摘要: Methods and apparatus for an autonomous stage-switching multi-stage cooling device are disclosed are disclosed. A disclosed example coolant distribution unit (CDU) includes an enclosure, an inlet and an outlet of the CDU to be fluidly coupled to a cooling block associated with a heat generating source, at least one sensor to measure a first temperature corresponding to the inlet and a second temperature corresponding to the outlet, and a plurality of valves to be controlled by a controller to control a flow of fluid from the inlet to at least one of an ambient cooler or a sub-ambient cooler based on: (i) a comparison of the first temperature to an ambient temperature and (ii) a comparison of the second temperature to a target temperature.
