Description

Technical Field

[0001] This invention belongs to the field of performance testing technology for cooling materials, specifically relating to an indoor testing device and method for the performance of cooling materials. Background Technology

[0002] The application of cooling materials is becoming increasingly widespread in fields such as power equipment, electronic devices, and building envelopes. Their heat dissipation performance directly affects the operational stability, energy efficiency, and structural durability of the equipment. Taking power equipment as an example, hot and cold air convection under high summer temperatures and low winter temperatures significantly impacts the temperature distribution and heat dissipation efficiency of the equipment. Under high summer temperatures, a significant temperature difference arises between the sun-facing and shaded sides of the equipment casing, triggering asymmetric thermal expansion, which may lead to casing deformation or even cracking, threatening the equipment's insulation performance and operational safety. Under low winter temperatures, cold air convection may cause uneven temperature distribution inside the equipment, affecting its normal operation. Therefore, the research and development and performance testing of cooling materials are crucial.

[0003] Currently, the testing of the heat homogenization performance of cooling materials mainly relies on outdoor simulation experiments, but this method suffers from problems such as long testing cycles, significant weather-related influences, and poor repeatability. Laboratory testing, on the other hand, is limited to single-index evaluation and cannot comprehensively reflect the overall heat homogenization performance of the materials. In particular, existing testing methods often ignore the impact of hot and cold air convection under high summer and low winter conditions on the performance of cooling materials, leading to significant discrepancies between test results and actual application scenarios.

Obviously, the following embodiments are only some embodiments of this invention, not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] Example 1 This invention provides an indoor testing device for the performance of cooling materials, such as... Figure 1 As shown, it includes: an outer shell 13, at least four cavities 20, a dynamic hot and cold flow field simulation module, an internal heat source 11 system, an environmental control module, and an intelligent temperature monitoring module; each cavity 20 is located at the bottom inside the outer shell 13, and the outer surface of each cavity 20 is provided with the cooling material to be tested; The dynamic hot and cold flow field simulation module is located inside the outer shell 13 and is used to simulate outdoor lighting and air flow. The internal heat source 11 system includes at least four internal heat sources 11 respectively disposed inside the cavity 20, used to simulate the internal heat generation during equipment operation; The environmental control module is located inside the housing 13 and is used to adjust the test environment inside the housing 13 in real time; The intelligent temperature monitoring module is used to simulate different test conditions for multi-material parallel testing by controlling the dynamic hot and cold flow field simulation module, the internal heat source 11 system and the environmental control module; and to collect relevant information from the cavity 20 and use the relevant information to analyze the cooling material to be tested. The test conditions include: outdoor lighting, airflow, internal heat generation during equipment operation, and the test environment inside the casing 13.

[0030] Furthermore, each cavity 20 is composed of multiple retractable and detachable heat insulation panels 19 spliced ​​together to form a cubic structure; The heat insulation panels 19 are connected by magnetic snap-fit ​​4, which facilitates quick disassembly and assembly.

[0031] Specifically, the material of the insulation board 19 may be, but is not limited to, polystyrene foam board, in order to reduce heat loss and meet the requirements for thermal insulation performance.

[0032] It should be noted that the cavity 20, which consists of multiple detachable heat insulation plates 19, is size-adjustable and can adapt to cooling material samples of different sizes through a telescopic structure. The size of the cavity 20 and the position of the sample can be quickly adjusted by manually adjusting the telescopic structure and the magnetic buckle 4, thus providing a simple and detachable structural module.

[0033] Furthermore, the dynamic thermal flow field simulation module includes: a movable slide rail 1, an infrared light source assembly 2, a hot / cold air circulation system, a light source controller 3, and a wind speed controller 8; The movable slide rail 1 is located at the top of the housing 13; The infrared light source component 2 is located below the movable slide rail 1 and is used to simulate different types of outdoor lighting at various angles by sliding on the movable slide rail 1. The hot / cold air circulation system is connected to the inside of the outer casing 13 through pipes to simulate airflow. The light source controller 3 is located outside the housing 13 and is connected to the infrared light source assembly 2. It is used to control the heating power, illumination time and moving speed of the infrared light source assembly 2 on the slide rail. The wind speed controller 8 is located outside the housing 13 and is connected to the hot / cold air circulation system to control the wind speed of the hot / cold air circulation system.

[0034] Furthermore, an air inlet 7 is provided on the upper side of the inner side of the outer casing 13, and an air outlet 6 is provided on the lower side of the inner side of the outer casing 13 corresponding to the side where the air inlet 7 is located. The hot / cold air circulation system is connected to the air supply outlet 7 and the air outlet 6 through pipes.

[0035] It should be noted that the air inlet 7 is located on the upper side of the inner side of the housing 13, and the air outlet 6 is located on the lower side of the inner side of the housing 13 corresponding to the side where the air inlet 7 is located. This is to combine the hot / cold air circulation system to form a bottom-up hot and cold air flow field. The power, irradiation time, and angle are flexibly set by the light source controller 3, and the wind speed controller 8 controls the cold and hot air at different speeds, thereby simulating different lighting conditions and airflow patterns (e.g., 1000W / m² on a sunny summer day). 2 Winter, mostly cloudy, 600W / m 2 The adjustable wind speed range of the hot air circulation system is 0.5 m / s to 8 m / s, covering typical wind speed conditions from natural breezes to forced ventilation; the adjustable wind speed range of the cold air circulation system is also 0.5 m / s to 8 m / s, covering typical wind speed conditions from natural breezes to forced ventilation. For example, when simulating natural ventilation in summer, the wind speed is typically set to 0.5 m / s to 1.5 m / s, for light winds it is set to 1.5 m / s to 4 m / s, and for strong winds it can be set to 5-8 m / s; while when simulating forced ventilation in winter it can be set to 2 m / s to 5 m / s, and for strong winds it can be set to 5-8 m / s. Through the light source controller 3 and the wind speed controller 8, the wind speed parameter can be coordinated with the power, irradiation time, and angle to achieve comprehensive simulation and coordinated control of multiple parameters, ensuring the stability and accuracy of the test conditions. The indoor testing device for cooling materials provided by this invention can quickly, efficiently, and accurately test the heat dissipation performance of cooling materials indoors. In particular, it can simulate hot air convection and cold air convection under conditions of high temperature in summer and low temperature in winter, so as to more comprehensively evaluate the performance of cooling materials.

[0036] This invention ensures the uniformity and stability of wind speed distribution by having the wind speed controller 8 work in conjunction with the hot / cold air circulation system, thus avoiding excessively high or low wind speeds in certain areas. In some embodiments, the wind speed sensor 17 may be, but is not limited to, a hot-wire anemometer or an ultrasonic anemometer 17.

[0037] Furthermore, the internal heat source 11 system also includes: a heat source controller 12; Each internal heat source 11 is used to simulate the internal heat generation during equipment operation; The heat source controller 12 is connected to each internal heat source 11 and is used to adjust the heating power of the internal heat source 11.

[0038] Furthermore, the internal heat source 11 is a heating wire, a heating plate, or a PTC heating element.

[0039] Furthermore, the environmental control module includes: a wireless temperature and humidity sensor 16, a heating / cooling device 15, a humidification / dehumidification device 5, and a wireless temperature and humidity controller 10; The wireless temperature and humidity sensor 16, the heating / cooling device 15 and the humidifying / dehumidifying device 5 are respectively disposed on the side inside the housing 13, and the wireless temperature and humidity controller 10 is disposed on the outside of the housing 13. The wireless temperature and humidity sensor 16 is used to monitor the temperature and humidity of the test environment inside the housing 13 and send the temperature and humidity of the test environment to the wireless temperature and humidity controller 10. The wireless temperature and humidity controller 10 is used to control the heating / cooling device 15 according to the temperature of the test environment to maintain the temperature of the test environment at a preset temperature; and to control the humidification / dehumidification device 5 according to the humidity of the test environment to maintain the humidity of the test environment at a preset humidity.

[0040] In some embodiments, the temperature sensor may be, but is not limited to, a thermocouple, a thermistor (RTD), or an infrared temperature sensor; the humidity sensor may be, but is not limited to, a capacitive humidity sensor or a resistive humidity sensor.

[0041] Furthermore, the wireless temperature and humidity controller 10 is specifically used for: When the temperature of the test environment is lower than the preset temperature, the temperature of the test environment is increased by controlling the heating / cooling device 15 until the temperature of the test environment equals the preset temperature, and then the operation stops. When the temperature of the test environment is higher than the preset temperature, the temperature of the test environment is reduced by controlling the heating / cooling device 15 until the temperature of the test environment is equal to the preset temperature, and then the operation stops. When the humidity of the test environment is lower than the preset humidity, the humidity of the test environment is increased by controlling the humidification / dehumidification device 5 until the humidity of the test environment equals the preset humidity, and then the operation stops. When the humidity of the test environment is greater than the preset humidity, the humidity of the test environment is reduced by controlling the humidification / dehumidification device 5 until the humidity of the test environment equals the preset humidity, and then the operation stops.

[0042] The environmental control module provided by this invention can monitor environmental parameters in real time. By setting temperature and humidity parameters, it ensures that the test environment temperature is stable within the range of high temperature in summer (30-40℃) and low temperature in winter (-15-5℃), and the humidity is controlled between 20% and 80%.

[0043] Furthermore, the intelligent temperature monitoring module includes: a wind speed sensor 17, at least two infrared thermal imagers 14, multiple thermocouple temperature sensors 9, and a control unit 18; The wind speed sensor 17 is located on the side inside the housing 13 to collect the wind speed inside the housing 13 and send the wind speed inside the housing 13 to the control unit 18. Two infrared thermal imagers 14 are respectively located inside the housing 13 at the top, and the two infrared thermal imagers 14 are diagonally distributed to collect the temperature of the outer surface of each cavity 20 and send the temperature of the outer surface of each cavity 20 to the control unit 18. Thermocouple temperature sensors 9 are set in a five-point manner on the sun-facing and shaded sides inside each cavity 20 to collect the temperature of the sun-facing and shaded sides and send the temperature of the sun-facing and shaded sides to the control unit 18. The control unit 18 is used to simulate different test conditions for multi-material parallel testing by controlling the dynamic hot and cold flow field simulation module, the internal heat source 11 system and the environmental control module; and to analyze the cooling material under test by using the wind speed inside the shell 13, the temperature on the sunny side, the temperature on the shady side and the temperature of the outer surface of each cavity 20. Among them, the wind speed inside the outer shell 13, the temperature on the sunny side, the temperature on the shady side, and the temperature of the outer surface of each cavity 20 are relevant information of the cavity 20.

[0044] In some embodiments, the thermocouple temperature sensors 9 may be connected to the control unit 18 via a data transmission line, but not limited to this. The thermocouple temperature sensors 9 are evenly distributed on the sun-facing and shaded sides of the cavity 20, using a five-point layout to ensure comprehensive temperature data acquisition. Two infrared thermal imagers 14 are diagonally distributed. Temperature data is transmitted in real-time to a computer for analysis via a data acquisition unit to ensure testing accuracy.

[0045] Understandably, the thermocouple temperature sensor 9 can collect real-time temperature values ​​at various monitoring points on the sun-facing and shaded sides of the cavity 20, generating a temperature change curve based on the real-time temperature values ​​and recording the temperature change trend over time. The infrared thermal imager 14 can collect temperature distribution images on the surface of the cavity 20, displaying temperature gradients and hotspot locations, and generating a temperature distribution thermal map through image analysis software to intuitively reflect the performance of the cooling material.

[0046] This invention utilizes dynamic hot and cold flow field simulation, a simple and detachable structure, an environmental control module, and an intelligent temperature monitoring module to achieve rapid sample replacement, parameter adjustment, and switching between multiple test modes, thereby improving testing efficiency and accuracy. In particular, by introducing hot and cold air circulation systems, it simulates hot and cold air convection under high summer and low winter conditions, more realistically reflecting the performance of cooling materials in practical applications. This solves the problems of long testing cycles, significant susceptibility to environmental factors, and poor repeatability in existing technologies.

[0047] Furthermore, the control unit 18 includes: The simulation module is used to control the dynamic thermal flow field simulation module by controlling the light source controller 3 and the wind speed controller 8, to control the internal heat source 11 system by controlling the heat source controller 12, and to control the environmental control module by controlling the wireless temperature and humidity controller 10, so as to simulate different test conditions for multi-material parallel testing. The data processing module is used to preprocess relevant information to obtain processed relevant information; The data analysis module is used to analyze the tested cooling material using the processed relevant information.

[0048] In some embodiments, the control unit 18 is also used to store relevant information, for example, to store the relevant information locally or in the cloud for later retrieval and analysis.

[0049] The control unit 18 in the intelligent temperature monitoring module serves as the core control module of the entire testing device. It connects with devices such as the light source controller 3, wind speed controller 8, temperature controller, humidity controller, wind speed sensor 17, infrared thermal imager 14, and high-precision thermocouple temperature sensor 9 to achieve precise control and real-time monitoring of the testing environment. Through the coordinated operation of the control unit 18 in the intelligent temperature monitoring module, the efficiency and accuracy of the testing process are ensured, while real-time monitoring and feedback control are also achieved.

[0050] In some embodiments, the control unit 18 may be connected to other devices and modules via data transmission lines, but not limited to. For example, the thermocouple temperature sensor 9 transmits temperature data to the control unit 18 in real time via a data transmission line; the infrared thermal imager 14 transmits temperature distribution image data to the control unit 18 in real time via a data transmission line.

[0051] Furthermore, the data processing module is specifically used for: The relevant information is filtered, denoised, and calibrated, and abnormal data in the relevant information is marked or removed to obtain the processed relevant information, so as to ensure the accuracy and reliability of the data.

[0052] Furthermore, the data analysis module includes: The first generation submodule is used to generate temperature change curves for each cavity 20 using the temperature of the outer surface of each cavity 20, and calculate the slope of the temperature change curves. When the slope is less than or equal to the slope threshold, the time point corresponding to the slope is the temperature equilibrium time. The second generation submodule is used to determine the average temperature difference inside each cavity 20 by using the temperature of the sun-facing side and the temperature of the shaded side, and to generate an average temperature difference curve using the average temperature difference, and to calculate the standard deviation using the average temperature difference. The third generation submodule is used to generate wind speed change curves by utilizing the wind speed inside the shell 13 at each time point. The fourth generation submodule is used to overlay the wind speed change curve with the temperature change curve and the average temperature difference curve, respectively, to generate the temperature change curve after overlaying the wind speed change curve and the average temperature difference curve after overlaying the wind speed change curve. The analysis submodule is used to evaluate the performance of the cooling material under test based on the first preset rule, according to the temperature equilibrium time and standard deviation; and to analyze the influence of wind speed on the performance of the cooling material under test based on the second preset rule, according to the temperature change curve after superimposing the wind speed change curve and the average temperature difference curve after superimposing the wind speed change curve.

[0053] Furthermore, the second generation submodule is specifically used for: The average temperature of the sunny side is calculated using the temperature of the sunny side. The average temperature of the shaded side is calculated using the temperature of the shaded side. The difference between the average temperature on the sunny side and the average temperature on the shady side is called the average temperature difference.

[0054] For example, (1) Data acquisition: Temperature data of the sun-facing and shaded sides of the cavity 20 are collected in real time by thermocouple temperature sensor 9 and infrared thermal imager 14. Control unit 18 records temperature values ​​at fixed time intervals (such as per second or per minute) and stores them as time series data.

[0055] (2) Data processing: The collected temperature data is preprocessed, including filtering, denoising (e.g., using filtering algorithms) and calibrating the relevant information, and marking or removing abnormal data in the relevant information (e.g., using statistical methods) to obtain the processed relevant information.

[0056] Calculate the average temperature difference at each time point: ΔT = T 向阳面 -T 背阴面 In the above formula, ΔT is the average temperature difference inside each cavity 20, and T 向阳面 T represents the average temperature of the sunny side. 背阴面 This represents the average temperature on the shaded side.

[0057] (3) Curve drawing: Use data analysis software (such as Python's Matplotlib, Excel, or MATLAB) to plot the curve. The horizontal axis represents time, and the vertical axis represents temperature or the difference between average and average temperatures.

[0058] The temperature change curves and average temperature difference curves of the sunny and shady sides are plotted on the same graph for easy comparison and analysis.

[0059] (4) Evaluate the performance of cooling materials 1) Locate the point where the temperature stabilizes from the temperature-time curve. This involves calculating the slope of the temperature change. When the slope is less than a certain threshold (e.g., 0.01°C / s), the temperature is considered to have reached equilibrium, and the equilibrium time is calculated. A shorter equilibrium time indicates a rapid response from the cooling material, suitable for handling instantaneous thermal shocks; a longer equilibrium time indicates thermal stability from the cooling material, suitable for smoothing temperature fluctuations and achieving time delays.

[0060] 2) Generate an average temperature difference curve using the average temperature difference, calculate the standard deviation using the average temperature difference, and obtain the fluctuation range of the average temperature difference. The smaller the standard deviation, the better the uniformity of the cooling material.

[0061] Calculate the temperature drop at the start and end of the test using the following formula: Δ Tefficiency = T 初始 -T 最终 .

[0062] In the above formula, Δ Tefficiency For the temperature drop, T 初始 The temperature at which the test begins, T 最终 The temperature at the end of the test.

[0063] It can also calculate the standard deviation of temperature on the sunny and shady sides or draw temperature fluctuation graphs to analyze the amplitude and frequency of temperature fluctuations.

[0064] 3) Combining hot air velocity and cold air velocity data, analyze the impact of wind speed on the performance of cooling materials, as shown below: Temperature data was aligned with hot and cold air velocity data by time to ensure data consistency and facilitate correlation analysis. Temperature change curves and average temperature difference curves under different wind speed conditions were compared to analyze temperature data within different wind speed ranges in groups.

[0065] The effect of wind speed on temperature equilibrium time: Calculate the temperature equilibrium time under different wind speed conditions and plot the relationship between wind speed and equilibrium time.

[0066] The effect of wind speed on cooling efficiency: Calculate the cooling efficiency under different wind speed conditions and draw a graph showing the relationship between wind speed and cooling efficiency.

[0067] The effect of wind speed on stability: Calculate the standard deviation of temperature fluctuation under different wind speed conditions and plot the relationship between wind speed and stability.

[0068] The above-mentioned analytical processes can be implemented, but are not limited to, through the collaborative work of control unit 18, various sensors, and data analysis software (such as Python, Excel, or MATLAB), providing a scientific basis for the performance evaluation and optimization of cooling materials.

[0069] To further illustrate the above-mentioned indoor testing device for cooling material performance, the present invention provides examples of practical applications of the device, as shown below: Sample preparation: If the cooling material to be tested is a coating, the surface of the heat insulation board 19 can be pretreated by spraying the coating evenly and curing it; if it is a film, it can be directly applied to the surface of the cavity 20; fix the sample on the surface of the cavity 20 to ensure good contact with the temperature sensor.

If it is a thin film, the cooling film is directly and smoothly adhered to the surface of the cavity 20 using an adhesive method. A wireless temperature sensor is placed on the outer surface of the material to be tested.

Test run: Start the simulated heat source and heat continuously for 2-4 hours, collecting temperature data of the sun-facing and shaded sides in real time; monitor and adjust the wind speed in real time through the wind speed controller 8 to ensure the uniformity and stability of the wind speed distribution. Data analysis: Plot temperature change curves and average temperature difference curves over time to evaluate the performance of cooling materials (such as temperature equilibrium time, uniformity, etc.); combine hot air velocity and cold air velocity data to analyze the impact of wind speed on the performance of cooling materials.
