Heat Sink Definition in a cpu
Heat Sink Definition In a cpu is a device that allows the
lowering of the temperature of components that give off heat like the
transistor or processors, preventing overheating of the same cause it to
malfunction, shutdown or failure.
The materials used are copper and aluminum, the first is
used in cases where it should be the maximum efficiency in heat transfer,
accepting the higher cost and higher specific weight, aluminum is chosen for
less demanding operating conditions. Heat Sink Definition for All CPUs have them because of the heat
generated. It is usually shaped toroidal blades configured to increase the
efficiency in heat dissipation, is coupled to a fan powered by a small electric
motor (connected directly to the motherboard) that provides a flow of ventilation
air. There are many other forms, conformed according to the components that have
to pluged, in some cases, mainly bulky equipment evolving much heat, are part
of the carrier frame. When you need extreme performance and small footprint, we
adopt the solution called "ventilation", as in the case of CPU or
electronic instrumentation.
Particular attention should be paid to the coupling between
the mechanical device that generates heat and the heat sink, for maximum
efficiency, is interposed between two surfaces in contact, thermal paste, which
functions as a completely eliminate the veil of air inevitably present, being
the itself a poor thermal conductor, would limit the efficiency.
