Abstract: A heat exchanger, especially an intercooler for a motor vehicle. The heat exchanger comprises a box, a chamber in which a flowing medium is distributed and/or accumulated, a bundle of tubes, tubes, a tube base, openings, a housing lid, two lateral walls, a stabilizing element, a first receiving element, a first transmission element, a second receiving element, a second transmission element, a force transducing element and a flow guide surface.

Abstract: The invention relates to an exhaust gas heat exchanger comprising a bundle of pipes which consists of exhaust gas pipes and a bypass channel, and a housing which can be cross-flown by an aqueous cooling agent. The bundle of pipes and the bypass channel joins in a common exhaust gas inlet, wherein an exhaust gas valve is arranged for controlling the exhaust gas flow through the bundle of pipes or the bypass channel. According to the invention, the bypass channel is embodied as a special steel tube (10) comprising a covering (11) which is made of a high-temperature resistant plastic and wherein the housing, which can be cross-flown by the cooling agent, is arranged.

Abstract: The invention relates to a device for influencing or regulating an air flow for a motor vehicle, the device comprising a flexible film element (8) provided with a plurality of openings for the passage of an air flow, and a rigid carrying element (9) on which the film element (8) is held, the film element (8) comprising a plurality of flap elements (7) which correspond to the openings and are defined by a flap edge (7a) which penetrates the film element (8) and only partially surrounds the flap element (7). The aim of the invention is to produce a device for regulating an air flow for a motor vehicle that can be economically produced and has a high durability with a low susceptibility to dirt accumulation. To this end, the carrying element (9) has flat regions (9a) and openings, the openings being associated with the flap elements (7) for the passage of the air flow. The film element (8) is arranged on the flat regions (9a).

Abstract: A method for producing a fan wheel (1), in particular for a motor vehicle, which is produced by injection molding of a plastic provided with glass fibers, the casting compound being cast in via a ring or cone gate. Also disclosed is a fan wheel (1) produced by this method.

Abstract: The invention relates to a collecting tank (11), especially a charge-air tank or a coolant tank, consisting of plastic and comprising at least one tie rod (12) which is integrated into the collecting tank (11) or is connected to the same in a fixed manner or in such a way that it forms a single component therewith. Said tie rod (12) comprises at least one insert (13).

Abstract: A guide rail 10 for a cable or Bowden cable window lifter with a guide area 1 with slide faces 11, 12 for holding and the sliding guide of a follower mounted displaceable on the guide rail 10 and with at least one fastening area 31, 32 for connecting the guide rail 10 to a fixing base of a vehicle door is made at least in part of plastics and has a reinforcement area 2 connected to the guide area 1 and with reinforcement elements 20 of ribs and/or webs which are moulded on a surface of the reinforcement area 2 preferably integral and substantially perpendicular to the surface of the reinforcement area 2. The at least one fixing area 31, 32 is part of the reinforcement area 2 and the rear sides of the slide faces 11, 12 of the guide area 1 are not directly connected to the reinforcement elements (20). (FIG. 1).

Abstract: The invention relates to a component, in particular a heat exchanger, in particular for motor vehicles, having a finned tube block. Preferably, at least one inlet chamber and at least one outlet chamber are provided having walls made of a synthetic resin material possessing a heat- and/or chemical-resistant coating.
