular filler pieces A and B alternately arranged, and is specifically as follows.

[0095] The upper end portion of the filler piece A on the side perpendicular to the stacking direction (left side in the figure) is biased toward the side of the stacking direction (back side in the figure), and the upper end portion of the filler piece B is biased toward the opposite side (front side in the figure), so that the upper end portions of the filler pieces A-B on the left side are in contact with each other and the upper end portions of the filler pieces B-A on the left side are open to each other to form a first upper end opening 210 in the stacking direction from the front side to the back side in the figure, and a plurality of the first upper end openings 210 are arranged side by side in the stacking direction for the filler module 1. Thus, the first upper end opening 210 communicates with the first flow path Rl formed between the filler pieces B-A.

[0096] The upper end portion of the filler piece A on the other side perpendicular to the stacking direction (right side in the figure) is biased toward the other side of the stacking direction (front side in the figure), and the upper end portion of the filler piece B is biased toward the opposite side (back side in the figure), so that the upper end portions of the filler pieces B-A on the right side are in contact with each other and the upper end portions of the filler pieces A-B on the right side are open to each other to form a second upper end opening 220 in the stacking direction from the front side to the back side in the figure, and a plurality of the second upper end openings 220 are arranged side by side in the stacking direction for the filler module 1. Thus, the second upper end opening 220 communicates with the second flow path R2 formed between the filler pieces A-B.

[0097] In the upper section guide portion 200, a left upper path rectifying piece 230 is embedded in the first flow path Rl between the first upper end opening 210 formed by the filler pieces B-A and the heat exchange portion 400 surrounded by the filler pieces B-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 the upper end to the lower end, 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).

[0098] In the present embodiment, the left upper passage rectifying fin 230 has a meandering shape in a lateral cross section perpendicular to the stacking direction, and the meandering shape has its both sides in the stacking direction abut against the front surface of the packing piece A sandwiching the left upper passage rectifying fin 230 and the back surface of the packing piece B sandwiching the left upper passage rectifying fin 230. Thus, in the first flow path Rl formed between the first upper end opening 210 and the heat exchange section 400, a guide portion is formed that guides the width of the first upper end opening 210 to the full width of the heat exchange section 400.

[0099] In the upper section guide portion 200, the right upper passage rectifying fin 240 is embedded in the second flow path R2 between the second upper end opening 220 formed by the packing pieces A-B and the heat exchange section 400 surrounded by the packing pieces A-B. The right upper passage rectifying fin 240 has its upper end match the width of the second upper end opening 220, and its width gradually increases from the upper end to the lower end, and the lower end corresponds to the width of the heat exchange section 400 (the first heat exchange section 402 of the second flow path).

[0100] In the present embodiment, the right upper passage rectifying fin 240 has a meandering shape in a lateral cross section perpendicular to the stacking direction, and the meandering shape has its both sides in the stacking direction abut against the front surface of the packing piece B sandwiching the right upper passage rectifying fin 240 and the back surface of the packing piece A sandwiching the right upper passage rectifying fin 240. Thus, in the second flow path R2 formed between the second upper end opening 220 and the heat exchange section 400, a guide portion is formed that guides the width of the second upper end opening 220 to the full width of the heat exchange section 400.

[0101]

Lower section guide portion 300

[0102] In the lower section guide portion 300, the guide openings are formed by the lower end portions of the packing pieces A and B arranged alternately, and the arrangement is as follows.

[0103] In the side (left side in the drawing) perpendicular to the stacking direction, the lower end portion of the packing piece A is biased to the side (back side in the drawing) of the stacking direction, and the lower end portion of the packing piece B is biased to the opposite side (front side in the drawing) of the stacking direction. Thus, in the stacking direction from the front side to the back side in the drawing, the lower end portions of the packing pieces A and B on the left side are in contact with each other, and the lower end portions of the packing pieces B and A on the left side are open to each other to form a first lower end opening 310. Thus, the first lower end opening 310 communicates with the first flow path Rl formed between the packing pieces B and A.

[0104] The lower end portion of the filler sheet A on the side perpendicular to the stacking direction (the right side in the drawing) is offset to the other side of the stacking direction (the front side in the drawing), and the lower end portion of the filler sheet B is offset to the opposite side (the rear side in the drawing), thereby forming the second lower end opening 320 in the stacking direction from the front side to the rear side in the drawing, in which the lower end portions of the filler sheets B-A on the left side are in contact with each other, and the lower end portions of the filler sheets A-B on the left side are open to each other. Thus, the first lower end opening 320 communicates with the first flow path R2 formed between the filler sheets A-B.

[0105] In the lower section guide portion 300, the lower left flow rectifying sheet 330 is embedded in the first flow path R1 between the first lower end opening 310 formed by the filler sheets B-A and the heat exchange portion 400 surrounded by the filler sheets B-A. The lower end of the lower left flow rectifying sheet 330 matches the width of the first lower end opening 310, and the width gradually increases from the lower end to the upper end, which corresponds to the width of the heat exchange portion 400.

[0106] In the present embodiment, the lower left flow rectifying sheet 330 has a meandering shape in the lateral cross section perpendicular to the stacking direction, and the meandering back side is in contact with the front surface of the filler sheet A, and the front side is in contact with the rear surface of the filler sheet B. Thus, in the first flow path R1 formed between the first lower end opening 310 and the heat exchange portion 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 portion 400, which is approximately the width of the filler sheets A and B.

[0107] In the lower section guide portion 300, the lower right flow rectifying sheet 340 is embedded in the second flow path R2 between the second lower end opening 320 formed by the filler sheets A-B and the heat exchange portion 400 surrounded by the filler sheets A-B. The lower end of the lower right flow rectifying sheet 340 matches the width of the second lower end opening 320, and the width gradually increases from the upper end to the lower end, which corresponds to the width of the heat exchange portion 400.

[0108] In the present embodiment, the lower right flow rectifying sheet 340 has a meandering shape in the lateral cross section perpendicular to the stacking direction, and the meandering back side is in contact with the front surface of the filler sheet B, and the front side is in contact with the rear surface of the filler sheet A. Thus, in the second flow path R2 formed between the second lower end opening 320 and the heat exchange portion 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 portion 400, which is approximately the width of the filler sheets A and B.

[0109] By alternately stacking the filler sheet A and the filler sheet B to form the filler module 1, the first flow path R1 and the second flow path R2, which are isolated from each other and are alternately stacked, are formed in the filler module 1. Hereinafter, the configuration of the first flow path R1 and the second flow path R2 will be described in detail.

[0110]

Unit of the first flow path R1

[0111] In the present embodiment, for the filler module 1, in the stacking direction from the front side to the rear side in the figure, a unit of the first flow path R1 is formed between the adjacent filler sheet B and the filler sheet A located at the rear side of the filler sheet B, i.e., the filler sheet B-A.

[0112] As shown in the figure, the first flow path R1 includes, from top to bottom, the first upper end opening 210 located at the left side of the upper end of the filler module 1; the left upper segment guide portion 201 of the upper segment guide portion 200 filled and supported between the filler sheets B and A by the left upper path rectification sheet 230; the first heat exchange portion 401 in the form of a flat cavity formed between the filler sheets B-A at the heat exchange portion 400 in the stacking direction; the left lower segment guide portion 301 of the lower segment guide portion 300 filled and supported between the filler sheets B and A by the left lower path rectification sheet 330; and the first lower end opening 310 located at the left side of the lower end of the filler module 1.

[0113] Thus, in the present embodiment, a unit of the first flow path R1 in the form of a flat cavity is formed between the adjacent filler sheet B and the filler sheet A, and the first upper end opening 210 as the upper end opening thereof and the first lower end opening 310 as the lower end opening thereof are located at the same side perpendicular to the stacking direction.

[0114]

Unit of the second flow path R2

[0115] In the present embodiment, for the filler module 1, in the stacking direction from the front side to the rear side in the figure, a unit of the second flow path R2 is formed between the adjacent filler sheet A and the filler sheet B located at the rear side of the filler sheet A, i.e., the filler sheet A-B.

[0116] As shown in the figure, the second flow path R2 includes, from top to bottom, the second upper end opening 220 located at the right side of the upper end of the filler module 1; the right upper segment guide portion 202 of the upper segment guide portion 200 filled and supported between the filler sheets A and B by the right upper path rectification sheet 240; the second heat exchange portion 402 in the form of a flat cavity formed between the filler sheets A-B at the heat exchange portion 400 in the stacking direction; the right lower segment guide portion 302 of the lower segment guide portion 300 filled and supported between the filler sheets A and B by the right lower path rectification sheet 340; and the second lower end opening 320 located at the right side of the lower end of the filler module 1.

[0117] Thus, in the present embodiment, a unit of the first flow path R1 in the form of a flat cavity is formed between the adjacent filler sheet A and the filler sheet B, and the second upper end opening 220 as the upper end opening thereof and the second lower end opening 320 as the lower end opening thereof are located at the same side perpendicular to the stacking direction.

[0118]

Heat exchange portion 400

[0119] The first heat exchange portion 401 and the second heat exchange portion 402 are alternately stacked, and the heat exchange portion 400 in which the first flow path Rl and the second flow path R2 are alternately stacked to exchange heat at intervals is formed.

[0120]

Flow path upper and lower end openings

[0121] As described above, in the stacking direction of the filler pieces A, B, the first flow path Rl and the second flow path R2 in which flat cavities are formed between the filler piece B-A and the filler piece A-B, respectively, are alternately stacked. Thus, for the filler module 1, the first and second upper end openings 210, 220 which are juxtaposed in the direction perpendicular to the stacking direction are formed at the upper end edge.

[0122] In the present embodiment, as shown in the drawing, the first upper end opening 210 is formed on the left side, and since the left upper end portion of the filler piece A is biased toward the back side in the drawing and the left upper end portion of the filler piece B is biased toward the front side in the drawing, the left upper end portions of the filler piece A-B are in contact with each other, and the left upper end portions of the filler piece B-A are open to each other. Thus, the strip-shaped openings in which the left upper end portions of the filler piece B-A are open to each other are juxtaposed in the stacking direction via the left upper end portions of the filler piece A-B which are in contact with each other, and the complete first upper end opening 210 is formed. In the case where the thickness of the filler piece is not considered, the entire region on the left side in the drawing which is one side of the upper end of the filler module 1 in the direction perpendicular to the stacking direction forms the open first upper end opening 210.

[0123] Similarly, the second upper end opening 220 is formed on the right side, and, in contrast to the first upper end opening 210, the right upper end portion of the filler piece B is biased toward the back side in the drawing and the right upper end portion of the filler piece A is biased toward the front side in the drawing, so that the right upper end portions of the filler piece B-A are in contact with each other and the right upper end portions of the filler piece A-B are open to each other. Thus, the strip-shaped openings in which the right upper end portions of the filler piece A-B are open to each other are juxtaposed in the stacking direction via the right upper end portions of the filler piece B-A which are in contact with each other, and the complete second upper end opening 220 is formed. In the case where the thickness of the filler piece is not considered, the entire region on the right side in the drawing which is the other side of the upper end of the filler module 1 in the direction perpendicular to the stacking direction forms the open second upper end opening 220.

[0124] On the other hand, the first and second upper end openings 210, 220 which are juxtaposed in the direction perpendicular to the stacking direction are formed at the lower end edge.

[0125] In the present embodiment, as shown in the figure, the first lower end opening 310 is formed on the left side, and since the left lower end portions of the filler pieces A are biased toward the back side in the figure and the left lower end portions of the filler pieces B are biased toward the opposite front side in the figure, the left lower end portions of the filler pieces A-B are in contact with each other, and the left lower end portions of the filler pieces B-A are open to each other. Thus, the strip-shaped openings in which the left lower end portions of the filler pieces B-A are open to each other are arranged side by side in the stacking direction via the left lower end portions of the filler pieces A-B that are in contact with each other, and the complete first lower end opening 310 is formed. In the case where the thickness of the filler pieces is not considered, the entire area on the side (left side in the figure) of the lower end of the filler module 1 that is perpendicular to the stacking direction forms the open first lower end opening 310.

[0126] Similarly, the second lower end opening 320 is formed on the right side, and, in contrast to the first lower end opening 310, the right lower end portions of the filler pieces B are biased toward the back side in the figure and the right lower end portions of the filler pieces A are biased toward the opposite front side in the figure, so that the right lower end portions of the filler pieces B-A are in contact with each other and the right lower end portions of the filler pieces A-B are open to each other. Thus, the strip-shaped openings in which the right lower end portions of the filler pieces A-B are open to each other are arranged side by side in the stacking direction via the right lower end portions of the filler pieces B-A that are in contact with each other, and the complete second lower end opening 320 is formed. In the case where the thickness of the filler pieces is not considered, the entire area on the other side (right side in the figure) of the lower end of the filler module 1 that is perpendicular to the stacking direction forms the open second lower end opening 320.

[0127]

Opening of flow path

[0128] The first flow path Rl will be described in further detail in the direction from the top to the bottom.

[0129] As described above, the first flow path Rl at the upper end of the filler module 1 forms the first upper end opening 210 on the entire area on the left side that is perpendicular to the stacking direction, and at the first upper end opening 210, the portions in which the left upper end portions of the filler pieces A-B are in contact with each other are divided into a plurality of units. In the left upper segment guide portion 201, after passing through the portions in which the left upper end portions of the filler pieces A-B are in contact with each other downward, the units of the first flow path Rl are separated from each other in the stacking direction, and on one hand, the size in the stacking direction gradually decreases, and on the other hand, the size perpendicular to the stacking direction gradually increases to substantially the width of the filler pieces 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 portion 401 of the flat heat exchange space defined by the filler pieces B-A that enter the heat exchange portion 400 from the upper segment guide portion 200.

[0130] In the case of continuing downward from the heat exchange section 400 to the lower section guide section 300, contrary to the case in the upper section guide section 200, the unit of the first flow path Rl is flattened by the width of the packing pieces A, B downward, and on the one hand, the dimension in the stacking direction gradually becomes larger, and on the other hand, the dimension in the direction perpendicular to the stacking direction gradually becomes smaller to the width of the second lower end opening 220, that is, the thickness becomes larger and the width becomes smaller, and in the left lower section guide section 301, it is converged from the portion where the left side lower end portions of the packing pieces A-B adhere to each other to reach the first lower end opening 310.

[0131] Thus, in the first flow path Rl, the entire section flow path from the first upper end opening 210 through the upper section guide section 200, the heat exchange section 400, the lower section guide section 300 to the first lower end opening 310, the cross-sectional area of which is theoretically substantially constant.

[0132] For the second flow path R2, which is rotationally symmetrical to the first flow path Rl, further detailed description is given below.

[0133] As described above, the second flow path R2 at the upper end of the packing module 1, a second upper end opening 210 is formed in the entire area on the right side perpendicular to the stacking direction, and at the second upper end opening 210, the portion where the right side upper end portions of the packing pieces B-A adhere to each other is divided into a plurality of units. In the right upper section guide section 202, after passing through the portion where the right side upper end portions of the packing pieces B-A adhere to each other downward, the units of the first flow path Rl are separated from each other in the stacking direction, and on the one hand, the dimension in the stacking direction gradually becomes smaller, and on the other hand, the dimension in the direction perpendicular to the stacking direction gradually becomes larger to the width of the packing pieces A, B to form a flattened shape, that is, the thickness becomes smaller and the width becomes larger, and the units of the second heat exchange section 402 of the flattened heat exchange space defined by the packing pieces A-B from the upper section guide section 200 into the heat exchange section 400.

[0134] In the case of continuing downward from the heat exchange section 400 to the lower section guide section 300, contrary to the case in the upper section guide section 200, the unit of the first flow path Rl is flattened by the width of the packing pieces A, B downward, and on the one hand, the dimension in the stacking direction gradually becomes larger, and on the other hand, the dimension in the direction perpendicular to the stacking direction gradually becomes smaller to the width of the second lower end opening 220, that is, the thickness becomes larger and the width becomes smaller, and in the left lower section guide section 301, it is converged from the portion where the left side lower end portions of the packing pieces A-B adhere to each other to reach the first lower end opening 310.

[0135] Thus, in the second flow path R2, the entire section flow path from the second upper end opening 220 through the upper section guide section 200, the heat exchange section 400, the lower section guide section 300 to the second lower end opening 320, the cross-sectional area of which is theoretically substantially constant.

[0136] As described above, in the present embodiment, the first and second upper end openings 210, 220, which are the upper end openings of the first and second flow paths Rl, R2, have a total of the opening areas that is identical to a total of the cross-sectional areas of the flow paths from the upper portion to the lower portion. Similarly, the first and second lower end openings 310, 320, which are the lower end openings of the first and second flow paths Rl, R2, have a total of the opening areas that is identical to a total of the cross-sectional areas of the flow paths from the upper portion to the lower portion, that is, the opening areas of the upper end and the lower end of the packing module 1 are identical to the cross-sectional areas in the horizontal direction of the packing module 1, so that the flow rate and the passing efficiency of each flow path Rl, R2 can be greatly improved, and the resistance of the packing module 1 can be reduced, which will be described in further detail later.

[0137]

Rectifier piece

[0138] Thus, when the rectifier pieces 230, 240, 330, 340 are inserted in each of the guide portions 201, 202, 301, 302, that is, the rectifier pieces 230, 240, 330, 340 are inserted into each of the first and second flow paths Rl, R2, since each of the rectifier pieces 230, 240, 330, 340 is formed in a curved shape, and the extension direction of the curved protrusions is respectively corresponding to the extension path of the first and second flow paths Rl, R2, and the thickness of each of the rectifier pieces 230, 240, 330, 340 is greatly different from the cross-sectional area of the first and second flow paths Rl, R2, so that the passing efficiency of the first and second flow paths Rl, R2 will not be affected.

[0139] 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 Rl, R2, are arranged in parallel in the direction perpendicular to the stacking direction, and have substantially the same width, so that the left upper rectifier piece 230 and the right upper rectifier piece 240, which are respectively located in the left upper guide portion 201 and the right upper guide portion 202, have substantially the same configuration of the accommodation space, and are arranged in a rotational symmetry manner, so that the same components can be used to configure the left upper rectifier piece 230 and the right upper rectifier piece 240.

[0140] Similarly, the first lower end opening 310 and the second lower end opening 320, which are the lower end openings of the first and second flow paths Rl, R2, are arranged in parallel in the direction perpendicular to the stacking direction, and have substantially the same width, so that the left lower rectifier piece 330 and the right lower rectifier piece 340, which are respectively located in the left lower guide portion 301 and the right lower guide portion 302, have substantially the same configuration of the accommodation space, and are arranged in a rotational symmetry manner, so that the same components can be used to configure the left lower rectifier piece 330 and the right lower rectifier piece 340.

[0141] Further, in the present embodiment, by making the heights of the upper section guide portion 200 and the lower section guide portion 300 substantially the same, the constitution of the accommodation spaces of the respective rectifier fins 230, 240, 330, 340 is made substantially the same, so that the same components can be used to constitute the left upper path rectifier fin 230, the right upper path rectifier fin 240, the left lower path rectifier fin 330, and the right lower path rectifier fin 340. Thus, when the filler module 1 is manufactured, only the filler sheet A, the filler sheet B, and the common rectifier fin are needed, so that the production cost of the filler module 1 is significantly reduced, and the assembly efficiency is significantly improved.

[0142] In the present embodiment, the same filler sheet A and the filler sheet B as in the first embodiment can be used. In the first embodiment, the left upper path rectifier fin 230, the right upper path rectifier fin 240, the left lower path rectifier fin 330, and the right lower path rectifier fin 340 are respectively provided for the left upper section guide portion 201, the right upper section guide portion 202, the left lower section guide portion 301, and the right lower section guide portion 302. However, the left upper section guide portion 201 and the left lower section guide portion 301 are both located on the same side of the filler module 1 (the left side in the first embodiment), and the right upper section guide portion 202 and the right lower section guide portion 302 are both located on the other same side of the filler module 1 (the right side in the first embodiment), that is, the fluid flowing into / introduced into the filler module 1 from one side (the left side) in the width direction of the filler module 1 forms a flow path R1 of substantially full width of the filler module 1 in the heat exchange portion 400, and the fluid flowing into / introduced into the filler module 1 from the other side (the right side) in the width direction of the filler module 1 forms a flow path R2 of substantially full width of the filler module 1 in the heat exchange portion 400, the thicknesses of R1 and R2 in the stacking direction are half of the thicknesses of the respective openings in the stacking direction, and the sum of the respective thicknesses of R1 and R2 is equivalent to half of the thickness of the filler module 1 in the stacking direction. Thus, a same-side inflow and outflow state is formed, that is, if hot water flows into the first upper end opening 210 at the left upper end, the filler module 1 is outflowed from the first lower end opening 310 at the left lower end, and if cold air is introduced into the first lower end opening 310 at the left lower end, the filler module 1 is outflowed from the first upper end opening 210 at the left upper end, becoming the first flow path R1; the same is true for the second upper end opening 220 and the second lower end opening 320 as the upper and lower end openings on the right side, except that the fluid flowing through is different from that on the left side, becoming the second flow path R2. Of course, the filler module 1 can also be such that, as with the conventional filler module, the first and second upper end openings 210, 220 simultaneously pour in hot water, and the first and second lower end openings 310, 320 simultaneously attract cold air, forming the hot water and the cold air in the flow paths to directly contact each other in reverse directions to exchange heat, except that, when the first and second flow paths R1, R2 respectively flow in different fluids, the outflowed hot air after heat exchange has a low saturation humidity, avoiding fogging.

[0143] 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.

[0144] [Second Implementation Method]

[0145] The packing module 1', a preferred embodiment of the present invention, differs from the packing module 1 of the first embodiment in that rectifiers are only provided in the first flow path R1, specifically the upper left rectifier 230 and the lower left rectifier 330 located in the upper left guide section 201 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.

[0146] 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'.

[0147] 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'.

[0148] As can be seen, compared with the packing module 1 of the first embodiment of the present invention, 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.

[0149] 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.

[0150] 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. AThe left end edge of the filler sheet A is formed with a left edge portion 215A offset by a distance d / 2 from the front side of the rear half of the first upper end opening 210. The left edge portion 215A extends linearly in the up-down direction. A The left end edge of the filler sheet A is formed with a left edge portion 215A offset by a distance d / 2 from the front side of the rear half of the first upper end opening 210. The left edge portion 215A extends linearly in the up-down direction.

[0151] Further, at the upper end portion of the filler sheet A, on the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the second upper end opening 220 side, a front half of the second upper end opening 210 of the second flow path R2 on the front side is formed by the filler sheet A, offset by a distance d / 2 from the front side.

[0152] Further, at the upper end portion of the filler sheet A, on the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the second upper end opening 220 side, a front half of the second upper end opening 210 of the second flow path R2 on the front side is formed by the filler sheet A, offset by a distance d / 2 from the front side. B The left end edge of the filler sheet A is formed with a left edge portion 215A offset by a distance d / 2 from the front side of the rear half of the first upper end opening 210. The left edge portion 215A extends linearly in the up-down direction. B The left end edge of the filler sheet A is formed with a left edge portion 215A offset by a distance d / 2 from the front side of the rear half of the first upper end opening 210. The left edge portion 215A extends linearly in the up-down direction.

[0153] Further, at the upper end portion of the filler sheet A, on the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the second upper end opening 220 side, a front half of the second upper end opening 210 of the second flow path R2 on the front side is formed by the filler sheet A, offset by a distance d / 2 from the front side.

[0154] Further, at the upper end portion of the filler sheet A, on the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the second upper end opening 220 side, a front half of the second upper end opening 210 of the second flow path R2 on the front side is formed by the filler sheet A, offset by a distance d / 2 from the front side.

[0155] Thus, for the first flow path Rl formed by the filler sheet A and the filler sheet B adjacent to the front side thereof, it has a flow inlet of 2d thickness, i.e., the first upper end opening 210, and the left seal edge 215 is formed by combining the left seal edge portion 215A and the left seal edge portion 215B offset to each other and converged. The left seal edge 215 can easily form a sealing structure when performing a joint seal. When the first flow path Rl is used as a flow path for hot water shower, since the hot water is showered from the first upper end opening 210 arranged in front and back on the left side of the filler module 1', the hot water is not easily seeped from the left seal edge 215 when the hot water is guided into the heat exchange portion 400.

[0156] On the other hand, after the hot water is guided from the first upper end opening 210 to the heat exchange portion 400, the water is spread in the heat exchange portion 400 along the rear wall surface of the filler sheet B and the front wall surface of the filler sheet A under the action of its own gravity, and does not easily intrude into the right seal edge of the filler module 1'. Thus, the sealing requirement for the right seal edge is significantly reduced.

[0157] Specifically, in the present embodiment, for the lower section guide portion 300, if the lower section guide portion 300 is rotated 180° with the horizontal axis perpendicular to the stacking direction as the center, its structure is the same as that of the upper section guide portion 200. For the lower section guide portion 300, as with the structure of the upper section guide portion 200, the lower end edges of the filler sheet A and the filler sheet B adjacent to the front side thereof are arranged offset, so that from the upper to the lower of the left side edges of the filler sheet A and the filler sheet B, and including the left side edge of the heat exchange portion 400, the continuous left seal edge portions 215A, 215B are formed, so that water seepage from the left seal edge 215 can be effectively avoided, especially the water seepage from the left seal edge 215 at the portions of the upper section guide portion 200 and the lower section guide portion 300.

[0158] Further, in the present embodiment, for the seal edge portion 215 formed by the left seal edge portions 215A, 215B, any joint method can be used, and from the perspective of assembly convenience, it is preferred that the seal edge portion 210 is jointed by pressure welding. This is because, when the filler sheets A, B and the rectifier sheets 230, 330 are assembled using equipment, by aligning the filler sheet B and the filler sheet B adjacent in the front-rear direction, since the filler sheets A, B are offset to each other at the right side portions of the upper and lower end edges, the filler sheets B-A can be welded by operating the pressure welding equipment to weld the seal edge portion 215 and the right side portions of the upper and lower end edges of the filler sheets B-A in this state.

[0159] 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.

[0160] 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.

[0161] [Third Implementation Method]

[0162] As a preferred embodiment of the present invention, the third embodiment of the filling module 1”, such as Figure 13 , 14 As shown, the difference from the packing module 1 of the first embodiment is the configuration and assembly method of the upper left rectifier 230, 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.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] In the process of stacking the filler sheets A, B, at the left upper section guide portion 201, since the filler sheet A is biased to the rear side in the stacking direction, and the filler sheet B is biased to the front side in the stacking direction, the left upper end edges of both are converged at the edge of the first upper end opening 210.

[0167] Since the rectifier sheet 230 embedded in the left upper section guide portion 201 is located inside the first upper end opening 210, it avoids the upper end edges of the filler sheets A-B at the first upper end opening 210 in the stacking direction, and maintains a distance of h. Thus, the avoidance area can be subjected to the welding process by the heating clamp, thereby forming a welding track L.

[0168] In the first and second embodiments, the rectifier sheet 230 is not retracted into the first upper end opening 210, and when the welding process is performed, only the bending of the rectifier sheet 230 can be adapted due to the interference of the rectifier sheet arranged in the bending at the end surface of the first upper end opening 210, forming an intermittent weld. As for the left upper end edges of the filler sheets A-B, only the sealing by gluing can be achieved after convergence.

[0169] Unlike this, in the present embodiment, by retracting the rectifier sheet into the first upper end opening 210, the left upper end edges of the filler sheets A-B can be subjected to continuous pressure welding welding using the avoidance area.

[0170] In this way, on the one hand, the connection strength of the left upper end edges of the filler sheets A-B is improved, so that after the multi-layer stacking of the filler sheets A, B, the overall strength of the filler module 1" can also be significantly improved.

[0171] On the other hand, more importantly, in the case where the left first flow path R1 is used as a hot water spray flow path, and the right second flow path R2 is used as an air flow path, the inside of the left upper end joint of the filler sheets A-B forming the first upper end opening 210 is in communication with the second flow path R2. By adopting welding joint for the joint, the water tightness can be effectively improved, and the situation of water leakage due to aging and peeling off can be avoided.

[0172] Furthermore, in the present embodiment, by locating the first lower end opening on the left side of the filler module 1" as shown in the second embodiment, and forming continuous edge sealing portions 215A, 215B on the left edges of the filler sheet A and the filler sheet B respectively, the probability of the first flow path R1 leaking to the second flow path when used as a hot water spray flow path can be minimized; the left side can also be sealed by welding and will not leak.

[0173] For the right side, the hot water is guided by the first flow path R1 from a portion of the width of the left side to substantially the full width of the heat exchange portion, and then back to a portion of the width of the left side to flow out from the first lower end opening 310. Therefore, under the action of gravity, the hot water is difficult to overflow from the right edge, and thus the right edge can be embedded and connected, bonded, spot-welded, etc. in a simple convex-concave joint manner.

[0174] Of course, without considering the slight increase in cost, the right edge can also be processed in the same manner as the left edge. Of course, the right edge can also be formed by biasing the right edge of the heat exchange portion 400 of the filler sheet A and B to the same direction as the left edge. Thus, the first flow path can be completely closed.

[0175] In this embodiment, as an example, only the configuration of the left upper rectifier sheet 230 in the left upper section guide portion 201 and the first upper end opening 210 is described. The same configuration can also be used for the other second upper end opening 220, the first lower end opening 310, the second lower end opening 320, and the corresponding rectifier sheets 240, 330, and 340. Thus, the strength of the entire filler module 1" can be improved, and in particular, the strength of the upper and lower end surfaces of the filler module 1" having the upper and lower end openings 210, 220, 310, 320 arranged side by side can be greatly improved. In this way, the firmness, reliability, and durability of the filler module 1" during transportation, operation, installation, and daily operation can be greatly improved.

[0176] [Fourth Embodiment]

[0177] In the first embodiment, the first upper end opening 210 and the first lower end opening 310 can be located on the left side of the filler module and have the same width, and the second upper end opening 220 and the second lower end opening 320 can be located on the right side of the filler module and have the same width, i.e., the same side and the same width. Thus, the filler sheet A and the filler sheet B can have the same components, reducing the manufacturing cost of the filler module. That is, the filler sheet B (i.e., the filler sheet A after being flipped) can be in a state of being flipped 180° relative to the horizontal axis with respect to the filler sheet A. Therefore, in this embodiment, the description of the filler sheet B is based on the position of the filler sheet A before being flipped.

[0178] The filler sheet A is configured to have a left upper biasing portion biased to the rear side on the left side of the upper end portion, a right upper biasing portion biased to the front side on the right side of the upper end portion, a left lower biasing portion biased to the rear side on the left side of the lower end portion, and a right lower biasing portion biased to the front side on the right side of the lower end portion. The adjacent filler sheet B can be arranged in a manner of being flipped 180° around the horizontal axis of the body portion of the filler sheet A.

[0179] Thus, the right upper offset portion of the filler sheet A is aligned with the right lower offset portion of the filler sheet B located on the front side in the stacking direction, and the right lower offset portion of the filler sheet A is aligned with the right upper offset portion of the filler sheet B, thereby forming a first upper end opening 210 between the left upper offset portion of the filler sheet A and the left lower offset portion of the filler sheet B, and a first lower end opening 310 between the left lower offset portion of the filler sheet A and the left upper offset portion of the filler sheet B, and the first upper end opening 210 and the first lower end opening 310 are respectively communicated with a first heat exchange portion 401 formed between the body portion of the filler sheet A and the body portion of the filler sheet B in the up-and-down direction, thereby forming a first flow path Rl.

[0180] The left upper offset portion of the filler sheet A is aligned with the left lower offset portion of the filler sheet B located on the rear side in the stacking direction, and the left lower offset portion of the filler sheet A is aligned with the left upper offset portion of the filler sheet B, thereby forming a second upper end opening 220 between the right upper offset portion of the filler sheet A and the right lower offset portion of the filler sheet B, and a second lower end opening 320 between the right lower offset portion of the filler sheet A and the right upper offset portion of the filler sheet B, and the second upper end opening 220 and the second lower end opening 320 are respectively communicated with a second heat exchange portion 402 formed between the body portion of the filler sheet A and the body portion of the filler sheet B in the up-and-down direction, thereby forming a second flow path R2.

[0181] Further, a left upper rectifying sheet 230 is provided between the left upper offset portion of the filler sheet A and the left lower offset portion of the filler sheet B, which gradually increases in width and gradually decreases in thickness from the first upper end opening 310 to the first heat exchange portion 401.

[0182] A left lower rectifying sheet 330 is provided between the left lower offset portion of the filler sheet A and the left upper offset portion of the filler sheet B, which gradually increases in width and gradually decreases in thickness from the first lower end opening 310 to the first heat exchange portion 401.

[0183] Similarly, a right upper rectifying sheet 240 is provided between the right upper offset portion of the filler sheet A and the right lower offset portion of the filler sheet B, which gradually increases in width and gradually decreases in thickness from the second upper end opening 220 to the second heat exchange portion 402.

[0184] A right lower rectifying sheet 340 is provided between the right lower offset portion of the filler sheet A and the right upper offset portion of the filler sheet B, which gradually increases in width and gradually decreases in thickness from the second lower end opening 320 to the second heat exchange portion 402.

[0185] On this basis, if the left side edge of each filler sheet A is offset to the front side to form a straight edge portion 215A as in the second embodiment, the edge portion of the filler sheet A is aligned with the edge portion 215B of the filler sheet B located on the front side in the stacking direction.

[0186] The edge portion 215A of the filler sheet A is butted against the edge portion 215B of the filler sheet B located on the front side in the stacking direction, and is welded and joined to form a left edge 215.

[0187] Thus, according to the present embodiment, the number of components can be further reduced, and when the filler module is assembled using the filler sheets, it is only necessary to sequentially stack the filler sheet A which is not turned over and the filler sheet B which is turned over by 180°.

[0188]

Cooling tower 1

[0189] Figure 10 is a schematic view of a cooling tower made based on the filler module 1 of the present embodiment.

[0190] The bottom layer of the cooling tower 10 is an air inlet layer 101, and a plurality of air doors 102 are arranged on the periphery of the air inlet layer 101. A filler layer 103 is arranged above the air inlet layer 101, and the filler layer 103 is arranged in a matrix shape in the horizontal plane by a plurality of filler modules 1. A spraying portion 104 is arranged above the filler layer 103, and the spraying portion 104 sprays hot water to be treated to each filler module 1 of the filler layer 103. A partition plate 105 extending in the stacking direction of the filler module 1 is arranged substantially vertically in the region between the spraying portion 104 and the filler layer 103, and a plurality of interval spaces 105a, 105b are formed by the partition plate 105 and the top surface of the filler module 1, wherein the interval space 105a serves as a spraying space for spraying hot water, and the interval space 105b serves as a gas suction space for suctioning gas from the bottom to the top. The spraying space 105a and the gas suction space 105b are arranged alternately in the direction perpendicular to the stacking direction of the matrix formed by the filler modules 1, and each partition plate 105 is arranged at the intersection position of the first upper end opening 210 and the second upper end opening 220 of the filler module 1, so as to separate the first flow path R1 and the second flow path R2 which communicate with the first upper end opening 210 and the second upper end opening 220.

[0191] An air outlet 108 provided with a fan 107 is arranged above the air outlet layer 106, and the fan 107 sucks air upward, so that cool air enters the air inlet layer 101 from the air door 102 of the lower layer of the cooling tower 10, passes through each filler module 1 of the filler layer 103 upward, respectively passes through the spraying space 105a and the gas suction space 105b, and is further mixed in the air outlet layer 106, and is then discharged upward through the air outlet 108.

[0192] On the other hand, the hot water to be treated sprayed from the spraying portion 104 to each filler module 1 of the filler layer 103 is cooled by each filler module 1, and then falls to the bottom surface of the air inlet layer 101, and the cooled water is collected by a collection device for recycling in the factory.

[0193] Working state one:

[0194] As described above, the cooling tower 10 is set to the winter operation state. At this time, the hot water to be treated sprayed from the spray part 104 is restricted in the spray space 105a to enter one of the two flow paths of the filler module 1. In the present embodiment, since the partition plate 105 is arranged at the junction of the first upper end opening 210 and the second upper end opening 220 with respect to the filler module 1, the first and second flow paths Rl, R2 adjacent to each other between the two adjacent filler modules 1 are formed as water flow paths, and the outer flow paths Rl, R2 are adjacent to the second and first flow paths on both sides, respectively, and are formed as air flow paths.

[0195] In the water flow paths, the sprayed water flows into the filler module 1, passes through the upper section guide part 200, and is formed in the heat exchange part 400 as a water film distributed to both side walls in the stacked direction in a flat space of substantially full width of the filler module 1. The flow paths adjacent to each other in the stacked direction are formed as air flow paths, and the walls of the filler sheets A, B therebetween perform heat exchange with the hot water in the water flow paths.

[0196] When the cooling tower 10 operates in winter, the air sucked into the air flow paths from below the filler module 1 is dry cold air, which has a low temperature and a low water content. When the air in the air flow paths of the filler module 1 performs heat exchange with the hot water, the heat exchange is completed in the independent flow paths completely through the filler sheets A, B, so that the temperature of the air increases when it is discharged from above the filler module 1, but the water content does not change at this time, i.e., dry hot air is formed.

[0197] On the other hand, since there is hot water sprayed from the spray part 104 above in the water flow paths, the air in the water flow paths sucked by the fan 107 has a large resistance, so that the air flow rate through the air flow paths is very small, usually only one third. The air flowing through the air flow paths forms hot saturated air, i.e., humid hot air.

[0198] The dry hot air flowing through the air flow paths and the humid hot air flowing through the water flow paths are mixed in the exhaust layer 106. Since the humid hot air is small, the unsaturated hot air is formed after the dry hot air is mixed with the humid hot air, and the unsaturated hot air is gradually cooled and the water content is small after being discharged to the atmosphere through the fan 107 and the exhaust port 108, so that the amount of fog is greatly reduced.

[0199] In the embodiment, by switching the spraying part 104, the spraying space 105a and the air induction space 105b can be switched flexibly, i.e. stopping spraying hot water to the spraying space 105a and spraying hot water to the air induction space 105b, so that the functions of the spraying space 105a and the air induction space 105b can be exchanged, on the one hand, the normal working of the cooling tower 10 can be ensured, and on the other hand, the flow path R1 or R2 of the packing module 1 communicated with the air induction space 105b can be effectively cleaned and maintained, so that the normal operation of the cooling tower 10 is not affected when the cooling tower 10 is cleaned and maintained.

[0200] Working state two:

[0201] When in the summer working state, by adjusting the spraying part 104, the air induction space 105b can be sprayed with hot water as the spraying space 105a, so that the heat exchange efficiency of the cooling tower 10 can be improved as much as possible without fogging in summer.

[0202]

Cooling tower 20

[0203] In the embodiment, the packing module 1 described above is still used, but as the cooling tower 20, only the differences from the cooling tower 10 will be described in detail, and the same structure will not be described again.

[0204] The cooling tower 20 of the embodiment is different from the cooling tower 10 described above in that for each spraying space 105a, a cover plate 109 along the stacking direction of the packing module 1 is further arranged substantially horizontally at the upper part of the partition plate 105. By arranging the cover plate 109, the partition plate 105 and the packing module 1, a plurality of interval spaces 205a, 205b are formed. In the embodiment, the cover plate 109 is arranged only in the spraying space 205a for spraying hot water, and the cover plate 109 is not arranged in the air induction space 205b for air exhaust; of course, the cover plate 109 can be arranged in both the spraying space 105a and the air induction space 205b, and the cover plate 109 can be arranged as a continuous plate or a plurality of plates combined, and the cover plate 109 can be flipped or flipped in a way that the spraying space 205a and the air induction space 205b can be switched, so that the spraying space 205a and the air induction space 205b can be switched.

[0205] Working state one:

[0206] This working state is especially suitable for winter in northern China, and in this state, the working process of the cooling tower 20 is similar to that of the cooling tower 10 described above, except that the cover plate 109 is arranged above the spraying space 205a, so that the spraying space 205a will not function as air induction in principle, and only hot water passes through the flow path R1 or R2 of the packing module corresponding to the spraying space 205a, so that only dry hot air from the air induction space 205b is present in the air exhaust layer 106 of the cooling tower 20.

[0207] Therefore, the cooling tower 20 only has dry hot air drawn from the exhaust port 108 by the fan 107, so that the moisture in the hot air discharged from the cooling tower 20 is reduced as much as possible, thereby further improving the fog dissipation capability of the cooling tower 20 in winter, and since the discharged air is only dry hot air, the amount of water discharged from the cooling tower 20 is also less, which is more conducive to water saving.

[0208] In the case where the cover plates 109 that can be opened and closed (flat opening or opposite opening or removable) are provided in both the spray space 205a and the air induction space 205b, by opening the cover plate above the spray space 205a and closing the cover plate above the air induction space 205b, and adjusting the spray part 104, the functions of the spray space 205a and the air induction space 205b can be exchanged as in the cooling tower 10 described above, and the flow path R1 or R2 of the filler module 1 corresponding to the original air induction space 205b is cleaned, thereby avoiding shutdown of the cooling tower 20.

[0209] Of course, by only opening the cover plate 109, the same working state as the cooling tower 10 described above can be achieved, and the working efficiency and working result are also approximately the same.

[0210] Working state two:

[0211] In the summer working state, by removing or opening the cover plate 109 above the spray space 205a, the spray part 104 is adjusted so that hot water is sprayed to the air induction space 205b as well as the spray space 205a, and the cooling tower 20 achieves the working state of improving heat exchange efficiency in summer as in the cooling tower 10 described above.

[0212] In the cooling tower 20 of the present embodiment, the cover plate 109 provided above the interval space 205a, 205b is a flat plate, but is not limited thereto, and can be a plate extending from the partition plate 105 on both sides of the filler module 1 in the stacking direction of the interval space 205a, 205b to the middle and lapping to close the interval space 205a, 205b, and forming a top corner upward or downward at the lapped part, that is, as long as the upper part of the interval space 205a, 205b can be closed, there is no limitation on the constituting mode of the cover plate 109.

[0213] In the above embodiment, the flow regulating piece 230 is provided in the left upper section guide part 201 formed between the filler pieces B-A of the filler module 1 in the stacking direction of the upper section flow guide part 200 of the first flow path R1.

[0214] Further, the flow regulating piece 240 is provided in the right upper section guide part 202 formed between the filler pieces A-B in the stacking direction of the upper section flow guide part 200 of the second flow path R2.

[0215] On the other hand, the rectifying fin 330 is arranged in the lower left segment guide portion 301 of the lower segment flow guide portion 300 of the first flow path R1 formed between the filler pieces B-A in the stacking direction.

[0216] Further, the rectifying fin 340 is arranged in the upper right segment guide portion 202 of the lower segment flow guide portion 300 of the second flow path R2 formed between the filler pieces A-B in the stacking direction.

[0217] Since the first upper end opening 210 and the second upper end opening 220 each occupy approximately half of the width of the filler module 1, in practice, the rectifying fin 230 is embedded in a substantially right-angled trapezoidal region formed by extending from the substantially middle portion of the upper edge of the filler piece B-A downward toward the left side edge of the upper segment guide portion 200, then rightward along the lower end portion line of the side upper segment guide portion 200 to the right side edge of the upper segment guide portion 200, and then upward toward the substantially middle portion of the upper edge of the filler piece A(B). For the filler piece A, the trapezoidal region is biased toward the rear side, and for the filler piece B, the trapezoidal region is biased toward the front side, so that in the stacking direction, the front side filler piece A and the rear side filler piece B, i.e., the filler pieces A-B, are in close contact at the periphery of the first upper end opening 210, and the front side filler piece B and the rear side filler piece A, i.e., the filler pieces B-A, are separated by a width of 2d in the stacking direction at the first upper end opening 210. That is, in the trapezoidal region, the distance in the stacking direction at the upper end of the first upper end opening 210 is substantially 2d, and the distance in the stacking direction at the lower end where the upper segment guide portion 201 is connected to the heat exchange portion 400 is the interval d between the filler pieces A and B, thereby forming the space of the upper left segment guide portion 201.

[0218] The cross section of the rectifying fin 230 in the horizontal direction is a meandering shape extending perpendicularly to the stacking direction. The meandering amplitude is large and the meandering span is small at the upper portion near the first upper end opening 210, and the meandering amplitude gradually decreases and the meandering span gradually increases as the rectifying fin 230 extends from the top downward toward the heat exchange portion 400, so as to fill the space of the upper left segment guide portion 201. By making the rectifying fin 230 meander in the horizontal direction, a plurality of guide flow paths are formed from the first upper end opening 210 to the heat exchange portion 400. Each guide flow path has a large thickness in the stacking direction and a small width in the horizontal direction at the upper end, and a small thickness and a large width at the lower end, so as to effectively guide the hot water flowing in from the first upper end opening 210, which has a width of substantially half of the width of the filler module 1, to the heat exchange portion 400, which has a width of substantially the full width of the filler module 1, and the cross-sectional area of the guide flow path changes as little as possible from the top to the bottom, so as to reduce the resistance of the fluid. Good passing efficiency is achieved for both the hot water sprayed from above and the air drawn upward from below.

[0219] The rectifying fins 240 located in the space of the right upper segment guide part 202 are also the same structure, but are arranged in a position that is rotationally symmetrical with the rectifying fins 240 in the horizontal direction.

[0220] For the rectifying fins 330, 340, like the upper segment guide part 200, the left upper segment guide part 201 and the right upper segment guide part 202, the rectifying fins 330, 340 are respectively arranged in the left lower segment guide part 301 formed by offsetting the area of the inverted right-angled trapezoidal region of the filler piece B-A at the lower segment guide part 300 to the outside of the stacking direction, and the right lower segment guide part 302 formed by offsetting the area of the inverted right-angled trapezoidal region of the filler piece A-B at the lower segment guide part 300 to the outside of the stacking direction. The rectifying fins 330, 340 respectively form a plurality of flow paths in the left lower segment guide part 301 and the right lower segment guide part 302, the upper end of which has a small thickness in the stacking direction and a large width in the horizontal direction, and the lower end of which has a large thickness and a small width, so as to guide the water from the first and second flow paths R1, R2 of the heat exchange part 400 of the filler module 1 to the first and second lower end openings 310, 320 of approximately half the width.

[0221] That is, for the rectifying fins 330, 340, the bending amplitude is large and the bending span is small at the first and second lower end openings 310, 320, and gradually decreases and gradually increases, respectively, during the extension from the bottom to the top towards the heat exchange part 400.

[0222] For the rectifying fins 330 located in the space of the left lower segment guide part 301 and the rectifying fins 340 located in the space of the right lower segment guide part 302, they are also rotationally symmetrical in the horizontal direction.

[0223] Therefore, in the case that the first and second upper end openings 210, 220 and the first and second lower end openings 310, 320 are all approximately half the width of the filler module 1, if the vertical direction lengths of the upper and lower segment guide parts 200, 300 are the same, the left upper segment guide part 201, the right upper segment guide part 202, the left lower segment guide part 301 and the right lower segment guide part 302 can form a rotationally symmetrical structure, and thus the rectifying fins 230, 240, 330 and 340 can be the same components, so that the filler module 1 only needs three types of components, i.e. the filler piece A, the filler piece B and the universal rectifying fin, during production, which not only significantly reduces the mold cost and the component production cost for producing the filler module 1, but also makes the assembly convenient without considering the model difference of the rectifying fins, thereby greatly reducing the overall production cost of the filler module 1.

[0224] According to the above-described preferred embodiment, by offsetting and fitting the filler sheet A and the filler sheet B in the upper section guide portion and the lower section 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 provided in the stacking direction, and the total size of the openings in the stacking direction is substantially the same as the stacking thickness of the filler module in the stacking direction, without considering the thickness of the filler sheet A and B.

[0225] [5th Embodiment]

[0226] In the filler module 1000 of the present embodiment, as in each of the above-described embodiments, a configuration having a plurality of filler sheets alternately stacked is adopted, and a first flow path and a second flow path are respectively formed between the plurality of filler sheets 1000A and 1000B. That is, as shown in FIG. 10, in the filler module 1000, the first flow path 1000G is formed between the filler sheets 1000A-1000B in the front-to-back direction in the stacking direction of the filler module, and the second flow path 1000W is formed between the filler sheets 1000B-1000A. Figure 17

[0227] The difference from each of the above-described embodiments is the position at which the upper end openings of the first flow path 1000G and the second flow path 1000W are provided. In the present embodiment, in the upper end left-right direction of the filler module 1000, the upper end opening G of the first flow path 1000G as the first upper end opening is provided at the middle portion, and the upper end openings W of the second flow path 1000W as the second upper end opening include an upper end opening W1 provided on the left side of the upper end opening G and an upper end opening W2 provided on the right side of the upper end opening G. That is, in the present embodiment, the second flow path 1000W has two upper end openings W, and is provided in a manner sandwiching the upper end opening G of the first flow path 1000G.

[0228] In the present embodiment, the upper end opening G of the first flow path 1000G communicates with the first heat exchange portion 401 of the first flow path 1000G via the upper section guide portion of the first flow path 1000G, and guides the upper end opening G, which occupies the middle portion in the upper end width direction of the filler module 1000, to the first heat exchange portion 401, which occupies substantially the entire width of the filler module 1000.

[0229] The two upper end openings W1 and W2 of the second flow path 1000W communicate with the second heat exchange portion 402 of the second flow path 1000W via the upper section guide portion of the second flow path 1000W, and guide the upper end openings W1 and W2, which occupy the portions on both sides of the upper end opening G of the first flow path 1000G in the upper end width direction of the filler module 1000, to the second heat exchange portion 402, which occupies substantially the entire width of the filler module 1000.

[0230] ​Specifically, in the front-rear direction in which the filler sheets are stacked, the first flow path 1000G is formed between the filler sheet 1000B and the filler sheet A, and the second flow path 1000W is formed between the filler sheet 1000A and the filler sheet 1000B. The distance between the filler sheet 1000A and the filler sheet 1000B is substantially uniform between the heat exchange portion 401 of the first flow path 1000G and the heat exchange portion 402 of the second flow path 1000W, that is, the filler sheet 1000A and the filler sheet 1000B are arranged substantially in parallel to each other at the portions of the first heat exchange portion 401 and the second heat exchange portion 402.

[0231] Further, for the filler sheet A and the filler sheet B, the upper section guide portion 200 of the first and second flow paths 1000G, 1000W is provided above the heat exchange portion 400 formed by the first and second heat exchange portions 401, 402 stacked.

[0232] In the present embodiment, by biasing the filler sheet 1000B and the filler sheet 1000A from the upper end opening G to the region of the portion of the first heat exchange portion 401 of the upper section guide portion 200 in opposite directions to each other, the first biasing portions 1100B, 1100A are formed, the distance between them is increased, and thus the first upper end opening portion 1100 of the first upper section guide portion 200G is formed. Further, for the upper section guide portion 200 of the filler sheet 1000A and the filler sheet 1000B, the filler sheet 1000A and the filler sheet 1000B are brought close to each other at the portion due to the formation of the first biasing portions 1100A, 1100B.

[0233] On the other hand, by biasing the filler sheet 1000A and the filler sheet 1000B from the upper end openings W1, W2 on both sides of the upper end opening G to the region of the portion of the second heat exchange portion 402 of the upper section guide portion 200 in opposite directions to each other, the second biasing portions 1200A, 1200B are formed, the distance between them is increased, and thus the second upper end opening portion 1200 of the second upper section guide portion 200W is formed. Further, for the upper section guide portion 200 of the filler sheet 1000B and the filler sheet 1000A, the filler sheet 1000B and the filler sheet 1000A are brought close to each other at the portion due to the formation of the second biasing portions 1200B, 1200A.

[0234] In the present embodiment, by forming the biasing portions in the upper sections of the filler sheets 1000A, 1000B as described above, the first upper end opening portion 1100 and the second upper end opening portion 1200 are formed in the upper section of the filler module 1000, and further, the first upper end opening G and the second upper end openings W1, W2 are formed in the upper end edges of the first upper end opening portion 1100 and the second upper end opening portion 1200. Further, in the first flow path 1000G, the first upper end opening G occupying a portion of the width of the filler module 1000 in the width direction is connected to the first heat exchange portion 401 occupying substantially the full width of the filler module 1000, and in the second flow path 1000W, the second upper end openings W1, W2 occupying a portion of the width of the filler module 1000 in the width direction are connected to the second heat exchange portion 402 occupying substantially the full width of the filler module 1000. Thus, in one unit of the second flow path 1000W formed by the filler sheets 1000A-1000B, the second upper end openings W1, W2 of the second flow path 1000W are connected to the common second heat exchange portion 402.

[0235] Further, the thickness dimension of the first and second upper end openings G, W1, W2 in the stacking direction of the filler module 1000 is greater than the distance in the stacking direction of the respective filler sheets 1000A, 1000B at the heat exchange portion 400.

[0236] In the present embodiment, in order to make the fluid in the first flow path 1000G and the second flow path 1000W uniform, a flow regulating sheet is further provided in the respective first and second upper section guide portions 200G, 200W.

[0237] As the first flow regulating sheet 1300G in the first flow path 1000G, it is provided in the first upper section guide portion 200G between the first upper end opening G and the first heat exchange portion 401, and the first upper section guide portion 200G functions to connect the first upper end opening G to the first heat exchange portion 401 occupying substantially the full width. Therefore, the first flow regulating sheet 1300G provided in the first upper section guide portion 200G is formed in a substantially isosceles trapezoidal shape, and has a plurality of flow guide grooves with the width gradually increasing from top to bottom.

[0238] Further, as the second flow regulating sheet 1300W in the second flow path 1000W, it is provided in the second upper section guide portion 200W between the second upper end openings W1, W2 and the second heat exchange portion 402, and the second upper section guide portion 200W functions to connect the second upper end openings W1, W2 to the second heat exchange portion 402 occupying substantially the full width. Therefore, the second flow regulating sheet 1300W provided in the second upper section guide portion 200W is formed in substantially two right-angled trapezoidal shapes, and has a plurality of flow guide grooves with the width gradually increasing from top to bottom.

[0239] In the present embodiment, as described above, since the front projection of the packing sheet 1000A, 1000B is substantially rectangular, the first upper end opening 1100 of the first upper section guide portion 200G formed by the first offset portion 1100B, 1100A is formed as an inverted substantially triangular shape; and the second upper end opening 1200 of the second upper section guide portion 200W formed by the second offset portion 1200A, 1200B is formed as an inverted substantially right-angled triangular shape located at the upper end left and right corner portions of the packing sheet 1000A, 1000B. At this time, the first upper end opening G and the second upper end openings W1, W2 are located at the upper end edge of the packing module 1000.

[0240] Accordingly, at the positions of the first and second rectifying sheets 1300G, 1300W corresponding to the first upper end opening 1100 and the second upper end opening 1200 of the first and second upper section guide portions 200G, 200W, longitudinal rectifying portions of inverted substantially triangular shapes and inverted substantially right-angled triangular shapes are also formed. The function of the longitudinal rectifying portions is to preliminarily separate the first and second upper section guide portions 200G, 200W of the first and second flow paths 1000G, 1000W, so as to ensure that the flow amount in each flow guide groove is substantially uniform in the oblique rectifying portions below.

[0241] Further, in the present embodiment, in addition to forming the first upper end opening 1100 and the second upper end opening 1200 by providing offset portions in the first and second upper section guide portions 200G, 200W, and providing the first and second rectifying sheets 1300G, 1300W, the first and second lower end guide portions 400G, 400W can also be formed by providing the same offset portions, and the third and fourth rectifying sheets 1300G', 1300W' can also be provided. Further, the same first and second lower end openings are formed.

[0242] Based on the packing module of the present embodiment, when a cooling tower is constructed, a plurality of packing modules can be arranged side by side in a substantially horizontal direction. Differences from the first to fourth embodiments will be described in detail below.

[0243] (Usage Example 1)

[0244] In the present embodiment, since the first upper end opening G of the first flow path 1000G is located at the middle portion in the width direction of the packing module 1000, and the second upper end openings W of the second flow path 1000W are located at both sides in the width direction of the packing module 1000, in the case of arranging the packing modules 1000 side by side, as shown in FIG. 10, a schematic diagram of usage example 1 of the packing module 1000 of the present embodiment is shown. Figure 27

[0245] ​In the present use example, the lower end of the partition plate 2005 (i.e. the first partition plate) provided above the filler module 1000 for separating the air flow path and the spray water flow path, and the sealing portion between the filler module 1000, are both located within the width direction dimension of the filler module, without the lower end of the partition plate 105 being located at the intersection portion of the filler modules as described above.

[0246] Specifically, the partition plate 2005 extends along the stacking direction, and the lower end of the partition plate 2005 corresponds to the connection portion of the first upper end opening G and the second upper end opening W in the width direction of the filler module 1000.

[0247] In this way, the sealing between the filler module 1000 and the partition plate 2005 is easier, and the spray flow path and the air flow path are separated as completely as possible, so that the cold air flowing from below the filler module 1000, after passing through the filler module 1000 to exchange heat with the hot water in the adjacent flow path, and being discharged above the filler module 1000, does not change in absolute humidity.

[0248] However, the air after heat exchange discharged above the filler module 1000 and the hot water in the adjacent flow path exchange heat, and becomes dry hot air, and in the case of maintaining absolute humidity, the air temperature rises, and the relative humidity significantly decreases.

[0249] In the present use example, the partition plate 2005' (i.e. the second partition plate) is also provided below the filler module 1000, and specifically, the partition plate 2005' extends along the stacking direction, and the lower end of the partition plate 2005' corresponds to the connection portion of the first lower end opening and the second lower end opening in the width direction of the filler module 1000. Therefore, in the cooling tower 2000, the spray hot water after passing through the filler module 1000 supplies as little moisture as possible to the cold air sucked below the filler module 1000. In the filler module 1000, the cold air and the hot water in the adjacent flow path are isolated from each other, and also do not supply moisture to the air flow path, and further, when the sucked cold air is discharged above the filler module 1000, due to the separation of the partition plate 2005, further avoids obtaining moisture from the spray portion.

[0250] Therefore, in this use example, by making the air flow path and the spray water as far as possible isolated within the cooling tower 2000, the moisture supplied to the intake air can be as little as possible; on the other hand, in the spray water flow path, because the valve plate 2009 in the closed state is arranged above the spray head, the hot air of the spray hot water is as far as possible mixed into the exhaust air, and below the filler module 1000 is also separated from the intake cold air by the partition plate 2005', so the spray hot water forms a closed flow path, and supplies moisture to the intake air and exhaust air of the cooling tower 2000 as far as possible. Therefore, even in winter in northern China, the mist discharged by the cooling tower 2000 can be greatly reduced.

[0251] (Use example 2)

[0252] In addition, the valve plate 2009 can also be arranged in a failure state (open or not arranged), as shown in the state of Figure 28 Even so, the cold air below the filler module 1000 is mixed with a small amount of water vapor above the partition plate 2005 after the cold air is discharged above the filler module.

[0253] Because the temperature of the cooled air increases after heat exchange, and the absolute humidity does not change, the saturation is low, on the other hand, the amount of moisture from the spray flow path itself is limited, so the cooled air with significantly reduced saturation can be effectively used to absorb the moisture released from the spray part. Except in the case of very low winter temperature, the cooling tower 2100 of this use example 2 can also effectively achieve the effect of eliminating mist.

[0254] In the above use examples 1 and 2, the first flow path 1000G is made as the air flow path, and the second flow path 1000W is made as the hot water spray flow path, so the part between the adjacent filler modules 1000 is limited to the range of the hot water spray flow path. In this case, the first flow path 1000G as the air flow path can make all the air taken in by the cooling tower 2000 flow through the first flow path 1000G as far as possible, while ensuring the airtightness between the lower end of the partition plate 2005 and the filler module 1000.

[0255] For the installation of the packing modules, there will inevitably be some gaps between the packing modules. If the packing modules are installed without gaps, the installation will be a problem. According to the packing module 1000 of the present embodiment, by setting the first upper end opening G at the middle of the width direction of the packing module 1000 and setting the second upper end opening W at both sides of the width direction of the packing module 1000, the adjacent upper end openings between the adjacent packing modules 1000 can be all the second upper end openings W, so that the second upper end openings W can be set as the inlet of the hot water spray. Thus, the problem of air leakage due to the installation gap between the packing modules 1000 can be effectively reduced. As in the first to fourth embodiments, there will inevitably be gaps between the packing modules 100, which are arranged in the air flow path, so that a part of the air flows directly through the gaps between the packing modules 100 without passing through the packing modules, which can cause a problem of reduced heat exchange efficiency. Furthermore, in the case where the gaps between the packing modules 100 are too large due to construction errors or mistakes, the air flow through the gaps between the packing modules 100 will be significantly increased, so that it is impossible to ensure the uniformity of the air resistance of the entire cooling tower, which will inevitably affect the uniformity of the heat exchange efficiency of the packing modules in the entire cooling tower.

[0256] The packing module 1000 of the present embodiment can solve the above problems.

[0257] (Usage Example 3)

[0258] As the usage example 3 of the packing module 1000 of the present embodiment, in addition to the advantages of the usage examples 1 and 2, the heat exchange efficiency of the cooling tower can be further improved, the cost of the packing module can be significantly reduced, and the convenience of installation and maintenance can be further enhanced. The details will be described below.

[0259] In the present usage example, as shown in Figure 29 , a cooling tower 3000 is built by using the packing module 1000, and the differences between the cooling tower 3000 and the previous embodiments will be described below.

[0260] In the cooling tower 3000, unlike the previous embodiments, a specified installation interval 3999 of 300-600 mm is provided between each packing module 1000, and a closing plate 3998 is preferably provided on the installation seat surface at the interval between the packing modules 1000. If the closing plate 3998 is not provided, the support frame serving as the installation seat of the packing module 1000 can be made to have a flat surface corresponding to the interval of the packing module 1000.

[0261] At this time, in contrast to the usage examples 1 and 2, the second flow path 1000W of the packing module 1000 is preferably used as the air flow path, and the first flow path 1000G is used as the flow path of the sprayed water.

[0262] Thus, the packing modules 1000 can be intentionally arranged with the installation intervals 3999 in designing the cooling tower 3000, and the installation intervals 3999 can allow workers to enter and move and investigate the state of the packing modules 1000 relative to each other when the packing modules 1000 are installed and maintained.

[0263] In particular, when the packing modules 1000 are installed, the packing modules 1000 are usually divided and stacked to a specified thickness because the packing modules 1000 are long in the stacking direction of the packing modules 1000, and a unit of the packing modules 1000 is formed by arranging the units in a straight line and close to each other in the stacking direction of the packing modules 1000 to form a whole row of the packing modules 1000. Therefore, in the installation construction of the cooling tower 3000, in order to ensure that the cooling tower 3000 has as little air and water leakage as possible, it is necessary to ensure that the units of the packing modules 1000 are in a straight line when installed. When the packing modules 1000 do not have the installation intervals 3999 between them in the lateral direction, it is almost impossible to adjust the straightness of the units of the packing modules 1000 in the longitudinal direction, and the installation accuracy must be accurately controlled when each unit is installed, so the installation efficiency needs to be improved.

[0264] In this regard, according to the present use case, because the installation intervals 3999 are arranged between the packing modules 1000 in the lateral direction, the operator can easily adjust the units of the packing modules 1000 by means of the installation intervals 3999 when installing the modules of the packing modules 1000 in the stacking direction. Even when a unit is damaged due to some special accident, the damaged unit can be easily moved and replaced by the units before and after it, and a new unit can be supplemented from the end of the stacking direction of the packing modules 1000, so that the repair can be completed.

[0265] When the closing plate 3998 is arranged in the installation interval 3999, the closing plate 3998 is preferably removable or erectable so as to be inactivated. At this time, because the second flow path 1000W is arranged as an air flow path, a large amount of air passes through only the installation interval 3999. At this time, the cooling efficiency of the hot water is greatly reduced, and some special needs in factory production can be met.

[0266] (Use Case 4)

[0267] Figure 30 is a schematic diagram of Use Case 4. In the present use case, similar to Use Case 3, intervals are arranged between the packing modules 1000 in the lateral direction, but ordinary packing modules F are further arranged in the intervals.

[0268] As the general filler module F, any filler module F can be used. For example, a filler module F in which a plurality of filler sheets are simply stacked to form a filler module F, which is the most widely used filler module F to date, can be used. In this case, no flow path is formed in the filler module F. Hot water is sprayed from the upper end opening into the thin sheet-like heat exchange space formed by the two adjacent filler sheets in the stacking direction, and cold air is drawn into the filler module F from the lower end opening of the filler module F by the fan of the cooling tower 4000, so that the air and the hot water directly contact each other to exchange heat.

[0269] As described above, in the present use example, the second flow path 1000W is used as the flow path in which hot water is sprayed, and the first flow path 1000G is used as the flow path in which air flows. In this way, in the present use example, the second flow path 1000W and the filler module F are simultaneously supplied with hot water, and the hot water flowing into the filler module 1000 through the second upper end openings Wl, W2 of the filler module 1000 exchanges heat with the air drawn into the filler module 1000 from the second lower end openings G' of the filler module 1000 in the filler module 1000, and the hot water sprayed into the filler module F directly exchanges heat with the air drawn into the filler module F from the lower end of the filler module F in the filler module F.

[0270] Thus, the air discharged upward from the first upper end opening G of the filler module 1000 becomes low-saturation hot air, and the hot air discharged from the upper end of the filler module F becomes saturated hot air.

[0271] On the other hand, the air resistance in the second flow path 1000W is extremely large due to the provision of the second upper end openings Wl, W2, and thus the amount of air actually discharged upward from the second upper end openings W of the filler module 1000 is extremely small, and the amount of air passing through the filler module F is extremely small.

[0272] Therefore, the low-saturation hot air mainly discharged from the first upper end opening G of the filler module 1000, the saturated hot air discharged from the filler module F, and the extremely small amount of saturated hot air discharged from the second upper end openings Wl, W2 of the filler module 1000 are mixed above the filler module. Thus, the unsaturated hot air is effectively used, the saturation of the mixed air is reduced, and the heat exchange efficiency of the cooling tower is greatly improved while ensuring sufficient fog elimination.

[0273] According to the packing module 1000 of the present embodiment, by arranging the first upper end opening G in the middle of the top end width direction and arranging the second upper end openings W (W1, W2) on both sides of the first upper end opening G, the packing module 1000 can be used more flexibly when used to build cooling towers 2000, 2100, 3000, 4000, etc., and the air passage and the hot water passage can also be arranged flexibly. In particular, when the first flow path 1000G connected with the first upper end opening G is used as an air flow path, the isolation of the air flow path and the hot water spray flow path is more complete. Thus, the relative humidity of the air after heat exchange can be reduced as much as possible to improve the effect of fog elimination, which is particularly suitable for the situation in winter in northern China.

[0274] However, the packing module 1000 provided by the present embodiment and the cooling tower having the packing module 1000 are not limited to the situation described in the present embodiment.

[0275] In the present embodiment, by arranging the packing module 1000 to include the upper section guide portion 200G, 200W in the upper section and the heat exchange portion 401, 402 below it, the first flow path 1000G and the second flow path 1000W formed by the alternately stacked packing sheets 1000A and 1000B, the first heat exchange portion 401 is contained in the first flow path 1000G, the second heat exchange portion 402 is contained in the second flow path 1000W, and the first heat exchange portion 401 and the second heat exchange portion 402 overlap to form the heat exchange portion 400.

[0276] Among them, the packing sheet 1000A has a bias portion 1100A biased to the front side of the stacking direction in the middle of the upper section guide portion, and has a bias portion 1100B biased to the rear side of the stacking direction on both sides of the upper section guide portion. The packing sheet 1000B has a bias portion 1200A biased to the rear side of the stacking direction in the middle of the upper section guide portion, and has a bias portion 1200B biased to the front side of the stacking direction on both sides of the upper section guide portion.

[0277] Therefore, by stacking the packing sheet 1000A and the packing sheet 1000B, the first upper end opening G is formed by the bias portions 1100A, 1100B of the packing sheet 1000A and the packing sheet 1000B formed in the middle of the upper section guide portion. The second upper end opening W is formed by the bias portions 1200A, 1200B of the packing sheet 1000B and the packing sheet 1000A formed on both sides of the upper section guide portion.

[0278] In the first flow path 1000G, the first upper end opening G is communicated with the first heat exchange portion 401 of the substantially full width dimension of the packing module 1000, and in the second flow path 1000W, the second upper end opening W is communicated with the second heat exchange portion 402 of the substantially full width dimension of the packing module.

[0279] In the present embodiment, a lower section guide portion is further provided below the heat exchange portion, and for the first and second flow paths 1000G, 1000W, the lower section guide portion is inverted with respect to the first and second upper section guide portions 200G, 200W, i.e. includes the corresponding biasing portion, and forms the first and second lower end openings, and further includes the inclined flow guide portion embedded in the guide portion including the biasing portion, which forms the first and second lower end opening portions, and the first and second heat exchange portions 401, 402, thereby forming the flow straightener 1300G', 1300W'. At this time, the same parts as the flow straightener 1300G, 1300W can be used for the flow straightener 1300G', 1300W', and the flow straightener 1300G', 1300W' can be inverted.

[0280] The flow straighteners 1300G, 1300W are located in the upper section guide portion of the filler module 1000, and in particular when guiding hot water flow, the sprayed hot water needs to be introduced from the first upper end opening G or the second upper end opening W (W1, W2) in the middle of the width direction to the first heat exchange portion 401 or the second heat exchange portion 402 of substantially full width, so the flow straightener is bent to form a lower end of the flow guide groove, and gradually flattens to make the guided fluid evenly distributed on the surface of the heat exchange portion of the filler sheet 1000A, 1000B. However, for the flow straighteners 1300G", 1300W", since they are in the lower section guide portion, when guiding the sprayed water to flow out of the filler module 1000, uniformity does not need to be considered, so the flattened part can be removed and only the bent guide flow path part is retained. In this way, it is also possible to avoid the situation that the low flow rate fluid, especially the sprayed hot water, is caused to be gathered by the impurities in the water due to the narrowing of the flow path by the flattened part of the upper end of the flow straightener 1300G', 1300W', and the long-term use of the filler module 1000 is blocked.

[0281]

Filler assembly 5100

[0282] As described above, when the packing module 1000 is installed, the packing module 1000 is usually segmented and stacked only to a specified thickness (for example, 1-3 meters), and the units forming the packing module 1000 are formed by arranging the units in a straight line and close to each other in the stacking direction of the packing module 1000 to form a whole packing module 1000. Therefore, in the installation construction of the cooling tower 3000, in order to ensure that the cooling tower 3000 has as little air and water leakage as possible, it is necessary to ensure that each unit of the packing module 1000 is in a straight line during installation. However, when the packing module 1000 is installed on the construction site, since the construction is carried out inside the cooling tower, it is often necessary to manually place each packing module 1000 in place, which is difficult to operate. Moreover, due to the inevitable reasons such as tolerance and deformation of the packing module 1000, the connecting surface between the two adjacent packing modules 1000 in the packing sheet stacking direction cannot be tightly attached together, and leakage is easy to occur. In cold winter, the water leaked into the air flow path will form ice, causing the air flow path to be blocked and even the equipment to be damaged.

[0283] To solve the above problems, as shown in Figure 31 and Figure 32 , the present embodiment provides a packing assembly 5100, which includes a packing module 1000 and a packing frame 5110 surrounding the outside of the packing module, and 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 completed in the factory, and the packing frame 5100 described above can be installed on the outside thereof.

[0284] For example, the length of the packing assembly 5100 in the packing sheet stacking direction is substantially equal to 1 / 2 of the corresponding direction length in the internal space of the cooling tower. Thus, as shown in Figure 33 and Figure 34 , the packing assembly 5100 and the packing assembly 5100' respectively occupy half of the length in the corresponding direction of the cooling tower, from Figure 34 , the packing assembly 5100 is installed into the cooling tower by using hoisting equipment or tools from the left side, and from Figure 34 , the packing assembly 5100' is installed into the cooling tower by using hoisting equipment or tools from the right side. In the above manner, when the cooling tower is built, each packing assembly 5100, 5100' can be quickly installed into the internal space of the cooling tower, greatly improving the speed of installing the packing layer of the cooling tower and reducing the leakage probability at the connecting surface between the packing modules.

[0285] In some embodiments, the packing frame 5100 described above can be made by welding, screwing or other means using square tubes, angle irons or other profiles. The components forming the packing frame 5100 can be located at each corner of the packing module 1000. In order to improve the strength of the packing frame 5100, at least one of horizontal, vertical and inclined reinforcement bars 5111 can also be provided.

[0286] As shown in Figs. 11 and 12, the packing assembly 5100 can further include an upper frame 5120 fixed on the upper side of the packing frame 5110. The upper frame 5120 can be used as a support structure of the spray system 5200, and the spray pipeline 5210 of the spray system can be fixed on the top of the upper frame 5120, and the spray heads 5220 can be installed at appropriate positions. Figure 31 Figure 32 As shown in Figs. 11 and 12, the packing assembly 5100 can further include an upper frame 5120 fixed on the upper side of the packing frame 5110. The upper frame 5120 can be used as a support structure of the spray system 5200, and the spray pipeline 5210 of the spray system can be fixed on the top of the upper frame 5120, and the spray heads 5220 can be installed at appropriate positions.

[0287] In addition, the upper frame 5120 described above can have a split structure, i.e. a plurality of split upper frames 5120 are assembled to form the 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 part and facilitates transportation and assembly.

[0288] As shown in Figs. 11 and 12, the packing assembly 5100 can further include an upper frame 5120 fixed on the upper side of the packing frame 5110. The upper frame 5120 can be used as a support structure of the spray system 5200, and the spray pipeline 5210 of the spray system can be fixed on the top of the upper frame 5120, and the spray heads 5220 can be installed at appropriate positions. Figure 33

[0289] The packing module of the preferred embodiment of the present application and the cooling tower having the same are described in detail above, but those skilled in the art can make various modifications, changes, combinations, etc. on the basis of the above, and these modifications, changes, combinations all fall within the protection scope of the claims of the present application.

[0290]

Packing assembly 6100

[0291] In the above embodiment, the assembly of the entire packing assembly needs to be completed in the factory, and then the packing assembly is transported to the construction site for installation in the cooling tower in a whole hoisting manner, which results in a large size of the packing assembly 5100 and inconvenience in construction, transportation and installation.

[0292] However, if the above frame 5110 is simply segmented, other problems will be caused: it is not easy to form an effective seal between the packing segments, the flow path between the two adjacent packing segments is blocked or plugged, and cannot be effectively utilized; and the integral frame also adversely affects the assembly of the packing sheets.

[0293] 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 35 The 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.

[0294] 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'.

[0295] 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.

[0296] To address the aforementioned technical problems, the inventors of this application propose 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.

[0297] Figure 36 This is a front view of a packing assembly 6100 formed by installing the packing module of the fifth embodiment of the present invention in a packing frame of another structure. Figure 37 yes Figure 36 A magnified view of a portion of the image;

[0298] like Figure 36 and 37As shown, the filler assembly 6100 includes a lower bracket 6110 and an upper bracket 6120, and a tensioning assembly 6130 that tension and connects the lower bracket 6110, the filler module 1000 and the upper bracket 6120.

[0299] The filler module is assembled by means of bonding, ultrasonic welding, etc. Figure 35 The filler module 1000 is placed on the lower bracket 6110, and the upper bracket 6120 is placed on the upper side of the filler module 1000. A sealing strip 6142 is arranged between the upper bracket 6120 and the first and second upper partition areas E1, E2, and between the lower bracket 6110 and the first and second lower partition areas E1', E2'. The length and width of the sealing strip 6142 are suitable for covering the corresponding partition areas.

[0300] The upper end of the tensioning assembly 6130 is connected with the upper bracket 6120, and the lower end is connected with the lower bracket 6110, so as to tension and press the upper bracket 6120 and the lower bracket 6110 towards the filler module 1000 in the vertical direction, and to make the sealing strip 6142 deformed to a certain extent, so as to form an effective partition seal between the first and second upper end openings and between the first and second lower end openings. The tensioning assembly 6130 can be, for example, a combination of an elongated stud and a nut, or can be realized by a steel wire rope.

[0301] As shown in Figure 37 The upper bracket 6120 includes a first upper support part 6121 and a second upper support part 6122, the first upper support part 6121 corresponding to the first upper partition area E1, and the second upper support part 6122 corresponding to the second upper partition area E2. The extension direction of the first and second upper support parts 6121, 6122 is the same as the stacking direction of the filler sheets. The length of the first and second upper support parts 6121, 6122 is substantially the same as the thickness of the filler module 1000 in the stacking direction.

[0302] The lower bracket 6110 includes a first lower support part 6111 and a second lower support part 6112, the first lower support part 6111 corresponding to the first lower partition area E1', and the second lower support part 6112 corresponding to the second lower partition area E2'. The extension direction of the first and second lower support parts 6111, 6112 is the same as the stacking direction of the filler sheets. The length of the first and second lower support parts 6111, 6112 is substantially the same as the thickness of the filler module 1000 in the stacking direction.

[0303] Figure 38 is a schematic view of the outer shape of the filler assembly of the present embodiment;

[0304] As shown in Figure 38As shown, the upper bracket 6120 further comprises a plurality of upper cross beams 6123, which are respectively fixedly connected with the first upper support part 6121 and the second upper support part 6122, and extend along the width direction of the filler module 1000. The upper cross beams 6123 can be provided with a suitable number according to the stacking thickness of the filler module, so as to be able to exert uniform force on the sealing strip 6142, and avoid leakage caused by uneven force on the sealing strip.

[0305] Correspondingly, the lower bracket 6110 comprises a plurality of lower cross beams 6113, which are respectively fixedly connected with the first lower support part 6111 and the second lower support part 6112, and extend along the width direction of the filler module 1000.

[0306] The lower cross beams 6113 correspond in position to the upper cross beams 6123. The upper end of the tensioning assembly 6130 is connected with the end of the upper cross beam 6123, and the lower end is connected with the end of the lower cross beam 6113.

[0307] The filler assembly 6100 of the present embodiment realizes the modularization of the filler module 1000 through the lower bracket 6110 and the upper bracket 6120, and only needs to stack the upper bracket 6120, the filler module 1000 and the lower bracket 6110 up and down, thereby improving the installation efficiency; and the extrusion force can be transmitted to the sealing strip 6142 through the lower bracket 6110 and the upper bracket 6120 by the tensioning assembly 6130, so that the sealing strip 6142 is deformed to play a partitioning role on the openings on the left and right sides of the partitioning area.

[0308] The filler assembly 6100 of the present embodiment further comprises a water separation groove 6150 connecting the partition plate 2005 and the upper bracket 6120. The water separation groove 6150 is connected with the upper bracket 6120, and comprises a first side wall 6151 and a second side wall 6152, and an accommodating groove 6153 for accommodating the lower end edge of the partition plate 2005 is formed between the first side wall 6151 and the second side wall 6152 and opens upward. Further, the first side wall 6151 is located on the side close to the spraying space 205a, and the height of the first side wall 6151 is lower than the height of the second side wall 6152, so that the water falling from the spraying space 205a into the accommodating groove 6153 can overflow from the side where the first side wall 6151 is located, and cannot flow into the air induction space 205a, thereby avoiding icing.

[0309] In the present embodiment, the water separation groove 6150 is fixedly connected with the first upper support part 6121 and the second upper support part 6122 in the same extension direction.

[0310] Figure 39 is a schematic view of the assembly structure of a plurality of filler assemblies 6100, which shows the top structure of the filler assembly 6100;

[0311] Figure 40 is a schematic view of the connection structure of two filler assemblies 6100a, 6100b adjacent in the stacking direction; Figure 41 is a schematic view of the assembly structure of a plurality of filler assemblies 6100, which shows the bottom structure of the filler assemblies.

[0312] As shown in Figures 38-41 , the filler assemblies 6100 are assembled as single units in the production workshop as shown in Figure 38 . When installed in the cooling tower, a plurality of filler assemblies 6100a, 6100b, 6100c, 6100d are connected in sequence in the stacking direction, thus improving the convenience of transportation and installation.

[0313] As shown in Figure 40 , the filler assembly 6100a and the filler assembly 6100b are brought together in the stacking direction. The first upper support part 6121a of the filler assembly 6100a and the first upper support part 6121b of the filler assembly 6100b have the same extension direction, and a sealing gasket 6160 is placed and compressed between the end faces of the two, thus playing a sealing role at the connection (corresponding to the first partition area E1). Preferably, a bolt assembly can be provided at the connection end face to connect and compress the sealing gasket 6160.

[0314] Similarly, the second upper support part 6122a of the filler assembly 6100a and the second upper support part 6122b of the filler assembly 6100b have the same extension direction, and a sealing gasket 6160 is placed and compressed between the end faces of the two, thus playing a sealing role at the connection (corresponding to the second partition area E2).

[0315] For the connection between the filler assembly 6100a and the filler assembly 6100b, a horizontal tie 6150 as shown can be used, one end of which is connected to the filler assembly 6100a and the other end of which is connected to the filler assembly 6100b, to achieve reliable connection between the two. The position of the above-mentioned horizontal tie 6150 has multiple choices, for example, it can be tightened through the upper cross beam 6123a of the filler assembly 6100a and the upper cross beam 6123b of the filler assembly 6100b. At this time, in order to facilitate installation, the upper cross beam 6123a can be arranged close to the end part of the filler assembly 6100a in the stacking direction.

[0316] In this embodiment, the flow path at the connection between the filler assembly 6100a and the filler assembly 6100b in the stacking direction is not shielded, and the first partition area E1 and the second partition area E2 at the connection are effectively sealed, which, together with the gluing and other means, can ensure the effective operation of the flow path at the connection and improve the overall heat exchange area of the cooling tower.

[0317] As shown in Figure 41As shown, the first lower support part 6111a and the second lower support part 6112a of the filler assembly 6100a and the first lower support part 6111a and the second lower support part 6112b of the filler assembly 6100b can also be connected in the manner as described above, and a sealing gasket 6160 is arranged at the connection to achieve sealing at the corresponding position, which will not be described again.
