Description

Technical Field

[0001] The invention relates to the technical field of liquid cooling circulation, and in particular to a liquid cooling circulation water replenishment system. Background Art

[0002] The resistance load box is mainly used in the performance testing and aging of online high-power UPS, inverters, switching power supplies and diesel generator sets of power, telecommunications and other departments and manufacturers. When the resistance load box is running, it needs to be cooled by air cooling or liquid cooling. For large generator sets, in order to prevent the load box from overloading and burning, a liquid cooling cycle is generally used to dissipate heat from the load box. Among the common liquid cooling media, water is the most economical choice. The water temperature can be reduced faster through a cooling tower, thereby achieving more efficient liquid cooling.

[0003] The existing liquid cooling circulation system is directly connected to the water supply through the tap water pipe. During the water supply process, a water pump is installed on the tap water pipe to control the water supply amount. However, due to the delay and lag of the inverter adjustment of the water pump itself, the water supply amount will be adjusted untimely or excessively, which will cause the water level in the cooling tower to be too high or too low, making the water volume in the circulation pipeline too large or too small, thus affecting the cooling effect of the circulating water, and then making the resistance load box as the cooled object unable to effectively dissipate heat.

[0004] In view of this, it is necessary to develop a liquid cooling circulation water replenishment system with a stable water replenishment amount, so as to effectively make up for the shortcomings of the existing technology. Summary of the invention

[0005] The present invention aims to provide a liquid cooling circulating water replenishment system, which is used to solve the technical problem of poor cooling effect caused by untimely water replenishment in the existing system by optimizing the structure of circulating water replenishment.

[0006] To solve the above problems, the present invention adopts the following technical solutions: a liquid-cooled circulating water replenishment system, comprising a water tank, a cooling tower and an equipment resistance load box; the water tank is located below the cooling tower, and a softening device for softening tap water is connected between the water tank and the tap water pipe; a liquid level controller for monitoring the liquid level of the water tank is provided on the top of the water tank; a closed circulating water loop is formed between the water tank, the cooling tower and the resistance load box.

[0007] The principle and advantage of this scheme are: a closed circulating water loop is formed between the water tank, the cooling tower and the resistance load box. The water tank is used to store water and can replenish water in time to ensure that the resistance load box has enough water when needed and can dissipate heat in time. In other words, the water tank can provide a stable water source for the entire system to ensure the stable and continuous operation of the liquid cooling circulation water replenishment system. The cooling tower is used to cool the hot water from the resistance load box, and return it to the water tank after the temperature is reduced, so as to achieve recycling. The softening device is used to process municipal tap water, that is, to soften it to reduce impurities in the water and reduce dirt in pipes and equipment, thereby improving the operating efficiency and life of the system.

[0008] The water tank is located below the cooling tower. Through the special arrangement of the cooling tower and the water tank, the cooling water in the cooling tower will automatically flow into the water tank under the action of gravity, so that the liquid level of the water tank and the liquid level of the cooling tower can automatically remain consistent. A liquid level controller for monitoring the liquid level of the water tank is provided on the top of the water tank. When the liquid level of the water tank and the liquid level of the cooling tower are consistent, a liquid level sensor can be used to simultaneously detect the liquid level of the cooling tower and the liquid level of the water tank, and the liquid level change can be controlled by PLC, thereby 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.

When subjected to external pressure, it is not easy to deform due to the support of its four corners, ensuring the stability of the water tank. At the same time, the design of the wooden block effectively prevents the corrosion of the tank body caused by ground water, thereby extending the service life of the water tank.

[0015] Beneficial effects: The rational design of the cooling tower structure optimizes the water flow distribution and discharges the sediment, sludge and impurities at the bottom of the cooling tower, improving the quality of the water and thus the overall performance and reliability of the system.

[0016] Preferably, as an improvement, a load box water inlet is provided at the lower left of the resistance load box, and a load box water outlet is provided at the upper left.

[0017] Beneficial effect: The design of the water inlet and outlet of the load box allows 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 taken away.

[0018] Preferably, as an improvement, the liquid level controller is a liquid level sensor or a liquid level gauge, a cable is provided at the lower end of the liquid level sensor, the cable is directly hung into the water tank, and the water level height monitoring range of the liquid level sensor is 0 to 1.5 meters.

[0019] Beneficial effects: The water level changes of the entire water storage tank can be monitored in real time and accurately, and precise data can be provided.

[0020] Preferably, as an improvement, an electromagnetic switch valve is threadedly connected between the water softening device and the water storage tank, and the electromagnetic switch valve is controlled by a PLC signal.

[0021] Beneficial effect: The electromagnetic switch valve is automatically controlled by PLC signal control, which can realize the precise start and stop of water flow.

[0022] Preferably, as an improvement, the voltage of the electromagnetic switch valve is 24V / DC.

[0023] Beneficial effects: The 24V / DC voltage is stable and not easily affected by voltage fluctuations, ensuring that the solenoid switch valve can operate reliably. At the same time, its voltage power consumption is also small, which helps to reduce the overall energy consumption of the system.

[0024] Preferably, as an improvement, a filter, a circulating water pump group and a one-way valve are connected in sequence between the water outlet of the water tank and the water inlet of the load box.

[0025] Beneficial effects: The filter can further remove impurities, particulate matter, suspended matter and other pollutants in the soft water, and perform secondary treatment on the softened water to ensure that the water entering the resistance load box is clean and reduce failures caused by water quality problems; the circulating water pump group provides a stable water flow to ensure that water can be continuously transported from the water storage tank to the resistance load box; the one-way valve can prevent water from flowing back from the resistance load box to the water storage tank, avoiding water circulation chaos in the system, helping to maintain stable operation of the system and preventing pressure fluctuations and equipment damage caused by backflow.

[0026] Preferably, as an improvement, the circulating water pump group is composed of two parallel water pumps and four butterfly valves, and the outlet pipe of the circulating water pump group is welded to the one-way valve.

[0027] Beneficial effects: By controlling the working status and working frequency of the two water pumps, the total flow of the system can be flexibly adjusted to meet different needs. The butterfly valve can accurately control the flow of each water pump to ensure reasonable flow distribution of the system.

[0028] Beneficial effects of the invention: The invention provides a stable liquid cooling circulation water replenishment 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, it ensures that the water can be replenished continuously and stably, optimizes the space occupied by the system and can accurately control the flow rate, ensuring the efficient operation of the system, extending the service life of the system and reducing its energy loss.

[0029] The water tank adopts a square structure with a height of 1.5 meters, while the cooling tower is 2 meters high and located above the water tank. This layout not only optimizes the occupied space, but also uses gravity to provide sufficient water pressure to ensure that the system can stably and continuously supply water. In addition, the square structure is easy to install and maintain, and has good stability.

[0030] The dual treatment of municipal tap water includes softening treatment and filtration and sewage treatment. First, the municipal tap water is softened by a water softener to remove hard components such as calcium and magnesium ions in the water, thereby reducing the hardness of the water and reducing scaling in pipes and equipment. Then, the softened soft water is further filtered to remove residual impurities in the water, and the cooling tower sewage outlet and cooling tower sewage valve at the bottom of the cooling tower and the water tank sewage outlet and water tank sewage valve at the bottom of the water tank are used to regularly discharge sediments and impurities in the cooling tower and water tank to ensure clean water quality. This dual treatment method reduces system blockage, thereby improving the cooling efficiency of the system and extending the service life of the entire system.

[0031] The system can achieve precise control of water volume by using a combination of multiple control devices, ensuring that it can make corresponding adjustments according to different water level conditions, and replenish the water in the water tank in time to keep it in a normal state. That is, the electromagnetic switch valve, circulating water pump group and one-way valve are used in combination to achieve different water level adjustments. The electromagnetic switch valve automatically controls the inlet and outlet of soft water in the soft water device through PLC signals to achieve precise control of water in the soft water device. The circulating water pump group controls the water circulation flow by reducing the pump frequency or switch state. The one-way valve not only controls the amount of water flowing to the resistance load box, but also prevents water from flowing back from the resistance load box to the water tank, avoiding water circulation chaos. The synergy of these control devices not only improves the response accuracy of the system, but also reduces energy loss and extends the service life of the system.

[0032] In summary, the present invention ensures that the system can continuously and stably circulate water to meet various cooling needs by optimizing the spatial layout of the water storage tank and the cooling tower. Through dual treatment - softening treatment and filtration and sewage treatment, the water quality in the system is significantly improved, the accumulation of impurities and dirt is reduced, 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 the electromagnetic switch valve, the circulating water pump group and the one-way valve, the precise control of the water volume is achieved, further improving the cooling effect of the system and reducing energy loss.

[0038] Embodiment 1:

[0039] The embodiment is basically as follows Figure 1 As shown, a liquid cooling circulation water replenishment system includes: a softening 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 of the water softener 1 is connected to the municipal tap water, and the water outlet is connected to the electromagnetic switch valve 2; the water tank water replenishment port 3 is connected to the outlet pipe 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 pipe, the water tank water outlet 9 is connected to the inlet of the circulating water pump group 11 through a flange and a pipe, the cooling tower 17 is placed above the water storage tank 4, the cooling tower water inlet 16 is connected to the load box water outlet 15 through a flange and a pipe; the outlet pipe 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 loop.

[0041] Specifically, the water inlet of the water softening device 1 is connected to the 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 of the water softening device 1 is provided with an electromagnetic switch valve 2. The inlet pipe of the water softening device 1 and the electromagnetic switch valve 2 are connected by threads, 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 tank 4, that is, the outlet pipe of the electromagnetic switch valve 2 is connected to the water tank water supply port 3 by flange. The water tank water inlet 8 is connected to the cooling tower water outlet 18 by flange and pipeline. The cooling tower 17 is placed above the water tank 4, and the bottom of the cooling tower 17 is higher than the top of the water tank 4, so that the water in the cooling tower 17 can flow to the water tank 4 naturally by gravity, reducing unnecessary power loss. The water tank outlet 9 is connected to the inlet of the circulating water pump group 11 by flange and pipeline. A filter 10 is provided between the water tank outlet 9 and the circulating water pump group 11. The inlet and outlet pipes of the filter 10 are connected by flange. The filter 10 is used to further remove impurities in the municipal tap water. A liquid level controller 7 is provided on the top of the water tank 4 to monitor the water level; a water tank sewage ball valve 6 connected by flange and pipeline is installed on the left side of the water tank sewage outlet 5, and a water tank is connected to the left side of the water tank sewage ball valve 6.

[0043] The cooling tower water inlet 16 is connected to the load box water outlet 15 through flanges and pipes, the cooling tower sewage outlet 20 is connected to the cooling tower sewage ball valve 21 through flanges and pipes, and the left side of the cooling tower sewage ball valve 21 is connected to the water pool;

[0044] The outlet pipe on the right side of the circulating water pump group 11 is connected to the water inlet 13 of the load box through a flange, and a one-way valve 12 is provided between the circulating water pump group 11 and the water inlet 13 of the load box. The inlet and outlet pipes of the one-way valve 12 are connected by welding. In this embodiment, the circulating water pump group 11 is composed of two parallel water pumps and four butterfly valves. In this embodiment, the water in the pool can flow to the soft water device 1 to replenish the system.

[0045] The liquid cooling circulation water replenishment system adopted in this scheme optimizes the structure and position of the water tank 4 and the cooling tower 17, ensuring that there is always enough water in the system to replenish it in time, so that the system can continuously and stably carry out circulation water replenishment to meet various cooling needs, ensuring that there is always enough water in the system to replenish it in time, thereby ensuring 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 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 of the entire system, making the layout more compact. In addition, compared with the traditional liquid cooling cycle, the waste of water resources can be greatly reduced, that is, the water discharged from the water tank drain outlet 5 and the cooling tower drain outlet 20 in this scheme will be discharged into the pool and left to stand. After being softened by the water softening device 1, it can be recycled again, reducing the amount of tap water. By softening municipal tap water through the water softening device 1 and through the sewage outlet, sewage ball valve, and filter 10, the dirt that blocks the pipes in the water circulation can be effectively reduced, and the water flow loss can be reduced 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. In addition to controlling whether to discharge sewage, the water tank sewage ball valve 6 and the cooling tower sewage ball valve 21 can also control the change of the water level. When the water level in the water storage tank 4 and the cooling tower 17 is not within the normal range, the water level change can be controlled by adjusting the opening size of the water tank sewage ball valve 6 and the cooling tower sewage ball valve 21, thereby enhancing the control of the water level.

[0046] Embodiment 2:

[0047] The difference between the second embodiment and the first embodiment is that the structure of the water tank 4 is a square structure and the height of the water tank 4 is 1.5 meters. The four vertical sides and the horizontal bottom surface can evenly distribute the pressure, ensuring the uniform pressure in the water tank 4, so that the feedback data of the liquid level controller 7 is 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 filling port 3 is provided on the left side of the water tank 4 at a distance of 1 meter from the bottom. When the water tank filling port 3 is filled with water from above, the disturbance to the existing water in the water 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 the sediment; a water tank sewage outlet 5 is provided at the bottom of the left side, which can effectively discharge the sediment, sludge and impurities accumulated at the bottom of the water tank 4; a water tank water inlet 8 is provided at the top of the right side of the water tank 4, which reduces the disturbance to the existing water in the water tank 4 and maintains the stability of the water; a water tank outlet 9 is provided on the right side of the water tank 4 at a distance of 0.2 meters from the bottom. When discharging water, gravity can be used to drain the water, which reduces the pumping demand and saves energy. At the same time, it ensures that the water level in the water tank 4 drops steadily to avoid drastic changes in the water level caused by rapid drainage. A cooling tower full water inlet 19 is provided at the left side of the cooling tower 17, 1.5 meters away from the bottom of the cooling tower 17, to ensure that the water level in the cooling tower 17 is not too high, and the excess water will flow out through the cooling tower full water inlet 19, thereby preventing water overflow. A cooling tower sewage outlet 20 is provided at the bottom of the left side, a cooling tower water inlet 16 is provided at the right side of the cooling tower 17, 0.5 meters away from the bottom of the cooling tower 17, and a cooling tower water outlet 18 is provided at the right side, 0.2 meters away from the bottom of the cooling tower 17, which is similar to the structural design of the water storage tank 4. The arrangement of the water storage tank 4 and the cooling tower 17 structure optimizes the distribution of the water flow, enables continuous and stable water replenishment, and improves the overall performance and reliability of the system.

[0049] In addition, wooden blocks are provided on both sides of the bottom of the water tank 4 to raise the water tank 4, so as to prevent water accumulation on the ground from corroding the water tank 4, reduce the risk of corrosion, and extend the service life of the water tank 4. The cooling tower 17 is placed above the water tank 4 and connected with pipes. At the same time, the bottom of the cooling tower 17 is higher than the top of the water tank 4, so that the water in the cooling tower 17 can flow to the water tank 4 naturally by gravity, so that the liquid level of the water tank 4 and the liquid level of the cooling tower 17 are consistent, reducing unnecessary energy loss, and ensuring that the water tank 4 always has enough water and can be replenished in time, thereby improving the cooling efficiency.

[0050] The special structure and position of the water tank 4 in this solution not only ensures sufficient water for technical replenishment, but also reduces the space occupied by the system, while reducing unnecessary power losses, ensuring the stability and reliability of the system and improving the cooling effect.

[0051] Embodiment three:

[0052] The difference between the third embodiment and the first embodiment is that Figure 1As shown, the liquid level controller 7 used in this embodiment is a liquid level sensor. The top of the water tank 4 is provided with an air outlet 43 that can be opened and closed, and an M20×1.5 internal threaded joint for connecting the liquid level sensor. The cable of the liquid level sensor is directly suspended in the water tank 4 for monitoring the water level. The water level height monitoring range of the liquid level sensor is 0 to 1.5 meters. The liquid level sensor can monitor the water level changes of the entire water tank 4 in real time and accurately, and timely adjust the water level of the water tank 4 and the cooling tower 17, 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, ensuring the efficient and stable operation of the liquid cooling cycle, so that the resistance load box 14 will not have untimely heat dissipation. In this embodiment, the normal water level is set to 0.6 to 0.9 meters. If it 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 level of the water tank 4 and the cooling tower 17 is about 50%, at this time the electromagnetic switch valve 2 is in a closed state, the soft water produced by the water softening device 1 will not enter through the water tank water replenishment port 3, the two water pumps of the circulating water pump group 11 work at a normal frequency, the water tank sewage ball valve 6 and the cooling tower sewage ball valve 21 are in a half-open state, the water in the water tank sewage outlet 520 and the cooling tower sewage outlet 20 will flow into the pool, and will be recycled through the water softening device 1; The water in the water storage tank 4 flows out from the water tank outlet 9, flows through the filter 10, the circulating water pump group 11 and the one-way 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 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 circulation.

[0054] When the liquid level sensor detects that the water level in the water tank 4 is lower than 40%, the electromagnetic switch valve 2 opens, and the soft water produced by the softening device 1 enters the water tank 4 through the water tank water replenishment port 3. Other devices in the system operate in normal production status until the liquid level sensor detects that the water level in the water tank 4 recovers to above 40%.

[0055] When the liquid level sensor detects that the water level of the water tank 4 is below 25%, the water tank drain ball valve 6 and the cooling tower drain ball valve 21 are in a closed state, the water in the water 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 of them to reduce the flow rate of the water circulation, until the liquid level sensor detects that the water level of the water tank 4 recovers to above 25%.

[0056] When the liquid level sensor detects that the water level in the water tank 4 is higher than 65%, the electromagnetic switch valve 2 is in a closed state, the water tank drain ball valve 6 and the cooling tower drain ball valve 21 are in a 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 tank 4 returns to below 65%.

[0057] When the liquid level sensor detects that the water level in the water tank 4 rises to more than 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 and flow away through the cooling tower full water port 19, and the circulating water pump group 11 will further increase the frequency until the liquid level sensor detects that the water level in the water tank 4 returns to 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 from the resistance load box 14, so that the system can operate more safely and stably. And the working state of the entire cycle can be monitored and adjusted through a liquid level sensor, which simplifies the configuration of the controller and saves costs. Through the signal fed back by the liquid level sensor, the electromagnetic switch valve 2 in the liquid cooling circulation water replenishment system will be centrally controlled by the PLC. When the voltage of the electromagnetic switch valve 2 is 0V, the signal feedback needs to be closed; when the voltage of the electromagnetic switch valve 2 is 24V, the signal feedback needs to be turned on. Automatic control of the entire cycle is achieved, making the operation of the entire system more convenient.

[0059] In this solution, by combining the electromagnetic switch valve 2, the circulating water pump group 11 and the one-way valve 12, and monitoring by the liquid level sensor and the cable, the water level changes in the water tank 4 can be accurately monitored in real time, and this information can be fed back to the PLC, which then automatically adjusts the working state of the electromagnetic switch valve 2, the circulating water pump group 11 and the one-way 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 one-way valve 12 component, so as to achieve precise control of the water flow. This centralized control management greatly simplifies the operation process, while also reducing energy consumption and improving overall efficiency.

[0060] Embodiment 4:

[0061] The only difference between the fourth embodiment and the second and third embodiments is that the dimensions of the water tank 4 in this embodiment are 1.5 meters long, 1 meter wide and 1.5 meters high, and the liquid level controller 7 is a liquid level meter. Figure 2 , Figure 3 As shown, an exhaust port 43 and a signal port 42 are provided at the top of the water tank 4, a water tank overflow port 41 is provided at the right position 0.1 meters away from the top of the water tank 4, and a liquid level meter is provided inside the water tank 4.

[0062] Specifically, Figure 2 As shown, the length, width and height of the water tank 4 are 1.5 meters, 1 meter and 1.5 meters respectively. A water tank filling port 3 is provided on the left side of the water tank 4 at a distance of 1 meter from the bottom, a water tank sewage outlet 5 is provided on the left bottom, a water tank water inlet 8 is provided on the right top, a water tank water outlet 9 is provided on the right side at a distance of 0.2 meters from the bottom, a water tank overflow port 41 is provided on the right side 0.1 meters away from the top of the water tank 4 and away from the water tank water inlet 8, an exhaust port 43 is provided on the top of the water tank 4 near the water tank filling port 3 to balance the air pressure inside and outside the water tank 4 so that the water can flow out smoothly, a signal port 42 is provided on the top of the water tank 4 near the water tank overflow port 41 to monitor the water level changes in the water tank 4 in real time; a liquid level gauge is provided inside the water tank 4, and both ends of the liquid level gauge are connected to the water tank 4 through G1 / 2 pipe clamps. Figure 3 As 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, and the distance between the liquid level meter 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 time under the premise of minimum floor space, solve the problem of untimely water replenishment, and avoid the idling problem caused by lack of water. That is, the design of the water storage tank 4 can provide sufficient water storage while minimizing the floor space. Through the arrangement 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 circulation system, ensure that the system always has enough water for circulation, ensure that the water flow enters the circulation pipeline smoothly, and ensure the stable operation of the system. The water tank overflow port 41 prevents the water level of the water tank 4 from being too high or too low, and prevents water shortage / overflow, thereby ensuring the stable operation of the liquid cooling cycle. Through these special designs, the water tank 4 not only provides sufficient water storage, but also achieves an optimal balance between the water replenishment amount and the circulation speed, thereby avoiding idling due to water shortage. At the same time, this layout also achieves an optimal balance between the occupied space and the water flow speed.

[0063] In addition, the setting of the exhaust port 43, the signal port 42 and the position of the liquid level meter together ensure that the water tank 4 can operate in a stable air pressure environment and can accurately monitor and control the liquid level. That is, the air pressure in the water tank 4 can be reduced through the exhaust port 43, and the air pressure inside and outside the water tank 4 can be balanced to prevent the pressure from being too high, thereby maintaining a stable air pressure environment; the signal port 42 can be connected to the liquid level meter and other control equipment to ensure the accuracy and reliability of signal transmission; the liquid level meter is connected to the water 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 achieve real-time monitoring and feedback of liquid level information, ensuring that the liquid levels of the water tank 4 and the cooling tower 17 are always consistent. Such a design ensures that the water tank 4 can operate in a stable air pressure environment, so that the liquid level meter can accurately test the actual liquid level height of the water tank 4, thereby improving the accuracy of the liquid level data. At the same time, it can always keep the liquid level of the water tank 4 consistent with the liquid level of the cooling tower 17, thereby balancing and stabilizing the entire liquid cooling circulation water replenishment system, so that a certain amount of water is always stored in the circulation pipeline to avoid the situation of no water, thus solving the problem of timely water replenishment.

[0064] In summary, the special structural setting of the water tank 4 and the special setting of other water tank interfaces enable the water tank 4 to store water while minimizing the occupied space. The design of the water tank 4 can ensure that there is enough water to replenish the entire circulating water replenishment system and solve the problem of timely water replenishment under the premise of occupying the smallest area, thereby avoiding idling due to lack of water. At the same time, the special position setting of the exhaust port 43, the liquid level meter, the signal port 42 and the water tank overflow port 41 ensures that the water flow in the water tank 4 is always kept in a relatively stable state, which not only prevents water flow blockage, but also avoids water waste. The setting of the liquid level meter can monitor the liquid level in the water tank 4 in real time and ensure that it is consistent with the liquid level of the cooling tower 17 above, thereby achieving a dynamic balance of water inlet, water flow and water outlet of the entire water tank 4. In addition, the rectangular water tank has a simple geometric shape, a relatively easy manufacturing process, and is relatively convenient to install and maintain, reducing the cost and complexity of long-term operation.
