A substantially planar heat exchanger for regulating the temperature of objects using a fluid coolant includes a bottom plate, a top plate, a fin insert sealed therebetween and a coolant inlet and outlet. The fin insert may include a plurality of substantially flattened omega-shaped or teardrop-shaped fins, which enhances the transfer of heat from the top and/or bottom plates into the fin insert. The omega-shaped fin inserts enhance the contact surface area between the plates and the insert to improve thermal migration therebetween. The fin insert may be constructed, for example, by forming convolutions in a sheet of metal, and compressing the convolutions laterally inwardly and vertically inwardly.

Heat exchangers with improved heat transfer fin insert

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.

Finned coaxial cooler

An exhaust gas recirculation cooler for internal combustion engines and a method of forming same. One or more cooler tubes incorporate a flexible section, comprised of one or more integrally formed convolutions, with a tube and fin architecture. The exhaust gas recirculation cooler provides thermal compensation, on a per-tube basis, with the flexible sections of the one or more cooler tubes individually displacing upon the thermal expansion of any of the respective tubes.
