[0002] With the rapid development of power electronics technology, the application of various power devices in daily production and life has become increasingly widespread. Considering the safety issues brought about by the high performance of power devices, it is necessary to dissipate the heat of power devices in a timely manner during actual use to ensure that they are stably in a good working state and reduce their safety hazards. At present, water cooling systems are mainly used to dissipate the heat of power devices. Specifically, each module in the water cooling system is uniformly scheduled through integrated control instructions to achieve heat dissipation control for power devices.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] It should be noted that although the functional modules are divided in the device schematic and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart.

[0018] like Figure 1 As shown, the water cooling unit 100 can be applied to, but is not limited to, a power unit 200, which includes but is not limited to: The heat dissipation element 110 is used to be disposed in close contact with the power unit 200 to dissipate heat from the power unit 200; The cold exhaust fan 130 is disposed on both sides of the heat dissipation element 110 and is used for circulating cooling and ventilation through the refrigerant medium; A first fan 150 is disposed at one side of the air inlet of the heat dissipation element 110 and is used to supply air to the heat dissipation element 110; The second fan 140 is disposed at one side of the air outlet of the heat dissipation element 110 and is used to conduct heat from the heat dissipation element 110 to the outside of the water cooling unit 100; The flow pump 120 is disposed on one side of the cold exhaust fan 130 and is used to provide water cooling flow for the water cooling unit 100 .

[0019] It can be seen that a variety of water-cooling elements including a heat dissipation element 110, a cold exhaust fan 130, a first fan 150, a second fan 140 and a flow pump 120 are provided in the water-cooling unit 100 to perform good and stable heat dissipation and refrigeration of the power unit 200, wherein the heat dissipation element 110 provides heat dissipation for the power unit 200, the cold exhaust fan 130 is used to cool and ventilate the internal environment of the water-cooling unit 100 through the refrigerant medium inside the water-cooling unit 100, the first fan 150 is used as an air supply fan, the second fan 140 is used as a heat conduction fan, and the flow pump 120 can be used but not Limited to the use of a water pump, when the flow pump 120 is a water pump, it is used to provide water flow for the water cooling unit 100; the specifications of the heat dissipation element 110, each fan and the flow pump 120 can be set accordingly according to the specific situation. Since this part of the content does not belong to the invention point of the present invention, this embodiment does not impose specific restrictions on this; the power unit 200 can be set accordingly according to different usage scenarios. For example, it can be a high-voltage inverter component that performs rectification, filtering or inversion based on related power electronic devices, or it can be a power amplifier integrated with related peripheral circuits, etc., which is not limited here.

[0020] It should be noted that Figure 1 Only one integrated module architecture of the water cooling unit 100 is shown, and there is no limitation on its specific installation and setting method. In fact, it can be set in a variety of ways according to different application scenarios. For example, please refer to Figure 2 The power unit 200 is centrally arranged and attached to the corresponding heat dissipation element 110. The first fan 150 is arranged at the front position of the heat dissipation element 110 and is aligned with the air inlet side of the heat dissipation element 110. A row of long strip-shaped air holes are opened on the side of the water cooling unit 100 so that the corresponding cold exhaust fan 130 on the side can circulate and cool and ventilate. The second fan 140 is arranged below the air holes on the side and is aligned with the air outlet side of the heat dissipation element 110. The flow pump 120 is arranged at the side and lower position of the cold exhaust fan 130. In the water cooling unit 100, the circulation of the refrigerant medium can effectively absorb the heat generated by the power unit 200. Through the circulation of the refrigerant medium, this part of the heat is transferred to the heat dissipation element 110 for heat exchange. After being processed by each fan, the cooled refrigerant medium flows back again to form a cycle, thereby reducing the working temperature of the power unit 200 and achieving the technical effect of heat dissipation and refrigeration.

[0021] The water cooling unit 100 and the application scenario described in the embodiment of the present invention are intended to more clearly illustrate the technical solution of the embodiment of the present invention, and do not constitute a limitation on the technical solution provided by the embodiment of the present invention. Those skilled in the art can know that with the evolution of the water cooling unit 100 and the emergence of new application scenarios, the technical solution provided by the embodiment of the present invention is also applicable to similar technical problems.

[0022] It can be understood by those skilled in the art that Figure 1 or Figure 2 The water cooling unit 100 shown in the figure does not constitute a limitation on the embodiment of the present invention, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0023] based on Figure 1 or Figure 2 The structure of the water cooling unit is shown in the figure, and various embodiments of the operation control method of the present invention are proposed.

[0024] Figure 3 This is a flow chart of an operation control method for a water cooling unit provided in one embodiment of the present invention. The operation control method may include but is not limited to steps S1 to S3.

[0025] Step S1, collecting multiple real-time operating parameters of the water cooling unit, and obtaining the real-time operating conditions of the cold exhaust fan, the first fan, the second fan and the flow pump respectively operating on the power unit; Among them, the real-time operating parameters may be, but are not limited to, all relevant operating parameters involved in the water-cooled unit, including usage status parameters, environmental parameters and other data, which can be set accordingly according to different application scenarios, for example, may include, but are not limited to, the real-time temperature and real-time power of the cold exhaust fan and the real-time temperature of the power unit, the real-time flow rate, real-time rotation speed and refrigerant medium temperature of the flow pump, the air inlet temperature of the heat dissipation element and the real-time temperature of the first fan, the air outlet temperature of the heat dissipation element, the real-time temperature of the second fan and the internal environmental humidity of the water-cooled unit, etc.; the real-time operating conditions of the cold exhaust fan, the first fan, the second fan and the flow pump for the power unit respectively, which are used to reflect the operating conditions of each water-cooled component in the current state, such as whether the first fan is turned on, whether the cold exhaust fan is ventilated normally, etc., so that the user can promptly know the actual operating status of each water-cooled component; Step S2, according to the real-time operation conditions of the cold exhaust fan, the first fan, the second fan and the flow pump respectively operating on the power unit, a plurality of real-time operation parameters are divided to obtain a plurality of associated parameter groups, wherein each associated parameter group corresponds to one of the real-time operation conditions of the power unit, and any associated parameter group includes at least one real-time operation parameter; For example, when it is confirmed that the cold exhaust fan is in working state, multiple real-time operation parameters related to the operation of the cold exhaust fan are divided into an associated parameter group belonging to the cold exhaust fan, that is, the real-time temperature, real-time power and real-time temperature of the power unit of the cold exhaust fan are divided into an associated parameter group, and in the subsequent process, the associated parameter group is analyzed as a separate case, and then a corresponding operation control strategy is formulated for it, and so on, it is possible to obtain associated parameter groups corresponding to each water cooling element, thereby determining all associated parameter groups; Step S3: for each associated parameter group, generate an operation control strategy oriented to the real-time operation situation corresponding to the associated parameter group according to the associated parameter group.

[0026] In this step, a variety of water-cooling elements including a heat dissipation element, a cold exhaust fan, a first fan, a second fan and a flow pump are provided in the water-cooling unit to dissipate heat and cool the power unit in a good and stable manner. In particular, in the process of dissipating heat and cooling the power unit, multiple real-time operating parameters of the water-cooling unit are divided according to the real-time operating conditions of the cold exhaust fan, the first fan, the second fan and the flow pump respectively operating on the power unit, thereby obtaining multiple associated parameter groups. Since each associated parameter group corresponds to one of the real-time operating conditions of the power unit, that is, each associated parameter group corresponds to the real-time operating condition of one of the water-cooling elements, an operation control strategy for the corresponding water-cooling element can be generated based on each associated parameter group, so that each water-cooling element can be separately distinguished and adjusted. Since the real-time operating conditions of each water-cooling element are taken into consideration and combined with the corresponding real-time operating parameters, the adjustment effect of the water-cooling element on the power unit can be optimized, thereby improving the heat dissipation and refrigeration performance of the water-cooling unit as a whole, extending the service life of the water-cooling unit, and realizing intelligent operation control.

[0027] An embodiment of the present invention, please refer to Figure 4 When the associated parameter group includes the real-time temperature of the exhaust fan and the real-time temperature of the power unit, step S3 may include but is not limited to steps S310 to S314, wherein the real-time temperature of the exhaust fan may be but is not limited to being characterized as the real-time temperature of the water-cooled copper bus or water-cooled radiator corresponding to the exhaust fan.

[0028] Step S310: continuously obtaining the real-time temperature of the cold exhaust fan, the real-time temperature of the power unit, and the real-time power of the cold exhaust fan within a preset first sampling time period; Step S311, calculating the average power of the cold exhaust fan in the first sampling time period, and determining whether the average power of the cold exhaust fan is within a preset power threshold range, if so, executing step S312, otherwise controlling the cold exhaust fan to stop running; Step S312, selecting a real-time temperature with the largest temperature value from the real-time temperatures of all the cold exhaust fans and the real-time temperatures of the power units as the real-time screening temperature; Step S313, calculating the difference between the real-time screening temperature and the preset expected temperature to obtain a first temperature error parameter, and performing PID normalization calculation based on the first temperature error parameter to obtain a first PWM duty cycle; Step S314, control the cold exhaust fan to operate with a first PWM duty cycle, and detect the real-time speed of the cold exhaust fan, wherein, during the process of detecting the real-time speed of the cold exhaust fan, when it is detected that the real-time speed of the cold exhaust fan is not within a preset speed threshold range, the real-time speed of the cold exhaust fan is adjusted to the maximum rated speed.

[0029] In this step, the working state of the cold exhaust fan is controlled. First, it is determined whether the average power of the cold exhaust fan in the first sampling time period is within the preset power threshold range. If so, it means that the average power in the first sampling time period is a normal value. Then it can be determined that the cold exhaust fan is in normal working state at this time, that is, it is suitable for adjustment and control. Otherwise, it means that it is not in normal working state, and the cold exhaust fan should be controlled to stop running. If necessary, an alarm function can be configured to shut it down for maintenance to prevent greater safety hazards. Then, the real-time screening temperature with the largest temperature value is obtained from the real-time temperatures of all cold exhaust fans and the real-time temperatures of power units. This real-time screening temperature is used as a reference temperature , and perform PID normalization calculation on the difference between it and the preset expected temperature, i.e., the first temperature error parameter, to obtain a first PWM duty cycle. The first PWM duty cycle is not equivalent to the final PWM duty cycle. It is necessary to detect the real-time speed of the cold exhaust fan in the process of controlling the cold exhaust fan to operate with the first PWM duty cycle. If it is detected that the real-time speed of the cold exhaust fan is not within the preset speed threshold range, it means that the real-time speed of the cold exhaust fan at this time does not meet the requirement, and therefore the real-time speed of the cold exhaust fan should be adjusted to the maximum rated speed. On the contrary, if it is within the preset speed threshold range, it means that the real-time speed of the cold exhaust fan at this time meets the requirement, and then the first PWM duty cycle can be maintained to continue to operate the cold exhaust fan.

[0030] It should be noted that the specific division of the first sampling time period needs to be independently selected according to the actual scenario, which will not be elaborated here; the preset power threshold range, preset speed threshold range, preset expected temperature and maximum rated speed need to be set accordingly according to the specific configuration of the exhaust fan and power unit, and are not restricted here.

[0031] In one embodiment, in step S310, the purpose of continuously acquiring the real-time temperature of the exhaust fan, the real-time temperature of the power unit, and the real-time power of the exhaust fan is to collect relevant data within the first sampling time period multiple times, so that before executing subsequent steps, the multiple sampled data can be averaged filtered, arithmetic averaged, etc. to improve the smoothness of the data. Alternatively, technical personnel in this field can also use other similar methods to pre-process the sampled data, which is not limited here.

[0032] In one embodiment, the PID normalization calculation based on the first temperature error parameter in step S313 can be performed in a variety of ways, which are not limited here. For example, the following normalization calculation formula can be used for calculation, but is not limited to: ; in, is the first PWM duty cycle, is the first PID calculation factor, Calculate the factor for the second PID, is the third PID calculation factor, is the first temperature error parameter, , To filter the temperature in real time, To preset the desired temperature.

[0033] An embodiment of the present invention, please refer to Figure 5 When the associated parameter group includes the real-time flow rate, real-time rotation speed and refrigerant medium temperature of the flow pump, step S3 may include but is not limited to steps S320 to S324.

[0034] Step S320: continuously obtain the real-time flow rate, real-time rotation speed and refrigerant medium temperature of the flow pump within a preset second sampling time period; Step S321: construct a preliminary application model corresponding to the flow pump according to the real-time flow rate, real-time rotation speed and temperature of the refrigerant medium of the flow pump; Step S322, calculating the application model error of the flow pump based on the preliminary application model, and obtaining the minimum value of the application model error; Step S323: determining a model-related parameter according to the minimum value of the application model error, and updating the preliminary application model based on the model-related parameter to obtain a target application model; Step S324: predict the flow rate of the flow pump through the target application model to obtain the predicted flow rate of the flow pump, and adjust the real-time speed of the flow pump according to the predicted flow rate and real-time flow rate of the flow pump to control the refrigerant temperature of the flow pump.

[0035] In this step, the working state of the flow pump is controlled. First, a corresponding preliminary application model is constructed according to the real-time flow rate, real-time rotation speed and refrigerant medium temperature of the flow pump. Then, the application model error of the flow pump is calculated through the preliminary application model, that is, the theoretical error of the flow pump when operating based on the preliminary application model is calculated. The theoretical error is the application model error. When the minimum value of the application model error is obtained, it is equivalent to determining the situation of the preliminary application model with the minimum error. Therefore, the model association parameters associated with the preliminary application model can be determined accordingly, and the preliminary application model can be updated based on the model association parameters to obtain the required reliable target application model. Finally, the flow rate of the flow pump can be predicted through the target application model, and the real-time rotation speed of the flow pump can be adjusted according to the predicted flow rate and real-time flow rate of the flow pump to control the refrigerant medium temperature of the flow pump and realize intelligent operation control; that is, when the temperature of the refrigerant medium increases or the flow rate of the flow pump increases, the rotation speed of the flow pump will be automatically increased through this control method to enhance fluid circulation and improve heat exchange efficiency; conversely, when the temperature of the refrigerant medium decreases or the flow rate of the flow pump decreases, the rotation speed of the flow pump will also decrease accordingly, thereby reducing energy consumption and avoiding unnecessary energy waste.

[0036] It should be noted that the specific division of the second sampling time period needs to be independently selected according to the actual scenario, which will not be elaborated here; there can be many ways to adjust the real-time rotation speed of the flow pump according to the predicted flow rate and real-time flow rate of the flow pump in step S324. For example, it can be calculated with reference to the normalized calculation formula shown in the aforementioned embodiment, that is, similarly, the real-time flow rate is subtracted from the predicted flow rate, and the difference can be substituted into the normalized calculation formula for calculation. The relevant constant parameter values ​​can be adaptively adjusted according to the specific situation, which will not be elaborated here.

[0037] In one embodiment, in step S320, the purpose of continuously acquiring the real-time flow rate, real-time rotation speed and refrigerant medium temperature of the flow pump is to collect relevant data within the second sampling time period multiple times, so that before executing subsequent steps, the multiple sampled data can be averaged filtered, arithmetic averaged and other operations can be performed to improve the smoothness of the data. Alternatively, technical personnel in this field can also use other similar methods to pre-process the sampled data, which is not limited here.

[0038] In one embodiment, the application model error of the flow pump may be, but is not limited to: ; in, is the application model error of the flow pump, is the first sampling period in the second sampling period The real-time flow rate of the flow pump corresponding to a time point, is the first sampling period in the second sampling period The real-time speed of the flow pump corresponding to a time point, is the first sampling period in the second sampling period The refrigerant medium temperature of the flow pump corresponding to the time point, is the total number of time points in the second sampling period, is the first preset operation factor, is the second preset operation factor, is the third preset operation factor.

[0039] It should be noted that the time point can be set accordingly according to the specific scenario. For example, in the second sampling time period, the records are archived every half hour, that is, every half hour is regarded as a node, which can be regarded as a time point. Then the first time point is the 30th minute after the start of the second sampling time period, the 60th minute is the second time point, the 90th minute is the third time point, and so on, so that all the time points in the second sampling time period can be determined; The target application model can be, but is not limited to: ; in, is the predicted flow rate of the flow pump, is the real-time flow rate of the flow pump, is the refrigerant medium temperature of the flow pump.

[0040] An embodiment of the present invention, please refer to Figure 6 When the associated parameter group includes the air inlet temperature of the heat dissipation element and the real-time temperature of the first fan, step S3 may include but is not limited to steps S330 to S334, wherein the real-time temperature of the first fan may be but is not limited to being characterized as the real-time temperature of the heat dissipation element on the air inlet side.

[0041] Step S330: within a preset third sampling time period, continuously obtain the air inlet temperature of the heat dissipation element and the real-time temperature of the first fan, and summarize the air inlet temperatures of all heat dissipation elements and the real-time temperatures of the first fan to obtain a temperature summary set; Step S331, dividing the temperature summary set into a plurality of target temperature intervals according to different preset temperature limit values, and determining a corresponding second PWM duty cycle according to each target temperature interval; Step S332, determining a current duty cycle of the first fan according to one of the target temperature intervals selected from all the target temperature intervals and matching the real-time temperature of the first fan; Step S333: obtaining the real-time rotation speed of the first fan according to the current duty cycle of the first fan, and calculating the difference between the real-time rotation speed of the first fan and the preset expected rotation speed to obtain a first rotation speed error parameter; Step S334: adjusting the real-time speed of the first fan to a preset desired speed according to the first speed error parameter.

[0042] In this step, the working state of the first fan is controlled. First, the air inlet temperatures of all the heat dissipation elements and the real-time temperatures of the first fan are summarized to obtain a temperature summary set. Then, the temperature summary set is divided into multiple target temperature intervals according to different preset temperature limit values, and the corresponding second PWM duty cycle is determined according to each target temperature interval. The purpose is to divide temperatures with similar properties into the same temperature interval, so as to more conveniently determine the specific temperature interval in which the real-time temperature of the first fan is located, that is, according to one of the target temperature intervals selected from all the target temperature intervals and matching the real-time temperature of the first fan, the current duty cycle of the first fan is determined. Furthermore, according to the current duty cycle of the first fan, the real-time speed of the first fan is obtained and the corresponding first speed error parameter is determined, so that the real-time speed of the first fan is adjusted to the preset expected speed according to the first speed error parameter.

[0043] It should be noted that the specific division of the third sampling time period needs to be independently selected according to the actual scenario, which will not be elaborated here; there may be many ways to adjust the real-time speed of the first fan to the preset expected speed according to the first speed error parameter in step S334. For example, the normalized calculation formula shown in the aforementioned embodiment can be referred to for calculation, that is, similarly, the first speed error parameter is substituted into the normalized calculation formula for calculation to obtain the preset expected speed. The relevant constant parameter values ​​can be adaptively adjusted according to the specific situation, which will not be elaborated here.

[0044] In one embodiment, in step S330, the purpose of continuously acquiring the air inlet temperature of the heat dissipation element and the real-time temperature of the first fan is to collect relevant data within the third sampling time period multiple times, so that before executing subsequent steps, the multiple sampled data can be averaged filtered, arithmetic averaged, etc. to improve the smoothness of the data. Alternatively, technical personnel in this field can also use other similar methods to pre-process the sampled data, which is not limited here.

[0045] In one embodiment, the corresponding relationship between the target temperature range and the second PWM duty cycle may be, but is not limited to,: ; in, is the second PWM duty cycle, Summarizes the temperatures in the collection for Temperature.

[0046] It should be noted that ~ for A transition interval, within the transition interval, Corresponding The value of can fluctuate up and down according to the specific situation. The fluctuation here refers to taking the previous interval ( ) or take the next interval ( ) The corresponding value of is, similarly, ~ for Another transition zone, The value of can be selected similarly to the above method.

[0047] An embodiment of the present invention, please refer to Figure 7 When the associated parameter group includes the outlet temperature of the heat dissipation element, the real-time temperature of the second fan, and the ambient temperature and humidity of the water cooling unit, step S3 may include but is not limited to steps S340 to S343, wherein the real-time temperature of the second fan may be but is not limited to being characterized by the real-time temperature of the heat dissipation element on the outlet side and the internal temperature and humidity of the water cooling unit.

[0048] Step S340, obtaining the air outlet temperature of the heat dissipation element, the real-time temperature of the second fan, and the ambient temperature and humidity of the water cooling unit; Step S341, determining whether the first state condition and the second state condition are simultaneously established, if so, executing step S342, otherwise controlling the second fan to stop running, wherein the first state condition is that the air outlet temperature of the heat dissipation element is less than or equal to the first preset temperature threshold, and the second state condition is that the ambient temperature of the water cooling unit is less than or equal to the second preset temperature threshold and the ambient humidity of the water cooling unit is greater than or equal to the preset humidity threshold; Step S342, performing an error evaluation on the real-time temperature of the second fan to obtain a second temperature error parameter; Step S343: determine an ideal PWM duty cycle of the second fan based on the second temperature error parameter, and control the second fan to operate at the ideal PWM duty cycle.

[0049] In this step, the working state of the second fan is controlled. First, the outlet temperature of the heat dissipation element, the real-time temperature of the second fan, and the ambient temperature and humidity of the water cooling unit are obtained, and then it is determined whether the outlet temperature of the heat dissipation element and the ambient temperature and humidity of the water cooling unit meet the requirements, that is, it is determined whether the outlet temperature of the heat dissipation element is greater than the preset temperature threshold, whether the ambient temperature of the water cooling unit is less than or equal to the second preset temperature threshold, and whether the internal environmental humidity of the water cooling unit is greater than or equal to the preset humidity threshold. If both are true, it is determined that the first state condition and the second state condition are simultaneously established, indicating that the second fan is in a normal working state at this time, and it can be further temperature-controlled and adjusted. Otherwise, it is indicated that it is not in a normal working state in the current state, and the second fan should be controlled to stop running or even sound an alarm to prevent greater safety hazards. Then, the real-time temperature of the second fan is evaluated for error to obtain a second temperature error parameter, and then the ideal PWM duty cycle of the second fan is determined based on the second temperature error parameter. The ideal PWM duty cycle is the duty cycle adapted to the second fan, and the second fan can be controlled to operate at the ideal PWM duty cycle.

[0050] It should be noted that there may be multiple ways to perform error evaluation on the real-time temperature of the second fan in step S342. For example, after determining an expected temperature value, the real-time temperature of the second fan may be subtracted from the temperature value to obtain a second temperature error parameter. Alternatively, based on a predetermined temperature error coefficient, the temperature error coefficient may be multiplied by the real-time temperature of the second fan to obtain the second temperature error parameter. The temperature error coefficient may be obtained by referring to the configuration parameters of the second fan or based on application experience in actual processes, and is not limited thereto. In step S343, the ideal PWM duty cycle of the second fan may be determined based on the second temperature error parameter, which may be calculated with reference to but not limited to the normalized calculation formula shown in the aforementioned embodiment. Similarly, the second temperature error parameter may be substituted into the normalized calculation formula for calculation to obtain the ideal PWM duty cycle of the second fan. The relevant constant parameter values ​​may be adaptively adjusted according to the specific circumstances, which will not be elaborated herein.
