Description

Technical Field

[0001] The invention relates to the technical field of material research and product quality detection, in particular to a temperature and humidity balanced high-pressure accelerated aging test box. Background Art

[0002] In the fields of material research and product quality testing, high-pressure accelerated aging test chambers with balanced temperature and humidity are widely used to simulate the aging process of materials in complex environments to evaluate the performance and reliability of materials.

[0003] Currently, existing technologies typically use fixed-parameter temperature and humidity control methods, which are unable to make real-time adjustments based on temperature and humidity differences and pressure changes at different locations within the test chamber. Consequently, when pressure changes during actual testing, the temperature and humidity fluctuations cannot be compensated for in a timely manner, leading to uneven temperature and humidity within the chamber and affecting test accuracy.

[0004] Existing technologies often ignore the impact of pressure changes on temperature and humidity balance. In a high-pressure environment, changes in pressure will cause changes in temperature and humidity, but existing test chambers cannot dynamically adjust the control parameters of temperature and humidity according to real-time changes in pressure, thereby affecting the reliability of test results.

[0005] In addition, existing test chambers require manual and repeated parameter adjustments for different materials and test requirements, which is not only inefficient but also difficult to find the optimal control parameters, resulting in poor adaptability and control performance of the test chamber.

[0024] During the test, similar materials are placed in the test box, multiple tests are conducted, and after recording the test data, the compensation correlation coefficient information is calculated using the least squares method;

[0025] The specific test conditions for the compensation correlation coefficient information are as follows:

[0026] The test conditions of the humidity and pressure compensation coefficient are as follows: keeping the test temperature constant, changing the test pressure in the test chamber, and recording the corresponding stable humidity values ​​under different pressures;

[0027] The test conditions of the temperature and pressure compensation coefficient are as follows: keeping the test humidity constant, changing the test pressure, and recording the different pressure values ​​and corresponding stable temperature values ​​obtained under the changed test pressure;

When the pressure increases, it can promptly increase the amount of moisture to compensate for the resulting humidity drop, ensuring uniform and rapid humidity balance in the chamber.

[0041] Secondly, when the pressure and humidity change, the temperature change trend can be predicted in advance and adjusted, which effectively reduces temperature fluctuations and enables the environment inside the box to reach and maintain a stable equilibrium state more quickly. Among them, when calculating the adjusted humidity value and the adjusted temperature value, pressure, temperature, and humidity are considered as interrelated variables, and a correlation control mechanism between pressure and temperature and humidity is established. In this way, while adjusting the pressure, the adjustment strategy is optimized in real time according to the changes in temperature and humidity, ensuring that the temperature and humidity are always in a precise balance under high-pressure conditions.

[0042] In addition, the compensation correlation coefficient information is obtained through a large number of experiments and data statistical analysis, which can automatically adapt to different test conditions and changes in sample characteristics, and realize self-tuning of control parameters.

[0043] Second, the present invention calculates a more accurate comprehensive temperature difference by comprehensively considering the difference between the adjusted temperature value after pressure compensation and the starting temperature value and the ending temperature value, thereby accurately calculating the thermal conductivity of the material to fully reflect the temperature change during the heat conduction process.

[0066] See also Figure 1 and Figure 2 , the compensation correlation coefficient information includes humidity pressure compensation coefficient, temperature pressure compensation coefficient and temperature humidity correlation coefficient;

[0067] During the test, similar materials are placed in the test box 1, and multiple tests are conducted and the test data are recorded. Then, the least square method is used to calculate the compensation correlation coefficient information;

[0068] The specific test conditions for compensation correlation coefficient information are as follows:

[0075] ;

[0076] b is the temperature and pressure compensation coefficient, m is the number of times the temperature and pressure compensation coefficient test is recorded, u j is the difference between the different pressure values ​​obtained under the change and the initial pressure value, that is, P j -P00 obtained, where P j is the jth change in pressure value, u - is u in m trials j The average value, v j is the difference between the test temperature and the corresponding stable temperature under different pressures, that is, WD j-WD00 obtained difference, WD j is the jth temperature change value, WD00 is the temperature value before the change test, v - v is the number of trials within m j The average value of

[0077] It should be noted that, although the pressure value P is changed for the i-th time i and the jth change in pressure value P j The tests are not part of the same test, but the initial pressure value P00 before the change test in the initial setting is the same.

[0078] ;

[0079] c is the temperature-humidity correlation coefficient, p is the number of times the temperature-humidity correlation coefficient test is performed, s k The difference between the different test humidity values ​​obtained under the change and the initial humidity value, that is, SD k -SD00 obtained difference, SD k is the kth change in humidity value, s - is the number of trials within p k The average value of t k is the difference between different temperature values ​​and stable temperature value, that is, WD k -WD00 obtained difference, WD k is the kth temperature change, t - t is the number of trials within p k The average value of

[0080] It should be noted that although the humidity value SD is changed for the i-th time i and the jth change in temperature value WD j and the kth change in humidity value SD k and the kth temperature change WD k The tests are not included in the same test, but the pre-test humidity value SD00 and the pre-test temperature value WD00 before the change test in the initial setting are the same.

[0081] In this embodiment, the temperature and humidity adjustment calculation unit subtracts the initial pressure value from the pressure change value to obtain the pressure change difference;

[0082] The pressure change difference is multiplied by the humidity pressure compensation coefficient to obtain the humidity adjustment amount required to adjust the humidity value due to the pressure change;

[0083] The humidity adjustment amount is added to the humidity value to obtain the adjusted humidity value after pressure compensation;

[0085] Subtract the humidity value from the adjusted humidity value to obtain the change in the adjusted humidity. Multiply the change by the temperature-humidity correlation coefficient to obtain the second adjustment amount required to adjust the temperature value due to the humidity change. Add the first and second adjustment amounts to the temperature value to obtain the adjusted temperature value after pressure compensation.

[0090] SD0 is the basic humidity value set before the test begins, and represents the humidity condition of test chamber 1 at the initial state;

[0091] The humidity pressure compensation coefficient a is calculated through a large number of early tests.

It reflects the humidity compensation amount corresponding to the unit pressure change.

After adding the two adjustments due to pressure and humidity changes to the temperature value, the adjusted temperature value after pressure compensation is obtained.

[0094] The calculation formula for the adjusted temperature value is as follows:

[0095] ;

[0096] in:

[0097] WD is the adjusted temperature value, and WD0 is the temperature reference set at the beginning of the test.

While keeping the test humidity constant, changing the test pressure, recording the different pressure values ​​obtained under the changes and the corresponding stable temperature values, it is calculated through linear regression. It reflects the temperature compensation amount corresponding to the unit pressure change.

[0099] The temperature-humidity correlation coefficient c is obtained by linear regression by changing the test humidity value while keeping the test pressure constant and recording the different humidity values ​​and the corresponding stable temperature values. It represents the temperature change corresponding to the unit humidity change.

[0100] In this embodiment, the thermal conductivity calculation unit obtains the total heat characteristics transferred by the material under the thickness based on the heat and thickness;

[0101] According to the heat transfer area and the comprehensive temperature difference, the comprehensive ability characteristics of the material to transfer heat through the heat transfer area are obtained;

[0102] Divide the total heat characteristic by the comprehensive capacity characteristic to obtain the thermal conductivity of the material;

[0103] The calculation formula for thermal conductivity is as follows:

[0104] ;

[0106] R is the thermal conductivity, W is the amount of heat passing through the material per unit time, and W reflects the material's ability to transfer heat during the test. H is the material thickness measured directly using a gauge, and M is the heat transfer area calculated geometrically based on the shape and size of the material.

[0107] See also Figure 1 and Figure 2 , subtract the starting temperature value from the adjusted temperature value to obtain the starting temperature difference, obtain the ending temperature difference based on the ending temperature value and the adjusted temperature value, and average the starting temperature difference and the ending temperature difference to obtain the comprehensive temperature difference. The specific calculation formula is as follows:

[0108] ;

[0109] in:

[0110] △WD is the comprehensive temperature difference between the temperature adjustment value after pressure compensation and the starting temperature of the material. s is the starting temperature value detected at the beginning of the test, WD e The end temperature value detected at the end of the test;

[0111] Indicates the difference between the adjusted temperature value after pressure compensation and the starting temperature value of the material.

[0112] It represents the difference between the adjusted temperature value after pressure compensation and the final temperature value of the material. The two differences are added together to obtain a comprehensive temperature difference. Finally, the comprehensive temperature difference is averaged to obtain the comprehensive temperature difference.

[0113] The purpose of this calculation is to more comprehensively and accurately reflect the temperature changes experienced by the material during the heat conduction process, and it can better reflect the temperature influence in the actual heat conduction process than simply subtracting two temperature differences.

[0114] For example 2, please refer to Figure 2 During the test, the visualization module records the pressure change value, adjusted humidity value, adjusted temperature value and thermal conductivity corresponding to each pressure stage, and plots the data points of each pressure stage on the coordinate graph with the pressure change value as the horizontal coordinate and the thermal conductivity as the vertical coordinate. Then, these data points are connected in sequence with line segments to form a line graph of thermal conductivity changing with pressure. At the same time, as needed, lines of different colors and styles are added to distinguish the changes in thermal conductivity under different humidity and temperature conditions, and by observing the line graph, the trend of thermal conductivity changing with pressure, temperature and humidity is observed.

[0115] In this embodiment, the line graph displays the trend of thermal conductivity changing with pressure, temperature and humidity in an intuitive graphical manner. Therefore, there is no need to analyze a large amount of data. Just by observing the trend of the line graph, it is possible to quickly determine whether the thermal conductivity increases, decreases, or fluctuates with increasing pressure. This helps to grasp the overall change pattern of thermal conductivity under different environmental conditions. The line graph can also clearly identify special nodes of thermal conductivity change. These special nodes correspond to the physical and chemical changes of the material. Timely discovery of these special nodes helps to conduct in-depth research on the performance changes of the material under specific conditions.
