Description

Technical Field

[0001] The invention relates to the technical field of cooling tower water distribution, and in particular to a cooling tower micro-water distribution method and system. Background Art

[0002] In industrial production and power supply, cooling towers are an important cooling equipment widely used in cooling circulating water systems. Their main function is to reduce the temperature of cooling water by evaporative heat dissipation to maintain the normal operation of industrial systems. The working principle of cooling towers is to use filler layers to increase the contact area between air and water, thereby achieving the purpose of cooling water. In this process, the uniformity and efficiency of the water distribution system are crucial to the performance of the cooling tower.

[0003] Existing cooling tower water distribution systems usually include water distribution pipes and nozzles. These systems distribute water evenly to the filler area through nozzles to increase the contact area between water and air and promote heat exchange. However, these systems often lack the ability to accurately identify and handle water distribution blind areas. Water distribution blind areas refer to areas inside the cooling tower where water cannot be effectively distributed to certain areas due to design or operating conditions, resulting in low heat exchange efficiency in these areas. In the prior art, although some systems attempt to improve water distribution uniformity by increasing the number of nozzles or adjusting the position of nozzles, these methods often have limited effects and lack systematicity and precision.

[0004] Therefore, the traditional water distribution system has the following technical problems:

[0005] Uneven water distribution: The existing water distribution system cannot ensure that water is evenly distributed inside the cooling tower, especially in the edge areas of the cooling tower or areas with complex structures.

[0006] Water distribution blind area: Due to limitations in design or operating conditions, some areas cannot obtain sufficient water, forming a water distribution blind area and affecting the cooling effect.

[0007] Difficulties in monitoring and adjustment: The existing system lacks effective monitoring means to identify and address water distribution blind spots, and it is also difficult to adjust water distribution strategies based on real-time data.

[0008] Reduced cooling tower efficiency: Due to uneven water distribution and blind spots, the water flow in some areas is too large while the water flow in other areas is insufficient, resulting in reduced cooling tower efficiency. Summary of the invention

[0009] In view of the shortcomings of the prior art, the purpose of the embodiments of the present invention is to provide a method and system that can accurately identify and process the blind area of ​​water distribution in a cooling tower to achieve efficient micro-water distribution. Specifically: the micro-water distribution method and system realize the accurate identification and processing of water distribution inside the cooling tower, especially for the problem of blind area of ​​water distribution. The system uses sensor networks and data analysis models to accurately identify blind areas, and uses numerical calculations and visualization technology to assist in determining the location of blind areas. Then, a micro-water distribution scheme is customized according to the characteristics of the blind area, including selecting the appropriate nozzle type, quantity and installation method. For remote blind areas, a dedicated water distribution branch pipe is designed to ensure water supply. The system also includes a dynamic tracking module, which uses camera and image analysis technology and a water pressure monitoring system to monitor the water distribution status in real time to ensure stable operation of the system. The water balance calculation module ensures that the newly added blind area water distribution branch pipe works in coordination with the original system to avoid mutual interference. The micro-water distribution method and system improve the cooling efficiency and ensure efficient and accurate management of the cooling tower.

[0010] In order to achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

DETAILED DESCRIPTION

[0024] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0025] For ease of understanding, the micro-water distribution system is first explained:

[0026] like Figure 1 As shown, the bottom is a filling area 1, and the upper side of the filling area 1 is provided with a water distribution pipe 2, and the water distribution pipe 2 is provided with an original water distribution nozzle 4 and a special blind area nozzle 5. The original water distribution nozzle 4 forms an original water distribution coverage area 3, and the special blind area nozzle 5 covers the water distribution blind area 6. Figure 2As shown, a dedicated remote blind area water distribution pipe 8 is also provided on the water distribution pipe 2 , and the dedicated remote blind area water distribution pipe 8 covers the remote water distribution blind area 7 .

[0027] The cooling tower micro-water distribution system includes a blind spot identification module, a blind spot micro-water distribution matching module, a remote blind spot water distribution dedicated branch pipe module, a dynamic tracking module and a water balance calculation module. The modules work together to achieve precise water distribution in the cooling tower and improve cooling efficiency.

[0028] Blind spot recognition module

[0029] Function: Use a variety of sensors to collect cooling tower operation data, and combine data analysis models and visualization technology to accurately identify the water distribution blind areas of the operating cooling tower, and clarify their number, distribution, location and severity.

[0030] Implementation

[0031] The sensors in the blind spot identification module include but are not limited to temperature sensors, humidity sensors, flow velocity sensors and flow sensors, and the installation positions and acquisition frequencies of the sensors can meet the requirements of comprehensively and accurately monitoring the internal operating status of the cooling tower.

[0032] Temperature sensors, humidity sensors, flow rate sensors and flow sensors are arranged at key locations in the cooling tower to form a full-range monitoring network. These sensors collect data at a predetermined frequency, collecting temperature and humidity data once and flow rate and flow data once to ensure the timeliness and accuracy of the data.

[0033] A mathematical model is constructed based on the principles of fluid mechanics and heat exchange theory, and the massive amount of data collected is input into the model for in-depth analysis. The model comprehensively considers the temporal and spatial changes of multiple factors such as water temperature, humidity, flow rate, and flow rate, and evaluates the heat exchange efficiency and water flow distribution in each area through numerical calculation and analysis. For example, the heat exchange amount is calculated based on the temperature difference and water flow rate, and the water flow is judged based on the flow rate and flow rate to determine whether it is blocked or abnormally distributed.

[0034] Visualization technology is used to assist judgment, such as infrared thermal imaging technology to generate images of the temperature distribution inside the cooling tower. In the image, the low-temperature area corresponds to the heat exchange effect of the normal water distribution area, while the high-temperature area may indicate insufficient water distribution or a blind spot. By comparing the temperature with the normal area, the location and range of the blind area can be preliminarily determined.

[0035] At the same time, the analysis results of the sensor data model are combined and verified to further determine the exact location, number and distribution of blind spots.

[0036] The severity of the problem can be assessed quantitatively based on indicators such as the degree to which the heat exchange efficiency is below normal levels and the proportion of water flow loss. For example, an area where the heat exchange efficiency is 30% below the standard value and the water flow loss is more than 50% can be judged as a serious blind spot.

[0037] Blind zone micro water distribution matching module

[0038] Function: Based on the blind spot identification results, water balance calculation data and nozzle characteristics, scientifically match the nozzle type, quantity and installation method, determine the micro-water distribution transformation strategy, and clarify the nozzle action area.

[0039] The blind spot micro-water distribution matching module is used to determine the micro-water distribution modification method based on the blind spot information determined by the blind spot identification module, the calculation results of the water balance calculation module, and the characteristics and geometric dimensions of the nozzle, including matching the type, quantity and installation method of the nozzle, and clarifying the effective area of ​​the nozzle.

[0040] Implementation

[0041] Select the appropriate nozzle type according to the specific characteristics of the blind spot, such as shape, area, location and severity. For small and irregular blind spots, choose a nozzle with a small spray angle but good atomization effect to ensure that the water mist can accurately cover the blind spot; for large blind spots, choose a nozzle with a large spray angle and long range to improve coverage efficiency.

[0042] Accurately calculate the number of nozzles required, comprehensively consider the blind area, nozzle coverage and overlapping effect, so as to achieve the optimal configuration of the number of nozzles and ensure effective coverage of the blind area.

[0043] Carefully plan the nozzle installation method, including angle and height. Adjust the nozzle angle according to the air flow direction and heat exchange requirements. For example, in areas with strong air updrafts, tilt the nozzle downward at a certain angle to make the water mist and air flow in reverse, enhancing the air-water contact effect. Determine the nozzle height according to the cooling tower structure and blind spot position to ensure that the water mist is fully mixed with the air at the appropriate height. For example, install the nozzle at a certain distance above the filler area so that the water mist can be evenly distributed on the filler during the falling process, thereby improving the cooling efficiency.

[0044] Remote blind area water distribution dedicated branch pipe module

[0045] Function: A separate water distribution branch pipe is designed for the blind area far away from the central water distribution pipe 2 to ensure stable water supply.

[0046] Implementation

[0047] In view of the special location and water distribution requirements of the remote blind area, the diameter, length and material of the water distribution branch pipe are accurately designed based on fluid mechanics calculations. Through fluid mechanics calculations, the pipe diameter that can meet the water volume and pressure requirements of the remote blind area is determined. For example, according to the expected flow rate and allowable pressure loss of the remote blind area, the appropriate pipe diameter is selected to ensure that the water volume and pressure requirements of the remote blind area can be met. At the same time, the direction of the branch pipe is reasonably planned to avoid interference from other equipment and structures in the cooling tower. The selected material has the characteristics of corrosion resistance and high compressive strength, which can adapt to the complex working environment inside the cooling tower and ensure long-term stable water supply.

[0048] Reasonably plan the direction of the branch pipes to avoid interference from other equipment and structures in the cooling tower, and transport water to the remote blind area in the shortest path to reduce pressure loss. At the same time, install necessary control valves and monitoring equipment on the branch pipes, such as flow control valves and pressure sensors, to facilitate real-time regulation and monitoring of water flow, and ensure the accuracy and stability of water distribution in the remote blind area.

[0049] Dynamic tracking module

[0050] Function: With the help of rain area camera, image dynamic analysis technology and water pressure monitoring system, the operation status of the water distribution system is monitored in real time, and abnormalities are discovered and handled in time.

[0051] Implementation

[0052] High-definition cameras are installed at key locations in the rain zone of the cooling tower to capture the water flow from multiple angles and obtain clear images of the rain zone to meet the requirements of real-time monitoring of the water flow status. The camera shoots continuously to ensure that subtle changes in the water flow are captured.

[0053] Advanced image dynamic analysis algorithms are used to process the captured images in real time. The algorithm can identify the shape, speed and distribution changes of water flow, detect abnormal water flow in time and issue alarm signals. For example, the water flow speed is calculated by comparing the position changes of water droplets in adjacent frame images, and the uniformity of water distribution is judged according to the distribution density of water droplets. Once abnormal water flow is found, such as local interruption of flow, sudden change of water flow speed or serious uneven distribution, an alarm signal is immediately issued.

[0054] At the same time, the water pressure monitoring system monitors water pressure changes in real time by installing pressure sensors at key nodes of the water distribution pipeline. The accuracy and reliability of the pressure sensors can meet the requirements for accurately judging the working status of the water distribution system. The pressure sensor transmits water pressure data to the control system, which sets the normal water pressure range. When the water pressure exceeds this range, combined with the rain area image analysis results, it comprehensively judges whether there is a fault in the water distribution system, such as pipe blockage, water leakage or valve failure, and locates the fault point in time so that maintenance personnel can respond and handle it quickly.

[0055] Water balance calculation module

[0056] Function: Comprehensively analyze the water balance of the cooling tower water distribution system to ensure that the newly added blind area water distribution branch pipes work in coordination with the original system to avoid interference.

[0057] Implementation

[0058] Accurately measure and obtain the key parameters of the cooling tower, including the amount of water entering the tower (real-time measurement by a high-precision flow meter installed on the water inlet pipe), the amount of water leaving the tower (a flow meter is also installed on the water outlet pipe), and the amount of water lost by evaporation (calculated using empirical formulas based on factors such as ambient temperature, humidity, wind speed, and water temperature at the inlet and outlet of the tower, such as Q e = kAC(T in -T out ), where k is the evaporation coefficient, T in is the water temperature entering the tower, T out is the outlet water temperature, A is the air-water contact area, C is a constant), drift loss water volume (estimated based on the cooling tower structure and operating conditions), and water distribution volume in each area (obtained through flow sensor data in each area).

[0059] A sophisticated mathematical model of water balance is established, and the above parameters are included in the model for calculation and analysis. According to the law of conservation of matter, the model ensures that the amount of water entering the tower is equal to the sum of the amount of water leaving the tower, the amount of water lost by evaporation, the amount of water lost by drift, the amount of water distributed to each area, and the possible change in the amount of accumulated water in the system (the amount of accumulated water changes approaches zero during stable operation). By solving the model, the optimal water distribution plan is determined, including the flow setting of the blind area water distribution branch pipe and the flow adjustment of the original water distribution system. When adding a new blind area water distribution branch pipe, the model calculates its impact on the water balance of the entire system. By adjusting the water distribution amount in other areas or optimizing the design parameters of the branch pipe (such as pipe diameter and length), it ensures that the water balance of the system is not destroyed, the original water distribution area is not affected, and the generation of new blind areas is avoided.

[0060] Working principle of cooling tower micro water distribution system:

[0061] The blind spot identification module is started first to continuously collect and analyze data and accurately lock in all information on the water distribution blind spot.

[0062] The water balance calculation module runs synchronously, calculating the water balance based on the overall operation data of the cooling tower, providing basic data support for subsequent water distribution plans.

[0063] The blind spot micro-water distribution matching module selects suitable nozzles and plans installation plans based on the blind spot identification results and water balance calculation data, and determines the micro-water distribution transformation strategy.

[0064] The dedicated branch pipe module for water distribution in remote blind areas constructs an independent water supply channel for the remote blind areas according to the design plan to ensure the water demand of the remote blind areas.

[0065] The dynamic tracking module monitors the entire system operation process, finds problems and provides feedback in time through image and water pressure analysis to ensure that the system is always in good operating condition. Each module works closely together to form a closed-loop control to achieve efficient and accurate management of cooling tower water distribution.

[0066] This embodiment also provides a micro-water distribution method for a cooling tower, comprising the following steps:

[0067] Blind spot identification steps: Use the sensors in the blind spot identification module to collect cooling tower operation data, and determine the number, distribution, location and severity of water distribution blind spots through data analysis models and visualization technology;

[0068] Water balance calculation steps: Use the water balance calculation module to accurately measure and calculate the cooling tower's water inlet, water outlet, evaporation loss, drift loss, and water distribution in each area, establish a mathematical model, and calculate the system water balance;

[0069] Micro-water distribution plan formulation steps: Based on the results of the blind spot identification step and the water balance calculation step, the blind spot micro-water distribution matching module determines the micro-water distribution transformation method according to the nozzle characteristics and geometric dimensions, including selecting the nozzle type, calculating the number, planning the installation method, and clarifying the nozzle action area;

[0070] Remote blind area water distribution steps: Use the remote blind area water distribution special branch pipe module to design and install water distribution branches for the remote water distribution blind area to ensure water supply in the remote blind area;

[0071] Dynamic tracking steps: Utilize the rain area camera, image dynamic analysis technology and water pressure monitoring system in the dynamic tracking module to dynamically track and monitor the entire water distribution system, detect and handle abnormal situations in a timely manner, and ensure that all water distribution is in good condition.

[0072] In the blind spot identification step, the frequency of sensor data collection is set according to the operating characteristics and actual needs of the cooling tower to ensure the timeliness and effectiveness of the data.

[0073] In the water balance calculation step, for different types of cooling towers or different operating conditions, the calculation parameters of evaporation loss water and drift loss water can be adjusted to improve the accuracy of the water balance calculation.

[0074] In the process of formulating the micro-water distribution plan, the specific conditions of the blind area and the heat exchange and air flow requirements of the area should be considered when selecting the nozzle type to ensure that the nozzle and the blind area are optimally matched. When calculating the number of nozzles, the blind area, nozzle coverage and overlapping effects should be fully considered to ensure that the blind area can be evenly covered and the nozzles are not over-configured. When planning the nozzle installation method, optimize it according to the air flow direction and the structural characteristics of the cooling tower to ensure that the water mist is fully mixed with the air and improve the cooling efficiency.

[0075] In the remote blind area water distribution step, the design and installation of the water distribution branch pipe fully considers the location, distance, required water volume and pressure requirements of the remote blind area, as well as the spatial layout in the cooling tower and the influence of other equipment.

[0076] In the dynamic tracking step, the shooting angle and range of the rain zone camera system can cover the entire cooling tower rain zone, and the image analysis algorithm can process the captured images in real time and accurately determine the water flow status. The pressure sensor of the water pressure monitoring system is installed in a reasonable position, which can accurately reflect the water pressure conditions of key parts of the water distribution system and issue an alarm in time when the water pressure is abnormal.

[0077] In order to make the technical solution provided by the present invention clearer, the present invention is described with three embodiments:

[0078] Example 1

[0079] The micro water distribution system of the present invention is applied in a cooling tower of a large thermal power plant.

[0080] The blind spot identification module identified multiple water distribution blind spots through a dense sensor network and data analysis. One of them was located at the edge of the cooling tower, with an area of ​​approximately 30 square meters. The heat exchange efficiency was 40% lower than that of the normal area, and it was determined to be a severe blind spot. The other was close to the center but in a partially recessed area, with an area of ​​15 square meters. The heat exchange efficiency was 25% lower, and it was a moderate blind spot.

[0081] Based on the operating data of the cooling tower, the water balance calculation module calculates the water inlet volume of 1,000 cubic meters per hour, the water outlet volume of 950 cubic meters per hour, the evaporation loss volume of 30 cubic meters per hour, the drift loss volume of 5 cubic meters per hour, and the original water distribution volume of each area, and determines the flow distribution of the newly added blind area water distribution branch pipe accordingly.

[0082] For the severe blind area of ​​30 square meters, the blind spot micro-water distribution matching module selects a large-flow nozzle with a spray angle of 120 degrees and a range of 8 meters. It is calculated that 4 nozzles need to be installed, with the installation angle tilted downward by 30 degrees and the height being 1.5 meters above the packing layer; for the moderate blind area of ​​15 square meters, a medium-flow nozzle with a spray angle of 90 degrees and a range of 5 meters is selected, and 3 nozzles are installed, with the angle tilted downward by 20 degrees and the height being 1.2 meters.

[0083] The remote blind area water distribution branch pipe module is designed with a 20-meter-long, 80-mm-diameter stainless steel water distribution branch pipe for severe blind areas in the edge areas to ensure sufficient pressure and water supply.

[0084] During operation, the dynamic tracking module promptly discovered abnormal water flow caused by nozzle blockage through rain area camera and image analysis. At the same time, the water pressure monitoring system detected the increase in water pressure in the corresponding area, and the system quickly issued an alarm, and maintenance personnel quickly repaired it according to the location. After debugging and a period of operation, the overall cooling efficiency of the cooling tower increased by 20%, the water temperature out of the tower decreased by 3 degrees Celsius, and the water resource utilization rate increased by 18%.

[0085] Example 2

[0086] The micro-water distribution system of the present invention is applied to the cooling tower of a chemical enterprise.

[0087] Blind spot recognition module

[0088] The internal environment of the cooling tower is complex, and the corrosive gases and high water temperature generated by the chemical process have a great impact on the water distribution system. The sensor network in the blind spot recognition module continues to work stably in this harsh environment and collects a large amount of data. Through detailed analysis of data such as temperature, humidity, flow rate and flow, it was found that the local area above the cooling tower was poorly ventilated and corrosive gases eroded, resulting in partial blockage of the water distribution nozzles, forming a water distribution blind area. According to calculations, the area of ​​this blind area is about 25 square meters, and the heat exchange efficiency is 35% lower than that of the normal area.

[0089] Visualization technology played an important role in this inspection. Infrared thermal imaging showed that the temperature in this area was significantly higher than the surrounding area, and the temperature distribution was uneven, which further confirmed the results of sensor data analysis and accurately located the blind spot.

[0090] Water balance calculation module

[0091] Considering the special working conditions of chemical cooling towers, the water balance calculation module has made targeted adjustments to various parameters. Due to the high water temperature and the presence of corrosive gases, the evaporation coefficient in the calculation of evaporation loss water volume has been corrected according to the actual environmental conditions. At the same time, the estimation of drift loss water volume also fully considers the gas flow characteristics and the influence of chemicals on water droplets.

[0092] Blind zone micro water distribution matching module

[0093] In view of the corrosiveness of the chemical environment, the blind area micro-water distribution matching module carefully selects nozzles with good atomization effect made of corrosion-resistant materials. These nozzles can not only work stably for a long time in harsh environments, but also their special atomization structure can make the water mist more dense and uniform, which is conducive to increasing the air-water contact area in poorly ventilated areas.

[0094] After precise calculation, it was determined that 5 nozzles would be installed in the 25 square meter blind area. The installation angle was optimized according to the ventilation direction and the shape of the blind area, so that the water mist could be fully diffused in the area and effectively mixed with the air. The nozzle height was set at 1.3 meters above the packing layer to ensure that the water mist could evenly cover the packing during the falling process, thereby improving the cooling effect.

[0095] Remote blind area water distribution dedicated branch pipe module

[0096] Since the blind area is located at the top of the cooling tower, the remote blind area water distribution branch pipe module is designed with a special support structure for the water distribution branch pipe. The support structure is made of corrosion-resistant and high-temperature resistant alloy materials, which can resist corrosion and high temperature in the chemical environment and ensure the stability of the branch pipe.

[0097] The branch pipe diameter was precisely calculated to be 75 mm, and the length was designed to be 18 meters based on the actual layout. It is made of high-strength, corrosion-resistant plastic material, which can not only meet the water distribution needs of the blind area, but also effectively reduce costs and weight. The branch pipe avoids other equipment and high-temperature and high-corrosion areas, ensuring that water can be delivered to the blind area unimpeded.

[0098] Dynamic tracking module

[0099] During operation, the dynamic tracking module closely monitors the system status. The rain zone camera system promptly captures the local blockage of the pipeline caused by chemical deposition, and the image analysis algorithm quickly identifies abnormal changes in water flow morphology and distribution by comparing before and after images.

[0100] The water pressure monitoring system also detected an increase in water pressure in the corresponding area, which was confirmed by the image analysis results. The system quickly issued an alarm, and maintenance personnel quickly arrived at the fault site to repair it based on the accurate location information provided by the dynamic tracking module. By promptly cleaning the sediment in the pipe, normal water distribution was restored, ensuring the stable operation of the cooling tower.

[0101] Implementation Effect

[0102] After a period of operation, the cooling tower has effectively solved the problem of local overheating. The cooling energy consumption has been reduced by 16%, significantly saving energy costs. The equipment maintenance cycle has been extended by 30%, reducing the downtime caused by frequent maintenance and improving production efficiency. At the same time, the water temperature out of the tower is more stable and meets the process requirements, ensuring the stability of the chemical production process and product quality.

[0103] Example 3

[0104] The micro water distribution system of the present invention is applied in a cooling tower of a data center.

[0105] Blind spot recognition module

[0106] Data centers have extremely high requirements for the stability and reliability of cooling tower operation. The sensors in the blind spot identification module collect data at a high frequency to ensure real-time and accurate monitoring of the cooling tower's operating status. Analysis found that due to the layout of the data center equipment, a water distribution blind spot appeared on the side of the cooling tower near the server area. The blind spot covers an area of ​​about 20 square meters and has a 30% lower heat exchange efficiency, mainly because the heat generated by the nearby servers interferes with the air flow, resulting in uneven water distribution.

[0107] Visualization technology presents the unique temperature and humidity distribution characteristics of the area, which is in sharp contrast with other normal areas, providing an intuitive basis for accurately judging blind spots.

[0108] Water balance calculation module

[0109] The water balance calculation module fully considers the special operating environment of the data center cooling tower. Since the indoor environment is relatively stable and the humidity is strictly controlled, the calculation of evaporation loss water is more precise, referring to the indoor air humidity set value and actual fluctuation range. At the same time, according to the server's cooling requirements and operating load, the theoretical water distribution in different areas is accurately calculated.

[0110] Blind zone micro water distribution matching module

[0111] In view of the fact that the blind area is close to the server and has high requirements for cooling stability, the blind area micro-water distribution matching module selects low-noise, high-precision nozzles. These nozzles can meet the cooling needs while not causing noise interference to the working environment of the data center.

[0112] Calculations determined that four nozzles were installed, and the installation angles were optimized according to the server layout and air flow direction to ensure that the water mist could accurately cover the blind spots without affecting the normal operation of the server. The nozzle height was set 1.2 meters above the packing layer to ensure good air-water contact.

[0113] Dynamic tracking module

[0114] The dynamic tracking module plays a key role in the data center cooling tower. The rain zone camera system monitors the water flow status in real time, and the image analysis algorithm can quickly detect any slight water flow anomalies, such as uneven spraying of sprinklers due to dust accumulation.

[0115] The water pressure monitoring system closely monitors water pressure changes. Once an abnormality is found, it immediately combines the image analysis results to determine the fault type and location. The system quickly issues an alarm, and maintenance personnel can handle it in a timely manner based on detailed fault information, ensuring that the cooling tower operates uninterruptedly and providing stable and reliable cooling services for data center servers.

[0116] Implementation Effect

[0117] After applying the present invention, the cooling tower has significantly improved cooling efficiency, and the server operating temperature is always kept within a safe range, ensuring the efficient and stable operation of the data center. The number of system failures has been reduced by 40%, greatly improving the reliability of the system and reducing the risk of data center downtime due to cooling tower failure. At the same time, the water resource utilization rate has increased by 20%, which is in line with the development trend of green energy conservation in data centers.

[0118] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
