[0067] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0068] The cooling tower will have different working conditions during actual operation. The water flow rate of the cooling tower is about 5%-100% under standard conditions. In the related technology, the water distribution tray of the cooling tower is mostly divided into two types: perforated dripping and installed nozzle spraying. When perforated dripping is used, the hole is easy to be blocked. When the nozzle is spraying, if the liquid level is lower than the water inlet position of the nozzle, all nozzles will not discharge water. The above two types are prone to dry blowing on the windward side and uneven water distribution on the water distribution tray when the water flow rate is the lowest.

[0069] In view of this, in one aspect of an embodiment of the present disclosure, a water distribution device and a cooling tower are provided, which are used in a cooling tower and can optimize the water distribution operation.

[0070] Figure 1A is a schematic diagram of the structure of some embodiments of the water distribution device according to the present disclosure, Figure 1B is a schematic structural diagram of some other embodiments of the water distribution device according to the present disclosure, Figure 2 is a schematic diagram of the structure of the water distribution components of the water distribution device of the present disclosure at different water levels, with reference to Figure 1A , 1B and Figure 2 The water distribution device includes a water distribution component 1 and a spraying component 2. Figure 1A and Figure 2 The X direction is the vertical direction.

[0071] The water distribution assembly 1 has a water storage space, such as Figure 1B In A, the water storage space is configured to accommodate water supply from the cooling tower. When the cooling tower supplies water at different water volumes, different water levels will appear in the water storage space, such as Figure 2 C1~C4 in the.

[0072] The spray assembly 2 includes a water guide 21 and a water outlet 22 connected to the water guide 21. The water guide 21 is arranged in the water storage space of the water distribution assembly 1, and the water outlet 22 is arranged outside the water distribution assembly 1. The water guide 21 is configured to guide the water in the water storage space to the water outlet 22 so as to discharge water outward through the water outlet 22. The outer periphery of the water guide 21 is provided with a water guide hole 3 extending in a vertical direction, and the water guide hole 3 is configured to guide water to the water outlet 22 when the water storage space is at any water level.

[0073] The water guide part 21 and the water outlet part 22 are arranged in sequence along the vertical direction. After the water in the water storage space enters the water guide part 21 through the water guide hole 3, it flows to the water outlet part 22 under the action of gravity, and is sprinkled outward from the water outlet part 22 to the filler below to cool the filler. The water outlet part 22 includes but is not limited to spraying water to the filler by opening a hole or a water diversion channel.

[0074] In this embodiment, the water guide hole 3 of the water guide part 21 extends in the vertical direction and can pass through various height positions of the water guide part 21. When the water in the water storage space is at different water levels, it can enter the water guide part 21 through the water guide hole 3, and be guided by the water guide part 21 to the water outlet part 22. Therefore, the risk of no water coming out of the water outlet part 22 can be effectively reduced, and the problems of dry blowing and uneven water distribution on the windward side of the water distribution device can be avoided, the water distribution process is optimized, and the heat exchange capacity of the water distribution device is ensured.

[0075] Figure 3A is a top view of some embodiments of the water distribution assembly of the water distribution device according to the present disclosure, Figure 3B 1 is a top view of another embodiment of the water distribution assembly of the water distribution device according to the present disclosure, with reference to FIG. Figure 3B In some embodiments, the water distribution assembly 1 includes a water distribution tray 11 and a partition 12 .

[0076] The water distribution tray 11 has side walls extending in the vertical direction and a bottom wall perpendicular to the vertical direction. The side walls of the water distribution tray 11 and the bottom wall of the water distribution tray 11 form a water storage space.

[0077] The partition 12 is disposed on the bottom wall of the water distribution tray 11 and protrudes upward relative to the bottom wall of the water distribution tray 11 to divide the water storage space into a plurality of water storage units 4. The angle formed by the side wall of the partition 12 and the bottom wall of the water distribution tray 11 is an obtuse angle. One or more spraying assemblies 2 are disposed in each water storage unit 4.

[0078] The water distribution pan 11 includes but is not limited to a cubic shape with an opening at the top, and receives water supply from the cooling tower water outlet 6 from above. The bottom wall of the water distribution pan 11 refers to the bottom inner wall surface of the water distribution pan 11, and the side walls of the water distribution pan 11 are located around the bottom wall of the water distribution pan 11 and are perpendicular to the bottom wall. The bottom wall of the water distribution pan 11 is provided with a mounting hole 110 for mounting the spray assembly 2.

[0079] The partition 12 can be integrally formed with the bottom wall of the water distribution tray 11 or be two independent components. The partition 12 subdivides the water storage space into a plurality of water storage units 4, enabling the water in the water storage space to flow more quickly from the water guide part 21 to the water outlet part 22, thereby accelerating the water distribution speed.

[0080] The number of the partitions 12 can be one or more, and the spray assembly 2 is arranged between the partition 12 and the inner wall of the water distribution tray 11 and / or between adjacent partitions 12. The number and arrangement position of the spray assembly 2 in each water storage unit 4 can be adjusted according to actual water distribution needs.

[0081] The angle formed between the side wall of the partition 12 and the water distribution tray 11 is as follows: Figure 1A As shown in the angle B in the figure, the angle B is an obtuse angle, so that the cross section of the water storage unit 4 parallel to the bottom surface of the water distribution tray 11 is large when the water level is high and small when the water level is low, so that the flow rate when the water level is low is faster than when the water level is high, which is conducive to keeping the water spraying amount of the spray assembly 2 per unit time balanced at different water levels. The partition 12 can be set to a prism shape, a cone or other shapes.

[0082] In this embodiment, by arranging a partition 12 in the water storage space with a side wall that forms an obtuse angle with the bottom wall of the water distribution tray 11, each water storage unit 4 can accumulate water level more quickly to start the operation of sprinkling water outward, and submerge the water guide part 21 more quickly to achieve full water outlet operation, and allow the water outlet part 22 to maintain a more balanced and reliable water distribution under different water supply flow rates of the cooling tower.

[0083] Refer to Figure 1~ Figure 3B In some embodiments, the partition 12 is in a prism shape, and the top end surface of the partition 12 is parallel to the bottom wall of the water distribution tray 11. In this embodiment, by setting the partition 12 in a prism shape, each water storage unit 4 can supply water to the outside more evenly through the water guide part per unit time at different water storage levels, thereby improving the ability of even water distribution.

[0084] refer to Figure 1B , Figure 3B In some embodiments, all side walls of the partition 12 are spaced apart from the side walls of the water distribution tray 11 to allow the plurality of water storage units 4 to be connected. The partition 12 can be fixedly disposed on the bottom wall of the water distribution tray 11, and the partition 12 has a gap around the inner wall of the water distribution tray 11 without direct contact, and the water in the entire water storage space is connected.

[0085] In the present embodiment, by making the partition 12 not abut against the inner wall of the water distribution tray 11, it is possible to achieve uniform water distribution in each water storage unit 4, balance the liquid level in the entire water storage space, and make the water pressure in each water outlet the same, thereby avoiding the situation in which the water storage unit 4 close to the cooling tower water outlet 6 has a high liquid level and the water storage unit 4 farthest from the cooling tower water outlet 6 has a too low liquid level during the low-flow operation of the cooling tower, thus stopping the water distribution in advance. This allows water to be distributed between each water storage unit 4 with a relatively close water volume, which helps to make the water distribution operation more reliable and uniform.

[0086] refer to Figure 1A , Figure 2 and Figure 3A In some embodiments, two opposite side walls of the partition 12 are respectively connected to the side walls of the water distribution tray 11 so that the multiple water storage units 4 are independent of each other. The top of the partition 12 is higher than the top of the water guide 21.

[0087] The water distribution tray 11 includes but is not limited to extending along the first direction and the second direction. Figure 1A The Y direction is the first direction, and the Z direction is the second direction, and both the first direction and the second direction are perpendicular to the vertical direction.

[0088] Multiple partitions 12 can be arranged in the water distribution tray 11 at equal intervals along the first direction. The two side walls of the partition 12 inclined along the first direction form obtuse angles with the bottom wall of the water distribution tray 11 respectively, and there is no gap between the partition 12 and the side wall of the water distribution tray 11 in the second direction, thereby dividing the water storage space into multiple independent water storage units 4.

[0089] The partition 12 can be integrally formed with the water distribution tray 11 . The partition 12 protrudes upward relative to the bottom wall of the water distribution tray 11 , and the outer side of the bottom wall of the water distribution tray 11 corresponding to the partition 12 is recessed inward.

[0090] A plurality of water distribution holes 120 may be provided at the top of the partition 12 . When the water level of the water distribution tray 11 is higher than the top of the partition 12 , water may flow outward from the water distribution holes 120 , so as to cooperate with the water outlet 22 to achieve mixed water distribution.

[0091] In this embodiment, by dividing the water storage space into a plurality of independent water storage units 4 and making the top of the partition 12 higher than the top of the water guide part 21, the water guide part 21 can reach the full water spraying state more quickly without water overflowing, so that each spraying assembly 2 close to the cooling tower water outlet 6 can always be in the full water spraying state.

[0092] Figure 4A is a schematic diagram of the structure of some embodiments of the spray assembly of the water distribution device according to the present disclosure, Figure 4B is a side view of some embodiments of the spray assembly of the water distribution device according to the present disclosure, Figure 4C5A is a schematic diagram of the structure of some embodiments of the water distribution device according to the present disclosure. Figure 5B is a side view of some embodiments of the water guide part of the water distribution device according to the present disclosure, Figure 5C is a bottom view of some embodiments of the water guide part of the water distribution device according to the present disclosure, with reference to Figure 4A to Figure 5C In some embodiments, the water guide portion 21 is hollow cylindrical. The water guide hole 3 includes a first water guide hole 31, which is spiral and extends from the top of the water guide portion 21 to the bottom of the water guide portion 21 along the vertical direction and the circumferential direction of the water guide portion 21.

[0093] A hollow cylindrical pipe is formed inside the water guide part 21 so that water in the water storage unit 4 flows down along the cylindrical pipe to the water outlet 22. The first water guide hole 31 can be set to be spiral, gradually extending along the vertical direction and the circumferential direction of the water guide part 21, and passing through the top of the water guide part 21 to the bottom of the water guide part 21.

[0094] In this embodiment, by providing a first water guide hole 31 that spirally extends from the top of the water guide part 21 to the bottom of the water guide part 21, when the height and width of the hole are equal, the area change is smaller when the liquid level drops by the same height. Under the same cooling tower outlet flow rate, the formed water level is higher, which can increase the water inlet flow rate at the same water level, thereby increasing the water guide speed of the water guide part 21, making the water outlet plate 220 rotate faster, and the water sprinkling area is larger, which helps to improve the water distribution efficiency.

[0095] refer to Figure 4A to Figure 5C In some embodiments, the water guide portion 21 is hollow cylindrical. The water guide hole 3 includes a first water guide hole 31 and a second water guide hole 32. The first water guide hole 31 is spiral, extending to the bottom of the water guide portion 21 along the vertical direction and the circumferential direction of the water guide portion 21 respectively.

[0096] The second water guide hole 32 is located above the first water guide hole 31 in the vertical direction and extends along the circumferential direction of the water guide portion 21. There can be a plurality of second water guide holes 32, which are arranged at intervals along the circumferential direction of the water guide portion 21.

[0097] In this embodiment, the area of ​​the second water guide hole 32 changes more when the liquid level drops to the same height, and the water guide speed of the second water guide hole 32 is lower than the water guide speed of the first water guide hole 31. The second water guide hole 32 is arranged above the starting point of the first water guide hole 31, and water is guided through the second water guide hole 32 when the liquid level in the water storage unit 4 is high, and water is distributed through the first water guide hole 31 when the liquid level in the water storage unit 4 is low, so that the total amount of water sprayed by the spray assembly 2 at different water storage levels per unit time can be kept consistent, and uniform water distribution can be achieved.

[0098] Figure 6is a schematic diagram of the structure of some embodiments of the connecting parts of the water distribution device according to the present disclosure, referring to Figure 4A to Figure 6 In some embodiments, the water outlet 22 includes a water outlet tray 220, and the bottom of the water guide 21 has a connecting seat 210.

The connecting seat 210 may be a hollow structure with a connecting hole 211 provided at the center for plugging with the connecting piece 23 . A supporting structure may be provided around the connecting hole 211 to overlap the outer periphery of the connecting seat 210 .

[0100] A central hole 221 may be provided at the center of the water outlet tray 220 to be plugged with the connector 23. The outer periphery of the connecting seat 210 may be provided as a reduced structure to be inserted into the mounting hole 110 of the water distribution tray 11.

[0101] During installation, the connection seat 210 can be first inserted into the installation hole 110, and then the connection piece 23 can be passed through the central hole 221 of the water outlet tray 220 and inserted into the connection hole 211 at the center of the connection seat 210 through interference fit.

[0102] In this embodiment, by providing a connector 23 that is plugged into the water guide part 21 and the water outlet tray 220 respectively, the installation connection between the water guide part 21 inside the water distribution tray 11 and the water outlet part 22 outside the water distribution tray 11 can be achieved without affecting the water flow conduction, and has high structural reliability.

[0110] The starting point of the water diversion channel 52 refers to the end closer to the water outlet tray 220, and the end point of the water diversion channel 52 refers to the end away from the water outlet tray 220. The number of water diversion channels 52 can be equal to the number of first water outlet holes 51, and the starting point of the water diversion channel 52 can be opposite to the first water outlet hole 51.

[0111] In this embodiment, the water discharged through the water diversion channel 52 provides a tangential force to the water outlet tray 220, drives the water outlet tray 220 to rotate, and drives the water flow to spray a larger area. The water diversion channel 52 cooperates with the first water outlet hole 51 to achieve multi-level water distribution to different areas.

[0112] Figure 7C is a partial cross-sectional view of another embodiment of the water outlet of the water distribution device according to the present disclosure, referring to Figure 4A , 4C , 7A and 7C, in some embodiments, the water outlet tray 220 further has a plurality of second water outlet holes 53 arranged at intervals along the circumferential direction, and the diversion direction of the second water outlet holes 53 forms an angle with the vertical direction.

[0113] The second water outlet hole 53 is farther away from the center of the water outlet tray 220 than the first water outlet hole 51 , and the projection of the outer wall of the water guide 21 on the plane where the water outlet tray 220 is located is located between the first water outlet hole 51 and the second water outlet hole 53 .

[0114] The second water outlet hole 53 includes but is not limited to being arranged in a fan shape, conducting downward from the top of the water outlet tray 220, and the diversion direction of the second water outlet hole 53 is inclined from the inside to the outside along the radial direction of the water outlet tray 220, and is arranged at a slope with the plane of the water outlet tray 220, so that the water flow can splash over a larger range when passing through and contact a larger area of ​​filler.

[0115] The projection area of ​​the second water outlet hole 53 on the plane of the water outlet plate 220 can be set to be larger than the projection area of ​​the first water outlet hole 51. The second water outlet hole 53 can be connected along the axis between the starting points of two adjacent water diversion channels 52. The number of the second water outlet holes 53 includes but is not limited to being equal to the number of the first water outlet holes 51.

[0116] In this embodiment, the second water outlet hole 53 is provided to cooperate with the first water outlet hole 51 to form a multi-level water distribution, so as to achieve water sprinkling in a larger area and a more multi-level water sprinkling operation. The projection of the water guide 21 is between the first water outlet hole 51 and the second water outlet hole 53, so that the water can flow through all water distribution areas after being retained in the water outlet tray 220, and the excess water enters from the water guide channel 52, so as to make full use of the kinetic energy of the water.

[0117] refer to Figure 4A , 4C 7A, in some embodiments, the water outlet plate 220 includes a water outlet body 222 and a water diversion edge body 223. The first water outlet hole 51, the starting point of the water diversion channel 52 and the second water outlet hole 53 are arranged on the water outlet body 222, the water diversion edge body 223 surrounds the outer periphery of the water outlet body 222, the height of the top of the water diversion edge body 223 is lower than the height of the top of the water outlet body 222, and the height of the top of the water diversion edge body 223 gradually decreases from the inside to the outside along the radial direction.

[0118] The water diversion edge body 223 is a region surrounding the water outlet body 222, and the water diversion edge body 223 and the water outlet body 222 can be integrally formed. The water diversion edge body 223 is lower than the water outlet body 222 to form a step shape in the vertical direction. The water diversion edge body 223 and the water outlet body 222 can be connected through an inclined slope.

[0119] In this embodiment, the edge of the water outlet tray 220 is set to a slope structure lower than the center, which is conducive to diverting water to the outside of the water outlet tray 220, so as to achieve multi-level water distribution on the water outlet tray 220, so that the water flow is more evenly and distributed on the filler over a larger range, thereby accelerating the evaporation process and improving the cooling efficiency.

[0120] refer to Figure 4A , 4C As shown in FIG. 7A , in some embodiments, the cooling water sprayed from the cooling tower outlet 6 falls onto the water distribution tray 11 , and is first filled with water in the water storage unit 4 in the central area of ​​the water distribution tray 11 , and then diffuses to both sides and flows out from the top water distribution hole 120 .

[0121] When the water level in the center area of ​​the water distribution tray 11 reaches the height position of the second water guide hole 32 of the water guide part 21, water flows into the first water guide hole 31, flows to the water outlet 22 and starts to sprinkle water outward. When the water level then rises to the second water guide hole 32, the water inlet area becomes larger, and more water flows in until the water guide part 21 is completely filled, and all the water outlets 22 sprinkle water outward.

[0122] Fig. 8A is a schematic diagram of the structure of some embodiments of the cooling tower according to the present disclosure, Figure 8B is a schematic structural diagram of some other embodiments of the cooling tower according to the present disclosure, Figure 8C is a schematic diagram of the structure of some other embodiments of the cooling tower according to the present disclosure, referring to Figures 8A to 8C In another aspect of an embodiment of the present disclosure, a cooling tower is provided, comprising a water distribution device as described above and a cooling tower water outlet 6 , wherein the cooling tower water outlet 6 is configured to supply water to the water distribution assembly 1 .

[0123] In this embodiment, the water distribution device can avoid the problems of dry blowing and uneven water distribution on the windward side of the water distribution device, optimize the water distribution process, achieve more continuous and uniform water distribution to the filler, and help improve the cooling capacity of the cooling tower.

[0124] refer to Fig. 8A and Figure 8B In some embodiments, the cooling tower water outlet 6 is disposed above the water storage unit 4 located in the middle of the water distribution tray 11 among the multiple water storage units 4. When only one cooling tower water outlet 6 is provided, the cooling tower water outlet 6 can be disposed above the water storage unit 4 located in the middle of the water distribution tray 11 along the first direction.

[0125] In this embodiment, the cooling tower can accumulate water level faster through the partition 12 to start the operation of sprinkling water outward, and achieve full water discharge operation faster. Under different water supply flow rates of the cooling tower, the water outlet 22 can maintain a relatively balanced water distribution flow rate. Even if the water outlet flow rate of the cooling tower is 5% under the lowest working condition, it can ensure that the water outlet 22 located below the water outlet 6 of the cooling tower always has water entering and is in a normal water sprinkling state, preventing all water outlets 22 from stopping water at the same time, avoiding dry blowing on the windward side of the cooling tower, and ensuring the heat exchange performance of the cooling tower.

[0126] refer to Figure 8C In some embodiments, there are multiple cooling tower water outlets 6, and each cooling tower water outlet 6 is respectively arranged above each water storage unit 4. The number of cooling tower water outlets 6 can match the number of water storage units 4, and the cooling tower water outlets 6 and the water storage units 4 store water in a one-to-one correspondence.

[0127] In this embodiment, a plurality of cooling tower water outlets 6 matching the water storage units 4 are provided to achieve uniform water distribution in each water storage unit 4, thereby avoiding the situation in which the liquid level of the water storage unit 4 near the middle is high and the liquid level of the water storage units 4 on both sides is too low during the low-flow operation of the cooling tower, causing the farthest water storage unit 4 to stop distributing water in advance, thereby ensuring the uniformity of water distribution.

[0128] refer to Figure 2 In some embodiments, the multiple water storage units 4 are independent of each other. Figure 2 Above C1, the water outlet flow rate of the cooling tower is 100%-80% of that under standard conditions, and the water distribution holes 120 of the partition 12 and the water outlet part 22 are mixed and distributed as a whole, and the water outlet area is the maximum at this time.

[0129] When the water level drops to between C1 and C2, that is, the cooling tower flow rate is between 80% and 50%, the water distribution holes 120 of the partition 12 do not discharge water, and the water outlet area is reduced, so that the water level is stabilized to fluctuate between C1 and C2.

[0130] When the water level drops to between C2 and C3, that is, when the cooling tower flow is between 50% and 30%, the water guide area of ​​the second water guide hole 32 of the water guide part changes evenly to achieve uniform water distribution and control the water level to fluctuate between the two.

[0131] When the water level drops to between C3 and C4, the cooling tower flow rate is between 30% and 5%. The uniform water distribution is achieved by uniformly changing the area of ​​the first water guide hole 31.

[0132] For different flow rates of the cooling tower, the water level is stable in each stage, ensuring that the spraying area of ​​the water outlet 22 is stable.
