Detailed Implementation

[0043] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0044] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

Therefore, they should not be construed as limitations of this application.

[0046] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] The inventors of this application have learned that data center liquid cooling removes heat from electronic devices such as servers or switches using liquid instead of air. The liquid carries the heat to the cooling distribution unit, forming a loop. The cooling distribution unit uses cooling water to dissipate the heat from the liquid into the air via a primary water pump, a dry cooler, or a cooling tower. In some cases, a cooling tower or dry cooler alone cannot fully meet the heat dissipation requirements (the required cooling water temperature is relatively low, such as 10-22°C), especially in summer when outdoor environments cannot meet these requirements, necessitating the addition of chillers. Such liquid cooling heat exchange schemes require multiple components in addition to the cooling distribution unit, including a primary water pump, a dry cooler, a cooling tower, and sometimes even a chiller, to achieve liquid cooling. This results in complex designs and large sizes of liquid cooling equipment in data center liquid cooling solutions.

[0048] Based on the above research, this application provides a liquid cooling cold source device and a liquid cooling control method, which can optimize the liquid cooling cold source device and its liquid cooling control method, and achieve a simpler and more intelligent liquid cooling method.

[0049] This application provides a liquid-cooled cold source device. For example... Figure 1 As shown, the liquid-cooled cold source equipment may include: a housing, a dry cooler 110 installed in the housing, a cooling fan 120, a spray head 130, and an air conditioning system 140.

[0050] The housing is provided with an outwardly extending return water inlet 150 and a cooling water outlet 160. The cooling circulating water can enter the liquid cooling source equipment from the return water inlet 150 and then flow out from the cooling water outlet 160, during which time it is cooled in the liquid cooling source equipment.

[0051] In this embodiment, the water return port 150 on the housing, the dry cooler 110, and the air conditioning system 140 are connected through the first regulating valve 170.

[0052] Optionally, the first regulating valve 170 can be a first three-way regulating valve; the first three-way regulating valve includes a first valve port 171, a second valve port 172 and a third valve port 173 respectively.

[0053] The return water port 150 is connected to the first valve port 171, the second valve port 172 is connected to the input end of the dry cooler 110, and the third valve port 173 is connected to the air conditioning system 140.

[0054] By controlling the opening and closing of each valve port of the first three-way regulating valve, the connection of various devices can be realized to adjust the flow path of the cooling circulating water.

[0055] In this embodiment, the cooling water outlet 160 on the housing, the dry cooler 110, and the air conditioning system 140 are connected through the second regulating valve 180.

[0056] Optionally, the second regulating valve 180 can be a second three-way regulating valve; the second three-way regulating valve includes a fourth valve port 181, a fifth valve port 182 and a sixth valve port 183.

[0057] By controlling the opening and closing of each valve port of the second three-way regulating valve, the connection of various devices can be realized to adjust the flow path of cooling circulating water.

[0058] The fourth valve port 181 is connected to the output end of the dry cooler 110, the fifth valve port 182 is connected to the air conditioning system 140, and the sixth valve port 183 is connected to the cooling water outlet 160.

[0059] like Figure 1 As shown, the spray head 130 and the cooling fan 120 are positioned above the dryer 110. The input end of the spray head 130 is connected to the second regulating valve 180.

[0060] To improve the smoothness of cooling water circulation, a booster pump can be installed at the valve port to pressurize the cooling water and improve its circulation.

[0061] Optionally, a first booster pump (not shown) may be installed at the first valve port 171. The first booster pump is used to pressurize the cooling circulating water.

[0062] Optionally, a second pressurizing pump 190 may be provided at the sixth valve port 183, wherein the second pressurizing pump 190 is used to pressurize the cooling circulating water.

[0063] In this embodiment, the air conditioning system 140 may include an evaporator 141; the input end of the evaporator 141 is connected to the third valve port 173; and the output end of the evaporator 141 is connected to the fifth valve port 182.

[0064] In this embodiment, the air conditioning system 140 may further include a condenser 142; the condenser 142 is disposed between the dry cooler 110 and the spray head 130.

[0065] The condenser 142 can be affected by the spray head 130 and the cooling fan 120. The cooling circulating water sprayed by the spray head 130 will pass through the condenser 142 before falling back to the dry cooler 110. When the air conditioning system 140 is working, the condenser 142 is sprayed by the cooling circulating water, which accelerates the heat dissipation of the air conditioning system 140.

[0066] In this embodiment, the air conditioning system 140 may further include a compressor 143; the compressor 143 is disposed inside the housing. This arrangement allows for a more compact housing space.

[0067] For example, such as Figure 1 As shown, the compressor 143 can be installed between the evaporator 141 and the condenser 142.

[0068] The liquid cooling source device in this embodiment may further include a temperature monitoring device installed in one or more locations within the housing for monitoring the temperature of the cooling circulating water.

[0069] A first temperature monitoring device 161 can be installed at the cooling water outlet 160 to monitor the outlet temperature of the cooling circulating water.

[0070] The air conditioning system 140 may also be equipped with a second temperature monitoring device, which includes two temperature monitoring devices, respectively located at the inlet and outlet of the cooling circulating water of the evaporator 141. The devices monitor the inlet water temperature at the inlet of the cooling circulating water of the evaporator 141 and the outlet water temperature at the outlet of the cooling circulating water. The second temperature monitoring device can monitor the temperature difference between the inlet and outlet water temperatures of the cooling circulating water of the evaporator 141 to monitor the cooling effect of the air conditioning system. At the same time, when the first temperature monitoring device 161 fails, the outlet water temperature monitored by the second temperature monitoring device can be used as backup reference data for subsequent liquid cooling control methods.

[0071] Of course, depending on the actual needs, more temperature monitoring devices can be installed in this liquid cooling cold source equipment. For example, a temperature monitoring device can also be installed at the water return port 150 on the shell.

[0072] The liquid-cooled cold source equipment provided in this application integrates the dry cooler 110, cooling fan 120, spray head 130, and air conditioning system 140 into a single housing, thereby simplifying the internal design of the cold source equipment and reducing the overall footprint of the liquid-cooled equipment. By integrating all the devices into a single housing and implementing integrated control, evaporative cooling is fully utilized, extending the natural cooling time and maximizing energy savings, while also allowing for adjustable water temperature output.

[0073] This application also provides a liquid cooling control method, which can be applied to liquid-cooled cold source equipment. For example... Figure 2 As shown, the liquid cooling control method may include the following steps.

[0074] Step 210: Monitor the outlet temperature of the cooling circulating water of the liquid-cooled cold source equipment.

[0075] If the outlet water temperature is not greater than the first set temperature, then step 230 is executed; if the outlet water temperature is greater than or equal to the first set temperature, then step 250 is executed after step 230 is executed; if the outlet water temperature is greater than or equal to the second set temperature, then step 270 is executed after steps 230 and 250 are executed.

[0076] For example, the outlet temperature of the cooling circulating water can be monitored by a first temperature monitoring device 161 installed at the cooling water outlet 160. For instance, during the operation of the liquid cooling source equipment, the first temperature monitoring device 161 can read the outlet water temperature at specified intervals to dynamically adjust the liquid cooling method according to the outlet water temperature.

[0077] Step 230: Start the dry cooler of the liquid cooling source equipment so that the cooling circulating water can be naturally cooled by passing through the dry cooler.

[0078] After the dry cooler 110 is started, the flow path of the cooling circulating water is set to return water port 150, dry cooler 110, and cooling water outlet 160. This allows the cooling circulating water to be cooled at the dry cooler 110.

[0079] In this embodiment, the cooling circulating water can be cooled at the dry cooler 110 by switching the passages of the first regulating valve 170 and the second regulating valve 180.

[0080] For example, the dry cooler 110 of the liquid cooling source device can be cooled by cooling circulating water by connecting the first valve port 171 and the second valve port 172 of the first three-way regulating valve of the liquid cooling source device, and connecting the fourth valve port 181 and the sixth valve port 183 of the second three-way regulating valve that controls the liquid cooling source device.

[0081] In this embodiment, after the dry cooler is started, the outlet water temperature of the cooling circulating water of the liquid-cooled cold source equipment can continue to be monitored.

[0082] Step 250: Start the cooling fan of the liquid-cooled cold source equipment so that the cooling circulating water is cooled by the cooling fan at the dry cooler.

[0083] After the cooling fan 120 is started, the cooling circulating water can be cooled by the cooling fan 120 at the dry cooler 110. When the outlet water temperature is relatively high, the cooling rate can be increased through dual cooling, so that the outlet water temperature can reach a lower temperature.

[0084] In this embodiment, after the cooling fan is started, the outlet temperature of the cooling circulating water of the liquid-cooled cold source equipment can continue to be monitored.

[0085] Step 270: Start the air conditioning system of the liquid-cooled cold source equipment so that at least a portion of the cooling circulating water is cooled by the air conditioning system.

[0086] The second set temperature is greater than the first set temperature.

[0087] In this embodiment, after the air conditioning system is started, the outlet temperature of the cooling circulating water of the liquid-cooled cold source equipment can continue to be monitored.

[0088] When the outlet water temperature reaches the second set temperature, it indicates that the dry cooler 110 and cooling fan 120 can no longer meet the cooling requirements of the circulating water, and the air conditioning system 140 can be further activated. At this time, the passages of the first regulating valve 170 and the second regulating valve 180 are switched so that the cooling circulating water is cooled by the air conditioning system 140.

[0089] Optionally, after the air conditioning system 140 is started, some cooling circulating water can enter the air conditioning system 140, and some cooling circulating water can be cooled by the dry cooler 110. For example, the greater the difference between the outlet water temperature and the second set temperature, i.e., the higher the outlet water temperature, the more cooling circulating water can enter the air conditioning system 140. In this case, when the air conditioning system 140 is turned on, some cooling circulating water can exist in the condenser 142, and some cooling circulating water can also exist in the dry cooler 110. The cooling circulating water in both the condenser 142 and the dry cooler 110 can be cooled simultaneously by the spray head 130. Cooling the cooling circulating water through dual devices improves the cooling efficiency.

[0090] For example, taking the first regulating valve 170 and the second regulating valve 180 as both being three-way regulating valves, by connecting the first valve port 171 and the third valve port 173 of the first three-way regulating valve of the liquid cooling source device, and connecting the fifth valve port 182 and the sixth valve port 183 of the second three-way regulating valve controlling the liquid cooling source device, the air conditioning system 140 of the liquid cooling source device is started to cool the cooling circulating water.

[0091] The flow path of the cooling circulating water is the return water inlet 150 of the liquid cooling cold source equipment, the air conditioning system 140, and the cooling water outlet 160, so that the cooling circulating water is cooled by the air conditioning system 140.

[0092] Optionally, if the outlet water temperature is not greater than the difference between the second set temperature and the set difference, the air conditioning system 140 is turned off. In one example, the second set temperature can be 30°C, and the set temperature difference can be 2°C, so the difference between the second set temperature and the set difference is 28°C. When the outlet water temperature is not greater than 28°C, the air conditioning system 140 can be turned off. Of course, the values ​​of the second set temperature and the set temperature difference mentioned above are merely illustrative. Depending on the actual application scenario, different values ​​can be selected for the second set temperature and the set temperature difference.

[0093] To prevent the air conditioning system 140 from frequently shutting down or starting when the outlet water temperature is equal to the second set temperature, a setting difference can be set. The air conditioning system 140 will only be shut down when the outlet water temperature is no greater than the second set temperature minus the setting difference, thereby improving the stability of the operation of the air conditioning system 140.

[0094] For example, the setting difference can be set as needed, such as 1℃, 2℃, 3℃, etc.

[0095] During the start-up of the air conditioning system 140, the outlet water temperature can be monitored periodically. If the outlet water temperature is not greater than the second set temperature minus the set difference, the air conditioning system 140 is shut down, and the passages of the first regulating valve 170 and the second regulating valve 180 are switched back, so that the cooling circulating water is cooled by the dry cooler 110 again.

[0096] It is understandable that as the outlet temperature of the cooling circulating water gradually increases, cooling can be achieved gradually through steps 230, 250, and 270. As the outlet temperature of the cooling circulating water gradually decreases, the air conditioning system activated in step 270 and the cooling fan activated in step 250 can be gradually shut down.

[0097] By dynamically adjusting the start and stop of the air conditioning system 140 in the above manner, the cooling mode of the cooling circulating water can be dynamically adjusted, and the operation of each component in the integrated liquid cooling cold source equipment can be dynamically controlled, achieving more effective liquid cooling on the basis of energy saving.

[0098] In this embodiment, step 250 may include adjusting the rotation speed of the cooling fan 120 by the difference between the outlet water temperature and the first set temperature.

[0099] The larger the difference, the higher the speed of the cooling fan 120; the smaller the difference, the lower the speed of the cooling fan 120.

[0100] The larger the difference, the higher the outlet water temperature, which requires more energy to achieve cooling. Therefore, the higher the speed of the cooling fan 120, the more efficient the cooling can be.

[0101] If the cooling fan 120 reaches its maximum speed during this period, it indicates that using only the cooling fan 120 is insufficient to meet the cooling requirements of the circulating water, and therefore, more comprehensive cooling methods are needed. Based on this, if... Figure 3 As shown, after step 250, the following steps may also be included: step 261, monitoring the speed of the cooling fan; if the speed of the cooling fan 120 is greater than the speed threshold, step 262, starting the spray head.

[0102] In this embodiment, after step 270 is executed, if the cooling fan 120 is in the start state, the start or stop of the spray head can be adaptively adjusted according to the speed of the cooling fan 120.

[0103] For example, the spray head 130 can be activated by opening the valve of the spray head 130.

[0104] After the spray head 130 is started, the cooling circulating water can first enter the dry cooler 110 and exit from the outlet of the dry cooler 110. Then, it flows through the sixth valve port 183 of the second regulating valve 180 to the outlet. Before flowing out of the outlet, part of the cooling circulating water is diverted to the spray head 130. The cooling circulating water diverted to the spray head 130 will flow through the condenser 142 and the dry cooler 110 in the form of water droplets, further carrying away the heat from the condenser 142 and the dry cooler 110, thus accelerating the cooling of the cooling circulating water.

[0105] In this embodiment, if the speed of the cooling fan 120 decreases, for example, if the speed of the cooling fan 120 is lower than the speed threshold, the spray head 130 can be turned off.

[0106] To avoid frequent starting and stopping of the shower head 130, a buffer value can be set to reduce the frequency of starting and stopping of the shower head 130.

[0107] For example, when the speed of the cooling fan 120 is lower than the difference between the speed threshold and the buffer value, the spray head 130 is then shut down.

[0108] In this embodiment, after the new cooling water circulation loop is formed after the spray head 130 is activated, if there is a loss of cooling water, and when the amount of cooling water loss reaches the set water volume, new cooling water can be added to the liquid cooling source device from outside the liquid cooling source device to keep the cooling water volume sufficient.

[0109] The set water volume can be set as needed. For example, the set water volume can be determined according to the actual size of the liquid cooling source equipment, or it can be determined according to the volume of cooling circulating water circulating in the liquid cooling source equipment.

[0110] For example, the larger the actual size of the liquid cooling source equipment, the larger the set water volume can be; the smaller the actual size of the liquid cooling source equipment, the smaller the set water volume can be.

[0111] For example, the larger the volume of cooling water circulating in the liquid-cooled cold source equipment, the larger the set volume; conversely, the smaller the volume of cooling water circulating in the liquid-cooled cold source equipment, the smaller the set volume. For instance, the set volume could be one-tenth, one-eighth, or the same amount of cooling water.

[0112] By using the above-mentioned liquid cooling control method, the working conditions of each component in the liquid cooling cold source equipment can be adjusted adaptively by fully considering the real-time situation of the outlet water temperature, so as to achieve more effective liquid cooling control and regulate the cooling circulating water in the liquid cooling system.
