A heat-transfer system includes a cooling circuit configured to convey heated coolant from one or more cooling nodes to one or more heat-rejection devices, and to convey the cooled coolant from the one or more heat-rejection devices to the one or more cooling nodes. Each cooling node facilitates a transfer of heat to the coolant, the heat being from one or more heat-dissipation devices and a corresponding heat load on the respective cooling node. Each heat-rejection device facilitates heat transfer from the coolant to another medium. The heat-transfer system also has a selectively operable flow-control device configured to control a flow rate of the coolant through a segment of the coolant circuit. A control logic selectively operates the flow-control device responsive to an output from one or more sensors to tailor a cooling capacity available to each cooling node to the real-time heat load on the respective cooling node.

Smart components, systems and methods for transferring heat

A pump tray has a liquid pump with an inlet and outlet. A blindly matable liquid coupler fluidicly couples with the pump inlet and a blindly matable liquid coupler fluidicly couples with the pump outlet. A chassis of the pump tray has an alignment member configured to removably engage with another device and to restrict, to a limited number of degrees-of-freedom, movement of the chassis relative to the other device (e.g., a liquid pumping unit). The blindly matable liquid couplers are so physically coupled with the chassis as to inhibit movement of them relative to the chassis. A liquid pumping unit also has a chassis defining a bay configured to receive a pump tray, a liquid inlet coupler and a liquid outlet coupler, and a reservoir fluidicly coupled with the liquid inlet coupler. A blindly-matable liquid coupler fluidicly couples with the reservoir outlet and a blindly-matable liquid coupler fluidicly couples with the liquid outlet coupler. An alignment member is configured to removably engage with the pump tray and to restrict, to a limited number of degrees-of-freedom, movement of the pump tray relative to the chassis of the liquid pumping unit.

Active two-phase cooling systems incorporate a cooling medium that changes phase as it absorbs heat dissipated by a heat source and a pump or a compressor that urges the cooling medium through a cooling loop. Operation of some heat sources, e.g., electronic devices, can improve if maintained at a substantially uniform operating temperature. A cooling medium can enter a node for cooling such a heat source at or near a saturation state and can exhaust from the node as a saturated mixture, providing a substantially uniform temperature across the node while taking advantage of the cooling medium's relatively high latent-heat of phase-change to provide a high rate of cooling to the heat source. Although counterintuitive, a cooling loop can pre-heat a sub-cooled flow of the cooling medium to provide the medium to the node in a saturated state. Such pre-heating can be achieved by the saturated mixture of the cooling medium after exhausting from the node.
