[0002] "Thermal conductive silicone sheet" is a thermal conductive medium material that is synthesized through a special process with silicone as the base material and various auxiliary materials such as metal oxides added. In the industry, it is also called thermal conductive silicone pad, thermal conductive silicone sheet, soft thermal conductive pad, thermal conductive silicone gasket, etc. It is specially produced for the design of transferring heat through gaps. It can fill the gaps, open up the heat channel between the heating part and the heat dissipation part, and effectively improve the heat transfer efficiency. At the same time, it also plays the role of insulation, shock absorption, sealing, etc. It can meet the design requirements of miniaturization and ultra-thinness of equipment. It is highly processable and practical, and has a wide range of applicable thicknesses. It is an excellent thermal conductive filling material.

[0003] In the process of producing thermally conductive silicone gaskets, in order to ensure the thermal conductivity of the thermally conductive silicone gaskets, it is necessary to use a thermal conductivity detection device to test the thermal conductivity of the thermally conductive silicone gasket samples. The existing precise thermal conductivity detector for thermally conductive silicone gaskets does not have a protective function, which causes the detector to be easily damaged by accidental impact during idleness or transportation, which is not conducive to the use of staff. For this reason, we propose a precise thermal conductivity detector for thermally conductive silicone gaskets. Utility Model Content
