Prevention of cooling flow blockage
First Claim
1. A fluid cooled cold plate comprising:
- a main coolant passage having a first cross-sectional area taken laterally in a direction perpendicular to a flow direction of the main coolant passage;
a finned coolant passage having a second cross-sectional area taken laterally in a direction perpendicular to the flow direction of the main coolant passage, wherein the second cross-sectional area is smaller than the first cross-sectional area;
a branch fluidly connecting the main coolant passage with the finned coolant passage, wherein the branch is turned more than 90°
from the flow direction of the main coolant passage, such that fluid flowing through the branch is reversed from the flow direction of the main coolant passage by turning more than 90°
from the flow direction of the main coolant passage to prevent contaminants from flowing into the branch from the main coolant passage; and
a coolant bypass passage in fluid communication with the main coolant passage and located fluidically parallel to the finned coolant passage such that fluid configured to flow through the fluid cooled cold plate passes through either the coolant bypass passage or the finned coolant passage.

Abstract
A fluid cooled cold plate includes a main coolant passage with a first cross-sectional area taken laterally in a direction perpendicular to the flow direction and a finned coolant passage having a second cross-sectional area taken laterally in a direction perpendicular to the flow direction, with the second area smaller than the first area. Fluidly connecting the main coolant passage with the finned coolant passage is a branch oriented such that a fluid is turned 90° or more when passing into the branch from the main coolant passage. Also included is a coolant bypass passage in fluid communication with the main coolant passage and located fluidically parallel to the finned coolant passage.

9. A method for preventing a cooling flow blockage in a fluid cooled cold plate, the method comprising:
-
passing a fluid with entrained contaminants that are larger than a finned coolant passage through a main coolant passage having a first cross-sectional area taken laterally in a direction perpendicular to a flow direction of the main coolant passage; bypassing a first portion of the fluid with the entrained contaminants larger than the finned coolant passage past a branch, wherein the branch is turned more than 90°
from the flow direction of the main coolant passage, such that a second portion of the fluid is reversed from the flow direction of the main coolant passage by turning more than 90°
from the flow direction of the main coolant passage to prevent the entrained contaminants larger than the finned coolant passage from flowing into the branch from the main coolant passage, and wherein the branch is in fluid connection with the main coolant passage on a first end and the finned coolant passage on a second end, the finned coolant passage having a second cross-sectional area taken laterally in a direction perpendicular to the flow direction, and wherein the second area is smaller than the first area; anddirecting the first portion of the fluid with the entrained contaminants larger than the finned coolant passage through a coolant bypass passage in fluid communication with the main coolant passage and fluidically parallel to the finned coolant passage such that fluid configured to flow through the fluid cooled cold plate passes through either the coolant bypass passage or the finned coolant passage. - View Dependent Claims (10, 11, 12, 13, 14, 15)
