Problems solved by technology

However, the service life of the heat pipe is limited. If the load of the heat pipe exceeds its working capacity, the medium inside will be completely vaporized, and its thermal conductivity will be greatly reduced, thus entering a vicious circle; in addition, changing the installation position of the heat pipe will also affect its performance. Thermal conductivity

Abstract

A graphite film heat conductor formed by rolling a graphite film. The graphite film heat conductor comprises: a medial heat conduction component (103), and a heat contact component (101) and a cold contact component (102) respectively at either end. The heat conduction component (103) is formed by rolling the graphite film at least one turn; the heat contact component (101) and the cold contact component (102) are not rolled. Given the high thermal conductivity of the graphite film, rolling same increases the heat-transfer surface thereof between a heat-radiating component and a heat sink, causing heat to be rapidly transferred from said heat-radiating component to the heat sink, thus reducing or eliminating a temperature gradient on the heat conduction path, eliminating temperature imbalances and hotspot regions in equipment, and improving the overall reliability and long-time working capability of components and equipment. The graphite film heat conductor is easy to manufacture, convenient to use, and free of limitations of installation positions, and helps make equipment highly integrated, ultra-small and ultra-thin.

Description

technical field [0001] The invention relates to heat conducting equipment, in particular to a graphite film heat conducting body. Background technique [0002] As a specialized discipline, thermal design mainly studies the transfer or retention of heat in equipment. In the heat transfer design, it is often necessary to choose the heat transfer medium reasonably, not only to consider the heat transfer efficiency and heat transfer capacity of the radiator, but also to optimize its shape design, outer surface area and other factors to improve the overall heat dissipation efficiency of the heat transfer system . [0003] At the same time, with the rapid development of science and technology, electronic and optoelectronic products are developing towards light, thin, short, small and high power. Such development will increase the heat generation density of electronic and optoelectronic products, resulting in an increase in power loss. Therefore, the demand for heat dissipation o...
