Description

Graphene radiator

Technical Field

The utility model relates to the field of radiators, in particular to a graphene radiator.

Background

With the development of the era, the demand of servers for data computation has increased, and thus, the power of a high-performance Central Processing Unit (CPU) required by the servers has also increased gradually, for example, for use in the current large-sized workstations, small-sized and medium-sized commercial servers, and other Personal Computer (PC) products. As the power consumption of the server increases, the operating temperature of the associated electronics is at a serious risk of overtemperature. Therefore, to maintain the service life and reliability of the server and to improve the working efficiency of the server, the heat dissipation problem of the server is solved.

The traditional large-scale work station and the medium-sized and small-sized commercial servers generally adopt heat pipe and air cooling heat dissipation modes, and the heat dissipation modes have the advantages of large occupied space, high commercial cost, larger noise, and shorter service life. Particularly, the heat dissipation mode of the heat pipe is adopted, and the heat pipe cannot be deformed and can only have a certain shape, so that the space is greatly limited, and the heat pipe cannot be distributed in some complex spaces, so that effective heat dissipation cannot be realized. The air cooling heat dissipation effect is more general, and dust accumulation is easy to occur in the air cooling heat dissipation.

The Vapor Chamber (VC) is also called a vapor chamber, and has a micro-structure on the inner wall, so that the vapor chamber has the advantage of rapid heat conduction, and can transfer heat from a hot spot to the whole surface for heat dissipation. The graphene sheet has super-strong thermal conductivity and lower thermal resistance, and has extremely high flexibility and is easy to shear. Typically, the thermal conductivity of a graphene sheet can reach 600-1200W/(mk), which is 2-4 times that of copper, but the thermal power of a single graphene sheet is relatively low.
