Graphene radiator: thermal management options from car to tablet

     With the advent of self-driving cars, more computer computing power will be used, consoles, in-vehicle Internet, wireless networks and sensor arrays, which will consume more CPU power, and the superposition of various new applications will increase accordingly. Heat. The application of new graphene films in automobiles is bound to continue to expand. 

     Therefore, the demand for heat dissipation has increased accordingly. The use of traditional aluminum heat sinks will enlarge the size of consoles and other related computer/electronic systems, and the planar heat dissipation management solution using new graphene film heat sinks is not only thinner, but also more effective in heat dissipation.         For most PCBs, higher signal frequencies are already common, so the heat generated inside the PCB will be greater, causing the problem of planar thermal management to become more and more important. Engineers have been trying to solve thermal management problems with various types of thermal pastes, thermal substrates, and different forms of heat sinks (such as aluminum, copper, etc.); at the same time, the electronics industry is still seeking to take up less space, be more effective and more efficient. Economical solution          

     Graphene is an allotrope of carbon (carbon). It is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms and sp² hybrid orbitals. It is the basic structural element of many other forms of carbon, such as graphite, diamond, charcoal, carbon nanotubes and fullerenes. The thickness of graphene is thinner than one millionth of a piece of paper; because it is so thin, it can be considered a two-dimensional structure. Graphene's flat honeycomb pattern gives it many unusual characteristics, including being the strongest material in the world. Its strength comes from the uninterrupted hexagonal structure and strong bonds between carbon atoms. This strong bond has great toughness and can be twisted, stretched, and bent to a certain extent without breaking, which means that graphene is bendable and stretchable.

     The revolutionary material properties of graphene include:            

     The strongest material ever;             

     The thinnest material known in science;             

     High toughness and excellent light transmittance;             

     The most impermeable material on earth;             

     Record thermal and electrical conductivity;             

     And incredibly energy-efficient.
