Multi-Circuit Heat Exchanger

Abstract

The present invention relates to an exchanger comprising at least two circuits, this exchanger comprising: a series of tubes for the circulation of fluid of one or other of the two circuits, at least two collector rings, each connected to the opposite ends of the tubes, said tubes opening respectively into said collector rings, a partition provided in each of said collector rings defining at least one separation in order to isolate the first circuit from the second circuit of fluid, a mechanical connection means connecting the structure of the inlet chamber to the collection chamber is designed to reduce significantly the structural mechanical stresses existing in the separation between the two circuits, characterized in that the mechanical means consists in a total or partial closing off of at least one tube situated next to the partitions.
