Abstract

A fan assembly includes a fan module having a plurality of mounting openings, a housing partially surrounding the fan module, and a plurality of dampers that extend through the plurality of mounting openings to couple the fan module to the housing.

First claim

We claim:

1. A data storage system comprising:
a drawer;
a plurality of fan assemblies positioned within the drawer, each fan assembly comprising:
a fan module having a plurality of mounting openings,
a housing partially surrounding the fan module, and
a plurality of dampers that extend through the plurality of mounting openings to couple the fan module to the housing;

a fan cage assembly positioned within the drawer and including fan cages, each of the plurality of fan assemblies removably coupled to a respective fan cage; and
a circuit board positioned within the drawer, each of the fan cages including a plurality of legs extending from a bottom sidewall of the fan cages towards the circuit board to create a space between the bottom sidewall of the fan cage and the circuit board to permit electrical components to pass underneath the fan cage assembly.

2. The data storage system of claim 1 , wherein each of the fan cages includes a first opening and a second opening, and wherein the housing of the respective fan assemblies includes a first coupler and a second coupler positioned on opposite sides of the housing, and wherein the fan assemblies are removably coupled to the respective fan cages via engaging and disengaging the first coupler with the first opening and engaging and disengaging the second coupler with the second opening.

3. The data storage system of claim 2 , wherein the first couplers are positioned on respective first flexible portions, and wherein the second couplers are positioned on respective second flexible portions.

4. The data storage system of claim 1 , wherein the housings include a first handle coupled to a first flexible portion and a second handle coupled to a second flexible portion.

5. The data storage system of claim 1 , wherein the fan cage assembly includes.

6. The data storage system of claim 1 , wherein the housings include an electrical connector portion with an opening.

7. The data storage system of claim 1 , wherein the housings surround only four sides of the respective fan modules.

8. The data storage system of claim 1 , wherein the housings include a first finger guard and a second finger guard opposite the first finger guard.

9. An apparatus comprising:
a fan module having a plurality of mounting openings and electrically coupled to an electrical connector;
a housing partially surrounding the fan module, the housing including:
a first housing member having a first finger guard,
a second housing member coupled to the first housing member and having a second finger guard and an electrical connector portion, the electrical connector portion extending from the second housing member and including an opening shaped such that the electrical connector can be moved between a secured and a non-secured position within the opening, and
a plurality of openings, one of which includes a recessed portion;

a plurality of dampers that extend through the plurality of mounting openings to couple the fan module to the housing and that extend through respective openings of the plurality of the openings of the housing; and
an electrical wire electrically coupled between the electrical connector and the fan module and extending through the recessed portion.

10. The apparatus of claim 9 , wherein the dampers comprise an elastomer.

11. The apparatus of claim 9 , wherein the
housing surrounds only four sides of the fan module.

12. The apparatus of claim 9 , wherein the first housing member includes a first flex portion coupled to a first handle and a second flex portion coupled to a second handle.

13. The apparatus of claim 9 , wherein the second housing member includes a first opening and a second opening, wherein the first housing includes a first coupler and a second coupler, wherein the first coupler at least partially extends in the first opening, and wherein the second coupler at least partially extend in the second opening.
