[0004] The existing liquid replenishing devices have a single function. Most of them can only perform liquid replenishing operations in one of the manual liquid replenishing or automatic liquid replenishing methods, and the liquid replenishing method is not flexible enough. Moreover, the existing liquid replenishing devices do not take anti-overflow measures. When performing liquid replenishing operations on the liquid replenishing device, since the liquid replenishing device is mostly in the liquid-cooled cabinet and has a certain height from the ground, it is inconvenient for the operator to observe the liquid level of the liquid replenishing. During liquid replenishing, coolant overflow events often occur. Since there are many precision electronic devices in the data center, when the coolant overflows, it is extremely easy for the electronic components to malfunction, and the safe and stable operation of the data center cannot be guaranteed.

[0035] Please refer to Figure 1 and Figure 2 , the liquid replenishing device 10 provided by the embodiment of the present application can be used for the liquid-cooled cabinet 1, and includes a liquid storage tank 11, a manual liquid replenishing port 114 and an automatic liquid replenishing port 112 respectively provided at the top of the liquid storage tank 11. An overflow port 113 is provided at the upper part of the side wall of the liquid storage tank 11, and the overflow port 113 can be used to drain the liquid in the liquid storage tank 11 in time when the liquid level in the liquid storage tank 11 is too high. The manual liquid replenishing port 114 can be used to manually replenish the liquid storage tank 11; the automatic liquid replenishing port 112 can be used to connect to the automatic liquid replenishing component 14 to automatically replenish the liquid storage tank 11.
[0036] Specifically, in this embodiment, the liquid storage tank 11 can be a cylindrical tank body. A manual liquid filling port 114 and an automatic liquid filling port 112 are respectively provided on the top wall of the liquid storage tank 11. Among them, the diameter of the manual liquid filling port 114 is larger than that of the automatic liquid filling port 112. For example, the radial dimension of the manual liquid filling port 114 can be set to be not less than half of the inner diameter of the liquid storage tank 11. The advantage of this design is that the manual liquid filling port 114 can also be used as a cleaning port. The large-aperture manual liquid filling port 114 facilitates the operator to insert his hand or cleaning tools into the liquid storage tank 11 for cleaning. A baffle 111 can also be provided at the manual liquid filling port 114. The baffle 111 can be used to block the manual liquid filling port 114. The baffle 111 is hinged to the top wall of the liquid storage tank 11, or the baffle 111 is clamped to the manual liquid filling port 114 through a clamp. For example, when the liquid storage tank 11 does not need to be filled with liquid, the baffle 111 can be covered at the manual liquid filling port 114 to prevent dust, foreign objects, etc. from entering the liquid storage tank 11. The manual liquid filling port 114 can be used to manually fill the liquid storage tank 11. For example, one end of a tube can be inserted into the manual liquid filling port 114, and the other end is connected to a liquid supply device (not shown). By opening the liquid supply device, the liquid storage tank 11 can be filled with liquid through the tube.
[0037] The automatic liquid filling assembly 14 includes a first pump body 141 and a first filter 142 connected in series. The first pump body 141 is arranged close to the automatic liquid filling port 112. The liquid outlet of the first pump body 141 is connected to the automatic liquid filling port 112 through a pipeline, and the liquid inlet is connected to the liquid outlet of the first filter 142 through a pipeline. The liquid inlet of the first filter 142 can be used to connect to a liquid supply device. The first pump body 141 can be selected as a self-priming pump or a diaphragm pump. The advantage of selecting the above pump body is that at the initial stage of liquid filling, this pump body has a self-priming function and can actively absorb external liquid. When there is air at its suction port, it can still operate normally, avoiding the problem of dry burning of the pump body, thereby improving the reliability of the liquid filling device 10. The automatic liquid filling assembly 14 can be used to automatically supplement liquid to the liquid storage tank 11. The automatic liquid filling assembly 14 is always kept in communication with the liquid storage tank 11. By opening the first pump body 141 and the liquid supply device, the liquid storage tank 11 can be directly filled with liquid.
[0038] A maximum liquid level height limit value and a minimum liquid level height limit value are set for the liquid stored in the liquid storage tank 11. The maximum liquid level height limit value is set to prevent the liquid from overflowing when the liquid replenishment exceeds the maximum limit value. The minimum liquid level height limit value is set to prevent the liquid in the liquid storage tank 11 from being too little and to replenish the liquid storage tank 11 in time. Specifically, a liquid level tube 12 can be set. The liquid level tube 12 is a transparent tube and is arranged on the outer side wall of the liquid storage tank 11. The liquid level tube 12 is arranged vertically, and the upper and lower ends of the liquid level tube 12 are respectively communicated with the liquid storage tank 11. The height of the bottom end of the liquid level tube 12 is the above-mentioned minimum liquid level height limit value, and the height of the top end of the liquid level tube 12 is the above-mentioned maximum liquid level height limit value. The liquid level tube 12 can facilitate observing the liquid level height in the liquid storage tank 11.
[0039] A maximum liquid level height value can be set for the liquid stored in the liquid storage tank 11. The overflow port 113 is arranged at the upper part of the side wall of the liquid storage tank 11. The height of the lowest position of its liquid outlet can be set to be equal to or slightly higher than the maximum liquid level height limit value. In this way, when the liquid in the liquid storage tank 11 reaches or exceeds the maximum liquid level height limit value, it can be discharged out of the liquid storage tank 11 in time through the overflow port 113. The overflow port 113 can be realized in the form of a ball valve tower head, a ball valve pneumatic interface or a solenoid valve, which can ensure that the liquid in the liquid storage tank 11 is discharged in time when the liquid level reaches or exceeds the maximum liquid level height limit value. At the same time, it can also prevent the liquid and air in the liquid storage tank 11 from contacting and breeding bacteria to pollute the water quality. When a ball valve (ball valve tower head, ball valve pneumatic interface) is arranged at the overflow port 113, the valve is in the normally open state. When a solenoid valve is arranged at the overflow port 113, the solenoid valve is in the normally closed state. Only when the liquid level in the liquid storage tank 11 reaches or exceeds the maximum liquid level height limit value, the solenoid valve will open for drainage. To prevent the overflowing liquid from flowing to the outside and contacting other electronic components, a receiving device can be arranged below the overflow port 113. For example, a detachable receiving box (not shown) can be arranged below the overflow port 113. If the liquid replenishment device 10 is not provided with an automatic detection and control device, it can also be judged whether the liquid storage tank 11 is full by whether there is liquid flowing out at the overflow port 113, so as to solve the problem that the position of the liquid storage tank 11 is relatively high and it is not convenient to observe the internal liquid level. In this embodiment, an overflow pipe (not shown) is connected to the overflow port 113. The overflow pipe is used to discharge the liquid overflowing from the overflow port 113 to a preset location. For example, the liquid outlet end of the overflow pipe can be communicated with a sewage discharge device, or the overflow pipe can also be communicated with a liquid supply device to realize the reuse of the coolant, so as to reduce costs and avoid waste.
[0040] To further improve the safety and reliability of the liquid replenishing device 10, a safety valve pressure relief port 13 can also be provided at the top of the liquid storage tank 11. The safety valve pressure relief port 13 is used to automatically relieve the pressure of the cabinet system when the system pressure value of the liquid cooling cabinet is higher than the preset safety pressure value. The safety valve pressure relief port 13 is always in an open state. When the system pressure of the liquid cooling cabinet is too high, the safety valve pressure relief port 13 can relieve the pressure of the system and relieve the water volume to the liquid storage tank 11, avoiding frequent liquid replenishment of the liquid storage tank 11 and low liquid level alarm of the liquid storage tank 11 caused by pressure relief due to system pressure fluctuations.
[0041] An internal circulation component 15 is connected to the bottom of the liquid storage tank 11. The internal circulation component 15 includes a second filter 151, a second pump body 152 and a check valve 153 connected in series in sequence. The liquid inlet of the second filter 151 is connected to the liquid outlet at the bottom of the liquid storage tank 11. The internal circulation component 15 can be used to provide coolant for the liquid cooling system of the liquid cooling cabinet 1. The internal circulation component 15 is located below the bottom of the liquid storage tank 11, so that the liquid storage tank 11 has a certain potential energy difference for the second pump body 152, so that there is always liquid at the second pump body 152, avoiding dry burning of the second pump body 152 during initial operation. At the same time, a check valve 153 is provided at the liquid outlet end of the second pump body 152, so that the coolant can only flow from the liquid storage tank 11 to the liquid cooling system, that is, it is ensured that the liquid can only enter from the liquid inlet of the second pump body 152 and flow out from the liquid outlet of the second pump body 152, and the phenomenon of sucking the coolant in the liquid cooling system back into the second pump body 152 will not occur, ensuring the safe and reliable operation of the system.
[0042] A drain valve (not shown) can also be provided at the bottom of the liquid storage tank 11 to facilitate the discharge of the liquid in the liquid storage tank 11 and facilitate maintenance operations.
[0043] To further enhance the automation level of the liquid replenishing device 10 and ensure its safe and stable operation, a controller (not shown) and a liquid level detector (not shown) can also be provided. The liquid level detector is arranged in the liquid storage tank 11 and can be used to detect the liquid level height of the liquid stored in the liquid storage tank 11 and transmit it to the controller. The controller can be used to receive the liquid level information detected by the liquid level detector and control the start and stop of the automatic liquid replenishing component 14 according to the liquid level information. The liquid level detector can be, for example, a float type liquid level detector or other real-time liquid level detectors. A maximum liquid level height limit value and a minimum liquid level height limit value are set in the controller. During automatic liquid replenishment, if the real-time liquid level information detected by the liquid level detector is greater than or equal to the maximum liquid level height limit value, the controller controls the automatic liquid replenishing component 14 and / or the liquid supply device to stop working, so as to avoid continuously replenishing the coolant into the liquid storage tank 11 and causing the liquid to overflow; during manual liquid replenishment, if the real-time liquid level information detected by the liquid level detector is greater than or equal to the maximum liquid level height limit value, the controller controls the liquid supply device to stop working. If the real-time liquid level information detected by the liquid level detector is less than or equal to the minimum liquid level height limit value, the controller controls the liquid supply device (and the automatic liquid replenishing component 14) to start and automatically replenish the liquid into the liquid storage tank 11. During manual liquid replenishment, since there may be a situation where the pipe is not connected to the manual liquid replenishing port 114, that is, the pipe is pulled out of the liquid storage tank 11 and the baffle 111 is in a state of blocking the manual liquid replenishing port 114. At this time, an alarm device (not shown) can be provided. When the real-time liquid level information is less than or equal to the minimum liquid level height limit value, the controller controls the alarm device to give an alarm to prompt the operator to immediately replenish the liquid into the liquid storage tank 11.
[0044] As Figure 3 shown, an embodiment of the present application also provides a liquid-cooled cabinet 1, including the above-mentioned liquid replenishing device 10. The liquid replenishing device 10 is arranged in the middle area inside the liquid-cooled cabinet 1. The liquid-cooled cabinet 1 further includes a liquid cooling system (not shown). The liquid cooling system is used to directly contact with heat-generating components such as servers and perform heat exchange with them, so as to control their temperatures. The liquid replenishing device 10 is connected to the liquid cooling system through the internal circulation component 15 to replenish the coolant for the liquid cooling system.
[0045] The liquid replenishing device and the liquid-cooled cabinet provided by the embodiments of the present application make the liquid replenishing method more flexible and diverse by setting a manual liquid replenishing port and an automatic liquid replenishing port. The manual liquid replenishing port can simultaneously serve as a liquid replenishing port and a cleaning port, facilitating operations such as maintenance and cleaning of the liquid storage tank while realizing the liquid replenishing function; the automatic liquid replenishing port can automatically control the liquid replenishment according to the liquid level of the system, reducing manual operations and improving the liquid replenishing efficiency. At the same time, by setting components such as an overflow port, a safety valve pressure relief port, a liquid level pipe, and a drain valve, the safety and reliability of the liquid replenishing device and the liquid-cooled cabinet are enhanced, ensuring the safe and reliable operation of devices such as servers, and facilitating the maintenance of the liquid replenishing device.
