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 counterflow heat exchanger configured to exchange thermal energy between a first fluid flow at a first pressure and a second fluid flow at a second pressure less than the first pressure 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. A heating arrangement is configured to heat the second fluid inlet to prevent ice ingestion via the second fluid inlet.

Abstract:
An exemplary cooling system includes a heat transfer device having a base and a plurality of curved fins defining a curved air flow channel. Air flow is provided through the air flow channel, and a plurality of openings through a fin communicate air flow from a first side to a second side of the curved fin.
Abstract:
An on-board aircraft dried inert gas system includes a source inert gas containing water, an air cycle or vapor cycle cooling system, and a heat exchanger condenser. The heat exchanger condenser has a heat absorption side in thermal communication with the air cycle or vapor cycle cooling system. The heat exchanger condenser has a heat rejection side that receives the inert gas containing water and outputs dried inert gas.

Abstract:
A method and apparatus for exchanging heat between two fluids is disclosed. The apparatus includes an integrated blower with a diffuser fin baseplate. The baseplate includes diffuser fins on a surface of the baseplate. The diffuser fins are integrated with the blower. At least one channel is formed in the fins or baseplate for flow of a fluid through the baseplate.
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.
