An additively-manufactured heat exchanger header defines a build plane and a vertical axis defining a build direction that is orthogonal to the build plane. The additively-manufactured heat exchanger header includes a header body that at least partially contains a working fluid, and an upper support structure on the header body. The upper support structure defines an interior edge and includes a branchwork of gussets rising upward and outward from a root point located in the middle region on the header body. The header body defines a middle region, an upper region, and a top extension. The branchwork of gussets forms a number of top vanes, each supporting the top extension. The upper region is oriented over the middle region relative to the vertical axis, and the top extension partially defines the fluid boundary and is oriented over the upper region.

A heat exchanger includes: flat pipes each including a passage for refrigerant that are arranged side by side in a predetermined step direction; and a header collecting pipe extending along the predetermined step direction that is connected to the flat pipes. The header collecting pipe includes: a flat pipe-side header forming member; and an opposite-side header forming member facing the flat pipe-side header forming member. The flat pipes are inserted in the flat pipe-side header forming member and an internal space exists between the flat pipe-side header forming member and the opposite-side header forming member. When viewed along the predetermined step direction: the flat pipe-side header forming member has a flat pipe-side curved portion protruding toward the flat pipes and the opposite-side header forming member has an opposite-side curved portion protruding toward a side away from the flat pipes.

The present disclosure relates to a heat exchanger that is characterized by including at least one collector and at least one tube, in which case the tube is installed in the collector by at least one seal disposed between the collector and the tube in such a manner that fluid connection is possible between the collector and the tube, wherein the tube includes at least one reinforcing element. The present disclosure also relates to a method of installing a heat exchanger and a method of manufacturing a heat exchanger, in which case at least one tube is installed in at least one collector by at least one seal disposed between the collector and the tube in such a manner that fluid connection is possible between the collector and the tube, wherein at least one reinforcing element is provided in or to the at least one tube.

An air-conditioning unit includes an air-conditioning case and a heat exchanger. The heat exchanger includes a plurality of tubes and a header tank. The air-conditioning case includes a holder in which the header tank is held while being inserted therein. The holder includes a first rib and a plurality of second ribs for pressing a tank outer wall of the header tank toward an internal space of the header tank. The first rib extends in a tube stacking direction. The plurality of second ribs are each connected to the first rib, are formed to extend from the first rib away from the tubes, and are arranged side by side at a predetermined inter-rib spacing in the tube stacking direction. The inter-rib spacing is larger than a length of the second ribs extending from the first rib away from the tubes in a tube longitudinal direction.

A heat exchanger includes a header, a plurality of tubes, and a reinforcement member. The header has a face plate that defines a plurality of orifices, a top plate that extends away from an end of the face plate, and a projection that extends outward from the top plate. Each of the plurality of tubes extend into a respective one of the plurality of orifices. The reinforcement member has a backing plate that is secured to the top plate, a brace that extends from the backing plate and is secured to a first of the plurality of tubes, and a protrusion that extends outward from the backing plate. The protrusion engages the projection to restrict movement of the reinforcement member in a longitudinal direction relative to the tubes.

The invention concerns a header (4) for a heat exchanger adapted to have a refrigerant fluid (FR) passed through it and comprising a wall (4a-4d) delimiting a chamber (6) accommodating a device (7) for distribution of the refrigerant fluid (FR) inside the chamber (6), the distribution device (7) comprising at least one conduit (8a, 8b) extending between two ends (20a, 20b; 29a, 29b) along a longitudinal axis (A1), at least a first end (20a) of the conduit (8a) being provided with an inlet opening (10) for the admission of the refrigerant fluid (FR) to the interior of the distribution device (7), the distribution device (7) being provided with at least one orifice (11) oriented transversely to the longitudinal axis (A1) for the evacuation of the refrigerant fluid (FR) from the distribution device (7) to the chamber (6), characterized in that it comprises at least one member (17a, 17b) for retaining the distribution device (7) inside the chamber (6) at least in part made in one piece with the wall (4a-4d) of the header (4).

A plate for a heat exchanger includes a substantially planar body having a first end, a second end opposing the first end, a fluid surface, and an outer surface. A first cup extends from the outer surface of the body adjacent the first end of the body. A second cup extends from the outer surface of the body and is spaced from the second end of the body.

A stacked heat exchanger includes: passage tubes stacked with each other to support a heat exchange object, a passage being defined in the passage tube for a heat medium to exchange heat with the heat exchange object; and a pipe connected to one of the passage tubes located at one end in a stacking direction of the plurality of passage tubes. Each of the passage tubes has a protruding pipe portion protruding in the stacking direction and communicating with the adjacent passage tube in the stacking direction. The one of the passage tubes located at the one end in the stacking direction is an in/out passage tube. The pipe has a surface at one end in a longitudinal direction of the pipe, and the surface intersects the longitudinal direction of the pipe and is joined to the in/out passage tube.

A system for connecting housing elements of a device for heat transfer having a housing with a first housing element and a second housing element which are connectable with one another with face sides oriented toward one another and via a connection under form closure. Housing elements are herein in contact on another with side margins developed in proximity of front faces.
