Description

The three-dimensional heat-transfer device of macromolecule graphite

Technical field

The utility model relates to the 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 efficient 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, to guarantee that also heat abstractor has stronger heat-sinking capability, with the reliability that guarantees properties of product with prolong its useful life.

Graphite is as the 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 the hyundai electronics series products solves the 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 because the limit of traditional handicraft, the graphite heat radiation fin that native graphite makes heat conduction and heat radiation coefficient when multi-angle is crooked will descend, thereby reduced the heat conduction and heat radiation performance of graphite heat radiation fin, although and 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 just is limited on the plane-heat-transfer, and the heat that can't be applied in the stereoscopic three-dimensional space is conducted, and has greatly limited the range of application of graphite heat radiation fin.

The utility model content

According to an aspect of the present utility model, provide macromolecule graphite three-dimensional heat-transfer device, comprise fixture and graphite linings, the graphite linings bag is located at the outside of fixture and is shaped to one with fixture.Thus, can have 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 the graphite linings.Thus, can have the effect that increases the strong degree between graphite linings and the 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 have thus the effect that makes things convenient for fixture folding, also can reduce the production cost of the three-dimensional heat-transfer device of this macromolecule graphite simultaneously.

Description of drawings

Fig. 1 is the structural representation of the three-dimensional heat-transfer device of macromolecule graphite of the utility model one execution mode.

Embodiment

Below in conjunction with accompanying drawing utility model is described in further detail.

Fig. 1 has schematically shown according to the three-dimensional heat-transfer device of the macromolecule graphite of a kind of execution mode of the present utility model.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 at the outside of fixture 1 and are shaped to one with fixture 1.So just can realize increasing the effect of its heat conduction and heat radiation thickness.And be connected more firmly in order to make between graphite linings 2 and the fixture 1, so also comprise mucigel 3, mucigel 3 is located between fixture 1 and the 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 make this device that changes after the shape can realize heat conduction in the 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 need heat-dissipating thing in the trench structure be installed heat conduction and heat radiation by this, and 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 make things convenient for the folding of fixture 1, also can reduce the production cost of this device simultaneously.

Above-described only is execution modes more of the present utility model.For the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, can also be bent into circle, U-shaped, stairstepping, triangle, the shape such as square such as fixture 1, these all belong to the protection range of utility model.
