[0001] Cross-reference to Related Applications

[0002] The present disclosure claims priority to Chinese Patent Application No. 202411335686.X filed on September 24, 2024 in China, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of data center heat dissipation, in particular to a data center multi-connection heat dissipation pipeline system. BACKGROUND

[0004] With the rapid development of digital economy, data centers gradually evolve into intelligent computing centers. Compared with data centers, intelligent computing centers have stronger computing power resources and higher power density, and accordingly, higher power density heat dissipation demand. To solve the high power density heat dissipation demand, the application of liquid cooling technology is becoming increasingly common. The current mainstream liquid cooling technology is divided into cold plate liquid cooling and immersion liquid cooling. The cold plate liquid cooling system is simple, reliable and efficient, and can efficiently utilize natural cold sources through high-temperature coolant contact heat exchange, saving overall energy consumption of data centers, and has been gradually widely applied in data centers.

[0005] It should be noted that the heat dissipation object of the cold plate liquid cooling technology is high-power heat dissipation components such as central processing units (CPUs), graphics processing units (GPUs) and the like in servers, while memory, hard disk and other heat dissipation components still need to be cooled by air cooling. In related technologies, for the liquid cooling and air cooling heat dissipation of data centers, the pipeline systems required by the two are prone to conflict with each other, resulting in difficult layout of the pipeline systems of the two.

[0094] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of this disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0095] The data center multi-connection heat dissipation pipeline system provided by the embodiments of the present disclosure comprises a cabinet group, a liquid cooling pipeline system and an air cooling pipeline system. Both sides of the cabinet group are formed with installation channels, and the installation channels comprise hot channels and cold channels. The hot channels and the cold channels are arranged on both sides of the cabinet group. The cabinet group comprises a plurality of liquid cooling cabinets 11 arranged in a row and a plurality of inter-row air conditioners 12. The inter-row air conditioners 12 are arranged between the liquid cooling cabinets 11. The liquid cooling pipeline system comprises a liquid cooling pipeline subsystem. The liquid cooling pipeline subsystem is arranged corresponding to the hot channels. The liquid cooling pipeline system introduces a liquid cooling pipeline subsystem into the hot channels at a first end, so as to provide circulating cooling liquid for the liquid cooling cabinets 11 corresponding to the hot channels. The air cooling pipeline system comprises an air cooling pipeline subsystem 300. The air cooling pipeline subsystem 300 is arranged corresponding to the cold channels. The air cooling pipeline system introduces an air cooling pipeline subsystem 300 into the cold channels at a second end, so as to provide circulating chilled water for the inter-row air conditioners 12 corresponding to the cold channels. The first end and the second end are two ends of the installation channels which are away from each other. That is, when only one cabinet group is arranged, the two sides of the cabinet group are the hot channels and the cold channels, that is, one side of the cabinet group is the liquid cooling pipeline subsystem, and the other side is the air cooling pipeline subsystem 300. The two do not interfere with each other, and the introduction directions are away from each other, which avoids the pipeline layout conflict problem and facilitates the internal maintenance of the machine room and the free arrangement of the pipeline outside the machine room.

[0096] Of course, in other embodiments, a plurality of cabinet groups can be arranged at intervals in the machine room, as described below. FIG. 1 is a data center multi-connection heat dissipation pipeline system. Referring to FIG. 1, the data center multi-connection heat dissipation pipeline system comprises a plurality of cabinet groups, a liquid cooling pipeline system and an air cooling pipeline system. Both sides of each cabinet group are formed with installation channels, that is, the plurality of cabinet groups are arranged at intervals. The plurality of installation channels comprise hot channels and cold channels. The hot channels and the cold channels are arranged alternately, that is, in the arrangement direction of the plurality of installation channels, if the first installation channel is a hot channel, the second installation channel is a cold channel, and the third installation channel is a hot channel, and so on. It should be noted that in order to distinguish the installation positions of the liquid cooling pipeline subsystem and the air cooling pipeline subsystem 300, the hot channels are used to install the liquid cooling pipeline subsystem, and the cold channels are used to install the air cooling pipeline subsystem 300. Since the cooling liquid transported by the liquid cooling pipeline subsystem is generally higher in temperature than the chilled water transported by the air cooling pipeline subsystem 300, the hot channels are only compared with the cold channels, and are not limited to the temperature levels in the hot channels and the cold channels.

[0097] The cabinet group comprises a plurality of liquid cooling cabinets 11 arranged in a row and a plurality of inter-row air conditioners 12, the plurality of inter-row air conditioners 12 are respectively arranged between the plurality of liquid cooling cabinets 11, for example, one inter-row air conditioner 12 is arranged between every one or two liquid cooling cabinets 11, so that the inter-row air conditioner 12 performs air cooling heat dissipation on the hardware devices in the liquid cooling cabinet 11.

[0098] The liquid cooling pipeline system comprises at least two liquid cooling pipeline subsystems, each liquid cooling pipeline subsystem corresponds to a hot channel, the liquid cooling pipeline system introduces one liquid cooling pipeline subsystem into one hot channel at a first end, to provide circulating cooling liquid for the plurality of liquid cooling cabinets 11 corresponding to the hot channel. The liquid cooling cabinet 11 is provided with a matching cold energy distribution unit, the liquid cooling pipeline system is connected at the cold energy distribution unit of the liquid cooling cabinet 11, through the functional combination of the subsystems, the requirements of reasonable cold energy distribution, space intensive layout, and convenient installation and maintenance in the data center can be realized, and the development needs of the data center combined with the liquid cooling technology to evolve to high-density computing power can be met.

[0099] The air cooling pipeline system comprises at least two air cooling pipeline subsystems 300, each air cooling pipeline subsystem 300 corresponds to a cold channel, the air cooling pipeline system introduces one air cooling pipeline subsystem 300 into the cold channel at a second end, to provide circulating chilled water for the plurality of inter-row air conditioners 12 corresponding to the cold channel, wherein the first end and the second end are two ends away from the installation channel.

[0100] It can be understood that the plurality of cabinets arranged in a row are arranged in the machine room, the liquid cooling pipeline system and the air cooling pipeline system can be respectively connected to the two sides of the machine room, that is, the first end and the second end corresponding to the installation channel are connected separately, to avoid pipeline layout conflict. The liquid cooling pipeline system and the air cooling pipeline system are connected to the cold source side and the machine room side, to provide liquid cooling and air cooling heat dissipation services for the liquid cooling cabinet 11, and can realize the pipeline system of multiple connections and expansion.

[0101] The data center multi-connected liquid cooling pipe system provided by the embodiments of the present disclosure divides the multiple installation channels formed between the multiple groups of cabinets into hot channels and cold channels, that is, the multiple installation channels are divided into hot channels and cold channels arranged alternately, the hot channels are used for installing the liquid cooling pipe system, and the cold channels are used for installing the air cooling pipe system, and the pipe layouts of the two do not conflict. Each liquid cooling pipe subsystem is introduced into the hot channel at a first end, used for providing circulating cooling liquid for the liquid cooling cabinet 11, and each air cooling pipe subsystem 300 is introduced into the cold channel at a second end, used for providing circulating chilled water for the inter-row air conditioner 12. The first end and the second end are two ends of the data center multi-connected liquid cooling pipe system that face away from each other. In this way, the liquid cooling pipe system and the air cooling pipe system are reasonably arranged through double-side introduction and staggered arrangement. The two sides of each group of cabinets are the hot channel and the cold channel, that is, each group of cabinets is convenient for connecting the liquid cooling pipe system and the air cooling pipe system, and the problem of space layout conflict of the air cooling and liquid cooling pipes can be solved, and the internal maintenance of the machine room and the external pipe connection of the machine room can be freely arranged.

[0102] The data center multi-connected liquid cooling pipe system provided by the embodiments of the present disclosure can increase or decrease the number of cabinet rows according to the size of the machine room, and adapt to the corresponding functions of the subsystems, thereby meeting the arrangement requirements of the data center multi-connected liquid cooling pipe system. The spacing between each group of cabinets is consistent, and the space utilization rate of the machine room is high.

[0103] In an embodiment, the air cooling refrigeration form can be changed to other forms including but not limited to the air cooling fluorine pump inter-row air conditioner 12, the heat pipe backboard, the indirect evaporative cooling air conditioner, and the like. The air cooling pipe system is correspondingly adjusted to a freon refrigerant pipe or an air supply channel. The liquid cooling and air cooling pipe space layout in the present disclosure can also be used, and is also within the protection scope of the present disclosure.

[0104] As shown in FIG. 2, in an embodiment, the liquid cooling pipe subsystem includes a liquid cooling water supply main pipe 21, a liquid cooling water return main pipe 22, multiple liquid cooling water supply branch pipes, and multiple liquid cooling water return branch pipes. The liquid cooling water supply main pipe 21 is introduced into the hot channel at a first end and extends along the extension direction of the hot channel. The liquid cooling water return main pipe 22 is introduced into the hot channel at a first end and extends along the extension direction of the hot channel. The liquid cooling water supply branch pipes are arranged corresponding to the liquid cooling cabinet 11, and the liquid cooling cabinet 11 is connected to the liquid cooling water supply main pipe 21 through the liquid cooling water supply branch pipes. The liquid cooling water return branch pipes are arranged corresponding to the liquid cooling cabinet 11, and the liquid cooling cabinet 11 is connected to the liquid cooling water supply main pipe 21 through the liquid cooling water return branch pipes.

[0105] It can be understood that the liquid cooling water supply main pipe 21 and the liquid cooling water return main pipe 22 are used as main lines to connect external cooling sources to supply cooling liquid to the liquid cooling cabinet 11 in the corresponding heat channel. Specifically, a plurality of liquid cooling water supply branch pipes are connected in the extension direction of the liquid cooling water supply main pipe 21, and one liquid cooling water supply branch pipe can be arranged to correspond to one liquid cooling cabinet 11, or one liquid cooling water supply branch pipe can be arranged to correspond to two liquid cooling cabinets 11. At the same time, a plurality of liquid cooling water return branch pipes are connected in the extension direction of the liquid cooling water return main pipe 22, and one liquid cooling water return branch pipe can be arranged to correspond to one liquid cooling cabinet 11, or one liquid cooling water return branch pipe can be arranged to correspond to two liquid cooling cabinets 11. The liquid cooling water supply branch pipe and the liquid cooling water return branch pipe can be connected through the liquid cooling cabinet 11, so as to supply and return water to the liquid cooling cabinet 11 and provide circulating cooling liquid for heat dissipation.

[0106] In one embodiment, the liquid cooling pipeline subsystem includes two liquid cooling water supply main pipes 21, and a plurality of liquid cooling water supply branch pipes are connected in parallel through the two liquid cooling water supply main pipes 21. In this way, two water supply paths are provided to transmit cooling liquid from the liquid cooling water supply branch pipe to the corresponding liquid cooling cabinet 11, which improves the stability of the cooling liquid transmission, and at the same time, realizes mutual backup of the two liquid cooling water supply main pipes 21. When one of the liquid cooling water supply main pipes 21 needs to be repaired, only the other liquid cooling water supply main pipe 21 can be opened for transmission, realizing online repair and maintenance. It should be noted that in the case of double water supply, the pipeline size and flow rate of the liquid cooling water supply main pipe 21 and the liquid cooling water supply branch pipe can be adjusted according to actual conditions to ensure normal operation of the liquid cooling pipeline subsystem.

[0107] In one embodiment, the liquid cooling pipeline subsystem also includes two liquid cooling water return main pipes 22, and a plurality of liquid cooling water return branch pipes are connected in parallel through the two liquid cooling water return main pipes 22. In order to adapt to the flow rate design of double water supply, the double water return effect is realized through the two liquid cooling water return main pipes 22. Specifically, the two liquid cooling water supply main pipes 21 are used as main lines to provide double water supply effect to the liquid cooling cabinet 11, and after the cooling liquid completes heat dissipation through the liquid cooling cabinet 11, the two liquid cooling water return main pipes 22 are used as main lines to provide double water return effect to the liquid cooling cabinet 11, realizing circulation of the cooling liquid. The double supply and double return structure design is beneficial to improving the transmission efficiency of the cooling liquid, thereby improving the heat dissipation efficiency, and on the other hand, the on-off of the two water supply and return main pipes is controlled respectively to meet the mutual backup of the two water supply and return main pipes, ensuring that the liquid cooling pipeline subsystem realizes online repair and maintenance, that is, one water supply and return main pipe does not affect the normal work of the other water supply and return main pipe, and maintenance does not need to be stopped.

In this way, between the two groups of cabinet banks, it is not necessary to set up a liquid cooling pipeline subsystem for each group of cabinet banks, but the two ends of the liquid cooling double-sided water supply branch pipe 23 are connected with the liquid cooling cabinets 11 on both sides respectively. Specifically, the liquid cooling water supply main pipe 21 extends along the hot aisle, and the liquid cooling double-sided water supply branch pipe 23 is perpendicular to the liquid cooling water supply main pipe 21, so that the two ends of the liquid cooling double-sided water supply branch pipe 23 are connected with the liquid cooling cabinets 11 in the two groups of cabinet banks respectively.

[0121] As shown in FIG. 3, in one embodiment, the liquid cooling pipeline system further comprises a single-side liquid cooling pipeline subsystem 202 located at the installation channel in the edge position, in which the liquid cooling water supply branch pipe comprises a liquid cooling single-side water supply branch pipe 23a and a liquid cooling fifth connecting branch pipe 24a, one end of the liquid cooling single-side water supply branch pipe 23a is connected to one of the liquid cooling water supply trunk pipes 21, and the other end is connected to the liquid cooling cabinets 11 in the cabinet group; the liquid cooling fifth connecting branch pipe 24a is connected to the liquid cooling single-side water supply branch pipe 23a and the other liquid cooling water supply trunk pipe 21.

[0122] It can be understood that the single-side liquid cooling pipeline subsystem 202 can be installed at the installation channel in the edge position, that is, only one side of the single-side liquid cooling pipeline subsystem 202 is placed with the cabinet group, and only one side water supply is needed. Specifically, the liquid cooling water supply trunk pipe 21 extends along the heat channel, the liquid cooling double-side water supply branch pipe 23 extends perpendicularly to the liquid cooling water supply trunk pipe 21 and towards the side direction where the cabinet group is placed, so that the liquid cooling single-side water supply branch pipe 23a is connected to the liquid cooling cabinets 11 in the cabinet group.

[0124] It can be understood that the liquid cooling single-side water return branch pipe 26a is arranged corresponding to the liquid cooling single-side water supply branch pipe 23a, specifically, the liquid cooling water return trunk pipe 22 extends along the heat channel, and the liquid cooling single-side water return branch pipe 26a extends perpendicularly to the liquid cooling water return trunk pipe 22, so that one end of the liquid cooling single-side water return branch pipe 26a is connected to the liquid cooling cabinets 11 in the cabinet group. In order to realize double water return effect, one end of the liquid cooling single-side water return branch pipe 26a is connected to one of the liquid cooling water return trunk pipes 22, and the other end is connected to the other liquid cooling water return trunk pipe 22 through the liquid cooling sixth connecting branch pipe 27a.

[0132] In a specific embodiment, among the plurality of liquid cooling pipe system subsystems of the liquid cooling pipe system, both the single-side liquid cooling pipe subsystem 202 and the double-side liquid cooling pipe subsystem 201 are included, and the single-side liquid cooling pipe subsystem 202 is arranged at the edge position of the installation channel, while the double-side liquid cooling pipe subsystem 201 is arranged at the middle position of the installation channel, according to whether the cabinet group is placed at the double-side installation channel.

[0133] As shown in FIG. 2, an embodiment of the double-side liquid cooling pipe subsystem 201 is described as follows:

[0134] The double-sided liquid cooling pipeline subsystem 201 includes two A and B liquid cooling water supply and return main pipes (i.e., liquid cooling water supply main pipe 21 and liquid cooling water return main pipe 22), and the liquid cooling water supply and return main pipes are provided with a stop valve 1, an electric regulating valve 2, a pressure sensor 3, a temperature sensor 4, a Y-type filter 5 and other components at the cold source side interface, and are connected to an external cold source of a machine room. An exhaust valve 7 is arranged at the end of the main pipe to facilitate the timely discharge of gas in the liquid cooling pipeline system and improve the fluid delivery efficiency. The double liquid cooling water supply main pipe 21 is connected in parallel by multiple liquid cooling water supply branch pipes, and the double liquid cooling water return main pipe 22 is connected in parallel by multiple liquid cooling water return branch pipes. For example, one liquid cooling water supply branch pipe and one liquid cooling water return branch pipe form a set of liquid cooling water supply and return branch pipes to be connected to the same liquid cooling cabinet 11, and a set of water supply and return branch pipes are connected to two liquid cooling cabinets 11 placed face to face, and the liquid cooling cabinet 11 is a cold plate type liquid cooling server cabinet provided with a distributed cooling distribution unit (CDU). It can be understood that for the double-sided liquid cooling pipeline subsystem 201, the number of sets of water supply and return branch pipes corresponds to half of the total number of liquid cooling cabinets 11 in the two-row cabinet group. A plurality of pairs of butterfly valve bodies 29 are arranged on each set of water supply and return branch pipes to control the on-off of the connection between the A and B water supply and return main pipes and the distributed CDU water supply and return interface, so as to satisfy the mutual backup of the A and B liquid cooling water supply and return systems and ensure that the liquid cooling pipeline system can be maintained and repaired online. In addition, the double-sided liquid cooling pipeline subsystem 201 additionally provides two pairs of communication valve groups in each set of liquid cooling water supply and return branch pipes to ensure that when the valve connected to the CDU or the valve connected to the main pipe fails, only the corresponding liquid cooling cabinet 11 can be maintained and repaired online. Since the working fluid of the liquid cooling pipeline subsystem is cooling liquid, its temperature is higher than that of chilled water, so it is not necessary to wrap the pipeline with thermal insulation materials.

[0135] As shown in FIG. 3, an embodiment of the single-sided liquid cooling pipeline subsystem 202 is described as follows:

[0136] The single-sided liquid cooling pipeline subsystem 202 includes two A and B routes of double-supply double-return water main pipes (i.e., liquid cooling water supply main pipe 21 and liquid cooling water return main pipe 22), the liquid cooling water supply and return main pipes are provided with components such as stop valve 1, electric regulating valve 2, pressure sensor 3, temperature sensor 4, Y-type filter 5 and the like at the cold source side interface, and are connected to the external cold source of the machine room. An exhaust valve 7 is arranged at the end of the main pipe to facilitate the timely discharge of gas in the liquid cooling pipeline and improve the fluid delivery efficiency. The double-route liquid cooling water supply main pipe 21 is connected in parallel by multiple liquid cooling water supply branch pipes, the double-route liquid cooling water return main pipe 22 is connected in parallel by multiple liquid cooling water return branch pipes. For example, one liquid cooling water supply branch pipe and one liquid cooling water return branch pipe form a set of liquid cooling water supply and return branch pipes to be connected to the same liquid cooling cabinet 11. One set of liquid cooling water supply and return branch pipes is connected to the liquid cooling cabinet 11 arranged on one side. The number of sets of water supply and return branch pipes corresponds to the number of liquid cooling cabinets 11. The liquid cooling cabinet 11 is a cold plate type liquid cooling server cabinet provided with a distributed CDU (cold distribution unit).

[0137] As shown in FIG. 4, in one embodiment, the air cooling pipeline subsystem 300 includes an air cooling water supply main pipe 31, an air cooling water return main pipe 32, multiple air cooling water supply branch pipes and multiple air cooling water return branch pipes. The air cooling water supply main pipe 31 is introduced into the cold aisle at the second end and extends along the extension direction of the cold aisle. The air cooling water return main pipe 32 is introduced into the cold aisle at the second end and extends along the extension direction of the cold aisle. The air cooling water supply branch pipes are arranged corresponding to the inter-row air conditioners 12. The inter-row air conditioners 12 are connected to the air cooling water supply main pipe 31 through the air cooling water supply branch pipes. The air cooling water return branch pipes are arranged corresponding to the inter-row air conditioners 12. The inter-row air conditioners 12 are connected to the air cooling water supply main pipe 31 through the air cooling water return branch pipes.

[0138] It can be understood that the air cooling water supply main pipe 31 and the air cooling water return main pipe 32 are used as main lines to connect the external cold source to supply cooling liquid to the inter-row air conditioners 12 in the corresponding cold aisle. Specifically, multiple air cooling water supply branch pipes are connected at intervals in the extension direction of the air cooling water supply main pipe 31. One air cooling water supply branch pipe can be arranged to correspond to one inter-row air conditioner 12, or one air cooling water supply branch pipe can be arranged to correspond to two inter-row air conditioners 12. Meanwhile, multiple air cooling water return branch pipes are connected at intervals in the extension direction of the air cooling water return main pipe 32. One air cooling water return branch pipe can be arranged to correspond to one inter-row air conditioner 12, or one air cooling water return branch pipe can be arranged to correspond to two inter-row air conditioners 12. A set of air cooling water supply branch pipes and air cooling water return branch pipes can be connected through the inter-row air conditioner 12, so as to supply and return water to the inter-row air conditioner 12 and provide circulating chilled water for the refrigeration work of the inter-row air conditioner 12.

[0139] In an embodiment, the air cooling pipeline subsystem 300 comprises two air cooling water supply main pipes 31, and multiple air cooling water supply branch pipes are connected in parallel through the two air cooling water supply main pipes 31. In this way, two water supply paths are provided for the air cooling water supply branch pipes to deliver to the corresponding inter-row air conditioners 12, which improves the stability of the chilled water delivery, and meanwhile, realizes mutual backup of the two air cooling water supply main pipes 31, so that when one of the air cooling water supply main pipes 31 needs to be repaired, the other air cooling water supply main pipe 31 can be opened for delivery, realizing online repair and maintenance. It should be noted that in the case of double water supply, the pipeline size and flow rate of the air cooling water supply main pipe 31 and the air cooling water supply branch pipe can be adjusted according to the actual situation to ensure normal operation of the air cooling pipeline subsystem 300.

[0140] In an embodiment, the air cooling pipeline subsystem 300 further comprises two air cooling water return main pipes 32, and multiple air cooling water return branch pipes are connected in parallel through the two air cooling water return main pipes 32. In order to adapt to the flow rate design of double water supply, the double water return effect is realized through the two air cooling water return main pipes 32. Specifically, the two air cooling water supply main pipes 31 are used as the main pipeline to provide double water supply effect for the inter-row air conditioners 12, and after the chilled water is cooled by the inter-row air conditioners 12, the two air cooling water return main pipes 32 are used as the main pipeline to provide double water return effect for the inter-row air conditioners 12, realizing the circulation of the chilled water. The double supply and double return structure design is beneficial to improving the transmission efficiency of the chilled water, thereby improving the cooling efficiency, and on the other hand, the on-off of the two water supply and return main pipes is controlled respectively to meet the mutual backup of the two water supply and return main pipes, ensuring that the air cooling pipeline subsystem 300 realizes online repair and maintenance, that is, the repair and maintenance of one water supply and return main pipe does not affect the normal operation of the other water supply and return main pipe, and there is no need to stop for maintenance.

[0141] In an embodiment, the air cooling pipeline system comprises a double-sided air cooling pipeline subsystem 300, in which the air cooling water supply branch pipe comprises an air cooling double-sided water supply branch pipe 33, an air cooling first connecting branch pipe 34, and an air cooling second connecting branch pipe 35. One end of the air cooling double-sided water supply branch pipe 33 is connected to the inter-row air conditioner 12 in one row of cabinet groups, and the other end is connected to the inter-row air conditioner 12 in another row of cabinet groups. The air cooling first connecting branch pipe 34 connects the air cooling double-sided water supply branch pipe 33 and the air cooling water supply main pipe 31. The air cooling second connecting branch pipe 35 connects the air cooling double-sided water supply branch pipe 33 and the other air cooling water supply main pipe 31.

[0142] It can be understood that the double-sided air-cooled pipeline subsystem 300 can be arranged in the cold aisle where the cabinet groups are arranged on both sides, that is, the double-sided air-cooled pipeline subsystem 300 is arranged on both sides of the cabinet groups, and the air-cooled double-sided water supply branch pipe 33 can simultaneously supply cooling liquid to the inter-row air conditioners 12 in the cabinet groups on both sides. In this way, between the two cabinet groups, one air-cooled pipeline subsystem 300 is not needed for each cabinet group, and the air-cooled double-sided water supply branch pipe 33 can be connected to the inter-row air conditioners 12 on both sides. Specifically, the air-cooled water supply main pipe 31 extends along the cold aisle, and the air-cooled double-sided water supply branch pipe 33 is perpendicular to the air-cooled water supply main pipe 31, so that the two ends of the air-cooled double-sided water supply branch pipe 33 are connected to the inter-row air conditioners 12 in the two cabinet groups. In order to realize double water supply effect, the air-cooled double-sided water supply branch pipe 33 is connected to one of the air-cooled water supply main pipes 31 through the air-cooled first connecting branch pipe 34, and connected to the other air-cooled water supply main pipe 31 through the air-cooled second connecting branch pipe 35.

[0143] In one embodiment, in the double-sided air-cooled pipeline subsystem 300, the air-cooled water return branch pipe includes an air-cooled double-sided water return branch pipe 36, an air-cooled third connecting branch pipe 37, and an air-cooled fourth connecting branch pipe 38. One end of the air-cooled double-sided water return branch pipe 36 is connected to the inter-row air conditioner 12 in one cabinet group, and the other end is connected to the inter-row air conditioner 12 in the other cabinet group. The air-cooled third connecting branch pipe 37 connects the air-cooled double-sided water return branch pipe 36 and the air-cooled water return main pipe 32. The air-cooled fourth connecting branch pipe 38 connects the air-cooled double-sided water return branch pipe 36 and the other air-cooled water return main pipe 32.

[0144] It can be understood that the air-cooled double-sided water return branch pipe 36 is arranged corresponding to the air-cooled double-sided water supply branch pipe 33. Specifically, the air-cooled water return main pipe 32 extends along the cold aisle, and the air-cooled double-sided water return branch pipe 36 is perpendicular to the air-cooled water return main pipe 32, so that the two ends of the air-cooled double-sided water return branch pipe 36 are connected to the inter-row air conditioners 12 in the two cabinet groups. In order to realize double water return effect, the air-cooled double-sided water return branch pipe 36 is connected to one of the air-cooled water return main pipes 32 through the air-cooled third connecting branch pipe 37, and connected to the other air-cooled water return main pipe 32 through the air-cooled fourth connecting branch pipe 38.

[0145] In one embodiment, the two ends of the air-cooled double-sided water supply branch pipe 33 are provided with valve bodies 29 to control the water supply of the inter-row air conditioners 12 on both sides;

[0146] Optionally, the air-cooled first connecting branch pipe 34 is provided with a valve body 29 to control the connection between the air-cooled double-sided water supply branch pipe 33 and one of the air-cooled water supply main pipes 31;

[0147] Optionally, the air-cooled second connecting branch pipe 35 is provided with a valve body 29 to control the connection between the air-cooled double-sided water supply branch pipe 33 and the other air-cooled water supply main pipe 31;

[0148] Optionally, the pipe section between the air-cooled first connecting branch pipe 34 and the air-cooled second connecting branch pipe 35 of the air-cooled double-side water supply branch pipe 33 is provided with a communication valve pair, the communication valve pair includes two valve bodies 29 connected in series, and is used for controlling the on-off of the two air-cooled water supply main pipes 31, realizing mutual backup of the two, realizing online maintenance, and ensuring that when one valve body 29 fails, the other valve body 29 can be closed to realize online maintenance of the failed valve body 29 and improve fault tolerance.

[0149] Optionally, the air-cooled double-side water return branch pipe 36 is provided with a valve body 29 at each end to control the water return of the air conditioner 12 between the two sides.

[0150] Optionally, the air-cooled third connecting branch pipe 37 is provided with a valve body 29 to control the on-off of the air-cooled double-side water return branch pipe 36 and one of the air-cooled water return main pipes 32.

[0151] Optionally, the air-cooled fourth connecting branch pipe 38 is provided with a valve body 29 to control the on-off of the air-cooled double-side water return branch pipe 36 and the other air-cooled water return main pipe 32.

[0152] Optionally, the pipe section between the air-cooled third connecting branch pipe 37 and the air-cooled fourth connecting branch pipe 38 of the air-cooled double-side water return branch pipe 36 is provided with a communication valve pair, the communication valve pair includes two valve bodies 29 connected in series, and is used for controlling the on-off of the two air-cooled water return main pipes 32, realizing mutual backup of the two, realizing online maintenance, and ensuring that when one valve body 29 fails, the other valve body 29 can be closed to realize online maintenance of the failed valve body 29 and improve fault tolerance.

[0153] Optionally, the valve bodies 29 are all butterfly valves.

[0154] In one embodiment, the outer surfaces of the air-cooled water supply main pipes 31, the air-cooled water return main pipes 32, the air-cooled water supply branch pipes, and the air-cooled water return branch pipes are all covered with thermal insulation materials, which can be thermal insulation cotton.

[0155] Please continue to refer to FIG. 4, and the following describes one embodiment of the air-cooled pipe subsystem 300:

[0156] The air-cooled pipeline subsystem 300 is a double-sided air-cooled pipeline subsystem 300, which can select a chilled water system or a freon refrigerant pipeline system according to the form of the air-cooled heat dissipation terminal. Taking the chilled water system with a more complex structure as an example, it includes two A and B routes of double-supply and double-return, a total of four water supply and return main pipes. The air-cooled water supply and return main pipes are provided with stop valves 1, electric regulating valves 2, pressure sensors 3, temperature sensors 4, Y-type filters 5 and other components at the interface with the cold source side, and are connected to the external cold source of the machine room. An exhaust valve 7 is arranged at the end of the main pipe to facilitate the timely discharge of gas in the liquid-cooled pipeline and improve the fluid transmission efficiency. The double air-cooled water supply main pipe 31 is connected in parallel by multiple air-cooled water supply branch pipes, and the double air-cooled water return main pipe 32 is connected in parallel by multiple air-cooled water return branch pipes. One air-cooled water supply branch pipe and one air-cooled water return branch pipe form a set of air-cooled water supply and return branch pipes, and a set of air-cooled water supply and return branch pipes are connected to the ends of the inter-row air conditioners 12 arranged face to face on the left and right two rows of cabinets. The number of air-cooled water supply and return branch pipe groups corresponds to half the number of inter-row air conditioners 12 in the two rows of cabinet groups. Similar to the double-sided liquid-cooled pipeline subsystem 201, multiple pairs of butterfly valves are arranged on each set of water supply and return branch pipes to control the connection of the A and B water supply and return main pipes and the inter-row air conditioners 12 to ensure the backup of the A and B air-cooled water supply and return systems and ensure that the air-cooled pipeline system can be maintained and repaired online. Similarly, the double-sided air-cooled pipeline subsystem 300 additionally provides 2 pairs of communication valve groups in each set of air-cooled water supply and return branch pipes to ensure that when the valve connected to the inter-row air conditioner 12 or the valve connected to the main pipe fails, only the corresponding inter-row air conditioner 12 can be maintained and repaired online. It should be particularly pointed out that since the air-cooled pipeline subsystem 300 transmits and distributes chilled water, the pipeline needs to be wrapped with insulation.

[0157] In an embodiment, the double-sided liquid-cooled pipeline subsystem 201 and the double-sided air-cooled pipeline subsystem 300 have the same structure, and the difference lies in that the external interfaces of the air-cooled pipeline system and the liquid-cooled pipeline system are arranged at the two ends of the machine room, that is, the installation positions of the double-sided liquid-cooled pipeline subsystem and the double-sided air-cooled pipeline subsystem 300 are different. It can be understood that for different installation positions, only the external interfaces of the two are located on both sides, which is reflected in the inconsistency of the installation direction on site. That is, before installation, the double-sided liquid-cooled pipeline subsystem 201 and the double-sided air-cooled pipeline subsystem 300 have the same structure, and thus the present scheme further proposes to normalize, standardize and modularize the liquid-cooled pipeline subsystem and the air-cooled pipeline subsystem 300, thereby realizing prefabrication and greatly reducing the difficulty of on-site installation and improving the reliability of the pipeline.

[0158] Please refer to FIG. 5 to FIG. 8, in an embodiment, the liquid cooling pipeline subsystem and the air cooling pipeline subsystem 300 each include a plurality of pipeline prefabricated modules, the pipeline prefabricated module includes a water supply branch pipe section 53 and a return water branch pipe section 54, the water supply branch pipe section 53 is connected with two water supply elbow pipes arranged at intervals; the return water branch pipe section 54 is connected with two return water elbow pipes arranged at intervals.

[0159] It can be understood that the branch pipe part of the double-sided liquid cooling / air cooling pipeline subsystem 300 can be prefabricated, as shown in FIG. 5 and FIG. 6. At this time, the branch pipe pipeline tee, elbow, valve body 29, interface, etc. are welded with the branch pipe pipeline, and the pressure test is completed in the factory, and the quality verification is completed after the factory is shipped, which greatly improves the pipeline reliability. When installing on site, the prefabricated branch pipe prefabricated module and the dry pipe can be connected by screw thread connection (such as FIG. 5) or flange connection (such as FIG. 6), which can greatly reduce the number of interfaces of each branch pipe installed on site, thereby avoiding complex installation work on site and significantly simplifying the installation difficulty on site.

[0160] Please refer to FIG. 7 and FIG. 8, in an embodiment, the liquid cooling pipeline subsystem and the air cooling pipeline subsystem 300 each include a plurality of pipeline prefabricated modules, the pipeline prefabricated module includes two water supply dry pipe sections 51, a water supply branch pipe section 53, two return water dry pipe sections 52 and a return water branch pipe section 54; the water supply branch pipe section 53 is connected with the two water supply dry pipe sections 51 through two water supply elbow pipes; the return water branch pipe section 54 is connected with the two return water dry pipe sections 52 through two return water elbow pipes.

[0161] Further, a group of water supply and return double-sided liquid cooling / air cooling pipeline branch pipe prefabricated modules and corresponding double water supply and return dry pipes can be prefabricated as a whole, as shown in FIG. 7 and FIG. 8. At this time, the branch pipe pipeline and the tee, elbow, valve, interface connected with the dry pipe can be welded in the factory, and the pressure test is completed in the factory, and the quality verification is completed after the factory is shipped, which further improves the prefabrication and reliability of the pipeline. When installing on site, the overall prefabricated module and the dry pipe can be connected by screw thread connection (such as FIG. 7) or flange connection (such as FIG. 8), so that the overall prefabricated module only needs to be connected with the dry pipe when installed on site, which greatly reduces the number of interfaces installed on site, thereby avoiding complex installation work on site and significantly simplifying the installation difficulty on site.

[0162] The single-sided pipeline subsystem prefabricated module and the double-sided pipeline subsystem prefabricated module have the same principle, which will not be described here.

[0163] The present disclosure preferably adopts a distributed CDU (cold distribution unit) scheme. The distributed CDU is arranged below each decoupled liquid cooling cabinet 11. The pipe material of the liquid cooling coolant and the air cooling chilled water can be unified, facilitating pipe prefabrication, and saving secondary side pipes and reducing material costs. For the machine room, the distributed CDU does not occupy cabinet space, more cabinets can be arranged in the machine room, and the overall installed efficiency is higher. For the pipe system, the distributed CDU scheme has no secondary side pipe in the machine room, the coolant can be circulated directly at the cabinet side, the failure influence range is limited in a single cabinet, and the reliability is higher. For the business upper limit, the distributed CDU can be started and used according to the business, there is no waste of cold, and there is no need to consider power balance between cabinets. The coolant flow and temperature in the cabinet can be automatically adjusted according to the operation characteristics of each cabinet to meet the liquid cooling server business demand.

[0164] Please refer to FIG. 9 and FIG. 10, in other embodiments, the present application can also adopt a centralized CDU 13 scheme. In one embodiment, one end of each column cabinet group is provided with a centralized cold distribution unit. One side of the centralized cold distribution unit is connected with a primary side liquid cooling pipe subsystem. The data center multi-connection heat dissipation pipe system further includes a secondary side liquid cooling pipe subsystem 400. One side of the centralized cold distribution unit away from the primary side liquid cooling pipe subsystem is connected with the secondary side liquid cooling pipe subsystem 400. The secondary side liquid cooling pipe subsystem 400 is arranged separately from the air cooling pipe subsystem 300. The primary side liquid cooling pipe system has the same structure as the above-mentioned liquid cooling pipe subsystem, that is, the primary side liquid cooling pipe system can be a single-side liquid cooling pipe subsystem 202 or a double-side liquid cooling pipe subsystem 201, which will not be repeated here.

[0165] It can be understood that the liquid cooling pipe system using the centralized CDU 13 heat exchange, the centralized CDU 13 is arranged in the column, the secondary side liquid cooling pipe subsystem 400 has a short delivery distance and low pipe cost, and maintenance is concentrated and convenient to operate and maintain. In the centralized CDU 13 scheme, the liquid cooling cabinet 11 is a non-decoupled liquid cooling cabinet 11.

[0166] The centralized CDU 13 is arranged at the end of each column cabinet group. One end of the primary side liquid cooling pipe system is connected with the external cold source pipe, and the other end forms a ring pipe inside the machine room to realize the online maintenance function. The secondary side liquid cooling pipe subsystem 400 uses stainless steel pipes to deliver and distribute the liquid cooling coolant due to the water cleanliness requirement. Although the pipe materials corresponding to the primary side liquid cooling pipe system and the secondary side liquid cooling pipe subsystem 400 are different, the liquid cooling pipe subsystem corresponding to the centralized CDU 13 and the distributed CDU has one end connected with the external cold source and the other end connected with the distributed CDU / centralized CDU 13. Only standard interfaces are reserved at both ends of the main pipe, the structure of the two liquid cooling pipe subsystems remains the same, and modular prefabrication can be performed, which will not be repeated here.

[0167] As shown in FIG. 10, one embodiment of the secondary liquid cooling pipeline subsystem 400 is described as follows:

[0168] The secondary liquid cooling pipeline subsystem 400 connects the external cold source and the centralized CDU 13, which includes two A and B routes of double supply and double return, i.e., two secondary supply water main pipes 41 and two secondary return water main pipes 42, and the secondary supply and return water main pipes are provided with components such as stop valves 1, electric regulating valves 2, pressure sensors 3, temperature sensors 4, Y-type filters 5, and the like at the interface with the cold source side and the centralized CDU 13. The double-route secondary supply water main pipe 41 is connected in parallel by multiple secondary supply water branch pipes 43, and the double-route secondary return water main pipe 42 is connected in parallel by multiple secondary return water branch pipes 44. One group of secondary supply and return water branch pipes connects two left and right centralized CDUs 13 arranged face to face, and the number of groups of secondary supply and return water branch pipes corresponds to half the number of centralized CDUs 13. Since each side of the centralized CDU 13 has been considered as a backup, each centralized CDU 13 only needs to be connected to one of the A and B routes of the secondary supply and return water pipeline through the supply and return water branch pipes, which can avoid single-point failure and meet the requirement of online maintenance.

[0169] As shown in FIGS. 1 and 9, it should be noted that the data center multi-connection liquid cooling pipeline system further includes electrical matching cabinet positions 14, fire-fighting environment matching cabinet positions 15, and the like, and the specific positions can be installed and inserted in each column of cabinet groups. The installation positions and the number can be set according to actual needs, which are not limited here.

[0170] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
