A filler unit is disposed inside the cooling tower. The filler is composed of sheet members stacked at intervals. The filler unit is composed of multiple fillers housed in a casing. Air flows horizontally inside the filler unit, and water flows vertically downward inside the filler unit. Inside the filler unit, air and water come into contact with each other, and the air is cooled by utilizing the latent heat generated by the evaporation of water. Examples of such cooling towers include those described in the following patent documents.

Japanese Patent Application Publication No. 4-217795

The filler is made of PVC (polyvinyl chloride) for the purpose of reducing weight, which makes it soft and gives it a low natural frequency compared to the casing, which is made of steel structure. Therefore, if an earthquake causes the cooling tower to vibrate, the filler will vibrate significantly relative to the casing, and there is a risk that the filler will be damaged. Therefore, it is possible to prevent damage by, for example, fixing each filler to the casing. However, there is an issue that the filler is made up of a large number of stacked sheets, making it difficult to manufacture and maintain.

The present disclosure aims to solve the above-mentioned problems and provide a cooling tower and filler unit that improves earthquake resistance and facilitates maintenance such as installing and replacing filler.

The cooling tower of the present disclosure, which is intended to achieve the above object, comprises a housing in which an air flow path is provided along a horizontal direction and a cooling water flow path is provided along a vertical direction, and a filler unit disposed inside the housing at a position where the air flow path and the cooling water flow path intersect, the filler unit comprising a casing having a pair of support plates, a partition plate disposed inside the casing between the pair of support plates and spaced apart from the casing in the horizontal direction intersecting the air flow path, and a filler material disposed between the pair of support plates and the partition plate.

The filler unit of the present disclosure also includes a casing having a pair of support plates, a partition plate disposed inside the casing at a distance between the pair of support plates, and a filler material disposed between the pair of support plates and the partition plate.

The cooling tower and filler unit disclosed herein can improve earthquake resistance and facilitate maintenance such as installing and replacing the filler.

[First embodiment]
<Cooling tower>
FIG. 1 is a schematic configuration diagram showing a cooling tower according to a first embodiment.

As shown in FIG. 1, the cooling tower 10 brings air into contact with cooling water (water) and uses the latent heat generated by the evaporation of the cooling water to exchange heat between the air and the cooling water, thereby cooling the air. The cooling tower 10 includes a housing 11, a filler unit 12, a blower 13, and a circulation pump 14.

The housing 11 has an upper frame 21, a lower frame 22, and louvers 23. The upper frame 21 and the lower frame 22 are arranged along the horizontal direction and are arranged facing each other in the vertical direction. The louvers 23 are arranged along the vertical direction on both sides of the upper frame 21 and the lower frame 22 in the horizontal direction. The louvers 23 are arranged between the upper frame 21 and the lower frame 22, and form the side walls of the housing 11.

The upper frame 21 is arranged in the horizontal direction, and an upper water tank 24 is provided on each end side in the horizontal direction. A watering nozzle 25 is attached to the lower part of the upper water tank 24. The lower frame 22 is arranged in the horizontal direction, and a lower water tank 26 is provided in the center. The louvers 23 are arranged between each end of the upper frame 21 in the horizontal direction and each end of the lower frame 22 in the horizontal direction. The louvers 23 are arranged in the vertical direction, and multiple openings connect the outside and inside of the housing 11.

The filler units 12 are arranged on both sides inside the housing 11. The filler units 12 are arranged inside the housing 11 from the louvers 23, between each horizontal end side of the upper frame 21 and each horizontal end side of the lower frame 22. The upper part of the filler unit 12 faces the watering nozzle 25 of the upper water tank 24 in the upper frame 21 with a gap. The lower part of the filler unit 12 faces each horizontal end side of the lower frame 22 with a gap.

The housing 11 and the filler unit 12 are approximately symmetrical with respect to the center line O that runs vertically through the cooling tower 10.

The blower 13 is disposed at the top of the housing 11, i.e., at the top center of the upper frame 21. The blower 13 has a rotating shaft 27 and a fan 28. The rotating shaft 27 is disposed along the center line O that is along the vertical direction of the cooling tower 10. The fan 28 is fixed to the outer periphery of the rotating shaft 27. The rotating shaft 27 can be driven to rotate by a drive device (not shown). The blower 13 can suck air inside the housing 11 upward and expel it to the outside by rotating the fan 28 by the rotating shaft 27.

The circulation pump 14 circulates the cooling water inside the housing 11. The circulation pump 14 is connected to a cooling water supply line L11 that passes through the inside of the housing 11 and supplies cooling water to the upper water tank 24. The circulation pump 14 is also connected to a cooling water return line L12 that returns the cooling water stored in the lower water tank 26 and sends it to the cooling water supply line L11.

In the cooling tower 10, air outside the housing 11 is taken into the housing 11 through the louvers 23, and an air flow path A1 is formed that passes horizontally through the filler unit 12. In addition, in the cooling tower 10, air that has passed horizontally through the filler unit 12 flows vertically upward through the center of the housing 11, and an air exhaust path A2 is formed that exhausts the air to the outside of the housing 11 through the blower 13. In addition, in the cooling tower 10, a cooling water flow path W1 is formed in which cooling water sprayed from the spray nozzles 25 of the upper water tank 24 in the upper frame 21 passes vertically through the filler unit 12 and reaches the lower water tank 26 of the lower frame 22. In the cooling tower 10, the filler unit 12 is disposed at the position where the air flow path A1 and the cooling water flow path W1 intersect.

Therefore, when the blower 13 is driven, the rotating fan 28 creates a suction force that draws the air inside the housing 11 upward and discharges it to the outside of the housing 11. Then, air outside the housing 11 is taken into the housing 11 through the louvers 23. The air taken into the housing 11 passes horizontally through the filler unit 12, then flows upward inside the housing 11 and is discharged to the outside of the housing 11 through the blower 13. On the other hand, when the circulation pump 14 is operated, the cooling water stored in the lower water tank 26 is returned by the cooling water return line L12 and sent to the cooling water supply line L11. The cooling water sent to the cooling water supply line L11 is supplied to the upper water tank 24. The cooling water in the upper water tank 24 is sprayed downward by the spray nozzle 25, and the cooling water passes vertically downward through the filler unit 12. The cooling water passes through the filler unit 12, is received by the lower frame 22, and is stored in the lower water tank 26.

At this time, the air flowing through the air flow path A1 and the cooling water flowing through the cooling water flow path W1 exchange heat with each other through the filler unit 12 arranged at the position where the air flow path A1 and the cooling water flow path W1 intersect. In other words, the air and the cooling water come into contact with each other through the filler unit 12, and the air is cooled by utilizing the latent heat generated by the evaporation of the cooling water.

<Configuration of the filling material unit>
Fig. 2 is a front view showing the filler unit of the first embodiment, Fig. 3 is a plan view showing the filler unit, and Fig. 4 is a perspective view showing the filler unit. Note that the filler is omitted in Fig. 3.

As shown in Figures 2 to 4, the filler unit 12 has a casing 31, a partition plate 32, and a filler 33.

The casing 31 has a pair of support plates 41, 42, a plurality of lower support frames 43, a plurality of upper support frames 44, and a pair of reinforcing frames 45, 46. The pair of support plates 41, 42 are arranged vertically and are arranged parallel to each other with a gap in the horizontal direction. The pair of support plates 41, 42 are connected at the lower parts by a plurality of lower support frames 43, and at the upper parts by a plurality of upper support frames 44. The plurality of lower support frames 43 are arranged horizontally, parallel to each other, and arranged at a gap. The plurality of lower support frames 43 have their respective longitudinal ends fixed to the lower parts of the pair of support plates 41, 42. The plurality of upper support frames 44 are arranged horizontally, parallel to each other, and arranged at a gap. The plurality of upper support frames 44 have their respective longitudinal ends fixed to the upper corners of the pair of support plates 41, 42. The reinforcing frame 45 has one longitudinal end fixed to an upper corner of the support plate 41, and the other end fixed to the middle of the lower support frame 43. The reinforcing frame 46 has one longitudinal end fixed to an upper corner of the support plate 42, and the other end fixed to the middle of the lower support frame 43.

The partition plate 32 is disposed inside the casing 31 at a distance from the casing 31 in the horizontal direction intersecting the air flow path A1. That is, the partition plate 32 is disposed between a pair of support plates 41, 42 constituting the casing 31 at a distance from the support plates 41, 42. In this embodiment, a plurality of partition plates 32 (four in this embodiment) are provided, and the plurality of partition plates 32 are disposed at a distance from the support plates 41, 42 and at a distance from each other. The plurality of partition plates 32 have the same configuration, and the lower portions are fixed to the lower support frame 43 and the upper portions are fixed to the upper support frame 44. The plurality of partition plates 32 may be fixed to the reinforcing frames 45, 46.

The filler 33 is, for example, a sheet material having a plurality of protrusions on its surface, laminated in the thickness direction. The plurality of sheet materials are arranged vertically and laminated horizontally. The filler 33 (sheet material) is, for example, made of PVC (polyvinyl chloride). The filler 33 is arranged between the casing 31 and the partition plate 32. That is, the filler 33 is arranged between the pair of support plates 41, 42 constituting the casing 31 and the partition plate 32. In this embodiment, a plurality of fillers 33 (five in this embodiment) are provided, and the plurality of fillers 33 are arranged between the support plates 41, 42 and the partition plate 32, and are also arranged between the plurality of partition plates 32. Here, the support plates 41, 42 and the partition plate 32 are set to be approximately the same size.

The shapes of the casing 31 and support plates 41 and 42, the shape and number of the partition plates 32, and the shape and number of the filler material 33 are not limited to those described above. For example, a single partition plate 32 may be formed by connecting multiple divided partition plates. Also, it is not necessary to have a casing independent of the housing, and the partition plates may be fixed directly to the frame of the housing, and the filler material may be disposed in the space surrounded by the partition plates and the housing.

<Partition>
FIG. 5 is a perspective view showing the partition plate, and FIG. 6 is a horizontal sectional view showing the partition plate.

5 and 6, the partition plate 32 can have a hollow box shape. The partition plate 32 has a pair of opposing flat surfaces 32a, a pair of opposing side surfaces 32b, and a pair of opposing upper and lower surface portions 32c. The partition plate 32 is a rectangle formed by combining the flat surfaces 32a, the side surfaces 32b, and the upper and lower surface portions 32c, and has a hollow interior. The partition plate 32 has a pair of opposing flat surfaces 32a, so that the filler 33 on both sides of the partition plate 32 can be supported by the surfaces. The partition plate 32 is not limited to such a shape. For example, the partition plate 32 may have a shape in which one of the flat surfaces 32a, the side surfaces 32b, and the upper and lower surface portions 32c is eliminated. Also, the pair of flat surfaces 32a may be only on one side, and may have an opening. That is, the partition plate 32 preferably supports the stacked filler 33 with its surface, but as long as it has enough weight and rigidity to reduce vibration, an opening may be formed to allow communication between the inside and outside. The partition plate 32 is not limited to being hollow, and may be made of a simple plate material or a porous material.

A reinforcing member 51 is disposed inside the partition plate 32. The reinforcing member 51 connects the pair of flat surfaces 32a of the partition plate 32 together, and increases the rigidity of the pair of flat surfaces 32a. Reinforcing members may also be provided to connect the pair of side surfaces 32b together or the pair of upper and lower surface portions 32c together.

Figure 7 is a schematic diagram showing the reinforcing portion of the partition plate, and Figure 8 is a schematic diagram showing a modified example of the reinforcing portion of the partition plate.

The reinforcing member 51 is not limited to the above. For example, as shown in FIG. 7, the reinforcing member 52 may be in a triangular honeycomb shape. Also, as shown in FIG. 8, the reinforcing member 53 may be in a hexagonal honeycomb shape. However, the reinforcing members 51, 52, and 53 are not limited to the above shapes. That is, although it is preferable that the partition plate 32 has a lattice-shaped reinforcing member provided therein, it may be simply a rib.

<Filler unit action>
2 to 4, the filler unit 12 is configured by disposing a plurality of partition plates 32 at intervals between a pair of support plates 41, 42 constituting a casing 31, and disposing the filler 33 between the support plates 41, 42 and the partition plate 32 and between the plurality of partition plates 32. Therefore, the filler unit 12 has high rigidity while suppressing an increase in weight due to the plurality of partition plates 32, and the vibration mass of the filler 33 is dispersed to increase the natural frequency. Then, even if the cooling tower 10 (see FIG. 1) vibrates due to an earthquake, the filler unit 12 and the filler 33 do not vibrate significantly.

[Second embodiment]
9 is a plan view showing a filler unit of a cooling tower according to a second embodiment. Note that the same reference numerals are used to designate members having the same functions as those in the first embodiment, and detailed descriptions thereof will be omitted.

In the second embodiment, as shown in FIG. 9, the filler unit 12A has a casing 31, a partition plate 32, a filler 33, and damping members 61 and 62. Here, the casing 31, the partition plate 32, and the filler 33 are the same as those in the first embodiment, and a description thereof will be omitted.

Damping members 61, 62 are provided between the casing 31 and the partition plate 32, that is, between the support plates 41, 42 constituting the casing 31 and the partition plate 32. The damping member 61 has one end connected to the support plate 41 and the other end connected to the partition plate 32. The damping member 62 has one end connected to the support plate 42 and the other end connected to the partition plate 32. The damping members 61, 62 have the same configuration and damp the displacement of the partition plate 32 relative to the support plates 41, 42 between the support plates 41, 42 of the casing 31 and the partition plate 32.

Figure 10 shows a cross-sectional view of the damping member.

As shown in FIG. 10, the damping member 61 is, for example, a damper device. The cylinder 71 is hollow and a piston 72 is supported inside so as to be freely movable. The inside of the cylinder 71 is divided into chambers 71a and 71b by the piston 72. The piston 72 is formed with a communication hole (orifice) 72a that connects the chambers 71a and 71b. The chambers 71a and 71b are filled with a viscous resistor such as oil. The cylinder 71 is connected to the support plate 41 by a connecting rod 73. The piston 72 is connected to the partition plate 32 by a connecting rod 74.

Furthermore, in the filler unit 12A, restoring members 63, 64 are provided between the casing 31 and the partition plate 32, i.e., restoring members 63, 64 are provided between the support plates 41, 42 constituting the casing 31 and the partition plate 32. The restoring members 63, 64 restore the position of the partition plate 32 relative to the support plates 41, 42 to its original position between the support plates 41, 42 of the casing 31 and the partition plate 32.

The damping member 61 has a restoring member 63 disposed between the support plate 41 and the cylinder 71. The damping member 61 also has a restoring member 64 disposed between the partition plate 32 and the cylinder 71. The restoring members 63 and 64 are, for example, compression coil springs, and are disposed outside the connecting rods 73 and 74. The damping member 62 has a similar configuration.

Therefore, the filler unit 12A is configured such that a plurality of partition plates 32 are arranged at intervals between a pair of support plates 41, 42 constituting the casing 31, and the filler 33 is arranged between the support plates 41, 42 and the partition plate 32 and between the plurality of partition plates 32. In addition, the filler unit 12A has damping members 61, 62 and restoring members 63, 64 arranged between the support plates 41, 42 and the partition plate 32. Then, when the cooling tower 10 (see FIG. 1) vibrates due to an earthquake, the relative displacement between the support plates 41, 42 and the partition plate 32 is damped by the damping members 61, 62. In addition, the restoring members 63, 64 return the partition plate 32 to its original position relative to the support plates 41, 42. In addition, the damping members 61, 62 use viscous resistors, and therefore damp vibrations in proportion to the speed at which the viscous resistors act on the relative displacement between the support plates 41, 42 and the partition plate 32.

[Third embodiment]
11 is a front view showing a filler unit of a cooling tower according to a third embodiment. Note that members having the same functions as those in the first embodiment described above are given the same reference numerals and detailed description thereof will be omitted.

In the third embodiment, as shown in FIG. 11, the filler unit 12B has a casing 31, a partition plate 32, and a filler material 33. Here, the casing 31, the partition plate 32, and the filler material 33 are the same as those in the first embodiment, and the description thereof will be omitted.

The filler unit 12B is provided with a first friction portion 81 that attenuates the displacement of the filler 33 relative to the casing 31 due to friction generated between the casing 31 and the filler 33. That is, the upper surface of the plurality of lower support frames 43 on which the filler 33 is placed, which serves as the first friction portion 81, has a larger surface roughness than the other surfaces. The first friction portion 81 may also be provided on the lower surface of the filler 33.

Furthermore, the filler unit 12B has a frame 82 formed above the casing 31, and the upper filler 83 is disposed inside the frame 92. The filler unit 12B is provided with a second friction portion 84 that attenuates the displacement of the upper filler 83 relative to the casing 31 due to friction generated between the casing 31 and the upper filler 83. That is, the upper surface of the multiple upper support frames 44 on which the upper filler 83 is placed, which serves as the second friction portion 84, is set to have a larger surface roughness than the other surfaces. The second friction portion 84 may be provided on the lower surface of the upper filler 83.

Therefore, when the cooling tower 10 (see FIG. 1) vibrates due to an earthquake, the filler 33 is displaced horizontally relative to the lower support frame 43. At this time, the lower support frame 43 and the filler 33 slide against each other via the first friction portion 81. Then, between the lower support frame 43 and the filler 33, the displacement of the filler 33 relative to the lower support frame 43 is attenuated by the frictional resistance of the first friction portion 81. Also, the upper support frame 44 and the upper filler 83 slide against each other via the second friction portion 84. Then, between the upper support frame 44 and the upper filler 83, the displacement of the upper filler 83 relative to the upper support frame 44 is attenuated by the frictional resistance of the second friction portion 84. As a result, the vibration of the filler unit 12B is reduced.

[Effects of this embodiment]
The cooling tower of the first embodiment comprises a housing 11 in which an air flow path A1 is provided horizontally and a cooling water flow path W1 is provided vertically, and filler units 12, 12A, 12B arranged at a position inside the housing 11 where the air flow path A1 and the cooling water flow path W1 intersect, and the filler units 12, 12A, 12B each have a casing 31 having a pair of support plates 41, 42, a partition plate 32 arranged inside the casing 31 between the pair of support plates 41, 42 and spaced apart from the casing 31 in the horizontal direction intersecting the air flow path A1, and a filler 33 arranged between the pair of support plates 41, 42 and the partition plate 32.

In the cooling tower according to the first aspect, the filler unit 12 has high rigidity while suppressing an increase in weight due to the partition plate 32 arranged inside the casing 31, and the vibration mass of the filler 33 is dispersed, increasing the natural frequency. Therefore, even if the cooling tower 10 vibrates due to an earthquake, the filler unit 12 and the filler 33 do not vibrate significantly, and damage to the filler 33 is suppressed. As a result, the earthquake resistance of the cooling tower 10 can be improved, and maintenance such as the installation and replacement of the filler can be easily performed.

In the cooling tower according to the second aspect, the partition plates 32 are arranged at intervals inside the casing 31 in the horizontal direction intersecting the air flow path A1, and the filler material 33 is arranged between the pair of support plates 41, 42 and the partition plates 32 and between the partition plates 32. In this way, the multiple partition plates 32 can increase the rigidity while suppressing an increase in the weight of the filler material unit 12, thereby improving earthquake resistance.

In the cooling tower according to the third aspect, the partition plate 32 is hollow. This makes it possible to suppress an increase in the weight of the partition plate 32 and to improve its rigidity.

In the cooling tower according to the fourth aspect, reinforcing members 51, 52, and 53 are arranged inside the partition plate 32. This allows the strength of the partition plate 32 to be improved by the reinforcing members 51, 52, and 53.

The cooling tower according to the fifth aspect is provided with damping members 61, 62 between the casing 31 and the partition plate 32, which dampen the displacement of the partition plate 32 relative to the casing 31. As a result, the displacement of the partition plate 32 relative to the casing 31 is damped by the damping members 61, 62, and damage to the filler material 33 can be suppressed.

In the cooling tower according to the sixth aspect, the damping members 61, 62 have a damper device installed between the support plates 41, 42 and the partition plate 32. This allows the damping members 61, 62 to be simplified.

The cooling tower according to the seventh aspect is provided with restoring members 63, 64 between the casing 31 and the partition plate 32, which restore the position of the partition plate 32 relative to the casing 31. As a result, the position of the partition plate 32 relative to the casing 31 is restored by the restoring members 63, 64, and the function of the filler material 33 can be maintained.

In the cooling tower according to the eighth aspect, the restoring members 63, 64 have springs that are installed between the support plates 41, 42 and the partition plate 32. This allows the restoring members 63, 64 to be simplified.

The cooling tower according to the ninth aspect is provided with a first friction portion 81 that attenuates the displacement of the filler 33 relative to the casing 31 due to friction generated between the casing 31 and the filler 33. As a result, when the casing 31 and the filler 33 are displaced relative to each other, the displacement is attenuated by the first friction portion 81, and damage to the filler 33 can be suppressed.

In the cooling tower according to the tenth aspect, an upper filler 83 is disposed above the casing 31, and a second friction portion 84 is provided that attenuates the displacement of the upper filler 83 relative to the casing 31 due to friction generated between the casing 31 and the upper filler 83. As a result, when the casing 31 and the upper filler 83 undergo relative displacement, the displacement is attenuated by the second friction portion 84, and damage to the upper filler 83 can be suppressed.

The filler unit according to the eleventh aspect has a casing 31 having a pair of support plates 41, 42, a partition plate 32 arranged at a distance between the pair of support plates 41, 42 inside the casing 31, and a filler 33 arranged between the pair of support plates 41, 42 and the partition plate 32. This prevents the filler unit 12 and the filler 33 from vibrating significantly when an earthquake occurs, suppressing damage to the filler 33 and improving earthquake resistance.

Note that in the above-described embodiment, the configuration of the cooling tower 10 is not limited to the embodiment, and may be set appropriately depending on the specifications, installation location, etc.
