Technical Field
[0001] The utility model relates to the technical field of heat-conducting silicone rubber gaskets, in particular to a heat-conducting silicone rubber gasket with high installation precision. Background Art
[0002] Electronic components are the basis of electronic products. Understanding the types, structures, and performance of commonly used electronic components and being able to choose them correctly is the basis for learning and mastering electronic technology. When using them, in order to avoid damage caused by overheating, thermal conductive silicone rubber gaskets are usually used to dissipate heat and protect them at the same time.
[0003] Existing technology N218735704U, this patent proposes a high thermal conductivity insulating silicone rubber gasket, which can be used for the installation of electronic components through the cooperation of the provided silicone rubber matrix, frame-type rubber pad, plate-type thermal conductive silicone, through-hole, sealing film sleeve, columnar thermal conductive silicone and aluminum particles. The silicone rubber matrix is combined with the frame-type rubber pad to meet the installation insulation requirements of electronic components. The plate-type thermal conductive silicone can be used for both bonding and fixing, and heat conduction. The combination of columnar thermal conductive silicone and aluminum particles can greatly improve the thermal conductivity efficiency and have a good thermal conductivity effect. The provided thermal conductive graphite film can be used to enclose and seal multiple through-holes to prevent leakage of columnar thermal conductive silicone and aluminum particles. Moreover, the thermal conductive graphite film itself has excellent thermal conductivity, which can assist in the heat transfer between the plate-type thermal conductive silicone and the columnar thermal conductive silicone, and further improve the thermal conductivity efficiency.
[0004] The prior art generally uses a thermally conductive silicone rubber gasket for use, but after installation, the contact between the gasket and the surface of the electronic component is poor, and there may be a cavity at the joint between the two, resulting in poor installation accuracy.
