[0002] Indirect evaporative cooling technology is an efficient data center cooling solution. It is usually applied in the cooling system. It uses the characteristic that the wet bulb temperature of air is lower than the dry bulb temperature. The outdoor air is cooled by evaporation to approach the wet bulb temperature, and then exchanges heat with the indoor air through an air-to-air heat exchanger to obtain an indoor air supply temperature that meets the requirements, thereby improving heat exchange efficiency, extending the natural cooling time, and reducing the energy consumption of the data center server group.

[0003] The cooling system generally has a water system, which uses a water pump to pump water from the water collecting tank to the spray system for spraying to cool the outdoor air. The spray water is recovered through the water collecting tank and then pumped out by the water pump to form a water circulation system.

[0004] In this way, substances such as catkins and sand in the outdoor air will be brought into the water circulation system, and the pipes of the water circulation system will easily become dirty and blocked, which may affect the spraying effect of the cooling system. Summary of the invention

[0033] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0035] Figure 1 The invention is a block diagram showing a cooling system for a server cluster according to an exemplary embodiment.

[0036] like Figure 1As shown, the cooling system 10 includes: a water supply system 101, which is arranged outside the unit of the server cluster and is connected to the water circulation system 102, and is used to transport external clean water to the water circulation system 102; the water circulation system 102 is arranged inside the unit of the server cluster, wherein the water circulation system 102 includes a spray device 1021, and the spray device 1021 is used to cool the unit by spraying water; a control system 103, which is used to switch the working mode of the cooling system 10, wherein, if it is detected that the water quality of the external clean water does not meet the water quality requirements, a first mode conversion signal is generated, and the first mode conversion signal is used to stop transporting the external clean water to the water circulation system 102, and start the water collection tank 204 of the water circulation system 102 to provide water for spraying to the spray device 1021.

[0037] Usually, the water supply system 101 of the server cluster is configured in an outdoor environment. When there are many impurities in the outdoor air, catkins and sand are easily pumped into the water supply system 101 by the water pump, which causes the water supply pipes in the water supply system 101 to become dirty and blocked, and the spraying fails. Therefore, in the embodiment of the present disclosure, the water quality of the external purified water can be detected, and the water quality can be used to characterize the degree of dirtiness of the external purified water.

[0038] That is to say, in the embodiment of the present disclosure, the water quality of external clean water can be quantified into a parameter value describing the degree of dirtiness. This parameter value can be called water quality, which can effectively assist in the subsequent use of the water quality to determine the timing of switching the working mode of the cooling system 10.

[0039] In some embodiments, the water quality of the external purified water can be detected during the startup of the cooling system 10, or the water quality of the external purified water can be detected when the cooling system 10 is not started, without limitation.

[0040] In other embodiments, the water quality of the external purified water may be detected in real time, or the water quality of the external purified water may be detected at preset time intervals (the preset time period is, for example, 1 day), without limitation.

[0041] In some embodiments, an environmental detector connected to the water tank can be configured for the cooling system 10. Thus, the step of detecting the water quality of external purified water can include: using the environmental detector to detect the material component values ​​in the air of the environment in which the water tank is located; analyzing the material component values ​​detected by the environmental detector to obtain the water quality of the external purified water.

[0042] In the embodiment of the present disclosure, when an environmental detector connected to a water tank is configured for the cooling system 10, the environmental detector can be used to detect the material composition value in the air of the environment in which the water tank is located, and the detected material composition value is sent to the central processing unit in the cooling system 10. The central processing unit combines the comparison relationship between the material composition value and the pre-configured composition value, and thus determines the corresponding water quality based on the comparison relationship.

[0043] It is understandable that since the water tank is not a closed setting, when the air in the environment where the water tank is located is relatively dirty, it can be correspondingly determined that the water in the water tank is also relatively dirty. Therefore, in the embodiment of the present disclosure, when the central processor determines the dirtiness value corresponding to the air in the environment based on the comparison relationship, the dirtiness value of the environment can be directly used as the water quality of the external purified water, thereby improving the comprehensiveness and convenience of the detection while effectively ensuring the water quality detection effect of the external purified water.

[0044] For example, suppose the environmental detector detects that the content of substance component A in the ambient air is A1, and the content of substance component B is B1, and the pre-configured component values ​​in the central processor are: when the content of A is A1, and the content of B is B1, the water quality is determined to be 100.

[0045] In some other embodiments, a material detector connected to the filter on the water tank can be configured for the water tank of the cooling system 10. The material detector can be used to detect the content of the substance filtered by the filter covering the water tank; the content value can be analyzed to obtain the turbidity of the external clean water, and the turbidity can be used as the water quality.

[0046] In the embodiment of the present disclosure, when a material detector connected to the filter on the water tank is configured, the material detector can be used to detect the content value of the substance filtered by the filter covering the water tank, thereby sending the content value of the filtered substance to the central processing unit in the cooling system 10. The central processing unit determines the turbidity of the water based on the content value of the filtered substance and the pre-configured detection rules, and thus uses the turbidity as the external clean water quality, thereby quantifying the external clean water quality. This can effectively assist the subsequent use of water quality to determine the timing of switching the working mode of the cooling system 10, thereby ensuring the detection effect of the external clean water quality.

[0047] Of course, in some other embodiments, any other possible methods can be used to detect the external purified water quality. For example, an environmental image of the environment in which the water tank is located can be obtained, and the environmental image can be analyzed to obtain the characteristics of each pixel point. The characteristics of each pixel point can be analyzed to obtain the turbidity of the air in the environment and match the corresponding water quality. There is no limitation to this.

[0048] In some other embodiments, a water quality detector may be disposed in the water tank to detect the turbidity of the water inside the water tank and match the corresponding water quality. In the process of matching the corresponding water quality, the matching rules may be flexibly set according to actual usage requirements and are not limited to the contents of the above examples.

[0049] The above-mentioned water quality requirements may be pre-configured, for example, may be configured in the control system 103, specifically, may be pre-configured by the factory program of the cooling system 10 for the server cluster, or may be customized by the user, without limitation.

[0050] When it is detected that the water quality of external purified water does not meet the water quality requirements, it indicates that the external purified water is highly polluted. At this time, a first mode conversion signal can be triggered to stop delivering external purified water to the water circulation system 102, and start the water collection tank 204 of the water circulation system 102 to provide water for spraying for the spray device 1021.

[0051] Since the water collecting tank 204 of the water circulation system 102 is arranged inside the unit of the server cluster, the water therein can be pre-filled and is not easily affected by impurities in the outdoor air. Therefore, when the water quality of the external purified water does not meet the water quality requirements, the water collecting tank 204 of the water circulation system 102 is started to provide spraying water for the spraying device 1021, which can effectively avoid the influence of the dirt of the external purified water on the spraying effect, realize the sustainability of the spraying effect of the cooling system 10, and thus ensure the cooling effect of the cooling system 10.

[0052] In the embodiment of the present disclosure, the architecture of the cooling system 10 is improved, and the external water supply system 101 and the water circulation system 102 are connected, so that the auxiliary cooling system 10 can switch the working mode according to the water quality of the external purified water. If it is detected that the water quality of the external purified water does not meet the water quality requirements, a first mode conversion signal is generated. The first mode conversion signal is used to stop the external purified water from being delivered to the water circulation system 102, and to start the water collection tank 204 of the water circulation system 102 to provide water for spraying for the spray device 1021. When it is detected that the water quality of the external purified water meets the water quality requirements, a second mode conversion signal is generated. The second mode conversion signal is used to start the water supply system 101 to deliver the external purified water to the water circulation system 102, so that the spray device 1021 uses the external purified water as the spray water, so that any of the two water supply pipelines can be used to provide the nozzle with water for spraying, so that the working mode of the cooling system 10 can be automatically switched, thereby ensuring the continuity of the cooling control of the entire process of the cooling system 10 and effectively improving the spraying effect.

[0053] In some embodiments of the present disclosure, the water supply system 101 is connected to the spray device 1021, wherein the control system 103 sends a second mode conversion signal to the water supply system 101, and the water supply system 101 responds to the second mode conversion signal to open the external delivery pipeline 104, and the external delivery pipeline 104 is used to deliver external clean water to the spray device 1021. The implementation is simple, does not increase excessive structural modification costs, and has good practicality.

[0054] The water circulation system 102 may be provided with a plurality of water supply pipelines, so that different water supply pipelines can be used to provide water for spraying to the spraying device 1021. The specific description is as follows:

[0055] See also Figure 2 , Figure 2 It is a block diagram of a cooling system 10 for a server cluster according to another exemplary embodiment. In the present disclosure, the cooling system 10 includes a unit body 20, and a first water supply pipeline 201, a second water supply pipeline 202, a nozzle 203 and a water collecting tank 204 are arranged inside the unit body 20, and the first water supply pipeline 201, the second water supply pipeline 202 and the water collecting tank 204 can all be regarded as components in the water circulation system 102, and the nozzle 203 can be a component belonging to the spray device 1021. Accordingly, the spray device 1021 in this embodiment also includes a spray pipeline connected to the nozzle 203, which is alternately connected with other water supply pipelines through the spray pipeline, thereby assisting in switching the working mode of the cooling system 10.

[0056] The first water supply pipeline 201 can be connected between the nozzle 203 and the water collecting tank 204, and the second water supply pipeline 202 is connected between the nozzle 203 and the water storage tank 205. The water storage tank 205 is usually arranged outside the unit body 20. The water storage tank 205 can be specifically a component of the return water system 21 in the embodiment of the present disclosure. The first water supply pipeline 201 can be specifically composed of a first sub-pipeline 2011, a second sub-pipeline 2012, and a third sub-pipeline 2013. The second water supply pipeline 202 can be specifically composed of a third sub-pipeline 2013, a fourth sub-pipeline 2014, and a second sub-pipeline 2012 (the second sub-pipeline 2012 can be regarded as a spray pipeline, one end of which is connected to the nozzle 203, and the other end can be respectively connected to various water supply pipelines), wherein the third sub-pipeline 2013 can be regarded as a public water supply pipeline, and external clean water can be supplied to the water collecting tank 204 via the third sub-pipeline 2013.

[0057] That is, the third sub-pipeline 2013 can be selected to supply water to the first water supply pipeline 201 or the second water supply pipeline 202 through the three-way valve 208. Figure 2The figure also shows a drainage pipeline 301, which is connected to the water collecting tank 204, the return water system 21, and the water storage tank 205. When the first water supply pipeline 201 supplies water, the third sub-pipeline 2013, the first sub-pipeline 2011, the second sub-pipeline 2012, and the water collecting tank 204 form a unit spray cycle, and when the second water supply pipeline 202 supplies water, the third sub-pipeline 2013, the fourth sub-pipeline 2014 (the combination of the third sub-pipeline 2013 and the fourth sub-pipeline 2014 can be regarded as the external delivery pipeline 104), the second sub-pipeline 2012 ( The second sub-pipeline 2012 can be regarded as a spray pipeline, one end of which is connected to the nozzle 203, and the other end can be connected to various water supply pipelines respectively). That is to say, when the second sub-pipeline 2012 is connected to the external delivery pipeline 104, a unit spray cycle can be formed, and when the water in the water collecting tank 204 is purified, the water in the water collecting tank 204 is output to the return water system 21 via the drainage pipeline 301. The water pump on the third sub-pipeline 2013 is the water pump of the unit water supply system 101, and the water supply system 101 is set independently of the unit body.

[0058] When the cooling system 10 is working, the external clean water in the water storage tank 205 is transported to the water circulation system 102. The water collecting tank 204 in the water circulation system 102 is set in the unit body 20. When there is a spraying demand, the water in the water collecting tank 204 is pumped into the first water supply pipeline 201 to transport the spraying water to the nozzle 203 via the first water supply pipeline 201, so as to complete the spraying operation to the air-to-air heat exchanger inside the unit body 20.

[0059] In some embodiments of the present disclosure, the water collecting tank 204 is also used to recover water sprayed by the spraying device 1021; the control system 103 is also used to generate a recovery signal when it is detected that the water quality of the water collecting tank 204 does not meet the water quality requirements, and the recovery signal is used to stop the water collecting tank 204 from providing water for spraying to the spraying device 1021, and control the water in the water collecting tank 204 to be discharged to the return water system 21.

[0060] In some embodiments of the present disclosure, see Figure 2 and Figure 3 , Figure 3 It is a block diagram of a cooling system 10 for a server cluster according to another exemplary embodiment, wherein a spray device 1021 includes a spray pipeline, one end of which is connected to a nozzle, and the other end is connected to a water supply pipeline, wherein the water supply pipeline is respectively connected to the water supply system 101 and the water collecting tank 204 through a three-way valve, and the mode conversion signal generated by the control system 103 switches the working mode of the cooling system 10 by adjusting the position of the internal valve core of the three-way valve.

[0061] See also Figure 3The cooling system 10 also includes: a return water system 21, which is arranged outside the unit of the server cluster and is connected to the water circulation system 102, and is used to purify the water recovered from the water collecting tank 204. The return water system 21 is connected to the water supply system 101, and the water supply system 101 is also used to transport the clean water purified by the return water system 21 to the water circulation system 102.

[0062] In some embodiments of the present disclosure, the control system 103 is also used to generate a water replenishment signal when the water level in the water collecting tank 204 is lower than the water level threshold. The water replenishment signal is used to start the water supply system 101 to transport external clean water into the water collecting tank 204 and stop discharging water from the water collecting tank 204, thereby achieving timely water replenishment of the water collecting tank and ensuring the continuity of spraying.

[0063] See also above Figure 2 and Figure 3 The cooling system 10 also includes a three-way valve 208. The first water supply pipeline 201 and the second water supply pipeline 202 (the first water supply pipeline 201 and the second water supply pipeline 202 are part of the water supply pipeline) are respectively connected to one end of the three-way valve 208, and the other end of the three-way valve 208 is connected to the nozzle 203. The cooling system 10 also includes: a return water system 21 connected to the first water supply pipeline 201. A drain valve 209 can be set on the first water supply pipeline 201. When the drain valve 209 is opened, the water in the first water supply pipeline 201 can be discharged to the return water system 21.

[0064] See also above Figure 2 During the execution of the present invention, the working mode of the cooling system 10 can be switched by adjusting the position of the internal valve core of the three-way valve. The three-way valve can be an electric three-way valve. Thus, the three-way valve can adjust the position of the internal valve core under the control of the central processing unit.

[0065] For example, when the water collection tank 204 of the water circulation system 102 is started to provide water for the spraying device 1021, the three-way valve is controlled by the water tank liquid level combined with the water supply control logic of the cooling system 10. When the water level of the water collection tank 204 is lower than the water level threshold, the three-way valve supplies water in the direction A, but not in the direction B. At this time, the drain valve can be kept closed. When the water level of the water collection tank 204 reaches the upper limit of water replenishment, the water replenishment into the water collection tank 204 is stopped. At this time, the three-way valve does not supply water in the directions A and B, and the drain valve is still kept closed. The sewage valve is closed. In addition, the water quality of the water collecting tank 204 can be detected at any time mentioned above. If it is detected that the water quality of the water collecting tank 204 does not meet the water quality requirements, a recovery signal is generated. The recovery signal is used to stop the water collecting tank 204 from providing water for spraying to the spraying device 1021, and control the water in the water collecting tank 204 to be discharged to the return water system 21, and then adjust the position of the valve core inside the three-way valve to control the external clean water to be delivered to the spraying device 1021. In other words, the three-way valve does not supply water in direction A, but supplies water in direction B.

[0066] When the water in the water collecting tank 204 is controlled to be discharged to the water return system 21, the water in the water collecting tank 204 can be discharged in time.

[0067] That is to say, when it is detected that the water quality of the water collecting tank 204 does not meet the water quality requirements, the water supply in direction A can be stopped, the water pump of the unit can be stopped, the three-way valve is switched to the water supply in direction B for spraying, and the sewage valve of the water collecting tank 204 is opened (the method of opening the sewage valve of the water collecting tank 204 can be a manual switching mode, or it can be automatically switched by the unit body according to the dirtiness value, and there is no restriction on this), so that the water collecting tank 204 no longer stores water, and the water sprayed in direction B is discharged to the return water system 21. When the unit does not need to spray, the three-way valves in directions A and B are not opened.

[0068] Among them, the outdoor air quality, the outdoor air inlet filter pressure difference and other conditions can be monitored. When it is determined that the sewage treatment can be stopped at this time based on the outdoor air quality, the outdoor air inlet filter pressure difference and other conditions, the controller can generate a stop sewage treatment instruction and control the sewage valve to close according to the stop sewage treatment instruction. Alternatively, it can also be manually switched back to normal mode. When it is detected that the user manually controls the switch back to normal mode, a water replenishment signal can be generated when the water level in the water collecting tank 204 is less than the water level threshold. The water replenishment signal is used to start the water supply system 101 to transport external clean water to the water collecting tank 204 and stop discharging the water from the water collecting tank 204. That is to say, the A direction pipeline is controlled to supply water to the water collecting tank 204, and the unit water pump is used to supply water to the nozzle for spraying. The direction of the three-way valve is open in direction A and closed in direction B. Figure 2 204-2011-2012 shown in provide spray water to 203.

[0069] For example, the position of the valve core inside the three-way valve is adjusted to transport the external clean water to the spray device 1021, and provide spray water to the nozzle in the spray device 1021. That is to say, the three-way valve supplies water in the direction of B and does not supply water in the direction of A. At this time, the drain valve can be opened to link the return water system 21, and the return water system 21 is used to purify the water discharged from the water collecting tank 204, and the purified water is recovered into the water storage tank arranged outside the unit body. In the process of linking the return water system 21 to discharge the water in the water collecting tank 204, it can also be detected whether a water replenishment signal is received. If a water replenishment signal is received, the water in the water collecting tank 204 is stopped from being discharged to the return water system 21, and the A direction pipeline is controlled to replenish water to the water collecting tank 204, and water is supplied to the nozzle for spraying through the unit water pump. The direction of the three-way valve is open in the A direction and closed in the B direction. At this time, the drain valve can be closed, and the water circulation system 102 of the unit body is switched back to provide spray water to the spray device 1021.

[0070] By configuring each water supply pipeline to be connected to one end of the three-way valve 208, and the other end of the three-way valve 208 to be connected to the nozzle 203, the position of the valve core inside the three-way valve can be adjusted to switch the working mode. The implementation is simple and will not bring excessive hardware modification costs. In addition, better control effects can be obtained, the control processing logic is simplified, and the sensitivity of the control logic execution is guaranteed.

[0071] By configuring the return water system 21 connected to the water collecting tank 204, a drain valve 209 can be set on the first water supply pipeline 201. When the drain valve 209 is opened, the water in the water collecting tank 204 can be discharged to the return water system 21.
