A heat exchanger may include a tubular housing, a flange ring, two bases, and heat exchanger tubes that run through the housing and are each held in the bases at a longitudinal end side. A first flow channel may be formed in the heat exchanger tubes, and a second flow channel may be formed between the heat exchanger tubes and the housing. The housing may be formed from two one-piece and pot-shaped housing parts. Each housing part may have a housing section, a flange ring section, and a base. The two housing parts may be connectable to one another via the two flange ring sections.

Disclosed a heat exchanger comprising: a plurality of parallel tubes for conveying a first fluid, a pair of header plates, each having a plurality of openings into which respective ends of the tubes are inserted in a fluid-tight manner, a jacket connected to the header plates in a fluid-tight manner and defining with the header plates an inner volume for receiving a second fluid, the tubes being placed within the inner volume, and a fluid channel joined to a wall of the jacket, the fluid channel being in fluid communication with the inner volume through an opening formed through the wall, wherein the wall is, on an opposite side relative to the fluid channel, joined to sidewalls of said tubes.

A heat-exchange apparatus comprising a plurality of tubes bundled together, each having segmented twisted segments is disclosed. Each of the plurality of tubes provides a tube body defining an interior passageway for carrying a first fluid and a plurality of segments along its length comprising a straight section and a twisted section that are in fluid communication with each other. Each of the plurality of tubes provides a central longitudinal axis along its length. The tube body along the twisted section exhibits rotation about the central longitudinal axis and the tube body along the straight section exhibits no rotation. An exterior surface of the tube body of a tube can come into contact with an exterior surface of the tube body of another tube along the twisted section, whereas the exterior surfaces of such tubes avoid contact along the straight section.

A tube type heat exchanger includes a core includes multiple tubes, a header plate defining an array of apertures in which said tubes are received, and a coolant jacket arranged about said core. The header plate includes a body defining a central region and an edge region circumferential to said central region. The central region defines said array of apertures. The edge region includes a flange. The header plate is connected to the coolant jacket via first and second contact areas between the header plate and the coolant jacket. The flange is outboard of the coolant jacket. The first contact area is between the flange and the coolant jacket; and the second contact area is inboard of the first contact area.

A heat exchanger (4) has fluid flow channels (6) with at least one heat exchanging surface (10) which has an undulating surface section for which the surface profile varies along a predetermined direction such that at a first edge (E1) the surface profile follows a first transverse wave (20), at a second edge (E)2 the surface profile follows a second transverse wave (22) and at an intermediate point I between the edges the surface profile follows a third transverse wave (24). The third transverse wave (24) has a different phase, frequency or amplitude to the first and second transverse waves so that chevron-shaped ridges and valleys are formed. This improves the mixing of fluid passing through the channel and hence the heat exchange efficiency.

The present disclosure discloses a header box and a heat exchanger. The header box includes a cover plate and a bottom plate. The cover plate is provided with a groove extending along a length direction of the cover plate. The groove includes an opening portion. The bottom plate is provided with a number of openings for inserting flat tubes. The opening extends through an upper surface and a lower surface of the bottom plate. The opening includes a first opening close to the cover plate and a second opening away from the cover plate. A cross-sectional area of the first opening is larger than a cross-sectional area of the second opening. The opening portion of the groove is provided toward the bottom plate. As a result, high pressure resistant performance of the header box and the heat exchanger can be achieved.

A heat exchanger includes a plurality of flat tubes spaced apart from each other and located in parallel, a header configured to connect end portions of the plurality of flat tubes, and a fin joined between the flat tubes adjacent to each other, wherein the fin is provided with a break line configured to break the fin when bending is performed.

An integrated exhaust system apparatus to be mounted on an engine is provided. The apparatus includes an apparatus housing; an engine interface; an exhaust system interface with a first exhaust apparatus outlet configured to direct a first portion of exhaust through the housing wall; an EGR interface with a second exhaust apparatus outlet configured to direct a second portion of exhaust through the apparatus housing wall; and an exhaust manifold arranged within the apparatus interior. The exhaust manifold includes a first manifold outlet configured to direct the first portion of exhaust out of the manifold interior and a second manifold outlet configured to direct the second portion of exhaust out of the manifold interior. An EGR cooler is arranged within the apparatus interior with passages fluidly coupled such that the second portion of exhaust is directed out of the apparatus housing via the second exhaust apparatus outlet.

A heat exchanger with a chamber assembly, having a medium directing assembly disposed within. The medium directing assembly provided with a first and a second medium directing panel member, each respectively a planar panel member having a first side and a second side. A heat exchange medium introduced into the chamber assembly in an initial line of flow is vertically diverted into two flows to impact the first side of the first and the second medium directing panel member separately. Each diverted heat exchange medium is then further diverted into a pair of divergent arcuate lateral flow, wherein each lateral flow is directed to impact the lateral sides of the chamber assembly. On the respective second sides of the first and the second medium directing panel member, laterally diverted heat exchange medium is directed to collide into each other, where the pair of laterally diverted flows are subsequently merged.

A heat exchanger includes a body that includes an at least two opposing surfaces and the at least two opposing surfaces are a trapezoidal. The body of the heat exchanger also includes, an area of cross sectional flow channels through the body. The area of cross-sectional flow channels in a direction perpendicular to the bases of the trapezoid increase or decrease between the two bases.
