Heat sink filler for matched impedance of air flow
A heat sink filler to maintain proper cooling air flow through operating processing units is disclosed. The heat sink filler comprises a frame with a removable perforated sheet inside the frame, wherein the perforated sheet is configured to match an impedance of a heat sink. The heat sink filler further includes a first keying feature. The heat sink filler also includes an extended edge on a first edge of the frame and a beveled edge on the second edge of the frame.
1 . A heat sink filler comprising:
a frame;
a removable perforated sheet inside the frame;
a first keying feature;
an extended edge on a first edge of the frame; and
a beveled edge on a second edge of the frame, wherein the second edge is parallel to the first edge.
2 . The heat sink filler of claim 1 , wherein a bottom edge of the frame is configured to latch onto a dust cover, wherein the bottom edge connects the first edge and the second edge of the frame.
3 . The heat sink filler of claim 2 , wherein the first keying feature ensures the frame connect to the dust cover in a correct location.
4 . The heat sink filler of claim 3 , further comprising:
a second keying feature, wherein the second keying feature is an asymmetrical keying feature, the second keying feature interlocks with a dust cover asymmetrical keying feature, and the second keying feature ensures a correct orientation of the frame relative to the dust cover.
5 . The heat sink filler of claim 1 , wherein the extended edge is configured to overlap with a recessed edge of a first adjacent component.
6 . The heat sink filler of claim 5 , wherein the beveled edge is configured to overlap with an adjacent extended edge of a second adjacent component.
7 . The heat sink filler of claim 6 , wherein the extended edge and the beveled edge create a wall to prevent air passing in between the heat sink filler and the first adjacent component, and the heat sink filler and the second adjacent component.
8 . The heat sink filler of claim 1 , wherein the heat sink filler is configured to replace the heat sink in a server drawer.
9 . The heat sink filler of claim 1 , wherein the perforated sheet is an inlet side for a cooling air flow, the heat sink filler further comprising:
a set of louvers on an output side for the cooling air flow, wherein the louvers are configured to replicate a depth of the heat sink by interacting with the air flow after passing through the set of louvers.
10 . The heat sink filler of claim 2 , further comprising:
a release lever, wherein the release lever, when pushed towards the frame, allows the heat sink filler to be removed from the dust cover.
11 . The heat sink filler of claim 2 , further comprising:
a dual lever connector, wherein the dual lever connector comprises two levers that, when pushed towards each other, allow the heat sink filler to be removed from the dust cover.
