Externally mounted on-line replaceable fan module
First Claim
1. An electrical component comprising,an exterior fan-mounting surface having airflow apertures and at least two electrical power supply connectors, and a cooling fan assembly having at least two fan units, each fan unit comprising a housing, an electric fan defining an outer diameter of fan blade rotation, a mount for selectively and releasably mounting the fan unit to the exterior fan-mounting surface, the mount being disposed on a region of said fan unit that is outside of the outer diameter of fan blade rotation, and an electrical connector releasably mateable with one of the at least two electrical power supply connectors of said exterior fan mounting surface, whereby one of said at least two fan units is individually removable from said exterior fan mounting surface without interrupting the operation of the other of said at least two fan units.

Abstract
A cooling fan apparatus includes a plastic housing and an electric fan. The housing containing the fan is mounted directly on the external surface of equipment being cooled. No separate mounting frame is utilized. The modular fan apparatus is on-line replaceable and is useful with other units to provide cooling fan redundancy. Preferably, a filtered electrical connector and a light emitting diode are integrated with the housing.

5. An electrical component comprising;
-
a planar externally facing fan mounting surface having a plurality of air flow apertures, a plurality of electrical power supply connectors connected in parallel and a plurality of fan unit receptacles defining an array of fan unit receiving sections, each fan unit receiving section having one electrical power supply connector and at least one fan unit receptacle, an array of fan units for mounting to the array of fan unit receiving sections, each fan unit having an electric fan including fan blades rotating in a path defining an outer path diameter, a box-shaped housing presenting a square-shaped open face and having spaced, opposed walls with openings to permit fan induced airflow through said housing, the housing presenting corner regions at a position outside of the outer path diameter of the fan blade path, and a mount for releasably fastening each fan unit to the fan unit receiving section of the fan mounting surface, whereby each fan unit of the array of fan units is individually removable from said fan mounting surface without interrupting the operation of the other fan units of said array of fan units.
