Abstract
An exhaust gas recirculation (EGR) cooler for cooling exhaust gas via a coolant includes at least one channel having an inlet and an outlet, and a casing defining a cooling chamber for carrying the coolant around the at least one channel. The exhaust gas is flowable through the at least one channel from the inlet to the outlet. At least a portion of the at least one channel is variable between a fully compressed position and an uncompressed position. The casing includes a coolant inlet and a coolant outlet through which the coolant enters and exits the cooling chamber. The casing also includes an exhaust gas inlet from which the exhaust gas enters the at least one channel, and an exhaust gas outlet into which the exhaust gas exits the at least one channel.
