Abstract
Embodiments may utilize a series of exposed fins, which increase the surface area of the heat sink creating additional air flow. As hotter air rises within the system, cooler is drawn into the heatsink. The fins may be exposed on both sides of the longitudinal axis, allowing cooler air to be drawn towards the longitudinal axis above the heatsink and flow upward. This process may cool the fins. Additionally, the spacing between the fins may have to be wide enough to allow for air to freely enter the heatsink.
Claims20
A heat sink comprising:
- a unitary sheet of metal that is configured to be folded over itself to form a series of plurality of alternating first chambers and second chambers;
- a first chamber being one of the plurality of first chambers, the first chamber being formed of a first fin and a second fin, and the first chamber having a first open lower surface;
- a second chamber being one of the plurality of second chambers, the second chamber being formed of the second fin and a third fin, the second chamber having a second open upper surface and a second closed lower surface, wherein the first chamber is positioned adjacent to the second chamber.
A method of forming a heat sink comprising:
- folding a unitary sheet of metal over itself to form a series of plurality of alternating first chambers and second chambers, wherein a first chamber of the plurality of first chambers being formed of a first fin and a second fin, and the first chamber having a first open lower surface, and a second chamber of the plurality of second chambers being formed of the second fin and a third fin, the second chamber having a second open upper surface and a second closed lower surface, wherein the first chamber is positioned adjacent to the second chamber.
