Abstract: A multi-chamber heat sink module can provide fluid cooling of one or more heat providing surfaces. The module can include a first plurality of orifices fluidly connecting a first inlet chamber to a first outlet chamber. The first outlet chamber can be configured to be bounded by a portion of a heat providing surface. The first plurality of orifices can be configured to deliver a first plurality of jet streams of coolant into the first outlet chamber and against the 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. The heat sink module can include a second inlet chamber fluidly connected to a first outlet passage and a second plurality of orifices fluidly connecting the second inlet chamber to a second outlet chamber.
