EXHAUST GAS HEAT EXCHANGER IN AN EXHAUST GAS RECIRCULATION ASSEMBLY

摘要

The exhaust gas heat exchanger in exhaust gas recirculation arrangement has flow-conducting units, which comprises a curved plate, in which channels are formed with inlets and outlets. The channels extend in longitudinal direction or in transverse direction of the waste-gas heat-exchanger. Some of the channels have an unequal process. Length variations are allowed between a stack and housing (11). The stack consists of flat pipes, which contain a turbulator. A coolant channel (5) is arranged between two flat pipes, which are provided with the flow-conducting units.
