[0002] Thermal conductive gel is a flexible, highly thermally conductive material that is usually applied to the surface of various components to improve heat dissipation.

[0003] High-quality thermally conductive gel should have excellent flow properties. Good flow properties help it evenly cover the surface of components in actual applications, thereby achieving the best thermal conductivity. Therefore, during the production process, the flow properties of thermally conductive gel usually need to be tested. The current testing method generally places the thermally conductive gel in a standard container and measures the volume or distance it flows out within a specified time to evaluate its flow performance in actual use. However, in actual applications, thermally conductive gel is often applied to the surfaces of components with different roughness. The existing testing method cannot fully simulate the flow properties of the thermally conductive gel in actual use and has certain limitations.

[0004] In summary, this application proposes a performance testing device for thermal conductive gel production to improve the above-mentioned technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: A performance testing device for thermal conductive gel production, referring to Figures 1-6 As shown, it includes a base 1, a fixed rod 2 and an electric gripper 3; the base 1 is fixedly connected to two fixed rods 2; each fixed rod 2 is equipped with an electric gripper 3;

[0029] It also includes a cylinder 4, a recovery box 5, a test net 6 and a limit plate 7; the electric gripper 3 is connected to the cylinder 4, and the thermal conductive gel is added into the cylinder 4 from the upper port along its side wall, so that it flows downward along the inner wall of the cylinder 4, and the flow performance of the thermal conductive gel is detected by measuring the flow time and distance; a discharge hopper 42 is provided at the bottom of the cylinder 4; two recovery boxes 5 are bolted to the base 1, and the recovery boxes 5 are located below the discharge hopper 42; the cylinder 4 is detachably connected to the test net 6; four limit plates 7 distributed in a ring array are provided on the upper side of the test net 6.

[0030] It also includes a metal sheet 8 and an annular electromagnet 9; eight metal sheets 8 distributed in an annular array are fixed to the lower side of the test network 6; and an annular electromagnet 9 is arranged inside the cylinder 1 4.

[0031] It also includes an elastic membrane 101, a screw 102, a fixing frame 103 and a top block 104; three through holes are opened on the lower side of the cylinder 4, and an elastic membrane 101 is fixed in each through hole; a fixing frame 103 is fixed to each through hole; each fixing frame 103 is rotatably connected to a screw 102; each elastic membrane 101 is fixed to a top block 104, and the top block 104 is rotatably connected to the screw 102.

[0032] The elastic membrane 101 and the cylinder 1 4 are arranged to be detachably connected, and the elastic membrane 101 can be disassembled to facilitate subsequent cleaning and replacement.

[0033] It also includes an electric guide rail 10, an annular guide rail 111, an annular slider 112 and a limit frame 113; the annular guide rail 111 is installed on the outside of the cylinder 4; the annular guide rail 111 is rotatably connected to the annular slider 112; the annular slider 112 is fixedly connected to a number of limit frames 113, and the limit frames 113 correspond to the positions of the limit plates 7; the electric guide rail 10 is installed inside the cylinder 4, the electric guide rail 10 is rotatably connected to the slip ring, the slip ring is fixedly connected to the annular electromagnet 9, and the annular electromagnet 9 is rotatably connected to the cylinder 4.

[0034] Cylinder 1 4 is provided with an observation window 41 so that the staff can observe the flow of the thermal conductive gel.

[0035] The flow performance test steps of thermal conductive gel are as follows: a certain amount of thermal conductive gel is added into cylinder 1-4 from the upper port along its side wall, so that it flows from top to bottom inside cylinder 1-4, and the volume and distance of the thermal conductive gel flow are observed and measured through the observation window 41 within a specified time, so as to test its flow performance. The thermal conductive gel after the test is finally discharged through the discharge hopper 42 on the lower side of cylinder 1-4 and collected in the recycling box 5; however, thermal conductive gel is often applied to the surface of components with different roughness in actual application, and the existing detection method cannot fully simulate the flow performance of the thermal conductive gel under actual use, and has certain limitations; therefore, before the test, a test net 6 is manually placed into the interior of cylinder 1-4, and is clamped at the upper end of cylinder 1-4 by a limit plate 7, so as to limit and fix the inserted test net 6. At this time, the test net 6 is in contact with the inner wall of cylinder 1-4, and then a certain amount of thermal conductive gel is manually placed into the interior of cylinder 1-4, so that it flows downward along the inner wall of cylinder 1-4, and the cylinder is increased through the test net 6. The roughness of the inner wall of cylinder 4 is varied to simulate the flow properties of the thermally conductive gel under actual use. Furthermore, by replacing test nets 6 of different specifications, the roughness of the inner wall of cylinder 4 is varied to simulate the flow properties of the thermally conductive gel on surfaces of varying roughness, thereby improving the accuracy of the flow properties test. Furthermore, considering that the test net 6 is placed inside cylinder 4 and its bottom is not restricted, even if reinforcing ribs are provided on the test net 6, as the thermally conductive gel flows downward along the surface of the test net 6, the test net 6 may still deflect and deform, preventing the test net 6 from conforming to the inner wall of cylinder 4, thereby affecting the accuracy of the flow properties test of the thermally conductive gel. Therefore, a metal sheet 8 is provided on the underside of the test net 6. After the test net 6 is placed inside cylinder 4 and secured, the annular electromagnet 9 is connected to a power source, which magnetically attracts the metal sheet 8, causing the test net 6 to conform to cylinder 4, thereby preventing the test net 6 from deflecting and deforming during the test process, which could affect the accuracy of the flow properties test of the thermally conductive gel.

[0036] Furthermore, when the thermally conductive gel is applied to the surface of a component, the surface of the component is not completely flat, so the thermally conductive gel does not flow along the same path when flowing. Existing detection methods can only make the thermally conductive gel flow from top to bottom, and its detection results still have certain limitations. Therefore, when the thermally conductive gel flows downward in the cylinder 4, the screw 102 is manually rotated so that the screw 102 drives the top block 104 to move toward the inside of the cylinder 4. The top block 104 pushes the elastic membrane 101 toward the inside of the cylinder 4, thereby changing the flow path inside the cylinder 4. The lifting action of the elastic membrane 101 changes the flow path of the thermally conductive gel. The screw 102 is manually rotated, and the distance that the screw 102 drives the top block 104 to move adjusts the size of the lifting of the elastic membrane 101, thereby simulating the situation in which the thermally conductive gel flows along different paths when actually used, thereby improving the accuracy of the overall thermally conductive gel fluidity detection.

[0037] Furthermore, when the thermally conductive gel is applied between the components and the radiator, in actual use, the components may vibrate or move, causing the thermally conductive gel to be subjected to additional external forces during actual use. Therefore, when the test net 6 is placed in the cylinder 4, the limit plate 7 is simultaneously inserted between the limit frame 113. When the thermally conductive gel flows downward along the inner wall of the cylinder 4 to which the test net 6 is added, the annular guide rail 111 is controlled to drive the annular slider 112 and the limit frame 113 to repeatedly rotate forward and reverse. The limit frame 113 drives the test net 6 to repeatedly rotate forward and reverse through the limit plate 7, causing the test net 6 to rotate repeatedly, thereby applying disturbance to the flowing thermally conductive gel, thereby simulating that the thermally conductive gel will be subjected to additional external forces during the flow process, thereby improving the accuracy of the thermal conductive gel fluidity detection. It should be noted that when controlling the rotation of the annular slider 112, the electric guide rail 10 is synchronously controlled to drive the annular electromagnet 9 to rotate, and the annular electromagnet 9 drives the lower side of the test net 6 to rotate synchronously through the metal sheet 8, ensuring the stability of the test net 6 during rotation.

[0038] Example 2: Based on Example 1, Figure 3-Figure 5 As shown, the limit plate 7 is rotatably connected to the test net 6, and the discharge hopper 42 is detachably connected to the cylinder 1 4. After the discharge hopper 42 is removed, the test net 6 can be taken out from the cylinder 1 4 from top to bottom, thereby preliminarily scraping off the thermal conductive gel remaining on the inner wall of the cylinder 1 4 for subsequent cleaning.

[0039] It also includes a counterweight ball 121; each limiting plate 7 is fixedly connected to a counterweight ball 121.

[0040] On the basis of the above embodiment 1, after the thermal conductive gel is tested, a large amount of thermal conductive gel will adhere to the inner wall of the cylinder 1 4 due to its certain adhesiveness, making subsequent cleaning difficult. Therefore, after the test is completed, the limit plate 7 is manually rotated, as shown in FIG. Figure 5 As shown, after the limit plate 7 is rotated to the middle of the test net 6, the power supply of the annular electromagnet 9 is disconnected, the magnetic attraction of the metal sheet 8 is stopped, and the test net 6 loses its fixing effect. Then the discharge hopper 42 is manually disassembled and opened, and a counterweight ball 121 is provided on the limit plate 7. When the limit plate 7 is rotated to the middle of the test net 6, the gravity of the counterweight ball 121 causes the test net 6 to automatically slide down along the inner wall of the cylinder 4 and be taken out. The test net 6 is moved and taken out, and the thermal conductive gel remaining on the inner wall of the cylinder 4 is preliminarily scraped off to facilitate subsequent cleaning.

[0041] Example 3: Based on Example 2, Figure 1 and Figure 6 As shown, a DD motor 201 is also included; each fixing rod 2 is fixedly connected to a DD motor 201, and the rotating part of the DD motor 201 is fixedly connected to the electric gripper 3.

[0042] It also includes a second cylinder 202; the electric gripper 3 is connected to the second cylinder 202, and the inner wall of the second cylinder 202 is set to be smooth.

[0043] At the same time, in the process of detecting the flow properties of the thermal conductive gel, the electric gripper 3 is driven by the DD motor 201 to drive the cylinder 1 4 to rotate to adjust its inclination angle, so that the flow properties of the thermal conductive gel at different angles can be detected; and a cylinder 202 is also provided. During the detection process, the same amount of thermal conductive gel is placed in the cylinder 2 202 at the same time. By comparing the flow properties of the thermal conductive gel in the cylinder 1 4 and the cylinder 2 202 respectively, the reliability of the overall thermal conductive gel detection is improved.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
