Flat Cable Folding to Maximize Airflow

      A simple method to fold flat cables in an enclosure to maximize
airflow is disclosed.

      This disclosure describes a method to fold flat cables (as used
in a Direct Access Storage Device (DASD) enclosure) to maximize the
airflow through the enclosure.  Even though the figures show a
typical DASD subsystem, any cable could be folded in this manner to
accomplish better airflow through the enclosure.

      Fig. 1 shows a typical cable assembly to connect a controller
to a disk drive (DASD).  The view is from the top of the enclosure.
Flat cables which connect the controller (in the "Y" direction), to
the DASD connectors (in the "X" direction), block airflow in the "Z"
direction (i.e., out of the paper).

      By folding the cable in half lengthwise, then at a 45º
angle at the ends, maximum airflow in the "Z" direction is achieved:
this gives much better cooling for the controller card and the DASD
drives, while minimizing cable height in the Z direction.  The fold
is very inexpensive to manufacture and the cables are easy to install
(Figs. 2, 3, 4, and 5).
