Abstract
A heat sink includes a base having a structure side and an opposite environmental side. The structure side of the base is configured to thermally communicate with a structure for absorbing heat from the structure. A cooling fin extends a height outwardly from the environmental side of the base. The cooling fin extends a cord length along the base from a leading edge to a trailing edge of the cooling fin. The cooling fin includes the cross-sectional shape of an airfoil along at least a portion of the height of the cooling fin to increase the velocity of a flow of air along the cord length of the cooling fin.
Claims20
A heat sink comprising:
- a base having a structure side and an opposite environmental side, the structure side of the base being configured to thermally communicate with a structure for absorbing heat from the structure;
- and
- a cooling fin extending a height outwardly from the environmental side of the base, the cooling fin extending a cord length along the base from a leading edge to a trailing edge of the cooling fin, the cooling fin comprising the cross-sectional shape of an airfoil along at least a portion of the height of the cooling fin to increase the velocity of a flow of air along the cord length of the cooling fin.
A receptacle assembly for a pluggable module, said receptacle assembly comprising:
- a receptacle configured to receive the pluggable module therein;
- and
- a heat sink mounted to the receptacle, the heat sink comprising:
- a base having a structure side and an opposite environmental side, the structure side of the base being configured to thermally communicate with a structure for absorbing heat from the structure;
- and
- a cooling fin extending a height outwardly from the environmental side of the base, the cooling fin extending a cord length along the base from a leading edge to a trailing edge of the cooling fin, the cooling fin comprising the cross-sectional shape of an airfoil along at least a portion of the height of the cooling fin to increase the velocity of a flow of air along the cord length of the cooling fin.
A heat sink comprising:
- a base having a structure side and an opposite environmental side, the structure side of the base being configured to thermally communicate with a structure for absorbing heat from the structure;
- a first cooling fin extending a height outwardly from the environmental side of the base, the first cooling fin comprising the cross-sectional shape of an airfoil along at least a portion of the height of the first cooling fin;
- a second cooling fin extending a height outwardly from the environmental side of the base;
- a fluid channel defined between the first and second cooling fins, the environmental side of the base defining a lower boundary of the fluid channel;
- and
- a cap defining an upper boundary of the fluid channel, wherein the cap comprises the cross-sectional shape of an airfoil.
