Abstract

Computer systems increasingly present the problem of removal of heat, while at the same time providing decreasing amounts of space for mounting the necessary ventilation fan. Also, as systems become more compact, the risk that the moving parts of the fan come into contact with cables and the components is increased, requiring means for guarding such parts.

Ventilation Fan Mounting

      Computer systems increasingly present the problem of removal
of heat, while at the same time providing decreasing amounts of space
for mounting the necessary ventilation fan.  Also, as systems become
more compact, the risk that the moving parts of the fan come into
contact with cables and the components is increased, requiring means
for guarding such parts.

      By using a special bracket, preferably incorporating an
integral fan guard as described here, a conventional fan may be
mounted in a confined space while still permitting maximum airflow
for ventilation.

      Referring to Fig. 1, the bracket 1 includes a clip portion 2
and a guard portion 3.  The clip portion carries two location tabs 4
and the guard portion carries four crimp tabs 5, disposed to register
with the mounting holes of the ventilation fan.

      The fan 6 is mounted, as shown in Fig. 2, by inserting it into
the bracket with the four crimp tabs 5 entering mounting holes 7.
The crimp tabs are bent inwards to secure the fan to the bracket
while the  two location tabs 4 locate the fan accurately on the
bracket.

      The clip portion 2 of the bracket 1 is preferably dimensioned
to clip on to a major fixed component of the computer, such as the
power supply, thus avoiding the use of screws in the assembly.
