Providing adequate cooling
The enclosure design must ensure adequate cooling for
the drive. The maximum ambient temperature is 45
o
C.
The drive’s product manual (83328860) describes how
to evaluate the air-flow design. The evaluation consists
of ensuring that the case temperature of certain critical
components remains 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 10 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.
