[0002] With the continuous development of large models and other technologies, the power of data center cabinets has also increased significantly, such as from 5-10 kilowatts (kw) before to 20-50 kw now, and especially for artificial intelligence cluster cabinets, the power may even exceed 100 kw. Correspondingly, the traditional air cooling technology has been unable to meet the cooling (i.e., heat dissipation or refrigeration) needs of the cabinets due to physical limits and energy efficiency bottlenecks and other reasons.

[0017] Exemplary embodiments of the present disclosure are described herein below with reference to the accompanying drawings, in which various details of embodiments of the present disclosure are set forth to facilitate an understanding, and should be considered as merely exemplary. Thus, it will be appreciated that various modifications and changes can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Also, for the sake of brevity and clarity, descriptions of well-known functions and constructions are omitted herein.
[0018] In addition, it should be understood that the term "and / or" as used herein merely describes an associated relationship between associated objects, and can represent three relationships, for example, A and / or B can represent three cases of A alone, A and B together, and B alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.
[0019] With the air cooling technology failing to meet the cooling needs of the cabinet, the liquid cooling technology gradually becomes the mainstream cabinet cooling method due to its thousand-fold heat dissipation efficiency and ultra-high energy efficiency.
[0020] In the current liquid cooling implementation, the design institute usually selects equipment and designs system pipelines for specific liquid cooling projects, and generates related drawings. Then, each equipment manufacturer sends the equipment responsible for it to the project site, and then the construction unit installs the equipment and connects the pipelines according to the drawings. This method involves multiple links such as design, generation and construction, and each link is performed in series, so the entire cycle is long, and moreover, each equipment is sent to the site for installation, the equipment layout is scattered, and the land occupation is very large.
[0021] Correspondingly, the scheme of the present disclosure proposes a liquid cooling source system to overcome the above various problems. The liquid cooling source system according to the present disclosure is described in detail through multiple embodiments as follows.
[0022] Embodiment one
[0023] Figure 1A first schematic diagram of a first set of structures of the liquid-cooled cooling source system 100 according to the present disclosure is shown in FIG. 1. As shown in FIG. 1, the first set of structures includes M sets of prefabricated cold units (PCUs) 11 and N sets of prefabricated auxiliary units (PAUs) 12, where M and N are positive integers. The specific values of M and N can be determined according to actual needs, and for simplicity of the drawings, it is assumed in the following description that M and N are both equal to 1. Figure 1 Figure 1
[0024] The prefabricated cold units 11 are used to cool a cabinet to be cooled by a liquid cooling method, and the prefabricated auxiliary units 12 are connected to the prefabricated cold units 11 and used to optimize the quality of a cooling medium used in the liquid cooling method.
[0025] In the above embodiment, the liquid-cooled cooling source system 100 is composed of the prefabricated cold units 11 and the prefabricated auxiliary units 12. In actual applications, the values of M and N can be determined according to actual needs, and then the prefabricated cold units 11 and the prefabricated auxiliary units 12 can be produced by a prefabrication method in a factory. The prefabricated cold units 11 can be used to provide a cooling source for the liquid-cooled cooling source system 100, and the cabinet to be cooled can be cooled by a liquid cooling method. The prefabricated cold units 11 can be integrated and debugged by a prefabrication method in the factory, and external water pipes and power supply interfaces can be reserved to facilitate on-site assembly. The prefabricated auxiliary units 12 are auxiliary units in the liquid-cooled cooling source system 100, and can be used to optimize the quality of the cooling medium. The prefabricated auxiliary units 12 can also be integrated and debugged by a prefabrication method in the factory, and external water pipes and power supply interfaces can be reserved to facilitate on-site assembly. Accordingly, the device production process and the on-site construction process can be performed in parallel, thereby effectively shortening the overall cycle time and avoiding the problem of scattered device layout, saving floor space. In addition, the number and capacity of the prefabricated cold units 11 and the prefabricated auxiliary units 12 can be flexibly adjusted according to changes in business needs, thereby achieving rapid response and flexible deployment.
[0026] The cooling medium can be water, a glycol solution, or various liquid cooling media such as pure glycol. Typically, the cooling medium is water.
[0027] Embodiment Two
[0028] In response to the value of M being greater than 1, the M sets of prefabricated cold units 11 can be configured in a redundant manner, and divided into L sets of working prefabricated cold units and P sets of standby prefabricated cold units, where L and P are positive integers, and the sum of L and P is equal to M.
[0029] Multiple prefabricated refrigeration units 11 can be divided into two types: working prefabricated refrigeration units and standby prefabricated refrigeration units. When all working prefabricated refrigeration units are working normally, the standby prefabricated refrigeration units do not work. When any working prefabricated refrigeration unit malfunctions, any standby prefabricated refrigeration unit can be used to take over the work of the malfunctioning working prefabricated refrigeration unit.
[0030] Figure 2 This is a schematic diagram of the second component structure of the liquid-cooled cold source system 100 described in this disclosure. Figure 2 As shown, assume M is 4 and N is 1, meaning it includes 4 prefabricated refrigeration units 11 and 1 prefabricated auxiliary unit 12. For ease of description, the 4 prefabricated refrigeration units 11 are referred to as prefabricated refrigeration unit a, prefabricated refrigeration unit b, prefabricated refrigeration unit c, and prefabricated refrigeration unit d, respectively. Assume L is 3 and P is 1, and assume that prefabricated refrigeration units a, b, and c are the working prefabricated refrigeration units, and prefabricated refrigeration unit d is the backup. In a prefabricated cooling unit configuration, prefabricated cooling units a, b, and c operate under normal circumstances, while prefabricated cooling unit d does not operate. If any one of these units malfunctions, such as prefabricated cooling unit b, prefabricated cooling unit d can take over its operation. This 3+1 redundancy configuration improves the stability and reliability of the system.
[0031] The above describes the overall composition and structure of the liquid cooling cold source system 100. The composition and structure of the prefabricated refrigeration unit 11 and the prefabricated auxiliary unit 12 will be described below through embodiments three to eight.
[0032] Example 3
[0033] The prefabricated cooling unit 11 may include multiple components, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the first component structure of the prefabricated refrigeration unit 11 described in this disclosure, which includes: a first cold source device 111, a plate heat exchanger 112, a first water pump 113, and a second water pump 114.
[0034] The first cold source device 111, the first water pump 113 and the plate heat exchanger 112 form the first circulation loop, and the plate heat exchanger 112, the second water pump 114 and the cabinet to be cooled form the second circulation loop.
[0035] The first cold source device 111 is configured to cool the first high-temperature cooling medium from the plate heat exchanger 112 to obtain a first low-temperature cooling medium and provide the first low-temperature cooling medium to the plate heat exchanger 112.
[0036] The plate heat exchanger 112 is configured to exchange heat between the first low-temperature cooling medium and a second high-temperature cooling medium to obtain the first high-temperature cooling medium and a second low-temperature cooling medium, and the second low-temperature cooling medium is configured to exchange heat with the cabinet to be cooled to obtain the second high-temperature cooling medium.
[0037] In addition, in order to accelerate the circulation of the cooling medium, the first water pump 113 and the second water pump 114 are arranged, the first water pump 113 is configured to provide power for the circulation of the cooling medium in the first circulation loop, and the second water pump 114 is configured to provide power for the circulation of the cooling medium in the second circulation loop.
[0038] In some embodiments of the present disclosure, the first cold source device 111 can be an open cooling tower.
[0039] Taking water as an example, the open cooling tower can reduce the water temperature through the sensible heat exchange and latent heat exchange between water and air, thereby providing a cold source for the liquid cooling source system 100. For example, the open cooling tower can cool the first high-temperature water from the plate heat exchanger 112 to obtain first low-temperature water, and the first low-temperature water can be provided to the plate heat exchanger 112. In addition to the first low-temperature water, the plate heat exchanger 112 can also obtain second high-temperature water from the cabinet to be cooled. Then, the plate heat exchanger 112 can exchange heat between the first low-temperature water and the second high-temperature water, thereby obtaining the first high-temperature water and the second low-temperature water, respectively. The first high-temperature water is obtained by absorbing heat from the second high-temperature water by the first low-temperature water, and the second low-temperature water is obtained by releasing heat from the first low-temperature water by the second high-temperature water. The first high-temperature water returns to the open cooling tower for cooling, and the second low-temperature water is transported to the cabinet to be cooled to exchange heat with the cabinet to be cooled to obtain the second high-temperature water. This cycle is repeated to achieve the cooling of the cabinet to be cooled. After the first high-temperature water returns to the open cooling tower, the water temperature can be reduced through the sensible heat exchange and latent heat exchange between water and air. After the first high-temperature water contacts with the air, part of the water evaporates into water vapor. During this process, the air absorbs the latent heat of vaporization of the water, thereby effectively removing part of the heat in the first high-temperature water, i.e., reducing the water temperature through latent heat exchange. In addition, the temperature of the air is usually lower than the water temperature of the first high-temperature water. Therefore, after the first high-temperature water contacts with the air, the first high-temperature water exchanges heat with the air, thereby releasing part of the heat to the air, i.e., reducing the water temperature through sensible heat exchange. In this way, through the combination of sensible heat exchange and latent heat exchange, the water temperature of the first high-temperature water can be quickly reduced.
[0040] The first circulation loop can also be referred to as a primary side loop, i.e., a cold source side loop, and the second circulation loop can also be referred to as a secondary side loop, i.e., a cabinet side (or server side) loop.
[0041] The first water pump 113 and the second water pump 114 are both distribution equipment. The first water pump 113 is located in the first circulation loop and is a primary side water pump for providing power for circulation of the cooling medium in the first circulation loop. The specific location and power of the first water pump 113 can be determined according to actual needs. The second water pump 114 is located in the second circulation loop and is a secondary side water pump for providing power for circulation of the cooling medium in the second circulation loop. The specific location and power of the second water pump 114 can also be determined according to actual needs.
[0042] Embodiment Four
[0043] In addition to the first cold source equipment 111, the plate heat exchanger 112, the first water pump 113, and the second water pump 114 shown in Embodiment One, the prefabricated refrigeration unit 11 can further include some other components, such as related power distribution equipment. Figure 3
[0044] Correspondingly, Figure 4 A second constituent structure diagram of the prefabricated refrigeration unit 11 according to the present disclosure is shown in FIG. 2. As shown in FIG. 2, the prefabricated refrigeration unit 11 includes the first cold source equipment 111, the plate heat exchanger 112, the first water pump 113, the second water pump 114, the first power distribution cabinet 115, the second power distribution cabinet 116, and the third power distribution cabinet 117. Figure 4
[0045] Compared with the embodiment shown in Embodiment One, the prefabricated refrigeration unit 11 according to the present embodiment further includes the first power distribution cabinet 115, the second power distribution cabinet 116, and the third power distribution cabinet 117. Figure 3
[0046] The first power distribution cabinet 115 is a cold source equipment power distribution cabinet connected to the first cold source equipment 111 for power distribution control of the first cold source equipment 111. The second power distribution cabinet 116 is a primary side water pump power distribution cabinet connected to the first water pump 113 for power distribution control of the first water pump 113. The third power distribution cabinet 117 is a secondary side water pump power distribution cabinet connected to the second water pump 114 for power distribution control of the second water pump 114. The power distribution control can include various related controls such as power distribution, power protection, and state monitoring, thereby providing a basic guarantee for normal operation of the prefabricated refrigeration unit 11.
[0047] In practical applications, the plate heat exchanger 112, the first water pump 113, the second water pump 114, the first power distribution cabinet 115, the second power distribution cabinet 116, and the third power distribution cabinet 117 can be located in a container body to facilitate management and maintenance. Considering that the first cold source device 111 usually has a large size, the first cold source device 111 can be located outside the container body, for example, can be deployed in parallel with the container body or above the container body.
[0048] As can be seen, the prefabricated refrigeration unit 11 serves as a refrigeration and distribution unit in the liquid cooling cold source system 100, in which the refrigeration and distribution devices and the corresponding power distribution devices are integrated, and the integration and debugging can be performed in the factory through the prefabricated manner.
[0049] Embodiment five
[0050] Corresponding to the prefabricated refrigeration unit 11 shown in Figure 3 and Figure 4 , a first constituent structure schematic diagram of the prefabricated auxiliary unit 12 of the present disclosure is shown. As Figure 5 shown, it includes a first auxiliary unit 121 and a second auxiliary unit 122. Figure 5
[0051] Taking water as the cooling medium, the first auxiliary unit 121 can be used for impurity filtering treatment of the cooling medium in the first circulation loop, and the second auxiliary unit 122 can be used to realize at least one of the following functions: keeping the pressure in the second circulation loop constant, supplementing the cooling medium in the second circulation loop, and treating the cooling medium in the second circulation loop into softened water.
[0052] Embodiment six
[0053] Figure 5 As shown in the first auxiliary unit 121 and the second auxiliary unit 122, a plurality of devices can be further included, such as a plurality of different water treatment devices.
[0054] Correspondingly, Figure 6 a second constituent structure schematic diagram of the prefabricated auxiliary unit 12 of the present disclosure is shown. As Figure 6 shown, it includes a first auxiliary unit 121 and a second auxiliary unit 122, wherein the first auxiliary unit 121 can include a sand filter 1211 and an electromagnetic wave water treatment device 1212, and the second auxiliary unit 122 can include a constant pressure water supplementing device 1221 and a dosing device 1222.
[0055] The sand filter 1211, the electromagnetic wave water treatment device 1212, the constant pressure water supplementing device 1221, and the dosing device 1222 can be referred to as water treatment devices.
[0056] Taking water as an example of the cooling medium, the first auxiliary unit 121 can bypass the water (such as the first low-temperature water) in the first circulation loop, filter and then return to the first circulation loop, wherein the sand filter 1211 can be used to filter the sand and other impurities in the water, and the electromagnetic wave water treatment equipment 1212 can be used to filter the algae and microorganisms and other impurities in the water.
[0057] The second auxiliary unit 122 can be used to realize a variety of different functions, such as the constant-pressure water supplementing equipment 1221 can be used to keep the pressure in the second circulation loop constant and supplement water for the second circulation loop, and the dosing device 1222 can be used to treat the water in the second circulation loop as softened water, such as treating the municipal water in the second circulation loop as softened water.
[0058] With the help of the first auxiliary unit 121 and the second auxiliary unit 122, the quality of the cooling medium in the liquid cooling source system 100 can be improved, thereby improving the heat exchange efficiency and heat exchange effect, and improving the stability of the operation of the liquid cooling source system 100, etc.
[0059] Embodiment seven
[0060] When the cooling source equipment is the first cooling source equipment 111, the prefabricated refrigeration unit 11 can adopt the composition structure shown in Figure 3 or Figure 4 When the cooling source equipment changes, the composition structure of the prefabricated refrigeration unit 11 will also change accordingly.
[0061] Figure 7 A third composition structure diagram of the prefabricated refrigeration unit 11 of the present disclosure is shown. As Figure 7 shown, it includes a second cooling source equipment 118 and a third water pump 119.
[0062] The second cooling source equipment 118, the third water pump 119 and the cabinet to be cooled form a third circulation loop.
[0063] The second cooling source equipment 118 is used to cool the third high-temperature cooling medium, and obtain a third low-temperature cooling medium, which is used for heat exchange with the cabinet to be cooled to obtain a third high-temperature cooling medium.
[0064] In some embodiments of the present disclosure, the second cooling source equipment 118 can be a closed cooling tower.
[0065] Taking water as the cooling medium as an example, the water in the closed-circuit cooling tower flows inside the pipes. The water exchanges sensible heat with the air through the pipe walls. At the same time, spray cooling can be used to further reduce the water temperature, providing a cold source for the liquid cooling cold source system 100. The closed-circuit cooling tower can cool the third high-temperature water from the cabinet to be cooled, resulting in a third low-temperature water. The third low-temperature water is then transported to the cabinet to be cooled, where it exchanges heat with the cabinet to obtain a third high-temperature water. The third high-temperature water then returns to the closed-circuit cooling tower for cooling, and this cycle continues, thus achieving the cooling of the cabinet to be cooled.
[0066] In some embodiments of this disclosure, the second cold source device 118 may also be a dry cooler.
[0067] Taking water as the cooling medium as an example, the water in the dry cooler flows inside the pipes. The water exchanges sensible heat with the air through the pipe walls to lower its temperature, providing a cold source for the liquid cooling cold source system 100. The dry cooler can cool the third high-temperature water from the cabinet to be cooled, resulting in a third low-temperature water. This third low-temperature water is then transported to the cabinet to be cooled, where it exchanges heat with the cabinet to become a third high-temperature water. This third high-temperature water then returns to the dry cooler for further cooling. This cycle continues, thus achieving the cooling of the cabinet to be cooled.
[0068] Compared to open cooling towers, neither closed cooling towers nor dry coolers require plate heat exchangers 112. Consequently, there will only be one circulation loop in the system, namely the third circulation loop consisting of the second cold source device 118, the third water pump 119, and the cabinet to be cooled.
[0069] The third water pump 119 is located in the third circulation loop and is used to provide power for the circulation of the cooling medium in the third circulation loop. The specific location and power of the third water pump 119 can be determined according to actual needs.
[0070] Example 8
[0071] remove Figure 7 In addition to the second cold source device 118 and the third water pump 119 shown, the prefabricated refrigeration unit 11 may further include some other components, such as related power distribution equipment.
[0072] Accordingly, Figure 8 This is a schematic diagram of the fourth component structure of the prefabricated cooling unit 11 described in this disclosure. Figure 8 As shown, it includes: a second cold source device 118, a third water pump 119, a fourth power distribution cabinet 1110, and a fifth power distribution cabinet 1111.
[0073] Compared to Figure 7 The embodiment shown in this embodiment further includes a fourth power distribution cabinet 1110 and a fifth power distribution cabinet 1111 in the prefabricated refrigeration unit 11.
[0074] The fourth power distribution cabinet 1110 is a cold source equipment power distribution cabinet connected with the second cold source equipment 118, and is used for power distribution control of the second cold source equipment 118. The fifth power distribution cabinet 1111 is a water pump power distribution cabinet connected with the third water pump 119, and is used for power distribution control of the third water pump 119. The power distribution control can include various related controls such as power distribution, power protection, and state monitoring, thereby providing a basic guarantee for the normal operation of the prefabricated refrigeration unit 11.
[0075] In actual application, the third water pump 119, the fourth power distribution cabinet 1110 and the fifth power distribution cabinet 1111 can be located in a container body to facilitate management and maintenance. Considering that the volume of the second cold source equipment 118 is usually large, the second cold source equipment 118 can be located outside the container body, such as being deployed in parallel with the container body or being located above the container body.
[0076] Corresponding to the prefabricated refrigeration unit 11 shown in Figure 7 and Figure 8 The prefabricated auxiliary unit 12 can only include the second auxiliary unit 122.
[0077] Taking water as the cooling medium, the second auxiliary unit 122 can be used to realize at least one of the following functions: keeping the pressure in the third circulation loop constant, supplementing the cooling medium in the third circulation loop, and processing the cooling medium in the third circulation loop into softened water.
[0078] For example, the second auxiliary unit 122 can include a constant pressure water supplementing device 1221 and a dosing device 1222, wherein the constant pressure water supplementing device 1221 can be used to keep the pressure in the third circulation loop constant and supplement water in the third circulation loop, and the dosing device 1222 can be used to process the water in the third circulation loop into softened water.
[0079] With the help of the second auxiliary unit 122, the quality of the cooling medium in the liquid cooling cold source system 100 can be improved, thereby improving the heat exchange efficiency and effect and the stability of the operation of the liquid cooling cold source system 100, etc.
[0080] For the prefabricated refrigeration unit 11 using the open cooling tower described above, the water consumption is large in the ground application, and it can be applied to areas rich in water resources.
[0081] For the prefabricated refrigeration unit 11 using the closed cooling tower described above, the water consumption is moderate in the ground application, and since the pipeline is a closed system, the investment in water treatment equipment is less, and it can be applied to scenes with high water quality requirements.
[0082] For the prefabricated refrigeration unit 11 using the dry cooler, there is no water consumption in the ground application, and it can be applied to water-deficient areas such as desert areas, etc.
[0083] In summary, by using the liquid cooling source system 100 described in the present disclosure, different liquid cooling scenarios can be matched by flexibly adjusting the number of prefabricated refrigeration units 11 and prefabricated auxiliary units 12 and using different cooling source devices, so as to meet the use requirements of different scenarios.
[0084] The scheme described in the present disclosure can be applied to the field of artificial intelligence, and particularly relates to the fields of data centers, distributed deployment, large models, and liquid cooling technology.
