Fan Isolation Mount
Disclosed is a system for mounting cooling fans, requiring isolation for
acoustic qualities in electrical packages containing heat producing components.
This method of fan mounting is simply to attach a rectangular piece of
adhesive-backed foam to the outside perimeter of the fan and insert the fan into
a receiving pocket. The foam is compressed, providing the required friction for
fan retention (see figure).
The thickness and width of the foam is dimensionally controlled as well as the
receiving pocket design to establish an operating span which allows the fan to
function while eliminating unwanted vibrations.
This approach is quick, inexpensive and meets the isolation requirements. It
is achieved by simply inserting the fan in the pocket with no adjustments or
special assembly instructions.
