Abstract: An annular heat exchanger for cooling hot gases comprises an inner shell, an intermediate shell and an outer shell. Where the heat exchanger is integrated with a catalytic converter for treatment of hot exhaust gases in a motor vehicle, the inner shell contains a catalyst for treatment of the exhaust gases. Inner and outer gas flow passages are provided between the shells, and a coolant flow passage is provided, either on the outer surface of the outer shell, or between the intermediate and outer shells. The exhaust gases change direction twice as they pass through the heat exchanger, and the annular structure of the heat exchanger provides a large surface area, and a large flow section, relative to volume, and thereby provides effective heat exchange without significantly increasing space requirements.

Abstract: A manifold structure is defined by a pair of stacked plates which define a void: one of these plates has three or more aperture-surrounding bosses which project into the void; the other of these plates has a plurality of protuberances. Each of the protuberances engages between a respective pair of the bosses. A heat exchange element is formed of a plurality of stacked plates, these plates defining a stack of tubes. The tube stack interiorly defines a plurality of U-shaped passages, these passages being distinct from one another. Each tube defines a respective one of the U-shaped passages and is received in plug-fit relation by a respective one of the bosses. The tubes, bosses and protuberances separate the void into a pair of manifolds. Each of the U-shaped passages leads from one of the manifolds to the other of the manifolds.
