Abstract

In various implementations, a fan system may include a housing and a fan. The fan may reside in an orifice of the housing. The fan system may include a grate disposed proximate a top surface and an ice deflector. The ice deflector may inhibit ice formation on portions of the housing, orifice, and/or fan residing in the orifice.

First claim

The invention claimed is:

1. A method comprising:
disposing an ice deflector proximate a grate of a fan system such that the grate is disposed between the ice deflector and an orifice of the fan system, and wherein the ice deflector comprises:
a base having one or more sloped portions;
an annular protrusion; and
an opening formed by the annular protrusion;

aligning the opening formed by the annular protrusion with an orifice of the fan system;
coupling the ice deflector to the grate with a first plurality of coupling members; and
coupling at least a portion of the ice deflector and at least a portion of a housing of the fan system with a second plurality of coupling members;
wherein the ice deflector is configured to direct precipitation away from a surface of the fan system.

2. The method of claim 1 , wherein coupling at least a portion of the ice deflector and at least a portion of the of the housing of the fan system comprises allowing an exterior surface of a housing of the fan system to be frictionally fit between protrusions of the ice deflector, wherein the protrusions of the ice deflector extend from the base of the ice deflector.

3. The method of claim 1 , wherein coupling at least a portion of the ice deflector and at least a portion of the housing of the fan system comprises disposing an exterior surface of a housing of the fan system between protrusions of the ice deflector, wherein the protrusions of the ice deflector extend from the base of the ice deflector.

4. A method of claim 1 , further comprising removing the ice deflector from the fan system by uncoupling at least a portion of the ice deflector from at least a portion of the fan system.

5. The method of claim 1 , further comprising allowing access to a fan of the fan system, wherein allowing access comprises:
uncoupling the ice deflector and the fan system;
removing the ice deflector from the fan system; and
removing the grate from the fan system.

6. The method of claim 1 , further comprising inhibiting ice accumulation on a flange of the fan system.

7. The method of claim 1 , further comprising inhibiting ice bridge formation in the fan system.

8. An ice deflector for a fan system comprising:
a base;
an annular protrusion coupled to the base;
an opening formed by the annular protrusion;
a first plurality of coupling members operable to couple the ice deflector to a grate disposed between the ice deflector and a housing of the fan system; and
a second plurality of coupling members operable to couple the ice deflector to the housing of the fan system;
wherein the ice deflector is adapted to be coupled to a fan system and wherein the ice deflector is adapted to inhibit ice formation in at least a portion of the fan system when the ice deflector is coupled to the fan system.

9. The ice deflector of claim 8 , wherein the base comprises:
a base width greater than or equal to a width of a housing of the fan system; and
a base length greater than or equal to a length of the housing of the fan system.

10. The ice deflector of claim 8 , wherein the base is adapted to cover at least a portion of a flange of the fan system.

11. The ice deflector of claim 8 , wherein the opening of the ice deflector comprises:
an opening length less than an orifice length of the fan system; and
an opening width less than an orifice width of the fan system.
