Description
Technical field
The utility model relates to graphite flake technical field, is specially a kind of electrically conductive graphite sheet.
Background technology
In recent years, along with the development of electronic technology, electronic product is constantly updated and is regenerated, the size of its work package is more and more less, speed and the efficiency of work are more and more higher, and its caloric value is also increasing, therefore not only requires it to be equipped with corresponding heat abstractor, also to guarantee that heat abstractor has stronger heat-sinking capability, to ensure the reliability of properties of product and to extend its useful life.
Graphite heat conducting heat sink material, because its distinctive low-density (with respect to metal species) and high heat conduction and heat radiation coefficient and low thermal resistance become hyundai electronics series products and solve the preferred material of heat conduction and heat radiation technology.Graphite heat radiation fin heat conduction equably along the horizontal, vertical directions, the laminar structured surface that can adapt to better any product, can effectively play from level, vertical direction the effect of heat conduction and heat radiation.Graphite generally divides native graphite and electrographite, and the thickness of native graphite is thicker, but heat conduction and heat radiation is poor, and the thinner thickness of electrographite, heat conduction and heat radiation is stronger, and both tend to be subject to certain limitation while all separately use.
