[0016] By adopting the above technical solution, by quickly locating the pressure abnormal area and then formulating a targeted pressure adjustment strategy, the pressure stability can be improved; by determining the flow rate adjustment strategy through the flow rate data, the precise control of the coolant flow rate can be realized, and the cooling efficiency can be improved; by determining the cooling demand according to the temperature difference between the inlet and outlet of the coolant, and further determining the adjustment direction and adjustment amount of the water pump speed, a reasonable water pump adjustment strategy can be formulated, which can optimize the cooling effect and reduce energy consumption; by integrating the pressure adjustment strategy, the flow rate adjustment strategy, and the water pump adjustment strategy to form a comprehensive cooling control strategy, the overall performance and reliability of the double-layer water-cooled circulation device are improved.

[0017] Optionally, the method further includes: Obtaining the water pump status data; Judging whether the water pump has a fault based on the water pump status data; If the water pump has a fault, generating a fault warning message; Determining the current cooling mode; Determining an emergency strategy based on the current cooling mode and the fault warning message.

[0026] The following further describes the present application in detail with reference to the accompanying drawings.

[0027] An embodiment of the present application provides a circulation control method for a double - layer water - cooled circulation device. This circulation control method for the double - layer water - cooled circulation device can be executed by an electronic device, which can be a server or a terminal device. The server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a desktop computer, etc., but is not limited thereto.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0029] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the front and back associated objects unless otherwise specified.

[0030] The double - layer water - cooled circulation device includes two levels of cooling circuits. A heat exchanger, a water pump, a frequency converter, and a solenoid valve group are provided in each level. The two - layer cooling circuits can be switched between a series cooling mode or a parallel cooling mode through solenoid valves. Among them, the parallel cooling mode can significantly improve the delivery efficiency of the coolant and is suitable for high - heat - load working conditions, while the series cooling mode is beneficial to energy conservation and consumption reduction and is suitable for use during light - load or idle periods.

[0031] For example: In the parallel cooling mode, the double-layer water-cooled circulation device makes the cooling circuits of the two levels operate independently by opening the shunt solenoid valves of the two levels and closing the series solenoid valves of the two levels. At this time, the water pumps of the two levels operate synchronously, and the frequency converter increases the rotation speed of the water pumps to enhance the cooling effect. In the series cooling mode, the shunt solenoid valves of the two levels are closed, and the series solenoid valves of the two levels are opened to form a continuous flow path of the coolant between the two levels. One of the water pumps operates, and the frequency converter reduces the rotation speed of the water pump to achieve the energy-saving goal.

[0032] As Figure 1 shown, a circulation control method for a double-layer water-cooled circulation device, the main process of the method is described as follows (steps S101 to S105): Step S101, obtain temperature monitoring data, flow data, and pressure data.

[0033] Temperature sensors, flow sensors, and pressure sensors are installed at multiple positions of the double-layer water-cooled circulation device. The temperature monitoring data includes the surface temperature of the heat source and the temperature difference between the inlet and outlet of the coolant. The surface temperature of the heat source and the inlet and outlet temperatures of the coolant are obtained from the temperature sensors, and the temperature difference between the inlet and outlet of the coolant is calculated based on the inlet and outlet temperatures of the coolant. The flow data is obtained from the flow sensors, and the pressure data is obtained from the pressure sensors.

[0034] Step S102, determine the mode adjustment threshold based on the temperature monitoring data and the target temperature data.

[0035] Among them, the mode adjustment threshold includes a high-temperature threshold and a low-temperature threshold. According to the mode adjustment threshold, the temperature thresholds for switching between the series cooling mode and the parallel cooling mode can be determined.

[0036] Specifically, determining the mode adjustment threshold based on the temperature monitoring data and the target temperature data includes: calculating the deviation between the temperature monitoring data and the target temperature data; calculating the first product of the deviation and the proportionality coefficient; obtaining the historical deviation; determining the second product based on the historical deviation and the integral coefficient; determining the third product based on the historical deviation and the differential coefficient; summing the first product, the second product, and the third product to obtain the product sum; adjusting the mode adjustment threshold based on the product sum.

[0037] In this embodiment, the current mode adjustment threshold is obtained from a staff member or a database, and then the current mode adjustment threshold is adjusted through a PID algorithm to obtain a new mode adjustment threshold. The specific adjustment method is as follows: The computer device that needs heat dissipation is pre-set with target temperature data. The deviation = target temperature data - surface temperature of the heat source in the temperature monitoring data. The first product (proportional term) = proportional coefficient × deviation. The historical deviation is obtained from the database. The second product (integral term) = integral coefficient × integral value of the historical deviation. The third product (differential term) = differential coefficient × differential value of the historical deviation (i.e., the change rate of the historical deviation). The sum of products = first product + second product + third product. The current mode adjustment threshold is adjusted according to the sum of products. Among them, the proportional coefficient, the integral coefficient, and the differential coefficient are all pre-set and are not specifically limited here.

[0038] Specifically, adjusting the mode adjustment threshold based on the sum of products includes: If the sum of products is positive and greater than the first preset threshold, the mode adjustment threshold is adjusted based on the decrement temperature; if the sum of products is negative and less than the second preset threshold, the mode adjustment threshold is adjusted based on the increment temperature.

[0039] In this embodiment, both the first preset threshold and the second preset threshold are pre-set and are not specifically limited here. When the sum of products is positive and greater than the first preset threshold, it indicates that increased cooling is required. The new mode adjustment threshold = current mode adjustment threshold - decrement temperature; when the sum of products is negative and less than the second preset threshold, it indicates that decreased cooling is required. The new mode adjustment threshold = current mode adjustment threshold + increment temperature. It should be noted that the high temperature threshold and the low temperature threshold in the mode adjustment threshold are both processed in the same way, that is, when increased cooling is required, both the high temperature threshold and the low temperature threshold need to subtract the decrement temperature, and when decreased cooling is required, both the high temperature threshold and the low temperature threshold need to add the increment temperature.

[0040] Specifically, before adjusting the mode adjustment threshold based on the sum of products, the method further includes: obtaining the heat capacity and heat transfer rate of the device; determining the temperature stability level based on the heat capacity and heat transfer rate; determining the initial increment temperature and the initial decrement temperature based on the temperature stability level; and adjusting the initial increment temperature and the initial decrement temperature based on the deviation and the third preset threshold to obtain the increment temperature and the decrement temperature.

[0041] In this embodiment, the heat capacity and heat transfer rate of the double-layer water-cooled circulation device are obtained from a database or from a staff member. The database stores the corresponding relationships between the heat capacity, heat transfer rate and temperature stability level, as well as the corresponding relationships between the initial incremental temperature, initial decremental temperature and temperature stability level. The temperature stability level is obtained from the database based on the heat capacity and heat transfer rate, and the initial incremental temperature and initial decremental temperature are obtained from the database based on the temperature stability level. When the deviation exceeds the third preset threshold (pre-set, not specifically limited here), in order to improve the cooling effect more quickly, at this time, it is necessary to adjust the initial incremental temperature and initial decremental temperature. The incremental temperature = initial incremental temperature × deviation / third preset threshold, and the decremental temperature = initial decremental temperature × deviation / third preset threshold.

[0042] Step S103: Determine the mode adjustment strategy based on the temperature monitoring data and the mode adjustment threshold.

[0043] Among them, the mode adjustment strategy is the adjustment strategy of the cooling mode, and the cooling mode includes a parallel cooling mode and a series cooling mode.

[0044] Specifically, determining the mode adjustment strategy based on the temperature monitoring data and the mode adjustment threshold includes: determining the parallel adjustment threshold based on the high temperature threshold and the hysteresis interval value; if the temperature on the surface of the heat source is higher than the parallel adjustment threshold, or the temperature difference between the inlet and outlet of the coolant is greater than the preset upper temperature difference limit, then the mode adjustment strategy is to activate the parallel cooling mode; determining the series adjustment threshold based on the low temperature threshold and the hysteresis interval value; if the temperature on the surface of the heat source is lower than the series adjustment threshold and the temperature difference between the inlet and outlet of the coolant is less than the preset lower temperature difference limit, then the mode adjustment strategy is to activate the series cooling mode.

[0045] In this embodiment, the parallel adjustment threshold = high temperature threshold + hysteresis interval value (pre-set, not specifically limited here). If the temperature on the surface of the heat source is higher than the parallel adjustment threshold, or the temperature difference between the inlet and outlet of the coolant is greater than the preset upper temperature difference limit (pre-set, not specifically limited here), then the mode adjustment strategy is to activate the parallel cooling mode, that is, at this time, the series cooling mode is adjusted to the parallel cooling mode to improve the heat dissipation efficiency; the series adjustment threshold = low temperature threshold + hysteresis interval value. If the temperature on the surface of the heat source is lower than the series adjustment threshold and the temperature difference between the inlet and outlet of the coolant is less than the preset lower temperature difference limit (pre-set, not specifically limited here), then the mode adjustment strategy is to activate the series cooling mode, that is, at this time, the parallel cooling mode is adjusted to the series cooling mode to reduce the heat dissipation efficiency and save energy consumption. Among them, the parallel adjustment threshold is greater than the series adjustment threshold, and the preset upper temperature difference limit is greater than the preset lower temperature difference limit. If the temperature on the surface of the heat source and the temperature difference between the inlet and outlet of the coolant do not meet the above two conditions, then the current cooling mode is maintained to reduce the additional energy consumption caused by frequent switching.

[0046] Step S104: Analyze the temperature monitoring data, flow rate data, and pressure data to determine the cooling control strategy.

[0047] Specifically, analyzing the temperature monitoring data, flow rate data, and pressure data to determine the cooling control strategy includes: calculating the pressure difference at each position based on the pressure data; if the pressure difference exceeds the preset pressure difference range, determining the pressure abnormal area; determining the pressure adjustment strategy based on the pressure abnormal area; determining the flow rate adjustment strategy based on the flow rate data; determining the cooling demand based on the temperature difference between the inlet and outlet of the coolant; determining the adjustment direction of the water pump speed based on the cooling demand; determining the speed adjustment amount based on the temperature difference between the inlet and outlet of the coolant and the current water pump speed; determining the water pump adjustment strategy based on the adjustment direction of the water pump speed and the speed adjustment amount; and determining the cooling control strategy based on the pressure adjustment strategy, flow rate adjustment strategy, and water pump adjustment strategy.

[0048] In this embodiment, the pressure data at adjacent positions are subtracted to obtain the pressure difference between each two positions, and the area between the two positions where the pressure difference exceeds the preset pressure difference range (pre-set, not specifically limited here) is determined as the pressure abnormal area. The pressure adjustment strategy is: if the pressure difference is less than the preset pressure difference range, close the valve in the pressure abnormal area or remind the staff to check for leaks; if the pressure difference is greater than the preset pressure difference range, open the valve in the pressure abnormal area or remind the staff to take corresponding measures; the adjustment strategies for different flow rate data are stored in the database, and the flow rate adjustment strategy is found from the database according to the flow rate data; if the temperature difference between the inlet and outlet of the coolant is greater than the preset upper temperature difference limit, the cooling demand is to improve the cooling efficiency, and the adjustment direction of the water pump speed is to increase the speed; if the temperature difference between the inlet and outlet of the coolant is less than the preset lower temperature difference limit, the cooling demand is to reduce the cooling efficiency, and the adjustment direction of the water pump speed is to decrease the speed; otherwise, the cooling demand is not to adjust the cooling efficiency, that is, there is no need to adjust the water pump speed. The corresponding relationship between the temperature difference between the inlet and outlet of the coolant, the current water pump speed, and the speed adjustment amount is stored in the database, and the speed adjustment amount is found from the database according to the temperature difference between the inlet and outlet of the coolant and the current water pump speed. The water pump adjustment strategy is to adjust the current water pump speed according to the adjustment direction of the water pump speed and the speed adjustment amount, and the pressure adjustment strategy, flow rate adjustment strategy, and water pump adjustment strategy are jointly determined as the cooling control strategy.

[0049] Step S105: Determine the circulation control strategy based on the mode adjustment strategy and the cooling control strategy.

[0050] The mode adjustment strategy and the cooling control strategy are jointly determined as the circulation control strategy.

[0051] Specifically, the method further includes: obtaining the water pump status data; judging whether the water pump has a fault based on the water pump status data; if the water pump has a fault, generating a fault warning message; determining the current cooling mode; and determining the emergency strategy based on the current cooling mode and the fault warning message.

[0052] In this embodiment, pump status data is obtained from various monitoring devices (such as sensors) of the pump, and the pump status data is compared with a standard data range (pre-set and can be obtained from a database). If the pump status data exceeds the standard data range, the pump has a fault, and a fault warning message is generated. The fault warning message includes the pump with the fault and the pump status data that exceeds the standard data range. The current cooling mode is obtained from the double-layer water-cooled circulation device. The emergency strategy is as follows: If the current cooling mode is a series cooling mode, the pumps without faults are used to complete the cooling work; if the current cooling mode is a parallel cooling mode, the parallel cooling mode is switched to a series cooling mode, and the pumps without faults are used to complete the cooling work.
