Description
Technical Field
[0001] This invention relates to the field of cooling towers, and more specifically to a centrifugal crossflow cooling tower. Background Technology
[0002] Cooling towers, which utilize the heat exchange between water and air to lower water temperature, are widely used in industrial circulating water systems and other fields. Existing cooling towers include a tower body with an air inlet at the bottom and an air outlet at the top. A fan is installed at the air outlet. During operation, the fan draws air from the ambient environment from the inlet to the outlet, where it exchanges heat with the water sprayed by the water distribution system to lower the water temperature. However, in hot summers, the high ambient temperature often results in poor water cooling, limiting the applicable temperature range of existing cooling towers and failing to meet industry requirements.
[0003] To address these issues, improved cooling towers have recently emerged in the industry. These towers incorporate secondary temperature control devices within the tower body, allowing for secondary temperature regulation of the water during summer use to meet temperature reduction requirements under varying ambient temperatures. However, to ensure effective secondary cooling, the water undergoes a certain amount of cooling time within the secondary temperature control device. In spring and autumn, while the water flow does not require secondary temperature regulation, it still passes through the device and consumes a corresponding amount of cooling time, thus impacting the efficiency of the cooling tower during these seasons. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a centrifugal cross-flow cooling tower that can meet the temperature drop requirements of more different ambient temperatures, thereby expanding its applicable ambient temperature range and improving the efficiency of the cooling tower in spring and autumn.
[0005] The objective of this invention is achieved through the following technical solution: A centrifugal crossflow cooling tower includes a tower body, an air supply device, a packing assembly, a water distribution system, and an adjustment component. The lower end of the tower body has an air inlet, and the side of the tower body has an air outlet. The air supply device draws air from the air inlet towards the air outlet. The packing assembly is located along the path of the airflow within the tower body. The water distribution system is positioned above the packing assembly and sprays water towards it. The adjustment component is located below the packing assembly and includes an adjustment seat and a drive device. The adjustment seat has a guide channel and a secondary temperature regulating channel for adjusting the water temperature. The guide channel extends along the height of the adjustment seat and penetrates its top and bottom surfaces. The drive device drives the adjustment seat to move between a first position where the guide channel faces the packing assembly and a second position where the secondary temperature regulating channel faces the packing assembly. A receiving groove is also provided below the adjustment seat within the tower body.
[0006] The guide groove and the secondary temperature regulating groove are arranged in a circle around the central axis of the regulating seat; the driving device is used to drive the regulating seat to rotate between the first position and the second position around the central axis of the regulating seat.
[0007] The secondary temperature regulating tank is equipped with a temperature regulating pipe, which is used to supply the temperature regulating medium.
[0008] The temperature regulating pipe is spiral-shaped, and the spiral centerline of the temperature regulating pipe is aligned with the height direction of the regulating seat.
[0009] A water collector is installed at the air outlet of the tower.
[0010] The water distribution system includes a main inlet pipe, branch inlet pipes connected to the main inlet pipe, a water distribution unit, and a water distribution basin. A regulating valve is installed on the branch inlet pipe. The water distribution unit includes an inlet flange connected to the branch inlet pipe, a water distributor located below and connected to the inlet flange, and a countersink. A water distribution chamber is formed within the water distributor. The countersink is located at the lower end of the water distribution chamber, and an overflow chamber is formed within the countersink. The overflow chamber receives water flowing down through the water distribution chamber. The inner bottom wall of the overflow chamber has an upwardly protruding convex wall. A water outlet device with the water outlet direction facing the water distribution basin is provided between the countersink and the side wall of the water distribution chamber. Several spray nozzles are provided at the bottom of the water distribution basin.
[0011] From the upper end to the lower end of the water distribution chamber, the cross-sectional area of the water distribution chamber gradually increases.
[0012] The overflow chamber is equipped with a lifting plate device that can be raised and lowered.
[0013] The lifting plate device includes a lifting plate that slides and seals against the inner wall of the overflow chamber, and the lifting plate is driven to rise and fall by a lifting drive component.
[0014] The air supply device is a centrifugal blower.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a centrifugal crossflow cooling tower, which combines a tower body, an air supply device, a packing assembly, a water distribution system, and an adjustment component. The adjustment component utilizes an adjustment seat and a drive device. In summer, the drive device rotates the adjustment seat to a second position, allowing secondary cooling of the water through a secondary temperature-regulating tank. This improves the cooling tower's temperature reduction effect during summer use, thus meeting temperature reduction requirements in a wider range of ambient temperatures and expanding its applicable temperature range. Furthermore, in spring and autumn, the drive device rotates the adjustment seat to a first position, allowing water flowing from the packing assembly to flow directly through a guide channel to a receiving tank, eliminating the need for secondary cooling and saving time. This reduces the water's travel time within the cooling tower, improving its efficiency during these seasons. Additionally, a well-designed water distribution system significantly reduces inlet water pressure, minimizing damage to the water distribution basin caused by hot water impact, and effectively extending the system's lifespan.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0018] like Figure 1-12As shown, a centrifugal crossflow cooling tower includes a tower body 110, an air supply device 120, a packing assembly 150, a water distribution system 200, and an adjustment component 300. The lower end of the tower body 110 has an air inlet 112, and the side of the tower body 110 has an air outlet 111. The air supply device 120 draws airflow from the air inlet 112 towards the air outlet 111. The packing assembly 150 is located along the path of the airflow within the tower body 110. The water distribution system 200 is positioned above the packing assembly 150 and sprays water towards the packing assembly 150. The adjustment component 300 is located within the packing assembly. Below component 150, there is an adjusting seat 310 and a driving device 320; the adjusting seat 310 is provided with a guide channel 311 and a secondary temperature regulating channel 312 for regulating the water temperature; the guide channel 311 extends along the height direction of the adjusting seat 310 and penetrates the top and bottom surfaces of the adjusting seat 310; the driving device 320 is used to drive the adjusting seat 310 to move between a first position in which the guide channel 311 is aligned with the packing assembly 150 and a second position in which the secondary temperature regulating channel 312 is aligned with the packing assembly 150; a receiving groove 140 located below the adjusting seat 310 is also provided inside the tower body 110.
[0019] When used in spring and autumn, the drive device 320 drives the adjustment seat 310 to move to the first position, the air supply device 120 works and draws the outside air from the air inlet 112 to the air outlet 111. During this process, the hot water sprayed on the packing assembly 150 by the water distribution system 200 exchanges heat with the air flowing through the packing assembly 150 to reduce the water temperature. The water after exchanging heat with the air then flows through the guide channel 311 of the adjustment seat 310 to the receiving channel 140 in the tower body 110. When used in the hot summer, the drive device 320 drives the adjusting seat 310 to the second position, the air supply device 120 works and draws outside air from the air inlet 112 to the air outlet 111. During this process, the hot water sprayed on the packing assembly 150 by the water distribution system 200 first exchanges heat with the air flowing through the packing assembly 150, and then flows to the secondary temperature regulating tank 312 of the adjusting seat 310 for secondary cooling. The water that has undergone secondary cooling then flows to the receiving tank 140 in the tower body 110. Therefore, the centrifugal crossflow cooling tower provided by the present invention, by combining the tower body 110, the air supply device 120, the packing assembly 150, the water distribution system 200, and the adjusting assembly 300, and by reasonably setting the adjusting seat 310 of the adjusting assembly 300 and the drive device 320, can effectively cool the air in hot weather. During hot summer use, the drive device 320 can be used to drive the regulating seat 310 to rotate to the second position, and the water can be cooled a second time through the secondary temperature regulating tank 312. This secondary cooling can compensate for the insufficient heat exchange energy between the hot water and the outside wind, thereby improving the cooling effect of the cooling tower during summer use and meeting the temperature reduction requirements of more different ambient temperatures, thus expanding its applicable ambient temperature range. Moreover, during spring and autumn use, the drive device 320 can be used to drive the regulating seat 310 to rotate to the first position, so that the water flowing out of the packing assembly 150 can directly flow through the guide channel 311 to the receiving tank 140. This eliminates the need for the water flowing out of the packing assembly 150 to pass through the secondary temperature regulating tank 312 again, thus saving the water's running time in the cooling tower and improving the efficiency of the cooling tower during spring and autumn.
[0020] The guide slot 311 and the secondary temperature regulating slot 312 are arranged in a circle around the central axis of the adjusting seat 310; the driving device 320 is used to drive the adjusting seat 310 to rotate between a first position and a second position around the central axis of the adjusting seat 310. By reasonably setting the arrangement of the guide slot 311 and the secondary temperature regulating slot 312, the adjusting seat 310 can be easily driven to the first position or the second position.
[0021] Preferably, the secondary temperature regulating tank 312 is provided with a temperature regulating pipe 330, through which a temperature regulating medium flows. Specifically, the temperature regulating pipe 330 is spiral-shaped, and the spiral centerline of the temperature regulating pipe 330 is aligned with the height direction of the regulating seat 310. In use, a temperature regulating medium such as coolant can be introduced into the temperature regulating pipe 330. The water flowing into the secondary temperature regulating tank 312 can exchange heat with the temperature regulating medium in the temperature regulating pipe 330 to achieve secondary cooling of the water.
[0022] Preferably, the adjusting seat 310 includes a main seat body 340 and a bottom cover 350; the secondary temperature regulating groove 312 and the guide groove 311 are both disposed on the main seat body 340. The main seat body 340 includes an annular wall 341 and a lower wall 342 disposed at the bottom end of the annular wall 341. The lower end of the guide groove 311 passes through the lower wall 342. The lower wall 342 is provided with an outlet 343 that communicates with the secondary temperature regulating groove 312 and faces the receiving groove 140. The bottom cover 350 is movably installed on the main seat body 340 and is used to close the outlet 343. Specifically, a first guide rod 344 and a second guide rod 345 extending along the height direction of the adjusting seat 310 are fixed on the lower wall 342. The bottom cover 350 is movably fitted on the first guide rod 344 and the second guide rod 345. Springs 346 are installed between the bottom cover 350 and the bottom end of the first guide rod 344, and between the bottom cover 350 and the bottom end of the second guide rod 345. The springs 346 are used to provide elastic force to cause the bottom cover 350 to move toward the lower wall 342. During use, the water flowing down from the packing assembly 150 flows into the secondary temperature regulating tank 312, where it exchanges heat with the temperature regulating medium in the temperature regulating pipe 330 to achieve secondary cooling. When the water flowing into the secondary temperature regulating tank 312 overcomes the elastic force of the spring 346 and pushes the bottom cover 350 downward, the outlet 343 loses its sealing effect and becomes open. The water in the secondary temperature regulating tank 312 can flow to the receiving tank 140 through the outlet 343. Due to the high flow rate of the water in the secondary temperature regulating tank 312 through the outlet 343... The water flow rate into the secondary temperature regulating tank 312 is greater than that of the packing assembly 150. When the outlet 343 is opened, the water in the secondary temperature regulating tank 312 flows out rapidly, causing the water in the secondary temperature regulating tank 312 to gradually decrease. Under the elastic force of the spring 346, the bottom cover 350 resets towards the lower wall 342 and closes the outlet 343, allowing the water flowing into the secondary temperature regulating tank 312 to remain in the secondary temperature regulating tank 312 and continuously exchange heat with the temperature regulating medium in the temperature regulating pipe 330, and then continue to work in the above manner. By combining the main body 340 and the bottom cover 350 with the regulating seat 310, the water flowing into the secondary temperature regulating tank 312 can remain in the secondary temperature regulating tank 312 for heat exchange through the closure of the bottom cover 350, which can increase the heat exchange time between the water and the temperature regulating medium in the temperature regulating pipe 330, thereby improving the secondary temperature regulation effect.
[0023] The adjusting seat 310 is rotatably mounted inside the tower body 110. The adjusting seat 310 is provided with an outer ring 313. The driving device 320 includes a bevel gear ring 321 disposed below the outer ring 313, a bevel gear 322 meshing with the bevel gear ring 321, and a gear drive motor 323 for driving the bevel gear 322 to rotate. In use, the gear drive motor 323 operates, driving the bevel gear 322 to rotate, thereby driving the bevel gear ring 321 and the adjusting seat 310 to rotate. By adopting the above structure for the driving device 320, the adjusting seat 310 can be rotated while the position of the adjusting seat 310 can be reasonably set. Specifically, a protective cover is provided on the tower body 110, and the body of the gear drive motor 323 is fixed inside the protective cover.
[0024] A water collector 130 is installed at the air outlet 111 of the tower body 110. The air after heat exchange carries a large amount of moisture. By installing the water collector 130 at the air outlet 111 of the tower body 110, the water collector 130 can absorb the moisture in the humid air, turn the humid air into dry air, and then discharge it from the air outlet 111 of the tower body 110.
[0025] The receiving tank 140 is also connected to a drain pipe, and a drain valve is provided on the drain pipe so that when the drain valve is opened, the water in the receiving tank 140 can be discharged through the drain pipe.
[0026] The packing assembly 150 can be any packing assembly available on the market, as long as it allows water and air to flow through for heat exchange.
[0027] The air supply device 120 is a centrifugal blower. Specifically, the centrifugal blower is located outside the tower body 110, and the air outlet of the centrifugal blower is connected to the air inlet 112, so that the air from the outside environment is drawn from the air inlet 112 to the air outlet 111 by the centrifugal blower. Of course, in addition to the above, the air supply device 120 can also be any air supply device available on the market, as long as it can draw the airflow from the outside environment from the air inlet 112 to the air outlet 111.
[0028] The water distribution system 200 includes a main inlet pipe 210, a branch inlet pipe 220 connected to the main inlet pipe 210, a water distribution unit 240, and a water distribution basin 230. A regulating valve 221 is installed on the branch inlet pipe 220. The water distribution unit 240 includes an inlet flange 241 connected to the branch inlet pipe 220, a water distributor 250 located below and connected to the inlet flange 241, and a counter-support 260. A water distribution cavity 251 is formed within the water distributor 250. From the upper end to the lower end of the water distribution cavity 251, the horizontal... The cross-sectional area gradually increases; the inverted support 260 is located at the lower end of the water distribution cavity 251, and an overflow cavity 261 is formed inside the inverted support 260. The overflow cavity 261 is used to receive water flowing down through the water distribution cavity 251. The inner bottom wall of the overflow cavity 261 is provided with an upwardly protruding convex wall 262. A lifting plate device 270 can also be installed in the overflow cavity 261 in a lifting manner; a water outlet device 280 with the water outlet direction facing the water distribution basin 230 is provided between the inverted support 260 and the side wall of the water distribution cavity 251; the water distribution basin 230 is provided with a plurality of spray nozzles 231.
[0029] In use, hot water from the main inlet pipe 210, connected to the external water circulation system, flows into the inlet flange 241 of the corresponding water distribution unit 240 via the inlet branch pipe 220, thus performing the first water distribution. Water flows from the inlet flange 241 to the water distribution chamber 251 of the water distributor 250. As the water flows along the water distribution chamber 251 from its upper end to its lower end, the cross-sectional area of the water distribution chamber 251 gradually increases from its upper to lower end, causing the water inlet pressure to gradually decrease, reducing energy consumption and forming a second water distribution. The water flowing down from the water distribution chamber 251 enters the overflow chamber 261. The water is buffered by the uneven structure of the overflow chamber 261 and the convex wall 262. The water inlet pressure is reduced again, and the energy consumption is reduced again. The water overflowing from the overflow chamber 261 flows through the water outlet device 280 to the water distribution basin 230, forming a third water distribution. Therefore, by adopting the combined design of the water distribution system 200 with the main water inlet pipe 210, the water inlet branch pipe 220, the water distribution unit 240, and the water distribution basin 230, and by adopting the combined design of the water distribution unit 240 with the water inlet flange 241, the water distributor 250, and the anti-support 260, a three-stage water distribution can be formed, realizing three-stage pressure reduction and energy reduction, so as to significantly reduce the water inlet pressure, reduce the damage to the water distribution basin 230 caused by the impact of water on the water distribution basin 230, and effectively extend the service life of the water distribution system 200.
[0030] Specifically, the bottom of the water distribution basin 230 is evenly provided with a number of spray nozzles 231, and the center line of the inverted support 260 coincides with the center axis of the water distribution chamber 251.
[0031] The inverted support 260 includes a rectangular base plate 263 and four side plates 264 that are respectively arranged around the perimeter of the base plate 263; any two adjacent side plates 264 are connected; the base plate 263 and the four side plates 264 form the overflow cavity 261. By adopting the above structure, the manufacturing and formation of the overflow cavity 261 can be facilitated.
[0032] The protruding wall 262 is formed on the base plate 263. Specifically, the protruding wall 262 extends along the width direction of the base plate 263 and is strip-shaped. The protruding wall 262 includes a top wall, a front wall, a rear wall, and a first side wall and a second side wall arranged opposite to each other. The front wall is located between the front ends of the first side wall and the front ends of the second side wall, the rear wall is located between the rear ends of the first side wall and the rear ends of the second side wall, and the top wall is located between the top ends of the first side wall and the top ends of the second side wall. By adopting the above structure, the first side wall and the second side wall of the protruding wall 262 can block and buffer the water flowing into the overflow chamber 261, and facilitate processing.
[0033] The lifting plate device 270 includes a lifting plate 271 that slides and seals against the inner wall of the overflow chamber 261. The lifting plate 271 is driven to rise and fall by a lifting drive component 272. Because the lifting plate 271 seals against the inner wall of the overflow chamber 261, a sealing effect is ensured, preventing water from flowing downwards through the gap between the lifting plate 271 and the inner wall of the overflow chamber 261. Specifically, the lifting plate 271 is provided with a mating hole 277 for the protruding wall 262 to pass through, and the wall of the mating hole 277 slides and seals against the protruding wall 262 to ensure a sealing effect between the wall of the mating hole 277 and the protruding wall 262, preventing water from flowing downwards through the gap between the wall of the mating hole 277 and the protruding wall 262. Based on the base plate 263 and side plate 264 of the anti-support 260, and combined with the lifting plate 271 and the lifting drive component 272, the lifting plate 271 can be driven to rise and fall by the lifting drive component 272, so as to adjust the overflow of water in the overflow chamber 261 and thus adjust the third water distribution volume.
[0034] Specifically, the overflow cavity 261 is rectangular, and the outer contour shape of the lifting plate 271 matches the shape of the overflow cavity 261.
[0035] Preferably, the lifting drive component 272 includes an adjusting sleeve 273 fixed on the lifting plate 271, a first drive motor 274, and an adjusting rod 275 vertically arranged and connected to the output shaft of the first drive motor 274. The adjusting rod 275 is provided with an external thread, and the adjusting sleeve 273 is fitted onto the adjusting rod 275 and is provided with an internal thread that is threadedly connected to the external thread of the adjusting rod 275. In use, the first drive motor 274 drives the adjusting rod 275 to rotate forward, which can drive the adjusting sleeve 273 and the lifting plate 271 to descend. As the water level in the overflow chamber 261 gradually rises, the first drive motor 274 drives the adjusting rod 275 to rotate in the opposite direction, which can drive the adjusting sleeve 273 and the lifting plate 271 to rise. The rising of the lifting plate 271 can gradually push the water upward, causing the water in the overflow chamber 261 to overflow outward, thereby coordinating with the water distribution to the water distribution basin 230, and adjusting the overflow of water in the overflow chamber 261 in the above manner.
[0036] Specifically, a storage box 276 is fixed below the reverse support 260. The body of the first drive motor 274 and the adjusting rod 275 are both located inside the storage box 276. By adopting the above structure, the storage box 276 can protect and waterproof the first drive motor 274. The reverse support 260 is provided with a mounting hole, and the adjusting sleeve 273 passes through the mounting hole. A sealing ring for sealing and slidingly engaging with the adjusting sleeve 273 is fixed in the mounting hole. By adopting the above structure, the sealing performance between the adjusting sleeve 273 and the reverse support 260 can be ensured.
[0037] The upper cross-section of the water distribution cavity 251 is circular, and the lower cross-section is rectangular, to facilitate the formation of a gradually increasing cross-sectional area from the upper to the lower end of the water distribution cavity 251. In this embodiment, the water distributor 250 includes a water distribution shell integrally injection molded from PVC material. The water distribution cavity 251 is formed on the water distribution shell. The upper end of the water distribution shell is circular, and the lower end is rectangular. By adopting the above structure, the manufacture of the water distributor 250 can be facilitated.
[0038] The water outlet device 280 includes a water outlet guide plate 281 disposed between the anti-support 260 and the cavity sidewall of the water distribution chamber 251. The water outlet guide plate 281 has a plurality of water outlet holes 282 arranged at equal intervals along its length. An adjusting plate device 283 is installed below the water outlet guide plate 281. The adjusting plate device 283 includes a water outlet adjusting plate 284 and a transverse moving assembly. The water outlet adjusting plate 284 has holes corresponding to the plurality of water outlet holes 282. A plurality of water outlet grooves 298 are configured to communicate with the corresponding water outlet holes 282, and a plurality of covering parts 285 are configured to cover the corresponding water outlet holes 282, each corresponding to one of the water outlet holes 282. The plurality of water outlet grooves 298 and covering parts 285 are arranged alternately along the length direction of the water outlet guide plate 281. The transverse moving component of the water outlet device 280 is used to drive the water outlet regulating plate 284 of the water outlet device 280 to move along the length direction of the water outlet guide plate 281 of the water outlet device 280. In use, the horizontal movement component drives the water outlet regulating plate 284 to move forward, causing each water outlet 298 to move toward the corresponding water outlet 282. This increases the area of the water outlet 298 facing the corresponding water outlet 282 and decreases the area of the covering part 285 facing the corresponding water outlet 282, thereby increasing the amount of water flowing to the water distribution basin 230. Conversely, the horizontal movement component drives the water outlet regulating plate 284 to move in the opposite direction, causing the area of the water outlet 298 facing the corresponding water outlet 282 to decrease and the area of the covering part 285 facing the corresponding water outlet 282 to increase, thereby decreasing the amount of water flowing to the water distribution basin 230.
[0039] Specifically, the water outlet guide plate 281 is disposed between the side plate 264 of the inverted support 260 and the cavity side wall at the lower end of the water distribution cavity 251. The water outlet guide plate 281 has a downward-facing recessed guide groove 286 that communicates with the water outlet hole 282. The top of the side plate 264 of the inverted support 260 is provided with a notch 267 for water from the overflow cavity 261 to overflow towards the guide groove 286. In use, water from the top of the overflow cavity 261 can overflow towards the guide groove 286 through the notch 267, flow towards the water outlet hole 282 through the guide groove 286, and then flow out towards the water distribution basin 230 through the water outlet groove 298. Specifically, the inner bottom wall of the notch 267 is flush with the inner bottom wall of the guide groove 286.
[0040] The water outlet regulating plate 284 of the water outlet device 280 is movably installed below the water outlet guide plate 281 of the water outlet device 280. The lateral movement assembly includes a rack 287 disposed on the water outlet regulating plate 284, a transmission gear 288 meshing with the rack 287, and a power component 289 for driving the transmission gear 288 to rotate. In use, the power component 289 drives the transmission gear 288 to rotate forward, which in turn drives the rack 287 and the water outlet regulating plate 284 to move forward, causing each water outlet trough 298 to move toward the corresponding water outlet 282, thereby increasing the amount of water flowing to the water distribution basin 230. Conversely, the power component 289 drives the transmission gear 288 to rotate in the opposite direction, which in turn drives the rack 287 and the water outlet regulating plate 284 to move in the opposite direction, causing each water outlet trough 298 to move away from the corresponding water outlet 282, thereby reducing the amount of water flowing to the water distribution basin 230.
[0041] Specifically, the power component 289 is a second drive motor. A receiving box is provided below the water outlet guide plate 281. The body of the second drive motor is fixed inside the receiving box, and the output shaft of the second drive motor extends out of the receiving box. The transmission gear 288 is fixed on the part of the second drive motor's output shaft that extends out of the receiving box.
[0042] As a further preferred embodiment of the present invention, an installation plate is provided below the water outlet guide plate 281, and a sliding guide groove is formed between the water outlet guide plate 281 and the installation plate. One side of the water outlet regulating plate 284 is slidably embedded in the sliding guide groove so that the water outlet regulating plate 284 slides along the sliding guide groove under the drive of the transverse component, and the sliding guide groove can guide the movement of the water outlet regulating plate 284.
[0043] In a preferred embodiment of the present invention, a water outlet device 280 is provided between each side plate 264 of the inverted support 260 and the cavity side wall of the water distribution chamber 251, so that water overflowing from the recesses 267 of each side plate 264 of the inverted support 260 can flow to the water distribution basin 230 through each water outlet device 280 and be sprayed out through the spray nozzles 231 of the water distribution basin 230. Since a water outlet device 280 is provided between each side plate 264 of the inverted support 260 and the cavity side wall of the water distribution chamber 251, the water flow from each water outlet device 280 to each area of the water distribution basin 230 can be made more uniform through the synchronous adjustment of each water outlet device 280, thereby improving the water distribution uniformity of the water distribution basin 230, improving the cooling effect, and protecting the entire system.
[0044] Preferably, a wing 265 is provided between the top ends of any two adjacent side plates 264 of the anti-support 260, and a guiding gap area 266 is formed between the wing 265 at both ends of each side plate 264 to guide water to the notch 267.
[0045] The water distributor 250 is fixedly connected to the water inlet flange 241 via a fixing plate 242. Specifically, the fixing plate 242 is in the shape of a rotating body, and a central hole is provided in the middle of the fixing plate 242. The inner cavity of the water inlet flange 241 is connected to the water distribution chamber 251 of the water distributor 250 through the central hole of the fixing plate 242. The fixing plate 242 includes a circular main body 243, a lower plate 244 extending downward from the circumferential edge of the main body 243, and a bent plate 245 extending outward from the circumferential edge of the lower plate 244. The main body 243 of the fixing plate 242 is fixed between the water inlet flange 241 and the water distributor 250, and the central hole is located on the main body 243. The top of the water distribution basin 230 is provided with a fixing seat 246, and the fixing seat 246 is provided with an embedding groove. The fixing plate 242 is fixed on the fixing seat 246, and the bent plate 245 is embedded in the embedding groove. By adopting the above structure, the installation and positioning of the fixing plate 242 and the fixing seat 246 can be facilitated.
[0046] The inlet flange 241 is integrally injection molded from PVC material and galvanized, saving significant production time and ensuring quality. The upper end of the inlet flange 241 connects to the corresponding inlet branch pipe 220, and the lower end connects to the fixing plate 242. The fixing plate 242 is made of heavily galvanized steel sheet, which increases its strength and serves to fix the distributor 250 and the inlet flange 241 together, bearing the weight and inlet pressure of the inlet branch pipe 220.
[0047] In this embodiment, packing assemblies 150 are provided on both sides of the tower body 110, and air outlets 111 are provided on both opposite sides of the tower body 110 corresponding to the packing assemblies 150. The water distribution system 200 includes two water inlet branch pipes 220 arranged sequentially along the length of the water inlet main pipe 210 and connected to the water inlet main pipe 210, two water distribution units 240 corresponding to the two water inlet branch pipes 220, and two water distribution basins 230 corresponding to the two water distribution units 240. The water inlet flange 241 of the water distribution unit 240 is connected to the corresponding water inlet branch pipe 220. The two water distribution basins 230 are respectively... The guide slots 311 and secondary temperature regulating slots 312 are respectively arranged above the packing assemblies 150 on both sides of the tower body 110. The number of guide slots 311 and secondary temperature regulating slots 312 is set to two. The two guide slots 311 and secondary temperature regulating slots 312 correspond to the packing assemblies 150 on both sides of the tower body 110. The two guide slots 311 and secondary temperature regulating slots 312 are arranged alternately in a circle around the central axis of the adjusting seat 310. When the adjusting seat 310 is in the first position, the two guide slots 311 are respectively directly opposite the packing assemblies 150 on both sides of the tower body 110. When the adjusting seat 310 is in the second position, the two secondary temperature regulating slots 312 are respectively directly opposite the packing assemblies 150 on both sides of the tower body 110.
