[0026] The beneficial effects of this utility model are:

[0027] The electrical control cabinet of this utility model has an inlet terminal in the inlet / outlet compartment for connecting to external high-voltage power, and an outlet line in the inlet / outlet compartment leading out of the electrical control cabinet through the outlet port for easy electrical connection to various servers; the transformer reduces the voltage of the high-voltage power introduced by the high-voltage inlet terminal and sends it to the low-voltage terminal block in the low-voltage compartment for power supply to the auxiliary power components, gateways and other low-voltage power components of the container data center; the inverter in the inverter compartment is used to adjust the speed of the cooling fan. The electrical control cabinet of this utility model has several advantages. First, the incoming and outgoing line compartment is located at the top, while the low-voltage room and frequency converter room are located below it. This allows each functional room to make full use of the vertical space, reducing the floor space of the control cabinet while meeting various functional requirements, thus satisfying the compact structure requirements of containerized data centers. Second, the high-voltage power in the incoming and outgoing line compartment is stepped down by an internal transformer before being introduced into the low-voltage room, reducing the number of external cables. Furthermore, the fact that both the low-voltage room and the frequency converter room are located below the incoming and outgoing line compartment clearly separates the high-voltage and low-voltage incoming and outgoing lines of the control cabinet vertically, improving the convenience of fault diagnosis and maintenance. Finally, placing the frequently faulty low-voltage room in front of the less frequently faulty frequency converter room further enhances the convenience of maintenance.

[0028] The containerized data center of this invention, by adopting the above-mentioned electrical control cabinet, facilitates the layout of its internal structures and makes fault diagnosis and maintenance easier. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0054] This embodiment provides an electrical control cabinet and a containerized data center, such as Figure 1and Figure 2 As shown, the containerized data center includes a container 700, multiple servers 300, multiple heat exchange pools 500, an oil pump assembly 800, an oil tank 600, and a cooling fan 200. The container 700 forms the installation space and includes one or more container doors. Multiple servers 300, multiple heat exchange pools 500, an oil tank 600, an oil pump assembly 800, and a cooling fan 200 are all installed inside the container 700. Each server 300 is located in a heat exchange pool 500. The oil tank 600 stores oil for heat exchange. The oil pump assembly 800 drives the oil to circulate between the heat exchange pools 500 and the oil tank 600, thereby cooling each server 300. The cooling fan 200 is installed above the oil tank 600 to cool the oil inside. In this embodiment, the speed of the cooling fan 200 can be adjusted according to the oil temperature in the oil tank 600. Figure 2 As shown, the containerized data center also includes multiple power distribution units 400. Each server 300 is configured with one power distribution unit 400, and each power distribution unit 400 is connected to the power control cabinet 100 and distributes power to one server 300. In this embodiment, the oil pump assembly 800, cooling fan 200, etc., are auxiliary power components of the containerized data center. It is understood that the containerized data center also includes other auxiliary power equipment such as lighting switches, which will not be described in detail here.

[0055] like Figure 1 As shown, the container 700 has a roughly rectangular cross-section. A first container door 710 is positioned at the midpoint of each of the two long sides of the rectangle. An oil bath 600 and a cooling fan 200 are arranged on one side of the first container door 710, while a server 300 and a heat exchange tank 500 are arranged on the other side. Multiple servers 300 are arranged in two rows, with each row of servers 300 attached to one of the two long sides of the rectangle. A second container door 720 is also positioned on the short side of the rectangle, between the two rows of heat exchange tanks 500.

[0056] In related technologies, containerized data centers, as described above, require at least multiple electrical control cabinets, including low-voltage cabinets, high-voltage cabinets, and frequency converter cabinets. On the one hand, multiple electrical control cabinets occupy a large area, thus affecting the layout of other structures within the container. On the other hand, multiple electrical control cabinets lead to complex wiring connections, increasing the difficulty of troubleshooting and maintenance.

[0057] In this regard, such as Figure 3As shown, this embodiment also provides an electrical control cabinet 100, which includes a cabinet body 10. The cabinet body 10 includes an inlet / outlet cable compartment 20, a low-voltage cable compartment 30, and a frequency converter compartment 40. At least one inlet terminal 21 and at least one outlet port 27 for supporting output lines are installed on the inlet / outlet cable compartment 20. The inlet terminal 21 of the inlet / outlet cable compartment 20 is used to connect to external high-voltage power (i.e., AC mains power). The output lines of the inlet / outlet cable compartment 20 are led out of the electrical control cabinet through the outlet port 27 for easy electrical connection with the power lines of each server 300. A transformer 28 (see reference) is also provided inside the inlet / outlet cable compartment 20. Figure 6 The transformer 80 is electrically connected to the incoming terminal 21. A low-voltage wiring harness 31 is installed in the low-voltage room 30, and is electrically connected to the transformer 28, ensuring that low-voltage power can be output from the low-voltage wiring harness 31 to power components (such as gateways) using low-voltage power within the container 700. In addition, the low-voltage room 30 also has auxiliary wiring ports for connecting auxiliary power components of the containerized data center. The incoming / outgoing line room 20 is located above, while the low-voltage room 30 and the frequency converter room 40 are both located below the incoming / outgoing line room 20, with the low-voltage room 30 located in front of the frequency converter room 40. A frequency converter 41 is installed in the frequency converter room 40, and is connected to the cooling fan 200 for speed control. Optionally, the frequency converter room 40 may contain one, two, or more frequency converters 41.

[0058] In this embodiment, the electrical control cabinet 100 has several advantages. First, the low-voltage room 30 and the frequency converter room 40 are located below the incoming and outgoing line room 20, allowing each functional room to make full use of the vertical space. This reduces the floor space of the electrical control cabinet 100 while meeting the functional requirements, thus satisfying the need for a compact structure in a containerized data center. Second, the high-voltage power in the incoming and outgoing line room 20 is stepped down by the transformer 28 and then passes through the partition between the incoming and outgoing line room 20 and the low-voltage room 30 (i.e., the first partition 15 below) to enter the low-voltage room 30, thus reducing the number of external cables. Furthermore, since both the low-voltage room 30 and the frequency converter room 40 are located below the incoming and outgoing line room 20, the high-voltage and low-voltage incoming and outgoing lines of the electrical control cabinet 100 are separated vertically, improving the convenience of troubleshooting and maintenance. Third, placing the low-voltage room 30, which experiences more frequent faults, at the front, and the frequency converter room 40, which experiences fewer faults, at the rear, further enhances the convenience of maintenance.

[0059] In this embodiment, the electrical control cabinet 100 includes a frame 11 and multiple plates. The multiple plates surround the outside of the frame 11 and are disposed inside the frame 11, thereby forming an inlet / outlet wiring compartment 20, a low-voltage wiring compartment 30, and a frequency converter compartment 40. Optionally, the frame 11 is assembled from high-strength steel using fasteners and / or welding processes. Specifically, as shown... Figure 3As shown, the frame 11 includes multiple columns 112 and multiple crossbeams 111. The columns 112 extend vertically, and the crossbeams 111 are arranged and connect adjacent columns 112. The low-voltage room 30 and the frequency converter room 40 are separated by a second partition 16. A first partition 15 is provided at the bottom of the inlet / outlet room 20 (see reference). Figure 7 (as shown), thereby achieving separation from the weak current room 30 and the frequency converter room 40.

[0060] like Figure 4 As shown, the front side of the frame 11, from top to bottom, includes a lifting ring 135, a top plate 134, a front upper door 121, a front lower door 122, a front sealing plate 123, and a bottom plate 133. The top plate 134 and bottom plate 133 are respectively installed at the top and bottom of the frame 11. The lifting ring 135 is installed on the top plate 134 and is used to cooperate with external lifting equipment to lift the electrical control cabinet 100. The front upper door 121 is located at the front of the inlet / outlet compartment 20. The front upper door 121 is used to open and close the inlet / outlet compartment 20 to facilitate user operation of the components inside. One end of the front upper door 121 is connected to the frame 11 via a concealed hinge, and the other end is fixed to the frame 11 via a door lock 64. The number and arrangement of the concealed hinges and door lock 64 can be flexibly set according to requirements. In this embodiment, the front upper door 121 is equipped with electrical components such as indicator lights 63, a control panel 62, and an instrument 61. An opening is provided on the upper front door 121, through which the incoming line switch 24 can be exposed for user operation. It is understood that in other embodiments, the types of electrical components on the upper front door 121 can be flexibly configured according to requirements. The front sealing plate 123 is fixedly connected to the frame 11 and is located in the lower area of ​​the front side of the low-voltage room 30. The lower front door 122 is located in the upper area of ​​the front side of the low-voltage room 30 and is used to open and close the low-voltage room 30 to facilitate user operation of the components inside. One end of the lower front door 122 is connected to the frame 11 via a concealed hinge, and the other end is fixed to the frame 11 via a door lock 64. In this embodiment, a third ventilation window 1221 is provided on the lower front door 122 for ventilation and heat dissipation of the low-voltage room 30. A left side plate 131 and a right side plate 132 are respectively installed on the left and right sides of the frame 11.

[0061] like Figure 5 As shown, a rear upper plate 142 and a rear sealing plate 141 are provided on the rear side of the frame 11. The rear sealing plate 141 corresponds from bottom to top to the inverter compartment 40 and part of the inlet / outlet cable compartment 20. That is, the rear sealing plate 141 forms the rear side wall of the inverter 41 and part of the rear side wall of the inlet / outlet cable compartment 20. The rear upper plate 142 is located above the rear sealing plate 141 and forms another part of the rear side wall of the inlet / outlet cable compartment 20. Figure 5As shown, a first opening is provided on the rear side wall of the inlet / outlet compartment 20, and a rear upper door 143 is installed at the first opening. Opening and closing the rear upper door 143 facilitates the inspection and maintenance of the components inside the inlet / outlet compartment 20 from the rear. A second opening is provided on the rear side wall of the inverter compartment 40, and a rear lower door 144 is installed at the second opening. Opening and closing the rear lower door 144 facilitates the inspection or maintenance of the inverter 41 inside the inverter compartment 40. In this embodiment, both the first and second openings are located on the rear sealing plate 141. Optionally, the rear upper door 143 includes a plate 1431, a handle 1432, and a latch 1433, wherein the latch 1433 is installed on the plate 1431 to fix the plate 1431 to the frame 11 or the rear sealing plate 141, and the handle 1432 is connected to the outside of the plate 1431 for easy gripping and operation by the user. Optionally, the latch 1433 can be any existing structure capable of fixing the panel. The specific number of handles 1432 and latches 1433 on the upper rear door 143 can be set as needed and is not limited here. The structure of the lower rear door 144 is the same as that of the upper rear door 143, and will not be described again.

[0062] like Figure 6 As shown, the incoming / outgoing line compartment 20 also includes an incoming busbar 22, current transformers 23, an incoming switch 24, a busbar assembly 25, and an outgoing switch 26. The incoming terminals 21 are partially located inside the incoming / outgoing line compartment 20 and partially outside, and are divided into three phases. Each phase's incoming terminal 21 is connected to one phase's incoming busbar 22. The current transformers 23 pass through the incoming busbar 22 from top to bottom and are electrically connected to the incoming terminal of the incoming switch 24. The incoming terminal of the busbar assembly 25 is connected to the outgoing terminal of the incoming switch 24, and the outgoing switch 26 is connected to the outgoing terminal of the busbar assembly 25. The output line is connected to the outgoing terminal of the outgoing switch 26, passes through the outgoing port 27, extends to the outside of the electrical control cabinet 100, and is ultimately electrically connected to each power distribution unit 400. The current transformers 23, mounted on the incoming busbar 22, are used to detect the current on the incoming busbar 22. Optionally, the outgoing port 27 can be a gland connector, which is an insulated connecting component used to support the output cable leading out from the inlet / outlet compartment 20. For example... Figure 3 As shown, a grounding busbar assembly 50 is also installed in the incoming and outgoing line compartment 20. The grounding busbar assembly 50 is fixed on the column 112 and is used for grounding.

[0063] In this embodiment, the wires leading from the transformer 28 pass through the first partition 15 and enter the weak current room 30, connecting to the weak current terminal block 31. In actual use, holes can be made on the left and / or right walls of the weak current room 30 to allow wires between the weak current terminal block 31 and the weak current components to pass through. The electrical control cabinet 100 also includes an auxiliary power switch 32, which is located inside the weak current room 30. The auxiliary power switch 32 is electrically connected to the output terminal of the incoming terminal 21, and the frequency converter 41 is electrically connected to the auxiliary power switch 32. That is, the switch for controlling the frequency converter 41 is located inside the weak current room 30, allowing for convenient operation of the frequency converter 41 by opening the front lower door 122. In this embodiment, the wire between the auxiliary power switch 32 and the output terminal of the incoming switch 24 passes through the first partition 15. Furthermore, other auxiliary electrical components of the containerized data center, such as the oil pump assembly 800 and lighting, are also electrically connected to the auxiliary power switch 32. It is understandable that the auxiliary power switch 32 includes a main switch and multiple branch switches. Each branch switch is used to control the opening and closing of an auxiliary power component, while the main switch can be used to simultaneously turn on or segment multiple auxiliary power components.

[0064] like Figure 7 As shown, in this embodiment, the bus assembly 25 includes a bus body 251 and an isolation cover 252. The inlet terminal of the bus body 251 is electrically connected to the inlet switch 24, and the outlet terminal of the bus body 251 is electrically connected to the outlet switch 26. The isolation cover 252 covers the bus body 251. Since the inlet and outlet terminals in this embodiment do not have separate chambers, the isolation cover 252 can be used to insulate and separate the inlet and outlet terminals within the inlet / outlet chamber 20, thereby ensuring the safety of the electrical control cabinet 100 and protecting the bus body 251. Optionally, the isolation cover 252 can be made of a transparent material.

[0065] like Figure 3As shown, the incoming / outgoing line compartment 20 is equipped with multiple incoming line terminals 21, which are respectively located on the left and right side walls of the compartment 20. This allows for selection of the incoming line terminal 21 on different side walls to connect according to the specific direction of the mains power supply, providing greater flexibility. In this embodiment, a portion of the left side plate 131 constitutes the left side wall of the incoming / outgoing line compartment 20, and a portion of the right side plate 132 constitutes the right side wall. In other embodiments, the multiple incoming line terminals 21 can be located on either the left side wall or the right side wall of the compartment 20. In other embodiments, the incoming / outgoing line compartment 20 may have only one incoming line terminal 21, which can be located on either the left or right side wall. In yet another embodiment, the incoming / outgoing line compartment 20 may have two incoming line terminals 21, which can be located on either the left or right side wall, or one on the left and the other on the right side wall.

[0066] like Figure 4 As shown, multiple outgoing ports 27 are installed on the incoming / outgoing cable compartment 20, located on the left and right walls of the compartment. Some output cables can pass through the outgoing ports 27 on the left wall to connect to the power distribution unit 400 of the server 300 located to the left of the electrical control cabinet 100, while other output cables pass through the outgoing ports 27 on the right wall to connect to the power distribution unit 400 of the server 300 located to the right of the integrated electrical control box 100. This avoids the tangled wiring inside the containerized data center and improves the convenience of assembly and subsequent maintenance.

[0067] like Figure 6 As shown, the outgoing switch 26 has a ribbed layout. In this embodiment, the outgoing switch 26 extends vertically, and the output ports of the outgoing switch 26 are symmetrically distributed left and right. Therefore, the output line connected to the output port on the left side of the outgoing switch 26 extends out of the control cabinet 100 from the left outgoing port 27, and the output line connected to the output port on the right side of the outgoing switch 26 extends out of the control cabinet 100 from the right outgoing port 27. This avoids the output lines inside the ingoing and outgoing cable compartment 20 from crossing and messing up, and improves the convenience of assembly and subsequent maintenance.

[0068] In this embodiment, combined with Figure 4 and Figure 6 The incoming terminal 21 is installed in the upper area of ​​the incoming / outgoing line compartment 20, and the outgoing port 27 is installed in the lower area of ​​the incoming / outgoing line compartment 20. This allows the incoming and outgoing lines of the incoming / outgoing line compartment 20 to be staggered vertically, making full use of the vertical space and further reducing the footprint of the electrical control cabinet 100, making it suitable for use in containerized data centers with relatively compact spaces.

[0069] like Figure 5 and Figure 7 As shown, a connecting hole is provided on the first partition 15 between the inverter room 40 and the incoming / outgoing line room 20 to connect the inverter room 40 and the incoming / outgoing line room 20. A first ventilation window 1421 is provided on the rear side wall of the incoming / outgoing line room 20, and a second ventilation window 1411 is provided on the rear side wall of the inverter room 40. The electrical control cabinet 100 also includes a drive fan 29, which is configured to drive airflow to enter through the second ventilation window 1411 and exit through the first ventilation window 1421. With this configuration, the airflow first passes through the inverter 41, which has higher heat dissipation requirements, and then enters the incoming / outgoing line room 20 through the connecting hole on the first partition 15 to absorb heat from the components inside the incoming / outgoing line room 20. That is, a single drive fan 29 can dissipate heat from the inverter room 40 and the incoming / outgoing line room 20, which have different heat dissipation requirements. The structure is simple and the cost is low. Since the heat dissipation requirements of the weak current room 30 are lower, the heat dissipation requirements can be met by natural convection through the third ventilation window 1221 on the front lower door 122. In this embodiment, the drive fan 29 is installed inside the inlet / outlet cable compartment 20.

[0070] like Figure 7 As shown, an air guide plate 42 is installed inside the inverter compartment 40. The air guide plate 42 is inclined, with one end of the air guide plate 42 away from the weak current room 30 located below the second ventilation window 1411, and the end of the air guide plate 42 closer to the weak current room 30 higher than the end away from the weak current room. The inverter 41 is located above the air guide plate 42. Since the airflow temperature entering the inverter compartment 40 from the second ventilation window 1411 is low, the airflow may meander below the inverter compartment 40. By setting the air guide plate 42, the airflow can be better guided upward, avoiding the airflow from meandering below the inverter compartment 40, thereby improving the cooling efficiency. Optionally, the air guide plate 42 can be fixed to the frame 11 by welding or fastener connection.
