A header for a header tank of a heat exchanger comprises a header wall defining a tube receiving portion having a plurality of longitudinally spaced tube openings formed therethrough. The tube receiving portion includes a planar portion and an adjacent offset portion. The planar portion is disposed on a first plane and the offset portion has a variable distance from the first plane as the offset portion extends away from the planar portion with respect to a longitudinal direction of the header.

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 power connector includes a housing having a terminal channel and a terminal received in the terminal channel including a mating pin at a front of the terminal and a cable connector at a rear of the terminal. The mating pin is positioned in the terminal channel for mating with a charging connector. The cable connector includes a pad configured to be terminated to a power cable. The power connector includes a heat exchanger thermally coupled to the pad of the terminal. The heat exchanger includes a coolant channel for coolant flow through the heat exchanger for actively cooling the terminal. The heat exchanger includes a thermally conductive separator electrically isolating the heat exchanger from the pad of the terminal.

Provided is an integrated heat exchanger including a header tank in which a gasket is interposed between the header and the tank to seal a portion that the header and the tank are coupled to each other, wherein an inner space of the header tank is partitioned such that a first space portion formed between regions in which the heat exchange medium flows is formed to be in communication with an external region of the header tank through a heat exchange medium discharging means formed at a portion that the header and the tank are coupled to each other, thereby preventing the heat exchange mediums from being leaked between two heat exchange portions and to detect a leakage of the heat exchange medium even when the leakage of the heat exchange medium occurs.

A heat exchanger assembly including an elongated tubular heat exchanger enclosure defining an interior chamber. A tube sheet is positioned within the interior chamber of the heat exchanger enclosure separating the interior chamber into a shell side and a channel side. The interior portion is configured to removably receive a tube bundle positioned within the shell side of the interior chamber. An annular sleeve member is positioned within the channel side of the interior chamber of the heat exchanger enclosure. An annular elastic torsion member is positioned within the channel side of the interior chamber of the heat exchanger such that the sleeve member is positioned between the tube sheet and the elastic torsion member. The elastic torsion member has an inner circumference deflectable relative to its outer circumference for torsioning the elastic torsion member.

A heat exchanger includes a plurality of members made of aluminum or aluminum alloy, and a bundling component. The bundling component includes a main body portion having an anchoring portion, and a band portion extending from the main body portion and having a section on an opposite side of a main body portion side anchored in the anchoring portion. The bundling component is made of aluminum or aluminum alloy. At least part of the bundling component and at least part of the plurality of members are secured to each other with a brazing material interposed between the parts.

An integrated heat exchanger in which a flow path, in which a first heat exchange medium flows, and a flow path, in which a second heat exchange medium flues, are separated by a baffle, and includes a support surface having a slope of which the height lowers toward the outside, and formed at a header portion coming in contact with a gasket baffle sealing part, and the gasket baffle sealing part formed in a shape corresponding to the support surface of a header such that the deformation of a gasket is prevented during coupling; and problems in which the gasket of a coupling part, at which the baffle is positioned, is non-uniformly compressed or the gasket is broken or separated from a designated position by means of force of the other direction is prevented.

A header for a header tank of a heat exchanger comprises a header wall defining a tube receiving portion having a plurality of longitudinally spaced tube openings formed therethrough. The tube receiving portion includes a planar portion and an adjacent offset portion. The planar portion is disposed on a first plane and the offset portion has a variable distance from the first plane as the offset portion extends away from the planar portion with respect to a longitudinal direction of the header.

A collector tube for a heat exchanger, which may have at least one flat tube, may include a base and a cover arranged opposite one another and embodying a longitudinal duct. The base may have at least one passage having an opening for accommodating the at least one flat tube of the heat exchanger. The at least one passage may have a collar, which may extend away from the longitudinal duct. The cover may have at least one notch, which may be located opposite the at least one passage and which may be embodied for accommodating a subarea of the at least one flat tube.
