Description

Technical Field

[0001] This application belongs to the field of power supply technology, specifically relating to a mobile emergency rack cabinet for data centers. Background Technology

[0002] A row cabinet is typically fixed at the end of a row of cabinets and is a device that provides power distribution management or network cabling services for cabinets arranged in rows or divided by functional areas.

[0003] In related technologies, when the fixed-installation cabinet is damaged due to reasons such as circuit breaker failure, busbar burnout, or monitoring system failure, it cannot supply power to the cabinet normally, causing the cabinet to be unusable. Only after the cabinet is repaired can the cabinet be used normally, which may easily lead to signal transmission interruption or data loss. Utility Model Content

[0004] The purpose of this application is to provide a mobile emergency rack cabinet for data centers, which can solve the problem in related technologies where racks cannot be used normally due to malfunctions or damage to fixed rack cabinets.

[0005] This application provides a mobile emergency rack cabinet for data centers. The mobile emergency rack cabinet includes a cabinet body, with casters at the bottom of the cabinet body. The cabinet body is provided with an input connector and at least two output connectors. The input connector is used for electrical connection to a power source, and each of the output connectors is electrically connected to the input connector. Each of the output connectors is used for electrical connection to a load.

[0006] In this embodiment, when the fixed-positioned column head cabinet fails, the mobile emergency column head cabinet of the data center can be moved to the corresponding load location. By connecting the input connector to the power supply and the output connector to the load, a power supply channel can be quickly established, allowing the load to restore power supply in a short time, reducing equipment downtime and data loss risk caused by power outages, and ensuring continuous operation of the load.

[0007] Furthermore, the mobile emergency rack cabinets in data centers are not limited by fixed locations and can be flexibly deployed in different areas according to actual needs. When a fixed rack cabinet in a certain area needs maintenance, it can be replaced by a mobile emergency rack cabinet in the data center to meet the power supply needs of the load.

Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The mobile emergency data center cabinet provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0013] refer to Figures 1-6 As shown in the illustration, an embodiment of this application provides a mobile emergency data center cabinet, which may include a cabinet 100, such as... Figure 1 As shown, the bottom of the cabinet 100 may be equipped with casters 200. The cabinet 100 may be equipped with an input connector 300 and at least two output connectors 400. The input connector 300 can be used for electrical connection to a power supply. Each output connector 400 can be electrically connected to the input connector 300, and each output connector 400 can be used for electrical connection to a load 1700. Here, the load 1700 can be a server rack or a server.

[0014] Optionally, the input connector 300 can be electrically connected to a power source via the first cable described below, such as... Figure 2 As shown, each output connector 400 can be electrically connected to a different load 1700 via the second cable 1800 described below. The input connector 300 and the output connector 400 can both be located on the same side wall of the cabinet 100, or the input connector 300 and the output connector 400 can be located on two opposite side walls or two adjacent side walls of the cabinet 100, respectively.

[0015] In this embodiment, when the fixed column head cabinet fails, the mobile emergency column head cabinet of the data center can be moved to the corresponding load 1700. By connecting the input connector 300 to the power supply and the output connector 400 to the load 1700, a power supply channel can be quickly established, allowing the load 1700 to restore power supply in a short time. This reduces equipment downtime and data loss risk caused by power outages, and ensures the continuous operation of critical loads such as servers and network equipment.

[0016] Furthermore, the mobile emergency rack unit in the data center is not limited by a fixed location and can be flexibly deployed in different areas of the server room according to actual needs. When a fixed rack unit in a certain area needs maintenance, it can be replaced by the mobile emergency rack unit to meet the power supply requirements of load 1700. In addition, since the cabinet 100 is equipped with at least two output connectors 400, the mobile emergency rack unit can provide power to multiple loads 1700 simultaneously.

[0017] In this embodiment, the cabinet 100 can be a cuboid structure, and the dimensions of the cabinet 100 can be: 1000mm × 800mm × 2000mm (height).

[0018] Optionally, the bottom of the cabinet 100 may be provided with four casters 200. The four casters 200 may be located at the corners of the bottom of the cabinet 100. This arrangement can improve the stability and balance of the cabinet 100 when it moves.

[0019] For example, the casters 200 can be locking casters. Once the cabinet 100 has moved to the desired position, the casters 200 can be locked to prevent them from continuing to rotate, thus keeping the cabinet 100 in the desired position. Here, the four casters 200 can support a weight of 1.5 tons.

[0020] In an optional embodiment, both the input connector 300 and the output connector 400 can be aviation plugs. This configuration reduces the likelihood of poor contact or loosening between the input connector 300 and the first connector described below, and between the output connector 400 and the second connector described below, during frequent cable plugging and unplugging or long-term use. This improves the stability of power transmission and allows for quick plugging and unplugging, facilitating emergency power switching within 10 minutes.

[0021] Optionally, the input connector 300 may include a positive connector 310 and a negative connector 320, both of which can be aviation plugs. Further, the input connector 300 may include multiple positive connectors 310 and multiple negative connectors 320 to increase the input current carrying capacity.

[0022] For example, both the positive connector 310 and the negative connector 320 can be industrial-grade high-current DC aviation plugs, such as the ITT Cannon CDM1000 series (or equivalent) aviation plugs. Specifically, they can be aviation plugs with a rated current of 1000A and a short-time overload current of 1200A. These plugs have a voltage rating of DC 1500V, a protection rating of IP67, and an effective mating / removal lifespan of greater than or equal to 500 cycles. They can be matched with 2×240mm² double-strand high-temperature resistant silicone cables, with a single cable current carrying capacity of 700A@40℃, meaning that under an ambient temperature of 40℃, a single 240mm² cable can carry a current of 700A@40℃. 2 The cable can safely carry a maximum current of 700A.

[0023] The output connector 400 can be a high-density DC aviation plug, such as the Amphenol LTW series or the Souriau SUNBURST 8STA series. Specifically, the output connector 400 can be an aviation plug with a rated current of 63A. This aviation plug has a voltage rating of DC 1000V, a protection rating of IP65, and can be matched with 16mm² flame-retardant copper core cable. The current carrying capacity of the flame-retardant copper core cable can be greater than or equal to 70A@40℃, that is, under an ambient temperature of 40℃, the flame-retardant copper core cable can safely carry a maximum current of 70A.

[0024] In optional embodiments, such as Figure 6 As shown, the cabinet 100 may have an internal space 110, which may house electrical components electrically connected to the input connector 300 and / or the output connector 400. These electrical components may include, as described below, the main control switch 600, the branch control switch 700, the surge protection module 800, the insulation monitoring module 1000, etc.

[0025] Optionally, the mobile emergency rack cabinet for data centers may also include a first temperature sensing element, a heat dissipation component, and a control module.

[0026] The first temperature sensing element can be disposed within the internal space 110 and can be used to detect the temperature of the internal space 110; the heat dissipation assembly can be disposed on the cabinet 100 and can be used to dissipate heat from the internal space 110; the control module can be communicatively connected to the first temperature sensing element and the heat dissipation assembly, and the control module can be used to control at least a portion of the heat dissipation assembly to dissipate heat from the internal space 110 when the first temperature sensing element detects that the temperature of the internal space 110 is greater than or equal to a first preset temperature. For example, the first temperature sensing element can be a temperature sensor.

[0027] Since multiple electrical components are concentrated within the internal space 110, heat is generated during operation. If this heat cannot be dissipated in time, the temperature of the internal space 110 will become too high, potentially leading to performance degradation or even damage to the electrical components. In this embodiment, a first temperature detection element monitors the temperature of the internal space 110 in real time. When the temperature is greater than or equal to a first preset temperature, the control module controls at least a portion of the heat dissipation component to dissipate heat from the internal space 110, thus timely removing heat from the cabinet 100 and preventing overheating-induced malfunctions of the data center mobile emergency cabinet, ensuring its continuous and stable operation. Furthermore, the control module only controls at least a portion of the heat dissipation component to operate when the first temperature detection element detects that the temperature of the internal space 110 is greater than or equal to the first preset temperature. When the temperature is lower than the first preset temperature, the heat dissipation component is in a shutdown state, thereby avoiding unnecessary energy consumption, reducing the overall energy consumption of the data center mobile emergency cabinet, and also reducing noise during operation.

[0028] In other embodiments, the mobile emergency rack cabinet for the data center may not include the first temperature detection element. The heat dissipation component may continuously dissipate heat from the internal space 110, or the heat dissipation component may dissipate heat from the internal space 110 at intervals.

[0029] In optional embodiments, such as Figure 6 As shown, an air inlet channel 120 can be provided on the bottom wall of the cabinet 100, and an air outlet channel 130 can be provided on the top wall of the cabinet 100. The internal space 110 can be connected to the air inlet channel 120 and the air outlet channel 130 respectively.

[0030] The heat dissipation assembly may include a first fan assembly 1900 and a second fan assembly 2000. The first fan assembly 1900 may be disposed at the bottom of the cabinet 100, and the second fan assembly 2000 may be disposed at the top of the cabinet 100.

[0031] When the first temperature detection element detects that the temperature of the internal space 110 is greater than or equal to the first preset temperature and less than the second preset temperature, the control module can control the second fan assembly 2000 to work so that cold air can enter the internal space 110 from the air inlet channel 120, cool the internal space 110 and then be discharged from the air outlet channel 130.

[0032] When the first temperature sensing element detects that the temperature of the internal space 110 is greater than or equal to the second preset temperature, the control module can control both the first fan assembly 1900 and the second fan assembly 2000 to operate. This setting increases the air intake volume, thereby improving the cooling effect on the internal space 110.

[0033] In this embodiment, by setting a first temperature detection element and controlling the working state of the first fan assembly 1900 and the second fan assembly 2000 according to different temperature thresholds, precise hierarchical management of the temperature of the internal space 110 of the cabinet 100 is achieved. When the temperature of the internal space 110 is between the first preset temperature and the second preset temperature, only the second fan assembly 2000 is activated, thus meeting the heat dissipation requirements while avoiding unnecessary energy consumption. When the temperature reaches or exceeds the second preset temperature, both the first fan assembly 1900 and the second fan assembly 2000 are activated simultaneously, which can increase the air intake to reduce the temperature of the internal space 110 more quickly and effectively, preventing damage to electrical components due to excessive temperature.

[0034] Here, the first preset temperature can be 25℃, and the second preset temperature can be 40℃.

[0035] In other embodiments, the heat dissipation assembly may also include only the first fan assembly 1900 or the second fan assembly 2000.

[0036] In some embodiments, such as Figure 6 As shown, a first air outlet 160 can be provided on the top of the cabinet 100. The air outlet duct 130 is connected to the internal space 110 through the first air outlet 160. The second fan assembly 2000 can be set at the first air outlet 160. Compared with the method of setting the second fan assembly 2000 inside or above the air outlet duct 130, this setting allows the airflow generated by the second fan assembly 2000 to directly act on the internal space 110, which can significantly improve the cooling efficiency of the internal space 110 and is more conducive to achieving rapid cooling of the internal space 110.

[0037] Optionally, the top of the cabinet 100 may be provided with at least two first air outlets 160, and the second fan assembly 2000 may include at least two second fans 2010. Each second fan 2010 may be respectively and correspondingly set at each of the first air outlets 160. This arrangement can further achieve rapid cooling of the internal space 110.

[0038] In optional embodiments, such as Figure 6As shown, a first heat dissipation channel 140 and a first control board 141 can be provided inside the side wall of the cabinet 100. The first heat dissipation channel 140 can be located close to the input connector 300 and the output connector 400 to cool them. The first control board 141 can be located between the first heat dissipation channel 140 and the air inlet channel 120, and can switch between a first position and a second position. When the first control board 141 is in the first position, the first heat dissipation channel 140 is connected to the air inlet channel 120, allowing cool air to enter the first heat dissipation channel 140, thereby cooling the input connector 300 and the output connector 400 to prevent them from overheating and being damaged. When the first control board 141 is in the second position, the first control board 141 can cut off the first heat dissipation channel 140 and the air inlet channel 120 so that cold air cannot enter the first heat dissipation channel 140, thereby avoiding the temperature of the input connector 300 and the output connector 400 being too low, and allowing more cold air to enter the internal space 110.

[0039] In other embodiments, the first heat dissipation channel 140 and the first control board 141 may not be provided in the side wall of the cabinet 100.

[0040] In an optional embodiment, the data center mobile emergency rack cabinet may further include a second temperature detection element and at least two third temperature detection elements. The second temperature detection element may be located near the input connector 300 and may be used to detect the temperature of the input connector 300. Each of the third temperature detection elements may be located near each output connector 400 and may be used to detect the temperature of each output connector 400.

[0041] Both the second and third temperature sensing elements can communicate with the control module. When the second temperature sensing element detects that the temperature of the input connector 300 is greater than or equal to a third preset temperature, and / or when the third temperature sensing element detects that the temperature of the input connector 300 is greater than or equal to a fourth preset temperature, the control module can control the first control board 141 to switch to a first position, thereby connecting the first heat dissipation channel 140 with the air inlet channel 120. This allows cold air to enter the first heat dissipation channel 140 through the air inlet channel 120 and cool the input connector 300 and the output connector 400. Here, both the third and fourth preset temperatures can be 25°C.

[0042] In this embodiment, the position of the first control board 141 can be automatically controlled through the communication connection between the second and third temperature detection elements and the control module, so that the entire heat dissipation process can be automated without manual intervention, and can respond to temperature changes in a timely manner to ensure the normal operation of the mobile emergency rack cabinet in the data center.

[0043] In other embodiments, the data center mobile emergency rack may not include the second and third temperature detection elements. The operator can manually control the position of the first control panel 141.

[0044] Optionally, the first control panel 141 may include a first position adjusting member and a first closing plate. The first position adjusting member may be disposed on the cabinet 100 and connected to the first closing plate. The first position adjusting member may be communicatively connected to a control module. The control module may control the first position adjusting member to drive the first closing plate to switch between a first position and a second position, so that the first heat dissipation channel 140 is connected to the air inlet channel 120, or so that the first closing plate cuts off the connection between the first heat dissipation channel 140 and the air inlet channel 120. For example, a first groove may be provided on the side wall of the cabinet 100. When the first closing plate is in the first position, the first closing plate is located in the first groove to avoid the first heat dissipation channel 140, thus allowing the first heat dissipation channel 140 to connect with the air inlet channel 120. Alternatively, the first closing plate may be a folding plate, and the first position adjusting member may drive the second closing plate to fold and unfold. The first position adjusting member may be an electric push rod. In optional embodiments, such as Figure 6 As shown, a second heat dissipation channel 150 and a second control board 151 can also be provided inside the side wall of the cabinet 100.

[0045] The second heat dissipation channel 150 can be equipped with cables that are electrically connected to electrical components. This allows the cables to be arranged in a centralized manner within the channel, preventing them from being exposed randomly in the internal space 110, making the internal space 110 more concise, and facilitating cable maintenance by operators.

[0046] The second control board 151 can be positioned between the second heat dissipation channel 150 and the air intake channel 120, and can switch between a third position and a fourth position. When the second control board 151 is in the third position, the second heat dissipation channel 150 is connected to the air intake channel 120, allowing cool air to enter the second heat dissipation channel 150 to cool the cables. When the second control board 151 is in the fourth position, it disconnects the second heat dissipation channel 150 from the air intake channel 120, preventing cool air from entering the second heat dissipation channel 150, thus allowing more cool air to enter the internal space 110.

[0047] In other embodiments, the second heat dissipation channel 150 and the second control board 151 may not be provided in the side wall of the cabinet 100.

[0048] In an optional embodiment, the data center mobile emergency rack cabinet may further include a fourth temperature detection element, which may be disposed within the second heat dissipation channel 150 and may be used to detect the temperature within the second heat dissipation channel 150.

[0049] The fourth temperature detection element can communicate with the control module. When the fourth temperature detection element detects that the temperature in the second heat dissipation channel 150 is greater than or equal to the fifth preset temperature, the control module can control the second control board 151 to switch to the third position so that the second heat dissipation channel 150 is connected to the air inlet channel 120.

[0050] In this embodiment, the position of the second control board 151 can be automatically controlled through the communication connection between the fourth temperature detection element and the control module, so that the entire heat dissipation process can be automated without manual intervention, and can respond to temperature changes in a timely manner to ensure the normal operation of the mobile emergency rack cabinet in the data center.

[0051] In other embodiments, the data center mobile emergency rack may also not include a fourth temperature detection element, and the operator can manually control the position of the second control board 151.

[0052] Optionally, the second control panel 151 may include a second position adjustment member and a second sealing plate. The second position adjustment member may be disposed on the cabinet 100 and connected to the second sealing plate. The second position adjustment member may be communicatively connected to a control module. The control module may control the second position adjustment member to drive the second sealing plate to switch between a third position and a fourth position, so that the second heat dissipation channel 150 is connected to the air inlet channel 120, or so that the second sealing plate cuts off the connection between the second heat dissipation channel 150 and the air inlet channel 120. For example, a second groove may be provided on the side wall of the cabinet 100. When the second sealing plate is in the third position, the second sealing plate is located in the second groove to avoid the second heat dissipation channel 150, so that the second heat dissipation channel 150 is connected to the air inlet channel 120. Alternatively, the second sealing plate may be a folding plate, and the second position adjustment member may drive the second sealing plate to fold and unfold. The second position adjustment member may be an electric push rod.

[0053] In some embodiments, such as Figure 6 As shown, a second air outlet 170 can also be provided on the top of the cabinet 100. The second air outlet 170 can be located above the air outlet channel 130 and connected to the air outlet channel 130 to facilitate airflow discharge.

[0054] Optionally, the top of the cabinet 100 may be provided with at least two second air outlets 170, each of which can be connected to the air outlet duct 130, which helps to improve air outlet efficiency.

[0055] Further optionally, at least a portion of the second air outlet 170 is opposite to the first air outlet 160, which facilitates the rapid discharge of hot air from the internal space 110. Furthermore, at least a portion of the second air outlet 170 may be opposite to the first heat dissipation channel 140 and the second heat dissipation channel 150 respectively, so as to facilitate the rapid discharge of hot air from the first heat dissipation channel 140 and the second heat dissipation channel 150.

[0056] In optional embodiments, such as Figure 6 As shown, the bottom of the cabinet 100 can be provided with a first air inlet 180. The internal space 110 and the air inlet channel 120 can be connected through the first air inlet 180. The first fan assembly 1900 can include a first air inlet fan 1910. The first air inlet fan 1910 can be set at the first air inlet 180. With this setting, the airflow generated by the first air inlet fan 1910 can directly act on the internal space 110, which can significantly improve the cooling efficiency of the internal space 110 and is more conducive to achieving rapid cooling of the internal space 110.

[0057] Optionally, the bottom of the cabinet 100 may be provided with at least two first air inlets 180, and the first fan assembly 1900 may include at least two first air inlet fans 1910, with each first air inlet fan 1910 being respectively and correspondingly disposed at each of the first air inlets 180. In this way, rapid cooling of the internal space 110 can be further achieved.

[0058] In some embodiments, such as Figure 6 As shown, a second air inlet 190 can also be provided at the bottom of the cabinet 100. The second air inlet 190 can be located below the air inlet channel 120 and connected to the air inlet channel 120. Cold air outside the cabinet 100 can enter the air inlet channel 120 through the second air inlet 190.

[0059] Optionally, the first fan assembly 1900 may also include a second intake fan 1920, which may be located at the second air inlet 190. This arrangement facilitates the entry of cold air from the outside into the air inlet channel 120 more easily and quickly.

[0060] In this embodiment, the bottom of the cabinet 100 may be provided with at least two second air inlets 190, each of which can communicate with the air inlet channel 120. Furthermore, the first fan assembly 1900 may include at least two second air inlet fans 1920, each of which can be respectively and correspondingly positioned at each of the second air inlets 190. This arrangement helps to increase the air intake volume.

[0061] Optionally, at least a portion of the second air inlet 190 may be opposite to the first air inlet 180 to allow cold air to enter the interior space 110. At least a portion of the second air inlet 190 may be opposite to the first heat dissipation channel 140 and the second heat dissipation channel 150 respectively to allow cold air to enter the first heat dissipation channel 140 and the second heat dissipation channel 150.

[0062] To prevent external dust, particles, and other impurities from entering the cabinet 100, a filter can be installed at the second air inlet 190.

[0063] Optionally, when a large amount of dust or other debris accumulates on the filter screen, the control module can control the first intake fan 1910 and the second intake fan 1920 to reverse their positions, so as to back-blow the filter screen, causing the dust or other debris on the filter screen to fall off, thereby achieving the effect of cleaning the filter screen.

[0064] It should be noted that the operator can input a filter cleaning signal to the control module, causing the control module to reverse the first intake fan 1910 and the second intake fan 1920. Alternatively, the data center mobile emergency rack cabinet can also include a time module with a preset duration. When the first intake fan 1910 and the second intake fan 1920 have rotated forward for the preset duration, the control module will control the first intake fan 1910 and the second intake fan 1920 to rotate in reverse. When the first intake fan 1910 and the second intake fan 1920 are rotating forward, it indicates that the first intake fan 1910 and the second intake fan 1920 are in normal working condition, allowing cool air to enter the internal space 110 and the air intake channel 120.

[0065] Optionally, the mobile emergency rack cabinet for the data center may further include a wind pressure detection element. This element can detect the pressure at the second air inlet 190. For example, the wind pressure detection element can be installed inside the fan cabinet of the second air inlet fan 1920. When the second air inlet fan 1920 is in normal operating condition (i.e., rotating forward), and the wind pressure detection element detects that the pressure at the second air inlet 190 is less than a preset pressure, it indicates that the dust and other debris accumulated on the filter screen at the second air inlet 190 are significant, leading to increased air resistance. In this case, the control module controls the first air inlet fan 1910 and the second air inlet fan 1920 to reverse direction, thereby automatically cleaning the filter screen. Here, the wind pressure detection element can be a wind pressure sensor.

[0066] In some embodiments, the cross-sectional areas of the air inlet channel 120 and the air outlet channel 130 in the horizontal direction are both larger than those of the first heat dissipation channel 140 and the second heat dissipation channel 150 in the horizontal direction. Thus, when airflow flows from the air inlet channel 120 into the relatively smaller first heat dissipation channel 140 or the second heat dissipation channel 150, the airflow velocity increases due to the narrowing of the space. Subsequently, the airflow flows from the first heat dissipation channel 140 or the second heat dissipation channel 150 into the larger air outlet channel 130, causing the space to expand. This process of first contracting and then expanding the airflow space creates a structure similar to the Venturi effect, effectively accelerating the airflow velocity and facilitating rapid cooling of the first heat dissipation channel 140 and the second heat dissipation channel 150.

[0067] Optionally, the cross-sectional areas of both the air inlet channel 120 and the air outlet channel 130 in the horizontal direction are larger than the cross-sectional area of ​​the internal space 110 in the horizontal direction. Thus, when airflow flows from the air inlet channel 120 into the relatively smaller internal space 110, the airflow velocity increases due to the narrowing of the space. Subsequently, the airflow flows from the internal space 110 into the larger air outlet channel 130, causing the space to expand. This process of airflow first contracting and then expanding creates a structure similar to the Venturi effect, effectively accelerating the airflow velocity and facilitating rapid cooling of the internal space 110.

[0068] In this embodiment, if the insulation monitoring module 1000 detects a risk of leakage, the control module controls the first fan assembly 1900 and the second fan assembly 2000 to stop working.

[0069] Furthermore, when the cabinet door of the cabinet 100 is open, the control module stops the first fan assembly 1900 and the second fan assembly 2000 to prevent external dust and other contaminants from entering the cabinet 100. When the cabinet door of the cabinet 100 is closed, the first fan assembly 1900 and the second fan assembly 2000 can resume normal operation.

[0070] Optionally, a lighting device may also be installed inside the cabinet 100. The lighting device can be connected to the control module. When the cabinet door of the cabinet 100 is open, the control module can control the lighting device to illuminate. When the cabinet door of the cabinet 100 is closed, the control module can control the lighting device to turn off.

[0071] In optional embodiments, such as Figure 1As shown, a grounding interface 500 can be installed on the cabinet 100, which can be used to connect to the grounding wire. This configuration can conduct static electricity generated on the surface of the cabinet 100 and leakage current from internal components to the ground, preventing the accumulation of static electricity or leakage current. This protects internal components from static damage and effectively reduces the risk of electric shock to operators, ensuring their safety. At the same time, grounding the cabinet 100 can also conduct electromagnetic interference generated by the internal components of the cabinet 100 to the ground, reducing the impact of electromagnetic fields on the mobile emergency rack cabinet of the data center, thereby improving the anti-interference capability of the mobile emergency rack cabinet of the data center.

[0072] In other embodiments, the grounding interface 500 may not be provided on the cabinet 100.

[0073] In an optional embodiment, the data center mobile emergency rack cabinet may further include a second temperature detection element, at least two third temperature detection elements, and an alarm module. The second temperature detection element may be positioned close to the input connector 300 and can be used to detect the temperature of the input connector 300; each of the third temperature detection elements may be positioned close to each output connector 400 and can be used to detect the temperature of the corresponding output connector 400; the alarm module may be communicatively connected to the second and third temperature detection elements, and the alarm module may be used to issue an alarm when the second temperature detection element detects that the temperature of the input connector 300 is greater than or equal to a sixth preset temperature, and / or when the third temperature detection element detects that the temperature of the corresponding output connector 400 is greater than or equal to a seventh preset temperature. In this embodiment, the second and third temperature detection elements can monitor the temperatures of the input connector 300 and the output connector 400 respectively. When the temperature exceeds a safety threshold, the alarm module issues an alarm, which can remind operators to take timely measures to avoid damage to the input connector 300 or the output connector 400 due to excessive temperature, thereby ensuring the stable operation of the data center mobile emergency rack cabinet and the load 1700 connected to the data center mobile emergency rack cabinet. Furthermore, each output connector 400 is equipped with an independent third temperature sensing element. When the temperature of a certain output connector 400 is abnormal, the alarm module can clearly indicate which output connector 400 is causing the problem. This helps operators quickly and accurately locate the fault, improving troubleshooting efficiency and shortening maintenance time. Here, both the sixth and seventh preset temperatures can be set to 50℃. For example, both the second and third temperature sensing elements can be temperature sensors.

[0074] In other embodiments, the mobile emergency rack cabinet for data centers may also exclude the second temperature detection element, at least two third temperature detection elements, and alarm module.

[0075] In an optional embodiment, the cabinet 100 is equipped with a main control switch 600 and at least two sub-control switches 700. The main control switch 600 is electrically connected to the input connector 300, and each sub-control switch 700 corresponds one-to-one with each output connector 400. Each output connector 400 is electrically connected to the main control switch 600 through its corresponding sub-control switch 700. This configuration allows the main control switch 600 to control the power input of the entire data center mobile emergency rack cabinet. By operating the main control switch 600, the power supply to all output connectors 400 can be switched on or off at once, facilitating rapid power disconnection during comprehensive system overhaul, maintenance, or emergency shutdown. Each sub-control switch 700 is connected to its corresponding output connector 400, allowing operators to individually control the power supply to each output connector 400 without affecting the normal operation of other output connectors 400. For example, when a load 1700 connected to an output connector 400 malfunctions and needs maintenance, the corresponding sub-control switch 700 can be turned off to safely operate the load 1700 without interrupting the operation of other loads 1700, thus ensuring business continuity.

[0076] In other embodiments, the cabinet 100 may also contain only a main control switch 600 or at least two sub-control switches 700.

[0077] In this embodiment, both the main control switch 600 and the branch control switch 700 may include circuit breakers. For example, the main control switch 600 may include a 1200A DC circuit breaker 610, such as... Figure 5 As shown, the DC circuit breaker 610 may be equipped with a shunt trip unit 620, so that in the event of a fire, a fire alarm signal can be input to the shunt trip unit 620, and the DC circuit breaker 610 can be remotely controlled through the shunt trip unit 620 to open the DC circuit breaker 610 and disconnect the circuit. The control switch 700 may include a 63A DC miniature circuit breaker.

[0078] In an optional embodiment, a grounding device may also be installed inside the cabinet 100. The main control switch 600 and each of the sub-control switches 700 can be electrically connected to the grounding device, which can be used for grounding. With this configuration, when the circuit of the entire cabinet 100 experiences a fault, short circuit, or overload, the input connector 300 and output connector 400 can be grounded through the grounding of the main control switch 600 and each of the sub-control switches 700, thus conducting the current of the input connector 300 and output connector 400 to the ground, thereby avoiding the risk of electric shock in the event of an electrical fault.

[0079] For example, the grounding element can be installed at the bottom of the cabinet 100, and the area of ​​the grounding element can be less than or equal to 50 mm².2 The grounding component can be a grounding copper busbar.

[0080] Of course, grounding components may not be installed inside the cabinet.

[0081] Optionally, the main control switch 600 and each of the sub-control switches 700 can be electrically connected to a grounding component via grounding wires, and each grounding wire is provided with a grounding pin at its end, allowing each grounding wire to be electrically connected to the grounding component via the grounding pin. This facilitates connection and disconnection.

[0082] In an optional embodiment, the main control switch 600 can be electrically connected to each of the sub-control switches 700 via a busbar. With this configuration, the main control switch 600 and each control switch are connected to the busbar respectively, which can effectively shorten the length of the wires and make the wiring in the cabinet 100 simpler and clearer. This allows for more space to be left for the installation and wiring of other electrical components, making the layout of the entire electrical system more reasonable and compact.

[0083] Of course, the main control switch 600 can also be electrically connected to each sub-control switch 700 without a busbar. The main control switch 600 can be electrically connected to each sub-control switch 700 respectively through wires.

[0084] Optionally, the cabinet 100 may be equipped with a cabinet door, and the busbar may be located inside the cabinet door. The data center mobile emergency rack cabinet may also include an opening / closing detection device, which can be used to detect the opening / closing status of the cabinet door. The opening / closing detection device can be communicatively connected to the main control switch 600, which can be used to open the cabinet door when the opening / closing detection device detects that the cabinet door is open. This configuration allows the main control switch 600 to be linked to the cabinet door. When the cabinet door is opened for inspection or maintenance of the internal components of the cabinet 100, the main control switch 600 opens, automatically de-energizing the busbar and related circuits, thus enabling power-off operation and ensuring the safety of the operators.

[0085] For example, the opening / closing detection component can be an angle sensor, which can be used to detect the angle of rotation of the cabinet door in order to determine the opening / closing state of the cabinet door based on the angle of the cabinet door.

[0086] In other embodiments, the data center mobile emergency rack may also not include an opening / closing detection device.

[0087] Optionally, the main control switch 600 and each of the branch control switches 700 can be located inside the cabinet door. Furthermore, the main control switch 600, busbar, and branch control switches 700 are spaced apart from top to bottom to facilitate connection. To reduce the space occupied by the wires, at least two wire troughs are provided on the cabinet door. Each wire trough can be vertically aligned and can hold at least one wire.

[0088] In some embodiments, the cabinet 100 may be provided with 20 output connectors 400, each output connector 400 being connected to a busbar via a wire, and the cabinet door may be provided with two wire grooves, each wire groove being able to fix 10 wires.

[0089] Of course, the number of output connectors 400 can be less than 20 or more than 20, depending on actual needs.

[0090] Optionally, the cabinet 100 may also be equipped with at least two indicator lights, each corresponding to one of the output connectors 400. When the output connector 400 is electrically connected to the load 1700, the corresponding indicator light will illuminate so that the operator can observe the connection status between the output connector 400 and the load 1700.

[0091] In some embodiments, the branch control switch 700 may include a trip unit, which can be communicatively connected to a corresponding third temperature sensing element. When the third temperature sensing element detects that the temperature of the corresponding output connector 400 is greater than or equal to an eighth preset temperature, the trip unit can control the DC miniature circuit breaker of the branch control switch 700 to open, thereby de-energizing each output connector 400. Here, the eighth preset temperature is greater than a fourth preset temperature. For example, the fourth preset temperature may be 25°C, and the eighth preset temperature may be 50°C.

[0092] Furthermore, when an overload is detected in the branch control switch 700, the trip unit controls the DC miniature circuit breaker of the branch control switch 700 to open, thereby de-energizing the corresponding output connector 400.

[0093] When a short circuit occurs in the output connector 400, the trip unit controls the DC miniature circuit breaker of the branch control switch 700 to open, thereby de-energizing the corresponding output connector 400.

[0094] In an optional embodiment, the mobile emergency data center cabinet may further include a surge protection module 800. The surge protection module 800 can be installed inside the cabinet 100, connected in parallel with each output connector 400, and electrically connected to the input connector 300. In this embodiment, because the surge protection module 800 is electrically connected to the input connector 300, it can quickly conduct the overvoltage to the ground when a lightning overvoltage occurs, dissipating the overvoltage energy and keeping the voltage of the output connector 400 within a safe range, thereby protecting the subsequently connected loads 1700 and other equipment from lightning damage. Furthermore, while dissipating overvoltage, the surge protection module 800 can also limit the passage of overcurrent, protecting the electrical components and wiring inside the mobile emergency data center cabinet from overcurrent damage, ensuring the safe and stable operation of the mobile emergency data center cabinet.

[0095] Of course, the mobile emergency rack cabinet for data centers may also not include the lightning protection module 800.

[0096] In some embodiments, the surge protection module 800 can be a DC surge protector. The surge protection module 800 can be applied to systems with DC voltage below 1500V. Its nominal discharge current (In) is 20kA (8 / 20μs waveform), and the maximum discharge current can reach 40kA. It can effectively discharge surge energy generated by lightning induction or switching operation.

[0097] In an optional embodiment, the mobile emergency rack cabinet for the data center may further include at least two insulation monitoring modules 1000 and an alarm module. Each insulation monitoring module 1000 may correspond one-to-one with each output connector 400. The insulation monitoring module 1000 may be used to detect whether the corresponding output connector 400 is leaking current. The alarm module may be communicatively connected to each insulation monitoring module 1000. The alarm module may be used to sound an alarm when the insulation monitoring module 1000 detects leakage current in the output connector 400.

[0098] In this embodiment, each insulation monitoring module 1000 corresponds to one output connector 400, enabling real-time and accurate detection of the insulation status of the output connector 400 to promptly identify potential leakage hazards. When the insulation monitoring module 1000 detects leakage in the output connector 400, the alarm module can sound an alarm so that operators can be notified promptly and take swift measures to prevent damage to the data center's mobile emergency rack cabinet.

[0099] Of course, the mobile emergency rack cabinet for data centers may also exclude the insulation monitoring module 1000.

[0100] For example, the insulation monitoring module 1000 can be an insulation monitor with a monitoring voltage range of 0-1500V. Alternatively, the insulation monitoring module 1000 can be an insulation transformer.

[0101] Optionally, the output connector 400 may include a positive terminal 410 and a negative terminal 420. The positive terminal of the insulation monitoring module 1000 may be electrically connected to the positive terminal 410, and the negative terminal of the insulation monitoring module 1000 may be electrically connected to the negative terminal 420, so as to perform leakage current monitoring on the output connector 400 and indirectly reflect the insulation status of the output connector 400.

[0102] In an optional embodiment, the mobile emergency data center cabinet may further include a push-pull handle, which may be rotatably or retractably connected to the cabinet 100. In this embodiment, the push-pull handle provides a leverage point for the operator, facilitating the movement of the mobile emergency data center cabinet. Furthermore, since the push-pull handle is rotatably or retractably connected to the cabinet 100, it can be folded or retracted when the mobile emergency data center cabinet is not needed, reducing the space occupied by the handle and thus reducing the overall space occupied by the mobile emergency data center cabinet.

[0103] In other embodiments, the data center movable emergency rack may also not include push-pull handles.

[0104] In an optional embodiment, the data center mobile emergency rack cabinet may further include a first cable and a second cable 1800. The first end of the first cable may be provided with a first connector, which can be detachably connected to and electrically connected to an input connector 300. The second end of the first cable can be used for electrical connection to a power source. The first end of the second cable 1800 may be provided with a second connector, which can be detachably connected to and electrically connected to an output connector 400. The second end of the second cable 1800 can be used for electrical connection to a load 1700. This configuration facilitates the connection and disconnection of the first and second cables 1800, allowing the power source and load to be connected to the data center mobile emergency rack cabinet as needed.

[0105] Of course, the first cable can also be non-detachably connected to the input connector 300, and the second cable 1800 can also be non-detachably connected to the output connector 400.

[0106] Optionally, both the first and second connectors can be aviation plugs, which facilitates insertion and removal.

[0107] The first connector and the input connector 300 may each have a first positioning protrusion and a first positioning groove. When the first connector and the input connector 300 are connected, the first positioning protrusion is embedded in the first positioning groove. This design can prevent mis-insertion.

[0108] One of the second connector and the output connector 400 is provided with a second positioning protrusion, and the other is provided with a second positioning groove. When the second connector and the output connector 400 are connected, the second positioning protrusion is embedded in the second positioning groove. This design can prevent mis-insertion, so as to avoid the positive and negative terminals of the second connector being reversed with the positive terminal 410 and the negative terminal 420 of the output connector 400.

[0109] In other embodiments, the first positioning protrusion and the first positioning groove may not be provided on the first connector and the input connector 300, and the second positioning protrusion and the second positioning groove may not be provided on the second connector and the output connector 400.

[0110] In an optional embodiment, the mobile emergency data center cabinet may further include a first current detection module 900 and a second current detection module 1100. The first current detection module 900 can be used to detect the current at the input connector 300, and the second current detection module 1100 can be used to detect the current at the output connector 400. For example, the first current detection module 900 can be a DC meter, which can be electrically connected to the input connector 300 to monitor the current in the main circuit. The second current detection module 1100 can be a power monitor. The mobile emergency data center cabinet may include at least two second current detection modules 1100, each of which can be electrically connected to each output connector 400 in a one-to-one correspondence to monitor the power of each output connector 400. Here, the power monitor can be a current transformer. The current transformer can be a 63A / 75mV DC shunt.

[0111] Optionally, one of the first connector and the input connector 300 may be provided with a first limiting rod and a first driving member for driving the extension and retraction of the first limiting rod, while the other may be provided with a first slot. The first driving member can be communicatively connected to the first current detection module 900. When the first current detection module 900 detects current, the first driving member drives the first limiting rod to extend into the first slot. With this configuration, when the first current detection module 900 detects that the current flowing through the input connector 300 is greater than zero, i.e., there is current flowing between the first connector and the input connector 300, it indicates that they are normally connected and in a powered-on state. At this time, the first driving member drives the first limiting rod to extend into the first slot, tightly locking the first connector and the input connector 300, ensuring the reliability of the connection between the first connector and the input connector 300, and preventing equipment failure due to the first connector falling off. Here, the first driving member can be an electric push rod.

[0112] Of course, the first limit rod and the first slot may not be provided on either the first connector or the input connector 300.

[0113] One of the second connector and the output connector 400 may be provided with a second limiting rod and a second driving member for driving the extension and retraction of the second limiting rod, while the other may be provided with a second slot. The second driving member can be communicatively connected to the second current detection module 1100. When the second current detection module 1100 detects current, the second driving member drives the second limiting rod to extend into the second slot. With this configuration, when the second current detection module 1100 detects that the current flowing through the output connector 400 is greater than zero, i.e., there is current flowing between the second connector and the output connector 400, it indicates that they are normally connected and in a powered-on state. At this time, the second driving member drives the second limiting rod to extend into the second slot, tightly locking the second connector and the output connector 400, ensuring the reliability of the connection between the second connector and the output connector 400 and preventing equipment failure due to the second connector falling off. Here, the second driving member can be an electric push rod.

[0114] Of course, the second limit rod and the second slot may not be provided on the second connector and the output connector 400.

[0115] In an optional embodiment, a display screen 1200 may be provided on the cabinet 100. The display screen 1200 can be communicatively connected to the alarm module, insulation monitoring module 1000, first temperature detection element, second temperature detection element and third temperature detection element mentioned above, so as to display alarm information, insulation monitoring information, temperature inside the cabinet 100, temperature of input connector 300 and temperature of each output connector 400, so as to facilitate observation by the operator.

[0116] Optionally, the cabinet 100 may also include a monitoring host 1300, an insulation signal receiving module 1400, a branch circuit power detection module 1500, and a branch circuit switch quantity detection module 1600. The insulation signal receiving module 1400 can be electrically connected to each insulation monitoring module to receive signals from each module, process the signals, and transmit them to the monitoring host 1300, which then transmits the signals to the display screen 1200 for display. The branch circuit power detection module 1500 can be electrically connected to each second current detection module 1100 to receive signals from each module, process the signals, and transmit them to the monitoring host 1300, which then transmits the signals to the display screen 1200 for display. The branch circuit switch quantity detection module 1600 can be electrically connected to each sub-control switch 700 to detect the opening and closing of each sub-control switch 700 and transmit the detected signal to the monitoring host 1300, so that the monitoring host 1300 transmits the signal to the display screen 1200 for display. Here, each insulation monitoring module can be electrically connected to the insulation signal receiving module 1400 via RS485 cable, and the insulation signal receiving module 1400 can be electrically connected to the monitoring host 1300 via RS485 cable. Each second current detection module 1100 can be electrically connected to the branch circuit power detection module 1500 via RS485 cable, and the branch circuit power detection module 1500 can be electrically connected to the monitoring host 1300 via RS485 cable. Each sub-control switch 700 can be electrically connected to the branch circuit switch quantity detection module 1600, and the branch circuit switch quantity detection module 1600 can be electrically connected to the monitoring host 1300 via RS485 cable. The monitoring host 1300 can be electrically connected to the display screen 1200 via RS485 cable. The display screen 1200 can be a touch screen, specifically an HMI touch screen. The RS485 cable can communicate with the monitoring host 1300 via the Modbus communication protocol.

[0117] In addition, the display screen 1200 can display the input voltage, input current, input power and input charge of the input connector 300.

[0118] For example, the monitoring host 1300 may include the control module described above.

[0119] Optionally, the cabinet 100 may be equipped with a remote monitoring interface, which can be electrically connected to the monitoring host 1300, and can also be used to electrically connect to a computer or other devices via cable. The remote monitoring interface and the monitoring host 1300 can communicate via the Modbus communication protocol.

[0120] In some embodiments, the output connector 400 may be electrically connected to a power distribution unit (PDU), which may be electrically connected to multiple loads 1700, so that multiple loads 1700 can be powered simultaneously through one output connector 400.

[0121] In some embodiments, a storage compartment may be provided on the cabinet 100. The storage compartment may be located at the bottom of the cabinet 100 and may be used to store items such as cables.

[0122] In this application embodiment, the mobile emergency power distribution unit for data centers meets the GB / T 18487.1-2015 DC insulation standard and is applicable to emergency power supply scenarios such as data centers, 5G base stations, and energy storage power stations. Specifically, the mobile emergency power distribution unit for data centers in this application is suitable for outdoor scenarios such as 5G base stations and energy storage power stations. Due to its mobility, lightning protection grounding, and IP54 or higher protection design, it can also be used for emergency power supply in outdoor or semi-outdoor environments such as 5G base stations, energy storage power stations, and edge data centers. Furthermore, during the data center expansion and renovation, and new rack testing phases, the mobile emergency power distribution unit for data centers in this application can serve as a temporary power distribution unit, providing 20 63A outputs and supporting batch load access to avoid affecting the operation of existing systems. The mobile emergency power distribution unit for data centers in this application can be used in data center disaster recovery (DR) drills or actual disaster scenarios as a rapidly deployable backup power distribution device, supporting disaster recovery switching between different locations or within the same city. The mobile emergency rack cabinet of this application can be deployed and connected to the rack within 10–15 minutes, which is much faster than the replacement of traditional fixed rack cabinets (which usually takes more than 2 hours), greatly shortening the time to repair (MTTR) and improving system availability.

[0123] The input connectors 300 and output connectors 400 of the mobile emergency data center cabinet adopt an aviation plug design, supporting hot-swapping and eliminating the need for power outage wiring, thus avoiding human error risks. This is particularly suitable for data center environments where prolonged power outages are not permissible. Furthermore, the mobile emergency data center cabinet integrates an integrated HMI touchscreen and a monitoring host 1300, enabling real-time monitoring of the voltage, current, power, charge, and insulation status of the input connectors 300 and 20 output connectors 400. It supports remote alarms and energy efficiency analysis. It also features multiple safety designs including insulation monitoring, lightning protection, cabinet door interlocking, and temperature-controlled air cooling, complying with national standard GB / T 18487.1-2015 to ensure safe operation in emergency situations. It also allows for multi-purpose use, serving multiple computer rooms or sites in rotation, reducing the number of backup mobile emergency data center cabinets and saving investment and storage costs; while also avoiding business losses and reputational risks caused by power outages.

[0124] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
