An improved heat exchanger suitable for use as a pre-cooler in an internal combustion engine exhaust gas recirculation system includes an inner heat exchange tube for exchanging heat between a gas and a coolant. A tubular outer body surrounds at least part of the inner heat exchange tube. Coolant flows through a cavity formed between the outer surface of the inner heat exchange tube and the inner surface of the tubular outer body, cooling the gas flowing through the inner heat exchange tube. The inner heat exchange tube surrounds a rolled, cylindrically-shaped corrugated sheet of material forming a plurality of fins. At least one of the fins is in contact with an inner surface of the inner heat exchange tube. The tubular outer body surrounds two or more inner heat exchange tubes, each inner heat exchange tube surrounding a respective plurality of fins.

A heat exchanger for cooling heated gas using a liquid coolant includes a tubular housing with one or more intake apertures circumferentially spaced around a coolant distribution portion of the housing. A tube retention cap sealedly engages the front end of the tubular housing, and includes at least one gas tube orifice. An annular coolant chamber surrounds the coolant distribution portion, which distributes liquid coolant around the intake apertures and directs coolant into the cavity and within the tubular housing. Positioned within the tubular housing is at least one elongated gas tube, which is sealedly engaged with the tube orifice. Liquid coolant flowing in, through a coolant inlet, is directed around the annular coolant chamber and distributed into the cavity of the tubular housing, immersing the elongated gas tube and facilitating heat exchange from the heated gas flowing through the elongated gas tubes immersed within the liquid coolant.
