Abstract

A cold plate base is provided. The cold plate includes a fluid intake region located at a distal end of the cold plate, and a fluid outtake region located at a proximal end of the cold plate that is opposite the distal end. The cold plate also includes a fin region positioned between the fluid intake region and the fluid outtake region. The fin region extends from a base surface of the cold plate base. The cold plate also includes a plurality of protrusions at the fluid intake region. Each of the plurality of protrusions radiates from the fluid intake region to create flow paths across the fin region.

First claim

What is claimed is:

a fluid intake region located at a distal end of the cold plate, and a fluid outtake region located at a proximal end of the cold plate that is opposite the distal end;
a fin region positioned between the fluid intake region and the fluid outtake region, wherein the fin region extends from a base surface of the cold plate base, the fin region comprising at least one wall region, the at least one wall region comprising a plurality of elongated walls configured in a non-matrix arrangement; and
a plurality of protrusions at the fluid intake region, wherein each of the plurality of protrusions radiates from the fluid intake region to create flow paths across the fin region.

2. The cold plate base of claim 1 ,
wherein the plurality of protrusions has a central axis, and each of the plurality of protrusions is symmetrical about the central axis.

3. The cold plate base of claim 1 , wherein the fin region comprises at least one region comprising multiple rows of fins in addition to the at least one wall region, each wall region separated from an adjacent region comprising the multiple rows of fins by a fin region gap.

4. The cold plate of claim 3 , wherein the flow paths are evenly spaced about the plurality of wall regions.

5. The cold plate base of claim 1 , wherein the base surface of the cold plate base beneath the fin region has a thickness of up to 2 millimeters.

6. The cold plate base of claim 1 , wherein the base surface of the cold plate base beneath the fin region comprises a conductive flexible material.

7. A cooling apparatus comprising:
a radiator; and
a cold plate connected to the radiator by at least two fluid tubes, the cold plate comprising a cold plate base comprising:
a fluid intake region located at a distal end of the cold plate, and a fluid outtake region located at a proximal end of the cold plate that is opposite the distal end;
a fin region positioned between the fluid intake region and the fluid outtake region, wherein the fin region extends from a base surface of the cold plate base, the fin region comprising at least one wall region, the at least one wall region comprising a plurality of elongated walls configured in a non-matrix arrangement; and
a plurality of protrusions at the fluid intake region, wherein each of the plurality of protrusions radiates from the fluid intake region to create flow paths across the fin region.

8. The cooling apparatus of claim 7 ,
wherein the plurality of protrusions has a central axis, and each of the plurality of protrusions is symmetrical about the central axis.

9. The cooling apparatus of claim 7 , wherein the fin region comprises at least one region comprising multiple rows of fins in addition to the at least one wall region, each wall region separated from an adjacent region comprising the multiple rows of fins by a fin region gap.

10. The cooling apparatus of claim 9 , wherein the flow paths are evenly spaced about the plurality of wall regions.

11. The cooling apparatus of claim 7 , wherein the base surface of the cold plate base beneath the fin region has a thickness of up to 2 millimeters.

12. The cooling apparatus of claim 7 , wherein the base surface of the cold plate base beneath the fin region comprises a conductive flexible material.

13. The cooling apparatus of claim 7 ,
wherein the cold plate further comprises a cold plate cover configured to cover the cold plate base, the cold plate cover comprises a fluid intake aperture aligned with the fluid intake region and a fluid outtake aperture aligned with the fluid outtake region.

14. The cooling apparatus of claim 7 ,
wherein the cold plate is configured to be coupled with an electrical component.

15. A server device comprising:
at least one electronic component; and
a cooling apparatus configured to couple with the at least one electronic component, the cooling apparatus comprising:
a radiator; and
a cold plate connected to the radiator by at least two fluid tubes, the cold plate comprising a cold plate base comprising:
a fluid intake region located at a distal end of the cold plate, and a fluid outtake region located at a proximal end of the cold plate that is opposite the distal end;
a fin region positioned between the fluid intake region and the fluid outtake region, wherein the fin region extends from a base surface of the cold plate base, the fin region comprising at least one wall region, the at least one wall region comprising a plurality of elongated walls configured in a non-matrix arrangement; and
a plurality of protrusions at the fluid intake region, wherein each of the plurality of protrusions radiates from the fluid intake region to create flow paths across the fin region.

16. The server device of claim 15 ,
wherein the plurality of protrusions has a central axis, and each of the plurality of protrusions is symmetrical about the central axis.

17. The server device of claim 16 , wherein the fin region comprises at least one region comprising multiple rows of fins in addition to the at least one wall region, each wall region separated from an adjacent region comprising the multiple rows of fins by a fin region gap.

18. The server device of claim 17 , wherein the flow paths are evenly spaced about the plurality of wall regions.

19. The server device of claim 15 , wherein the base surface of the cold plate base beneath the fin region has a thickness of up to 2 millimeters.

20. The server device of claim 15 , wherein the base surface of the cold plate base beneath the fin region comprises a conductive flexible material.
