Description

Technical Field

[0001] This utility model relates to the field of silicone thermal conductive sheet technology, and more specifically, to a silicone thermal conductive sheet structure. Background Technology

[0002] Silicone thermal conductive sheets are thermally conductive media synthesized from silicone as the base material and with the addition of materials such as metal oxides. They are mainly used for heat transfer between heat-generating components and heat-dissipating parts in electronic and electrical equipment. This material has flexibility and insulation, and its surface adhesiveness can fill mechanical gaps and adapt to the design requirements of miniaturized equipment. It optimizes heat dissipation efficiency by reducing the thermal resistance of the connection surface, while also having functions such as shock absorption and sealing.

[0003] Silicone thermal pads are attached to product surfaces via self-adhesive. However, some existing silicone thermal pad materials are relatively soft. When users peel off the surface film of the self-adhesive layer during installation, the thermal pads may wrinkle or stick together, hindering subsequent installation. Therefore, we have proposed a new silicone thermal pad structure. Utility Model Content

The conductive block not only conducts heat but also increases the toughness of the silicone sheet body. When assembling the silicone layer and the conductive block, the user places the two silicone layers on the top and bottom of the conductive block, and then passes the positioning rod through the positioning hole opened inside the silicone sheet body. The first stop installed on the top of the positioning rod can prevent the positioning rod from falling. Then, the user engages the plug installed on the top of the second stop with the slot opened at the bottom of the positioning rod to fix the second stop. Through the cooperation of the first stop, the positioning rod, the second stop, and the plug, the silicone layer and the conductive block can be assembled.

[0011] By adopting the above technical solution, the silicone layer is composed of a base layer, a thermally conductive layer, a reinforcing layer, a buffer layer, a flame-retardant layer, and a wear-resistant layer. The thermally conductive layer helps to increase the product's thermal conductivity. The reinforcing layer helps to increase the product's thermal toughness. The buffer and flame-retardant layers can buffer and increase the product's flame-retardant effect.
