Abstract: A method for the production of a receiving device for the flow tubes of a heat exchanger with openings for receiving the flow tubes. One opening is at least partially produced by a first forming method and at least partially by a second forming method that is different from the first.

Abstract: A heat exchanger for a motor vehicle, the heat exchanger including a collector extending in a longitudinal direction and having a bottom and a collector box, at least two connections provided in the collector box for feeding and draining a fluid, a plurality of exchange tubes ending in the bottom of the collector, and a separator wall separating the collector into a first partial chamber on the inlet side and a second partial chamber on the outlet side, wherein the separating wall adjoins the bottom while dividing the bottom substantially symmetrically along a center line running in the longitudinal direction, and wherein the separating wall comprises a projection above the bottom, wherein at least one of the centers of the two connections has an offset relative to the center line.

Abstract: The invention is based on a multi-chamber flat tube (V1-V17) having at least two chambers (1, 2) for holding the flow of a fluid, produced by deforming a sheet-metal strip, in particular produced in a bending and/or folding and/or crimping process, in which a closed profile is formed by: opposite wide walls (4, 6) which are connected to one another by means of opposite narrow walls (5, 7) which form in each case one deformed region, with the wide and narrow walls forming outer sides of the profile, with a first wide wall (4) being formed by an inner section of the sheet-metal strip which is situated between side sections of the sheet-metal strip, and with a second wide wall (6) being formed by side sections, which are arranged to the sides of the inner section, of the sheet-metal strip, with the first and second wide walls (4, 6) being connected by means of a web (3) which separates at least two chambers and which forms an inner side of the profile and which is formed by an edge section (3A, 3B) of at least o

Abstract: The invention relates to a metal collecting tank (1) for a heat exchanger, especially for motor vehicles. Said collecting tank is produced by non-cutting shaping from a steel sheet blank, preferably an aluminum sheet, and the collecting tank (1) comprises two approximately parallel sidewalls (1c, 1d) and narrow walls each and an upper side (1b) and at least one connecting piece (3). According to the invention, the at least one connecting piece (3) is configured as one piece with the collecting tank (1) and is shaped from the steel sheet blank.

Abstract: A clamp (1) has been provided for fastening and connecting tubes (2,3), especially for fastening a connecting tube to a heat exchanger for a motor vehicle. At least one terminal area (8) of the inventive clamp (1) is bent back.

Abstract: The invention relates to a heat exchanger, in particular for a stationary UT heating body (1) of a motor vehicle heater. According to the invention, said heat exchanger comprises a ventilation device which is embodied as a ventilation bore (22, 36) which is, in particular, embodied in the separating wall of the upper coolant tank (4) of the heating body and is located at a distance from the feed and return section (10).
