Abstract

A heat exchanger for a motor vehicle exhaust includes an outer tubular body and an inner tubular body. The outer tubular body has peripheral sidewalls, an interior cavity, a first end and a second end. The inner tubular body has fluid impervious sidewalls formed out of a single length of conduit wound in a spiral coil. The spiral coil has an exterior surface and an interior surface. The inner tubular body is disposed within the interior cavity of the outer tubular body spaced from the peripheral sidewalls. This provides a first flow channel between the exterior surface of the inner tubular body and the peripheral sidewalls of the outer tubular body, and a second flow channel along the interior surface of the inner tubular body. The conduit of the spiral coil has an inlet end and an outlet end, whereby fluid is circulated through the coil.
