Claim:
1. A heat exchanger for exchanging heat between a first fluid and a second fluid, said heat exchanger comprising: a heat exchange core for a heat exchange between the first and second fluids, comprising first circulation channels for the first fluid and second circulation channels for the second fluid between said first circulation channels, an inlet collector box for the first fluid and an outlet collector box for the first fluid, into which ends of said first circulation channels open out, and an inlet connection piece for the second fluid and an outlet connection piece for the second fluid, wherein said inlet and outlet collector boxes for the first fluid are fixed on a first side of said heat exchange core and are separated by a deflector, wherein said heat exchanger further comprises an intermediate collector box communicating with said first circulation channels to create a U-circulation of the first fluid in said first circulation channels, wherein said heat exchanger further comprises at least one wall fixed on a second side of said heat exchange core adjacent to said first side and said inlet and outlet connection pieces for the second fluid are disposed at one end of said wall, wherein said inlet connection piece is separated from said outlet connection piece on said wall wherein said heat exchanger further comprises an intermediate compartment communicating with said second circulation channels for a U-circulation of the second fluid in said second circulation channels, and wherein said intermediate collector box and said intermediate compartment are disposed on sides of said heat exchange core, with said side of said heat exchange core having said intermediate collector box perpendicular to said side of said heat exchange core having said intermediate compartment, and wherein said heat exchange core comprises a stack of tubes, of which at least two tubes are joined in such a manner that:
