[0026] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. used in the present invention to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices and elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In the description of this utility model, it should be understood that the terms "first," "second," etc. are used to describe various types of information, but such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information without departing from the scope of this utility model.

[0029] Among current cooling technologies, combined dry-wet cooling towers, featuring a dual-module design combining dry and wet cooling modules, offer exceptional cooling performance. In this design, the dry cooling module utilizes heat sink fins outside the heat exchange pipes as a heat exchange medium. When high-temperature hot water flows through the pipes, the fins transfer heat to the ambient environment, achieving dry heat dissipation without requiring additional water consumption. The wet cooling module sprays cooling water directly onto the heat exchange pipes via a spray cooler or spray pipe, rapidly lowering the water temperature using the water's latent heat of evaporation, achieving efficient wet heat dissipation. However, practical applications present a significant challenge: because the dry cooling module is positioned above the wet cooling module, sharing the same air duct and arranged vertically, the fins are susceptible to water vapor generated by the evaporation of the sprayed water below. Over time, this rising water vapor condenses and accumulates on the fin surfaces, causing corrosion in the fin structure. This not only impairs the performance of the dry cooling module but also negatively impacts the efficiency and lifespan of the entire cooling tower.

[0030] Based on this, Figures 1 to 5 As shown, an embodiment of the present invention provides a cooling tower 100, which includes a mounting bracket 30, a heat exchange pipe 40, a first cooling module 10 and a second cooling module 20. The first cooling module 10 and the second cooling module 20 are arranged along the length direction of the mounting bracket 30; the first cooling module 10 includes a first fan 11 and a water-cooling component 12, and the second cooling module 20 includes a second fan 21 and heat dissipating fins 22. The first fan 11 and the second fan 21 are arranged on the mounting bracket 30, and the heat exchange pipe 40 passes through the water-cooling component 12 and the heat dissipating fins 22. The first fan 11 blows toward the water-cooling component 12, and the second fan 21 blows toward the heat dissipating fins 22.

[0031] Based on the above technical solution, the cooling tower 100 of this embodiment integrates two cooling modules, wet cooling and dry cooling. The first cooling module 10 serves as a wet cooling module, and the second cooling module 20 serves as a dry cooling module. When the cooling tower 100 is in operation, the medium to be cooled circulates in the heat exchange pipe 40. After startup, the second fan 21 blows toward the heat dissipating fins 22, promoting the heat of the medium to be dissipated into the outside air through the heat dissipating fins 22, thereby achieving dry cooling. At the same time, the first fan 11 blows toward the water-cooling component 12, accelerating the water evaporation process by enhancing air flow, thereby absorbing and taking away a large amount of heat from the medium in the heat exchange pipe 40, thereby completing wet cooling. In this embodiment, the first cooling module 10 and the second cooling module 20 are arranged in sequence along the length direction of the mounting bracket 30, which not only optimizes the spatial layout but also constructs two independent air duct systems, ensuring that the first fan 11 and the second fan 21 operate independently without interfering with each other, preventing the water vapor generated in the wet cooling module from contacting the surface of the heat dissipation fins 22 of the dry cooling module, thereby avoiding the problem of water vapor condensation and accumulation on the heat dissipation fins 22, and ensuring the safe, efficient and stable operation of the cooling tower 100.

[0032] In this embodiment, the cooling tower 100 is divided into two independent modules, namely a wet cooling module (first cooling module 10) and a dry cooling module (second cooling module 20). This modular design allows each module to be maintained and repaired separately without affecting the operation of the entire cooling tower 100. Maintenance personnel can inspect and repair key components of each module separately, such as fans, heat exchange pipes, heat dissipation fins, etc.

[0033] As an embodiment, the heat exchange pipe 40 is arranged in a coiled structure between the first cooling module 10 and the second cooling module 20 , and a plurality of heat dissipation fins 22 are provided in the second cooling module 20 .

[0034] Specifically, the coiled structure of the heat exchange pipe 40 significantly increases the pipe length, thereby providing more heat exchange area. This allows for more efficient heat transfer from the medium within the pipe to the cooling module within the same cooling time. The large number of heat dissipating fins 22 provided in the second cooling module 20 also increases the heat exchange area and improves heat exchange efficiency.

[0035] In practical applications, adaptive adjustments are made based on the two cooling modules. Since the wet cooling module consumes a large amount of water for evaporative cooling during operation, reducing its operating time or stopping it can reduce water consumption, a particularly significant advantage in areas with water shortages. When the temperature is low, the heat dissipation capacity of the fins 22 gradually increases or can fully provide heat exchange capacity, allowing the wet cooling module to partially or not participate in heat dissipation, thereby saving water.

[0036] As an implementation method, Figure 1 、 Figure 2 and Figure 3 As shown, the first fan 11 is disposed on the top of the water cooling assembly 12 , and the second fan 21 is disposed on the top of the heat dissipation fins 22 .

[0037] Specifically, for the wet cooling module, the first fan 11 is located at the top of the water-cooling assembly 12 and can blow a large amount of air directly downward. This top-down air supply method increases the contact area between the air and the water surface in the water-cooling assembly 12, promotes the improvement of water evaporation efficiency, and thus more efficiently absorbs the heat of the medium in the heat exchange pipe 40. For the dry cooling module, the second fan 21 is located at the top of the heat dissipation fins 22 to achieve direct blowing cooling of the surface of the heat dissipation fins 22, so that air can flow evenly through the gaps between the heat dissipation fins 22, increase the heat exchange area, and accelerate the transfer of heat from the fin surface to the air. In addition, the fan arranged at the top can also prevent dust and other pollutants on the ground from contaminating the heat dissipation fins 22, thereby extending the service life and maintenance cycle of the cooling tower 100.

[0038] As an implementation method, Figure 5 As shown, the first fan 11 and the second fan 21 are arranged adjacent to each other.

[0039] Specifically, the adjacent first fan 11 and the second fan 21 help save installation space. In a limited space, the two fans are compactly arranged together to maximize the use of space resources and reduce unnecessary floor space.

[0040] As an implementation method, Figure 3 As shown, the water cooling component 12 includes a water collecting tank 121, a spray pipe and a spray pump 122. The water collecting tank 121 and the spray pump 122 are arranged at the bottom of the heat exchange pipe 40. The inlet of the spray pump 122 is connected to the water collecting tank 121, and the outlet of the spray pump 122 is connected to the inlet section of the spray pipe. The outlet section of the spray pipe extends between the heat exchange pipe 40 and the first fan 11.

[0041] Specifically, the water in the sump 121 is pumped to the spray pipe by the spray pump 122, and then sprayed onto the heat exchange pipe 40. The water evaporates rapidly and absorbs heat, thus achieving efficient heat exchange. The design of the sump 121 allows the sprayed water to flow back and be pumped back into the spray pump 122 for reuse, achieving water recycling, reducing water consumption, and lowering operating costs.

[0042] It is understood that the spray pump 122 is located at the bottom of the heat exchange pipe 40, while the outlet section of the spray pipe is located above the heat exchange pipe 40, making the water cooling assembly 12 compact and occupying a small area. The water cooling assembly 12 of this embodiment provides a strong guarantee for the operation of the cooling tower 100 through the technical effects of efficient heat exchange, water-saving design, compact structure, and easy maintenance.

[0043] As an implementation method, Figure 3 As shown, the outlet section of the spray pipe is provided with a plurality of spray heads 123 facing the heat exchange pipe 40 at intervals.

[0044] Specifically, this embodiment achieves uniform water mist spraying by disposing multiple nozzles 123 at intervals at the outlet of the spray pipe. This increases the contact area between the water mist and the surface of the heat exchange pipe 40, accelerates the heat exchange process, and improves heat exchange efficiency. This uniform, multi-point spraying method enhances the heat dissipation effect of the water cooling assembly 12, avoids local overheating of the heat exchange pipe 40, ensures uniform temperature distribution throughout the heat exchange pipe 40, and extends the service life of the heat exchange pipe 40.

[0045] As an embodiment, the water cooling assembly 12 includes a water collector (not shown in the drawings), which is arranged between the spray pipe and the first fan 11 .

[0046] Specifically, after the spray pipe sprays water mist or water droplets onto the heat exchange pipe 40, part of the water will evaporate to take away the heat, while the other part may be suspended in the air in the form of water droplets. The setting of the water collector can effectively intercept these suspended water droplets, preventing them from being sucked into the first fan 11 and discharged into the atmosphere, thereby reducing the loss of cooling water. The water droplets intercepted by the water collector can be collected and returned to the water collection tank 121 through the pipeline system to achieve the recycling of cooling water. In actual application, the water collector can be an M-type PVC corrugated board for filler, and the PVC corrugated board is arranged above the spray pipe and below the first fan 11, thereby collecting the spray water.

[0047] As an embodiment, the first fan 11 and the second fan 21 are detachably mounted on the mounting bracket 30 .

[0048] Specifically, from a maintenance and replacement perspective, when fans require routine maintenance, cleaning, or component replacement, operators can complete the work quickly and efficiently, minimizing downtime and ensuring continuous and stable operation of the cooling tower 100 system. Fan configuration can be flexibly adjusted based on actual needs. Whether responding to seasonal changes or load fluctuations, the number of fans can be increased or decreased to optimize cooling performance and energy efficiency.

[0049] As an embodiment, the cooling tower 100 includes a controller, and the first fan 11 and the second fan 21 are electrically connected to the controller.

[0050] Specifically, the controller can monitor environmental parameters and system status in real time, accurately adjust the speed and air volume of the first fan 11 and the second fan 21 according to actual needs, accurately control the cooling process, and achieve the goal of energy saving and consumption reduction. At the same time, the controller has fault warning and real-time protection functions. Once the fan operation is detected to be abnormal, it reminds the staff to take measures to prevent the fault from expanding and ensure the stable operation of the system. In addition, this intelligent control strategy also promotes the collaborative work between fans, improving the overall efficiency and response speed of the system. The controller supports remote monitoring and maintenance functions, allowing operators to easily perform fault diagnosis, debugging and upgrade work, reducing maintenance costs.

[0051] As an embodiment, the number of the first fans 11 is at least two, and the number of the second fans 21 is at least two.

[0052] For example, Figure 2 As shown, there are two first fans 11 and four second fans 21 . The two first fans 11 are arranged along the length direction of the mounting bracket 30 , and the four second fans 21 are arranged in a rectangular array.

[0053] Specifically, the two first fans 11 are arranged along the length direction of the mounting bracket 30, achieving uniform distribution of airflow in the horizontal direction. The four second fans 21 are arranged in a rectangular array, which improves the cooling air volume and cooling efficiency. The increase in the number and layout of fans not only improves the cooling effect, but also improves the stability and reliability of the system through redundant design. Even if one of the fans fails, the other fans can continue to work, avoiding the complete shutdown of the cooling tower 100.

[0054] In a second aspect, an embodiment of the present invention provides a cooling system, including a cooling tower 100 .

[0055] Specifically, the cooling system includes not only the cooling tower 100 of the aforementioned embodiment but also a water replenishment system. During the cooling process, the amount of water in the sump 121 gradually decreases due to evaporation, leakage, and other factors. The water replenishment system monitors the water level in the sump 121 in real time and automatically replenishes water when the level falls below a set threshold, ensuring that the water level in the sump 121 remains stable, thereby ensuring the normal operation of the cooling system.
