Abstract
A heat insulator for an intake manifold of an air-cooled charge air cooler is a rectangular box placed inside the intake manifold housing. The charge air coming into the intake manifold is passed to the inside of the box by a liner in the housing tube. One side of the box has a plurality of openings with outwardly extending walls for abutting directly with the tubes or plates of the heat exchanger section of the cooler. The box has outwardly extending protrusions for positioning the box inside the intake manifold housing, the protrusions being such that direct heat transfer between the box and the housing is minimal and the heat conduction through the housing wall is sufficient to keep the housing temperature significantly lower than the charge air temperature. The box is not air tight to allow relatively thin material to be used since there is no pressure differential between the outside and the inside of the box.
