Abstract

A heat sink with angled fins comprising a first set of fins forming air channels, a second set of fins forming air channels and a heat sink base coupled to the first set of fins and the second set of fins. The first set of fins and the second set of fins are separated by a region along a length of the heat sink base. The fins in the first set of fins are at a first angle with respect to the length of the heat sink base and the fins in the second set of fins are at a second angle with respect to the length of the heat sink base.

Claims (44)

1. A heat sink with angled fins comprising:

a first set of fins forming air channels;

a second set of fins forming air channels;

a heat sink base having a surface forming a plane coupled to the first set of fins and the second set of fins, wherein the first set of fins and the second set of fins are separated by a region along a length of the heat sink base, and wherein the fins in the first set of fins are perpendicular to the plane of the heat sink base and are positioned along the length of the heat sink base at a first acute angle with respect to the length of the heat sink base, and wherein the fins in the second set of fins are perpendicular to the plane of the heat sink base and are positioned along the length of the heat sink base at a second acute angle with respect to the length of the heat sink base; and

a diversion fin centrally positioned along the length of the heat sink base between the first set of fins and the second set of fins, the diversion fin configured to divert the air convected through the air channels in the first set of fins and the second set of fins away from the heat sink base, the diversion fin having a first surface and a second surface opposing the first surface, wherein air convected through the air channels in the first set of fins is directed away from the heat sink base by the first surface and air convected through the air channels in the second set of fins is directed away from the heat sink base by the second surface.

2. The heat sink with angled fins of claim 1 , further comprising:

a solar shield having openings centrally positioned along a length of the solar shield, wherein the solar shield overlays and is offset from the first set of fins and second set of fins overlaying the heat sink base, wherein the directed convected air flows through the openings.

3. The heat sink with angled fins of claim 2 , further comprising:

solar shield standoffs operably positioned to hold the solar shield an offset distance from the first set of fins and the second set of fins.

4. The heat sink with angled fins of claim 1 , further comprising:

a first thermal interface layer to transfer heat, the first thermal interface layer operably positioned between the first set of fins and the heat sink base on a first side of the diversion fin; and

a second thermal interface layer to transfer heat, the second thermal interface layer operably positioned between the second set of fins and the heat sink base on a second side of the diversion fin.

5. The heat sink with angled fins of claim 1 , further comprising:

at least one fin clamping bar having indents and holes, each indent formed to fit around an end of a respective fin in one of the first set of fins and the second set of fins; and

fin clamping attachments to fit in the holes in the at least one fin clamping bar, wherein the at least one fin clamping bar fixedly attaches the first set of fins and the second set of fins to the heat sink base on the first side and the second side of the diversion fin, respectively, when the fin clamping attachments are fixed to the heat sink base through the holes in the at least one fin clamping bar.

6. A heat sink with angled fins, comprising:

a first set of fins forming air channels, the first set of fins including a plurality of first interlocking fin-sections;

a second set of fins forming air channels, the second set of fins including a plurality of second interlocking fin-sections, each interlocking fin-section having the shape of a parallelogram, and each interlocking fin-section comprising:

a male edge including a male interlocking feature; and

a female edge opposing and parallel to the male edge, the female edge including a female interlocking feature, the male edge and the female edge parallel to a length of the fins, the heat sink further comprising:

a heat sink base having a surface forming a plane coupled to the first set of fins and the second set of fins, wherein the first set of fins and the second set of fins are separated by a region along a length of the heat sink base, and wherein the fins in the first set of fins are perpendicular to the plane of the heat sink base and are positioned along the length of the heat sink base at a first acute angle with respect to the length of the heat sink base, and wherein the fins in the second set of fins are perpendicular to the plane of the heat sink base and are positioned along the length of the heat sink base at a second acute angle with respect to the length of the heat sink base.

7. A heat sink with angled fins comprising:

interlocking fin-sections comprising thermally conductive fins protruding from a thermally conductive fin base,

wherein a first set of interlocking fin-sections are operably attached to each other to form a first set of fins in which a first fin base has the shape of a first non-rectangular parallelogram, the fins of the first set of fins extending a length that is parallel to a shorter edge of the first non-rectangular parallelogram, and

wherein a second set of interlocking fin-sections are operably attached to each other to form a second set of fins in which a second fin base has the shape of a second non-rectangular parallelogram, the fins of the second set of fins extending a length that is parallel to a shorter edge of the second non-rectangular parallelogram;

a heat sink base coupled to the first set of fins and the second set of fins;

a diversion fin centrally positioned along a length of the heat sink base to segment the heat sink base into a first side and a second side, the first side operable to support the first set of fins and the second side operable to support the second set of fins, the diversion fin configured to divert air convected between the fins away from the heat sink base.

8. The heat sink with angled fins of claim 7 , the diversion fin further comprising:

a first surface; and

a second surface opposing the first surface, wherein air convected by the first set of fins is directed away from the heat sink base by the first surface and air convected by the second set of fins is directed away from the heat sink base by the second surface.

9. The heat sink with angled fins of claim 8 , further comprising:

a solar shield having openings centrally positioned along a length of the solar shield, wherein the solar shield overlays and is offset from the first and second set of fins overlaying the heat sink base, wherein the convected air directed away from the heat sink base by the diversion fin flows through the openings; and

solar shield standoffs operably positioned to hold the solar shield an offset distance from the first set of fins and the second set of fins.

10. The heat sink with angled fins of claim 7 , further comprising:

a first thermal interface layer operably positioned between the first set of fins and the first side of the heat sink base; and

a second thermal interface layer operably positioned between the second set of fins and the second side of the heat sink base.

11. The heat sink with angled fins of claim 7 , further comprising:

fin clamping bars having indents and holes, each indent formed to fit around an end of a respective fin in one of the first set of fins and the second set of fins; and

fin clamping attachments to fit in the holes in the fin clamping bars, wherein the fin clamping bars fixedly attach the first set of fins and the second set of fins to the first side and the second side, respectively, of the diversion fin in the heat sink base when the fin clamping attachments are fixed to the heat sink base through the holes in the fin clamping bars.

12. The heat sink with angled fins of claim 7 , wherein the interlocking fin-sections comprise a set of first interlocking fin-sections and a set of second interlocking fin-sections, each interlocking fin-section having the shape of a parallelogram, and each interlocking fin-section comprising:

a male edge including a male interlocking feature;

a female edge opposing and parallel to the male edge, the female edge including a female interlocking feature, the male edge and the female edge parallel to a length of the fins;

a first edge to receive input air in the air channels formed by neighboring fins; and

a second edge opposing and parallel to the first edge wherein output air emitted from the air channels is warmer than the input air.
