The present invention relates to a heat exchanger (2) having a jacket (10) through which a first medium (A) can flow and which has at least one first inlet (11) and at least one first outlet (12), at least one tube (30) through which a second medium (B) can flow, the tube (30) being guided through the jacket (10) and having at least one second inlet (31) and at least one second outlet (32), wherein a deflection segment (50) or a plurality of deflection segments (50) are arranged in a row in a longitudinal axis (X) in the jacket (10), wherein the deflection segment (50) is formed from at least two partial sections (51, 52), which are arranged so as to overlap and cross, in areas, transverse to the longitudinal axis (X).

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 housing with an inlet port, an outlet port, an interior facing surface defining a coolant channel, a first opening surrounded by an exterior facing surface, and a second opening defined by a first inner diameter. A tube assembly defines a plurality of exhaust gas flow channels and a plurality of coolant cross channels within the housing. A first diffuser directs a first fluid into the tube assembly and is joined to a first header plate, which separates the first fluid from a second fluid within the coolant channel. A second diffuser directs the first fluid out of the tube assembly. The second diffuser is located within the second opening and sealed to the second opening by seals around the second diffuser.

In cooling/heating cycles of a heat exchanger, to prevent cracks that tend to occur in a brazed portion between an end portion of a horizontal cross-section of a tube and a header plate. An end portion cover body is provided for an end portion of a tank main body or a header to cover hereby an end portion in a longer side direction of an opening end portion of a flat tube.

A heat exchanger includes a separator member that divides a first flow passage from a second flow passage. The heat exchanger also includes a plurality of first hollow members that extend across the first flow passage at respective non-orthogonal angles. The plurality of first hollow members are fluidly connected to the second flow passage. Moreover, the heat exchanger includes a plurality of second hollow members that extend across the second flow passage at respective non-orthogonal angles. The plurality of second hollow members are fluidly connected to the first flow passage.

A heat exchanger includes a shell, a refrigerant distributor, and a heat transferring unit. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends generally parallel to a horizontal plane. The refrigerant distributor is connected to the refrigerant inlet and disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant and a refrigerant vapor distribution outlet opening longitudinally spaced from the shell refrigerant vapor outlet. The heat transferring unit is disposed inside of the shell below the refrigerant distributor so that the liquid refrigerant discharged from the refrigerant distributor is supplied to the heat transferring unit.

A heat exchanger is disclosed having a tube bundle, intended to internally receive a first fluid, and a shell with an inlet opening at a first end. The shell allows an internal circulation of a second fluid and is arranged to surround the tube bundle. An inner casing to the shell circumscribes the bundle within a heat exchange chamber so that between the casing and the shell an annular region extending in a continuous way along the length of the bundle is defined. The annular region is in fluid communication with the exchange chamber through an outflow opening obtained at a second end of the inner casing where the latter has a rear wall facing an opening of the shell to outlet the second fluid from the heat exchanger. The inlet and outlet openings are in fluid communication by means of the annular region.

A shell and tube heat exchanger includes a tube bundle for passage of a first medium from a first inlet to a first outlet. A second medium flows through a flow space which surrounds the tube bundle. The tube bundle includes first tubes communicating with the first inlet, and second tubes communicating with the first outlet and fluidly connected to the first tubes. The first tubes define an outer enveloping surface which is predominantly adjacent to an enveloping surface of the second tubes. A separating body between the first inlet and a tubesheet which separates the flow space from the first medium prevents the first medium from flowing against the tubesheet and includes inlet tubes which bridge a compensation space between the separating body and the tubesheet and which protrude into the first tubes to direct the first medium into the first tubes while bypassing the tubesheet.

A heat exchanger having a circulation guide, the heat exchanger comprising: a heat exchanger body; an inlet port, which is connected to a bottom end of the heat exchanger body; a discharge port which is connected to a top end of the heat exchanger body; a top body tube installed at a top end of an inside of the heat exchanger body; a bottom end plate installed at a bottom end of the inside of the heat exchanger body; and combustion pipes, which each have a top end connected to pass through a floor surface of the top body tube.

A shell and tube heat exchanger includes a tube bundle for passage of a first medium from a first inlet to a first outlet. A second medium flows through a flow space which surrounds the tube bundle. The tube bundle includes first tubes communicating with the first inlet, and second tubes communicating with the first outlet and fluidly connected to the first tubes. The first tubes define an outer enveloping surface which is predominantly adjacent to an enveloping surface of the second tubes. A separating body between the first inlet and a tubesheet which separates the flow space from the first medium prevents the first medium from flowing against the tubesheet and includes inlet tubes which bridge a compensation space between the separating body and the tubesheet and which protrude into the first tubes to direct the first medium into the first tubes while bypassing the tubesheet.
