Background technology
In recent years, with the continuous development of electronic technology, electronic product is constantly updated and is regenerated, the size of its work package
Less and less, the speed and efficiency more and more higher of work, its caloric value are also increasing, therefore it is corresponding not require nothing more than its outfit
Heat abstractor, it is also to be ensured that heat abstractor has higher heat-sinking capability, to ensure the reliability of properties of product and extend which to make
Use the life-span.
Graphite as heat conduction and heat radiation material, because of its distinctive low-density（Relative to metal class）With high heat conduction and heat radiation coefficient and
Low thermal resistance becomes the preferred material that hyundai electronicses class product solves heat conduction and heat radiation technology.Graphite heat radiation fin not only can be led along level
Heat, can also vertically heat conduction, especially with laminar structured, not only can preferably make which be applied to any product
Surface, can also effectively play a part of heat conduction and heat radiation.But in traditional handicraft, if often through the letter of dried layer graphite heat radiation fin
The mode of single superposition is increasing its thickness, but the graphite heat radiation fin of multiple-layer stacked does not only have elasticity, does not have buffering
Effect, it is also possible to reduce its heat conduction and heat radiation performance because of the reason for multilamellar, does not reach effective heat conduction and heat radiation effect between mechanism member
Really, in practice it has proved that, the number of plies is more, and graphite heat radiation fin is thicker, and its heat conduction and heat radiation performance is poorer；So as to cause the thickness of graphite heat radiation fin
Spending has very big restriction, and the space that cannot be filled up between mechanism member；While using graphite heat radiation fin heat conduction and heat radiation, also
Need to make it have insulating properties, and the graphite heat radiation fin of multiple-layer stacked does not possess insulating properties, very big inconvenience is brought to enterprise.
