HEAT PIPES, NANOFLUIDS, AND NANOTECHNOLOGIES

A survey of the constructions of heat pipes and thermosiphons with nanofl uids, nanocoatings, and nanocomposites based on metal oxides and carbon materials for volume absorption of solar energy and cooling of electronic components is presented. Nanofl uids are considered as actual working media intended for application in transparent heat miniexchangers, heat pipes, and thermosiphons for volume heating a nanofl uid by laser or solar radiation. Nanocoatings of the evaporator walls of heat pipes are created for intensifying two-phase heat transfer in cooling the devices of high-current electronics. Nanocomposites applied as heat pipe and thermosiphon casings possess thermophysical and mechanical properties that in a number of cases are best than those from metals.
