[0002] Gas testing is widely used to verify the airtightness of workpieces. Its principle is as follows: The workpiece is inflated to a specific target test pressure, then disconnected from the air source to allow the pressure to stabilize. The stabilized pressure is P1, and the pressure measured over a specified time is P2. The pressure decay is calculated as ΔP = P1 - P2.

[0026] According to an embodiment of the present application, a method for determining an airtightness threshold is provided.

[0027] Figure 1 FIG. 1 is a flow chart of a method for determining an airtightness threshold according to an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0028] Step S101, obtaining a plurality of liquid cooling radiators with different leakage rates;

[0031] Step S104, a gas tightness threshold is determined according to at least the pressure drop value.

[0032] In the method for determining the gas tightness threshold, first, a plurality of liquid cooling radiators with different leakage amounts are obtained; then, pressure leak detection and liquid leak detection are performed on the plurality of liquid cooling radiators, and a portion of the liquid cooling radiators satisfying a predetermined condition is determined as a target liquid cooling radiator, the liquid leak detection is a detection of whether the liquid cooling radiator leaks after cooling liquid is introduced into the liquid cooling radiator, and the predetermined condition is that the number of bubbles generated in the pressure leak detection is within a predetermined range and the liquid cooling radiator does not leak; then, air leak detection is performed on all the target liquid cooling radiators, and a pressure drop value is determined, the pressure drop value is a pressure change value of the target liquid cooling radiator in the air leak detection, and the air leak detection is a detection of charging the target liquid cooling radiator with air and testing the pressure; finally, a gas tightness threshold is determined according to at least the pressure drop value. Compared with the prior art in which the gas tightness standard is determined only according to industry experience, the problem that the gas tightness standard is not objective and accurate is avoided, and the method for determining the gas tightness threshold has the following advantages. The liquid cooling radiators with different leakage amounts are subjected to pressure leak detection and liquid leak detection, and the target liquid cooling radiators in which the number of bubbles generated in the pressure leak detection is within a predetermined range and the liquid cooling radiators do not leak in the liquid leak detection are selected, so that the target liquid cooling radiators meet the requirement of leaking air but not leaking liquid. The air leak detection is performed on all the target liquid cooling radiators, the pressure drop value is obtained, and the gas tightness threshold is determined according to at least the pressure drop value, so that the target liquid cooling radiators corresponding to the gas tightness threshold meet the requirement of leaking air but not leaking liquid. The gas tightness threshold is determined according to the actual performance of the liquid cooling radiator, the accuracy of the gas tightness threshold is high, and the problem that the gas tightness standard is not objective and accurate in the prior art is avoided.

[0033] According to a specific embodiment of the present application, a plurality of the above-mentioned liquid-cooled radiators are leak-tested to determine that some of the above-mentioned liquid-cooled radiators that meet predetermined conditions are target liquid-cooled radiators, including: performing the above-mentioned pressure leak test on the plurality of the above-mentioned liquid-cooled radiators to determine that the above-mentioned liquid-cooled radiators that meet the first predetermined condition are the first reserve liquid-cooled radiators, wherein the first predetermined condition is that the number of the above-mentioned bubbles generated is within the above-mentioned predetermined range; performing the above-mentioned liquid test on the plurality of the above-mentioned first reserve liquid-cooled radiators to determine that the above-mentioned first reserve liquid-cooled radiators that meet the second predetermined condition are the above-mentioned target liquid-cooled radiators, wherein the above-mentioned second predetermined condition is that the above-mentioned liquid-cooled radiators do not leak liquid. By screening out the above-mentioned first reserve liquid-cooled radiators whose number of bubbles in the leak test process is within the above-mentioned predetermined range through the above-mentioned pressure leak test method, and then screening out the above-mentioned target liquid-cooled radiators that do not leak the above-mentioned coolant during the above-mentioned liquid test process through the above-mentioned liquid test on the above-mentioned first reserve liquid-cooled radiators, it is further ensured that the obtained target liquid-cooled radiators meet the requirements of leaking air but not leaking liquid, and further ensures that the accuracy of the above-mentioned airtightness threshold is high.

[0034] In a specific embodiment, the pressure leak detection is to fill the liquid-cooled radiator with air of a certain pressure, then immerse the liquid-cooled radiator in water, and determine whether there is a leak by observing the bubbles in the liquid-cooled radiator. The predetermined range is the presence of tiny bubbles or no obvious bubbles.

[0035] Specifically, before the liquid inspection, all the first preliminary liquid-cooled radiators are connected to form a system, and then the coolant is circulated in the system to observe whether there is leakage.

[0036] In order to further ensure that the determined air tightness threshold is more objective and more accurate, according to another specific embodiment of the present application, all the above-mentioned target liquid-cooled radiators are gas-tested to determine multiple pressure drop values, including: inflating all the above-mentioned target liquid-cooled radiators so that the pressure in the above-mentioned target liquid-cooled radiators after inflation reaches the target detection pressure, and the above-mentioned target detection pressure is the preset maximum pressure that the above-mentioned liquid-cooled radiator can withstand; obtaining the first pressure corresponding to all the above-mentioned target liquid-cooled radiators after the first predetermined time period of inflation is completed, and the second pressure corresponding to all the above-mentioned target liquid-cooled radiators after the second predetermined time period of inflation is completed, and the above-mentioned second predetermined time period is greater than the above-mentioned first predetermined time period; calculating the difference between the above-mentioned first pressure and the corresponding above-mentioned second pressure to obtain the above-mentioned pressure drop value. By inflating the target liquid-cooled radiator to the maximum pressure that the liquid-cooled radiator can withstand, and then obtaining the first pressure after the first predetermined time after stopping inflation and the second pressure after the second predetermined time, the first pressure is subtracted from the second pressure to obtain the pressure drop value, thereby ensuring that the pressure drop value can be obtained relatively simply and accurately, and further ensuring that the air tightness threshold subsequently determined based on the pressure drop value has high accuracy.

[0037] In a specific embodiment, the target detection pressure can be obtained from the instruction manual of the liquid-cooled radiator.

[0038] According to another specific embodiment of the present application, before obtaining the first pressure corresponding to all the above-mentioned target liquid-cooled radiators after the first predetermined time period after the inflation ends, and the second pressure corresponding to all the above-mentioned target liquid-cooled radiators after the second predetermined time period after the inflation ends, after inflating all the above-mentioned target liquid-cooled radiators, the above-mentioned method further includes: obtaining the volume of all the above-mentioned liquid-cooled radiators; and determining the above-mentioned first predetermined time period and the above-mentioned second predetermined time period corresponding to the above-mentioned liquid-cooled radiators based on the above-mentioned volumes. Determining the above-mentioned first predetermined time period and the above-mentioned second predetermined time period based on the volume of the above-mentioned liquid-cooled radiators ensures that the above-mentioned first predetermined time period and the above-mentioned second predetermined time period are determined based on the actual performance of the above-mentioned liquid-cooled radiators, thereby ensuring that the determined above-mentioned pressure drop value is consistent with the actual performance of the above-mentioned liquid-cooled radiators, further ensuring the objectivity and high accuracy of the above-mentioned airtightness threshold, and further avoiding the problem in the prior art that the airtightness standard is determined only based on industry experience, resulting in the airtightness standard being not objective and accurate enough.

[0039] In a specific embodiment, the smaller the volume of the liquid-cooled radiator, the shorter the first and second predetermined time periods. These time periods can generally be determined based on existing project experience. Specifically, if the volume of the liquid-cooled radiator is 60 ml, the first predetermined time period after the inflation stops is 15 seconds, and the second predetermined time period is 25 seconds.

[0040] According to a specific embodiment of the present application, there are multiple pressure drop values ​​mentioned above, and the air tightness threshold is determined at least based on the above pressure drop values, including: obtaining the standard pressure drop value in the international standard of the above liquid-cooled radiator; calculating the product of the maximum value of each of the above pressure drop values ​​and the predetermined coefficient t to obtain a preliminary pressure drop value, and the above predetermined coefficient satisfies 0<t≤1; determining whether the above preliminary pressure drop value is greater than the above standard pressure drop value; when the above preliminary pressure drop value is not greater than the above standard pressure drop value, determining the above preliminary pressure drop value as the above air tightness threshold. The above-mentioned preliminary pressure drop value is obtained by multiplying the above-mentioned maximum value among the above-mentioned pressure drop values ​​by the above-mentioned predetermined coefficient, so that the above-mentioned preliminary pressure drop value is not greater than the maximum value among the above-mentioned pressure drop values, and then the above-mentioned preliminary pressure drop value is compared with the above-mentioned standard pressure drop value in the above-mentioned international standard. In the case that the above-mentioned preliminary pressure drop value is not greater than the above-mentioned standard pressure drop value, the above-mentioned preliminary pressure drop value is determined to be the above-mentioned air-tightness threshold value, which further ensures that the above-mentioned air-tightness threshold value obtained by the above-mentioned preliminary pressure drop value is not greater than the above-mentioned standard pressure drop value in the above-mentioned international standard. In this way, the above-mentioned air-tightness threshold value obtained can be more stringent, thereby ensuring that the liquid-cooled radiator that is subsequently judged to be qualified according to the air-tightness threshold value has basically no air-tightness problems.

[0041] In a specific embodiment, as shown in Table 1, the pressure drop value corresponding to the liquid-cooled radiator with code 14 is 213.8 Pa, which is the critical value for air leakage without liquid leakage. That is, if the pressure drop value of the liquid-cooled radiator is less than 213.8 Pa, the liquid-cooled radiator can be guaranteed to leak air but not liquid. However, if the pressure drop value of the liquid-cooled radiator is greater than 213.8 Pa, liquid leakage may occur. Specifically, the predetermined coefficient t can be set to 0.5, that is, the standard is established according to the above-mentioned preliminary pressure drop value ≤ 106.9 Pa. The established standard can ensure that the coolant does not leak.

[0042] Table 1

[0043]

[0044] Specifically, since the magnitude of the above pressure drop value is related to the leakage time, through the formula PV = nRT, the relationship between the above preliminary pressure drop value and the leakage amount can be obtained as follows: If, where V is the volume of the above-mentioned liquid-cooled radiator being tested, 60 ml, ΔP is the above-mentioned preliminary pressure drop value, 100 Pa, Pa is the atmospheric pressure, 101325 Pa, and T is the test time, 10 seconds, it can be seen that the above-mentioned leakage volume Q is 0.35 ml / min. In the international standard, the leakage volume is required to be ≤2.5 ml / min. Therefore, the above-mentioned air tightness threshold obtained in this application is lower than the above-mentioned international standard.

[0045] In a specific embodiment, when the above-mentioned preliminary pressure drop value is greater than the above-mentioned standard pressure drop value, the above-mentioned preliminary pressure drop value is re-determined by modifying the above-mentioned predetermined coefficient t until the above-mentioned preliminary pressure drop value is no greater than the above-mentioned standard pressure drop value.

[0046] According to another specific embodiment of the present application, obtaining multiple liquid-cooled radiators with different leakage amounts includes: using laser marking technology to obtain the liquid-cooled radiators with different leakage amounts. Obtaining the liquid-cooled radiators with different leakage amounts using laser marking technology ensures that multiple pressure drop values ​​can be obtained during testing, ensuring that the airtightness threshold value ultimately determined after the leak detection of the liquid-cooled radiator is highly accurate.

[0047] Specifically, the laser marking is to locally irradiate the liquid-cooled radiator with a high-energy-density laser, causing the surface material to vaporize or undergo a chemical reaction that causes a color change, thereby obtaining the liquid-cooled radiator with different leakage amounts.

[0048] The present application also provides an apparatus for determining an airtightness threshold. It should be noted that the apparatus for determining an airtightness threshold in the present application can be used to execute the method for determining an airtightness threshold provided in the present application.

[0051] According to a specific embodiment of the present application, the first determination unit includes a first determination module and a second determination module, wherein the first determination module is used to perform the pressure leak detection on the plurality of the liquid-cooled radiators, and determine that the liquid-cooled radiator that meets the first predetermined condition is the first reserve liquid-cooled radiator, and the first predetermined condition is that the number of bubbles generated is within the predetermined range; the second determination module is used to perform the liquid detection on the plurality of the first reserve liquid-cooled radiators, and determine that the first reserve liquid-cooled radiator that meets the second predetermined condition is the target liquid-cooled radiator, and the second predetermined condition is that the liquid-cooled radiator does not leak liquid. The pressure leak detection method is used to screen out the first reserve liquid-cooled radiators whose number of bubbles in the leak detection process is within the predetermined range, and then the liquid detection is performed on the first reserve liquid-cooled radiators to screen out the target liquid-cooled radiators that do not leak the coolant during the liquid detection process, further ensuring that the target liquid-cooled radiator meets the requirements of leaking air but not leaking liquid, and further ensuring that the accuracy of the airtightness threshold is high.

[0052] In a specific embodiment, the pressure leak detection is to fill the liquid-cooled radiator with air of a certain pressure, then immerse the liquid-cooled radiator in water, and determine whether there is a leak by observing the bubbles in the liquid-cooled radiator. The predetermined range is the presence of tiny bubbles or no obvious bubbles.

[0053] Specifically, before the liquid inspection, all the first preliminary liquid-cooled radiators are connected to form a system, and then the coolant is circulated in the system to observe whether there is leakage.

By inflating the target liquid-cooled radiator to the maximum pressure that the liquid-cooled radiator can withstand, and then obtaining the first pressure after the first predetermined time after stopping inflation and the second pressure after the second predetermined time, the first pressure is subtracted from the second pressure to obtain the pressure drop value, thereby ensuring that the pressure drop value can be obtained relatively simply and accurately, and further ensuring that the air tightness threshold subsequently determined based on the pressure drop value has high accuracy.

[0057] In a specific embodiment, the smaller the volume of the liquid-cooled radiator, the shorter the first and second predetermined time periods. These time periods can generally be determined based on existing project experience. Specifically, if the volume of the liquid-cooled radiator is 60 ml, the first predetermined time period after the inflation stops is 15 seconds, and the second predetermined time period is 25 seconds.

[0058] According to a specific embodiment of the present application, there are multiple pressure drop values, and the third determination unit includes a second acquisition module, a second calculation module, a third determination module and a fourth determination module, wherein the second acquisition module is used to obtain the standard pressure drop value in the international standard of the liquid-cooled radiator; the second calculation module is used to calculate the product of the maximum value of each of the above pressure drop values ​​and the predetermined coefficient t to obtain a preliminary pressure drop value, and the above predetermined coefficient satisfies 0<t≤1; the third determination module is used to determine whether the preliminary pressure drop value is greater than the standard pressure drop value; the fourth determination module is used to determine that the preliminary pressure drop value is the air tightness threshold when the preliminary pressure drop value is not greater than the standard pressure drop value. The above-mentioned preliminary pressure drop value is obtained by multiplying the above-mentioned maximum value among the above-mentioned pressure drop values ​​by the above-mentioned predetermined coefficient, so that the above-mentioned preliminary pressure drop value is not greater than the maximum value among the above-mentioned pressure drop values, and then the above-mentioned preliminary pressure drop value is compared with the above-mentioned standard pressure drop value in the above-mentioned international standard. In the case that the above-mentioned preliminary pressure drop value is not greater than the above-mentioned standard pressure drop value, the above-mentioned preliminary pressure drop value is determined to be the above-mentioned air-tightness threshold value, which further ensures that the above-mentioned air-tightness threshold value obtained by the above-mentioned preliminary pressure drop value is not greater than the above-mentioned standard pressure drop value in the above-mentioned international standard. In this way, the above-mentioned air-tightness threshold value obtained can be more stringent, thereby ensuring that the liquid-cooled radiator that is subsequently judged to be qualified according to the air-tightness threshold value has basically no air-tightness problems.

[0059] In a specific embodiment, as shown in Table 1, the pressure drop value corresponding to the liquid-cooled radiator with code 14 is 213.8 Pa, which is the critical value for air leakage without liquid leakage. That is, if the pressure drop value of the liquid-cooled radiator is less than 213.8 Pa, the liquid-cooled radiator can be guaranteed to leak air but not liquid. However, if the pressure drop value of the liquid-cooled radiator is greater than 213.8 Pa, liquid leakage may occur. Specifically, the predetermined coefficient t can be set to 0.5, that is, the standard is established according to the above-mentioned preliminary pressure drop value ≤ 106.9 Pa. The established standard can ensure that the coolant does not leak.

[0060] Specifically, since the magnitude of the above pressure drop value is related to the leakage time, through the formula PV = nRT, the relationship between the above preliminary pressure drop value and the leakage amount can be obtained as follows: If, wherein V is the volume 60ml of the liquid cooling radiator to be measured, ΔP is the above-mentioned preliminary pressure drop value 100Pa, Pa is the atmospheric pressure 101325Pa, and T is the test time 10S, it can be known that the leakage Q is 0.35ml / min, and in the international standard, the leakage requirement is ≤2.5ml / min, so that the above-mentioned air tightness threshold value obtained by the application is less than the above-mentioned international standard.

[0061] In a specific embodiment, in the case that the above-mentioned preliminary pressure drop value is greater than the above-mentioned standard pressure drop value, the above-mentioned preliminary pressure drop value is re-determined by modifying the above-mentioned predetermined coefficient t until the above-mentioned preliminary pressure drop value is not greater than the above-mentioned standard pressure drop value.

[0062] According to another specific embodiment of the application, the above-mentioned first obtaining unit comprises a third obtaining module, and the third obtaining module is configured to obtain the liquid cooling radiator with different leakage by using a laser marking technology. By using the laser marking technology to obtain the liquid cooling radiator with different leakage, it is ensured that multiple pressure drop values can be obtained, and it is ensured that the air tightness threshold value of the liquid cooling radiator determined through the leak detection is relatively high in accuracy.

[0063] Specifically, the laser marking is to locally irradiate the liquid cooling radiator by using a high-energy-density laser, so that the surface layer material is vaporized or a chemical reaction of color change occurs, thereby obtaining the liquid cooling radiator with different leakage.

[0064] The air tightness threshold value determination device comprises a processor and a memory, and the first obtaining unit, the first determining unit, the second determining unit and the third determining unit are stored in the memory as program units, and the corresponding functions are realized by the processor executing the program units stored in the memory.
