14 DAY TRIAL // Though discovered only about 7 years ago, graphene is already being touted as the most significant material to be discovered over the last century. In a new study, experts have shown that it can be used to cool electronics that can produce a lot of heat, with great efficiency.
By creating a copper-graphene composite, experts at North Carolina State University (NCSU) were able to show that lasers and other power devices can be cooled extremely well using this passive approach. The composite material does not need energy to work.
By turning the cooling down of electronics from an active to a passive process, the team may have just helped reduce the world's energy usage by a significant margin. Currently, computers feature 2 to 6 coolers on average, which are used to remove excess heat.
By connecting the copper-graphene composite to hot electronics using an indium-graphene interface film, the issue of heat dispersal could be resolved once and for all, Science Blog reports.
