Abstract
A vehicle exhaust system includes an outer housing defining an internal cavity surrounding an axis, an inlet baffle configured to direct engine exhaust gas into the internal cavity, and an injector that is configured to spray a fluid into the internal cavity to mix with engine exhaust gas. An inner wall is spaced radially inward of an inner surface of the outer housing to define a gap. The inner wall has an impingement side facing the axis and a non-impingement side facing the gap. At least one heat transfer element is positioned within the gap and in is contact with at least one of the inner surface of the outer housing and the non-impingement side of the inner wall to transfer heat through the inner wall to the impingement side to reduce spray deposit formation.
