Abstract

A tool-less heat spreader for dissipating heat produced by an electrical computing component includes a first section having a flexible thermal interface material for engaging either side of the electrical computing component; and a rigid heat shield pivotally connected to the first section, the rigid heat shield pivoting between one of a first position and a second position.

First claim

What is claimed is:

1. A tool-less heat spreader for dissipating heat produced by an electrical computing component, comprising:
a first section having a flexible thermal interface material for engaging both side of the electrical computing component; and
a rigid heat shield pivotally connected to the first section, the rigid heat shield pivoting between one of a first position and a second position; wherein the first position is an open position and the second position is a closed position, the rigid heat shield pivoting up and away from the first section when in the open position, the rigid heat shield covering and compressing the first section onto the electrical computing component when in the closed position, wherein the rigid heat shield comprises two parallel sections, wherein the two parallel sections form a fist lateral side, wherein the first lateral side comprises a formed connection between the two parallel sections, and a plurality of fins in a middle section of the first lateral side, wherein the two parallel sections form a second lateral side, wherein the second lateral side is open and formed for sliding the rigid heat shield over the first section of the heat spreader; and
wherein the rigid heat shield is pivotally connected to the first section of the heat spreader through an aperture in an upper surface of the two parallel sections; and wherein the first section of the heat spreader and the rigid heat shield pivotally connected thereto are freestanding and portable.

2. The heat spreader of claim 1 , wherein the flexible thermal interface material comprises two parallel sections connected at an upper surface, and formed such for sliding the first section over the electrical computing component.

3. The heat spreader of claim 1 , further including a pivot connector for pivotally connecting the rigid heat shield to the first section.

4. The heat spreader of claim 1 , further including a finger grip formed into the upper surface of the rigid heat shield.

5. The heat spreader of claim 1 , wherein the electrical computing component comprises a Dual-Inline Memory Module (DIMM).

6. A tool-less heat spreader for dissipating heat produced by an electrical computing component, comprising:
a first section having a flexible thermal interface material formed to cover and engage surfaces of both sides of the electrical computing component; and
a rigid heat shield pivotally connected at one end of the first section and formed to cover the first section, the rigid heat shield pivoting between one of a first position and a second position; wherein the first position is an open position and the second position is a closed position, the rigid heat shield pivoting up and away from the first section when in the open position, and covering and compressing the first section onto the electrical computing component when in the closed position; wherein the rigid heat shield comprises two parallel sections, wherein the two parallel sections form a fist lateral side, wherein the first lateral side comprises a formed connection between the two parallel sections, and a plurality of fins in a middle section of the first lateral side, wherein the two parallel sections form a second lateral side, wherein the second lateral side is open and formed for sliding the rigid heat shield over the first section of the heat spreader; and
wherein the rigid heat shield is pivotally connected to the first section through an aperture in an upper surface of the two parallel sections; and wherein the first section of the heat spreader and the rigid heat shield pivotally connected thereto are freestanding and portable.

7. The heat spreader of claim 6 , wherein the flexible thermal interface material comprises two parallel sections connected at an upper surface, and formed such for sliding the first section over the electrical computing component.

8. The heat spreader of claim 6 , further including a pivot connector for pivotally connecting the rigid heat shield to the first section.

9. The heat spreader of claim 6 , further including a finger grip formed into the upper surface of the rigid heat shield.

10. The heat spreader of claim 6 , wherein the electrical computing component comprises a Dual-Inline Memory Module (DIMM).

11. A method of manufacturing a tool-less heat spreader for dissipating heat produced by an electrical computing component, comprising:
forming a first section having a flexible thermal interface material for engaging both side of the electrical computing component; and
forming a rigid heat shield pivotally connected to the first section, the rigid heat shield pivoting between one of a first position and a second position; wherein the first position is an open position and the second position is a closed position, the rigid heat shield pivoting up and away from the first section when in the open position, the rigid heat shield covering and compressing the first section onto the electrical computing component when in the closed position; wherein the rigid heat shield comprises two parallel sections, wherein the two parallel sections form a fist lateral side, wherein the first lateral side comprises a formed connection between the two parallel sections, and a plurality of fins in a middle section of the first lateral side, wherein the two parallel sections form a second lateral side, wherein the second lateral side is open and formed for sliding the rigid heat shield over the first section of the heat spreader; and
wherein the rigid heat shield is pivotally connected to the first section of the heat spreader through an aperture in an upper surface of the two parallel sections; and wherein the first section of the heat spreader and the rigid heat shield pivotally connected thereto are freestanding and portable.

12. The method of claim 11 , wherein the flexible thermal interface material comprises two parallel sections connected at an upper surface, and formed such for sliding the first section over the electrical computing component.

13. The method of claim 11 , further including a pivot connector for pivotally connecting the rigid heat shield to the first section.

14. The method of claim 11 , further including forming a finger grip into the upper surface of the rigid heat shield.

15. The method of claim 11 , wherein the electrical computing component comprises a Dual-Inline Memory Module (DIMM).
