Heat exchanger for exhaust gas cooling has structural elements arranged so that duct has internal variable heat transfer increasing in direction of flow

摘要

The heat exchanger has at least one duct for a flow traveling from an inlet cross section to an outlet cross section. It has internal structural elements to increase heat transfer. The structural elements (11) are variably arranged and/or configures in the direction of flow (P) so that the duct (10) has internal variable heat transfer increasing in the direction of flow.
