Multi-chamber heat sink module

A multi-chamber heat sink module for cooling one or more heat providing surfaces, the heat sink module comprising:

• a first plurality of orifices fluidly connecting a first inlet chamber to a first outlet chamber;
• and a first outlet passage fluidly connected to the first outlet chamber, the first outlet chamber configured to be bounded by a first portion of a heat providing surface when the heat sink module is installed on the heat providing surface, the first plurality of orifices configured to deliver a first plurality of jet streams of coolant into the first outlet chamber and against the first portion of the heat providing surface when the heat sink module is installed on the heat providing surface and when pressurized coolant is provided to the first inlet chamber;
• and
• a second inlet chamber fluidly connected to the first outlet passage;
• and a second plurality of orifices fluidly connecting the second inlet chamber to a second outlet chamber, the second outlet chamber configured to be bounded by a second portion of the heat providing surface when the heat sink module is installed on the heat providing surface, the second plurality of orifices configured to deliver a second plurality of jet streams of coolant into the second outlet chamber and against the second portion of the heat providing surface when the heat sink module is installed on the heat providing surface and when pressurized coolant is provided to the second inlet chamber.

A multi-chamber heat sink module for cooling one or more heat providing surfaces, the heat sink module comprising:

• a thermally conductive base member comprising a first surface and a second surface opposite the first surface, the second surface adapted to be placed in thermal communication with a heat source;
• a first plurality of orifices fluidly connecting a first inlet chamber to a first outlet chamber;
• and a first outlet passage fluidly connected to the first outlet chamber, the first outlet chamber bounded by a first portion of the first surface of the thermally conductive base member when the heat sink module is installed on the first surface of the thermally conductive base member, the first plurality of orifices configured to deliver a first plurality of jet streams of coolant into the first outlet chamber and against the first portion of the first surface of the thermally conductive base member when pressurized coolant is provided to the first inlet chamber;
• and
• a second inlet chamber fluidly connected to the first outlet passage;
• and a second plurality of orifices fluidly connecting the second inlet chamber to a second outlet chamber, the second outlet chamber bounded by a second portion of the first surface of the thermally conductive base member, the second plurality of orifices configured to deliver a second plurality of jet streams of coolant into the second outlet chamber and against the first portion of the first surface of the thermally conductive base member when pressurized coolant is provided to the second inlet chamber.
