[0085] Hereinafter, the preferred embodiment of the present application will be described in detail with reference to the accompanying drawings.

[0086] [First Embodiment]

[0087] Hereinafter, the filler module 1 of the first embodiment of the present application will be described in detail.

[0088] [Filler Module 1]

[0089] In the present embodiment, the filler module 1 includes filler pieces A and filler pieces 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 pieces A and B in the filler module 1.

[0090] The upper section and the lower section of the filler module 1 form the upper section guide portion 200 and the lower section guide portion 300, respectively, and the middle section forms the heat exchange portion 400.

[0091] [Upper Section Guide Portion 200]

[0092] The guide port is formed by the upper end portions of the rectangular filler pieces A and B alternately arranged on the upper end of the upper section guide portion 200, specifically as follows.

[0093] The upper end portion of the filler piece A on the side perpendicular to the laminating direction (left side in the figure) is biased toward the side of the laminating direction (back side in the figure), and the upper end portion of the filler piece B is biased toward the opposite side (front side in the figure), so that the upper end portions of the filler pieces A-B on the left side are adhered to each other in the laminating direction from the front side to the back side in the figure, and the upper end portions of the filler pieces B-A on the left side are open to each other to form the first upper end opening 210. For the filler module 1, a plurality of first upper end openings 210 are arranged side by side in the laminating direction. Thus, the first upper end opening 210 communicates with the first flow path Rl formed between the filler pieces B-A.

[0094] The upper end portion of the filler sheet A on the other side (right side in the drawing) in the stacking direction is offset to the other side (front side in the drawing) in the stacking direction, and the upper end portion of the filler sheet B is offset to the opposite side (rear side in the drawing) in the stacking direction, so that the upper end portions of the filler sheet B-A on the right side are in contact with each other and the upper end portions of the filler sheet A-B on the right side are open to each other as the second upper end opening 220 in the stacking direction from the front side to the rear side in the drawing, and a plurality of second upper end openings 220 are arranged side by side in the stacking direction for the filler module 1. Thus, the first upper end opening 220 communicates with the first flow path R2 formed between the filler sheets A-B.

[0095] In the upper section guide portion 200, the left upper path rectification sheet 230 is embedded in the first flow path R1 between the first upper end opening 210 formed by the filler sheet B-A and the heat exchange portion 400 surrounded by the filler sheet B-A. The upper end of the left upper path rectification sheet 230 matches the width of the first upper end opening 210, and the width gradually increases from the top to the bottom, and the lower end corresponds to the width of the heat exchange portion 400 (the first heat exchange portion 401 of the first flow path).

[0096] In the present embodiment, the left upper path rectification sheet 230 has a meandering shape in the lateral cross section perpendicular to the stacking direction, and the both sides of the meandering shape in the stacking direction, that is, the back side abuts against the front surface of the filler sheet A holding it, and the front side abuts against the rear surface of the filler sheet B holding it. Thus, in the first flow path R1 formed between the first upper end opening 210 and the heat exchange portion 400, a guide portion that guides from the width of the first upper end opening 210 to the full width of the heat exchange portion 400 of substantially the width of the filler sheets A, B is formed.

[0097] In the upper section guide portion 200, the right upper path rectification sheet 240 is embedded in the second flow path R2 between the second upper end opening 220 formed by the filler sheets A-B and the heat exchange portion 400 surrounded by the filler sheets A-B. The upper end of the right upper path rectification sheet 240 matches the width of the second upper end opening 220, and the width gradually increases from the top to the bottom, and the lower end corresponds to the width of the heat exchange portion 400 (the first heat exchange portion 402 of the second flow path).

[0098] In the present embodiment, the right upper path rectification sheet 240 has a meandering shape in the lateral cross section perpendicular to the stacking direction, and the both sides of the meandering shape in the stacking direction, that is, the back side abuts against the front surface of the filler sheet B holding it, and the front side abuts against the rear surface of the filler sheet A holding it. Thus, in the second flow path R2 formed between the second upper end opening 220 and the heat exchange portion 400, a guide portion that guides from the width of the second upper end opening 220 to the full width of the heat exchange portion 400 of substantially the width of the filler sheets A, B is formed.

[0099]

Lower section guide portion 300

[0100] The lower end of the lower section guide portion 300 is formed with guide openings by alternately arranging the lower end portions of the filler pieces A and B, as follows.

[0101] The lower end portions of the filler pieces A are biased toward the side of the stacking direction (the back side in the drawing) on the side perpendicular to the stacking direction (the left side in the drawing), and the lower end portions of the filler pieces B are biased toward the opposite side (the front side in the drawing) on the side perpendicular to the stacking direction (the right side in the drawing), thereby forming, in the stacking direction from the front side to the back side in the drawing, the lower end portions of the filler pieces A-B on the left side to be in contact with each other, and the lower end portions of the filler pieces B-A on the left side to be open to each other as a first lower end opening 310. Thus, the first lower end opening 310 communicates with the first flow path Rl formed between the filler pieces B-A.

[0102] The lower end portions of the filler pieces A are biased toward the side of the stacking direction (the back side in the drawing) on the side perpendicular to the stacking direction (the left side in the drawing), and the lower end portions of the filler pieces B are biased toward the opposite side (the front side in the drawing) on the side perpendicular to the stacking direction (the right side in the drawing), thereby forming, in the stacking direction from the front side to the back side in the drawing, the lower end portions of the filler pieces A-B on the left side to be in contact with each other, and the lower end portions of the filler pieces B-A on the left side to be open to each other as a first lower end opening 310. Thus, the first lower end opening 310 communicates with the first flow path Rl formed between the filler pieces B-A.

[0103] In the lower section guide portion 300, a left lower path rectifying piece 330 is embedded in the first flow path Rl between the first lower end opening 310 formed by the filler pieces B-A and the heat exchange portion 400 surrounded by the filler pieces B-A. The lower end of the left lower path rectifying piece 330 matches the width of the first lower end opening 310, and the width gradually increases from the lower end to the upper end, which corresponds to the width of the heat exchange portion 400.

[0104] In the present embodiment, the left lower path rectifying piece 330 has a meandering shape in a lateral cross section perpendicular to the stacking direction, with the back side of the meandering shape abutting against the front surface of the filler piece A and the front side abutting against the back surface of the filler piece B. Thus, in the first flow path Rl formed between the first lower end opening 310 and the heat exchange portion 400, which is approximately an inverted right-angled trapezoid, a guide portion is formed that guides the width from the first lower end opening 310 to the full width of the heat exchange portion 400, which is approximately the width of the filler pieces A and B.

[0105] In the lower section guide portion 300, a right lower path rectifying piece 340 is embedded in the second flow path R2 between the second lower end opening 320 formed by the filler pieces A-B and the heat exchange portion 400 surrounded by the filler pieces A-B. The lower end of the right lower path rectifying piece 340 matches the width of the second lower end opening 320, and the width gradually increases from the upper end to the lower end, which corresponds to the width of the heat exchange portion 400.

[0106] In the present embodiment, the right lower rectification fin 340 has a meandering shape in a lateral cross section perpendicular to the stacking direction, with the meandering back side abutting the front surface of the filler piece B and the front side abutting the rear surface of the filler piece A. Thus, a guide portion that guides from the width of the second lower end opening 320 to the full width of the heat exchange portion 400, which is approximately the width of the filler pieces A and B, is formed in the second flow path R2, which is approximately an inverted right-angled trapezoid, formed between the second lower end opening 320 and the heat exchange portion 400.

[0107] By alternately stacking the filler piece A and the filler piece B to form the filler module 1, the first flow path Rl and the second flow path R2, which are alternately stacked and isolated from each other, are formed in the filler module 1. Hereinafter, the configuration of the first flow path Rl and the second flow path R2 will be described in detail.

[0108] [First flow path Rl unit]

[0109] 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 first flow path Rl is formed between an adjacent filler piece B and a filler piece A located at the rear side of the filler piece B, i.e., a filler piece B-A.

[0110] As shown in the drawing, the first flow path Rl includes, from top to bottom, the first upper end opening 210 located at the left upper end of the filler module 1, the left upper segment guide portion 201 of the upper segment guide portion 200 filled and supported between the filler pieces B and A by the left upper rectification fin 230, the first heat exchange portion 401 formed as a flat cavity between the filler pieces B-A at the heat exchange portion 400 in the stacking direction, the left lower segment guide portion 301 of the lower segment guide portion 300 filled and supported between the filler pieces B and A by the left lower rectification fin 330, and the first lower end opening 310 located at the left lower end of the filler module 1.

[0111] Thus, in the present embodiment, one unit of the first flow path Rl formed as a flat cavity is formed between an adjacent filler piece B and a filler piece A, with the first upper end opening 210 as the upper end opening and the first lower end opening 310 as the lower end opening located on the same side perpendicular to the stacking direction.

[0112] [Second flow path R2 unit]

[0113] 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 an adjacent filler piece A and a filler piece B located at the rear side of the filler piece A, i.e., a filler piece A-B.

[0114] As shown in the figure, the second flow path R2 includes, from top to bottom, a second upper end opening 220 on the right side of the upper end of the packing module 1, a right upper segment guide portion 202 on the upper segment guide portion 200 filled and supported by the right upper path rectification fin 240 between the packing fins A and B, a second heat exchange portion 402 in the form of a flat cavity formed between the packing fins A and B at the heat exchange portion 400 in the stacking direction, a right lower segment guide portion 302 on the lower segment guide portion 300 filled and supported by the right lower path rectification fin 340 between the packing fins A and B, and a second lower end opening 320 on the right side of the lower end of the packing module 1.

[0115] Thus, in the present embodiment, one unit of the first flow path Rl in the form of a flat cavity is formed between the adjacent packing fin A and packing fin B, and the second upper end opening 220 as the upper end opening thereof and the second lower end opening 320 as the lower end thereof are located on the same side perpendicular to the stacking direction.

[0116] [Heat exchange portion 400]

[0117] The first heat exchange portion 401 and the second heat exchange portion 402 are alternately stacked, and the heat exchange portion 400 in which the first flow path Rl and the second flow path R2 are alternately stacked and spaced apart from each other for heat exchange is formed.

[0118] [Upper and lower end openings of flow path]

[0119] As described above, in the stacking direction of the packing fins A and B, the first flow path Rl and the second flow path R2 in the form of a flat cavity are formed between the packing fin B-A and the packing fin A-B, respectively, and thus the first flow path Rl and the second flow path R2 are alternately stacked. Thus, for the packing module 1, the first and second upper end openings 210 and 220 are formed on the upper end edge in parallel to the stacking direction.

[0120] 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 portion of the packing fin A is biased toward the back side in the figure and the left upper end portion of the packing fin B is biased toward the opposite front side in the figure, the left upper end portions of the packing fin A-B are in contact with each other, and the left upper end portions of the packing fin B-A are open to each other. Thus, a strip-shaped opening in which the left upper end portions of the packing fin B-A are open to each other is formed, and the left upper end portions of the packing fin A-B in contact with each other are arranged in parallel in the stacking direction to form the complete first upper end opening 210. Without considering the thickness of the packing fins, the entire region on the upper end of the packing module 1 on the side (left side in the figure) perpendicular to the stacking direction forms the open first upper end opening 210.

[0121] Likewise, the second upper end opening 220 is formed on the right side, and the right side upper end portions of the filler pieces B are biased toward the back side in the drawing, and the right side upper end portions of the filler pieces A are biased toward the opposite front side in the drawing, in contrast to the first upper end opening 210, so that the right side upper end portions of the filler pieces B-A are in contact with each other, and the right side upper end portions of the filler pieces A-B are open to each other. Thus, the strip-shaped openings in which the left side lower end portions of the filler pieces B-A are open to each other are arranged in parallel in the stacking direction via the contacting left side lower end portions of the filler pieces A-B, and the complete first lower end opening 310 is formed. The entire area corresponding to the side (left side in the drawing) of the filler module 1 at the lower end perpendicular to the stacking direction forms the open first lower end opening 310, without considering the thickness of the filler pieces.

[0122] On the other hand, the first and second upper end openings 210, 220 are formed on the lower end edges in parallel to the stacking direction.

[0123] In the present embodiment, as shown in the drawing, the first lower end opening 310 is formed on the left side, and the left side lower end portions of the filler pieces A are biased toward the back side in the drawing, and the left side lower end portions of the filler pieces B are biased toward the opposite front side in the drawing, so that the left side lower end portions of the filler pieces A-B are in contact with each other, and the left side lower end portions of the filler pieces B-A are open to each other. Thus, the strip-shaped openings in which the left side lower end portions of the filler pieces B-A are open to each other are arranged in parallel in the stacking direction via the contacting left side lower end portions of the filler pieces A-B, and the complete first lower end opening 310 is formed. The entire area corresponding to the side (left side in the drawing) of the filler module 1 at the lower end perpendicular to the stacking direction forms the open first lower end opening 310, without considering the thickness of the filler pieces.

[0124] Likewise, the second lower end opening 320 is formed on the right side, and the right side lower end portions of the filler pieces B are biased toward the back side in the drawing, and the right side lower end portions of the filler pieces A are biased toward the opposite front side in the drawing, in contrast to the first lower end opening 310, so that the right side lower end portions of the filler pieces B-A are in contact with each other, and the right side lower end portions of the filler pieces A-B are open to each other. Thus, the strip-shaped openings in which the right side lower end portions of the filler pieces A-B are open to each other are arranged in parallel in the stacking direction via the contacting right side lower end portions of the filler pieces B-A, and the complete second lower end opening 320 is formed. The entire area corresponding to the other side (right side in the drawing) of the filler module 1 at the lower end perpendicular to the stacking direction forms the open second lower end opening 320, without considering the thickness of the filler pieces.

[0125]

Openings of flow paths

[0126] The first flow path Rl is further described in detail in the direction from the top to the bottom.

[0127] As described above, the first flow path R1 at the upper end of the packing module 1 corresponds to the formation of the first upper end opening 210 in the entire region on the left side perpendicular to the stacking direction, and at the first upper end opening 210, the portion where the left side upper end portions of the packing pieces A-B are adhered to each other is divided into a plurality of units. In the left upper section guide portion 201, after passing downward through the portion where the left side upper end portions of the packing pieces A-B are adhered to each other, the units of the first flow path R1 are separated from each other in the stacking direction, and on the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases in the direction perpendicular to the stacking direction to approximately 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 first heat exchange portion 401 of the flat heat exchange space defined by the packing pieces B-A entering the heat exchange portion 400 from the upper section guide portion 200.

[0128] In the continuation of the heat exchange portion 400 downward to the lower section guide portion 300, in contrast to the case in the upper section guide portion 200, the units of the first flow path R1 downward from the flat shape of approximately the width of the packing pieces A, B, on the one hand, the size gradually increases in the stacking direction, and on the other hand, the size gradually decreases in the direction perpendicular to the stacking direction to the width of the second lower end opening 220, that is, the thickness increases and the width decreases, and in the left lower section guide portion 301, the portion where the left side lower end portions of the packing pieces A-B are adhered to each other converges to reach the first lower end opening 310.

[0129] Thus, in the first flow path R1, the entire section flow path from the first upper end opening 210, through the upper section guide portion 200, the heat exchange portion 400, the lower section guide portion 300, and to the first lower end opening 310, the cross-sectional area of the flow path does not substantially change in theory.

[0130] For the second flow path R2, which is rotationally symmetrical to the first flow path R1, further details are described below.

[0131] 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 region on the right side perpendicular to the stacking direction, and at the second upper end opening 210, the portion where the right side upper end portions of the packing pieces B-A are adhered to each other is divided into a plurality of units. In the right upper section guide portion 202, after passing downward through the portion where the right side upper end portions of the packing pieces B-A are adhered to each other, the units of the first flow path R1 are separated from each other in the stacking direction, and on the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases in the direction perpendicular to the stacking direction to approximately 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 entering the heat exchange portion 400 from the upper section guide portion 200.

[0132] In the case of continuing downward from the heat exchange section 400 to the lower section guide section 300, in contrast to the case in the upper section guide section 200, the unit of the second flow path R2 is flat downward by the width of the substantially packing pieces A, B, and on the one hand, the dimension in the stacking direction gradually becomes large, and on the other hand, the dimension in the direction perpendicular to the stacking direction gradually becomes small to the width of the second lower end opening 220, that is, the thickness becomes large and the width becomes small, and in the right lower section guide section 302, the portions where the right side lower end portions of the packing pieces B-A adhere to each other are merged to reach the second lower end opening 320.

[0133] Thus, in the second flow path R2, the entire section flow path from the second upper end opening 220, through the upper section guide section 200, the heat exchange section 400, the lower section guide section 300, to the second lower end opening 320, the cross-sectional area of the flow path is substantially not changed in theory.

[0134] As described above, in the present embodiment, the first and second upper end openings 210, 220, which are the upper end openings of the first and second flow paths R1, R2, the sum of the opening areas is consistent with the sum of the cross-sectional areas of the flow paths in each portion from the top to the bottom. 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, the sum of the opening areas is consistent with the sum of the cross-sectional areas of the flow paths in each portion from the top to the bottom, that is, the opening areas of 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 each flow path R1, R2 can be greatly improved, and the resistance of the packing module 1 can be reduced, which will be described in further detail later.

[0135]

Rectifier piece

[0136] Thus, when the rectifier pieces 230, 240, 330, 340 are embedded in each guide section 201, 202, 301, 302, that is, the rectifier pieces 230, 240, 330, 340 are embedded in the first and second flow paths R1, R2, respectively, since each rectifier piece 230, 240, 330, 340 is formed in a folded shape, and the extension direction of the folds of the rectifier pieces 230, 240, 330, 340 corresponds to the extension path of the first and second flow paths R1, R2, respectively, the thickness of each rectifier piece 230, 240, 330, 340 is very different from the cross-sectional area of the first and second flow paths R1, R2, so that the passing efficiency of the first and second flow paths R1, R2 is not affected.

[0137] Further, in the present embodiment, the first upper end opening 210 and the second upper end opening 220, which are the upper end openings of the first and second flow paths R1, R2, are arranged side by side in a direction perpendicular to the stacking direction, and have substantially the same width, so that the left upper rectifier fin 230 and the right upper rectifier fin 240, which are respectively located in the left upper guide portion 201 and the right upper guide portion 202, have substantially the same configuration of the accommodation space, and are arranged in a rotational symmetry manner, so that the left upper rectifier fin 230 and the right upper rectifier fin 240 can be configured by using the same components.

[0138] Similarly, the first lower end opening 310 and the second lower end opening 320, which are the lower end openings of the first and second flow paths R1, R2, are arranged side by side in a direction perpendicular to the stacking direction, and have substantially the same width, so that the left lower rectifier fin 330 and the right lower rectifier fin 340, which are respectively located in the left lower guide portion 301 and the right lower guide portion 302, have substantially the same configuration of the accommodation space, and are arranged in a rotational symmetry manner, so that the left lower rectifier fin 330 and the right lower rectifier fin 340 can be configured by using the same components.

[0139] 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 configurations of the accommodation spaces of the rectifier fins 230, 240, 330, 340 are made substantially the same, so that the left upper rectifier fin 230, the right upper rectifier fin 240, the left lower rectifier fin 330, and the right lower rectifier fin 340 can be configured by using the same components. Thus, when the filler module 1 is manufactured, only the filler sheet A, the filler sheet B, and the common rectifier fin are needed, so that the production cost of the filler module 1 is significantly reduced, and the assembly efficiency is significantly improved.

[0140] 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, as with the conventional filler module, 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 with the filler sheets A and B in between, and the upper and lower end openings, and is an equivalent embodiment to the first embodiment described above.

[0141] 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 with the filler sheets A and B in between, and the upper and lower end openings, and is an equivalent embodiment to the first embodiment described above.

[0142] [Second Embodiment]

[0143] The filler module 1' of the second embodiment of the preferred embodiment of the present application is different from the filler module 1 of the first embodiment in that the rectifier fins are provided only in the first flow path R1, i.e. the left upper path rectifier fin 230 provided in the left upper segment guide portion 201 of the first flow path R1 and the left lower path rectifier fin 330 provided in the left lower segment guide portion 301 of the first flow path R1, and no rectifier fin is provided in the second flow path R2. Thus, in the present embodiment, the first flow path R1 is used as a water spraying passage and the second flow path R2 is used as an air induction passage.

[0144] As shown in FIG. 1, the filler module 1' of the second embodiment of the preferred embodiment of the present application is different from the filler module 1 of the first embodiment in that the rectifier fins are provided only in the first flow path R1, i.e. the left upper path rectifier fin 230 provided in the left upper segment guide portion 201 of the first flow path R1 and the left lower path rectifier fin 330 provided in the left lower segment guide portion 301 of the first flow path R1, and no rectifier fin is provided in the second flow path R2. Thus, in the present embodiment, the first flow path R1 is used as a water spraying passage and the second flow path R2 is used as an air induction passage. Figures 10-12 As shown in FIG. 1, the filler module 1' of the second embodiment of the preferred embodiment of the present application is different from the filler module 1 of the first embodiment in that the rectifier fins are provided only in the first flow path R1, i.e. the left upper path rectifier fin 230 provided in the left upper segment guide portion 201 of the first flow path R1 and the left lower path rectifier fin 330 provided in the left lower segment guide portion 301 of the first flow path R1, and no rectifier fin is provided in the second flow path R2. Thus, in the present embodiment, the first flow path R1 is used as a water spraying passage and the second flow path R2 is used as an air induction passage.

[0145] On the other hand, the cold air introduced into the filler module 1' from the part of the width of the second lower end opening 320, i.e. the lower end opening, arranged in the stacking direction on the right side of the arrow in the filler module 1' via the second flow path R2, enters the right lower segment guide portion 302, and based on the flow properties of the gas fluid itself, the thickness of the flow path is gradually limited by the right lower segment guide portion 302 in the stacking direction, and the width of the flow path is gradually expanded to the full width range of the second heat exchange portion 402, and the cold air is effectively heat-exchanged with the hot water attached to the wall portion of the first heat exchange portion 401 through the filler sheets A and B. Then, in the right upper segment guide portion 202, the width of the flow path is gradually limited to the part of the width of the second upper end opening 220, i.e. the upper end opening, arranged in the stacking direction, and the thickness of the flow path in the stacking direction is gradually expanded to 2d, and the cold air is discharged from the second upper end opening of the filler module 1'.

[0146] 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 is not affected by the gravity as in the water flow, even without the rectifier fins, when ensuring the same air flow through the second flow path R2 as in the first embodiment, the cooling efficiency of the filler module 1' can be substantially the same as that of the first embodiment, however, at this time, 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 electric energy can be effectively saved. And, because the filler module 1' in the present embodiment can obtain smaller wind resistance, it is more suitable for a cooling tower without a fan, such as a hyperbolic cooling tower, which uses a passive air suction mode.

[0147] In the present embodiment, as a preferred manner, the upper and lower end openings of the first flow path R1 and the second flow path R2 are located on the same side in the filler module width direction, and further, by the arrangement of the filler pieces A and B, a good water isolation 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.

[0148] Further, in the present embodiment, as shown in Figure 11 the upper end portion of the filler piece 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 piece A is biased to the rear side by a distance of d / 2, and the rear half of the first upper end opening 210 formed by the filler piece A is formed. Further, a left sealing edge portion 215A is formed at the left end edge of the filler piece A, which is biased to the front side by a distance d from the rear half of the first upper end opening 210, i.e. the base position O A of the heat exchange portion 400 of the filler piece A.

[0149] Further, at the upper end portion of the filler piece 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, the front half of the second upper end opening 210 of the second flow path R2 on the rear side formed by the filler piece A is formed by biasing to the front side by a distance of d / 2.

[0150] 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 rear side offset by a distance d / 2, a left edge sealing portion 215B is formed. The left edge sealing portion 215B extends linearly in the up-down direction.

[0151] 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.

[0152] Thus, when the filler sheet A and the filler sheet B adjacent to the front side thereof are assembled in contact with 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.

[0153] 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 showered 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 easily seeped out from the left edge sealing portion 215 when the hot water is guided into the heat exchange portion 400.

[0154] On the other hand, after the hot water is guided from the first upper end opening 210 into 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.

[0155] 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, its structure 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 of the filler sheet A are offset arranged, so that 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, a continuous left sealing edge portion 215A, 215B is formed, so that water leakage from the left sealing edge 215 can be effectively avoided, especially water leakage from the left sealing edge 215 at the part of the upper segment guide portion 200 and the lower segment guide portion 300.

[0156] Further, in the present embodiment, for the sealing edge portion 215 formed by the left sealing edge portion 215A, 215B, any joining method can be used, and from the perspective of assembly convenience, it is preferred to use pressure welding to join the sealing edge portion 210. This is because, when using equipment to assemble the filler sheets A, B and the rectifier sheets 230, 330, by aligning the filler sheet B and the filler sheet B adjacent in the front-rear direction, since the filler sheets A, B are offset to each other at the right side part of the upper and lower end edges, the welding operation of the filler sheets B-A can be completed by operating the pressure welding equipment to weld the sealing edge portion 215 and the right side part of the upper and lower end edges of the filler sheets B-A in this state.

[0157] Thus, by loading the rectifier sheets 230, 330 between the filler sheets B-A and welding the sealing edge portion 215 and the right side part of the upper and lower end edges of the filler sheets B-A, the filler sheets B-A in front and back of the stacking direction form a module with very high structural stability, and then the modules formed by the filler sheets B-A in the stacking direction are combined and pasted. Since the strength and stability of a single module are good, the difficulty of module assembly can be greatly reduced, and the efficiency of assembling the module of the filler sheets B-A into the filler module 1' can be improved.

[0158] In the drawings of the present embodiment, for the convenience of assembly and processing, the right sealing edge does not have the same structure as the left sealing edge 215. However, this does not constitute a limitation on the structure of the right sealing edge, and of course the right sealing edge can also have the same structure as the left sealing edge 215.

[0159]

Third Embodiment

[0160] The filler module 1" of the third embodiment as the 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.

[0161] 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.

[0162] 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.

[0163] 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. In 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.

[0164] 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.

[0165] 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.

[0166] 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 bending of the rectifier at the end face of the first upper end opening 210 can be formed due to the interference of the rectifier arranged in the bending manner. As for the left side upper end edges of the filler pieces A-B, only the sealing by gluing can be performed after convergence.

[0167] In contrast, in the present embodiment, by retracting the rectifier fins into the first upper end opening 210, the avoidance area can be used to continuously pressure weld the left upper end edge of the filler sheet A-B.

[0168] In this way, on the one hand, the connection strength of the left upper end edge of the filler sheet A-B is improved, so that after the multi-layered filler sheets A and B are stacked, the overall strength of the filler module 1" can be significantly improved.

[0169] 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 sheet 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.

[0170] 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 and 215B on the left edges of the filler sheet A and the filler sheet 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.

[0171] 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. by using a simple convex-concave joint.

[0172] Of course, the right edge sealing can also be used in the same way as 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 sheet A and B to the same direction as the left edge, a right edge sealing can be formed. Thus, the first flow path can be completely sealed.

[0173] 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 can be greatly improved. In this way, the firmness, reliability, and durability of the filler module 1" during transportation, operation, installation, and daily operation can be greatly improved.

[0174] [Fourth Embodiment]

[0175] 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, and the manufacturing cost of the filler module can be reduced. 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 by 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 made by describing the position of the filler sheet A before being flipped over.

[0176] 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 state of being flipped over by 180° about the horizontal axis of the body portion of the filler sheet A.

[0177] 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, so that the first upper end opening 210 is formed between the left upper offset portion of the filler sheet A and the left lower offset portion of the filler sheet B, and the first lower end opening 310 is formed between the left lower offset portion of the filler sheet A and the left upper offset portion of the filler sheet B, and the first upper end opening 210 and the first lower end opening 310 are respectively communicated with 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 vertical direction, thereby forming the first flow path R1.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] 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.

[0185] 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°.

[0186]

Cooling tower 1

[0187] Figure 10 is a schematic view of a cooling tower made based on the filler module 1 of the present embodiment.

[0188] 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.

[0189] 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 cold 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.

[0190] 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.

[0191] Working state one:

[0192] 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.

[0193] 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.

[0194] 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.

[0195] 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.

[0196] 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 mixing with the dry hot air, and the unsaturated hot air is gradually cooled and has a small amount of water after being discharged to the atmosphere by the fan 107 and the exhaust port 108, which greatly reduces the amount of fog formed.

[0197] In the present embodiment, by switching the spraying part 104, the spraying space 105a and the induced space 105b can be flexibly switched, i.e., the spraying space 105a is stopped from being sprayed with hot water, and the induced space 105b is sprayed with hot water, so that the functions of the spraying space 105a and the induced space 105b are 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 induced 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.

[0198] Working state two:

[0199] When operated in summer, the induced 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.

[0200]

Cooling tower 20

[0201] 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.

[0202] 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 induced space 205b for air exhaust; of course, the cover plate 109 can be arranged for both the spray space 105a and the induced space 205b, and the cover plate 109 can be arranged as a continuous plate or a plurality of plates combined, and the cover plate 109 can be flipped or 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 induced space 205b can be switched.

[0203] Working state one:

[0204] This working state is especially suitable for winter in northern China. 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 cannot function as an induced space 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 induced space 205b.

[0205] Therefore, the cooling tower 20 only has dry hot air drawn out of the exhaust port 108 by the fan 107, so that the moisture in the hot air discharged from the cooling tower 20 is reduced as much as possible, thereby further improving the fog dissipation capacity of the cooling tower 20 in winter, and since the air discharged is only dry hot air, the amount of water discharged from the cooling tower 20 is less, which is more beneficial to water saving.

[0206] In the case where the cover plate 109 is arranged openable (flat or open or detachable) for both the spray space 205a and the induced space 205b, by opening the cover plate above the spray space 205a and closing the cover plate above the induced space 205b, and adjusting the spray part 104, the functions of the spray space 205a and the induced 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 induced space 205b is cleaned, thereby avoiding shutdown of the cooling tower 20.

[0207] 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.

[0208] Working state two:

[0209] 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 space 205b is 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.

[0210] 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 filler 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.

[0211] In the above embodiment, the flow regulating piece 230 is provided in the left upper segment guide part 201 formed between the filler pieces B-A in the stacking direction of the filler modules 1 of the upper segment flow guide part 200 of the first flow path R1.

[0212] Further, the flow regulating piece 240 is provided in the right upper segment guide part 202 formed between the filler pieces A-B in the stacking direction of the upper segment flow guide part 200 of the second flow path R2.

[0213] On the other hand, the flow regulating piece 330 is provided in the left lower segment guide part 301 formed between the filler pieces B-A in the stacking direction of the lower segment flow guide part 300 of the first flow path R1.

[0214] Further, the flow regulating piece 340 is provided in the right upper segment guide part 202 formed between the filler pieces A-B in the stacking direction of the lower segment flow guide part 300 of the second flow path R2.

[0215] 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 rear side is biased at the right-angled trapezoidal region, and for the filler sheet B, the front side is biased, 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 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.

[0216] 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 from the first upper end opening 210 to the heat exchange portion 400 are formed. Each guide flow path has a thick upper end in the stacking direction and a small width in the horizontal direction, and a lower end with a small thickness and a large width. Thus, 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.

[0217] 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.

[0218] 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.

[0219] 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.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] [5th Embodiment]

[0224] In the filler module 1000 of the present embodiment, as in 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

[0225] The difference from the above-described embodiments is the position where 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 in the middle portion, and the upper end openings W1 and W2 of the second flow path 1000W as the second upper end opening are provided on the left side and the right side of the upper end opening G, respectively. That is, in the present embodiment, the second flow path 1000W has two upper end openings W, and is provided so as to sandwich the upper end opening G of the first flow path 1000G.

[0226] In the present embodiment, the upper end opening G of the first flow path 1000G is communicated 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 the upper end opening G, which occupies the middle portion in the upper end width direction of the filler module 1000, is guided to the first heat exchange portion 401, which occupies substantially the entire width of the filler module 1000.

[0227] The two upper end openings W1 and W2 of the second flow path 1000W are communicated 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 the upper end openings W1 and W2, which occupy the portions on both sides of the upper end opening G of the first flow path 1000G in the upper end width direction of the filler module 1000, are guided to the second heat exchange portion 402, which occupies substantially the entire width of the filler module 1000.

[0228] ​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 1000G. 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 portions of the first heat exchange portion 401 and the second heat exchange portion 402.

[0229] 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.

[0230] In the present embodiment, by biasing the filler sheet 1000B and the filler sheet 1000A from the upper end opening G toward the region of the portion of the first heat exchange portion 401 of 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, the filler sheet 1000A and the filler sheet 1000B are brought close to each other at the portion of the upper section guide portion 200 due to the formation of the first biasing portions 1100A, 1100B.

[0231] 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 region of the portion of the second heat exchange portion 402 of 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, the filler sheet 1000B and the filler sheet 1000A are brought close to each other at the portion of the upper section guide portion 200 due to the formation of the second biasing portions 1200B, 1200A.

[0232] 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.

[0233] Further, the thickness dimension of the first and second upper section 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.

[0234] 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.

[0235] 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 a width gradually increasing from top to bottom.

[0236] 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 a width gradually increasing from top to bottom.

[0237] In the present embodiment, as described above, since the front projection of the packing sheet 1000A, 1000B is substantially rectangular, the first upper end opening 1100 of the first upper section guide portion 200G formed by the first offset portion 1100B, 1100A is formed as an inverted substantially triangular shape; and the second upper end opening 1200 of the second upper section guide portion 200W formed by the second offset portion 1200A, 1200B is formed as an inverted substantially right-angled triangular shape located at the upper end left and right corner portions of the packing sheet 1000A, 1000B. At this time, the first upper end opening G and the second upper end openings W1, W2 are located at the upper end edge of the packing module 1000.

[0238] 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 triangular shapes are also formed. The function of the longitudinal rectifying portions is to preliminarily separate the first and second upper section guide portions 200G, 200W of the first and second flow paths 1000G, 1000W, so as to ensure that the flow amount in each flow guide groove is substantially uniform in the oblique rectifying portions below.

[0239] 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, and providing the first and second rectifying sheets 1300G, 1300W, the first and second lower end guide portions 400G, 400W can also be formed by providing the same offset portions, and the third and fourth rectifying sheets 1300G', 1300W' can also be provided. Further, the same first and second lower end openings are formed.

[0240] 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.

[0241] (Usage Example 1)

[0242] In the present embodiment, since the first upper end opening G of the first flow path 1000G is located at the middle of the width direction of the packing module 1000, and the first upper end opening W of the second flow path 1000W is located at both sides of 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

[0243] ​In the present use example, the lower end of the partition plate 2005 provided above the filler modules 1000 for separating the air flow path and the spray water flow path, and the sealing portion between the filler modules 1000, are all located within the width direction dimension of the filler modules, without the lower end of the partition plate 105 being located at the intersection portion of the filler modules as described above. In this way, the sealing between the filler modules 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 in from below the filler modules 1000 exchanges heat with the hot water in the adjacent flow path after passing through the filler modules 1000 and is discharged above the filler modules 1000, and the absolute humidity of the cold air does not change.

[0244] However, the air discharged above the filler modules 1000 after heat exchange with the hot water in the adjacent flow path becomes dry hot air, and the air temperature increases while the absolute humidity remains unchanged, so the relative humidity decreases significantly.

[0245] In the present use example, since the partition plate 2005' is also provided below the filler modules 1000, the spray hot water after passing through the filler modules 1000 in the cooling tower 2000 supplies moisture to the cold air drawn below the filler modules 1000 as little as possible. In the filler modules 1000, the cold air and the hot water in the adjacent flow path are isolated from each other, and moisture is not supplied to the air flow path, and further, the cold air drawn below the filler modules 1000 is prevented from obtaining moisture from the spray portion due to the separation of the partition plate 2005.

[0246] Therefore, in the present use example, by separating the air flow path and the spray water as completely as possible in the cooling tower 2000, moisture is supplied to the drawn air as little as possible; on the other hand, in the spray water flow path, since the valve plate 2009 in the closed state is provided above the spray head, the hot gas of the spray hot water is mixed into the discharged air as little as possible, and the cold air drawn below the filler modules 1000 is also separated by the partition plate 2005', so the spray hot water forms a closed flow path and supplies moisture to the drawn air and the discharged air of the cooling tower 2000 as little as possible. Therefore, even in winter in northern China, the mist discharged from the cooling tower 2000 can be greatly reduced.

[0247] (Use example 2)

[0248] In addition, the valve plate 2009 can also be provided in the inoperative state (open or not provided), as shown in Figure 28 Even so, the cold air drawn below the filler modules 1000 only has a small amount of water vapor mixed with the cooled cold air above the partition plate 2005 after the cold air is discharged above the filler modules.

[0249] Since the temperature of the cooled air increases after heat exchange, and the absolute humidity does not change, the saturation is low, and on the other hand, the amount of moisture from the spray flow path itself is limited, so the air after heat exchange, which has a significantly decreased saturation, can be effectively used to absorb the moisture released from the spray portion. The cooling tower 2100 of the present use example 2 can also effectively achieve the fog elimination effect, except in the case where the air temperature is very low in winter.

[0250] 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 portion between the adjacent packing 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 pass all the air taken into the cooling tower 2000 through the first flow path 1000G as much as possible, while ensuring the airtightness between the lower end of the partition 2005 and the packing module 1000.

[0251] However, the portion between the packing modules 1000 inevitably has a certain gap, otherwise the installation of the packing modules 1000 will be a problem. According to the packing module 1000 of the present embodiment, by providing the first upper end opening G at the middle of the width direction of the packing module 1000, and providing 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 are all the second upper end openings W, so the second upper end opening W can be set as the inlet of the hot water spray flow path. 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, the gap between the packing modules 1000 is inevitably provided in the air flow path, so that a part of the air does not pass through the packing modules 1000, but directly flows through the gap between the packing modules 1000, which can cause a problem of reduced heat exchange efficiency. Furthermore, in the case where the gap between the packing modules 1000 is too large due to construction errors, mistakes, etc., the air flow through the gap between the packing modules 1000 will significantly increase, so that the uniformity of the air resistance of the entire cooling tower cannot be guaranteed, which will inevitably affect the uniformity of the stacking direction of the packing modules and the heat exchange efficiency between the packing modules in the entire cooling tower.

[0252] The packing module 1000 of the present embodiment can properly solve the above problems.

[0253] (Use example 3)

[0254] As the use example 3 of the packing module 1000 of the present embodiment, in addition to the advantages of the use examples 1 and 2 described above, the heat exchange efficiency of the cooling tower can be further improved, and the cost of the packing module can be significantly reduced, and the convenience of installation and maintenance is further enhanced. The following will be described in detail.

[0255] In the present use example, as shown in Figure 29 the packing module 1000 is used to build the cooling tower 3000, and the following will only describe the differences between the cooling tower 3000 and the previous embodiments.

[0256] In the cooling tower 3000, unlike the previous ones, each packing module 1000 is provided with a specified installation interval 3999 of 300-600mm between each other, and a closing plate 3998 is preferably provided on the mounting seat surface at the interval between the packing modules 1000. If the closing plate 3998 is not provided, the support beam serving as the mounting seat of the packing module 1000 can be made to have a plane corresponding to the interval of the packing module 1000.

[0257] At this time, contrary to the use examples 1 and 2 described above, the second flow path 1000W of the packing module 1000 is preferably made as the air flow path, and the first flow path 1000G is made as the flow path of the sprayed water.

[0258] In this way, when designing the cooling tower 3000, the packing modules 1000 can be intentionally arranged at intervals, and the installation interval 3999 can allow workers to enter and move and investigate the state between the packing modules 1000 when installing and maintaining the packing modules 1000.

[0259] Especially, when installing the packing modules 1000, because the distance of the packing modules 1000 in the stacking direction of the packing modules 1000 is long, the packing modules 1000 are usually divided and stacked only to a specified thickness to form a unit of the packing modules 1000, and the packing modules 1000 are formed by arranging the units in a straight line in the stacking direction of the packing modules 1000 and close to each other. 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 modules 1000 is in a straight line when installed. When the packing modules 1000 do not have the installation interval 3999 between each other in the transverse 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.

[0260] In this regard, according to the present use example, since the installation intervals 3999 are provided between the filler modules 1000 in the lateral direction, when the modules are installed in the stacking direction, the operator can easily adjust the units of the filler modules 1000 by means of the installation intervals 3999. Even if a unit is damaged due to some special accident, the damaged unit can be easily replaced by moving the units before and after the damaged unit to the positions of the damaged unit and adding new units from the end of the stacking direction of the filler modules 1000, thereby completing the repair.

[0261] When the closing plate 3998 is provided in the installation interval 3999, the closing plate 3998 is preferably removable or erected, so that the closing plate 3998 is inactivated. At this time, since the second flow path 1000W is provided 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 requirements in the factory production can be met.

[0262] (Use Example 4)

[0263] Figure 30 is a schematic view of use example 4. In the present use example, intervals are provided between the filler modules 1000 in the lateral direction, similar to use example 3, but ordinary filler modules F are further provided in the intervals.

[0264] As the ordinary filler modules F, any existing filler module can be used. For example, the filler module F formed by simply stacking a plurality of filler sheets, which is the most widely used filler module so far, is used at this time, and there is no separated flow path in the filler module F. For each thin sheet-shaped heat exchange space formed by two adjacent filler sheets in the stacking direction, hot water is poured from the upper end opening, and cold air is sucked into the filler module F from the lower end opening of the filler module F by means of the fan of the cooling tower 4000, so that the air and the hot water are directly contacted to exchange heat.

[0265] As described above, in the present use example, the second flow path 1000W is preferably provided as a hot water pouring flow path, and the first flow path 1000G is provided as an 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 sucked 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 poured into the filler module F directly exchanges heat with the air sucked from the lower end of the filler module F in the filler module.

[0266] 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 upward from the upper end of the filler module F becomes saturated hot air.

[0267] On the other hand, because of the provision of the second upper end openings W1 and W2, the air resistance in the second flow path 1000W is very large, so actually the amount of air discharged upward from the second upper end opening W of the filler module 1000 is very small, compared to the amount of air passing through the filler module F.

[0268] Therefore, the hot air with low saturation discharged mainly from the first upper end opening G of the filler module 1000, the saturated hot air discharged from the filler module F, and the 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.

[0269] According to the filler module 1000 of the present embodiment, by providing the first upper end opening G in the middle of the top end width direction and the second upper end openings W (W1, W2) on both sides of the first upper end opening G, when the filler module 1000 is used to build the cooling tower 2000, 2100, 3000, 4000, etc., it can be more flexible, and the air passage and the hot water passage can also be flexibly arranged. Especially when the first flow path 1000G connected by 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 fog elimination effect, which is particularly suitable for the situation in winter in northern China.

[0270] However, the filler module 1000 and the cooling tower having the same provided by the present embodiment are not limited to the situation described in the present embodiment.

[0271] In the present embodiment, by making the filler module 1000 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 overlapped filler sheets 1000A and 1000B form an alternating stack, the first flow path 1000G contains the first heat exchange portion 401, the second flow path 1000W contains the second heat exchange portion 402, and the first heat exchange portion 401 and the second heat exchange portion 402 overlap to form the heat exchange portion 400.

[0272] The filler sheet 1000A has a bias portion 1100A that is biased to the front side in the stacking direction at the center of the upper-stage guide portion, and bias portions 1100B that are biased to the rear side in the stacking direction at both sides of the upper-stage guide portion. The filler sheet 1000B has a bias portion 1200A that is biased to the rear side in the stacking direction at the center of the upper-stage guide portion, and bias portions 1200B that are biased to the front side in the stacking direction at both sides of the upper-stage guide portion.

[0273] Thus, by stacking the filler sheet 1000A and the filler sheet 1000B, a first upper-end opening G is formed by the bias portions 1100A, 1100B of the filler sheet 1000A and the filler sheet 1000B that are formed at the center of the upper-stage guide portion. A second upper-end opening W is formed by the bias portions 1200A, 1200B of the filler sheet 1000B and the filler sheet 1000A that are formed at both sides of the upper-stage guide portion.

[0274] In the first flow path 1000G, the first upper-end opening G communicates with the first heat exchange portion 401 of the substantially full-width dimension of the filler module 1000, and in the second flow path 1000W, the second upper-end opening W communicates with the second heat exchange portion 402 of the substantially full-width dimension of the filler module.

[0275] In the present embodiment, a lower-stage guide portion is further provided below the heat exchange portion, and for the first and second flow paths 1000G, 1000W, the lower-stage guide portion is inverted with respect to the first and second upper-stage guide portions 200G, 200W, and includes corresponding bias portions, and a rectifier sheet 1300G', 1300W' that is formed by a first and second lower-end opening, and a slanted flow guide portion that is embedded in the guide portion including the bias portions, and that connects the slanted flow guide portion and the first and second heat exchange portions 401, 402. At this time, the same parts as the rectifier sheets 1300G, 1300W can be used for the rectifier sheets 1300G', 1300W', and they can be inverted.

[0276] The rectifier fins 1300G, 1300W are located at the upper section guide portion of the filler module 1000, and in particular, when guiding the hot water flow, the sprayed hot water needs to be introduced to the first heat exchange portion 401 or the second heat exchange portion 402 of the substantially full width from the first upper end opening G or the second upper end opening W (W1, W2) in the middle of the width direction, so the lower end of the rectifier fin is bent to form a guide groove, and gradually flattens to make the guided fluid uniformly distributed on the surface of the heat exchange portion of the filler sheet 1000A, 1000B. However, for the rectifier fins 1300G", 1300W", since they are in the lower section guide portion, when guiding the sprayed water out of the filler module 1000, uniformity does not need to be considered, so the flattened part can be removed and only the guide flow path part formed by bending is retained. In this way, it can also avoid the accumulation of impurities in the water caused by the flattening of the upper end of the rectifier fins 1300G', 1300W' which narrows the flow path, especially when the sprayed hot water flows out of the filler module 1000, and the long-term use of the filler module 1000.

[0277] The filler module of the preferred embodiment of the present application and the cooling tower having the same are described in detail above, but those skilled in the art can make various modifications, changes, combinations, etc. on this basis, and these modifications, changes, combinations all fall within the protection scope of the claims of the present application.

[0278] In the present embodiment, the above-mentioned 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.

[0279] The cooling tower 20 of the present 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 portion of the partition plate 105. A plurality of interval spaces 205a, 205b are enclosed by the cover plate 109, the partition plate 105 and the filler module 1. In the present 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 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 as to switch the spray space 205a and the air induction space 205b.

[0280] Working state one:

[0281] 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 spraying space 205a, so that the spraying space 205a cannot play the role of air induction in principle, and only hot water passes through the flow path R1 or R2 of the corresponding filler module of the spraying space 205a downward, so that in the exhaust layer 106 of the cooling tower 20, only dry hot air from the induction space 205b.

[0282] Therefore, the cooling tower 20 only has dry hot air drawn out of the exhaust port 108 by the fan 107, so that the moisture in the hot air discharged by 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 by the cooling tower 20 is also less, which is more conducive to water saving.

[0283] In the case that the cover plates 109 arranged above the spraying space 205a and the induction space 205b are openable (flat open or opposite open or removable), by opening the cover plate above the spraying space 205a and closing the cover plate above the induction space 205b, and adjusting the spraying part 104, the functions of the spraying space 205a and the induction space 205b can be exchanged as the above-mentioned cooling tower 10, and the flow path R1 or R2 of the filler module 1 corresponding to the original induction space 205b is cleaned, thereby avoiding shutdown of the cooling tower 20.

[0284] Of course, by opening only the cover plate 109, the same working state as the above-mentioned cooling tower 10 can be achieved, and the working efficiency and working result are also approximately the same.

[0285] Working state two:

[0286] 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 hot water is sprayed to the induction space 205b as well as the spraying space 205a, and the cooling tower 20 realizes the working state of improving heat exchange efficiency in summer as the above-mentioned cooling tower 10.

[0287] In the cooling tower 20 of the present embodiment, the cover plate 109 arranged above the interval space 205a, 205b is a flat plate, but is not limited thereto, and can be a plate extending from the partition plate 105 on both sides of the filler module 1 in the stacking direction of the interval space 205a, 205b to the middle and lapping to close the interval space 205a, 205b, and forming a top corner upward or downward at the lapped place, that is, as long as the upper part of the interval space 205a, 205b can be closed, there is no limitation on the constituting mode of the cover plate 109.

[0288] In the above embodiment, the rectification fin 230 is provided in the left upper section guide portion 201 of the upper section flow guide portion 200 of the first flow path Rl formed between the filler sheets B-A in the stacking direction of the filler module 1.

[0289] Further, the rectification fin 240 is provided in the right upper section guide portion 202 of the upper section flow guide portion 200 of the second flow path R2 formed between the filler sheets A-B in the stacking direction.

[0290] On the other hand, the rectification fin 330 is provided in the left lower section guide portion 301 of the lower section flow guide portion 300 of the first flow path Rl formed between the filler sheets B-A in the stacking direction.

[0291] Further, the rectification fin 340 is provided in the right upper section guide portion 202 of the lower section flow guide portion 300 of the second flow path R2 formed between the filler sheets A-B in the stacking direction.

[0292] Since the first upper end opening 210 and the second upper end opening 220 each occupy approximately half of the width of the filler module 1, in practice, the rectification fin 230 is embedded in a substantially right-angled trapezoidal region formed by extending from approximately the middle of the upper edge of the filler sheet B-A downward toward the left side edge of the upper section guide portion 200, then rightward along the lower end portion line of the upper section guide portion 200 to the right side edge of the upper section guide portion 200, and then upward toward the approximately middle of the upper edge of the filler sheet A(B). For the filler sheet A, the right-angled trapezoidal region is biased toward the rear side, and for the filler sheet B, the right-angled trapezoidal region is biased toward 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 sheets A-B, are in close contact at the periphery of the first upper end opening 210, and the front side filler sheet B and the rear side filler sheet A, i.e., the filler sheets B-A, are separated by a width of 2d in the stacking direction at the first upper end opening 210. That is, in the 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 lower end where the heat exchange portion 400 is connected is the interval d between the filler sheets A and B, thereby forming the space of the left upper section guide portion 201.

[0293] The cross section of the rectifying fin 230 in the horizontal direction is in a meandering shape extending perpendicular to the stacking direction. The meandering amplitude is large and the meandering span is small at the upper part near the first upper end opening 210. During the extension from the top to the heat exchange part 400, the meandering amplitude gradually decreases and the meandering span gradually increases to fill the space of the left upper section guide part 201. By making the rectifying fin 230 meander in the horizontal direction, multiple guide flow paths are formed from the first upper end opening 210 to the heat exchange part 400. Each guide flow path has a top end with a large thickness in the stacking direction and a small width in the horizontal direction, and a bottom end with a small thickness and a large width. Thus, 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 part 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 top to the bottom to reduce the resistance of the fluid. Good passing efficiency is achieved for both the hot water sprayed from above and the air sucked from below to above.

[0294] The rectifying fin 240 located in the space of the right upper section guide part 202 is also similarly configured, except that it is rotationally symmetric with the rectifying fin 240 in the horizontal direction.

[0295] For the rectifying fins 330, 340, which are located in the left lower section guide part 301 formed by offsetting the area of the inverted right-angled trapezoidal region of the filler sheet B-A at the lower section guide part 300 to the outside of the stacking direction, and the right lower section guide part 302 formed by offsetting the area of the inverted right-angled trapezoidal region of the filler sheet A-B at the lower section guide part 300 to the outside of the stacking direction, respectively, multiple flow paths are formed in the left lower section guide part 301 and the right lower section guide part 302, respectively, with a top end having a small thickness in the stacking direction and a large width in the horizontal direction, and a bottom end having a large thickness and a small width. The water from the heat exchange part 400, which is approximately the full width of the first and second flow paths R1, R2 of the filler module 1, is guided to the first and second lower end openings 310, 320, which are approximately half the width.

[0296] That is, for the rectifying fins 330, 340, the meandering amplitude is large and the meandering span is small at the first and second lower end openings 310, 320. During the extension from the bottom to the heat exchange part 400, the meandering amplitude gradually decreases and the meandering span gradually increases.

[0297] For the rectifying fin 330 located in the space of the left lower section guide part 301 and the rectifying fin 340 located in the space of the right lower section guide part 302, they are rotationally symmetric in the horizontal direction.

[0298] Therefore, in the case that the first and second upper end openings 210, 220 and the first and second lower end openings 310, 320 are each approximately half the width of the filler module 1, if the vertical direction lengths of the upper and lower section guide portions 200, 300 are made the same, 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 can be formed in a rotational symmetrical structure, and thus the rectifier fins 230, 240, 330, 340 can be made the same component, so that the filler module 1 only needs three components, i.e., the filler sheet A, the filler sheet B, and the universal rectifier fin, when being manufactured, so that not only the mold cost and the component production cost for manufacturing the filler module 1 are significantly reduced, but also when assembling the filler sheet A, the filler sheet B, and the rectifier fin, the model difference of the rectifier fins does not need to be considered, so that the assembly is convenient, and thus the overall production cost of the filler module 1 is greatly reduced.

[0299] According to the above 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 stacked in the stacking direction, and in the case that the thicknesses of the filler sheet A and the filler sheet B are not considered, the total size of the openings in the stacking direction is approximately consistent with the stacking thickness of the filler module in the stacking direction.

[0300]

Fifth Embodiment

[0301] In the filler module 1000 of the present embodiment, similarly to the above 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, 1000B. That is, as shown in FIG. 10, in the filler module 1000, a first flow path 1000G is formed between the filler sheets 1000A-1000B in the front-to-back direction of the stacking direction of the filler module, and a second flow path 1000W is formed between the filler sheets 1000B-1000A. Figure 17

[0302] Unlike the above embodiments, the first flow path 1000G and the second flow path 1000W differ in the setting positions of the upper end openings thereof. 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 set to 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 set to the left side of the upper end opening G and an upper end opening W2 set to 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 set in a manner of sandwiching the upper end opening G of the first flow path 1000G.

[0303] ​In the present embodiment, the upper end opening G of the first flow path 1000G is communicated 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 the upper end opening G located at the middle portion in the width direction of the upper end of the filler module 1000 is guided to the first heat exchange portion 401 of the substantially full width of the filler module 1000.

[0304] The two upper end openings W1, W2 of the second flow path 1000W are communicated 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 the upper end openings W1, W2 located at both sides of the upper end opening G of the first flow path 1000G in the width direction of the upper end of the filler module 1000 are guided to the second heat exchange portion 402 of the substantially full width of the filler module 1000.

[0305] Specifically, in the front-rear direction of the illustrated filler sheet stacking, 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 1000G. 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.

[0306] Further, for the filler sheet A and the filler sheet B, the upper section guide portion 200 of the first flow path 1000G and the second flow path 1000W is arranged above the heat exchange portion 400 formed by the first heat exchange portion 401 and the second heat exchange portion 402 arranged in layers.

[0307] In the present embodiment, by biasing the filler sheet 1000B and the filler sheet 1000A from the upper end opening G to the area of the portion of the first heat exchange portion 401 at the upper section guide portion 200 in opposite directions to each other, the first biasing portion 1100B, 1100A is formed, the distance between them is increased, and thus the first upper end opening portion 1100 of the first upper section guide portion 200G is formed. Further, for the upper section guide portion 200 of the filler sheet 1000A and the filler sheet 1000B, the filler sheet 1000A and the filler sheet 1000B are brought together at this portion due to the formation of the first biasing portion 1100A, 1100B.

[0308] On the other hand, by biasing the filler sheet 1000A and the filler sheet 1000B at the upper section guide portion 200 from the regions of the second upper end openings W1, W2 on both sides of the upper end opening G to the portion of the second heat exchange portion 402 in opposite directions to each other, the second biasing portions 1200A, 1200B are formed, the distance between them is increased, and thus the second upper end opening portion 1200 of the second upper section guide portion 200W is formed. Furthermore, 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 this portion due to the formation of the second biasing portions 1200B, 1200A.

[0309] 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 furthermore, 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. Furthermore, in the first flow path 1000G, the first upper end opening G occupying a portion of the width of the filler module 1000 from the middle communicates to the first heat exchange portion 401 occupying substantially the full width of the filler module 1000, and in the second flow path 1000W, the second upper end openings W1, W2 occupying the partial widths of the filler module 1000 from both sides communicate to the second heat exchange portion 402 occupying substantially the full width of the filler module 1000. Thus, in one unit of the second flow path 1000W formed by the filler sheets 1000A-1000B, the second upper end openings W1, W2 of the second flow path 1000W communicate to the common second heat exchange portion 402.

[0310] Furthermore, the thickness dimension of the first and second upper section openings G, W1, W2 in the stacking direction of the filler module 1000 is greater than the distance of the respective corresponding filler sheets 1000A, 1000B in the stacking direction at the heat exchange portion 400.

[0311] 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 rectifying sheet is further provided in the respective first and second upper section guide portions 200G, 200W.

[0312] As the first flow rectifying 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 communicate the first upper end opening G to the first heat exchange portion 401 occupying substantially the full width. Therefore, the first flow rectifying 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.

[0313] Further, as the second rectifying fin 1300W in the second flow path 1000W, a second upper section guide portion 200W provided between the second upper end openings W1, W2 and the second heat exchange portion 402 functions to connect the second upper end openings W1, W2 to the second heat exchange portion 402 of substantially full width. Therefore, the second rectifying fin 1300W provided in the second upper section guide portion 200W is formed in a substantially two right-angled trapezoidal shape having a plurality of flow guide grooves with a gradually increasing width from top to bottom.

[0314] In the present embodiment, as described above, since the front projection of the filler sheet 1000A, 1000B is substantially rectangular, the first upper end opening portion 1100 of the first upper section guide portion 200G formed by the first offset portion 1100B, 1100A is formed in an inverted substantially triangular shape; and the second upper end opening portion 1200 of the second upper section guide portion 200W formed by the second offset portion 1200A, 1200B is formed in an inverted substantially right-angled triangular shape located at the upper end left and right corner portions of the filler 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 filler module 1000.

[0315] Accordingly, at positions of the first and second rectifying fins 1300G, 1300W corresponding to the first and second upper end opening portions 1100, 1200 of the first and second upper section guide portions 200G, 200W, longitudinal rectifying portions in an inverted substantially triangular shape and an inverted substantially right-angled triangular shape are also formed. The longitudinal rectifying portions function to preliminarily separate the first and second upper section guide portions 200G, 200W of the first and second flow paths 1000G, 1000W to ensure that the flow rates in the flow guide grooves are substantially uniform in the oblique rectifying portions therebelow.

[0316] Further, in the present embodiment, in addition to the first and second rectifying fins 1300G, 1300W formed by providing offset portions to form the first and second upper end opening portions 1100, 1200 in the first and second upper section guide portions 200G, 200W, third and fourth rectifying fins 1300G', 1300W' can be formed by providing the same offset portions in the first and second lower section guide portions 400G, 400W. Further, the same first and second lower end openings can be formed.

[0317] Based on the filler module of the present embodiment, when a cooling tower is constructed, a plurality of filler 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.

[0318] (Usage Example 1)

[0319] In the present embodiment, since the first upper end opening G of the first flow path 1000G is located at the middle of the width direction of the filler module 1000, and the second upper end opening W of the second flow path 1000W is located at both sides of the width direction of the filler module 1000, when the filler modules 1000 are arranged side by side, as shown in FIG. 8, a schematic diagram of use example 1 of the filler module 1000 of the present embodiment is shown. Figure 27

[0320] Unlike the first to fourth embodiments, in the present use example, the lower end of the partition plate 2005 arranged above the filler module 1000 for separating the air flow path and the spray water flow path, and the sealing part between the filler module 1000, are all located within the dimension of the width direction of the filler module, without the lower end of the partition plate 105 being located at the joint part of the filler modules as described above. 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 and exchanging heat with the hot water in the adjacent flow path, and being discharged above the filler module 1000, its absolute humidity does not change at all.

[0321] However, the air after heat exchange, which is discharged above the filler module 1000 and exchanges heat with the hot water in the adjacent flow path, becomes dry hot air, and in the case of maintaining the absolute humidity, the air temperature rises, and the relative humidity drops significantly.

[0322] In the present use example, since the partition plate 2005' is also arranged below the filler module 1000, in the cooling tower 2000, the spray hot water after passing through the filler module 1000 supplies moisture to the cold air drawn below the filler module 1000 as little as possible. 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 drawn cold air is discharged above the filler module 1000, due to the separation of the partition plate 2005, it is further avoided to obtain moisture from the spray part.

[0323] Therefore, in the present use example, by separating the air flow path and the spray water as completely as possible in the cooling tower 2000, moisture can be supplied to the drawn air as little as possible; on the other hand, in the spray water flow path, since the valve plate 2009 in a closed state is arranged above the spray head, the hot gas of the spray hot water is mixed into the discharged air as little as possible, and below the filler module 1000, the drawn cold air is also separated by the partition plate 2005', so the spray hot water forms a closed flow path, and supplies moisture to the drawn air and the discharged air of the cooling tower 2000 as little as possible. Thus, even in winter in northern China, the mist discharged by the cooling tower 2000 can be greatly reduced. ​

[0324] (Usage Example 2)

[0325] Alternatively, valve plate 2009 can be set to an inactive state (open or not set), becoming as follows: Figure 28 Even so, as shown, the cold air drawn in below the packing module 1000, after being discharged above the packing module, only has a small amount of water vapor mixed with the heat-exchanged cold air above the partition 2005.

[0326] Because the temperature of the cooled air increases after heat exchange while the absolute humidity remains unchanged, the saturation is low. On the other hand, the amount of water from the spray path is limited. Therefore, the air with significantly reduced saturation after heat exchange can be effectively utilized to absorb the water released from the spray section. Except in cases where the temperature is very low in winter, the cooling tower 2100 of this application example 2 can also effectively achieve the defogging effect.

[0327] In the above-described usage examples 1 and 2, the first flow path 1000G is used as the air flow path, and the second flow path 1000W is used as the hot water spray flow path. Therefore, the portion between adjacent packing modules 1000 is confined to the range of the hot water spray flow path. In this case, the first flow path 1000G, as the air flow path, ensures the airtightness between the lower end of the baffle 2005 and the packing module 1000, allowing as much air as possible drawn into the cooling tower 2000 to flow through the first flow path 1000G.

[0328] Regarding the installation of packing modules, gaps are inevitable between them; otherwise, installation would be problematic. In this embodiment, the packing module 1000 has a first upper opening G located in the middle of its width direction, and second upper openings W located on either side of its width direction. This ensures that adjacent upper openings of adjacent packing modules 1000 are both second upper openings W, which can then be used as inlets for hot water spraying. This effectively reduces air leakage from the installation gaps between the packing modules 1000. In embodiments one through four, gaps between packing modules 1000 inevitably exist in the airflow path, causing some air to bypass the packing modules and flow directly through these gaps, potentially reducing heat exchange efficiency. Furthermore, if the gaps between the packing modules 100 are too large due to construction errors or mistakes, the airflow through the gaps between the packing modules 100 will increase significantly, making it even more difficult to ensure uniform air resistance of the entire cooling tower. This will inevitably affect the stacking direction of each packing module in the entire cooling tower and the uniformity of heat exchange efficiency between the packing modules.

[0329] And using the packing module 1000 of the present embodiment, the above problems can be properly solved.

[0330] (Usage Example 3)

[0331] As the usage example 3 of the packing module 1000 of the present embodiment, in addition to having the advantages of the above usage examples 1 and 2, the heat exchange efficiency of the cooling tower can be further improved, and the cost of the packing module can be significantly reduced, and the convenience of installation and maintenance is further enhanced. The following will be described in detail.

[0332] In the present usage example, as shown in Figure 29 , a cooling tower 3000 is built using the packing module 1000, and the following will only describe the differences between the cooling tower 3000 and the previous embodiments.

[0333] In the cooling tower 3000, unlike the previous ones, each packing module 1000 is provided with a specified installation interval 3999 of 300-600mm between each other, and preferably a closing plate 3998 is provided at the installation seat surface of the packing module 1000 spaced from each other. If the closing plate 3998 is not provided, the support beam as the installation seat of the packing module 1000 can be made to have a plane corresponding to the spacing of the packing module 1000.

[0334] At this time, contrary to the previous usage examples 1 and 2, the second flow path 1000W of the packing module 1000 is preferably made as the air flow path, and the first flow path 1000G is made as the flow path of the sprayed water.

[0335] In this way, the packing modules 1000 can be intentionally spaced when designing the cooling tower 3000, and the installation interval 3999 can allow workers to enter when installing and maintaining the packing modules 1000, so as to move and investigate the state between the packing modules 1000.

[0336] Especially, when installing the packing modules 1000, because the distance of the packing modules 1000 in the stacking direction of the packing modules 1000 is long, the packing modules 1000 are usually divided and stacked only to a specified thickness to form a unit of the packing modules 1000, and the whole row of the packing modules 1000 is formed by arranging each unit in a straight line in the stacking direction of the packing modules 1000 and close to each other. 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 modules 1000 is in a straight line when installed. When the packing modules 1000 do not have the installation interval 3999 between each other in the transverse direction, it is almost impossible to adjust the straightness of each unit 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.

[0337] To this end, according to the present use example, since the installation intervals 3999 are provided between the filler modules 1000 in the lateral direction, when the modules are installed in the stacking direction, the operator can easily adjust the units of the filler modules 1000 by means of the installation intervals 3999. Even if a unit is damaged due to some special accident, the damaged unit can be easily replaced by moving the units before and after it to the position and adding a new unit from the end of the stacking direction of the filler modules 1000, thereby completing the repair.

[0338] When the closing plate 3998 is provided in the installation interval 3999, the closing plate 3998 is preferably removable or erected, so that the closing plate 3998 is inactivated. At this time, since the second flow path 1000W is provided 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.

[0339] (Use Example 4)

[0340] Figure 30 is a schematic view of use example 4. In the present use example, similar to use example 3, intervals are provided between the filler modules 1000 in the lateral direction, but ordinary filler modules F are further filled in the intervals.

[0341] As the ordinary filler module F, it can be any existing filler module. For example, it is the filler module F formed by simply stacking a plurality of filler sheets, which is the most widely used filler module so far. At this time, there is no separated flow path in the filler module F. For each thin sheet-shaped heat exchange space formed by two adjacent filler sheets in the stacking direction, hot water is poured from the upper end opening, and cold air is sucked 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 for heat exchange.

[0342] As described above, in the present use example, the second flow path 1000W is preferably a flow path for spraying hot water, and the first flow path 1000G is an air flow path. In this way, in the present use example, the second flow path 1000W and the filler module F are simultaneously supplied with hot water, and the hot water flowing into the filler module 1000 through the second upper end openings W1, W2 of the filler module 1000 is heat exchanged with the air sucked from the second lower end openings G' of the filler module 1000 in the filler module 1000, on the other hand, the hot water poured into the filler module F is directly contacted with the air sucked from the lower end of the filler module F in the filler module F, and heat exchanged.

[0343] 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 upward from the upper end of the filler module F becomes saturated hot air.

[0344] On the other hand, because of the provision of the second upper end openings W1 and W2, the air resistance in the second flow path 1000W is very large, so actually the amount of air discharged upward from the second upper end opening W of the filler module 1000 is very small, compared to the amount of air passing through the filler module F.

[0345] Therefore, the hot air with low saturation discharged mainly from the first upper end opening G of the filler module 1000, the saturated hot air discharged from the filler module F, and the 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.

[0346] According to the filler module 1000 of the present embodiment, by providing the first upper end opening G in the middle of the top end width direction and the second upper end openings W (W1, W2) on both sides of the first upper end opening G, when the filler module 1000 is used to build the cooling tower 2000, 2100, 3000, 4000, etc., it can be more flexible, and the air passage and the hot water passage can also be flexibly arranged. Especially when the first flow path 1000G connected by 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 fog elimination effect, which is particularly suitable for the situation in winter in northern China.

[0347] However, the filler module 1000 and the cooling tower having the same provided by the present embodiment are not limited to the situation described in the present embodiment.

[0348] In the present embodiment, by making the filler module 1000 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 overlapped filler sheets 1000A and 1000B form an alternating stack, the first flow path 1000G contains the first heat exchange portion 401, the second flow path 1000W contains the second heat exchange portion 402, and the first heat exchange portion 401 and the second heat exchange portion 402 overlap to form the heat exchange portion 400.

[0349] The filler sheet 1000A has a bias portion 1100A that is biased to the front side in the stacking direction at the center of the upper-stage guide portion, and bias portions 1100B that are biased to the rear side in the stacking direction at both sides of the upper-stage guide portion. The filler sheet 1000B has a bias portion 1200A that is biased to the rear side in the stacking direction at the center of the upper-stage guide portion, and bias portions 1200B that are biased to the front side in the stacking direction at both sides of the upper-stage guide portion.

[0350] Thus, by stacking the filler sheet 1000A and the filler sheet 1000B, a first upper-end opening G is formed by the bias portions 1100A, 1100B of the filler sheet 1000A and the filler sheet 1000B that are formed at the center of the upper-stage guide portion. A second upper-end opening W is formed by the bias portions 1200A, 1200B of the filler sheet 1000B and the filler sheet 1000A that are formed at both sides of the upper-stage guide portion.

[0351] In the first flow path 1000G, the first upper-end opening G communicates with the first heat exchange portion 401 of the substantially full-width dimension of the filler module 1000, and in the second flow path 1000W, the second upper-end opening W communicates with the second heat exchange portion 402 of the substantially full-width dimension of the filler module.

[0352] In the present embodiment, a lower-stage guide portion is further provided below the heat exchange portion, and for the first and second flow paths 1000G, 1000W, the lower-stage guide portion is inverted with respect to the first and second upper-stage guide portions 200G, 200W, and includes corresponding bias portions, and a rectifier sheet 1300G', 1300W' that is formed by a first and second lower-end opening, and a slanted flow guide portion that is embedded in the guide portion including the bias portions, and that connects the slanted flow guide portion and the first and second heat exchange portions 401, 402. At this time, the same parts as the rectifier sheets 1300G, 1300W can be used for the rectifier sheets 1300G', 1300W', and they can be inverted.

[0353] The rectifier fins 1300G, 1300W are located in the upper section guide portion of the filler module 1000, and in particular, when guiding the hot water inflow, it is necessary to guide the sprayed hot water to be introduced to the first heat exchange portion 401 or the second heat exchange portion 402 of substantially full width from the first upper end opening G or the second upper end opening W (W1, W2) in the middle of the width direction, so the rectifier fins are bent to form the lower end of the guide groove, and gradually flatten to make the guided fluid evenly distributed on the heat exchange portion surface of the filler sheet 1000A, 1000B. However, for the rectifier fins 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 portion can be removed and only the guide flow path portion formed by bending 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 narrow in the flow path due to the flattened portion of the upper end of the rectifier fins 1300G', 1300W' when flowing out of the filler module 1000, and the impurities in the water are aggregated, and the long-term use is blocked.

[0354] The filler module of the preferred embodiment of the present application and the cooling tower having the same are described in detail above, but those skilled in the art can make various modifications, changes, combinations, etc. on this basis, and these modifications, changes, combinations all fall within the protection scope of the claims of the present application.
