摘要：
The invention relates to an air-cooled exhaust gas heat exchanger, in particular exhaust gas cooler (1) for motor vehicles comprising channels (exhaust gas channels) which can be cross-flown by the exhaust gas of an internal combustion engine, between which ribs (4) for air cooling are arranged. According to the invention, the exhaust gas channels are embodied as tubes, in particular as flat tubes (3), which form the ribs (4) of a rib tube block (2) and the tube (3) has tube ends (3a) which are received in the collecting vessels (5) for the exhaust gas.
