Abstract

A heat transfer device for use with a retention assembly is herein disclosed. The retention assembly is mounted over one or more connectors attached to a circuit board. The retention assembly houses one or more processor modules that mount into the connectors. The processor modules include a heat transfer device. The heat transfer device has a pair of rail guides that cover the outer edges of the processor module. The rail guides enable the processor module to slide in and out of the retention assembly thereby enabling the processor module to be securely mounted into the connector.

Claims

1. A heat transfer apparatus for use with an electronic package that is housed in a retention mechanism, comprising:

a base portion;

a first rail guide coupled to the base portion and being detachably removable to the retention mechanism;

a second rail guide coupled to the base portion and being detachably removable to the retention mechanism;

the base portion including a first flange and a second flange, the first flange coupled to the first guide and the second flange coupled to the second guide;

wherein the retention mechanism includes a first and second lock mechanism;

wherein the first flange is used by the first lock mechanism to secure the heat transfer apparatus to the retention mechanism;

wherein the second flange is used by the second lock mechanism to secure the heat transfer apparatus to the retention mechanism.

2. The apparatus of claim 1,

wherein the electronic package includes a plurality of electronic components;

and

wherein the base portion is in thermal contact with a subset of said electronic components.

3. The apparatus of claim 2,

wherein the subset includes a select one of said electronic components.

4. The apparatus of claim 1,

wherein the first and second rail guides are coupled to opposite sides of the base portion.

5. The apparatus of claim 1, including:

a finned heat radiating member extending upward and outward from said base portion.

6. The apparatus of claim 1,

wherein the base portion includes a bottom surface that is in thermal contact with the electronic package;

at least one thermal compound coupled to the bottom surface of the base portion and for improving the thermal cooling of the heat transfer device.

7. The apparatus of claim 6,

a first thermal compound positioned in a first position on the bottom surface of the base portion, the first thermal compound is formed of a phase change thermal material;

and

a second thermal compound positioned in a second position on the bottom surface of the base portion, the second thermal compound is formed of a non-phase thermal material.

8. A heat sink for use with a retention assembly including a first wall, a second wall, a first lock lever, and a second lock lever, the first wall parallel to the second wall, the first wall including a first rail and the second wall including a second rail, the heat sink comprising:

a base portion having a flat planar surface with a first edge and a second edge, the first edge opposite the second edge, the base portion including a first and second flange, the first flange for use with the first lock lever to secure the heat sink to the retention assembly, the second flange for use with the second lock lever to secure the heat sink to the retention assembly;

a finned heat radiating member extending upward and outward from said base portion; and

a first and second rail guides for removably mounting the heat sink into the retention assembly, the first rail guide coupled to the first edge of the base portion and fitted to slide into the first rail, the second rail guide coupled to the second edge of the base portion and fitted to slide into the second rail.

9. The heat sink of claim 8,

the base portion including a base pedestal that is in thermal contact with an electronic component.

10. The heat sink of claim 8,

the base portion including a base pedestal that is in thermal contact with a plurality of electronic components.
