Patent ID: 7466551

Claim:
A variable thermal dissipation apparatus comprising: a first chassis and a second chassis, wherein the first chassis defines a first internal height and the second chassis defines a second internal height that is greater than the first internal height; a plurality of first heat sinks, wherein each of the first heat sinks are sized to allow the first heat sink to be positioned within the first internal height defined by the first chassis and within the second internal height defined by the second chassis; a second heat sink, wherein the second heat sink is sized to allow the combination of the second heat sink mounted to the first heat sink to be positioned within the second internal height defined by the second chassis but not positioned within the first internal height defined by the first chassis; at least one of the first heat sinks mounted on each of a heat producing component that is located in the first chassis and a heat producing component that is located in the second chassis; and the second heat sink being mounted on the first heat sink that is mounted on the heat producing component located in the second chassis.
