Abstract
A heat exchanger associated with an exhaust gas recirculation system cools the exhaust gasses before directing them to an internal combustion engine. The heat exchanger can include a tube core having a plurality of exhaust gas tubes that can extend along a longitudinal axis. The tube core can also include a plurality of coolant channels disposed between and spacing apart the plurality of exhaust gas tubes. A coolant inlet line is disposed about at least a portion of the tube core to direct coolant inwardly toward the coolant channels. At least a portion of the coolant can converge approximately at the longitudinal axis line.
