Description

Technical Field

[0001] This invention relates to a testing device, and more particularly to a testing device and method for testing the thermal conductivity efficiency of thermal grease, belonging to the field of thermal grease performance testing technology. Background Technology

[0002] Thermal grease is a high-performance thermally conductive medium made primarily of silicone, with added heat-resistant and highly conductive materials. It possesses excellent thermal conductivity, electrical insulation, resistance to high and low temperatures, weather resistance, and stability. It is widely used in electronics, electrical engineering, machinery, and aerospace to fill gaps between components, forming heat conduction channels and accelerating heat transfer and dissipation. With the continuous development of electronic technology, the application prospects of thermal grease will further expand, making it an indispensable heat dissipation material in modern industry.

[0003] The existing technology for testing the thermal conductivity efficiency of thermal grease has the following main technical problems that need to be solved: I. Technical Issues of the Detection Device Accuracy and stability: Accuracy: The thermal conductivity of thermal grease is typically between 1 and 5 W / (m·K), or even wider. Therefore, the testing device needs to be able to accurately measure the thermal conductivity within this range, and the error should be as small as possible.

[0004] Stability: The testing equipment should maintain stable performance during operation and should not be affected by external environmental factors such as temperature and humidity.

[0005] Applicability and compatibility: Because thermal greases have different physical properties (such as viscosity and flowability), the testing device needs to be able to adapt to different types of thermal greases to ensure the accuracy and reliability of the test.

[0006] The testing equipment should be able to handle samples of different shapes and sizes in order to conduct a wider range of tests.

[0007] Ease of use and safety: Ease of operation: The operation of the testing device should be as simple as possible to reduce the difficulty of operation and improve the testing efficiency.

[0008] Safety: During the testing process, the safety of the operators should be ensured to avoid accidents.

[0009] II. Technical Issues with Detection Methods Reliability of the test principle: Commonly used testing methods include the steady-state heat flux method and the transient planar heat source method (TPS). Each method has its advantages and disadvantages, and the appropriate testing method should be selected based on the specific application scenario.

[0010] For example, while the steady-state heat flow method is accurate, it is complex to operate and has a long measurement cycle; the transient plane heat source method is simpler, but it may be affected by factors such as contact thermal resistance.

[0011] Control of test parameters: The testing process requires controlling multiple parameters, such as temperature, pressure, and time. The selection and control of these parameters have a significant impact on the accuracy of the test results.

[0012] For example, a constant temperature environment needs to be maintained during the testing process to avoid the impact of temperature fluctuations on the test results.

[0013] Repeatability of test results: To ensure the reliability of the test results, multiple repeated tests are required, and the repeatability of the test results needs to be verified.

[0014] Poor repeatability may indicate a problem with the testing method or equipment, requiring improvement.

[0015] Simulation of the practical application of thermal grease: Thermal grease is affected by various factors in practical applications, such as pressure, temperature gradient, and surface roughness. Therefore, it is necessary to simulate these real-world application conditions as closely as possible during testing to obtain more accurate test results.

[0016] After thermal grease is manufactured, its thermal conductivity efficiency needs to be tested to determine if the product meets standards. Existing thermal conductivity testing devices generally have low levels of automation. For example, a known invention (CN217304986U) discloses a device for testing the thermal conductivity performance of thermal grease, comprising a base, a lower support plate, a first temperature sensor, an upper support plate, a second temperature sensor, a top plate, a guide rod, a test frame, a lower heat-conducting plate, an electric heating plate, an upper heat-conducting plate, a screw sleeve, and a screw. In use, thermal grease is applied to the test frame, and the screw is rotated to move the upper support plate downwards until the upper heat-conducting plate contacts the thermal grease. The electric heating plate is then energized to heat the upper heat-conducting plate. The temperature changes of the first and second temperature sensors at different times are observed on a display. This data allows for the testing and analysis of the thermal conductivity efficiency of the thermal grease. Because existing thermal conductivity testing devices have a low degree of automation, they cannot automatically complete continuous testing. Staff need to manually operate the device, clean it, and repeat the testing process after completing the testing. This makes it cumbersome for staff to test multiple samples. Therefore, a thermal conductivity testing device and method for thermal grease is proposed. Summary of the Invention

[0050] In this embodiment, specifically: in step four, the second motor 42 drives the second lead screw 43 to rotate, thereby driving the slide rod 44, support rod 45 and scraper 46 to move.

The first motor 21 drives the first lead screw 22 to rotate, causing the slider 23, support plate 24, and the storage tank on top of the support plate 24, along with the pipeline, to move together until the outlet 213 reaches above the temperature detector 35. At this point, one of the second electric valves 29 opens, activating the pump 211 to deliver the silicone grease sample into the testing frame 37. The feeding assembly 20 resets, and the hydraulic cylinder 15 drives the heating plate 16 to contact the silicone grease and heat it. The control panel 110 determines the thermal conductivity of the silicone grease by comparing the temperature of the heating plate 16 with the temperature detected by the temperature detector 35. After the test is completed, the hydraulic cylinder 15 is reset, and the first water inlet pipe 27 and the second water inlet pipe 47 are used to send in cleaning fluid.

During the rinsing process, the second motor 42 drives the second lead screw 43 to rotate, so that the slide bar 44 and the parts fixed on the slide bar 44 move together. The scraper 46 is used to scrape off the residual cleaning fluid. After cleaning, the second electric valve 29 is replaced to replace the sample.
