The heat exchanger block has a tube bottom including a deformable hook, and the side part includes a tab provided complementary to a corner region of the tube bottom. The tab has a section, that abuts on a front side of the tube bottom, that includes a through opening or depression. A material portion of the hook is displaced through the through opening or depression via a graining in an assembled state, such that the axes of the through opening and the graining are offset and parallel to one another.

Abstract: A heat exchanger may include a plurality of pipe bodies arranged between two side parts. At least one side part may have at least one predetermined breaking point and at least one heat expansion compensator. The at least one side part may include at least one aperture, which may lead from the at least one predetermined breaking point to the at least one heat expansion compensator.

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.
