Abstract

In one embodiment, an apparatus includes a monolithically formed thermal conducting body that includes a passageway that extends from a first end to a second end of the body. At least one of the first end or the second end of the body is configured to couple the body to a tubular member. The body also defines a substantially non-circular outer perimeter, and at least a portion of the passageway of the body defines a substantially circular cross-section. The passageway of the body is configured to receive fluid there through, and the body has a substantially planar outer surface that is configured to be placed in contact with a heat generating component. In some embodiments, the body can be coupled to a plate. In some embodiments, an apparatus can include more than one such thermal conducting body.

Claims

1. An apparatus, comprising:

a plate comprising a substantially planar surface;

an elongate body coupled to the plate, the elongate body including a substantially planar surface, a first end, a second end and defining a passageway configured to receive a fluid there through, the elongate body being coupled to the plate within a circumference of the substantially planar surface of the plate such that the substantially planar surface of the elongate body is generally flush with the substantially planar surface of the plate, and wherein, the planar surfaces of the elongate body and the plate are configured to be placed in contact with an electronic component; and

a tubular member coupled to the plate, an end of the tubular member coupled to the first end of the elongate body such that a passageway of the tubular member is in communication with the passageway of the elongate body.

2. The apparatus of claim 1, wherein the elongate body and plate substantially planar surfaces are configured to couple to the electronic component.

3. The apparatus of claim 1, wherein the elongate body planar surface is an upper surface of the elongate body.

4. The apparatus of claim 1, wherein the second end of the elongate body is configured to be coupled to a source of fluid.

5. The apparatus of claim 1, wherein the tubular member is directly coupled to a first side of the plate and the elongate body is directly coupled to an opposing side of the plate.

6. The apparatus of claim 1, wherein the elongate body is a first elongate body, the apparatus further comprising:

a second elongate body coupled to the plate within a circumference of the substantially planar surface of the plate, the second elongate body including a first end and a second end and defining a passageway configured to receive a fluid,

the end of the tubular member being a first end, the tubular member including a second end coupled to the first end of the second elongate body such that the passageway of the tubular member is in communication with the passageway of the second elongate body.

7. The apparatus of claim 1, wherein an axis defined by the elongate body is substantially parallel to an axis defined by the tubular member.

8. The apparatus of claim 1, wherein the tubular member is threadedly coupled to the elongate body.

9. The apparatus of claim 1, wherein the plate has a first thermal resistance, the elongate body has a second thermal resistance different from the first thermal resistance.

10. The apparatus of claim 1, wherein the tubular member is sealingly coupled to the elongate body.

11. The apparatus of claim 1, wherein at least a portion of the passageway of the elongate body is substantially circular.

12. The apparatus of claim 1, wherein at least a portion of the passageway of the elongate body is substantially non-circular.

13. An apparatus, comprising:

a first body and a second body each including a first end and a second end and defining a passageway configured to receive a fluid there through, the first end of the first body configured to be coupled to an inlet pipe, the first end of the second body configured to be coupled to an outlet pipe; and

a tubular member defining a passageway, a first end of the tubular member coupled to the second end of the first body, a second end of the tubular member coupled to the second end of the second body such that the passageway of the tubular member is in communication with the passageway of the first body and the passageway of the second body; and

a plate having a planar surface, wherein,

the first and second bodies are at least partially disposed along the planar surface and are embedded within the plate so that each of the first and second bodies is coupled to the plate within a circumference of the planar surface of the plate and each of the first and second bodies have a surface that is co-planer with the planer surface of the plate, allowing thermal energy to distribute between the first and second bodies and the plate.

14. The apparatus of claim 13, wherein, at least one of the first and second bodies comprises an elongate body partially extending below the plate planar surface.

15. The apparatus of claim 13, wherein, at least one of the first and second bodies comprises an elongate body coupled onto the planar surface and extending outwardly from the outer planar surface.

16. An apparatus, comprising:

a first body and a second body each including a first end and a second end and defining a passageway configured to receive a fluid there through, the first end of the first body configured to be coupled to an inlet pipe, the first end of the second body configured to be coupled to an outlet pipe; and

a tubular member defining a passageway, a first end of the tubular member coupled to the second end of the first body, a second end of the tubular member coupled to the second end of the second body such that the passageway of the tubular member is in communication with the passageway of the first body and the passageway of the second body; and

a plate having a planar surface, wherein,

the first and second bodies are at least partially disposed along the planar surface and are embedded within the plate so that each of the first and second bodies is coupled to the plate within a circumference of the planar surface of the plate and each of the first and second bodies have a surface that is co-planer with the planer surface of the plate, allowing thermal energy to distribute between the first and second bodies and the plate;
