Abstract

The twin path exhaust gas circulation cooling device comprises two long adjacent chambers (CR,CD) each defined by an individual casing (2,3). The first (CR) is fitted with cooling fluid tubes (4) and defines the first circulation path and the other defines the second circulation path through which the gas must only be subjected to a minimum lower temperature. The two chambers are separated by a heat insulation partition (6).
