Description

Technical Field

[0001] The utility model relates to the technical field of thermal conductive silicone sheet detection, in particular to a thermal conductive silicone sheet tensile strength detection mechanism. Background Art

[0002] Thermally conductive silicone sheet is a kind of thermal conductive medium material synthesized by special process with silicone as base material and various auxiliary materials such as metal oxides. It is also called thermal conductive silicone pad, thermal conductive silicone sheet, soft thermal conductive pad, thermal conductive silicone gasket, etc. in the industry. This material is specially produced for the design scheme of transferring heat through gaps. It can fill the gaps and open up the heat channel between the heating part and the heat dissipation part, effectively improving the heat transfer efficiency. The main characteristics of thermally conductive silicone sheet include insulation, thermal conductivity and heat dissipation, wear resistance, flame retardancy, gap filling, compression resistance, buffering, etc. Its heat dissipation principle is to quickly export the heat of the heating element through the high thermal conductivity of the silicone base material, thereby achieving the purpose of thermal conduction and heat dissipation.

[0003] The tensile strength test of thermally conductive silicone sheets is one of the important steps in evaluating their mechanical properties. Tensile strength refers to the tensile stress applied to the sample to cause it to break, which is a reflection of the strength and toughness of the product. Usually, a thermally conductive silicone sheet tensile strength tester is required to stretch the thermally conductive silicone sheet, record the test results, and perform data processing and analysis. Calculate the tensile strength of the sample and compare and evaluate it with other performance indicators.

[0004] When conducting a tensile strength test on a thermally conductive silicone sheet, it is necessary to prepare samples, select samples from the same batch of thermally conductive silicone sheets, and cut the samples according to certain standards, so that the prepared samples can be conveniently placed in the fixture of the testing machine and fastened so that the samples will not fall off or move during the test. However, the cutting process usually requires staff to manually cut the thermally conductive silicone sheet, which consumes a lot of time. In view of this, the present application proposes a tensile strength testing mechanism for a thermally conductive silicone sheet. Utility Model Content
