Description

Technical Field

[0001] This utility model relates to the field of air-cooled island cooling technology, and in particular to an indoor cooling device for air-cooled islands in summer. Background Technology

[0002] Air-cooled islands are core equipment in thermal power plants that use air as a cooling medium to cool high-temperature steam. They mainly consist of radiator clusters, axial fan matrices, and intelligent control systems. Employing direct or indirect air-cooling technology, they achieve steam condensation through heat exchange between finned tube bundles and air. Compared to traditional wet-cooling systems, they achieve a water saving rate of up to 90%, with a single 1,000 kW unit saving up to 12 million tons of water annually. This system is widely used in the coal-rich but water-scarce regions of Northwest China. It integrates hundreds of high-flow axial fans on a steel frame support platform, and incorporates frequency conversion compensation technology to ensure operational stability in extreme environments such as high altitudes and high temperatures.

[0003] Under high-temperature and high-load operating conditions in summer, the increased ambient temperature leads to a significant decrease in the heat exchange efficiency of the air-cooled island, which in turn affects the unit's operation. Therefore, spray cooling measures are often used to improve cooling performance. However, existing spray cooling systems generally suffer from limited spray coverage area and poor cooling effect, making it difficult to meet the requirements of high-efficiency operation.

The third rack is disposed on the side of the plate body away from the first movable plate. The outer wall of the atomizing nozzle component is provided with a transmission gear. The third rack meshes with the transmission gear so that the first movable plate can drive the atomizing nozzle component to rotate relative to the spray pipe through the plate body, the third rack, and the transmission gear. The first direction and the second direction are perpendicular to each other.

[0022] In one embodiment, there are multiple atomizing nozzle components, which are spaced apart along a second direction. Each atomizing nozzle component has a chain wheel on its outer wall, and the cooling mechanism also includes a chain. Each chain wheel meshes with the chain.

[0023] In one embodiment, the atomizing nozzle component includes a sealing connector and an atomizing nozzle.

[0025] And / or,

[0026] There are multiple spray components, which are spaced apart along the first direction. The number of third racks and transmission gears is the same as the number of spray components and they are arranged in a one-to-one correspondence.

[0027] In one embodiment, the number of tube bundle mechanisms is at least two, and the number of cooling mechanisms is the same as the number of tube bundle mechanisms and is arranged in a one-to-one correspondence. The at least two tube bundle mechanisms include a first tube bundle mechanism and a second tube bundle mechanism. Both the first tube bundle mechanism and the second tube bundle mechanism are connected to the bottom of the steam distribution pipe, and the first tube bundle mechanism and the second tube bundle mechanism are arranged symmetrically with respect to the steam distribution pipe.

The air-cooled island summer indoor cooling device also includes an auxiliary mechanism, which includes a fixed plate and at least one fan. Each cooling mechanism is connected to the fixed plate, and at least one fan is connected to the fixed plate.

[0028] In this embodiment of the invention, the air-cooled island indoor cooling device for summer includes a steam distribution pipe, a tube bundle mechanism, and a cooling mechanism. The tube bundle mechanism is connected to the steam distribution pipe and is used to cool the high-temperature steam from the steam distribution pipe. The cooling mechanism includes a fixed frame, a drive assembly, a connecting plate, a transmission assembly, and a spray assembly. The spray assembly consists of a spray pipe and multiple rotatably mounted atomizing nozzle components, with the nozzles of the atomizing nozzle components facing the tube bundle mechanism to achieve directional spray cooling. The steam distribution pipe, tube bundle mechanism, and drive assembly are all fixedly connected to the fixed frame to ensure the overall structure is stable and reliable. The spray pipe is connected to the connecting plate, and the connecting plate slides along the fixed frame in a first direction, allowing the connecting plate to drive the spray pipe to reciprocate along the first direction, expanding the spray coverage area. The transmission assembly includes a first movable plate and a second movable plate connected to each other. The first movable plate also slides along the fixed frame, while the second movable plate is drivenly connected to the atomizing nozzle components, allowing the linear motion of the first movable plate to be converted into the rotational motion of the atomizing nozzle components through the second movable plate. Both the connecting plate and the first movable plate are connected to the drive assembly for transmission. The drive assembly can synchronously drive both plates to move relative to the fixed frame along a first direction. Furthermore, the drive assembly can also drive the connecting plate to move relative to the first movable plate in the same or opposite direction, ensuring that the connecting plate and the first movable plate are not stationary relative to each other. This allows the connecting plate to move relative to the first movable plate, thereby driving the atomizing nozzle component to rotate relative to the spray pipe while the spray pipe reciprocates. Compared to traditional fixed spray systems, this solution achieves dynamic expansion of the spray area without significantly increasing the number of atomizing nozzle components and spray pipes. This significantly improves the overall spray area and cooling effect, enhances the wetting uniformity and evaporative cooling efficiency of the air-cooled island tube bundle surface, and strengthens the overall heat exchange performance of the system. Simultaneously, because it eliminates the need to increase nozzle density or complex piping to compensate for insufficient coverage, it effectively reduces material usage, system complexity, and subsequent maintenance costs. This achieves dual savings in construction and operation costs while improving cooling efficiency, fundamentally overcoming the technical bottlenecks of limited coverage, poor uniformity, and high cost of existing spray cooling technologies. This embodiment of the invention employs a single drive component to synchronously drive the connecting plate and the first movable plate in opposite directions, achieving the lateral reciprocating movement of the spray pipe and the synchronous rotation of the atomizing nozzle component. The two work together to effectively expand the spray coverage area, improve the overall spray area and cooling uniformity, and enhance the cooling effect on the surface of the tube bundle structure without significantly increasing the number of atomizing nozzle components and spray pipes. At the same time, it avoids the system complexity and high cost problems caused by increasing the nozzle density in traditional solutions, significantly reduces material usage and maintenance costs, and improves the energy efficiency and economy of the air-cooled island cooling system.

[0043] Air-cooled islands are core equipment in thermal power plants that use air as a cooling medium to cool high-temperature steam. They mainly consist of radiator clusters, axial fan matrices, and intelligent control systems. Employing direct or indirect air-cooling technology, they achieve steam condensation through heat exchange between finned tube bundles and air. Compared to traditional wet-cooling systems, they achieve a water saving rate of up to 90%, with a single 1,000 kW unit saving up to 12 million tons of water annually. This system is widely used in the coal-rich but water-scarce regions of Northwest China. It integrates hundreds of high-flow axial fans on a steel frame support platform, and incorporates frequency conversion compensation technology to ensure operational stability in extreme environments such as high altitudes and high temperatures.

[0044] Under high-temperature and high-load operating conditions in summer, the increased ambient temperature leads to a significant decrease in the heat exchange efficiency of the air-cooled island, which in turn affects the unit's operation. Therefore, spray cooling measures are often used to improve cooling performance. However, existing spray cooling systems generally suffer from limited spray coverage area and poor cooling effect, making it difficult to meet the requirements of high-efficiency operation.

[0045] After careful study, the applicant discovered that current air-cooled island spray cooling systems mostly employ fixed atomizing nozzles and spray pipes, with the nozzle positions and spray directions remaining constant. This static spraying method results in a fixed water mist spraying area, limiting the coverage and failing to achieve uniform wetting and sufficient evaporative cooling of the high-temperature tube bundle surface. To compensate for insufficient coverage, existing solutions often increase the number of nozzles and densify the spray pipe arrangement. While this can expand the coverage area to some extent, it directly leads to increased system complexity, increased material consumption, and increased maintenance difficulty. Therefore, the fundamental flaw of existing solutions lies in the lack of a technical means to achieve large-area, uniform spraying without relying on a large number of additional nozzles.

[0046] The main purpose of this invention is to propose an air-cooled island indoor cooling device for summer to solve the problem of how to expand the spray coverage area to improve the cooling effect.

[0047] Please see Figures 1 to 4 In one embodiment of this utility model, the air-cooled island indoor cooling device 100 in summer includes a steam distribution pipe 1, a tube bundle mechanism, and a cooling mechanism 3. The tube bundle mechanism is connected to the steam distribution pipe 1. The cooling mechanism 3 includes a fixed frame 31, a drive assembly 32, a connecting plate, a transmission assembly 35, and a spray assembly 36. The spray assembly 36 includes a spray pipe 361 and an atomizing nozzle component 362. The steam distribution pipe 1, the tube bundle mechanism, and the drive assembly 32 are all connected to the fixed frame 31. The atomizing nozzle component 362 is rotatably mounted on the spray pipe 361, and the nozzle of the atomizing nozzle component 362 faces the tube bundle mechanism. The spray pipe 361 is connected to the connecting plate, and the connecting plate and the fixed frame 31 slide in a first direction so that the connecting plate can drive the spray pipe. 361 moves relative to the fixed frame 31 along a first direction; the transmission assembly 35 includes a first movable plate 351 and a second movable plate 352, the first movable plate 351 and the second movable plate 352 are connected, the second movable plate 352 is drivenly connected to the atomizing nozzle component 362, the first movable plate 351 and the fixed frame 31 are slidably engaged along the first direction, so that the first movable plate 351 can drive the atomizing nozzle component 362 to rotate relative to the spray pipe 361 through the second movable plate 352; the connecting plate and the first movable plate 351 are both drivenly connected to the driving assembly 32, the driving assembly 32 can drive the connecting plate and the first movable plate 351 to move relative to the fixed frame 31, and the driving assembly 32 can also drive the connecting plate to move relative to the first movable plate 351.

[0048] In the embodiments of this utility model, such as Figure 1As shown, the first direction is left-right. The air-cooled island indoor cooling device 100 includes a steam distribution pipe 1, a tube bundle mechanism, and a cooling mechanism 3. The tube bundle mechanism is connected to the steam distribution pipe 1 and is used to cool the high-temperature steam from the steam distribution pipe 1. The cooling mechanism 3 includes a fixed frame 31, a drive assembly 32, a connecting plate, a transmission assembly 35, and a spray assembly 36. The spray assembly 36 consists of a spray pipe 361 and multiple rotatably mounted atomizing nozzle components 362, with the nozzles of the atomizing nozzle components 362 facing the tube bundle mechanism to achieve directional spray cooling. The steam distribution pipe 1, the tube bundle mechanism, and the drive assembly 32 are all fixedly connected to the fixed frame 31 to ensure the overall structure is stable and reliable. The spray pipe 361 is connected to the connecting plate, and the connecting plate slides in the first direction with the fixed frame 31, allowing the connecting plate to drive the spray pipe 361 to reciprocate along the first direction, expanding the spray coverage area. The transmission assembly 35 includes a first movable plate 351 and a second movable plate 352 connected to each other. The first movable plate 351 is also slidably engaged with the fixed frame 31, while the second movable plate 352 is drivenly connected to the atomizing nozzle component 362, so that the linear motion of the first movable plate 351 can be converted into the rotational motion of the atomizing nozzle component 362 through the second movable plate 352. Both the connecting plate and the first movable plate 351 are drivenly connected to the drive assembly 32. The drive assembly 32 can synchronously drive both of them to move relative to the fixed frame 31 in a first direction. The drive assembly 32 can also drive the connecting plate to move relative to the first movable plate 351 in the same or opposite direction, so that the connecting plate and the first movable plate 351 are not stationary relative to each other. That is, the connecting plate can move relative to the first movable plate 351, thereby driving the atomizing nozzle component 362 to rotate relative to the spray pipe 361 while the spray pipe 361 is reciprocating. Compared to traditional fixed spray systems, this solution achieves dynamic expansion of the spray area without significantly increasing the number of atomizing nozzle components 362 and spray pipes 361. This significantly increases the overall spray area and cooling effect, substantially improves the wetting uniformity and evaporative cooling efficiency of the air-cooled island tube bundle surface, and enhances the overall heat exchange performance of the system. Simultaneously, because it eliminates the need to increase nozzle density or complex piping to compensate for insufficient coverage, it effectively reduces material usage, system complexity, and subsequent maintenance costs. Thus, while improving cooling efficiency, it achieves dual savings in construction and operation costs, fundamentally overcoming the technical bottlenecks of existing spray cooling technologies, such as limited coverage, poor uniformity, and high costs.

[0049] The technical solution of this utility model adopts a single drive component 32 to synchronously drive the connecting plate and the first movable plate 351 to move in opposite directions, so as to realize the lateral reciprocating movement of the spray pipe 361 and the synchronous rotation of the atomizing nozzle component 362. The two work together to effectively expand the spray coverage area, improve the overall spray area and cooling uniformity, and enhance the cooling effect on the surface of the tube bundle mechanism without significantly increasing the number of atomizing nozzle components 362 and spray pipes 361. At the same time, it avoids the system complexity and high cost caused by increasing the nozzle density of traditional solutions, significantly reduces the amount of materials used and maintenance costs, and improves the energy efficiency and economy of the air-cooled island cooling system.

[0050] Please see Figure 3 and Figure 5In one embodiment, the drive assembly 32 includes a rotating wheel 321, a first rack 322, and a second rack 323. The rotating wheel 321 is rotatably mounted on a fixed frame 31. A first sector rack 3211 and a second sector rack 3212 are provided on the outer wall of the rotating wheel 321. The first sector rack 3211 and the second sector rack 3212 are spaced apart circumferentially along the rotating wheel 321. The rotating wheel 321 is located between a connecting plate and a first movable plate 351. A first rack 322 is provided on the side of the connecting plate facing the rotating wheel 321. The first rack 322 can mesh with either the first sector rack 3211 or the second sector rack 3212. The rotating wheel 321 can drive the first rack 322 and the connecting plate to move relative to the fixed frame 31 in a first direction via the first sector rack 3211 or the second sector rack 3212. A second rack 323 is provided on the side of the first movable plate 351 facing the rotating wheel 321. The second rack 323 can mesh with either the first sector rack 3211 or the second sector rack 3212. The second sector rack 3212 or the first sector rack 3211 engages, and the rotating wheel 321 can drive the second rack 323 and the first movable plate 351 to move relative to the fixed frame 31 in the first direction through the second sector rack 3212 or the first sector rack 3211, and the moving directions of the connecting plate and the first movable plate 351 are opposite. Specifically, since the first sector rack 3211 and the second sector rack 3212 are circumferentially spaced on the rotating wheel 321 and are not connected to each other, they engage with the corresponding racks in sequence and transmit power during the rotation of the rotating wheel 321. That is, when the first sector rack 3211 engages with the first rack 322, the second sector rack 3212 engages with the second rack 323, or when the first sector rack 3211 engages with the second rack 323, the second sector rack 3212 engages with the first rack 322, thereby realizing the synchronous movement of the connecting plate and the first movable plate 351 in opposite directions in the first direction. This structure achieves coordinated drive of two moving parts through a single rotating wheel 321, eliminating the need for additional drive sources or complex linkage mechanisms. The transmission path is simple, the operation is reliable, and the system's integration and operational stability are improved. Through a reasonable tooth profile layout, this design achieves precise control of motion timing, combining structural simplicity with functional reliability, providing an effective drive solution for the reciprocating sliding of the spray pipe 361 and the coordinated rotation of the atomizing nozzle component 362.

[0051] According to one embodiment of the present invention, the drive assembly 32 can be a bidirectional hydraulic rod or a double lead screw driven by a motor, etc., which can realize the output of linear motion on both sides. The two output ends of the drive assembly 32 are respectively connected to the connecting plate and the first movable plate 351, thereby realizing the synchronous movement of the connecting plate and the first movable plate 351 in opposite directions along the first direction.

[0052] According to another embodiment of the present invention, the drive assembly 32 includes a rotating wheel 321, a first rack 322, and a second rack 323. The rotating wheel 321 is rotatably mounted on the fixed frame 31. The outer wall of the rotating wheel 321 is provided with a first sector-shaped rack 3211 and a second sector-shaped rack 3212. The first sector-shaped rack 3211 and the second sector-shaped rack 3212 have the same starting angle but different wrap angles. The rotating wheel 321 is located between the connecting plate and the first movable plate 351. The first rack 321 is provided on the side of the connecting plate facing the rotating wheel 321. 22. The first rack 322 meshes with the first sector rack 3211. The rotating wheel 321 can drive the connecting plate to move relative to the fixed frame 31 in the first direction through the first sector rack 3211 and the first rack 322. The first movable plate 351 is provided with a second rack 323 on the side facing the rotating wheel 321. The second rack 323 meshes with the second sector rack 3212. The rotating wheel 321 can drive the first movable plate 351 to move relative to the fixed frame 31 in the first direction through the second sector rack 3212 and the second rack 323. Because the wrap angles of the first sector rack 3211 and the second sector rack 3212 are different, the meshing ranges between the two and the corresponding racks are different. Therefore, during the rotation of the wheel 321, although the connecting plate and the first movable plate 351 move in the same direction, the moving distances are inconsistent, forming a phased or full-range relative displacement. The two cannot remain relatively stationary, thus realizing the stroke difference between the connecting plate and the first movable plate in the same direction of movement, and satisfying the coordinated driving requirements of the spray pipe and the atomizing nozzle components.

[0053] Please see Figure 2 , Figure 3 and Figure 6In one embodiment, the fixed frame 31 includes a frame 311 and a guide reset assembly 312. The steam distribution pipe 1 and the pipe bundle mechanism are both connected to the frame 311. The rotating wheel 321 is rotatably mounted on the frame 311. The frame 311 is provided with a receiving cavity 31111 for accommodating the spray pipe 361. The connecting plate and the first movable plate 351 are both slidably engaged with the frame 311 along a first direction. The two ends of the connecting plate, which are opposite each other along the first direction, are the first end 331 and the second end 332, respectively. The connecting plate has an initial position (not shown) and a working position (not shown). The connecting plate can initially... The rotating wheel 321 reciprocates between the initial position and the working position, and can drive the connecting plate from the initial position to the working position through the first sector rack 3211 or the second sector rack 3212; the guide reset assembly 312 includes a first guide reset member 3121, which includes a first guide rod 31211 and a first elastic reset member 31212. The first guide rod 31211 is connected to the frame 311, and a first sliding hole (not shown) is provided at the first end 331. The first sliding hole is slidably engaged with the first guide rod 31211, and the first elastic reset member 31212 is sleeved on the first guide rod 31211. The outer wall of rod 31211, the first sector rack 3211 and the second sector rack 3212 are both separated from the first rack 322, the first elastic reset member 31212 can drive the connecting plate to move from the working position to the initial position; and / or, the guide reset assembly 312 includes a second guide reset member 3122, the second guide reset member 3122 includes a second guide rod (not shown) and a second elastic reset member (not shown), the second guide rod is connected to the frame 311, the second end 332 is provided with a second sliding hole (not shown), the second sliding hole is slidably engaged with the second guide rod, and the second elastic reset member is sleeved. Located on the outer wall of the second guide rod, the first sector rack 3211 and the second sector rack 3212 are both separated from the first rack 322. The second elastic reset member can drive the connecting plate to move from the working position to the initial position. Specifically, the steam distribution pipe 1 and the pipe bundle mechanism are both connected to the frame 311 to form a stable overall structure. The rotating wheel 321 is rotatably mounted on the frame 311 and serves as the core transmission fulcrum for driving the motion. The frame 311 is provided with a receiving cavity 31111 for accommodating the spray pipe 361, which not only provides spatial protection for the spray pipe 361 but also provides limiting guidance for its reciprocating movement.The connecting plate has two ends, 331 and 332, arranged opposite each other along the first direction. Its movement has a clear initial position and working position, and it can move back and forth between the two. The rotating wheel 321 meshes with the first rack 322 on the connecting plate through the first sector rack 3211 or the second sector rack 3212. When the rotating wheel 321 rotates under the drive of the driving member 324, the first sector rack 3211 or the second sector rack 3212 is in a meshing state with the first rack 322 only within a specific angle range of its rotation, thereby pushing the connecting plate from the initial position to the working position and completing the push stroke action of the spray system. When the rotating wheel 321 continues to rotate, after the first sector rack 3211 and the second sector rack 3212 disengage from the meshing area of ​​the first rack 322, the active driving force disappears. At this time, the connecting plate moves in the opposite direction under the action of the elastic reset member, returning from the working position to the initial position, realizing the return stroke action. Furthermore, when the connecting plate drives the spray pipe 361 to reset as a whole under the action of the elastic reset component, the transmission connection between the spray pipe 361 and the second movable plate 352 drives the second movable plate 352 and the first movable plate 351 to return to their initial positions synchronously, realizing the linkage reset of the first movable plate 351. No additional reset components are required, resulting in a compact structure and coordinated movement. The guide reset assembly 312 includes a first guide reset component 3121 and / or a second guide reset component 3122, and the configuration can be flexibly selected according to the actual structural layout and load requirements. In this embodiment, the first guide reset component 3121 and the second guide reset component 3122 are set simultaneously to achieve symmetrical support and synchronous reset at both ends of the connecting plate, further improving the linearity, stability, and anti-eccentric load capacity of the movement process. This structure, through the synergistic design of intermittent transmission of the fan-shaped rack and pinion and double-end elastic guide reset, realizes reliable driving and smooth reset of the reciprocating motion of the connecting plate, taking into account both transmission efficiency and structural stability, and providing an efficient, simple, and easy-to-maintain support solution for the periodic reciprocating operation of the spray assembly 36. In this embodiment, the guide rods in both guide reset components slide in conjunction with the corresponding sliding holes on the connecting plates, thereby achieving precise guidance. In this embodiment, both the first elastic reset component 31212 and the second elastic reset component can be common elastic elements such as helical compression springs, helical tension springs, or rubber elastomers found in existing structures; this embodiment does not impose any limitations on this.

[0054] Please see Figure 2 and Figure 3 In one embodiment, the number of connecting plates is at least two, including a first connecting plate 33 and a second connecting plate 34. The first connecting plate 33 and the second connecting plate 34 are respectively connected to the two ends of the spray pipe 361 that are arranged opposite to each other along the second direction. The number of guide reset components 312 is the same as the number of connecting plates and they are arranged in a one-to-one correspondence. A first rack 322 is provided on the first connecting plate 33 or the second connecting plate 34, and the first direction and the second direction are perpendicular to each other. Specifically, as shown in the figure... Figure 1As shown, the second direction is the vertical direction. The first connecting plate 33 and the second connecting plate 34 are respectively connected to the two ends of the spray pipe 361 that are opposite to each other along the second direction, so that the spray pipe 361 is supported at both ends in the axial direction, which significantly improves its structural stability and smoothness of movement. The number of guide and reset components 312 corresponds one-to-one with the connecting plates, providing independent guiding and reset functions for each connecting plate, ensuring straightness and reliability during movement. Among them, the first rack 322 is set on the first connecting plate 33 or the second connecting plate 34, and meshes with the first sector rack 3211 or the second sector rack 3212 on the rotating wheel 321 to transmit driving force. This design means that the rotating wheel 321 can be selectively installed on either end of the spray pipe 361 (i.e., the side of the first connecting plate 33 or the side of the second connecting plate 34), and the reciprocating drive of the entire spray pipe 361 can be achieved by only one side of the connecting plate. This single-sided drive and double-end support structure allows for highly flexible arrangement of the drive assembly 32. Depending on the installation space, pipeline routing, or maintenance needs, the upper or lower end can be flexibly selected as the drive end without changing the overall structural design, greatly improving the adaptability and ease of installation of the device.

[0055] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5In one embodiment, a first connecting plate 33 is disposed at the end of the spray pipe 361 away from the steam distribution pipe 1. A first rack 322 is disposed on the first connecting plate 33. The drive assembly 32 further includes a drive member 324, which is connected to the side of the frame 311 away from the pipe bundle mechanism. The output end of the drive member 324 is connected to the rotating wheel 321 for transmission, so that the drive member 324 can drive the rotating wheel 321 to rotate relative to the fixed frame 31. And / or, the frame 311 includes a frame body 3111, a first support block 3112 and a second support block 3113. The steam distribution pipe 1 and the guide reset assembly 312 are both connected to the frame body 3111. The rotating wheel 321 is rotatably mounted on the frame body 3111. The frame body 3111 is provided with a receiving cavity 31111. The connecting plate and the first movable plate 351 are both slidably engaged with the frame body 3111 along the first direction. The first support block 3112 and the second support block 3113 are spaced apart on the frame body 3111 along the second direction. The tube bundle mechanism includes tube bundles 21. The first support block 3112 and the second support block 3113 are both connected to the tube bundles 21. There are multiple tube bundles 21, which are spaced apart along the first direction. The number of the first support blocks 3112 and the second support blocks 3113 is the same as the number of tube bundles 21 and they are arranged in a one-to-one correspondence. Specifically, the first connecting plate 33 is provided at the end of the spray pipe 361 away from the steam distribution pipe 1, that is, at the lower end of the spray pipe 361. This arrangement positions the drive assembly 32 below or at the bottom of the entire cooling mechanism 3, away from the high-temperature and high-humidity steam distribution pipe 1 and tube bundle mechanism above. This not only effectively avoids the thermal radiation impact of the high-temperature environment on the drive components but also reduces the risk of water mist condensation, scale buildup, or corrosion, thus improving the reliability of the system operation. More importantly, placing the drive assembly 32 at the lower end significantly improves the convenience of installation, commissioning, and subsequent maintenance, conforms to ergonomics and on-site operating habits, and facilitates rapid assembly and troubleshooting. By setting the drive component 324, the spraying action can be automated and periodically controlled, improving the uniformity and controllability of the cooling process. The overall structure is compact, the transmission is precise, and the response is reliable. In addition, the frame 311 includes a frame body 3111, a first support block 3112, and a second support block 3113. The first support block 3112 and the second support block 3113 are used to support multiple tube bundles 21 in the tube bundle mechanism. The multiple tube bundles 21 are arranged at intervals along a first direction to form a highly efficient heat exchange array. The number of first support blocks 3112 and second support blocks 3113 corresponds to the number of tube bundles 21, ensuring that each tube bundle 21 is stably supported at both ends. This effectively improves the rigidity and thermal deformation adaptability of the overall structure, preventing misalignment or stress concentration caused by thermal expansion and contraction. In this embodiment, the drive unit 324 can be a stepper motor, servo motor, geared motor, or pneumatic motor, or other power devices that can provide stable rotational output, thereby achieving precise start and stop and rhythm adjustment of reciprocating motion to meet the spraying requirements under different working conditions.In addition, in this embodiment, the sliding engagement between the first movable plate 351 and the frame body 3111 along the first direction can be achieved through various specific structures to ensure the smoothness of its reciprocating motion and the guiding accuracy. For example, a slide rail can be provided on the frame body 3111, and a matching slide groove can be provided on the first movable plate 351. The two form a sliding pair, allowing the first movable plate 351 to slide along the extension direction of the slide rail (i.e., the first direction). Alternatively, a guide rod can be fixed on the frame body 3111, and a sliding hole can be provided on the first movable plate 351. The fixed guide rod passes through the sliding hole, and linear guidance is achieved through the cooperation between the fixed guide rod and the sliding hole. This embodiment does not limit this aspect.

[0056] According to one embodiment of the present invention, the first connecting plate 33 is disposed at one end of the spray pipe 361 near the steam distribution pipe 1, that is, at the upper end of the spray pipe 361. This arrangement causes the drive assembly 32 to be located in the upper region of the entire cooling mechanism 3.

[0057] Please see Figure 2 and Figure 7In one embodiment, the second movable plate 352 includes a plate body 3521, a third rack 3522, and a transmission gear 3523. The plate body 3521 is disposed on the side of the first movable plate 351 near the tube bundle mechanism and extends along the second direction toward the side near the spray pipe 361. The third rack 3522 is disposed on the side of the plate body 3521 away from the first movable plate 351. The transmission gear 3523 is disposed on the outer wall of the atomizing nozzle component 362. The third rack 3522 meshes with the transmission gear 3523 so that the first movable plate 351 can be driven to atomize by the plate body 3521, the third rack 3522, and the transmission gear 3523. The nozzle component 362 rotates relative to the spray pipe 361, and is arranged perpendicularly in the first direction and the second direction. Specifically, in this embodiment, the first movable plate 351 has an L-shaped structure. One end of the plate is a horizontal part connected to the second rack 323 and slidably mounted on the frame 311. The other end extends along the second direction toward the side close to the spray pipe 361 to form a vertical part. The vertical part and the plate body 3521 are arranged relative to the horizontal part and together enclose to form a U-shaped groove structure. The U-shaped groove can prevent the first sector rack 3211 or the second sector rack 3212 from axially separating from the first rack 322 on the connecting plate due to vibration or off-center load during the driving process of the rotating wheel 321, thus ensuring stable and reliable transmission. A third rack 3522 is provided on the plate body 3521, and a transmission gear 3523 is provided on the outer wall of the atomizing nozzle component 362. The third rack 3522 meshes with the transmission gear 3523. When the first movable plate 351 moves along the first direction under the push of the second sector rack 3212, the plate body 3521 drives the third rack 3522 to move, which in turn drives the transmission gear 3523 to rotate, thereby driving the atomizing nozzle component 362 to rotate relative to the spray pipe 361, realizing the dynamic rotation of the nozzle angle to expand the spray coverage area. When the connecting plate drives the spray pipe 361 to reset as a whole under the action of the elastic reset component, the transmission gear 3523 on the spray pipe 361 moves accordingly. Through meshing with the third rack 3522, it drives the plate body 3521 and the first movable plate 351 rigidly connected to it to return to the initial position synchronously, realizing the linkage reset of the first movable plate 351. No additional reset element is required, the structure is compact and the movement is coordinated. The transmission layout is reasonable and the space utilization rate is high. The overall structure ensures the coordinated operation of the reciprocating movement of the spray pipe 361 and the rotation of the atomizing nozzle component 362, while improving the stability, reliability and integration of the system.

[0058] Please see Figure 2 and Figure 4In one embodiment, there are multiple atomizing nozzle components 362, which are spaced apart along a second direction. Each atomizing nozzle component 362 has a sprocket 37 on its outer wall. The cooling mechanism 3 also includes a chain 38, and each sprocket 37 meshes with the chain 38. Specifically, the multiple atomizing nozzle components 362 are spaced apart on the spray pipe 361 along the second direction to cover the entire heat exchange area of ​​the tube bundle mechanism in the axial direction, ensuring uniform spraying. The chain 38 meshes synchronously with the sprockets 37 on all atomizing nozzle components 362, forming a linkage transmission structure. When any atomizing nozzle component 362 rotates under the drive of the transmission gear 3523, the sprocket 37 on its outer wall rotates accordingly, transmitting the motion to the remaining sprockets 37 via the chain 38, thereby driving all atomizing nozzle components 362 to rotate synchronously, achieving uniform adjustment of the nozzle angles of the multiple atomizing nozzle components 362. The chain drive 38 ensures the consistency of rotation of each atomizing nozzle component 362, avoiding problems such as asynchronous rotation or uneven coverage caused by single-point drive, and significantly improving the controllability of the spray range and the uniformity of cooling. At the same time, the meshing transmission between the chain 38 and the chain wheel 37 has the advantages of strong load-bearing capacity, stable operation, and resistance to environmental interference, and is suitable for the high temperature and high humidity working environment of the air-cooled island, effectively ensuring the long-term reliable operation of the spray system.

[0059] Please see Figure 4 and Figure 7In one embodiment, the atomizing nozzle component 362 includes a sealing connector 3621 and an atomizing nozzle 3622. The sealing connector 3621 is rotatably mounted on the spray pipe 361, and the atomizing nozzle 3622 is connected to the sealing connector 3621. The nozzle of the atomizing nozzle 3622 faces the tube bundle mechanism. Each sealing connector 3621 has a chain wheel 37 on its outer wall. The sealing connector 3621 located at the end of the spray pipe 361 away from the steam distribution pipe 1 has a transmission gear 3523 on its outer wall. Specifically, the sealing connector 3621 is rotatably mounted on the spray pipe 361 to prevent leakage of the spray medium. The atomizing nozzle 3622 is connected to the sealing connector 3621 and rotates synchronously with it. The nozzle faces the tube bundle mechanism to ensure that the water mist is accurately sprayed onto the surface of the high-temperature tube bundle 21, thereby achieving efficient evaporative cooling. A transmission gear 3523 is installed on the outer wall of the sealing connection seat 3621 located at the end of the spray pipe 361 away from the steam distribution pipe 1. This position is at the lower end of the system, away from the high-temperature steam area, with a lower ambient temperature and open space, facilitating the arrangement and maintenance of transmission components. By placing the transmission gear 3523 here, the drive component 32 can act on this end through the third rack 3522, realizing direct drive of the atomizing nozzle component 362. This not only avoids the thermal impact of high temperature on the transmission mechanism, but also improves operational reliability and ease of installation and maintenance. This structure combines single-point drive at the lower end with synchronous transmission of the chain 38, ensuring reliable sealing and flexible rotation while realizing the linkage rotation of multiple atomizing nozzle components 362, effectively avoiding spray blind spots and improving the overall cooling efficiency and operational stability of the system.

[0060] Please see Figure 3 , Figure 4 and Figure 7In one embodiment, the atomizing nozzle 3622 includes a first atomizing nozzle 36221 and at least one second atomizing nozzle 36222. Both the first atomizing nozzle 36221 and the at least one second atomizing nozzle 36222 are connected to the sealing connector 3621. The tube bundle mechanism is arranged parallel to the cooling mechanism 3. The first atomizing nozzle 36221 is perpendicular to the tube bundle mechanism. An angle exists between the second atomizing nozzle 36222 and the first atomizing nozzle 36221. The nozzles of both the first atomizing nozzle 36221 and the second atomizing nozzle 36222 face the tube bundle mechanism. And / or, the number of spray components 36 is multiple, and the multiple spray components 36 are spaced apart along a first direction. The third rack 352... The number of transmission gears 3523 and the number of spray components 36 are consistent and correspond one-to-one. Specifically, the first atomizing nozzle 36221 and the second atomizing nozzle 36222 are both connected to the sealing connection seat 3621 and rotate synchronously. The tube bundle mechanism and the cooling mechanism 3 are arranged in parallel. The spray direction of the first atomizing nozzle 36221 is perpendicular to the surface of the tube bundle mechanism to achieve positive and efficient wetting and cooling. The second atomizing nozzle 36222 is inclined relative to the first atomizing nozzle 36221. There is a preset angle between the two to form a multi-angle staggered spray layout, which makes the water mist coverage wider and the penetration stronger, effectively reducing spray dead angles and improving the cooling uniformity of the dense tube bundle 21 area. The number of second atomizing nozzles 36222 can be flexibly configured according to actual cooling requirements. In this embodiment, there are two second atomizing nozzles 36222, respectively arranged on both sides of the first atomizing nozzle 36221, forming a main-side nozzle layout. This allows the water mist to diffuse from the center to both sides, covering a wider heat exchange area, further optimizing the spray distribution and improving cooling efficiency. Furthermore, there are multiple spray components 36, arranged at intervals along the first direction to correspond to the multiple tube bundles 21 arranged along the first direction, enhancing the targeted and comprehensive nature of the overall cooling. The number of third racks 3522 and transmission gears 3523 corresponds one-to-one with the number of spray components 36, meaning each spray component 36 is equipped with an independent transmission unit, enabling the atomizing nozzle components 362 of each spray component 36 to rotate synchronously, ensuring coordinated action across multiple spray areas and improving the overall stability and control accuracy of the system. This structure, through the multi-angle nozzle design and the coordinated arrangement of multiple spray components 36, significantly improves the breadth, depth, and uniformity of the spray coverage, effectively enhancing the cooling effect of the air-cooled island.

[0061] In this embodiment, to achieve comprehensive axial coverage and uniform cooling of the tube bundle mechanism, multiple tube bundles 21 are equidistantly distributed along a first direction, forming a regular heat exchange array. Multiple atomizing nozzle components 362 are equidistantly distributed along a second direction on the spray pipe 361, where the second direction is the axial direction of the spray pipe 361. The nozzle components are evenly arranged along the axial direction of the spray pipe 361, ensuring that the spray range covers the entire axial heat exchange area of ​​the tube bundle mechanism, guaranteeing continuous and blind-spot-free water mist distribution along the entire length, significantly improving wetting uniformity and cooling consistency. Multiple spray components 36 are equidistantly distributed along the first direction, corresponding to the transverse arrangement of the tube bundles 21, further enhancing the spatial coordination of the spraying action. This equidistant and uniformly distributed structural design ensures a high degree of matching between the layout of the atomizing nozzle components 362 and the geometric features of the tube bundles 21, resulting in complete spray coverage. This not only effectively avoids localized dry spots or overheating but also improves the modularity and operational stability of the system, providing a reliable guarantee for achieving efficient and uniform cooling of the air-cooled island under high-temperature conditions.

[0062] Please see Figure 1In one embodiment, the number of tube bundle mechanisms is at least two, and the number of cooling mechanisms 3 is the same as the number of tube bundle mechanisms and is arranged in a one-to-one correspondence. The at least two tube bundle mechanisms include a first tube bundle mechanism 2 and a second tube bundle mechanism 4. The first tube bundle mechanism 2 and the second tube bundle mechanism 4 are both connected to the bottom of the steam distribution pipe 1, and the first tube bundle mechanism 2 and the second tube bundle mechanism 4 are symmetrically arranged relative to the steam distribution pipe 1. The cooling mechanism 3 is located between the first tube bundle mechanism 2 and the second tube bundle mechanism 4. The air-cooled island summer indoor cooling device 100 also includes an auxiliary mechanism 5. The auxiliary mechanism 5 includes a fixed plate 51 and at least one fan 52. Each cooling mechanism 3 is connected to the fixed plate 51, and at least one fan 52 is connected to the fixed plate 51. Specifically, in this embodiment, the number of tube bundle mechanisms is two, namely the first tube bundle mechanism 2 and the second tube bundle mechanism 4. Both are connected to the bottom of the steam distribution pipe 1 and are symmetrically arranged relative to the steam distribution pipe 1 to form a balanced heat exchange structure, which is conducive to uniform steam distribution and smooth condensate return, while improving the structural stability and heat load symmetry of the system. An installation space is formed between the first tube bundle mechanism 2 and the second tube bundle mechanism 4. The number of cooling mechanisms 3 corresponds one-to-one with the tube bundle mechanism, and all cooling mechanisms 3 are located within the installation space, resulting in a compact structure and high space utilization. The fan 52 is integrated with each cooling mechanism 3 via a fixing plate 51, allowing the airflow generated by a single fan 52 to simultaneously cover the spray areas of the first tube bundle mechanism 2 and the second tube bundle mechanism 4, achieving dual-purpose operation and improving equipment integration and operational efficiency. The main function of the fan 52 is to generate directional airflow during spraying, reducing the air retention effect on the surface of the tube bundle 21, helping atomized water droplets overcome airflow resistance, and more effectively adhere to and evenly distribute on the surface of the tube bundle 21, preventing water mist from drifting or leaving areas unwetted, thereby improving wetting coverage and subsequent evaporative cooling efficiency. This layout, through the symmetrical arrangement of the tube bundle mechanism, the symmetrical arrangement of the cooling mechanism 3, and the centrally shared design of the fan 52, achieves a high degree of synergy between spraying and airflow assistance, significantly improving the cooling uniformity, stability, and system integration level of the air-cooled island under high-temperature conditions. In this embodiment, the fan 52 can be an axial flow fan 52 in the existing structure. There are multiple fans 52, and the multiple fans 52 are arranged at intervals along the axial direction of the steam splitter pipe.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
