A method for producing a flat tube for a heat exchanger, in particular for a motor vehicle, having a first wall, a second wall opposite to the first wall, having a third wall connecting the first and second wall, having a fourth wall connecting the second and first wall, wherein the first and second wall are longer than the third and fourth wall, having an interior for a medium to flow through, wherein a turbulence insert is arranged in the interior, wherein the method comprises at least the following process steps: —providing a plate material—forming the plate material into an intermediate tube in such a way that the plate material is crowned in at least two sections and the sections at least partially form the first and second wall of the flat tube and the intermediate tube forms an opening in the area one of the two third or fourth walls—providing and inserting a turbulence insert into the interior—closing the opening by means of a welding method.

Method for producing a flat tube

A flat tube for an exhaust gas cooler including two flat wide sides and two rounded narrow sides. The flat tube further including a plurality of moulded turbulence projections arranged on the two wide sides in two flow rows and projecting from a respective one of the two wide sides toward the other of the two wide sides. The plurality of turbulence projections are respectively structured in an elongated manner and arranged at an angle relative to a longitudinal direction. The flat tube also including a plurality of moulded support projections projecting from a respective one of the two wide sides away from the other of the two wide sides. The plurality of support projections are arranged between the two flow rows. The two narrow sides each have an elongated flat region that merges into the two wide sides via a plurality of rounded corner regions.

Flat tube for an exhaust gas cooler

The invention relates to a flat pipe, comprising two substantially flat first walls that are opposite each other and arranged parallel to each other, two arcuate second walls that connect the two flat first walls, and an interior through which a medium can flow, wherein projections that protrude into the interior are provided in at least one of the flat first walls, wherein projections that protrude into the interior are provided in the arcuate second walls.

Flat pipe

A method for the production of a heat exchanger is provided, particularly a sorption heat exchanger, in which several components of the heat exchanger have a ferrous based material, such as pipes, the pipes finishing the bottoms, and the bottoms and the pipes enclosing the housing components are coffered and then soldered. In one method, which reliably realizes the soldering of the joints with different widths, a brazing foil is introduced during the coffering of the components of the heat exchanger formed of steel or stainless steel between the joints of the components of the heat exchanger, and then the joints are filled with a low-melting solder and soldered without flux material.

Method for the production of a heat exchanger, particularly a sorption heat exchanger

The invention relates to a module for a heat pump, comprising an adsorption-desorption region, wherein in the region a bundle of pipes through which fluid can flow is arranged and a housing encloses the pipe bundle and a movable working medium in a sealing manner, wherein a supporting structure forms a mechanical support of a wall of the housing against the action of an external pressure.

Module for a heat pump

A device for the exchange of heat between a first and a second medium with pairs of trays stacked one on top of the other in a stacking direction is provided, wherein a first flow chamber that can be flowed through by a first medium is provided between the two trays of at least one pair of trays or several pairs of trays and a second flow chamber that can be flowed through by a second medium is provided between two pairs of trays adjacent to one another, wherein the first flow chamber has first flow path with flow path sections that can be flowed through consecutively in opposite directions for the first medium, which are separated from one another by a division wall arranged between the at least two trays of the at least one pair of trays, and wherein the second flow chamber has a second flow path for the second medium.

Device for the exchange of heat and motor vehicle

The invention relates to a method for producing a tube for a heat exchanger, in particular for a motor vehicle, in which a long tube, which is provided with turbulence inserts on the surface thereof, is separated into at least two individual tubes. In order to further reduce the production costs and nevertheless achieve a clean cutting surface, a first part of an at least two-part cutting device is introduced into the interior of the long tube through at least one opening of the long tube and the second part of the cutting device is placed against the outer face of the long tube approximately opposite of the inner, first part of the cutting device, wherein the first part and the second part of the cutting device are pressed against one another in order to dividing the long tube.

Method for producing a tube for a heat exchanger, in particular for a motor vehicle

An adsorber structure for a heat pump, having at least one pipe, through which a heat-transfer fluid can flow, and an adsorption medium, wherein a working medium can be adsorbed and desorbed on the adsorption medium and the adsorption medium is in thermal connection with the pipe, wherein the adsorption medium is designed as at least one, in particular several, molded bodies, which is/are directly adjacent to a pipe wall of one of the pipes.

Adsorber structure and module for a heat pump

A tube plate for exhaust heat exchangers, with punched openings to hold the tube ends of a tube bundle, wherein the openings are arranged grid-like with a web width b, and each of the openings has a shear surface with a height h produced by punching, and a bevel of depth t, that is manufactured before punching, and wherein the height h is roughly the same as or smaller than the web width b, is disclosed.

Tube plate for exhaust heat exchanger

The invention relates to an exhaust gas heat exchanger for motor vehicles, comprising a cluster of exhaust pipes () which are soldered on the front surface thereof to pipe bottoms, and a housing jacket () which is welded to the pipe bottoms (). According to the invention, the pipe bottoms are welded to the housing jacket () by means of peripheral welds ().

Exhaust gas heat exchanger and method for the production thereof

In a heat exchanger used especially as an exhaust heat exchanger, provision is made for tube sheets, the tubes of a tube bundle, and a housing to be shaped from stainless steel sheets. The tube sheets are formed as deep-drawn and stamped parts, each of which has a circumferential wall that projects outward beyond the ends of the tubes in the tube bundle. The walls are welded to the housing, and each of the walls is abutted by a diffuser.
