In at least one embodiment, an output of processor used with an intelligent in-rack pump or compressor unit may be adapted to provide signals to cause one or more flow controllers to be adjusted in a first mode so that two-phase fluid flow occurs in a first mode, different than secondary coolant flow that occurs in a second mode. In at least one embodiment, two-phase fluid flow may be increased or decreased to a heat exchanger depending on which mode is active.
In at least one embodiment, an input of a processor used with an intelligent in-rack pump or compressor unit is adapted to receive sensor inputs associated with a temperature from at least one computing device, from secondary coolant, or from two-phase fluid exiting a cold plate. In at least one embodiment, one or more neural networks of a processor may be trained to infer that a change in coolant state has occurred based in part on a temperature and on prior temperatures of at least one computing device, secondary coolant, or two-phase fluid. In at least one embodiment, one or more circuits of a processor may be adapted to cause a first mode or a second mode of operation for a datacenter cooling system.
