Abstract
An EGR cooler including tubes and a shell enclosing the tubes. Cooling water is supplied into and discharged from the shell. Exhaust gas is guided from a diesel engine into the tubes for thermal exchange of the exhaust gas with the cooling water. A bypass flow path for guiding the cooling water is constituted within the shell so as to prevent stagnation of the cooling water in the shell.
