Abstract (en)
[origin: EP0974804A2] The flow channels (2) of the heat exchanger are longer than the flow channels (3) and extend through the collection chamber (4) having inlets and outlets (8, 9). In region (l), in which both flow channels run parallel to each other, the heat exchanger does not have a housing. Heat exchanger , especially waste gas heat exchanger, consists of a stack of heat exchange plates forming divided flow channels running parallel to each other, with collection chambers, and inlet and outlet for the waste gas and for liquid coolant. The flow channels (2) of the heat exchanger are longer than the flow channels (3) and extend through the collection chamber (4) having inlets and outlets (8, 9). In region (l), in which both flow channels run parallel to each other, the heat exchanger does not have a housing.
