Abstract
The invention discloses a polymer graphite three-dimensional heat conduction device. The device comprises a fixing piece and a graphite layer, wherein the graphite layer is arranged at the exterior of the fixing piece, and the graphite layer and the fixing piece are molded so as to form one entity. The polymer graphite three-dimensional heat conduction device of the invention is advantageous in increased thickness of heat conduction and heat radiation and realization of three-dimensional heat conduction.
Description
Technical field
The present invention relates to graphite heat conducting device, particularly the three-dimensional heat-transfer device of macromolecule graphite.
Background technology
In recent years, development along with 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 require it to be equipped with corresponding heat abstractor, also to guarantee that heat abstractor has stronger heat-sinking capability, to guarantee the reliability of properties of product and to extend its useful life.
Graphite is as heat conduction and heat radiation material, because its distinctive low-density (with respect to metal species) and high heat conduction and heat radiation coefficient and low thermal resistance become the preferred material that hyundai electronics series products solves heat conduction and heat radiation technology.Graphite heat radiation fin not only can be along horizontal heat conduction, and vertically heat conduction is especially used laminar structuredly, not only can make better its surface that is applicable to any product, also can effectively play the effect of heat conduction and heat radiation.But the limit due to traditional handicraft, the graphite heat radiation fin that native graphite makes heat conduction and heat radiation coefficient when multi-angle is crooked will decline, thereby reduced the heat conduction and heat radiation performance of graphite heat radiation fin, and although the impact when multi-angle is crooked of its heat conduction and heat radiation coefficient of the graphite heat radiation fin that synthetic graphite makes is little, but its production cost is higher, therefore the application of the heat conduction and heat radiation performance of above-mentioned two kinds of graphite heat radiation fins is just limited on plane-heat-transfer, and the heat that cannot be applied in stereoscopic three-dimensional space is conducted, greatly limited the range of application of graphite heat radiation fin.
Summary of the invention
According to an aspect of the present invention, provide macromolecule graphite three-dimensional heat-transfer device, comprised fixture and graphite linings, graphite linings bag is located at the outside of fixture and is shaped to one with fixture.Thus, can there is the effect that increases the three-dimensional heat-transfer device heat conduction and heat radiation of this macromolecule graphite thickness.
In some embodiments, also comprise mucigel, mucigel is located between fixture and graphite linings.Thus, can there is the effect that increases the strong degree between graphite linings and fixture.
In some embodiments, fixture is folding fixture.Thus, can have and utilize folding fixture to make graphite linings realize bending, and not affect the effect of the heat conduction and heat radiation coefficient of graphite linings when bending.
In some embodiments, fixture is comprised of iron or plastic cement.Can there is the effect that facilitates fixture folding thus, also can reduce the production cost of the three-dimensional heat-transfer device of this macromolecule graphite simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the three-dimensional heat-transfer device of macromolecule graphite of an embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, invention is described in further detail.
Fig. 1 has schematically shown according to the three-dimensional heat-transfer device of the macromolecule graphite of one embodiment of the present invention.As shown in the figure, this device comprises fixture 1 and graphite linings 2, in order to increase the thickness of this heat-transfer device heat conduction and heat radiation, therefore graphite linings 2 bags are located to the outside of fixture 1 and are shaped to one with fixture 1.So just can realize the effect that increases its heat conduction and heat radiation thickness.And between graphite linings 2 and fixture 1, be connected more firmly in order to make, so also comprise mucigel 3, mucigel 3 is located between fixture 1 and graphite linings 2, utilizes mucigel 3 that graphite linings 2 and fixture 1 are bonded together.Can make this device more firm, be not easy destroyedly, but also can when changing shape, be not easy breakage, and not affect its heat conduction and heat radiation effect.Because need to make the change shape that this device can be random, and this device that makes to change after shape can realize the heat conduction in three dimensions, so fixture 1 is folding fixture 1.The present embodiment fixture 1 has been bent into trench structure, so just can make the heat-dissipating thing that needs in trench structure be installed heat conduction and heat radiation by this, and does not affect the heat conduction and heat radiation coefficient of graphite linings 2 when bending, reaches good heat conduction and heat radiation effect.And in order conveniently to reach the effect of bending, so fixture 1 is comprised of iron or plastic cement, so just can facilitate the folding of fixture 1, also can reduce the production cost of this device simultaneously.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art; without departing from the concept of the premise of the invention; can also make some distortion and improvement, as fixture 1 can also be bent into circle, U-shaped, stairstepping, triangle, the shape such as square, these all belong to the protection range of invention.
