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.
Claims15
A fluid cooled cold plate comprising:
- a main coolant passage having a first cross-sectional area taken laterally in a direction perpendicular to the flow direction;
- a finned coolant passage having a second cross-sectional area taken laterally in a direction perpendicular to the flow direction, wherein the second area is smaller than the first area;
- a branch fluidly connecting the main coolant passage with the finned coolant passage, wherein the branch is oriented such that a fluid is turned 90° or more when passing 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.
A method for preventing cooling flow blockage in a fluid cooled cold plate, the method comprising:
- passing a fluid with an entrained contaminate through a main coolant passage having a first cross-sectional area taken laterally in a direction perpendicular to the flow direction;
- bypassing a fluid with an entrained contaminate larger than a finned coolant passage past a branch, wherein the branch is oriented such that the fluid is turned 90° or more when passing 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 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;
- and
- directing the fluid with the entrained contaminate 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.
