These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0056] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the preferred embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] It should be noted that in the description of the embodiments of the present application, terms such as "upper", "lower", "inside", and "outside" indicating orientation or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description. They do not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0058] In addition, it should be noted that the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0059] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," and "fixed" should be interpreted broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0060] Because integrated power supply equipment generates significant heat during operation, power rooms are typically equipped with air conditioners to reduce the temperature. However, current air conditioners have a short air delivery distance, resulting in poor heat dissipation at the end of the integrated power supply equipment farthest from the air conditioner, which can easily lead to localized hot spots. Furthermore, the airflow distribution within the power room is relatively chaotic, resulting in poor energy efficiency.

[0061] In view of this, the power room thermal management system provided by the present application includes an integrated power supply device arranged at intervals along a first direction, and the integrated power supply device includes a plurality of power devices arranged side by side along a second direction. Each integrated power supply device is provided with a hot channel on one side along the first direction and a cold channel on the other side. The cold air inlet of the power equipment is connected to the cold channel, and the heat exhaust port of the power equipment is connected to the hot channel. Through the isolation between the cold channel and the hot channel, the cold air and the hot air are isolated, thereby improving the cooling effect of the air conditioning device. The air conditioning device includes an air conditioning terminal, the return air port of the air conditioning terminal is connected to the hot channel, and the air outlet of the air conditioning terminal is connected to the cold channel. By embedding each air conditioning terminal into the integrated power supply device, the cold air enters the cold channel through the air outlet of the air conditioning terminal, and then efficiently dissipates the heat of the power equipment through the cold channel, and then the hot air is discharged into the hot channel through the heat exhaust port. The air conditioning terminal embedded in the integrated power supply device can dissipate heat for each power device at a close distance, thereby improving the heat dissipation effect and avoiding the occurrence of local hot spots. In addition, through the isolation between the cold channel and the hot channel, and the corresponding setting of the return air inlet and the hot channel, and the air outlet and the cold channel, the air flow organization at the air-conditioning terminal is more orderly, effectively reducing the energy consumption of the air-conditioning device.

[0062] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] See also Figures 1 to 17 The present application provides a thermal management system for a power room, comprising an integrated power supply device 100 and an air conditioning unit. The integrated power supply devices 100 are arranged in multiple rows spaced apart along a first direction. Each row of integrated power supply devices 100 includes multiple power supply devices 110 arranged side by side along a second direction. Each integrated power supply device 100 is provided with a hot aisle 120 on one side along the first direction and a cold aisle 130 on the other side. The power supply device 110 has a cold air inlet and a heat exhaust outlet. The cold air inlet communicates with the cold aisle 130, and the heat exhaust outlet communicates with the hot aisle 120. The first direction is perpendicular to the second direction. The air conditioning unit includes an air conditioning terminal 210. Each row of integrated power supply devices 100 is embedded with several air conditioning terminals 210 of the air conditioning unit. The air conditioning terminal 210 has a return air inlet 211 and an air outlet 212. The return air inlet 211 communicates with the hot aisle 120, and the air outlet 212 communicates with the cold aisle 130.

[0064] The first direction corresponds to Figure 1 The X-axis direction in the second direction corresponds to Figure 1 The Y-axis direction in .

[0065] It should be noted that multiple rows of integrated power supply devices 100 are arranged in a spaced-apart arrangement along a first direction defined within the equipment room. Within each row of integrated power supply devices 100, multiple power equipment 110 are closely arranged side by side along a second direction perpendicular to the first direction. The multiple power equipment 110 may include a power distribution cabinet 112, a transformer 113, a high-voltage cabinet 114, etc. The power distribution cabinet 112, transformer 113, and high-voltage cabinet 114 may be arranged in spaced-apart arrangement, although this embodiment is not limited thereto.

[0066] Furthermore, a hot channel 120 and a cold channel 130 are provided on both sides of the integrated power supply device 100. The hot channel 120 is located on one side of the integrated power supply device along the first direction, and is used to collect and centrally process the high-temperature air exhausted by the power equipment 110; while the cold channel 130 is located on the other side, and provides low-temperature air for cooling the power equipment 110. The power equipment 110 is designed with a cold air inlet (not shown in the figure) and a heat exhaust port (not shown in the figure). The cold air inlet is connected to the cold channel 130 to ensure that cold air can smoothly enter the interior of the power equipment 110; the heat exhaust port is connected to the hot channel 120 to effectively discharge the heat generated by the power equipment 110. In this way, a clear hot and cold air circulation path is formed in the power room, which isolates the cold air and the hot air, improves the cooling effect of the air conditioning device on each power equipment 110, and reduces the energy consumption of the air conditioning.

[0067] In order to further improve the efficiency of thermal management, an air conditioning device is embedded in the integrated power supply device 100. Specifically, a number of air conditioning terminals 210 are embedded inside each column of integrated power supply devices 100. Each air conditioning terminal 210 has a return air inlet 211 and an air outlet 212. The return air inlet 211 is connected to the hot channel 120 and is configured to inhale the hot air exhausted by the power equipment 110 for heat exchange processing within the air conditioning device; the air outlet 212 is configured to be connected to the cold channel 130, and the low-temperature air cooled by the air conditioning device is sent to the cold channel 130 to provide continuous cooling support for the power equipment 110. By embedding the air conditioning terminal 210 in the integrated power supply device 100, the distance between the air conditioning terminal 210 and the heat-generating components of the integrated power supply device 100 is shortened. In other words, the air conditioning terminal 210 can dissipate heat from each power equipment 110 at a close distance, thereby improving the heat dissipation effect and avoiding the occurrence of local hot spots. In addition, through the isolation between the cold channel 130 and the hot channel 120, and the corresponding setting of the return air outlet 211 and the hot channel 120, and the air outlet 212 and the cold channel 130, the air flow organization of the air-conditioning terminal 210 is more orderly, effectively reducing the energy consumption of the air-conditioning device.

[0068] In this way, the thermal management system of the power room achieves complete isolation and efficient circulation of hot and cold air, effectively reduces the operating temperature of the power equipment 110, extends the service life of the power equipment 110, and significantly improves the overall energy efficiency ratio of the air conditioner in the room.

[0069] See also Figure 2 In the embodiment of the present application, the heat channel 120 is located between two adjacent columns of integrated power supply devices 100 .

[0070] With this design, the heat generated by the integrated power supply device 100 during operation is concentrated into the heat channel 120 through physical isolation, thereby effectively avoiding disorderly diffusion of heat and local hot spots inside the power room.

[0071] Specifically, see Figure 7 、 Figure 13 and Figure 15 The power equipment 110 of the integrated power supply device 100 may have its cold air inlet located at the front of the power equipment 110 (i.e., the side of the integrated power supply device 100 facing away from the hot channel 120), and its heat exhaust port may be located at the rear of the power equipment 110 (i.e., the side of the integrated power supply device 100 facing the hot channel 120). In this way, the cold air generated by the air-conditioning terminal 210 enters the cold channel 130, and then the cold air enters the integrated power supply device 100 through the cold air inlet to dissipate heat and cool down each power equipment 110, and then the hot air in the power equipment 110 enters the hot channel 120 through the heat exhaust port.

[0072] See also Figure 9 and Figure 11 The power equipment 110 of the integrated power supply device 100 can have its cold air inlet located at the front of the power equipment 110 (i.e., the side of the integrated power supply device 100 facing away from the hot channel 120), and its heat exhaust port can be located above the power equipment 110. In this way, the cold air generated by the air-conditioning terminal 210 enters the cold channel 130, and then the cold air enters the integrated power supply device 100 through the cold air inlet to dissipate heat and cool down each power equipment 110. Subsequently, the hot air in the power equipment 110 is discharged through the heat exhaust port and then enters the hot channel 120.

[0073] See also Figure 1 In the embodiment of the present application, the heat channel 120 is located on the side of two adjacent rows of integrated power supply devices 100 facing away from each other.

[0074] This effectively isolates hot and cold air. A thermal barrier forms between the hot aisle 120 and the integrated power supply 100, separating the hot air from the cold air in the cold aisle 130. This keeps the cold air cool, more effectively cooling the integrated power supply 100. Meanwhile, the hot air flows through the hot aisle 120 into the air conditioning unit for cooling, creating a healthy airflow cycle.

[0075] See also Figure 6 、 Figure 12 and Figure 14 The cold air inlet of the power equipment 110 of the integrated power supply device 100 can be located at the front of the power equipment 110 (i.e., the side of the integrated power supply device 100 facing away from the hot channel 120), and the heat exhaust port can be located at the rear of the power equipment 110 (i.e., the side of the integrated power supply device 100 facing the hot channel 120). In this way, the cold air generated by the air-conditioning terminal 210 enters the cold channel 130, and then the cold air enters the integrated power supply device 100 through the cold air inlet to dissipate heat and cool down each power equipment 110. Then, the hot air in the power equipment 110 is discharged through the heat exhaust port and then enters the hot channel 120.

[0076] See also Figure 8 and Figure 10 The power equipment 110 of the integrated power supply device 100 can have its cold air inlet located at the front of the power equipment 110 (i.e., the side of the integrated power supply device 100 facing away from the hot channel 120), and its heat exhaust port can be located above the power equipment 110. In this way, the cold air generated by the air-conditioning terminal 210 enters the cold channel 130, and then the cold air enters the integrated power supply device 100 through the cold air inlet to dissipate heat and cool down each power equipment 110. Subsequently, the hot air in the power equipment 110 is discharged through the heat exhaust port and then enters the hot channel 120.

[0077] See also Figure 6 In the embodiment of the present application, a partition 300 is also included, and the partition 300 and the shell of the power equipment 110 together define a heat channel 120.

[0078] The partitions 300 effectively isolate hot air between adjacent rows of integrated power supply devices 100, preventing the disorderly diffusion of heat within the equipment room. The partitions 300 also serve as the physical boundaries of the hot aisles 120, guiding hot air along a predetermined path. When the power devices 110 are operating, the heat generated by them can smoothly flow into the hot aisles 120, facilitating subsequent heat dissipation and effectively improving the heat dissipation efficiency of the power devices 110.

[0079] See also Figure 1 and Figure 2In the embodiment of the present application, both ends of the hot channel 120 along the second direction are respectively provided with an openable and closable channel door 121.

[0080] The provision of the channel door 121 effectively enhances the containment of the hot aisle 120. When closed, the channel door 121 fits snugly against the end of the hot aisle 120, effectively preventing hot air from escaping and ensuring the concentration and efficient circulation of hot air within the hot aisle 120. This improves the efficiency of the thermal management system, helps reduce temperature fluctuations within the equipment room, and provides a more stable operating environment for the power equipment 110.

[0081] The passage door 121 may be a push-pull type or a double-opening type, and a perspective observation window may be provided on the passage door 121 , but this is not limited in this embodiment.

[0082] See also Figure 8 In an embodiment of the present application, the thermal management system of the power room may further include a return air cavity 400 , the cavity wall of the return air cavity 400 is further provided with an inlet 410 and an outlet, the inlet 410 is connected to the heat exhaust port, and the outlet is connected to the heat channel 120 .

[0083] It can be understood that the inlet 410 is connected to the heat exhaust port, and its function is to receive hot air exhausted from the power equipment 110 or other heat sources. After the hot air is initially gathered at the heat exhaust port, it enters the return air chamber 400 through the inlet 410, and the hot air begins to be recycled.

[0084] Furthermore, the outlet is connected to the hot channel 120, and the hot air entering the return air chamber 400 through the inlet 410 is guided to the hot channel 120 through the outlet, and then enters the air-conditioning terminal 210 through the hot channel 120 and the return air port 211 in turn. After cooling treatment at the air-conditioning terminal 210, the closed loop of the entire heat cycle is completed.

[0085] See also Figure 3 When the heat exhaust port of each power device 110 is set at the top, the return air cavity 400 can be set above each integrated power supply device 100.

[0086] See also Figures 8 to 17 In the embodiment of the present application, the top wall of the return air cavity 400 is separated from the top floor 500 of the machine room.

[0087] Such an arrangement provides a smoother channel for air circulation inside the power room, effectively avoiding the problem of excessive heat conduction efficiency caused by direct contact between the return air cavity 400 and the top floor 500, and helps to maintain the stability and controllability of the temperature inside the room.

[0088] In addition, the interval setting ensures that the return air cavity 400 can fully collect the return air from all corners of the machine room, thereby enhancing the uniformity and efficiency of the air flow.

[0089] See also Figures 8 to 17 In the embodiment of the present application, the return air cavity 400 is spaced apart from the integrated power supply device 100 along the third direction, or the return air cavity 400 is arranged adjacent to the integrated power supply device 100 along the third direction.

[0090] Among them, the third direction corresponds to Figure 8 The Z-axis direction.

[0091] On the one hand, the return air chamber 400 can be spaced apart from the integrated power supply device 100 along a third direction. This arrangement provides a wider channel for airflow within the computer room, helping to reduce air flow resistance and improve the efficiency of the thermal management system. Furthermore, this spaced arrangement helps to reduce the impact of noise and vibration generated by the integrated power supply device 100 on the air flow within the return air chamber 400, ensuring the stable operation of the thermal management system.

[0092] Furthermore, the return air chamber 400 is arranged adjacent to the integrated power supply device 100 along the third direction. This arrangement allows for more efficient use of the space within the computer room, improving space efficiency. With this adjacent arrangement, the return air chamber 400 can better receive the hot exhaust air from the integrated power supply device 100, reducing heat loss during air flow and facilitating the rapid collection and centralized processing of hot air.

[0093] See also Figures 6 to 11 In the embodiment of the present application, the air-conditioning terminal 210 is the air-conditioning terminal 210 of the inter-row air conditioner 213 .

[0094] In specific implementation, the air-conditioning terminal 210 of the inter-row air-conditioning 214 can be used and embedded between each power equipment 110. Compared with the related technology of setting the air-conditioning on both sides of the computer room, the air-conditioning terminal 210 provided in the embodiment of the present application shortens the circulation path of the cold air, and realizes efficient and accurate heat management in the computer room by delivering cold air to each power equipment 110 at a close distance.

[0095] In this way, the air conditioning terminals 210 of the inter-row air conditioners 213 can quickly deliver cold air to each power device 110, ensuring a stable environment inside the computer room, reducing the risk of heat accumulation, and improving the operating efficiency and stability of each power device 110.

[0096] Furthermore, the efficient operation of the inter-row air conditioners 213 enhances the system stability of the computer room. By ensuring that each power device 110 always operates within an appropriate temperature range, the inter-row air conditioners 213 reduce the risk of performance degradation, failure, or even shutdown of the power devices 110 due to overheating, thereby improving the reliability and stability of the computer room.

[0097] See also Figures 8 to 11 In the embodiment of the present application, the heat exhaust port is located at the top of the power device 110, and the inlet 410 is opposite to the heat exhaust port.

[0098] It should be noted that locating the heat exhaust vent at the top of the power device 110 takes advantage of the fact that hot air rises. Within the integrated power supply device 100, as the power device 110 operates, a significant amount of heat is generated, which raises the temperature of the surrounding air. Placing the heat exhaust vent at the top of the integrated power supply device 100 more effectively guides this hot air out, improving the thermal management efficiency within the integrated power supply device 100.

[0099] Furthermore, the relative placement of inlet 410 and heat exhaust vents creates a favorable airflow cycle. When cold air enters power equipment 110 through the cold air inlet, it flows through the internal space of power equipment 110, absorbs heat from the equipment 110, and becomes hot air before being discharged through the top heat exhaust vent. This ensures uniform temperature distribution within power equipment 110, improves the heat dissipation efficiency of air conditioning terminal 210, and reduces energy consumption.

[0100] See also Figures 12 to 17 In the embodiment of the present application, the air-conditioning terminal 210 is an air-conditioning terminal 210 of a room-level air conditioner 214 .

[0101] It is understandable that the air-conditioning terminal 210 of the room-level air-conditioning 214 can also be used and embedded between each power equipment 110. Compared with the related technology of setting the air-conditioning on both sides of the computer room, the air-conditioning terminal 210 provided in the embodiment of the present application shortens the circulation path of the cold air, and realizes efficient and accurate heat management in the computer room by delivering cold air to each power equipment 110 at a close distance.

[0102] Thus, the air conditioning terminal 210 of the room-level air conditioner 214 can quickly deliver cold air to each power device 110, ensuring a stable environment inside the computer room, reducing the risk of heat accumulation, and improving the operating efficiency and stability of each power device 110.

[0103] In addition, the room-level air conditioner 214 can ensure that each power device 110 always operates within an appropriate temperature range, reducing the risk of performance degradation, failure or even shutdown of the power device 110 due to overheating, thereby improving the reliability and stability of the power room.

[0104] In the embodiment of the present application, the return air inlet 211 is located at the top of the air conditioning terminal 210 , and the return air inlet 211 is arranged opposite to the outlet 420 .

[0105] It should be noted that the return air vent 211 can be set at the top of the air conditioning terminal 210. In this way, since hot air has the characteristic of rising, the return air vent 211 can more effectively collect the hot air discharged from the power equipment 110.

[0106] Furthermore, the relative arrangement of the return air port 211 and the outlet 420 promotes smooth air circulation. Figures 12 to 17 The air flow in the air conditioning unit (return air vent 211 is not shown in the figure) is controlled. When hot air is discharged through outlet 420, the top return air vent 211 quickly absorbs the hot air. After cooling by the air conditioning terminal 210, the hot air is then cooled and dissipated to the power equipment 110, forming a complete air circulation system. This arrangement improves the cooling efficiency of the air conditioning terminal 210 and avoids local overheating.

[0107] See also Figure 1 and Figure 2 In an embodiment of the present application, the plurality of power devices 110 include an uninterruptible power supply 111 , and the air conditioning terminal 210 is arranged adjacent to the uninterruptible power supply 111 .

[0108] It is understandable that such a setting improves the reliability and stability of the thermal management system of the computer room. The uninterruptible power supply device 111 is used to provide uninterruptible power supply to some equipment that has high requirements for power supply stability, ensuring that important business and data processing are not affected and maintaining service continuity. As a device with a higher heat output in the integrated power supply device 100, the uninterruptible power supply device 111 is set close to the air conditioning terminal 210, which effectively shortens the cooling path and ensures that the power equipment 110 can obtain sufficient cooling in time when running at high load, avoiding performance degradation or equipment damage due to overheating, and further consolidating the stable operation foundation of the thermal management system of the computer room.

[0109] Furthermore, the adjacent placement of the uninterruptible power supply (UPS) 111 and the air conditioning terminal (AC) 210 helps optimize energy utilization. The AC terminal (AC) 210 precisely cools the adjacent power equipment 110, reducing cooling losses during transmission and improving cooling efficiency. Furthermore, the heat generated by the power equipment 110 during operation is more effectively collected and discharged by the AC terminal (AC) 210, forming a highly efficient heat cycle system that helps reduce overall energy consumption.

[0110] Furthermore, within the limited space of the computer room, the power equipment 110 (such as the distribution cabinet 112, the transformer 113, the high-voltage cabinet 114, etc.) is tightly integrated with the uninterruptible power supply device 111 and the air-conditioning terminal 210, thereby avoiding the extra space occupied by long-distance wiring or pipe laying, making the layout of the computer room more compact and reasonable, and improving space utilization.

[0111] See also Figure 1 and Figure 2 In the embodiment of the present application, the uninterruptible power supply 111 is electrically connected to the air-conditioning terminal 210 to supply power to the air-conditioning terminal 210 .

[0112] This ensures the stability and reliability of the power supply to the air conditioning terminal 210. Furthermore, in an environment with unstable power supply, the uninterruptible power supply 111 can switch to the backup power source to continuously power the air conditioning terminal 210, avoiding refrigeration system shutdowns caused by power outages, thereby ensuring a stable environment within the computer room.

[0113] Furthermore, by electrically connecting the uninterruptible power supply 111 to the air conditioning terminal 210, the integration level within the computer room is improved. Compared to related art, where data centers or computer rooms often have multiple independent power supply systems to support different devices and systems, the computer room thermal management system provided in this application, by electrically connecting the uninterruptible power supply 111 to the air conditioning terminal 210, can reduce power transmission links, reduce the complexity of the computer room thermal management system, and improve the stability and efficiency of overall operation.

[0114] See also Figure 4 and Figure 5 In an embodiment of the present application, the integrated power supply device 100 also includes a busbar cavity 140, the busbar cavity 140 defines a busbar chamber 141, the busbar 142 is routed through the busbar chamber 141, and the busbar chamber 141 is located on the upper side of the air-conditioning terminal 210.

[0115] It should be noted that the provision of busbar chamber 141 optimizes the electrical layout and improves space utilization. Within the limited space of the equipment room, busbar chamber 141 provides an independent and secure passage for busbar 142, avoiding cross-interference with other components and ensuring a neat and orderly electrical system. Furthermore, placing busbar chamber 141 above air conditioner terminal 210 rationally utilizes vertical space, making the overall layout more compact and improving the space efficiency of the integrated power supply device 100.

[0116] Furthermore, the busbar chamber 141 provides good protection for the busbar 142. The busbar chamber 141 reduces the potential impact of external factors on the busbar 142 (such as dust, moisture, etc.) through physical isolation, thereby extending the service life of the busbar 142 and reducing maintenance costs.

[0117] In the embodiment of the present application, the air-conditioning terminal 210 is one of an air-cooled air-conditioning, an air-cooled fluorine pump air-conditioning and a chilled water air-conditioning.

[0118] In specific implementation, an air-cooled air conditioner can be selected as the air-conditioning terminal 210. The air-cooled air conditioner uses outdoor air as a cooling medium and transfers heat through a heat exchanger. It does not require additional water sources or cooling towers and other facilities, reducing the complexity and maintenance costs of the power room thermal management system.

[0119] In addition, an air-cooled fluorine pump type air conditioner can also be selected as the air conditioning terminal 210. The air-cooled fluorine pump type air conditioner drives the refrigerant circulation through the fluorine pump, thereby improving the cooling efficiency and energy efficiency ratio of the power room thermal management system.

[0120] It is understandable that a chilled water air conditioner can also be selected as the air conditioning terminal 210. The chilled water air conditioner discharges heat through a chilled water circulation system, has a strong cooling capacity and a high energy efficiency ratio, and can operate continuously and stably in a high temperature environment, providing a stable and reliable cooling environment for the computer room.

[0121] In an embodiment of the present application, the power equipment 110 includes a monitoring module, which is configured to detect the temperature of at least one of the cold channel 130 and the hot channel 120, and control the fan speed of the air conditioning terminal 210 according to the detection result.

[0122] The monitoring module monitors the temperature of at least one of the cold aisle 130 and the hot aisle 120 in real time. Specifically, the monitoring module may include temperature sensors (not shown) installed at the cold air inlet and heat exhaust outlet of each power device 110. The temperature sensors detect the supply air temperature of the air conditioning terminal 210 or the exhaust air temperature of the power device 110 in real time. When using the supply air temperature detection mode, if the supply air temperature is greater than a preset supply air temperature, the monitoring module adjusts the fan speed of the corresponding air conditioning terminal 210 to reduce the supply air temperature. The monitoring module also controls the uninterruptible power supply 111 to enter sleep mode (i.e., temporarily shuts down the uninterruptible power supply 111) to reduce heat generation. If the supply air temperature is less than the preset supply air temperature, the monitoring module adjusts the fan speed of the corresponding air conditioning terminal 210 to increase the supply air temperature. If the supply air temperature is equal to the preset supply air temperature, the current fan speed of the air conditioning terminal 210 is maintained. When using the exhaust temperature detection mode, if the exhaust temperature is greater than a preset temperature, the monitoring module adjusts the fan speed of the corresponding A / C terminal 210 to lower the exhaust temperature. Furthermore, the monitoring module controls the uninterruptible power supply 111 to enter sleep mode (i.e., temporarily shuts down the UPS 111) to reduce heat generation. If the exhaust temperature is less than the preset temperature, the monitoring module adjusts the fan speed of the corresponding A / C terminal 210 to increase the exhaust temperature. If the exhaust temperature is equal to the preset temperature, the current fan speed of the A / C terminal 210 is maintained. With this configuration, if the temperature in the cold aisle 130 or hot aisle 120 is detected to be too high, the monitoring module increases the fan speed of the A / C terminal 210 to increase cooling capacity and thereby lower the ambient temperature. Conversely, if the temperature is too low, the monitoring module decreases the fan speed of the A / C terminal 210 to reduce energy consumption and maintain a suitable ambient temperature.

[0123] Furthermore, in a specific implementation, the monitoring module may also include a load detector installed on each power device 110. The load detector monitors the load of each power device 110 in real time, for example, by monitoring the load of the uninterruptible power supply 111 in real time. When the load of the uninterruptible power supply 111 changes, the monitoring module adjusts the fan speed of the corresponding air conditioning terminal 210 to regulate the ambient temperature and adjusts the operating mode of the uninterruptible power supply 111 to ensure stable operation of the computer room thermal management system. When the load of the uninterruptible power supply 111 remains unchanged, the fan speed of the current air conditioning terminal 210 is maintained. This allows for more efficient control of the ambient temperature within the computer room, avoiding the lag in the air conditioning unit's operation that can occur when adjusting the air conditioning terminal 210 based on temperature sensor detection.

[0124] In an embodiment of the present application, when the air-conditioning terminal 210 is a chilled water type air-conditioning, the air-conditioning terminal 210 includes a refrigeration circuit, and the refrigeration circuit is provided with a water valve for controlling the water flow of the refrigeration circuit. The monitoring module is also configured to control the opening of the water valve according to the detection results.

[0125] That is to say, when using a chilled water air conditioner, if the fan speed is adjusted to the maximum and the cooling capacity still does not meet the requirements, the water valve opening can be adjusted through the monitoring module to adjust the ambient temperature in the computer room to the preset temperature.

[0126] Furthermore, the monitoring module can also be equipped with backup linkage and patrol functions. This means that the AC terminals 210 can be redundantly configured. When the monitoring module detects a failure in an AC terminal 210, it can shut down the failed AC terminal 210 and activate the backup AC terminal 210 to ensure the normal operation of the computer room thermal management system. Furthermore, the monitoring module's patrol function can be configured based on actual conditions, periodically switching to the backup AC terminal 210 to extend the service life of each AC terminal 210 and ensure the operational stability of the computer room thermal management system.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
