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.
