Description

Technical Field

[0001] This application relates to the field of fluid replenishment equipment technology, and more particularly to an automatic fluid supply and recovery device. Background Technology

[0002] A server is a type of computer that provides computing or application services to other client machines (such as PCs, smartphones, ATMs, and even large equipment like train systems) on a network. With the rapid development of information and data technologies and their applications, traditional air cooling systems are no longer sufficient to meet the demands.

[0003] Liquid cooling systems, by directly introducing coolant into the server's interior, can significantly improve the efficiency of heat absorption and removal, ensuring stable equipment operation. Market demand for liquid cooling systems is growing daily. However, traditional liquid cooling systems generally employ manual replenishment and recovery methods, which are not only inefficient but also prone to errors, failing to meet the needs of modern industrial production. Utility Model Content

[0004] In view of this, it is necessary to provide an automatic liquid supply and recovery device to improve the technical problems of cumbersome manual liquid replenishment operation and low liquid replenishment efficiency.

[0005] One embodiment of this application provides an automatic liquid supply and recovery device. The automatic liquid supply and recovery device includes a liquid replenishment and return assembly, a liquid recovery assembly, and a gas supply assembly. The liquid replenishment and return assembly includes a first liquid storage tank, a liquid replenishment pipeline, and a filling pipeline. The liquid replenishment pipeline is configured to connect the first liquid storage tank and an external liquid source, allowing liquid from the external liquid source to flow into the first liquid storage tank along the liquid replenishment pipeline. The filling pipeline is configured to connect the first liquid storage tank and the inlet of a liquid-cooled pipe in an external device, allowing liquid in the first liquid storage tank to flow into the liquid-cooled pipe along the filling pipeline. The liquid recovery assembly includes a second liquid storage tank and an inlet pipeline. The inlet pipeline is configured to connect the second liquid storage tank and the outlet of the liquid-cooled pipe, allowing liquid in the liquid-cooled pipe to flow into the second liquid storage tank along the inlet pipeline. The air supply assembly includes an air compressor and an intake pipe. The intake pipe is configured to connect the air compressor and the inlet of the liquid cooling pipe. External air can be compressed by the air compressor and flow into the liquid cooling pipe along the intake pipe to discharge the liquid in the liquid cooling pipe.

[0006] The aforementioned automatic liquid supply and recovery equipment, through the cooperation of the liquid replenishment and return component, the liquid recovery component, and the air supply component, can realize automatic liquid replenishment and liquid drainage recovery for external equipment. This not only helps to improve the liquid replenishment efficiency and accuracy, making it suitable for efficient automated production lines, but also helps to reduce the labor intensity of workers.

[0007] In some embodiments of this application, the liquid replenishment and reflux assembly further includes a reflux line configured to connect the first liquid storage tank and the outlet of the liquid cooling pipe, so that excess liquid in the liquid cooling pipe can flow back to the first liquid storage tank through the reflux line.

[0008] By setting up a return pipeline, it is possible to recirculate and replenish liquid to external equipment. This improves the completeness of liquid replenishment to external equipment, reducing the risk of incomplete replenishment in automatic liquid supply and recovery equipment. Furthermore, it facilitates the recycling of liquid, reducing waste and lowering production costs.

[0009] In some embodiments of this application, the automatic liquid supply and recovery device further includes a first flow meter, a second flow meter, and a third flow meter. The first flow meter is installed in the filling pipeline, the second flow meter is installed in the inlet pipeline, and the third flow meter is installed in the return pipeline. The first flow meter is configured to monitor the liquid flow rate in the filling pipeline, the second flow meter is configured to monitor the liquid flow rate in the inlet pipeline, and the third flow meter is configured to monitor the liquid flow rate in the return pipeline.

[0010] By setting up the first, second, and third flow meters, real-time monitoring of the liquid flow rate in the corresponding pipelines (specifically, the filling pipeline, the inlet pipeline, and the return pipeline) can be achieved. This helps to further improve the replenishment accuracy of the automatic liquid supply and recovery equipment and reduce the risk of over- or under-replenishment. For example, when the liquid flow rate in the filling pipeline is detected to be too high, the flow velocity of the liquid in the filling pipeline can be reduced.

[0011] In some embodiments of this application, the automatic liquid supply and recovery device further includes a first liquid level sensor and a second liquid level sensor. The first liquid level sensor is installed in a first liquid storage tank, and the second liquid level sensor is installed in a second liquid storage tank. The first liquid level sensor is configured to monitor the liquid level in the first liquid storage tank, and the second liquid level sensor is configured to monitor the liquid level in the second liquid storage tank.

[0012] By setting up the first and second liquid level sensors, real-time monitoring of the liquid levels in the first and second storage tanks can be achieved. This allows technicians to replenish the liquid in the first and second storage tanks in real time, reducing the risk of emptying the liquid pipelines (specifically the filling pipeline, inlet pipeline, and return pipeline), thereby improving the stability and safety of the automatic liquid supply and recovery equipment.

[0013] In some embodiments of this application, the automatic liquid supply and recovery device further includes a first liquid filter and a second liquid filter. The first liquid filter is installed in the replenishment line, and the second liquid filter is installed in the inlet line. The first liquid filter is configured to filter the liquid flowing through the replenishment line, and the second liquid filter is configured to filter the liquid flowing through the inlet line.

[0014] By setting up the first and second liquid filters, impurities in the filtered liquid can be effectively blocked, thereby ensuring the cleanliness of the liquid entering the liquid cooling pipeline, and thus ensuring the normal operation and performance of external equipment.

[0015] In some embodiments of this application, the first liquid storage tank is provided with a first pressure relief valve, which is configured to release gas inside the first liquid storage tank when liquid from an external liquid source flows into the first liquid storage tank along the replenishment pipeline. The second liquid storage tank is provided with a second pressure relief valve, which is configured to release gas inside the second liquid storage tank when liquid from a liquid cooling pipeline flows into the second liquid storage tank along the inlet pipeline.

[0016] By setting up the first and second pressure relief valves, it is beneficial to automatically release excess gas in the first and second liquid storage tanks, so as to ensure that the pressure in the first and second liquid storage tanks is always kept within a safe range, thereby further improving the safety of the automatic liquid supply and recovery equipment.

[0017] In some embodiments of this application, the gas supply assembly further includes a gas filter installed in the air intake line, and the gas filter is configured to filter moisture and impurities in the compressed air.

[0018] By installing gas filters, it is beneficial to remove moisture and impurities from the gas, ensure gas quality, and thus protect liquid cooling pipelines from corrosion and damage.

[0019] In some embodiments of this application, the air supply assembly further includes a pressure sensor installed in the air intake line and configured to monitor pressure changes within the air intake line.

[0020] By installing pressure sensors, pressure changes in the gas pipeline can be monitored, reducing the risk of damage to the inlet pipeline due to excessive pressure. This helps to further improve the safety of automatic liquid supply and recovery equipment and reduce production costs.

[0021] In some embodiments of this application, the liquid replenishment and reflux assembly further includes a first liquid outlet pipe, which is configured to connect to a first liquid storage tank so that liquid in the first liquid storage tank can flow out along the first liquid outlet pipe.

[0022] The installation of the first liquid outlet pipeline allows the remaining liquid in the first liquid storage tank to be discharged, which facilitates subsequent maintenance or replacement of the first liquid storage tank.

[0023] In some embodiments of this application, the liquid recovery assembly further includes a second liquid outlet line configured to communicate with a second liquid storage tank so that liquid in the second liquid storage tank can flow out along the second liquid outlet line.

[0024] The installation of a second liquid outlet pipeline allows for the discharge of remaining liquid from the second storage tank, facilitating subsequent maintenance or replacement of the second storage tank. Attached Figure Description

[0032] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] This application provides an automatic liquid supply and recovery device. The automatic liquid supply and recovery device includes a liquid replenishment and return assembly, a liquid recovery assembly, and a gas supply assembly. The liquid replenishment and return assembly includes a first liquid storage tank, a liquid replenishment pipeline, and a filling pipeline. The liquid replenishment pipeline is configured to connect the first liquid storage tank and an external liquid source, allowing liquid from the external liquid source to flow into the first liquid storage tank along the liquid replenishment pipeline. The filling pipeline is configured to connect the first liquid storage tank and the inlet of a liquid-cooled pipe in an external device, allowing liquid in the first liquid storage tank to flow into the liquid-cooled pipe along the filling pipeline. The liquid recovery assembly includes a second liquid storage tank and an inlet pipeline. The inlet pipeline is configured to connect the second liquid storage tank and the outlet of the liquid-cooled pipe, allowing liquid in the liquid-cooled pipe to flow into the second liquid storage tank along the inlet pipeline. The air supply assembly includes an air compressor and an intake pipe. The intake pipe is configured to connect the air compressor and the inlet of the liquid cooling pipe. External air can be compressed by the air compressor and flow into the liquid cooling pipe along the intake pipe to discharge the liquid in the liquid cooling pipe.

[0036] In the aforementioned automatic liquid supply and recovery equipment, the liquid replenishment and reflux module assembly, the liquid reflux assembly, and the air supply assembly are independent of each other. Through the liquid replenishment and reflux module assembly, the liquid reflux assembly, and the air supply assembly, automatic liquid replenishment and drainage recovery of external equipment can be realized. This not only helps to improve the liquid replenishment efficiency and accuracy, making it suitable for efficient automated production lines, but also helps to reduce the labor intensity of workers.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Please see Figure 1 One embodiment of this application provides an automatic liquid supply and recovery device 100. The automatic liquid supply and recovery device 100 is used to supply liquid to liquid-cooled pipes in an external device 200 and to recover liquid from the liquid-cooled pipes in the external device 200. The external device 200 can be a server; this application does not limit this, and those skilled in the art can choose according to the actual situation.

[0039] Please refer to the following: Figures 1 to 3In some embodiments, the automatic liquid supply and recovery device 100 includes a liquid replenishment and return assembly 10, a liquid recovery assembly 20, and an air supply assembly 30. The liquid replenishment and return assembly 10 includes a first liquid storage tank 11, a liquid replenishment pipeline 12, and a liquid filling pipeline 13. The liquid replenishment pipeline 12 is configured to connect the first liquid storage tank 11 and an external liquid source 300 (specifically, a coolant storage device, a cleaning fluid storage device, or other liquid storage equipment) so that liquid in the external liquid source 300 can flow into the first liquid storage tank 11 along the liquid replenishment pipeline 12.

[0040] Understandably, when it is necessary to replenish the first storage tank 11 in the automatic liquid supply and recovery device 100, the external liquid source 300 can inject liquid into the first storage tank 11 along the replenishment pipeline 12 for storage. The replenishment pipeline 12 enables the replenishment of the first storage tank 11 in the automatic liquid supply and recovery device 100, which is beneficial for subsequent liquid filling operations of the automatic liquid supply and recovery device 100 on the external device 200.

[0041] In some embodiments, the filling line 13 is configured to connect the first liquid storage tank 11 and the inlet of the liquid cooling pipe in the external device 200, so that the liquid in the first liquid storage tank 11 can flow into the liquid cooling pipe along the filling line 13. Understandably, when it is necessary to fill the external device 200 with liquid, the liquid in the first liquid storage tank 11 can flow into the liquid cooling pipe of the external device 200 along the filling line 13.

[0042] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the liquid recovery assembly 20 includes a second liquid storage tank 21 and an inlet pipe 22, the inlet pipe 22 being configured to connect the second liquid storage tank 21 and the outlet of the liquid cooling pipe so that liquid in the liquid cooling pipe can flow into the second liquid storage tank 21 along the inlet pipe 22.

[0043] The air supply assembly 30 includes an air compressor 31 and an air intake pipe 32. The air intake pipe 32 is configured to connect the air compressor 31 and the inlet of the liquid cooling pipe. External air can be compressed by the air compressor 31 and flow into the liquid cooling pipe along the air intake pipe 32 to discharge the liquid in the liquid cooling pipe.

[0044] Understandably, when it is necessary to drain the liquid from the external device 200, the air compressor 31 compresses the outside air and delivers the compressed air to the liquid cooling pipe along the air inlet pipe 32. The liquid in the liquid cooling pipe is discharged into the second liquid storage tank 21 along the liquid inlet pipe 22 under the action of the compressed air, which means that the liquid in the external device 200 is recovered.

[0045] The automatic liquid supply and recovery equipment 100 provided in this application, through the cooperation of the liquid replenishment and return component 10, the liquid recovery component 20, and the air supply component 30, can realize automatic liquid replenishment and drainage recovery of external equipment 200. Compared with traditional manual liquid replenishment and recovery, it can not only improve the liquid replenishment efficiency and accuracy to be suitable for efficient automated production lines, but also reduce the labor intensity of workers.

[0046] Please refer to the following: Figure 1 and Figure 3 In some embodiments, the liquid replenishment and return assembly 10 further includes a return line 14, which is configured to connect the first liquid storage tank 11 and the outlet of the liquid cooling pipe, so that excess liquid in the liquid cooling pipe can be returned to the first liquid storage tank 11 through the return line 14.

[0047] Understandably, when the liquid in the first storage tank 11 flows into the liquid cooling pipe along the filling pipe 13, the excess liquid can flow back into the first storage tank 11 along the return pipe 14 and continue to flow into the liquid cooling pipe along the filling pipe 13 until the liquid cooling pipe in the external device 200 is completely filled.

[0048] The reflux pipeline 14 enables the circulation and replenishment of liquid to the external equipment 200. This improves the completeness of liquid replenishment to the external equipment 200, reducing the risk of incomplete replenishment by the automatic liquid supply and recovery equipment 100. Furthermore, it facilitates the recycling of liquid, reducing waste and lowering production costs.

[0049] Please see Figure 1 In some embodiments, the automatic liquid supply and recovery device 100 further includes a first flow meter 40a, a second flow meter 40b, and a third flow meter 40c. The first flow meter 40a is installed in the filling pipeline 13, the second flow meter 40b is installed in the inlet pipeline 22, and the third flow meter 40c is installed in the return pipeline 14.

[0050] The first flow meter 40a is configured to monitor the liquid flow rate of the filling line 13, the second flow meter 40b is configured to monitor the liquid flow rate of the inlet line 22, and the third flow meter 40c is configured to monitor the liquid flow rate of the return line 14.

[0051] Understandably, during the process of filling the external device 200 with liquid, the first flow meter 40a monitors the liquid flow rate through the filling pipeline 13 in real time. During the process of draining and recovering the external device 200 with liquid, the second flow meter 40b monitors the liquid flow rate in the inlet pipeline 22 in real time, and the third flow meter 40c monitors the liquid flow rate in the return pipeline 14 in real time.

[0052] When the corresponding flow meters (specifically the first flow meter 40a, the second flow meter 40b, and the third flow meter 40c) detect that the liquid flow rate in the corresponding pipeline (specifically the filling pipeline 13, the inlet pipeline 22, and the return pipeline 14) is too high, the automatic liquid supply and recovery device 100 can reduce the flow velocity of the liquid in the corresponding pipeline; conversely, the automatic liquid supply and recovery device 100 can increase the flow velocity of the liquid in the corresponding pipeline.

[0053] By setting up the first flow meter 40a, the second flow meter 40b, and the third flow meter 40c, real-time monitoring of the liquid flow rate in the corresponding pipeline can be achieved. The automatic liquid supply and recovery device 100 can automatically adjust the liquid flow rate in the corresponding pipeline based on the monitoring results to ensure that the liquid flow is always in a relatively balanced state. This not only helps to further improve the liquid replenishment accuracy of the automatic liquid supply and recovery device 100 and reduce the risk of over- or under-replenishment, but also improves the stability and efficiency of the liquid supply from the automatic liquid supply and recovery device 100.

[0054] It is worth noting that since the automatic liquid supply and recovery device 100 can automatically adjust the liquid flow rate in the corresponding pipeline, it helps to reduce the risk of liquid impacting or causing pressure changes on the automatic liquid supply and recovery device 100 due to improper control of the replenishment volume or excessive replenishment speed, thereby accelerating the wear or damage of the equipment. This helps to extend the service life of the automatic liquid supply and recovery device 100 and reduce subsequent maintenance costs.

[0055] Please see Figure 1 In some embodiments, the automatic liquid supply and recovery device 100 further includes a first liquid level sensor 50a and a second liquid level sensor 50b. The first liquid level sensor 50a is installed in the first liquid storage tank 11, and the second liquid level sensor 50b is installed in the second liquid storage tank 21. The first liquid level sensor 50a is configured to monitor the liquid level in the first liquid storage tank 11, and the second liquid level sensor 50b is configured to monitor the liquid level in the second liquid storage tank 21.

[0056] By setting up the first liquid level sensor 50a and the second liquid level sensor 50b, real-time monitoring of the liquid level in the first liquid storage tank 11 and the second liquid storage tank 21 can be achieved. This is beneficial for technicians to replenish the liquid in the first liquid storage tank 11 and the second liquid storage tank 21 in real time, reducing the risk of the liquid pipelines (specifically the filling pipeline 13, the inlet pipeline 22 and the return pipeline 14) being empty, thereby improving the stability and safety of the automatic liquid supply and recovery equipment 100.

[0057] Please refer to the following: Figure 1 , Figure 2 and Figure 4In some embodiments, the automatic liquid supply and recovery device 100 further includes a first liquid filter 60a and a second liquid filter 60b, wherein the first liquid filter 60a is installed in the replenishment line 12 and the second liquid filter 60b is installed in the inlet line 22. The first liquid filter 60a is configured to filter the liquid flowing through the replenishment line 12, and the second liquid filter 60b is configured to filter the liquid flowing through the inlet line 22.

[0058] By setting up the first liquid filter 60a and the second liquid filter 60b, impurities in the liquid can be effectively blocked and filtered, thereby ensuring the cleanliness of the liquid entering the liquid cooling pipeline, and thus ensuring the normal operation and performance of the external equipment 200.

[0059] In some embodiments, both the first liquid filter 60a and the second liquid filter 60b are reverse osmosis filters. Reverse osmosis filters use a semi-permeable membrane (pore size approximately 0.0001 micrometers) to force water molecules through the membrane under high pressure, while retaining impurities such as heavy metals, viruses, bacteria, and inorganic salts.

[0060] In other embodiments, the first liquid filter 60a and the second liquid filter 60b may also be other filtration structures such as activated carbon filters, ceramic filters, or filter membranes. The first liquid filter 60a and the second liquid filter 60b may be the same or different, and this application does not limit this; those skilled in the art can choose according to the actual situation.

[0061] Please see Figure 1 In some embodiments, the first liquid storage tank 11 is provided with a first pressure relief valve 111, which is configured to release gas inside the first liquid storage tank 11 when liquid from the external liquid source 300 flows into the first liquid storage tank 11 along the replenishment pipe 12. The second liquid storage tank 21 is provided with a second pressure relief valve 211, which is configured to release gas inside the second liquid storage tank 21 when liquid from the liquid cooling pipe flows into the second liquid storage tank 21 along the liquid inlet pipe 22.

[0062] By setting the first pressure relief valve 111 and the second pressure relief valve 211, it is beneficial to automatically discharge excess gas in the first liquid storage tank 11 and the second liquid storage tank 21, so as to ensure that the pressure in the first liquid storage tank 11 and the pressure in the second liquid storage tank 21 are always kept within a safe range, thereby further improving the safety of the automatic liquid supply and recovery equipment 100.

[0063] Please refer to the following: Figure 1 and Figure 4In some embodiments, the air supply assembly 30 further includes a gas filter 33, which is installed in the air inlet pipe 32 and configured to filter moisture and impurities in the compressed air. The gas filter 33 helps remove moisture and impurities from the gas, ensuring gas quality and thus protecting the liquid-cooled pipes from corrosion and damage.

[0064] In some embodiments, the gas filter 33 is an adsorption dryer. In other embodiments, the gas filter 33 may also be other filtration structures, which are not limited in this application, and those skilled in the art can choose according to the actual situation.

[0065] In some embodiments, the air supply assembly 30 further includes a pressure sensor 34, which is installed in the air intake line 32 and configured to monitor pressure changes within the air intake line 32.

[0066] By setting up pressure sensor 34, pressure changes in the gas pipeline can be monitored, reducing the risk of damage to the air inlet pipeline 32 due to excessive pressure. This helps to further improve the safety of the automatic liquid supply and recovery equipment 100 and reduce production costs.

[0067] For example, when the pressure in the intake pipe 32 is too high, the automatic liquid recovery device 100 can reduce the rate at which the air compressor 31 delivers compressed gas; conversely, it can increase the rate at which the air compressor 31 delivers compressed gas.

[0068] It is worth noting that monitoring pressure changes in the intake pipe 32 via the pressure sensor 34 also helps to monitor whether there are blockages or leaks in the pipes of the automatic liquid supply and recovery device 100. For example, when the pressure in the intake pipe 32 suddenly increases, it indicates that there may be a blockage in the intake pipe 32; when the pressure in the intake pipe 32 suddenly drops, it indicates that there may be a rupture or leak in the intake pipe 32.

[0069] Please see Figure 1 In some embodiments, the liquid replenishment and reflux assembly 10 further includes a first liquid outlet pipe 15, which is configured to connect to the first liquid storage tank 11 so that liquid in the first liquid storage tank 11 can flow out along the first liquid outlet pipe 15. The first liquid outlet pipe 15 allows residual liquid in the first liquid storage tank 11 to be drained, facilitating subsequent maintenance or replacement of the first liquid storage tank 11.

[0070] Please refer to the following: Figure 1 and Figure 5In some embodiments, the liquid recovery assembly 20 further includes a second liquid outlet pipe 23, which is configured to connect to the second liquid storage tank 21 so that liquid in the second liquid storage tank 21 can flow out along the second liquid outlet pipe 23. The second liquid outlet pipe 23 allows residual liquid in the second liquid storage tank 21 to be discharged, facilitating subsequent maintenance or replacement of the second liquid storage tank 21.

[0071] For example, the working process of the automatic liquid supply and recovery device 100 provided in this application is as follows:

[0072] When replenishing the first storage tank 11 in the automatic liquid supply and recovery equipment 100, the solenoid valve in the return pipeline 14 and the solenoid valve in the filling pipeline 13 are both in the closed state, and the solenoid valve in the replenishment pipeline 12 is in the open state. The external liquid source 300 injects liquid into the first storage tank 11 along the replenishment pipeline 12.

[0073] When the external device 200 is filled with liquid, the solenoid valve in the return line 14 and the solenoid valve in the filling line 13 are both in the open state, and the solenoid valve in the replenishment line 12 is in the closed state. The liquid in the first storage tank 11 flows along the filling line 13 and flows into the liquid cooling pipe of the external device 200 through the one-way valve.

[0074] Meanwhile, excess liquid in the liquid cooling pipes can flow back to the first storage tank 11 along the return pipe 14. The liquid flowing back to the first storage tank 11 continues to flow into the liquid cooling pipes along the filling pipe 13. This cycle continues until the liquid cooling pipes in the external device 200 are completely filled.

[0075] When draining liquid from external equipment 200, the solenoid valves in the return line 14, the filling line 13, and the replenishment line 12 are all closed, while the solenoid valves in the air inlet line 32 and the liquid inlet line 22 are open. The air compressor 31 compresses external air and delivers the compressed air along the air inlet line 32 to the liquid cooling pipe. The liquid in the liquid cooling pipe is then discharged along the liquid inlet line 22 into the second storage tank 21 under the action of the compressed air.

[0076] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
