A stripper for stripping a urea/carbamate mixture. The stripper comprises a shell and a plurality of tubes disposed within the shell. A shell-side space is provided between the tubes and the shell. A first heating fluid inlet, a second heating fluid inlet, and a heating fluid outlet are in fluid connection with the shell-side space. The second heating fluid inlet is disposed between the first heating fluid inlet and the heating fluid outlet. Related uses, systems, and methods are provided as well.

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.

A heat exchanger and methods of manufacturing and assembling a heat exchanger, and more particularly to an air-flow heat exchanger having a mechanically assembled header for use in a motor vehicle. The heat exchanger comprises an all-metal bonded matrix including a plurality of substantially parallel metallic tubes and a plurality of metallic fins. The tubes have a heat transfer portion that is elongate in cross-sectional shape, and which comprises two opposing, longer sides, and two opposing shorter sides. At least one of the tubes is mechanically joined at a first end portion thereof to a first header of the heat exchanger by at least one compliant member. The compliant member extends around the first end portion of the tube to provide a seal and to permit relative movement between the mechanically joined tube and the first header due to thermal expansion and contraction of the matrix.

The present disclosure relates to a heat exchanger including a plurality of fluid guiding metal pipes (2) having pipe ends (3) arranged side by side at intervals, at least one pipe bottom (4) made of plastic and having receiving through-holes (5) in which the pipe ends (3) may be received, and a collection box (6) made of plastic and which may be connected to the pipe bottom (4) by a locking device formed between the pipe bottom and the collection box, wherein a seal (9) may be inserted between the pipe bottom (4) and the collection box (6), and the seal ensures press-fit of the pipe bottom (4) on the pipe ends (3) and seals the collection box (6) against the pipe bottom (4) and the pipe bottom (4) against the pipe ends (3).

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.

The invention relates to a heat exchanger comprising one tube, and preferably a plurality of tubes, which extend through a heat-exchange chamber starting from a tube sheet, wherein the tube sheet is made of a fiber-reinforced plastics material. The invention further relates to a method for producing a heat exchanger of this kind and to the use of a heat exchanger of this kind.

A main header for an internal combustion engine radiator has cut-outs and V-shaped notches provided at the four corners of the main header. The cut-outs and V-shaped notches release the stresses after the main header is flanged, thereby ensuring the flatness or straightness of the main header. The main header further includes one or more strengthening strips disposed along the length sides and the width sides of the main header, and optionally at the region adjacent to the cut-outs, to further enhance the flatness of the main header.

A heat exchanger for a method vehicle and a method of producing a heat exchanger are disclosed. The heat exchanger includes a heat exchanger block closed by a side part. The heat exchanger block has a tube bottom including a deformable hook, and the side part includes a tab provided complementary to a corner region of the tube bottom. The tab has a section, that abuts on a front side of the tube bottom, that includes a through opening or depression. A material portion of the hook is displaced through the through opening or depression via a graining in an assembled state, such that the axes of the through opening and the graining are offset and parallel to one another.

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.

A liquid-cooled cold plate for removing heat from a heat-generating component is disclosed. The liquid-cooled cold plate includes a lower heat transfer plate with a flat component contact surface constructed to make thermal contact with the heat-generating component, and a plurality of parallel turbulator channels, holding a plurality of turbulators, the channels having walls that extend away from the component contact surface. The liquid-cooled cold plate also includes a lid forming a liquid tight seal with the lower heat transfer plate. The lid has an inlet end with an inlet port in fluid connection with an inlet channel manifold that allows for fluid communication between the plurality of parallel turbulator channels and the inlet port. The lid also has an outlet end with an outlet port in fluid connection with an outlet channel manifold that allows for fluid communication between the plurality of parallel turbulator channels and the outlet port.
