Graphite film heat conductor

Abstract

The invention discloses a graphite film heat conductor which is made of a graphite film in a coiled mode. The graphite film heat conductor comprises a heat conducting component, a heat contacting component and a cold contacting component, wherein the heat conducting component is located in the middle, and the heat contacting component and the cold contacting component are located at two ends. The graphite film is coiled at least one circle to form the heat conducting component, and the heat contacting component and the cold contacting component are not coiled into circles. According to the graphite film heat conductor, heat is rapidly transferred from a heating device to a heat sink by means of high thermal conductivity of the graphite film and large contacting areas between the graphite film heat conductor, and the heating device and the heat sink. Therefore, a temperature gradient on a heat conduction path is reduced or eliminated, unbalanced-temperature hot spot regions inside equipment are eliminated, and whole reliability and long-time working capability of the device and the equipment are improved. The graphite film heat conductor is easy to machine, convenient to use, and free of limitation of installation positions, and provides powerful help for high-degree integration, and ultra-small and ultra-thin purposes of the equipment.

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...

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.
