In order to be able to use materials of higher strength without the danger of cracks arising during deformation, it is proposed, with reference to a heat exchanger having lamella fins, which are held at a distance from and parallel to each other by shaped collars on the lamella fins and which are penetrated by pipes running parallel to each other in passages through the collars, the internal diameter of the passage in each case matching the external diameter of the pipe and at least partially contacting the external periphery of the pipe, while at the same time exactly preserving the distances between the lamella fins, that tongues are distributed on the periphery of the punched rim of the passage, the free ends of the tongues are bent at an angle to the pipe projecting through the passage, and that these bent tongues provide space locating surfaces for the adjacent parallel lamella fin. Also disclosed is a heat exchanger assembly.

Heat exchanger with fins

A heat exchanger, particularly a coolant evaporator, is provided that has several flat pipes that are arranged parallel to one another and are each expanded at their ends with respect to a central part and are closed off by caps. The expanded ends are provided with connecting openings so that the heat exchange medium can flow to the adjacent pipe. At least one of the caps that are provided for closing off the pipe ends is equipped with a projection extending towards the inside of the pipe and closes off at least one of the connecting openings, so that the production of a heat exchanger of identically constructed flat pipes is simplified, in that by the insertion of correponding caps that either expose the connecting openings to the adjacent pipes or not, it is easy to control the flow of the heat exchange medium inside the flat pipes.

Heat exchanger, particularly a coolant evaporator

A cartridge for purifying exhaust gases from the internal combustion engine of an automotive vehicle or some other source comprising a catalyst support matrix wound of metal foil and a metal jacket housing said support matrix wherein a press fit exists between the exterior of the support matrix and the interior surface of the jacket and the support matrix and the jacket are welded or brazed together within the area of the press fit. Processes and apparatus for producing the cartridge of the invention are also disclosed.

Process for manufacturing a cartridge for purifying exhaust gas

A method is disclosed for clamping together a first and a second part, the first part having a flange thereon, the second part having a groove which may receive the flange. The method includes the steps of placing a deformable seal on the bottom of the groove of the second part, placing the flange of the first part on the deformable seal as the flange is guided into the groove, clamping the first and second parts together while deforming the seal until the seal approximately fills a space defined between a lower surface of the flange and the walls forming the groove, and deforming certain parts of a vertically upright standing area of the second part by rolling the certain parts of the area over an upper surface of the flange into generally horizontal positions while leaving other parts of the area generally in their vertically upright condition to thereby form an approximately corrugated edge on the second part, which holds the first and second parts together in a clamped condition. A device for establishing a clamping connection in this manner is also disclosed.

Method for clamping together heat exchanger parts

Method for producing a cartridge for purifying exhaust gas

A clamping connection for clamping two parts together. One part includes a flange and the other includes a deformable edge. When the parts are in their clamped condition, the edge has been deformed into a continuously corrugated configuration including alternate deformed and undeformed partial areas. The deformed partial areas positively and lockingly engage the flange when the flange and edge are in the locked condition. Thus, a positive joint is formed. The undeformed partial areas of the edge contribute to stiffening the clamping connection.

Clamping connection

Disclosed is a clamped connection for clamping together separate parts, comprising a first part having a flange; a second part having an edge and an edge region adjacent to the edge. The edge region is deformable from a first condition in which the edge region is continuous and straight or has a constant radius of curvature along most of its length and a second condition in which the edge region has a continuously corrugated configuration including alternately deformed and undeformed partial edge region areas. The edge region includes a plurality of elongated apertures spaced from the edge and extending generally parallel thereto, and the deformed partial edge region areas are bounded on the side opposite to the edge by these apertures, whereas the undeformed partial edge region areas are located between said apertures. Also disclosed is a device for clamping together two parts to produce the disclosed connection.
