[0002] Thermal conductive sheets have the effects of heat conduction and insulation, and are used between heating devices and heat sinks or metal bases. After the thermal conductive sheets are produced, in order to ensure their use, the power performance of the thermal conductive sheets needs to be tested. In current life, the power performance of thermal conductive sheets is tested through a thermal conductivity tester, such as the SC-DRS2 thermal conductivity tester.

[0003] The thermal conductivity tester in the prior art still has certain defects. After testing the thermal conductive sheet with the thermal conductivity tester, the personnel need to release the pressing plate and then manually unload the material, which requires the personnel to operate multiple times, affecting the test effect of the thermal conductive sheet and causing high labor intensity for the personnel. Based on this, the utility model designs a device for testing the power of a composite thermal conductive sheet to solve the above problems. Utility Model Content

[0027] The outer diameter of the slider is equal to the inner diameter of the slide groove 13, and the two sliders are installed at one end of the protective box 14 to ensure the stability of the movement of the protective box 14 and avoid the problem of the protective box 14 falling off. The protective box 14 is slidably connected to the inner surface of the slide groove 13. One end of the protective box 14 is evenly installed with spring telescopic rods 15 through screws. The bottoms of several spring telescopic rods 15 are connected by a mounting frame 16. A cleaning cylinder 17 is rotatably connected to the inside of the mounting frame 16. An operation screen is provided at one end of the thermal conductivity tester body 1. The outer side of the cleaning cylinder 17 is in contact with the operation screen, which is convenient for cleaning the operation screen. A fixing groove 18 is provided at one end of the top of the thermal conductivity tester body 1. The position of the fixing groove 18 corresponds to the position of the cleaning cylinder 17, which is convenient for placing the cleaning cylinder 17 and fixing the protective box 14.

[0028] When a person is using the thermal conductivity tester body 1, he moves the protective box 14 to drive the cleaning cylinder 17 to move. Through the squeezing of the spring telescopic rod 15, the cleaning cylinder 17 can contact the operation screen to clean the operation screen, which makes it easier for the person to watch the operation screen. After the protective box 14 is moved to a certain position, the spring telescopic rod 15 stretches to push the cleaning cylinder 17 to move into the fixing groove 18, thereby fixing the cleaning cylinder 17 and fixing the protective box 14.

[0029] The personnel places two thermal conductive sheets on the top and bottom of the probe 2, and then rotates the threaded rod 4 to drive the extrusion plate 5 to move, fix the two thermal conductive sheets, and then turn on the thermal conductivity tester body 1 to test the power of the thermal conductive sheet, and then turn on the electric telescopic rod 7 to drive the gear rod 8 to move, so that the gear rod 8 is meshed with the gear 12. As the power test of the thermal conductive sheet is completed, the threaded rod 4 is rotated again to drive the extrusion plate 5 to move, and the movement of the extrusion plate 5 drives the gear rod 8 to move, and then drives the gear 12 to rotate, and the rotation of the gear 12 drives the long screw rod 10 to rotate, and the rotation of the long screw rod 10 drives the push plate 11 to move, and the thermal conductive sheet at the top of the mounting bracket 3 is unloaded. As the extrusion plate 5 moves, the gear 12 is not meshed with the gear rod 8. At this time, the reset spring 9 is reset, causing the long screw rod 10 to rotate in the opposite direction, and then the push plate 11 is reset, which is convenient for the subsequent power test of the thermal conductive sheet. During the reset process of the long screw rod 10, the electric telescopic rod 7 is turned on again, so that the gear rod 8 and the gear 12 are staggered.
