Patent ID: 8081729

Claim:
A heat exchanger assembly for exchanging heat between a first fluid and a second fluid, the assembly comprising: an outer enclosure presenting a central axis and provided with at least one inlet and outlet for the first fluid and with at least one inlet and outlet for the second fluid; a central manifold extending along the central axis and communicating with one of the inlet and the outlet for the first fluid; an annular manifold disposed around the central manifold and communicating with the other one of the inlet and the outlet for the first fluid; a plurality of heat exchangers distributed around the central axis and radially interposed between the central manifold and the annular manifold; a plurality of axial inlet manifolds communicating with the inlet( 8 ) for the second fluid, and a plurality of axial outlet manifolds communicating with the outlet for the second fluid, the axial inlet and outlet manifolds being circumferentially interposed between the heat exchangers; and each heat exchanger comprises a plurality of channels for flow of the first fluid between the central and annular manifolds, and a plurality of channels for flow of the second fluid from at least one inlet manifold towards at least one outlet manifold; the assembly including an inlet chamber provided at a first axial end of the heat exchangers and putting the inlet(s) for the second fluid into communication with at least a plurality of axial inlet manifolds.
