Abstract: At least one cooling channel is positioned adjacent to an electronic component. The cooling channel communicates with plenums at each of two opposed axial ends. A dielectric fluid is received in the cooling channel. The cooling channel is provided with at least one electrode. A potential is applied to the at least one electrode such that an electric field magnitude at the downstream end of the channel is less than an upstream electric field magnitude, and such that a dielectrophoretic force on a bubble in the cooling channel will force it downstream.

Abstract: A heat exchanger includes a plate with an external surface, a channel, and a nozzle. The external surface bounds an interior of the plate. The channel is disposed in the heat exchanger and passes through a portion of the interior. The nozzle is integrally disposed in the heat exchanger, extends through a portion of the external surface, and is fluidly connected to the channel. The nozzle is configured to transport a liquid from the channel, through the external surface, and to distribute the liquid onto a portion of the heat exchanger.

Abstract: A refrigeration circuit includes a primary loop, a secondary loop connected to the primary loop, a first expansion valve connected to the secondary loop, and a second expansion valve. The second expansion valve is connected to the secondary loop and is in parallel with the first expansion valve to control thermal communication between the refrigeration circuit and a first heat load independent of thermal communication between the refrigeration circuit and a second heat load. Environmental control systems and methods of controlling refrigerant flow in refrigeration circuits are also described.

Abstract: A method of cooling a component with a heat exchange device includes pulling air into a central airway in a heat exchange device using a blower; directing the air from the blower through a diffuser and across a heat sink base, wherein a first component positioned underneath the heat sink base is cooled when the air passes over the heat sink base; and directing the air out from the diffuser and across a second component to cool the second component.

Abstract: A counterflow heat exchanger includes a first fluid inlet, a first fluid outlet fluidly coupled to the first fluid inlet via a core section, a second fluid inlet, and a second fluid outlet fluidly coupled to the second fluid inlet via the core section. The core section includes a plurality of first fluid passages configured to convey the first fluid flow from the first fluid inlet toward the first fluid outlet, and a plurality of second fluid passages configured to convey the second fluid flow from the second fluid inlet toward the second fluid outlet such that the first fluid flow exchanges thermal energy with the second fluid flow at the core section. One or more drains are operably connected to the plurality of first fluid passages configured to remove condensation from an interior of the first fluid passages prior to the condensation reaching the first fluid outlet.
