In one exemplary embodiment of the present invention, a heat sink having an embedded heat pipe and fins attached to opposite sides of the base plate. In an alternative embodiment, the base plate includes a main heat pipe and auxiliary heat pipes coupled to the main heat pipe. The fins are aligned with the auxiliary heat pipes.
1. A heat sink, comprising:
a main heat pipe;
a plurality of auxiliary heat pipes coupled to said main heat pipe;
a wrap-around plate that covers said main heat pipe and said plurality of auxiliary heat pipes; and
a plurality of fins coupled to opposite sides of said wrap-around plate and aligned with said plurality of auxiliary heat pipes, wherein pairs of auxiliary heat pipes disposed near opposite sides of said wrap-around plate are aligned along a length of said main heat pipe.
2. A heat sink, comprising:
a main heat pipe;
a plurality of auxiliary heat pipes coupled to said main heat pipe;
a wrap-around plate that covers said main heat pipe and said plurality of auxiliary heat pipes; and
a plurality of fins coupled to opposite sides of said wrap-around plate and aligned with said plurality of auxiliary heat pipes, wherein pairs of auxiliary heat pipes disposed near opposite sides of said wrap-around plate are aligned along a length of said main heat pipe, and wherein each auxiliary heat pipe has a diameter that is less than a diameter of said main heat pipe.
3. A heat sink, comprising:
a main heat pipe;
a plurality of auxiliary heat pipes coupled to said main heat pipe;
a wrap-around plate that covers said main heat pipe and said plurality of auxiliary heat pipes; and
a plurality of fins coupled to opposite sides of said wrap-around plate and aligned with said plurality of auxiliary heat pipes, wherein pairs of auxiliary heat pipes disposed near opposite sides of said wrap-around plate are aligned along a length of said main heat pipe, and wherein each fin is aligned with each auxiliary heat pipe along a flow length.
4. A heat sink, comprising:
a main heat pipe;
a plurality of auxiliary heat pipes coupled to said main heat pipe;
a wrap-around plate that covers said main heat pipe and said plurality of auxiliary heat pipes; and
a plurality of fins coupled to opposite sides of said wrap-around plate and aligned with said plurality of auxiliary heat pipes, wherein pairs of auxiliary heat pipes disposed near opposite sides of said wrap-around plate are aligned along a length of said main heat pipe and each auxiliary heat pipe has a diameter that is less than a diameter of said main heat pipe, and wherein each auxiliary heat pipe has an end portion that wraps partially around said main heat pipe.
