Shell (10) according to Claim 1, wherein the 2nd part (35) has two said side plate (51, 52), referred to as 1st and 2nd side plate (51, 52), by the 1st side plate (51) defined interface (53, 54), referred to as 1st interface (53), can be used for receiving the fluid to be cooled to the inlet header (75), the 2nd side plates (52) define interface (53, 54), called 2nd interface (54), for receiving the fluid to be cooled the outlet header (76). 3. Housing (10) as in Claim 1 or Claim 2, wherein the 2nd part comprises a bottom (36), the bottom (36) of the plurality of stack with intent to the face (2) of the end plate (37), the bottom (36) and one or a plurality of side plates (51, 52) to form a unit assembly. 4. According to the foregoing claim wherein the housing (10), wherein the interface (53, 54) defining an edge (55), with an opening in the middle the stated edge (57), said opening (57) allowing the fluid to be cooled to enter and/or leave the shell (10). 5. Shell (10) according to Claim 4, wherein the edge (55) of the collar (56) define, the states leads towards the housing (10) internal bias, to define an opening (57) and can be used for to be cooled with a fluid header (75, 76) collaboration. 6. Shell (10) according to Claim 5, wherein the collar (56) a part of the contact (the 56 [...]) 2nd part (35) of the bottom (36) of the side (33, 34). 7. According to the foregoing claim wherein the housing (10), wherein the 1st part (5) includes two side walls (11, 12) and top wall (13). 8. Shell (10) according to Claim 7, wherein one or a plurality of lateral walls (11, 12) and/or the top wall (13) each having a folded edge (30), the folded edges at least partially in contact with the side plate (51, 52) of one surface (65), the surface (65) facing the volume and is called internal surface within the body. 9. Shell (10) according to Claim 8, wherein the top wall (13) of the folding (30) is connected with two side walls (11, 12) of the folded edge (30). 10. To 9 the shell states (10) according to Claim 7, wherein the 2nd part (35) of the bottom (36) has a central portion (38) and two longitudinal end portions (39, 40), the longitudinal end of a limited relative to the central portion (38) of the shoulder (41), each shoulder (41) allows the 1st part (5) of the side wall (11, 12) a distal end (21, 26) is situated in the housing (10) defines a flat plane which extends symmetrically on the outside. 11. A stacked plate-type heat exchanger (1), according to any of the of the housing (10) and a plurality of stack (2), the plurality of stacked plate configuration used for the fluid to be cooled and coolant circulating, and is located in the casing (10) internal. 12. Exchanger (1) according to Claim 11, wherein each plate (2) with heat-exchange area (6) and a bypass area (7), the heat exchange area to be cooled is intended to facilitate the heat exchange between the fluid and coolant, the by-pass area to allow the fluid to be cooled by bypassing the heat exchange area (6), the one or more fold-down side plate forming a part of one or more of the baffle plate (70), to promote the circulation of the fluid to be cooled through the exchange of regional.
