Classification: CPC F  H | IPC F  H

Claim 9:
10. A redundant apparatus for cooling a heat source, the redundant apparatus comprising:
a thermally conductive base member configured to be placed in thermal communication with the heat source, the thermally conductive base member comprising a surface to be cooled; and
a redundant heat sink module mounted on the thermally conductive base member, the redundant heat sink module comprising:
a first independent coolant pathway formed within the redundant heat sink module, the first independent coolant pathway comprising: a first inlet chamber; a first outlet chamber; and a first plurality of orifices configured to provide a first plurality of impinging jet streams of coolant against a first region of the surface to be cooled when pressurized coolant is provided to the first inlet chamber; and
a second independent coolant pathway formed within the redundant heat sink module, the second independent coolant pathway comprising: a second inlet chamber fluidly connected to a second outlet chamber, the second outlet chamber bounded by a second region of the surface to be cooled; and
one or more sealing members disposed between a bottom surface of the redundant heat sink module and a surface of the thermally conductive base member to provide a first liquid-tight seal around a perimeter of the first outlet chamber and a second liquid-tight seal around a perimeter of the second outlet chamber,

wherein the second region of the surface to be cooled circumscribes the first region of the surface to be cooled.
