Description

Technical Field

[0001] This application relates to liquid cooling technology, and more particularly to a liquid-cooled cabinet, equipment and system. Background Technology

[0002] With the increasing demand for computing power and the continuous improvement of power density in data centers, traditional air cooling technology not only fails to meet the requirements of the "dual carbon" policy, but also becomes increasingly difficult to meet the heat dissipation needs of high-load servers in data centers. The transformation of data center heat dissipation solutions from air cooling to liquid cooling is becoming a new trend in the industry.

[0003] Immersion liquid cooling is a commonly used liquid cooling technology. The principle of immersion liquid cooling is to inject coolant into a server rack (tank) to immerse the server in the coolant. The continuous circulation of the coolant removes heat dissipated by the server. However, in this method, when new coolant enters the liquid-filled rack, the flow rate decreases sharply, and a large amount of fluid flows through the low-heat areas of the server, leaving limited flow through the core heat-generating areas. This results in the system's cooling capacity not being fully utilized, leading to low heat exchange efficiency. Utility Model Content

[0045] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] With the increasing demand for computing power and the continuous improvement of power density in data centers, traditional air cooling technology not only fails to meet the requirements of the "dual carbon" policy, but also becomes increasingly difficult to meet the heat dissipation needs of high-load servers in data centers. The transformation of data center heat dissipation solutions from air cooling to liquid cooling is becoming a new trend in the industry.

[0048] Immersion liquid cooling is a commonly used liquid cooling technology. Figure 1 This is a structural schematic diagram of a liquid cooling device in related technologies. For example... Figure 1 As shown in the related technology, the device may include a liquid-cooled cabinet 11 and an inlet pipe 12 disposed at the bottom of the liquid-cooled cabinet 11. The liquid-cooled cabinet 11 contains a server 00. Coolant enters the interior of the liquid-cooled cabinet 11 through the inlet pipe 12 and is sprayed upwards onto the server 00 to achieve the purpose of cooling the server 00.

[0049] However, in the above method, when the new coolant enters the liquid-filled cabinet, the flow rate will decrease sharply, and a large amount of fluid will flow through the low-heat area of ​​the server, while the flow through the core heat-generating area will be limited, resulting in the system's cooling capacity not being fully utilized and the heat exchange efficiency being low.

[0050] Based on this, the present invention provides a liquid-cooled cabinet, a liquid-cooling device and a liquid-cooling system to increase the flow of coolant in the cabinet and improve heat exchange efficiency.

[0051] The technical solutions of this application are illustrated below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0052] This application provides a liquid-cooled cabinet. Figure 2 This is a schematic diagram of the structure of the liquid-cooled cabinet provided in the embodiments of this application, as shown below. Figure 2 As shown, the liquid-cooled cabinet 200 includes: a cabinet body 210, a first liquid inlet pipe 220, and a liquid outlet pipe 230, wherein:

[0053] The cabinet body 210 has a chamber for loading servers and containing coolant.

[0054] The first liquid inlet pipe 220 is used to inject coolant, and the first liquid inlet pipe 220 is provided with at least one first liquid inlet 221; the first liquid inlet 221 is used to connect to the liquid guide pipe 01 of the server 00, the liquid guide pipe 01 of the server 00 is in communication with the interior of the server 00, and the coolant flows into the interior of the server 00 through the liquid guide pipe 01 and flows out of the server 00 to the chamber.

[0055] The first liquid inlet 221 is provided with an opening and closing component 2211, which is configured such that when the liquid guide tube 01 is inserted into the first liquid inlet 221, the first liquid inlet 221 is opened; and when the liquid guide tube 01 is pulled out from the first liquid inlet 221, the first liquid inlet 221 is closed.

[0056] The outlet pipe 23 is located inside the chamber and communicates with the interior of the chamber, and is used to discharge the coolant inside the chamber.

[0057] It should be noted that the liquid-cooled cabinet 20 in this embodiment can be a horizontal cabinet, a vertical cabinet, or a wall-mounted cabinet, and there are no restrictions on it.

[0058] The following explanation uses a horizontal server rack as an example:

[0059] In practical implementation, the first inlet pipe 220 introduces coolant, which then enters the liquid guide pipe 01 of the server 00 connected to the first inlet port 211, and is precisely delivered to the interior of the server 00 by the liquid guide pipe 01. For example, the liquid guide pipe 01 can be connected to a heat-generating component 02 inside the server 00. The heat-generating component can be flexibly selected according to actual production needs; for example, it can be a server component that generates significant heat, or a core component of the server such as the CPU. Therefore, the coolant can first be used to cool the interior of the server 00, and then flow out from inside the server 00 to the cavity to dissipate heat from the exterior of the server 00, thus fully utilizing the system's cooling capacity and improving heat exchange efficiency.

[0060] The heating element 02 can be immersed in liquid cooling technology, and the end of the liquid guide pipe 01 can be provided with a spray nozzle for spraying liquid onto the heating element 02. Alternatively, the heating element 02 can be cooled by a cold plate liquid cooling technology, and the liquid guide pipe 01 can be connected to the cold plate of the heating element 02.

[0061] To avoid ineffective coolant flow, only the first inlet 221 with the inserted coolant tube 01 is opened, while the other first inlets 221 are closed. In some technologies, an electric valve or solenoid valve can be installed at the first inlet 221. Controlling the valve to open or close the first inlet 221 results in low efficiency in installing the server 00 into the liquid-cooled cabinet 200. In one possible implementation, an opening / closing component 2211 can be provided at the first inlet 221. The opening / closing component 2211 is configured to close or open the first inlet 221. When the coolant tube 01 is inserted into the first inlet 221, the opening / closing component 2211 slides away from the first inlet 221 under pressure, thereby automatically opening the first inlet 221. When the coolant tube 01 is pulled out from the first inlet 221, the opening / closing component 2211 returns to a position close to the first inlet 221, and the first inlet 221 automatically closes. In this way, the first liquid inlet 221 can be automatically opened when the liquid guide tube 01 is inserted, and automatically closed at other times, avoiding ineffective flow of coolant, effectively improving the efficiency of installing server 00, and making full use of the system's cooling capacity.

[0062] In this embodiment, the coolant is a non-conductive fluid medium. For example, the coolant can be synthetic oil or fluorinated liquid products.

[0063] In one possible implementation, such as Figure 2 As shown, the opening and closing assembly 2211 includes an elastic element 2211a and a baffle 2211b, wherein:

[0064] One end of the elastic element 2211a is connected to the baffle 2211b, and the other end of the elastic element 2211a is connected to the first liquid inlet pipe 221; the projection of the first liquid inlet 221 toward the baffle 2211b is inside the baffle 2211b.

[0065] When the liquid guide tube 01 is inserted into the first liquid inlet 211, the baffle 2211b slides away from the first liquid inlet 211, and the elastic element 2211a is compressed to open the first liquid inlet 211; when the liquid guide tube 01 is pulled out from the first liquid inlet 211, the elastic element drives the baffle 2211b to slide toward the first liquid inlet 211 to close the first liquid inlet 211.

[0066] In practical implementation, when no liquid guide tube 01 is inserted into the first liquid inlet 221, the elastic element 2211a is in a balanced state, and the baffle 2211b is tightly attached to the first liquid inlet 221, thereby closing the first liquid inlet 221; when a liquid guide tube 01 is inserted into the first liquid inlet 221, the baffle 2211b slides away from the first liquid inlet 221, and the elastic element 2211a is in a compressed state, thereby automatically opening the first liquid inlet 221 and connecting the liquid guide tube 01 with the first liquid inlet tube 220; when the liquid guide tube 01 is pulled out from the first liquid inlet 221, the baffle 2211b is reset under the elastic force of the elastic element 2211a, thereby automatically closing the first liquid inlet 221, saving operation time.

[0067] The liquid cooling cabinet 200 described above uses a rigid material for the liquid guide tube 01, which allows the liquid guide tube 01 to effectively apply pressure to the elastic member 2211a when inserted into the first liquid inlet 221, thereby compressing the elastic member 2211a and realizing the automatic opening of the first liquid inlet 221.

[0068] In one possible implementation, such as Figure 2 As shown, the liquid-cooled cabinet 200 also includes at least one guide member 240;

[0069] The first liquid inlet 221 is provided on the guide 240 in a one-to-one correspondence. The guide 240 and the outer wall of the first liquid inlet pipe 220 together form a receiving cavity. The first liquid inlet 221 and the first liquid inlet pipe 220 are both connected to the receiving cavity.

[0070] The opening and closing assembly 2211 is disposed in the receiving cavity; the other end of the elastic member 2211a is connected to the outer wall of the first liquid inlet pipe 220, and the baffle 2211b slides along the length direction of the guide member 240 to close or open the first liquid inlet 221.

[0071] It should be noted that the extension direction of the guide member 240 is perpendicular to the extension direction of the first liquid inlet pipe 220, and the first liquid inlet 221 is located on the side of the guide member 240 away from the first liquid inlet pipe 220. By setting the guide member 240 to limit the movement position of the baffle 2211b, so as to keep it stable, the first liquid inlet 221 can be opened or closed accurately.

[0072] In one possible implementation, such as Figure 2 As shown, the liquid-cooled cabinet also includes a support frame 250;

[0073] The support frame 250 is installed in the chamber. The support frame 250 is used to load the server 00 and limit the loaded server 00 so that the liquid guide tube 01 of the server 00 loaded onto the support frame 250 is inserted into the first liquid inlet 221.

[0074] Specifically, the support frame 250 is provided with at least one fixing part, each fixing part being used to load a server 00 and limit the loaded server 00.

[0075] In practical implementation, after the server 00 is installed on the fixed part of the support frame 250, the liquid guide tube 01 of the server 00 can automatically align with the first liquid inlet 221. Under the pressure of the liquid guide tube 01, the opening and closing component 2211 slides away from the first liquid inlet 221, so that the liquid guide tube 01 can be directly and blindly inserted into the first liquid inlet 221 without manual alignment, which effectively improves the installation efficiency of the server 00.

[0076] For example, the fixing part can be a mounting slot. In one possible implementation, the support frame 250 has a mounting slot for insertion with the server 00.

[0077] In a specific implementation, the mounting slot can be opened relative to the position of the first liquid inlet 221, so that when the server 00 is placed in the mounting slot, the liquid guide tube 01 of the server 00 can be aligned with the first liquid inlet 221 in a direction perpendicular to the bottom surface of the liquid cooling cabinet 200, thereby enabling the liquid guide tube 01 to be blindly inserted into the first liquid inlet 221.

[0078] In one possible implementation, such as Figure 2 As shown, the support frame 250 is equipped with a pressure-sensitive device 251, which is used to sense whether a server 00 is mounted on the support frame 250.

[0079] In the aforementioned liquid-cooled cabinet 200, all the coolant first enters the liquid guide pipe 01 of the server 00 through the first liquid inlet 221, dissipates heat from the heat-generating components 02 inside the server 00, and then flows into the cavity to cool the exterior of the server 00. To prevent the coolant in the cavity from being unable to effectively cool the server 00, some coolant can be introduced into the server's interior while some coolant is directly introduced into the cavity.

[0080] Figure 3 This is a schematic diagram of another liquid-cooled cabinet provided as an embodiment of this application. Figure 3 As shown, in one possible implementation, at least one second liquid inlet 222 is also provided on the wall of the first liquid inlet pipe 220, and the liquid cooling cabinet 200 also includes at least one first guide pipe 260.

[0081] For each first guide tube 260, one end of the first guide tube 260 is connected to a second liquid inlet 222, and the other end of the first guide tube 260 is used to spray coolant into the cavity.

[0082] It should be noted that the second liquid inlet 222 corresponds one-to-one with the first guide pipe 260. One end of each first guide pipe 260 is connected to a corresponding second liquid inlet 222, and the other end of the first guide pipe 260 can be equipped with a spray head to spray coolant into the cavity. The first liquid inlet 221 is a one-way valve type, and the second liquid inlet 222 is a direct liquid inlet. The first liquid inlet 221 and the second liquid inlet 222 can be staggered, so that the coolant can be evenly delivered to the gaps between the server 00 within the cavity through the second liquid inlet 222 for effective cooling of the server. In practical applications, other methods can also be used to open the first liquid inlet 221 and the second liquid inlet 222; these are not limited here.

[0083] The aforementioned liquid-cooled cabinet 200 delivers a portion of the coolant directly into the server 00 through the first inlet 221 to precisely dissipate heat from the heat-generating components 02; and delivers a portion of the coolant into the external cavity of the server 00 through the second inlet 222 to cool the server 00 as a whole. This fully utilizes the cooling capacity of the coolant and effectively reduces the temperature of the server 00.

[0084] Figure 4 This is a structural schematic diagram of another liquid-cooled cabinet provided in an embodiment of this application. (See attached diagram.) Figure 4 As shown, in one possible implementation, the liquid-cooled cabinet 200 further includes: a second liquid inlet pipe 270 and at least one second guide pipe 280;

[0085] At least one third inlet 271 is provided on the wall of the second inlet pipe 270;

[0086] For each second guide tube 280, one end of the second guide tube 280 is connected to a third liquid inlet 271, and the other end of the second guide tube 280 is used to spray coolant into the cavity.

[0087] It should be noted that the third liquid inlet 271 and the second guide pipe 280 are in a one-to-one correspondence. One end of each second guide pipe 280 is connected to a corresponding third liquid inlet 271, and the other end of the second guide pipe 280 can be equipped with a spray head to spray coolant into the chamber. Among them, the third liquid inlet 271 is a direct liquid inlet.

[0088] The aforementioned liquid-cooled cabinet 200 delivers a portion of the coolant directly into the server 00 through the first inlet pipe 220 to precisely dissipate heat from the heat-generating components 02; and delivers a portion of the coolant into the external cavity of the server 00 through the second inlet pipe 270 to cool the server 00 as a whole. This fully utilizes the cooling capacity of the coolant and effectively reduces the temperature of the server 00.

[0089] Figure 5This is a structural schematic diagram of another liquid-cooled cabinet provided in an embodiment of this application. (See attached diagram.) Figure 1 , Figure 5 As shown, the first liquid inlet pipe 220 is located at the bottom of the cabinet body 210;

[0090] The liquid outlet pipe 230 is located at the bottom or top of the cabinet body 210.

[0091] In a specific implementation, when the liquid outlet pipe 230 is located at the bottom of the cabinet body 210, the first liquid inlet pipe 220 can be located on the inner wall of the first side near the cabinet body 210, and the liquid outlet pipe 230 can be located on the inner wall of the second side near the cabinet body 210, wherein the inner walls of the first side and the second side are arranged opposite to each other. The liquid outlet pipe 230 can be located at the bottom or top of the cabinet body 210 according to actual needs, so that the coolant is sprayed from the bottom of the cabinet body 210.

[0092] To facilitate better coolant drainage, in one possible implementation, with the chamber containing coolant, the outlet pipe is submerged in the coolant. Coolant can then enter the outlet on the outlet pipe and drain out.

[0093] Based on the same concept, embodiments of this application also provide a liquid cooling device. Figure 6 This is a schematic diagram of the structure of the liquid cooling device provided in an embodiment of this application. Figure 6 As shown, the liquid cooling device 60 includes a heat exchange unit 610, a fluid distributor 620, and at least one liquid cooling cabinet 200, wherein:

[0094] The output end of the heat exchange unit 610 is connected to the input end of the fluid distributor 620, and the input end of the heat exchange unit 610 is connected to the output end of the fluid distributor 620. The heat exchange unit 610 is used to exchange heat and cool the coolant, and deliver the cooled coolant to the fluid distributor 620.

[0095] The distribution output end of the fluid distributor 620 is connected to the first liquid inlet pipe 220 of the liquid cooling cabinet 200, and the distribution input end of the fluid distributor 620 is connected to the liquid outlet pipe 230 of the liquid cooling cabinet 200. The fluid distributor 620 is used to perform a flow splitting operation on the coolant and deliver the split coolant to the corresponding liquid cooling cabinet 200.

[0096] It should be noted that in the embodiments of this application, the heat exchange unit 610 and the liquid cooling cabinet 200 can be an integrated unit or a separate unit, and there is no limitation on them here.

[0097] In a specific implementation, the primary side of the heat exchanger 610 is connected to a cooling device (not shown in the figure). For example, the cooling device can be a cooling tower, a dry cooler, a chiller, etc. The output end of the secondary side of the heat exchanger 610 serves as the output end of the heat exchange unit 610 and is connected to the input end of the fluid distributor 52. It is also connected to the output end of the temperature sensor 517 to deliver coolant to the fluid distributor 52. The input end of the secondary side of the heat exchanger 511 is connected to the output end of the cooling pump 512, the input end of the adjustable valve 513, and the output end of the system filter 514 through different shut-off valves 518. It is also connected to the output end of the temperature sensor 517 to input the coolant after heat exchange. The heat exchanger 511 is specifically used for heat exchange between the primary and secondary sides.

[0098] In one possible implementation, the heat exchange unit 610 includes a heat exchanger 611 and a water pump 612;

[0099] The output end of heat exchanger 611 is connected to the input end of fluid distributor 620, the input end of water pump 612 is connected to the output end of fluid distributor 620, and the input end of heat exchanger 611 is connected to the output end of water pump 612.

[0100] Heat exchanger 611 is used for heat exchange and cooling of coolant;

[0101] Water pump 612 is used to pressurize the coolant input to heat exchanger 611.

[0102] In a specific implementation, the primary side of the heat exchanger 610 is connected to a cooling device (not shown in the figure) and a water pump 612. For example, the cooling device can be a cooling tower, a dry cooler, a chiller, etc. The output end of the secondary side of the heat exchanger 610 serves as the output end of the heat exchange unit 610 and is connected to the input end of the fluid distributor 620 to deliver coolant to the fluid distributor 620. The heat exchanger 611 is specifically used for heat exchange between the primary and secondary sides. Multiple water pumps 612 can be connected in parallel. A first shut-off valve 613 can be installed at the input end of each water pump 612, and a one-way valve 614 can be installed at the output end of each water pump 612. The one-way valve 614 is used to prevent coolant backflow; the output end of the one-way valve 614 is connected to a second shut-off valve 615. The water pump 612 is specifically used to pressurize the coolant input to the heat exchanger 611. A water pump can also be installed at the input end of the secondary side of the heat exchanger 610; this is not limited.

[0103] like Figure 2 and Figure 6 As shown, in one possible implementation, when the pressure-sensitive device 251 senses that the support frame 250 is not carrying the server 00, the water pump 612 is turned off or operates at minimum speed.

[0104] In practical implementation, the pressure-sensitive device 251 can be used to determine whether the support frame 250 in the liquid-cooled cabinet 200 is loaded with a server 00. When the pressure-sensitive device 251 senses that the support frame 250 is not carrying a server 00, the water pump 612 is turned off or runs at its minimum speed, thereby realizing automatic control of the water pump, which is beneficial for saving energy and reducing waste of resources.

[0105] In one possible implementation, the water pump 612 is further configured to operate at a first rotational speed corresponding to the current total number of servers, based on a preset correspondence between the total number of servers loaded in at least one liquid-cooled cabinet 200 and the rotational speed; wherein the total number of servers is negatively correlated with the resistance within the first liquid inlet pipe 220 and / or the second liquid inlet pipe 270.

[0106] In a specific implementation, the distribution output of the fluid distributor 620 is connected to the first inlet pipe 220 of at least one liquid-cooled cabinet 200. The first inlet port 221 on the first inlet pipe 220 is open when the first inlet pipe 01 of the server 00 is inserted, and closed when the first inlet pipe 01 is not inserted. If the total number of servers loaded in at least one liquid-cooled cabinet 200 is small, most of the first inlet ports 221 are closed, the total outlet area of ​​the first inlet pipe 220 is smaller, the resistance inside the first inlet pipe 220 is greater, and the pressure inside the pipe is greater. If the total number of servers loaded in at least one liquid-cooled cabinet 200 is large, most of the first inlet ports 221 are open, the total outlet area of ​​the first inlet pipe 220 is larger, the resistance is smaller, and the pressure inside the pipe is smaller. Therefore, the total number of servers loaded in at least one liquid-cooled cabinet 200 is negatively correlated with the resistance inside the first inlet pipe 220 and / or the second inlet pipe 270. To maintain sufficient pressure in the pipe, the pump speed can be preset to correspond to different total number of servers. The initial pump speed is determined based on the actual number of servers currently installed. The pump speed is higher when the total number of servers is small and lower when the total number of servers is large. This allows for accurate control of the pump speed, maintaining sufficient pipe pressure while reducing energy consumption, thereby effectively improving the product's energy efficiency ratio.

[0107] In one possible implementation, a pressure sensor 616 is also provided at the input or output end of the water pump 612. The water pump 612 is also used to adjust the first rotation speed according to the pressure detected by the pressure sensor 616 and to operate at the adjusted second rotation speed.

[0108] In practice, after determining the first speed of the water pump based on the total number of servers currently installed, the first speed can be further adjusted based on the pressure before or after the pump detected by the pressure sensor 616. This allows for more accurate control of the water pump operation and effectively maintains sufficient pressure in the system pipeline.

[0109] In one possible implementation, a temperature sensor is installed inside the liquid-cooled cabinet 60 or server 00, and the water pump 612 is also used to operate at a corresponding speed based on the temperature detected by the temperature sensor.

[0110] In a specific implementation, the water pump 612 can adjust its speed based on the pressure detected by the pressure sensor 616 at the input or output end of the water pump 612 and / or the temperature detected by the temperature sensor inside the liquid-cooled cabinet 60 or server 00, thereby ensuring sufficient flow of coolant and effectively dissipating heat from the server 00.

[0111] Based on the same concept, embodiments of this application also provide a liquid cooling system, including the liquid cooling device as described above and at least one server.

[0112] The specific implementation of this liquid cooling system can be found in the liquid cooling equipment and liquid cooling cabinets described above, and will not be repeated here.
