Description

Technical Field

[0001] The present invention relates to the technical field of liquid cooling systems, and in particular to a liquid cooling system and a liquid cooling system control method. Background Art

[0002] Existing liquid cooling equipment usually uses a single liquid pump system, which is installed at the bottom or top of the equipment to pressurize the liquid to flow to each server. The single liquid pump system has the following problems: 1. The single liquid pump system delivers liquid to multiple server liquid pipes through a manifold, which can only achieve a switch function. The liquid inlet pressures of the bottom and top server liquid pipes are different, and the heat dissipation effect is uneven. 2. N liquid pump systems are one-to-one for N servers, and the cost of adjusting the heat dissipation power is high. 3. The heat dissipation power cannot be adjusted according to the server temperature or the temperature of the liquid in the pipeline.

[0003] Therefore, a more optimized liquid cooling system needs to be considered. Summary of the invention

[0004] A first object of the present invention is to provide a liquid cooling system which can improve the heat dissipation uniformity of multiple cooling pipelines and reduce the heat dissipation cost.

[0005] A second object of the present invention is to provide a liquid cooling system control method that can improve the heat dissipation uniformity of multiple cooling pipelines and reduce the heat dissipation cost.

[0006] In order to achieve the above-mentioned first purpose, the liquid cooling system provided by the present invention includes a controller, a manifold, two or more liquid inlet pipelines and three or more cooling pipelines for cooling the cooling target, the liquid outlet of the liquid inlet pipeline and the liquid inlet of the cooling pipeline are both connected to the solution chamber of the manifold, the number of liquid inlet pipelines is less than the number of cooling pipelines, and the liquid inlet of each liquid inlet pipeline is provided with a hydraulic pump, and the liquid inlet of each cooling pipeline is provided with a pressure monitoring device, and the hydraulic pump and the pressure monitoring device are both electrically connected to the controller; the controller is used to control the hydraulic pump to adjust the flow rate according to the pressure values ​​obtained by each pressure monitoring device, so that the hydraulic pressure of the liquid inlets of all cooling pipelines is in an isobaric state.

[0007] It can be seen from the above scheme that the liquid cooling system of the present invention is provided with a manifold, two or more liquid inlet pipelines and three or more cooling pipelines for cooling the cooling target. At the same time, a controller is used to control the hydraulic pump to adjust the flow rate according to the pressure value obtained by the pressure monitoring device, so that the hydraulic pressure of the liquid inlet of all cooling pipelines is in an isobaric state, so that the cooling pipeline can be hydraulically controlled by using hydraulic pumps less than the number of cooling pipelines, so that the hydraulic pressure of all cooling pipelines is in an isobaric state, thereby improving the uniformity of heat dissipation, and compared with the method of setting N liquid pumps to dissipate heat for N servers one-to-one, the heat dissipation cost can be reduced.

[0008] In a further solution, the cooling pipeline is provided with a temperature sensor for detecting the temperature of the liquid in the cooling pipeline and a control valve for controlling the flow rate of the liquid in the cooling pipeline, and both the temperature sensor and the control valve are electrically connected to the controller.

[0009] It can be seen that by arranging a temperature sensor and a control valve in the cooling pipeline, the liquid discharge speed of the liquid pump outlet can be adjusted according to the required heat dissipation degree, thereby improving the adjustment accuracy of the heat dissipation power.

[0010] In a further solution, the temperature sensor includes a first temperature sensor and a second temperature sensor, the first temperature sensor is used to detect the inlet temperature of the cooling pipeline near the liquid inlet, and the second temperature sensor is used to detect the outlet temperature of the cooling pipeline near the liquid outlet.

[0011] It can be seen that the first temperature sensor and the second temperature sensor are used to detect the inlet temperature near the inlet and the outlet temperature near the outlet in the cooling pipeline, which can facilitate the heat dissipation and further control the opening of the control valve.

[0012] In a further solution, the control valve is installed at the liquid outlet of the cooling pipeline.

[0013] It can be seen from this that installing the control valve at the liquid outlet of the cooling pipeline can facilitate disassembly and assembly.

[0014] In a further solution, the liquid outlets of more than two liquid inlet pipelines are evenly arranged on the first side of the manifold, more than three cooling pipelines are evenly arranged on the second side of the manifold, and the first side of the manifold and the second side of the manifold are arranged opposite to each other.

[0015] It can be seen that the liquid outlet of the liquid inlet pipeline is evenly arranged on the first side of the manifold, and the liquid inlet of the cooling pipeline is evenly arranged on the second side of the manifold, and the first side of the manifold and the second side of the manifold are relatively arranged, which can facilitate the adjustment of the influence of the hydraulic pressure of the liquid outlet of the liquid inlet pipeline on the liquid inlet of the cooling pipeline.

[0016] In order to achieve the above-mentioned second purpose, the liquid cooling system control method provided by the present invention includes: controlling all hydraulic pumps to supply liquid to the solution chamber of the manifold; obtaining the pressure value obtained by each pressure monitoring device; and controlling the hydraulic pump to adjust the flow rate according to multiple pressure values ​​so that the hydraulic pressure at the liquid inlet of all cooling pipelines is in an isobaric state.

[0017] It can be seen that the liquid cooling system control method of the present invention obtains the pressure value of the liquid inlet of all cooling pipelines when controlling all hydraulic pumps to supply liquid to the solution chamber of the manifold, and controls the hydraulic pump to adjust the flow rate according to the pressure value, so that the hydraulic pressure of the liquid inlet of all cooling pipelines is in an isobaric state, thereby realizing the use of hydraulic pumps less than the number of cooling pipelines to hydraulically control the cooling pipelines, so that the hydraulic pressure of all cooling pipelines is in an isobaric state, thereby improving the uniformity of heat dissipation, and compared with the method of setting N liquid pumps to dissipate heat for N servers one-to-one, it can reduce the heat dissipation cost.

[0018] In a further scheme, the step of controlling the hydraulic pump to adjust the flow rate according to multiple pressure values ​​so that the hydraulic pressure of the liquid inlets of all cooling pipelines is in an isobaric state includes: determining whether the hydraulic pressure of the liquid inlet of the preset first cooling pipeline is within a preset pressure range, and if so, adjusting the hydraulic pressure of the liquid inlets of the remaining cooling pipelines in sequence according to a preset adjustment order.

[0019] It can be seen from this that when controlling the hydraulic pump to adjust the flow rate according to the pressure value to control the hydraulic pressure of the liquid inlets of all cooling pipes, it is necessary to first confirm that the hydraulic pressure of the liquid inlet of the first cooling pipe reaches the preset pressure range, and then adjust the hydraulic pressure of the liquid inlets of the remaining cooling pipes in turn according to the preset adjustment order, so as to facilitate the hydraulic pressure of the liquid inlets of all cooling pipes.

[0020] In a further scheme, the step of controlling the hydraulic pump to adjust the flow rate according to multiple pressure values ​​so that the hydraulic pressure of the inlets of all cooling pipelines is in an isobaric state also includes: confirming the hydraulic pump corresponding to the outlet of the inlet pipeline closest to the inlet of the current cooling pipeline, and preferentially controlling the hydraulic pump to perform hydraulic adjustment on the current cooling pipeline.

[0021] It can be seen that when the hydraulic pressure of the liquid inlet of the cooling pipeline is adjusted, the hydraulic pump corresponding to the liquid outlet closest to the current liquid inlet of the cooling pipeline is adjusted. Since the liquid outlet closest to the current liquid inlet of the cooling pipeline has the greatest impact, the adjustment speed can be increased.

[0022] In a further scheme, the cooling pipeline is provided with a temperature sensor for detecting the temperature of the liquid in the cooling pipeline and a control valve for controlling the flow rate of the liquid in the cooling pipeline; after the step of controlling all hydraulic pumps to supply liquid to the solution chamber of the manifold, it also includes: obtaining the temperature change of the liquid temperature in each cooling pipeline within a preset time, and adjusting the opening of the control valve according to the temperature change.

[0023] It can be seen from this that the opening of the corresponding control valve is adjusted according to the temperature change of the liquid temperature in each cooling pipeline within the preset time, so that the liquid discharge speed of the liquid pump outlet can be adjusted according to the required heat dissipation level, thereby improving the adjustment accuracy of the heat dissipation power.

[0024] In a further scheme, the step of adjusting the opening of the control valve according to the temperature change includes: when the temperature change is greater than the upper limit value of the first preset threshold range, increasing the opening of the control valve by the preset opening adjustment amount; when the temperature change is within the first preset threshold range, maintaining the current opening of the control valve; when the temperature change is less than the lower limit value of the first preset threshold range, reducing the opening of the control valve by the preset opening adjustment amount.

[0025] It can be seen that by judging the range of the temperature change, the current opening of the valve is controlled and regulated to improve the accuracy of heat dissipation regulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Liquid cooling system example:

[0032] like Figure 1 As described, in this embodiment, the liquid cooling system includes a controller (not shown), a manifold 1, two or more liquid inlet pipelines 2 and three or more cooling pipelines 3 for cooling the target to be cooled. The liquid outlet of the liquid inlet pipeline 2 and the liquid inlet of the cooling pipeline 3 are both connected to the solution chamber 11 of the manifold 1. The number of liquid inlet pipelines 2 is less than the number of cooling pipelines 3. The liquid inlet of each liquid inlet pipeline 2 is provided with a hydraulic pump 4, and the liquid inlet of each cooling pipeline 3 is provided with a pressure monitoring device 5. The hydraulic pump 4 and the pressure monitoring device 5 are both electrically connected to the controller. The target to be cooled can be a heat dissipating device. In this embodiment, the target to be cooled is a server. The cooling pipeline 3 is used to exchange heat with the target to be cooled, so as to achieve the purpose of dissipating heat from the target to be cooled. Preferably, all cooling pipelines 3 have the same length and inner diameter.

[0033] The liquid outlets of more than two liquid inlet pipelines 2 are evenly arranged on the first side of the manifold 1, and more than three cooling pipelines 3 are evenly arranged on the second side of the manifold 1, and the first side of the manifold 1 and the second side of the manifold 1 are arranged oppositely. In this embodiment, the liquid outlets of more than two liquid inlet pipelines 2 are evenly arranged on the first side of the manifold 1 along the plumb direction, and more than three cooling pipelines 3 are evenly arranged on the second side of the manifold 1 along the plumb direction. By evenly arranging the liquid outlets of the liquid inlet pipelines 2 on the first side of the manifold 1, and evenly arranging the liquid inlets of the cooling pipelines 3 on the second side of the manifold 1, and the first side of the manifold 1 and the second side of the manifold 1 are arranged oppositely, it is easy to adjust the influence of the hydraulic pressure of the liquid outlet of the liquid inlet pipeline 2 on the liquid inlet of the cooling pipeline 3.

[0034] The cooling pipeline 3 is provided with a temperature sensor 6 for detecting the temperature of the liquid in the cooling pipeline 3 and a control valve 7 for controlling the flow rate of the liquid in the cooling pipeline 3. The temperature sensor 6 and the control valve 7 are both electrically connected to the controller. In this embodiment, the temperature sensor 6 includes a first temperature sensor 61 and a second temperature sensor 62. The first temperature sensor 61 is used to detect the inlet temperature of the cooling pipeline 3 near the liquid inlet, and the second temperature sensor 62 is used to detect the outlet temperature of the cooling pipeline 3 near the liquid outlet. By arranging the temperature sensor 6 and the control valve 7 in the cooling pipeline 3, the outlet speed of the liquid pump outlet can be adjusted according to the required heat dissipation, thereby improving the adjustment accuracy of the heat dissipation power. The heat dissipation can be obtained by the difference between the temperatures obtained by the first temperature sensor 61 and the second temperature sensor 62 within a preset time.

[0035] In this embodiment, the control valve 7 is installed at the liquid outlet of the cooling pipeline 3. By installing the control valve 7 at the liquid outlet of the cooling pipeline 3, it is easy to disassemble and assemble.

[0036] In order to better illustrate the present invention, the control method of the liquid cooling system is described in detail below.

[0037] See also Figure 2 In this embodiment, when the liquid cooling system control method is working, step S1 is first executed to control all hydraulic pumps 4 to supply liquid to the solution chamber 11 of the manifold 1. In order to dissipate the heat of the target to be cooled, it is necessary to control all hydraulic pumps 4 to supply liquid to the solution chamber 11 of the manifold 1, and then divide the flow through the cooling pipeline 3 connected to the manifold 1, so as to exchange heat with the target to be cooled corresponding to each cooling pipeline 3. Preferably, the cooling liquid used in the liquid cooling system is water.

[0038] After controlling all hydraulic pumps 4 to supply liquid to the solution chamber 11 of the manifold 1, execute step S2 to obtain the pressure value obtained by each pressure monitoring device 5. In order to make the heat dissipation of each target to be cooled uniform and easy to adjust and control, it is necessary to control the pressure of the liquid inlet of each cooling pipeline 3 to be in a balanced pressure state. Therefore, it is necessary to monitor the pressure value of the liquid inlet of each cooling pipeline 3 through the pressure monitoring device 5 so as to control the hydraulic pump 4 to adjust the pressure. The balanced pressure state means that the hydraulic pressure at the liquid inlet of each cooling pipeline 3 is within a preset pressure range, and the preset pressure range can be set according to the pressure required when the cooling pipeline 3 is dissipating heat.

[0039] After obtaining the pressure value obtained by each pressure monitoring device 5, step S3 is executed to control the hydraulic pump 4 to adjust the flow rate according to the multiple pressure values, so that the hydraulic pressure of the liquid inlet of all cooling pipelines 3 is in an isobaric state. Through the pressure value of each pressure monitoring device 5, the hydraulic pressure that needs to be adjusted at the liquid inlet of each cooling pipeline 3 can be determined, so that the corresponding hydraulic pump 4 can be controlled to adjust the flow rate. Preferably, when controlling the hydraulic pump 4 to adjust the flow rate according to multiple pressure values, the liquid flow rate of each hydraulic pump 4 can be PID controlled according to the pressure value.

[0040] In this embodiment, see Figure 3 , when the hydraulic pump 4 is controlled to adjust the flow rate according to multiple pressure values ​​so that the hydraulic pressure of the liquid inlet of all cooling pipelines 3 is in an isobaric state, step S31 is executed to determine whether the hydraulic pressure of the liquid inlet of the preset first cooling pipeline is within the preset pressure range. In order to facilitate the hydraulic adjustment of all cooling pipelines 3, it is necessary to first confirm that the hydraulic pressure of the liquid inlet of the preset first cooling pipeline reaches the preset pressure range. The preset first cooling pipeline is the first cooling pipeline 3 whose liquid inlet is located at the head end or tail end of the manifold 1.

[0041] If the hydraulic pressure of the preset first cooling pipeline inlet is not within the preset pressure range, then continue to execute step S31 for continuous detection. When the hydraulic pressure of the preset first cooling pipeline inlet is not within the preset pressure range, execute step S32 to sequentially adjust the hydraulic pressure of the remaining cooling pipelines 3 in the preset adjustment sequence. First, confirm that the hydraulic pressure of the preset first cooling pipeline 3 inlet reaches the preset pressure range, and then sequentially adjust the hydraulic pressure of the remaining cooling pipelines 3 in the preset adjustment sequence, so as to facilitate the hydraulic pressure of the inlets of all cooling pipelines 3. In this embodiment, the preset adjustment sequence can be to sequentially adjust the hydraulic pressure of the cooling pipeline 3 in the direction from the head end to the tail end of the manifold 1.

[0042] In this embodiment, the step of controlling the hydraulic pump 4 to adjust the flow rate according to multiple pressure values ​​so that the hydraulic pressure of the liquid inlets of all cooling pipelines 3 is in an isobaric state also includes: confirming the hydraulic pump 4 corresponding to the outlet of the liquid inlet pipeline 2 closest to the liquid inlet of the current cooling pipeline 3, and preferentially controlling the hydraulic pump 4 to adjust the hydraulic pressure of the current cooling pipeline 3. When adjusting the hydraulic pressure of the liquid inlet of the cooling pipeline 3, the hydraulic pump 4 corresponding to the outlet closest to the liquid inlet of the current cooling pipeline 3 is adjusted, because the outlet closest to the current cooling pipeline 3 has the greatest influence on the liquid inlet of the current cooling pipeline 3, thereby improving the adjustment speed.

[0043] In this embodiment, see Figure 4 After executing step S1 to control all hydraulic pumps 4 to supply liquid to the solution chamber 11 of the manifold 1, step S4 is also executed to obtain the temperature change of the liquid temperature in each cooling pipeline 3 within a preset time. The preset time can be preset according to experimental data. In order to facilitate the control of the heat dissipation of each target to be cooled, it is necessary to obtain the temperature change of the liquid temperature in each cooling pipeline 3 within the preset time. The temperature change can be determined by the difference between the temperatures obtained by the first temperature sensor 61 and the second temperature sensor 62.

[0044] After the temperature variation is obtained, step S5 is executed to adjust the opening of the control valve 7 according to the temperature variation. The opening of the corresponding control valve 7 is adjusted according to the temperature variation of the liquid temperature in each cooling pipeline 3 within a preset time, so that the liquid outlet speed of the liquid pump outlet can be adjusted according to the required heat dissipation, thereby improving the adjustment accuracy of the heat dissipation power.

[0045] In this embodiment, the step of adjusting the opening of the control valve 7 according to the temperature variation includes: when the temperature variation is greater than the upper limit of the first preset threshold range, increasing the opening of the control valve 7 by the preset opening adjustment amount; when the temperature variation is within the first preset threshold range, maintaining the current opening of the control valve 7; when the temperature variation is less than the lower limit of the first preset threshold range, reducing the opening of the control valve 7 by the preset opening adjustment amount. By judging the range of the temperature variation, the current opening of the control valve 7 is controlled and adjusted to improve the accuracy of heat dissipation adjustment.

[0046] From the above, it can be seen that the liquid cooling system of the present invention is provided with a manifold 1, more than two liquid inlet pipelines 2 and more than three cooling pipelines 3 for cooling the cooling target. At the same time, a controller is used to control the hydraulic pump 4 to adjust the flow rate according to the pressure value obtained by the pressure monitoring device 5, so that the hydraulic pressure of the liquid inlet of all cooling pipelines 3 is in an isobaric state, so that the cooling pipeline 3 can be hydraulically controlled by using hydraulic pumps 4 less than the number of cooling pipelines 3, so that the hydraulic pressure of all cooling pipelines 3 is in an isobaric state, thereby improving the uniformity of heat dissipation and reducing the heat dissipation cost. The liquid cooling system control method of the present invention obtains the pressure values ​​of the liquid inlets of all cooling pipelines 3 when controlling all hydraulic pumps 4 to supply liquid to the solution chamber 11 of the manifold 1, and controls the hydraulic pumps 4 to adjust the flow rate according to multiple pressure values, so that the hydraulic pressures of the liquid inlets of all cooling pipelines 3 are in an isobaric state, thereby achieving hydraulic control of the cooling pipelines 3 using hydraulic pumps 4 less than the number of cooling pipelines 3, so that the hydraulic pressures of all cooling pipelines 3 are in an isobaric state, thereby improving the uniformity of heat dissipation, and reducing the heat dissipation cost compared to the method of setting N liquid pumps to dissipate heat for N servers one-to-one.

[0047] It should be noted that the above are only preferred embodiments of the present invention, but the design concept of the invention is not limited thereto, and any non-substantial modifications made to the present invention using this concept also fall within the protection scope of the present invention.
