Abstract

Various embodiments of the present disclosure provide a heat sink for a plug-in storage card and a plug-in storage card including the heat sink. The heat sink comprises a first part secured to a surface of the plug-in storage card and a second part coupled to the first part and being movable relative to the first part in a first direction, wherein the first direction is perpendicular to the surface of the plug-in storage card. In this way, when the second part and the first part have a larger overlap in the first direction, the heat sink has a smaller first height and when the second part and the first part have a smaller overlap in the first direction, the heat sink has a greater second height.

First claim

What is claimed is:

1. A device, comprising:
a plug-in storage card;
a heat sink associated with the plug-in storage card, the heat sink comprising:
a first part mounted relative to the plug-in storage card, the first part including a plurality of first heat radiating elements;
a second part mounted relative to the plug-in storage card and opposing the first part, the second part including a plurality of second heat radiating elements extending toward the first part, the first part and the second part being configured for relative movement between a first relative position defining a first vertical height of the heat sink and a second relative position defining a second relative height of the heat sink, the first vertical height being greater than the second vertical height;
a transmission member operatively coupled to the plug-in storage card and to at least one of the first part or the second part, the transmission member movable to cause corresponding relative movement of the first and second parts and adjustment of the heat sink between the first and second vertical heights; and
a spring member operatively coupled to the transmission member and rotatably coupled to the plug-in storage card, the spring member configured to bias the first and second parts toward the first relative position.

2. The device of claim 1 , wherein the first part is secured to the plug-in storage card.

3. The device of claim 1 , wherein the transmission member is pivotally coupled to the plug-in storage card.

4. The device of claim 1 , wherein the transmission member is configured to translate in a direction corresponding to a length direction of the plug-in card.

5. A device, comprising:
a plug-in storage card;
a heat sink associated with the plug-in storage card, the heat sink comprising:
a first part mounted relative to the plug-in storage card, the first part including a plurality of first heat radiating elements;
a second part mounted relative to the plug-in storage card and opposing the first part, the second part including a plurality of second heat radiating elements extending toward the first part, the first part and the second part being configured for relative movement to adjust a vertical height of the heat sink; and
a first transmission member coupled to the plug-in storage card and operatively coupled to one of the first and second parts, the first transmission member movable to cause corresponding relative movement of the first and second parts to adjust the vertical height of the heat sink;

wherein the second part is movably coupled to the plug-in storage card, the second part movable relative to the first part to adjust the vertical height of the heat sink;
wherein the first transmission member is operatively coupled to the second part and pivotally coupled to the plug-in storage card; and
wherein pivotal movement of the first transmission member causes movement of the second part to adjust the vertical height of the heat sink.

6. The device of claim 5 , wherein the first heat radiating elements of the first part and the second heat radiating elements of the second part at least partially overlap when in at least one relative position of the first and second parts.

7. The device of claim 6 , wherein the second part is movable relative to the first part between at least first and second relative positions of the first and second parts;
wherein in the first relative position, corresponding to a first height of the heat sink, the first heat radiating elements and the second heat radiating elements define a first degree of overlap;
wherein in the second relative position, corresponding to a second height of the heat sink, the first heat radiating elements and the second heat radiating elements define a second degree of overlap greater than the first degree of overlap; and
wherein the first height of the heat sink is greater than the second height of the heat sink.

8. The device of claim 7 , wherein individual ones of the first heat radiating elements and individual ones of the second heat radiating elements are staggered relative to each other.

9. The device of claim 7 , wherein individual ones of the first heat radiating elements and individual ones of the second heat radiating elements are aligned relative to each other and disposed in telescopic arrangement.

10. The device of claim 5 , wherein the first part is secured to the plug-in storage card.

11. The device of claim 5 , including a second transmission member mounted relative to the heat sink and operatively coupled to the first transmission member, the second transmission member movable to cause pivotal movement of the first transmission member to thereby cause movement of the second part to adjust the vertical height of the heat sink.

12. The device of claim 11 , including a first torsion spring mounted relative to the plug-in storage card and operatively coupling the first transmission member and the second transmission member.

13. The device of claim 11 , including a manually engageable member operatively coupled to the second transmission member, the manually engageable member movable by a user to cause movement of the second transmission member and corresponding pivotal movement of the first transmission member to adjust the vertical height of the heat sink.

14. The device of claim 13 , including a second torsion spring mounted relative to the plug-in storage card and operatively coupling the manually engageable member and the second transmission member;
wherein movement of the manually engageable member by the user causes the second transmission member to move in one direction and correspondingly reduce the vertical height of the heat sink; and
wherein release of the manually engageable member permits the second transmission member to move in an opposite direction in response to a bias of the second torsion spring and correspondingly increase the vertical height of the heat sink.

15. A heat sink for a plug-in storage card, comprising:
a first part mounted relative to the plug-in storage card, the first part including a plurality of first heat radiating elements extending in a first direction;
a second part mounted relative to the plug-in storage card and opposing the first part, the second part including a plurality of second heat radiating elements extending in a second direction opposing the first direction toward the first part, the first part and the second part being configured for relative movement to adjust a vertical height of the heat sink; and
a first transmission member configured to be coupled to the plug-in storage card and operatively coupled to one of the first and second parts, the first transmission member movable to cause corresponding relative movement of the first and second parts to adjust the vertical height of the heat sink;
wherein the first part is configured to be secured to the plug-in storage card;
wherein the second part is operatively coupled to the first transmission member, the first transmission member configured to be pivotally coupled to the plug-in storage card; and
wherein pivotal movement of the first transmission member causes corresponding movement of the second part to adjust the vertical height of the heat sink.

16. The heat sink of claim 15 , wherein the second part is movable relative to the first part between at least first and second relative positions of the first and second parts;
wherein in the first relative position, corresponding to a first height of the heat sink, the first heat radiating elements and the second heat radiating elements define a first degree of ov
