Abstract
A cold plate apparatus includes walls that surround an active volume adjacent to an inlet plenum; the walls include an inlet opening at one end of a top side of the inlet plenum and a plenum opening between the inlet plenum and the active volume. Also included is a blocker that partially separates the inlet plenum from the active volume. The blocker is structurally configured to preferentially redirect flow from the inlet plenum into the active volume.
Claims9
A cold plate apparatus comprising:
- walls that surround an active volume adjacent to an inlet plenum, wherein the walls include an inlet opening at one end of a top side of the inlet plenum and a plenum opening between the inlet plenum and the active volume, wherein the walls comprise a top plate, a bottom plate, and a stack of at least three intermediate plates between the top plate and the bottom plate;
- and
- a blocker that partially separates the inlet plenum from the active volume, wherein the blocker is structurally configured to preferentially redirect flow from the inlet plenum into the active volume;
- wherein portions of the at least three intermediate plates form a deflector that protrudes from an outer wall of the inlet plenum toward the active volume, and wherein a bottommost of the intermediate plates protrudes further toward the active volume than does a topmost of the intermediate plates.

- and
- a blocker that partially separates the inlet plenum from the active volume, wherein the blocker is structurally configured to preferentially redirect flow from the inlet plenum into the active volume;
- wherein the blocker blocks more of the plenum opening near a bottom side of the plenum opening opposite the inlet opening than is blocked near a top side of the plenum opening near the inlet opening;
- wherein the blocker comprises a plurality of N fingers extending from the inlet opening along the inlet plenum, a lowest finger being longest and an uppermost finger being shortest;
- and
- wherein the lowest finger is a length L, the uppermost finger is a length L/N, and each finger ascending from lowest to uppermost is L/N shorter than a next lower finger.
