    摘要： The invention relates to a heat exchanger of the crosscurrent type, through which at least two fluids flow, consisting of plates which are stacked one on the other between two cover plates and which are spaced from one another in regions and are in contact in regions, so that fluid paths are formed between them in a heat transfer region, and of inlet ducts and outlet ducts which are arranged laterally in duct regions and which are formed from inlet duct openings and outlet duct openings in the plates, at least one inlet duct and one outlet duct being fluidically connected to a group of fluid paths which are next but one. The object of the invention is to develop a heat exchanger of the type initially mentioned, in such a way that, while having at least the same operating reliability, it can be produced more efficiently and more cost-effectively and has a lower weight. In order to achieve this object, there is provision for the spacing of the plates to be carried out by means of shaped-out portions of the plates.

    摘要： An electric heating device includes a plurality of heating elements which are assembled to form a block. Such a heating element is formed from two metal plates, with the interposition of PTC elements. In order to increase the heat transfer, the metal plates are provided with corrugation ribs. Each heating element includes a pair of metal plates which are angled off essentially in the form of an L such that the angled-off sections are connected in a frictionally locking manner to each other. The angled-off sections are arranged at opposite ends of the heating elements and angled in opposite directions, the length of the angled-off sections of the metal plates being dimensioned such that angled-off sections of one pair of metal plates are in mutual abutment with angled-off sections of respectively adjacent pairs of metal 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： A heat exchanger assembly and method of making same are disclosed. A plurality of thin walled aluminum tubes are connected to a tube bottom. The tubes are first inserted into the tube support openings in the tube bottom with tube ends flush with a collecting space side of the tube bottom. The tube ends are then welded by a laser beam guided around the circumference of the respective tube ends.
