Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

CLAIMS

1. A fan module for a cooling unit, the fan module comprising:

a housing configured to be secured within the cooling unit, the housing having a first open end and a second open end spaced from the first open end;

a fan assembly secured within the housing at the first open end of the housing, the fan assembly including a fan support, a fan rotatably coupled to the fan support, and a motor coupled to the fan to drive rotation of the fan, the fan support being configured to support the fan assembly within the housing; and

a noise reduction assembly disposed in the housing adjacent the fan assembly to reduce noise generated by the fan assembly.

2. The fan module of claim 1, wherein the noise reduction assembly includes a holder configured to be secured to one of the fan support and the housing, and an acoustic component secured to the holder.

3. The fan module of claim 2, wherein the acoustic component includes a foam cylinder that extends from the holder towards the second open end of the housing.

4. The fan module of claim 3, wherein the foam cylinder is centrally positioned within the housing so that it is coaxial with the fan of the fan assembly.

5. The fan module of claim 4, further comprising a foam liner secured to an interior surface of the housing.

6. The fan module of claim 2, wherein the holder includes a plate and rod extending from the plate, the rod being configured to support the acoustic component.

7. The fan module of claim 1, further comprising a first guard secured to the first end of the housing to prevent access to the fan assembly.

8. The fan module of claim 7, further comprising a second guard secured to the second end of the housing.

9. The fan module of claim 8, further comprising a duct cover secured to the second end of the housing inboard from the second guard.

10. A method of cooling comprising:

disposing a fan module within a cooling unit, the fan module being configured to draw air into the cooling unit; and

moving air over a noise reduction assembly disposed in a housing of the fan module to reduce noise generated by the fan assembly.

11. The method of claim 10, wherein the noise reduction assembly includes a holder configured to be secured to one of a fan support and a housing of the fan module, and an acoustic component secured to the holder.

12. The method of claim 11, wherein the acoustic component includes a foam cylinder that extends from the holder towards the second open end of the housing.

13. The method of claim 12, wherein the foam cylinder is centrally positioned within the housing so that it is coaxial with the fan of the fan assembly.

14. The method of claim 11, wherein the housing includes a foam liner secured to an interior surface of the housing.

15. A cooling unit comprising:

a housing;

a heat exchanger supported by the housing; and

a plurality of fan modules supported by the housing and configured to draw air into the housing and through the heat exchanger, each fan module comprising

a housing configured to be secured within the cooling unit, the housing having a first open end and a second open end spaced from the first open end,

a fan assembly secured within the housing at the first open end of the housing, the fan assembly including a fan support, a fan rotatably coupled to the fan support, and a motor coupled to the fan to drive rotation of the fan, the fan support being to support the fan assembly within the housing, and

a noise reduction assembly disposed in the housing adjacent the fan assembly to reduce noise generated by the fan assembly.

16. The cooling unit of claim 15, wherein the noise reduction assembly includes a holder configured to be secured to one of the fan support and the housing, and an acoustic component secured to the holder.

17. The cooling unit of claim 16, wherein the acoustic component includes a foam cylinder that extends from the holder towards the second open end of the housing.

18. The cooling unit of claim 17, wherein the foam cylinder is centrally positioned within the housing so that it is coaxial with the fan of the fan assembly.

19. The cooling unit of claim 18, wherein the fan module further includes a foam liner secured to an interior surface of the housing.

20. The cooling unit of claim 16, wherein the holder includes a plate and rod extending from the plate, the rod being configured to support the acoustic component.
