Abstract

An acoustical baffle includes a baffle housing, a lens, an acoustic foam, and a retaining mesh. The baffle housing includes a front panel having a channel, and first and second side panels. The first side panel is placed in physical contact with a first panel of a server chassis, and the second side panel is placed in physical contact with a second panel of the server chassis. The lens is in physical contact with the baffle housing, and fits within the channel of the front panel. The acoustic foam is in physical contact with the baffle housing, and includes an acoustic surface to absorb noise generated by cooling fans within the server chassis. The retaining mesh is in physical contact with the acoustic foam, and holds the acoustic foam within the acoustical baffle.

First claim

What is claimed is:

1. An acoustical baffle comprising:
a baffle housing including a front panel having a channel, and first and second side panels, the first side panel to be placed in physical contact with a first panel of a server chassis, and the second side panel to be placed in physical contact with a second panel of the server chassis;
a lens in physical contact with the baffle housing, the lens to fit within the channel of the front panel;
an acoustic foam in physical contact with the baffle housing, the acoustic foam including an acoustic surface to absorb noise generated by cooling fans within the server chassis; and
a retaining mesh in physical contact with the acoustic foam, the retaining mesh to hold the acoustic foam within the acoustical baffle.

2. The acoustical baffle of claim 1 , the lens includes a spacer to extend through the acoustic foam and the retaining mesh, the spacer to provide a line-of-sight from the front panel of the baffle housing to a light emitting diode on a first cooling fan within the server chassis.

3. The acoustical baffle of claim 1 , the baffle housing further including:
a first tab within a first opening of the first side panel, the first tab to extend away from the front panel; and
a first hook at an end of the first tab opposite the front panel, the first hook to snap fit on the first panel of the server chassis to securely connect the acoustical baffle to the server chassis.

4. The acoustical baffle of claim 3 , the baffle housing further including:
a second tab within a second opening of the second side panel, the second tab to extend away from the front panel; and
a second hook at an end of the second tab opposite the front panel, the second hook to snap fit on the second panel of the server chassis to securely connect the acoustical baffle to the server chassis.

5. The acoustical baffle of claim 4 , wherein the first and second tabs and the first and second hooks enable the acoustical baffle a tool less attachment to and removal from the server chassis.

6. The acoustical baffle of claim 1 , the baffle housing includes a peg to be placed in physical contact with a catch of the lens, wherein the physical contact between the peg and the catch hold the lens within the channel of the front panel.

7. The acoustical baffle of claim 1 , the baffle housing includes a hook to be placed in physical contact with a retaining opening of the retaining mesh, wherein the physical contact between the hook and the retaining opening holds the retaining mesh a particular distance from the front panel.

8. The acoustical baffle of claim 1 , wherein the retaining mesh is a particular distance from the cooling fans when the acoustical baffle is connected to the server chassis, wherein the particular distance optimizes air flow within the server chassis.

9. An information handling system comprising:
a server chassis including first and second panels, a plurality of cooling fans, and a plurality of compute devices cooled by the cooling fans; and
an acoustical baffle to be placed in physical contact with the server chassis, the acoustical baffle including:
a baffle housing including a front panel having a channel, and first and second side panels, the first side panel to be placed in physical contact with the first panel of the server chassis, and the second side panel to be placed in physical contact with the second panel of the server chassis;
a lens in physical contact with the baffle housing, the lens to fit within the channel of the front panel;
an acoustic foam in physical contact with the baffle housing, the acoustic foam including an acoustic surface to absorb noise generated by cooling fans within the server chassis; and
a retaining mesh in physical contact with the acoustic foam, the retaining mesh to hold the acoustic foam within the acoustical baffle.

10. The information handling system of claim 9 , the lens includes a spacer to extend through the acoustic foam and the retaining mesh, the spacer to provide a line-of-sight from the front panel of the baffle housing to a light emitting diode on a first cooling fan within the server chassis.

11. The information handling system of claim 9 , the baffle housing further including:
a first tab within a first opening of the first side panel, the first tab to extend away from the front panel; and
a first hook at an end of the first tab opposite the front panel, the first hook to snap fit on the first panel of the server chassis to securely connect the acoustical baffle to the server chassis.

12. The information handling system of claim 11 , the baffle housing further including:
a second tab within a second opening of the second side panel, the second tab to extend away from the front panel; and
a second hook at an end of the second tab opposite the front panel, the second hook to snap fit on the second panel of the server chassis to securely connect the acoustical baffle to the server chassis.

13. The information handling system of claim 12 , wherein the first and second tabs and the first and second hooks enable the acoustical baffle a tool less attachment to and removal from the server chassis.

14. The information handling system of claim 9 , the baffle housing includes a peg to be placed in physical contact with a catch of the lens, wherein the physical contact between the peg and the catch hold the lens within the channel of the front panel.

15. The information handling system of claim 9 , the baffle housing includes a hook to be placed in physical contact with a retaining opening of the retaining mesh, wherein the physical contact between the hook and the retaining opening holds the retaining mesh a particular distance from the front panel.

16. The information handling system of claim 9 , wherein the retaining mesh is a particular distance from the cooling fans when the acoustical baffle is connected to the server chassis, wherein the particular distance optimizes air flow within the server chassis.

17. An acoustical baffle comprising:
a baffle housing including a front panel having a channel, and first and second side panels, the first side panel to be placed in physical contact with a first panel of a server chassis, and the second side panel to be placed in physical contact with a second panel of the server chassis, the first side panel having:
a first tab within a first opening of the first side panel, the first tab to extend away from the front panel; and
a first hook at an end of the first tab opposite the front panel, the first hook to snap fit on the first panel of the server chassis to securely connect the acoustical baffle to the server chassis;

an acoustic foam in physical contact with the baffle housing, the acoustic foam including an acoustic surface to absorb noise generated by cooling fans within the server chassis;
a retaining mesh in physical contact with the acoustic foam, the retaining mesh to hold the acoustic foam within the acoustical baffle; and
a lens in physical contact with the baffle housing, the lens to fit within the channel of the front panel, the lens includes a spacer to extend through the acoustic foam and the retaining mesh, the spacer to provide a line-of-sight from the front panel of the baffle housing to a light emitting diode on a first cooling fan within the server chassis.

18. The acoustical baffle of claim 17 , wherein the first and second tabs and the first and second hooks enable the acoustical baffle a tool less attachment to and removal from the server chassis.

19. The acoustical baffle of
