Abstract: A hybrid cooler has a first condenser block and a second condenser block. A liquid-cooled cold plate has opposed first and second external major surfaces and an internal passageway to direct a flow of coolant through the liquid-cooled cold plate to cool the opposed first and second external major surfaces. The internal passageway is fluidically coupled with the first condenser block and the second condenser block. The hybrid cooler has a first passive cold plate and a second passive cold plate, each extending from the first condenser block to the second condenser block. Each of the first passive cold plate and the second passive cold plate has a respective major surface positioned opposite the opposed first and second external major surfaces of the liquid-cooled cold plate. The liquid-cooled cold plate is positioned between the first passive cold plate and the second passive cold plate.

Abstract: 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.

Abstract: A fluid heat exchanger for cooling an electronic device can have a plurality of walls. The walls can define a corresponding plurality of microchannels. Each microchannel can extend from a first end to a second end. The plurality of microchannels can define at least two opposed outer microchannels and a centrally located microchannel positioned between the opposed outer microchannels. A fluid inlet passage can be configured to deliver a heat-exchange fluid to each microchannel between the corresponding first end and the corresponding second end of the respective microchannel. A fluid outlet passage can have an enlarged outlet region from the centrally located microchannel compared to a corresponding outlet region from one or both of the opposed outer microchannels. Related methods are disclosed.

Abstract: In some respects, concepts disclosed herein generally concern systems, methods and components to detect a presence of a liquid externally of a desired primary flow path through a segment of a fluid circuit, e.g., throughout a cooling loop. Some disclosed concepts pertain to systems, methods, and components to direct seepage or leakage of a liquid coolant toward a lead-detection sensor. As but one example, some disclosed liquid-cooled heat exchangers incorporate a leak-detection sensor, which, in turn, can couple with a computing environment that monitors for detected leaks, and, responsive to an indication of a detected leak, invokes a task to control or to mitigate the detected leak.

Abstract: A modular heat exchange assembly includes a cold plate defining a finned surface and a corresponding plurality of microchannels. Selected ones of the plurality of microchannel extend from a first end to an opposed second end. A fluid receiver unit defines an inlet port and a first fluid connector fluidically coupled with the inlet port. A fluid transfer unit defines an outlet port and a second fluid connector matingly engageable with and disengageable from the first fluid connector to fluidly couple the fluid receiver unit and the fluid transfer unit together. The fluid transfer unit defines a distribution manifold configured to distribute coolant among the selected microchannels at a position between the first ends and the second ends of the selected microchannels. The fluid transfer unit further defines a collection manifold configured to receive coolant from the selected microchannels. The collection manifold and the outlet port are fluidically coupled together.

Abstract: An observed operational state can include an operational state of one or more system devices. A sensor can emit, in response to a detected observable condition reflective of a given operational state, a simulated signal reflective of a different operational state as a proxy for the detected condition. A controller receiving such a proxy signal can, at least partially responsively to the proxy signal, issue a command corresponding to the given operational state. An electro-mechanical actuator can be selectively activatable responsive to the command.

Abstract: An observed operational state can include an operational state of one or more system devices. A sensor can emit, in response to a detected observable condition reflective of a given operational state, a simulated signal reflective of a different operational state as a proxy for the detected condition. A controller receiving such a proxy signal can, at least partially responsively to the proxy signal, issue a command corresponding to the given operational state. For example, a leak detector can emit in response to a detected leak, or a flow-rate sensor can emit in response to a detected flow-rate of a liquid, a simulated fan-speed tachometer signal representative of a selected fan speed. At least partially in response to observing a simulated tachometer signal, a controller can issue a system command corresponding to an underlying system condition for which the simulated tachometer signal is a proxy.

Abstract: A fluid heat exchanger includes: a heat spreader plate including an intended heat generating component contact region; a plurality of microchannels for directing heat transfer fluid over the heat spreader plate, the plurality of microchannels each having a first end and an opposite end and each of the plurality of microchannels extending substantially parallel with each other microchannel and each of the plurality of microchannels having a continuous channel flow path between their first end and their opposite end; a fluid inlet opening for the plurality of microchannels and positioned between the microchannel first and opposite ends, a first fluid outlet opening from the plurality of microchannels at each of the microchannel first ends; and an opposite fluid outlet opening from the plurality of microchannels at each of the microchannel opposite ends, the fluid inlet opening and the first and opposite fluid outlet openings providing that any flow of heat transfer fluid that passes into the plurality of microchannels, flows along the full length of each of the plurality of microchannels in two directions outwardly from the fluid inlet opening. A method of cooling a heat generating component uses a fluid heat exchanger that splits a mass flow of coolant.
