abstract = "The subject of this article is related to the development of a
thermal management solution for a surveillance equipment, which
needs to dissipate high levels of heat loads using both active and
passive thermal control devices. A thermal management system was
designed to use both a singlephase forced circulation loop and
heat pipes using copper oxide (CuO)-water nanofluid, designed to
promote the thermal management of up to 50 kW of heat generated by
several arrays of electronic components, being dissipated to the
environment by a fan cooling system. The heat pipes collect the
heat from electronic components that are far from the main
single-phase forced circulation loop, rejecting the heat directly
in its cold plates. Results show that with an addition of 20% by
mass of CuO nanoparticles to the base fluid in the single-phase
system, enhancements of 12% in the heat transfer coefficients were
achieved but the increase in the pressure drop was around 32%. The
use of nanofluid in the heat pipes resulted in a substantial
decrease in the heat source temperature. Upon using nanofluids in
heat pipes, the maturity of this technology is considerably
high.",
