[0022] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] Please see Figures 1-4 The present invention discloses a thermal grease oil separation performance testing device, including a base 1 and a support part 2 disposed on the outside of the base 1. The inner side of the support part 2 is threadedly connected to a reciprocating lifting assembly 4. The inner side of the lifting assembly 4 is slidably connected to a pressure structure 6 for testing thermal grease. The inner side of the lifting assembly 4 is equipped with a return spring 7 for controlling the pressure of the pressure structure 6.

[0025] Please see Figure 2 A threaded hole 3 is provided in the center of the surface of the support part 2. A test platform 11 is integrally formed on the side of the base 1 near the support part 2. An arc-shaped protrusion is provided at the edge of the surface of the test platform 11. The arc-shaped protrusion on the surface of the test platform 11 can prevent thermal grease from leaking out of the test platform 11.

[0026] Please see Figure 4 The lifting assembly 4 includes a threaded sleeve 41, an inner cavity 42, and a movable hole 43. The threaded sleeve 41 is threadedly connected to the inner side of the threaded hole 3. The inner cavity 42 is a regular hexagon and is located inside the threaded sleeve 41. The center of the inner cavity 42 coincides with the axis of the threaded sleeve 41. The movable hole 43 is located in the center of the inner wall of the inner cavity 42 near the base 1. The regular hexagonal shape of the inner cavity 42 allows the slider 61 to slide vertically and also limits the slider 61. When the threaded sleeve 41 rotates, it can drive the pressure structure 6 to rotate together. When the threaded sleeve 41 rotates in the threaded hole 3 and the pressure structure 6 squeezes the thermal grease, the pressure structure 6 can rotate synchronously with the threaded sleeve 41. While squeezing the thermal grease, it can also rotate and act on the thermal grease, making it spread evenly to the surroundings more quickly.

[0027] Please see Figure 4The pressure structure 6 comprises a sliding block 61 and a punch head 62, the sliding block 61 is slidingly connected to the inner side of the inner cavity 42, the punch head 62 is fixedly connected to the side of the sliding block 61 close to the base 1, the punch head 62 penetrates the movable hole 43 and is attached to the test table 11, the punch head 62 is hollow, the punch head 62 is made of high borosilicate glass, the high borosilicate glass is a transparent material, the punch head 62 made of high borosilicate glass can have enough hardness to extrude the heat-conducting silicone grease and does not affect the observation of the heat-conducting silicone grease by the staff.

[0028] Please refer to Figure 3 The reset spring 7 is installed between the sliding block 61 and the inner wall of the inner cavity 42 and is attached to the inner wall of the inner cavity 42, when the threaded sleeve 41 is rotated in the threaded hole 3 to make the punch head 62 extrude the heat-conducting silicone grease, the punch head 62 will rotate together with the threaded sleeve 41 to extrude and spread the heat-conducting silicone grease, but the extrusion of the heat-conducting silicone grease cannot guarantee that the heat-conducting silicone grease is uniformly spread, the staff can continue to rotate the threaded sleeve 41 to adjust it downward, the punch head 62 will keep rotating to extrude the heat-conducting silicone grease, but the punch head 62 cannot move downward with the threaded sleeve 41, the reset spring 7 between the threaded sleeve 41 and the punch head 62 is extruded in the process of the downward movement of the threaded sleeve 41 and generates a rebound force acting on the punch head 62, so that the punch head 62 can generate a suitable pressure on the heat-conducting silicone grease, avoiding that the heat-conducting silicone grease is split due to excessive force or not completely spread.

[0029] Please refer to Figure 1 The surface of the threaded sleeve 41 away from the base 1 is fixedly connected with a handle 5.
