Patent attributes
A heat transfer fluid comprising a carrier fluid and a nano-additive is provided. The heat transfer fluid is manufactured by dispersing the nano-additive in the carrier fluid. The nano-additive comprises nano-particles having a porous structure that provides dispersion stability of the nano-additive in the heat transfer fluid. The nano-additive structure has an aspect ratio of about 1.0 to about 10,000, a porosity of about 40% to about 85%, a density of about 0.4 g/cc to about 3.0 g/cc, an average pore diameter of about 0.1 nanometer to about 100 nanometers, and a specific surface area of about 1 m2/g to about 4000 m2/g. The nano-additive increases the heat transfer efficiency of the heat transfer fluid and also reduces the moisture content of the heat transfer fluid.
