ABSTRACT:
A support system for a cooling fan for a heat exchanger. A suspension system supports an inner hub inside an outer support structure. The inner hub or ring supports the fan and motor. The suspension system includes an array of spiral support arms, extending from the inner hub to the outer supports. These arms have both spanwise and chordwise camber. The particular suspension system increases natural frequencies of the support system, over that wherein purely radial arms connect the inner hub and outer supports.
