A thermal management system for an electric component has a housing for the electric component and a heat exchange plate extending over the surface of the lateral face of the housing. The plate has a fluid channel between a fluid inlet and a fluid outlet, a supply duct to supply the plate with fluid and a discharge duct, a casing defining the housing(s) and receiving the heat exchange plate and the supply and discharge ducts. The system includes a fluid collecting box arranged to collect fluid from a possible fluid leakage at the junction between the fluid inlet and the fluid outlet of the plate and the associated supply and discharge ducts, so as to prevent said leaked fluid from dripping into a bottom of the casing.

In accordance with at least one aspect of this disclosure, a transition structure for a heat exchanger can include a body defining a dome cavity. The dome cavity can be configured to transition flow between at least one first channel and a plurality of second channels having a different number than the at least one first channel.

A heat exchanger, including at least one flat pipe, each flat pipe is provided with a refrigerant cavity, an inlet, an outlet and two through holes, the inlet and the outlet are located at two ends of the refrigerant cavity, respectively, and both the inlet and the outlet communicate with the refrigerant cavity; the two through holes are respectively located at two ends of the refrigerant cavity, and the two through holes do not communicate with the refrigerant cavity. The flat pipe is provided with the inlet, the outlet and two through holes, when the plurality of flat pipes are matched with liquid collecting pipes (liquid inlet pipes or liquid outlet pipes) of the heat exchanger, different flat pipes can choose to use the inlets or outlets to communicate with the liquid collecting pipes, and the through holes are able to be used to avoid the liquid collecting pipes.

A corner assembly arrangement for a heat exchanger is provided. The corner assembly has a manifold having a tubular metal vessel and a side plate consisting of a flat metal plate extending orthogonally to the manifold and attached to an end thereof. The side plate has an end tab that extends in a zigzag pattern from a respective end of the side plate and has a support end in contact with a wall of the manifold. The support end has, according to a plan view, a concavity configured to fit the wall of the manifold.

A radiator core includes a head tube and a tube module mounted on the head tube. The head tube is provided with multiple tube slots having multiple first sides and multiple second sides. The tube module includes multiple first tubes and multiple second tubes mounted in the tube slots. Each of the first tubes is provided with a first connecting portion having an increased thickness and resting on one of the first sides of the tube slots. Each of the second tubes is provided with a second connecting portion having an increased thickness and resting on one of the second sides of the tube slots.

A heat exchange device includes a core and a housing. The core includes a first collecting part and a second collecting part, and a flat tube part is provided between the two. The flat tube part includes a first flat tube group and a second flat tube group. The first collecting part includes first and second collecting portions, and a separator is formed between the two. Each flat tube of the first flat tube group is communicated with the collecting cavity of the first collecting portion. The collecting cavity of the first collecting portion is communicated with the collecting cavity of the second collecting portion through the first flat tube group, the collecting cavity of the second collecting part, and the second flat tube group.

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 core having a plurality of tubes, each tube having a tube inlet and a tube outlet, and the tube inlets define an inlet plane and the tube outlets define an outlet plane. The tubes are spaced from one another for receiving a second fluid therebetween, for heat transfer between the first and second fluids. A jacket is provided adjacent the core for use in containing the second fluid, and the jacket comprises a jacket inlet for passage of the second fluid en route to the core. The jacket extends between the inlet plane and the outlet plane, and the jacket inlet is offset from the inlet plane towards the outlet plane. The heat exchanger further comprises a deflector arrangement for directing a flow of second fluid from the jacket inlet towards the inlet plane prior to entering the core.

A cracked gas cooling heat exchanger includes a tube connection between an uncooled tube (1) and a cooled tube (2), having a cooled inner tube (3) enclosed by a jacket tube (4), with a tube intermediate space (5) for flowing cooling medium. A gas inlet header (11) has a GI tube inner part (12) and a GI tube outer part (13) and a cooling space (14) with an insulating layer (15). The GI tube outer part connects via a water chamber (6) to the jacket tube. The GI tube inner part faces the inner tube and is connected on a face (8) of the water chamber. A weld backing ring (16), between an end face (9) of the cooling space and a bottom face (8) of the water chamber, is in the insulating layer of the cooling space, arranged in a turn-out/groove (17) in the insulating layer.

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.
