[0026] According to an embodiment of the present application, a cooling system for a device is provided.

[0027] Figure 1 is a schematic diagram of the cooling system of the device provided by the embodiments of the present application. As Figure 1 shown, the system includes:

[0028] The first cabinet, wherein the first cabinet includes an equipment cabinet, an equipment slot, a liquid circulation pump and a liquid storage tank. The equipment cabinet is immersed in the equipment slot filled with insulating coolant. The liquid circulation pump is configured to transfer the insulating coolant in the equipment slot to the second cabinet through a liquid output pipeline and transfer the insulating coolant stored in the liquid storage tank to the equipment slot when receiving a first start instruction sent by the control center.

[0029] Specifically, the first cabinet is an integrated system integrating liquid cooling technology and equipment, and can be an indoor liquid cooling cabinet for placing equipment indoors. It mainly consists of the following parts:

[0030] Equipment cabinet: It is the core part of the cabinet and is used to accommodate IT equipment that needs to be cooled, such as 5G BBU (Base Band Unit, baseband processing unit). When designing the equipment cabinet, the installation and maintenance requirements of the equipment and the integration of the liquid cooling system are considered.

[0031] Equipment slot: The equipment slot is the part in the first cabinet for containing insulating coolant. The IT equipment is directly immersed in the coolant in the equipment slot, and heat exchange is carried out through direct contact to reduce the equipment temperature.

[0032] Liquid circulation pump: The liquid circulation pump located inside the cabinet is one of the key components of the liquid cooling system. Its function is to drive the coolant to circulate between the equipment slot, the second cabinet (outdoor heat exchanger) and the liquid storage tank after receiving an instruction from the control center. To ensure the reliability of the system, usually 1 main pump and 1 standby pump are configured, and its status and performance need to be monitored during operation.

[0033] Liquid storage tank: The liquid storage tank is a part of the cabinet and is used to store additional insulating coolant to supplement the liquid level drop caused by evaporation or leakage, ensuring the stable operation of the liquid cooling system. The liquid storage tank is usually connected to the equipment slot, and the coolant can be transferred from the liquid storage tank to the equipment slot through the liquid circulation pump, and automatic liquid replenishment and liquid addition actions in daily and emergency states can be realized. To meet the need of long-term unattended operation.

[0034] It should be noted that the indoor liquid-cooled cabinet is the core component in the entire system to achieve the liquid-cooling process. It is used to install the 5G BBU and provide an immersion liquid-cooling environment for the 5G BBU, which can solve the heat dissipation problems in the scenarios of a large concentration of 5G BBUs in the C-Ran (Cloud Radio Access Network) scenario and high power density scenarios. The installation of the immersion liquid-cooling unit should be reasonably laid out. Before installation, the installation positions of each component and the routing path of the liquid pipes should be planned well. The liquid pipes should be installed neatly and reliably without affecting the installation and maintenance of other equipment in the computer room. Each component of the immersion liquid-cooling unit should be firmly fixed, and corresponding pipe clamps, expansion bolts, etc. should be used for fastening connections.

[0035] The indoor cabinet should meet the following requirements: There should be two inlet ports in the indoor liquid-cooled cabinet, corresponding to two power cables, network cables, fiber optic cables and other wiring channels respectively. The fiber optic inlet and outlet of the indoor liquid-cooled cabinet should meet the requirement of no less than 416 single-core fiber optic cables for wiring. There should be sufficient space and devices for coiling the redundant optical fibers in the indoor liquid-cooled cabinet. The indoor liquid-cooled cabinet should reserve an installation space for no less than 12 groups of passive wavelength division multiplexers outside the liquid-cooling tank. There should be a standard liquid level monitoring device in the indoor liquid-cooled cabinet to monitor the liquid level status and provide it to the monitoring system. Two removable and replaceable 48V DC power distribution units should be equipped in the indoor liquid-cooled cabinet for the introduction, distribution and plugging of the power supply of the communication equipment in the cabinet, and an electric energy meter can be configured to monitor the total current / voltage, etc. of the connected communication equipment. There should be an impurity filtering device in the indoor liquid-cooled cabinet to filter the impurities in the coolant. The indoor liquid-cooled cabinet should have a usable capacity of no less than 16U. The indoor liquid-cooled cabinet is internally equipped with a lighting device. The indoor liquid-cooled cabinet should support the power-on maintenance during the maintenance of the BBU and its boards; the immersion liquid-cooling system should support the online maintenance of the BBU, and the disassembly of a single BBU frame does not affect the operation of other BBUs in the same box; the immersion liquid-cooling system should support the hot plugging of the boards, and the maintenance does not affect the operation of other boards in the same frame. The depth of the internal liquid pool of the indoor liquid-cooled cabinet should not be less than the depth of the installed BBU equipment.

[0036] The control center is used to send a first start command to the liquid circulation pump when it detects that the temperature of the insulating coolant in the equipment tank is greater than the preset temperature threshold.

[0037] Specifically, the control center is responsible for monitoring and controlling the operating status of the liquid-cooling system. Its core function is to continuously monitor the temperature of the insulating coolant in the equipment tank to ensure that it remains within the preset safe range. And when it detects that the temperature of the coolant in the equipment tank exceeds the preset temperature threshold, the control center will immediately send a first start command to the liquid circulation pump, instructing the pump to start working and transfer the high-temperature coolant to the second cabinet for cooling, thereby reducing the temperature of the equipment tank and protecting the equipment from overheating damage.

[0038] The second cabinet includes a heat exchanger. The heat exchanger is used to cool the insulating coolant transferred by the liquid output pipeline, and transfer the cooled insulating coolant to the liquid storage tank through the liquid input pipeline.

[0039] Specifically, the second cabinet can be an outdoor cabinet, which is used to place the heat exchanger for heat exchange operation, so as to cool the coolant. Among them, the heat exchanger is the core component of the second cabinet. Its function is to exchange heat with the high-temperature insulating coolant from the first cabinet, transfer the heat to the external cooling medium (usually air or water), so as to reduce the temperature of the coolant to an appropriate level.

[0040] In this process, the insulating coolant flows from the equipment tank of the first cabinet to the heat exchanger of the second cabinet through the liquid output pipeline. After being cooled in the heat exchanger, it returns to the liquid storage tank of the first cabinet through the liquid input pipeline. Through the coordinated work of the first cabinet and the second cabinet, the entire liquid cooling system can effectively control the equipment temperature, improve the energy efficiency ratio, reduce the energy consumption, and ensure the stable operation of the system.

[0041] It should be noted that in order to ensure the normal operation of each device in the system, the following requirements can be set:

[0042] 1. The protection level of the indoor liquid cooling cabinet reaches IP4X; the protection level of the outdoor machine system reaches IP44.

[0043] 2. The load-bearing requirement of the indoor equipment on the floor should be ≤ 600 kg / m2; the load-bearing requirement of the outdoor equipment on the roof should be ≤ 200 kg / m2.

[0044] 3. The cabinet door panels and side panels of the equipment cabinet are flat, without distortion, deformation, or obvious vibration, and the screw holes on the door panels are evenly opened. All hinges and door locks of the movable door panels are made of corrosion-resistant materials. The door locks use universal locks, and the lock cores are equipped with protective covers, which are safe and reliable. The cabinet door can be flexibly opened, and the opening angle is greater than 90 degrees.

[0045] 4. Interface technical requirements: (1) 48V power supply introduction interface for communication equipment: Two 48V DC power supply introduction interfaces need to be reserved inside the indoor liquid cooling cabinet. (2) 485 communication interface: A Modbus485 communication interface needs to be reserved inside the liquid pump circulation system. (3) Dynamic loop introduction interface: The cabinet system can be connected to the existing dynamic loop monitoring and management system according to the telecom interface specifications of the Chengdu Branch.

[0046] 5. The control center monitors the temperature data, pressure data, flow data, valve opening and closing state data, etc. of the coolant entering and leaving the liquid, and has the function of reporting faults and alarms.

[0047] The cooling system of the device provided by the embodiment of the present application adopts: a first cabinet, where the first cabinet includes an equipment cabinet, an equipment slot, a liquid circulation pump, and a liquid storage tank. The equipment cabinet is immersed in the equipment slot filled with insulating coolant. The liquid circulation pump is used to transfer the insulating coolant in the equipment slot to the second cabinet through a liquid output pipeline and transfer the insulating coolant stored in the liquid storage tank to the equipment slot when receiving a first start instruction sent by the control center; a control center, which is used to send a first start instruction to the liquid circulation pump when it monitors that the temperature of the insulating coolant in the equipment slot is greater than a preset temperature threshold; a second cabinet, including a heat exchanger, where the heat exchanger is used to cool down the insulating coolant transferred by the liquid output pipeline and transfer the cooled insulating coolant to the liquid storage tank through a liquid input pipeline. This solves the problem of low energy efficiency conversion rate in the related technology where the device uses air cooling method for cooling. By placing the equipment cabinet in the insulating coolant and using the liquid circulation pump to circulate the insulating coolant, during the circulation process, the heat of the equipment in the equipment cabinet is transferred by the insulating coolant, thereby achieving the effect of improving the cooling efficiency and energy efficiency conversion rate of the equipment cabinet.

[0048] Optionally, in the cooling system of the device provided by the embodiment of the present application, the insulating coolant is a perfluoroalkane liquid, the hydrogen content of the insulating coolant is less than a first preset threshold, and the thermal conductivity of the insulating coolant is greater than a second preset threshold.

[0049] Specifically, since the coolant in the equipment slot in the cooling system directly contacts the electronic equipment in the equipment cabinet and conducts heat exchange, the insulating coolant needs to be a perfluoroalkane liquid, and the hydrogen content of the insulating coolant is less than a first preset threshold, such as 0.1 PPM. And since the properties of the coolant directly affect the heat transfer efficiency and operation reliability of the system, the coolant of the immersion liquid cooling system should have the following characteristics: Safety: The coolant has no flash point, no explosion point, no corrosion, is not flammable, and is not volatile; Thermodynamic performance: The coolant has good thermodynamic performance as a heat transfer medium, that is, the thermal conductivity of the insulating coolant is greater than a second preset threshold; Stability: The coolant has good stability in the set operating environment; Insulation: The coolant should have a certain insulation property and is not easily soluble in other conductive substances. Material compatibility: The coolant should not have an adverse impact on the main materials used on the electronic information equipment and the environment.

[0050] Optionally, in the cooling system of the device provided by the embodiment of the present application, the system further includes: a filter, arranged on the liquid input pipeline, for filtering the insulating coolant after the heat exchanger cools it down.

[0051] Specifically, the filter is a key component in the liquid cooling system for ensuring the purity of the coolant. It is installed on the liquid input pipeline, between the heat exchanger in the second cabinet and the liquid storage tank in the first cabinet. After the heat exchanger cools down the insulating coolant, the coolant will return to the liquid storage tank in the first cabinet through the liquid input pipeline. At this time, the filter will finely filter the returned coolant to remove the tiny particles, dust, and other impurities that may accumulate during the cooling and circulation processes.

[0052] Through the filtering function of the filter, impurities can be prevented from entering the equipment tank, avoiding potential damage to the IT equipment immersed in the coolant. The accumulation of impurities may lead to a decrease in the heat conduction efficiency, and even block the pipeline, reducing the operating efficiency and stability of the liquid cooling system. At the same time, the pure coolant can reduce the corrosion of the internal metal components of the equipment, extend the service life of the coolant, and also protect the equipment from wear caused by pollutants, thus improving the service life of the liquid cooling system and IT equipment as a whole.

[0053] In summary, the setting of the filter can not only protect the equipment from pollution, but also ensure the long-term stability and high-efficiency operation of the system. Through the effective operation of the filter, the comprehensive performance of the liquid cooling system can be significantly improved, including but not limited to aspects such as energy consumption reduction, equipment operation stability, and system maintenance convenience.

[0054] Optionally, in the cooling system of the equipment provided in the embodiment of the present application, the control center is further configured to obtain temperature data, liquid flow rate data, liquid level height data, and the operation data of the liquid circulation pump, and generate an alarm message when there is abnormal data.

[0055] It should be noted that the control center is used to control, monitor, and output the overall operation of the liquid cooling system, and has the ability to dock system information. It can realize the control function of starting the liquid cooling system, and has a locking or reminder function when shutting down to avoid misoperation. Obtain the control commands of the operator's intelligent system to realize remote operation of the system, including: starting and stopping, adjusting the rotation speed / flow rate, switching between the main and standby liquid pumps, etc.

[0056] Specifically, in order to ensure the comprehensive and accurate monitoring of the cooling system, the control center can be remotely connected to the remote monitoring system according to the monitoring requirements to realize the remote monitoring and management of the cooling system through the control center. That is, configure the equipment host of the control center in the indoor cabinet to realize on-site data viewing and management. The control center equipment should meet the following requirements:

[0057] The control center device needs to have the ability to upload system operation index data to achieve remote alarm monitoring, performance summary, and log analysis. The performance data may include: inlet / outlet liquid temperature, flow rate, hydraulic pressure, pump speed, external unit speed, etc. The alarm data includes: downtime alarm, temperature threshold alarm, pump operation alarm, flow rate alarm, low hydraulic pressure alarm, etc. Log management: system logs, operation logs, etc. Moreover, the control center device should have the function of storing a large amount of fault alarm records to store historical alarm information, so that the cooling system can be overall managed and fault analyzed based on the stored information.

[0058] Optionally, in the cooling system of the device provided in the embodiment of the present application, the system further includes: temperature sensors configured in the device slot and the liquid storage tank to monitor the temperature data of the insulating coolant in the device slot and the liquid storage tank and synchronize the temperature data to the control center; flow sensors configured in the liquid output pipeline and the liquid input pipeline to monitor the liquid flow rate data in the liquid output pipeline and the liquid input pipeline and synchronize the liquid flow rate data to the control center; liquid level sensors configured in the device slot and the liquid storage tank to monitor the liquid level height data of the insulating coolant in the device slot and the liquid storage tank and synchronize the liquid level height data to the control center.

[0059] Specifically, in order to monitor the cooling system, different types of sensors need to be set at multiple positions, including temperature sensors, flow sensors, and liquid level sensors. Among them, the temperature sensors can be set in the device slot, the liquid storage tank, and the pipeline to continuously monitor the temperature of the insulating coolant in each area. These sensors can provide real-time temperature data to ensure the efficient operation of the liquid cooling system and the safety of the device. Moreover, the temperature sensors transmit the temperature data to the control center in real time. When it is detected that the coolant temperature rises abnormally, the control center can quickly respond, start the liquid circulation pump, and direct the overheated coolant to the heat exchanger of the second cabinet for cooling, effectively avoiding the performance degradation and potential damage caused by overheating of the device.

[0060] Furthermore, the flow sensors are set in the liquid output pipeline and the liquid input pipeline to accurately measure the flow rate of the coolant, so as to ensure that the heat inside the system can be quickly and evenly transmitted and processed. The data monitored by the flow sensors can help the control center check whether the coolant circulation is smooth, whether there are signs of blockage or leakage, and ensure the cooling efficiency of the liquid cooling system. Based on the flow rate data, the control center can adjust the operation parameters of the liquid circulation pump, such as speed, to ensure that the flow rate of the coolant meets the heat dissipation requirements of the device while avoiding excessive energy consumption.

[0061] Furthermore, the liquid level sensors are placed in the equipment tank and the liquid storage tank. Their function is to continuously monitor the liquid level of the coolant, ensure that the inventory of the coolant in the system is within a safe and effective range, prevent the system performance from being affected or potential safety hazards from being caused due to insufficient or overflow of the coolant. The data of the liquid level sensors is synchronized to the control center. When the detected liquid level is lower than the preset safety threshold, the system can automatically start the liquid replenishment process to supplement the coolant from the liquid storage tank to the equipment tank; on the contrary, if the liquid level is too high, the system can stop or reduce the operation of the liquid circulation pump to avoid coolant overflow. Through the monitoring of the liquid level data, the control center can give early warnings about the maintenance work that needs to be carried out, such as regularly checking the consumption and replenishment of the coolant, to ensure the long-term stable operation of the liquid cooling system.

[0062] It should be noted that sensors can also be set to monitor the contents listed in Table 1:

[0063] Table 1

[0064]

[0065] In this embodiment, by setting temperature sensors, flow sensors and liquid level sensors, comprehensive data support is provided for the real-time monitoring and intelligent management of the liquid cooling system. These sensors can not only ensure the safe operation of the system by preventing overheating, ensuring circulation efficiency and maintaining stable liquid level, but also optimize the system performance in real time, reduce energy consumption and improve cooling efficiency. In addition, the data feedback mechanism of the sensors simplifies the maintenance process, reduces the operation cost, and overall improves the reliability and economy of the liquid cooling system, providing a strong technical guarantee for the efficient cooling of data centers and high-power density equipment.

[0066] Optionally, in the cooling system of the equipment provided in the embodiment of the present application, the system further includes: a liquid leakage detection device, which is arranged below the first cabinet, the second cabinet, the liquid output pipeline and the liquid output pipeline, and is used to detect whether there is a liquid leakage phenomenon in the first cabinet, the second cabinet, the liquid output pipeline and the liquid output pipeline, and in the case of a liquid leakage phenomenon, send the name of the equipment with the liquid leakage phenomenon to the control center.

[0067] Specifically, the liquid leakage detection device is installed below the first cabinet, the second cabinet, and the liquid output pipeline and the liquid input pipeline, and is used to continuously monitor whether these key components have coolant leakage. In the liquid cooling system, any leakage may not only damage the operating environment of IT equipment, but also cause safety problems, such as electrical short circuits. Therefore, it is very necessary to detect the liquid leakage phenomenon in a timely and accurate manner.

[0068] When a liquid leakage is detected, the liquid leakage detection device can immediately notify this emergency situation to the control center and accurately indicate the specific location of the liquid leakage, such as which cabinet and which section of the pipeline have problems. This enables the maintenance team to respond quickly, isolate the faulty area in a timely manner, and prevent further spread of damage.

[0069] Through continuous monitoring, the liquid leakage detection device helps to achieve preventive maintenance and reduce the probability of sudden failures. The liquid leakage detection device can detect potential leakage hazards in the initial stage, allowing the system administrator to take actions before the problem worsens, repair or replace faulty components, thereby enhancing the overall safety and reliability of the liquid cooling system.

[0070] It should be noted that since the insulating coolant is usually expensive and may contain environmentally sensitive components, the use of the liquid leakage detection device helps to promptly prevent the waste of coolant and avoid the negative environmental impacts that the leakage may cause.

[0071] In this embodiment, by deploying the liquid leakage detection device, the stability and safety of the liquid cooling system throughout its life cycle are enhanced. It can not only quickly detect and locate the coolant leakage to ensure the accuracy and efficiency of maintenance work, but also improve the overall operation efficiency of the system by reducing unplanned downtime and maintenance costs.

[0072] Optionally, in the cooling system of the device provided in the embodiment of the present application, the system further includes: a standby liquid circulation pump, arranged in the first cabinet, for transferring the insulating coolant in the first cabinet to the second cabinet through the liquid output pipeline when receiving the second start instruction sent by the control center; and / or, a standby power supply, arranged in the first cabinet, for supplying power to the first cabinet when the main power supply of the first cabinet is abnormal.

[0073] Specifically, the standby liquid circulation pump is a key device to ensure high reliability and continuity in the liquid cooling system. It is installed inside the first cabinet and is used to immediately start and take over the task of coolant circulation after receiving the second start instruction from the control center when the main liquid circulation pump fails or needs maintenance, and transport the insulating coolant in the first cabinet to the second cabinet for heat dissipation treatment through the liquid output pipeline.

[0074] The presence of a standby pump greatly enhances the availability and continuous operation ability of the liquid cooling system. When the main pump fails, the standby pump can start quickly, avoiding the interruption of the coolant circulation, preventing equipment overheating, and thus ensuring the stable operation of IT equipment. When the main pump fails, the standby pump can switch seamlessly, reducing the equipment downtime caused by the interruption of the coolant circulation and avoiding the economic losses and the decline of customer experience brought by business interruption. When the main pump needs preventive maintenance or fault repair, the standby pump can be immediately put into operation, so that the maintenance work of the main pump can be carried out without affecting the overall system, simplifying the maintenance process and reducing the maintenance cost. The configuration of the standby pump enables the liquid cooling system to have stronger response and recovery capabilities in the face of emergencies, enhancing the overall flexibility and adaptability of the system.

[0075] Furthermore, in the first cabinet, a standby power supply (usually an uninterruptible power supply UPS or a battery pack) also needs to be configured to immediately supply power to the first cabinet when the main power supply (such as grid power supply) has an abnormality (such as power failure, instability, etc.), ensuring the normal operation of the liquid cooling system.

[0076] The standby power supply can respond quickly when the main power supply fails, supply power to the equipment in the first cabinet, ensure the continuity of the coolant circulation, and thus maintain the stability of the system. Since the instantaneous interruption of the power supply may cause data loss or equipment damage, the presence of the standby power supply can prevent these situations from occurring, protecting the integrity of the data and the safety of the equipment. The standby power supply enables the system to quickly resume normal operation after the main power supply fails, reducing the maintenance time and cost caused by power problems and enhancing the fault recovery ability of the liquid cooling system. By configuring the standby power supply, the liquid cooling system in the first cabinet can achieve high availability, and can maintain the efficient cooling of key IT equipment even when the power supply is unstable or interrupted, improving the availability and reliability of the entire data center.

[0077] In this embodiment, by deploying a standby liquid circulation pump and a standby power supply, the overall stability and fault response ability of the liquid cooling system are greatly enhanced. The standby pump ensures the uninterrupted coolant circulation, while the standby power supply ensures that the system can still operate continuously when the main power supply is abnormal. This redundant design not only improves the operation efficiency of IT equipment, reduces business interruptions caused by system failures, but also reduces the complexity and cost of system maintenance through preventive measures and immediate responses, providing strong technical support for building a highly reliable data center environment.

[0078] Optionally, in the cooling system of the device provided in the embodiment of the present application, the control center is further configured to monitor the valve opening and closing state data of the liquid output pipeline and the liquid output pipeline, and adjust the opening and closing degrees of the valves of the liquid output pipeline and the liquid output pipeline according to the control instruction when receiving the control instruction.

[0079] Specifically, the control center is not only responsible for receiving data from sensors, but also has the ability to monitor the valve states on the liquid output pipeline and the liquid input pipeline. This means that it can track the opening and closing states of these valves in real time to ensure the normal progress of liquid circulation. More importantly, the control center can respond to control instructions generated externally or internally, adjust the opening degree of the valves according to the instructions, and thus precisely control the coolant flow rate to meet the cooling requirements in different situations.

[0080] By adjusting the valve opening degree, the control center can optimize the coolant flow rate, dynamically adjust the circulation speed of the coolant according to the temperature, flow rate, equipment load, etc. monitored in real time, ensure efficient and precise heat dissipation effects, not only improve the cooling efficiency, but also reduce energy consumption to achieve the purpose of energy conservation and emission reduction. And monitoring the valve opening and closing states can help detect potential faults in a timely manner, such as valve jamming, leakage and other problems. Once an abnormality is detected, the control center can immediately adjust the valve opening degree or even close the affected pipeline to prevent coolant loss, thereby protecting the equipment from damage and reducing system downtime.

[0081] The control center can balance the coolant distribution between the first cabinet and the second cabinet by finely adjusting the valve opening degree to ensure that each cooling unit can obtain appropriate cooling effects. This helps to optimize the heat dissipation performance of the entire system, extend the equipment life, and improve the operation efficiency of the data center.

[0082] In this embodiment, through the monitoring and adjustment of the valve states on the liquid output pipeline and the liquid input pipeline by the control center, not only the refined management of the coolant flow rate is realized, the efficient heat dissipation of the system is ensured, but also through functions such as fault prevention, system optimization, and intelligent operation and maintenance, the overall stability and operation and maintenance convenience of the liquid cooling system are improved, the operation and maintenance costs are reduced, and a strong technical guarantee is provided for the efficient operation of the data center.

[0083] The embodiment of the present application also provides a cooling method for a device. It should be noted that the cooling method for the device in the embodiment of the present application can be applied to the cooling system for the device provided in the embodiment of the present application. Figure 2 is a flowchart of the cooling method for the device provided in the embodiment of the present application, as Figure 2 shown, the method includes:

[0084] Step S201, monitor the temperature data of the insulating coolant in the device slot, and determine whether the temperature data is greater than the temperature threshold, where the device slot is located in the first cabinet, and the first cabinet includes an equipment cabinet, a device slot, a liquid circulation pump, and a liquid storage tank, and the equipment cabinet is immersed in the device slot containing the insulating coolant.

[0085] Specifically, the execution entity of this embodiment is the control center. The control center first uses the temperature sensors set in the equipment tank to monitor the real-time temperature data of the insulating coolant therein. Here, the equipment tank is located in the first cabinet, and the first cabinet is an integrated unit integrating multiple key components, including an equipment cabinet, an equipment tank, a liquid circulation pump, and a liquid storage tank. The equipment cabinet is immersed in the equipment tank filled with insulating coolant. After the monitoring, the system will automatically determine whether these temperature data exceed the preset temperature threshold.

[0086] Through step S201, the system can continuously track the temperature of the insulating coolant, ensuring real-time monitoring of the cooling effect of the equipment. Once the temperature data exceed the set threshold, the system can immediately identify the temperature anomaly and trigger subsequent emergency responses, such as starting the liquid circulation pump to prevent the equipment from overheating and ensuring the safe and stable operation of IT equipment.

[0087] Step S202, in the case where the temperature data is greater than the temperature threshold, start the liquid circulation pump. Here, the liquid circulation pump is used to transfer the insulating coolant in the equipment tank to the second cabinet through the liquid output pipeline.

[0088] Specifically, when the system monitors that the coolant temperature in the equipment tank is higher than the preset temperature threshold, it will automatically start the liquid circulation pump in the first cabinet. Thus, the overheated insulating coolant is pumped out of the equipment tank by the liquid circulation pump and transported through the liquid output pipeline to the heat exchanger in the second cabinet for cooling treatment. Then, the cooled liquid is sent back to the liquid storage tank in the first cabinet to provide cooling service for the equipment tank again, thereby quickly responding to the temperature anomaly, transferring the overheated coolant to the second cabinet for processing, preventing the equipment temperature from continuing to rise, and avoiding the decline or damage of equipment performance.

[0089] Through the action of the circulation pump, the overheated coolant is effectively transferred to the heat exchanger in the second cabinet, and efficient heat exchange is carried out using the external cold source to achieve rapid cooling of the coolant, improving the heat dissipation efficiency of the liquid cooling system. The automation of this process reduces the need for manual intervention. The start of the liquid circulation pump and the transfer of the coolant are automatically completed by the system, reflecting the intelligent control ability of the liquid cooling system and improving the operation and maintenance efficiency and the overall reliability of the system.

[0090] The cooling method for the device provided by the embodiment of the present application monitors the temperature data of the insulating coolant in the device tank and determines whether the temperature data is greater than the temperature threshold. Here, the device tank is located in the first cabinet, and the first cabinet includes an equipment cabinet, a device tank, a liquid circulation pump, and a liquid storage tank. The equipment cabinet is immersed in the device tank filled with the insulating coolant. When the temperature data is greater than the temperature threshold, the liquid circulation pump is started. The liquid circulation pump is used to transfer the insulating coolant in the device tank to the second cabinet through the liquid output pipeline, solving the problem of low energy efficiency conversion rate in the related technology where the device is cooled by the air-cooling method. By monitoring the cooling parameters in the first cabinet, when the temperature is determined to be abnormal, the coolant is controlled to flow in time to take out the temperature, thereby achieving the effect of improving the cooling efficiency and energy efficiency conversion rate of the equipment cabinet.

[0091] Optionally, in the cooling method for the device provided by the embodiment of the present application, the method further includes: monitoring the liquid level height of the insulating coolant in the device tank and determining whether the liquid level height is greater than the first height threshold; when the liquid level height is greater than the first height threshold, starting the liquid circulation pump until the liquid level height is less than or equal to the first height threshold; when the liquid level height is less than or equal to the first height threshold, determining whether the liquid level height is less than the second height threshold, where the first height threshold is greater than the second height threshold; when the liquid level height is less than the second height threshold, controlling the liquid storage tank to add insulating coolant to the device tank until the liquid level height is between the first height threshold and the second height threshold.

[0092] Specifically, the control center can also use a liquid level sensor to monitor the liquid level height of the insulating coolant in the device tank. Here, the device tank is located in the first cabinet, which is the core part of the system and contains the insulating coolant for cooling IT equipment. After monitoring the liquid level height, the system will determine whether this height exceeds the preset first height threshold.

[0093] If the monitored liquid level height exceeds the first height threshold, the control center will start the liquid circulation pump. The liquid circulation pump transfers the insulating coolant in the device tank to the heat exchanger in the second cabinet for cooling treatment and then sends it back to the liquid storage tank. This process will continue until the liquid level height in the device tank drops to equal to or below the first height threshold. When the liquid level height in the device tank is less than or equal to the first height threshold, the control center further determines whether the liquid level height is less than the second height threshold. The second height threshold is set lower than the first height threshold as a safety liquid level lower limit. Once the liquid level height is less than the second height threshold, the control center will control the liquid storage tank to add insulating coolant to the device tank until the liquid level height rises back between the first height threshold and the second height threshold, thereby ensuring the accuracy of the liquid level height, the safety and stability of the insulating coolant in the device, and the safe operation of the device.

[0094] In this embodiment, by constructing a set of liquid level monitoring and automatic adjustment mechanisms, it not only helps to maintain the liquid level of the coolant in the equipment tank within a safe and effective range, ensuring the stable operation and efficient cooling of the cooling system, but also reduces the maintenance cost and improves the operation efficiency and security of the data center or IT equipment through intelligent management and control.
