A membrane heat exchanger comprising a first planar sheet and a second planar sheet coupled to the first planar sheet to form at least one fluid chamber defined by the first and second sheets and a first and second end that respectively communicate with a first and second port defined by at least one of the first and second sheet.

A radiant cooling device comprises at least one fluidic layer including one or more micro-channel liquid-circuits and at least one structural layer coupled to the at least one fluidic layer. The device further includes a plurality of folds such that the device has a three-dimensional surface geometry having a plurality of inclined surfaces.

A counter-flow plate type exchanger is manufactured by repeatedly folding and joining at least two strips of membrane to form a counter-pleated core with a stack of openings or fluid passageways configured in an alternating counter-flow arrangement. Methods for manufacturing such counter-pleated cores are described. Counter-pleated cores comprising water-permeable membranes can be used in a variety of applications, including heat and water vapor exchangers. In particular, they can be incorporated into energy recovery ventilators (ERVs) for exchanging heat and water vapor between air streams directed into and out of buildings, automobiles, or other Industrial processes.

Embodiments of the present disclosure include an air handling module. The air handling module may comprise an exchanger within a housing, a first manifold positioned on a first side of the housing and including a first pair of ports on a first end and a second pair of ports on a second end, and a second manifold positioned on a second side of the housing and including a first pair of ports on a first end and a second pair of ports on a second end. The first pairs of ports may be in fluid communication to transfer air through the exchanger and between the first and second manifolds, and the second pairs of ports may be in fluid communication to transfer air through the exchanger and between the first and second manifolds.

A collapsible heat exchanger comprising a first sheet; a second sheet on an opposing side of the collapsible heat exchanger from the first sheet; a first expansion element coupled to and extending between the first and second sheets; a second expansion element coupled to and extending between the first and second sheets; a manifold including a plurality of channels defined by at least one of a plurality of internal sidewalls; and a heat exchanger cavity defined at least by the plurality of channels and a first and second fluid conduit.

Devices, systems, and methods for a heat exchanger and operation of a heat exchanger are disclosed. The heat exchanger comprises a chamber with a plurality of fluid inlets and a plurality of fluid outlets. The chamber comprises plates, the plates being parallel and defining fluid plenums between each of the plates. The fluid plenums define a fluid flow path, wherein each of the fluid plenums are aligned with one of the plurality of fluid inlets, one of the plurality of fluid outlets, a fluid path between at least two of the fluid plenums, or a combination thereof. The plates are mounted on guides perpendicular to a plane of the plates. The plates move along the guides due to changes in pressure in the fluid plenums, application of an external force to the one or more plates, or a combination thereof.

A heat sink structure is provided having fins mechanically altered dynamically to change and optimize the heat sink's performance based on certain environmental conditions. Specifically, the shape of fins of the heat sink structure is dynamically altered in response to environmental conditions that indicate the need for increased thermal performance by spreading the fins through a mechanical device dynamically, or by collapsing the fins to reduce pressure drop across a region when increased thermal performance is not needed.

A membrane assembly includes a membrane film, and a plurality of tensile support members. The membrane film is configured to transfer heat and moisture between a liquid and air flowing through a LAMEE. The tensile support members are connected to the membrane or a substrate connected to the membrane. And, the tensile support members are in spaced relation to 5 one another and oriented perpendicular to a direction of flow of liquid through the LAMEE.
