Techniques for structurally integrated heat exchangers are presented herein. A heat exchanger in accordance with an aspect of the present disclosure comprises a structure configured to enclose a volume for storing a first fluid, and to connect to a load. The heat exchanger further comprises a first and a second header first arranged in opposing inner walls of the structure. The heat exchanger further comprises one or more load-bearing struts extending to connect the first and second headers within the volume and configured to pass a second fluid through the volume for transferring heat to the first fluid, the second fluid configured to cool a different component in the vehicle.

A heat exchanger includes a fluid reservoir having a peripherally extending foot, a header having a mounting tab bent to engage the foot of the fluid reservoir to couple the header to the fluid reservoir, and a retaining feature configured to prevent disengagement of the mounting tab of the header from the foot of the fluid reservoir. The retaining feature overlays at least a portion of an outer surface of the mounting tab while otherwise restrained by a portion of the fluid reservoir in order to prevent the disengagement of the mounting tab from the foot.

A flat heat exchanger tube is formed from a single metal strip and comprising two opposite spaced apart broad sides in a thickness direction of said tube and two opposite nose-forming narrow sides in a width direction of said tube. The strip has two longitudinal edges, the first longitudinal edge being contiguous to the first broad side and the second longitudinal edge being contiguous to the second broad side. The two longitudinal edges of the strip are joined together at a first one of the narrow sides, both longitudinal edges being convex-shaped so that the first edge forms an outer convex bend and the second edge forms an inner convex bend that fits in the outer convex bend and conforms to its internal curvature.

An evaporator with a finned tube block with tubes and fins, wherein the tubes are arranged in rows and the fins are arranged between the tubes, with a first collection and distribution box and with a second collection and distribution box. Each of the two collection and distribution boxes has a bottom and a box lid. The respective bottom has openings for inserting the tube ends of the tubes of the finned tube block. The finned tube block is divided into evaporator flows to which groups of tubes of the finned tube block are assigned. The tubes of an evaporator flow each merge end-side into a box area of a collection and distribution box. The respective bottom of the collection and distribution boxes is designed with rim holes for inserting the tube ends in the openings.

A header (10) for a heat exchanger, in particular for a charge air cooler, comprising an opening plane (12) with plurality of openings (14) for attachment of tubes, a collar (13) encircling the perimeter of the opening plane (12) and protruding at least partially above the opening plane (12), wherein the header (10) further comprises guiding protrusions (11a, 11b) located along inner perimeter of the collar (13) adjacent to said openings (14) and configured to guide the tubes into the openings (14) upon insertion, wherein the openings (14) have substantially rectangular shape with longer sides (14a) and shorter sides (14b) and are arranged in series along their longer sides (14a), wherein a first group of guiding protrusions (11a) is located adjacent the longer sides (14a) of the openings (14), while a second group of guiding protrusions (11b) is located adjacent the shorter sides (14b) of the openings (14).

A fire tube with three hollow tube sections, two of which are parallel to each other and one of which is perpendicular to and connects the ends of the first two tube sections. The bottom-most tube section, which contains the burner, has an inner ceramic liner that is made up of one or more separate ceramic tubular sections. An upper set of cooling fins surrounds the top part of the bottom-most tube section, and a lower set of cooling fins surrounds the bottom part of the bottom-most tube section.

Described herein is a brazed heat exchanger comprising at least one header, manifold and/or tube structured to hold a coolant or refrigerant; said header, manifold, and/or tube component including a plurality of apertures; a plurality of substantially parallel fluid-carrying tubes each extending substantially perpendicular from one of said plurality of apertures in said header plate, manifold, and/or tube component and structured to receive said coolant or refrigerant therethrough; and a plurality of corrugated aluminium alloy fins being in thermal communication with said plurality of fluid-carrying tubes and structured to transfer heat away therefrom. The header, manifold, and/or tube component is made from an aluminium alloy sheet material comprising, in wt. %: Mn 1.4%-1.8%; Si up to 0.7%; Fe up to 0.7%; Mg up to 0.30%; Cu up to 0.10%; Cr up to 0.25%; Zr up to 0.25%; Zn up to 0.50%; Ti up to 0.2%; balance aluminium and inevitable impurities.

The monolithic redundant loop cold plate core includes a core structure and a first cooling loop formed in the core structure. The first cooling loop including: a plurality of first cooling loop passageways extending across a heat exchanger core in one or more passes. The one or more passes include at least a first pass. The monolithic redundant loop cold plate core includes a second cooling loop formed in the core structure. The second cooling loop includes: a plurality of second cooling loop passageways extending across the heat exchanger core in the one or more passes. The plurality of first cooling loop passageways are intermixed in an alternating side-by-side arrangement with the plurality of second cooling loop passageways in a single cooling plane. The monolithic redundant loop cold plate core is a single piece including a unitary structure.

A three-dimensional heat transfer device includes a first thermally conductive casing, a second thermally conductive casing, a first capillary structure, a second capillary structure and a heat pipe. The second thermally conductive casing has a through hole. The second thermally conductive casing is mounted on the first thermally conductive casing so as to form a liquid-tight chamber. The first capillary structure is disposed on the first thermally conductive casing. The second capillary structure is disposed on the first thermally conductive casing. Projections of the first capillary structure and the second capillary structure on the outer surface and an extension surface of the outer surface are located in an extent of the outer surface, and the second capillary structure is located closer to the second thermally conductive casing than the second capillary structure. The heat pipe is disposed through the through hole and in contact with the second capillary structure.

A heat exchanger includes: flat pipes disposed in multiple stages in a stage direction corresponding to an up-down direction; and fins that partition a space between adjacent two of the flat pipes into air flow passages through which air flows. Each of the flat pipes includes a passage for a refrigerant inside thereof. The flat pipes are divided into heat exchange paths arrayed in multiple stages in the stage direction. One of the heat exchange paths that includes a lowermost one of the flat pipes is defined as a first heat exchange path. A length of the passage from a first end to a second end of a flow of the refrigerant in each of the heat exchange paths is defined as a path effective length.
