[0002] A heat dissipation system uses liquid as a cooling medium to dissipate heat from heat sources in a building. Monitoring the heat dissipation system is crucial to ensuring effective heat dissipation.

[0003] In related technologies, the location of a liquid leak in the cooling system is determined based on the temperature detected by point sensors installed in the system. Afterwards, maintenance personnel shut down the cooling system, repair the leak, and then restart the system.

[0004] However, in the above process, there are blind spots in temperature detection by point sensors. Furthermore, after a liquid leak occurs, the heat dissipation system needs to be shut down and then restarted, resulting in poor heat dissipation during the shutdown period. Summary of the Invention

[0008] Based on the trend of temperature change over time, the flow rate of the fluid in the heat dissipation system, and the physical properties of the pipe, the heat transfer law in the heat dissipation system is determined.

[0009] If, based on the heat transfer pattern in the heat dissipation system, it is determined that the rate of change of the temperature gradient at the target location in the heat dissipation system is greater than a preset temperature gradient change rate threshold, then the target location is determined as a leakage point.

[0010] The valve of the fluid function unit where the leak point is located in the heat dissipation system is closed, and the corresponding target backup fluid function unit is started.

[0011] According to another aspect of the present invention, a control device for a heat dissipation system is provided, the device comprising:

[0012] An acquisition module is used to acquire the temperature detected by the temperature-sensing optical fiber in real time; wherein, the temperature-sensing optical fiber is used to detect the temperature of the pipes and equipment in the heat dissipation system.

[0013] The first determining module is used to determine the heat transfer law in the heat dissipation system based on the trend of temperature change over time, the flow rate of the fluid in the heat dissipation system, and the physical properties of the pipe.

[0014] The second determining module is used to determine the target location as a leakage point if, based on the heat transfer law in the heat dissipation system, the rate of change of the temperature gradient at the target location in the heat dissipation system is greater than a preset temperature gradient rate of change threshold.

[0015] The shutdown module is used to control the valve of the fluid function unit where the leak point is located in the heat dissipation system to close, and to control the corresponding target backup fluid function unit to start.

[0021] According to another aspect of the present invention, a computer program product is provided, comprising a computer program that, when executed by a processor, implements the control method of the heat dissipation system described in any embodiment of the present invention.

[0022] The technical solution of this invention includes: acquiring the temperature detected by a temperature-sensing optical fiber in real time, wherein the temperature-sensing optical fiber is used to detect the temperature of pipes and equipment in the heat dissipation system; determining the heat transfer law in the heat dissipation system based on the trend of temperature change over time, the flow rate of the fluid in the heat dissipation system, and the physical properties of the pipes; if, based on the heat transfer law in the heat dissipation system, the rate of change of the temperature gradient at a target location in the heat dissipation system is determined to be greater than a preset temperature gradient rate of change threshold, then the target location is determined as a leak point; controlling the valve of the fluid functional unit where the leak point is located in the heat dissipation system to close, and controlling the corresponding target backup fluid functional unit to start. It has the following technical advantages: First, it enables continuous and blind-spot-free temperature detection of the entire heat dissipation system through temperature-sensing optical fibers.

[0034] Figure 1 This is a flowchart illustrating a control method for a heat dissipation system according to an embodiment of the present invention. This embodiment is applicable to scenarios requiring monitoring and self-healing of heat dissipation systems. The method can be executed by a control device for the heat dissipation system, which can be implemented in hardware and / or software. This control device can be configured in electronic devices, such as computer equipment or servers. Figure 1As shown, the method includes the following steps 101 to 104.

[0035] Step 101: Acquire the temperature detected by the temperature-sensing fiber optic cable in real time.

[0036] Among them, the temperature-sensing optical fiber is used to detect the temperature of pipes and equipment in the heat dissipation system.

[0037] The heat dissipation system in this embodiment can be used to dissipate heat from a heat source. For example, the heat source in this embodiment can be a computer facility such as a data center. The data center in this embodiment can be a data center in the financial sector. The heat dissipation system in this embodiment can be a liquid cooling system and / or an air conditioning water system.

[0038] Figure 2 This is a schematic diagram of a heat dissipation system provided in an embodiment of the present invention. Figure 2 As shown, the heat dissipation system includes a heat exchanger. One side of the heat exchanger is a chilled water circuit, and the other side is a cooling water circuit. The chilled water circuit removes heat from the heat source. The cooling water circuit carries the heat from the chilled water circuit to the outside and releases it into the atmosphere through a cooling tower. The heat exchanger physically isolates but functionally connects the chilled water circuit and the cooling water circuit, efficiently transferring heat from the chilled water circuit to the cooling water circuit without mixing the two types of water. Pumps, valves, and other auxiliary equipment are installed in both the chilled water circuit and the cooling water circuit.

[0039] In this embodiment, the temperature of the heat dissipation system is monitored using a temperature-sensing optical fiber. The temperature-sensing optical fiber in this embodiment can employ distributed optical fiber temperature measurement technology to detect the temperature at its location. Before this method is implemented, a temperature-sensing optical fiber network needs to be deployed in the heat dissipation system: corrosion-resistant temperature-sensing optical fibers are spirally wound along the outer wall of the pipes in the heat dissipation system, ensuring a tight fit with the pipe wall and covering the entire length of the pipes (including key nodes such as water pumps and valves). After deploying the optical fiber network, the temperature-sensing optical fiber can collect the temperature of the pipes and equipment in the heat dissipation system in real time and send it to the control equipment of the heat dissipation system. Furthermore, the temperature-sensing optical fiber enables full-area temperature field sensing of the heat dissipation system, achieving continuous monitoring of temperature distribution without blind spots.

[0040] In this embodiment, the spatial detection accuracy of the fiber optic network is less than or equal to 1 meter, for example, the spatial detection accuracy is 0.5 meters, and the temperature error is ±0.5 degrees Celsius (°C).

[0041] In this embodiment, by incorporating temperature-sensing optical fibers, the overall sensing capability of the heat dissipation system is enhanced. A distributed optical fiber network enables continuous, blind-spot-free monitoring of the temperature field within the pipes of the heat dissipation system, overcoming the dependence of traditional point sensors on local nodes and simultaneously capturing temperature gradient changes and abnormal hotspot distribution along the entire pipe. Furthermore, the passive and electromagnetic interference-resistant optical fiber network can operate stably for extended periods in high-pressure, high-humidity, and corrosive environments, avoiding the failure risk of traditional electronic sensors due to environmental degradation, thus improving the reliability and anti-interference capability of the heat dissipation system control process.

[0042] Step 102: Determine the heat transfer pattern in the heat dissipation system based on the temperature change trend over time, the flow rate of the fluid in the heat dissipation system, and the physical properties of the pipes.

[0043] After obtaining the temperature detected by the temperature-sensing fiber optic cable, in order to accurately detect faults, data from two dimensions—the flow rate of the fluid in the heat dissipation system and the physical properties of the pipes—can be combined to comprehensively determine the heat transfer pattern in the heat dissipation system.

[0044] In this embodiment, the heat transfer law in the heat dissipation system is used to characterize the heat distribution law in the heat dissipation system, and the determination process of this distribution law takes into account the fluid velocity and the physical properties of the pipes. In this embodiment, the fluid velocity can be obtained by the water pump in the heat dissipation system. The physical properties of the pipes in this embodiment refer to the physical layout and diameter of the pipes, which can be obtained from the design data of the heat dissipation system.

[0045] In one implementation, step 102 can be implemented by inputting the temperature change trend over time, the flow rate of the fluid in the heat dissipation system, and the physical properties of the pipe into a pre-trained heat transfer law determination model, and determining the heat transfer law of the model output in the heat dissipation system.

[0046] In another implementation, step 102 may include: establishing a dynamic model of the temperature distribution of the heat dissipation system over time based on the trend of temperature change over time; and determining the heat transfer law in the heat dissipation system based on the dynamic model, the flow rate of the fluid in the heat dissipation system, and the physical properties of the pipes.

[0047] In this embodiment, the dynamic model is a three-dimensional model used to characterize the temperature change over time as detected by the temperature-sensing optical fiber at different locations. It can be determined based on the trend of temperature change over time as determined by the temperature detected by the temperature-sensing optical fiber. Optionally, a dynamic model of the temperature distribution of the heat dissipation system over time can be established using a fluid dynamics modeling algorithm.

[0048] In this implementation, a dynamic model is first established based on the temperature change over time to determine the heat transfer law in the heat dissipation system. Then, the transfer law is determined based on the dynamic model, fluid velocity, and physical properties of the pipe. This improves the accuracy of the determined transfer law and increases computational efficiency.

[0049] In this step, multi-dimensional data fusion is used to combine multi-source data such as temperature field, flow rate, and physical properties of pipes to construct the heat transfer law in the heat dissipation system, providing more comprehensive data support for the detection of heat dissipation system faults.

[0050] The control method for the heat dissipation system provided in this embodiment achieves full-dimensional perception of the pipe temperature field through fiber optic temperature measurement technology. Combined with fluid simulation, it breaks through the technical bottleneck of "local monitoring-static control" in traditional heat dissipation systems and constructs a dynamic optimization model that coordinates multiple parameters such as "temperature field-flow rate-physical properties of the pipe".

[0051] Step 103: If, based on the heat transfer law in the heat dissipation system, the rate of change of the temperature gradient at the target location in the heat dissipation system is determined to be greater than the preset temperature gradient rate of change threshold, then the target location is determined as the leakage point.

[0052] After determining the heat transfer pattern in the heat dissipation system, the rate of change of the temperature gradient at various locations within the system can be determined based on this pattern. In this embodiment, the temperature gradient refers to the direction and rate of change of the most drastic temperature change at a given point in space. It is a vector pointing in the direction of the fastest temperature increase, characterizing the steepness of the temperature field. This embodiment determines the rate of change of the temperature gradient, i.e., how quickly the temperature gradient at a given point changes over time.

[0053] A properly functioning, leak-free cooling system achieves a stable or predictable dynamic thermal equilibrium. This means that while the temperature distribution and temperature gradient at different points in the system may vary, they are typically continuous, smooth, and conform to design expectations (e.g., changing regularly along the flow direction). A leak event instantly disrupts this equilibrium, causing anomalies in the temperature field, specifically manifested as a sharp increase in the rate of change of the temperature gradient. In this embodiment, if the rate of change of the temperature gradient at a certain location exceeds a preset threshold, it indicates that a leak has occurred at that location.

[0054] Step 104: Close the valve of the fluid function unit where the leak point is located in the heat dissipation system, and start the corresponding target backup fluid function unit.

[0055] In this embodiment, to avoid the problem of poor heat dissipation due to the cooling system stopping due to a leakage event, after the leakage point is determined, the valve of the fluid function unit where the leakage point is located can be automatically controlled to close, thereby automatically isolating the fault area and controlling the corresponding target backup fluid function unit to start, thus achieving fault self-healing.

[0056] In one implementation, the pipes in the heat dissipation system are equipped with corresponding backup pipes, and the equipment in the heat dissipation system is equipped with corresponding backup equipment. In this implementation, the target backup fluid function unit corresponding to the fluid function unit where the leak point is located is activated.

[0057] In another implementation, in order to improve the flexibility of the fault self-healing process, before controlling the corresponding target backup fluid functional unit to start in step 104, the method provided in this embodiment further includes the following steps: according to the location and function of the fluid functional unit where the leak point is located, control the backup pipes and backup equipment in the heat dissipation system to form the target backup fluid functional unit.

[0058] In this implementation, the heat dissipation system is equipped with general-purpose backup pipes and backup equipment. In the event of a leak, the backup pipes and equipment can be flexibly combined according to the location and function of the fluid functional unit where the leak point is located to form a target backup fluid functional unit capable of performing the function of the fluid functional unit at the leak point. This implementation achieves flexible fault self-healing by controlling the combination of backup pipes and backup equipment to form a target backup fluid functional unit based on the location and function of the fluid functional unit where the leak point is located.

[0059] Figure 3 This is a schematic diagram of another heat dissipation system provided in an embodiment of the present invention. Figure 3 As shown, after the leak point 30 is identified, the valve of the fluid function unit where the leak point 30 is located in the heat dissipation system is closed, and the corresponding target backup fluid function unit 31 is started.

[0060] Optionally, to improve operational efficiency, after closing the valve of the fluid functional unit where the leak point in the heat dissipation system is located in step 104, the method provided in this embodiment further includes the following steps: generating a maintenance work order based on the target location, the time of determining the leak point, and the rate of change of the temperature gradient at the target location; and pushing the maintenance work order to the terminal equipment of the maintenance personnel. Maintenance personnel can then promptly perform maintenance at the target location based on the maintenance work order, thereby improving operational efficiency.

[0061] Furthermore, the method provided in this embodiment also includes the following steps: if, based on the heat transfer law in the heat dissipation system, it is determined that the temperature difference between the pipes on both sides of the heat exchanger does not meet the preset first temperature difference range, then it is determined that the heat exchanger is scaled; if, based on the heat transfer law in the heat dissipation system, it is determined that the temperature difference between the water supply pipe and the return water pipe does not meet the preset second temperature difference range, then it is determined that the water pump is faulty.

[0062] If the temperature difference between the pipes on both sides of the heat exchanger does not meet the preset first temperature difference range, it indicates that the heat exchanger's heat exchange efficiency has decreased, which is generally caused by scaling in the heat exchanger. For example, the first temperature difference range can be 5 to 7°C.

[0063] In this embodiment, both the chilled water circuit and the cooling water circuit are equipped with supply and return water pipes. For the chilled water circuit, if, based on the heat transfer characteristics in the heat dissipation system, the temperature difference between the supply and return water pipes does not meet a preset second temperature difference range, then the water pump in the chilled water circuit is determined to be faulty. For the cooling water circuit, if, based on the heat transfer characteristics in the heat dissipation system, the temperature difference between the supply and return water pipes does not meet a preset second temperature difference range, then the water pump in the cooling water circuit is determined to be faulty. The second temperature difference range corresponding to the chilled water circuit and the second temperature difference range corresponding to the cooling water circuit can be the same or different. For example, the second temperature difference range can be 6 to 8°C.

[0064] In this implementation, by considering temperature, fluid velocity, and the physical properties of the pipes in determining the heat transfer pattern in the heat dissipation system, multi-dimensional data fusion is achieved, thus improving the accuracy of identifying heat exchanger and water pump faults. Furthermore, in this embodiment, temperature gradient analysis and pattern recognition are used to detect potential faults such as pipe leaks and heat exchanger scaling in advance, avoiding energy efficiency degradation caused by equipment deterioration in the heat dissipation system and achieving early warning of anomalies. Simultaneously, this control method automatically isolates the fault area and activates redundant equipment after a leak event is triggered, minimizing downtime and ensuring continuous operation of heat sources such as data centers, thereby improving the reliability and safety of the heat dissipation system.

[0065] The control method for the heat dissipation system provided in this embodiment includes: acquiring the temperature detected by a temperature-sensing optical fiber in real time, wherein the temperature-sensing optical fiber is used to detect the temperature of pipes and equipment in the heat dissipation system; determining the heat transfer law in the heat dissipation system based on the temperature change trend over time, the flow rate of the fluid in the heat dissipation system, and the physical properties of the pipes; if, based on the heat transfer law in the heat dissipation system, the rate of change of the temperature gradient at a target location in the heat dissipation system is determined to be greater than a preset temperature gradient rate of change threshold, then the target location is determined as a leak point; controlling the valve of the fluid functional unit where the leak point is located in the heat dissipation system to close, and controlling the corresponding target backup fluid functional unit to start. It has the following technical advantages: First, it enables continuous and blind-spot-free temperature detection of the entire heat dissipation system through temperature-sensing optical fibers. Second, after identifying the leak point, it can automatically control the valve of the fluid functional unit where the leak point is located to close, thereby automatically isolating the fault area and controlling the corresponding target backup fluid functional unit to start, achieving fault self-healing, minimizing the downtime of the heat dissipation system, and improving the heat dissipation effect. Third, it improves the accuracy of identifying the leak point by determining the heat transfer law in the heat dissipation system based on multi-dimensional data such as the trend of temperature change over time, the flow rate of the fluid in the heat dissipation system, and the physical properties of the pipes.

[0066] Figure 4 This is a flowchart of another control method for a heat dissipation system provided in an embodiment of the present invention. The control method for this heat dissipation system... Figure 1 Based on the illustrated embodiments and various optional implementations, other implementations of the method will be described in detail. For example... Figure 4 As shown, the control method of the heat dissipation system provided in this embodiment includes the following steps 401 to 412.

[0067] Step 401: Acquire the temperature detected by the temperature-sensing fiber optic cable in real time.

[0068] Among them, the temperature-sensing optical fiber is used to detect the temperature of pipes and equipment in the heat dissipation system.

[0069] Step 402: Determine the heat transfer pattern in the heat dissipation system based on the temperature change trend over time, the flow rate of the fluid in the heat dissipation system, and the physical properties of the pipes.

[0070] Step 403: If, based on the heat transfer law in the heat dissipation system, the rate of change of the temperature gradient at the target location in the heat dissipation system is determined to be greater than the preset temperature gradient rate of change threshold, then the target location is determined as the leakage point.

[0071] Step 404: Close the valve of the fluid function unit where the leak point is located in the heat dissipation system, and start the corresponding target backup fluid function unit.

[0072] The implementation process and technical principles of steps 401, 402, 403, 103, 404, and 104 are similar and will not be repeated here.

[0073] Step 405: Based on the heat source load of the heat dissipation system, the outdoor temperature, the outdoor humidity, and historical temperatures, predict the heat load change trend of the heat source.

[0074] In this embodiment, the heat load change trend is used to characterize the temperature change trend of the heat source.

[0075] Optionally, in a scenario where the heat source is a data center, the data center load may include at least one of the following: computing load, such as the utilization rate of the central processing unit; memory load, such as the memory occupancy rate; storage load, such as the frequency and amount of data for hard disk read / write operations; network load, such as the network bandwidth occupancy rate, etc.

[0076] Outdoor temperature can be detected by a temperature sensor, and outdoor humidity can be detected by a humidity sensor. In this embodiment, the historical temperature refers to the historical temperature collected by the temperature-sensing fiber optic cable under the same operating conditions of the heat source.

[0077] In related technologies, control strategies for the heat dissipation system are determined based on fixed thresholds, such as a 5°C temperature difference between the supply and return water. However, this approach cannot dynamically respond to changes in the heat load of the heat source, and the pump frequency adjustment relies on empirical formulas. The lack of data-driven, accurate predictive models leads to a lag in the optimization and adjustment of the heat dissipation system.

[0078] In this embodiment, the heat load change trend of the heat source is predicted by combining the heat source load, outdoor temperature, outdoor humidity and historical temperature, so that the operating parameters of the equipment in the heat dissipation system can be adjusted in advance according to the heat load change trend of the heat source.

[0079] Optionally, the heat load change trend in this embodiment can be the heat load change trend over a future period of time, such as the heat load change trend over the next 15 minutes.

[0080] Optionally, in order to improve the accuracy of the determined heat load change trend, in step 405, the load of the heat source of the heat dissipation system, the outdoor temperature, the outdoor humidity, and the historical temperature can be input into the heat load prediction model pre-trained by the machine learning algorithm to obtain the heat load change trend of the heat source output by the model.

[0081] Furthermore, in this embodiment, the actual operating results (such as energy consumption and temperature difference stability) can be continuously recorded, and the parameters of the heat load prediction model can be automatically corrected to adapt to long-term factors such as load fluctuations, pipeline aging, and seasonal changes.

[0082] Step 406: Determine the operating parameters of the equipment in the heat dissipation system based on the heat load change trend of the heat source.

[0083] The operating parameters include at least one of the following: water pump frequency, cooling tower fan speed, and valve opening degree.

[0084] Optionally, in step 406, the operating parameters of the equipment in the heat dissipation system can be determined based on the heat load variation trend of the heat source and the mapping relationship between the heat load variation trend of the heat source and the operating parameters of the equipment. That is, in this embodiment, the pump frequency, cooling tower fan speed, and valve opening can be dynamically adjusted according to the heat load variation trend of the heat source to ensure that the supply and return water temperature difference remains stable within the optimal range.

[0085] Furthermore, to save energy, step 406 can be implemented as follows: based on the heat load variation trend of the heat source, and with the goal of minimizing energy consumption while meeting cooling requirements, determine the operating parameters of the equipment in the heat dissipation system. In this embodiment, cooling requirements may include the temperature range after heat dissipation and control precision, etc. This implementation method can control the heat dissipation system to operate with minimal energy consumption while meeting cooling requirements, thus achieving energy efficiency optimization.

[0086] Step 407: Control the equipment to operate with the corresponding working parameters.

[0087] In this embodiment, the operating parameters can be determined based on the trend of heat load changes to anticipate temperature changes in the heat source. By controlling the equipment in the heat dissipation system to operate at the corresponding operating parameters, the heat dissipation effect of the heat dissipation system can be significantly improved.

[0088] Optionally, the method provided in this embodiment further includes the following steps 408 to 411.

[0089] Step 408: Based on the heat transfer pattern in the heat dissipation system, determine the temperature thermogram of the heat dissipation system and the temperature anomaly areas in the temperature thermogram.

[0090] The temperature heatmap in this embodiment visually represents the heat transfer pattern in the cooling system. The temperature anomaly area in this embodiment refers to the region where the temperature is below the minimum temperature threshold. It should be noted that the temperature anomaly area is not necessarily a faulty area; it is simply an area that requires close monitoring by maintenance personnel.

[0091] Step 409: Display the temperature heatmap in the data center management platform.

[0092] Step 410: Display the temperature anomaly area in the temperature heatmap using the first display strategy.

[0093] Step 411: Display the leak point on the temperature thermogram using the second display strategy.

[0094] The first display strategy differs from the second display strategy.

[0095] The display strategy in this embodiment includes at least one of the following: display color, display size, and display font. For example, the first display strategy in this embodiment can be blue, and the second display strategy can be red.

[0096] Figure 5 This is a schematic diagram of a display interface provided in an embodiment of the present invention. For example... Figure 5 As shown, in interface 51, the temperature abnormality area 52 is displayed in blue, and the leak point 53 is displayed in red.

[0097] The control method for the heat dissipation system provided in this embodiment, on the one hand, dynamically adjusts the operating parameters of equipment such as water pumps and fans based on real-time temperature field data and heat load prediction, breaking through the limitations of traditional fixed threshold control, significantly reducing ineffective energy consumption, and achieving adaptive control capabilities. On the other hand, through temperature field visualization and alarm linkage, it reduces reliance on manual inspections, improves fault location and handling efficiency, and enhances operation and maintenance efficiency. Furthermore, by combining historical temperature data and equipment status analysis, it provides decision support for pipeline maintenance and equipment replacement, extends the service life of key components, and achieves full lifecycle management of the heat dissipation system. Finally, it supports multi-fiber access and zone management, and can be adapted to heat dissipation systems of data centers of different sizes.

[0098] Figure 6 This is a schematic diagram of a control device for a heat dissipation system provided in an embodiment of the present invention. This device is installed in an electronic device. Figure 6 As shown, the control device for the heat dissipation system provided in this embodiment includes the following modules: an acquisition module 61, a first determination module 62, a second determination module 63, and a shutdown / startup module 64.

[0099] The acquisition module 61 is used to acquire the temperature detected by the temperature-sensing fiber optic cable in real time.

[0100] The temperature-sensing optical fiber is used to detect the temperature of the pipes and equipment in the heat dissipation system.
