An exhaust gas cooler comprising an inlet chamber shaped to restrict exhaust gas flow to certain exhaust gas passages provided therein is disclosed. The inlet chamber may comprise a flow deflector which deflects a proportion of exhaust gas into, for example, the upper exhaust gas cooling passages thus restricting flow to lower exhaust gas cooling passages. In one embodiment the flow deflector is rotatably mounted and can also function as a bypass valve. Alternatively apertures provided within plates which can collectively define the inlet chamber may be of a differing size to restrict exhaust gas flow to certain exhaust gas cooling passages. A more balanced flow through the various exhaust gas cooling passages results increasing heat-exchange efficiency of the exhaust gas cooler.
