Abstract: 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.

Abstract: Disclosed herein is a method and system for transporting heat from a heat source to a heat sink. Containers containing a phase change material in a first phase, a guide track leading from the heat source to the heat sink, and a drive system are provided. The phase change material in the first phase in the containers absorbs the heat from the heat source on establishing thermal contact with the heat source and changes to a second phase. The drive system moves the containers containing the phase change material in the second phase to the heat sink along the guide track. The phase change material in the second phase in each of the containers transfers the absorbed heat to the heat sink and changes to the first phase. The heat source is cooled due to transportation of the heat from the heat source to the heat sink.
