Abstract
The utility model provides a compound radiating wing, include middle graphite lamella and lie in the metal lamella on graphite layer two sides, because the graphite lamella has excellent heat conductivility, can arrive heat transfer rapidly on the metal lamella, and the metal lamella has effects such as the thermal current is big, can be with heat fast transferring to the environment in.
Description
Technical field
The utility model relates to radiating element field, refers to a kind of composite radiating wing especially.
Background technology
Along with electronic equipment performance improves constantly, processing speed is faster, process frequency is higher, volume is less, weight is lighter, power is higher, and the heat that electronic devices and components produce is also more and more higher, and this cooling system to electronic devices and components proposes stricter requirement.The radiating wing that radiator in present cooling system uses is aluminium flake, although hot-fluid is large, heat conductivility is poor, more and more can not meet the cooling requirements of electronic devices and components.Therefore need to invent the large and radiating wing of good heat conductivity of a kind of hot-fluid.
Utility model content
The utility model proposes a kind of composite radiating wing, solve cooling electronic component in prior art difficult, the problem of heat conductivility difference.
The technical solution of the utility model is achieved in that a kind of composite radiating wing, comprise middle graphite flake layer and the metal plate layer being positioned at described graphite linings two sides, because described graphite flake layer has excellent heat conductivility, can rapidly heat be delivered on described metal plate layer, and described metal plate layer has the effects such as hot-fluid is large, heat can be delivered in environment fast.
Preferably, described metal plate layer is aluminium foil layer, and aluminium foil has good heat-conducting effect and hot-fluid is large.
Preferably, described metal plate layer can be also copper foil layer, and Copper Foil also has good heat-conducting effect and hot-fluid is large.
Preferably, described graphite flake layer is Graphene heat conducting film, and Graphene heat conducting film has excellent heat conductivility.
Preferably, described graphite flake layer also can adopt graphite flake, and the heat conductivility of graphite flake is also very good.
Further, the edge of described metal plate layer is welded as entirety, and it is inner that described graphite flake layer is positioned at described metal plate layer, thus realizes the good protection to described graphite flake layer.
Further, described metal plate layer is provided with several impulse welding contacts, realizes better fixing.
The described composite radiating wing of the present utility model, has rapidly core space to be passed to described metal plate layer heat by described graphite flake layer, then has described metal plate layer to be delivered in environment, good heat conductivity, and rapid heat dissipation, can greatly meet the requirement of electronic devices and components.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

As depicted in figs. 1 and 2, a kind of composite radiating wing, comprise middle graphite flake layer 1 and the metal plate layer 2 being positioned at graphite linings 1 two sides, because graphite flake layer 1 has excellent heat conductivility, can rapidly heat be delivered on metal plate layer 2, and metal plate layer 2 has the effects such as hot-fluid is large, heat can be delivered in environment fast.
Preferably, metal plate layer 2 is aluminium foil layer 2, and aluminium foil has good heat-conducting effect and hot-fluid is large.
Preferably, metal plate layer 2 can be also copper foil layer 2, and Copper Foil also has good heat-conducting effect and hot-fluid is large.
Preferably, graphite flake layer 1 is Graphene heat conducting film 1, and Graphene heat conducting film has excellent heat conductivility.
Preferably, graphite flake layer 1 also can adopt graphite flake 1, and the heat conductivility of graphite flake is also very good.
Further, the edge of metal plate layer 2 is welded as entirety, and it is inner that graphite flake layer 1 is positioned at metal plate layer 2, thus realizes the good protection to graphite flake layer 1.
Further, on metal plate layer, 2 are provided with several impulse welding contacts 3, realize better fixing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
