[0027] A server is a device used to provide data processing. The server uses a Central Processing Unit (CPU) to process data. During operation, the server generates a large amount of heat, and correspondingly, heat dissipation of the server is required.

[0028] In related technologies, the heat dissipation efficiency of the server through a water-cooled cold plate is higher. During the long-term use of the water-cooled cold plate, the coolant inside also needs to be replenished and replaced, but currently, the process of replenishing and replacing the coolant in the water-cooled cold plate is complex.

[0029] In the liquid storage device proposed in this application, the liquid storage cavity of the liquid storage tank can be used to store coolant. External coolant can be transported to the liquid storage cavity through the liquid inlet pipeline, so that the coolant can be stored in the liquid storage tank. The moving component can drive the entire liquid storage device to move to a position close to the server that needs to be replenished with coolant. The liquid storage cavity can be connected to the cooling component of the server through the liquid discharge pipeline, so as to transport coolant into the cooling component of the server, achieving the purpose of replenishing coolant for the cooling component of the server. The moving component can make the liquid storage device approach different servers that need to be replenished with coolant. In this way, the liquid storage device of this application can replenish coolant for the cooling components of different servers, improving the applicability of the liquid storage device of this application. The detection component can detect the water quality of the coolant in the liquid storage cavity. When the water quality of the coolant in the liquid storage cavity does not meet the standard, the coolant in the liquid storage cavity can be discharged through the liquid discharge pipeline, and coolant can be re-transported into the liquid storage cavity through the liquid inlet pipeline to make the water quality of the coolant in the liquid storage cavity meet the standard. In this way, it is ensured that the water quality of the coolant transported to the cooling component of the server meets the standard, and the cooling component of the server can operate safely and stably.

[0030] In order to enable those skilled in the art of this technical field to better understand the solution of this application, the following further elaborates on this application in conjunction with the accompanying drawings and specific implementation manners.

[0031] See Figure 1 As shown, the embodiment of this application provides a liquid storage device for a server, including a liquid storage tank 100, a liquid inlet pipeline, a liquid discharge pipeline, a detection component 300, and a moving component 400. This liquid storage device can store coolant and transport the coolant to the cooling component of the server.

[0032] Among them, the liquid storage tank 100 is the basic component of the liquid storage device of this application. The liquid storage tank 100 can provide an installation foundation for at least some other components of the liquid storage device and serve the purpose of protecting at least some other components. The liquid storage tank 100 can be prepared from metal materials, making the liquid storage tank 100 have better structural strength, and thus making the durability and reliability of the liquid storage tank 100 better. Of course, at least part of the liquid storage tank 100 can also be prepared from polymer materials, so that the self-weight of the liquid storage tank 100 is relatively light and it has better corrosion resistance.

[0033] The liquid storage tank 100 has a liquid storage cavity 111. The liquid storage cavity 111 is an independent cavity structure inside the liquid storage tank 100 and can be used to store coolant. Specifically, part of the inner wall of the liquid storage cavity 111 of the liquid storage tank 100 can be prepared from polymer materials to prevent the inner wall of the liquid storage cavity 111 from being corroded and affecting the coolant.

[0034] The liquid inlet pipe is connected to the liquid storage cavity 111 in the liquid storage tank 100, and the liquid inlet pipe is configured to be able to transport the coolant into the liquid storage cavity 111. Specifically, one end of the liquid inlet pipe can be connected to the liquid storage cavity 111, and the other end of the liquid inlet pipe can be connected to an external device for storing the coolant. In this way, when the coolant in the liquid storage cavity 111 is insufficiently consumed, the external coolant can be transported into the liquid storage cavity 111 through the liquid inlet pipe to supplement the coolant in the liquid storage cavity 111.

[0035] The liquid discharge pipe is also connected to the liquid storage cavity 111. The liquid discharge pipe is configured to discharge the coolant in the liquid storage cavity 111, and the liquid discharge pipe is configured to be detachably connected to the cooling pipe of the server. Specifically, one end of the liquid discharge pipe can be connected to the liquid storage cavity 111. When it is necessary to transport the coolant in the liquid storage cavity 111 into the cooling component of the server, the other end of the liquid discharge pipe can be connected to the cooling component of the server, so that the coolant in the liquid storage cavity 111 can be transported into the cooling component of the server through the liquid discharge pipe to supplement the coolant in the cooling component of the server. Specifically, a quick connector 550 can be provided at one end of the liquid discharge pipe so that the liquid discharge pipe can be connected to the cooling component of the server.

[0036] The detection component 300 is arranged in the liquid storage tank 100. The detection component 300 is configured to be able to detect the water quality of the coolant in the liquid storage cavity 111 to determine whether the water quality of the coolant in the liquid storage cavity 111 meets the requirements. If the water quality of the coolant does not meet the requirements, it is easy to cause damage to the cooling component when the coolant is transported into the cooling component of the server. Therefore, when the detection component 300 detects that the water quality of the coolant in the liquid storage cavity 111 does not meet the requirements, the coolant in the liquid storage cavity 111 can be discharged through the liquid discharge pipe. Subsequently, the coolant can be replenished into the liquid storage cavity 111 of the liquid storage tank 100 again through the liquid inlet pipe until the water quality of the coolant in the liquid storage cavity 111 meets the requirements.

[0037] The moving component 400 is connected to the liquid storage tank 100. The moving component 400 is configured to be able to drive the liquid storage tank 100 to move, so that the liquid storage tank 100 can be moved to a specified position. Specifically, when it is necessary to supplement the coolant for the cooling component of a specified server through the liquid storage device of the present application, the liquid storage device can be moved to a position close to the cooling component of the specified server through the moving component 400, and then the liquid discharge pipe is connected to the cooling component. In this way, the connection structure between the liquid discharge pipe and the cooling component can be simplified, and the liquid discharge pipe can be more conveniently connected to the cooling component.

[0038] When the cooling components of other servers need to be replenished with coolant, the liquid storage device can be moved close to the cooling components of other servers through the moving component 400. The moving component 400 enables the liquid storage device to approach different servers whose cooling components need to be replenished with coolant. In this way, the liquid storage device of the present application can replenish coolant for the cooling components of different servers, improving the applicability of the liquid storage device of the present application.

[0039] In addition, when the coolant in the cooling component of the server needs to be replaced, the drain pipe can also be connected to the cooling component of the server, so that the coolant in the cooling component can be reversely transported to the drain pipe or the liquid storage cavity 111, and then the coolant can be discharged through the drain pipe.

[0040] Thus, the liquid storage device of the present application can not only transport coolant to the cooling components of different servers, but also detect the water quality of the coolant in the liquid storage cavity 111 to make the water quality of the coolant in the liquid storage cavity 111 meet the requirements. This makes the functions of the liquid storage device of the present application more complete and the integration degree higher.

[0041] In some embodiments, as shown in Figure 1 To enable the drain pipe to be connected to the liquid storage cavity 111 of the liquid storage tank 100, the liquid storage device of the present application may further include a first pipe 210 and a second pipe 220. The liquid storage tank 100 has a drain port, and the drain port is connected to the liquid storage cavity 111. One end of the first pipe 210 is connected to the drain port, so that the first pipe 210 can communicate with the liquid storage cavity 111. One end of the second pipe 220 is connected to the end of the first pipe 210 facing away from the drain port, and the other end of the second pipe 220 can be used to connect to the cooling component of the server or an external waste water collection device. The first pipe 210 and the second pipe 220 are connected to form a drain pipe. In this way, the coolant in the liquid storage cavity 111 can be sequentially transported to the cooling component of the server through the first pipe 210 and the second pipe 220, or when the water quality of the coolant in the liquid storage cavity 111 does not meet the requirements, the coolant in the liquid storage cavity 111 can be discharged through the first pipe 210 and the second pipe 220 in sequence.

[0042] The liquid storage device of the present application further includes a first switching valve 510. The first switching valve 510 is arranged between the first pipe 210 and the second pipe 220, and the first switching valve 510 is configured to control the on / off of the first pipe 210 and the second pipe 220. When the coolant in the liquid storage cavity 111 does not need to be discharged, the first pipe 210 and the second pipe 220 can be disconnected through the first switching valve 510 to prevent the coolant from flowing out of the liquid storage cavity 111. When the coolant in the liquid storage cavity 111 needs to be discharged, the first pipe 210 and the second pipe 220 can be connected through the first switching valve 510.

[0043] In some embodiments, referring to Figure 1 As shown, the liquid storage device of the present application further includes a driving pump 530. The driving pump 530 is disposed in the first pipeline 210 and is configured to drive the coolant to flow from the first pipeline 210 to the second pipeline 220. When it is necessary to deliver the coolant to the cooling component of the server or to discharge the coolant in the liquid storage cavity 111, the driving pump 530 can be used to drive the coolant to flow from the first pipeline 210 to the second pipeline 220. By providing the driving pump 530, the liquid storage device of the present application can actively deliver the coolant to the outside, making the efficiency of delivering the coolant to the outside higher.

[0044] In some embodiments, referring to Figure 1 As shown, in order to enable the liquid inlet pipeline to be connected to the liquid storage cavity 111 of the liquid storage tank 100, the liquid storage device of the present application may further be provided with a third pipeline 230 and a fourth pipeline 240. Among them, the liquid storage tank 100 has a liquid inlet, and the liquid inlet is connected to the liquid storage cavity 111. One end of the fourth pipeline 240 is connected to the liquid inlet, so that the fourth pipeline 240 can communicate with the liquid storage cavity 111. The other end of the fourth pipeline 240 can be connected to the first pipeline 210. One end of the third pipeline 230 can be connected to the first pipeline 210, and the other end of the third pipeline 230 can be connected to a device for storing coolant outside.

[0045] When the coolant in the liquid storage cavity 111 is insufficient, the other end of the third pipeline 230 can be connected to the device for storing coolant outside. The coolant in the device for storing coolant outside can be delivered to the first pipeline 210 through the third pipeline 230, then delivered to the fourth pipeline 240 through the first pipeline 210, and finally delivered to the liquid storage cavity 111 of the liquid storage tank 100 through the fourth pipeline 240, so that the coolant can be replenished into the liquid storage cavity 111. Therefore, the third pipeline 230, the first pipeline 210 and the fourth pipeline 240 can form a liquid inlet pipeline.

[0046] Since the driving pump 530 is disposed in the first pipeline 210, and the first pipeline 210 is connected to both the third pipeline 230 and the fourth pipeline 240, the driving pump 530 can drive the coolant to flow sequentially in the third pipeline 230, the first pipeline 210 and the fourth pipeline 240, so that the coolant can finally reach the liquid storage cavity 111.

[0047] Specifically, referring to Figure 1As shown, the first pipe 210 may be provided to include a first pipe section 211 and a second pipe section 212, wherein one end of the first pipe section 211 is connected to the liquid discharge port of the liquid storage tank 100, one end of the second pipe section 212 is connected to the end of the first pipe section 211 away from the liquid discharge port, and the second pipe 220 is connected to the end of the second pipe section 212 away from the first pipe section 211. The third pipe 230 is connected to a side of the second pipe section 212 adjacent to the first pipe section 211, and the fourth pipe 240 is connected to a side of the second pipe section 212 adjacent to the second pipe 220. In this way, the coolant in the third pipe 230 can be transported to the fourth pipe 240 after entering the second pipe section 212.

[0048] In addition, the first switch valve 510 is disposed between the second pipe section 212 and the second pipeline 220, so that the first switch valve 510 can control the connection and disconnection between the second pipe section 212 and the second pipeline 220. The first switch valve 510 is also disposed between the second pipe section 212 and the fourth pipeline 240, so that the first switch valve 510 can also control the connection and disconnection between the second pipe section 212 and the fourth pipeline 240. When the coolant in the liquid storage chamber 111 needs to be transported to the cooling component of the server, or the water quality of the coolant does not meet the standard and needs to be discharged, the second pipe section 212 can be connected to the second pipeline 220 through the first switch valve 510, and the fourth pipeline 240 can be disconnected from the second pipe section 212 through the first switch valve 510. In this way, the coolant can only be discharged through the second pipeline 220 after passing through the second pipe section 212.

[0049] When it is necessary to add coolant to the liquid storage chamber 111, the second pipe section 212 can be disconnected from the second pipe 220 through the first switch valve 510, and the fourth pipe 240 can be connected to the second pipe section 212 through the first switch valve 510. In this way, the coolant can only enter the liquid storage chamber 111 through the fourth pipe 240 after passing through the second pipe section 212.

[0050] The liquid storage device of the present application further includes a second switch valve 520, which is disposed between the third pipe 230 and the second pipe section 212, and is configured to control the connection and disconnection between the third pipe 230 and the second pipe section 212. The second switch valve 520 is also disposed between the first pipe section 211 and the second pipe section 212, and the second switch valve 520 can also control the connection and disconnection between the first pipe section 211 and the second pipe section 212.

[0051] When the coolant in the liquid storage chamber 111 needs to be transported to the cooling components of the server, or the water quality of the coolant does not meet the standard and needs to be discharged, the first pipe section 211 and the second pipe section 212 can be connected through the second switch valve 520, and the second pipe section 212 and the third pipe 230 can be disconnected through the second switch valve 520. In this way, the coolant can enter the second pipe section 212 after passing through the first pipe section 211, and be discharged through the second pipe 220, so as to prevent the coolant from flowing to the third pipe 230.

[0052] When it is necessary to add cooling liquid to the liquid storage chamber 111, the first pipe section 211 and the second pipe section 212 can be disconnected through the second switch valve 520, and the third pipe 230 can be connected to the second pipe section 212 through the second switch valve 520. In this way, the cooling liquid can be transported to the second pipe section 212 through the third pipe 230, and the cooling liquid can enter the liquid storage chamber 111 through the fourth pipe 240 after passing through the second pipe section 212. In this way, the cooling liquid can be prevented from flowing to the first pipe section 211, and the cooling liquid in the liquid storage chamber 111 can be prevented from being discharged from the second pipe 220.

[0053] The first switch valve 510 and the second switch valve 520 can control the connection and disconnection between multiple pipelines, between pipe sections, and between pipelines and pipe sections, which can simplify the pipeline structure of the liquid storage device of the present application and reduce the preparation cost of the liquid storage device.

[0054] In some embodiments, reference Figure 2 As shown, the first switch valve 510 in the present application can be an electric three-way valve, and the first switch valve 510 can be provided with a first opening 511, a second opening 512 and a third opening 513. The first opening 511, the second opening 512 and the third opening 513 of the first switch valve 510 can be connected to or disconnected from each other. Among them, the first opening 511 is connected to the end of the second pipe section 212 away from the first pipe section 211, the second opening 512 is connected to the second pipeline 220, and the third opening 513 is connected to the end of the fourth pipeline 240 away from the liquid inlet.

[0055] When the coolant in the liquid storage chamber 111 needs to be transported to the cooling components of the server, or the water quality of the coolant does not meet the standard and needs to be discharged, the first switch valve 510 can control the first opening 511 to be connected with the second opening 512, and the third opening 513 is closed, so that the second pipe section 212 can be connected with the second pipeline 220, and the fourth pipeline 240 is disconnected from the second pipe section 212. In this way, the coolant can only be discharged through the second pipeline 220 after passing through the second pipe section 212.

[0056] When it is necessary to replenish the coolant into the liquid storage cavity 111, the first switching valve 510 can control the first opening 511 to communicate with the third opening 513, and control the second opening 512 to be closed. Thus, the second pipe segment 212 can be disconnected from the second pipeline 220, and the fourth pipeline 240 can be communicated with the second pipe segment 212. In this way, the coolant can only enter the liquid storage cavity 111 through the fourth pipeline 240 after passing through the second pipe segment 212.

[0057] Reference Figure 3 As shown, in the present application, the second switching valve 520 can adopt an electric three-way valve, and the second switching valve 520 can be provided to include a fourth opening 521, a fifth opening 522 and a sixth opening 523. The fourth opening 521, the fifth opening 522 and the sixth opening 523 of the second switching valve 520 can communicate with each other or be disconnected. The fourth opening 521 is connected to one end of the first pipe segment 211 away from the liquid discharge port, the sixth opening 523 is connected to one end of the second pipe segment 212 away from the second pipeline 220, and the fifth opening 522 is connected to the third pipeline 230.

[0058] When the coolant in the liquid storage cavity 111 needs to be transported to the cooling component of the server, or when the water quality of the coolant does not meet the standard and needs to be discharged, the second switching valve 520 can control the fourth opening 521 to communicate with the sixth opening 523, and the fifth opening 522 is closed. Thus, the first pipe segment 211 can be communicated with the second pipe segment 212, and the third pipeline 230 can be disconnected from the second pipe segment 212. In this way, the coolant in the liquid storage cavity 111 can only enter the second pipe segment 212 and be discharged after passing through the first pipe segment 211, preventing the coolant from entering the third pipeline 230.

[0059] When it is necessary to replenish the coolant into the liquid storage cavity 111, the second switching valve 520 can control the fifth opening 522 to communicate with the sixth opening 523, and control the fourth opening 521 to be closed. Thus, the first pipe segment 211 can be disconnected from the second pipe segment 212, and the third pipeline 230 can be communicated with the second pipe segment 212. In this way, the coolant can be transported to the second pipe segment 212 through the third pipeline 230, and the coolant can enter the liquid storage cavity 111 through the fourth pipeline 240 after passing through the second pipe segment 212. Thus, the coolant can be prevented from flowing to the first pipe segment 211, and the coolant in the liquid storage cavity 111 can be prevented from being discharged through the first pipe segment 211.

[0060] In some embodiments, reference Figure 1 and Figure 4As shown, the liquid storage device of the present application may further include a control member 540 and a liquid level detection member 620. The control member 540 is electrically connected to the first switching valve 510 and the second switching valve 520. The control member 540 is also electrically connected to the detection assembly 300 and the liquid level detection member 620. The control member 540 can determine whether the quality of the coolant in the liquid storage chamber 111 meets the requirements according to the parameters of the quality of the coolant in the liquid storage chamber 111 detected by the detection assembly 300. The control member 540 can also determine whether it is necessary to supplement the coolant into the liquid storage chamber 111 according to the liquid level of the coolant in the liquid storage chamber 111 detected by the liquid level detection member 620.

[0061] When the coolant in the liquid storage chamber 111 needs to be transported to the cooling assembly of the server, or when the control member 540 determines that the quality of the coolant in the liquid storage chamber 111 does not meet the requirements, the control member 540 can control the first switching valve 510 to connect the first opening 511 with the second opening 512, and close the third opening 513, so that the second pipe section 212 can be connected to the second pipeline 220, and the fourth pipeline 240 can be disconnected from the second pipe section 212. In this way, the coolant can only be discharged through the second pipeline 220 after passing through the second pipe section 212.

[0062] The control member 540 can also control the second switching valve 520 to connect the fourth opening 521 with the sixth opening 523, and close the fifth opening 522, so that the first pipe section 211 can be connected to the second pipe section 212, and the third pipeline 230 can be disconnected from the second pipe section 212. In this way, the coolant in the liquid storage chamber 111 can only enter the second pipe section 212 and be discharged after passing through the first pipe section 211, preventing the coolant from entering the third pipeline 230.

[0063] When the control member 540 determines that the liquid level of the coolant in the liquid storage chamber 111 is too low and it is necessary to supplement the coolant into the liquid storage chamber 111 according to the liquid level information detected by the liquid level detection member 620 in the liquid storage chamber 111, the control member 540 can control the first switching valve 510 to connect the first opening 511 with the third opening 513, and close the second opening 512. Thus, the second pipe section 212 can be disconnected from the second pipeline 220, and the fourth pipeline 240 can be connected to the second pipe section 212. In this way, the coolant can only enter the liquid storage chamber 111 through the fourth pipeline 240 after passing through the second pipe section 212.

[0064] The control member 540 can also control the second switching valve 520 to communicate the fifth opening 522 with the sixth opening 523 and close the fourth opening 521. Thereby, the first pipe segment 211 can be disconnected from the second pipe segment 212, and the third pipe 230 can be communicated with the second pipe segment 212. In this way, the coolant can be transported into the second pipe segment 212 through the third pipe 230. After passing through the second pipe segment 212, the coolant can enter the liquid storage cavity 111 through the fourth pipe 240. Thereby, the flow of the coolant to the first pipe segment 211 can be prevented, and the coolant in the liquid storage cavity 111 can be prevented from being discharged through the first pipe segment 211.

[0065] In some embodiments, referring to Figure 1 and Figure 4 as shown, the detection component 300 of the present application can be provided with at least one of a turbidity detection member 310, a pH detection member 320, and a conductivity detection member 330. The turbidity detection member 310, the pH detection member 320, and the conductivity detection member 330 are electrically connected to the control member 540. Among them, the turbidity detection member 310 can detect the turbidity of the coolant in the liquid storage cavity 111. The pH detection member 320 can detect the pH of the coolant in the liquid storage cavity 111. The conductivity detection member 330 can detect the conductivity of the coolant in the liquid storage cavity 111.

[0066] The turbidity information of the coolant detected by the turbidity detection member 310 in the liquid storage cavity 111 can be transmitted to the control member 540. The control member 540 can determine whether the turbidity of the coolant in the liquid storage cavity 111 exceeds a preset turbidity. When the turbidity of the coolant in the liquid storage cavity 111 is greater than the preset turbidity, it indicates that the turbidity of the coolant is relatively high and the water quality of the coolant does not meet the requirements.

[0067] The pH information of the coolant detected by the pH detection member 320 in the liquid storage cavity 111 can be transmitted to the control member 540. The control member 540 can determine whether the pH of the coolant in the liquid storage cavity 111 is greater than a first preset pH or less than a second preset turbidity. When the pH of the coolant in the liquid storage cavity 111 is greater than the first preset pH or lower than the second preset pH, it indicates that the acidity or alkalinity of the coolant is too high and the water quality of the coolant does not meet the requirements.

[0068] The conductivity information of the coolant detected by the conductivity detection member 330 in the liquid storage cavity 111 can be transmitted to the control member 540. The control member 540 can determine whether the conductivity of the coolant in the liquid storage cavity 111 exceeds a preset conductivity. When the conductivity of the coolant in the liquid storage cavity 111 is greater than the preset conductivity, it indicates that the ion content of the coolant is too high, the conductivity is too high, and the water quality of the coolant does not meet the requirements.

[0069] When the detection component 300 includes a turbidity detection element 310, a pH detection element 320, and a conductivity detection element 330 at the same time, and the turbidity detection element 310 detects that the turbidity of the coolant in the liquid storage chamber 111 is greater than the preset turbidity, the pH detection element 320 detects that the pH of the coolant in the liquid storage chamber 111 is greater than the first preset pH or less than the second preset pH, or the conductivity detection element 330 detects that the conductivity of the coolant in the liquid storage chamber 111 is greater than the preset conductivity, the control member 540 controls the first switching valve 510 to communicate the first opening 511 with the second opening 512, and controls the fourth opening 521 to communicate with the sixth opening 523, so that the first pipe segment 211 is communicated with the second pipe segment 212, and the second pipe segment 212 is communicated with the second pipe 220. In this way, the coolant in the liquid storage chamber 111 can be discharged through the second pipe 220.

[0070] In some embodiments, referring to Figure 1 and Figure 4 as shown, the liquid storage device of the present application may further be provided with a pressure detection element 610. The pressure detection element 610 is arranged in the second pipe 220, and the pressure detection element 610 is electrically connected to the control member 540. The pressure detection element 610 can detect the pressure value in the second pipe 220 and transmit the pressure value in the second pipe 220 to the control member 540. When the liquid storage device of the present application conveys coolant to the cooling component of the server, the coolant flows from the first pipe 210 to the second pipe 220. When the coolant replenishment of the cooling component of the server is completed and the coolant cannot be continuously replenished into the cooling component, the coolant will accumulate in the second pipe 220, causing the hydraulic pressure in the second pipe 220 to increase. Correspondingly, the pressure value in the second pipe 220 detected by the pressure detection element 610 will increase. When the control member 540 determines that the pressure value in the second pipe 220 is greater than the preset pressure, it can be determined that the coolant cannot be continuously conveyed into the cooling component of the server. At this time, the control member 540 can control the second switching valve 520 to disconnect the fourth opening 521 from the sixth opening 523, and control the first switching valve 510 to disconnect the first opening 511 from the second opening 512, so as to prevent the coolant in the liquid storage chamber 111 from continuing to be discharged.

[0071] In some embodiments, referring to Figure 1 as shown, the liquid storage device of the present application may further be provided with a filter element 630. The filter element 630 is arranged in the second pipe segment 212. The filter element 630 can filter impurities in the coolant passing through the second pipe segment 212, so that the water quality of the coolant meets the requirements.

[0072] Specifically, the filter element 630 can be a Y-shaped filter. The filter screen inside the filter element 630 is set to filter impurities with a particle size greater than 5 μm in the coolant, so that the filter element 630 can filter the impurities in the coolant more fully, so that the quality of the coolant replenished into the liquid storage cavity 111 and the coolant transported to the cooling component of the server meets the requirements.

[0073] In addition, a filter membrane and an activated carbon filtration structure can also be provided inside the filter element 630, so as to further enhance the filtration performance of the filter element 630.

[0074] In some embodiments, referring to Figure 1 As shown, the liquid storage device of the present application can also be provided with a fifth pipeline 250. The fifth pipeline 250 is communicated with the liquid storage cavity 111 of the liquid storage tank 100, and the connection part of the fifth pipeline 250 and the liquid storage cavity 111 is located at the top of the liquid storage cavity 111. When the liquid level of the coolant in the liquid storage cavity 111 is too high, the coolant can be discharged out of the liquid storage cavity 111 through the fifth pipeline 250.

[0075] Specifically, when the liquid level detection element 620 fails, resulting in continuous delivery of coolant into the liquid storage cavity 111 and the liquid level of the coolant in the liquid storage cavity 111 being too high, the coolant can be discharged through the fifth pipeline 250 to prevent the driving pump 530 from being damaged, thus achieving the purpose of protecting the driving pump 530.

[0076] In some embodiments, referring to Figure 1 As shown, the liquid storage device of the present application can also be provided with a check valve 660. The check valve 660 can be arranged in the second pipe section 212. The check valve 660 is a passage in the direction from the second pipe section 212 to the second pipeline 220 or the fourth pipeline 240, and the check valve 660 is an open circuit in the direction from the second pipe section 212 to the first pipe section 211 and the third pipeline 230. This can prevent the coolant from flowing back, so that the coolant can be fully transported into the liquid storage cavity 111, or transported to the cooling component of the server, or discharged.

[0077] By arranging the check valve 660 in the second pipe section 212, it can be ensured that the coolant in the liquid storage device of the present application flows unidirectionally and does not flow back under various working conditions, reducing the number of check valves 660, simplifying the structure of the liquid storage device, and reducing the cost of the liquid storage device.

[0078] In some embodiments, referring to Figure 1As shown, the liquid storage device of the present application may further be provided with a sixth pipeline 260. The sixth pipeline 260 communicates with the liquid storage cavity 111 of the liquid storage tank 100, and the connection part of the sixth pipeline 260 and the liquid storage cavity 111 is located at the bottom of the liquid storage cavity 111. When the drain pipeline is blocked and the coolant in the liquid storage cavity 111 cannot be discharged out of the liquid storage cavity 111 through the drain pipeline, the sixth pipeline 260 can be communicated with the liquid storage cavity 111 so that the coolant in the liquid storage cavity 111 can be discharged through the sixth pipeline 260.

[0079] Specifically, a third switch valve 650 may be provided on the sixth pipeline 260, and the third switch valve 650 can control the on-off of the sixth pipeline 260. When the drain pipeline is operating normally, the third switch valve 650 can close the sixth pipeline 260, so that the coolant in the liquid storage cavity 111 can be normally discharged through the drain pipeline. When the drain pipeline fails, the third switch valve 650 can open the sixth pipeline 260, so that the coolant in the liquid storage cavity 111 can be discharged through the sixth pipeline 260. Thus, it is convenient for users to repair the drain pipeline.

[0080] In some embodiments, referring to Figure 1 As shown, the liquid storage device of the present application may further be provided with a breather valve 640. The breather valve 640 is arranged on the liquid storage tank 100 and communicates with the liquid storage cavity 111. By providing the breather valve 640, the air pressure in the liquid storage cavity 111 can be balanced with the external atmospheric pressure, so that the coolant in the liquid storage cavity 111 can be discharged through the drain pipeline and the coolant can be transported into the liquid storage cavity 111 through the liquid inlet pipeline.

[0081] In some embodiments, referring to Figure 1 As shown, the liquid storage device of the present application may further be provided with a flow meter 670 and a visual liquid level gauge 680. The flow meter 670 is arranged on the second pipe section 212, and the flow meter 670 can monitor the flow rate of the coolant passing through the second pipe section 212. The visual liquid level gauge 680 is arranged on the liquid storage tank 100, and the visual liquid level gauge 680 can facilitate users to observe the liquid level of the coolant in the liquid storage cavity 111.

[0082] In some embodiments, referring to Figure 5 As shown, the moving assembly 400 of the present application may be provided with a plurality of rollers 410. The plurality of rollers 410 can be arranged at the bottom of the liquid storage tank 100 so that the liquid storage tank 100 can be conveniently moved, and further the liquid storage device of the present application can be conveniently moved.

[0083] Specifically, the liquid storage tank 100 may be provided to include a housing 110 and an upper cover 120. The liquid storage cavity 111 is located inside the housing 110. The upper cover 120 is movably arranged on the housing 110 and can open and close the top end of the housing 110. Other components of the liquid storage device of the present application, including various detection components, can be arranged inside the housing 110. A plurality of pipes can be stored inside the housing 110, and the rollers 410 are arranged at the bottom of the housing 110, so as to facilitate the overall movement of the liquid storage device.
