A heat exchanger for use in a gas turbine engine has a central body including an inlet manifold and at least one tube providing an outlet manifold, and a plurality of tubes communicating holes in an outer periphery of the inlet manifold to holes in an outer periphery of the outlet manifold, and passages for cooling air to pass across the tubes. A gas turbine engine is also disclosed.

A refrigerant diverter diverts inflowing refrigerant and to cause the refrigerant to flow out to a downstream side. The refrigerant diverter includes a vertically extending diverter case, and a vertically extending rod-shaped rod member disposed inside the diverter case. The diverter case has a plurality of diverting channels disposed along a circumferential direction, a diverting space arranged to guide the refrigerant to the diverting channels, and a plurality of expelling spaces that communicate with the diverting space through the diverting channels, the expelling spaces being disposed along a vertical direction. The diverting channels are configured from a plurality of holes extending in a longitudinal direction of the rod member and integrally formed in the rod member.

An arrangement for storing thermal energy has at least two tunnels (1a, 1b) for holding a fluid. The tunnels (1a, 1b) are connected to each other by at least one channel (2), such that fluid communication is allowed between the tunnels (1a, 1b). Each of the inner tunnel (1a) and the outer tunnel (1b) is configured as a helix, the inner tunnel (1a) forming an inner helix and the outer tunnel (1b) forming an outer helix.

A heat exchanger is configured such that flat tubes in at least two levels bent or connected to each other at one end in an axial direction of the flat tubes and the flat tubes in at least two columns connected to each other are included in refrigerant passages through which refrigerant flows, and a flow direction of gas is counter to flow of refrigerant through the refrigerant passages in a column direction while the heat exchanger serves as a condenser.

An appliance includes a compact condenser assembly formed with at least two separately and independently produced wire on tube condensers. Each of the at least two wire on tube condensers has a condenser inlet and a condenser outlet. The at least two wire on tube condensers are at least substantially locked and positioned in a matingly engaged configuration forming a compact condenser assembly. The at least two wire on tube condensers are configured to be operationally connected in at least one of a parallel configuration, a series configuration, a selectable configuration, and a bypass configuration.

A heat exchanger includes a plurality of flat tubes, a header part, and a guide part. An interior of the header part is partitioned into first and second spaces. One end of each of the tubes is connected to the first space. The guide part has a guide space positioned below the first space. The guide space communicates with the first space via an ascending opening. The first and second spaces communicate with each other via upper and lower communication ports provided within upper and lower sides of the header part, respectively. When the heat exchanger is viewed from above after installation, the tubes and the ascending opening have an area of overlap, and the ascending opening and a space where the lower communication port is extended do not overlap or have an area of overlap that is up to 50% of the ascending opening.

An electric machine. The electric machine includes one or more face wound strips including a first strip. The one or more strips have a plurality of openings. The first strip has a plurality of turns, and an opening of a turn of the first strip overlaps an opening of an adjacent turn, to form a portion of a fluid channel of a plurality of fluid channels. The turn and the adjacent turn abut against each other at the overlapping openings.

A radiator includes a tube that has a flattened-shape, the tube including an internal flow channel that allows a coolant to flow through the internal flow channel; and a tank that includes an insertion port into which a joint end portion of the tube is inserted so that the tank and the tube are joined to each other, wherein the tube includes an outer-peripheral-wall extending in a direction perpendicular to a thickness direction of the tube, and bend depressions that are bent toward the internal flow channel in a concave shape are formed in at least a region of the outer-peripheral-wall adjacent to the joint end portion, the bend depressions extending along the internal flow channel, and the bend depressions are deformed in a width direction of the tube so that the width of the joint end portion is the same as the width of the insertion port.

A method and a system for a heat exchanger assembly are provided. The heat exchanger assembly includes one or more arcuate heat exchanger segments each including an inlet header configured to extend circumferentially about a circumference of an inner surface of a fluid flow duct, and an outlet header configured to extend circumferentially about the fluid flow duct. The heat exchanger assembly also includes a first serpentine heat exchanger tube extending between the inlet header and the outlet header and including a series of flow path segments having a gradually changing direction defined by a bend radius of the tube such that a direction of flow through the serpentine heat exchanger tube reverses between the inlet and the outlet headers and a second serpentine heat exchanger tube extending between the inlet header and the outlet header, the second serpentine heat exchanger tube co-planar with the first serpentine heat exchanger tube.

The embodiments described herein are directed to a coil support and a method of using the coil support for condensate management. The coil support generally functions to provide support for evaporator and/or condenser coils and facilitate the drainage of condensate away from coil headers.
