Abstract
An EGR cooler core has multiple tubes for conveying engine exhaust gas. Tube inlets are joined to a flat inlet header plate at tube/header plate joints in a flat zone of the inlet header plate. An endless groove in the inlet header plate circumscribes the joints while reducing a constant nominal thickness of the header plate in the flat zone along the groove without creating an opening through the header plate. This gives some compliance to the flat zone for mitigation of stresses induced by tube growth.
