Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of liquid cooling, and particularly relates to a method and device for detecting health degree of a loss component in a data center and a terminal. BACKGROUND

[0002] At present, with the vigorous development of mobile Internet, cloud computing and big data, data centers supporting mobile Internet, cloud computing and big data are growing explosively, and the performance requirements for server equipment are increasingly high. The reliability of electronic components working under temperature-sensitive characteristics brings severe challenges to traditional air cooling technology with low thermal efficiency. Therefore, liquid cooling technology has gradually become a research hotspot for heat dissipation technology of high-density servers.

[0003] In a liquid cooling system, loss components that need to be regularly inspected, cleaned or replaced are usually provided, such as a filter for filtering cold liquid in the liquid cooling system or a plate heat exchanger provided between a primary side and a secondary side to play a heat exchange role.

[0004] The loss component is prone to blockage after a period of use, affecting the heat dissipation or heat exchange effect, and the blockage condition in the loss component needs to be judged. In related technologies, the actual pressure difference on both sides of the loss component is usually compared with a pressure difference experience value to make a judgment. The pressure difference experience value is determined based on a preset pressure difference when blockage occurs. However, on the one hand, the judgment result based on the experience value is often not accurate, and on the other hand, this method has application limitations and cannot accurately evaluate the blockage condition of the loss component under a variable flow system. For example, when the cold liquid flow in the system becomes larger, the pressure difference on both sides of the loss component will obviously increase, but at this time it cannot be indicated that the loss component has been blocked, so false positives will occur. SUMMARY

[0005] The present application provides a method, device, terminal and computer readable storage medium for detecting health degree of a loss component in a liquid cooling system to solve the problem of inaccurate detection of health degree of a loss component in a liquid cooling system in the prior art.

[0006] In a first aspect, the present application provides a method for detecting health degree of a loss component in a liquid cooling system, comprising:

[0007] obtaining a flow resistance factor target value of a target loss component;

[0008] obtaining a flow resistance factor actual value of the target loss component;

[0009] comparing the flow resistance factor target value and the flow resistance factor actual value to obtain the health degree of the target loss component;

[0010] The flow resistance factor target value represents the flow resistance factor of the target loss component under the condition of rated flow and a preset blocked flow resistance, and the flow resistance factor actual value represents the flow resistance factor of the target loss component under the condition of actual flow and actual pressure difference.

[0011] In a second aspect, the present application provides a device for detecting health degree of a loss component of a liquid cooling system, comprising:

The target value of the flow resistance factor and the actual value of the flow resistance factor of the target loss component are obtained, and then the target value of the flow resistance factor and the actual value of the flow resistance factor are compared to obtain the health degree of the target loss component. The present application first proposes a method for judging health degree by using the flow resistance factor.

It is a dimensionless number and can be expressed as the ratio of the resistance to the dynamic pressure of the fluid. Compared with the existing method for judging the health degree based on the pressure difference at both ends of the loss component, the method for judging the health degree by using the flow resistance factor can more accurately reflect the blocking condition of the liquid cooling system through the loss component, and can also accurately evaluate the blocking condition of the loss component under the variable flow system, thereby improving the accuracy of detecting the health degree of the loss component of the liquid cooling system.

[0025] In the following description, specific details are set forth in order to provide a thorough understanding of embodiments of the present application. However, persons skilled in the art will understand that embodiments of the present application can be practiced without these specific details. In other instances, well-known structures, devices, circuits, and methods have not been described in detail in order to avoid obscuring the present application.

[0026] In order to make the objects, technical solutions, and advantages of the present application clearer, specific embodiments will be described below with reference to the drawings.

[0027] Figure 1 is a schematic diagram of the architecture of a liquid cooling system provided by an embodiment of the present application. As shown in Figure 1 the liquid cooling system includes a primary side and a secondary side, the primary side and the secondary side exchange heat through a plate heat exchanger HE01, and the cold liquid flows in the primary side and the secondary side as shown in Figure 1The primary side is provided with a flow transmitter FT11, pressure transmitters PT11 and PT12 in the direction of the black arrow, the FT11 can be used to measure the cold liquid flow of the primary side, and the PT11 and PT12 can be used to measure the pressure difference between the two ends of the primary side end of the plate heat exchanger HE01 (the related technology judges the blockage of the primary side end of the plate heat exchanger based on the comparison of the pressure difference with the empirical value of the pressure difference). The secondary side is provided with a flow transmitter FT21, a filter FL211, pressure transmitters PT21, PT22 and PT23; FT21 can be used to measure the cold liquid flow of the secondary side, PT22 and PT23 can be used to measure the pressure difference between the two ends of the secondary side end of the plate heat exchanger HE01 (the related technology judges the blockage of the secondary side end of the plate heat exchanger based on the comparison of the pressure difference with the empirical value of the pressure difference), and PT21 and PT22 are used to measure the pressure difference between the two ends of the filter FL211 (the related technology judges the blockage between the two ends of the filter based on the comparison of the pressure difference with the empirical value of the pressure difference).

[0028] Figure 1 The plate heat exchanger HE01 and the filter FL211 shown are prone to blockage after a period of use, affecting the heat dissipation or heat exchange effect, which is referred to as a consumable in the present application. The present application can detect the health of the consumable that may be blocked in the liquid cooling system and thus affect the heat dissipation or heat exchange effect, so as to realize timely cleaning or replacement of the consumable, and protect the heat exchange / heat dissipation performance of the liquid cooling system, which is beneficial to the safe and stable operation of the data center.

[0029] Referring to Figure 2 which shows the implementation flowchart of the method for detecting the health of the consumable of the liquid cooling system provided by the embodiment of the present application, and is described in detail as follows:

[0030] In step 201, the flow resistance factor target value of the target consumable is obtained.

[0031] In the embodiment of the present application, the target consumable can be a filter in the liquid cooling system, or a heat exchanger in the liquid cooling system, which refers to a device that may be blocked in the liquid cooling system and thus affect the heat dissipation or heat exchange effect.

[0032] In the embodiment of the present application, the flow resistance factor is usually used to describe the resistance caused by the friction of the inner wall of the pipeline, the bending of the pipeline, the viscosity of the fluid and other factors when the fluid flows in the pipeline, which is a dimensionless number and can be expressed as the ratio of the resistance to the dynamic pressure of the fluid.

[0033] In the embodiment of the present application, the flow resistance factor target value represents the flow resistance factor of the target loss component under the rated flow and the preset blocked flow resistance condition. The rated flow is the flow of the cooling liquid (fluid) through the target loss component under the standard working condition preset by the liquid cooling system, and the preset blocked flow resistance refers to the flow resistance of the target loss component when it needs to be cleaned or replaced under the rated flow. The value can be obtained through real blocking experiments or simulation blocking experiments on the target loss component, and the preset blocked flow resistance depends on the pipe diameter, pipe length and viscosity coefficient of the fluid. For example, the value of the preset blocked flow resistance can be determined according to the pipe diameter under the blocking state, such as considering that the blocked pipe diameter is half of the normal pipe diameter.

[0034] After determining the preset blocked flow resistance, the rated blocked pressure difference can be obtained according to the formula ΔP h0 = Q0x R0, where R0 represents the preset blocked flow resistance, Q0 represents the rated flow, and ΔP h0 represents the rated blocked pressure difference. Then, the flow resistance factor target value can be calculated according to the rated blocked pressure difference and the fluid dynamic pressure.

[0035] In the embodiment of the present application, since the preset target flow resistance refers to the flow resistance of the target loss component when it needs to be cleaned or replaced under the rated flow, the rated blocked pressure difference calculated based on the preset target flow resistance is also the pressure difference when the target loss component needs to be cleaned or replaced, that is, the flow resistance factor target value represents the flow resistance factor of the target loss component when it needs to be cleaned or replaced. Moreover, compared with the pressure difference empirical value as the comparison object in the related art, the flow resistance factor target value is more objective and accurate, and is not affected by the flow fluctuation, thereby having wider applicability.

[0036] Referring to Figure 3 , an implementation flowchart of step 201 in the method for detecting the health degree of the loss component of the liquid cooling system is shown, as shown in Figure 3 .

[0037] Step 2011, acquiring the rated flow of the target loss component, and determining the rated flow rate according to the rated flow;

[0038] Step 2012, acquiring the preset blocked flow resistance of the target loss component, and determining the rated blocked pressure difference according to the preset blocked flow resistance and the rated flow;

[0039] Step 2013, acquiring the medium density of the cooling liquid in the liquid cooling system;

[0040] Step 2014, obtaining the flow resistance factor target value of the target loss component according to the rated blocked pressure difference, the rated flow rate, the medium density and a preset first calculation formula;

[0041] The first calculation formula includes:

[0042]

[0043] wherein, ξ0 represents a flow resistance factor target value, ΔP h0 represents a rated blockage pressure difference, ρ represents a medium density of the cold liquid, v0 represents a rated flow rate.

[0044] In the embodiment of the present application, the rated flow rate can be determined according to the rated flow of the system, the pipe diameter of the target loss component and the medium density of the cold liquid, for example, obtained based on the calculation method given in the following embodiment. After the preset blockage flow resistance is determined, the rated blockage pressure difference can be obtained according to the formula ΔP h0 = Q0x R0; the flow resistance factor target value can be calculated according to the rated blockage pressure difference and the fluid dynamic pressure, the fluid dynamic pressure of the cold liquid can be calculated according to the medium density of the cold liquid and the rated flow rate, and the rated flow rate can be obtained according to the rated flow divided by the pipe cross-sectional area of the target loss component, which can be calculated based on the pipe diameter. Finally, the rated blockage pressure difference of the target loss component can be obtained by multiplying the preset blockage flow resistance by the rated flow, and the flow resistance factor target value of the target loss component can be determined according to the rated flow rate and the rated blockage pressure difference.

[0045] As can be seen, in the embodiment, since the preset target flow resistance refers to the flow resistance of the target loss component when it needs to be cleaned or replaced under the rated flow, the rated blockage pressure difference calculated based on the preset target flow resistance is also the pressure difference when the target loss component needs to be cleaned or replaced, that is, the flow resistance factor target value represents the flow resistance factor when the target loss component needs to be cleaned or replaced. Compared with the pressure difference empirical value as the comparison object in the related art, the flow resistance factor target value is more objective and accurate, and is not affected by flow fluctuations, and has wider applicability.

[0046] It should be noted that the first calculation formula described above is only a more optimal calculation method of the flow resistance factor, and other methods of calculating the flow resistance factor based on the ratio of the flow resistance or the pressure difference on both sides and the fluid dynamic pressure are also applicable to the present application, and also have higher accuracy and wider applicability compared with the prior art.

[0047] In a further embodiment, the above obtaining the rated flow of the target loss component and determining the rated flow rate according to the rated flow can include:

[0048] obtaining the pipe diameter of the target loss component;

[0049] determining the rated flow rate of the target loss component according to the rated flow, the pipe diameter and a preset flow rate calculation formula;

[0050] wherein, the flow rate calculation formula includes:

[0051]

[0052] wherein Q0 represents the rated flow rate, and D represents the pipe diameter.

[0053] In the embodiment of the present application, the rated flow rate of the target loss component can be calculated by the flow rate calculation formula based on the rated flow rate and the pipe diameter of the target loss component and other system inherent design parameters or inherent physical parameters.

[0054] In step 202, the actual value of the flow resistance factor of the target loss component is obtained.

[0055] In the embodiment of the present application, the actual value of the flow resistance factor of the target loss component represents the flow resistance factor of the target loss component under the actual flow rate and the actual pressure difference.

[0056] In one specific embodiment, the above step 202 can include:

[0057] obtaining the actual pressure difference between the front end and the rear end of the target loss component;

[0058] obtaining the actual flow rate of the cooling liquid in the target loss component;

[0059] obtaining the medium density of the cooling liquid in the liquid cooling system;

[0060] obtaining the actual value of the flow resistance factor of the target loss component according to the actual pressure difference, the actual flow rate, the medium density, and a preset second calculation formula;

[0061] wherein the second calculation formula includes:

[0062]

[0063] wherein ξ1 represents the actual value of the flow resistance factor, v1 the actual flow rate, and ρ represents the medium density of the cooling liquid, ΔP h1 represents the actual pressure difference.

[0064] In actual application, referring to the liquid cooling system shown in Figure 1 the actual flow rate of the primary side can be measured according to the flow transmitter FT11, the actual flow rate of the secondary side can be measured according to the flow transmitter FT21, and the actual flow rate can be calculated according to the actual flow rate and the pipe diameter.

[0065] The actual pressure difference of the filter FL211 can be obtained according to the difference between the measured values of the pressure transmitters PT21 and PT22; the actual pressure difference of the primary side of the plate heat exchanger HE01 can be obtained according to the difference between the measured values of the pressure transmitters PT11 and PT12; and the actual pressure difference of the secondary side of the plate heat exchanger HE01 can be obtained according to the difference between the measured values of the pressure transmitters PT22 and PT23. Thus, the actual values of the flow resistance factors of the filter FL211, the primary side and the secondary side of the plate heat exchanger HE01 can be calculated and obtained.

[0066] In the embodiment of the present application, the actual value of the flow resistance factor is calculated based on the actual pressure difference on both sides of the front and rear ends of the target wearing part, the density of the cold liquid medium, and the actual flow rate, and can truly reflect the fluid resistance condition of the target wearing part under the current working state. The health status of the target wearing part can be determined by comparing the actual value of the flow resistance factor with the target value of the flow resistance factor. For example, when the target wearing part is blocked, the actual value of the flow resistance factor becomes larger. As the actual value of the flow resistance factor gradually becomes larger, the health degree of the target wearing part gradually decreases. When the actual value of the flow resistance factor increases to the target value of the flow rate factor, the health degree is 0, and the target wearing part needs to be cleaned or replaced.

[0067] In step 203, the target value of the flow resistance factor and the actual value of the flow resistance factor are compared to obtain the health degree of the target wearing part.

[0068] In the embodiment of the present application, the health degree of the target wearing part can be obtained by comparing the target value of the flow resistance factor with the actual value of the flow resistance factor. For example, when the target value of the flow resistance factor and the actual value of the flow resistance factor are not greatly different, it can be considered that the health of the target wearing part is not good, and the target wearing part needs to be cleaned or replaced. When the target value of the flow resistance factor is greatly different from the actual value of the flow resistance factor, it can be considered that the health degree of the target wearing part is good.

[0069] In one embodiment, step 203 can specifically include: dividing the actual value of the flow resistance factor by the target value of the flow resistance factor to obtain a wearing ratio; and subtracting the wearing ratio from 1 to obtain the health degree of the target wearing part.

[0070] In the embodiment, the ratio of the actual value of the flow resistance factor to the target value of the flow resistance factor is taken as the wearing ratio, and 1 is subtracted from the wearing ratio to obtain the health degree of the target wearing part. For example, when the target value of the flow resistance factor is 100 and the actual value of the flow resistance factor is 30, the health degree of the target wearing part is 70% (1-30 / 100).

[0071] In another embodiment, step 203 can specifically include: obtaining a plurality of actual values of the flow resistance factor in a preset time length, and calculating a change rate of the actual values of the flow resistance factor; and determining the remaining available time length of the target wearing part according to the target value of the flow resistance factor and the change rate of the actual values of the flow resistance factor.

[0072] In the embodiment, the continuous flow resistance factor actual value can be continuously monitored and calculated in a continuous time period, and a curve of the flow resistance factor actual value changing with time can be generated according to the correspondence between the time and the flow resistance factor actual value, the curve can reflect the change rate of the flow resistance factor actual value, and according to the change rate of the flow resistance factor actual value, it can be known how long the flow resistance factor will reach the flow resistance factor target value, so that the remaining available time length of the target loss component is determined, that is, the life prediction of the target loss component can be realized. For example, the flow resistance factor target value is 100, according to the curve determined by the plurality of flow resistance factor actual values in the preset time period, it is calculated that the change rate of the flow resistance factor actual value is 1 per 12 hours, and then if the current flow resistance factor actual value is 20, it means that the target loss component can still operate normally for 960 hours, and then cleaning and replacement are needed, that is, the life of the target loss component still has 960 hours, that is, 40 days,

[0073] It should be noted that the method of judging the health degree by using the pressure difference between the two ends of the loss component in the related art is affected by the cold liquid flow, and the actual value is irregular, so it is difficult to realize the life prediction of the loss component, and only an inaccurate real-time value can be obtained. The health degree detection based on the flow resistance factor in the present application is not affected by the change of the cold liquid flow, and the health degree is more accurately judged and the life of the loss component is predicted.

[0074] It should be noted that for the plate heat exchanger, since it has two independent flow channels, the health degrees of the primary side and the secondary side need to be calculated respectively, and the two are independent.

[0075] As can be seen from the above, the present application provides a method for detecting the health degree of the loss component of the liquid cooling system, by obtaining the flow resistance factor target value and the flow resistance factor actual value of the target loss component, and then comparing the flow resistance factor target value and the flow resistance factor actual value, the health degree of the target loss component is obtained. The present application first proposes a method for judging the health degree by using the flow resistance factor. The flow resistance factor is usually used to describe the resistance caused by the friction of the inner wall of the pipeline, the bending of the pipeline, the viscosity of the fluid and other factors when the fluid flows in the pipeline, and it is a dimensionless number, which can be expressed as the ratio of the resistance to the fluid dynamic pressure. Compared with the existing technology based on the pressure difference between the two ends of the loss component, the health degree judgment method using the flow resistance factor can more accurately reflect the blocking condition of the cold liquid passing through the loss component, and can also accurately evaluate the blocking condition of the loss component under the variable flow system, thereby improving the accuracy of the health degree detection of the loss component of the liquid cooling system.

[0076] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.

It is a dimensionless number that can be expressed as the ratio of resistance to the dynamic pressure of the fluid. Compared with the existing judgment method based on the pressure difference at both ends of the consumable part, the use of the flow resistance factor to judge the health can more accurately reflect the blockage of the cooling liquid passing through the consumable part. It can also accurately evaluate the blockage of the consumable part in a variable flow system, thereby improving the accuracy of the health detection of the consumable parts of the liquid cooling system.
