In order to solve this technical problem, the present embodiment provides an anti-icing water-saving fog-eliminating cooling tower. SUMMARY

[0107] Hereinafter, a preferred embodiment of the present application will be described in detail with reference to the accompanying drawings.

[0108] [First Embodiment]

[0109] Hereinafter, the filler module 1 of the first embodiment of the present application will be described in detail.

[0110] [Filler Module 1]

[0111] In the present embodiment, the filler module 1 includes the filler sheet A and the filler sheet B alternately and laminated at a prescribed interval d, and the first flow path Rl and the second flow path R2 are formed by the laminated filler sheets A and B in the filler module 1.

[0112] The upper segment guide portion 200 and the lower segment guide portion 300 are formed in the upper segment and the lower segment of the filler module 1, respectively, and the heat exchange portion 400 is formed in the middle segment.

[0113] [Upper Segment Guide Portion 200]

[0114] The upper end of the upper-stage guide portion 200 is formed with guide openings by alternately arranging the upper end portions of the rectangular filler pieces A and B, as follows.

[0115] The upper end portions of the filler pieces A on the side perpendicular to the stacking direction (left side in the figure) are offset to the side of the stacking direction (back side in the figure), and the upper end portions of the filler pieces B are offset to the side opposite to the stacking direction (front side in the figure), so that on the stacking direction from the front side to the back side in the figure, the left-side upper end portions of the filler pieces A-B are in contact with each other, and the left-side upper end portions of the filler pieces B-A are open to each other to form first upper end openings 210. For the filler module 1, a plurality of the first upper end openings 210 are arranged side by side in the stacking direction. The first upper end openings 210 are in communication with the first flow paths R1 formed between the filler pieces B-A.

[0116] The upper end portions of the filler pieces A on the side perpendicular to the stacking direction (left side in the figure) are offset to the side of the stacking direction (back side in the figure), and the upper end portions of the filler pieces B are offset to the side opposite to the stacking direction (front side in the figure), so that on the stacking direction from the front side to the back side in the figure, the left-side upper end portions of the filler pieces A-B are in contact with each other, and the left-side upper end portions of the filler pieces B-A are open to each other to form first upper end openings 210. For the filler module 1, a plurality of the first upper end openings 210 are arranged side by side in the stacking direction. The first upper end openings 210 are in communication with the first flow paths R1 formed between the filler pieces B-A.

[0117] In the upper-stage guide portion 200, a left upper path rectifying piece 230 is embedded in the first flow path R1 between the first upper end openings 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 openings 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 (first heat exchange portion 401 of the first flow path).

[0118] In the present embodiment, the left upper path rectifying piece 230 has a meandering shape in a lateral cross section perpendicular to the stacking direction, and the stacking direction sides of the meandering shape, i.e., the back side and the front side, are in abutment with the front surface of the filler piece A and the back surface of the filler piece B, respectively, which sandwich the left upper path rectifying piece 230. Thus, in the first flow path R1 formed between the first upper end openings 210 and the heat exchange portion 400, a guide portion is formed which guides the width from the first upper end openings 210 to the full width of the heat exchange portion 400 which is substantially the width of the filler pieces A and B.

[0119] In the upper section guide portion 200, a right upper path rectification fin 240 is embedded in the second flow path R2 between the second upper end opening 220 formed by the filler pieces A-B and the heat exchange portion 400 surrounded by the filler pieces A-B. The upper end of the right upper path rectification fin 240 matches the width of the second upper end opening 220, and the width gradually increases from the upper end to the lower end. The lower end of the right upper path rectification fin 240 matches the width of the heat exchange portion 400 (the first heat exchange portion 402 of the second flow path).

[0120] In the present embodiment, the right upper path rectification fin 240 has a meandering shape in a lateral cross section perpendicular to the stacking direction. The meandering shape has a back side on one side of the stacking direction abutting against the front surface of the filler piece B sandwiching the right upper path rectification fin 240, and a front side on the other side of the stacking direction abutting against the back surface of the filler piece A sandwiching the right upper path rectification fin 240. Thus, in the second flow path R2 formed between the second upper end opening 220 and the heat exchange portion 400, a guide portion is formed that guides from the width of the second upper end opening 220 to the full width of the heat exchange portion 400 that is approximately the width of the filler pieces A and B.

[0121]

Lower section guide portion 300

[0122] In the lower section guide portion 300, the guide openings are formed by the lower end portions of the filler pieces A and B arranged alternately. Specifically, as follows.

[0123] In the lower end portion of the filler piece A on one side (the left side in the drawing) perpendicular to the stacking direction, the lower end portion is biased toward the other side (the back side in the drawing) of the stacking direction. In the lower end portion of the filler piece B on the other side (the front side in the drawing) perpendicular to the stacking direction, the lower end portion is biased toward the one side (the 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 filler pieces A and B on the left side abut against each other, and the lower end portions of the filler 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 R1 formed between the filler pieces B and A.

[0124] In the lower end portion of the filler piece A on one side (the right side in the drawing) perpendicular to the stacking direction, the lower end portion is biased toward the other side (the front side in the drawing) of the stacking direction. In the lower end portion of the filler piece B on the other side (the back side in the drawing) perpendicular to the stacking direction, the lower end portion is biased toward the one side (the back 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 filler pieces B and A on the left side abut against each other, and the lower end portions of the filler pieces A and B on the left side are open to each other to form a second lower end opening 320. Thus, the second lower end opening 320 communicates with the second flow path R2 formed between the filler pieces A and B.

[0125] In the lower section guide portion 300, a left lower path rectification fin 330 is embedded in the first flow path R1 between the first lower end opening 310 formed by the filler pieces B and A and the heat exchange portion 400 surrounded by the filler pieces B and A. The lower end of the left lower path rectification fin 330 matches the width of the first lower end opening 310, and the width gradually increases from the lower end to the upper end. The upper end of the left lower path rectification fin 330 matches the width of the heat exchange portion 400.

[0126] In the present embodiment, the right lower rectifying fin 340 is in a bent shape in a lateral cross section perpendicular to the stacking direction, and the bent back side abuts against the front surface of the filler sheet B, and the front side abuts against the back 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 section 400 surrounded by the filler sheets A-B, a guide section is formed that guides the full width of the heat exchange section 400 from the width of the second lower end opening 320 to approximately the width of the filler sheets A, B.

[0127] In the lower section guide section 300, the right lower rectifying fin 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 section 400 surrounded by the filler sheets A-B. The lower end of the right lower rectifying fin 340 matches the width of the second lower end opening 320, and the width gradually increases from the top to the bottom, and the lower end corresponds to the width of the heat exchange section 400.

[0128] In the present embodiment, the right lower rectifying fin 340 is in a bent shape in a lateral cross section perpendicular to the stacking direction, and the bent back side abuts against the front surface of the filler sheet B, and the front side abuts against the back 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 section 400 surrounded by the filler sheets A-B, a guide section is formed that guides the full width of the heat exchange section 400 from the width of the second lower end opening 320 to approximately the width of the filler sheets A, B.

[0129] 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 are formed in the filler module 1, which are isolated from each other and are alternately stacked. Hereinafter, the configuration of the first flow path R1 and the second flow path R2 will be described in detail.

[0130]

[0131] In the present embodiment, for the filler module 1, in the stacking direction from the front side to the back side in the drawing, the first flow path R1 is formed between the adjacent filler sheet B and the filler sheet A located at the back side of the filler sheet B, that is, between the filler sheet B-A.

[0132] As shown in the drawing, the first flow path R1 includes, from the top to the bottom, the first upper end opening 210 located at the left side of the upper end of the filler module 1, the left upper section guide section 201 located in the upper section guide section 200 and filled and supported between the filler sheets B, A by the left upper rectifying fin 230, the first heat exchange section 401 formed as a flat cavity between the filler sheets B-A at the heat exchange section 400 in the stacking direction, the left lower section guide section 301 located in the lower section guide section 300 and filled and supported between the filler sheets B, A by the left lower rectifying fin 330, and the first lower end opening 310 located at the left side of the lower end of the filler module 1.

[0133] Thus, in the present embodiment, one unit of the first flow path Rl in which a flat- shaped cavity is formed between the adjacent filler sheet B and the filler sheet A is formed, 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 on the same side in the direction perpendicular to the stacking direction.

[0134] [Units of the second flow path R2]

[0135] In the present embodiment, for the filler module 1, in the stacking direction from the front side to the rear side in the drawing, a unit of the second flow path R2 is formed between the adjacent filler sheet A and the filler sheet B located on the rear side of the filler sheet A, i.e., the filler sheet A-B.

[0136] As shown in the drawing, the second flow path R2 includes, from the top to the bottom, the second upper end opening 220 located on 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 flow rectifying sheet 240; the second heat exchange portion 402 in which a flat-shaped cavity is formed between the filler sheets A and 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 flow rectifying sheet 340; and the second lower end opening 320 located on the right side of the lower end of the filler module 1.

[0137] Thus, in the present embodiment, one unit of the first flow path Rl in which a flat- shaped cavity is formed between the adjacent filler sheet A and the filler sheet B is formed, 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 on the same side in the direction perpendicular to the stacking direction.

[0141] As described above, in the stacking direction of the filler sheets A and B, the first flow path Rl and the second flow path R2 in which flat-shaped cavities are formed between the filler sheet B-A and the filler sheet A-B, respectively, are formed, and thus the first flow path Rl and the second flow path R2 are alternately stacked. Thus, for the filler module 1, the first and second upper end openings 210 and 220 which are parallel to each other in the direction perpendicular to the stacking direction are formed at the upper end edges.

[0142] In the present embodiment, as shown in the figure, the first upper end opening 210 is formed on the left side, and since the left upper end portions of the filler pieces A are biased toward the back side in the figure, while the left upper end portions of the filler pieces B are biased toward the opposite front side in the figure, the left upper end portions of the filler pieces A-B are in contact with each other, while the left upper end portions of the filler pieces B-A are open to each other. Thus, the strip-shaped openings in which the left upper end portions of the filler pieces B-A are open to each other are arranged in parallel in the stacking direction via the left upper end portions of the filler pieces 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 pieces is not taken into consideration, the entire area corresponding to the side (left side in the figure) of the upper end of the filler module 1 which is perpendicular to the stacking direction is formed as the open first upper end opening 210.

[0143] Likewise, 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 portions of the filler pieces B are biased toward the back side in the figure, while the right upper end portions of the filler pieces A are biased toward the opposite front side in the figure, so that the right upper end portions of the filler pieces B-A are in contact with each other, while the right upper end portions of the filler pieces A-B are open to each other. Thus, the strip-shaped openings in which the right upper end portions of the filler pieces A-B are open to each other are arranged in parallel in the stacking direction via the right upper end portions of the filler pieces 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 pieces is not taken into consideration, the entire area corresponding to the other side (right side in the figure) of the upper end of the filler module 1 which is perpendicular to the stacking direction is formed as the open second upper end opening 220.

[0144] On the other hand, as for the first and second upper end openings 210, 220 which are formed in parallel to each other in the stacking direction on the lower end edge.

[0145] 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, while 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, while 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 in parallel in the stacking direction via the left lower end portions of the filler pieces A-B which 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 taken into consideration, the entire area corresponding to the side (left side in the figure) of the lower end of the filler module 1 which is perpendicular to the stacking direction is formed as the open first lower end opening 310.

[0146] Likewise, 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 portion of the filler sheet B is biased toward the back side in the drawing, and the right lower end portion of the filler sheet A is biased toward the opposite front side in the drawing, so that the right lower end portions of the filler sheet B-A are in contact with each other, and the right lower end portions of the filler sheet A-B are open to each other. Thus, the strip-shaped opening in which the right lower end portions of the filler sheet A-B are open to each other is arranged in parallel in the stacking direction via the right lower end portions of the filler sheet B-A which are in contact with each other, and the entire second lower end opening 320 is formed. In the case where the thickness of the filler sheet is not considered, the entire area on the other side (the right side in the drawing) of the lower end of the filler module 1 which is perpendicular to the stacking direction forms the open second lower end opening 320.

[0147]

Opening of flow path

[0148] The first flow path Rl will be further described in detail in the direction from the top to the bottom.

[0149] 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 which 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 sheet A-B are in contact with each other are divided into a plurality of units. In the left upper guide portion 201, after passing through the portions in which the left upper end portions of the filler sheet A-B are in contact with each other, the units of the first flow path Rl are separated from each other in the stacking direction, and on the 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 sheet A, B, that is, the thickness decreases and the width increases, and the unit of the first heat exchange portion 401 of the flat heat exchange space defined by the filler sheet B-A which enters the heat exchange portion 400 from the upper guide portion 200.

[0150] When continuing downward from the heat exchange portion 400 to the lower guide portion 300, in contrast to the case in the upper guide portion 200, the units of the first flow path Rl downward from the flat shape of substantially the width of the filler sheet A, B, on the one hand, the size in the stacking direction gradually increases, and on the other hand, the size perpendicular to the stacking direction gradually decreases to the width of the second lower end opening 220, that is, the thickness increases and the width decreases, and at the lower left guide portion 301, the portions in which the left lower end portions of the filler sheet A-B are in contact with each other are merged to reach the first lower end opening 310.

[0151] Thus, in the first flow path Rl, the entire flow path from the first upper end opening 210 through the upper guide portion 200, the heat exchange portion 400, the lower guide portion 300 to the first lower end opening 310, the cross-sectional area of which is theoretically substantially constant.

[0152] As for the second flow path R2, which is rotationally symmetrical to the first flow path Rl, further detailed description will be given below.

[0153] As described above, the second flow path R2 at the upper end of the packing module 1 corresponds to the formation of the second upper end opening 210 in the entire area on the right side in the direction perpendicular to the stacking direction, and at the second upper end opening 210, the portions where the right side upper end portions of the packing pieces B-A are adhered to each other are divided into a plurality of units. In the right upper section guide portion 202, after passing through the portions where the right side upper end portions of the packing pieces B-A are adhered to 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 gradually decreases in the stacking direction, and on the other hand, the size gradually increases in the direction perpendicular to the stacking direction to the width of the packing pieces A, B to form a flat shape, that is, the thickness decreases and the width increases, and the units of the second heat exchange portion 402 of the flat heat exchange space defined by the packing pieces A-B from the upper section guide portion 200 into the heat exchange portion 400.

[0154] When continuing downward from the heat exchange portion 400 to the lower section guide portion 300, in contrast to the case in the upper section guide portion 200, the units of the second flow path R2 downward from the flat shape of the width of the packing pieces A, B, on one hand, the size gradually increases in the stacking direction, and on the other hand, the size gradually decreases in the direction perpendicular to the stacking direction to the width of the second lower end opening 220, that is, the thickness increases and the width decreases, and in the right lower section guide portion 302, the portions where the right side lower end portions of the packing pieces B-A are adhered to each other are merged to reach the second lower end opening 320.

[0155] Thus, in the second flow path R2, the entire section flow path from the second upper end opening 220, through the upper section guide portion 200, the heat exchange portion 400, the lower section guide portion 300, and to the second lower end opening 320, the cross-sectional area of the flow path is substantially constant in theory.

[0156] As described above, in the present embodiment, the first and second upper end openings 210, 220 as the upper end openings of the first and second flow paths Rl, R2, the sum of the opening areas is consistent with the sum of the cross-sectional areas of the flow paths of the respective portions from the top to the bottom. Similarly, the first and second lower end openings 310, 320 as the lower end openings of the first and second flow paths Rl, R2, the sum of the opening areas is consistent with the sum of the cross-sectional areas of the flow paths of the respective portions from the top to the bottom, that is, the opening areas as the upper end and the lower end of the packing module 1 are consistent with the horizontal cross-sectional area of the packing module 1, so that the fluid throughput and the passing efficiency of the respective flow paths 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.

[0157]

Rectifier sheet

[0158] Thus, when the rectifier fins 230, 240, 330, 340 are inserted into the respective first and second flow paths R1, R2, i.e., when the rectifier fins 230, 240, 330, 340 are inserted into the respective first and second flow paths R1, R2, since the rectifier fins 230, 240, 330, 340 are formed in a curved shape, and the extension direction of the curved protrusions corresponds to the extension path of the first and second flow paths R1, R2, respectively, the thickness of the rectifier fins 230, 240, 330, 340 is substantially different from the cross-sectional area of the first and second flow paths R1, R2, and thus does not affect the passing efficiency of the first and second flow paths R1, R2.

[0159] In addition, 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 R1, R2, are arranged side by side in a direction perpendicular to the stacking direction, and have substantially the same width, and thus the left upper path rectifier fin 230 and the right upper path rectifier fin 240, which are located in the left upper guide portion 201 and the right upper guide portion 202, respectively, have substantially the same accommodation space configuration, and are arranged in a rotational symmetry manner, and thus the same components can be used to configure the left upper path rectifier fin 230 and the right upper path rectifier fin 240.

[0160] Similarly, the first and second lower end openings 310, 320, which are the lower end openings of the first and second flow paths R1, R2, are arranged side by side in a direction perpendicular to the stacking direction, and have substantially the same width, and thus the left lower path rectifier fin 330 and the right lower path rectifier fin 340, which are located in the left lower guide portion 301 and the right lower guide portion 302, respectively, have substantially the same accommodation space configuration, and are arranged in a rotational symmetry manner, and thus the same components can be used to configure the left lower path rectifier fin 330 and the right lower path rectifier fin 340.

[0161] Further, in the present embodiment, by making the heights of the upper guide portion 200 and the lower guide portion 300 substantially the same, the accommodation space configurations of the rectifier fins 230, 240, 330, 340 are made substantially the same, and thus the same components can be used to configure 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 pieces A, B and the common rectifier fins are needed, and the production cost of the filler module 1 is significantly reduced, and the assembly efficiency is significantly improved.

[0162] In the present embodiment, the same filler sheet A and filler sheet B as in the first embodiment can be used. In the first embodiment, the left upper path rectifying fin 230, the right upper path rectifying fin 240, the left lower path rectifying fin 330, and the right lower path rectifying 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. The left upper section guide portion 201 and the left lower section guide portion 301 are both on the same side (the left side in the first embodiment) of the filler module 1, and the right upper section guide portion 202 and the right lower section guide portion 302 are both on the other same side (the right side in the first embodiment) of the filler module 1, that is, the fluid flowing into / introduced from one side (the left side) of the width direction of the filler module 1 forms the flow path Rl of substantially the full width of the filler module 1 at the heat exchange portion 400, and the fluid flowing into / introduced from the other side (the right side) of the width direction of the filler module 1 forms the flow path R2 of substantially the full width of the filler module 1 at the heat exchange portion 400, the thickness of Rl and R2 in the stacking direction is half the thickness of each opening in the stacking direction, and the sum of the thicknesses of Rl and R2 is equivalent to half 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 discharged 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 discharged from the first upper end opening 210 at the left upper end, becoming the first flow path Rl; the same applies to 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 the first upper end opening 210 and the first lower end opening 310 as the upper and lower end openings of the first flow path Rl are provided on different sides of the filler module, and the second upper end opening 220 and the second lower end opening 320 as the upper and lower end openings of the second flow path R2 are also provided on different sides of the filler module. This has no substantial effect on the function of the filler module 1 of having two flow paths Rl and R2 provided across the filler sheet A and B, and the upper and lower end openings, and is an equivalent embodiment to the first embodiment described above.

[0163] Of course, the first upper end opening 210 and the first lower end opening 310 as the upper and lower end openings of the first flow path Rl can also be provided on different sides of the filler module, and the second upper end opening 220 and the second lower end opening 320 as the upper and lower end openings of the second flow path R2 can also be provided on different sides of the filler module. This has no substantial effect on the function of the filler module 1 of having two flow paths Rl and R2 provided across the filler sheet A and B, and the upper and lower end openings, and is an equivalent embodiment to the first embodiment described above.

[0164] [Second Embodiment]

[0165] 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.

[0166] like Figures 10 to 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'.

[0167] 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'.

[0168] As can be seen, compared with the filler module 1 of the first embodiment of the present application, in the present embodiment, by removing the rectifier fins in the right upper section guide portion 202 and the right lower section guide portion 302 of the second flow path R2, and using the second flow path R2 as a cold air flow path only, the cold air drawn into the second flow path R2 can obtain the smallest wind resistance possible. And, because the air flow does not have the influence of gravity as water flow does, even without the rectifier fins, when ensuring the same air flow through the second flow path R2 as the first embodiment, the same cooling efficiency as the filler module 1 of the first embodiment can be obtained, however, because there are no rectifier fins in the second flow path R2, the wind resistance of the air introduced into the filler module 1' is smaller. When using an active exhaust cooling tower, the power required by the fan at the top of the cooling tower is lower, and the power can be effectively saved. And, because the filler module 1' of the present embodiment can obtain smaller wind resistance, it is more suitable for a cooling tower that does not have a fan and uses a passive air suction method, such as a hyperbolic cooling tower.

[0169] In the present embodiment, as a preference, the upper and lower end openings of the first flow path R1 and the second flow path R2 are located on the same side of the filler module width direction, and further, by the arrangement of the filler sheets A, B, a good water separation structure can be formed, and the water in the first flow path R1 provided with the left upper path rectifier fin 230 and the left lower path rectifier fin 330 is prevented from invading the air flow path of the second flow path R2 through the gap. Details are described below.

[0170] Further, in the present embodiment, as shown in Figure 11 the upper end portion of the filler sheet A of the filler module 1', at the left side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, i.e. the first upper end opening 210 side, the base position O A of the heat exchange portion 400 of the filler sheet A is biased to the rear side by a distance of d / 2, and a rear half of the first upper end opening 210 formed by the filler sheet A is formed. Further, a left sealing edge portion 215A is formed at a position biased to the front side by a distance d from the rear half of the first upper end opening 210, i.e. from the base position O A of the heat exchange portion 400 of the filler sheet A, and the left sealing edge portion 215A extends linearly in the up and down direction.

[0171] Further, at the upper end portion of the filler sheet A, at the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, i.e. 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 rear side formed by the filler sheet A is formed by biasing to the front side by a distance of d / 2.

[0172] Further, the upper end portion of the filler sheet B adjacent to the front side of the filler sheet A in the stacking direction, at the left side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, i.e. the first upper end opening 210 side, is offset by a distance d / 2 from the base position O of the heat exchange portion 400 of the filler sheet B B by a distance d / 2 to the front side, thereby forming the front half of the first upper end opening 210 composed of the filler sheet B. Further, at the left end edge of the filler sheet B, a left edge sealing portion 215A is formed which is offset by a distance d from the front half of the first upper end opening 210 to the rear side, i.e. from the base position O of the heat exchange portion 400 of the filler sheet B to the rear side. B At the position offset by d / 2 to the rear side, the left edge sealing portion 215A is formed. The left edge sealing portion 215A extends linearly in the up-down direction.

[0173] Further, at the upper end portion of the filler sheet B, at the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, i.e. the second upper end opening 220 side, a rear half of the second upper end opening 210 of the front side second flow path R2 composed of the filler sheet B is formed which is offset by a distance d / 2 to the rear side.

[0174] Thus, when the filler sheet A and the filler sheet B adjacent to the front side thereof are assembled by contacting each other, at the left side of the first upper end opening 210, the left edge sealing portion 215A of the filler sheet A and the left edge sealing portion 215B of the filler sheet B adjacent to the front side thereof are brought together from the top down.

[0175] Thus, for the first flow path R1 formed by the filler sheet A and the filler sheet B adjacent to the front side thereof, the flow inlet, i.e. the first upper end opening 210, has a thickness of 2d, and the left edge sealing portion 215 thereof is formed by the left edge sealing portion 215A and the left edge sealing portion 215B which are offset from each other and brought together. The left edge sealing portion 215 can easily form a sealing structure when performing a joint seal. When the first flow path R1 is used as a flow path for hot water shower, since the hot water is poured from the front and rear arranged first upper end openings 210 located at the left side of the filler module 1', the hot water is not easy to seep out from the left edge sealing portion 215 when the hot water is guided into the heat exchange portion 400.

[0176] 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 flows along the rear wall surface of the filler sheet B and the front wall surface of the filler sheet A in the front and rear sides within the heat exchange portion 400 under the action of its own gravity, and does not easily intrude into the right side edge sealing portion of the filler module 1'. Thus, the sealing requirement for the right side edge sealing portion is significantly reduced.

[0177] Specifically, in the present embodiment, for the lower segment guide portion 300, if the lower segment guide portion 300 is rotated 180° with the horizontal axis perpendicular to the stacking direction as the center, the structure thereof is the same as that of the upper segment guide portion 200. For the lower segment guide portion 300, as with the structure of the upper segment guide portion 200, the lower end edges of the filler sheet A and the filler sheet B adjacent to the front side thereof are offset and arranged, thereby forming continuous left edge seal portions 215A, 215B from the left side edges of the filler sheet A, the filler sheet B, and the left side edge of the heat exchange portion 400 upward, and thus water leakage from the left edge seal 215 can be effectively avoided, particularly, water leakage from the left edge seal 215 at the portions of the upper segment guide portion 200 and the lower segment guide portion 300.

[0178] Further, in the present embodiment, for the edge seal portion 215 formed by the left edge seal portions 215A, 215B, any joining method can be used, and from the viewpoint of assembly convenience, it is preferable to join the edge seal portion 210 by pressure welding. This is because, when the filler sheets A, B and the rectifier sheets 230, 330 are assembled using a device, the filler sheet B and the filler sheet B adjacent in the front-rear direction are aligned, and at this time, since the filler sheets A, B are offset to be close 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 device in this state to weld the edge seal portion 215 and the right side portions of the upper and lower end edges of the filler sheets B-A.

[0179] Thus, by inserting the rectifier sheets 230, 330 between the filler sheets B-A and welding the edge seal portion 215 and the right side portions of the upper and lower end edges of the filler sheets B-A, the filler sheets B-A in the front-rear direction in the stacking direction form a module having high structural stability, and the modules formed by the filler sheets B-A in the stacking direction are combined and adhered. Since the strength and stability of the single module are high, the difficulty of module assembly can be greatly reduced, and the efficiency of assembly of the filler module 1' from the modules of the filler sheets B-A can be improved.

[0180] In the drawings of the present embodiment, the right edge seal is not provided with the same structure as the left edge seal 215 for the convenience of assembly and processing. However, this does not limit the structure of the right edge seal, and the right edge seal can of course be provided with the same structure as the left edge seal 215.

[0181]

Third Embodiment

[0182] The filler module 1" of the third embodiment, which is a preferred embodiment of the present application, is as follows. Figure 13 、 14As shown, the difference between the filler module 1 of the above first embodiment lies in the configuration and assembly mode of the left upper path rectifier 230, the right upper path rectifier 240, the left lower path rectifier 330, and the right lower path rectifier 340 with the respective corresponding first upper end opening 210, the second upper end opening 220, the first lower end opening 310, and the second lower end opening 320.

[0183] In the present embodiment, the upper end edges of the left upper path rectifier 230 and the right upper path rectifier 240 are respectively lower than the first upper end opening 210 and the second upper end opening 220, i.e., the upper end edges of the left upper path rectifier 230 and the right upper path rectifier 240 are respectively located inside the first upper end opening 210 and the second upper end opening 220.

[0184] Likewise, the upper end edges of the left lower path rectifier 330 and the right lower path rectifier 340 are respectively higher than the first lower end opening 310 and the second lower end opening 320, i.e., the lower end edges of the left lower path rectifier 330 and the right lower path rectifier 340 are respectively located inside the first lower end opening 310 and the second lower end opening 320.

[0185] That is, in the present embodiment, the opening side end of the rectifier 230, 240, 330, 340 is respectively located inside the corresponding upper, lower end opening 210, 220, 310, 320 at a specified distance h. Figure 13 、 14 In the present embodiment, only the left upper path rectifier 230 is shown as an example, and the other rectifiers 240, 330, 340 can be similarly arranged.

[0186] When the filler pieces A, B are stacked, at the left upper segment guide portion 201, the left side upper end edges of the two are converged at the edge of the first upper end opening 210 due to the bias of the filler piece A to the rear side of the stacking direction and the bias of the filler piece B to the front side of the stacking direction.

[0187] Since the rectifier 230 embedded in the left upper segment guide portion 201 is located inside the first upper end opening 210, it avoids the upper end edges of the filler pieces 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 welding treatment by a heating clamp to form a welding track L.

[0188] In the first and second embodiments, the rectifier 230 is not retracted into the first upper end opening 210, and when the welding treatment is performed, only the folding of the rectifier 230 can be adapted due to the interference of the rectifier arranged in the folding manner at the end surface of the first upper end opening 210, forming an intermittent weld. As for the left side upper end edges of the filler pieces A-B, they can only be sealed by gluing after being converged.

[0189] In contrast, in the present embodiment, by retracting the rectifier fins into the first upper end opening 210, the left upper end edge of the filler piece A-B can be continuously pressure-welded using the avoidance area.

[0190] In this way, on the one hand, the connection strength of the left upper end edge of the filler piece A-B is improved, so that after the multi-layered filler pieces A, B are stacked, the overall strength of the filler module 1" can be significantly improved.

[0191] 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 piece A-B forming the first upper end opening 210 is in communication with the second flow path R2. By using a welded joint for the joint, the water tightness can be effectively improved, and the situation of delamination and water leakage due to aging over the years can be avoided.

[0192] 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 piece A and the filler piece B, respectively, the first flow path R1 can be minimized when used as a hot water spray flow path, and the left side can be sealed by welding without leakage.

[0193] As for the right side, since the first flow path R1 guides hot water from the left side by a portion of the width to the entire width of the heat exchange portion and then back to the left side by a portion of the width to flow out from the first lower end opening 310, it is difficult for the hot water to overflow from the right edge under the action of gravity, so the right edge sealing can be embedded, connected, bonded, spot-welded, etc. in a simple convex-concave joint manner.

[0194] Of course, the right edge sealing can also be performed in a manner corresponding to the left edge sealing without considering the slight increase in cost. Of course, by offsetting the right edge of the heat exchange portion 400 of the filler pieces A, B in the same direction as the left edge, a right edge sealing can be formed. Thus, the first flow path can be completely sealed.

[0195] In the present embodiment, as an example, only the configuration of the left upper rectifier fin 230 in the left upper section guide portion 201 and the first upper end opening 210 is described, and the same configuration can be adopted for the other second upper end opening 220, the first lower end opening 310, the second lower end opening 320, and the corresponding rectifier fins 240, 330, and 340. Thus, the strength of the filler module 1" as a whole can be improved, and in particular, the strength of the upper and lower end surfaces of the filler module 1" formed with the upper and lower end openings 210, 220, 310, 320 arranged side by side will be greatly improved. In this way, the firmness, reliability, and durability of the filler module 1" for transportation, operation and handling, installation work, and daily operation will be greatly improved.

[0196] [Fourth Embodiment]

[0197] 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 be formed with 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 over) can be in a state of being flipped over 180° with respect to the horizontal axis with respect to the filler sheet A, and thus, in the present embodiment, the description of the filler sheet B is described with respect to the position of the filler sheet A before being flipped over.

[0198] The filler sheet A is configured to have a left upper offset portion offset to the rear side on the left side of the upper end portion, a right upper offset portion offset to the front side on the right side of the upper end portion, a left lower offset portion offset to the rear side on the left side of the lower end portion, and a right lower offset portion offset to the front side on the right side of the lower end portion, and the adjacent filler sheet B can be arranged in a manner of being flipped over 180° about the horizontal axis of the body portion of the filler sheet A.

[0199] 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 the 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 forming the 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 respectively communicate with the 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-down direction, thereby forming the first flow path R1.

[0200] The left upper offset portion of the filler sheet A is aligned with the left lower offset portion of the filler sheet B located at 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 forming 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-down direction, thereby forming a second flow path R2.

[0201] Further, a left upper flow rectifying sheet 230 gradually increasing in width and gradually decreasing in thickness is provided between the left upper offset portion of the filler sheet A and the left lower offset portion of the filler sheet B from the first upper end opening 310 to the first heat exchange portion 401.

[0202] A left lower flow rectifying sheet 330 gradually increasing in width and gradually decreasing in thickness is provided between the left lower offset portion of the filler sheet A and the left upper offset portion of the filler sheet B from the first lower end opening 310 to the first heat exchange portion 401.

[0203] Similarly, a right upper flow rectifying sheet 240 gradually increasing in width and gradually decreasing in thickness is provided between the right upper offset portion of the filler sheet A and the right lower offset portion of the filler sheet B from the second upper end opening 220 to the second heat exchange portion 402.

[0204] A right lower flow rectifying sheet 340 gradually increasing in width and gradually decreasing in thickness is provided between the right lower offset portion of the filler sheet A and the right upper offset portion of the filler sheet B from the second lower end opening 320 to the second heat exchange portion 402.

[0205] 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 at the front side in the stacking direction.

[0206] The edge portion 215A of the filler sheet A is aligned with the edge portion 215B of the filler sheet B located at the front side in the stacking direction, and is welded and joined to form a left edge 215.

[0207] Thus, according to the present embodiment, the number of components can be further reduced, and when assembling the filler module using the filler sheets, it is only necessary to sequentially stack the filler sheet A without turning over and the filler sheet B turned over by 180°.

[0208]

Cooling tower 1

[0209] Figure 10 is a schematic view of a cooling tower made based on the filler module 1 of the present embodiment.

[0210] 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 by a plurality of filler modules 1 in the horizontal plane. A spraying part 104 is arranged above the filler layer 103, and the spraying part 104 sprays the hot water to be treated to each filler module 1 of the filler layer 103. The region between the spraying part 104 and the filler layer 103 is substantially vertically arranged with a partition plate 105 extending in the stacking direction of the filler module 1, 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 is a spraying space for spraying hot water, and the interval space 105b is a gas suction space for suctioning gas from bottom to top. The spraying space 105a and the gas suction space 105b are alternately arranged 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 communicated with the first upper end opening 210 and the second upper end opening 220.

[0211] Above the spraying part 104 is an air outlet layer 106, and above the air outlet layer 106 is an air outlet 108 provided with a fan 107. The fan 107 sucks air upward, so that the 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 then is discharged upward through the air outlet 108.

[0212] On the other hand, the hot water to be treated sprayed from the spraying part 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 recycled by a collecting device for recycling in the factory.

[0213] Working state one:

[0214] As described above, the cooling tower 10 is set to the winter working state. At this time, the hot water to be treated sprayed from the spraying part 104 is limited in the spraying space 105a and enters one of the two flow paths of the filler module 1. In this embodiment, since the partition plate 105 is arranged at the intersection position of the first upper end opening 210 and the second upper end opening 220 relative to the filler module 1, the first and second flow paths R1, R2 adjacent to each other between the two adjacent filler modules 1 are formed as water flow paths, and the outer flow paths R1, R2 are adjacent to the second and first flow paths on both sides, respectively, and are formed as air flow paths.

[0215] In the water flow path, the sprayed water flows into the packing module 1, is guided by the upper section guide 200, and is formed into a water film adhering to the two side walls in the stacking direction in the flat space of the heat exchange section 400 in the full width of the packing module 1. The two adjacent flow paths in the stacking direction serve as the air flow paths, and the walls of the packing pieces A and B are separated from the hot water in the water flow path to exchange heat.

[0216] When the cooling tower 10 is operated in winter, the air sucked into the air flow path from below the packing module 1 is dry cold air, which has a low temperature and a low water content. When the air exchanges heat with the hot water in the air flow path through the packing module 1, the heat exchange is completed in the independent flow path completely separated by the packing pieces A and B, so that the temperature of the air increases when it is discharged from above the packing module 1, but the water content does not change, i.e., dry hot air is formed.

[0217] On the other hand, because there is hot water sprayed from the spraying part 104 above in the water flow path, the air sucked by the fan 107 in the water flow path has a large resistance, so the air flow through the air flow path is very small, usually only one third. The air flowing through the air flow path forms hot saturated air, i.e., humid hot air.

[0218] The dry hot air flowing through the air flow path and the humid hot air flowing through the water flow path are mixed in the exhaust layer 106. Because 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 has a small amount of water vapor after being discharged to the atmosphere by the fan 107 and the exhaust port 108, which greatly reduces the amount of fog formed.

[0219] In the present embodiment, the spraying space 105a and the air induction space 105b can be flexibly switched by switching the spraying part 104, i.e., stopping spraying hot water on the spraying space 105a and spraying hot water on 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 operation of the cooling tower 10 can be ensured, and on the other hand, the flow path R1 or R2 of the packing module 1 connected to 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.

[0220] Working state two:

[0221] When operated in summer, the air induction space 105b can be sprayed with hot water in the same way as the spraying space 105a by adjusting the spraying part 104, so that the heat exchange efficiency of the cooling tower 10 can be improved as much as possible without fogging in summer.

[0222]

Cooling tower 20

[0223] In this embodiment, the filler module 1 is still used, but as the cooling tower 20, only the differences from the cooling tower 10 are described in detail, and the same structure is not described again.

[0224] The cooling tower 20 of this embodiment differs from the above-mentioned cooling tower 10 in that for each spray space 105a, a cover plate 109 along the stacking direction of the filler module 1 is further arranged substantially horizontally at the upper part of the partition wall 105. By arranging the cover plate 109, the partition wall 105 and the filler module 1, a plurality of interval spaces 205a, 205b are formed. In this embodiment, the cover plate 109 is only arranged in the spray space 205a for spraying hot water, and the cover plate 109 is not arranged for the air induction space 205b for air exhaust; of course, the cover plate 109 can be arranged for both the spray space 105a and the air induction space 205b, and the cover plate 109 can be arranged as a continuous plate or can be formed by a plurality of plates combined, and the cover plate 109 can be flipped or opened on one side or both sides of the partition wall 105 to form a detachable or openable mode, so that the spray space 205a and the air induction space 205b can be switched.

[0225] Working state one:

[0226] 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 above-mentioned cooling tower 10, except that the cover plate 109 is arranged above the spray space 205a, so that the spray space 205a will not function as air induction in principle, and only hot water passes through the flow path R1 or R2 of the filler module corresponding to the spray space 205a, so that in the air exhaust layer 106 of the cooling tower 20, only dry hot air from the air induction space 205b.

[0227] Therefore, the cooling tower 20 only has dry hot air drawn by the fan 107 and discharged from the air outlet 108, so that the moisture in the hot air discharged from the cooling tower 20 is reduced as much as possible, thereby further improving the fog dissipation capacity 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 less, which is more beneficial to water saving.

[0228] In the case where the openable (flat or open or detachable) cover plate 109 is arranged for 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 above-mentioned cooling tower 10, 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.

[0229] Of course, by opening only 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 substantially the same.

[0230] Working state two:

[0231] In the summer working state, by removing or opening the cover plate 109 above the spraying space 205a, the spraying part 104 is adjusted so that the air induction space 205b is also sprayed with hot water as the spraying space 205a, and the cooling tower 20 achieves the same working state as the cooling tower 10 described above to improve the heat exchange efficiency in summer.

[0232] In the cooling tower 20 of the present embodiment, the cover plate 109 provided above the interval spaces 205a, 205b is a flat plate, but is not limited thereto, and can be a plate extending from the partition plates 105 on both sides of the interval spaces 205a, 205b in the stacking direction of the packing modules 1 to the middle and lapping to close the interval spaces 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 spaces 205a, 205b can be closed, there is no limitation on the configuration of the cover plate 109.

[0233] In the above embodiment, the flow regulating piece 230 is provided in the left upper segment guide part 201 of the upper segment flow guiding part 200 of the first flow path R1 formed between the packing pieces B-A in the stacking direction of the packing modules 1.

[0234] Further, the flow regulating piece 240 is provided in the right upper segment guide part 202 of the upper segment flow guiding part 200 of the second flow path R2 formed between the packing pieces A-B in the stacking direction.

[0235] On the other hand, the flow regulating piece 330 is provided in the left lower segment guide part 301 of the lower segment flow guiding part 300 of the first flow path R1 formed between the packing pieces B-A in the stacking direction.

[0236] Further, the flow regulating piece 340 is provided in the right upper segment guide part 202 of the lower segment flow guiding part 300 of the second flow path R2 formed between the packing pieces A-B in the stacking direction.

[0237] 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 fact, the rectifier 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 sheet B-A downward to the left side edge of the upper section guide portion 200, then rightward along the lower end portion line of the side upper section guide portion 200 to the right side edge of the upper section guide portion 200, and then again upward to the substantially middle portion of the upper edge of the filler sheet A(B). For the filler sheet A, the substantially right-angled trapezoidal region is biased to the rear side, and for the filler sheet B, the substantially right-angled trapezoidal region is biased to the front side, so that in the stacking direction, the front side filler sheet A and the rear side filler sheet B, i.e., the filler sheet A-B, are in close contact at the periphery of the first upper end opening 210, and the open width of the first upper end opening 210 in the stacking direction between the front side filler sheet B and the rear side filler sheet A, i.e., the filler sheet B-A, is 2d. That is, in the substantially right-angled 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 portion connected to the heat exchange portion 400 is the interval d between the filler sheets A and B, thereby forming the space of the left upper section guide portion 201.

[0238] The cross section of the rectifier fin 230 in the horizontal direction is a meandering shape extending perpendicularly to the stacking direction. The meandering amplitude of the upper portion near the first upper end opening 210 is large, and the meandering span is small. As the rectifier fin 230 extends from the upper portion to the heat exchange portion 400, the meandering amplitude gradually decreases, and the meandering span gradually increases, to fill the space of the left upper section guide portion 201. By making the rectifier 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 thick upper end in the stacking direction and a small width in the horizontal direction, and a thin lower end with a large width, so that the hot water flowing in from the first upper end opening 210, which is approximately half the width of the filler module 1, can be uniformly guided to the heat exchange portion 400, which is approximately the full width of the filler module 1. The cross-sectional area of the guide flow path changes as little as possible from the upper portion to the lower portion, whether it is a single guide flow path or the entire guide flow path, to reduce the resistance of the fluid. Good passage efficiency is achieved for both the hot water sprayed from above and the air drawn upward from below.

[0239] The rectifier fin 240 located in the space of the right upper section guide portion 202 is also similarly configured, except that the position is rotationally symmetric to the rectifier fin 240 in the horizontal direction.

[0240] For the rectifying fins 330, 340, as with the left upper guide portion 201 and the right upper guide portion 202 of the upper guide portion 200, the left lower guide portion 301 formed by offsetting the area of the inverted right-angled trapezoidal region of the filler piece B-A at the lower guide portion 300 to the outside of the stacking direction, and the right lower guide portion 302 formed by offsetting the area of the inverted right-angled trapezoidal region of the filler piece A-B at the lower guide portion 300 to the outside of the stacking direction, are respectively provided in. The rectifying fins 330, 340 form a plurality of flow paths in the left lower guide portion 301 and the right lower guide portion 302, respectively, with the upper end having a small thickness in the stacking direction and a large width in the horizontal direction, and the lower end having 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 portion 400 of the filler module 1 to the first and second lower end openings 310, 320 of approximately half the width.

[0241] 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 in the process of extending from the bottom to the top towards the heat exchange portion 400, the bending amplitude gradually decreases and the bending span gradually increases.

[0242] For the rectifying fins 330 located in the space of the left lower guide portion 301 and the rectifying fins 340 located in the space of the right lower guide portion 302, as with the left upper guide portion 201 and the right upper guide portion 202, they are rotationally symmetrical in the horizontal direction.

[0243] Therefore, in the case where the first and second upper end openings 210, 220 and the first and second lower end openings 310, 320 are each approximately half the width of the filler module 1, if the vertical direction length of the upper and lower guide portions 200, 300 is the same, the left upper guide portion 201, the right upper guide portion 202, the left lower guide portion 301, and the right lower guide portion 302 can form a rotationally symmetrical structure, and thus the rectifying fins 230, 240, 330, 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, when being manufactured, thereby not only significantly reducing the mold cost and the component production cost for manufacturing the filler module 1, but also making the assembly convenient without considering the model difference of the rectifying fins, thereby greatly reducing the overall production cost of the filler module 1.

[0244] 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.

[0245] [5th Embodiment]

[0246] 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

[0247] 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.

[0248] 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 is located at the middle portion in the upper end width direction of the filler module 1000, to the first heat exchange portion 401, which is substantially the entire width of the filler module 1000.

[0249] 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 are located 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 is substantially the entire width of the filler module 1000.

[0250] ​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.

[0251] 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.

[0252] In the present embodiment, by biasing the filler sheet 1000B and the filler sheet 1000A from the upper end opening G toward the portion of the first heat exchange portion 401 at the upper section guide portion 200, the first biasing portions 1100B, 1100A are formed, the distance between the filler sheet 1000B and the filler sheet 1000A is increased, and thus the first upper end opening portion 1100 of the first upper section guide portion 200G is formed. Further, for the filler sheet 1000A and the filler sheet 1000B at the upper section guide portion 200, the filler sheet 1000A and the filler sheet 1000B are brought together at the portion due to the formation of the first biasing portions 1100A, 1100B.

[0253] 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 toward the portion of the second heat exchange portion 402 at the upper section guide portion 200, the second biasing portions 1200A, 1200B are formed, the distance between the filler sheet 1000A and the filler sheet 1000B is increased, and thus the second upper end opening portion 1200 of the second upper section guide portion 200W is formed. Further, for the filler sheet 1000B and the filler sheet 1000A at the upper section guide portion 200, the filler sheet 1000B and the filler sheet 1000A are brought together at the portion due to the formation of the second biasing portions 1200B, 1200A.

[0254] 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 entire 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 entire 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.

[0255] 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.

[0256] 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.

[0257] 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 entire 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.

[0258] 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 entire 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.

[0259] 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 triangle 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.

[0260] Accordingly, at the positions of the first and second rectifying sheets 1300G, 1300W corresponding to the first and second upper end openings 1100, 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 triangles 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.

[0261] Further, in the present embodiment, in addition to forming the first and second upper end openings 1100, 1200 by providing offset portions in the first and second upper section guide portions 200G, 200W, respectively, and providing the first and second rectifying sheets 1300G, 1300W, the first and second lower end guide portions 400G, 400W can be formed by providing the same offset portions, and the third and fourth rectifying sheets 1300G', 1300W' can be provided. Further, the same first and second lower end openings are formed.

[0262] 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.

[0263] (Usage Example 1)

[0264] 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

[0265] ​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 partitioning the air flow path and the spray water flow path, and the sealing portion between the filler module 1000, are both located inside 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.

[0266] 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.

[0267] 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.

[0268] 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.

[0269] 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 partition of the partition plate 2005, further avoids obtaining moisture from the spray portion.

[0270] 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.

[0271] (Use example 2)

[0272] 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 taken in below the filler module 1000, after the cold air is discharged above the filler module, only a small amount of water vapor is mixed with the heat-exchanged cold air above the partition plate 2005.

[0273] Because the temperature of the heat-exchanged cold air increases, 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 heat-exchanged air with significantly reduced saturation can be effectively used to absorb the moisture released from the spray part. Except for the case where the winter temperature is very low, the cooling tower 2100 of this use example 2 can also effectively achieve the effect of eliminating mist.

[0274] 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.

[0275] 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, which cannot guarantee the uniformity of the air resistance of the entire cooling tower, and thus will inevitably affect the uniformity of the heat exchange efficiency of the packing modules in the entire cooling tower.

[0276] The packing module 1000 of the present embodiment can solve the above problems.

[0277] (Usage Example 3)

[0278] 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.

[0279] 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.

[0280] In the cooling tower 3000, unlike the previous ones, a specified installation interval 3999 of 300-600 mm is arranged between each packing module 1000, and a closing plate 3998 is preferably arranged on the installation seat surface at the interval between the packing modules 1000. If the closing plate 3998 is not arranged, 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.

[0281] At this time, contrary 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 spray water.

[0282] 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.

[0283] 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. However, 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.

[0284] 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.

[0285] 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.

[0286] (Use Case 4)

[0287] Figure 30 is a schematic diagram of Use Case 4. In the present use case, similar to Use Case 3, an interval is arranged between the packing modules 1000 in the lateral direction, but a normal packing module F is further arranged in the interval.

[0288] As the general filler module F, it can be any filler module in existence. For example, it is the filler module F formed by simply laminating a plurality of filler sheets, which is the most widely used filler module F so far, and in this case, there is no flow path divided in the filler module F. For each thin sheet-like heat exchange space formed by two adjacent filler sheets in the lamination direction, hot water is sprinkled from the upper end opening, 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 are directly contacted to exchange heat.

[0289] As shown above, in the present use example, the second flow path 1000W is preferably the flow path for sprinkling hot water, and the first flow path 1000G is the air flow path. Thus, 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 W1, 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 on the other hand, the hot water sprinkled into the filler module F directly exchanges heat with the air drawn from the lower end of the filler module F in the filler module.

[0290] Thus, the air discharged upward from the first upper end opening G of the filler module 1000 forms hot air with low saturation, and the hot air discharged from the upper end of the filler module F becomes saturated hot air.

[0291] On the other hand, due to the provision of the second upper end openings W1, W2, the air resistance in the second flow path 1000W is very large, so in practice, the amount of air discharged upward from the second upper end opening W of the filler module 1000 is very small, and the amount of air passing through the filler module F is very small.

[0292] 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 a very small amount of saturated hot air discharged from the second upper end openings W1 / W2 of the filler module 1000 are mixed above the filler module. Thus, the unsaturated hot air is effectively utilized, the saturation of the mixed air is reduced, and the heat exchange efficiency of the cooling tower is greatly improved under the premise of ensuring sufficient fog elimination effect.

[0293] 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.

[0294] 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.

[0295] 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.

[0296] 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.

[0297] 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.

[0298] 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.

[0299] 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.

[0300] The flow straighteners 1300G, 1300W are located in the upper section guide portion of the filler module 1000, and when guiding hot water to flow in, the sprayed hot water needs to be guided 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 caused 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.

[0301]

Filler assembly 5100

[0302] 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.

[0303] 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.

[0304] 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, and the packing assembly 5100 is installed into the cooling tower from the left side in Figure 34 , and the packing assembly 5100' is installed into the cooling tower from the right side in Figure 34 . In the above manner, when building the cooling tower, 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.

[0305] In some embodiments, the packing frame 5100 can be formed by welding, screw connection, or other methods using profiles such as square tubes and angle iron. The components forming the packing frame 5100 can be located at various corners of the packing module 1000. To improve the strength of the packing frame 5100, at least one horizontal, vertical, or inclined tie rod 5111 can also be provided.

[0306] like Figure 31 and Figure 32 As shown, the filler assembly 5100 may further include an upper frame 5120, which is fixed to the upper side of the filler frame 5110. The upper frame 5120 can be used as a support structure for the spray system 5200, and the spray pipes 5210 of the spray system can be fixed to the top of the upper frame 5120, and the nozzles 5220 can be installed in appropriate positions.

[0307] In addition, the aforementioned upper frame 5120 can have a split structure, that is, multiple upper frame 5120 splits are assembled to form an upper frame 5120, and the upper frame 5120 is installed on the upper side of the packing frame 5110, which reduces the weight of a single split and facilitates transportation and assembly.

[0308] like Figure 33 As shown, by setting the above-mentioned packing frame 5110 and upper frame 5120, support can be provided for the installation of partition 2005 and partition 2005', without having to build a crossbeam in the cooling tower, which improves the convenience of installation and the sealing performance of partition 2005 and partition 2005'.

[0309]

Packaging Assembly 6100

[0310] In the above implementation, the entire packing assembly needs to be assembled in the factory and then transported to the construction site for installation in the cooling tower by hoisting as a whole. This results in the packing assembly 5100 being large in size, making construction, transportation and installation inconvenient.

[0311] However, if the above frame 5110 is simply divided into segments, other problems will arise: it is not easy to form an effective seal between the packing segments, the flow path between two adjacent packing segments is blocked or blocked, and cannot be effectively utilized; the integral frame also has an adverse effect on the assembly of the packing sheets.

[0312] 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 35Two filler modules 1000a, 1000b are shown in FIG. 1. The upper section of each of the filler modules 1000a, 1000b forms a first upper end opening 1100 and a second upper end opening 1200. Further, a first upper end opening G and second upper end openings W1, W2 on both sides of the first upper end opening G in the width direction are formed at the upper end edges of the first upper end opening 1100 and the second upper end opening 1200. A first upper separation zone E1 is formed between the first upper end opening G and the second upper end opening W1, and a second upper separation zone E2 is formed between the first upper end opening G and the second upper end opening W2. Due to the folding of the filler sheet, the first upper separation zone E1 and the second upper separation zone E2 often have a tortuous structure, which causes certain difficulties in effectively separating the first upper end opening G and the second upper end openings W1, W2.

[0313] In addition, a first lower end opening G' corresponding to the first upper end opening G, second lower end openings W1', W2' corresponding to the second upper end openings W1, W2, a first lower separation zone E1' formed between the first lower end opening G' and the second lower end opening W1', and a second lower separation zone E2' formed between the first lower end opening G' and the second lower end opening W2' can also be formed at the lower end face of the filler modules 1000a, 1000b.

[0314] Figure 35 The two filler modules 1000a, 1000b are also shown in the stacking direction. When they are brought together, it is not easy to form an effective seal at the connecting end face. For example, a sealing material can be filled between the end faces of the two filler modules 1000a, 1000b that are brought close to each other, but the filler sheet is a thin plastic sheet, and its strength is not sufficient to apply sufficient extrusion pressure to the sealing material, often resulting in sealing failure. Moreover, the above-mentioned sealing method also causes the flow path at the connection of the filler modules 1000a, 1000b to be blocked and fail.

[0315] To solve the above technical problems, the present application provides a filler assembly 6100 that is easy to assemble, seal, transport and install, and can effectively utilize the flow path at the connection of two adjacent filler assemblies 6100 in the stacking direction of the filler sheet, thereby increasing the heat exchange area.

[0316] Figure 36 is a front view of a filler assembly 6100 formed by installing the filler module of the fifth embodiment of the present application in another structure of a filler frame. Figure 37 is Figure 36 is a partial enlarged view A in FIG. 1;

[0317] As 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.

[0318] 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 adapted to cover the corresponding partition areas.

[0319] The upper end of the tensioning assembly 6130 is connected to the upper bracket 6120, and the lower end is connected to the lower bracket 6110, 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 cause a certain amount of deformation of the sealing strip 6142, 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 implemented by a steel wire rope.

[0320] As shown in Figure 37 The upper bracket 6120 includes a first upper support portion 6121 corresponding to the first upper partition area E1, and a second upper support portion 6122 corresponding to the second upper partition area E2. The extension directions of the first and second upper support portions 6121, 6122 are the same as the stacking direction of the filler sheets. The lengths of the first and second upper support portions 6121, 6122 are substantially the same as the thickness of the filler module 1000 in the stacking direction.

[0321] The lower bracket 6110 includes a first lower support portion 6111 corresponding to the first lower partition area E1', and a second lower support portion 6112 corresponding to the second lower partition area E2'. The extension directions of the first and second lower support portions 6111, 6112 are the same as the stacking direction of the filler sheets. The lengths of the first and second lower support portions 6111, 6112 are substantially the same as the thickness of the filler module 1000 in the stacking direction.

[0322] Figure 38 is a schematic view of the outer shape of the filler assembly of the present embodiment;

[0323] 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.

[0324] 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.

[0325] 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.

[0326] 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.

[0327] 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. Preferably, 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 205b, thereby avoiding icing.

[0328] 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.

[0329] Figure 39 is an assembly structure schematic view of a plurality of filler assemblies 6100, which shows the top structure of the filler assembly 6100;

[0330] Figure 40 is a schematic view of the connecting structure of two filler assemblies 6100a, 6100b adjacent in the stacking direction; Figure 41 is a schematic view of the assembled structure of a plurality of filler assemblies 6100, which shows the bottom structure of the filler assemblies.

[0331] As shown in Figures 38 to 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, the filler assemblies 6100a, 6100b, 6100c, 6100d are connected in sequence in the stacking direction, which improves the convenience of transportation and installation.

[0332] 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, thereby playing a sealing role at the connection (corresponding to the first upper partition area E1). Preferably, a bolt assembly can be provided at the connection end face to connect and compress the sealing gasket 6160.

[0333] 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, thereby playing a sealing role at the connection (corresponding to the second upper partition area E2).

[0334] For the connection between the filler assembly 6100a and the filler assembly 6100b, a horizontal tie 6150 can be used as shown in the figure, one end of the horizontal tie 6150 is connected with the filler assembly 6100a and the other end is connected with the filler assembly 6100b, thereby achieving reliable connection between the two. The position of the above-mentioned horizontal tie 6150 has multiple choices, for example, the upper cross beam 6123a of the filler assembly 6100a and the upper cross beam 6123b of the filler assembly 6100b can be tightened. 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.

[0335] 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 blocked, and the first upper partition area E1 and the second upper partition area E2 at the connection are effectively sealed, which can ensure the effective operation of the flow path at the connection by means of gluing and the like, thereby improving the overall heat exchange area of the cooling tower.

[0336] 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 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.

[0337] In addition, the filler module 1000 in the embodiment can also be a filler module 1, which has a first upper end opening 210 and a second upper end opening 220 at the upper end, and an upper separation zone between the first upper end opening 210 and the second upper end opening 220. The filler module 1 has a first lower end opening 310 and a second lower end opening 320 at the lower end, and a lower separation zone between the first lower end opening 310 and the second lower end opening 320. When the filler assembly is formed, the number and position of the upper support parts in the upper bracket and the upper separation zone need to be adjusted accordingly, and the number and position of the lower support parts in the lower bracket and the lower separation zone need to be adjusted accordingly, and the protection scope of the present application covers the above technical solutions.

Cooling tower 7000

[0339] In a cooling tower with a double-flow filler module, some areas inside the cooling tower, especially the areas close to the tower wall, are prone to icing in cold winter weather. To solve this technical problem, the present embodiment provides a cooling tower 7000, which will be described in detail below.

[0340] Figure 42 is a top view of a cooling tower composed of a filler assembly.

[0341] As Figure 42 shown, in the left-right direction identified by the coordinate system, the inside of the cooling tower 7000 is horizontally alternately provided with a spraying space 205a and an air induction space 205b. The spraying part 7300 includes a water supply pipeline 7310, a first spraying manifold 7320, and a second spraying manifold 7330. The first spraying manifold 7320 is arranged in the spraying space 205a, and the second spraying manifold 7330 is arranged in the air induction space 205b. In the non-mist elimination mode, both the first spraying manifold 7320 in the spraying space 205a and the second spraying manifold 7330 in the air induction space 205b spray hot water to maximize the heat exchange efficiency; in the mist elimination mode, only the first spraying manifold 7320 in the spraying space 205a sprays hot water, and only air flows through the air induction space 205b.

[0342] At the two ends of the inside of the cooling tower in the front-rear direction (i.e., the direction of stacking of the filler sheets), a first end isolation zone 7210 and a second end isolation zone 7220 are respectively arranged. As Figure 42As shown, the internal dimension of the cooling tower 7000 in the front-rear direction is M, while the length of the spraying space 205a is f, f < M, i.e. space is left for the first and second end isolation zones 7210, 7220. The first end isolation zone 7210 is provided with a first end branch pipe 7340 extending in the left-right direction, which is connected to the second spraying pipe manifold 7330 and only works in the non-fog mode. The second end isolation zone 7220 is provided with a second end branch pipe 7350 extending in the left-right direction, which is connected to the second spraying pipe manifold 7330 and also only works in the non-fog mode. By providing the first and second end isolation zones 7210, 7220, a buffer area is established between the tower wall of the cooling tower 7000 and the spraying space 205a, so that even if water droplets leak or splash out of the spraying space 205a, they will fall into the first and second end isolation zones 7210, 7220 and will not form a wall flow on the inner surface of the tower wall of the cooling tower to freeze.

[0343] Figure 43 is Figure 42 is a front view of the cooling tower; Figure 44 is a partial perspective view of the cooling tower formed by the packing assembly and the partition plate.

[0344] As Figure 43 and Figure 44 shown, to form the first and second end isolation zones 7210, 7220, end partition plates 2006 are provided at the front-rear direction ends of the partition plate 2005, which can extend in the left-right direction, for example. The partition plate 2005 and the end partition plates 2006 limit the spraying space 205a to the space enclosed thereby, while the air induction space 205b is formed outside the partition plate 2005 and the end partition plates 2006.

[0345] In the first and second end isolation zones 7210, 7220, omnidirectional ordinary packing modules F can be provided, which can meet the heat exchange requirements in the non-fog mode and have low manufacturing cost. In addition, as Figure 43 shown, packing modules F can also be installed between the packing assemblies 6100 (in the left-right direction).

[0346] The difference between the present embodiment and the above-described use example 4 is that, in the present embodiment, in the fog mode, the flow path between the first upper end opening and the first lower end opening of the packing module 1000 is used as the water flow path, while the flow path between the second upper end opening and the second lower end opening, and the flow path formed in the packing module F are used as the air flow path.

[0347] The filler module and the cooling tower with the filler module of the preferred embodiments of the present application 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.
