Abstract: A heat exchanger includes a body shaped to integrate with one or more system structural elements and a plurality of first flow channels defined in the body. The heat exchanger also includes a plurality of second flow channels defined in the body. The second flow channels are fluidly isolated from the first flow channels. The first flow channels and the second flow channels have a changing flow direction characteristic along a direction of flow within the first flow channels and the second flow channels.

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 counterflow heat exchanger configured to exchange heat between a first fluid flow at a first pressure and a second fluid flow at a second 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. 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. Each first fluid passage of the plurality of first fluid passages has a circular cross-section.

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.
