By combining nanofluids with thermally excited oscillating motion in an oscillating heat pipe (OHP), we developed an ultrahigh-performance cooling device, called the nanofluid oscillating heat pipe. Experimental results show that when the OHP is charged with nanofluid, heat transport capability significantly increases. For example, at the input power of 80.0 W, diamond nanofluid can reduce the temperature difference between the evaporator and the condenser from 40.9 to 24.3℃. This study will accelerate the development of a highly efficient cooling device for ultrahigh-heat-flux electronic systems.
