[0063] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative in nature and is in no way intended to limit the disclosure, its application or uses. The disclosure can be implemented in numerous different forms, not just the embodiments described herein.

It should be noted that the relative arrangement of components and steps, the components of materials, numerical expressions, and numerical values set forth in these embodiments are to be interpreted as merely exemplary, rather than as a limitation unless otherwise specifically stated.

[0064] The terms "first", "second", and similar terms used in the present disclosure do not denote any order, quantity, or importance, but are used to distinguish different parts. The terms "comprise", "include" or "contain" and similar terms mean that the elements before the term encompass the elements listed after the term, and do not exclude the possibility of also encompassing other elements. "Up", "down", "left", "right", and the like are used only to indicate relative positional relationships, and when the absolute position of the described object changes, the relative positional relationship can also change accordingly.

[0066] All terms used in the present disclosure, including technical or scientific terms, have the same meanings as those understood by those having ordinary knowledge in the art to which the present disclosure pertains, unless otherwise specifically defined. It should also be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and not in an idealized or overly formal sense, unless expressly so defined herein.

[0067] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered as part of the present disclosure, where appropriate.

[0068] Cooling towers will have different working states in actual work, and the water flow of the cooling tower is about 5%-100% under standard conditions. In the related art, the water distribution plate of the cooling tower is mainly in two ways, i.e., open hole dripping and installing a spray head to spray. When the open hole dripping, the hole position is easy to be blocked. When the spray head sprays, if the liquid level is lower than the water inlet position of the spray head, all the spray heads will not spray water. The above two ways will easily cause the problems of dry blowing on the windward surface and uneven water distribution on the water distribution plate when the water flow is the lowest.

[0069] Therefore, in one aspect of the embodiments of the present disclosure, a water distribution device and a cooling tower are provided to optimize the water distribution operation.

[0070] Figure 1A is a structural schematic diagram of some embodiments of the water distribution device according to the present disclosure, Figure 1B is a structural schematic diagram of other embodiments of the water distribution device according to the present disclosure, Figure 2 is a structural schematic diagram of the water distribution assembly of the water distribution device according to the present disclosure in different water levels, referring to Figure 1A 、 1B and Figure 2 The water distribution device includes a water distribution assembly 1 and a spraying assembly 2. Figure 1A and Figure 2 The X direction in

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

[0072] ​The spraying assembly 2 comprises a water guide part 21 and a water outlet part 22 connected with the water guide part 21. The water guide part 21 is arranged in the water storage space of the water distribution assembly 1, and the water outlet part 22 is arranged outside the water distribution assembly 1. The water guide part 21 is configured to guide the water in the water storage space to the water outlet part 22, so as to be discharged outside through the water outlet part 22. The water guide part 21 is provided with a water guide hole 3 extending in the vertical direction, which is configured to guide water to the water outlet part 22 at any water level in the water storage space.

[0073] The water guide part 21 and the water outlet part 22 are arranged in sequence in the vertical direction. The water flow in the water storage space enters the water guide part 21 through the water guide hole 3, and then flows to the water outlet part 22 under the action of gravity, and is sprayed to the filler below by the water outlet part 22, so as to cool the filler. The water outlet part 22 includes but is not limited to a hole or a water guide channel to spray water to the filler.

[0074] In the embodiment, the water guide hole 3 of the water guide part 21 extends in the vertical direction and can penetrate through each height position 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 to the water outlet part 22 by the water guide part 21. Therefore, the risk of no water outlet of the water outlet part 22 can be effectively reduced, the problems of dry blowing of the windward surface of the water distribution device and uneven water distribution can be avoided, the water distribution process can be optimized, and the heat exchange capacity of the water distribution device can be 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 is a top view of some other embodiments of the water distribution assembly of the water distribution device according to the present disclosure, referring to Fig. 1 Figure 3B In some embodiments, the water distribution assembly 1 comprises a water distribution plate 11 and a partition 12.

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

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

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

[0079] The separator 12 can be integrally formed with the bottom wall of the water distribution plate 11 or be two independent components. The separator 12 subdivides the water storage space into multiple water storage units 4, which enables the water in the water storage space to flow from the water guide 21 to the water outlet 22 more quickly, thereby accelerating the water distribution speed.

[0080] The number of separators 12 can be one or more, and the spraying components 2 are disposed between the separators 12 and the inner wall of the water distribution tray 11 and / or between adjacent separators 12. The number and placement of the spraying components 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 separator 12 and the water distribution plate 11 is as follows: Figure 1A As shown by angle B, which is an obtuse angle, the cross-section of the water storage unit 4 parallel to the bottom surface of the water distribution plate 11 is larger when the water level is high and smaller when the water level is low. This results in a faster flow rate at low water levels compared to high water levels, which helps to maintain a balanced water spray volume per unit time for the spraying assembly 2 at different water levels. The separator 12 can be configured as a frustum, cone, or other shapes.

[0082] In this embodiment, by setting a partition 12 in the water storage space with a side wall forming an obtuse angle with the bottom wall of the water distribution plate 11, each water storage unit 4 can accumulate water level more quickly to start the operation of spraying water outward, and submerge the water guide section 21 more quickly to achieve full water output operation, and allow the water outlet section 22 to maintain a relatively 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 separator 12 is frustum-shaped, and the top end face of the separator 12 is parallel to the bottom wall of the water distribution plate 11. In this embodiment, by setting the separator 12 to a frustum shape, each water storage unit 4 can supply water more evenly through the water guide within a unit time at different water storage levels, thereby improving the ability to distribute water evenly.

[0084] refer to Figure 1B , Figure 3B In some embodiments, all sidewalls of the partition 12 are spaced apart from the sidewalls of the water distribution tray 11 to allow the multiple water storage units 4 to be connected. The partition 12 can be fixedly installed on the bottom wall of the water distribution tray 11, and there are gaps around the partition 12 and the inner wall of the water distribution tray 11, so there is no direct contact. In this case, the water in the entire water storage space is connected.

[0085] In the embodiment, by making the partition 12 not abut against the inner wall of the water distribution tray 11, the water distribution in each water storage unit 4 can be uniform, the liquid level of the entire water storage space is balanced, the water pressure of each water outlet is the same, and the situation that the liquid level of the water storage unit 4 close to the water outlet 6 of the cooling tower is high and the liquid level of the water storage unit 4 farthest from the water outlet 6 of the cooling tower is too low to stop water distribution in advance can be avoided, so that the water distribution between each water storage unit 4 can be close to the water amount, which helps to make the water distribution operation more reliable and uniform.

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

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

[0088] The plurality of partitions 12 can be equidistantly arranged in the water distribution tray 11 along the first direction, the two side walls of the partition 12 inclined along the first direction are respectively at an obtuse angle with the bottom wall of the water distribution tray 11, and the partition 12 has no gap with the side wall of the water distribution tray 11 in the second direction, so as to separate the water storage space into a plurality of independent water storage units 4.

[0089] The partition 12 can be integrally formed with the water distribution tray 11, the partition 12 is upwardly protruded 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 is inwardly recessed at a position corresponding to the partition 12.

[0090] The top of the partition 12 can be provided with a plurality of water distribution holes 120, when the water level of the water distribution tray 11 is higher than the top of the partition 12, water can be discharged outwardly at the water distribution holes 120, so as to cooperate with the water outlet part 22 to realize mixed water distribution.

[0091] In the embodiment, by separating 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 distribution state faster and the water does not overflow, so that each spray assembly 2 close to the water outlet 6 of the cooling tower can be in the full water distribution state at all times.

[0092] Figure 4A is a structural schematic view 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 4Cis a top view of some embodiments of the spraying assembly of the water distribution device according to the present disclosure, 5A is a structural schematic view of some embodiments of the water guide part 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 Figures 4A-5C In some embodiments, the water guide part 21 is in a hollow cylindrical shape. The water guide hole 3 includes a first water guide hole 31, which is in a spiral shape and extends along the vertical direction and the circumferential direction of the water guide part 21 respectively from the top of the water guide part 21 to the bottom of the water guide part 21.

[0093] The water guide part 21 is internally formed in a hollow cylindrical pipe so that the water in the water storage unit 4 flows downward along the cylindrical pipe to the water outlet part 22. The first water guide hole 31 can be provided in a spiral shape and gradually extends along the vertical direction and the circumferential direction of the water guide part 21, and penetrates from the top of the water guide part 21 to the bottom of the water guide part 21.

[0094] In this embodiment, by providing the first water guide hole 31 extending from the top of the water guide part 21 to the bottom of the water guide part 21 in a spiral shape, in the case that the height and width of the orifice are equal, the area changes less when the liquid level drops by the same height, and under the same cooling tower outlet flow, the water level formed is higher, which can increase the inflow velocity under the same water level, thereby improving the water guide speed of the water guide part 21, making the water outlet disc 220 rotate faster, and the water distribution area larger, which helps to improve the water distribution efficiency.

[0095] With reference to Figures 4A-5C In some embodiments, the water guide part 21 is in a hollow cylindrical shape. 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 in a spiral shape and extends along the vertical direction and the circumferential direction of the water guide part 21 to the bottom of the water guide part 21.

[0096] The second water guide hole 32 is located above the first water guide hole 31 along the vertical direction, and the second water guide hole 32 extends along the circumferential direction of the water guide part 21. The number of second water guide holes 32 can be multiple and are arranged at intervals along the circumferential direction of the water guide part 21.

[0097] In this embodiment, the second water guide hole 32 changes more when the liquid level drops by the same height, and the water guide speed of the second water guide hole 32 is lower than that of the first water guide hole 31. By arranging the second water guide hole 32 above the starting point of the first water guide hole 31, 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, which can keep the total amount of water sprayed by the spraying assembly 2 per unit time consistent under different water storage levels, and achieve uniform water distribution.

The spray assembly 2 further comprises a connecting piece 23 which is inserted into the center of the water outlet disc 220 and connected with the connecting seat 210 of the water guide part 21.

[0099] The bottom of the water guide part 21 can be provided with the connecting seat 210, which can be a hollow structure, and a connecting hole 211 for plugging with the connecting piece 23 is arranged at the center, and a support structure can be arranged around the connecting hole 211 to lap the outer periphery of the connecting seat 210.

[0100] The center of the water outlet disc 220 can be provided with a center hole 221 for plugging with the connecting piece 23. The outer periphery of the connecting seat 210 can be provided as a reduced structure to be inserted into the mounting hole 110 of the water distribution disc 11.

[0101] During installation, the connecting seat 210 can be first clamped into the mounting hole 110, and then the connecting piece 23 is inserted into the connecting hole 211 in the center of the connecting seat 210 through the center hole 221 of the water outlet disc 220 by interference fit.

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

[0111] In the embodiment, the water discharged through the water guide channel 52 can provide a tangential force to the water outlet disc 220 to push the water outlet disc 220 to rotate and drive the water flow to spray a larger area. The water guide channel 52 cooperates with the first water outlet hole 51 to realize multi-level water distribution in different areas.

[0112] Figure 7C are partial sectional views of other embodiments of the water outlet part of the water distribution device according to the present disclosure, with reference to Figure 4A 、 4C , 7A and 7C, in some embodiments, the water outlet disc 220 further has a plurality of second water outlet holes 53 arranged along the circumference, and the water guide direction of the second water outlet hole 53 forms an angle with the vertical direction.

[0113] The second water outlet hole 53 is away from the center of the water outlet disc 220 compared with the first water outlet hole 51, and the projection of the outer wall of the water guide part 21 on the plane of the water outlet disc 220 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 a fan-shaped hole arranged on the water outlet disc 220 from top to bottom, and the water guide direction of the second water outlet hole 53 is inclined from inside to outside along the radial direction of the water outlet disc 220, which is arranged at a slope with the plane of the water outlet disc 220, so that the water flow can fly out to a larger range when passing through, and contact with a larger area of filler.

[0115] The projection range of the second water outlet hole 53 on the water distribution tray 220 plane can be set to be greater 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 guide channels 52. The number of the second water outlet hole 53 includes but is not limited to the same number as the first water outlet hole 51.

[0116] In the embodiment, the second water outlet hole 53 is arranged to cooperate with the first water outlet hole 51 to form multi-stage water distribution, so as to realize water distribution in a larger area and more levels of water distribution operation. The projection of the water guide part 21 between the first water outlet hole 51 and the second water outlet hole 53 can ensure that the water can flow through all the water distribution areas after leaving the water distribution tray 220, and the excess water enters from the water guide channel 52, so as to fully utilize the water flow energy.

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

[0118] The water guide edge body 223 is a region wrapped around the water outlet body 222, and the water guide edge body 223 and the water outlet body 222 can be integrally formed. The water guide edge body 223 is lower than the water outlet body 222 to form a stepped structure in the vertical direction. The water guide edge body 223 and the water outlet body 222 can be connected by an inclined slope.

[0119] In the embodiment, the edge of the water distribution tray 220 is set to be lower than the center of the slope structure, which is conducive to guiding the water flow outside the water distribution tray 220, so as to realize multi-level water distribution on the water distribution tray 220, make the water flow more uniform, and distribute the water flow on the filler in a larger range, speed up the evaporation process, and improve the cooling efficiency.

[0120] Reference Figure 4A 、 4C and 7A, in some embodiments, the cooling water sprayed from the cooling tower water outlet 6 falls on the water distribution tray 11, and the water is stored in the center area of the water distribution tray 11 first, then spreads to both sides, and then flows out from the top water distribution hole 120.

[0121] When the water level in the central region of the water distribution plate 11 reaches the height of the second water guide hole 32 of the water guide part 21, water flows in from the first water guide hole 31 and flows to the water outlet part 22 to start spraying water outward. When the water level 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 fully filled, and all the water outlet parts 22 spray water outward.

[0122] Figure 8A is a structural schematic diagram of some embodiments of a cooling tower according to the present disclosure, Figure 8B is a structural schematic diagram of some other embodiments of a cooling tower according to the present disclosure, Figure 8C is a structural schematic diagram of yet some other embodiments of a cooling tower according to the present disclosure, with reference to Figures 8A-C In another aspect of the embodiments of the present disclosure, a cooling tower is provided, which comprises the water distribution device of any one of the above and a cooling tower water outlet 6 configured to supply water to the water distribution assembly 1.

[0123] In the embodiments, the water distribution device can avoid the problems of dry blowing on the windward side of the water distribution device and uneven water distribution, optimize the water distribution process, and achieve more consistent and uniform water distribution for the filler, which helps to improve the cooling capacity of the cooling tower.

[0124] With reference to Figure 8A and Figure 8B In some embodiments, the cooling tower water outlet 6 is arranged above the water storage unit 4 located in the middle of the water distribution plate 11 among the plurality of water storage units 4. When only one cooling tower water outlet 6 is arranged, the cooling tower water outlet 6 can be arranged above the water storage unit 4 located in the middle of the water distribution plate 11 in the first direction.

[0125] In the embodiments, the cooling tower can accumulate water level faster through the partition 12 to start the operation of spraying water outward and achieve full water outlet operation faster. Under different water supply flow rates of the cooling tower, the water outlet part 22 can maintain a relatively balanced water distribution flow rate. Even if the water outlet flow rate of the cooling tower is at the lowest working condition of 5%, the water outlet part 22 located below the cooling tower water outlet 6 can still have water entering and be in a normal water spraying state, preventing the simultaneous water stop of all water outlet parts 22, avoiding the dry blowing phenomenon on the windward side of the cooling tower, and ensuring the heat exchange performance of the cooling tower.

[0126] With reference to Figure 8C In some embodiments, the number of cooling tower water outlets 6 is multiple, and each cooling tower water outlet 6 is 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 outlet 6 corresponds to the water storage unit 4 one by one.

[0127] In this embodiment, multiple cooling tower water outlets 6 matched with the water storage units 4 are arranged, which can realize uniform water distribution in each water storage unit 4, avoid the situation that the water level of the water storage units close to the middle is high, the water level of the water storage units on both sides is too low, and the water storage units at the farthest end stop water distribution in advance during the low flow operation of the cooling tower, and can guarantee the uniformity of water distribution.

[0128] Reference Figure 2 In some embodiments, the multiple water storage units 4 are independent of each other. When the water level is above C1 in FIG. 6, the cooling tower water outlet flow is 100%-80% under standard conditions, the water distribution holes 120 of the partition 12 and the water outlet portion 22 are mixed as a whole to distribute water, and at this time, the maximum water outlet area is achieved. Figure 2

[0129] When the water level is lowered to between C1 and C2, i.e., the cooling tower flow is between 80% and 50%, the water distribution holes 120 of the partition 12 do not distribute water, the water outlet area is reduced, and the water level is stably fluctuated between C1 and C2.

[0130] When the water level is lowered to between C2 and C3, i.e., the cooling tower flow is between 50% and 30%, the water distribution area of the second water guide hole 32 of the water guide portion is uniformly changed to achieve uniform water distribution and control the water level to fluctuate between the two.

[0131] When the water level is lowered to between C3 and C4, the cooling tower flow is between 30% and 5%. The area of the first water guide hole 31 is uniformly changed to achieve uniform water distribution.

[0132] For different flows of the cooling tower, the water level is stable at each stage to ensure the stability of the water distribution area of the water outlet portion 22.
