Abstract

The invention provides a wear-resistant highly heat-conducting sheet and application thereof and relates to a heat-conducting material. The wear-resistant highly heat-conducting sheet comprises a heat-conducting layer which is located above and is made of a heat-conducting material with a heat conductivity coefficient larger than 2 W/m-K, and a wear resistant layer which is located below and is made of a wear resistant material with a heat conductivity coefficient larger than 0.3 W/m-K, and the wear resistant layer is fixed under the heat-conducting layer. The wear resistance performance is improved by the wear resistant layer, and at the same time the heat-conducting layer protected by the wear resistant layer is used to improve interface thermal resistance. A plugging resistant connectorwith the wear-resistant highly heat-conducting sheet is the application of the wear-resistant highly heat-conducting sheet in the connector.

Description

technical field [0001] The invention relates to materials, in particular to a thermally conductive material. Background technique [0002] With the upgrading of communication networks, the optical communication industry requires higher and higher data transmission volumes, and with the popularization of laser chip-level applications, the specifications of optical modules are developing towards 10 Gigabit and above, and at the same time, the size of equipment is developing towards miniaturization. High integration leads to high heat generation, which brings the challenge of overheating in the equipment operating environment. In the traditional solution, the heat sink of the device directly contacts the photoelectric conversion module, and the heat generated from the chip needs to pass through the optical module shell and the gap between the heat sink and the path from the chip to the heat sink. If you want to improve the heat transfer efficiency from the chip to the radiator...
