Heat exchanger assemblies for electronic devices and related methods are disclosed. A heat exchanger assembly may include a heat transfer body that has a face that forms open passageways, and a cover structure attached to the heat transfer body that encloses the open passageways, thereby forming enclosed fluid conduits. Heat exchanger assemblies as described herein may be thermally coupled to a center waveguide section of a spatial power-combining device. Related methods include forming open passageways by selectively removing material from a face of a heat transfer body. Multiple heat transfer bodies may be formed simultaneously by forming multiple groups or patterns of open passageways across a larger area of a heat transfer body material, and subsequently singulating the heat transfer body material into multiple heat transfer bodies. Cover structures as previously described may be formed on the heat transfer bodies before or after singulation.

The present disclosure provides an air handler having a cabinet and a plurality of refrigerant tubes, where each refrigerant tube has a diameter of 7 mm. The air handler includes a V-shaped round tube plate fin heat exchanger disposed within the cabinet and including a plurality of louvered fins. Each louvered fin defines a plurality of holes configured to receive the refrigerant tubes. The plurality of holes defines a linear offset configuration of the louvered fin. The air handler further includes an axial fan housing disposed within the cabinet and located downstream of the V-shaped round tube plate fin heat exchanger, a distributor in fluid communication with the refrigerant tubes, and a plurality of feeder tubes extending between the distributor and the refrigerant tubes. Each feeder tube is configured to allow flow of refrigerant therethrough.

In a tank structure of a heat exchanger having a narrow width header plate, to reduce thermal stress generated in a tube on the outermost side of the header plate in a lengthwise direction. Insertion holes, except for end-portion tube insertion holes at least located at end portions of a header plate in the lengthwise direction, are linked with deformation prevention beads formed along the lengthwise direction of the header plate, and the end-portion tube insertion holes are not linked with the deformation prevention beads.

The present invention relates to a V-shaped heat exchanger for condensing exhaust steam from a turbine. The V-shaped heat exchanger comprises primary, secondary and tertiary single-row condensing tubes placed in a V-shaped geometry. A steam supply manifold supplies the exhaust steam to lower ends of the primary tubes and steam that is not condensed in the primary tubes is collected at upper ends of the primary tubes and transported to the secondary tubes using top connecting manifolds. Steam that is not condensed in the secondary tubes is further transported to the tertiary tubes using a bottom connection manifold. The tertiary tubes are coupled at their ends with an evacuation manifold for evacuating non-condensable gases.

The invention relates to a heat exchanger assembly with at least one multi-pass heat exchanger, comprising a first distributor (1) with a first connection part (1a) for connecting to a fluid line (9), a second distributor (2) with a second connection part (2a) for connecting to a fluid line (9), and at least one first deflection distributor (4), as well as a plurality of tube lines (5) through which a fluid, in particular water, can flow, wherein the first distributor (1) and the second distributor (2) are arranged at one end (A) of the heat exchanger assembly, the deflection distributor (4) is arranged at the opposite end (B) and the tube lines (5) extend from the one end (A) to the opposite end (B), and wherein the first connection part (1a) is arranged at a lowest point (T) or at least near to the lowest point (T) of the first distributor (1) and the second connection piece (2a) is arranged at a lowest point (T) or at least near to the lowest point (T) of the second distributor (2).
