Description

Technical Field

[0001] This application relates to the field of integrated equipment technology, and in particular to integrated in-line fire cabinets and data centers. Background Technology

[0002] With the development of cloud computing, big data, and artificial intelligence, data centers are expanding in scale, and the integration and power density of equipment are rapidly increasing. As the core infrastructure for information and digitalization, data centers place extremely high demands on security, reliability, and business continuity. Among these, fire hazards have become one of the key risks affecting the stable operation of data centers. Therefore, the fire suppression systems used in modular data centers are particularly important, as they can achieve the goals of rapid fire suppression and minimal damage.

[0003] Currently, data center fire suppression systems primarily employ the following methods: First, utilizing existing building fire suppression mechanisms, such as sprinkler systems and fire-fighting gas systems. However, due to the high water sensitivity of data center equipment, sprinkler systems are rarely used. Fire-fighting gas systems, on the other hand, generate significant amounts of dust after the extinguishing agent is sprayed, which can corrode and contaminate precision equipment, thus also being less common. Second, data center computer rooms are equipped with dedicated fire suppression systems, such as fire detection tube systems. These systems deploy fire detection tubes in the data center computer room or areas where fires may occur, enabling system-wide fire suppression. However, they are suitable for small spaces, have a limited range of fire suppression, and may malfunction in high-temperature environments, while low-temperature environments may affect response speed. Utility Model Content

[0004] This application provides an integrated in-line fire cabinet and data center, which is designed to provide an integrated, highly integrated, and highly intelligent fire cabinet to achieve early detection and rapid response to fires, and to ensure the safe operation of the data center.

[0005] In a first aspect, embodiments of this application provide an integrated in-line fire cabinet, comprising: a cabinet, a U-shaped mounting partition, a fire cylinder, an early fire detection device, a fire controller, a battery, an alarm indicator light, a stop button, a release switch, an exhaust fan, and an uninterruptible power supply. The U-shaped mounting partition is vertically installed inside the cabinet, dividing the interior of the cabinet into multiple enclosed spaces along the front-to-back direction. The fire-fighting gas cylinder is fixed inside the U-shaped mounting partition by mounting brackets. The very early fire detection device, the fire controller, the battery, and the exhaust fan are all installed on the side of the U-shaped mounting partition near the cabinet door. The alarm indicator light, the stop button, and the release switch are installed on the cabinet door. The battery powers the fire controller, and the uninterruptible power supply powers the fire controller and the exhaust fan. The fire controller controls the fire-fighting gas cylinder through a valve switch.

[0006] The aforementioned fire cabinet integrates fire-fighting gas cylinders, an early-stage fire detection device, a fire controller, batteries, alarm indicator lights, stop buttons, release switches, exhaust fans, and uninterruptible power supplies. This integrated design boasts a high degree of integration and intelligence, enabling independent operation or integration with data center solutions. It allows for rapid deployment, saving on-site engineering work, and is easy to maintain, allowing for single-cabinet maintenance. Furthermore, the fire cabinet integrates intelligent monitoring functions such as environmental monitoring, alarm reporting, emergency shutdown, alarm activation, and manual operation. It also employs an early-stage fire detection device for early fire detection and rapid response, thereby truly ensuring the operational safety of the data center.

[0007] The fire cabinet provided in this application embodiment is divided into front and rear hot and cold aisles by a U-shaped mounting partition, which is consistent with the hot and cold aisles of the modular data center. This prevents the hot and cold aisles of the data center from mixing during normal use, which would affect the cooling efficiency. In addition, a ventilation fan is installed on the U-shaped mounting partition. When the fire controller controls the release of fire gas cylinders, the ventilation fan can be turned on through the pre-release alarm signal and relay linkage control, so that the fire gas can be evenly distributed in the hot and cold aisles and can quickly fill the protected area, reduce the oxygen concentration in the protected area, and improve the fire extinguishing effect.

[0008] In one possible implementation, the fire cabinet further includes: a sensor assembly connected to at least one alarm signal dry contact of the fire controller, the sensor assembly receiving alarm signals reported by the fire controller and reporting the alarm signals to the monitoring host.

[0009] The aforementioned fire cabinet's sensor components are connected to at least one alarm signal dry contact on the fire controller. The sensor components promptly report alarm signals from the fire controller to the monitoring host, enabling the fire protection system to report alarms in real time. This allows for centralized display, recording, and analysis of alarms. The status of the fire protection system can also be directly obtained from the data center system's monitoring host. Furthermore, the monitoring host can trigger fire-fighting linkages based on the alarm signal type or alarm level reported by the fire controller. For example, in the event of a fire, if the data center temperature is high and the ventilation fans in the fire cabinet are already activated, an alarm signal can be emitted to trigger the shutdown of emergency fans in all cabinets within the data center, preventing outside air from entering the data center modules and causing further fire spread.

[0010] In one possible implementation, the fire cabinet further includes at least one release nozzle connected to a pre-arranged discharge pipe connected to the fire cylinder.

[0011] In the aforementioned fire cabinet, both the fire-fighting gas cylinder and the release nozzle are integrated into the fire-fighting cabinet. The release nozzle is connected to a pre-arranged discharge pipe. Specifically, multiple release nozzles can be installed and arranged in the front and rear hot and cold aisles of the data center, so that the fire-fighting gas can be released into the hot and cold aisles of the data center simultaneously.

[0012] In one possible implementation, the fire cabinet further includes a pressure release switch disposed in the discharge pipe. The pressure release switch is used to sense the pressure in the discharge pipe, determine the release status of the fire cylinder, and send the release status of the fire cylinder to the fire controller.

[0013] In the aforementioned fire cabinet, a pressure release switch is installed in the discharge pipe. When the fire extinguishing system is activated and releases gas, the pressure inside the pipe rises. After sensing this change, the pressure release switch triggers its internal electrical contacts, and sends a signal to the fire controller or alarm system to confirm that the extinguishing agent has been successfully released. This signal can also be used to activate subsequent linkages, such as shutting down the ventilation system or triggering audible and visual alarms.

[0014] In one possible implementation, the very early fire detection device includes a detector and at least one sampling channel installed within the data center module. The detector collects air samples inside the data center module through the sampling channel for laser detection. If a fire warning is triggered, the detector sends an abnormal signal to the fire controller, which then triggers the alarm indicator light.

[0015] The aforementioned fire cabinet is equipped with an early fire detection device, which is a highly sensitive air sampling smoke detection system. By arranging sampling pipes within the data center module, air samples are continuously drawn into the detector. The system uses a highly sensitive laser to detect minute amounts of smoke particles in the air. Based on changes in smoke concentration, the system interprets and triggers an alarm, providing a tiered response. The triggered alarm can be linked to audible and visual alarm lights, fire controllers, etc., while simultaneously recording events for centralized management.

[0016] In the aforementioned fire cabinet, after the very early fire detection device reports an abnormal signal, the fire controller receives the signal from the very early fire detector, determines whether there is a fire risk in the system, detects an abnormality and triggers the audible and visual alarm device to remind personnel to respond in time, and at the same time issues an alarm signal. Based on the actual fire detection data, it can trigger the valve switch on the fire gas cylinder to release the fire gas. At the same time, the fire controller is equipped with a battery to prevent the fire protection system from failing due to a power outage caused by the burning of the power supply line during a fire.

[0017] In one possible implementation, the fire controller includes: a relay, which, upon receiving a pre-eruption alarm signal triggered by the fire controller (14) at the control terminal, closes the emergency stop port of the data center power distribution cabinet connected to the load terminal of the relay, or closes the emergency stop port of the cooling unit and uninterruptible power supply in the data center connected to the load terminal of the relay.

[0018] The fire control unit in the aforementioned fire cabinet includes a relay, which enables the fire cabinet to have an linkage function. In the event of a fire, this linkage function will cause the cooling unit and uninterruptible power supply unit in the data center to shut down immediately, preventing the air conditioner from continuing to run and causing the temperature of the fire source to rise, thus intensifying the fire. At the same time, it will prevent damage to the uninterruptible power supply system caused by high temperature or the release of extinguishing agents, thereby protecting the equipment. In addition, before shutting down, the system linkage can trigger server data backup or transfer to reduce the risk of data loss, so as to maximize the protection of personnel safety, equipment safety and data integrity.

[0019] In one possible implementation, the uninterruptible power supply is connected to a distribution cabinet, and the uninterruptible power supply includes a battery assembly.

[0020] In the aforementioned fire cabinet, the ventilation fan is powered by an uninterruptible power supply (UPS). The UPS is connected to the distribution cabinet and contains batteries. If the UPS power supply line burns out during a fire, the UPS can continue to power the ventilation fan through the batteries, allowing it to work normally.

[0021] In one possible implementation, the fire-fighting gas in the fire-fighting cylinder is an inert fire-fighting gas.

[0022] In the aforementioned fire cabinet, the fire-fighting gas cylinders use inert fire-fighting gas. In the event of a fire, the fire-fighting gas is quickly released into the protected area, diluting the oxygen concentration in the air so that the fire cannot sustain combustion. It does not chemically react with the flame, does not produce any byproducts or corrosive substances, ensures equipment safety, and is environmentally friendly, pollution-free, non-toxic, and residue-free.

[0023] In one possible implementation, the fire cabinet further includes a cabinet assembly, and the side panels of the fire cabinet are removable.

[0024] Secondly, embodiments of this application provide a data center, which includes: at least one integrated in-line fire cabinet as provided in the first aspect of embodiments of this application and at least one server cabinet, wherein the fire cabinet and the server cabinet are connected in parallel.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In the description of the embodiments of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0029] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] Before introducing the integrated fire cabinet and data center provided in the embodiments of this application, the technical background of the embodiments of this application will be described in detail for ease of understanding.

[0031] With the development of cloud computing, big data, and artificial intelligence, data centers are expanding in scale, and the integration and power density of equipment are rapidly increasing. As the core infrastructure for information and digitalization, data centers place extremely high demands on security, reliability, and business continuity. Among these, fire hazards have become one of the key risks affecting the stable operation of data centers. Therefore, the fire suppression systems used in modular data centers are particularly important, as they can achieve the goals of rapid fire suppression and minimal damage.

[0032] Currently, data center fire suppression systems mainly employ the following methods: First, utilizing existing building fire suppression methods, such as sprinkler systems and fire-fighting gas systems. However, due to the high water sensitivity of data center equipment, sprinkler systems are rarely used, and fire-fighting gas systems, which generate large amounts of dust after spraying, easily corrode and contaminate precision equipment, are also rarely used. Second, data center computer rooms are equipped with separate fire suppression systems, such as fire detection tube systems. These systems deploy fire detection tubes in the data center computer room or areas where fires may occur, enabling system-wide fire suppression. However, they are suitable for small spaces, have a limited extinguishing range, may malfunction in high-temperature environments, and may affect response speed in low-temperature environments. They lack remote monitoring and linkage capabilities, and generally use extinguishing agents such as heptafluoropropane and carbon dioxide. Heptafluoropropane primarily extinguishes fires through heat absorption and cooling combined with interrupting the combustion chain; its application is mature, but its high greenhouse effect is gradually being restricted. High concentrations of carbon dioxide are fatal to humans and are unsuitable for manned data centers.

[0033] Currently, some data centers also have standalone heptafluoropropane fire suppression systems. However, these systems require on-site installation of components such as fire cylinders, pipelines, nozzles, smoke and temperature sensors, and controllers, resulting in low integration and a large workload for overall equipment installation and maintenance, leading to higher costs. Other data centers use cabinet-type fire suppression systems, which integrate fire cylinders, pipelines, and nozzles into a single cabinet for localized protection. However, other components of the fire suppression system must be either independently installed or integrated with the data center's fire suppression system. For example, smoke and temperature sensors are independently installed in the room or fire-prone areas, fire suppression controllers are independently installed in the data center, and audible and visual alarms and emergency stop devices are also independently installed. Fire piping is installed separately, and the fire suppression cabinet only integrates components such as cylinders, pressure gauges, and solenoid valves within the cabinet. This facilitates rapid on-site deployment of these components and saves on construction time, but still requires significant on-site installation work, resulting in low system integration. Furthermore, the use of heptafluoropropane for fire suppression generally poses a greenhouse effect.

[0034] In view of this, this application provides an integrated in-line fire cabinet and data center. The fire cabinet integrates fire cylinders, early fire detection devices, fire controllers, batteries, alarm indicator lights, stop buttons, release switches, exhaust fans, and uninterruptible power supplies. The integrated design of this fire cabinet has a high degree of integration and intelligence. It can operate independently or be integrated with data center solutions for rapid deployment, saving on-site engineering work. It is also simple to maintain, as it can be maintained as a single cabinet. In addition, the fire cabinet has integrated intelligent monitoring functions such as environmental monitoring, alarm reporting, emergency shutdown, alarm, and manual operation. At the same time, it uses an early fire detection device to detect fires at the earliest stage, achieving early detection and rapid response, thereby truly ensuring the operational safety of the data center.

[0035] The fire cabinet provided in this application embodiment is divided into front and rear hot and cold aisles by a U-shaped mounting partition, which is consistent with the hot and cold aisles of the modular data center. This prevents the hot and cold aisles of the data center from mixing during normal use, which would affect the cooling efficiency. In addition, a ventilation fan is installed on the U-shaped mounting partition. When the fire controller controls the release of fire gas cylinders, the ventilation fan can be turned on through the pre-release alarm signal and relay linkage control, so that the fire gas can be evenly distributed in the hot and cold aisles and can quickly fill the protected area, reduce the oxygen concentration in the protected area, and improve the fire extinguishing effect.

[0036] It should be noted that the integrated in-line fire cabinet provided in this application embodiment can be used in combination with row-type modular data centers to provide systematic fire extinguishing functions for row-type data center products.

[0037] After introducing the background technology of the embodiments of this application, the integrated in-line fire cabinet and data center provided by the embodiments of this application will be described in detail below with reference to specific embodiments.

[0038] See Figure 1 As shown, it is a structural schematic diagram of the integrated in-line fire cabinet in the embodiment of this application, which specifically includes: cabinet 10, U-shaped mounting partition 11, fire cylinder 12, early fire detection device 13, fire controller 14, battery 15, alarm indicator light 16, stop button 17, release switch 18, exhaust fan 19, and uninterruptible power supply.

[0039] The alarm indicator 16 can be an audible and visual alarm indicator. The stop button 17 is used during the countdown or preparation phase of the fire protection system. Operators can manually or remotely trigger the stop button 17 to terminate the release of the fire extinguishing gas cylinder 12, preventing accidental discharge or gas waste when the fire is under control. This can be applied in scenarios involving false alarms, personnel not evacuated, or fires already under control. The release switch 18 is used in emergency situations. Operators can manually or remotely trigger the release switch 18 to immediately activate the fire extinguishing system without waiting for signals from the system's automatic detectors. This can be applied in scenarios where the fire has been confirmed, but the fire protection system has not activated or requires early release. This application does not limit the specific triggering methods of the stop button 17 and the release switch 18.

[0040] U-shaped mounting partition 11 is vertically installed inside the cabinet 10, dividing the interior of the cabinet 10 into multiple enclosed spaces along the front-to-back direction. Fire cylinder 12 is fixed inside the U-shaped mounting partition 11 by mounting bracket 20. Early fire detection device 13, fire controller 14, battery 15, and exhaust fan 19 are all installed on the side of the U-shaped mounting partition 11 near the cabinet door. Alarm indicator light 16, stop button 17, and release switch 18 are installed on the cabinet door. Battery 15 is used to power fire controller 14, and uninterruptible power supply is used to power fire controller 14 and exhaust fan 19. Fire controller 14 controls fire cylinder 12 through valve switch.

[0041] In practice, both the front and rear doors of rack 11 can be made of sheet metal. The side panels of rack 11 are removable for easy maintenance and expansion. A rack-sharing assembly is installed on the side panel, allowing it to be connected to other racks in the data center. The fire-fighting gas cylinder 12 is securely fixed by two layers of mounting brackets 20, and the base plate of the fire cabinet adopts a reinforced design to prevent damage to the rack during transportation of the heavy gas cylinder.

[0042] The fire cabinet provided in this application embodiment integrates a fire cylinder 12, an early fire detection device 13, a fire controller 14, a battery 15, an alarm indicator light 16, a stop button 17, a release switch 18, an exhaust fan 19, and an uninterruptible power supply. This fire cabinet features an integrated design with a high degree of integration and intelligence. It can operate independently or be integrated with data center solutions, enabling rapid deployment, saving on-site engineering work, and simple maintenance, allowing for single-cabinet maintenance. Furthermore, the fire cabinet integrates intelligent monitoring functions such as environmental monitoring, alarm reporting, emergency shutdown, alarm activation, and manual operation. Simultaneously, it employs an early fire detection device for very early fire detection, achieving early detection and rapid response, thereby truly ensuring the operational safety of the data center.

[0043] The fire cabinet provided in this application embodiment is divided into front and rear hot and cold aisles by a U-shaped mounting partition 11, which is consistent with the hot and cold aisles of the modular data center. This prevents the hot and cold aisles of the data center from mixing during normal use, which would affect the cooling efficiency. Moreover, a ventilation fan 19 is installed on the U-shaped mounting partition 11. When the fire controller controls the release of fire gas cylinders, the ventilation fan 19 can be turned on through the pre-release alarm signal and relay linkage control, so that the fire gas can be evenly distributed in the hot and cold aisles and can quickly fill the protected area, reduce the oxygen concentration in the protected area, and improve the fire extinguishing effect.

[0044] In practical applications, the integrated in-line fire cabinet provided in this application embodiment has strong flexibility, compatibility and maintainability. The cabinet design is consistent with the cabinet frame design of the data center module, and the external dimensions are basically the same. It can be combined into one cabinet. The internal hot and cold aisles are isolated, which is consistent with the closed data center module to prevent gas mixing and maintain system compatibility. The cabinet can be operated, installed and maintained independently. It is located in the last cabinet position of the data center module, which is convenient for maintenance.

[0045] In some implementations, such as Figure 2 As shown, the fire cabinet also includes: a sensor assembly 21, which is connected to at least one alarm signal dry contact of the fire controller 14. The sensor assembly 21 receives the alarm signal reported by the fire controller 14 and reports the alarm signal to the monitoring host 22.

[0046] It should be noted that the monitoring host 22 mentioned here can be the monitoring host of the data center computer room, which can control other devices in the data center computer room.

[0047] The aforementioned fire cabinet has a sensor component 21 connected to at least one alarm signal dry contact on the fire controller 14. The sensor component 21 promptly reports the alarm signals reported by the fire controller 14 to the monitoring host 22, enabling the fire system to report alarms in real time and realize centralized display, recording and analysis of alarms. The status of the fire system can also be directly obtained through the monitoring host of the data center system. Furthermore, the monitoring host can perform fire linkage based on the alarm signal type or alarm level reported by the fire controller.

[0048] For example, in the event of a fire, the temperature in the data center is high, and the ventilation fans in the fire-fighting cabinets have already started working. At this time, an alarm signal can be released to trigger the shutdown of the emergency fans 23 in all cabinets in the data center, preventing outdoor air from entering the data center modules and causing further fire spread.

[0049] In some embodiments, the fire cabinet further includes at least one release nozzle connected to a pre-arranged discharge pipe connected to a fire cylinder.

[0050] In the aforementioned fire cabinet, both the fire-fighting gas cylinder and the release nozzle are integrated into the fire-fighting cabinet. The release nozzle is connected to a pre-arranged discharge pipe. Specifically, multiple release nozzles can be installed and arranged in the front and rear hot and cold aisles of the data center, so that the fire-fighting gas can be released into the hot and cold aisles of the data center simultaneously.

[0051] In one example, such as Figure 3 As shown, two release nozzles are installed inside the fire cabinet, namely release nozzle 31 and release nozzle 32. Both release nozzle 31 and release nozzle 32 are connected to a pre-arranged discharge pipe 30. The discharge pipe 30 is connected to the fire gas cylinder. Release nozzle 31 and release nozzle 32 are respectively arranged in the front and rear hot and cold aisles of the modular data center, so that the fire gas can be discharged into the hot and cold aisles of the system at the same time.

[0052] In some embodiments, the fire cabinet further includes a pressure release switch, which is disposed in the discharge pipe and is used to sense the pressure in the discharge pipe, determine the release status of the fire cylinder, and send the release status of the fire cylinder to the fire controller.

[0053] In the aforementioned fire cabinet, a pressure release switch is installed in the discharge pipe. When the fire extinguishing system is activated and releases gas, the pressure inside the pipe rises. After sensing this change, the pressure release switch triggers its internal electrical contacts, and sends a signal to the fire controller or alarm system to confirm that the extinguishing agent has been successfully released. This signal can also be used to activate subsequent linkages, such as shutting down the ventilation system or triggering audible and visual alarms.

[0054] In some possible implementations, such as Figure 3 As shown, the very early fire detection device includes a detector and at least one sampling channel 33 installed in the data center module. The detector collects air samples inside the data center module through the sampling channel for laser detection. When it is determined that a fire warning has been triggered, it sends an abnormal signal to the fire controller and triggers an alarm indicator light.

[0055] The aforementioned fire cabinet is equipped with an early fire detection device, which is a highly sensitive air sampling smoke detection system. By arranging sampling pipes within the data center module, air samples are continuously drawn into the detector. The system uses a highly sensitive laser to detect minute amounts of smoke particles in the air. Based on changes in smoke concentration, the system interprets and triggers an alarm, providing a tiered response. The triggered alarm can be linked to audible and visual alarm lights, fire controllers, etc., while simultaneously recording events for centralized management.

[0056] In the aforementioned fire cabinet, after the very early fire detection device reports an abnormal signal, the fire controller receives the signal from the very early fire detector, determines whether there is a fire risk in the system, detects an abnormality and triggers the audible and visual alarm device to remind personnel to respond in time, and at the same time issues an alarm signal. Based on the actual fire detection data, it can trigger the valve switch on the fire gas cylinder to release the fire gas. At the same time, the fire controller is equipped with a battery to prevent the fire protection system from failing due to a power outage caused by the burning of the power supply line during a fire.

[0057] In some implementations, such as Figure 3 As shown, the fire cabinet is equipped with an uninterruptible power supply 34, which is connected to the distribution cabinet and includes a battery assembly.

[0058] In the aforementioned fire cabinet, the ventilation fan is connected to an uninterruptible power supply (UPS) 34 via a relay. When the ventilation fan needs to be started, it can be powered by the UPS 34. The UPS 34 is connected to the distribution cabinet and contains a battery. If the power supply line of the UPS burns out during a fire (the UPS 34 is disconnected from the distribution cabinet), the UPS 34 can continue to supply power to the ventilation fan through the battery, allowing it to operate normally.

[0059] In practical applications, in order to maximize the protection of personnel safety, equipment safety and data integrity, the fire cabinet provided in this application embodiment also has a linkage function. Specifically, the fire controller includes a relay, which is used to close the emergency stop port of the data center power distribution cabinet connected to the load end of the relay when the control terminal receives the pre-spray alarm signal triggered by the fire controller, or to close the emergency stop port of the cooling unit and uninterruptible power supply in the data center connected to the load end of the relay.

[0060] In practice, the specific connection method of the load side of the closed relay is determined based on whether the data center integrated power distribution cabinet module is configured with a system-level emergency stop function. Specifically: like Figure 4 As shown, if the data center integrated power distribution cabinet module does not have a system-level emergency stop function, the load end of the relay is connected to the emergency stop port of the cooling unit and the uninterruptible power supply in the data center.

[0061] In the event of a fire, the fire controller generates a pre-spray alarm signal. This pre-spray alarm signal energizes the relays inside the fire controller, directly closing the emergency stop ports of the cooling units (cooling unit 1-cooling unit n) and the uninterruptible power supplies (UPS 1-UPS n) in the data center module. This causes an emergency power outage for the cooling units and UPS in the data center module, preventing the air conditioning from continuing to run and causing the fire source temperature to rise, thus intensifying the fire. It also prevents damage to the UPS system caused by high temperatures or the release of extinguishing agents, thereby protecting the equipment. In addition, before shutdown, the system can trigger server data backup or transfer through linkage, reducing the risk of data loss.

[0062] like Figure 5 As shown, if the data center integrated power distribution cabinet module has a system-level emergency stop function, the load end of the relay is connected to the emergency stop port of the power distribution cabinet.

[0063] In the event of a fire, the fire control panel generates a pre-spray alarm signal. This signal energizes the relays inside the fire control panel, which in turn closes the emergency stop port in the power distribution cabinet of the data center. This indirectly closes the emergency stop ports of the cooling unit and the uninterruptible power supply (UPS) in the data center module, causing an emergency power outage for the cooling unit and UPS in the data center module. This prevents the air conditioning from continuing to run, which could raise the temperature of the fire source and intensify the fire. It also prevents damage to the UPS system caused by high temperatures or the release of extinguishing agents, thus protecting the equipment. In addition, before shutdown, the system can trigger server data backup or transfer, reducing the risk of data loss.

[0064] In some embodiments, the fire-fighting gas in the fire-fighting gas cylinder of the fire cabinet provided in this application is an inert fire-fighting gas.

[0065] Specifically, IG series inert fire-fighting gases can be used. In the event of a fire, the fire-fighting gas is quickly released into the protected area, diluting the oxygen concentration in the air so that the fire cannot continue to burn. It does not react chemically with the flame, does not produce any by-products or corrosive substances, ensures equipment safety, and is environmentally friendly, pollution-free, non-toxic, and residue-free.

[0066] The various parts of the fire cabinet provided in this application embodiment have been described above with reference to specific embodiments. The following section will further describe these components. Figure 6 This application provides an overview of the fire protection scheme for fire cabinets used in data centers.

[0067] like Figure 6As shown in the embodiment of this application, the fire cabinet includes the following components: a fire cylinder, an early fire detection device, a fire controller, a battery, an alarm indicator light, a stop button, a release switch, an exhaust fan, an uninterruptible power supply (including a battery), a release pressure switch, and a sensor assembly. The battery powers the fire controller, the uninterruptible power supply powers the fire controller, and the exhaust fan is powered via relay KR1. The fire controller controls the fire cylinder via a valve switch.

[0068] The very early fire detection device is a highly sensitive air sampling smoke detection system. It continuously draws air samples into the detector through sampling pipes installed within the data center module. High-sensitivity laser detection detects minute amounts of smoke particles in the air and triggers alarms based on changes in smoke concentration, providing tiered responses. Alarm triggering can synchronize with alarm indicator lights, fire control panels, etc., while simultaneously recording the event for centralized management.

[0069] The fire control panel receives signals from very early fire detection devices to determine the presence of fire risk. If an anomaly is detected, it triggers an alarm indicator light to alert personnel to take immediate action and simultaneously issues an alarm signal. Based on actual fire detection data, it can trigger valve switches (such as solenoid valves) to control fire-fighting gas cylinders, thereby releasing fire-fighting gas. The fire control panel can be powered by mains electricity (…). Figure 6 The mains power shown in Figure 2) can be supplied, or it can be supplied by an uninterruptible power supply (UPS) equipped with a battery to prevent the power supply line from burning out during a fire, which would cause the fire protection system to malfunction.

[0070] The fire suppression cabinet is pre-installed with discharge pipes and multiple release nozzles, with the nozzles positioned in the front and rear hot and cold aisles of the data center. This allows for simultaneous release of fire suppression gases into both aisles. A pressure release switch is also installed in the discharge pipes. When the fire suppression system is activated and releases gas, the pressure inside the pipes rises. This pressure release switch, sensing a change in pressure, triggers internal electrical contacts, sending a signal to the fire controller or alarm system to confirm successful release of the fire suppression gas. This signal can also be used to initiate subsequent linkages, such as shutting down the ventilation system or triggering audible and visual alarms.

[0071] To ensure even distribution and uniform concentration of the fire-fighting gas within the module, achieving optimal fire suppression, a ventilation fan is installed inside the fire cabinet. Powered by an uninterruptible power supply (UPS), the ventilation fan activates via relay KR1 when a pre-discharge alarm signal is generated by the fire controller during the release of fire-fighting gas from the cylinders. This allows the fire-fighting gas to distribute evenly in both hot and cold aisles, quickly filling the protected area, reducing oxygen concentration, and enhancing fire suppression effectiveness.

[0072] The fire-fighting gas cylinders use IG series inert fire-fighting gas. In the event of a fire, the fire-fighting gas is quickly released into the protected area, diluting the oxygen concentration in the air so that the fire cannot continue to burn. It does not chemically react with the flame, and does not produce any by-products or corrosive substances. It is very safe for equipment, environmentally friendly, non-toxic, and leaves no residue.

[0073] The fire alarm cabinet has an interlocking function, the purpose of which is to maximize the protection of personnel safety, equipment safety, and data integrity in the event of a fire. Specifically, if the data center's power distribution cabinet does not have a system-level emergency stop function, the load terminal of relay KR2 in the fire alarm controller is connected to the emergency stop port 61 of the cooling unit and the emergency stop port 62 of the uninterruptible power supply in the data center; if the data center's integrated power distribution cabinet module has a system-level emergency stop function 63, the load terminal of relay KR2 is connected to the emergency stop port 63 of the power distribution cabinet, and through the emergency stop port 63 of the power distribution cabinet, the emergency stop ports 61 and 62 of the cooling unit in the data center are controlled in an interlocking manner.

[0074] In the event of a fire, the fire controller generates a pre-spray alarm signal. This pre-spray alarm signal energizes the relays inside the fire controller, directly or indirectly through the emergency stop port 63 of the distribution cabinet, closing the emergency stop ports 61 and 62 of the cooling unit in the data center module. This causes an emergency power outage for the cooling unit and the uninterruptible power supply in the data center module, preventing the air conditioner from continuing to run and causing the fire source temperature to rise, thus intensifying the fire. It also prevents damage to the uninterruptible power supply system caused by high temperatures or the release of extinguishing agents, thereby protecting the equipment. In addition, before shutdown, the system can trigger server data backup or transfer through linkage, reducing the risk of data loss.

[0075] The fire alarm cabinet has a fire alarm reporting function, which is achieved through a sensor component. The sensor component is connected to at least one alarm signal dry contact of the fire controller. The sensor component receives the alarm signal reported by the fire controller and reports the alarm signal to the monitoring host to coordinate the control of the emergency fan in the data center.

[0076] The above describes the overall fire protection solution for the fire cabinet provided in this application embodiment. The fire cabinet provided in this application embodiment is an integrated centralized fire protection system with high integration, full functionality, intelligence, and environmental safety. The system integrates all fire protection components, monitoring components, and pipelines. The high integration and integrated design combine four major functions: detection, control, fire extinguishing, and monitoring, reducing the complexity of decentralized systems and avoiding the complex engineering required by traditional fire protection systems such as independent cylinder room and pipeline layout. It can be used immediately upon delivery, shortening the construction cycle of traditional fire protection systems.

[0077] Meanwhile, the integrated fire cabinet boasts strong flexibility, compatibility, and maintainability. Its cabinet design is consistent with the data center module's cabinet frame design, maintaining largely the same external dimensions. It can be combined with other cabinets, and its internal design isolates hot and cold aisles, ensuring consistency with the enclosed data center module and preventing gas mixing, thus maintaining system compatibility. The cabinet can operate, install, and be maintained independently, positioned at the rear of the data center module for convenient maintenance. The integrated fire cabinet saves space; its cabinet structure eliminates the need for additional cylinder rooms and fire piping systems, completely decoupling it from the server room and independently achieving fire protection functions, saving server room space. The integrated fire cabinet provides area protection within the data center module, offering precise localized fire suppression. It extinguishes fires only in the affected area, preventing the spread of fire to the entire server room, minimizing downtime and resource waste.

[0078] In addition, this fire protection system features rapid response, integrating sensitive detection technology (very early fire detection device) to trigger alarms and extinguish fires at an early stage. Furthermore, the system uses inert fire-fighting gas, ensuring non-destructive extinguishing; the extinguishing agent does not participate in chemical extinguishing reactions, leaving no residue, is non-conductive, and will not cause secondary damage to IT equipment. Operation can be quickly restored after discharge, minimizing business downtime, and it is pollution-free and environmentally friendly.

[0079] This fire cabinet is seamlessly integrated with the data center module, offering enhanced intelligence, connectivity, security, and management efficiency. The fire cabinet controller can link with the cooling units and uninterruptible power supply (UPS) modules within the data center module to enable emergency shutdowns and power cuts, preventing further fire spread and greater damage to the server room, while minimizing equipment damage and business interruption. Simultaneously, the fire protection system can be integrated with the data center module's monitoring system, providing dual security through independent protection of the fire cabinet and upper-level linkage. This ensures real-time transmission of the fire protection system's status to the client, and the upper-level monitoring system records fire alarms, actions, and faults for easy analysis and tracing.

[0080] The fire protection system also has mechanisms for handling abnormal and special scenarios. For example, it integrates an uninterruptible power supply (UPS) and exhaust fan linkage to ensure uniform diffusion of extinguishing gases within hot and cold aisles. The UPS has battery backup to prevent power outages from affecting system operation during a fire. Similarly, the fire control system is also equipped with battery backup to prevent power outages from affecting the fire protection system's operation during a fire. Furthermore, in the event of abnormal alarms or emergencies during fire sprinkler operation, the system can be manually stopped or the sprinkler system can be manually operated.

[0081] In summary, the integrated in-line fire cabinet provided in this application is a highly integrated and full-function fire protection system. It integrates various fire protection components and devices, such as fire cylinders, fire controllers, relays, pressure switches, exhaust fans, nozzles and pipes, sensors, uninterruptible power supplies, etc. It is fully functional, and only requires the installation of air sampling pipes in the module on site. Other installations are not required. It is plug-and-play and can provide an integrated fire protection module for data center solutions with tiered closed passages. Customers can configure it flexibly, and there is no need for additional on-site installation and construction. It saves space and costs, and centralized management and maintenance are simple.

[0082] Based on the same concept, embodiments of this application provide a data center, which includes: at least one integrated in-line fire cabinet as provided in embodiments of this application and at least one server cabinet, wherein the fire cabinet and the server cabinet are connected in parallel.

[0083] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
