Detailed implementation manners

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0025] The following will be combined with Figures 1 to 3 , to describe the embodiments of the present invention.

[0026] Embodiment 1

[0027] The embodiment of the present invention provides a prefabricated module for a data center, including: an upper box 5 and a lower box 6. Inside the upper box 5, there is a cable tray 22 extending along the length direction of the upper box 5. On both sides in the width direction of the cable tray 22, an upper cold aisle 23 and an upper hot aisle 38 are respectively formed. The upper cold aisle 23 and the upper hot aisle 38 are communicated through the space above the cable tray 22. Inside the space above the cable tray 22, there is an air conditioning terminal 28, which can also be called an air conditioning cold end or an evaporator. Inside the upper cold aisle 23, the upper hot aisle 38 or the space above the cable tray 22, there is a pneumatic power source for driving the gas flow, and the pneumatic power source can be a fan or an air pump, etc.; inside the lower box 6, a plurality of cabinets are sequentially arranged along the length direction of the lower box 6. The cabinets at least include a computing power cabinet 12, a network cabinet 13, a distribution cabinet ( Figure 1The power distribution cabinet one 16 and the power distribution cabinet two 19), the UPS cabinet 17, the battery cabinet 18, the fire protection cabinet 20 and the liquid cooling cabinet 21 in it. The liquid cooling pipeline 36 is arranged in the space above the cabinet. The liquid cooling pipeline 36 is connected to the liquid cooling cabinet 21 and is communicated with the liquid cooling channels in the computing power cabinet 12 and the network cabinet 13. At least the sealing plates one 15 are fixedly arranged on both sides in the width direction of the space above the cabinet. The cabinet and the sealing plates one 15 divide the remaining space of the lower box 6 into a lower cold channel 40 and a lower hot channel 39. In the installed state, the upper box 5 is stacked on the upper part of the lower box 6. The lower cold channel 40 and the upper cold channel 23 are communicated, and the lower hot channel 39 and the upper hot channel 38 are communicated. It can be understood that before the prefabricated module of the data center is installed, the positional relationship between the upper box 5 and the lower box 6 is not limited.

[0028] The prefabricated module in the present invention is prefabricated in the factory and then transported to the corresponding site for installation. After installation, it can be put into use. Therefore, the present invention adopts the design concept of full prefabricated modularization to construct a new power supply and distribution and cooling system, realizing the rapid deployment of on-site assembled combination of the modular data center 1, and providing an innovative service platform for externally transporting computing power with green and low-carbon, rapid deployment, safety and high efficiency, and wide adaptability.

[0029] It should be noted that a heat dissipation structure communicating the lower cold channel 40 and the lower hot channel 39 is arranged on the cabinet, so that the lower cold channel 40, the lower hot channel 39, the upper hot channel 38 and the upper cold channel 23 are sequentially communicated to form a gas circulation loop, so that the gas in the cold channel can enter the cabinet to cool the components therein.

[0030] In some embodiments, the liquid cooling cabinet 21 can be a single-phase liquid cooling unit, or a phase change liquid cooling unit and other liquid cooling units.

[0031] In some embodiments, at least two sealing plates one 15 are arranged in the space above the cabinet, that is, the two sealing plates one 15 in the width direction. Of course, a sealing plate one can also be laid on the tops of the computing power cabinet 12 and the network cabinet 13, which can avoid the cooling liquid leaking into the computing power cabinet 12 and the network cabinet 13 after the liquid cooling pipeline 36 is damaged, and improves the safety.

[0032] In some embodiments, an anti-static layer 8 is laid on the bottom of the lower box 6.

[0033] In some embodiments, a network wire groove 25, a weak current wire groove 26 and a strong current wire groove 27 are arranged in the bridge 22. Sealing plates two 24 are arranged on both sides in the width direction of the bridge 22. The sealing plates two 24 are used to isolate the bridge 22 from the upper hot channel 38 and the upper cold channel 23.

[0034] In some embodiments, the length and width of the lower box 6 are the same as those of the upper box 5.

[0035] This embodiment makes the overall shape of the prefabricated module of the data center regular.

[0036] In some embodiments, a constant humidity unit 31 and a fresh air unit 32 are arranged in the space above the cable tray 22.

[0037] In some embodiments, fire shutter doors 7 are arranged on the four side surfaces of the upper box 5 and the lower box 6, and sliding doors 14 are arranged on at least one side surface of the upper box 5 and the lower box 6 in the length direction.

[0038] The fire shutter door 7 in this embodiment can be manually controlled or automatically controlled by a control system. When automatically controlled by the control system, corresponding control logic and sensors for detecting fire, such as smoke sensors or temperature sensors, etc., need to be set. Thus, when a fire occurs, the fire shutter door 7 can automatically descend to isolate the fire area. The sliding door 14 is provided to facilitate the staff to enter the box from one end of the upper box 5 and the lower box 6 to perform operations such as maintenance on the components.

[0039] This embodiment realizes the partition fire protection design. When a sudden fire occurs, the fire shutter door 7 quickly descends to isolate the fire area, and the gas fire extinguishing system quickly extinguishes the fire, which can effectively reduce the risk loss of the modular data center 1.

[0040] In some embodiments, a track extending along the vertical direction is arranged on the sliding door 14. When the fire shutter door 7 is converted from the open state (i.e., the state of being wound up at the top) to the closed state (i.e., the unfolded state), when the fire shutter door 7 slides down, the slider of the fire shutter door 7 enters the track from the top of the track, and the track is used to assist the fire shutter door 7 to slide down vertically to improve the stability of its sliding down process and the closed state.

[0041] It should be noted that under normal conditions, the sliding door 14 is always in the closed state, that is, under normal conditions, all the tracks are in their original positions and can provide sliding support for the fire shutter door 7. Only when the maintenance personnel enter the box, the sliding door 14 is opened. Therefore, under normal conditions, the sliding door 14 can provide sliding support for the fire shutter door 7. In addition, as Figure 3For the modular data center 1 shown, under normal conditions, the fire shutter door 7 inside it is always in the open state and does not require the support of the upper track of the sliding door 14. As for the fire shutter door 7 at the outermost long side, since the fire shutter door 7 at the outermost long side is usually in the closed state, its track is no longer fixed to the sliding door but to the frame of the sliding door. The track corresponding to the fire shutter door 7 at the short side is still arranged on the sliding door 14. However, since the fire shutter door 7 is usually located outside the sliding door 14, when entering the box body, it is necessary to first open the fire shutter door 7 and then open the sliding door 14. Therefore, in this embodiment, the purpose of arranging the track of the fire shutter door 7 on the sliding door 14 can be achieved.

[0042] This embodiment does not require additional columns to install the track, which greatly reduces the number of columns inside the data center, increases the activity space for staff or maintenance personnel, and facilitates the carrying out of work.

[0043] The sliding door in the above embodiment can also be replaced by a swing door.

[0044] In some embodiments, a partition 9 is arranged inside the lower box 6. The partition 9 is arranged along the length direction perpendicular to the lower box 6. The partition 9 divides the internal space of the lower box 6 into a main computer room 10 and a support area 11. A plurality of computing power cabinets 12 and network cabinets 13 are arranged in the main computer room 10; a power distribution cabinet, a UPS cabinet 17, a battery cabinet 18, a fire protection cabinet 20, and a liquid cooling cabinet 21 are arranged in the support area 11.

[0045] This embodiment uses a partition 9 to separate the main computer room 10 and the support area 11.

[0046] Preferably, the position of the partition 9 is adjustable, so as to facilitate adjusting the lengths of the main computer room 10 and the support area 11 as required. In this embodiment, the partition 9 can flexibly move to adjust the space ratio occupied by the main computer room 10 and the support area 11 according to the demand of computing power capacity.

[0047] In some embodiments, a grille 35 is fixedly arranged at the bottom of the upper cold channel 23.

[0048] The grille 35 in this embodiment can not only realize the air circulation but also serve as a passage for maintenance personnel. The air-conditioning maintenance personnel can perform the maintenance of the air-conditioning terminal 28 without entering the main computer room 10.

[0049] In some embodiments, a plurality of fans are sequentially arranged along the length direction at the bottom of the upper cold channel 23 to form a wind wall 29. The wind wall 29 is located below the grille 35. A plurality of air-conditioning terminals 28 are sequentially arranged along the length direction above the bridge 22. A wind valve 34 is arranged on one side of the air-conditioning terminal 28. One air-conditioning terminal 28 corresponds to one wind valve 34. In this embodiment, the air-conditioning terminal 28 and the wind wall 29 are independently arranged, and the air-conditioning terminal 28 and the wind wall 29 are out of the one-to-one correspondence relationship. When the refrigeration host or a certain evaporator (air-conditioning terminal 28) fails, the corresponding wind valve 34 is closed to avoid mixed air. The wind wall 29 operates normally, extracting the cold air in the upper cold channel 23, without affecting the cold quantity distribution. When a certain fan in the wind wall 29 fails, only the faulty fan needs to be processed, and it also does not affect the cold quantity distribution, significantly improving the system redundancy.

[0050] In some embodiments, the top of the upper box 5 is provided with a fixedly arranged top plate, and the bottom is provided with a detachably arranged bottom plate. The top of the lower box 6 is provided with a detachably arranged top plate, and the bottom is provided with a fixedly arranged bottom plate. The middle part of the upper box 5 and the lower box 6 is provided with fixedly arranged first columns 37, and the four side edges are provided with detachably arranged second columns 33.

[0051] In this embodiment, after the upper box 5 and the lower box 6 are prefabricated, their structure includes the bottom plate of the upper box 5, the top plate of the lower box 6, and the four second columns 33. That is, during the transportation process, the second columns 33, the bottom plate, and the top plate play a protective role for the components inside the box, such as structures like cabinets and air-conditioning terminals 28. It can be understood that in the transportation state, the four fireproof rolling doors 7 are all in the closed state, that is, the four fireproof rolling doors 7 serve as the four side walls of the upper box 5 and the lower box 6, and no additional side plates need to be set.

[0052] When transported to the site and during assembly, as Figure 3 shown, the four second columns 33, the bottom plate of the upper box 5, and the top plate of the lower box 6 can be disassembled and used as building materials for the middle corridor 30 to form the middle corridor 30.

[0053] As Figure 2 shown, the first columns 37 in the upper box 5 are fixedly connected to the top plate of the upper box 5, and the first columns 37 in the lower box 6 are fixedly connected to the bottom plate of the lower box 6. When the components in the upper box 5 and the lower box 6 need to be fixed in position, they can be fixedly connected to the top plate, the bottom plate, or the first columns 37. For example, first columns are arranged on both sides in the width direction of the bridge, and the bridge is fixedly connected to the first columns 37. The constant humidity unit 31, the fresh air unit 32, and the air-conditioning terminal 28 are all directly or indirectly connected to the first columns 37; first columns 37 are also arranged on both sides of the cabinet, and the cabinet can be directly or indirectly fixedly connected to the bottom plate, or directly or indirectly fixedly connected to the first columns 37.

[0054] Embodiment 2

[0055] An embodiment of the present invention provides a data center prefabricated unit 2, which includes two data center prefabricated modules as described in the above embodiments. In the installed state, the two data center prefabricated modules are symmetrically arranged along a vertical plane parallel to the length direction of the upper box 5.

[0056] In this embodiment, after the assembly is completed, the fireproof rolling doors 7 on the side where the two upper boxes 5 are close to each other and the fireproof rolling doors 7 on the side where the two lower boxes 6 are close to each other can be opened, which enables the two data center prefabricated modules to share the cold channel, increases the cold channel space, and further makes the cold quantity distribution in each module uniform, improving the refrigeration effect.

[0057] Embodiment III

[0058] An embodiment of the present invention provides a modular data center 1, which includes a plurality of data center prefabricated units 2, a medium-voltage distribution box 3, and a cooling outdoor unit 4 as described in the above embodiments.

[0059] After the modular data center 1 provided by the invention is assembled, only the cable, refrigeration pipeline, and liquid cooling pipeline 36 need to be connected to provide computing power. The cold and hot channels of the modular data center 1 are separated, and the air-conditioning terminal 28 is directly close to the server, further increasing the evaporation temperature. The air wall 29 accurately supplies air directly to the server to achieve cabinet-level cooling.

[0060] The medium-voltage distribution box 3 is installed near the data center prefabricated unit 2, and a medium-voltage power distribution cabinet and a transformer are arranged inside, which is directly connected to the 10KV medium-voltage power supply.

[0061] The cooling outdoor unit 4 can be one or a combination of several of a cooling tower, a chiller, a direct expansion air conditioner unit, a liquid cooling unit, and a phase change liquid cooling unit.

[0063] In some embodiments, a plurality of groups of data center prefabricated units 2 are provided, and the plurality of groups of data center prefabricated units 2 are arranged in sequence along the length direction of a single data center prefabricated unit 2, and there is a corridor 30 between adjacent two groups of data center prefabricated units 2.

[0064] When assembling the modular data center 1 using the prefabricated modules of the data center, the columns, the bottom plates and the top plates of the upper box 5 and the lower box 6 are removed, and then symmetrically assembled into a data center prefabricated unit 2. Using the columns, the bottom plates and the top plates, the corridor 30 of the modular data center 1 is assembled. After assembly, all the fireproof rolling doors 7 inside the modular data center 1 are opened (i.e., wound to the top), so that the cold channels and the hot channels can be effectively shared among the modules.

[0065] In addition, after all the internal fireproof rolling doors 7 are opened, any two adjacent lower boxes 6 and any two adjacent upper boxes 5 are connected into a space, which facilitates the maintenance and repair work of the staff.
