When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0048] It is worth noting that in addition to the DC cabin in this embodiment, there are many different forms of DC cabins, but the methods of achieving flexible cooling and power supply are the same, all of which are within the scope of protection of this application and will not be described in detail here.

[0049] Embodiment 1:

[0050] The embodiment of the present application proposes a DC compartment 100 with flexible power supply and cooling. The DC compartment with flexible power supply and cooling is described below with reference to the accompanying drawings.

[0051] Figure 1 A schematic diagram of the structure of a DC cabin with flexible power supply and cooling provided in an embodiment of the present application;

[0052] refer to Figure 1-Figure 14 , the DC cabin 100 with flexible power supply and cooling may include a small busbar system 10 and a refrigeration device 20;

[0053] The small busbar system 10 is used to supply power to the refrigeration equipment 20 and other equipment to be powered;

[0054] A decoupling structure 30 is disposed at the bottom of the refrigeration device 20 , and the decoupling structure 30 is used to enable the refrigeration device to be moved out of the DC compartment 100 , so as to achieve replacement of the refrigeration device 20 .

[0055] Since the transformation of the power supply of the traditional power supply cabinet is difficult and the investment cost is high, the embodiment of the present application adopts a small busbar system 10 to replace the power supply cabinet. The use of the small busbar system 10 can realize the pooling of the terminal distribution resources in the DC cabin 100 and the flexible allocation of power. In addition, the small busbar system 10 supplies power to the refrigeration equipment 20 and other equipment to be powered. Among them, through the reasonable over-allocation of the small busbar distribution capacity, it supports the future power increase of the cabinet or the addition of a new cabinet, and realizes the flexible expansion demand of the power supply in the DC cabin.

[0056] Moreover, a decoupling structure 30 is provided at the bottom of the refrigeration equipment 20, wherein the refrigeration equipment 20 can be an inter-row air conditioner. It should be noted that the DC cabin 100 includes multiple cabinets, and the refrigeration equipment 20 is placed in the cabinet of the DC cabin. The decoupling structure 30 is equivalent to realizing the structural decoupling design of the refrigeration equipment and the cabinet, so that the refrigeration equipment 20 can be flexibly withdrawn from the DC cabin 100 and replaced with other types of refrigeration equipment to meet the demand for refrigeration expansion. Realize online transformation of the refrigeration system and reduce the impact of the transformation on the original refrigeration system. Solve the problem that the DC cabin cannot be dismantled and modified online, and the transformation affects the business.

[0057] Figure 2 Schematic diagram of the traditional power supply architecture of the DC compartment.

[0058] Depend on Figure 2It can be seen that the cabinet is connected to multiple racks through cables, and multiple racks are arranged together according to a certain layout. Each rack is connected to the cabinet through cables and receives power supply from the cabinet. The rack usually contains multiple installation slots for placing different types of IT equipment. Among them, the rack can be the cabinet described in the embodiment of the present application.

[0059] Cables are drawn from the power supply cabinet to the racks for one-to-one power supply. There are many cables between the power supply cabinet and the cabinets. The wiring routes are fixed by the wiring rack. The cables take up a lot of space and are piled up in large quantities at the cabinet inlet. When the rack power in the DC compartment is increased or a new rack is needed, the capacity of the original power supply system may need to be expanded simultaneously. The original power supply cabinets and cables need to be redesigned and replaced. The transformation workload is huge and the quality is difficult to guarantee.

[0060] Depend on Figure 1 It can be seen that the flexible DC cabin mainly includes auxiliary facilities such as power supply equipment, refrigeration equipment, small busbar system, closed channel components, etc., which provide high-quality power supply, temperature and humidity environment protection for various communication network equipment in the cabin.

[0061] Figure 3 A schematic diagram of the power supply architecture of a DC compartment provided in an embodiment of the present application.

[0062] Depend on Figure 3 It can be seen that the small busbar is connected to multiple racks, and the multiple racks are arranged together according to a certain layout.

[0063] The DC cabin provided in the embodiment of the present application can achieve flexible power supply and cooling.

[0064] Figure 4 A schematic diagram of the structure of a small busbar system provided in an embodiment of the present application.

[0065] Depend on Figure 4 It can be seen that the small busbar system includes the straight section of the busbar duct 101, the starting box 102, the plug-in box 102, the elbow, the joint, the mounting bracket (ie, the suspension rod 104) and the end cover and other units and accessories.

[0066] The capacity of the starting box determines the total capacity of the small bus system. Common specifications for the rated current level in the starting box are as follows: Common AC specifications are 100A, 160A, 250A, 400A, 630A (3P); Common DC specifications are 250A, 400A, 630, 800A (2P). The flexible DC cabin configuration of the embodiment of the present application adopts the top-level AC 630A (DC 800A) for configuration. Through reasonable over-allocation of the power distribution capacity, it supports the flexible expansion of the power supply in the DC cabin after the power of the cabinet is increased in the future. Through such a configuration, flexible power supply needs are achieved. For example, when adding a new cabinet, the power supply needs of the new cabinet can be flexibly met by reserving the plug interface in the bus duct; when the power density of the cabinet increases, it only needs to replace the large-capacity circuit breaker and other protective devices to meet the increase in load capacity; some extremely high-power cabinets (such as liquid-cooled cabinets) can use multiple plug-in boxes for simultaneous supply and use.

[0067] In summary, the DC compartment of this application realizes the pooling and flexible allocation of terminal power distribution resources in the DC compartment through the small busbar system to meet the upgrade requirements of high-power cabinets. By adopting the full-matching method of intelligent small busbars, the application of traditional terminal cabinets and cables is replaced to achieve flexible and elastic terminal power distribution.

[0068] In the embodiment of the present application, the DC cabin adopts a small bus system to power the refrigeration equipment and other equipment. By rationalizing the full configuration of the small bus system, the power supply resources can be pooled, the power can be flexibly allocated, and elastic power supply can be achieved; and, a decoupling structural part is provided at the bottom of the refrigeration equipment, and the decoupling design can flexibly replace the refrigeration equipment, thereby achieving elastic cooling.

[0069] Embodiment 2:

[0070] In order to realize flexible cooling of the DC compartment 100 , based on the above embodiment, in the embodiment of the present application, the decoupling structure 30 includes: a preset number of casters 301 , and the preset number of casters 301 are arranged on the bottom surface of the refrigeration equipment 20 .

[0071] In an embodiment of the present application, the decoupling structure 30 includes a preset number of casters 301. In a possible implementation, the preset number may be 4. The preset number of casters 301 are arranged on the bottom surface of the refrigeration device 20. Specifically, they may be respectively arranged at the four corners of the bottom surface of the refrigeration device 20.

[0072] That is to say, the decoupling structure 30 is carefully configured with four casters 301, which are evenly distributed at the four corners of the bottom of the refrigeration device 20, ensuring stable support and flexible movement of the device, so that users can easily adjust the position of the refrigeration device 20 in different scenarios.

[0073] In order to support the refrigeration equipment 20, on the basis of the above embodiments, in the embodiment of the present application, the decoupling structure 30 also includes: a preset number of foot cups 302; the preset number of foot cups 302 are arranged on the bottom surface of the refrigeration equipment 20; the foot cups 302 are used to support the refrigeration equipment 20 when the refrigeration equipment 20 is in a non-moving state.

[0074] In order to support the refrigeration equipment 20, the decoupling structure 30 also includes a preset number of foot cups 302. In a possible implementation, the preset number may be 4. The preset number of foot cups 302 are arranged on the bottom surface of the refrigeration equipment, and specifically, they may be arranged at the four corners of the bottom surface of the refrigeration equipment 20. It should be noted that the installation position of the foot cup 302 and the installation position of the previously mentioned caster 301 maintain a safety distance lower than the preset distance. Such a layout not only ensures the stability of the equipment, but also takes into account the rationality and aesthetics of the spatial layout.

[0075] Embodiment 3:

[0076] In order to achieve flexible cooling of the DC compartment 100, on the basis of the above embodiments, in the embodiment of the present application, the preset number of foot cups 302 are threaded adjustment foot cups;

[0077] The bottom surface of the refrigeration device 20 includes the preset number of first openings; the area of ​​the first openings is not less than the cross-section of the thread of the threaded adjustment foot cup, and is not greater than the cross-section of the double-sided nut of the threaded adjustment foot cup;

[0078] The ends of the threads of the preset number of threaded adjustment feet away from the ground pass through the first opening, and the double-sided nuts of the threaded adjustment feet are located on the bottom surface of the refrigeration device 20.

[0079] In the embodiment of the present application, the foot cup 302 can be a threaded adjustment foot cup, which not only has the function of adjusting the height, but also enhances the stability of the refrigeration device 20. The bottom surface of the refrigeration device 20 is specially reserved with first openings that match the number of threaded adjustment foot cups, and the size of each first opening is precisely calculated: its area is just enough to accommodate the threaded portion of the threaded adjustment foot cup, while ensuring that it is not less than the cross section of the thread to maintain smooth rotation adjustment, and not larger than the cross section of the double-sided nut to prevent the foot cup 302 from shaking or falling off during installation.

[0080] During installation, the threaded portion of the threaded adjustment foot cup passes through the first opening from the end away from the ground, and the double-sided nut is firmly placed under the bottom surface of the refrigeration device 20, which is convenient for adjustment and ensures the compactness and safety of the structure. Such a design not only simplifies the installation process, but also enables the refrigeration device 20 to remain horizontal and stable under different ground conditions.

[0081] It should be noted that the height of the threaded adjustment foot cup can be fine-tuned by the double-sided nut. In a normal state, that is, when the refrigeration device does not need to be moved, the height of the four threaded adjustment foot cups is slightly adjusted to be higher than the height of the caster 301 (for example, 4 to 10 mm), and the weight of the entire refrigeration device 20 is supported and fixed by the four threaded adjustment foot cups.

[0082] Embodiment 4:

[0083] In order to realize flexible cooling of the DC compartment 100, based on the above embodiments, in the embodiment of the present application, the decoupling structure 30 further includes: a preset number of fixing plates 303 for fixing the double-sided nuts; each fixing plate 303 includes a first fixing member 3031, a connecting member 3032 and a second fixing member 3033;

[0084] The connecting member 3032 is located between the first fixing member 3031 and the second fixing member 3033, and is fixedly connected to the first fixing member 3031 and the second fixing member 3033; along the first preset direction, a first fixing hole 30311 is provided on the side of the first fixing member 3031 away from the connecting member 3032, the first fixing hole 30311 is consistent in size with half of the double-sided nut, the first fixing hole 30311 is used to clamp with the double-sided nut, the first fixing hole 30311 is sleeved on the outside of the double-sided nut, and the first fixing hole 30311 is transitionally matched with the double-sided nut;

[0085] The second fixing member 3033 has a second fixing hole 30331 of the same size as the opening at the top of the chassis of the threaded adjustment foot cup 302 ; the second fixing member 3033 is fixed to the opening at the top of the chassis of the threaded adjustment foot cup 302 based on the second fixing hole 30331 and the screw.

[0086] In actual application environments, the double-sided nut of the threaded adjustment foot cup may become unstable due to external factors, which may lead to slight adjustments of the foot cup, and ultimately affect the overall stability of the refrigeration device 20. In order to effectively address this problem, the decoupling structure 30 is specially equipped with a preset number of fixing plates 303, which are specially designed to stabilize the double-sided nut, and can significantly improve the stability and operational reliability of the refrigeration device 20. .

[0087] Specifically, each fixing plate 303 includes three major parts: a first fixing member 3031, a connecting member 3032, and a second fixing member 3033, forming a stable overall structure. The connecting member 3032 is placed between the first fixing member 3031 and the second fixing member 3033, and realizes a firm connection between the three. In the first preset direction, a first fixing hole 30311 is cleverly designed on the side of the first fixing member 3031 away from the connecting member 3032. The size of the first fixing hole 30311 is precisely matched with half of the double-sided nut, forming a tight and flexible clamping relationship. This design allows the first fixing hole 30311 to be easily sleeved on the outside of the double-sided nut to achieve a transition fit, which is both stable and easy to adjust.

[0088] The second fixing member 3033 is provided with a second fixing hole 30331 which is completely consistent with the opening size of the top of the bottom plate of the threaded adjustment foot cup 302. Through the opening and matching screws of this design, the second fixing member 3033 can be accurately and securely connected with the top of the bottom plate of the threaded adjustment foot cup 302, ensuring the stability and reliability of the overall structure.

[0089] This optimized design not only improves the assembly efficiency and accuracy of the decoupling structure 30, but also greatly enhances its stability and durability during use.

[0090] In order to keep the cabinet of the refrigeration equipment as a whole neat and beautiful, a baffle is set at the bottom of the refrigeration equipment. The baffle includes a front baffle and a rear baffle. The main function is to cover the casters, foot cups and other structural parts under the base. In order to support and fix the baffle, the baffle can be supported and fixed by a baffle bracket.

[0091] In other words, the base decoupling structure of the refrigeration equipment mainly includes: bottom plate support, baffle bracket, casters, foot cups and fixing plates. There are 4 casters and 4 foot cups each, located in the 4 corners of the bottom plate support. The main function of the fixing plate is to support and fix the foot cups.

[0092] When the cooling system needs to be upgraded or expanded, the business personnel can follow the following methods and steps:

[0093] Remove the baffles on the front and back sides of the bottom of the refrigeration equipment to expose supporting structures such as the foot cup and casters; remove the fixing plate of the foot cup, and use a wrench to adjust the double-sided nut of the foot cup so that the height of the foot cup is slightly lower than the caster by 3 to 5 mm. At this time, the weight of the refrigeration equipment is borne by the four casters; if there are sealing cotton and cabinet-joining structural parts in the gap between the refrigeration equipment and the adjacent cabinets on both sides, the business personnel will remove the sealing cotton and cabinet-joining structural parts in the gap between the adjacent cabinets on both sides of the refrigeration equipment, and the refrigeration equipment can be flexibly pulled out and replaced through the rollers of the casters at the bottom.

[0094] It is worth noting that in this embodiment, the decoupling design of the bottom structural parts of the cabinet is illustrated by taking the refrigeration equipment as an example, which is also applicable to the other cabinets in the DC compartment. The other cabinets can be flexibly pulled out and replaced through the same decoupling design of the structural parts.

[0100] Embodiment 5:

[0101] In order to realize flexible cooling of the DC cabin 100, based on the above embodiments, in the embodiment of the present application, the DC cabin 100 further includes a cabin body 40; the cabin body 40 includes a plurality of cabinets 50; the refrigeration device 20 is arranged in any cabinet 50;

[0102] The cabinet 50 used to set the refrigeration device 20 among the multiple cabinets 50 includes: a reserved refrigeration interface; the refrigeration interface is used to connect the refrigeration pipeline of the refrigeration device 20 to transmit the cold air of the refrigeration device.

[0103] In the embodiment of the present application, the DC cabin 100 further includes a cabin body 40. The cabin body 40 includes a plurality of cabinets 50 with clear functions to meet various storage or operation requirements. In particular, the refrigeration device 20 is placed in one of the specific cabinets 50 to ensure the temperature control of the environment in the DC cabin 100.

[0104] In order to achieve efficient integration and operation of the refrigeration equipment 20, a refrigeration interface is specially reserved in the cabinet 50 for setting the refrigeration equipment 20. This design not only simplifies the installation process, but also improves the flexibility and scalability of the system. The refrigeration interface accurately connects to the refrigeration pipeline of the refrigeration equipment 20, ensuring that the cold air can be smoothly and efficiently transmitted to every corner of the DC cabin 100, thereby maintaining a constant temperature state in the DC cabin 100 and meeting the environmental requirements of precision equipment.

[0105] Fig. 9A schematic diagram of local features of a DC cabin end door area provided in an embodiment of the present application.

[0106] Depend on Fig. 9 It can be seen that a transparent swingable skylight 60 is provided on the top of the DC cabin, which is not only convenient for ventilation, but also provides a window for observing the internal operation of the DC cabin, allowing natural light to enter and enhancing the brightness of the working environment.

[0107] Below the skylight is the lighting equipment area 70, which ensures that the interior of the DC cabin can obtain sufficient light when needed. The core part of the interior of the DC cabin includes the hot channel area 80 and the cold channel area 90. The hot channel area 80 is mainly used for heat management, while the cold channel area 90 is responsible for cooling. The front baffle 110 is located on the left side of the DC cabin and is used to protect irregularly arranged materials such as wire troughs to avoid clutter. The operation control screen 120 on the outside of the DC cabin provides an intuitive operation interface, through which the user can control the various functions of the equipment. At the same time, the base and cover 150 provide stable support and protection for the equipment.

[0108] Moreover, the front door 130 of the DC compartment adopts a front and back push-pull design, which is convenient to open and saves space. A working status display screen 140 is also embedded on the front door to display the operating status of the equipment in real time, providing great convenience for business personnel.

[0109] Fig.10 A schematic diagram of local features of the top area of ​​a DC cabin provided in an embodiment of the present application.

[0110] Depend on Fig.10 It can be seen that the key component of the small bus system, the start box 102, is set on the top of the DC compartment. It is the starting point of the power distribution of the entire bus system and ensures the stable transmission of electric energy. Next is the single-row bus duct 101 and the plug-in box 103 of the small bus system, which together constitute the main part of the small bus system and are responsible for the distribution and transmission of electric energy.

[0111] In order to ensure the safe operation of the busbar system, the top of the DC compartment is also equipped with a busbar installation and safety protection cover 160. This design effectively prevents external factors from interfering with and damaging the small busbar system, and also reduces the risk of safety accidents. In addition, a single-row cabinet wiring area 170 is planned on the top of the DC compartment. This area provides a clear and orderly path for cable connections between cabinets, avoiding the phenomenon of disorderly cables.

[0112] A high temperature protection plate 180 for the wire duct is also provided on the top of the DC compartment. These protection plates can effectively isolate the high temperature environment and prevent the wire duct from accelerating aging due to the high temperature of the surrounding environment, thereby extending the service life. In addition, the DC compartment also includes a buckle plate 190, and the DC compartment top also includes a cabinet structure 210 to achieve the connection and integration between multiple cabinets or equipment.

[0113] In the embodiment of the present application, by reserving the refrigeration interface, it is convenient to realize the superposition of refrigeration equipment such as inter-row air conditioners and liquid-cooled cabinets, and realize the upgrade of refrigeration elasticity. It solves the problem of high transformation cost and long period caused by the need to replace all air-conditioning terminals, pipelines, valves and other components in the transformation of the traditional DC cabin air-conditioning system. Moreover, it is convenient to add refrigeration equipment and enhance refrigeration elasticity. When the power density is improved, by replacing the original cabinet with the inter-row air conditioner, the refrigeration resource pooling is realized, and the power density of a single cabinet is supported to be 8-15kW. If there are individual ultra-high power cabinets, the end cabinet can be replaced by CDU, and the original cabinet can be replaced by a liquid-cooled cabinet, and liquid cooling technology can be superimposed to support a power density of more than 15kW. For the construction of liquid-cooled cabinet projects, the interface on the primary side and the pipe space on the secondary side are reserved in advance to achieve cooling elasticity and reduce the cost and difficulty of subsequent refrigeration upgrades and renovations.

[0114] The DC cabin of the embodiment of the present application can solve the problem of the existing DC cabin that cannot realize flexible power supply and cooling. Through the rationalization of the full configuration of the intelligent small busbar system, the power supply resources are pooled, and the power is flexibly allocated to realize flexible power supply; flexible cooling is realized by reserving refrigeration pipeline interfaces and decoupling design of inter-row air conditioners. The DC cabin has a breathing effect, which improves the compatibility and adaptability of the DC cabin and reduces the cost and difficulty of later expansion and reconstruction of the DC cabin.

[0115] Embodiment 6:

[0116] In order to realize flexible power supply of the DC compartment 100, on the basis of the above embodiments, in the embodiment of the present application, the small busbar system 10 is an AB path small busbar system.

[0117] The small busbar system 10 in the embodiment of the present application may be an AB path small busbar system.

[0118] It should be noted that when the power demand of the DC compartment 100 increases, it is relatively easy to add additional busbar straight sections or branching devices to match the increased number of cabinets or equipment to be powered, thereby achieving capacity expansion. Moreover, the small busbar system 10 adopts a plug-and-play method, which is quick and convenient to install. Compared with the traditional cable laying method, it can greatly shorten the construction period.

[0119] In order to realize flexible power supply of the DC compartment 100, on the basis of the above embodiments, in the embodiment of the present application, the multiple cabinets 50 are arranged in sequence along a preset direction;

[0120] The number of the small busbar systems 10 is the number of groups of cabinets 50 in the DC compartment 100; wherein the distance between each group of cabinets 50 is less than the preset distance;

[0121] Each small busbar system 10 supplies power to the devices to be powered in different groups of cabinets 50 .

[0122] In an embodiment of the present application, multiple cabinets 50 in a DC compartment 100 are arranged in sequence along a preset direction. In a possible implementation, the DC compartment 100 may include multiple columns of cabinets 50, and each column of cabinets 50 is arranged in sequence along the preset direction. For example, the DC compartment 100 may include two columns of cabinets 50.

[0123] In order to effectively provide flexible power supply, the number of small busbar systems 10 can be the number of groups of cabinets 50 in the DC compartment 100, wherein each row of cabinets can be a group of cabinets. It should be noted that the distance between each group of cabinets 50 is less than the preset distance.

[0124] Each small busbar system 10 supplies power to the devices to be powered in different groups of cabinets 50. If each row of cabinets 50 is a group of cabinets 50, each small busbar system 10 supplies power to the devices to be powered 20 in each row of cabinets 50.

[0125] That is to say, in the embodiment of the present application, there is no need for cross-column power distribution, the capacity meets the design of the power distribution redundant architecture, the wiring is simpler, and the busbar occupies less space.

[0126] Embodiment 7:

[0127] In order to achieve flexible power supply of the DC compartment 100, on the basis of the above embodiments, in the embodiment of the present application, the small bus system 10 includes: a bus duct 101; the bus duct 101 includes a plurality of reserved plug interfaces 1011; the reserved plug interfaces 1011 are used to connect to the newly added equipment 20 to be powered when a new equipment 20 to be powered is added.

[0128] In the embodiment of the present application, the small busbar system 10 includes a busbar duct 101, and the busbar duct 101 has a plurality of reserved plug-in ports 1011 built therein. The design of these plug-in ports fully considers the expansion requirements of the DC compartment 100 in the future.

[0129] Each reserved plug interface 1011 complies with industry standards and safety specifications to ensure fast and safe connection with the newly added power supply device 20. These plug interfaces not only support the connection of various types of power equipment, but also have intelligent recognition functions, which can automatically detect and adapt to the electrical characteristics of the connected equipment to achieve seamless compatibility.

[0130] When a new device 20 to be powered is needed in the DC compartment, such as a server, storage device or other critical infrastructure, the operation and maintenance personnel only need to simply insert the power cable on the device 20 to be powered into the corresponding reserved plug interface 1011 in the bus duct 101 to complete the power access. The entire process does not require complicated wiring work or large-scale system transformation, which greatly improves the efficiency and flexibility of data center operation and maintenance.

[0131] In addition, the reserved plug interface 1011 of the bus duct 101 also has a certain redundancy design to ensure that the continuity and stability of power supply can be maintained in extreme cases (such as damage or failure of a plug interface). This redundant design not only enhances the reliability of the system, but also provides additional protection for the stable operation of the data center.

[0132] It is worth noting that this embodiment uses a DC cabin with refrigeration equipment and closed hot channels as an example to specifically illustrate how to achieve flexible power supply and cooling. Other similar DC cabins achieve flexible power supply and cooling in the same way as this embodiment and are also within the scope of protection of this application.

[0133] Among them, IDC refers to a system with complete equipment (including high-speed Internet access bandwidth, high-performance local area network, safe and reliable computer room environment, etc.), professional management, and complete application service platform.

[0134] The embodiment of the present application is based on the overall goal of improving the flexible power supply and cooling of the DC cabin and achieving flexible compatibility, and designs a DC cabin that can achieve flexible power supply and cooling. Solve the problem that the current DC cabin power supply and cooling configuration is fixed, upgrading and transformation are difficult, and the transformation investment cost is high. One of the technical points of protection is the method and method for realizing flexible power supply in the DC cabin; the flexible DC cabin of the present application, any equipment in the DC cabin, can be flexibly withdrawn through decoupling between the structural parts, and replaced with inter-row air conditioners or other types of cabinets. The refrigeration elastic expansion requirements of the DC cabin are realized, and the problem that the traditional DC cabin has a fixed configuration and poor compatibility and cannot meet the flexible expansion requirements is solved. The second technical point of protection is the key structural parts and decoupling methods for realizing decoupling between cabinets; and, through the reasonable configuration of the small busbar distribution capacity, the terminal distribution resources in the DC cabin are pooled, and the power resources are flexibly allocated to support future cabinet power increase or new cabinets and other scenarios, so as to realize the power supply elasticity in the DC cabin and meet the flexible expansion requirements of the DC cabin. Through the unique structural decoupling design, any equipment in the DC cabin can be flexibly withdrawn and replaced with inter-row air conditioners or other types of cabinets. This enables the DC cabin's cooling upgrade and flexible expansion needs to be met, solving the problem of traditional DC cabins having fixed configurations, poor compatibility, and being unable to meet flexible expansion needs.

[0136] in, Fig.11 Schematic diagram of airflow organization in the DC cabin when the refrigeration equipment is row-to-row air conditioning.

[0137] Depend on Fig.11 It can be seen that the inter-row air conditioners are installed in the preset cabinets of the DC cabin. Each inter-row air conditioner is responsible for the temperature and humidity control of the area near it, and reduces the temperature by blowing cold air to the servers and other IT equipment. The main path of the airflow starts from the air outlet of the inter-row air conditioner. The cold air is blown directly to the air inlet of the server rack, and then becomes hot air after heat exchange inside the server. The hot air is then discharged from the server rack and flows to the hot channel of the cabinet. The hot channel is located between two adjacent cabinet areas, forming a channel specifically for collecting hot air.

[0138] Through this airflow organization method, the DC cabin can effectively separate the cold air from the hot air, avoiding the problem of hot air flowing back to the cold air area, thereby improving the cooling efficiency and reducing energy consumption. At the same time, the precise control of the inter-row air conditioner also ensures that the temperature and humidity of each area in the computer room can be maintained within a stable and appropriate range, providing a good environment for the normal operation of IT equipment.

[0142] Depend on Fig.13 It can be seen that the DC cabin can contain air handling units (AHU) / integrated fluorine pumps. The AHU can drive the air in the DC cabin to exchange heat with the coil inside the unit through the rotation of the fan, and filter impurities in the air to maintain indoor temperature, humidity and air cleanliness by controlling the outlet air temperature and air volume. The integrated fluorine pump system can be used in conjunction with other cooling equipment (such as AHU) to form a more complete cooling solution.
