In many industrial applications, heat must be
transferred in the form of either an energy input into the system or removal of
energy produced in the system. Impinging fluid jets have been widely used in
many industrial processes, such as paper drying, glass tempering, gas turbine
blade cooling, and electronic cooling. In this study, the literature on
impingement jet for finned heat sinks is investigated and the parameters
affecting heat transfer is determined. It has observed that especially heat
exchangers, nuclear reactors, computers and a lot of electronics cooling the
fins are used for heat transfer from the system. Particularly, the fins are commonly
use that increase convective heat transfer for the purpose of cool the
electronic devices. Heat sinks reduce junction temperature by increasing
surface area and turbulence for this reason increasing operation temperature. It
has concluded that heat transfer characteristics of impinging air jets vary
depending on many parameters such as nozzle geometry, velocity profile, nozzle
to surface distance, finned surface geometry, and temperature difference among
the jet, surface and ambient.
