Technical Field
[0001] The utility model relates to the technical field of liquid cooling circulation, in particular to a liquid cooling circulation water replenishing system. Background Art
[0002] The resistance load box is mainly used for performance detection, aging and other occasions of on-line high-power UPS, inverters, switching power supplies and diesel generator sets in departments such as electric power and telecommunications and manufacturers. When the resistance load box operates, it needs to be cooled by air cooling or liquid cooling. For large generator sets, in order to prevent the load box from being overloaded and burned out, liquid cooling circulation is generally used to cool the load box. Among common liquid cooling media, water is the most economical choice, and the temperature of water can be reduced more quickly through a cooling tower, so as to achieve more efficient liquid cooling.
[0003] In the existing liquid cooling circulation system, water replenishment is directly connected through a water supply pipe, and a water pump is arranged on the water supply pipe to control the water replenishment volume during the water replenishment process. However, due to certain delays and lags in the frequency converter adjustment of the water pump itself, the adjustment of the water replenishment volume will be untimely or excessive, which will lead to too high or too low water level in the cooling tower, resulting in too large or too small water volume in the circulating pipeline, thus affecting the cooling effect of the circulating water, and further making the resistance load box as the object to be cooled unable to dissipate heat effectively.
[0004] In view of this, it is necessary to develop a liquid cooling circulation water replenishing system with stable water replenishment volume to effectively make up for the deficiencies of the existing technology. Summary of the Utility Model
[0005] The utility model aims to provide a liquid cooling circulation water replenishing system, which optimizes the structure of circulating water replenishment to solve the technical problem that the existing system has poor cooling effect due to untimely water replenishment.
[0006] To solve the above problems, the utility model adopts the following technical scheme: A liquid cooling circulation water replenishing system includes a water storage tank, a cooling tower and an equipment resistance load box; the water storage tank is located below the cooling tower, and a water softening device for softening tap water is connected between the water storage tank and the tap water pipe; a liquid level controller for monitoring the liquid level height of the water storage tank is arranged at the top of the water storage tank; a closed circulating water circuit is formed among the water storage tank, the cooling tower and the resistance load box.
[0007] The principle and advantages of this solution are as follows: A closed circulating water loop is formed among the water storage tank, the cooling tower, and the resistive load box. The water storage tank is used to store water volume and can replenish water in a timely manner to ensure that there is sufficient water available for the resistive load box when needed, enabling timely heat dissipation. That is to say, the water storage tank can provide a stable water source for the entire system, ensuring the stable and continuous operation of the liquid cooling circulating water replenishment system. The cooling tower is used to cool the hot water from the resistive load box, and after its temperature is reduced, it returns to the water storage tank again, thus realizing circular use. The soft water device is used to treat the municipal tap water, that is, to perform softening treatment to reduce impurities in the water and reduce dirt in the pipelines and equipment, thereby improving the operating efficiency and service life of the system.
[0008] The water storage tank is located below the cooling tower. Due to the special arrangement of the cooling tower and the water storage tank, the cooling water in the cooling tower will automatically flow into the water storage tank under the action of gravity, making the liquid levels of the water storage tank and the cooling tower automatically remain the same. A liquid level controller for monitoring the liquid level height of the water storage tank is provided at the top of the water storage tank. When the liquid levels of the water storage tank and the cooling tower are the same, a single liquid level sensor can be used to detect the liquid levels of both the cooling tower and the water storage tank, and the liquid level change can be controlled through a PLC, achieving precise control of the liquid level, simplifying the control and management of the system, helping to improve the overall efficiency of the system, reducing energy loss, and ensuring a stable supply of cooling water.

[0017] Beneficial effects: The design of the load box water inlet and the load box water outlet enables cold water to enter the resistance load box from the bottom, forming a flow path from bottom to top, ensuring that the heat in the entire load box can be evenly carried away.
[0018] Preferably, as an improvement, the liquid level controller is a liquid level sensor or a liquid level gauge.

[0028] Beneficial effects of the present utility model: The present utility model provides a stable liquid cooling circulation water replenishing system, which can continuously and stably replenish water and improve the cooling effect. Through the combined use of the carefully designed water storage tank structure, cooling tower structure, water flow control device and the double treatment of municipal tap water, while ensuring continuous and stable water replenishment, the occupied space of the system is optimized and the flow rate can be accurately controlled, ensuring the efficient operation of the system and extending the service life of the system, and reducing its energy loss.
[0029] The water storage tank adopts a square structure with a height of 1.5 meters, and the cooling tower has a height of 2 meters and is located above the water storage tank. This layout not only optimizes the occupied space, but also utilizes the gravity to provide sufficient water pressure to ensure that the system can supply water stably and continuously. In addition, the square structure is convenient for installation and maintenance and has good stability.
[0030] The dual treatment of municipal tap water includes softening treatment, filtration and sewage treatment. First, the municipal tap water is softened by a water softening device to remove hard components such as calcium and magnesium ions in the water, thereby reducing the water hardness and reducing scale formation in pipelines and equipment. Then, the softened water after softening treatment is further filtered through a filter to remove residual impurities in the water, and through the cooling tower drain port and cooling tower drain valve at the bottom of the cooling tower and the water tank drain port and water tank drain valve at the bottom of the water storage tank, which are used to regularly discharge sediments and impurities in the cooling tower and water storage tank to ensure clean water quality. This dual treatment method reduces the blockage of the system, thereby improving the cooling efficiency of the system and extending the service life of the entire system.
[0031] By using a combination of various control devices, the system can achieve precise control of the water volume, ensure corresponding adjustments according to different water level conditions, and timely supplement the water volume in the water storage tank to keep it in a normal state. That is, through the combined use of an electromagnetic switch valve, a circulating water pump group, and a check valve to achieve adjustment of different water level conditions. Among them, the electromagnetic switch valve automatically controls the inlet and outlet of soft water in the water softening device through a PLC signal to achieve precise control of the water in the water softening device. The circulating water pump group controls the water circulation flow by reducing the pump frequency or switch state. The check valve not only controls the water volume flowing to the resistance load box but also prevents water from flowing back from the resistance load box to the water storage tank, avoiding chaotic water circulation. The coordinated action of these control devices not only improves the response accuracy of the system but also reduces energy consumption and extends the service life of the system.
[0032] In summary, through the optimized spatial layout of the water storage tank and the cooling tower, the present utility model ensures that the system can continuously and stably perform circulating water replenishment, meeting various cooling requirements. Through dual treatment - softening treatment and filtration and sewage treatment, the water quality in the system is significantly improved, reducing the accumulation of impurities and dirt, thereby improving the cooling effect and the overall performance of the system, and extending the service life of the entire system. And through the combined use of an electromagnetic switch valve, a circulating water pump group, and a check valve, precise control of the water volume is achieved, further improving the cooling effect of the system and reducing energy loss.

[0038] Example 1:
[0039] The embodiment is basically as Figure 1 shown. A liquid cooling circulation water replenishment system includes: a soft water device 1, a water storage tank 4, a resistance load box 14, and a cooling tower 17.

A load box water inlet 13 is provided at the lower left of the resistance load box 14, and a load box water outlet 15 is provided at the upper left.
[0040] The water inlet end of the soft water device 1 is connected to municipal tap water, and the water outlet end is connected with an electromagnetic switch valve 2; the water tank water replenishment port 3 is connected to the outlet pipeline of the electromagnetic switch valve 2 through a flange, the water tank water inlet 8 is connected to the cooling tower water outlet 18 through a flange and a pipeline, the water tank water outlet 9 is connected to the inlet of the circulating water pump group 11 through a flange and a pipeline, the cooling tower 17 is placed above the water storage tank 4, and the cooling tower water inlet 16 is connected to the load box water outlet 15 through a flange and a pipeline; the outlet pipeline of the circulating water pump group 11 is connected to the load box water inlet 13 through a flange to form a closed circulating water circuit.
[0041] Specifically, the water inlet end of the soft water device 1 is connected to municipal tap water, which softens the municipal tap water, reduces the hardness of the municipal tap water, and reduces the dirt in the municipal tap water. The water outlet end of the soft water device 1 is provided with an electromagnetic switch valve 2. The inlet pipeline of the soft water device 1 and the electromagnetic switch valve 2 is connected by a thread, and the voltage of the electromagnetic switch valve 2 is 24V / DC.
[0042] The outlet pipe of the electromagnetic switch valve 2 is connected to the water storage tank 4, that is, the outlet pipe of the electromagnetic switch valve 2 is flange-connected to the water replenishing port 3 of the water tank. The water inlet 8 of the water tank is connected to the water outlet 18 of the cooling tower through a flange and a pipe. The cooling tower 17 is placed above the water storage tank 4, and the bottom of the cooling tower 17 is higher than the top of the water storage tank 4, so that the water in the cooling tower 17 can flow naturally to the water storage tank 4 by gravity, reducing unnecessary power loss. The water outlet 9 of the water tank is connected to the inlet of the circulating water pump group 11 through a flange and a pipe. A filter 10 is provided between the water outlet 9 of the water tank and the circulating water pump group 11. The inlet and outlet pipelines of the filter 10 are flange-connected. The filter 10 is to further remove impurities in the municipal tap water. A liquid level controller 7 is provided on the top of the water storage tank 4 to monitor the water level; a water tank drain ball valve 6 connected by a flange and a pipe is installed on the left side of the water tank drain port 5, and a water pool is connected to the left side of the water tank drain ball valve 6.
[0043] The water inlet 16 of the cooling tower is connected to the water outlet 15 of the load box through a flange and a pipe. The cooling tower drain port 20 is connected to a cooling tower drain ball valve 21 through a flange and a pipe, and a water pool is connected to the left side of the cooling tower drain ball valve 21;
[0044] The outlet pipe on the right side of the circulating water pump group 11 is flange-connected to the water inlet 13 of the load box. A check valve 12 is provided between the circulating water pump group 11 and the water inlet 13 of the load box. The inlet and outlet pipelines of the check valve 12 are connected by welding. In this embodiment, the circulating water pump group 11 is composed of two parallel pumps and four butterfly valves. In this embodiment, the water in the water pool can flow to the soft water device 1 for system water replenishment.
[0045] The liquid cooling circulation water replenishment system adopted in this solution optimizes the structures and positions of the water storage tank 4 and the cooling tower 17, ensuring that there is always enough water in the system to be replenished in a timely manner, enabling the system to continuously and stably carry out water replenishment, meet various cooling requirements, ensuring that there is always enough water in the system to be replenished in a timely manner, thus guaranteeing the stable and continuous operation of the liquid cooling circulation water replenishment system. At the same time, under the action of gravity, the cooling water in the cooling tower 17 can naturally flow into the water storage tank 4 to keep the liquid levels of the two consistent, which not only simplifies the water replenishment process but also effectively reduces the floor space occupied by the entire system, making the layout more compact. In addition, compared with the traditional liquid cooling circulation, it can significantly reduce the waste of water resources. That is, the water discharged from the water tank drain port 5 and the cooling tower drain port 20 in this solution will be discharged into the pool and left to stand, and after being softened by the water softening device 1, it can be recycled again, reducing the consumption of tap water. By softening the municipal tap water through the water softening device 1 and through the drain port, drain ball valve, and filter 10, it can effectively reduce the dirt blocking the pipeline in the water circulation, reduce the water flow loss while extending the service life of the equipment, thereby improving the quality of the circulating water, reducing the probability of pipeline blockage, and improving the cooling effect of the circulating water. The water tank drain ball valve 6 and the cooling tower drain ball valve 21 can not only control whether to drain sewage but also control the change of the water level. When the water levels in the water storage tank 4 and the cooling tower 17 are not within the normal range, the change of the water level can be controlled by adjusting the opening degrees of the water tank drain ball valve 6 and the cooling tower drain ball valve 21, enhancing the control of the water level.
[0046] Embodiment 2:
[0047] The difference between Embodiment 2 and Embodiment 1 is only that the structure of the water storage tank 4 is a square structure and the height of the water storage tank 4 is 1.5 meters. The four vertical sides and one horizontal bottom surface can evenly distribute the pressure, ensuring the uniform pressure inside the water storage tank 4, thereby making the feedback data of the liquid level controller 7 more accurate, improving the accuracy and response speed of water level monitoring, and ensuring the stability and reliability of the system. At the same time, the height of the cooling tower 17 is 2 meters.
[0048] Specifically, a water tank make-up port 3 is provided at a position 1 meter above the bottom on the left side of the water storage tank 4. When the water tank make-up port 3 is filled with water from above, the disturbance to the existing water in the water storage tank 4 is reduced, which helps to maintain the stability of the water, thereby improving the accuracy of the water level monitoring of the liquid level controller 7. At the same time, the newly added water will gradually flow downward and mix with the original water, reducing the agitation of sediments; a water tank drain port 5 is provided at the left bottom, which can effectively discharge the sediments, sludge and impurities accumulated at the bottom of the water storage tank 4; a water tank inlet 8 is provided at the top right of the water storage tank 4 to reduce the disturbance to the existing water in the water storage tank 4 and maintain the stability of the water; a water tank outlet 9 is provided at a position 0.2 meters above the bottom on the right side of the water storage tank 4. When discharging water, gravity drainage can be used to reduce the pumping requirement and save energy. At the same time, it ensures that the water level in the water storage tank 4 drops smoothly, avoiding violent changes in the water level caused by rapid drainage. A cooling tower full water port 19 is provided at a position 1.5 meters above the bottom of the cooling tower 17 on the left side of the cooling tower 17 to ensure that the water level in the cooling tower 17 will not be too high, and the excess water will flow out through the cooling tower full water port 19, thus preventing water overflow; a cooling tower drain port 20 is provided at the left bottom, a cooling tower inlet 16 is provided at a position 0.5 meters above the bottom of the cooling tower 17 on the right side of the cooling tower 17, and a cooling tower outlet 18 is provided at a position 0.2 meters above the bottom on the right side, which is the same as the structural design of the water storage tank 4. The settings of the structures of the water storage tank 4 and the cooling tower 17 optimize the water flow distribution, enabling continuous and stable water replenishment and improving the overall performance and reliability of the system.
[0049] In addition, wooden blocks are provided on both sides of the bottom of the water storage tank 4 to raise the water storage tank 4 to prevent the ground from accumulating water and causing corrosion of the water storage tank 4 body, reducing the corrosion risk and extending the service life of the water storage tank 4. The cooling tower 17 is placed above the water storage tank 4 and connected by pipes. At the same time, the bottom of the cooling tower 17 is higher than the top of the water storage tank 4, so that the water in the cooling tower 17 can flow naturally to the water storage tank 4 by gravity, so that the liquid levels of the water storage tank 4 and the cooling tower 17 are kept consistent, reducing unnecessary energy loss and ensuring that the water storage tank 4 always has enough water for timely replenishment, thereby improving the cooling efficiency.
[0050] In this solution, the special structure and position settings of the water storage tank 4 not only ensure that there is enough water for technical replenishment, but also reduce the occupied space of the system, while reducing unnecessary power loss, ensuring the stability and reliability of the system, and improving the cooling effect.
[0051] Embodiment 3:
[0052] The difference between Embodiment 3 and Embodiment 1 is only that, as Figure 1As shown, the liquid level controller 7 adopted in this embodiment is a liquid level sensor. An openable and closable exhaust port 43 is provided at the top of the water storage tank 4, and an M20×1.5 internal thread joint is provided for connecting the liquid level sensor. The cable of the liquid level sensor is directly suspended into the water storage tank 4 to monitor the water level. The monitoring range of the water level height of the liquid level sensor is 0 to 1.5 meters. The liquid level sensor can monitor the water level change of the entire water storage tank 4 in real time and accurately, and adjust the water levels of the water storage tank 4 and the cooling tower 17 in a timely manner, so that the water level of the cooling tower 17 will not be too high or too low, and there will be no water shortage / overflow situation, ensuring the efficient and stable operation of the liquid cooling cycle, and preventing the resistance load box 14 from having a situation of untimely heat dissipation. In this embodiment, the normal water level is set to 0.6 to 0.9 meters. When the water level is lower or higher than the normal water level, the start and stop of the electromagnetic switch valve 2 and the circulating water pump group 11 will be automatically adjusted by the PLC.
[0053] Specifically, in this embodiment, in the normal production state, the water levels of the water storage tank 4 and the cooling tower 17 are about 50%. At this time, the electromagnetic switch valve 2 is in the closed state, and the soft water generated by the soft water device 1 will not enter through the water tank water replenishment port 3. The two water pumps of the circulating water pump group 11 operate at the normal frequency. The water tank drain ball valve 6 and the cooling tower drain ball valve 21 are in the semi-open state. The water in the water tank drain port 520 and the cooling tower drain port 20 will flow into the water pool and be recycled through the soft water device 1; the water in the water storage tank 4 flows out from the water tank water outlet 9, flows through the filter 10, the circulating water pump group 11 and the check valve 12, and then enters the resistance load box 14 through the load box water inlet 13 for heat dissipation, flows out from the load box water outlet 15, and flows into the cooling tower 17 through the cooling tower water inlet 16. The cooling tower 17 cools the heated hot water, and the cooled water flows out from the cooling tower water outlet 18 and finally flows back into the water storage tank 4 through the water tank water inlet 8 to start a new round of cycle.
[0054] When the liquid level sensor monitors that the water level of the water storage tank 4 is lower than 40%, the electromagnetic switch valve 2 opens, and the soft water generated by the soft water device 1 enters the water storage tank 4 through the water tank water replenishment port 3. Other devices in the system operate in the normal production state until the liquid level sensor monitors that the water level of the water storage tank 4 returns to above 40%.
[0055] When the liquid level sensor monitors that the water level of the water storage tank 4 is as low as below 25%, the water tank drain ball valve 6 and the cooling tower drain ball valve 21 are in the closed state. The water in the water storage tank 4 no longer flows out through the water tank drain port 5, and the water in the cooling tower 17 no longer flows out from the cooling tower drain port 20. At the same time, the two water pumps of the circulating water pump group 11 reduce the frequency or shut down one to reduce the flow rate of the water cycle until the liquid level sensor monitors that the water level of the water storage tank 4 returns to above 25%.
[0056] When the liquid level sensor detects that the water level in the water storage tank 4 is higher than 65%, the electromagnetic switch valve 2 is in the closed state, the water tank drain ball valve 6 and the cooling tower drain ball valve 21 are in the fully open state, and the two water pumps of the circulating water pump group 11 increase the frequency to increase the flow rate of the water circulation until the liquid level sensor detects that the water level in the water storage tank 4 returns below 65%.
[0057] When the liquid level sensor detects that the water level in the water storage tank 4 rises above 80%, the water tank drain ball valve 6 and the cooling tower drain ball valve 21 are in the fully open state, the water level in the cooling tower 17 rises and exceeds the height of the cooling tower full water port 19, and the excess water will overflow through the cooling tower full water port 19 and flow away. The circulating water pump group 11 further increases the frequency until the liquid level sensor detects that the water level in the water storage tank 4 returns below 80%.
[0058] In this solution, the frequency of the circulating water pump group 11 can be adjusted according to the temperature and pressure feedback by the resistance load box 14, making the system operate more safely and stably. And the working state of the entire cycle can be monitored and adjusted through a liquid level sensor, simplifying the configuration of the controller and saving costs. The signal feedback by the liquid level sensor will be used by the PLC to centrally control the electromagnetic switch valve 2 in the liquid cooling circulation water replenishing system. When the voltage of the electromagnetic switch valve 2 is 0V, the signal feedback requires it to be closed; when the voltage of the electromagnetic switch valve 2 is 24V, the signal feedback requires it to be opened. The automatic control of the entire cycle is realized, making the operation of the entire system more convenient.
[0059] In this solution, through the combined use of the electromagnetic switch valve 2, the circulating water pump group 11 and the check valve 12, and under the monitoring of the liquid level sensor and the cable, the change of the water level in the water storage tank 4 can be monitored accurately and in real time, and this information is fed back to the PLC. Then, the PLC automatically adjusts the working states of the electromagnetic switch valve 2, the circulating water pump group 11 and the check valve 12 components according to the received data, that is, timely opening or closing the electromagnetic switch valve 2, adjusting the frequency and working state of the circulating water pump group 11, and opening or closing the check valve 12 components to achieve precise control of the water flow. This centralized control and management greatly simplifies the operation process, reduces energy consumption at the same time, and improves the overall efficiency.
[0060] Embodiment 4:
[0061] The difference between Embodiment 4 and Embodiments 2 and 3 is only that in this embodiment, the size of the water storage tank 4 is 1.5 meters in length, 1 meter in width, and 1.5 meters in height, and the liquid level controller 7 is a liquid level gauge. As Figure 2 、 Figure 3 shown, an exhaust port 43 and a signal port 42 are provided at the top of the water storage tank 4, a water tank overflow port 41 is provided at the right position 0.1 meter away from the top of the water storage tank 4, and a liquid level gauge is provided inside the water storage tank 4.
[0062] Specifically, as Figure 2 shown, the length, width, and height of the water storage tank 4 are 1.5 meters, 1 meter, and 1.5 meters respectively. A water tank water replenishment port 3 is provided at a position 1 meter above the bottom on the left side of the water storage tank 4, a water tank sewage discharge port 5 is provided at the left bottom, a water tank water inlet 8 is provided at the top right, a water tank water outlet 9 is provided at a position 0.2 meters above the bottom on the right side, a water tank overflow port 41 is provided at a position 0.1 meters above the top of the water storage tank 4 on the right side and away from the water tank water inlet 8, and an exhaust port 43 is provided at a position on the top of the water storage tank 4 near the water tank water replenishment port 3 to balance the air pressure inside and outside the water storage tank 4 so that the water can flow out smoothly. A signal port 42 is provided at a position on the top of the water storage tank 4 near the water tank overflow port 41 for real-time monitoring of the water level change in the water storage tank 4; a liquid level gauge is arranged inside the water storage tank 4, and both ends of the liquid level gauge are connected to the water storage tank 4 through a G1 / 2 pipe clamp. As Figure 3 shown, the length of the water tank water replenishment port 3 is 0.1 meters, the distance between the water tank water replenishment port 3 and the inner side of the water storage tank 4 is 0.24 meters, and the lengths of the water tank water inlet 8, the water tank water outlet 9, and the water tank overflow port 41 are all 0.1 meters. The distance between the liquid level gauge and the right side of the water storage tank 4 is 0.4 meters. The overall size of the water storage tank 4 and the layout of various water tank interfaces ensure that the water volume in the entire circulating water replenishment system can be replenished in a timely manner on the premise of the smallest floor area, solve the problem of untimely water replenishment, and avoid the idling problem caused by water shortage. That is, the design of the water storage tank 4 can provide sufficient water storage capacity while minimizing the floor area. Through the settings of the water tank water replenishment port 3, the water tank water inlet 8, and the water tank water outlet 9, the water storage tank 4 can quickly replenish the water volume required by the circulating system, ensure that the system always has enough water for circulation, ensure that the water flows smoothly into the circulating pipeline, and ensure the stable operation of the system. The water tank overflow port 41 ensures that the water level in the water storage tank 4 will not be too high or too low, and there will be no water shortage / overflow situation, ensuring the stable operation of the liquid cooling cycle. Through these special designs, the water storage tank 4 not only provides sufficient water storage capacity, but also reaches an optimal balance point between the water replenishment volume and the circulation speed, thus avoiding the idling situation caused by water shortage. At the same time, this layout also reaches an optimal balance between the occupied space and the water flow speed.
[0063] In addition, the settings of the exhaust port 43, the signal port 42, and the position of the liquid level gauge together ensure that the water storage tank 4 can operate in a stable air pressure environment and can accurately monitor and control the liquid level. That is, through the exhaust port 43, the air pressure in the water storage tank 4 can be reduced, the air pressure inside and outside the water storage tank 4 can be balanced, and its pressure can be prevented from being too high, thus maintaining a stable air pressure environment; the signal port 42 can connect the liquid level gauge and other control devices to ensure the accuracy and reliability of signal transmission; the liquid level gauge is connected to the water storage tank 4 through a G1 / 2 pipe clamp, which can detect and measure the height or position of the liquid, while ensuring the accuracy of the liquid level data, and is connected to the PLC through the signal port 42 to realize real-time monitoring and feedback of the liquid level information, ensuring that the liquid levels of the water storage tank 4 and the cooling tower 17 always remain consistent. Such a design ensures that the water storage tank 4 can operate in a stable air pressure environment, enabling the liquid level gauge to accurately measure the actual liquid level height of the water storage tank 4, improving the accuracy of the liquid level data, and at the same time being able to always keep the liquid level of the water storage tank 4 consistent with that of the cooling tower 17, thereby balancing and stabilizing the entire liquid cooling circulation water replenishment system, so that there is always a certain amount of water stored in the circulation pipeline to avoid the situation of no water and solve the problem of timely water replenishment.
[0064] In summary, the special structural settings of the water storage tank 4 and the special settings of other tank interfaces enable the water storage tank 4 to minimize the occupied space while storing water. The design of the water storage tank 4 can ensure that there is enough water for replenishment in the entire circulation water replenishment system and solve the problem of timely water replenishment on the premise of the smallest floor area, thus avoiding the idling situation caused by water shortage. At the same time, the special positions of the exhaust port 43, the liquid level gauge, the signal port 42, and the tank overflow port 41 ensure that the water flow in the water storage tank 4 always remains in a relatively stable state, which not only prevents water flow blockage but also avoids water waste. In addition, the setting of the liquid level gauge can real-time monitor the liquid level height in the water storage tank 4 and ensure that it is consistent with the liquid level height of the upper cooling tower 17, thereby realizing a dynamic balance of the water inlet, water flow, and water outlet of the entire water storage tank 4. In addition, the geometric shape of the cuboid water tank is simple, the manufacturing process is relatively easy, and the installation and maintenance are also more convenient, reducing the long-term operation cost and complexity.
