[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0045] Secondly, it should be noted that in the description of the present application, terms such as "front", "rear", "left", "right", "up", "down", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0046] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present disclosure. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0048] With the rapid development of technologies such as artificial intelligence, cloud computing, and big data, the demand for computing power in all walks of life is increasing. For example, in the field of AI, the evolution of new technologies such as large models has caused the demand for computing power to double every six months. The power density of server chips continues to increase, and the existing air cooling system has gradually reached its heat dissipation limit and cannot effectively dissipate the large amount of heat generated by high-power chips, which may cause the server temperature to be too high, affecting its performance and stability.

[0049] As the main carrier of computing power, data centers need to meet demand through continuous "capacity expansion", but this leads to a continuous increase in the power consumption of hardware devices such as server processors, and the overall energy consumption of data centers also grows rapidly.

[0050] In traditional air cooling solutions, the energy consumption of cooling fans and corresponding power supply and distribution often accounts for 20%-30% of the total energy consumption of data centers. However, after years of development, the marginal benefits of further optimization and improvement of air cooling technology are very limited, making it difficult to cope with the growing heat dissipation demand and energy consumption challenges.

[0051] PUE, short for Power Usage Effectiveness, is an indicator for evaluating the energy efficiency of data centers. It is the ratio of all energy consumed by data centers to the energy consumed by IT loads. Currently, the PUE values ​​of most data centers are above 1.5. As a high-energy-consuming industry, data centers need to use various energy-saving and emission-reduction plans to reduce PUE and other energy consumption indicators and improve green environmental protection levels.

[0052] To this end, the traditional low-power air cooling system of the data center is transformed into a liquid cooling system. The liquid cooling system includes a cooling water pipeline and a cooling distribution unit. The cooling water pipeline is connected to the cooling distribution unit. The cooling distribution unit controls the flow of the cooling water pipeline to reasonably dissipate heat in the data center.

[0053] However, the water quality of the cooling water in the cooling water pipeline has a certain negative effect on the cooling distribution unit. For example, impurities in the cooling water may clog the cooling water pipeline or the cooling distribution unit, or other chemical components in the cooling water may have a certain corrosive effect on the cooling water pipeline or the cooling distribution unit, thereby affecting the heat dissipation effect of the liquid cooling system. In order to ensure the heat dissipation effect of the liquid cooling system, the cooling water pipeline of the liquid cooling system needs to be shut down for cleaning and maintenance. If the liquid cooling system is shut down, the heat generated by the data center cannot be effectively dissipated, and the data center may even need to be shut down at the same time, affecting the normal operation of the data center.

[0054] Based on the above technical problems, an embodiment of the present application provides a liquid cooling and heat dissipation system, including a water supply pipeline, a return water pipeline, a cooling distribution unit, a water pump and a self-cleaning filter; the water supply pipeline is connected to the water inlet of the cooling distribution unit, and the return water pipeline is connected to the water outlet of the cooling distribution unit; the water pump is connected to the water supply pipeline; the self-cleaning filter is connected to the water supply pipeline and is arranged on the water inlet side of the water pump; the self-cleaning filter includes a filter body and a cleaning device, and the filter body is connected to the water supply pipeline; the cleaning device is connected to the filter body, and the cleaning device is configured to clean the inside of the filter body. By setting up a self-cleaning filter, the cooling water in the water supply pipeline can be filtered, and the impurities in the cooling water in the water supply pipeline are attached to the filter body. At the same time, the cleaning device can clean the filter body to ensure that the filter body continues to filter the water supply pipeline, avoid shutting down the liquid cooling and heat dissipation system for cleaning and maintenance, improve the heat dissipation effect of the liquid cooling and heat dissipation system, and ensure the normal and continuous operation of the data center.

[0055] It should be noted that Figures 1 to 5 The schematic diagram of each component in the liquid cooling system is shown. The specific structure of the other components in the liquid cooling system is not limited to Figures 1 to 5 of examples.

[0056] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0057] Reference Figures 1 to 5 As shown, a liquid cooling system provided in an embodiment of the present application includes but is not limited to being used for heat dissipation in a data center 10, wherein the liquid cooling system includes a water supply pipeline 100, a return pipeline 200, a cooling distribution unit 300, a water pump 400 and a self-cleaning filter 500.

[0058] The water supply pipeline 100 is connected to the water inlet of the cooling distribution unit 300 , and the water return pipeline 200 is connected to the water outlet of the cooling distribution unit 300 .

[0059] The water pump 400 is connected to the water supply pipeline 100 ; the self-cleaning filter 500 is connected to the water supply pipeline 100 and is arranged on the water inlet side of the water pump 400 .

[0060] The self-cleaning filter 500 includes a filter body 510 and a cleaning device 520 . The filter body 510 is in communication with the water supply pipeline 100 . The cleaning device 520 is connected to the filter body 510 , and is configured to clean the interior of the filter body 510 .

[0061] In the above-mentioned setting method, by setting a self-cleaning filter 500, the cooling water in the water supply pipe 100 can be filtered. Here, the self-cleaning filter 500 can not only filter impurities in the cooling water, but also adsorb other components in the cooling water, such as corrosive chemical components or impurities such as microorganisms. The embodiment of the present application does not limit this.

[0062] By providing a self-cleaning filter 500, impurities in the cooling water in the water supply pipe 100 can be attached to the filter body 510. At the same time, the cleaning device 520 can clean the filter body 510 to ensure that the filter body 510 continues to filter the water supply pipe 100, avoiding the shutdown of the liquid cooling system for cleaning and maintenance, improving the heat dissipation effect of the liquid cooling system, and ensuring the normal operation of the data center.

[0063] In addition, the self-cleaning filter 500 is arranged on the water inlet side of the water pump 400, which can filter the cooling water entering the water pump 400, and can also prevent the cooling water from corroding the water pump 400 or impurities from clogging the water pump 400, thereby ensuring the normal operation of the water pump 400 and improving reliability.

[0064] In one possible implementation, please refer to Figure 1 and Figure 2 As shown, the filter body 510 includes a filter cylinder 511 and a filter element 512. The filter cylinder 511 is connected to the water supply pipeline 100, and the filter element 512 is arranged in the filter cylinder 511 to filter impurities in the water supply pipeline 100. In specific implementation, the filter cylinder 511 can be a cylindrical cylinder or a square tube cylinder. The embodiment of the present application does not make specific restrictions on this. In the embodiment of the present application, the filter cylinder 511 is a cylindrical cylinder to facilitate manufacturing and installation of the filter element 512.

[0065] The filter element 512 may also be cylindrical, which can increase the actual effective area of ​​the filter element 512 and improve the use effect of the filter element 512. The filter element 512 is nested in the filter cylinder 511, and the internal space of the filter cylinder 511 can also be effectively utilized. In specific implementation, the filter element 512 is a filter screen, which includes a coarse filter layer, a fine filter layer and an ultrafiltration layer that are nested in sequence to filter impurities of different particle sizes and improve the filtering effect.

[0066] The cleaning device 520 includes a debris removal mechanism 521 and a sewage discharge mechanism. The debris removal mechanism 521 is arranged inside the filter cylinder 511, and the debris removal mechanism 521 is configured to be opposite to the filter element 512 and is used to remove impurities on the filter element 512. The sewage discharge mechanism connects the inside of the filter cylinder 511 and the outside of the self-cleaning filter 500 to discharge impurities.

[0067] In a specific implementation, the impurity removal mechanism 521 includes at least one of the following: a nozzle 5231 , a suction member 522 , and a scraping member 525 .

[0068] Reference Figure 2 As shown, the impurity removal mechanism 521 has a sewage suction port 5211 and a sewage discharge port 5212. The sewage suction port 5211 is opposite to the inner wall of the filter element 512 for sucking impurities on the filter element 512. The suction element 522 is connected to the sewage discharge port 5212 of the impurity removal mechanism 521 for discharging impurities.

[0069] It should be noted that the filter element 512 is a prior art in the relevant field, and the embodiment of the present application does not limit the specific structure of the filter element 512. The filter element 512 can be rotatably arranged in the filter cylinder 511 to rotate and suck impurities on the filter element 512 to improve the cleaning effect. The suction element 522 can be a motor that can provide negative pressure suction force. This part is a prior art in the relevant field and will not be described in detail here.

[0070] In the above embodiment, the cooling water in the water supply pipeline 100 enters the filter cylinder 511, is filtered by the filter element 512, and the filtered cooling water flows out of the filter cylinder 511. In this process, impurities in the cooling water are filtered by the filter element 512 and attached to the filter element 512. When the impurities accumulate to a certain amount, the suction element 522 can be turned on. At this time, the impurity removal mechanism 521 absorbs the impurities attached to the filter element 512 and discharges them through the suction element 522 to clean the filter element 512. The continuous operation of the filter element 512 can be ensured to avoid clogging of the filter element 512 due to excessive impurities and affect the filtering effect.

[0071] In one possible implementation, a differential pressure detection device (not shown in the drawings), such as a differential pressure sensor, is provided in the filter cylinder 511. When impurities on the filter element 512 accumulate to a certain amount, the pressure in the filter cylinder 511 will inevitably increase. When the differential pressure detection device detects that the pressure in the filter cylinder 511 increases to a preset pressure value, the cleaning device 520 is controlled to open to clean the filter cylinder 511, thereby automating the cleaning process of the filter cylinder 511 and reducing human intervention.

[0072] In another possible implementation, refer to Figure 3As shown, the cleaning device 520 may further include at least one scraper 525 and a sewage pipe 524, wherein the scraper 525 abuts against the inner wall of the filter cylinder 511, and the scraper 525 may be rotatably arranged in the filter cylinder 511, and the scraper 515 is driven by a motor to rotate to scrape off impurities on the filter element 512, and the sewage pipe 524 is used to connect the interior of the filter cylinder 511 and the exterior of the self-cleaning filter 500, and the suction member 522 may also be arranged on the sewage pipe 524. The scraped impurities are discharged from the filter cylinder 511 through the sewage pipe 524, and the scraper 525 is arranged to make the internal structure of the filter cylinder 511 simple, easy to install, and help reduce the manufacturing and maintenance costs. In specific implementation, the scraper 525 may be a plate-shaped scraper or a cleaning brush.

[0073] In another possible implementation, refer to Figure 4 As shown, the cleaning device 520 includes a flushing mechanism 523 and a sewage pipe 524 , and the sewage pipe 524 is used to connect the inside and the outside of the filter cylinder 511 .

[0074] The flushing mechanism 523 includes at least one nozzle 5231 , which is disposed inside the filter cylinder 511 and is configured to be opposite to the filter element 512 and used to flush impurities on the filter element 512 so that the impurities are discharged through the sewage pipe 524 .

[0075] In the above embodiment, the nozzle 5231 is arranged inside the filter cylinder 511. In the relevant technical field, the nozzle 5231 is used to communicate with an external water supply device to spray water to the inner wall of the filter element 512 to wash away the impurities attached to the filter element 512. The number of nozzles 5231 can be set to multiple, and the height of each nozzle 5231 relative to the filter element 512 can be designed according to actual conditions so that the water sprayed by each nozzle 5231 covers more of the inner wall of the filter element 512 to improve the cleaning effect. Alternatively, the nozzle 5231 can rotate or rise and fall to further improve the cleaning effect. The embodiment of the present application does not limit the specific structure of the nozzle 5231. The washed impurities are discharged from the filter cylinder 511 through the sewage pipe 514.

[0076] It should be noted here that the impurity removal mechanism 521 may include one of the nozzle 5231, the suction piece 522 and the scraper 525, and of course it can also be a combination of two or three of the nozzle 5231, the suction piece 522 and the scraper 525, and its specific usage has been described above.

[0077] In one possible implementation, the water supply pipeline 100 includes a water supply main 110 and multiple water supply branches 120, one end of each water supply branch 120 is connected to the water supply main 110, and the other end is connected to a different cooling distribution unit 300, and multiple water supply branches 120 are arranged in parallel.

[0078] A water pump 400 and a self-cleaning filter 500 are provided in each water supply branch 120 .

[0079] The return water pipeline 200 includes a return water main pipe 210 and a plurality of return water branches 220 . One end of each return water branch 220 is connected to the return water main pipe 210 , and the other end is connected to a different cooling distribution unit 300 . The plurality of return water branches 220 are arranged in parallel.

[0080] In this way, by setting up multiple water supply branches 120 and multiple return branches 220 in parallel, the liquid cooling system can be adapted to components that require heat dissipation in multiple data centers 10, thereby improving the heat dissipation effect of the liquid cooling system provided in the embodiment of the present application.

[0081] In the above embodiment, the water supply pipeline 100 further includes a first loop pipeline 130 , and each of the water supply branches 120 is connected to the first loop pipeline 130 ; the first loop pipeline 130 is connected to each of the cooling distribution units 300 .

[0082] On the first loop pipeline 130 , first control valves 150 are respectively provided on both sides of the connection position with the water supply branch 120 .

[0083] And / or, the water return pipeline 200 further includes a second loop pipeline 230 , each of the water return branches 220 is connected to the second loop pipeline 230 , and the second loop pipeline 230 is connected to each of the cooling distribution units 300 .

[0084] On the second loop pipeline 230 , second control valves 240 are respectively provided on both sides of the connection position with the return water branch 220 .

[0085] By setting the first loop pipe 130, the plurality of water supply branches 120 are all connected to the first loop pipe 130. When one or more of the water supply branches 120 need to be repaired or need to be repaired or replaced due to a fault, the flow direction of the cooling water in the first loop pipe 130 can be controlled by the first control valve 150. Figure 1 As shown, during normal operation, Figure 1There are two left and right first control valves 150 at the connection position between the left water supply branch 120 and the first loop pipe 130. At this time, the left first control valve 150 is opened and the right first control valve 150 is closed, so that the cooling water in the left water supply branch 120 is input into the left cooling distribution unit 300 through the left first control valve 150 and the left part of the first loop pipe 130. Figure 1 There are two left and right first control valves 150 at the connection position between the right water supply branch 120 and the first loop pipe 130. At this time, the left first control valve 150 is closed and the right first control valve 150 is opened, so that the cooling water in the right water supply branch 120 is input into the cooling distribution unit 300 on the right through the right first control valve 150 and the right part of the first loop pipe 130.

[0086] When the left water supply branch 120 needs to be inspected or fails and needs to be repaired and replaced, at this time, the two left and right first control valves 150 at the connection position of the left water supply branch 120 and the first loop pipe 130 are controlled to be opened, and the two left and right first control valves 150 at the connection position of the right water supply branch 120 and the first loop pipe 130 are controlled to be opened. At this time, the cooling water in the right water supply branch 120 will fill the first loop pipe 130 to be input into different cooling distribution units 300.

[0087] It should be noted that the above opening and closing of the first control valve 150 is only an example, and the specific implementation is not limited to the above control method of the first control valve 150, and it is only used to illustrate that the flow direction of the cooling water in the first loop pipe 130 can be controlled by the first control valve 150. Similarly, the above example is also applicable to the opening and closing of the second control valve 240.

[0088] This avoids the need for overall downtime for repairs when one of the water supply branches 120 fails, thereby further ensuring continuous heat dissipation of the data center 10 and improving the heat dissipation effect.

[0089] Similarly, by setting up the second loop pipe 230, multiple water return branches 220 are all connected to the second loop pipe 230. When one or more water return branches 220 need to be repaired or fail and need to be repaired and replaced, the second control valve 240 can be used to control the flow direction of cooling water in the second loop pipe 230 to ensure the normal operation of other water return branches 220 and avoid the need for overall shutdown for repair after a water return branch 220 fails. In this way, continuous heat dissipation of the data center 10 can be ensured, and the heat dissipation effect can be improved.

[0090] In summary, by providing the first loop pipe 130 and the second loop pipe 230 , it is possible to avoid the entire liquid cooling system from shutting down, thereby ensuring continuous heat dissipation of the data center 10 and ensuring normal heat dissipation of the data center 10 .

[0091] Please continue to refer to Figure 1 The water supply pipeline 100 includes an emergency branch 140 , which is connected in parallel with the water supply branch 120 and is connected between the water supply main 110 and the first loop pipeline 130 ; the emergency branch 140 is provided with a third control valve 160 .

[0092] By setting up the emergency branch 140, it is possible to ensure the continuous supply of cooling water to the cooling distribution unit 300 when all water supply branches 120 fail. Alternatively, it can be understood that when the heat of the data center 10 increases suddenly, a large amount of cooling water is suddenly needed for heat dissipation, and the water supply branch 120 cannot cope with the sudden situation, the emergency branch 140 can be opened by the third control valve 160 to cope with the sudden increase in heat. It is additionally explained here that in the prior art, valves are provided at both ends of the water supply branch 120, and the valves can control the on and off of the water supply branch 120. When the water supply branch 120 fails, the valve can be controlled to close the water supply branch 120. To facilitate emergency repairs to the water supply branch 120, the embodiment of the present application does not specifically limit the valve in the water supply branch 120.

[0093] In order to conveniently record the temperature and pressure conditions in the water supply pipeline 100 and the return water pipeline 200, to ensure the normal operation of the water supply pipeline 100 and the return water pipeline 200, and to facilitate the regulation of the cooling water flow conditions of the water supply pipeline 100 and the return water pipeline 200. The liquid cooling system also includes a plurality of temperature sensors 600 and a plurality of pressure sensors 700, and the water supply pipeline 100 and the return water pipeline 200 are both provided with temperature sensors 600 and pressure sensors 700.

[0094] The temperature sensor 600 is configured to detect the temperature of the cooling water in the water supply pipeline 100 and / or the water return pipeline 200 ; the pressure sensor 700 is configured to detect the pressure of the cooling water in the water supply pipeline 100 or the water return pipeline 200 .

[0095] In another possible implementation, at least one temperature sensor 600 is disposed on the water inlet side of the water pump 400 , so that the temperature of the cooling water entering the water pump 400 can also be detected to facilitate regulation of the flow rate of the cooling water entering the water pump 400 .

[0096] Please continue to refer to Figure 1 The liquid cooling system also includes a secondary filter 800 , which is connected between the self-cleaning filter 500 and the water pump 400 .

[0097] In this way, it can be understood that the water pump 400 is a prior art in the relevant field. There are many related parts in the water pump 400, and the water quality requirements are relatively high. If there are too many impurities, the water pump 400 may be blocked. For this reason, by setting a secondary filter 800, the cooling water can be filtered for the second time, and the fine impurities in the cooling water can be further filtered out to ensure the normal operation of the water pump 400.

[0098] In a specific implementation, the secondary filter 800 may be a Y-type filter. The Y-type filter has the characteristics of simple structure, small resistance, convenient sewage discharge, etc., and the Y-type filter has low cost.

[0099] It should be noted here that the liquid cooling system is used to cool the indoor environment of the data center 10 .

[0100] Reference Figure 3 As shown, the water supply pipeline 100 and the water return pipeline 200 are both arranged under the floor of the data center 10. The floor of the data center 10 is usually an elevated bracket 20 in the relevant field, and there is a large available space under the elevated bracket 20. By arranging the water supply pipeline 100 and the water return pipeline 200 under the floor of the data center 10, that is, under the elevated bracket 20, the space under the elevated bracket 20 can be fully utilized, thereby improving the space utilization rate.

[0101] In order to promptly detect water leakage in the water supply pipeline 100 and the water return pipeline 200 , the water supply pipeline 100 and the water return pipeline 200 are both provided with leakage detection lines, which are arranged along the extension direction of the water supply pipeline 100 and the water return pipeline 200 .

[0102] Specifically, the leakage detection line can be a leakage rope, which is an existing technology in the relevant field. It can detect in real time whether the water supply pipeline 100 and the return pipeline 200 are leaking and activate the alarm. It can detect leakage in time and prompt maintenance and replacement.

[0103] The implementation principle of a liquid cooling and heat dissipation system in an embodiment of the present application is as follows: the liquid cooling and heat dissipation system provided by the present application includes a water supply pipeline 100, a water return pipeline 200, a cooling distribution unit 300, a water pump 400 and a self-cleaning filter 500; the water supply pipeline 100 is connected to the water inlet of the cooling distribution unit 300, and the water return pipeline 200 is connected to the water outlet of the cooling distribution unit 300; the water pump 400 is connected to the water supply pipeline 100; the self-cleaning filter 500 is connected to the water supply pipeline 100 and is arranged on the water inlet side of the water pump 400; the self-cleaning filter 500 0 includes a filter body 510 and a cleaning device 520. The filter body 510 is connected to the water supply pipeline 100. The cleaning device 520 is configured to clean the interior of the filter body 510. By setting a self-cleaning filter 500, the filter body 510 can filter impurities in the cooling water. At the same time, the cleaning device 520 can clean the filter body 510 to ensure that the filter body 510 continues to filter the water supply pipeline, avoid shutting down the liquid cooling system for cleaning and maintenance, improve the heat dissipation effect of the liquid cooling system, and ensure that the data center 10 works normally and continuously.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solution to deviate from the scope of the technical solution of the embodiments of the present application.
