Abstract
The invention discloses a graphite heat conducting foam. The graphite heat conducting foam comprises a graphite layer and a foam layer, wherein the graphite layer is arranged at the exterior of the foam layer, and the graphite layer and the foam layer are molded to form one entity. According to the graphite heat conducting foam of the invention, since the graphite layer covers the foam layer, the thickness of a graphite radiating sheet can be visually increased, and at the same time, the heat conduction and dissipation performance of the graphite radiating sheet is enhanced, the elastic effect of the foam layer also can be realized on the graphite radiating sheet, and the buffer property of the graphite radiating sheet is improved.
Description
Technical field
The present invention relates to heat-transfer device, particularly utilize graphite to realize the graphite heat conducting foam of heat conduction and heat radiation.
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 in traditional handicraft, often the mode by some layers of graphite heat radiation fin simple superposition increases its thickness, yet the graphite heat radiation fin of multiple-layer stacked does not only have elasticity, do not have the effect of buffering, also may thereby reduce its heat conduction and heat radiation performance because of the former of multilayer, do not reach effective heat conduction and heat radiation effect between mechanism's part, facts have proved, the number of plies is more, and graphite heat radiation fin is thicker, and its heat conduction and heat radiation performance is poorer; Thereby the thickness that causes graphite heat radiation fin has had very large restriction, and the space ，Gei enterprise that cannot fill up between mechanism's part brings very large inconvenience.
Summary of the invention
According to an aspect of the present invention, provide graphite heat conducting foam, comprised graphite linings and foamed cotton layer, wherein graphite linings is located at foamed cotton layer outside and is shaped to one with foamed cotton layer.Thus, can there is the effect that increases elasticity, fills up the space between mechanism's part.
In some embodiments, wherein, be also provided with mucigel between graphite linings and foamed cotton layer, mucigel is in aggregates by graphite linings and foamed cotton layer adhesion.Thus, can have and make the more firm effect of whole graphite heat conducting foam.
In some embodiments, wherein, foamed cotton layer is cube structure, and graphite linings bag is located at the above and below of foamed cotton layer and is gone up above, and the graphite linings of three faces is around forming U-shaped structure.Thus, can there is the effect that facilitates heat conduction and heat radiation between mechanism's part.
In some embodiments, wherein, foamed cotton layer is cube structure, and graphite linings bag is located at forward and backward and above and below of foamed cotton layer, and the graphite linings of four faces is around forming square shape pipe structure.Thus, can there is the more obvious effect of the heat conduction and heat radiation of making performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the graphite heat conducting foam of an embodiment of the present invention;
Fig. 2 is the structural representation of the graphite heat conducting foam of another execution mode of the present invention.
Embodiment
Below in conjunction with accompanying drawing, invention is described in further detail.
Fig. 1 has schematically shown the graphite heat conducting foam according to one embodiment of the present invention.As shown in the figure, this graphite heat conducting foam comprises graphite linings 1 and foamed cotton layer 2, in order to have heat conduction and heat radiation performance, so graphite linings 1 is located at the outside of foamed cotton layer 2 and is shaped to one with foamed cotton layer 2.So not only can make this graphite heat conducting foam there is heat conduction and heat radiation, can also there is the effect that increases elasticity, fills up the space between mechanism's part.And more firm in order to make between graphite linings 1 and foamed cotton layer 2, so be also provided with mucigel 3 between graphite linings 1 and foamed cotton layer 2, mucigel 3 is in aggregates by graphite linings 1 and foamed cotton layer 2 adhesions.So just can reach the more firm effect of whole graphite heat conducting foam.In order to improve heat conductivility, so foamed cotton layer 2 is cube structure, graphite linings 1 bag is located on the above and below of foamed cotton layer 2 and surface above.Now the graphite linings 1 of three faces is around forming U-shaped structure.So just can reach the effect that facilitates heat conduction and heat radiation between mechanism's part.
Referring to Fig. 2, another specific embodiment of the present invention, be with the difference of a upper embodiment, owing to needing in using, the space environment of heat conduction and heat radiation is different, so foamed cotton layer 2 is cube structure, graphite linings 1 bag is located at forward and backward and above and below of foamed cotton layer 2, and the graphite linings 1 of four faces is around forming square shape pipe structure.When this graphite heat conducting foam is folded between mechanism's part in the process of using, owing to being provided with foamed cotton layer 2 in the middle of this graphite heat conducting foam, so when needing mechanism's part of heat conduction and heat radiation to push mutually, can play certain cushioning effect because foamed cotton layer 2 has elasticity.Can not affect graphite heat conducting foam heat conduction and heat radiation performance in use.
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, these all belong to the protection range of invention.
