Said inlet (5) and outlet (7) collector boxes for the first fluid are separated by a deflector (13) and said exchanger moreover comprises an intermediate collector box (21) communicating with said first channels to create a U-circulation of the first fluid in said first channels. Said exchanger comprises an intermediate compartment (39) communicating with said second channels for a U-circulation of the second fluid in said second channels. ## Claims ### Claim 1 A heat exchanger for exchanging heat between a first fluid and a second fluid, said exchanger comprising: a heat exchange core for a heat exchange between the first and the second fluids, comprising first circulation channels of the first fluid and second circulation channels of the second fluid between said first channels, an inlet collector box for the first fluid and an outlet collector box for the first fluid, into which the ends of said first 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 core and are separated by a deflector and said exchanger further comprises an intermediate collector box communicating with said first channels to create a U-circulation of the first fluid in said first channels, wherein said exchanger further comprises at least one wall fixed on a second side of said 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, being separated one from the other, and said exchanger further comprises an intermediate compartment communicating with said second channels for a U-circulation of the second fluid in said second channels, and wherein said intermediate collector box and said intermediate compartment are disposed on sides of said core perpendicular one to the other. ### Claim 2 (depends on 1) The heat exchanger according to claim 1, further comprising a joint collector box divided by said deflector into two compartments to form said inlet box and said outlet box. ### Claim 3 (depends on 1) The heat exchanger according to claim 1, wherein the inlet collector box and the outlet collector box of the first fluid are realized by two different parts. ### Claim 4 (depends on 1) The heat exchanger according to claim 1, wherein said core comprises a stack of tubes, of which at least two tubes are joined in such a manner that: the lateral surfaces of said joined tubes are located substantially opposite the junction between said connection pieces, and that said deflector separating said collector boxes is located substantially opposite the junction between said joined tubes. ### Claim 5 (depends on 1) The heat exchanger according to claim 1, wherein the intermediate collector box communicating with the assembly of said first channels is disposed on a third side of said core opposite said first side, for U-circulation of the first fluid. ### Claim 6 (depends on 1) The heat exchanger according to claim 1, wherein the intermediate compartment communicating with the assembly of said second channels, for the U-circulation of the second fluid, is disposed on an end of said wall, opposite said connection pieces. ### Claim 7 (depends on 1) The heat exchanger according to claim 1, wherein said core exhibits a general form which is substantially parallelepiped with two end sides, two small lateral sides and two large lateral sides, and in which said first side is a small lateral side and said second side is a large lateral side of said core. ### Claim 8 (depends on 1) The heat exchanger according to claim 1, wherein the exchanger is configured for the cooling of charge air of a motor vehicle engine. ### Claim 9 (depends on 8) The heat exchanger according to claim 8, wherein the first fluid is charge air and the second fluid is glycol water. ### Claim 10 (depends on 2) The heat exchanger according to claim 2, wherein said core comprises a stack of tubes, of which at least two tubes are joined in such a manner that: the lateral surfaces of said joined tubes are located substantially opposite the junction between said connection pieces, and that said deflector separating said collector boxes is located substantially opposite the junction between said joined tubes. ### Claim 11 (depends on 3) The heat exchanger according to claim 3, wherein said core comprises a stack of tubes, of which at least two tubes are joined in such a manner that: the lateral surfaces of said joined tubes are located substantially opposite the junction between said connection pieces, and that said deflector separating said collector boxes is located substantially opposite the junction between said joined tubes. ### Claim 12 (depends on 2) The heat exchanger according to claim 2, wherein the intermediate collector box communicating with the assembly of said first channels is disposed on a third side of said core opposite said first side, for U-circulation of the first fluid. ### Claim 13 (depends on 3) The heat exchanger according to claim 3, wherein the intermediate collector box communicating with the assembly of said first channels is disposed on a third side of said core opposite said first side, for U-circulation of the first fluid. ### Claim 14 (depends on 4) The heat exchanger according to claim 4, wherein the intermediate collector box communicating with the assembly of said first channels is disposed on a third side of said core opposite said first side, for U-circulation of the first fluid.
