[0072] The present application will be further described in detail below with reference to the accompanying drawings.

[0073] The embodiment of the present application provides a circulation control method for a double-layer water cooling circulating device, which can be executed by an electronic device, which can be a server or a terminal device. The server can be a physical server, a server cluster composed of multiple physical servers, a distributed system, or a cloud server providing cloud computing services. The terminal device can be a smartphone, a tablet computer, a desktop computer, or the like, but is not limited thereto.

[0074] 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 described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0075] In addition, the term "and / or" herein merely describes an association relationship of associated objects, and indicates that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects, unless otherwise specified.

[0076] The double-layer water cooling circulating device includes two levels of cooling circuits, each level is provided with a heat exchanger, a water pump, a frequency converter, and an electromagnetic valve group, and the two layers of cooling circuits can be switched between a series cooling mode and a parallel cooling mode through electromagnetic valves. The parallel cooling mode can significantly improve the delivery efficiency of the cooling liquid and is suitable for high heat load working conditions, and the series cooling mode is conducive to energy saving and consumption reduction and is suitable for light load or idle periods.

[0077] For example, in the parallel cooling mode, the double-layer water cooling circulating device is started by opening the shunt electromagnetic valves of the two levels and closing the series electromagnetic valves of the two levels, so that the two levels of cooling circuits operate independently. At this time, the water pumps of the two levels are synchronously operated, and the frequency converters increase the rotating speed of the water pumps to enhance the cooling effect. In the series cooling mode, the shunt electromagnetic valves of the two levels are closed, and the series electromagnetic valves of the two levels are opened, so that the cooling liquid forms a continuous flow path between the two levels. The water pump of one level is operated, and the frequency converter reduces the rotating speed of the water pump, thereby achieving the energy saving goal.

[0078] As shown in FIG. 1, Figure 1 A circulation control method for a double-layer water cooling circulating device, the main flow of the method is described as follows (steps S101-S105):

[0079] Step S101, acquiring temperature monitoring data, flow data and pressure data.

[0080] The temperature monitoring data includes heat source surface temperature and cooling liquid inlet and outlet temperature difference. The heat source surface temperature and the cooling liquid inlet and outlet temperature are acquired from the temperature sensors, and the cooling liquid inlet and outlet temperature difference is calculated according to the cooling liquid inlet and outlet temperature. The flow data is acquired from the flow sensors, and the pressure data is acquired from the pressure sensors.

[0081] Step S102, determining a mode adjustment threshold based on the temperature monitoring data and target temperature data.

[0082] The mode adjustment threshold includes a high temperature threshold and a low temperature threshold. According to the mode adjustment threshold, the temperature threshold for switching the series cooling mode and the parallel cooling mode can be determined.

[0083] Specifically, determining the mode adjustment threshold based on the temperature monitoring data and the target temperature data includes: calculating a deviation of the temperature monitoring data and the target temperature data; calculating a first product of the deviation and a proportional coefficient; acquiring a historical deviation; determining a second product based on the historical deviation and an integral coefficient; determining a third product based on the historical deviation and a differential coefficient; summing the first product, the second product and the third product to obtain a product sum; and adjusting the mode adjustment threshold based on the product sum.

[0084] In this embodiment, the current mode adjustment threshold is acquired from the staff or the database, and the PID algorithm is used to adjust the current mode adjustment threshold to obtain a new mode adjustment threshold. The specific adjustment method is as follows: the computer equipment that needs to be cooled is pre-set with target temperature data, the deviation is equal to the target temperature data minus the heat source surface temperature in the temperature monitoring data, and the first product (proportional term) is equal to the proportional coefficient multiplied by the deviation. The historical deviation is acquired from the database, the second product (integral term) is equal to the integral coefficient multiplied by the integral value of the historical deviation, the third product (differential term) is equal to the differential coefficient multiplied by the differential value (i.e. the change rate of the historical deviation) of the historical deviation, the product sum is equal to the first product plus the second product plus the third product, and the current mode adjustment threshold is adjusted according to the product sum. The proportional coefficient, the integral coefficient and the differential coefficient are pre-set and are not limited herein.

[0085] Specifically, adjusting the mode adjustment threshold based on the product sum includes: if the product sum is positive and greater than a first preset threshold, adjusting the mode adjustment threshold based on a decrement temperature; and if the product sum is negative and less than a second preset threshold, adjusting the mode adjustment threshold based on an increment temperature.

[0086] In the embodiment, the first preset threshold and the second preset threshold are both preset, and are not specifically limited herein. When the product sum is positive and greater than the first preset threshold, it indicates that the cooling needs to be increased, and the new mode adjustment threshold = the current mode adjustment threshold - the decrement temperature. When the product sum is negative and less than the second preset threshold, it indicates that the cooling needs to be reduced, and the new mode adjustment threshold = the current mode adjustment threshold + the increment temperature. It is worth noting 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 the cooling needs to be increased, the high-temperature threshold and the low-temperature threshold both need to be reduced by the decrement temperature, and when the cooling needs to be reduced, the high-temperature threshold and the low-temperature threshold both need to be increased by the increment temperature.

[0087] Specifically, before adjusting the mode adjustment threshold based on the product sum, the method further comprises: obtaining the heat capacity and the heat transfer rate of the device; determining the temperature stability level based on the heat capacity and the heat transfer rate; determining the initial increment temperature and the initial decrement temperature based on the temperature stability level; 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.

[0088] In the embodiment, the heat capacity and the heat transfer rate of the double-layer water cooling circulating device are obtained from the database or the staff. The database stores the correspondence between the heat capacity, the heat transfer rate and the temperature stability level, and the correspondence between the initial increment temperature, the initial decrement temperature and the temperature stability level. The temperature stability level is obtained from the database according to the heat capacity and the heat transfer rate, and the initial increment temperature and the initial decrement temperature are obtained from the database according to the temperature stability level. When the deviation exceeds the third preset threshold (preset, not specifically limited herein), the initial increment temperature and the initial decrement temperature need to be adjusted to improve the cooling effect faster. The increment temperature = the initial increment temperature × the deviation / third preset threshold, and the decrement temperature = the initial decrement temperature × the deviation / third preset threshold.

[0089] Step S103, determining a mode adjustment strategy based on the temperature monitoring data and the mode adjustment threshold.

[0090] The mode adjustment strategy is an adjustment strategy of the cooling mode, and the cooling mode includes a parallel cooling mode and a series cooling mode.

[0091] Specifically, determining the mode adjustment strategy based on the temperature monitoring data and the mode adjustment threshold comprises: determining a parallel adjustment threshold based on the high-temperature threshold and the hysteresis interval value; if the heat source surface temperature is higher than the parallel adjustment threshold, or the cooling liquid inlet and outlet temperature difference is greater than the preset temperature difference upper limit, the mode adjustment strategy is to activate the parallel cooling mode; determining a series adjustment threshold based on the low-temperature threshold and the hysteresis interval value; if the heat source surface temperature is lower than the series adjustment threshold, and the cooling liquid inlet and outlet temperature difference is less than the preset temperature difference lower limit, the mode adjustment strategy is to activate the series cooling mode.

[0092] In the embodiment, the parallel adjustment threshold value = high temperature threshold value + hysteresis interval value (pre-set, not specifically defined here), if the heat source surface temperature is higher than the parallel adjustment threshold value, or the cooling liquid inlet and outlet temperature difference is greater than the preset temperature difference upper limit (pre-set, not specifically defined here), the mode adjustment strategy is to activate the parallel cooling mode, that is, the series cooling mode is adjusted to the parallel cooling mode at this time, so as to improve the heat dissipation efficiency; the series adjustment threshold value = low temperature threshold value + hysteresis interval value, if the heat source surface temperature is lower than the series adjustment threshold value and the cooling liquid inlet and outlet temperature difference is less than the preset temperature difference lower limit (pre-set, not specifically defined here), the mode adjustment strategy is to activate the series cooling mode, that is, the parallel cooling mode is adjusted to the series cooling mode at this time, so as to reduce the heat dissipation efficiency and save energy consumption, wherein the parallel adjustment threshold value is greater than the series adjustment threshold value, and the preset temperature difference upper limit is greater than the preset temperature difference lower limit, if the heat source surface temperature and the cooling liquid inlet and outlet temperature difference do not meet the above two conditions, the current cooling mode is maintained, and the additional energy consumption caused by frequent switching is reduced.

[0093] Step S104, analyze the temperature monitoring data, flow data and pressure data to determine the cooling control strategy.

[0094] Specifically, the temperature monitoring data, flow data and pressure data are analyzed to determine the cooling control strategy, including: calculating the pressure difference of 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 adjustment strategy based on the flow data; determining the cooling demand based on the cooling liquid inlet and outlet temperature difference; determining the water pump speed adjustment direction based on the cooling demand; determining the speed adjustment amount based on the cooling liquid inlet and outlet temperature difference and the current water pump speed; determining the water pump adjustment strategy based on the water pump speed adjustment direction and the speed adjustment amount; determining the cooling control strategy based on the pressure adjustment strategy, the flow adjustment strategy and the water pump adjustment strategy.

[0095] In the embodiment, the pressure data of adjacent positions are subtracted to obtain the pressure difference of each two positions, the region between the two positions with the pressure difference exceeding a preset pressure difference range (pre-set, not specifically limited here) is determined as the pressure abnormal region, and the pressure adjustment strategy is: if the pressure difference is less than the preset pressure difference range, the valve of the pressure abnormal region is closed or the staff is reminded to check whether there is leakage; if the pressure difference is greater than the preset pressure difference range, the valve of the pressure abnormal region is opened or the staff is reminded to take corresponding measures; the database stores adjustment strategies of different flow data, the flow adjustment strategy is found from the database according to the flow data; if the temperature difference of the cooling liquid inlet and outlet is greater than a preset upper limit of the temperature difference, the cooling demand is to improve the cooling efficiency, and the water pump speed adjustment direction is to increase the speed; if the temperature difference of the cooling liquid inlet and outlet is less than a preset lower limit of the temperature difference, the cooling demand is to reduce the cooling efficiency, and the water pump speed adjustment direction is to reduce the speed; otherwise, the cooling demand is to not adjust the cooling efficiency, that is, the water pump speed is not adjusted; the database stores the corresponding relationship among the temperature difference of the cooling liquid inlet and outlet, the current water pump speed and the speed adjustment amount, the speed adjustment amount is found from the database according to the temperature difference of the cooling liquid inlet and outlet and the current water pump speed, and the water pump adjustment strategy is to adjust the current water pump speed according to the water pump speed adjustment direction and the speed adjustment amount. The pressure adjustment strategy, the flow adjustment strategy and the water pump adjustment strategy are collectively determined as the cooling control strategy.

[0096] In step S105, the circulation control strategy is determined based on the mode adjustment strategy and the cooling control strategy.

[0097] The mode adjustment strategy and the cooling control strategy are collectively determined as the circulation control strategy.

[0098] Specifically, the method further comprises: acquiring water pump state data; determining whether the water pump has a fault based on the water pump state data; generating a fault warning information if the water pump has a fault; determining a current cooling mode; and determining an emergency strategy based on the current cooling mode and the fault warning information.

[0099] In the embodiment, the water pump state data is acquired from each monitoring device (sensor or the like) of the water pump, and the water pump state data is compared with a standard data range (pre-set, which can be acquired from a database). If the water pump state data exceeds the standard data range, the water pump has a fault, and a fault warning information is generated. The fault warning information includes the water pump having a fault and the water pump state data exceeding the standard data range. The current cooling mode is acquired from the double-layer water cooling circulation device, and the emergency strategy is: if the current cooling mode is the series cooling mode, the cooling work is completed by using the water pump without a fault; if the current cooling mode is the parallel cooling mode, the parallel cooling mode is switched to the series cooling mode, and the cooling work is completed by using the water pump without a fault.
