A kind of heat radiator with Graphene bed course
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.
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.
