Description

A method, device and terminal for detecting health of consumable parts in a data center

Technical Field

The present invention belongs to the field of liquid cooling technology, and in particular relates to a method, a device and a terminal for detecting the health of consumable parts in a data center.

Background technique

At present, with the vigorous development of mobile Internet, cloud computing and big data, the data centers supporting mobile Internet, cloud computing and big data are growing explosively, and the performance requirements for server equipment are getting higher and higher. The reliability of electronic components is sensitive to temperature, which brings severe challenges to the traditional low thermal efficiency air cooling technology. Therefore, liquid cooling technology has gradually become a hot spot in the research of heat dissipation technology for high-density servers.

The liquid cooling system is usually equipped with consumable parts that need to be regularly inspected, cleaned or replaced, such as a filter for filtering the cooling liquid in the liquid cooling system, or a plate heat exchanger provided between the primary side and the secondary side for heat exchange.

After a period of use, the loss parts are prone to blockage, which affects the heat dissipation or heat exchange effect. It is necessary to judge the blockage situation in the loss parts. In the related technology, the actual pressure difference on both sides of the loss parts is usually compared with an empirical value of the pressure difference. The empirical value of the pressure difference is determined based on the preset pressure difference when the blockage occurs. However, on the one hand, the judgment results based on the empirical value are often not accurate enough. On the other hand, this method has application limitations and cannot accurately evaluate the blockage situation of loss parts in variable flow systems. For example, when the flow rate of coolant in the system increases, the pressure difference on both sides of the loss parts will increase significantly, but this does not indicate that the loss parts are blocked, so false alarms will occur.

Summary of the invention

The present invention provides a method, device, terminal and computer-readable storage medium for detecting the health of consumable parts of a liquid cooling system, so as to solve the problem of inaccurate health detection of consumable parts of a liquid cooling system in the prior art.

In a first aspect, the present invention provides a method for detecting the health of consumable parts of a liquid cooling system, comprising:

Obtaining a target value of a flow resistance factor of a target loss component;

Obtaining the actual value of the flow resistance factor of the target loss component;

Compare the target value of the flow resistance factor with the actual value of the flow resistance factor to obtain the health of the target loss component;

The flow resistance factor target value represents the flow resistance factor of the target loss component under the conditions of rated flow and preset blocking flow resistance, and the flow resistance factor actual value represents the flow resistance factor of the target loss component under the conditions of actual flow and actual pressure difference.

In a second aspect, the present invention provides a device for detecting the health of consumable parts of a liquid cooling system, comprising:

A first acquisition unit, used to acquire a target value of a flow resistance factor of a target loss component;

A second acquisition unit, used to acquire an actual value of a flow resistance factor of a target loss component;

A health determination unit, used for comparing the target value of the flow resistance factor with the actual value of the flow resistance factor to obtain the health of the target loss component;

The flow resistance factor target value represents the flow resistance factor of the target loss component under the conditions of rated flow and preset blocking flow resistance, and the flow resistance factor actual value represents the flow resistance factor of the target loss component under the conditions of actual flow and actual pressure difference.

In a third aspect, the present invention provides a terminal comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the method described in the first aspect when executing the computer program.

In a fourth aspect, the present invention provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the method described in the first aspect are implemented.

The present invention provides a method, device, terminal and storage medium for detecting the health of consumable parts in a liquid cooling system. The health of the target consumable part is obtained by obtaining the flow resistance factor target value and the flow resistance factor actual value of the target consumable part, and then comparing the flow resistance factor target value and the flow resistance factor actual value. The present invention proposes for the first time a method for judging the health of the target consumable part 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. 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 judgment method based on the pressure difference at both ends of the consumable part in the prior art, 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 the variable flow system, thereby improving the accuracy of the health detection of the consumable part of the liquid cooling system.

Detailed ways

In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

Fig. 1 is a schematic diagram of the structure of a liquid cooling system provided by an embodiment of the present invention. As shown in Fig. 1, the liquid cooling system includes a primary side and a secondary side, and the primary side and the secondary side perform heat exchange through a plate heat exchanger HE01. The flow direction of the cold liquid on the primary side and the secondary side is shown in the direction of the black arrow in Fig. 1. The primary side is provided with a flow transmitter FT11, and pressure transmitters PT11 and PT12. FT11 can be used to measure the cold liquid flow on the primary side, and PT11 and PT12 can be used to measure the pressure difference between the two ends of the primary side of the plate heat exchanger HE01 (the related technology is based on the comparison of the pressure difference with the pressure difference experience value to judge the blockage of the primary side of the plate heat exchanger). The secondary side is provided with a flow transmitter FT21, a filter FL211, and pressure transmitters PT21, PT22 and PT23; FT21 can be used to measure the cold liquid flow on the secondary side, PT22 and PT23 can be used to measure the pressure difference at both ends of the secondary side of the plate heat exchanger HE01 (the related technology judges the blockage of the secondary side of the plate heat exchanger based on the comparison of the pressure difference with the pressure difference experience value), and PT21 and PT22 are used to measure the pressure difference at both ends of the filter FL211 (the related technology judges the blockage of both ends of the filter based on the comparison of the pressure difference with the pressure difference experience value).

The plate heat exchanger HE01 and filter FL211 shown in FIG1 are prone to blockage after a period of use, which affects the heat dissipation or heat exchange effect. They are referred to as consumable parts in the present invention. The present invention can perform health detection on consumable parts in the liquid cooling system that may cause blockage and thus affect the heat dissipation or heat exchange effect, thereby achieving timely cleaning or replacement of consumable parts, ensuring the heat exchange/heat dissipation performance of the liquid cooling system, and facilitating the safe and stable operation of the data center.

Referring to FIG. 2 , it shows a flowchart of a method for detecting the health of consumable parts of a liquid cooling system provided by an embodiment of the present invention, which is described in detail as follows:

In step 201, a target value of a flow resistance factor of a target loss component is obtained.

In the embodiment of the present invention, the target loss component may be a filter in the liquid cooling system or a heat exchanger in the liquid cooling system, which refers to a component in the liquid cooling system that may be blocked and thus affect the heat dissipation or heat exchange effect.

In the embodiments of the present invention, the flow resistance factor is generally used to describe the resistance caused by friction of the inner wall of the pipeline, pipeline bending, fluid viscosity and other factors when the fluid flows in the pipeline. It is a dimensionless number and can be expressed as the ratio of the resistance to the dynamic pressure of the fluid.

In an embodiment of the present invention, the target value of the flow resistance factor represents the flow resistance factor of the target loss component under the conditions of rated flow and preset blocking flow resistance. The rated flow is the flow of cold liquid (fluid) passing through the target loss component under the preset standard working state of the liquid cooling system, and the preset blocking flow resistance refers to the flow resistance when the target loss component is blocked under the preset rated flow and needs to be cleaned or replaced. This value can be obtained by performing a real blocking experiment or a simulated blocking experiment on the target loss component. The preset blocking flow resistance depends on the pipe diameter, pipe length, and viscosity coefficient of the fluid of the target loss component. Exemplarily, the value of the preset blocking flow resistance can be determined based on the pipe diameter in the blocked state, for example, the blocked pipe diameter is considered to be half of the normal pipe diameter.

After determining and setting the blocking flow resistance, the rated blocking pressure difference can be obtained according to the formula ΔP _h0 =Q ₀ ×R ₀ , where R ₀ represents the preset blocking flow resistance, Q ₀ represents the rated flow rate, and ΔP _h0 represents the rated blocking pressure difference. The flow resistance factor target value can then be calculated according to the rated blocking pressure difference and the fluid dynamic pressure.

In the embodiment of the present invention, since the preset target flow resistance refers to the flow resistance when the target loss part needs to be cleaned or replaced under the rated flow rate, the rated blocking pressure difference calculated based on the preset target flow resistance is also the pressure difference when the target loss part needs to be cleaned or replaced, that is, the flow resistance factor target value represents the flow resistance factor when the target loss part needs to be cleaned or replaced. Moreover, compared with the pressure difference empirical value used as the comparison object in the related art, the flow resistance factor target value is more objective and accurate, is not affected by flow fluctuations, and has a wider applicability.

Referring to FIG. 3 , a flowchart of implementing step 201 in the method for detecting the health of consumable parts of a liquid cooling system provided by an embodiment of the present invention is shown, as shown in FIG. 3 :

Step 2011, obtaining the rated flow of the target loss component, and determining the rated flow rate according to the rated flow;

Step 2012: obtaining a preset blocking flow resistance of a target loss component, and determining a rated blocking pressure difference according to the preset blocking flow resistance and a rated flow rate;

Step 2013, obtaining the medium density of the cooling liquid in the liquid cooling system;

Step 2014: Obtain a target value of a flow resistance factor of a target loss component according to the rated blocking pressure difference, the rated flow velocity, the medium density, and a preset first calculation formula;

Wherein, the first calculation formula includes:

Wherein, ξ ₀ represents the target value of the flow resistance factor, ΔP _h0 represents the rated blocking pressure difference, ρ represents the medium density of the cooling liquid, and _v0 represents the rated flow rate.

In an embodiment of the present invention, the rated flow rate can be determined according to the rated flow rate of the system, the pipe diameter of the target loss part and the medium density of the cold liquid, for example, based on the calculation method given in the following embodiment. After the preset blocking flow resistance is determined, the rated blocking pressure difference can be obtained according to the formula ΔP _h0 =Q ₀ ×R ₀ ; then the target value of the flow resistance factor can be calculated according to the rated blocking 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 by dividing the rated flow rate by the pipeline cross-sectional area of the target loss part, and the pipeline cross-sectional area of the target loss part can be calculated based on the pipe diameter. Finally, the preset blocking flow resistance multiplied by the rated flow rate can obtain the rated blocking pressure difference of the target loss part, and the target value of the flow resistance factor of the target loss part can be determined according to the rated flow rate and the rated blocking pressure difference.

It can be seen that in this embodiment, since the preset target flow resistance refers to the flow resistance when the target loss part needs to be cleaned or replaced at the rated flow rate, the rated blocking pressure difference calculated based on the preset target flow resistance is also the pressure difference when the target loss part needs to be cleaned or replaced, that is, the flow resistance factor target value represents the flow resistance factor when the target loss part needs to be cleaned or replaced. Compared with the pressure difference empirical value used as the comparison object in the related art, the flow resistance factor target value is more objective and accurate, is not affected by flow fluctuations, and has a wider applicability.

It should be pointed out that the above first calculation formula is only a better way to calculate the flow resistance factor. Other methods for calculating the flow resistance factor based on flow resistance or the ratio of the pressure difference on both sides and the fluid dynamic pressure are applicable to the present invention, which also has higher accuracy and wider applicability than the existing technology.

In a further embodiment, the above-mentioned obtaining the rated flow of the target loss component and determining the rated flow rate according to the rated flow may include:

Obtain the pipe diameter of the target lossy part;

Determine the rated flow rate of the target loss part according to the rated flow rate, pipe diameter and preset flow rate calculation formula;

The flow rate calculation formula includes:

Among them, _Q0 represents the rated flow rate and D represents the pipe diameter.

In the embodiment of the present invention, based on the system inherent design parameters or inherent physical parameters such as the rated flow rate and pipe diameter of the target loss component, the rated flow rate of the target loss component can be calculated using a flow rate calculation formula.

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

In the embodiment of the present invention, 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 conditions of actual flow rate and actual pressure difference.

In a specific embodiment, the above step 202 may include:

Obtain the actual pressure difference between the front and rear ends of the target loss component;

Obtaining the actual flow rate of the cooling liquid in the target loss part;

Obtain the medium density of the cooling liquid in the liquid cooling system;

Obtaining an actual value of the flow resistance factor of the target loss component according to the actual pressure difference, the actual flow velocity, the medium density and a preset second calculation formula;

Wherein, the second calculation formula includes:

Among them, ξ ₁ represents the actual value of the flow resistance factor, _v1 represents the actual flow velocity, ρ represents the medium density of the cold liquid, and ΔP _h1 represents the actual pressure difference.

In practical applications, referring to the liquid cooling system shown in Figure 1, the actual flow rate on the primary side can be measured by the flow transmitter FT11, and the actual flow rate on the secondary side can be measured by the flow transmitter FT21. The actual flow rate can be calculated based on the actual flow rate and pipe diameter.

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

In an embodiment of the present invention, the actual value of the flow resistance factor is calculated based on the actual pressure difference between the front and rear ends of the target loss part, the density of the cold liquid medium and the actual flow velocity, and can truly reflect the fluid blockage situation of the target loss part in the current working state. By comparing it with the target value of the flow resistance factor, the health status of the target loss part can be determined. For example, when blockage occurs in the target loss part, the actual value of the flow resistance factor increases. As the actual value of the flow resistance factor gradually increases, it indicates that the health of the target loss part gradually decreases. When the actual value of the flow resistance factor increases to be consistent with the target value of the flow velocity factor, it indicates that the health is 0, and the target loss part needs to be cleaned or replaced.

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 of the target loss component.

In an embodiment of the present invention, the health condition of the target loss component 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 difference between the target value of the flow resistance factor and the actual value of the flow resistance factor is not large, it can be considered that the health condition of the target loss component is not good and needs to be cleaned or replaced. When the target value of the flow resistance factor is still significantly different from the actual value of the flow resistance factor, it can be considered that the health condition of the target loss component is good.

In one embodiment, the above step 203 may specifically include: dividing the actual value of the flow resistance factor by the target value of the flow resistance factor to obtain a loss ratio; and subtracting the loss ratio from 1 to obtain the health of the target loss component.

In this embodiment, the ratio of the actual value of the flow resistance factor to the target value of the flow resistance factor is used as the loss ratio, and the health of the target loss component is obtained by subtracting the loss ratio from 1. For example, if the target value of the flow resistance factor is 100 and the actual value of the flow resistance factor is 30, then the health of the target loss component is 70% (1-30/100).

In another embodiment, the above step 203 may specifically include: obtaining multiple actual values of flow resistance factors within a preset time period, and calculating the change rate of the actual value of the flow resistance factor; determining the remaining available time of the target loss component according to the target value of the flow resistance factor and the change rate of the actual value of the flow resistance factor.

In this embodiment, the actual value of the flow resistance factor can be continuously monitored and calculated over a continuous period of time, and a curve graph showing the change of the actual value of the flow resistance factor over time can be generated based on the corresponding relationship between time and the actual value of the flow resistance factor. The curve graph can reflect the rate of change of the actual value of the flow resistance factor. According to the rate of change of the actual value of the flow resistance factor, it can be known how long it will take for the flow resistance factor to reach the target value of the flow resistance factor, thereby determining the remaining usable time of the target wear part, that is, the life prediction of the target wear part can be achieved. Exemplarily, the target value of the flow resistance factor is 100. Based on the curve determined by multiple actual values of the flow resistance factor within a preset time, it is calculated that the rate of change of the actual value of the flow resistance factor increases by 1 every 12 hours. If the current actual value of the flow resistance factor is 20, it means that the target wear part can still operate normally for 960 hours, and then needs to be cleaned and replaced. That is, the life of the target wear part is still 960 hours, or 40 days.

It should be noted that the method of judging the health of the consumable parts by the pressure difference at both ends of the consumable parts in the related art is that the pressure difference is affected by the cold liquid flow rate, and its actual value is irregular, making it difficult to predict the life of the consumable parts. Only a real-time value with poor accuracy can be obtained. The solution of the present invention performs health detection based on the flow resistance factor, which is not affected by changes in the cold liquid flow rate, and achieves more accurate judgment of the health and prediction of the life of the consumable parts.

It should be noted that for a plate heat exchanger, since it has two independent flow paths, the health of the primary side and the secondary side need to be calculated separately, and the two are independent.

As can be seen from the above, the present invention provides a method for detecting the health of consumable parts of a liquid cooling system, by obtaining the target value of the flow resistance factor and the actual value of the flow resistance factor of the target consumable part, and then comparing the target value of the flow resistance factor and the actual value of the flow resistance factor, thereby obtaining the health of the target consumable part. The present invention proposes for the first time a method for judging the health of the target consumable part 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 pipe, the bending of the pipe, the viscosity of the fluid and other factors when the fluid flows in the pipe. 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 judgment method based on the pressure difference at both ends of the consumable part in the prior art, 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, and can also accurately evaluate the blockage of the consumable part in the variable flow system, thereby improving the accuracy of the health detection of the consumable parts of the liquid cooling system.

It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
