Title:
EGR COOLER
Document Type and Number:
WIPO Patent Application WO/2018/110351
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an EGR cooler such that an improvement in separation of liquid contained in EGR gas can be achieved while an increase in device size is suppressed. The EGR cooler has: a heat-exchange unit (21) for cooling EGR gas returning from an exhaust path (3) of an internal combustion engine (1) to an intake path (2); and an outflow pipe (23) providing communication between an exhaust port of the heat-exchange unit (21) and the intake path (2), having therein a swirl flow generation ribbon (30) formed of a helical plate member and causing the EGR gas to swirl, and having an exhaust port (26c) and a drainage port (25c). The swirl flow generation ribbon (30) has a configuration in which first and second edges (32a, 32b) connecting a first end point (31a) set on one radial outer side, a second end point (31b) set on the other radial outer side, and a center end point (31c) disposed on an axis (O) at a position closer to the heat-exchange unit (21) than the first and second end points (31a, 31b) are disposed on an end section (31).
