[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application 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 application and are not used to limit the present application.

[0040] In one embodiment, Figure 1As shown, a liquid cooling system is provided, including a temperature acquisition module 12, a pressure acquisition module 11, a control center 13 and a liquid supply module 14; the control center 13 is connected to the temperature acquisition module 12, the pressure acquisition module 11 and the liquid supply module 14 respectively;

[0041] The temperature acquisition module 12 is used to collect the temperature information of the monitored device 15 and the coolant temperature of the liquid supply module 14;

[0042] The pressure collection module 11 is used to collect the air pressure information of the monitored device 15;

[0043] The pressure acquisition module 11 further includes a feedback unit, which is used to feedback the pressure acquisition working status of the pressure acquisition module 11;

[0044] The control center 13 is used to perform accuracy detection on the temperature acquisition module 12 based on the air pressure information and the acquired standard environmental parameters;

[0045] The control center 13 is also used to control the liquid supply module 14 to perform liquid cooling on the monitored device 15 based on the temperature information, the air pressure information, the result of the accuracy detection and the pressure collection working status.

[0046] Specifically, the temperature acquisition module 12 is used to collect temperature information at preset collection points in the monitored device 15, wherein the collection points can be set by relevant technical personnel, such as being set at points where the temperature needs to be monitored. Further, the temperature acquisition module 12 can also collect the temperature of the coolant in the liquid supply device, wherein the liquid supply module 14 is a device for providing coolant and flow circuits, generally including general liquid supply devices of liquid cooling systems such as circulating pumps, fans and cold plates. In some preferred embodiments, the liquid cooling processing power of the monitored device 15 can be comprehensively considered based on the temperature information of the monitored device 15 collected by the temperature acquisition module 12 and the coolant temperature of the liquid supply module 14. For example, the liquid cooling power of the liquid cooling system mainly depends on the temperature of the monitored device 15. The higher the temperature of the monitored device 15, the greater the liquid cooling processing power. The coolant temperature in the liquid supply module 14 also affects the liquid cooling processing power difference, because the lower the coolant temperature, the worse the fluidity will be, and the greater the resistance during flow will be, which will cause the device to provide greater power to promote the flow of coolant. However, the driving capacity of the device is limited (i.e., the speed of the circulating pump). At a certain speed, excessive driving current will cause damage to the device (circulating pump) and reduce the life of the equipment. In summary, the temperature of the coolant will determine the upper limit of the liquid cooling processing power, and the temperature of the monitored device 15 will determine the lower limit of the liquid cooling processing power.

[0047] Furthermore, the present embodiment further includes a pressure acquisition module 11, which has an output signal and a feedback signal, and can generally be used for air pressure acquisition in a closed or semi-closed location inside the monitored device 15, as well as ambient air pressure acquisition. In the present embodiment, the pressure acquisition module 11 can acquire air pressure information of the monitored device 15. The pressure acquisition module 11 also includes a feedback unit, which is generally used to output a voltage signal of a certain value or frequency, and can be used to feedback the pressure acquisition working state of the pressure acquisition module 11 itself. The pressure acquisition working state generally includes a normal state, an abnormal state, etc., so that the working state of the pressure acquisition module 11 can be obtained based on the feedback unit. In actual applications, the specific output content and type of the feedback unit can be determined by relevant technical personnel according to actual needs.

[0048] Furthermore, the control center 13 performs an accuracy test on the temperature acquisition module 12 based on the air pressure information and the acquired standard environmental parameters, wherein the air pressure information is the air pressure inside the monitored device 15 during liquid cooling treatment acquired by the pressure acquisition module 11, and the above-mentioned standard environmental parameters are standard environmental parameters preset inside the monitored device 15. In some preferred embodiments, the standard environmental parameters may be the initial environmental parameters inside the monitored device 15, that is, the initial environmental parameters before liquid cooling is performed. The standard environmental parameters include, but are not limited to, standard air pressure, standard temperature, etc. The above-mentioned accuracy detection of the temperature acquisition module 12 is to detect whether the temperature acquisition module 12 is working normally through the temperature information collected by the temperature acquisition module 12. In some preferred embodiments, the accuracy detection method includes but is not limited to calculating the temperature information that the temperature acquisition module 12 should collect under ideal conditions according to the air pressure parameters based on the theoretical formula P1T1=P2T2 under ideal conditions, wherein P1 is the standard air pressure preset in the monitored device 15, P1 can be collected by the pressure acquisition module 11, T1 is the standard temperature preset in the monitored device 15, T1 can be collected by the temperature acquisition module 12, P2 is the air pressure information at the collection point in the monitored device 15 collected by the pressure acquisition module 11 during the liquid cooling process, P1 and T1 are the standard environmental parameters mentioned above, thereby deriving the temperature information T2 that the temperature acquisition module 12 should collect under ideal conditions, that is, the temperature information in the monitored device 15 collected by the temperature acquisition module 12 during the liquid cooling process. If the calculated temperature information T2 under ideal conditions is significantly different from the temperature information actually collected by the temperature acquisition module 12, and the feedback unit in the pressure acquisition module 11 feeds back that the pressure acquisition module 11 is working normally, then the temperature acquisition module 12 is most likely in an abnormal state at this time. Similarly, if the temperature information T2 under ideal conditions is slightly different from the temperature information actually collected by the temperature acquisition module 12, and the feedback unit in the pressure acquisition module 11 feeds back that the pressure acquisition module 11 is working normally, then the temperature acquisition module 12 is most likely in a normal working state at this time. In summary, the accuracy detection of the temperature acquisition module 12 can be achieved. In actual applications, the temperature information T2 under ideal conditions and the temperature information actually collected by the temperature acquisition module 12 are generally not exactly the same, but the difference between the two should be small. The setting of the threshold can be obtained through actual measurement in actual applications.

[0049] Finally, the control center 13 can control the liquid supply module 14 to perform liquid cooling on the monitored equipment 15 based on the temperature information uploaded by the temperature acquisition module 12, the air pressure information uploaded by the pressure acquisition module 11, the accuracy detection result of the temperature acquisition module 12, and the pressure acquisition working status fed back by the feedback unit.

[0050] In summary, the present embodiment can feedback the working status of the pressure acquisition module 11 itself through the feedback unit, and can promptly discover the abnormal situation of the pressure acquisition module 11. Furthermore, the present embodiment can, through the control center 13, combine the air pressure information collected by the pressure acquisition module 11 and the standard environmental parameters to horizontally detect whether the temperature acquisition module 12 is working normally, thereby avoiding the situation where the acquisition module serves as the first failure component and thus causes the entire liquid cooling system to fail to work normally, thereby effectively improving the overall reliability and safety of the liquid cooling system.

[0051] In some embodiments, the liquid supply module further includes at least two-point liquid level switches; wherein the liquid level switches generate a first liquid level signal when the liquid level is lower than the liquid level switches, and generate a second liquid level signal when the liquid level is higher than the liquid level switches.

[0052] Specifically, the liquid supply module includes a multi-point liquid level switch, and the type of liquid level switch to be used can be determined according to the actual application scenario. For example, in some embodiments, a plurality of liquid level switches can be evenly arranged in the liquid storage tank in the liquid supply module, and the plurality of liquid level switches are generally arranged in the liquid supply module in a form perpendicular to the horizontal plane; or, a plurality of liquid level switches can be unevenly arranged in the liquid storage tank according to actual needs, and the arrangement position of the liquid level switch is determined by the shape and placement position of the liquid storage tank, etc.

[0053] In the two different situations where the liquid level is lower than the liquid level switch and the liquid level is higher than the liquid level switch, different liquid level signals will be generated respectively, that is, when the liquid level is lower than the liquid level switch, a first liquid level signal is generated, and when the liquid level is higher than the liquid level switch, a second liquid level signal is generated, and the first liquid level signal and the second liquid level signal are different. In some preferred embodiments, when the liquid level is lower than the liquid level switch, the liquid level switch is disconnected, that is, the first liquid level signal is a disconnection signal; when the liquid level is higher than the liquid level switch, the liquid level switch is turned on, that is, the second liquid level signal is a conduction signal. In summary, when leakage is detected by the liquid level switch, the liquid cooling treatment of the monitored equipment is stopped based on the detection results, the operation of the monitored equipment is stopped, and the alarm processing is performed in a timely manner.

[0054] In some embodiments, the liquid cooling system includes a flow collection module, which is connected to the control center and the liquid supply module respectively:

[0055] The flow acquisition module is used to detect the liquid outflow and return flow of the liquid supply module, and to perform leakage detection on the liquid supply module according to the liquid outflow and return flow, and to feed back the leakage detection results to the control center.

[0056] Specifically, the flow acquisition module is used to detect the liquid outflow and return flow of the liquid supply module. The control center can detect liquid leakage of the liquid supply module based on the liquid outflow and return flow. In actual applications, the control center can detect more obvious leakage based on the collection results of the flow acquisition module. When leakage is detected in the liquid supply module, the liquid cooling system and the monitored equipment are stopped, and an alarm is processed.

[0057] In some of the embodiments, the liquid supply module is used to obtain a liquid cooling control signal sent by a control center, perform liquid cooling on the monitored equipment based on the liquid cooling control signal, and feed back the liquid cooling result to the control center; wherein the liquid cooling result is obtained based at least on the working status of the circulating pump, fan and cold plate in the liquid supply module.

[0058] Specifically, the control center combines the temperature information, the air pressure information, the accuracy detection result and the pressure acquisition working state to generate a liquid cooling control signal, and performs liquid cooling treatment on the monitored equipment based on the liquid cooling control signal, wherein the liquid cooling control signal generally indicates the working state of each component of the liquid supply module, such as the operating power of the circulating pump, the operating power of the fan, etc., and feeds back the liquid cooling result of the monitored equipment to the control center, wherein the liquid cooling result generally includes the temperature information of the monitored equipment after the liquid cooling treatment, the feedback signal of the fan and the circulating pump, etc., wherein the feedback signal of the fan and the pump generally represents the working frequency of the fan and the pump, such as N turns corresponding to the generation of M pulses, etc., and there is a preset mapping relationship between the number of turns and the pulse. In actual applications, the fan and the pump can be controlled to work through the command issued by the control signal, and the control signal is the theoretical value of the fan and pump speed, and then the actual speed of the fan and the circulating pump can be calculated through the above feedback signal, and the theoretical speed is compared with the actual speed. When the error between the two is small, it indicates that the equipment is working normally, wherein the error threshold can be set by relevant technical personnel according to actual needs. Through this embodiment, the liquid cooling system can complete the full process supervision of the liquid cooling treatment of the monitored equipment. In some preferred embodiments, the liquid cooling control signal during the next liquid cooling treatment can be further adjusted through the feedback of the liquid cooling results.

[0059] In some of the embodiments, the pressure acquisition module is also used to acquire the ambient pressure in the standard environmental parameters;

[0060] The temperature acquisition module is also used to collect the ambient temperature in the standard environmental parameters.

[0061] Specifically, the standard environmental parameters mentioned above are the standard environmental parameters preset in the monitored device, namely, P1 (standard air pressure preset in the monitored device) and T1 (standard temperature preset in the monitored device) mentioned above. In some embodiments, the above standard environmental parameters are the initial environmental parameters before liquid cooling treatment.

[0062] In some embodiments, the control center is further used to control the liquid supply module to perform normal liquid cooling on the monitored device when it is detected that the result of the accuracy detection is that the temperature acquisition module is working normally, and the result of the pressure acquisition working state is that the pressure acquisition module is working normally; wherein the normal liquid cooling is to perform liquid cooling on the monitored device according to the temperature information collected by the temperature acquisition module;

[0063] The control center is further used to control the liquid supply module to perform abnormal liquid cooling on the monitored device when it is detected that any one of the pressure acquisition module and the temperature acquisition module fails to work normally; wherein, when the temperature acquisition module works normally, the abnormal liquid cooling is to perform liquid cooling on the monitored device based on the preset temperature compensation parameters and the temperature information collected by the temperature acquisition module, or, when the pressure acquisition module works normally, to perform liquid cooling on the monitored device based on the preset pressure compensation parameters in combination with the pressure and temperature information calculated by the pressure acquisition module according to the air pressure information and the standard environmental parameters;

[0064] The control center is also used to control the liquid supply module to stop liquid cooling the monitored equipment and issue an alarm when it is detected that the pressure acquisition module and the temperature acquisition module fail to work normally.

[0065] Specifically, in the present application, the working status of the temperature acquisition module and the pressure acquisition module can be detected. Specifically, based on the feedback unit in the pressure acquisition module, the working status of the pressure acquisition module itself can be detected. Based on the air pressure information collected by the pressure acquisition module and the acquired standard environmental parameters, the working status of the temperature acquisition module can be horizontally detected.

[0066] When the control center detects that both the temperature acquisition module and the pressure acquisition module are working normally, the liquid supply module is controlled to perform normal liquid cooling on the monitored equipment. In actual applications, when both the temperature acquisition module and the pressure acquisition module are working normally, the temperature parameters collected by the temperature acquisition module are more accurate, while the pressure-temperature information calculated from the air pressure information collected by the pressure acquisition module and the standard environmental parameters is generally not as accurate as the temperature parameters. Therefore, when both acquisition modules are normal, normal liquid cooling is to control the liquid supply module to perform liquid cooling on the monitored equipment based on the temperature parameters collected by the temperature acquisition module.

[0067] When the control center detects that any one of the pressure acquisition module and the temperature acquisition module fails to work properly, the control liquid supply module performs abnormal liquid cooling on the monitored device. Specifically, when it is detected that the temperature acquisition module works properly and the pressure acquisition module is abnormal, the abnormal liquid cooling is to compensate the temperature information collected by the temperature acquisition module based on the preset temperature compensation parameters, and perform liquid cooling on the monitored device according to the compensation results. The preset temperature compensation parameters can be set in advance by relevant technical personnel according to actual needs. For example, simulation can be performed before the actual liquid cooling process, and the above temperature compensation parameters can be calculated according to the simulation results. Similarly, when it is detected that the pressure acquisition module works properly and the temperature acquisition module is abnormal, the pressure and temperature information calculated according to the air pressure information and the standard environmental parameters is compensated according to the preset pressure compensation parameters, and the monitored device is liquid cooled according to the compensation results. Similarly, the pressure compensation parameters can also be set in advance by relevant technical personnel according to actual needs.

[0068] In some preferred embodiments, when the temperature acquisition module works normally and the pressure acquisition module is abnormal, the abnormal liquid cooling process is to multiply the preset temperature weight by the temperature information, and perform liquid cooling on the monitored device according to the calculation result, wherein the temperature weight is generally greater than 1. When the pressure acquisition module works normally and the temperature acquisition module is abnormal, the abnormal liquid cooling process is to multiply the preset pressure weight by the pressure and temperature information calculated according to the air pressure information and the standard environmental parameters, and perform liquid cooling on the monitored device according to the calculation result, wherein the pressure weight is generally greater than 1. Based on the present application, it can be understood by those skilled in the art that when any of the two acquisition modules is abnormal, it means that the reliability of the air pressure information and temperature information collected at this time is reduced. At this time, in order to ensure an effective liquid cooling effect on the monitored device, the power of the liquid cooling process needs to be increased to avoid the inability to effectively cool the monitored device due to inaccurate collected temperature information or pressure information, or even cause the monitored device to be overheated and damaged.

[0069] In some of the embodiments, the control center is also used to control the liquid supply module to stop liquid cooling of the monitored equipment and issue an alarm when leakage is detected in the liquid supply module through the liquid level switch and / or the flow acquisition module.

[0070] Specifically, if the liquid supply module is detected to be leaking through the liquid level switch or the flow acquisition module, the liquid supply module is controlled to stop the liquid cooling process for the monitored device and an alarm is issued. In some preferred embodiments, after completing the detection of whether the temperature acquisition module and the pressure acquisition module are working properly, the liquid supply module is detected to be leaking through the liquid level switch and the flow acquisition module. If a liquid leakage is detected, the liquid cooling process for the monitored device is stopped and an alarm is issued.

[0071] This embodiment also provides a preferred embodiment of a liquid cooling system. Figure 2 FIG. 4 is a schematic diagram of the structure of a liquid cooling system in a preferred embodiment.

[0072] The present embodiment includes a pressure acquisition module 11, a control center 13, a temperature acquisition module 12, a liquid level switch 22, a liquid supply module 14 and a flow acquisition module 21, and the monitored device 15 is connected to the temperature acquisition module 12 and the pressure acquisition module 11 respectively. Among them, the monitored device 15 is a device that needs to be monitored and the temperature is maintained by liquid cooling; the pressure acquisition module 11 has an output signal and a feedback signal, which can complete the air pressure acquisition of a closed or semi-closed part of the monitored device 15 and the air pressure acquisition of the external environment, wherein the feedback signal is generated by the feedback unit inside the pressure acquisition module 11; the temperature acquisition module 12 is used to collect the temperature information inside the monitored device 15, the coolant temperature information in the liquid supply module 14, and the external environment temperature information; the control center 13 is used to receive the temperature information of each acquisition module The various information collected is used to adjust the liquid supply module 14 to perform liquid cooling on the monitored equipment 15; the liquid supply module 14 is a device for providing cooling liquid and a flow circuit, including a general liquid supply device for a liquid cooling system such as a circulating pump, a fan and a cold plate; the flow collection module 21 is used to collect the liquid outlet flow and the liquid return flow of the liquid supply module 14, so as to monitor the more obvious leakage of the liquid supply module 14; wherein, a multi-point liquid level switch 22 is also provided in the liquid supply module 14, and the liquid level switch 22 can timely monitor slow and inconspicuous leakage.

[0073] In actual application, the pressure acquisition module 11 acquires the air pressure information and standard air pressure information in the monitored device 15, and the temperature acquisition module 12 acquires the temperature information, standard temperature information and coolant temperature information of the detected device, and performs self-test processing, specifically including detecting whether the pressure acquisition module 11 is working normally through the feedback unit, detecting whether the temperature acquisition module 12 is working normally through the air pressure information, standard temperature information and standard air pressure information, if it is detected that both acquisition modules are normal, then the liquid supply module 14 is controlled to perform normal liquid cooling pretreatment on the monitored device 15, if it is detected that one of the acquisition modules is abnormal, then the liquid supply module 14 is controlled to perform abnormal liquid cooling pretreatment on the monitored device 15, if it is detected that both acquisition modules are abnormal, then the liquid cooling treatment is stopped and an alarm is sounded. After the pressure acquisition module 11 and the temperature acquisition module 12 are detected, the liquid level switch 22 and the flow acquisition module 21 are used to detect whether there is a leakage in the liquid supply module 14, if a leakage is detected, the liquid supply treatment is stopped and an alarm is sounded, if there is no leakage, then the normal liquid cooling treatment or abnormal liquid cooling treatment is performed accordingly.

[0074] It should be understood that, although each structure in the structure diagram involved in each embodiment as described above is displayed in sequence according to the indication of the arrow, these structures are not necessarily executed in sequence according to the order indicated by the arrow. Unless there is a clear explanation in this article, the execution of these structures does not have a strict order restriction, and these structures can be executed in other orders.

[0077] Step S310, acquiring the temperature information of the monitored device collected by the temperature collection module, the coolant temperature of the liquid supply module, the air pressure information of the monitored device collected by the pressure collection module, and the pressure collection working state of the pressure collection module collected by the feedback unit in the pressure collection module;

[0078] Step S320, performing accuracy detection on the temperature acquisition module according to the air pressure information and the standard environmental parameters acquired by the pressure acquisition module;

[0079] Step S330, controlling the liquid supply module to perform liquid cooling on the monitored device according to the temperature information, the air pressure information, the accuracy detection result and the pressure collection working status.

[0080] In some embodiments, the method further comprises:

[0081] When it is detected that the pressure acquisition module and the temperature acquisition module are both operating normally, the liquid supply module is controlled to perform normal liquid cooling on the monitored equipment;

[0082] When it is detected that any one of the pressure acquisition module and the temperature acquisition module fails to work normally, the liquid supply module is controlled to perform abnormal liquid cooling on the monitored equipment;

[0083] When it is detected that both the pressure acquisition module and the temperature acquisition module fail to work properly, and / or when it is detected that the liquid supply module is leaking, the liquid supply module is controlled to stop liquid cooling of the monitored device and an alarm is issued.

[0085] Acquire temperature information collected by the temperature acquisition module and pressure information collected by the pressure acquisition module; then detect whether the temperature acquisition module works normally, and detect whether the pressure acquisition module works normally;

[0086] If it is detected that both the temperature acquisition module and the pressure acquisition module are normal, the liquid supply module is further detected to see if there is any leakage. If there is no leakage, the liquid supply module is controlled to perform normal liquid cooling on the monitored equipment; if it is detected that there is leakage in the liquid supply module, the liquid supply process is stopped and an alarm is issued;

[0087] If the temperature acquisition module is detected to be abnormal and the pressure acquisition module is normal, the alarm information of the temperature acquisition module abnormality is output, and when it is detected that there is no leakage in the liquid supply module, the liquid supply module is controlled to perform abnormal liquid cooling on the monitored equipment;
