Researchers at Sweden's Institute of Technology have discovered new nanofluids that can improve the efficiency of cooling systems for server farms. The scientists found that adding some nanoparticles to cooling fluids can improve the ability to conduct heat by as much as 60 percent. So far oxides of metals like zinc and copper show the most potential, but carbon nanotubes are also being tested. The technology shows great potential to cut energy consumption and save businesses lots of money.
"What we are using are nanofluids, which are fluids engineered to contain nanoparticles dispersed in such a way that the liquid's capability to move heat is much enhanced compared to normal cooling fluids," said Muhammed.
"For example, if you are using water to cool electronic equipment [such as at large server farms] and you add these nanoparticles, and create a nanofluid, it improves the water's capability to conduct heat by 30 to 40 percent."
