Abstract
A heat sink assembly and a method of utilizing a heat sink assembly where the heat sink assembly is configured to dissipate air from the bottom of the heat sink assembly to the top of the heat sink assembly utilizing a plurality of vents to cool a desired electrical component.
Claims18
A heat sink assembly, comprising:
- a first heat sink having a top portion, a bottom portion, and a plurality of fins extending between the top portion and the bottom portion, the bottom portion having at least one tooth depression to receive air, the first heat sink having at least one fastener terminal to receive a fastener;
- a second heat sink having a top portion, a bottom portion, and a plurality of fins extending between the top portion and the bottom portion, the second heat sink having at least one fastener configured to engage the at least one fastener terminal of the first heat sink;
- a casing disposed over the first heat sink and the second heat sink, the casing having a top portion and a bottom portion, the bottom portion having at least one vent to receive air and the top portion having at least one vent to release air;
- wherein air is received through at least one of the at least one tooth of the first heat sink or the at least one vent of the bottom portion of the casing and wherein air flows upwardly through the plurality of fins of the first heat sink and second heat sink and heat is absorbed by the plurality of fins, wherein the air flows to the top portion of the casing and through the at least one vent of the casing to release air to cool a desired electrical component, and at least one thermal pad disposed between at least one of printed circuit board (PCB board) and the first heat sink or the PCB board and the second heat sink for absorb heat as air passes through the plurality of fins of the first heat sink and the second heat sink.

- a heat sink having a top portion, a bottom portion, and a plurality of fins extending upwardly between the top portion and the bottom portion, the bottom portion having at least one tooth depression to receive air;
- a casing disposed over the heat sink, the casing having a top portion and a bottom portion, the bottom portion having at least one vent to receive air and the top portion having at least one vent to release air;
- wherein air is received through at least one of the at least one tooth of the heat sink or the at least one vent off the bottom portion of the casing and wherein air flows upwardly through the plurality of fins of the heat sink and heat is absorbed by the plurality of fins and wherein the air flows to the top portion of the casing and through the at least one vent to release air to cool a desired electrical component.
A method of utilizing a heat sink assembly, comprising:
- providing a first heat sink having a top portion, a bottom portion, at least one lock catch to receive a lock, and a plurality of fins extending between the top portion and the bottom portion, the bottom portion having at least one tooth depression to receive air;
- providing a casing disposed over the first heat sink, the casing having a top portion and a bottom portion, the bottom portion having at least one vent to receive air and the top portion having at least one vent to release air;
- wherein the first heat sink assembly is configured to receive air through one of the at least one vent of the bottom portion of the casing and the at least one tooth of the bottom portion of the first heat sink, and wherein air flows upwardly through the plurality of fins of the heat sink to the top portion of the casing and through the at least one vent of the casing to cool a desired electrical component;
- and
- a second heat sink having at least one lock for affixing the second heat sink to the first heat sink.
