のアフタークーラ装置。A radiator for the aftercooler is used in an internal combustion engine in which an aftercooler is installed in the passage that leads pressurized air from the exhaust turbine supercharger to the intake manifold, and the aftercooler cools the pressurized air before flowing it to the intake manifold. Divide the upper tank into multiple chambers using partition walls, connect inlet conduits in parallel to each of the divided chambers, and connect these inlet conduits to a single conduit leading to the turbocharger. One or more of them is provided with an on-off valve that closes when the engine speed drops below a predetermined speed, and no valve is provided to open/close the pressurized air from the supercharger when the engine speed drops below a predetermined speed. An aftercooler device for an internal combustion engine, characterized in that the inlet conduit leads to one or more of the divided chambers of an upper tank of a radiator.
