1. An apparatus comprising:

  • a composite heat sink structure including;

    a thermally conductive base, the thermally conductive base including a main heat transfer surface to couple to at least one component to be cooled;

    a compressible, continuous sealing member;

    a sealing member retainer compressing the compressible, continuous sealing member against the thermally conductive base;

    an in situ molded member molded over and affixed to the thermally conductive base, and molded over and securing in place the sealing member retainer, wherein a coolant-carrying compartment resides between the thermally conductive base and the in situ molded member and wherein the in situ molded member is a unitary member that contacts a surface of the thermally conductive base opposite to the main heat transfer surface and wraps around at least a portion of the thermally conductive base to secure the in situ molded member to the thermally conductive base absent use of separate fasteners; and

    a coolant inlet and a coolant outlet, the coolant inlet and coolant outlet being in fluid communication with the coolant-carrying compartment to facilitate liquid coolant flow therethrough.
