Simultaneously, the power consumption of communication equipment in communication rooms and data centers has also increased rapidly, leading to increasingly stringent heat dissipation requirements for communication rooms and data centers.

[0005] In the related art, a refrigeration device is generally provided in a modular DC cabin, and the refrigeration device blows cold air to multiple communication devices in the cabin at the same time, thereby achieving simultaneous cooling of the multiple communication devices.

[0044] Referring to FIG. 1 , an embodiment of the present application provides a modular DC pod, which includes multiple cabinets 100 and an air guide member. The cabinets 100 are arranged sequentially along a first direction OX. At least one cabinet 100 is used to house communication equipment. Along the first direction OX, the cabinets 100 are provided with interconnected hot air ducts 110 and interconnected cold air ducts 120. At least one cabinet 100 is provided with a hot air inlet and a cold air outlet. The hot air inlet communicates with the hot air duct 110, and the cold air outlet communicates with the cold air duct 120. The air guide member has one end configured to communicate with the air inlet of the communication equipment and the other end configured to communicate with the cold air duct 120. Alternatively, the air guide member may have one end configured to communicate with the air outlet of the communication equipment and the other end configured to communicate with the hot air duct 110.

[0045] It should be noted that the hot air inlet on the cabinet 100 is used to communicate with the return air outlet of the refrigeration device 200, and the cold air outlet is used to communicate with the air outlet of the refrigeration device 200. The refrigeration device 200 can be installed in the cabinet of the modular DC cabin or in the modular DC machine room.

[0046] In this embodiment, when the air inlet position of the communication equipment within the cabinet changes, since multiple cabinets are provided with interconnected cold air ducts 120, air guide components need only be provided within the cabinet to quickly direct the cold air closest to the communication equipment from the cold air ducts 120 into the communication equipment. This connection method not only meets the heat dissipation requirements of different communication equipment, but also significantly increases the cooling effect of the refrigeration device 200 due to the short cold air path and low wind resistance along the way, effectively dissipating heat from the communication equipment.

[0047] When the air outlet position of the communication equipment changes, since multiple cabinets are provided with interconnected hot air ducts 110, the communication equipment can be connected to the hot air ducts 110 through air guide components. This allows the hot air from the communication equipment to quickly pass through the hot air ducts 110 and return to the refrigeration unit 200, thereby reducing heat loss and increasing the return air temperature of the refrigeration unit 200. This in turn increases the energy efficiency of the refrigeration unit 200 and improves the heat dissipation efficiency of the communication equipment. This also prevents heat from being directly lost to the modular DC room, which would increase the room's heat load and energy consumption.

[0048] When the positions of the air inlet and air outlet of the communication equipment are changed at the same time, the cold air channel is connected to the air inlet of the communication equipment through the air guide component, and the air outlet of the communication equipment is connected to the hot air channel, thereby improving the cooling efficiency of the refrigeration device and the heat dissipation efficiency of the communication equipment.

[0049] In some embodiments, a plurality of cabinets are provided with a hot air passage 110 on one side along the second direction OY, and a cold air passage 120 on the other side along the second direction OY, where the second direction is perpendicular to the first direction.

[0050] Based on the placement orientation of the modular DC pod, the side of the cabinet 100 with the door is defined as the front side, and the side opposite the front side is defined as the rear side. The cabinet 100 also has a bottom and a top. A first direction OX represents the direction in which the multiple cabinets extend, and a second direction OY represents the front-to-back direction of the cabinet. The cold air duct 120 and the hot air duct 110 can be located at the front and rear sides of the cabinet 100, respectively. For ease of description, the following example illustrates the cold air duct 120 located at the front side of the cabinet 100 and the hot air duct 110 located at the rear side.

[0051] In some embodiments, referring to FIG2 , the air guide member includes a first cold air guide member 300, which includes a first cold air guide member 310 and a first cold air guide connector 320. The first cold air guide member 310 is disposed close to the side wall of the cabinet 100, and the first cold air guide member 310 is used to form a first cold air guide channel, which is connected to the cold air channel 120. The first cold air guide connector 320 is disposed on the first cold air guide member 310 and is located within the hot air channel 110. The inlet end of the first cold air guide connector 320 is connected to the first cold air guide channel, and the outlet end of the first cold air guide connector 320 is used to connect to the air inlet of the communication equipment. The side wall of the cabinet refers to a wall surface where two adjacent cabinets 100 are close to each other or shared by two adjacent cabinets 100.

[0052] In actual use, the aforementioned communications equipment may be an OTN-type communications equipment. Air inlets are located on both the front and rear sides of the communications equipment, requiring simultaneous cooling from both sides. Multiple air inlets are provided on either the front or rear side of the communications equipment. In this case, the front side of the communications equipment can be directly connected to the cold air duct 120, allowing cool air to be supplied directly through the cold air duct 120. Specifically, multiple first cold air duct connectors 320 can be installed on the cold air duct 120. The number and location of the first cold air duct connectors 320 correspond to the number and location of the air inlets on the front side of the communications equipment. Cool air is supplied to the communications equipment through the first cold air duct connectors 320. The rear side of the communications equipment is connected to the first cold air duct connectors 320, allowing cool air to be delivered sequentially from the cold air duct 120, the first cold air guide 310, and the first cold air duct connectors 320 to the rear side of the communications equipment. This achieves precise cooling of the OTN-type communications equipment from both sides. Furthermore, since the first cold air guiding member 310 is disposed close to the side wall of the cabinet 100 , when the cold air passes through the first cold air guiding channel, it is convenient to directly conduct heat with the side wall of the cabinet 100 , thereby increasing the heat dissipation efficiency.

[0053] The first cold air guide member 310 may be an air guide plate, which is spaced apart from a side wall of the cabinet 100 along a first direction to form a first cold air channel. The air guide plate and the top, bottom, and rear side of the side wall of the cabinet 100 may be sealed. The front side of the air guide plate extends into the cold air channel 120, and the rear side of the air guide plate and the side wall of the cabinet 100 are sealed to form a rear wall. A through hole is provided in the rear wall that communicates with the first cold air guide connector 320. In other words, cold air from the refrigeration device 200 can sequentially pass through the cold air channel 120, the first cold air guide channel, the through hole, and the first cold air guide connector 320 to enter the air inlet on the rear side of the communication equipment.

[0054] In actual use, to facilitate the installation of the first cold air ducting connector 320, the first cold air ducting connector 320 can be directly installed on the cabinet door or the rear wall of the cabinet 100. When the first cold air ducting connector 320 is installed on the cabinet door, a blocking member is further provided between two adjacent first cold air ducting connectors 320. When the cabinet door is closed, the blocking member is used to seal the air guide plate from the rear side of the side wall of the cabinet 100 while maintaining the connection between the first cold air ducting connector 320 and the first cold air ducting channel.

[0055] Furthermore, the cross-section of the first cold air duct connector 320 along the second direction OY gradually decreases from the side closest to the communication equipment air inlet to the side further away from the communication equipment air inlet. This ensures that the outgoing air pressure is greater than the incoming air pressure, facilitating the rapid entry of cold air into the communication equipment air inlet. The second direction OY refers to the front-to-back direction of the cabinet 100. The outlet of the first cold air duct connector 320 needs to be adapted to the size of the communication equipment air inlet.

[0056] Specifically, the first cold air guide joint 320 includes a third side wall 323, a second side wall 322 and a fourth side wall 324. The third side wall 323 and the fourth side wall 324 are spaced apart along the first direction OX. The ends of the third side wall 323 and the fourth side wall 324 away from the communication equipment are connected through the second side wall 322. Along the direction away from the communication equipment, the third side wall 323 and the fourth side wall 324 gradually approach each other, and the end of the third side wall 323 close to the communication equipment is connected to the first cold air guide member 310.

[0057] In actual use, the first cold air guide joint 320 also includes a fifth side wall 325 and a sixth side wall 326 located on both sides of the third side wall 323 and the fourth side wall 324 along the third direction. There is no connection between the ends of the third side wall 323 and the fourth side wall 324 near the communication device to form the inlet end of the first cold air guide joint 320. Along the direction away from the communication device, the third side wall 323 and the fourth side wall 324 gradually approach each other, and the end of the third side wall 323 near the end of the communication device is connected to the first cold air guide member 310, that is, the third side wall 323 is an inclined surface, so that after the cold air from the first cold air guide member 310 enters the inlet end of the first cold air guide joint 320, it can be smoothly transitioned to the air inlet of the communication device under the guidance of the third side wall 323 (inclined surface). That is, the connection position of the first cold air guide member 310 and the first cold air guide joint 320, as well as the structural setting of the first cold air guide joint 320, can reduce the resistance along the cold air during the circulation process, thereby improving the energy efficiency of the refrigeration device and increasing the heat dissipation efficiency.

[0058] In some other embodiments, referring to FIG2 , the air guide member includes a first heat-conducting member 400, which includes a first heat-conducting member 410 and a first heat-conducting connector 420. The first heat-conducting member 410 is disposed proximate to the side wall of the cabinet 100 and is configured to form a first heat-conducting channel, which is in communication with the hot air channel 110. The first heat-conducting connector 420 is disposed within the cold air channel 120, with the inlet end of the first heat-conducting connector 420 configured to communicate with the air outlet of the communication device, and the outlet end of the first heat-conducting connector 420 communicating with the first heat-conducting channel.

[0059] In actual use, when the air outlets of OTN communication equipment are respectively arranged on the front and rear sides of the communication equipment, both the front and rear sides need to be connected to the hot air duct 110 at the same time. In this case, a first heat-conducting member 400 is required to assist in connecting the air outlet on the front side of the communication equipment to the hot air duct 110. The specific implementation and effect of the first heat-conducting member 400 are similar to those of the first cold-conducting member 300 described above.

[0060] In other embodiments, when the air inlet of the OTN communication equipment is close to the rear side of the cabinet 100 and the air outlet is close to the front side of the cabinet 100, the air guide member includes a first cold air guide member 300 and a first hot air guide member 400. The first cold air guide member 300 guides cold air from the cold air duct 120 on the front side of the cabinet 100 to the rear side of the cabinet 100 so as to enter the communication equipment through the air inlet of the communication equipment. The first hot air guide member 400 guides hot air from the front side of the cabinet 100 to the hot air duct 110 on the rear side of the cabinet 100 so as to guide the hot air exhausted from the communication equipment into the hot air duct 110.

[0061] In some embodiments, referring to FIG3 , a cold connecting passage 130 is defined along one side of the cabinet 100 along a third direction OZ. One end of the cold connecting passage 130 is connected to the cold air passage 120. The air guide member includes a second cold air guide member 500, which includes a second cold air guide member 510 and a second cold air guide connector 520. The second cold air guide member 510 is positioned within the hot air passage 110. The second cold air guide member 510 includes a second cold air guide channel, which is connected to the other end of the cold connecting passage 130. The second cold air guide connector 520 is disposed on the second cold air guide member 510, and the inlet end of the second cold air guide connector 520 is connected to the second cold air guide channel, while the outlet end of the second cold air guide connector 520 is configured to connect to the air inlet of the communication equipment. The third direction OZ refers to the vertical direction of the cabinet 100.

[0062] Similarly, in this embodiment, the air inlets of OTN communication equipment are located on both the front and rear sides of the equipment, requiring simultaneous cold air delivery from both sides. Specifically, multiple second cold air guide connectors 520 can be installed within the cold air duct 120 to deliver cold air to the communication equipment through the second cold air guide connectors 520. In this case, the front side of the communication equipment can be directly connected to the cold air duct 120, allowing cold air to be delivered directly through the cold air duct 120. The rear side of the communication equipment can be connected to the second cold air guide connectors 520, allowing cold air to be delivered to the rear side of the communication equipment in sequence through the cold air duct 120, the cold connecting duct 130, the first cold air guide 310, and the first cold air guide connector 320. This allows precise cold air delivery to both sides of the OTN communication equipment.

[0063] In actual use, since hot air flows upward, the cold connection channel is opened at the bottom of the cabinet 100 and the hot connection channel is opened at the top of the cabinet 100 .

[0064] In some other embodiments, referring to FIG3 , a thermal communication channel 140 is provided on the other side of the cabinet 100 along the third direction OZ. One end of the thermal communication channel 140 is connected to the hot air channel 110. The third direction is perpendicular to the first direction. The air guide component includes a second thermal air guide component 600. The second thermal air guide component 600 includes a second thermal air guide member 610 and a second thermal air guide joint 620. The second thermal air guide member 610 is located within the cold air channel 120. The second thermal air guide member 610 is provided with a second thermal air guide channel, which is connected to the other end of the thermal communication channel 140. The second thermal air guide joint 620 is provided on the second thermal air guide member 610. The inlet end of the second thermal air guide joint 620 is used to connect to the air outlet of the communication equipment, and the outlet end of the second thermal air guide joint 620 is connected to the second thermal air guide channel.

[0065] In other embodiments, when the air inlet of the OTN communication equipment is close to the rear side of the cabinet 100 and the air outlet is close to the front side of the cabinet 100 , the air guide member may also include a second cold air guide member 500 and a second hot air guide member 600 .

[0066] In addition, the air guiding member may include a first cold air guiding member 300 and a second hot air guiding member 600 , or the air guiding member may include a second cold air guiding member 500 and a first hot air guiding member 400 .

[0067] Referring to Figure 6, in some embodiments, multiple cabinets 100 are respectively provided with cold air channels 120 on both sides along the second direction OY, and multiple cabinets are also respectively provided with hot air channels 110 on both sides along the second direction OY. A partition 150 is provided between the hot air channel 110 and the cold air channel 120, and the hot air channel 110 is located on one side of the cold air channel 120 along the third direction OZ. The first direction OX, the second direction OY and the third direction OZ are perpendicular to each other.

[0068] In this embodiment, the refrigeration device also has two cold air outlets and two hot air inlets. The hot air inlets are located above the cold air outlets. The two cold air outlets are connected to the two cold air channels 120 in a one-to-one correspondence, and the two hot air inlets are connected to the two hot air channels 110 in a one-to-one correspondence. The hot air channels 110 are located above the cold air channels 120.

[0069] Referring to FIG. 7 , in some embodiments, the air guide member includes a third cold air guide member 700. When the air inlet of the OTN communication equipment is located above the cabinet, the cold air in the cold air duct 120 located below needs to be directed to the air inlet of the communication equipment through the third cold air guide member 700. Specifically, the third cold air guide member 700 includes a third cold air guide member 710 and a third cold air guide connector 720. The third cold air guide member 710 is disposed within the hot air duct 110. One end of the third cold air guide member 710 along the third direction OZ is connected to the cold air duct 120. The third cold air guide connector 720 is disposed on the third cold air guide member 710. The inlet end of the third cold air guide connector 720 is connected to the third cold air guide member 710, and the outlet end of the third cold air guide connector 720 is used to connect to the air inlet of the communication equipment.

[0070] In some other embodiments, the air guide member includes a third heat guide member 800. When the air outlet of the OTN communication equipment is located below the cabinet, that is, at this time, it is necessary to guide the hot air from the air outlet of the communication equipment into the hot air channel 110 located above the cabinet through the third heat guide member 800. Specifically, the third heat guide member 800 includes a third heat guide member 810 and a third heat guide joint 820. The third heat guide member 810 is disposed in the cold air channel 120. One end of the third heat guide member 810 along the third direction OZ is connected to the hot air channel 110. The third heat guide joint 820 is disposed on the third heat guide member 810. The inlet end of the third heat guide joint 820 is used to communicate with the air outlet of the communication equipment, and the outlet end of the third heat guide joint 820 is connected to the third heat guide member 810.

[0071] In other embodiments, the air guiding member includes a third cold air guiding member 700 and a third hot air guiding member 800. When the air inlet of the OTN communication equipment is located above the cabinet and the air outlet is located below the cabinet, that is, when the air inlet is above the air outlet, the third cold air guiding member 700 is required to guide the cold air in the cold air duct 120 located below to the air inlet of the communication equipment, and the third hot air guiding member 800 is required to guide the hot air from the air outlet of the communication equipment to the hot air duct 110 located above the cabinet.

[0072] In some embodiments, the number of the first cold air joint 320, the second cold air joint 520, the first hot air joint 420, and the second hot air joint 540 can be one or more. Taking the first cold air joint 320 as an example, the actual number of the first cold air joint 320 is greater than or equal to the number of air outlets of the communication equipment. The first cold air joint 320 is disposed on a cabinet door or air guide plate via a movable component, and the air outlet of the first cold air joint 320 is provided with a stopper component (not shown). When the actual number of the first cold air joint 320 is greater than the number of air outlets of the communication equipment, the unnecessary air outlets can be blocked by the stopper component, and the first cold air joint 320 can be moved by a movable component (not shown) to correspond to the air inlet position of the communication equipment. The movable component can be a linear movable module, and the stopper component can be a rolling leaf curtain.

[0073] In some embodiments, the modular DC cabin further includes a refrigeration device 200 , which is disposed in at least one cabinet 100 , and a hot air inlet and a cold air outlet are respectively provided on the cabinet where the refrigeration device 200 is located.

[0074] Since the refrigeration device 200 is arranged in the cabinet, and the cold air channel 120 and the hot air channel 110 are both sealed in the cabinet 100, the exchange of cold and heat with the outside world can be reduced to a minimum, eliminating the phenomenon of turbulent cold and hot air flows in the cabinet, effectively improving the energy efficiency ratio of the refrigeration device 200 and the cold utilization rate of the cabinet, and at the same time greatly reducing the insulation and sealing requirements of the computer room, it can be applied to a variety of scenarios.

[0075] In some embodiments, referring to FIG1 , a refrigeration device 200 includes a refrigeration element and a fan 240 . The refrigeration element is used to convert hot air from the hot air channel 110 into cold air. The fan 240 is disposed in the cold air channel 120 and is used to blow the cold air from the refrigeration element into the cold air channel 120 .

[0076] In this embodiment, the fan 240 can be a centrifugal EC fan 240. The fan 240 is arranged in the cold air channel 120. After the fan 240 is running, the wind is directly thrown out and directly connected with the cold air channel 120 of the cabinet 100, which increases the smoothness of the wind flow and the air flow direction will not conflict with the structure of the cabinet 100.

[0077] Furthermore, refrigeration device 200 can be an indoor unit of an air conditioner, wherein the refrigeration element is a V-shaped evaporator. The V-shaped evaporator maximizes the use of the air conditioner cabinet height, increases the heat dissipation area, and improves the cooling capacity. In actual use, an outdoor unit can be installed outside the machine room. The outdoor unit uses an open cooling source and is compatible with a central air conditioning chilled water system, a fluorine pump cooling source, a plate heat exchanger, or a compressor.

[0078] The modular DC cabin includes a row cabinet, a refrigeration cabinet, a standard cabinet, and a TN cabinet. The standard cabinets are equipped with blind panels at the front and back, allowing for installation of communication equipment as needed. The blind panels are used to separate the cold air duct 120 from the hot air duct 110.

[0079] Furthermore, there are multiple refrigeration devices 200 , and the multiple refrigeration devices 200 are respectively arranged in multiple cabinets 100 spaced apart from each other.

[0080] Taking a modular DC cabin as an example, it includes three refrigeration unit cabinets, 10 communication equipment cabinets, and two front-end cabinets. The three refrigeration unit cabinets divide the 10 communication equipment cabinets into two equal parts, with the two front-end cabinets located on either side of the entire modular DC cabin along a first direction. Under normal circumstances, two refrigeration units can be used for cooling, with the other serving as a backup, to improve the reliability of the modular DC cabin. Alternatively, the modular DC cabin can include four refrigeration unit cabinets, 15 communication equipment cabinets, and two front-end cabinets, with the four refrigeration unit cabinets dividing the 15 communication equipment cabinets into three equal parts.

[0081] The modular DC pod is fully decoupled from the internal communications equipment. Each cabinet 100 is 600mm wide (e.g., 605mm wide), 2200mm high (e.g., 2300mm high), and 1400-1600mm deep (depending on the requirements of the communications equipment). The rack space can accommodate communications equipment racks or server racks as needed. When the first cold air guide 300 or the first hot air guide 400 is installed, the cabinet 100 width is 650-700mm.

[0082] In some embodiments, the modular DC pod further includes a controller and a temperature sensor. The controller is electrically connected to the temperature sensor and the fan of the refrigeration unit 200, respectively. Temperature sensors are provided in the cold air duct 120 and the hot air duct 110, respectively. The controller is configured to obtain the difference between the temperature sensor in the cold air duct 120 and the temperature sensor in the hot air duct 110, and adjust the air outlet speed of the refrigeration unit 200 based on the temperature difference, thereby adjusting the speed of the fan 240. For example, when the temperature difference is large, the speed of the fan 240 is increased, and when the temperature difference is small, the speed of the fan 240 can be reduced.

[0083] In some embodiments, the modular DC pod includes a door mechanism that automatically pops open upon power failure. This mechanism includes an electromagnetic lock and a spring hinge. When the refrigeration unit 200 is operating normally, the electromagnetic lock holds the door locked, compressing the spring hinge. If the refrigeration unit 200 experiences an abnormal operation or power failure, the electromagnetic lock loses its magnetic force, releasing the spring hinge and allowing the door to open, allowing temporary cooling to be provided by the computer room environment.

[0084] In some embodiments, the modular DC cabin includes a control system, which can perform real-time energy consumption monitoring, real-time PUE calculation and annual PUE calculation on the cabin. Since multiple refrigeration units 200 are connected through interconnected cold air channels 120 and hot air channels 110, a unified detection port can be set in the modular DC cabin, and all data can be uploaded to the control system at one time.

[0085] Referring to Figures 4 and 5, a modular DC computer room is provided in an embodiment of the present application. The modular DC computer room includes a transfer channel 30 and the above-mentioned modular DC cabin. The transfer channel 30 is located on at least one side (bottom or top) of multiple modular DC cabins along the third direction. The cold air channels 120 of multiple modular DC cabins are interconnected through the transfer channel 30, and the hot air channels 110 of multiple modular DC cabins are interconnected through the transfer channel 30.

[0086] In this embodiment, when the transfer channel 30 is located at the bottom of multiple modular DC cabins, the transfer channel 30 can be a buried pipe, such as shown in Figure 5. Through the transfer channel 30, all cold air channels 120 and all hot air channels 110 are connected in series. This allows all communication equipment within the modular DC room to share the cooling capacity of the refrigeration system. In most high-load operating conditions, only some of the air conditioners need to be turned on to meet cooling needs. If the refrigeration system in one modular DC cabin fails, another modular DC cabin can provide temporary emergency cooling. Specifically, the top portion of the modular DC room is provided with a high-voltage wiring trough and a low-voltage wiring trough.

[0087] In some embodiments, multiple cabinets are provided with a hot air duct 110 on one side along the second direction OY and a cold air duct 120 on the other side along the second direction OY. The modular DC room includes a first modular DC compartment 10 and a second modular DC compartment 20 arranged opposite each other. The cold air duct 120 of the first modular DC compartment 10 is located on a side proximal to the second modular DC compartment 20, while the cold air duct 120 of the second modular DC compartment 20 is located on a side proximal to the first modular DC compartment 10. In other words, the cold air ducts 120 of the first modular DC compartment 10 and the second modular DC compartment 20 are located on a side proximal to the first modular DC compartment 10. This means that the proximity of the cold air ducts 120 of the first modular DC compartment 10 and the second modular DC compartment 20 minimizes the length of the transfer duct 30, thereby reducing cold loss and improving the cooling efficiency of the refrigeration unit 200.

[0088] In some other embodiments, multiple cabinets 100 are provided with cold air ducts 120 on both sides along the second direction OY, and multiple cabinets are further provided with hot air ducts 110 on both sides along the second direction OY. A partition 150 is provided between the hot air duct 110 and the cold air duct 120, and the hot air duct 110 is located on one side of the cold air duct 120 along the third direction OZ. The modular DC computer room includes a first modular DC cabin 10 and a second modular DC cabin 20 arranged opposite each other. The cold air duct 120 of the first modular DC cabin 10 and the cold air duct 120 of the second modular DC cabin 20 are connected via a transfer channel 30 located at the bottom of the cabin, and the hot air duct 110 of the second modular DC cabin 20 is connected to the hot air duct 110 of the first modular DC cabin 10 via the transfer channel 30 located at the top of the cabin.

[0089] The communication equipment within the first and second modular DC bays 10 and 20 can share the cooling capacity of the refrigeration system. Under most high-load conditions, only some of the air conditioners need to be turned on to meet cooling needs. If the refrigeration system in one modular DC bay fails, the other modular DC bay can provide temporary emergency cooling.
