Nano suspension is uniform,stable and high thermal conductivity heat transfer medium, prepared by dispersing nano-particles in water,alcohol,oil and other tradition heat transfer medium.It is known to all,solid material's thermal conductivity coefficient is higher than liquid,and thus dispersing solid particles into liquid can enhance the thermal conductivity of the liquid.Nano suspension overcomes the flaws of common particle suspension.Due to Brown-movement,the particle can stay stability in suspe...
