Abstract: A heat exchanger having a tube-fin block that is closed by two collecting tanks, whereby the ends of the tubes engage in a bottom of the particular collecting tank and the bottom is closed with a cover. A partition wall secured to the cover is formed transverse to a longitudinal extension of the collecting tank and divides an interior space of the collecting tank into two subchambers. The heat exchanger, which prevents great structural changes for compensating temperature-induced stresses, a first stress decoupling device is formed in the bottom and/or a second stress decoupling device in the area of the partition wall in the cover of at least one collecting tank.

Abstract: The application relates to a heat exchanger having a block with ribs and rectangular tubes. The block is arranged between a first collecting box and a second collecting box. Each collecting box is closed off by a base which has eyelets for receiving the tubes, and a trough-shaped circulating section for receiving the collecting box extends along the edge of the base. The base has an elevated contact region on at least one end face for the tube which lies directly opposite the end face in order to allow a stable structure of the heat exchanger, collecting boxes, and block.

Abstract: The invention relates to a frame part for a shell-and-tube heat exchanger. The frame parts should be designed so that given a simplified producibility of the frame parts, a complete compensation for expansion in the longitudinal direction as well as in the transverse direction of the frame part is nevertheless ensured. According to the invention, a frame part for a shell-and-tube heat exchanger comprises a number of tubes, which are parallel to one another, form a tube body, and are flowed through by a heat exchanging medium. The tube body is surrounded by frame parts at least on two sides that are parallel to the tubes. At least one thermal expansion element is formed at least in the frame parts that are oriented parallel to the tubes. The thickness of this thermal expansion element is at least a multiple of that of the material of the frame part where it deviates.

Abstract: 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.
