    摘要： The invention relates to a plate-type heat exchanger having a plate block comprising partition plates which delimit flow channel layers between the plates. According to the invention, the partition plates have a solid or folded edge, which projects out of the plane of at least one main side of the partition plates at the edge side, along closed-edge regions which are spaced apart from one another in the peripheral direction by means of intervening open-edge regions. In the plate block, this solid or folded edge is joined in a fluid-tight manner to the opposite edge region of an adjoining partition plate and functions as a lateral boundary for the associated flow channel layer. Such heat exchangers may be used, for example, in automobiles and reactors of fuel cell systems.

    摘要： The invention relates to a heat exchanger, particularly of cross-current design, through which at least two separate media can flow. It comprises plates which are stacked on one another and which are spaced apart from one another in some areas and are in contact with one another in other areas, so that flow paths are formed between respectively adjacent plates in a heat exchange region. The plates have apertures adjacent to the heat exchange region, and the plates are spaced apart from one another by means of shaped-out portions of the plates. Areas succeeding one another about the circumference of the plates have apertures, and these areas are alternately shaped out in opposite directions from the plane of the plates.

    摘要： A method and a device for the draw expansion of metal tubes of oval cross-section uses expansion elements drawn unidirectionally through metal tubes by means of draw elements. The expansion elements are fastened to the draw elements by suspension devices which have a hammer-like contour. The draw elements are preferably made of a rod-shaped material. An apparatus of the invention is an apparatus for mechanically expanding metallic tubes, in particular tubes in heat exchangers. Each individual tube to be expanded is held in at least one holding device and passed through by a drawing mandrel with an expanding element. To prevent jamming of the expanding element in one of the holding devices, the holding devices are provided with lateral guides which are resiliently compliant outward in the radial direction. When the expanding element passes through the metallic tube, the tube is expanded in the radial direction. The forces occurring thereby in the axial direction are absorbed by the holding device, since the tube is seated on a stop in the holding device.

    摘要： In a clamping connection between a plastic water tank equipped with at least one flange and a heat-exchanger tube sheet carrying a deformable edge region, an elastic sealing device being retained therebetween under prestress, and the deformable edge region, before its deformation, extends parallel to the outer contour of the flange and, after its deformation to make the clamping connection, it has first partial regions deformed in an approximately wave-shaped manner over the flange of the plastic water tank, and non-deformed further partial regions extending parallel to the outer contour of the flange. The first partial regions deformed over the flange of the plastic water tank make a positive connection, in which the lower edges of the deformed first partial regions rest on the top side of the flange under prestress. To make deformation easier, the deformable first partial regions are cut free parallel to and at a distance from an outer edge at the height of the flange top edge. In order to guarantee a leak-proof connection even with wide production tolerances it is proposed to form on the top side of the flange of the plastic water tank, at least partially, a sloping face in the region of the deformed first partial regions, the sloping face descending toward the outer contour of the flange, and the lower edges of the respective deformed first partial regions being deformed over this sloping face.
