[0027] Next, with reference to the drawings, the preferred implementation modes of the present invention will be described in detail.

[0028]

First implementation mode

[0029]

Packing module 1

[0030] An upper guiding portion 200 and a lower guiding portion 300 are respectively formed at the upper and lower sections of the packing module 1, and a heat exchange section 400 is formed in the middle section.

[0031]

Upper guiding portion 200

[0032] On one side perpendicular to the stacking direction (the left side in the figure), the upper end portion of the packing sheet A is offset toward one side in the stacking direction (the back side in the figure), while the upper end portion of the packing sheet B is offset toward the opposite side (the front side in the figure). Thus, in the stacking direction from the front side to the back side in the figure, the upper end portions of the packing sheets A - B on the left side are in contact with each other, while the upper end portions of the packing sheets B - A on the left side are open to form a first upper opening 210. For the packing module 1, a plurality of first upper openings 210 are arranged side by side in the stacking direction. Thus, the first upper opening 210 communicates with the first flow path R1 formed between the packing sheets B - A.

[0033] At the upper end of the packing piece A on the other side perpendicular to the stacking direction (the right side in the figure), it is offset toward the other side in the stacking direction (the front side in the figure), while the upper end of the packing piece B is offset toward the opposite side (the rear side in the figure), so that the upper right ends of the packing pieces B - A are in contact with each other in the stacking direction from the front side to the rear side in the figure, and the upper right ends of the packing pieces A - B are open to each other to form the second upper opening 220. For the packing module 1, a plurality of second upper openings 220 are arranged side by side in the stacking direction. Thus, the first upper opening 220 communicates with the first flow path R2 formed between the packing pieces A - B.

[0034] In the upper - stage guiding portion 200, a left upper - path rectifying piece 230 is embedded in the first flow path R1 between the first upper opening 210 formed by the packing pieces B - A and the heat - exchange portion 400 surrounded by the packing pieces B - A. The upper end of the left upper - path rectifying piece 230 matches the width of the first upper opening 210, and its width gradually increases from top to bottom, and the lower end corresponds to the width of the heat - exchange portion 400 (the first heat - exchange portion 401 of the first flow path).

[0035] In the present embodiment, the lateral cross - section of the left upper - path rectifying piece 230 perpendicular to the stacking direction is in a folded shape. On both sides in the stacking direction of the folded shape, that is, the back side abuts against the front surface of the packing piece A that holds it, and the front side abuts against the rear surface of the packing piece B that holds it. Thus, in the first flow path R1 that is approximately trapezoidal with a right - angle formed between the first upper opening 210 and the heat - exchange portion 400, a guiding portion is formed that guides from the width of the first upper opening 210 to the full width of the heat - exchange portion 400 with a width approximately that of the packing pieces A and B.

[0036] In the upper - stage guiding portion 200, a right upper - path rectifying piece 240 is embedded in the second flow path R2 between the second upper opening 220 formed by the packing pieces A - B and the heat - exchange portion 400 surrounded by the packing pieces A - B. The upper end of the right upper - path rectifying piece 240 matches the width of the second upper opening 220, and its width gradually increases from top to bottom, and the lower end corresponds to the width of the heat - exchange portion 400 (the first heat - exchange portion 402 of the second flow path).

[0037] In the present embodiment, the lateral cross - section of the right upper - path rectifying piece 240 perpendicular to the stacking direction is in a folded shape. On both sides in the stacking direction of the folded shape, that is, the back side abuts against the front surface of the packing piece B that holds it, and the front side abuts against the rear surface of the packing piece A that holds it. Thus, in the second flow path R2 that is approximately trapezoidal with a right - angle formed between the second upper opening 220 and the heat - exchange portion 400, a guiding portion is formed that guides from the width of the second upper opening 220 to the full width of the heat - exchange portion 400 with a width approximately that of the packing pieces A and B.

[0038]

Lower - stage guiding portion 300

[0039] On one side perpendicular to the stacking direction (the left side in the figure), the lower end portion of the packing sheet A is offset toward one side in the stacking direction (the back side in the figure), while the lower end portion of the packing sheet B is offset toward the opposite side (the front side in the figure). Thus, in the stacking direction from the front side to the back side in the figure, the lower left end portions of the packing sheets A - B are in contact with each other, while the lower left end portions of the packing sheets B - A are open to each other to form a first lower end opening 310. Accordingly, the first lower end opening 310 communicates with the first flow path R1 formed between the packing sheets B - A.

[0040] On the other side perpendicular to the stacking direction (the right side in the figure), the lower end portion of the packing sheet A is offset toward the other side in the stacking direction (the front side in the figure), while the lower end portion of the packing sheet B is offset toward the opposite side (the back side in the figure). Thus, in the stacking direction from the front side to the back side in the figure, the lower left end portions of the packing sheets B - A are in contact with each other, while the lower left end portions of the packing sheets A - B are open to each other to form a second lower end opening 320. Accordingly, the first lower end opening 320 communicates with the first flow path R2 formed between the packing sheets A - B.

[0041] In the lower guide portion 300, a lower left path rectifying fin 330 is embedded in the first flow path R1 between the first lower end opening 310 formed by the packing sheets B - A and the heat exchange portion 400 surrounded by the packing sheets B - A. The lower end of the lower left path rectifying fin 330 matches the width of the first lower end opening 310, and the width gradually increases from bottom to top, and the upper end corresponds to the width of the heat exchange portion 400.

[0042] In the present embodiment, the lateral cross - section of the lower left path rectifying fin 330 perpendicular to the stacking direction is in a bent shape. The back side of the bent shape abuts against the front surface of the packing sheet A, and the front side abuts against the back surface of the packing sheet B. Thus, in the first flow path R1 in the shape of an approximately inverted right - angled trapezoid formed between the first lower end opening 310 and the heat exchange portion 400, a guiding portion is formed that guides from the width of the first lower end opening 310 to the full width of the heat exchange portion 400 with a width approximately that of the packing sheets A and B.

[0043] In the lower guide portion 300, a lower right path rectifying fin 340 is embedded in the second flow path R2 between the second lower end opening 320 formed by the packing sheets A - B and the heat exchange portion 400 surrounded by the packing sheets A - B. The lower end of the lower right path rectifying fin 340 matches the width of the second lower end opening 320, and the width gradually increases from top to bottom, and the lower end corresponds to the width of the heat exchange portion 400.

[0044] In the present embodiment, the lateral cross-section of the lower right rectifying sheet 340 perpendicular to the stacking direction is bent, and the bent dorsal side abuts against the front surface of the filler sheet B, and the front side abuts against the rear surface of the filler sheet A. Thus, in the second flow path R2 in the shape of an approximately inverted right trapezoid formed between the second lower end opening 320 and the heat exchange section 400, a guiding section is formed that guides the width from the second lower end opening 320 to the full width of the heat exchange section 400, which is approximately the width of the filler sheets A and B.

[0045] The filler module 1 is formed by alternately stacking the filler sheet A and the filler sheet B, and the first flow path R1 and the second flow path R2 that are isolated from each other and alternately stacked are formed in the filler module 1. Hereinafter, the configurations of the first flow path R1 and the second flow path R2 will be described in detail.

[0046]

Unit of the first flow path R1

[0047] As shown in the figure, the first flow path R1 includes, from top to bottom, the first upper end opening 210 located on the left side of the upper end of the filler module 1; the upper left guiding section 201 of the upper guiding section 200 filled and supported by the upper left rectifying sheet 230 between the filler sheets B and A; the first heat exchange section 401 in the shape of a flat cavity formed between the filler sheets B - A in the stacking direction at the heat exchange section 400; the lower left guiding section 301 of the lower guiding section 300 filled and supported by the lower left rectifying sheet 330 between the filler sheets B and A; and the first lower end opening 310 located on the left side of the lower end of the filler module 1.

[0048] Thus, in the present embodiment, a unit of the first flow path R1 in the shape of a flat cavity is formed between the adjacent filler sheet B and the filler sheet A, and the first upper end opening 210 serving as the upper end opening thereof and the first lower end opening 310 serving as the lower end opening are located on the same side perpendicular to the stacking direction.

[0049]

Unit of the second flow path R2

[0050] As shown in the figure, the second flow path R2 includes, from top to bottom, a second upper end opening 220 located on the upper right side of the upper end of the packing module 1; a right upper guiding part 202 of the upper guiding part 200 filled and supported by a right upper flow rectifying piece 240 between the packing pieces A and B; a second heat exchange part 402 in the form of a flat cavity formed between the packing pieces A and B in the stacking direction at the heat exchange part 400; a right lower guiding part 302 of the lower guiding part 300 filled and supported by a right lower flow rectifying piece 340 between the packing pieces A and B; and a second lower end opening 320 located on the lower right side of the lower end of the packing module 1.

[0051] Thus, in this embodiment, a unit of the first flow path R1 in the form of a flat cavity is formed between adjacent packing pieces A and B, and the second upper end opening 220 as the upper end opening thereof and the second lower end opening 320 as the lower end opening thereof are located on the same side perpendicular to the stacking direction.

[0052]

Heat exchange part 400

[0053]

Upper and lower end openings of the flow path

[0054] In this embodiment, as shown in the figure, the first upper end opening 210 is formed on the left side. Since the upper left end part of the packing piece A is offset backward in the figure, and the upper left end part of the packing piece B is offset forward in the opposite direction in the figure, the upper left end parts of the packing pieces A - B are in contact with each other, while the upper left end parts of the packing pieces B - A are open to each other. Thus, a strip-shaped opening with the upper left end parts of the packing pieces B - A open to each other is formed, and through the upper left end parts of the contacting packing pieces A - B, they are arranged side by side in the stacking direction to form a complete first upper end opening 210. Without considering the thickness of the packing pieces, it is equivalent to forming an open first upper end opening 210 in the entire area on one side (the left side in the figure) perpendicular to the stacking direction at the upper end of the packing module 1.

[0055] Similarly, the second upper end opening 220 is formed on the right side. Contrary to the first upper end opening 210, the upper right end of the packing sheet B is offset toward the back side in the figure, while the upper right end of the packing sheet A is offset toward the front side in the opposite figure. Thus, the upper right ends of the packing sheets B - A are in contact with each other, while the upper right ends of the packing sheets A - B are open to each other. As a result, a strip-shaped opening with the upper right ends of the packing sheets A - B open to each other is formed. Through the upper right ends of the contacting packing sheets B - A, they are arranged side by side in the stacking direction to form a complete second upper end opening 220. Without considering the thickness of the packing sheets, it is equivalent to forming an open second upper end opening 220 in the entire area on the other side (right side in the figure) perpendicular to the stacking direction at the upper end of the packing module 1.

[0056] On the other hand, for the first and second upper end openings 210 and 220 formed at the lower end edge and arranged side by side in a direction perpendicular to the stacking direction.

[0057] In the present embodiment, as shown in the figure, the first lower end opening 310 is formed on the left side. Since the lower left end of the packing sheet A is offset toward the back side in the figure, while the lower left end of the packing sheet B is offset toward the front side in the opposite figure, the lower left ends of the packing sheets A - B are in contact with each other, while the lower left ends of the packing sheets B - A are open to each other. As a result, a strip-shaped opening with the lower left ends of the packing sheets B - A open to each other is formed. Through the lower left ends of the contacting packing sheets A - B, they are arranged side by side in the stacking direction to form a complete first lower end opening 310. Without considering the thickness of the packing sheets, it is equivalent to forming an open first lower end opening 310 in the entire area on one side (left side in the figure) perpendicular to the stacking direction at the lower end of the packing module 1.

[0058] Similarly, the second lower end opening 320 is formed on the right side. Contrary to the first lower end opening 310, the lower right end of the packing sheet B is offset toward the back side in the figure, while the lower right end of the packing sheet A is offset toward the front side in the opposite figure. Thus, the lower right ends of the packing sheets B - A are in contact with each other, while the lower right ends of the packing sheets A - B are open to each other. As a result, a strip-shaped opening with the lower right ends of the packing sheets A - B open to each other is formed. Through the lower right ends of the contacting packing sheets B - A, they are arranged side by side in the stacking direction to form a complete second lower end opening 320. Without considering the thickness of the packing sheets, it is equivalent to forming an open second lower end opening 320 in the entire area on the other side (right side in the figure) perpendicular to the stacking direction at the lower end of the packing module 1.

[0059]

Openings of the flow path

[0060] As described above, the first flow path R1 is at the upper end of the filler module 1. It forms a first upper opening 210 in the entire left area perpendicular to the stacking direction. At the first upper opening 210, the portion where the left upper ends of the filler sheets A - B are in contact with each other divides the first flow path R1 into multiple units. In the upper left guiding portion 201, after passing downward through the portion where the left upper ends of the filler sheets A - B are in contact with each other, the units of the first flow path R1 are separated from each other in the stacking direction. On the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases in the direction perpendicular to the stacking direction to approximately the width of the filler sheets A and B, forming a flattened shape, that is, the thickness decreases and the width increases. Then, the units enter the first heat exchange portion 401 of the flattened heat exchange space defined by the filler sheets B - A in the heat exchange portion 400 from the upper guiding portion 200.

[0061] When continuing downward from the heat exchange portion 400 to the lower guiding portion 300, contrary to the situation in the upper guiding portion 200, the units of the first flow path R1 change from a flattened shape with approximately the width of the filler sheets A and B downward. On the one hand, the size gradually increases in the stacking direction, and on the other hand, the size gradually decreases in the direction perpendicular to the stacking direction to the width of the second lower opening 220, that is, the thickness increases and the width decreases. And in the lower left guiding portion 301, they converge at the portion where the left lower ends of the filler sheets A - B are in contact with each other and reach the first lower opening 310.

[0062] Thus, in the first flow path R1, in the entire flow path from the first upper opening 210 through the upper guiding portion 200, the heat exchange portion 400, the lower guiding portion 300 to the first lower opening 310, theoretically, the cross-sectional area of the flow path remains approximately unchanged.

[0063] For the second flow path R2, its structure is rotationally symmetric to that of the first flow path R1, which will be further described in detail below.

[0064] As described above, the second flow path R2 is at the upper end of the filler module 1. It forms a second upper opening 210 in the entire right area perpendicular to the stacking direction. At the second upper opening 210, the portion where the right upper ends of the filler sheets B - A are in contact with each other divides the second flow path R2 into multiple units. In the upper right guiding portion 202, after passing downward through the portion where the right upper ends of the filler sheets B - A are in contact with each other, the units of the first flow path R1 are separated from each other in the stacking direction. On the one hand, the size gradually decreases in the stacking direction, and on the other hand, the size gradually increases in the direction perpendicular to the stacking direction to approximately the width of the filler sheets A and B, forming a flattened shape, that is, the thickness decreases and the width increases. Then, the units enter the second heat exchange portion 402 of the flattened heat exchange space defined by the filler sheets A - B in the heat exchange portion 400 from the upper guiding portion 200.

[0065] When continuing downward from the heat exchange section 400 to the lower guide section 300, contrary to the situation in the upper guide section 200, the unit of the second flow path R2 is flat in the width of the approximate packing sheets A and B and faces downward. On the one hand, the dimension in the stacking direction gradually increases, and on the other hand, the dimension perpendicular to the stacking direction gradually decreases to the width of the second lower end opening 220, that is, the thickness increases and the width decreases, and converges at the lower right guide section 302 at the part where the right lower end portions of the packing sheets B - A are in contact with each other and reaches the second lower end opening 320.

[0066] Thus, in the second flow path R2, in the entire flow path from the second upper end opening 220 through the upper guide section 200, the heat exchange section 400, the lower guide section 300 to the second lower end opening 320, theoretically, the cross-sectional area of the flow path remains substantially unchanged.

[0067] As described above, in the present embodiment, as the first and second upper end openings 210 and 220 of the first and second flow paths R1 and R2, the sum of the opening areas is consistent with the sum of the cross-sectional areas of the respective parts from top to bottom. Similarly, as the first and second lower end openings 310 and 320 of the first and second flow paths R1 and R2, the sum of the opening areas is consistent with the sum of the cross-sectional areas of the respective parts from top to bottom, that is, the opening areas at the upper and lower ends of the packing module 1 are consistent with the horizontal cross-sectional area of the packing module 1, thereby greatly improving the fluid passing amount and passing efficiency of the respective flow paths R1 and R2, reducing the resistance of the packing module 1, which will be further described in detail later.

[0068]

Straightening fins

[0069] In addition, in the present embodiment, the first upper opening 210 and the second upper opening 220, which are the upper openings of the first and second flow paths R1 and R2, are arranged side by side in a direction perpendicular to the stacking direction and have substantially the same width. Thus, the left upper path rectifying fins 230 and the right upper path rectifying fins 240, which are respectively located in the left upper segment guiding portion 201 and the right upper segment guiding portion 202, have substantially the same configuration of the receiving space and are arranged in a rotationally symmetric manner. Therefore, the same components can be used to form the left upper path rectifying fins 230 and the right upper path rectifying fins 240.

[0070] Similarly, the first lower opening 310 and the second lower opening 320, which are the lower openings of the first and second flow paths R1 and R2, are arranged side by side in a direction perpendicular to the stacking direction and have substantially the same width. Thus, the left lower path rectifying fins 330 and the right lower path rectifying fins 340, which are respectively located in the left lower segment guiding portion 301 and the right lower segment guiding portion 302, have substantially the same configuration of the receiving space and are arranged in a rotationally symmetric manner. Therefore, the same components can be used to form the left lower path rectifying fins 330 and the right lower path rectifying fins 340.

[0071] Furthermore, in the present embodiment, by making the heights of the upper segment guiding portion 200 and the lower segment guiding portion 300 substantially the same, the configurations of the receiving spaces of the respective rectifying fins 230, 240, 330, and 340 are made substantially the same. Thus, the same components can be used to form the left upper path rectifying fins 230, the right upper path rectifying fins 240, the left lower path rectifying fins 330, and the right lower path rectifying fins 340. In this way, when manufacturing the packing module 1, only the packing sheet A, the packing sheet B, and the common rectifying fins are required, significantly reducing the production cost of the packing module 1 and significantly improving the assembly efficiency.

[0072] In this embodiment, the same filler sheets A and B as those in the first embodiment can be used. In the first embodiment, the upper left guiding portion 201, the upper right guiding portion 202, the lower left guiding portion 301, and the lower right guiding portion 302 are respectively provided with the upper left rectifying sheet 230, the upper right rectifying sheet 240, the lower left rectifying sheet 330, and the lower right rectifying sheet 340. The upper left guiding portion 201 and the lower left guiding portion 301 are both located on the same side of the filler module 1 (the left side in the first embodiment), and the upper right guiding portion 202 and the lower right guiding portion 302 are both located on the other same side of the filler module 1 (the right side in the first embodiment). That is, the fluid flowing into / introduced into the filler module 1 from one side (left side) in the width direction of the filler module 1 forms a flow path R1 of substantially the full width of the filler module 1 in the heat exchange portion 400; and the fluid flowing into / introduced into the filler module 1 from the other side (right side) in the width direction of the filler module 1 forms a flow path R2 of substantially the full width of the filler module 1 in the heat exchange portion 400. The thickness of R1 and R2 in the stacking direction is half of the thickness of each opening in the stacking direction, and the sum of the respective thicknesses of R1 and R2 is equivalent to half of the thickness of the filler module 1 in the stacking direction. Therefore, a state of inflow and outflow on the same side is formed. That is, if hot water flows in from the first upper opening 210 at the upper left end, the filler module 1 flows out from the first lower opening 310 at the lower left end. If cold air is introduced from the first lower opening 310 at the lower left end, the filler module 1 flows out from the first upper opening 210 at the upper left end, becoming the first flow path R1; the same is true for the second upper opening 220 and the second lower opening 320, which are the upper and lower end openings on the right side, except that the flowing fluid is different from that on the left side, becoming the second flow path R2. Of course, the filler module 1 can also be the same as the conventional filler module, and hot water is simultaneously sprayed into the first and second upper openings 210 and 220, and cold air is simultaneously sucked from the first and second lower openings 310 and 320 to form direct contact heat exchange between the hot water and the cold air flowing in the reverse direction in the flow path. However, when the first flow path R1 and the second flow path R2 flow in different fluids respectively as described above, the exhausted hot air after heat exchange has a low saturation humidity, avoiding fog formation.

[0073] Of course, the first upper opening 210 and the first lower opening 310, which are the upper and lower end openings of the first flow path R1, can also be respectively arranged on different sides of the left and right of the filler module; similarly, the second upper opening 220 and the second lower opening 320, which are the upper and lower end openings of the second flow path R2, are also respectively arranged on different sides of the left and right of the filler module. It has no substantial impact on the function of the filler module 1 having two flow paths R1 and R2 and the upper and lower end openings separated by the filler sheets A and B, and belongs to an equivalent embodiment to the above first embodiment.

[0074]

Second Embodiment

[0075] As Figures 10 - 12 shown, by only providing the flow rectifying sheets 230 and 330 in the first flow path R1, in the first flow path R1, the spray water flowing into the filler module 1' from the left side of the arrow shown in the figure of the filler module 1' along the stacking direction through the first upper end opening 210, that is, a part of the width of the upper opening, is guided by the flow rectifying sheet 230 in the upper left section guiding portion 201 to the substantially full width range of the first heat exchange portion 401, and effectively forms a water film on the wall surfaces of the filler sheets A and B on both sides of the first flow path R1. Then it is guided by the flow rectifying sheet 330 in the lower left section guiding portion 301 to the first lower end opening 310 arranged along the stacking direction on the left side of the arrow shown in the figure of the filler module 1', and flows out from a part of the width of the lower opening of the filler module 1'.

[0076] On the other hand, the cold air introduced into the filler module 1' through the second lower end opening 320, that is, a part of the width of the lower opening, arranged along the stacking direction from the right side of the arrow shown in the figure of the filler module 1' via the second flow path R2 enters the lower right section guiding portion 302, and based on the flow property of the gas fluid itself, the lower section guiding portion 302 gradually restricts the thickness of the flow path in the stacking direction and gradually expands the width of the flow path to the substantially full width range of the second heat exchange portion 402, and effectively exchanges heat with the hot water attached to the wall portion of the first heat exchange portion 401 across the filler sheets A and B. Then in the upper right section guiding portion 202, the width of the flow path is gradually restricted to the second upper end opening 220 arranged along the stacking direction, that is, a part of the width of the upper opening, and the thickness of the flow path in the stacking direction is gradually expanded to 2d, and is led out from the second upper end opening of the filler module 1'.

[0077] It can be seen that, compared with the filler module 1 of the first embodiment of the present invention, in this embodiment, by removing the flow rectifying sheets in the upper right guiding part 202 and the lower right guiding part 302 of the second flow path R2 and using the second flow path R2 only as a cold air flow path, the cold air attracted into the second flow path R2 can obtain as small a wind resistance as possible. Moreover, since the air flow is not affected by the gravity when water flows, even without setting flow rectifying sheets, when ensuring the same air flow rate as in the above first embodiment passes through the second flow path R2, a cooling efficiency approximately the same as that of the filler module 1 of the first embodiment can be obtained. However, at this time, since there are no flow rectifying sheets 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 electric energy can be effectively saved. And, since the filler module 1' in this embodiment can obtain a smaller wind resistance, it is more suitable for cooling towers such as hyperbolic cooling towers that do not have a fan and adopt a passive air suction method.

[0078] In this embodiment, preferably, 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 width direction of the filler module. Furthermore, through the arrangement of the filler sheets A and B, a good water isolation structure can be formed to prevent the water in the first flow path R1 provided with the upper left flow rectifying sheet 230 and the lower left flow rectifying sheet 330 from invading the air flow path of the second flow path R2 through the gaps. The following is a detailed description.

[0079] Furthermore, in this embodiment, as Figure 11 shown, the upper end portion of the filler sheet A of the filler module 1' is on the left side of the part where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the side of the first upper end opening 210, and is offset backward by a distance of d / 2 from the base position O of the heat exchange part 400 of the filler sheet A, A thus forming the rear half part of the first upper end opening 210 constituted by the filler sheet A. Furthermore, at the left end edge of the filler sheet A, a left sealing edge part 215A is formed at a position offset forward by a distance d from the rear half part of the first upper end opening 210, that is, offset forward by d / 2 from the base position O of the heat exchange part 400 of the filler sheet A. A The left sealing edge part 215A extends linearly in the up and down direction.

[0080] Furthermore, at the upper end portion of the filler sheet A, on the right side of the part where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the side of the second upper end opening 220, it is offset forward by a distance of d / 2, thus forming the front half part of the second upper end opening 210 of the second flow path R2 at the rear side constituted by the filler sheet A.

[0081] Further, the upper end portion of the filler sheet B adjacent to the filler sheet A on the front side in the stacking direction is located on the left side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the side of the first upper end opening 210, and is offset forward by a distance of d / 2 from the base position O of the heat exchange portion 400 of the filler sheet B, thereby forming the front half of the first upper end opening 210 formed by the filler sheet B. Further, at the left end edge of the filler sheet B, a position offset backward by a distance d from the front half of the first upper end opening 210 is formed, that is, offset backward by d / 2 from the base position O of the heat exchange portion 400 of the filler sheet B, to form the left sealing edge portion 215B. The left sealing edge portion 215B extends linearly in the vertical direction. B Furthermore, at the upper end portion of the filler sheet B, on the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the side of the second upper end opening 220, it is offset backward by a distance of d / 2, thereby forming the rear half of the second upper end opening 210 of the second flow path R2 on the front side formed by the filler sheet B. B Thus, when the filler sheet A and the filler sheet B adjacent to its front side are assembled in contact with each other, when the first upper end opening 210 is completely surrounded by the rear half of the first upper end opening 210 of the filler sheet A and the front half of the first upper end opening 210 of the filler sheet B adjacent to the front side at the upper end edges of the left side portions of the filler sheet A and the filler sheet B, and on the left side of the first upper end opening 210, the left sealing edge portion 215A of the filler sheet A and the left sealing edge portion 215B of the filler sheet B are juxtaposed with each other from top to bottom.

[0082] Thus, for the first flow path R1 formed by the filler sheet A and the filler sheet B adjacent to its front side, it has a flow inlet with a thickness of 2d, that is, the first upper end opening 210, and its left sealing edge 215 is formed by the combination of the left sealing edge portion 215A and the left sealing edge portion 215B that are juxtaposed relative to each other. Its left sealing edge 215 can easily form a sealing structure when performing joint sealing. When the first flow path R1 is used as the flow path for hot water spraying, since the hot water is sprayed into the first upper end opening 210 arranged in the front and back on the left side of the filler module 1', when guiding the hot water into the heat exchange portion 400, the hot water is not likely to seep out from the left sealing edge 215.

[0083] On the other hand, after guiding the hot water from the first upper end opening 210 to the heat exchange portion 400, the water overflows along the rear wall surface of the filler sheet B on the front and back sides and the front wall surface of the filler sheet A under its own gravity in the heat exchange portion 400, and does not easily invade the right sealing edge of the filler module 1'. Therefore, the sealing requirement for the right sealing edge is significantly reduced.

[0084] Furthermore, at the upper end portion of the filler sheet B, on the right side of the portion where the first upper end opening 210 and the second upper end opening 220 are connected, that is, on the side of the second upper end opening 220, it is offset backward by a distance of d / 2, thereby forming the rear half of the second upper end opening 210 of the second flow path R2 on the front side formed by the filler sheet B.

[0085] On the other hand, after guiding the hot water from the first upper end opening 210 to the heat exchange portion 400, the water overflows along the rear wall surface of the filler sheet B on the front and back sides and the front wall surface of the filler sheet A under its own gravity in the heat exchange portion 400, and does not easily invade the right sealing edge of the filler module 1'. Therefore, the sealing requirement for the right sealing edge is significantly reduced.

[0086] Specifically, in the present embodiment, for the lower guiding portion 300, if the lower guiding portion 300 is rotated 180° about a horizontal axis perpendicular to the stacking direction, its structure is the same as that of the upper guiding portion 200. For the lower guiding portion 300, similar to the structure of the upper guiding portion 200, the lower edges of the filler sheet A and the adjacent filler sheet B in front of it are offset, so that continuous left sealing edges 215A and 215B are formed from top to bottom along the left edge of the filler sheet A and the filler sheet B, including the left edge of the heat exchange portion 400, thereby effectively preventing water from seeping out from the left sealing edge 215, especially preventing water from seeping out from the left sealing edge 215 at the part of the upper guiding portion 200 and the lower guiding portion 300.

[0087] Furthermore, in the present embodiment, for the sealing edge 215 formed by the left sealing edges 215A and 215B, any joining method can be used. Considering the convenience of assembly, it is preferably to join the sealing edge 210 by pressure welding. This is because when assembling the filler sheets A and B and the rectifying sheets 230 and 330 using equipment, only by aligning the adjacent filler sheets B in the front-rear direction, at this time, since the right-side parts of the upper and lower edges of the filler sheets A and B are offset and close to each other, thus, in this state, operating the pressure welding equipment to weld the sealing edge 215 and the right-side parts of the upper and lower edges of the filler sheet B-A can complete the welding operation of the filler sheet B-A.

[0088] Thereby, after inserting the rectifying sheets 230 and 330 between the filler sheets B-A and welding the sealing edge 215 and the right-side parts of the upper and lower edges of the filler sheet B-A, the filler sheets B-A in the front-rear direction of the stacking direction can form a module with very high structural stability with each other, and then the modules formed by multiple filler sheets B-A are combined and pasted in the stacking direction. Because 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 modules of the filler sheets B-A into the filler module 1' can be improved.

[0089] In the drawings of the present embodiment, for the sake of the assembly process and processing convenience, the same structure as that of the left sealing edge 215 is not applied to the right sealing edge. However, this does not limit the structure of the right sealing edge. Of course, the same structure as that of the left sealing edge 215 can also be applied to the right sealing edge.

[0090]

Third Embodiment

[0091] In this embodiment, the upper edge of the upper left rectifying piece 230 and the upper edge of the upper right rectifying piece 240 are respectively lower than the first upper opening 210 and the second upper opening 220, that is, the upper edges of the upper left rectifying piece 230 and the upper right rectifying piece 240 are respectively located inside the first upper opening 210 and the second upper opening 220.

[0092] Similarly, the upper edge of the lower left rectifying piece 330 and the upper edge of the lower right rectifying piece 340 are respectively higher than the first lower opening 310 and the second lower opening 320, that is, the lower edges of the lower left rectifying piece 330 and the lower right rectifying piece 340 are respectively located inside the first lower opening 310 and the second lower opening 320.

[0093] That is to say, in this embodiment, the opening side end portions of the rectifying pieces 230, 240, 330, and 340 are respectively located at a specified distance h inside the corresponding upper and lower openings 210, 220, 310, and 320. In Figure 13 , 14 only the upper left rectifying piece 230 is shown as an example, and the other rectifying pieces 240, 330, and 340 can be set in the same way.

[0094] When laminating the packing sheets A and B, at the upper left guiding portion 201, since the packing sheet A is offset to the rear side in the laminating direction and the packing sheet B is offset to the front side in the laminating direction, the left upper edges of the two are joined together at the edge of the first upper opening 210.

[0095] Since the rectifying piece 230 embedded in the upper left guiding portion 201 is located inside the first upper opening 210, the upper edge of the packing sheets A - B at the first upper opening 210 in the laminating direction is avoided, and a distance h is maintained. Thus, the avoidance area can be subjected to welding treatment with a heating jig, thereby forming a welding track L.

[0096] In the first and second embodiments, the rectifying piece 230 is not retracted into the first upper opening 210. When performing the welding treatment, due to the interference of the rectifying piece folded and arranged at the end face of the first upper opening 210, only intermittent welds can be formed corresponding to the folding of the rectifying piece 230. For the left upper edges of the packing sheets A - B, only caulking can be used for sealing after being joined together.

[0097] In contrast, in the present embodiment, by retracting the rectifying sheet into the first upper end opening 210, this avoidance area can be utilized to perform continuous pressure welding on the left upper edge of the packing sheet A-B.

[0098] In this way, on the one hand, the connection strength of the left upper edge of the packing sheet A-B is improved, so that the overall strength of the packing module 1" can be significantly improved even after multiple layers of the packing sheets A and B are stacked.

[0099] On the other hand, and more importantly, when the first flow path R1 on the left side is used as a hot water spray flow path and the second flow path R2 on the right side is used as an air flow path, the inside of the left upper joint of the packing sheet A-B forming the first upper end opening 210 is communicated with the second flow path R2. By welding and joining this joint, the water tightness performance can be effectively improved, and the situation of glue detachment and water leakage caused by aging over the years can be avoided.

[0100] Furthermore, in the present embodiment, as shown in the second embodiment, by making the first lower end opening also located on the left side of the packing module 1" and respectively forming continuous edge sealing portions 215A and 215B on the left edges of the packing sheet A and the packing sheet B, when the first flow path R1 is used as a hot water spray flow path, the probability of leakage from the upper end to the second flow path can be minimized; the left side can also be sealed by welding without leakage.

[0101] For the right side, since the first flow path R1 guides hot water from a part of the width on the left side, to the substantially full width of the heat exchange portion, and then back to a part of the width on the left side and flows out from the first lower end opening 310, due to the action of gravity, it is very difficult for the hot water to overflow from the right edge. Therefore, for the right side edge sealing, simple methods such as fitting connection, bonding, and spot welding by means of convex-concave joints can be adopted.

[0102] Of course, without considering a small increase in cost, the right side edge sealing can also adopt a method corresponding to the left side edge sealing. Of course, the right edge sealing can also be formed by offsetting the right edge of the heat exchange portion 400 of the packing sheets A and B in the same direction as the left edge. Thus, the first flow path can be completely sealed.

[0103] In this embodiment, as an example, only the configuration of the upper left rectifying fin 230 and the first upper end opening 210 in the upper left guiding part 201 is described. The same structure can also 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 rectifying fins 240, 330, 340. Thereby, the overall strength of the packing module 1" can be improved. In particular, for the upper and lower end faces of the packing module 1" formed with the upper and lower end openings 210, 220, 310, 320 arranged in parallel, the strength will be greatly enhanced. In this way, for the transportation, operation handling, installation operation, and daily operation of the packing module 1", the firmness, reliability, and durability will all be greatly improved.

[0104]

Fourth Embodiment

[0105] The packing sheet A is configured such that an upper left offset part offset backward is provided on the left side of the upper end part; an upper right offset part offset forward is provided on the right side of the upper end part; a lower left offset part offset backward is provided on the left side of the lower end part; a lower right offset part offset forward is provided on the right side of the lower end part, and the adjacent packing sheet B can be arranged in a manner of being flipped 180° around the horizontal axis of the main body part of the packing sheet A.

[0106] Thereby, the upper right offset part of the packing sheet A is juxtaposed with the lower right offset part of the packing sheet B located on the front side in the stacking direction; the lower right offset part of the packing sheet A is juxtaposed with the upper right offset part of the packing sheet B, so that a first upper end opening 210 is formed between the upper left offset part of the packing sheet A and the lower left offset part of the packing sheet B, and a first lower end opening 310 is formed between the lower left offset part of the packing sheet A and the upper left offset part of the packing sheet B. The first upper end opening 210 and the first lower end opening 310 are respectively communicated with a first heat exchange part 401 formed between the main body part of the packing sheet A and the main body part of the packing sheet B in the up and down direction, thereby forming a first flow path R1.

[0107] The upper left offset portion of the packing sheet A is juxtaposed with the lower left offset portion of the packing sheet B located at the rear side in the stacking direction; the lower left offset portion of the packing sheet A is juxtaposed with the upper left offset portion of the packing sheet B, so as to form a second upper end opening 220 between the upper right offset portion of the packing sheet A and the lower right offset portion of the packing sheet B, and a second lower end opening 320 is formed between the lower right offset portion of the packing sheet A and the upper right offset portion of the packing sheet B. 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 packing sheet A and the body portion of the packing sheet B in the up-down direction, thereby forming a second flow path R2.

[0108] Furthermore, a left upper path flow rectifying sheet 230 with a gradually increasing width and a gradually decreasing thickness from the first upper end opening 310 to the first heat exchange portion 401 is provided between the upper left offset portion of the packing sheet A and the lower left offset portion of the packing sheet B.

[0109] A lower left path flow rectifying sheet 330 with a gradually increasing width and a gradually decreasing thickness from the first lower end opening 310 to the first heat exchange portion 401 is provided between the lower left offset portion of the packing sheet A and the upper left offset portion of the packing sheet B.

[0110] Similarly, a right upper path flow rectifying sheet 240 with a gradually increasing width and a gradually decreasing thickness from the second upper end opening 220 to the second heat exchange portion 402 is provided between the upper right offset portion of the packing sheet A and the lower right offset portion of the packing sheet B.

[0111] A lower right path flow rectifying sheet 340 with a gradually increasing width and a gradually decreasing thickness from the second lower end opening 320 to the second heat exchange portion 402 is provided between the lower right offset portion of the packing sheet A and the upper right offset portion of the packing sheet B.

[0112] On this basis, if, as in the second embodiment, the left edge of each packing sheet A is offset forward to form a linear sealing edge portion 215A, the sealing edge portion of the packing sheet A and the sealing edge portion 215B of the packing sheet B located at the front side in the stacking direction are juxtaposed with each other.

[0113] The sealing edge portion 215A of the packing sheet A and the sealing edge portion 215B of the packing sheet B located at the front side in the stacking direction are juxtaposed with each other and are welded and joined to form a left sealing edge 215.

[0114] Thus, according to this embodiment, the number of components can be further reduced. When assembling the packing module using the packing sheets, it is only necessary to stack the non-flipped packing sheet A and the packing sheet B flipped 180° in sequence.

[0115]

Cooling tower 1

[0116] The bottom layer of the cooling tower 10 is an air intake layer 101, and a plurality of dampers 102 are arranged around the air intake layer 101. A packing layer 103 is arranged above the air intake layer 101, and the packing layer 103 is arranged in a matrix shape on a horizontal plane by a plurality of packing modules 1. A spraying part 104 is arranged above the packing layer 103, and the spraying part 104 sprays the hot water to be treated to each packing module 1 of the packing layer 103. A partition 105 extending along the stacking direction of the packing module 1 is roughly vertically arranged in the area between the spraying part 104 and the packing layer 103, and a plurality of partition spaces 105a and 105b are surrounded by the partition 105 and the top surface of the packing module 1, wherein the partition space 105a is used as a spraying space for spraying hot water, and the partition space 105b is used as an air induction space for sucking gas from bottom to top. The spray space 105a and the air entrainment space 105b are alternately arranged in a direction perpendicular to the stacking direction of the matrix composed of the filling modules 1, and each partition 105 is arranged at the intersection of the first upper end opening 210 and the second upper end opening 220 of the filling module 1, thereby separating the first flow path R1 and the second flow path R2 connected to the first upper end opening 210 and the second upper end opening 220.

[0117] Above the spray section 104 is the exhaust layer 106, and above the exhaust layer 106 is an exhaust port 108 provided with a fan 107. The fan 107 draws air upward, so that cold air enters the air intake layer 101 from the damper 102 in the lower layer of the cooling tower 10, passes upward through each packing module 1 of the packing layer 103, passes through the spray space 105a and the inducing space 105b respectively, is further mixed in the exhaust layer 106, and is discharged upward through the exhaust port 108.

[0118] On the other hand, the hot water to be treated sprayed from the spraying part 104 to each packing module 1 of the packing layer 103 is cooled by each packing module 1 and falls to the bottom surface of the air inlet layer 101. The cooled water is recovered through the collection equipment for recycling in the factory.

[0119] Working status 1: As described above, the cooling tower 10 is set to the winter working state. At this time, the hot water to be treated sprayed from the spray part 104 is confined in the spray space 105a and enters one of the two flow paths of the packing module 1. In this embodiment, since the partition 105 is arranged at the intersection of the first upper end opening 210 and the second upper end opening 220 relative to the packing module 1, the first and second flow paths R1 and R2 adjacent to each other between two adjacent packing modules 1 both form water flow paths, and the outer flow paths R1 and R2 are respectively adjacent to the second and first flow paths adjacent to both sides, and both form air flow paths.

[0120] In the water flow path, the sprayed water flows into the packing module 1. Via the upper guiding part 200, in the heat exchange part 400, it forms a water film that adheres to the side walls of the flat space in the substantially full width of the packing module 1 in the stacking direction within a flat space. The adjacent flow paths on both sides in the stacking direction serve as air flow paths, and heat exchange is performed with the hot water in the water flow path across the walls of the packing sheets A and B.

[0121] When the cooling tower 10 operates in winter, the air inhaled from below the packing module 1 into the air flow path is dry cold air with a low air temperature and low water content. When heat exchange occurs with the hot water in the air flow path passing through the packing module 1, since the heat exchange is completely completed in independent flow paths across the packing sheets A and B, when it is discharged from above the packing module 1, the temperature rises, but the water content at this time does not change, that is, dry hot air is formed.

[0122] On the other hand, because there is hot water sprayed down from the upper spraying part 104 in the water flow path, the air attracted by the fan 107 in the water flow path is subject to a large resistance. Therefore, the air flow rate relative to the air flowing through the air flow path is very small, usually only a fraction. And the air flowing through the air flow path will form hot saturated air, that is, humid hot air.

[0123] 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. Due to the small amount of humid hot air, unsaturated hot air is formed after mixing with the dry hot air. After being discharged to the atmosphere through the fan 107 and the air outlet 108, the unsaturated hot air is gradually cooled, and the amount of water precipitated is small, greatly reducing the amount of fog formed.

[0124] In this embodiment, by switching the spraying part 104, the spraying space 105a and the air intake space 105b can be flexibly switched, that is, stopping spraying hot water into the spraying space 105a and spraying hot water into the air intake space 105b. In this way, the functions of the spraying space 105a and the air intake space 105b can be swapped. On the one hand, it can ensure the normal operation of the cooling tower 10, and on the other hand, it can effectively clean and maintain the flow paths R1 or R2 of the packing module 1 connected to the air intake space 105b. Thus, when cleaning and maintaining the cooling tower 10, it does not affect the normal operation of the cooling tower 10.

[0125] Operating state two: When operating in the summer, by adjusting the spraying part 104, hot water can be sprayed into the air intake space 105b in the same way as the spraying space 105a, which can ensure that the cooling tower 10 has no fogging problem in summer and can improve the heat exchange efficiency as much as possible.

[0126]

Cooling tower 20

[0127] The difference between the cooling tower 20 of this embodiment and the above-mentioned cooling tower 10 is that for each spraying space 105a, a cover plate 109 along the stacking direction of the packing module 1 is further disposed substantially horizontally above the partition plate 105. By providing the cover plate 109, the partition plate 105 and the packing module 1, a plurality of spaced spaces 205a, 205b are defined. In this embodiment, the cover plate 109 is only provided in the spraying space 205a for spraying hot water, and the cover plate 109 is not provided in the air extraction space 205b for exhausting air. Of course, the cover plate 109 can also be provided for both the spraying space 105a and the air extraction space 205b, and the cover plate 109 can be a continuous plate or formed by combining a plurality of plates, and the cover plate 109 can be flipped or opened in a split manner along the partition walls 105 on one or both sides to form a detachable or openable manner, so that the spraying space 205a and the air extraction space 205b can be switched.

[0128] Operating state 1: This operating state is particularly suitable for winter in the northern part of China. In this state, the working process of the cooling tower 20 is similar to that of the above-mentioned cooling tower 10. However, since the cover plate 109 is provided above the spraying space 205a, the spraying space 205a will not play the role of air extraction in principle. Only hot water passes downward through the flow paths R1 or R2 of the packing module corresponding to the spraying space 205a. Therefore, in the exhaust layer 106 of the cooling tower 20, there is only dry hot air from the air extraction space 205b.

[0129] Therefore, only dry hot air in the cooling tower 20 is sucked by the fan 107 and discharged from the air outlet 108, so that the moisture in the hot air discharged from the cooling tower 20 is reduced as much as possible, thereby further improving the anti-fogging ability of the cooling tower 20 in winter. And since the discharged air is only dry hot air, the amount of water discharged from the cooling tower 20 is also less, which is more conducive to water conservation.

[0130] In the case where the cover plates 109 that can be opened and closed (hinged or split or removable) are provided for both the spraying space 205a and the air extraction space 205b, by opening the cover plate above the spraying space 205a and closing the cover plate above the air extraction space 205b, and adjusting the spraying part 104, the functions of the spraying space 205a and the air extraction space 205b can be swapped in the same way as the above-mentioned cooling tower 10, and the flow paths R1 or R2 of the packing module 1 corresponding to the original air extraction space 205b can be cleaned, thus avoiding the shutdown of the cooling tower 20.

[0131] Of course, by only opening the cover plate 109, the same operating state as that of the above-mentioned cooling tower 10 can be achieved, and its working efficiency and working results are also roughly the same.

[0132] Operating state two: In the summer operating state, by removing or opening the cover plate 109 above the spray space 205a, adjusting the spray part 104 to spray hot water on the space 205b and the spray space 205a in the same way, the cooling tower 20 can achieve the same operating state of improving the heat exchange efficiency in summer as the above-mentioned cooling tower 10.

[0133] In the cooling tower 20 of the present embodiment, the cover plate 109 provided above the spaced-apart spaces 205a and 205b is a flat plate, but it is not limited thereto. It can also be a plate extending from the partition plates 105 on both sides of the packing module 1 in the stacking direction of the spaced-apart spaces 205a and 205b to the middle, and overlapping to enclose the spaced-apart spaces 205a and 205b, forming an upward or downward apex angle at the overlapping part. That is, as long as the upper part of the spaced-apart spaces 205a and 205b can be enclosed, there is no limitation on the composition method of the cover plate 109.

[0134] In the above embodiment, the flow rectifying piece 230 is disposed in the upper left guiding portion 201 formed between the packing sheets B-A in the stacking direction of the upper drainage portion 200 of the first flow path R1.

[0135] Furthermore, the flow rectifying piece 240 is disposed in the upper right guiding portion 202 formed between the packing sheets A-B in the stacking direction of the upper drainage portion 200 of the second flow path R2.

[0136] On the other hand, the flow rectifying piece 330 is disposed in the lower left guiding portion 301 formed between the packing sheets B-A in the stacking direction of the lower drainage portion 300 of the first flow path R1.

[0137] Furthermore, the flow rectifying piece 340 is disposed in the upper right guiding portion 202 formed between the packing sheets A-B in the stacking direction of the lower drainage portion 300 of the second flow path R2.

[0138] Since the first upper end opening 210 and the second upper end opening 220 each account for approximately half of the width of the packing module 1, in fact, the flow rectifying piece 230 is embedded in a region that is approximately a right trapezoid formed by starting from approximately the middle of the upper edge of the packing piece B - A, extending downward to the left edge of the upper guiding portion 200, then along the lower end line of the side upper guiding portion 200 to the right edge of the upper guiding portion 200, and then turning obliquely upward to point to approximately the middle of the upper edge of the packing piece A (B). For the packing piece A, it is offset backward at this right trapezoid region, and conversely for the packing piece B, it is offset forward. Thus, in the stacking direction, the front packing piece A and the rear packing piece B, that is, between the packing pieces A - B, a tight fit is formed at the periphery of the first upper end opening 210. Therefore, the open width in the stacking direction between the front packing piece B and the rear packing piece A, the packing pieces B - A at the first upper end opening 210 is 2d. That is to say, in this right trapezoid region, the distance in the stacking direction at the upper first upper end opening 210 is approximately 2d, while the distance in the stacking direction at the lower part connected to the heat exchange portion 400 is the interval d between the packing pieces A and B, thereby forming the space of the upper left guiding portion 201.

[0139] The cross - section of the flow rectifying piece 230 in the horizontal direction is in a folded shape extending perpendicular to the stacking direction. The folding amplitude is large and the folding span is small near the first upper end opening 210 in the upper part. During the process of extending downward towards the heat exchange portion 400, the folding amplitude gradually decreases and the folding span gradually increases to fill the space of the upper left guiding portion 201. By forming the folding of the flow rectifying piece 230 in the horizontal direction, multiple guiding flow paths are formed from the first upper end opening 210 to the heat exchange portion 400. Each guiding flow path has a large thickness in the stacking direction at the upper end and a small width in the horizontal direction, while at the lower end, it has a small thickness and a large width. Thus, it can effectively guide the hot water flowing in from the first upper end opening 210 with approximately half the width of the packing module 1 evenly to the heat exchange portion 400 with approximately the full width of the packing module 1. And whether it is a single guiding flow path or the overall guiding flow path, the change in the cross - sectional area of the guiding flow path from top to bottom is as small as possible to reduce the fluid resistance. Good passing efficiency can be obtained for both the hot water sprayed from above and the air sucked from bottom to top.

[0140] The flow rectifying piece 240 located in the space of the upper right guiding portion 202 has the same structure, except that the set position is rotationally symmetric with the flow rectifying piece 240 in the horizontal direction.

[0141] For the current rectifying sheets 330 and 340, similar to the upper left section guiding part 201 and the upper right section guiding part 202 of the upper section guiding part 200, they are respectively arranged in the lower left section guiding part 301 formed by offsetting the inverted right trapezoidal area of the filler sheet B - A in the lower section guiding part 300 outward in the stacking direction, and in the lower right section guiding part 302 formed by offsetting the inverted right trapezoidal area of the filler sheet A - B in the lower section guiding part 300 outward in the stacking direction. Multiple flow paths are formed by the rectifying sheets 330 and 340 in the lower left section guiding part 301 and the lower right section guiding part 302 respectively, with the upper ends having a small thickness in the stacking direction and a large width in the horizontal direction, and the lower ends having a large thickness and a small width, so as to guide the water in the heat exchange part 400 with a substantially full width of the first and second flow paths R1 and R2 from the filler module 1 to the first and second lower openings 310 and 320 with a substantially half width.

[0142] That is, for the rectifying sheets 330 and 340, they are inverted, with a large bending amplitude and a small bending span at the first and second lower openings 310 and 320. During the process of extending upward towards the heat exchange part 400, the bending amplitude gradually decreases and the bending span gradually increases.

[0143] The rectifying sheet 330 located in the space of the lower left section guiding part 301 and the rectifying sheet 340 located in the space of the lower right section guiding part 302 are rotationally symmetric in the horizontal direction in the same way.

[0144] Therefore, when the first and second upper openings 210 and 220 and the first and second lower openings 310 and 320 are all approximately half the width of the filler module 1, if the vertical lengths of the upper and lower section guiding parts 200 and 300 are the same, the upper left section guiding part 201, the upper right section guiding part 202, the lower left section guiding part 301, and the lower right section guiding part 302 can form a rotationally symmetric structure. Thus, the rectifying sheets 230, 240, 330, and 340 can be the same components, enabling the filler module 1 to only require 3 types of components during production, namely the filler sheet A, the filler sheet B, and a common rectifying sheet. This not only significantly reduces the mold cost and the production cost of components for manufacturing the filler module 1, but also when assembling the filler sheet A, the filler sheet B, and the rectifying sheet, there is no need to consider the model differences of each rectifying sheet, making the assembly convenient and thus greatly reducing the overall production cost of the filler module 1.

[0145] According to the above preferred embodiment, by offsetting and fitting the packing sheets A and B at the upper guiding portion and the lower guiding portion respectively, the first upper end opening, the second upper end opening, the first lower end opening, and the second lower end opening are stacked in the stacking direction. Without considering the thickness of the packing sheets A and B, the total opening size in the stacking direction is substantially the same as the stacking thickness of the packing module in the stacking direction.

[0146]

Fifth Embodiment

[0147] The difference from the above embodiments lies in the setting positions of the upper end openings of the first flow path 1000G and the second flow path 1000W. In this embodiment, in the left-right direction at the upper end of the packing module 1000, the upper end opening G of the first flow path 1000G, which is the first upper end opening, is set in the middle; the upper end opening W of the second flow path 1000W, which is the second upper end opening, includes an upper end opening W1 provided on the left side of the upper end opening G and an upper end opening W2 provided on the right side of the upper end opening G. That is, in this embodiment, the second flow path 1000W has two upper end openings W and is set in a manner that sandwiches the upper end opening G of the first flow path 1000G.

[0148] In this 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 through the upper guiding portion of the first flow path 1000G, and the upper end opening G, which occupies the middle portion in the width direction at the upper end of the packing module 1000, is guided to the first heat exchange portion 401 that occupies the substantially entire width of the packing module 1000.

[0149] 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 through the upper guiding portion of the second flow path 1000W, and the upper end openings W1 and W2, which occupy both sides of the upper end opening G of the first flow path 1000G in the width direction at the upper end of the packing module 1000, are guided to the second heat exchange portion 402 that occupies the substantially entire width of the packing module 1000.

[0150] Specifically, in the front - rear direction of the stacked filler sheets, a first flow path 1000G is formed between the filler sheet 1000B and the filler sheet A; a second flow path 1000W is formed between the filler sheet 1000A and the filler sheet 1000G. Between the heat - exchange part 401 of the first flow path 1000G and the heat - exchange part 402 of the second flow path 1000W, the distance between the filler sheet 1000A and the filler sheet 1000B is substantially uniform, that is, the filler sheet 1000A and the filler sheet 1000B are arranged substantially parallel to each other at the parts of the first heat - exchange part 401 and the second heat - exchange part 402.

[0151] Furthermore, for the filler sheets A and B, above the heat - exchange part 400 formed by the first and second heat - exchange parts 401 and 402 arranged in a stacked manner, an upper - section guiding part 200 of the first and second flow paths 1000G and 1000W is provided.

[0152] In the present embodiment, by making the filler sheet 1000B and the filler sheet 1000A offset in opposite directions from the upper - end opening G to the region of the part of the first heat - exchange part 401 at the upper - section guiding part 200, first offset parts 1100B and 1100A are formed, increasing the distance between them, thereby forming a first upper - end opening part 1100 of the first upper - section guiding part 200G. Furthermore, at the upper - section guiding part 200 of the filler sheets 1000A and 1000B, due to the formation of the first offset parts 1100A and 1100B, the filler sheets 1000A and 1000B are brought closer together at this part.

[0153] On the other hand, by making the filler sheet 1000A and the filler sheet 1000B offset in opposite directions from the upper - end openings W1 and W2 on both sides of the upper - end opening G to the region of the part of the second heat - exchange part 402 at the upper - section guiding part 200, second offset parts 1200A and 1200B are formed, increasing the distance between them, thereby forming a second upper - end opening part 1200 of the second upper - section guiding part 200W. Furthermore, at the upper - section guiding part 200 of the filler sheets 1000B and 1000A, due to the formation of the second offset parts 1200B and 1200A, the filler sheets 1000B and 1000A are brought closer together at this part.

[0154] In the present embodiment, as described above, by forming offset portions in the upper sections of the packing sheets 1000A and 1000B, a first upper end opening 1100 and a second upper end opening 1200 are formed in the upper section of the packing module 1000. Furthermore, a first upper end opening G and second upper end openings W1 and W2 are formed at the upper end edges of the first upper end opening 1100 and the second upper end opening 1200. Furthermore, in the first flow path 1000G, the first upper end opening G, which occupies a partial width in the middle of the width direction of the packing module 1000, communicates with the first heat exchange section 401 that occupies substantially the entire width of the packing module 1000; and in the second flow path 1000W, the second upper end openings W1 and W2, which occupy partial widths on both sides in the width direction of the packing module 1000, communicate with the second heat exchange section 402 that occupies substantially the entire width of the packing module 1000. From this, it can be known that in one unit of the second flow path 1000W formed by the packing sheets 1000A - 1000B, the second upper end openings W1 and W2 of the second flow path 1000W communicate with the common second heat exchange section 402.

[0155] Furthermore, the thickness dimensions of the first and second upper end openings G, W1, and W2 in the stacking direction of the packing module 1000 are greater than the distances in the stacking direction of the respective packing sheets 1000A and 1000B at the heat exchange section 400.

[0156] In the present embodiment, in order to make the fluids in the first flow path 1000G and the second flow path 1000W uniform, flow rectifying sheets are also provided in the respective first and second upper section guiding portions 200G and 200W.

[0157] As the first flow rectifying sheet 1300G in the first flow path 1000G, it is provided in the first upper section guiding portion 200G between the first upper end opening G and the first heat exchange section 401. The first upper section guiding portion 200G serves to connect the first upper end opening G to the first heat exchange section 401 with substantially the entire width. Therefore, the first flow rectifying sheet 1300G provided in the first upper section guiding portion 200G is formed in a substantially isosceles trapezoid shape and has a plurality of flow guiding grooves with a gradually increasing width from top to bottom.

[0158] Furthermore, as the second flow rectifying sheet 1300W in the second flow path 1000W, it is provided in the second upper section guiding portion 200W between the second upper end openings W1 and W2 and the second heat exchange section 402. The second upper section guiding portion 200W serves to connect the second upper end openings W1 and W2 to the second heat exchange section 402 with substantially the entire width. Therefore, the second flow rectifying sheet 1300W provided in the second upper section guiding portion 200W is formed in a shape of substantially two right trapezoids and has a plurality of flow guiding grooves with a gradually increasing width from top to bottom.

[0159] In the present embodiment, as described above, since the front projections of the packing sheets 1000A and 1000B are substantially rectangular, the first upper end opening 1100 of the first upper guiding portion 200G formed by the first biasing portions 1100B and 1100A is formed into an inverted substantially triangular shape; and the second upper end opening 1200 of the second upper guiding portion 200W formed by the second biasing portions 1200A and 1200B is formed into an inverted substantially right-angled triangular shape located at the left and right corner portions at the upper ends of the packing sheets 1000A and 1000B. At this time, the first upper end opening G and the second upper end openings W1 and W2 are located at the upper edge of the packing module 1000.

[0160] Thus, at positions corresponding to the first upper end opening 1100 and the second upper end opening 1200 of the first and second upper guiding portions 200G and 200W on the first rectifying sheet 1300G and the second rectifying sheet 1300W, longitudinal rectifying portions in the shape of an inverted substantially triangular shape and an inverted substantially right-angled triangular shape are also formed. The function of this longitudinal rectifying portion is to preliminarily partition the first and second upper guiding portions 200G and 200W of the first and second flow paths 1000G and 1000W to ensure that the fluid throughput in each flow guiding groove is substantially uniform within the diagonal rectifying portion below it.

[0161] Furthermore, in the present embodiment, in addition to forming the first upper end opening 1100 and the second upper end opening 1200 by providing biasing portions in the first and second upper guiding portions 200G and 200W respectively, and providing the first and second rectifying sheets 1300G and 1300W, the first and second lower guiding portions 400G and 400W can be formed by providing the same biasing portions, and the third and fourth rectifying sheets 1300G' and 1300W' are provided. Furthermore, the same first and second lower end openings are formed.

[0162] Based on the packing module of the present embodiment, when constructing a cooling tower, multiple packing modules can be arranged side by side in a substantially horizontal direction. The differences from the first to fourth embodiments will be described in detail below.

[0163] (Usage Example 1) In the present embodiment, since the first upper end opening G of the first flow path 1000G is located in 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 on both sides of the width direction of the packing module 1000, therefore, when the packing modules 1000 are arranged side by side, as Figure 27 shown, a schematic diagram of Usage Example 1 of the packing module 1000 of the present embodiment is shown.

[0164] Different from the first to fourth embodiments, in this usage example, the lower end of the partition plate 2005 that separates the air flow path and the spray water flow path and is arranged above the packing module 1000, and the sealing part between the lower end and the packing module 1000 are all located inside the dimension in the width direction of the packing module, and the situation where the lower end of the partition plate 105 is located at the joint part between the packing modules as described above will not occur. In this way, the sealing between the packing module 1000 and the partition plate 2005 becomes easier, and the spray flow path and the air flow path are separated more thoroughly as much as possible. As a result, the cold air flowing in from below the packing module 1000, after passing through the packing module 1000 and exchanging heat with the hot water in the adjacent flow path and being discharged above the packing module 1000, its absolute humidity never changes.

[0165] However, the air after heat exchange discharged above the packing module 1000 exchanges heat with the hot water in the adjacent flow path and becomes dry and hot air. While maintaining the absolute humidity, the air temperature rises, and the relative humidity drops significantly.

[0166] In this usage example, since a partition plate 2005' is also arranged below the packing module 1000, in the cooling tower 2000, the spray hot water after passing through the packing module 1000 supplies as little moisture as possible to the cold air inhaled below the packing module 1000. In the packing module 1000, the cold air and the hot water in the adjacent flow path are isolated from each other and do not supply moisture to the air flow path. Furthermore, when the inhaled cold air is discharged above the packing module 1000, due to the separation of the partition plate 2005, it is further avoided to obtain moisture from the spray part.

[0167] Therefore, in this usage example, by isolating the air flow path and the spray water in the cooling tower 2000 as much as possible, it is possible to supply as little moisture as possible to the inhaled air. On the other hand, in the spray water flow path, since a valve plate 2009 in a closed state is arranged above the nozzle, the hot air of the spray hot water is mixed into the discharged air as little as possible, and the inhaled cold air below the packing module 1000 is also separated by the partition plate 2005'. Therefore, the spray hot water forms a closed flow path and supplies as little moisture as possible to the inhaled air and the discharged air of the cooling tower 2000. Thus, even in winter in the northern part of our country, the fog discharged by the cooling tower 2000 can be greatly reduced.

[0168] (Usage Example 2) In addition, the valve plate 2009 can also be set to a failure state (opened or not set) to become the state as shown in Figure 28 Even so, for the cold air inhaled below the packing module 1000, after the cold air is discharged above the packing module, only a small amount of water vapor above the partition plate 2005 is mixed with the cold air after heat exchange.

[0169] Since the temperature of the cold air after heat exchange increases while the absolute humidity remains unchanged, the saturation is low. On the other hand, the amount of water from the spray flow path itself is limited. Therefore, the air after heat exchange with a significantly decreased saturation can be effectively utilized to absorb the water released from the spray section. Except for the case where the winter temperature is extremely low, the cooling tower 2100 of this usage example 2 can also effectively achieve the demisting effect.

[0170] In the above 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 part between adjacent packing modules 1000 is limited to the range of the hot water spray flow path. In this case, for the first flow path 1000G as the air flow path, while ensuring the airtightness between the lower end of the partition plate 2005 and the packing module 1000, as much as possible, all the air inhaled by the cooling tower 2000 can flow through the first flow path 1000G.

[0171] For the installation of the packing modules, there will inevitably be a certain gap between the packing modules. Otherwise, the installation of the packing modules will become a problem. According to the packing module 1000 of this embodiment, by setting the first upper end opening G in the middle of the width direction of the packing module 1000 and setting the second upper end opening W on both sides of the width direction of the packing module 1000, the adjacent upper end openings between adjacent packing modules 1000 can all be the second upper end opening W, so that the second upper end opening W can be set as the inflow port of the hot water spray. Thus, the problem of air leakage through the installation gap between the packing modules 1000 can be effectively reduced. As in the first to fourth embodiments, there will inevitably be a gap between the packing modules 100 through which part of the air flows directly without passing through the packing modules, which may lead to a problem of reduced heat exchange efficiency. Furthermore, in the case where the gap between the packing modules 100 is too large due to construction errors, mistakes, etc., the air flow rate through the gap between the packing modules 100 will increase significantly, making it even more impossible to ensure the uniformity of the air resistance of the entire cooling tower, and thus inevitably affecting the stacking direction of the packing modules in the entire cooling tower and the uniformity of the heat exchange efficiency between the packing modules.

[0172] Using the packing module 1000 of this embodiment can properly solve the above problems.

[0173] (Usage Example 3) As Usage Example 3 of the packing module 1000 of this embodiment, in addition to having the advantages of the above Usage Examples 1 and 2, it can further improve the heat exchange efficiency of the cooling tower, significantly reduce the cost of the packing module, and further enhance the convenience of installation and maintenance. The following is a detailed description.

[0174] In this usage example, as Figure 29 shown, the cooling tower 3000 is constructed using the packing module 1000. Below, only the differences between the cooling tower 3000 and the foregoing embodiments will be described.

[0175] In the cooling tower 3000, different from the foregoing, a specified installation interval 3999 of 300 - 600 mm is provided between each packing module 1000, and a closing plate 3998 is preferably provided on the 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 into a plane corresponding to the interval of the packing module 1000.

[0176] At this time, contrary to the foregoing usage examples 1 and 2, it is preferable to use the second flow path 1000W of the packing module 1000 as the air flow path and the first flow path 1000G as the flow path of the sprayed water.

[0177] In this way, when designing the cooling tower 3000, the packing modules 1000 can be intentionally spaced apart, and this installation interval 3999 allows workers to enter during the installation and maintenance of the packing modules 1000, so as to move and inspect the state between the packing modules 1000.

[0178] In particular, when installing the packing module 1000, since the distance of the packing module 1000 is relatively long in the stacking direction of the packing module 1000, the packing module 1000 is usually only stacked to a specified thickness after being divided, and a unit of the packing module 1000 is formed. By arranging each unit in a straight line and approaching each other in the stacking direction of the packing module 1000, a whole row of packing modules 1000 is formed. Therefore, during the installation construction of the cooling tower 3000, in order to ensure that the cooling tower 3000 has as little air leakage and water leakage as possible, it is necessary to ensure that each unit of the packing module 1000 is in a straight line during installation. When there is no installation interval 3999 between the packing modules 1000 in the horizontal direction, it is almost impossible to adjust the straightness of the units of each packing module 1000 in the longitudinal direction, and it is necessary to precisely control the installation accuracy when installing each unit, so the installation efficiency needs to be improved.

[0179] In response to this, according to this usage example, since the installation interval 3999 is provided between the packing modules 1000 in the horizontal direction, when installing the modules of each packing module 1000 along the stacking direction, the operator can easily adjust each unit of the packing module 1000 by means of this installation interval 3999. Even in the case of damage to a certain unit due to some special accident, after demolishing the damaged unit, the units before and after it can be easily moved and replaced, and a new unit can be supplemented from the end of the stacking direction of the packing module 1000 to complete the repair.

[0180] When the closing plate 3998 is provided in the installation interval 3999, it is preferred that the closing plate 3998 can be removed or erected, so that the closing plate 3998 is ineffective. At this time, because the second flow path 1000W is provided as an air flow path, a large amount of air only passes through the installation interval 3999. At this time, the cooling efficiency for hot water is greatly reduced, which can meet some special needs in factory production.

[0181] (Use example 4) Figure 30 1 is a schematic diagram of use example 4. In this use example, similar to use example 3, a space is provided between the filler modules 1000 in the lateral direction, but a normal filler module F is further provided to fill the space.

[0182] The common packing module F may be any existing packing module. For example, the most widely used packing module F is a packing module F formed by stacking a plurality of packing sheets, in which no separated flow path exists in the packing module F. Hot water is poured into the sheet-shaped heat exchange space formed by two adjacent packing sheets in the stacking direction from the upper end opening, and the fan of the cooling tower 4000 is used to draw cold air into the packing module F from the lower end opening, so that the air and the hot water are in direct contact for heat exchange.

[0183] As shown above, in this use case, it is preferred that the second flow path 1000W is a flow path for hot water spraying, and the first flow path 1000G is an air flow path. In this way, in this use case, the second flow path 1000W and the packing module F are simultaneously supplied with hot water, and the hot water flowing into the packing module 1000 through the second upper end openings W1 and W2 of the packing module 1000 performs heat exchange in the packing module 1000 with the air sucked in from the second lower end opening G' of the packing module 1000, and on the other hand, the hot water sprayed into the packing module F directly contacts the air sucked in from its lower end in the packing module F, and performs heat exchange in the packing module 1000.

[0184] 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 flowing out from the upper end of the filler module F becomes saturated hot air.

[0185] On the other hand, due to the setting of the second upper end openings W1 and W2, the air resistance in the second flow path 1000W is very large, so the amount of air actually discharged upward from the second upper end opening W of the filling module 1000 is very small, which is very small compared to the amount of air passing through the filling module F.

[0186] Therefore, the low-saturation hot air mainly discharged from the first upper-end opening G of the packing module 1000, the saturated hot air discharged from the packing module F, and a very small amount of saturated hot air discharged from the second upper-end opening W1 / W2 of the packing module 1000 are mixed above the packing module. Thereby, the unsaturated hot air is effectively utilized, the saturation of the mixed air is reduced, and on the premise of ensuring sufficient fog elimination effect, the heat exchange efficiency of the cooling tower is greatly improved.

[0187] According to the packing module 1000 of the present embodiment, by providing a first upper-end opening G in the middle of the top width direction and providing second upper-end openings W (W1, W2) on both sides of the first upper-end opening G respectively, when using the packing module 1000 to build cooling towers 2000, 2100, 3000, 4000, etc., it can be more flexible, and the air passage and the hot water passage can also be set flexibly. Especially when using the first flow path 1000G connected by the first upper-end opening G as the air flow path, the isolation between the air flow path and the hot water spray flow path is more thorough. Thereby, the relative humidity of the air after heat exchange can be reduced as much as possible to improve the fog elimination effect, which is especially suitable for the situation in northern China in winter.

[0188] However, the packing module 1000 provided in the present embodiment and the cooling tower having the packing module 1000 are not limited to the situations described in the present embodiment.

[0189] In the present embodiment, by making the packing module 1000 include upper-section guiding parts 200G, 200W in the upper section and the heat exchange parts 401, 402 below it, the first flow path 1000G and the second flow path 1000W formed by alternately overlapping packing sheets 1000A and packing sheets 1000B are formed into an alternately stacked structure. The first flow path 1000G includes a first heat exchange part 401, the second flow path 1000W includes a second heat exchange part 402, and the first heat exchange part 401 and the second heat exchange part 402 overlap to form the heat exchange part 400.

[0190] Among them, in the middle of the upper-section guiding part, the packing sheet 1000A has an offset part 1100A offset forward in the stacking direction, and on both sides of the upper-section guiding part, it has an offset part 1100B offset backward in the stacking direction. In the middle of the upper-section guiding part, the packing sheet 1000B has an offset part 1200A offset backward in the stacking direction, and on both sides of the upper-section guiding part, it has an offset part 1200B offset forward in the stacking direction.

[0191] Thus, by laminating the packing sheets 1000A and 1000B, the first upper end opening G is formed by the offset portions 1100A and 1100B formed in the middle of the upper section guiding portion of the packing sheets 1000A and 1000B. The second upper end opening W is formed by the offset portions 1200A and 1200B formed on both sides of the upper section guiding portion of the packing sheets 1000B and 1000A.

[0192] In the first flow path 1000G, the first upper end opening G communicates with the first heat exchange portion 401 having a substantially full width dimension of the packing module 1000. In the second flow path 1000W, the second upper end opening W communicates with the second heat exchange portion 402 having a substantially full width dimension of the packing module.

[0193] In the present embodiment, a lower section guiding portion is further provided below the heat exchange portion. For the first and second flow paths 1000G and 1000W, the structure of the lower section guiding portion is inverted with respect to the first and second upper section guiding portions 200G and 200W, that is, it includes corresponding offset portions, and forms the first and second lower end openings, and further includes inclined flow guiding portions that are embedded in the guiding portions including the offset portions and obliquely connect the first and second lower end opening portions with the first and second heat exchange portions 401 and 402, thereby forming the flow rectifying sheets 1300G' and 1300W'. At this time, the same parts as the flow rectifying sheets 1300G and 1300W can be used as the flow rectifying sheets 1300G' and 1300W', and they can be inverted.

[0194] The flow rectifying sheets 1300G and 1300W are located in the upper section guiding portion of the packing module 1000. Especially when guiding hot water to flow in, it is necessary to introduce the sprayed hot water from the first upper end opening G or the second upper end opening W (W1, W2) in the middle of the width direction into the first heat exchange portion 401 or the second heat exchange portion 402 with a substantially full width. Therefore, the lower end of the flow rectifying sheet is bent to form a flow guiding groove and gradually flattened, so that the guided fluid is evenly distributed on the surface of the heat exchange portion of the packing sheets 1000A and 1000B. However, for the flow rectifying sheets 1300G'' and 1300W'', since they are in the lower section guiding portion, when guiding the sprayed water out of the packing module 1000, the uniformity does not need to be considered. Therefore, the flattened portion can be removed, and only the flow guiding path portion formed by bending is retained. This can also avoid the situation that low-velocity fluid, especially the sprayed hot water, causes the flow path to narrow due to the flattened portion at the upper end of the flow rectifying sheets 1300G' and 1300W' when flowing out of the packing module 1000, resulting in the accumulation of debris in the water and blockage after long-term use.

[0195] The above has described in detail the packing module of the preferred embodiment of the present invention and the cooling tower having the packing module. However, 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 this application.
