Heat exchanger

The utility model relates to a heat exchanger which comprises a tube-rib-module (4), which is enclosed through two collecting tanks (2, 3). The ends of the tubes (5) are inserted in the bottoms (14) of the collecting tanks (2, 3) and the bottoms (14) are closed with covers (13). A partition wall (12...

Zusammenfassung:	The utility model relates to a heat exchanger which comprises a tube-rib-module (4), which is enclosed through two collecting tanks (2, 3). The ends of the tubes (5) are inserted in the bottoms (14) of the collecting tanks (2, 3) and the bottoms (14) are closed with covers (13). A partition wall (12) secured to each cover (13) is formed transverse to longitudinal extension portions of the collecting tanks (2, 3) and divides the interior space of the collecting tanks (2, 3) into two subchambers (21, 22). First stress decoupling devices (20) are formed in the bottoms (14) and/or a second stress decoupling device (11) is formed in the area of the partition wall (12) in the cover (13) of at least one collecting tank (2,3). The heat exchanger prevents great structural changes for compensating temperature-induced stresses.
