The liquid cooling technology is more complex than the air cooling technology, and more relevant supporting devices are needed, one of which is a water storage tank. The main function of the water storage tank is to provide clean water in real time to the secondary side ring network, so the water storage capacity and other indicators of the water storage tank need to be monitored.

[0023] The specific embodiments of the present application will be described in detail below with reference to the drawings, but it should be understood that the protection scope of the present application is not limited by the specific embodiments.

[0024] Unless otherwise explicitly indicated, in the entire specification and claims, the term "comprise" or its variants such as "include" or "comprise" and the like will be understood to include the stated element or component, but not exclude other elements or components.

[0025] As shown in Figs. 1-2 , a water storage tank convenient for checking internal liquid level according to an embodiment of the present application is mainly used for water replenishment of a liquid cooling data center secondary side ring network.

[0026] The water storage tank comprises a tank body 1, the top of the tank body 1 is provided with a water inlet 101, the bottom is provided with a water outlet 102, and the side of the top is provided with an overflow 103. The water outlet 102 and the overflow 103 are arranged on the same side of the tank body 1; the ultrapure water flows into the water storage tank through the water inlet 101, the water outlet 102 sends the ultrapure water to the inside of the ring network through a water pump, and the overflow 103 controls the water level and prevents the water from overflowing out of the tank body 1.

[0027] The water pump on the water outlet 102 can be controlled by the monitoring platform to control the flow of the ultrapure water into the inside of the ring network.

[0028] The tank body 1 is also provided with a liquid level scale 2 and a pressure sensor 3. The liquid level scale 2 is arranged outside the side wall of the tank body 1, and the upper part and the lower part thereof are respectively connected with the inside of the tank body 1. The liquid level scale 2 is provided with a float, the outer surface is made of transparent material and is provided with a scale thereon, according to the principle of the communicating vessel, the water level in the liquid level scale 2 is the same as that in the tank body 1, the float can float on the liquid level surface in the liquid level scale 2, when the liquid level rises or falls, the float moves accordingly, and the displacement of the float is converted into an indication through the scale on the liquid level scale 2.

[0029] The pressure sensor 3 is arranged at the bottom inside the tank body 1, and the pressure sensor 3 further comprises a matched data collector 4 and a data processor 5. The pressure sensor 3 is used for collecting liquid level pressure data; the data collector 4 is used for sending the liquid level pressure data collected by the pressure sensor 3 to the data processor 5, and sending the data processed by the data processor 5 to the monitoring platform; and the data processor 5 is used for converting the liquid level pressure data into a water storage capacity value.

[0030] Specifically, the pressure sensor 3 sends the detected liquid level pressure data to the data processor 5 through the data collector 4, the data processor 5 converts the liquid level pressure data into a water storage capacity value, and then the data collector 4 sends the water storage capacity data to the monitoring platform, the monitoring platform performs real-time monitoring, display, and sets a liquid level alarm value, and prompts the operation and maintenance personnel to check the water tank water quantity on site when the set threshold value is higher or lower, can detect the water tank liquid level capacity situation online for 24 hours, and solves the pain point of checking the water storage tank capacity of the data center through the combination of manual and automatic detection.

[0031] The working principle of the liquid level scale 2 is based on the principle of the communicating vessel, that is, when the bottoms of two open containers are connected, their liquid surfaces will maintain the same level. In the liquid level scale 2, the glass tube is connected with the container or pipeline system, so the liquid level in the glass tube will be consistent with that in the container or pipeline. By observing the change of the liquid level in the glass tube, the liquid level in the container or pipeline can be directly understood. The glass liquid level scale mainly comprises a glass tube body, a connecting flange, a liquid level indicator and the like.

[0032] The pressure sensor 3 mainly realizes the conversion of the pressure signal into the liquid level height through the static pressure measurement principle: when the pressure sensor is installed at the bottom of the container, as the liquid level changes, the liquid pressure on the sensor will also change accordingly. There is a direct relationship between this pressure change and the liquid level height, that is, the higher the liquid level, the greater the pressure on the sensor; on the contrary, the lower the liquid level, the smaller the pressure. The pressure sensor 3 perceives the pressure exerted by the liquid on its sensitive element (pressure-sensitive resistor), causing corresponding physical quantity changes (resistance value changes) inside the sensor. The circuit or processing unit inside the sensor converts these physical quantity changes into electrical signals (voltage, current, etc.), and the size of the electrical signal is proportional to the liquid pressure, thus indirectly reflecting the height of the liquid level. The electrical signal is further processed by the digital processor, such as amplification, filtering, linearization, etc., to improve the measurement accuracy and stability. According to the parameters such as the density of the liquid and the acceleration of gravity, the height of the liquid level can be calculated from the pressure value, and the water storage capacity can be converted from the liquid level height and the area of the water tank.

[0033] In addition, a colored light strip 6 can be provided around the transparent outer surface of the liquid level scale 2, which is connected to the data processor 5 and can display different colors according to the water storage capacity value converted by the data processor 5. For example, when the water storage capacity value is 0-30% of the total storage capacity, it is displayed in blue, indicating a low liquid level; when the water storage capacity value is 30%-70% of the total storage capacity, it is displayed in green, indicating a normal liquid level range; when the water storage capacity value is 70% of the total storage capacity, it is displayed in yellow, serving as a warning.

[0034] The brightness of the light can be adjusted according to the ambient light to ensure that it can be clearly seen under various lighting conditions, making it easy for the operator to quickly judge the liquid level state from a distance, and when approaching, to judge whether there is a difference between the display of the liquid level scale 2 and the pressure sensor 3, and then to detect and maintain.

[0035] The utility model discloses a liquid level scale and a pressure sensor are installed outside and inside the water tank respectively to monitor the water storage capacity in the water tank in real time, solve the problem that the existing water tank needs to open the water tank cover to observe the liquid level, the water tank is mainly used for the water replenishment of the liquid cooling data center secondary side ring network, and the liquid level is displayed in real time by installing the liquid level meter outside the water tank, which is convenient for observation. The sensor is arranged inside the water tank to detect the water tank pressure, the water capacity in the water tank is converted according to the pressure value, the data is transmitted to the monitoring platform for real-time monitoring and display, and the liquid level alarm value is set, which prompts the operation and maintenance personnel to check the water tank water condition on site when the set threshold is higher or lower.
