Abstract
Hose barb fittings and apparatuses described herein provide increased fluid-flow rates for cooling loops used for thermal control in computer system. A hose barb fitting comprises a fluid-flow passage that extends through the hose barb fitting from a first opening to a second opening. The ratio of the cross-sectional area of the fluid-flow passage to the cross-sectional area of the hose barb fitting is between 0.4 and 0.7, inclusive. When the hose barb fitting is fully seated within a housing structure, a specialized gasket acts as both a radial seal and a face seal. Also, a flange extending from the housing structure engages with a flange extending from the hose barb fitting to prevent the hose barb fitting from being unseated.
Claims20
An apparatus comprising:
- a hose barb fitting comprising:
- a first opening at a first end of the hose barb fitting,
- a second opening at a second end of the hose barb fitting,
- a fluid-flow passage that extends through the hose barb fitting from the first opening to the second opening, wherein a ratio of a cross-sectional area of the fluid-flow passage to a cross-sectional area of the hose barb fitting is between 0.4 and 0.7, inclusive,
- a first flange proximal to the first end of the hose barb fitting, wherein the first flange extends outward from an outer surface of the hose barb fitting, and
- a recess on the outer surface of the hose barb fitting extending along a cross-sectional outer perimeter of the hose barb fitting, wherein a ratio of a length of the recess in a fluid-flow direction for the first opening to a cross-sectional width of the fluid-flow passage is between 0.5 and 0.9, inclusive;
- a housing structure comprising:
- a socket, wherein the first end of the hose barb fitting rests inside the socket when the hose barb fitting is fully seated within the housing structure, and
- a second flange that engages with the first flange to prevent the first end of the hose barb fitting from exiting the socket when the hose barb fitting is fully seated within the housing structure;
- and
- a gasket that rests in the recess on the outer surface of the hose barb fitting when the hose barb fitting is fully seated within the housing structure, the gasket comprising:
- an anterior portion that rests within the socket and presses radially outward relative to the fluid-flow direction for the first opening against an inner surface of the socket when the hose barb fitting is fully seated within the housing structure, and
- a posterior portion that rests outside of the socket and presses against an outer surface of the housing structure that is orthogonal to the fluid-flow direction for the first opening when the hose barb fitting is fully seated within the housing structure.
An apparatus comprising:
- a hose barb fitting comprising:
- a first opening at a first end of the hose barb fitting,
- a second opening at a second end of the hose barb fitting,
- a fluid-flow passage that extends through the hose barb fitting from the first opening to the second opening, wherein a ratio of a cross-sectional area of the fluid-flow passage to a cross-sectional area of the hose barb fitting is between 0.4 and 0.7, inclusive,
- a first flange proximal to the first end of the hose barb fitting, wherein the first flange extends outward from an outer surface of the hose barb fitting, and
- a recess on the outer surface of the hose barb fitting extending along a cross-sectional outer perimeter of the hose barb fitting, wherein a ratio of a length of the recess in a fluid-flow direction for the first opening to a cross-sectional width of the fluid-flow passage is between 0.5 and 0.9, inclusive;
- and
- a gasket that rests in the recess on the outer surface of the hose barb fitting, the gasket comprising:
- an anterior portion that is proximal relative to the first opening and presses radially inward on the hose barb fitting relative to the fluid-flow direction for the first opening, wherein subtracting an inner radius of the anterior portion from an outer radius of the anterior portion yields a first difference, and
- a posterior portion that is distal relative to the first opening, wherein subtracting an inner radius of the posterior portion from an outer radius of the posterior portion yields a second difference that is larger than the first difference.
A hose barb fitting comprising:
- a first opening at a first end of the hose barb fitting;
- a second opening at a second end of the hose barb fitting;
- a fluid-flow passage that extends through the hose barb fitting from the first opening to the second opening, wherein a ratio of a cross-sectional area of the fluid-flow passage to a cross-sectional area of the hose barb fitting is between 0.4 and 0.7, inclusive;
- a flange proximal to the first end of the hose barb fitting, wherein the flange extends outward from an outer surface of the hose barb fitting;
- and
- a recess on the outer surface of the hose barb fitting extending along a cross-sectional outer perimeter of the hose barb fitting, wherein a ratio of a length of the recess in a fluid-flow direction for the first opening to a cross-sectional width of the fluid-flow passage is between 0.5 and 0.9, inclusive.
