Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a liquid cooling system according to an embodiment of the present invention. As shown in fig. 1, the liquid cooling system includes a primary side and a secondary side, the primary side and the secondary side exchange heat through the plate heat exchanger HE01, the primary side and the secondary side cool liquid flow in the direction of black arrow in fig. 1, the primary side is provided with a flow transducer FT11, pressure transducers PT11 and PT12, FT11 can be used to measure cool liquid flow of the primary side, PT11 and PT12 can be used to measure differential pressure of two ends of the primary side of the plate heat exchanger HE01 (related art performs blocking judgment of the primary side of the plate heat exchanger based on comparison of the differential pressure and differential pressure empirical value). The secondary side is provided with a flow transducer FT21, a filter FL211, and pressure transducers PT21, PT22 and PT23; FT21 may be used to measure the flow rate of cold liquid on the secondary side, and PT22 and PT23 may be used to measure the differential pressure across the secondary side of the plate heat exchanger HE01 (the related art performs the clogging judgment of the secondary side of the plate heat exchanger based on the comparison of the differential pressure and the differential pressure empirical value), and PT21 and PT22 are used to measure the differential pressure across the filter FL211 (the related art performs the clogging judgment of the both sides of the filter based on the comparison of the differential pressure and the differential pressure empirical value).
The plate heat exchanger HE01 and the filter FL211 shown in FIG. 1 are easy to be blocked after being used for a period of time, and the heat dissipation or heat exchange effect is affected, which is called a loss element in the invention.
Referring to fig. 2, a flowchart of an implementation of a method for detecting the health of a lossy member of a liquid cooling system according to an embodiment of the present invention is shown, and details are as follows:
in step 201, a target value of the flow resistance factor of the target lossy member is obtained.
In the embodiment of the invention, the target loss element can be a filter in the liquid cooling system or a heat exchanger in the liquid cooling system, namely a device which can be blocked in the liquid cooling system to influence the heat dissipation or heat exchange effect.
In embodiments of the present invention, the flow resistance factor is generally used to describe the resistance caused by friction of the inner wall of a pipe, pipe bending, fluid viscosity, and other factors when a fluid flows in the pipe, and is a dimensionless number that can be expressed as a ratio of resistance to fluid dynamic pressure.
In an embodiment of the invention, the target flow resistance factor value is indicative of the flow resistance factor of the target flow loss member at the rated flow rate and the preset blocking flow resistance condition. The rated flow is the flow of cold liquid (fluid) passing through the target loss member in a standard working state preset by the liquid cooling system, the preset blocking flow resistance refers to the flow resistance when the target loss member is blocked in the preset rated flow and needs cleaning or replacement, the value can be obtained by carrying out a real blocking experiment or a simulated blocking experiment on the target loss member, and the preset blocking flow resistance depends on the pipe diameter, the pipe length and the viscosity coefficient of the fluid of the target loss member. For example, the value of the preset obstruction flow resistance may be determined according to the pipe diameter in the obstruction state, for example, the obstruction pipe diameter is considered to be one half of the normal pipe diameter.
After determining the preset occlusion flow resistance, the nominal occlusion pressure difference may be obtained according to the formula Δp h0＝Q0×R0, where R 0 represents the preset occlusion flow resistance, Q 0 represents the nominal flow, and Δp h0 represents the nominal occlusion pressure difference. And then the target value of the flow resistance factor can be calculated according to the rated blocking pressure difference and the fluid dynamic pressure.
In the embodiment of the invention, since the preset target flow resistance refers to the flow resistance when the target wearing part needs cleaning or replacement 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 wearing part needs cleaning or replacement, that is, the flow resistance factor target value indicates the flow resistance factor when the target wearing part needs cleaning or replacement. Compared with the differential pressure empirical value as the comparison object in the related art, the flow resistance factor target value is more objective and accurate, is not influenced by flow fluctuation, and has wider applicability.
Referring to fig. 3, a flowchart of one implementation of step 201 in the method for detecting the health of a lossy member of a liquid cooling system according to the embodiment of the present invention is shown in fig. 3:
2011, acquiring rated flow of a target loss element, and determining rated flow rate according to the rated flow;
Step 2012, acquiring preset blocking flow resistance of the target loss element, and determining rated blocking pressure difference according to the preset blocking flow resistance and the rated flow;
2013, obtaining medium density of cold liquid in the liquid cooling system;
2014, obtaining a flow resistance factor target value of a target loss element according to the rated blocking pressure difference, the rated flow rate, the medium density and a preset first calculation formula;
Wherein the first calculation formula includes:
Where ζ 0 represents a flow resistance factor target value, Δp h0 represents a rated blocking pressure difference, ρ represents a medium density of the cold liquid, and v0 represents a rated flow rate.
In the embodiment of the invention, the rated flow rate can be determined according to the rated flow rate of the system, the pipe diameter of the target loss element and the medium density of the cold liquid, and is obtained based on the calculation mode given in the following embodiment. After the preset occlusion flow resistance is determined, the nominal occlusion pressure difference can be obtained according to the formula ΔP h0＝Q0×R0; and 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 and the rated flow rate of the cold liquid, the rated flow rate can be obtained by dividing the rated flow rate by the pipeline sectional area of the target loss member, and the pipeline sectional area of the target loss member can be calculated based on the pipe diameter. And finally, multiplying the preset blocking flow resistance by the rated flow to obtain the rated blocking pressure difference of the target loss element, and determining the flow resistance factor target value of the target loss element according to the rated flow rate and the rated blocking pressure difference.
It can be seen that, in the present embodiment, since the preset target flow resistance refers to the flow resistance when the target wearing part needs cleaning or replacement 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 wearing part needs cleaning or replacement, that is, the flow resistance factor target value indicates the flow resistance factor when the target wearing part needs cleaning or replacement. Compared with the differential pressure experience value as a comparison object in the related art, the flow resistance factor target value is more objective and accurate, is not influenced by flow fluctuation, and has wider applicability.
It should be noted that the above first calculation formula is only a preferred calculation mode of the flow resistance factor, and other methods for calculating the flow resistance factor based on the flow resistance or the ratio of the differential pressure between two sides and the hydrodynamic pressure are suitable for the present invention, and have higher accuracy and wider applicability compared with the prior art.
In a further embodiment, the obtaining the rated flow rate of the target loss element and determining the rated flow rate according to the rated flow rate may include:
acquiring the pipe diameter of a target loss piece;
Determining the rated flow rate of the target loss element according to the rated flow rate, the pipe diameter and a preset flow rate calculation formula;
Wherein, the flow rate calculation formula includes:
Wherein Q 0 represents rated flow and D represents pipe diameter.
In the embodiment of the invention, the rated flow rate of the target loss element can be calculated by a flow rate calculation formula based on the inherent design parameters or inherent physical parameters of the system such as the rated flow rate and the pipe diameter of the target loss element.
In step 202, an actual value of the flow resistance factor of the target lossy member is obtained.
In an embodiment of the present invention, the actual value of the flow resistance factor of the target loss element represents the flow resistance factor of the target loss element under actual flow and actual differential pressure conditions.
In a specific embodiment, the step 202 may include:
Acquiring the actual pressure difference of the front end and the rear end of the target loss element;
Acquiring the actual flow rate of the cold liquid in the target loss member;
acquiring medium density of cold liquid in a liquid cooling system;
obtaining an actual flow resistance factor value of the target loss element 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:
Where ζ 1 represents the actual flow resistance factor, v1 represents the actual flow rate, 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 fig. 1, the actual flow rate of the primary side can be measured according to the flow transducer FT11, the actual flow rate of the secondary side can be measured according to the flow transducer FT21, and the actual flow rate can be calculated according to the actual flow rate and the pipe diameter.
The actual differential pressure of filter FL211 can be derived from the difference between the measurements of pressure transmitters PT21 and PT 22; the actual pressure difference on the primary side of the plate heat exchanger HE01 can be obtained from the difference between the measured values of the pressure transmitters PT11 and PT 12; the actual pressure difference on the secondary side of the plate heat exchanger HE01 can be obtained from the difference between the measured values of the pressure transmitters PT22 and PT 23. Thus, the actual flow resistance factors of the filter FL211, the primary side and the secondary side of the plate heat exchanger HE01 can be calculated.
In the embodiment of the invention, the actual flow resistance factor value is calculated based on the actual pressure difference, the cold liquid medium density and the actual flow velocity at the front end and the rear end of the target loss member, the fluid blocking condition of the target loss member in the current working state can be truly reflected, the current working state of the target loss member can be determined by comparing the actual flow resistance factor value with the target flow resistance factor value, for example, when the target loss member is blocked, the actual flow resistance factor value becomes larger, the health degree of the target loss member is gradually reduced along with the gradual increase of the actual flow resistance factor value, the health degree is 0 when the actual flow resistance factor value is increased to be consistent with the target flow rate factor value, and the target loss member needs cleaning or replacement.
In step 203, the target flow resistance factor value and the actual flow resistance factor value are compared to obtain the health of the target wearing part.
In the embodiment of the invention, the health condition of the target loss element can be obtained by comparing the flow resistance factor target value with the flow resistance factor actual value, for example, when the flow resistance factor target value and the flow resistance factor actual value are not great, the health condition of the target loss element can be considered to be bad, cleaning or replacement is required, and when the flow resistance factor target value is still great from the flow resistance factor actual value, the health condition of the target loss element can be considered to be good.
In one embodiment, the step 203 may specifically include: dividing the actual flow resistance factor value by the target flow resistance factor value to obtain a loss proportion; subtracting the loss ratio from 1 to obtain the health of the target loss.
In this embodiment, the ratio of the actual flow resistance factor value to the target flow resistance factor value is taken as the loss ratio, and the loss ratio is subtracted from 1 to obtain the health of the target loss element, for example, the target flow resistance factor value is 100, the actual flow resistance factor value is 30, and the health of the target loss element is 70% (1-30/100).
In another embodiment, the step 203 may specifically include: acquiring a plurality of actual flow resistance factor values in a preset time period, and calculating the change rate of the actual flow resistance factor values; and determining the residual available duration of the target loss element according to the change rates of the flow resistance factor target value and the flow resistance factor actual value.
In this embodiment, the continuous actual value of the flow resistance factor may be continuously monitored and calculated for a period of time, and a graph of the change of the actual value of the flow resistance factor with time may be generated according to the correspondence between time and the actual value of the flow resistance factor, where the graph may represent the rate of change of the actual value of the flow resistance factor, and how long the flow resistance factor will reach the target value of the flow resistance factor may be known according to the rate of change of the actual value of the flow resistance factor, so that the remaining available time of the target loss element is determined, and thus, life prediction for the target loss element may be implemented. By way of example, a target value of 100 for the flow resistance factor, based on a curve determined by a plurality of actual values of the flow resistance factor over a preset period of time, the rate of change of the actual value of the flow resistance factor calculated to be increased by 1 every 12 hours, if the current actual value of the flow resistance factor is 20, means that the target wearing part can still be operated normally for 960 hours, after which cleaning and replacement are required, i.e. the life of the target wearing part is 960 hours, i.e. 40 days,
It should be noted that, in the related art, the method for judging the health degree by adopting the differential pressure at two ends of the loss element is adopted, because the differential pressure is influenced by the flow rate of the cold liquid, the actual value is irregular, the prediction of the service life of the loss element is difficult to realize, only one real-time value with poor accuracy can be obtained, and the method carries out the health degree detection based on the flow resistance factor and is not influenced by the flow rate change of the cold liquid, thereby realizing more accurate judgment of the health degree and prediction of the service life of the loss element.
It should be noted that, in the case of the plate heat exchanger, since it has two independent flow channels, it is necessary to calculate the health degree of the primary side and the secondary side separately, which are independent.
From the above, the invention provides a method for detecting the health of a liquid cooling system loss element, which is to obtain the health of the target loss element by obtaining the target flow resistance factor value and the actual flow resistance factor value of the target loss element and then comparing the target flow resistance factor value with the actual flow resistance factor value. The invention provides a method for judging health degree by utilizing a flow resistance factor for the first time, wherein the flow resistance factor is generally used for describing resistance caused by friction of the inner wall of a pipeline, bending of the pipeline, viscosity of the fluid and other factors when the fluid flows in the pipeline, and is a dimensionless number which can be expressed as the ratio of the resistance to the dynamic pressure of the fluid. Compared with the judging method based on the differential pressure at two ends of the loss piece in the prior art, the judging method based on the differential pressure at two ends of the loss piece can more accurately reflect the blocking condition of cold liquid passing through the loss piece, and can accurately evaluate the blocking condition of the loss piece under a variable flow system, so that the accuracy of detecting the health of the loss piece of the liquid cooling system is improved.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.

The invention provides a method for judging health degree by utilizing a flow resistance factor for the first time, wherein the flow resistance factor is generally used for describing resistance caused by friction of the inner wall of a pipeline, bending of the pipeline, viscosity of the fluid and other factors when the fluid flows in the pipeline, and is a dimensionless number which can be expressed as the ratio of the resistance to the dynamic pressure of the fluid. Compared with the judging method based on the differential pressure at two ends of the loss piece in the prior art, the judging method based on the differential pressure at two ends of the loss piece can more accurately reflect the blocking condition of cold liquid passing through the loss piece, and can accurately evaluate the blocking condition of the loss piece under a variable flow system, so that the accuracy of detecting the health of the loss piece of the liquid cooling system is improved.
