Providing adequate cooling
The enclosure design must ensure adequate cooling for
the drive. The maximum ambient temperature is 50
o
C.
The drive’s product manual (83328930) describes how
to evaluate the air-flow design. The evaluation consists
of ensuring that the case temperatures of certain critical
components remain within acceptable limits during drive
operation.
We recommend orienting the drive or directing the air
flow in a way that creates the least amount of air-flow
resistance while providing air flow above the circuit
boards and around the head and disc assembly (HDA).
Also, choose the shortest possible path between the air
inlet and exit. This minimizes the distance traveled by air
that is heated by the drive and by other nearby heat
sources.
Figure 3 shows two design approaches with one or more
fans used to generate air flow. The air-flow patterns can
be created by the fans either pushing or drawing air. The
overall flow pattern can be directed from front to back,
back to front, or side to side.
