A main header for an internal combustion engine radiator has cut-outs and V-shaped notches provided at the four corners of the main header. The cut-outs and V-shaped notches release the stresses after the main header is flanged, thereby ensuring the flatness or straightness of the main header. The main header further includes one or more strengthening strips disposed along the length sides and the width sides of the main header, and optionally at the region adjacent to the cut-outs, to further enhance the flatness of the main header.

A support and connection device is for an operating group of a vehicle. The support and connection device is configured for supporting and for fluidic connection with an operating device in turn included in the operating group. The support and connection device identifies a vertical axis and two longitudinal axes and includes at least one plate-shaped unit in which, in the vertical direction, there is at least one mouth for the passage of a working fluid. The plate-shaped unit includes an upper laminar element, a lower laminar element reciprocally stacked along the vertical axis and a hollow space between them. The at least one mouth for fluid passage is defined laterally by a fluid mouth wall constituted by the reciprocal engagement of an upper mouth rim included in the upper laminar element and by a lower mouth rim included in the lower laminar element.

A collector tube for a heat exchanger having at least one flat tube, may include a base and a cover arranged opposite the base. The base and the cover may define a longitudinal duct. The base may include at least one passage having an opening configured to accommodate the at least one flat tube of the heat exchanger. The opening may have at least one wide edge and at least one narrow edge. The longitudinal duct may have, in a cross section, a diameter that is smaller than the at least one wide edge of the opening. The at least one passage may include a collar extending away from the longitudinal duct.

A heat exchanger arrangement is provided with a housing provided with a fluid inlet and a fluid outlet and designed to be flowed through by the fluid. A heat exchanger is arranged in the housing between fluid inlet and fluid outlet and surrounded by the housing. The heat exchanger is arranged such that the fluid can flow through the heat exchanger. The housing has a seal contour. The heat exchanger is connected with form fit at a fluid inlet of the heat exchanger or at a fluid outlet of the heat exchanger to the seal contour of the housing. In a method of producing the heat exchanger arrangement, a seal surface of the seal contour of the housing is melted and pressed against a seal region of the heat exchanger at the fluid inlet of the heat exchanger or at the fluid outlet of the heat exchanger.

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.

A profile for a header of a cooler which also includes numerous parallel tubes. The parallel tubes have a cross-sectional shape between slots for the tubes which further include at least two wave troughs Further, a header is also included having such a profile. A cooler may also be provided, wherein the cooler has such a header.

A heat exchanger includes a shell housing a plurality of tubes and defining an exhaust fluid flow path within a first volume enclosed by the shell. The outer surfaces of the plurality of tubes are in fluid communication with the exhaust fluid flow path. The heat exchanger includes a cap attached to a first end of the shell and defining a second volume. A header is configured to separate the first volume from the second volume, flex with thermal expansion, and define tube inlet and outlet positions. The tube inlets and outlets are in fluid communication with a source fluid flow path, and each tube is substantially U-shaped and defines a flow path of the source fluid within the exhaust fluid flow path. The heat exchanger includes at least one longitudinal flow baffle within the shell configured to reduce an amount of exhaust fluid that may bypass the tubes.

A heat exchanger for a motor vehicle may include a tube block and a flange. The tube block may multiple first medium channels and multiple second medium channels. The first and the second medium channels may extend from an inlet of the tube block to an outlet of the tube block. A medium to be cooled may flow through the first medium channels. A cooling medium may flow through the second medium channels. The flange may be configured to receive the tube block about the outlet in a fluid-tight manner. The flange may be plate-like and may have a surrounding bolting region that may be formed about the tube block.

Systems and methods for using spring force based compliance to minimize the bypass liquid flow gaps between the tops of chip microfins and bottom side of manifold ports are disclosed herein. A fluid delivery and exhaust manifold structure provides direct liquid cooling of a module. The manifold sits on top of a chip with flow channels. Inlet and outlet channels of the manifold in contact with flow channels of the chip creates an intricate crossflow path for the coolant resulting in improved heat transfer between the chip and the working fluid. The module is also designed with pressure reduction features using internal leakage flow openings to account for pressure differential between fluid entering and being expelled from the module.

An heat exchanger and method for forming the heat exchanger, the heat exchanger including a cooling architecture comprising at least one unit cell having a set of walls with a thickness, the set of walls defining fluidly separate conduits having multiple openings, each of the multiple openings having a hydraulic diameter, wherein an average fluid temperature (T.sub.f) to material temperature limit (T.sub.m) ratio (T.sub.f/T.sub.m) is greater than 0 and less than or equal to 1.25 (0<T.sub.f/T.sub.m≤1.25), and wherein the thickness (t) and the hydraulic diameter (D.sub.H) relate to each other by an equation:

[00001]$\frac{T_f}{T_m}.Math.\frac{D_H^{2/3}\left(D_H+t\right)}{{\left(D_H+2t\right)}^{8/3}}$
