Description

A kind of heat radiator with Graphene bed course
Technical field
The utility model relates to computer to dissipate heat technical field, is specially a kind of heat radiator that can be used for the band Graphene bed course of notebook computer north and south bridge heat radiation.
Background technology
Computer equipment is due to the demand of function and processing speed; the heat of high temperature produced during the work of its inner member is quite large; and these heat of high temperature cannot shed and easily cause related elements because autoprotection and forced shutdown is restarted in the small space of computer casing; affect normal use and the serviceable life of equipment, this point shows particularly evident on notebook computer.
And in notebook computer, main heater element mainly concentrates on north and south bridge portion, for elements such as CPU, GPU, its integrated level and frequency of operation higher, also higher to the requirement of heat radiator, heat abstractor in existing notebook computer is formed primarily of fan and some heat radiator, wherein, the heat produced when heat radiator is for absorbing the work of computer equipment inner member, heat abstractor needs to distribute heat in surrounding enviroment as early as possible to go after absorbing heat, thus requires higher to the heat exchange performance of heat radiator.In prior art, the heat radiation of high-power south, north bridge heater element is improved usually to the radiating effect of heating radiator by the number of the heat radiator increasing computer radiator, and the inner space of notebook computer is limited, easily like this have influence on the integrally-built integrated of notebook.
Utility model content
The technical matters that the utility model solves is to provide a kind of heat radiator with Graphene bed course, to solve the shortcoming in above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of heat radiator with Graphene bed course, comprise the substrate that is fixed on south, north bridge frame and be molded over on-chip cooling stand, the square section of described cooling stand is I shape, it is evenly provided with some radiating ribs, and described substrate is three-layer composite structure, be followed successively by the base copper of fitting with north and south bridge, the X alloy layer being molded over the Graphene rete on base copper and being molded on Graphene rete, and form one deck heat dissipating silicone grease or tin cream between Graphene rete and X alloy layer.
In the utility model, described cooling stand and substrate are threaded connection part at the corner location of substrate and are connected, and scribble one deck heat dissipating silicone grease or tin cream on the joint face of cooling stand and substrate.
In the utility model, the X alloy layer upper surface of described substrate forms some concentric annular burrs, this burr tangent plane is triangle or trapezoidal.
In the utility model, the thickness of described base copper is 8 ~ 15mm, and the thickness of X alloy layer is 5 ~ 8mm.
In the utility model, described radiating ribs is sheet or strip.
In the utility model, described cooling stand has in advance radiator fan and threaded hole is installed.
Beneficial effect: the utility model utilizes radiating ribs to increase the area of dissipation of heat radiator, improve the radiating effect of computer radiator, simultaneously, utilize Graphene rete as heat-conducting medium, coordinate the different Heat Conduction Material in both sides can effective notebook internal heat energy is derived while the size of heat radiator is controlled in a rational scope, carry out inner space with computer equipment be equipped with to facilitate, and the radiator fan installation threaded hole be arranged on cooling stand can dispel the temperature on heat radiator fast by fan, realize the double-radiation function function to notebook.
