DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the implementation of the application described here, for example, can be implemented in an order other than those illustrated or described here. In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way.

[0044] As mentioned in the background technology: In traditional data centers, low-power cabinets are usually cooled by room-level precision air conditioners to remove the heat generated by the cabinets.

[0045] However, as the power of cabinets continues to increase, room-level precision air conditioners have gradually become unable to cope with the cooling requirements of high-power cabinets.

[0046] This is because with the rapid rise in computing power demand and the rapid development of technology, the current single cabinets in data centers with 5KW or less are obviously not suitable for the widespread application of current GPU servers in the face of increasingly complex and large computing tasks. Especially in fields such as artificial intelligence, big data analysis, and deep learning that require extremely high computing power, the limitations of such low-power cabinets are becoming more and more prominent. Therefore, the transition from low-power cabinets to high-power cabinets is imminent. This is not only a key step to improve data processing capabilities and efficiency, but also an inevitable choice to adapt to future digital development trends. For example, in the field of autonomous driving, massive amounts of real-time data need to be quickly processed and analyzed. Cabinets below 5KW cannot meet the high-intensity computing requirements of GPU servers, resulting in computing delays and inaccurate results.

[0047] Among them, when the precision air conditioner cannot meet the refrigeration requirements, it is necessary to replace the precision air conditioner and install equipment that meets the refrigeration requirements (such as row air conditioners). Therefore, the computer room needs to be rectified. How to control the construction difficulty, cost control and impact on the normal operation of the data center of the computer room rectification is the main problem to be solved at present.

[0048] In order to solve the technical problems raised above, the present application provides an air conditioning piping system and a thermal management system for a data center, wherein the air conditioning piping system includes: a water supply pipe in a machine room, a water return pipe in a machine room, a water distributor and a pressure detection device. The water supply pipe in the machine room and the water return pipe in the machine room are connected to the water inlet and outlet of the inter-row air conditioner through the water distributor, so that the installation of the inter-row air conditioner can be realized. Compared with the precision air conditioner, the inter-row air conditioner has a better cooling effect, thereby ensuring the heat dissipation effect of the cabinet after the power is increased. In addition, the water supply pipe in the machine room and the water return pipe in the machine room adopt the water inlet and outlet pipe of the original precision air conditioner, which can reduce the difficulty and cost of the machine room renovation. By setting a pressure detection device, the water pressure in the water supply branch and the water return branch can be detected and recorded in real time, so as to facilitate the comparison and analysis with the preset measurement values ​​of the inter-row air conditioner to ensure the energy efficiency of the inter-row air conditioner.

[0049] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0050] refer to Figure 1 An embodiment of the present application discloses an air conditioning piping system for a data center. The data center includes a computer room and at least one unit arranged in the computer room. Each unit includes a plurality of cabinet devices arranged side by side and a plurality of row air conditioners embedded between the cabinet devices. The row air conditioners have a water inlet and a water outlet.

[0051] The air conditioning pipeline system includes: a machine room water supply pipe 100, a machine room water return pipe 200, a water distributor 300 and a pressure detection device 400.

[0052] The water distributor 300 includes a water supply pipe 310 and a return pipe 320, wherein the water supply pipe 310 includes a water supply main pipe 311 and a water supply branch pipe 312, the water supply main pipe 311 is connected to the machine room water supply pipe 100, a plurality of water supply branches 312 are provided, and the water supply branches 312 correspond to the inter-row air conditioners one by one, one end of the water supply branch pipe 312 is connected to the water supply main pipe 311, and the other end of the water supply branch pipe 312 is connected to the water inlet of the corresponding inter-row air conditioner. Exemplarily, there are 4 water supply branches 312, and the 4 water supply branches 312 are all connected to the water supply main pipe 311. Of course, the number of water supply branches 312 can be selected according to actual design needs, and some water supply main pipes 311 extend along the arrangement direction of the plurality of water supply branches 312. The end of the water supply main pipe 311 in the extension direction can be set as a closed structure to prevent the internal liquid from leaking out. The water supply main 311 and the water supply branch 312 can be connected through a three-way pipe fitting. Of course, in the relevant field, they can also be connected through other methods. The embodiment of the present application does not make specific restrictions on this part of the structure.

[0053] The return water pipe 320 includes a return water main pipe 321 and a return water branch 322. The return water main pipe 321 is connected to the machine room return water pipe 200. The return water branch 322 is set to multiple, and the return water branch 322 corresponds to the inter-row air conditioner one by one. One end of the return water branch 322 is connected to the return water main pipe 321, and the other end of the return water branch 322 is connected to the water outlet of the corresponding inter-row air conditioner. Exemplarily, there are 4 return water branches 322, and the 4 return water branches 322 are all connected to the return water main pipe 321. It should be noted here that the number of return water branches 322 should correspond to the number of water supply branches 312. In this way, the uniform pressure in the pipeline is ensured. Of course, the number of return water branches 322 can be selected according to actual design needs, and some return water main pipes 321 extend along the arrangement direction of multiple return water branches 322. The end of the return water main pipe 321 in the extension direction can be set as a closed structure to prevent the internal liquid from leaking out.

[0054] The return water main 321 and the return water branch 322 can be connected through a three-way pipe fitting. Of course, in the relevant field, they can also be connected through other methods. The embodiment of the present application does not make specific restrictions on this part of the structure.

[0055] A pressure detection device 400 is provided on each of the water supply branch 312 and the water return branch 322 . The pressure detection device 400 is used to detect the chilled water pressure in the water supply branch 312 and / or the water return branch 322 .

[0056] Exemplarily, a plurality of units are arranged in the machine room, each unit includes a plurality of cabinets and a plurality of row-to-row air conditioners, and each cabinet corresponds to each row-to-row air conditioner one by one.

[0057] Exemplarily, the water supply pipe 100 and the water return pipe 200 of the computer room adopt the water inlet pipe and the water outlet pipe of the original precision air conditioner. That is, when the precision air conditioner cannot meet the heat dissipation of the cabinet after the power is increased, the precision air conditioner needs to be dismantled and only the water inlet pipe and the water outlet pipe of the precision air conditioner are retained. In order to reduce the construction difficulty of replacing the inter-row air conditioner, the water supply pipe 100 and the water return pipe 200 of the computer room adopt the water inlet pipe and the water outlet pipe of the original precision air conditioner.

[0058] Exemplarily, the number of water supply branches 312 and return water branches 322 corresponds to the number of inter-row air conditioners. The chilled water in the machine room water supply pipe 100 enters the water supply branch 312 through the water supply main pipe 311, and then the chilled water is transported to the inter-row air conditioners by the water supply branch 312. After heat exchange in the inter-row air conditioners, the chilled water is transported to the return water main pipe 321 through the return water branch 322, and then discharged through the machine room return water pipe 200, thereby supplying chilled water to the inter-row air conditioners.

[0059] Exemplarily, the pressure detection device 400 may be a pressure gauge. A plurality of pressure gauges are provided. Each water supply branch 312 and each water return branch 322 may be provided with a pressure gauge to obtain the water pressure in the water supply branch 312 and the water return branch 322 .

[0060] By adopting the above technical solution, by setting the machine room water supply pipe 100, the machine room return pipe 200, the water distributor 300 and the pressure detection device 400, the machine room water supply pipe 100 and the machine room return pipe 200 are connected to the water inlet and outlet of the inter-row air conditioner through the water distributor 300, so that the installation of the inter-row air conditioner can be realized. Compared with the precision air conditioner, the inter-row air conditioner has a better cooling effect, thereby ensuring the heat dissipation effect of the cabinet after the power is increased.

[0061] In addition, the water supply pipe 100 and the water return pipe 200 of the machine room adopt the water inlet pipe and the water outlet pipe of the original precision air conditioner, which can reduce the difficulty and cost of the machine room renovation.

[0062] By setting the pressure detection device 400, the water pressure in the water supply branch 312 and the return branch 322 can be detected and recorded in real time, so as to facilitate comparison and analysis with the preset measurement values ​​of the inter-row air conditioner to ensure the energy efficiency of the inter-row air conditioner. Exemplarily, the preset measurement values ​​of the inter-row air conditioner can be the standard pressure value or pressure fluctuation range set by the inter-row air conditioner according to the actual scene design needs, or the pressure value or pressure fluctuation range that can achieve the best energy efficiency of the inter-row air conditioner. When the water pressure in the water supply branch 312 and the return branch 322 detected by the pressure detection device 400 does not match the preset measurement values ​​of the inter-row air conditioner, the water supply branch 312 and the return branch 322 can be maintained and optimized in time to ensure the working state of the water supply branch 312 and the return branch 322, thereby ensuring the working energy efficiency of the inter-row air conditioner.

[0063] In some embodiments, the machine room has a floor, a floor assembly is disposed on the upper side of the floor, and a static pressure chamber is defined between the floor assembly and the floor.

[0064] The unit is arranged on the upper side of the floor assembly, and the water supply branch 312 and the water return branch 322 are arranged in the static pressure cabin and connected to the corresponding inter-row air conditioners.

[0065] Illustratively, a space is provided between the floor assembly and the ground to form a static pressure chamber.

[0066] For example, the original precision air-conditioning room also has a static pressure cabin, which has an air inlet duct and an air outlet duct. When the precision air-conditioning is replaced with an inter-row air-conditioning, the original static pressure cabin is used, and the water supply branch 312 and the return water branch 322 can be respectively inserted into the air inlet duct and the air outlet duct. This not only reduces the construction difficulty, but also prevents the water supply branch 312 and the return water branch 322 from entering the room when they are damaged, thereby damaging the cabinet.

[0067] By adopting the above technical solution, a static pressure cabin is set up, and the water supply branch 312 and the return water branch 322 are passed through the static pressure cabin, which not only facilitates the installation of the water supply branch 312 and the return water branch 322, but also prevents the water flowing out from entering the computer room when the water supply branch 312 and the return water branch 322 are damaged, thereby preventing damage to the cabinet.

[0068] In some embodiments, the computer room includes a hot channel and a cold channel located on opposite sides of the unit, the inter-row air conditioner is configured to discharge cold air into the cold channel, and the cabinet equipment is configured to discharge hot air into the hot channel.

[0069] The water supply manifold 312 is located in the portion of the plenum corresponding to the cold aisle.

[0070] The water return branch 322 is located in the portion of the plenum corresponding to the hot channel.

[0071] By adopting the above technical solution, a hot channel and a cold channel are set up. The cold channel is used for cold air to pass through, so that the cold air cools the cabinet equipment. The hot channel is used for hot air to pass through, so that the hot air in the cabinet equipment is transported, thereby separating the cold air from the hot air, avoiding the hot air from affecting the cooling effect of the cold air, and ensuring the cooling effect of the inter-row air conditioner on the cabinet equipment.

[0072] In addition, the water supply branch 312 is arranged in the part of the static pressure cabin corresponding to the cold channel, and the return water branch 322 is arranged in the part of the static pressure cabin corresponding to the hot channel, so as to avoid a large heat exchange between the cold air and the hot air between the water supply branch 312 and the return water branch 322, thereby ensuring the temperature of the chilled water supplied by the water supply branch 312 and avoiding the return water branch 322 from affecting the temperature of the cold air.

[0073] In some embodiments, the air conditioning piping system of the data center further includes: a control device, which is used to control the operating state of the water distributor 300, and the operating state includes: the chilled water flow of at least one of the water supply main 311, the water supply branch 312, the return water main 321 and the return water branch 322.

[0074] Exemplarily, the control device is arranged in a control cabinet in a machine room.

[0075] Exemplarily, flow regulating valves are provided on the water supply main 311, the water supply branch 312, the return water main 321 and the return water branch 322, and the flow regulating valves are configured to control the flow of the water supply main 311, the water supply branch 312, the return water main 321 and the return water branch 322. For example, the flow regulating valve is a solenoid valve, and the control device is communicatively connected to the solenoid valve.

[0076] By adopting the above technical solution and setting a control device, the chilled water flow of at least one of the water supply main 311, the water supply branch 312, the return water main 321 and the return water branch 322 can be controlled, thereby facilitating the control of the heat dissipation effect of the inter-row air conditioner.

[0077] In some embodiments, the pressure detection device 400 is in communication connection with the control device, and the control device is configured to control the flow state of the chilled water in the water supply branch 312 and / or the water return branch 322 according to the detection result of the pressure detection device 400. Specifically, the flow state includes: flow size, flow velocity size, and on-off state.

[0078] By adopting the above technical solution, when the pressure detection device 400 detects that the pressure value in the water supply branch 312 is small, the flow rate and flow rate in the water supply branch 312 can be increased by the control device, thereby increasing the pressure value in the water supply branch 312. When the pressure detection device 400 detects that the pressure in the water supply branch 312 is large, the flow rate and flow rate in the water supply branch 312 can be reduced by the control device, thereby reducing the pressure value in the water supply branch 312. Of course, when the pressure detection device 400 detects that the pressure value in the return water branch 322 is small, the flow rate and flow rate in the return water branch 322 can be increased by the control device, thereby increasing the pressure value in the return water branch 322. When the pressure detection device 400 detects that the pressure in the return water branch 322 is large, the flow rate and flow rate in the return water branch 322 can be reduced by the control device, thereby reducing the pressure value in the return water branch 322.

[0079] Furthermore, when the pressure in the water supply branch 312 and / or the water return branch 322 is too high, the circulation of the chilled water may be interrupted to quickly reduce the pressure value in the water supply branch 312 and / or the pressure value in the water return branch 322 .

[0080] In some embodiments, the air conditioning piping system of the data center further includes:

[0081] A temperature detection device 500 is provided on each water supply branch 312 and each water return branch 322 . The temperature detection device 500 is used to detect the temperature of the chilled water in the water supply branch 312 and / or the water return branch 322 .

[0082] The temperature detection device 500 is communicatively connected to the control device, and the control device is configured to control the flow state of the chilled water in the water supply branch 312 and / or the water return branch 322 according to the detection result of the temperature detection device 500, and the flow state includes: flow size, flow velocity size, and on-off state.

[0083] Exemplarily, the temperature detection device 500 may be a temperature sensor. A plurality of temperature sensors are provided. Each of the water supply branch 312 and the water return branch 322 may be provided with a temperature sensor to obtain the temperature inside the water supply branch 312 and the water return branch 322 .

[0084] By adopting the above technical solution, when the temperature detection device 500 detects that the temperature of the water supply branch 312 is high and the temperature in the return water branch 322 is high, the control device controls the flow rate and flow velocity in the water supply branch 312 and the return water branch 322 to increase to ensure the cooling effect of the inter-row air conditioner. When the temperature detects that the temperature of the water supply branch 312 is low and the temperature in the return water branch 322 is low, the heat dissipation power of the inter-row air conditioner is large and there is a certain amount of power waste. Therefore, the control device can be used to control the flow rate and flow velocity in the water supply branch 312 and the return water branch 322 to decrease, thereby reducing the heat dissipation power of the inter-row air conditioner and reducing energy waste.

[0085] Furthermore, when the temperature in the water supply branch 312 and / or the water return branch 322 is too high, the circulation of the chilled water may be interrupted to quickly reduce the temperature in the water supply branch 312 and / or the temperature in the water return branch 322 .

[0086] In some embodiments, the air conditioning pipe system of the data center further includes: a thermal insulation component, which is coated on the outside of at least one of the water supply main 311 , the water supply branch 312 , the return water main 321 and the return water branch 322 .

[0087] Exemplarily, the water supply main 311 , the water supply branch 312 , the water return main 321 and the water return branch 322 are all provided with heat insulation components.

[0088] By adopting the above technical solution and providing insulation components, the degree of heat exchange between the water supply main 311, the water supply branch 312, the return water main 321 and the return water branch 322 and the outside world when transporting water can be reduced, thereby reducing energy loss and ensuring the cooling effect of the inter-row air conditioner.

[0089] In some embodiments, the thermal insulation component includes thermal insulation wool.

[0090] By adopting the above technical solution and setting up thermal insulation cotton, not only can the degree of heat exchange between at least one of the water supply main 311, the water supply branch 312, the return water main 321 and the return water branch 322 and the outside world when transporting cooling water be reduced, but also the cost of the air conditioning pipe system of the data center can be reduced.

[0091] In some embodiments, the air conditioning piping system of the data center further includes: a differential pressure balancing valve 600, which is disposed on the return pipe 321. It should be noted that, according to actual design requirements, a plurality of return pipes 321 may be connected to a return pipe 200 of a computer room, and the plurality of return pipes 321 may be return pipes 321 in the air conditioning piping system of the data center disposed at different locations. For example, in actual settings, multiple data centers may be disposed on the same floor, and data centers may be disposed on different floors.

[0092] By adopting the above technical solution and setting a pressure differential balancing valve 600, the pressure between multiple return water mains 321 is ensured to be stable, thereby avoiding unstable flow and abnormal equipment operation due to pressure fluctuations, reducing unnecessary energy consumption, and affecting the normal operation of the inter-row air conditioners, so as to improve the operating efficiency of the entire system.

[0093] The embodiment of the present application also discloses a thermal management system for a data center, including a device body and an air conditioning pipeline system for a data center in any of the above embodiments. The air conditioning pipeline system is arranged on the device body, and the device body of the thermal management system for a data center is a prior art in the relevant field, and the embodiment of the present application does not limit the specific structure of the device body.

[0094] Among them, the structure and principle of the air conditioning pipeline system of the data center have been clearly explained in the above embodiments, and will not be elaborated here one by one.

[0095] The various embodiments or implementation methods in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referenced to each other.

[0096] It should be noted that the embodiments represented by "one embodiment", "an embodiment", "an exemplary embodiment", "some embodiments", etc. mentioned in the specification may include specific features, structures or characteristics, but not every embodiment may include the specific features, structures or characteristics.
