Abstract

The present invention relates to a shock-absorbent structure of serially-connected fans. The serially-connected fans at least include two fan frames. A shock-absorbent element is disposed between the bonded surfaces of the fan frames and is made of a flexible material being shock-absorbent and damping. Therefore, when the fan rotor inside the fan frame rotates, the fundamental frequencies of two fan rotors are damped, and absorbed by the shock-absorbent element, thereby preventing the interaction of the fundamental frequencies from generating severe resonant effect and noise out of vibration and maintaining the optimized efficacy and the life span of the system.

Claims4

Dependent claims

A shock-absorbent structure of serially-connected fans, comprising;

at least two serially-connected fans having a respective fan frame, wherein said fan frame has a containing space therein for accommodating a fan rotor, a base is disposed at one end of said containing space, said base is integrally combined with said fan frame by means of a plurality of ribs, and said base is provided for mounting a driving device to drive said fan rotor to rotate;
and
a shock-absorbent element is disposed between two bonded surfaces of two of said fan frames, and said shock-absorbent element is made of a flexible material being shock-absorbent and damping wherein a form of said shock-absorbent material corresponds to and is not greater than that of said base, and a shallow recess is provided on an external end surface for accommodating said shock-absorbent element.

Dependencies are inferred from the claim text.
