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 heat exchanger includes a duct, a core portion, and a caulking plate. The duct has an inlet and an outlet. The core portion is housed in the duct in a state where cooling plates and cooling fins are stacked in a stacking direction. The caulking plate has a frame shape corresponding to an opening shape of the inlet and the outlet and brazed to the inlet and the outlet. The caulking plate is interposed between the duct and a tank to fix the tank. A first joint between the duct and the core portion and a second joint between the duct and the caulking plate are distanced from each other in the stacking direction by a predetermined distance. The duct has a rib between the first joint and the second joint or at the second joint.

A heat exchanger (1) comprising a heat-exchange core (2) in which a plurality of tubes (28) in which a second fluid circulates and a plurality of dissipation devices (30) between which a first fluid circulates are received, and at least one manifold (8) defining an internal volume (42) through which the first fluid passes and facing which is a foot (48) of said manifold (8), the heat exchanger (1) also comprising a connecting part (10) disposed between the heat-exchange core (2) and the manifold (8), the connecting part (10) comprising at least one tab (72) which extends in the internal volume (42) of the manifold (8) and so as to partially overlap the foot (48) of the manifold (8).

A liquid to refrigerant heat exchanger includes an enclosed coolant volume that is at least partially defined by a plastic housing and by a metal closure plate. The metal closure plate can be part of a brazed assembly containing a continuous refrigerant flow path. The refrigerant flow path is disposed within the coolant volume, where heat can be transferred between the refrigerant within the refrigerant flow path and the liquid within the coolant volume. The plastic housing can at least partially surround the refrigerant flow path to at least partially bound a liquid flow path along a portion of the coolant volume. An inlet diffuser and an outlet diffuser can be mounted to the housing to direct the liquid through the housing. The plastic housing is sealingly joined to the closure plate along an outer periphery of the closure plate.

A tank for a heat exchanger is provided. The tank includes a foot portion, an internal wall, a sealing member and at least one first coupling member. The internal wall is formed along the foot portion at a first end of the foot portion. Further, the sealing member is disposed on the foot portion along an outer circumference of the internal wall to provide a fluid-tight sealing between the tank and a header, when the tank is placed on the header. The at least one first coupling member is provided on the foot portion, adjacent to the sealing member, to couple with the header.

The header-tank assembly includes a tank, a header a sealing element. The tank includes foot portions configured on at least one pair of opposite sides thereof. The header includes tabs configured on at least one pair of opposite sides. The tabs are crimped along fold lines configured thereon to receive the respective foot portions of the tank and configure connection between the header and the tank. The sealing element is disposed between the foot portions of the tank and the header. A notch is configured on an outside wall of each tab, wherein the notch extends along the fold line to facilitate crimping of the tabs over the respective foot portions and is visible after crimping operation.

An embodiment integrated radiator includes an upper section including an upper tube, a first upper tank, a first upper header, a second upper tank, and a second upper header, wherein the upper tube is configured to pass an upper-side coolant therethrough, a lower section including a lower tube, a first lower tank, a first lower header, a second lower tank, and a second lower header, wherein the lower tube is configured to pass a lower-side coolant therethrough, and a middle section disposed between the upper section and the lower section, the middle section including a middle tube, a first middle tank, a first middle header, a second middle tank, and a second middle header, wherein the middle tube is configured to receive a cooling medium therein.

The present invention reduces and mitigates thermal stress generated at joint portions between a header plate and a flat tube of a heat exchanger. In a direction of a vertical center axis passing the center of the inside of a flat tube, positions of first brazing parts are set to be closer to the center of the flat tube in the direction of the vertical center axis than positions of edge brazing parts. Accordingly, the thermal stress concentrated at the joint portions between short sides of the flat tube and the header plate is dispersed to other portions.

A header for a heat exchanger includes a header frame defining an opening and including a base portion circumscribing a perimeter thereof. A mounting tab extends from the base portion. The mounting tab is configured to bend inwardly with respect to the header frame. A deformation featured is formed on one of an inner surface and an outer surface of the header frame and is configured to facilitate bending of the mounting tab

Systems, devices, and methods are disclosed for attaching two automotive components comprising different materials having different coefficients of expansion, comprising providing a flange around a perimeter of each of the components, wherein at least one component defines a plenum contiguous to the perimeter, providing corresponding inner faces of the flanges, providing a channel in at least one of the corresponding faces of the flanges, wherein the channel is coaxial to the perimeter, disposing a gasket in the channel, and surrounding the flanges with a locking ring, wherein the ring has an axial channel and a pin disposed perpendicular to the channel to secure a first end of the locking ring to a mating second end of the locking ring.
