Description

Technical Field

[0001] This application relates to the field of equipment cooling technology, and more specifically, to a synergistic cooling system, method, electronic device, and storage medium. Background Technology

[0002] With the continuous growth of power system load, transformers, as core power transmission and transformation equipment, directly affect insulation life and power supply safety through their operating temperature rise, requiring heat dissipation through liquid cooling systems. Transformer cooling subsystems typically employ forced oil circulation or forced water circulation. The heat-carrying liquid flows through the transformer to absorb heat, and then is cooled by radiators before being recycled or discharged.

[0003] The inventors discovered during their research that other heat-generating devices and environmental temperature control devices were located at or near the transformer site. These cooling subsystems operated independently according to their respective preset logic, resulting in a decentralized management of cooling resources within the area. Summary of the Invention

[0014] In one feasible implementation, the detection unit further includes: A third temperature sensor is located in the heat-generating area of ​​the transformer; The method of obtaining the detection value sent by the detection unit further includes: The temperature of the heating area detected by the third temperature sensor is obtained; Based on the detected value, adjusting the opening of the control valve includes: If the liquid temperature at the first outlet is in the second high temperature range and the temperature of the heating area is higher than the preset temperature threshold, then the opening of the first control valve and the second control valve will be set to the maximum and the second alarm state will be entered.

Compared to existing technologies where the transformer cooling circuit discharges liquid directly and each cooling subsystem operates independently, this embodiment can utilize a portion of the liquid discharged from the transformer cooling subsystem to provide cooling for the air conditioning system without adding an additional power source. Simultaneously, the closed-loop regulation matches the diverted flow rate to actual operating conditions, thereby improving the overall energy efficiency of the system.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] With the continuous growth of power system load, transformers, as core power transmission and transformation equipment, directly affect insulation life and power supply safety through their operating temperature rise, requiring heat dissipation through liquid cooling systems. Transformer cooling subsystems typically employ forced oil circulation or forced water circulation. The heat-carrying liquid flows through the transformer to absorb heat, and then is cooled by radiators before being recycled or discharged.

[0030] The inventors discovered during their research that other heat-generating devices and environmental temperature control devices were located at or near the transformer site. These cooling subsystems operated independently according to their respective preset logic, resulting in a decentralized management of cooling resources within the area.

[0031] Based on this, embodiments of this application provide a collaborative cooling system, method, electronic device, and storage medium, which are described below through embodiments.

[0032] To facilitate understanding of this embodiment, a collaborative cooling system disclosed in this application embodiment will first be described in detail. Figure 1 This application provides a schematic diagram showing the connection of multiple cooling subsystems in a collaborative cooling system, as illustrated in an embodiment of the present application. Figure 1 The connection pathways of the transformer cooling subsystem 100 and the air conditioning cooling subsystem 200 included in the coordinated cooling system are described below: The transformer cooling subsystem 100 includes a first inlet 103 and a first outlet 105.

[0033] The liquid is stored in the liquid reservoir 101 and introduced into the first inlet 103 by the water pump 102. The liquid passage between the first inlet 103 and the first outlet 105 forms the first cooling pipe. The liquid is sent to the cooler 104 through the first cooling pipe to complete heat exchange and remove the operating heat of the transformer. The cooled liquid (e.g., water, at a temperature of about 25°C) flows out through the first outlet 105 after heat exchange.

[0034] In practical applications, the liquid can be deionized water, softened water, or industrial circulating water with added preservatives. Cooler 104 can also be an oil-water cooler depending on the site conditions.

[0035] The air conditioning cooling subsystem 200 includes a second inlet 108 and a second outlet 110. A first control valve 106 is provided between the first outlet 105 and the second inlet 108. A water pump 107 is used to draw liquid from the liquid pipe of the first outlet 105. The first control valve 106 controls the flow rate of the liquid diverted from the first outlet 105 to the second inlet 108, and the liquid is cooled by the air conditioner 109 through the second cooling pipe. Then, the liquid flows out through the second outlet 110. The first outlet 105 and the second outlet 110 are connected in parallel to the main pipe 111, so that the two liquids merge and flow out through the main pipe 111, and finally return to the liquid reservoir 101. The passage between 108 and 110 constitutes the second cooling pipe. In some scenarios, the second cooling pipe can directly contact the heat exchanger of the air conditioner 109 for heat exchange, or it can indirectly transfer cooling through an intermediate heat exchange medium.

[0036] In addition, the synergistic cooling system also includes ( Figure 1 (not shown in the image) A detection unit, positioned at a preset location, is communicatively connected to a control unit to detect temperature, pressure, and / or flow rate, and sends the detected values ​​to the control unit.

[0037] The control unit is communicatively connected to the first control valve and is used to adjust the opening degree of the control valve based on the detection value sent by the detection unit; the control valve includes at least the first control valve.

[0038] The control unit communicates with the first control valve via wired or wireless means. During operation, the control unit receives detection values ​​from the detection unit and generates corresponding adjustment commands based on these values ​​to adjust the opening of the first control valve. For example, when the detection unit detects a low transformer outlet water temperature, it indicates a low transformer load or low ambient temperature. In this case, the opening of the first control valve can be reduced to decrease the liquid flow to the air conditioning cooling subsystem. Conversely, when the transformer outlet water temperature is high, the opening of the first control valve can be appropriately increased to allow more liquid to flow to the air conditioning cooling subsystem. In some scenarios, the valve opening can also be adjusted based on the inlet temperature of the air conditioning cooling subsystem or the indoor ambient temperature. Furthermore, the control unit can employ strategies such as proportional control, PID control, or fuzzy control, and is not limited to a specific adjustment algorithm. Through these methods, the diverted flow rate can be matched to the actual operating conditions.

[0039] Understandably, the number of control valves is not limited to one. In scenarios requiring multiple flow branches or more precise adjustments to the air conditioning cooling subsystem, a second control valve or more valves may be added. The specific installation location of the detection unit can be determined according to the actual operating conditions. For example, it can be installed at the first outlet to monitor the outlet water temperature, or at the second inlet to monitor the liquid flow rate entering the air conditioning system, or multiple detection points can be arranged simultaneously to obtain more comprehensive operating data.

[0040] This application provides a collaborative cooling system, method, electronic device, and storage medium. The collaborative cooling system includes a transformer cooling subsystem and an air conditioning cooling subsystem. A first control valve is provided between the first outlet of the transformer cooling subsystem and the second inlet of the air conditioning cooling subsystem, allowing a portion of the liquid from the outlet of the transformer cooling subsystem to flow into the air conditioning cooling subsystem. After cooling the air conditioner via a second cooling pipe, the liquid merges with the liquid from the first outlet and is discharged through a main pipe. Simultaneously, a detection unit located at a preset position detects temperature, pressure, and / or flow rate in real time and sends the data to a control unit. The control unit adjusts the opening of the first control valve based on the detected values.

[0041] This collaborative cooling system, through its design of connecting the first and second outlets in parallel to the main pipeline, allows the transformer cooling subsystem and the air conditioning cooling subsystem to share a common discharge channel. Furthermore, utilizing a closed-loop regulation mechanism with a first control valve and a detection unit, the system can dynamically adjust the liquid flow rate diverted to the air conditioning cooling subsystem based on real-time detection values. Compared to existing technologies where the transformer cooling circuit discharges liquid directly and each cooling subsystem operates independently, this embodiment can utilize a portion of the liquid discharged from the transformer cooling subsystem to provide cooling for the air conditioning system without adding an additional power source. Simultaneously, the closed-loop regulation matches the diverted flow rate to actual operating conditions, thereby improving the overall energy efficiency of the system.

[0042] In one feasible implementation, the detection unit includes: The first temperature sensor is located at the second inlet 108.

[0043] The control unit is used to adjust the opening of the control valve based on the detection value sent by the detection unit, for the following purposes: If the first temperature sensor detects that the liquid temperature at the second inlet is not within the preset temperature range, the opening degree of the first control valve is increased.

[0044] A suitable temperature range is preset (assumed to be [22℃, 28℃]). When the liquid temperature at the second inlet falls within this preset temperature range, it is considered that the liquid temperature currently diverted to the air conditioning side can meet the air conditioning heat dissipation requirements. At this time, the opening of the first control valve remains unchanged, the flow rate of the air conditioning branch is maintained near the rated flow rate corresponding to the current opening, the main transformer water supply pump operates stably according to the main transformer cooling requirements, and the whole scheme is in a better state of coordinated utilization of cooling capacity.

[0045] When the liquid temperature at the second inlet 108 deviates from this temperature range, the opening of the first control valve is increased. This involves two scenarios: If the temperature is too low, it means that the cooling capacity on the transformer outlet side is sufficient. In this case, increasing the shunt flow rate can allow more low-temperature liquid to enter the air conditioning cooling subsystem, making full use of this cooling capacity to improve the heat exchange efficiency of the air conditioning.

[0046] If the temperature is too high, it means that the liquid carries a lot of heat, and its effect on cooling the air conditioner directly is limited. In this case, increase the opening to introduce more liquid, and enhance the heat dissipation capacity of the air conditioner side by increasing the flow rate to compensate for the insufficient heat exchange caused by the high temperature.

[0047] It is important to note that the increase in flow rate should be controlled within the design capacity of the pipeline and water pump to ensure the safe operation of the equipment. At the same time, a warning signal can be issued when the temperature remains high.

[0048] In practical applications, this temperature range can be set according to the specific model and operating requirements of the air conditioning equipment.

[0049] In addition, some alternative solutions involve reducing the opening degree when the temperature is too low. This prevents excessive cryogenic liquid from entering the air conditioning side, which could lead to low condensing pressure or a protective shutdown of the unit, thus improving the stability of the air conditioning equipment. The specific adjustment method used can be flexibly determined based on the actual operating conditions and the permissible operating range of the air conditioning unit.

[0050] In one feasible implementation, the detection unit includes: The second temperature sensor is located at the first outlet 105 and is used to detect the liquid temperature at the first outlet 105 of the transformer cooling subsystem 100.

[0051] like Figure 2 As shown, the transformer cooling subsystem 100 further includes a second control valve 112 disposed at the first inlet 103. The second control valve 112 is communicatively connected to the control unit, and the control valve further includes the second control valve 112.

[0052] The control unit is used to adjust the opening of the control valve based on the detection value sent by the detection unit, for the following purposes: If the second temperature sensor detects that the liquid temperature at the first outlet 105 is in the first high temperature range, the opening degree of the first control valve 106 and the second control valve 112 is increased, and the system enters the first alert state.

[0053] Increasing the opening of the second control valve 112 increases the total liquid flow rate introduced into the transformer cooling subsystem 100 from the liquid reservoir 101, thereby enhancing the cooling effect on the transformer. Increasing the opening of the first control valve 106 diverts more liquid to the air conditioning cooling subsystem 200, avoiding resource waste due to excessive flow in the main circuit after the total flow rate increases. It also helps to utilize the heat exchange capacity of the air conditioning side to assist in heat dissipation. The first warning state is a suggestive state used to indicate that the current operating parameters of the collaborative cooling system have exceeded the normal range. It can trigger corresponding audible and visual alarms or remote notifications so that maintenance personnel can pay attention, such as prompting them to check the transformer load and the corresponding cooling system.

[0054] In practical applications, the specific value of the first high-temperature range can be set according to the transformer's rated parameters and operating conditions. In some scenarios, the first high-temperature range can be set slightly higher than the upper limit of the transformer's normal operating temperature range. For example, when the normal outlet water temperature of the transformer is 25℃ to 28℃, the first high-temperature range can be set to 28℃ to 30℃. Of course, the specific value of this range will vary for different transformer models or under different environmental conditions, and should not be construed as the only limitation of this solution.

[0055] In one feasible implementation, the detection unit further includes: The third temperature sensor is located in the heat-generating area of ​​the transformer.

[0056] The control unit is configured to adjust the opening of the control valve based on the detection value sent by the detection unit, and is also configured to: If the second temperature sensor detects that the liquid temperature at the first outlet 105 is in the second high temperature range, and the third temperature sensor detects that the temperature of the heating area is higher than a preset temperature threshold, then the opening of the first control valve 106 and the second control valve 112 is set to the maximum, and the system enters the second alert state.

[0057] After the duration of entering the second alert state reaches the preset duration, the detection values ​​of the second temperature sensor and the third temperature sensor are reacquired. If the conditions are still met: the liquid temperature of the first outlet 105 is in the second high temperature range and the temperature of the heating area is higher than the preset temperature threshold, then the second control valve 106 is closed to stop cooling the air conditioning cooling subsystem.

[0058] That is, a second high-temperature range is preset, as well as a temperature threshold for the heat-generating area. When the second temperature sensor detects that the liquid temperature at the first outlet 105 is within this second high-temperature range, and the third temperature sensor detects that the temperature of the heat-generating area is higher than the preset threshold, it indicates that the transformer's own heat dissipation is already under a high load, and the surrounding ambient temperature is also high, indicating a severe overall thermal situation. At this time, the control unit adjusts the opening of both the first control valve 106 and the second control valve 112 to their maximum and enters the second alarm state.

[0059] Adjusting the first control valve 106 to its maximum allows as much liquid as possible to be diverted to the air conditioning cooling subsystem 200, utilizing the heat exchange capacity of the air conditioning side to assist in heat dissipation. Adjusting the second control valve 112 to its maximum increases the total liquid flow rate introduced into the transformer cooling subsystem 100 from the source, thereby enhancing the cooling effect on the transformer body. The second warning state is an emergency alert state, indicating that the current operating parameters have reached a relatively dangerous boundary, requiring close monitoring and possible further countermeasures.

[0060] After entering the second alert state and maintaining it for a preset duration, the control unit re-acquires the detection values ​​from the second and third temperature sensors to determine whether the liquid temperature at the first outlet 105 is still within the second high-temperature range and whether the temperature of the heat-generating area is still higher than the preset threshold. If both conditions are still met simultaneously, it indicates that simply increasing the flow rate is insufficient to effectively suppress the temperature rise. At this point, the control unit closes the second control valve 112 to stop supplying liquid to the air conditioning cooling subsystem.

[0061] After closing the second control valve 112, the liquid flow originally diverted to the air conditioning side is entirely used in the main circuit, ensuring that the transformer cooling subsystem receives the maximum available flow, thus prioritizing the cooling needs of the main transformer. Simultaneously, this action is accompanied by stopping the liquid supply to the air conditioning side, meaning the air conditioning equipment will no longer rely on this liquid for cooling. During this process, the ventilation volume in the transformer room can also be increased to help lower the ambient temperature, and if necessary, the transformer load can be limited, and a remote alarm can be issued to notify maintenance personnel.

[0062] It should be noted that the value of the second high-temperature range is usually higher than that of the first high-temperature range, representing a more severe overheating situation. For example, it can be set to above 30°C, and the preset temperature threshold can be set to 36°C (so that it can identify when the temperature of the transformer's heating area exceeds this temperature threshold). The preset duration can be set according to actual engineering experience, for example, it can be set to 30 seconds to 2 minutes to avoid malfunctions caused by instantaneous fluctuations. In specific implementation, the above temperature threshold, high-temperature range, and preset duration can all be flexibly adjusted according to the transformer's rated parameters, installation environment, and operating requirements.

[0063] In one feasible implementation, the detection unit includes: Multiple flow sensors are respectively installed in the first cooling pipe and the second cooling pipe to detect the flow rate in the corresponding cooling pipe.

[0064] The transformer cooling subsystem also includes a second control valve (in conjunction with) located at the first inlet. Figure 2 (Understood, not elaborated here); the second control valve is communicatively connected to the control unit; the control valve also includes the second control valve.

[0065] The control unit is used to adjust the opening of the control valve based on the detection value sent by the detection unit, for the following purposes: For any cooling pipe, when the error between the actual flow rate detected by the flow sensor in the cooling pipe and the preset rated flow rate for the cooling pipe exceeds the preset error value, the opening of the control valve corresponding to the cooling pipe is adjusted.

[0066] Based on the flow rate value detected by the flow sensor, the control unit makes the following adjustments: For any cooling pipe, when the deviation between the actual flow rate detected by the flow sensor in that pipe and the preset rated flow rate of that pipe exceeds a preset error value, the control unit adjusts the opening of the control valve corresponding to that pipe. For example, when the actual flow rate in the first cooling pipe deviates significantly from its rated flow rate, the total amount of liquid introduced into the transformer cooling section can be changed by adjusting the second control valve 112; when the actual flow rate in the second cooling pipe deviates significantly from its rated flow rate, the amount of liquid diverted to the air conditioning cooling section can be changed by adjusting the first control valve 106. The adjustment direction depends on whether the actual flow rate is too high or too low; if it is too low, the opening is increased; if it is too high, the opening is decreased, so that the actual flow rate returns to near the rated value. For example, when the preset error value is ±15% of the rated flow rate, if the actual flow rate exceeds this range, it is determined to be an abnormal flow rate and corresponding adjustments are made.

[0067] By using the above methods, the actual operating flow rate of each cooling pipe can be matched with the preset requirements, avoiding the impact on the cooling effect due to excessive flow deviation.

[0068] It should be noted that the preset error value can be set according to the pipe diameter, liquid properties, and the equipment's requirements for flow accuracy. For example, it can be set to ±5%, ±10%, or ±15% of the rated flow. Different cooling pipes can have the same rated flow, or different values ​​can be set according to the needs of the equipment they serve. The specific type of flow sensor can be an electromagnetic flow meter, ultrasonic flow meter, or turbine flow meter, etc., and the specific model can be selected according to the actual operating conditions.

[0069] In one feasible implementation, the detection unit includes: A pressure sensor is installed in the second cooling pipe to detect the pressure inside the second cooling pipe.

[0070] The control unit is used to adjust the opening of the control valve based on the detection value sent by the detection unit, for the following purposes: When the pressure sensor detects that the pressure in the second cooling pipe is not within the preset pressure range, it controls the first control valve to close.

[0071] A preset pressure range is established. When the pressure sensor detects that the pressure in the second cooling pipe is outside this range, the control unit closes the first control valve 106. A pressure deviation from the preset range in the second cooling pipe may indicate a leak, blockage, or other abnormal condition. For example, if the pressure is too high (e.g., exceeding 0.6 MPa), it may indicate pipe blockage, filter clogging, or system overpressure. Closing the first control valve 106 in this case cuts off the liquid supply to the air conditioning cooling section, stops the branch water pump, and issues a high-pressure alarm. If the pressure is too low (e.g., below 0.15 MPa), it may indicate pipe leakage, system underpressure, or a risk of cavitation. Closing the first control valve 106 and stopping the branch water pump in this case prevents equipment damage and issues a low-pressure alarm. Through this method, the air conditioning cooling branch can be automatically isolated when pressure is abnormal, preventing the abnormal condition from escalating or causing further damage to the equipment, while ensuring the safe operation of the transformer cooling section.

[0072] It should be noted that the specific pressure range should be determined based on the pressure resistance rating of the pipe material used in the second cooling pipe, the pressure-bearing capacity of the air conditioning cooling section, and the normal operating pressure of the system. The aforementioned 0.6MPa and 0.15MPa are merely exemplary values; in practical applications, corresponding upper and lower limits can be set according to specific operating conditions. Furthermore, when the pressure deviates from the preset range, in addition to closing the first control valve 106, an alarm signal can also be issued simultaneously to prompt maintenance personnel to inspect the second cooling pipe.

[0073] In another feasible implementation, the detection unit also includes a temperature sensor installed at the water inlet of the transformer cooling section and a flow sensor installed in the main circuit, for detecting the transformer inlet water temperature (temperature of the first inlet) and the flow rate in the first cooling pipe of the transformer cooling subsystem. When both exceed the preset normal range, measures such as limiting the transformer load and issuing a remote alarm can be taken to ensure the safe operation of the transformer.

[0074] Figure 3 This paper shows a schematic diagram of the arrangement of a collaborative cooling system provided in an embodiment of the present application. Figure 3 The serial number in Figures 1-2 The corresponding components pointed to by each serial number are not described here.

[0075] Based on the same technical concept, this application also provides a synergistic cooling method applied to a control unit of a synergistic cooling system, the synergistic cooling system comprising: The transformer cooling subsystem includes a first inlet and a first outlet, for introducing liquid from the first inlet, cooling the transformer through the first cooling pipe, and then flowing out through the first outlet.

[0076] An air conditioning cooling subsystem includes a second inlet and a second outlet; a first control valve is provided between the first outlet and the second inlet to control the flow rate of liquid diverted from the first outlet to the second inlet, and to cool the air conditioner through a second cooling pipe, and then flow out through the second outlet. The first outlet and the second outlet are connected in parallel to a main pipe so that the liquid from the first outlet and the second outlet flows out through the main pipe together.

[0077] A detection unit, located at a preset position, is communicatively connected to the control unit and is used to detect temperature, pressure, and / or flow rate, and transmit the detected values ​​to the control unit. The control unit is also communicatively connected to the first control valve.

[0078] The hardware structure involved in this method (including the transformer cooling subsystem, the air conditioning cooling subsystem, the first control valve located between the first outlet and the second inlet, and the detection unit arranged at a preset position, etc.) can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0079] like Figure 4 As shown, the method includes: Step 401: Obtain the detection value sent by the detection unit.

[0080] The detected values ​​include parameters such as temperature, pressure, and / or flow rate, depending on the type and location of the sensors deployed. The detection unit can acquire these parameters in real time or periodically and transmit them to the control unit via wired or wireless means.

[0081] Step 402: Based on the detected value, adjust the opening of the control valve; the control valve includes at least the first control valve.

[0082] The control unit generates corresponding control commands according to the received detection values ​​and preset adjustment logic to adjust the opening degree of the control valve. The control valve here includes at least a first control valve located between the first outlet and the second inlet, used to control the liquid flow rate diverted from the transformer cooling subsystem to the air conditioning cooling subsystem. In some embodiments, the control valve may further include a second control valve located at the inlet of the transformer cooling subsystem, used to adjust the total liquid flow rate introduced into the transformer cooling subsystem.

[0083] Specific adjustment strategies can be found in the adjustment logic corresponding to the detection values ​​of the aforementioned sensors. For example, adjusting the valve opening based on the detection value of the temperature sensor, making the actual flow rate approach the rated flow rate based on the detection value of the flow sensor, or closing the valve when the pressure is abnormal based on the detection value of the pressure sensor. These will not be elaborated on here.

[0084] In one feasible implementation, the detection unit includes: The first temperature sensor is located at the second inlet.

[0085] Obtaining the detection value sent by the detection unit includes: The liquid temperature detected by the first temperature sensor at the second inlet is obtained.

[0086] Adjusting the opening of the control valve based on the detected value includes: If the liquid temperature is not within the preset temperature range, the opening degree of the first control valve is increased.

[0087] In one feasible implementation, the detection unit includes: A second temperature sensor is located at the first outlet.

[0088] The transformer cooling subsystem further includes a second control valve disposed at the first inlet; the second control valve is communicatively connected to the control unit, and the control valve further includes the second control valve.

[0089] Obtaining the detection value sent by the detection unit includes: The liquid temperature detected by the second temperature sensor at the first outlet is obtained.

[0090] Based on the detected value, adjusting the opening of the control valve includes: If the second temperature sensor detects that the liquid temperature at the first outlet is in the first high temperature range, the opening degree of the first control valve and the second control valve is increased, and the system enters the first alarm state.

[0091] In one feasible implementation, the detection unit further includes: The third temperature sensor is located in the heat-generating area of ​​the transformer.

[0092] The method of obtaining the detection value sent by the detection unit further includes: The temperature of the heating area detected by the third temperature sensor is obtained.

[0093] Based on the detected value, adjusting the opening of the control valve includes: If the liquid temperature at the first outlet is in the second high temperature range and the temperature of the heating area is higher than the preset temperature threshold, then the opening degree of the first control valve and the second control valve will be set to the maximum, and the second alarm state will be entered.

[0094] After the second alert state has been in effect for a preset duration, the detection values ​​of the second temperature sensor and the third temperature sensor are reacquired. If the conditions are still met: the liquid temperature at the first outlet is in the second high temperature range and the temperature of the heating area is higher than the preset temperature threshold, then the second control valve is closed to stop cooling the air conditioning cooling subsystem.

[0095] In one feasible implementation, the detection unit includes: Multiple flow sensors are respectively installed in the first cooling pipe and the second cooling pipe to detect the flow rate in the corresponding cooling pipe.

[0096] The transformer cooling subsystem further includes a second control valve disposed at the first inlet; the second control valve is communicatively connected to the control unit; the control valve further includes the second control valve.

[0097] Obtaining the detection value sent by the detection unit includes: Obtain the actual flow rate of each cooling pipe detected by the flow sensor.

[0098] Adjusting the opening of the control valve based on the detected value includes: For any cooling pipe, when the error between the actual flow rate detected by the flow sensor in the cooling pipe and the preset rated flow rate for the cooling pipe exceeds the preset error value, the opening of the control valve corresponding to the cooling pipe is adjusted.

[0099] In one feasible implementation, the detection unit includes: A pressure sensor is installed in the second cooling pipe to detect the pressure inside the second cooling pipe.

[0100] Obtaining the detection value sent by the detection unit includes: The pressure inside the second cooling pipe detected by the pressure sensor is obtained.

[0101] Adjusting the opening of the control valve based on the detected value includes: When the pressure in the second cooling pipe is not within the preset pressure range, the first control valve is closed.

[0102] This application provides a collaborative cooling system, method, electronic device, and storage medium. The collaborative cooling system includes a transformer cooling subsystem and an air conditioning cooling subsystem. A first control valve is provided between the first outlet of the transformer cooling subsystem and the second inlet of the air conditioning cooling subsystem, allowing a portion of the liquid from the outlet of the transformer cooling subsystem to flow into the air conditioning cooling subsystem. After cooling the air conditioner via a second cooling pipe, the liquid merges with the liquid from the first outlet and is discharged through a main pipe. Simultaneously, a detection unit located at a preset position detects temperature, pressure, and / or flow rate in real time and sends the data to a control unit. The control unit adjusts the opening of the first control valve based on the detected values.

[0103] This collaborative cooling system, through its design of connecting the first and second outlets in parallel to the main pipeline, allows the transformer cooling subsystem and the air conditioning cooling subsystem to share a common discharge channel. Furthermore, utilizing a closed-loop regulation mechanism with a first control valve and a detection unit, the system can dynamically adjust the liquid flow rate diverted to the air conditioning cooling subsystem based on real-time detection values. Compared to existing technologies where the transformer cooling circuit discharges liquid directly and each cooling subsystem operates independently, this embodiment can utilize a portion of the liquid discharged from the transformer cooling subsystem to provide cooling for the air conditioning system without adding an additional power source. Simultaneously, the closed-loop regulation matches the diverted flow rate to actual operating conditions, thereby improving the overall energy efficiency of the system.
